Abstract

A lock threaded assembly includes a bolt including a shank formed with a bolt head and having a threaded portion; at least one groove formed on the threaded portion; a nut including a threaded hole configured to secure to the threaded portion of the bolt; at least one trough formed on the threaded hole; and at least one engagement member being an elongated elastic strip body having a securing section and a received section, the securing section and the received section being able to elastically get closer to each other or move away from each other. When the groove is not aligned with the trough, the bolt and the nut are not locked by the engagement member; when the groove is aligned with the trough, the bolt and the nut are elastically locked by the engagement member.

First claim

What is claimed is:

1. A lock threaded assembly comprising:
a bolt having a bolt head and a shank, an outer circumference of the shank being formed with a threaded portion;
at least one groove formed on the circumference of the shank of the bolt;
a nut having a threaded hole having a hole wall, the shank of the bolt being screwed in the threaded hole of the nut;
at least one trough formed on the hole wall of the nut; and
at least one engagement member, the engagement member being an elongated elastic strip body having a securing section and a received section, the securing section and the received section being able to elastically get closer to each other or move away from each other, the received section being disposed in one of the groove of the bolt and the trough of the nut, the securing section is able to engage with the other of the trough of the nut and the groove of the bolt;
wherein relative to the trough the groove is moveable between being aligned with the trough and not aligned with the trough, when the groove is not aligned with the trough, the securing section being moved toward the received section and moved into one of the groove of the bolt and the trough of the nut, when the groove is aligned with the trough, the securing section being moved into the other of the trough of the nut and the groove of the bolt;
wherein the securing section of the engagement member has a connection end connected to the received section and a free end, the securing section is formed in an arcuate shape, a larger gap is formed between a body of the securing section and the received section, while a smaller gap is formed between the free end of the securing section and the received section.

2. The lock threaded assembly as claimed in claim 1 , wherein one or more troughs are formed on the hole wall of the threaded hole of the nut, the shank of the bolt having the groove, the received section of the engagement member being inlaid in the groove, while the securing section of the engagement member being elastically engaged in the trough of the nut.

3. The lock threaded assembly as claimed in claim 2 , wherein an insertion section outward extends from one end of the received section of the engagement member, the groove having a socket inward recessed from the shank, the insertion section of the engagement member being inserted in the socket of the groove.

4. The lock threaded assembly as claimed in claim 1 , wherein the shank of the bolt has one or more grooves, the hole wall of the nut having one trough, the received section of the engagement member being inlaid in the trough, while the securing section of the engagement member being elastically engaged in the groove of the bolt.

5. The lock threaded assembly as claimed in claim 4 , wherein an insertion section outward extends from one end of the received section of the engagement member, the trough having a socket inward recessed from the hole wall of the nut, the insertion section of the engagement member being inserted in the socket of the trough.

6. The lock threaded assembly as claimed in claim 1 , wherein two or more than two grooves are formed on the shank of the bolt, the grooves being formed on the shank at intervals, two or more than two troughs being formed on the hole wall of the nut, the troughs being formed on the hole wall of the nut at intervals, the number of the engagement members being at least two, the received section of one of the engagement members being disposed in the groove of the bolt, the securing section of the engagement member being elastically engaged in the trough of the nut, the received section of the other engagement member being disposed in the trough of the nut, the securing section of the other engagement member being elastically engaged in the groove of the bolt.

7. The lock threaded assembly as claimed in claim 6 , wherein an insertion section outward extends from one end of the received section of the engagement member, the groove having a socket inward recessed from the shank, the insertion section of the engagement member being inserted in the socket of the groove.

8. The lock threaded assembly as claimed in claim 6 , wherein an insertion section outward extends from one end of the received section of the engagement member, the trough having a socket inward recessed from the hole wall of the nut, the insertion section of the engagement member being inserted in the socket of the trough.

9. The lock threaded assembly as claimed in claim 1 , wherein the received section is disposed in the groove of the bolt, an insertion section outward extends from one end of the received section of the engagement member, the groove having a socket inward recessed from the shank, the insertion section of the engagement member being inserted in the socket of the groove.

10. The lock threaded assembly as claimed in claim 1 , wherein an insertion section outward extends from one end of the received section of the engagement member, the trough having a socket inward recessed from the hole wall of the nut, the insertion section of the engagement member being inserted in the socket of the trough.

11. The lock threaded assembly as claimed in claim 1 , wherein the securing section and the received section of the engagement member are side by side positioned, one end of the securing section being connected with one end of the received section.

12. The lock threaded assembly as claimed in claim 1 , wherein the longitudinal direction of the groove is parallel to the axial direction of the shank of the bolt and the longitudinal direction of the trough is parallel to the axial direction of the threaded hole of the nut.

13. The lock threaded assembly as claimed in claim 1 , wherein the engagement member is an elongated elastic metal strip body.
