DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figure 1-Figure 4 As shown, a dump truck cylinder support in one embodiment of the utility model includes a support body 1, a stabilizing mechanism 2 and a buffer mechanism 3.

[0032] Among them, the support body 1 has a mounting rod 101 mounted on it, a pair of support arms are mounted on the mounting rod 101 , and a cylinder body 102 is mounted on the mounting rod 101 .

[0033] like Figure 1-Figure 4 As shown, a stabilizing mechanism 2 is installed on the support body 1, and the stabilizing mechanism 2 includes a bidirectional threaded rod 201. A handle is installed at one end of the bidirectional threaded rod 201, which has a rotating function. The rotation of the bidirectional threaded rod 201 can drive the movement of a pair of support arms.

[0034] In addition, a limit rod 202 is provided on the support body 1, which has the benefit of limitation, so that the support arm can be converted from rotation to linear sliding when moving on the bidirectional threaded rod 201.

[0035] In other words, the first support 203 is fixedly installed on the support body 1, the bidirectional threaded rod 201 is arranged to penetrate the first support 203, and the bidirectional threaded rod 201 is installed with bearings between the first support 203, which has the benefit of support. By installing the first support 203, the bidirectional threaded rod 201 and the limit rod 202 can be installed more stably.

[0036] Secondly, a plurality of slide grooves 204 are formed on the support body 1, and a pair of support arms match the slide grooves 204, which facilitates the sliding of the support arms, thereby making the sliding arms more stable.

[0037] like Figure 1-Figure 4 As shown, a pair of second supports 205 are fixedly mounted on the support body 1, and the limiting rod 202 is fixedly mounted between the pair of second supports 205 to provide support. The stability of the installation of the limiting rod 202 can be ensured by the support of the second supports 205.

[0038] like Figure 2-Figure 4As shown, a ratchet 206 is installed at the other end of the second support 205. The ratchet 206 passes through the second support 205 and is connected to the bidirectional threaded rod 201. It has the advantage of rotating according to the rotation of the bidirectional threaded rod 201, thereby facilitating the clamping of the clamping block 208 to the ratchet 206.

[0039] like Figure 3-Figure 4 As shown, a support rod 207 is fixedly mounted on the second support 205 at the other end, which has the benefit of support. The installation of the support rod 207 facilitates the arrangement of the block 208.

[0040] In addition, a clamping block 208 is provided on the support rod 207, which has the function of clamping the ratchet 206, thereby preventing the ratchet 206 from rotating in the reverse direction.

[0041] like Figure 3-Figure 4 As shown, the block 208 matches the ratchet 206 , and a torsion spring 209 is installed between the support rod 207 and the block 208 , which has a rebound effect, thereby controlling the block 208 so that the block 208 can be moved by the rotation of the ratchet 206 .

[0042] like Figure 2-Figure 4 As shown, a buffer mechanism 3 is installed on the support body 1, and the buffer mechanism 3 includes a pair of connecting chambers 301. The pair of connecting chambers 301 are respectively installed on the support arms and have the function of connecting to the support arms, so that the corresponding mechanism can be installed in the connecting chambers 301.

[0043] like Figure 2-Figure 4 As shown, the mounting rod 101 passes through the connecting chamber 301 , and the connecting chamber 301 matches the mounting rod 101 .

[0044] like Figure 1-Figure 4 As shown, a pair of limiting plates 302 are provided on one side of the mounting rod 101 , and the pair of limiting plates 302 are matched with the connecting compartments 301 respectively, and have the function of limiting the cylinder body 102 , thereby reducing the sliding range of the cylinder body 102 on the mounting rod 101 .

[0045] like Figure 1-Figure 4 As shown, a pair of limiting plates 302 match the cylinder body 102, and a plurality of telescopic rods 303 are installed between the connecting compartment 301 and the limiting plates 302, which have a telescopic function and are convenient for receiving the thrust brought by the cylinder body 102 pushing the limiting plates 302, thereby facilitating contraction.

[0046] like Figure 1-Figure 4 As shown, multiple telescopic rods 303 are provided with buffer springs 304 on their outer sleeves. Multiple buffer springs 304 are installed between the connecting compartment 301 and the limiting plate 302, which have the benefit of buffering. Through the buffering of the buffer springs 304, the cylinder body 102 can be slowed down when it has a slight sliding.

[0047] Specifically, in order to ensure that the smaller cylinder body 102 is in a stable state, the cylinder body 102 needs to be installed on the mounting rod 101 first, and then the handle can be manually shaken, which will drive the rotation of the bidirectional threaded rod 201, so that the rotation of the bidirectional threaded rod 201 will drive the ratchet 206, so that the ratchet 206 will fluctuate the block 208 through the control of the torsion spring 209 when rotating, so that the block 208 will engage the ratchet 206, so that the bidirectional threaded rod 201 can be controlled to rotate in only one direction, and the bidirectional threaded rod 201 can be rotated while the block 208 is turned, and the bidirectional threaded rod 201 can rotate in the opposite direction, because the rotation of the bidirectional threaded rod 201 will drive a pair of support arms to approach each other, and in order to make the support arms slide more The two-way threaded rod 201 will move in the slide groove 204 when it slides, and the limit rod 202 will limit the pair of support arms to slide in a straight line. Therefore, the pair of support arms will approach the cylinder body 102 at the same time, and the movement of the support arms will drive the buffer mechanism 3. Therefore, when the support arms are close, the pair of limiting plates 302 will contact the cylinder body 102. When the cylinder body 102 slides during the movement, the stabilizing mechanism 2 will be used to limit the sliding range. At the same time, the cylinder body 102 will squeeze the limiting plate 302, and the telescopic rod 303 will shrink, so that the buffer spring 304 can play a buffering role. Therefore, the sliding range of the cylinder body 102 can be reduced through the setting of the corresponding mechanism, which is relatively stable.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0049] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
