[0029] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," etc., used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one; the terms "first," "second," and "third," as used herein, should not be considered as a limitation on the order of components, but are merely for distinguishing different components; the terms "comprising" or "including," etc., indicate that the elements or objects preceding "comprising" or "including" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0031] To more clearly describe the specific structural components of this adjustable wedge-shaped slider structure for a compressed garbage truck, in conjunction with the attached... Figures 1-3 This embodiment is described as follows:

[0032] like Figures 1-3 As shown, an adjustable wedge-shaped slider structure for a compression garbage truck includes a sliding plate 1 and a matching slide rail 7. The inner side wall of the slide rail 7 is provided with at least one vertical guide rail surface 701, and the upper and lower side walls of the slide rail 7 are respectively provided with horizontal guide rail surfaces 702. The sliding plate 1 is fixedly connected to the slider body 6 through a slider horizontal adjustment mechanism. The slider horizontal adjustment mechanism can adjust the fit between the slider body 6 and the vertical guide rail surface 701 along the width direction of the slide rail 7.

[0033] The upper and lower ends of the slider body 6 are respectively provided with slots 601. Each slot 601 is provided with a wedge slider group. Each wedge slider group includes: a wedge active slider 9 that can slide horizontally along the length direction of the slide 7 and has a first inclined working surface; and a wedge driven slider 8 that can slide along the height direction of the slide 7 and has a second inclined working surface that slides and fits against the first inclined working surface.

[0034] The outer wall of the wedge-shaped driven slider 8 is provided with a horizontal abutment surface 801 that slides and fits against the horizontal guide rail surface 702, and its end is provided with a vertical abutment surface 802 that slides and fits against the vertical guide rail surface 701. The horizontal abutment surface 801 is parallel to the horizontal guide rail surface 702, and the vertical guide rail surface 701 is parallel to the vertical abutment surface 802. The slider body 6 is provided with a slider vertical adjustment mechanism that is connected to the wedge-shaped active slider 9. The horizontal displacement of the driven wedge-shaped active slider 9 is used to control the position of the wedge-shaped driven slider 8 in height, so as to adjust the fit between the horizontal abutment surface 801 and the horizontal guide rail surface 702.

[0035] The adjustment of this wedge slider structure includes two directions: first, adjusting the distance and fit between the wedge slider assembly and the vertical guide rail surface 701 in the horizontal direction; and second, adjusting the distance and fit between the wedge slider assembly and the two horizontal guide rail surfaces 702 in the height direction. Through the adjustment in these two directions, the slider body 6 and the wedge slider assembly can run smoothly in the slide rail 7.

[0036] Horizontal adjustment is achieved by a slider horizontal adjustment mechanism:

[0037] For example, the slider horizontal adjustment mechanism includes a slider fixing shaft 2, a first locking bolt 3, a fixing shaft locking plate 4, and a first locking nut 5. One end of the slider fixing shaft 2 passes through a pin hole on the slide plate 1, and the other end is connected to the slider body 6. The fixing shaft locking plate 4 is fixed on the slide plate 1, and the first locking nut 5 is fixedly connected to the fixing shaft locking plate 4. The first locking nut 5 is threadedly engaged with the first locking bolt 3, and the first locking bolt 3 applies a preload force to the slider fixing shaft 2 toward the vertical guide rail surface 701. During adjustment, the first locking bolt 3 is rotated to screw in relative to the first locking nut 5. The end of the first locking bolt 3 presses against the slider fixing shaft 2, and the slider body 6 moves toward the vertical guide rail surface 701 along with the slider fixing shaft 2, ensuring the fit between the vertical contact surface 802 and the vertical guide rail surface 701.

[0038] Specifically, the slider fixing shaft 2 is inserted into the slider body 6 to facilitate the installation and disassembly of the slider body 6.

[0039] The height is adjusted by a vertical adjustment mechanism for the slider:

[0040] First, the wedge-shaped driven slider 8 and the wedge-shaped active slider 9 are each triangular or trapezoidal. The first inclined working surface of the wedge-shaped active slider 9 is in contact with the second inclined working surface of the wedge-shaped driven slider 8. When the wedge-shaped active slider 9 is pushed, due to the squeezing and guiding of the inclined working surfaces, the horizontal movement of the wedge-shaped active slider 9 is converted into the vertical movement of the wedge-shaped driven slider 8, thereby causing the horizontal contact surface 801 of the wedge-shaped driven slider 8 to change in height.

[0041] For example, the vertical adjustment mechanism of the slider includes a second locking nut 10, a slider locking plate 11, and a second locking bolt 12. The slider locking plate 11 is fixed to the slider body 6 and limits the wedge-shaped slider group in the length direction of the slide rail 7. The second locking nut 10 is fixedly connected to the slider locking plate 11. The second locking bolt 12 is threadedly engaged with the second locking nut 10 and applies a horizontal preload to the wedge-shaped active slider 9. During adjustment, the second locking bolt 12 is rotated to screw in relative to the second locking nut 10. The end of the second locking bolt 12 presses against the wedge-shaped active slider 9, thereby causing the horizontal contact surface 801 of the wedge-shaped driven slider 8 to produce a vertical displacement. At the same time, the vertical adjustment mechanisms of the two sliders on the same slider body 6 are adjusted so that the horizontal contact surfaces 801 of the two wedge-shaped slider groups move closer or further apart in the height direction of the slide rail 7, so as to synchronously adjust the gap and fit with the two horizontal guide rail surfaces 702.

[0042] See Figure 2In the above embodiment, the slot 601 is open on one side facing the vertical guide rail surface 701 and the horizontal guide rail surface 702. The horizontal abutment surface 801 and the vertical abutment surface 802 extend from the corresponding open area to the outside of the slot 601. The wedge-shaped driven slider 8 is used as the direct contact part with the slide rail 7. Only the wedge-shaped driven slider 8 needs to be replaced later.

[0043] See Figure 3 In the above embodiment, the wedge-shaped active slider 9 has an auxiliary abutment surface 901 that is flush with the vertical abutment surface 802, which increases the contact area with the vertical guide rail surface 701 and improves the stability of operation.

[0044] The parts not described in detail in the above embodiments are existing technologies.

[0045] It should be noted that although the present invention has been described through the above embodiments, there may be other various embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but all such changes and modifications should fall within the scope of protection of the appended claims and their equivalents.
