Description

Technical Field

[0001] The utility model relates to the technical field of spare tire supports, in particular to a spare tire support. Background Art

[0002] The spare tire support is generally a special accessory on the vehicle, especially the spare tire of an off-road vehicle will be placed at the rear of the vehicle. When the off-road vehicle is moving, the body of the vehicle will rise and fall due to the shaking, which will drive the spare tire up and down as well. Therefore, it is necessary to increase the stability of the spare tire. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a spare tire support, which has the advantage of supporting the spare tire.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spare tire support, comprising a base, a rotating shaft is arranged in the base, a driving block which can rotate around the axis of the rotating shaft is sleeved on the rotating shaft, the base is provided with a chassis located above the driving block, a support plate is connected to the top of the chassis, and a rubber pier is fixedly connected to the bottom of the base.

[0005] By adopting the above technical solution, the rubber pier itself has a spring. After the spare tire support is located below the spare tire to support the spare tire, when the off-road vehicle body shakes, the rubber pier itself will undergo corresponding deformation, thereby better supporting the spare tire. When the spare tire needs to be supported, the support plate needs to be lifted. At this time, the rotating shaft drives the driving block to rotate. The rotation of the driving block will drive the chassis to move upward, thereby driving the support plate to move, thereby supporting the spare tire. When the spare tire does not need to be supported, the support plate needs to be moved downward. At this time, the rotating shaft drives the driving block to rotate. The rotation of the driving block will drive the chassis to move downward, thereby driving the support plate to move. The support plate and the spare tire will be separated, thereby no longer supporting the spare tire.

[0006] The utility model is further configured as follows: the driving block includes a convex block in the circumferential direction.

[0007] By adopting the above technical solution, after the driving block rotates around the axis of the rotating shaft, the driving block will drive the convex block to rotate, and the convex block can be lifted or the chassis can be lowered as the convex block rotates.

[0008] The utility model is further configured as follows: a threaded column is integrally connected to the middle of the chassis, and the support plate is sleeved on the outer side of the threaded column and is threadedly connected to the threaded column.

[0009] By adopting the above technical solution, the supporting plate is rotated to allow the supporting plate to rotate and move along the axis of the threaded column, so as to adjust the relative distance between the supporting plate and the chassis.

[0010] The utility model is further configured as follows: a reinforcing rod is arranged inside the threaded column.

[0011] By adopting the above technical solution, the provision of the reinforcing rod increases the internal structural strength of the threaded column.

[0012] The utility model is further configured as follows: the base is provided with a clamping ring located on the outside of the supporting plate, the clamping ring is integrally connected with a limiting block located in the base, a spring is provided above the chassis, and the other end of the spring is connected to the limiting block.

[0013] By adopting the above technical solution, the setting of the spring increases the stability of the threaded connection between the threaded column and the support plate. Since the limit block is located in the base, a part of the clamping ring integrally connected to the limit block will also be located in the base to prevent the support plate from separating from the base.

[0014] The utility model is further configured as follows: one end of the rotating shaft is connected with a handle.

[0015] By adopting the above technical solution, the rotating handle drives the rotating shaft to rotate.

[0016] In summary, the utility model has the following beneficial effects:

[0017] The rubber pier itself has a spring. After the spare tire support is located under the spare tire and supports the spare tire, when the off-road vehicle body shakes, the rubber pier itself will deform accordingly, thereby better supporting the spare tire. When the spare tire needs to be supported, the support plate needs to be lifted. At this time, the rotating shaft drives the driving block to rotate. The rotation of the driving block will drive the chassis to move upward, thereby driving the support plate to move, and the support plate and the spare tire will be separated, thereby no longer supporting the spare tire. It is worth noting that the spring will not shake repeatedly when it is in a compressed state, and the two states of the driving block correspond to the two states of raising and retracting the support plate. When only the spare tire needs to be supported, the support plate can be lifted. Figure 3 When support is not needed, return the drive block to the position shown in Figure 2 so that the support plate no longer contacts the spare tire, and then remove the entire support.

[0022] The utility model is further described with reference to the accompanying drawings.

[0029] Working principle:

[0030] The rubber pier itself has a spring. After the spare tire support is located under the spare tire and supports the spare tire, when the off-road vehicle body shakes, the rubber pier itself will deform accordingly, thereby better supporting the spare tire. When the spare tire needs to be supported, the support plate needs to be lifted. At this time, the rotating shaft drives the driving block to rotate. The rotation of the driving block will drive the chassis to move upward, thereby driving the support plate to move, and the support plate and the spare tire will be separated, thereby no longer supporting the spare tire. It is worth noting that the spring will not shake repeatedly when it is in a compressed state, and the two states of the driving block correspond to the two states of raising and retracting the support plate. When only the spare tire needs to be supported, the support plate can be lifted. Figure 3 When support is not needed, return the drive block to the position shown in Figure 2 so that the support plate no longer contacts the spare tire, and then remove the entire support.
