Description

Technical Field

[0001] This application relates to the field of lock cover technology, and in particular to a lock cover structure for a lock. Background Technology

[0002] Currently, lock covers are mainly manufactured using a one-piece sheet metal forming process. However, the handle area of ​​this lock cover features a hollowed-out internal structure. Referring to existing application number: CN202321229467.4, Figure 1 , Figure 2 The lock cover structure is shown. When using a one-piece manufacturing method, the material corresponding to the hollowed-out area of ​​the grip needs to be cut off, and a layer of rubber needs to be injection molded over that location. This one-piece manufacturing method results in the material of the hollowed-out part of the grip being cut off and discarded, causing a material waste problem. Utility Model Content

[0003] To address the issue of material waste in lock cover manufacturing, this application provides a lock cover structure for a lock.

[0004] This application provides a lock cover structure for a lock, which adopts the following technical solution:

[0005] A lock cover structure includes a handle and a cover body, wherein the handle is bent into shape and detachably fixedly connected to the cover body.

[0006] By adopting the above technical solution, the traditional one-piece processing method has been changed, reducing the steps of cutting material in the hollow area of ​​the grip, effectively solving the problem of material waste, reducing production costs, and the detachable connection makes it convenient to replace or repair the grip or cover separately in the future.

[0007] Optionally, the handle includes a grip portion and two connecting portions extending from both ends of the grip portion to the same side. The ends of the two connecting portions are provided with riveting holes, and the connecting portions are riveted and fixed to the cover.

[0008] By adopting the above technical solution, this structure makes the connection between the handle and the cover more stable and reliable, and the riveting method is simple and easy to operate, which can ensure the stability of the overall structure of the lock cover.

[0009] Optionally, the middle of the two connecting portions is provided with a recessed portion that is recessed in the direction of approaching each other.

[0010] By adopting the above technical solution, on the one hand, when it is necessary to attach material at this position, the recess can increase the bonding area between the attached material and the grip, and improve the adhesion of the attached material; on the other hand, the design of the recess can change the stress distribution of the grip, so that the stress of the grip is more dispersed when it is under force, thereby improving the grip's resistance to deformation and extending its service life.

[0011] Optionally, the connecting portion is provided with an attachment hole, which is located at the recessed portion.

[0012] By adopting the above technical solution, when it is necessary to attach other materials (such as rubber, plastic, etc.) to the grip surface, the attachment holes can further increase the contact area and adhesion between the attachment material and the grip, so that the attachment material is more firmly fixed to the grip.

[0013] Optionally, the grip has a stamped rib in the middle, which covers the grip portion and the two connecting portions.

[0014] By adopting the above technical solutions, the ribs can significantly enhance the overall strength and rigidity of the grip, making it less prone to deformation or damage when subjected to external forces. At the same time, the stamping process ensures the integrity between the ribs and the grip, improving structural stability.

[0015] Optionally, the lower end of the gripping part is provided with a clearance opening.

[0016] By adopting the above technical solution, the clearance opening can provide space for the operator to lift, ensuring the normal use of the lock and improving the compatibility and practicality of the lock cover structure.

[0017] Optionally, an attachment groove is provided at the upper end of the connection between the gripping part and the connecting part.

[0018] By adopting the above technical solution, when it is necessary to attach material at this position, the attachment groove can increase the bonding area between the attachment material and the grip, improve the adhesion of the attachment material, and make the attachment material adhere more firmly to the grip.

[0019] In summary, this application includes at least one of the following beneficial effects:

[0020] 1. The handle is bent and detachably connected to the cover, which changes the traditional one-piece molding method, effectively solving the problem of material waste and reducing production costs;

[0021] 2. The stamped ribs in the middle of the grip cover the grip and connecting parts, which significantly enhances the overall strength and rigidity of the grip. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a lock cover structure for a lock. (Refer to...) Figure 1 , 2 The lock cover structure includes a handle 1 and a cover body 2, which are independent components. The handle 1 is made of metal strips, which are formed through a bending process to give it a specific shape and structure to meet the usage requirements of the lock. The bent handle 1 is fixedly connected to the cover body 2.

[0028] The handle 1 is manufactured by bending and forming and is processed separately from the cover 2, replacing the traditional one-piece locking and cover forming process. This bending and forming method does not require a large amount of material to be removed from the handle 1, which greatly reduces material waste.

[0029] Reference Figure 3 The handle 1 includes a grip part 3 and two connecting parts 4. The grip part 3 is the part held by the user. The two connecting parts 4 extend from both ends of the grip part 3 to the same side, forming a U-shaped structure. This structural design allows the handle 1 to be better connected and fixed to the cover 2.

[0030] Riveting holes 5 are provided at the ends of both connecting parts 4, and the connecting parts 4 and the cover 2 are fixedly connected by riveting. In specific operation, the riveting holes 5 at the ends of the connecting parts 4 are aligned with the corresponding holes on the cover 2, and then the rivets are passed through these holes. The rivets are riveted by riveting tools to cause plastic deformation of the rivets, thereby firmly connecting the connecting parts 4 and the cover 2 together.

[0031] Of course, in other embodiments, the connection between the connecting part 4 and the cover 2 can also be made in other ways, such as threaded connection, snap-fit ​​connection, or even welding.

[0032] Reference Figure 3 The two connecting parts 4 are provided with a recessed part 6 in the middle of the two connecting parts 4, which is recessed in the direction of approaching each other. The setting of the recessed part 6 increases the unevenness of the surface of the connecting part 4. When other materials, such as rubber layers, need to be attached to the surface of the connecting part 4, the contact area between the attached material and the connecting part 4 can be increased, thereby improving the adhesion of the attached material.

[0033] The connecting part 4 is also provided with an attachment hole 7, which is located at the position of the recess 6. When material is attached to the surface of the connecting part 4, some of the material will enter the attachment hole 7. After the material is cured, the material in the attachment hole 7 forms an "anchoring" structure with the connecting part 4, which further enhances the connection strength between the material and the connecting part 4, allowing the material to be more firmly attached to the connecting part 4.

[0034] The grip 1 has a stamped rib 8 in the middle, which covers the grip portion 3 and the two connecting portions 4. The rib 8 is made by stamping, which can form an integral structure with the grip 1, ensuring the firmness of the connection between the rib 8 and the grip 1. The rib 8 significantly enhances the overall strength and rigidity of the grip 1.

[0035] The lower end of the grip part 3 is provided with a clearance opening 9. In actual use of the lock, the operator will perform operations such as lifting, and the clearance opening 9 provides clearance space for the operator to lift.

[0036] An attachment groove 10 is provided at the upper end of the connection between the grip part 3 and the connecting part 4. The function of the attachment groove 10 is similar to that of the recessed part 6 and the attachment hole 7. When material is attached at the connection between the grip part 3 and the connecting part 4, the attachment groove 10 can increase the bonding area between the attached material and the grip 1, improve the adhesion of the attached material, and make the attached material adhere more firmly to the grip 1.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
