Problems solved by technology

[0004] The purpose of the present invention is to provide a mechanical support device for assisting the replacement of a spare tire, so as to solve the problem that the jack needs to be kept in a supporting state and cannot be evacuated during the use of the supporting vehicle, especially since most jacks adopt hydraulic support, if the jack is long If it is under high-load support working condition for a long time, there is a risk of failure if it is heavy; if some small jacks are used, it may cause problems such as structural deformation caused by long-term (or overload) use of the jack. At the same time, more attention is paid to practicality. The anti-slip measures used according to the road conditions have strong tolerance, simple structure, easy disassembly and carrying, and strong practicability

Embodiment 1

[0037] This device is a mechanical support device for assisting the replacement of spare tires. It is mainly used to replace hydraulic jacks or simple mechanical jacks for long-term support. After supporting the device at a high height, the jack can be stowed and replaced by the device, specifically:

[0038] refer to Figure 6 , take this device on the soft slope road surface as an example, when in use, twist and lift and withdraw the reinforcement screw 105, rotate the base screw disk 102, so that the base screw disk 102 overlaps with the step installation disk 101, at this time, the ground rivet 103 stretches out the bottom of the base screw sleeve plate 102 from the rivet relief opening 104, and the vehicle is jacked up by the jack, and after the device is placed under the vehicle chassis, the support top blocks 14 at the two ends of the support cross bar 11 are positioned at the vehicle chassis and can be supported. Below the force position, then pull the limit pull ring...

Embodiment 2

[0041] refer to Figure 7 , is the use situation in the hard slope road surface, and other operation processes are similar to embodiment one.

Embodiment 3

[0043] refer to Figure 8 , it adopts the support structure of ball head rod 501. In use, the ball head rod 501 is directly screwed into the screw hole at the lower end of the tilt support column 5, and then the ball head at the lower end of the ball head rod 501 is pushed against the step mounting plate 101 The semi-spherical sunken groove provided at the upper central part is sufficient, and the other operating procedures are similar to those in Embodiment 1.

[0044] The auxiliary support device of the present invention is used to replace the jack for long-term support. When in use, the vehicle is first lifted up by the jack, and then the jack can be put away after the device is placed under the vehicle chassis, and the device is used for replacement support. Since the device is high The strength of the purely mechanical support structure can avoid the risk of failure and failure of the jack for long-term support, and at the same time avoid the structural deformation caused...

Abstract

The invention discloses a mechanical support device for assisting in replacing a spare tire, to solve that problem that a jack needs to be kept in a support state all the time and cannot be evacuatedduring use of the support vehicle. The mechanical support device includes a chassis assembly, a step mounting plate and a U-shaped mounting frame are arranged on the chassis assembly, the internal cavity of the U-shaped mounting frame is provided with a U-shaped crankshaft, the U-shaped crankshaft and the U-shaped mounting frame are rotationally connected through a bearing, a connecting shaft is arranged in the middle of the U-shaped crankshaft, the outer wall of the connecting shaft is rotatably sleeved with a tilting sleeve, the upper part of the tilting sleeve is sequentially provided witha tilting support column, a lifting adjusting cylinder, a lifting slide block, a lifting support rod, a spring limit plate, an extension spring and a support cross rod, the bottom of the support crossrod is hinged to the top of the lifting support rod, a distance adjusting slide block and a support top block are arranged on the support cross rod, and a limiting mechanism is arranged in the lifting adjusting cylinder. The device has the advantages of simple structure, convenient disassembly, assembly and carrying and strong practicability, can be used on different roads, especially on slopingroads, and has anti-skid measures.

Description

technical field [0001] The invention relates to a mechanical support device for assisting the replacement of a spare tire, and belongs to the technical field of mechanical support devices. Background technique [0002] With the improvement of the economic level, cars have gradually entered thousands of households and become a means of transportation for people to travel. But when the car is driving on the road and suddenly blows out, changing the tire becomes a great trouble; the most common way is to use a jack to change the tire, but there is a problem that the jack cannot be placed stably on the outdoor slope terrain. Based on this, the application number CN201720578400.X discloses "a new type of auxiliary jack support device for automobiles", which includes a storage tank, a bottom pad, a support body and a threaded rod. There is a knob at one end of the threaded rod and a movable plate at the other end. , the fixing bar is installed on the fixed plate body; the interna...
