Description

Technical Field

[0001] This utility model belongs to the field of lock technology, specifically relating to an outward-opening child lock. Background Technology

[0002] Door and window locks are an important part of home security. They must not only ensure anti-theft performance, but also take into account functions such as child safety, anti-pinch, and emergency escape. To prevent children from causing accidental injuries due to misoperation or curiosity, locks are designed with child safety features. Although door and window locks on the market currently have child safety functions, they still have shortcomings in terms of ease of use and technical reliability, which affects the actual user experience. Existing child locks are cumbersome to operate, inconvenient for parents to use, and have complicated unlocking steps: some locks require pressing and rotating at the same time, making it difficult to operate with one hand. Utility Model Content

[0003] This addresses the technical problem of inconvenient child lock operation in existing locks.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an outward-opening child lock, comprising a lock body and a handle. The lock body is provided with a gear, a fork, a limiting ring, and a decorative cover. The gear and the fork are provided with transmission teeth at their contacting ends. The decorative cover is provided on one side surface of the lock body. One end of the limiting ring passes through the decorative cover and is inserted into the lock body. The gear passes through the limiting ring and is connected to the handle. The gear is provided with a locking groove, and a ball is provided in the locking groove. The limiting ring is provided with an opening, and the decorative cover is provided with a positioning groove. By rotating the decorative cover, the ball can be controlled to move through the opening in the locking groove and the positioning groove.

[0005] Furthermore, a base plate is provided on one side of the lock body, and a movable groove is provided in the base plate, with one end of the fork plate located in the movable groove.

[0006] Furthermore, the lock body is also equipped with a connector, which is fitted onto the outside of the gear.

[0007] Furthermore, the connector is equipped with a spring and a limiting ball, and the gear has several limiting grooves on its outer periphery.

[0008] Furthermore, one end of the spring abuts against the side wall of the connector, and the other end abuts against the limiting ball, which is located in the limiting groove of the gear.

[0009] This utility model has the following advantages: When the lock is not in the child lock state, the positioning groove of the decorative cover is located at the bottom of the ball. The ball leaves the locking groove in the gear and falls into the positioning groove of the decorative cover from the opening of the limiting ring. At this time, there is no restriction between the gear and the limiting ring. Rotating the handle drives the gear to rotate, and the other end of the gear meshes with the fork, thereby driving the fork to move up and down to realize the lock opening and closing. When the lock needs to be in the child lock state, rotating the decorative cover causes the ball to leave the positioning groove and fall into the opening of the limiting ring and the locking groove of the gear. The gear and the limiting ring are engaged by the ball. At this time, rotating the handle will cause the gear and the limiting ring to be locked by the ball and unable to rotate, thus realizing the function of the child lock and preventing children from accidentally opening doors and windows, avoiding dangers such as falling, being pinched, or getting lost.

Detailed Implementation

[0015] like Figures 1 to 4 As shown, an outward-opening child lock includes a lock body 10 and a handle 20. The lock body 10 has a gear 30, a fork 40, a limiting ring 50, and a decorative cover 60. The gear 30 and the fork 40 are provided with transmission teeth 41 at their contacting ends. The decorative cover 60 is provided on one side surface of the lock body 10. One end of the limiting ring 50 passes through the decorative cover 60 and is inserted into the lock body 10. The gear 30 passes through the limiting ring 50 and is connected to the handle 20. The gear 30 has a locking groove 31, and the locking groove 31 has a ball 32. The limiting ring 50 has an opening 51, and the decorative cover 60 has a positioning groove 61. By rotating the decorative cover 60, the ball 32 can be controlled to move through the opening 51 in the locking groove 31 and the positioning groove 61.

[0016] When in use, with the child lock not engaged, the positioning groove 61 of the decorative cover 60 is located at the bottom end of the ball bearing 32. The ball bearing 32 leaves the locking groove 31 in the gear 30 and falls into the positioning groove 61 of the decorative cover 60 through the opening 51 of the limiting ring 50. At this time, there is no restriction between the gear 30 and the limiting ring 50. Rotating the handle 20 drives the gear 30 to rotate, and the other end of the gear 30 meshes with the fork 40, thereby driving the fork 40 to move up and down. When the child lock is activated, the decorative cover 60 is rotated to disengage the ball bearing 32 from the positioning groove 61 and allow it to fall into the opening 51 of the limiting ring 50 and the locking groove 31 of the gear 30. The gear 30 and the limiting ring 50 are engaged by the ball bearing 32. At this time, rotating the handle 20 will prevent the gear 30 and the limiting ring 50 from rotating due to the ball bearing 32, thus realizing the function of the child lock and preventing children from accidentally opening doors and windows, avoiding dangers such as falling, being pinched, or getting lost.

[0017] The lock body 10 has a base plate 11 on one side, and a moving groove 12 in the base plate 11. One end of the fork 40 is located in the moving groove 12. When the handle drives the fork 40 to move up and down through the gear 30 to control the lock switch, the fork 40 moves up and down in the moving groove 12 in the base plate 11.

[0018] The lock body 10 also includes a connector 70, which is fitted onto the outside of the gear 30. The connector 70 contains a spring 71 and a limiting ball 72. The gear 30 has several limiting grooves 33 on its outer periphery. One end of the spring 71 abuts against the side wall of the connector 70, and the other end abuts against the limiting ball 72. The limiting ball 72 is located in the limiting groove 33 of the gear 30. When the handle 20 drives the gear 30 to rotate and open / close the lock, the spring 71 pushes the limiting ball 72 into the limiting groove 33 of the gear 30 to achieve a positioning function.

[0019] In summary, the outward-opening child lock of this utility model can be opened by rotating the decorative cover 60 to control the up-and-down movement of the ball 32. It has a simple structure and is easy to operate, preventing children from accidentally opening doors and windows and avoiding dangers such as falling, getting pinched, or getting lost.
