Problems solved by technology
[0004] When the door is opened, it will be driven down quickly by the gravity of the spare tire. The connection between the doors is relatively fragile and easily broken by it. If there is an obstacle at the bottom of the car, when the spare tire quickly drives When the door falls down, the door is not damaged, but the spare tire is easy to hit the obstacle, which is more likely to cause its damage

Embodiment
[0030] as attached figure 1 to attach Figure 8 Shown:
[0031] The invention provides a flexible installation and fixing device for a spare tire on the rear box door of a dump truck.
[0032] The inverted spare tire device frame 5 runs through the interior of the rear box door 1, the guide rail 2 is located below the box body 3, the storage compartment 4 is embedded in the box body 3, and the rear box door 1 and the guide rail 2 vertical hinge connections.
[0033] The undercut spare tire device frame 5 includes a capsule collection guide rail 51, a twisted coil 52, a downwardly moving extruding body 53, a three-sided buffer body 54, an undercut hook 55, an auxiliary rotating shaft 56, an arc body barb 57, an installation The moving back 58 and the controllable tray 59, the capsule collection guide rail 51 is located below the twisted volume 52, the top of the downwardly moving extruding body 53 is connected with the bottom of the three-side buffering body 54, and the unde...

The invention discloses a flexibly movable mounting and fixing device for a spare tire of a rear compartment door of a dump truck. The flexibly movable mounting and fixing device structurally comprises the rear compartment door, a guide slide rail, a compartment body, an object storage grid and a backward buckled spare tire device frame, wherein the backward buckled spare tire device frame penetrates through the interior of the rear compartment door, the guide slide rail is positioned below the compartment body, the backward buckled spare tire device frame comprises a bag receiving guide rail,a twisted coil, a downward moving extrusion body, a three-sided buffer round body and a controllable tray, the bag receiving guide rail is positioned below the twisted coil, and the spare tire is buckled on a buckle mounting frame and is integrated with an extended stabilizing layer. When the rear compartment door needs to be opened, a backward buckle hook is broken up upward by external force soas to drive an arc body barb to extrude the three-side buffer round body and the downward moving extrusion body downwards, so that the external force of the controllable tray moves inwards, the resistance of the bottom of the extended stabilizing layer originally positioned above the controllable tray is released, so that the spare tire slowly slides into the bottom, that is, the rear compartmentdoor does not need to bear load and is not damaged due to impact with obstacles due to over-speed drop.
Description
technical field [0001] The invention belongs to the field of dump trucks, and more specifically relates to a flexibly changeable mounting and fixing device for a spare tire on a rear box door of a dump truck. Background technique [0002] Its current dump truck spare tire is installed on the rear car door of the compartment, and it is relatively fixed with the car door, and the car door is opened and moved as a whole, which may even increase the unbearable weight of the car door. [0003] Based on the inventor's discovery above, the existing spare tire fixing device for dump trucks mainly has the following deficiencies, such as: [0004] When the door is opened, it will be driven down quickly by the gravity of the spare tire. The connection between the doors is relatively fragile and easily broken by it. If there is an obstacle at the bottom of the car, when the spare tire quickly drives When the door falls down, the door is not damaged, but the spare tire is easy to hit th...
