Technical Field

[0001] The utility model belongs to the technical field of intelligent door lock handles, and specifically refers to a handle structure with low cost and convenient assembly. Background Art

[0002] Smart door lock is a lock that combines electronic technology, mechanical technology and network technology. It has the characteristics of intelligence, convenience and security. The handle is the basic component of the smart door lock. The door lock can be opened and closed by the handle. The push-pull handles of conventional smart door locks are made of metal. The fingerprint module and radar module are fixed with screws and blocks. There are many parts, many processes and many working hours during assembly, and the product cost and assembly cost are relatively high. Therefore, we propose a low-cost and easy-to-assemble handle structure to solve the above problems. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a low-cost and easy-to-assemble handle structure, which effectively solves the problem of high cost and assembly fee caused by many parts, many processes and many working hours during the assembly of the existing smart door lock handle structure.

[0004] The technical solution adopted by the utility model is as follows: The utility model proposes a low-cost and easy-to-assemble handle structure, including a plastic handle and a plastic cover plate, the plastic cover plate is pluggably connected to the plastic handle, the plastic cover plate is threadedly connected with a cover plate fixing screw, and the cover plate fixing screw passes through the plastic handle, the plastic handle is provided with a through hole, and the inner wall of the through hole is provided with an undercut A, a fingerprint module is pluggably connected to the undercut A, an iron handle plate is pluggably connected to the plastic handle, and the iron handle plate is arranged above the fingerprint module, a plastic sealing plate is provided on the upper end of the iron handle plate, and the plastic sealing plate is connected to the plastic handle through a sealing plate screw, an undercut B is fixed on the inner side of the plastic handle, and a radar module is pluggably connected to the undercut B.

[0005] As an improvement of the present solution, the plastic handle is arranged between the plastic cover plate and the iron handle plate, the radar module is arranged between the plastic handle and the iron handle plate, the iron handle plate is arranged between the plastic handle and the plastic sealing plate, and the plastic cover plate is provided with a circular through hole which is coaxially arranged with the through hole on the plastic handle.

[0006] As an improvement of the present solution, the sealing plate screws sequentially penetrate the plastic sealing plate and the iron handle plate and are threadedly connected to the plastic handle, and a plurality of groups of studs are provided in the plastic handle for connection with the sealing plate screws.

[0007] As an improvement of the present solution, the plastic cover is provided with a plurality of buckles, and the plastic handle is provided with a plurality of rectangular through holes for connecting with the buckles on the plastic cover.

[0008] As an improvement of the present solution, the plastic cover plate and the plastic handle are both made of plastic material, and the iron handle plate is made of bent iron plate.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows:

[0010] In this structure, the three undercuts at A of the plastic handle allow the fingerprint module to be easily buckled in and fixed; the undercuts on both sides at B allow the radar module to be easily buckled in and fixed, which is impossible to achieve on metal handles. At the same time, the material cost and electroplating cost of the plastic handle are significantly reduced. An iron handle plate is added to the handle to ensure that the strength of the handle is not reduced. The overall assembly eliminates the assembly of pressure blocks and screws, saving labor and time, which can reduce the cost of smart lock products and increase market competitiveness.
