Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example 1

Referring to fig. 1-3, an anti-disassembly handle structure comprises a handle shell 1 and a handle cover 2, wherein the handle shell 1 is hollowed out, studs 3 with threaded holes are fixedly installed on the inner wall of the bottom of the handle shell 1, the studs 3 are symmetrically arranged, screws 4 with pads matched with the studs 3 are arranged on the studs 3, buckles 5 integrally formed with the inner wall of the bottom of the handle cover 2 are fixedly installed on the inner wall of the bottom of the handle cover 2, and the buckles 5 correspond to the studs 3 one to one; through the mutual matching of the buckle 5 and the screw 4 with the pad, when the assembly is carried out, the screw 4 with the pad is screwed into the stud 3, then the handle cover 2 is arranged in the handle shell 1, because the buckle 5 which is integrally formed with the inner wall of the bottom of the handle cover 2 is fixedly arranged on the inner wall of the bottom of the handle cover 2, through the mutual matching of the buckle 5 and the screw 4 with the pad, the buckle 5 is clamped below the gasket of the screw 4 with the pad which is screwed into the stud 3, at the moment, the handle cover 2 is firmly assembled with the handle shell 1, so that the assembly of the handle shell 1 and the handle cover 2 is realized, the disassembly by using a tool technology is avoided, meanwhile, the surface of the handle shell is ensured to have no screw hole, and the attractiveness of the appearance is kept; the handle shell 1 is hollowed out to effectively save manufacturing materials; further, in order to ensure the clamping stability of the buckle 5 and the gasket with the cushion screw 4, the buckle 5 is designed to be an arc surface; and furthermore, in order to improve the fluency when the buckle 5 is clamped with the gasket with the cushion screw 4, chamfering treatment is carried out on the corresponding surface of the top part contacted by the buckle 5 and the gasket with the cushion screw 4.

The material of the handle shell 1 is not limited, and in this embodiment, preferably, the material of the handle shell 1 is a metal material.

The material of the handle cover 2 is not limited, and in this embodiment, preferably, the material of the handle cover 2 is a plastic material.

The specification of the screw 4 is not limited, for example, a socket head cap screw, in this embodiment, it is preferable that the screw 4 is a cross screw.

The size of the screw 4 is not limited, and in this embodiment, preferably, the size of the screw 4 is M3 × 6.

The working principle of the embodiment is as follows: through the mutual matching of the buckle 5 and the screw 4 with the pad, when the assembly is carried out, the screw 4 with the pad is screwed into the stud 3, then the handle cover 2 is arranged in the handle shell 1, because the buckle 5 which is integrally formed with the inner wall of the bottom of the handle cover 2 is fixedly arranged on the inner wall of the bottom of the handle cover 2, through the mutual matching of the buckle 5 and the screw 4 with the pad, the buckle 5 is clamped below the gasket of the screw 4 with the pad which is screwed into the stud 3, at the moment, the handle cover 2 is firmly assembled with the handle shell 1, so that the assembly of the handle shell 1 and the handle cover 2 is realized, the disassembly by using a tool technology is avoided, meanwhile, the surface of the handle shell is ensured to have no screw hole, and the attractiveness of the appearance is kept; and the hollow-out arrangement in the handle shell 1 effectively saves the manufacturing material.

Example 2

A fingerprint handle comprises the anti-dismantling handle structure as described in embodiment 1, and due to the adoption of the anti-dismantling handle structure, a fingerprint module 6 is fixedly installed between the handle shell 1 and the handle cover 2 of the anti-dismantling handle structure, so that the fingerprint handle has the function of preventing dismantling and can keep the aesthetic property of the fingerprint handle.
