Description

Technical Field

[0001] The utility model relates to the field of intelligent door locks, and in particular to an internal protection device for an intelligent door lock handle. Background Art

[0002] With the widespread adoption of smart homes, smart door locks have become a crucial component of home security systems. Smart door locks not only enable unlocking via passwords, fingerprints, and mobile phones, but also offer remote control, alarms, and other functions, significantly improving the safety and convenience of living environments. However, the durability and service life of the door handle and its associated components are crucial factors affecting the overall performance of smart door locks.

[0003] Traditional smart door locks usually use internal fixings to fix the handle shaft to ensure the normal rotation and operation of the handle. However, this structure has some shortcomings. First, the single internal fixing method makes the fixing strength of the handle shaft low, which is prone to loosening or shaking during long-term use, thereby affecting the normal use of the smart door lock. Secondly, due to the lack of external protection measures, the handle shaft is easily impacted by external forces during use, resulting in damage or deformation, thereby shortening the service life of the door lock. In addition, in the prior art, since only internal fixings are used and there is a lack of additional vibration absorption measures, the smart door lock is easily affected by vibration and impact during use, which further reduces the stability of the handle shaft. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides an internal protection device for a smart door lock handle to improve the service life and stability of the handle shaft, prevent loosening, shaking or damage caused by long-term use or external force, and thus improve the overall reliability of the smart door lock.

[0007] an internal fixing member, the internal fixing member being fixedly mounted in the assembly cavity and used to fix the handle shaft, the internal fixing member being fixedly assembled with the housing;

[0008] An outer protective member is installed outside the inner fixing member, and the handle shaft passes through the outer protective member.

[0009] As a preferred technical solution, corner openings are formed at the four corner positions of the outer protective member, and a fixed leg is extended inwardly at each corner opening position, and the fixed leg is fixed to the inner fixing member.

[0010] As a preferred technical solution, a recessed step mounting position is provided at each of the four corners of the internal fixing member, the fixing bracket is installed in the step mounting position, and the fixing legs are fixedly connected to the step mounting position by screws.

[0011] As a preferred technical solution, the fixed legs are all elastic and L-shaped.

[0012] As a preferred technical solution, the four surfaces of the outer protective member are bent inwardly to form a covering protection cavity for covering the inner fixing member.

[0013] As a preferred technical solution, the outer protective member is made of metal material, an axial hole is provided in the middle of the outer protective member, and the handle shaft passes through the axial hole.

[0014] The beneficial effects of the utility model are as follows: the utility model provides an internal protection device for an intelligent door lock handle, which effectively improves the fixing strength and service life of the handle shaft by using a dual protection of an internal fixing member and an external protection member in the fixing structure of the handle shaft;

[0015] The elastic fixing feet set at the four corners of the outer protective part make the outer protective part have a certain elastic deformation ability after installation, which can effectively absorb vibration and impact during use, further improving the stability of the handle shaft and preventing it from loosening or shaking during long-term use;

[0016] In addition, the outer protective part is made of metal material, which provides stronger pressure and impact resistance, forming all-round coverage protection for the handle shaft, thereby significantly improving the overall durability and reliability of the smart door lock.

[0023] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0024] like Figure 1 and Figure 2 As shown, the utility model is a smart door lock handle inner protection device, comprising a housing 1, wherein the housing 1 has an assembly cavity 2, wherein the assembly cavity 2 is used to install a handle shaft 3 and other door lock components;

[0025] It also includes an internal fixing member 4, which is fixedly installed in the assembly cavity 2 and is used to fix the handle shaft 3. The internal fixing member 4 is fixedly assembled with the housing 1, and the handle shaft 3 is positioned and fixed once by the internal fixing member 4;

[0026] It also includes an outer protective part 6, which is installed on the outside of the inner fixing part 4. The handle shaft 3 passes through the outer protective part 6. The inner fixing part 4 and the outer protective part 6 are used to provide doubly protected handle shaft 3. The outer protective part 6 is used to protect the inner fixing part 4 and the handle shaft 3. In this way, stability is further improved to prevent damage and loosening of the handle shaft 3.
