Technical Field

[0001] The utility model relates to a lock accessory, more specifically to a spring-pushing mechanism for automatically springing open a handle of a lock. Background Art

[0002] In order to facilitate the storage, hiding and protection of the handle when the cabinet door lock is locked, the lock housing of the lock is usually provided with a handle slot. When the lock is locked, the handle is buckled into the handle slot. When unlocking, the handle is unlocked and the cabinet door is opened by operating the handle. In order to facilitate the opening action of the handle, the handle is usually equipped with a structure related to the automatic pop-up function, so that the handle automatically pops out of the handle slot after being unlocked. Usually, a torsion spring is designed at the handle pivot axis position to drive the handle to rotate and pop out. However, for some locks, the handle pops out only by relying on the torsion spring, and the pop-up response of the handle is not good, which has the defect of insufficient reliability. Summary of the invention

[0003] The purpose of the utility model invention is to overcome the defects of the prior art. The utility model provides a spring-pushing mechanism for a motorhome lock which is arranged in a handle groove and pushes the handle and has a reasonable and compact structure.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A pop-up mechanism for a motor home lock comprises a lock shell with a handle groove, and is characterized in that: a pop-up positioning seat is formed in the handle groove of the lock shell, a pop-up positioning seat is provided with a pop-up member and a pop-up spring, the pop-up member is configured to be limited to slide on the pop-up positioning seat along the depth direction of the handle groove, the pop-up member comprises a pop-up block arranged along the width direction of the handle groove, the pop-up block comprises push portions at both ends and a middle section connecting the two push portions, the middle section of the pop-up block is retracted relative to the push portion in the length direction of the handle groove to form a space avoidance recess.

[0006] Preferably, an elastic clamping foot is provided on the ejector block, and an anti-dropping clamping groove extending along the depth direction of the handle groove is opened on the handle groove wall, and one end of the anti-dropping clamping groove has a stop portion that cooperates with the elastic clamping foot. The elastic clamping foot can be elastically deformed under the action of external force to pass over the stop portion. As the ejector block is inserted into the ejector positioning seat, the elastic clamping foot elastically deforms to enter the anti-dropping clamping groove, and the elastic clamping foot cooperates with the stop portion to limit the ejector member on the ejector positioning seat.

[0007] Preferably, the middle section is provided with a positioning guide hole, the spring top positioning seat includes a positioning column corresponding to the positioning guide hole, and the positioning guide hole of the middle section is sleeved on the positioning column.

[0008] Preferably, the spring-loaded spring is arranged on the pushing portion, and the bottoms of the pushing portions at both ends are abutted against the spring-loaded spring.

[0009] Preferably, the pushing portion is formed with a spring insertion sleeve, and a spring positioning protrusion is provided on the bottom of the handle groove, the spring positioning protrusion can be inserted into the spring insertion sleeve, one end of the spring-top spring is inserted into the spring insertion sleeve, and the other end of the spring-top spring is sleeved on the spring positioning protrusion.

[0010] Preferably, the spring-pushing positioning seat includes a limit stopper, both side walls in the width direction of the handle groove are connected to the limit stopper, the limit stopper and the wall of the handle groove form an accommodating cavity, and the push portion is placed in the accommodating cavity.

[0011] By adopting the above technical scheme, when the handle is buckled into the handle groove, the handle contacts the spring-loaded piece, and the spring-loaded piece compresses the spring-loaded spring and stores energy. After the handle is unlocked, the spring-loaded spring pushes the spring-loaded piece to push the handle, driving the handle to pop out of the handle groove, thereby improving the response speed of the handle popping out; in addition, the spring-loaded block adopts the pushing parts on both sides along the width direction of the handle groove to contact the handle to realize the spring-pushing of the handle, and the pop-up action of the handle is stable and reliable. The avoidance recess can avoid the corresponding part of the handle and ensure the contact reliability between the spring-loaded top and the handle. Therefore, the structure of the spring-loaded block has the advantages of compact structure and reliable spring-pushing action of the handle; the spring-loaded spring is directly arranged under the pushing part in contact with the handle to realize a more reasonable arrangement, which is not only conducive to the installation arrangement of the spring-loaded spring, but also the spring force directly acts on the pushing part to ensure reliable spring-pushing.
