[0032] like Figures 1 to 8 As shown, a telescopic damping handle includes a handle body 1, a center column 11 is provided on the handle body 1, a rack 2 is provided in the center column 11, an outer cover 3 fixed to the cabinet door is provided on the outer cover 3, an elastic member 4 is provided between the handle body 1 and the outer cover 3, a base block 5 is fixed on the outer cover 3, and a gear 6 meshing with the rack 2 is assembled on the base block 5; a telescopic mechanism is provided between the rack 2 and the base block 5, and the telescopic mechanism includes a positioning groove 21 provided on the rack 2 and a positioning rod 7 provided on the base block 5, the positioning groove 21 is provided with an extension groove 21a and a retraction groove 21b, and the positioning rod 7 can be slidably assembled in the positioning groove 21.

[0033] The elastic member 4 is preferably a spring.

[0034] The positioning groove 21 includes an annular portion and a straight portion that are connected to each other. The extending groove 21a is provided at the inner end of the straight portion, and the retracting groove 21b is provided at the outer end of the annular portion.

[0035] The straight portion and the annular portion are eccentrically arranged, and a guide portion 21c is arranged between the annular portion and the straight portion.

[0036] The rack 2 is provided with toothed portions 2a on both sides, and the base block 5 is equipped with two gears 6 meshing with the corresponding toothed portions 2a.

[0037] In this embodiment, two gears 6 are symmetrically arranged on the base block 5, and the gears 6 extend into the center column 11. The symmetrical arrangement of the two gears 6 ensures uniform force on both sides of the rack 2, which helps improve the stability of the handle's extension and retraction. After assembly, the gears 6 extend into the center column 11, making the structure more compact.

[0038] The center column 11 forms a plane on the rack side and a cylindrical surface on the opposite side of the rack.

[0039] The positioning rod 7 includes an assembly ring 71 and a rod-shaped portion 72 . The assembly ring 71 is rotatably engaged with the base block 5 .

[0040] The rod-shaped portion 72 is L-shaped.

[0041] The handle body 1 is provided with a housing 8. When the handle body 1 is retracted, the outer surface of the handle body 1 is flush with the outer surface of the housing 8. The provision of the housing 8 facilitates the installation of the telescopic handle. The telescopic handle is integrally mounted on the cabinet door through the housing 8.

[0042] The outer periphery of the handle body 1 is provided with anti-slip grooves 1a. The provision of the anti-slip grooves 1a can increase the surface friction and facilitate the application of force when the cabinet door is opened.

[0043] In this embodiment, the handle body 1 is a circular structure. The handle body 1 can also be a square structure, a rectangular structure, or a diamond structure.

[0044] Working principle:

[0045] The telescopic damping handle of the present invention is provided with a center column 11 on the handle body 1. The extension and retraction of the handle is achieved through the sliding cooperation between the center column 11 and the outer cover 3. In its sliding structure, the outer cover 3 can play a positioning and guiding role for the center column 11, and the direct sliding cooperation between the center column 11 and the outer cover 3 can increase the diameter of the center column 11, improve the assembly strength, and improve the stability of the extension and retraction.

[0046] In addition, a rack 2 is provided in the center column 11, and toothed portions 2a are provided on both sides of the rack 2. The toothed portions 2a are engaged with the gear 6 on the base block 5 to form a damping sliding structure, which can slow down the extension and retraction speed of the handle, avoid the handle moving too fast and causing impact damage, and improve the service life of the handle.

[0047] In the telescopic mechanism, the switching between the extended and retracted states is achieved through the cooperation of the positioning rod 7 and the positioning slot 21. As shown in Figure 1, the handle body 1 is in the extended state, at which time the positioning rod 7 is located in the extended position slot 21a of the positioning slot 21. When the handle body 1 needs to be retracted, the handle body 1 is pressed inward, causing it to move inward against the elastic force of the elastic member 4. As the handle body 1 moves inward, the positioning rod 7 moves along the positioning slot 21 until it enters the retracted position slot 21b, locking the positioning rod 7 and the handle body 1 into the retracted state.

[0048] As shown in Figure 8, the handle body 1 is in a retracted state. At this time, the positioning rod 7 is located in the retracted slot 21b of the positioning slot 21. When the handle body 1 needs to be extended, the handle body 1 is continuously pressed inward, so that the positioning rod 7 moves along the positioning slot 21 and returns to the extended slot 21a of the positioning slot 21. During this process, the handle body 1 moves inward a short distance and then moves outward under the elastic force of the elastic member 4. The handle body 1 extends outward and enters the extended state.

[0049] The above are only preferred embodiments of the present invention and do not limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
