Description

Technical Field

[0001] The utility model relates to the technical field of handles, in particular to a handle with a telescopic function. Background Art

[0002] Handle, also refers to pull handle, handshake; the place on an object to hold the hand; mechanical accessories, through which mechanical equipment and cabinet equipment (mostly on doors) can be held, operated or moved, and metal handles such as handles and handrails that are convenient for door opening. The handles have two installation methods: type A internal thread hole and type B external thread. Type A metal embedding is made of brass embedding, and type B bolts are made of ordinary steel plated with blue and white zinc. Pre-embedded inserts of different materials can also be customized according to different customer needs.

[0003] In the process of using the handle, it is usually necessary to press the handle to open the door, but some people have less strength, and it is necessary to retract the handle to make it longer for people with less strength to use. For example, the application number: CN202223431354.0 discloses a handle with a telescopic function. The above utility model installs its telescopic rod on the limit slider, and then moves the limit slider to lengthen the telescopic rod, which is convenient for people with less strength to use. However, the limit slider of the above utility model only adopts a damping layer for damping, and is installed through the friction generated by the damping layer and the limit slider. This requires a lot of strength during the movement, which is more difficult to use. At the same time, after the movement is completed, the limit slider cannot be positioned and installed, which results in poor stability of the limit slider, which may cause the limit slider to move back and forth easily. When the limit slider moves back and forth, it is also easy to cause the user's hand to be pinched, which is not conducive to the use of the handle. Utility Model Content
