Technical Field

[0001] This utility model relates to the field of handle technology, and in particular to a handle with variable length. Background Technology

[0002] Handles are commonly used in building decoration and furniture making to open and close doors, windows, drawers, and other components. They are mostly made of materials such as aluminum alloy, copper, stainless steel, plexiglass, and plastic, and are used to install on doors or drawers to facilitate opening and closing.

[0003] A search revealed that the Chinese patent "An Adjustable Handle" (publication number CN221823560U) includes a handle, a limiting slider, a door body, a connecting shell, and a connecting block. The handle has an extension rod slidably connected internally, with a support block welded to the top of the extension rod. One end of the handle is rotatably connected to a lead screw via a bearing, and a turntable is welded to the top of the lead screw above the handle. Limiting sliders are welded to both the front and rear ends of the extension rod. A door body is located behind the handle. An adjustment mechanism is provided; rotating the turntable rotates the lead screw, causing it to move the support block downwards, which in turn moves the extension rod downwards, thus adjusting the handle length. However, this method has the following drawbacks in practical use: adjustment requires continuous rotation of the turntable, resulting in low efficiency; and after prolonged use, the lead screw connection is prone to loosening due to vibration and wear. Furthermore, while the handle length can be adjusted initially, it becomes difficult to adjust after installation, making it unsuitable for users with different needs. Utility Model Content

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0028] The following is combined with Figures 1-5 This invention describes a variable-length handle.

[0029] In one embodiment, a variable-length handle includes a handle body 100 and an extension rod 200 disposed therein; it also includes an adjustment mechanism 300 disposed inside the handle body 100 and used to adjust and lock the vertical position of the extension rod 200; wherein, the adjustment mechanism 300 includes a piston plate 310, a closing plate 320 and a trapezoidal groove 330, the trapezoidal groove 330 is opened into the interior of the handle body 100, the closing plate 320 is disposed inside the trapezoidal groove 330, one side of the piston plate 310 is connected to one end of the extension rod 200, and the outer side of the piston plate 310 is slidably connected to the interior of the handle body 100.

[0030] like Figure 2 and Figure 3 As shown, a groove is provided at one end of the handle body 100 and on the inner wall, and the groove is connected to the trapezoidal groove 330; a set of springs 331 are installed inside the trapezoidal groove 330, and one end of the springs 331 is installed to one side of the closing plate 320.

[0031] In this embodiment, when adjusting the length of the handle body 100, the user can directly pull the extension rod 200 to make the piston plate 310 move accordingly. During this process, the gas inside the handle body 100 interacts with the outside through the groove and trapezoidal groove 330. After the adjustment is in place, the spring 331 abuts against the closing plate 320 to seal the trapezoidal groove 330 and perform air-tightening treatment, thereby completing the fixed locking of the piston plate 310 and the extension rod 200 to ensure stability.

[0032] It should be noted that the multi-point spring 331 used in this application applies pressure to the closing plate 320. The supporting force of the spring 331 can overcome the weight of the piston plate 310 and the extension rod 200, ensuring the stability of the closing plate 320. The specific specifications of the spring 331 can be selected according to the actual usage requirements.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a button 110 is slidably connected inside a groove, and one side of the button 110 is mounted to the outside of the closing plate 320.

[0034] When adjusting the length, the user can press button 110 in advance to make the closing plate 320 move accordingly, forming an air guide channel between its outer side and the trapezoidal groove 330.

[0035] like Figure 3 and Figure 4 As shown, a sealing ring is embedded on one side of the closing plate 320, and the outer side of the sealing ring contacts the trapezoidal groove 330.

[0036] The sealing ring is fitted with the trapezoidal groove 330 to improve the airtightness and reduce gas leakage, thereby ensuring the stability of the extension rod 200.

[0037] like Figure 3 and Figure 4 As shown, a limiting rod is provided inside the trapezoidal groove 330, which penetrates the closing plate 320. The spring 331 is sleeved on the outside of the limiting rod, and the connection between the limiting rod and the closing plate 320 is sealed.

[0038] The closing plate 320 is limited by a limiting rod to reduce accidental displacement during movement. At the same time, the sealing treatment reduces the flow and leakage of gas at the connection between the two.

[0039] like Figure 1 and Figure 5 As shown, both the handle body 100 and the extension rod 200 are provided with support columns on their outer sides. One end of each support column is provided with a mounting plate, and one end of one of the support columns is slidably connected to the interior of the adjacent mounting plate.

[0040] The mounting plate is attached to the door or window to be connected, and then bolts are used to complete the connection. When the handle body 100 is adjusted in length, the bottom support will slide on the bottom mounting plate accordingly, without affecting the length adjustment operation.

[0041] Working principle: When adjusting the length of the handle body 100, the user can press the button 110 with one hand to separate the sealing ring on the closing plate 320 from the trapezoidal groove 330. Then, the user can directly pull the extension rod 200 to the preset position with the other hand. Then, the user can release the button 110. At this time, the spring 331 drives the closing plate 320 to reset, completing the airlock and making the extension rod 200 stable, thus completing the entire adjustment operation.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
