Abstract

An assembled-type fastener unit includes a base, a handling member movably fitted in the base, and a locking device movably received in the handling member. The handling member can be operated for the locking device to extend out of the base to form a locked state or for the locking device to retract into the base to form an unlocked state. To use the fastener unit, the base is firstly connected to an object. Then, the handling member is operated for the locking device to extend out of the base and lock to a target object to form the locked state; or the handling member can be operated for the locking device to retract into the base to separate from a target object and form the unlocked state. Thus, at least two objects can be repeatedly and quickly connected to or disconnected from one another using the fastener unit.

First claim

What is claimed is:

1. An assembled-type fastener unit, comprising:
a base, a handling member and a locking device; the handling member being movably fitted in the base, and the locking device being movably received in the handling member; the handling member being operable for the locking device to extend out of the base to form a locked state, and the handling member also being operable for the locking device to retract into the base to form an unlocked state;
wherein the base includes a first opening and a second opening; the first opening and the second opening being correspondingly formed on two opposite side surfaces of the base; and the guide path of the handling member being located between the first and the second opening;
wherein the locking device includes a locking element and a locating element; the locating element extending through the handling member and being engaged with the locking element; the handling member being operable to control the locating element, such that the locking element is brought to extend out of the base to form the locked state; and the handling member also being operable to control the locating element, such that the locking element is brought to retract into the base to form the unlocked state.

2. The assembled-type fastener unit according to claim 1 , wherein the base includes at least one fixing section.

3. The assembled-type fastener unit according to claim 1 , further comprising an elastic element located between the base and the handling member; and the elastic element having an end pressed against the base and another end pressed against the handling member.

4. The assembled-type fastener unit according to claim 1 , wherein the guide path is obliquely and slantly formed on the handling member.

5. The assembled-type fastener unit according to claim 1 , wherein, when the handling member is operated for the locking device to form the locked state, the locking element has an end extended out of the base through the first opening and the locating element is moved in the handling member to an end of the guide path; and when the handling member is operated for the locking device to form the unlocked state, the projected end of the locking element retracts into the base via the first opening and another end of the locking element extends out of the base through the second opening, and the locating element is moved in the handling member to another end of the guide path.

6. The assembled-type fastener unit according to claim 1 , wherein the handling member has an anti-slip section provided on an outer end surface thereof.

7. The assembled-type fastener unit according to claim 1 , wherein the locating element moves on the guide path when the handling member is moving in the base, and the locking element is brought to move when the locating element moves.

8. The assembled-type fastener unit according to claim 1 , further comprising an elastic element located between the base and the handling member; the elastic element having an end pressed against the base and another end pressed against the handling member, so that the handling member is elastically reciprocatingly movable in the base; the handling member being operable for the locking device to extend out of the base to form the locked state; and the handling member also being operable for the locking device to retract into the base to form the unlocked state.

9. The assembled-type fastener unit according to claim 1 , further comprising an elastic element located between the base and the handling member; the elastic element having an end pressed against the base and another end pressed against the handling member, so that the handling member is elastically reciprocatingly movable in the base; the locking device extending out of the base to form the locked state when the elastic element is elastically extended to release an elastic force; and the locking device retracting into the base to form the unlocked state when the elastic element is elastically compressed.

10. The assembled-type fastener unit according to claim 1 , wherein, when the handling member is operated for the locking device to form the locked state, the locking element has an end extended out of the base through the first opening and the locating element is moved in the handling member to an end of the guide path; and when the handling member is operated for the locking device to form the unlocked state, the projected end of the locking element retracts into the base via the first opening, and the locating element is moved in the handling member to another end of the guide path.

11. The assembled-type fastener unit according to claim 1 , wherein the locating element being movably fitted in the guide path, and the locking element being movable according to a movement of the locating element in the guide path.

12. The assembled-type fastener unit according to claim 1 , wherein the guide path is formed of two vertically spaced symmetrical channels, and the locking element being received in the guide path.

13. The assembled-type fastener unit according to claim 1 , wherein the locking device includes the locking element and the locating element engaged with each other; and the locking element and the locating element being assembled to each other or being integrally formed.

14. The assembled-type fastener unit according to claim 1 , wherein the guide path is obliquely and slantly formed on the handling member; and the locking device being movable in the oblique and slant guide path.

15. The assembled-type fastener unit according to claim 1 , further comprising an elastic element located between the base and the handling member; the elastic element having an end pressed against the base and another end pressed against the handling member, so that the handling member is elastically reciprocatingly movable in the base.

16. The assembled-type fastener unit according to claim 1 , wherein the guide path is formed of two vertically spaced symmetrical channels, and the locking device includes the locking element and the locating element engaged with each other; the locating element being movably fitted in the guide path and the locking element being received in the guide path with a right angle included between the locking element and the locating element; and the locking element being movable according to a movement of the locating element in the guide path.

17. An assembled-type fastener unit, comprising:
a base, a handling member and a locking device; the handling member being movably fitted in the base, and the locking device being movably received in the handling member; the handling member being operable for the locking device to extend out of the base to form a locked state, and the handling member also being operable for the locking device to retract into the base to form an unlocked state;
wherein the base includes a first opening;
wherein the locking device includes a locking element and a locating element; the locating element extending through the handling member and being engaged with the locking element; the handling member being operable to control the locating element, such that the locking element is brought to extend out of the base to form the locked state; and the handling member also being operable to control the locating element, such that the locking element is brought to retract into the base to form the unlocked state.

18. An assembled-type fastener unit, comprising:
