[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0027] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] In this embodiment, a rubber damping bushing expansion mechanism is proposed, see Figure 1-Figure 3 The rubber shock-absorbing bushing expansion mechanism includes a clamping claw with a through groove on the axis, and the clamping claw has three movable parts that approach or move away from the axis of the clamping claw.

[0030] There is also a second sliding block 7 which penetrates into the through slot and slidably cooperates with the movable part in the claw.

[0031] To further illustrate, the movable portion of the clamping claw extends toward the axis relative to the second slider 7, and the second slider 7 is slidably matched with the movable portion of the clamping claw. In addition, the movable range of the second slider 7 is limited to the through slot.

[0032] To further explain, the rubber piece encircles all the second sliders 7, and when the movable part in the claw moves away from the claw axis, the inner sleeve enters the encircling space formed by all the second sliders 7, and a person pulls all the second sliders 7, so that the rubber piece encircles the inner sleeve after all the second sliders 7 are detached.

[0033] It should be noted that the rubber shock-absorbing bushing mentioned in this embodiment includes an inner sleeve, a rubber part and an outer sleeve from the inside to the outside, and this embodiment focuses on the inner sleeve entering the rubber part.

[0034] See also Figure 1-Figure 3 The above-mentioned claw includes a first seat 1 and a second seat 2 combined with the first seat 1, wherein the first seat 1 has an opening in the central area, and the second seat 2 also has an opening in the central area.

[0035] The central area after the first seat 1 and the second seat 2 are combined is a through groove.

[0036] See also Figure 2 The claw also includes a toothed disc 11 arranged in the second seat 2 and coincident with the axis of the second seat 2, and a slide groove 5 arrayed around the axis of the second seat 2, and the slide groove 5 is a limiting groove of the movable part in the claw.

[0037] It should be noted that the surface where the second seat 2 is combined with the first seat 1 has a groove, which is the mounting groove of the toothed disc 11. In addition, the number of the slide grooves 5 corresponds to the number of the movable parts in the claw.

[0038] The back of the toothed disc 11 is a disc-shaped spiral groove 12. It should be noted that the teeth at the toothed disc 11 are Figure 2 The disc spiral groove 12 is facing downward from the perspective shown. Figure 2 Shown facing upward.

[0039] The movable part in the above-mentioned claw includes a first slider 3 that slidably cooperates with the slide groove 5, and a pad 4 that is combined with the first slider 3 and is used to slidably cooperate with the second slider 7, wherein the first slider 3 extends into the disc spiral groove 12 and drives the disc spiral groove 12.

[0040] It can be determined from the above that when the toothed disc 11 rotates axially, the first slider 3 and the cushion block 4 combination will slide along the range where the slide groove 5 is located. Figure 2 When rotating clockwise from the perspective shown, the first slider 3 and the cushion block 4 combination will approach the axis of the second seat 2 . Conversely, when rotating counterclockwise, the first slider 3 and the cushion block 4 combination will move away from the axis of the second seat 2 .

[0041] See also Figure 2 In this embodiment, a knob 6 is provided at the junction of the first seat 1 and the second seat 2 , and the knob 6 has helical teeth, wherein the helical teeth in the knob 6 extend to the toothed disc 11 and mesh with the toothed disc 11 .

[0042] Please continue reading Figure 2 As described above, the first slider 3 extends into the disc spiral groove 12. Specifically, a clamping block 13 is provided at the bottom of the first slider 3, and the clamping block 13 extends into the disc spiral groove 12. In this way, when the toothed disk 11 rotates axially, the disc spiral groove 12 uses the clamping block 13 to make the first slider 3 slide relative to the slide groove 5.

[0043] It is important to note in this embodiment that after the inner sleeve enters the surrounding space, it is supported by the extension portion in the movable part of the claw.

[0044] Further explanation, the extension part in the movable part of the claw is Figure 1-Figure 3 The pad extension part 9 shown is combined with the pad 4, and there is an insert block passing through the second slider 7 at the joint. This arrangement, on the one hand, can use the pad extension part 9 as an inner sleeve to enter the supporting part in the surrounding space, and on the other hand, after the pad extension part 9 is combined with the pad 4, it can limit the sliding of the second slider 7 in the height direction.

[0045] Further, the second slider 7 has a through slot 8, and the through slot 8 has an end (a closed section) that limits the second slider 7 from slipping off the pad 4. In this embodiment, in order to facilitate personnel to pull the second slider 7, Figure 3 A handle 10 is provided at the bottom of the second sliding block 7 as shown.

[0046] In this embodiment, the second slider 7 slides with resistance with the movable part in the claw. Specifically, there is a large friction coefficient between the contact surface of the second slider 7 and the cushion block 4. This setting can maintain the relative position of the second slider 7 and the cushion block 4 when no one is controlling the second slider 7.

[0047] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0048] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
