Description

Technical Field

[0001] This utility model relates to the field of door and window components, specifically to a handle with an adjustable square shaft length. Background Technology

[0002] A handle is an important component on doors and windows used to control the opening and closing of locks. It consists of a housing and a square shaft that passes through a square hole. The housing is installed on the door or window frame, and the square shaft passes through the housing. One end of the shaft extends out of the housing and connects to the handle, while the other end extends into the cavity of the door frame and connects to the latch mechanism. By rotating the handle, the square shaft rotates, which in turn drives the latch mechanism, thereby opening or closing the door or window.

[0003] Existing handles all have square shafts that are directly pressed into the handle, and the extension length is fixed. The extension length of the square shaft cannot be adjusted according to the thickness of the door and window profiles in the actual application. This means that users not only need to measure the thickness of the door and window profiles and buy handles with square shafts of the corresponding extension length when purchasing handles, but also require merchants to stock up on a large number of different specifications, which is very inconvenient. Utility Model Content

[0004] Based on this, and in view of the prior art, this utility model provides a handle with an adjustable square shaft length.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An adjustable square shaft handle includes a handle base mounted on a frame profile, a handle mounted on the handle base and capable of rotation, and a square shaft. The handle base has a cavity inside, and an opening is formed on the panel of the handle base. The handle has a mating surface that mates with the handle base and an insertion part that protrudes from the mating surface. The insertion part is inserted into the cavity through the opening. The handle has a square hole inside that matches the shape of the shaft. This square hole is a blind hole. The shaft is installed in the square hole, with its outer end extending out of the square hole. A rod is formed on the inner end face of the shaft. A spring is also provided in the square hole.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 4 As shown, this utility model is an adjustable square shaft handle, installed on the frame profile 9, including a handle 10, a handle base 11, and a square pivot 8. The handle base 11 is installed on the frame profile 9.

[0023] Among them, such as Figure 1 and Figure 2 As shown, the handle base 11 has a cavity 111 inside. An opening 112 is formed on the panel of the handle base 11. A first sleeve 12 and a second sleeve 13 fitted onto the first sleeve 12 are disposed within the cavity 111. A first step 121 is formed on the lower outer circumferential surface of the first sleeve 12. The lower end face of the second sleeve 13 abuts against the upper end face of the first step 121, and its upper end extends upwards through the opening 112. In this embodiment, both the handle base 11 and the second sleeve 13 are made of POM. POM material has elasticity and good wear resistance.

[0024] like Figure 2 As shown, the handle 10 is mounted on the handle base 11 and is rotatable. The handle 10 has a mating surface 101 that mates with the handle base and an insertion portion 102 that protrudes from the mating surface 101. The mating surface 101 has a groove 103. A second step 104 is provided at the root of the insertion portion 102. A plastic gasket 16 is provided between the mating surface 101 and the panel of the handle base 11. The gasket reduces friction between the handle and the handle base. During assembly, the insertion portion 102 of the handle 10 is inserted into the second sleeve 13, which extends into the first sleeve 12. The upper end of the second sleeve 13 is inserted into the groove 103, and the upper end face of the first sleeve 12 abuts against the lower end face of the second step 104. The edge 1021 of the insertion portion 102 is riveted to the edge 122 of the first sleeve 12 to prevent the handle from falling off. When the handle 10 rotates, it will drive the first sleeve 12 to rotate synchronously.

[0025] In this embodiment, the first sleeve 12 and the handle 10 are made of zinc alloy. Zinc alloy has high strength and hardness, is wear-resistant, and is not easily deformed.

[0026] Elastic elements 14 are installed on the left and right sides of the first sleeve 12 within the cavity 111. Each elastic element 14 has two opposing protrusions 141. Four positioning grooves 142 are evenly distributed on the circumferential surface of the first sleeve 12. The two protrusions 141 are engaged within the two opposing positioning grooves 142. When the handle is rotated, the protrusions 141 disengage from the positioning grooves 142. During rotation, the protrusions 141 press against the outer wall of the first sleeve, causing the spring plates 143 of the elastic elements 14 to shift outwards, generating elastic force. When rotating to the next positioning groove, the protrusions 141 rebound under the action of elastic force, extending into the limiting groove to position the first sleeve.

[0027] Connectors 15 are installed on the left and right sides of the cavity 111. Two elastic elements 14 are fitted onto the corresponding connectors 15. A through hole 151 is opened in the connector 15. A bolt is provided in the through hole 151. During assembly, the end of the bolt passes through the through hole and is tightened on the panel of the frame profile to fix the handle base.

[0028] The handle 10 has a square hole 106 inside, which is adapted to the shape of the square pivot 8. The pivot 8 is installed in the square hole 106, with its outer end extending out of the square hole 106. A rod portion 108 is provided on the inner end face of the pivot 8. The square hole 106 is a blind hole. A spring 107 is also provided in the square hole 106. The spring 107 is sleeved on the rod portion 108, with one end abutting against the inner end face of the square hole 106 and the other end abutting against the inner end face of the pivot.

[0029] In summary, by setting a spring inside the square hole in this utility model, with the spring sleeved on the rod of the rotating shaft, one end abutting against the inner end face of the square hole and the other end abutting against the inner end face of the rotating shaft, the rotating shaft can be extended or retracted by pressing it according to the thickness of the profile in the actual application, thereby obtaining the required extension length of the rotating shaft, which is very convenient.
