Abstract

A press lock includes a lock plate, and a locking member including a lower mounting plate, a pressing cap, and a lock lever. An elastic retention member configured to maintain the lock lever in a balanced position and a guide block with a guide groove are further included, where an end of a hook connected to the pressing cap is received in the guide groove. When the end of the hook is located at a lower locking position of the guide groove, the pressing cap acts on the elastic retention member to allow the lock lever to move downwards to fit with the lock plate, and when the end of the hook is located at an upper locking position of the guide groove, the lower mounting plate acts on the elastic retention member to allow the lock lever to move upwards and disengage from the lock plate.

First claim

What is claimed is:

1 . A press lock, comprising:
a lock plate; a locking member configured to lock the lock plate, comprising:
a lower mounting plate, which is located above the lock plate;
a pressing cap and a lock lever which are located above the lower mounting plate, the pressing cap being connected with a hook, wherein the lower mounting plate is formed with a lower penetration hole for the lock lever to pass therethrough;
an elastic retention member, which is configured to maintain the lock lever in a balanced position; and
a guide block provided with a guide groove, the guide groove having an upper locking position and a lower locking position, wherein a free end of the hook is received in the guide groove, and wherein the free end of the hook is configurated to switch once between the upper locking position and the lower locking position at each time the pressing cap is pressed,
wherein the lock lever is configured to move toward the lock plate to fit with a locking portion on the lock plate, with the pressing cap acting on the elastic retention member, when the free end of the hook is located at the lower locking position; and wherein the lock lever is further configured to move away from the lock plate to disengage from the lock plate, with the lower mounting plate acting on the elastic retention member, when the free end of the hook is located at the upper locking position.

2 . The press lock according to claim 1 , wherein the elastic retention member comprises an upper elastic member and a lower elastic member, two ends of the upper elastic member are configured to act on the pressing cap and the lock lever, respectively, to exert a downward force on the lock lever, and two ends of the lower elastic member are configured to act on the lower mounting plate and the lock lever, respectively, to exert an upward force on the lock lever.

3 . The press lock according to claim 2 , wherein a side wall of the lock lever is provided with a bump, wherein two ends of the upper elastic member are respectively abutted against an upper side of the bump and the pressing cap, and two ends of the lower elastic member are respectively abutted against a lower side of the bump and the lower mounting plate.

4 . The press lock according to claim 2 , wherein an elasticity coefficient of the upper elastic member is greater than that of the lower elastic member.

5 . The press lock according to claim 2 , wherein the upper elastic member and/or the lower elastic member are in form of tower springs with a narrower end thereof acting on the lock lever.

6 . The press lock according to claim 1 , wherein the pressing cap is provided with an avoidance hole corresponding to the lock lever.

7 . The press lock according to claim 1 , further comprising an upper mounting plate, which is provided with an upper penetration hole to guide the pressing cap.

8 . The press lock according to claim 7 , wherein an outer side of the pressing cap is provided with a retaining rim to prevent the pressing cap from falling out of the upper penetration hole.

9 . The press lock according to claim 7 , wherein two ends of the lower mounting plate are connected to the upper mounting plate, and the middle portion of the lower mounting plate is formed with an accommodating space for accommodating the pressing cap, the lock lever, the elastic retention member, the hook and the guide block.

10 . The press lock according to claim 1 , wherein the locking portion is in form of a lock hole or a notch.

11 . The press lock according to claim 1 , wherein two guide blocks are provided and arranged oppositely, and two hooks are correspondingly provided, with each of the two hooks fitting with one of the guide blocks.

12 . The press lock according to claim 1 , wherein the guide groove comprises a first groove and a second groove which are respectively located on two sides of a connecting line between the upper locking position and the lower locking position, wherein the first groove is configured to unidirectionally guide the end of the hook from the upper locking position to the lower locking position, and the second groove is configured to unidirectionally guide the end of the hook from the lower locking position to the upper locking position.

13 . The press lock according to claim 12 , wherein a depth of the first groove at the upper locking position is greater than a depth of the second groove at the upper locking position, a depth of the first groove at the lower locking position is less than a depth of the second groove at the lower locking position, and the free end of the hook is configured to be always abutted against a bottom of the first groove or a bottom of the second groove.

14 . The press lock according to claim 12 , wherein the first groove comprises a first groove section and a second groove section which are communicated with each other, with the ends, away from each other, of the first groove section and the second groove section being respectively connected to the upper locking position and the lower locking position, and the second groove comprises a third groove section and a fourth groove section which are communicated with each other, with the ends, away from each other, of the third groove section and the fourth groove section being respectively connected to the upper locking position and the lower locking position, wherein compared with the lower locking position, a connecting position between the first groove section and the second groove section and a connecting position between the third groove section and the fourth groove section are closer to the lower mounting plate; and
wherein at the connecting position between the first groove section and the second groove section, a groove depth of the second groove section is deeper, at the connecting position between the third groove section and the fourth groove section, a groove depth of the third groove section is deeper, and the free end of the hook is always abutted against a bottom of the first groove section, a bottom of the second groove section, a bottom of the third groove section or a bottom of the fourth groove section.

15 . A stage light fixture, comprising the press lock according to claim 1 , and further comprising a light head configured to project light beams, a support arm configured to support rotation of the light head, and a base configured to support rotation of the support arm, wherein the press lock is configured to lock the light head or the support arm.
