Description

Technical Field

[0001] This utility model relates to a lock, and more specifically, to a decorative cover for a lock. Background Technology

[0002] Currently, there are various types of door locks on the market. Among them, decorative lock covers installed in pairs on the inner and outer sides of the door are very common. Generally, the structure of a decorative lock cover includes a cover, a fixing plate, and the fixing plate being positioned and fitted inside the cover, thus enhancing the product's aesthetics. Existing decorative lock covers are generally made of stamped metal. During installation, a screw is screwed onto the fixing plate at the bottom. This type of metal cover has high production costs, and because it is stamped, its shape is relatively fixed, failing to meet the diverse choices of current customers. Furthermore, the screw-fixed installation method requires tools, making installation complex, and the screws themselves are also expensive. Therefore, an improvement is urgently needed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a decorative cover for locks. The decorative cover is made of plastic material and is integrally injection molded, which has the advantages of low production cost and easy installation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a decorative cover for a lock, comprising a decorative cover and a fixing plate, wherein the decorative cover has a recessed cavity, the fixing plate is disposed within the recessed cavity, two protrusions are provided on the side wall of the recessed cavity of the decorative cover at a gap, and a circular protrusion located below the two protrusions is provided on the side wall of the fixing plate, a locking block is provided on the other side of the recessed cavity opposite to the two protrusions, and a locking groove is provided on the fixing plate to engage with the locking block, wherein the decorative cover, the two protrusions and the locking block are integrally injection molded by injection molding.

[0005] The present invention is further configured such that: the card block is vertically fixed at the bottom of the cavity, the fixing plate is provided with an inwardly recessed relief portion relative to the card block, and the card groove is provided in the relief portion; when the fixing plate is installed in the cavity of the decorative cover, the end of the card block can be fixed in the card groove.

[0006] The present invention is further configured such that: the end of the card block is provided with a rounded corner on the side near the cavity.

[0007] The present invention is further configured such that a connecting block is provided between the card block and the side wall of the cavity.

[0008] The present invention is further configured such that the appearance of the decorative cover can be injection molded into different shapes by injection molding process.

[0009] By adopting the above technical solution, this practical lock decorative cover is integrally injection molded from plastic material, which results in low overall production cost and allows for injection molding of different shapes to meet diverse customer choices. At the same time, it does not require tools for installation, making it quick and convenient to install. Attached Figure Description

[0014] Reference Figures 1 to 3 The embodiments of this utility model will be further described below.

[0015] This utility model discloses a decorative cover for a lock, including a decorative cover 1 and a fixing plate 2. The decorative cover 1 has a cavity 10, and the fixing plate 2 is disposed in the cavity 10. Two protrusions 11 are provided on the side wall of the cavity 10 of the decorative cover 1, which are spaced apart. A circular protrusion 20 is provided on the side wall of the fixing plate 2, located below the two protrusions 11. A locking block 3 is provided on the other side of the cavity 10 opposite to the two protrusions 11. The fixing plate 2 is provided with a locking groove 21 that engages with the locking block 3. The decorative cover 1, the two protrusions 11, and the locking block 3 are integrally injection molded. The locking block 3 is vertically fixed at the bottom of the cavity 10. The fixing plate 2 has an inwardly recessed relief portion 22 relative to the locking block 3. The locking groove 21 is disposed in the relief portion 22. When the fixing plate 2 is installed in the cavity 10 of the decorative cover 1, the end of the locking block 3 can be locked in the locking groove 21 for fixation. The end of the locking block 3 near the cavity 10 has a rounded corner 30. A connecting block 31 is provided between the locking block 3 and the side wall of the cavity 10. The appearance of the decorative cover 1 can be injection molded into different shapes.

[0016] Working principle: When installing the decorative cover 1, simply hold the decorative cover 1 and align one end of the clip 3 with the recessed part 22 of the fixing plate 2 to snap it on. Figure 2As shown, when the decorative cover 1 is fastened onto the fixed plate 2, the locking block 3 inside the decorative cover 1 will engage with the slot 21 of the fixed plate 2 for fixation. Simultaneously, the two protrusions 11 will slide past the round protrusion 20 and engage below it to limit and fix the decorative cover 1. Thus, the decorative cover 1 can be conveniently and quickly installed onto the fixed plate 2 via the locking block 3 and the two protrusions 11. By providing a rounded corner 30 on the side of the locking block 3 near the recess 10, the locking block 3 can deform under force when the decorative cover 1 is fastened onto the fixed plate 2, facilitating the installation of the decorative cover 1 onto the fixed plate 2. By providing a connecting block 31 between the locking block 3 and the side wall of the recess 10, the locking block 3 has better stability and is less prone to damage under force.

[0017] This practical lock decorative cover 1 is made of plastic material through one-piece injection molding, which makes its overall production cost low. It can be injection molded into different shapes to meet the diverse choices of customers. At the same time, no tools are required for installation, making it quick and convenient to install.

[0018] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
