[0029] Reference Figures 1 to 6 In one embodiment of the utility model, a lock cover connection structure is used to connect to a lock body, including:

[0030] Cover plate 100;

[0031] A plurality of contact parts 200 are arranged on the back side of the cover plate 100 and are arranged at intervals in the length direction of the cover plate 100, wherein the contact part 200 includes at least one connecting contact 210, wherein when the contact part 200 includes a plurality of connecting contacts 210, the plurality of connecting contacts 210 are arranged at intervals in the width direction of the cover plate 100;

[0032] The connection contacts 210 and the cover plate 100 are connected to each other, and the connection contacts 210 are made of polymer material.

[0033] In the prior art, the lock cover is mostly bonded, which is inconvenient to disassemble and also has the risk of aging; if the lock cover and the lock body are directly connected by snap-fitting, then the lock cover and the lock body need to have a connecting structure respectively, and the above connecting structure has the problem of difficult molding.

[0034] In the present invention, the cover plate 100 is the main structure. A plurality of contact parts 200 are arranged on the back of the cover plate 100 and are arranged at intervals in the length direction of the cover plate 100. The arrangement of the contact part 200 is determined by the final fixing effect and the convenience of processing. The contact part 200 includes at least one connecting contact 210. When the contact part 200 includes a plurality of connecting contacts 210, the plurality of connecting contacts 210 are arranged at intervals in the width direction of the cover plate 100. The number and position of the connecting contacts 210 should also be determined by the final fixing effect and the convenience of processing. The connecting contact 210 and the cover plate 100 are a connecting structure, and the connecting contact 210 is made of a polymer material. By setting the connecting contact 210 as a connecting structure, the processing difficulty of the cover plate 100 is reduced. The connecting contact 210 is processed separately to reduce the processing difficulty of the cover plate 100, and the materials of the connecting contact 210 and the cover plate 100 can also be independent, thereby forming greater flexibility of use. Specifically, the material of the connecting contact 210 can be various types of plastic or rubber.

[0035] In summary, the connection method of the cover plate 100 is adjusted from bonding to snap connection; at the same time, a connection structure is set between the connection contact 210 and the cover plate 100 to reduce the processing difficulty of the cover plate 100, and at the same time, the materials of the connection contact 210 and the cover plate 100 can be independent, thereby forming greater flexibility in use.

[0047] In this embodiment, a preferred arrangement of the connection contacts 210 is provided, which has the advantages of stable fixation and easy disassembly.

[0048] In one embodiment, the connecting contact 210 is made of PVC, PMMA or PP.

[0049] In this embodiment, the strength and weather resistance are achieved by limiting the material properties of the connection contacts 210 , and common materials are selected, such as PVC (polyvinyl chloride), PMMA (polymethyl methacrylate) or PP (polypropylene) with relatively mature processing technology.

[0050] In one embodiment, the cover plate 100 is made of polymer material, aluminum alloy or stainless steel.

[0051] In this embodiment, considering that in some scenarios, the cover plate 100 needs to be made of metal, and the cover plate 100 and the connecting contacts 210 are separate structures, the material requirements of the cover plate 100 can be met.

[0052] The utility model also provides a handle lock, comprising the lock cover connecting structure mentioned above.

[0053] In this embodiment, the above locking cover connection structure improves the connection convenience of the cover plate 100 and the strength of the connection structure compared to the existing gluing method.

[0054] In summary, the lock cover connection structure and handle lock provided by the utility model adjust the connection method of the cover plate from bonding to snap connection; at the same time, a connection structure is set between the connecting contact and the cover plate to reduce the difficulty of processing the cover plate, and at the same time, the materials of the connecting contact and the cover plate can be independent, thereby forming greater flexibility in use.
