Abstract

The utility model relates to a folding cushion for automobile repairing, which is convenient to carry and can slide in any orientations. The utility model is composed of a bottom board, a folding board, a castor set, a pillow, a ratchet mechanism, etc., wherein, one end of the bottom board is connected with the ratchet mechanism provided with the pillow; both sides of the bottom board are connected with the folding board by hinges, forming a main body of the repairing cushion; the foldable castor set is arranged under the bottom board. The utility model has novel conception and comfortable and convenient use, and can be used as an auxiliary tool for a maintainer to enter under the automobile when the driving fault happens. The utility model can reduce the labor intensity and increase the work efficiency, and can be used as a simple rest and cooling bed for the driver and the passenger in normal times.

Description

Folding cushion for automobile repairing

The utility model relates to a kind of collapsible Mechanical Help pad of lying.

Vehicle in the process of moving, unavoidable et out of order, service personnel often need pierce the car tripe, lies in ground, and position, car bottom is overhauled.For the clothing of not making dirty, cloth sheet commonly used, straw mat so that on the car seat cushion etc. be laid on the ground, do not only time-consuming, effort like this, and transposition is difficult for.

The utility model is at above-mentioned existing problems, and it is folding to propose a kind of energy, be convenient to carry with car, during use as required fast and reliable ground regulate the pillow height, the Mechanical Help that can slide flexibly on the ground again simultaneously pad of lying.

The utility model is made up of base plate, folded sheet, castor group, pillow and ratchet device etc.One end of base plate links to each other with the ratchet device that has pillow, and its both sides then link to each other with folded sheet by hinge, forms the main body of repairing pad, folding castor group also is housed below the base plate.Ratchet device is freed button, pawl base, connecting panel, torsion spring, ratchet shaft etc. by pillow support, ratchet, ratchet, ratchet torsion spring, ratchet and is formed.

Advantage of the present utility model is: can fold, portable band, the operator only need open the pad of lying during use, lies in and pedals bipod on the pad, just can easily slip into any orientation of car tripe and carry out the car inspection and maintenance operation, the clothing of can not making dirty can improve work efficiency, and bigger value of service is arranged.Use when in addition, it also can be used as simple and easy bed for rest.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a birds-eye view of the present utility model;

Fig. 3 is the A-A cutaway view of Fig. 1 of the present utility model;

Fig. 4 is a ratchet device front view of the present utility model;

Fig. 5 is the birds-eye view of ratchet device of the present utility model.

With reference to each accompanying drawing, 1 among the figure is pillow, and 2 is ratchet device, and 3 is hinge, and 4 is folded sheet, and 5 is base plate, 6 is the castor group, and 7 is the pillow support, and 8 is ratchet, and 9 is ratchet, and 10 is the ratchet torsion spring, 11 free button for ratchet, and 12 is pawl base, and 13 is connecting panel, and 14 is torsion spring, and 15 is ratchet shaft.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

It is that clockwise direction is rotatable that one end of base plate 5 is being fixed a cover function, the ratchet device 2 that the one end that anticlockwise direction is blocked by ratchet 9 and pillow 1 are fastening, and ratchet 8 is riveted into one when assembling with pillow support 7.When clockwise direction is pulled pillow support 7, ratchet 8 serves as that axle rotates with ratchet shaft 15 thereupon, the height of pillow 1 also just increases gradually, when the user stops to pull pillow support 7, ratchet 8 is blocked by ratchet 9, pillow 1 just can rest on the ideal position after pulling, and ratchet 8 can guarantee that pillow 1 does not rotate because of bearing anti-clockwise power when operation.Ratchet 9, ratchet torsion spring 10, ratchet are freed button 11 with being contained on the pawl base 12, when pressing down ratchet and free button 11, ratchet 9 is freed under the effect of button 11 at ratchet, the tooth portion of throwing off ratchet 8, the unidirectional rotation effect of ratchet 8 disappears thereupon like this, fastening all-in-one-piece pillow 1, pillow support 7 and ratchet 8 just can be got to the leftmost side (as shown in Figure 4) under the effect of torsion spring 14, make pillow be in nadir, so that again pillow 1 is regulated from low to high.And free button 11 when unclamping ratchet, under the effect of ratchet torsion spring 10, ratchet 9 just automatically resets, again block ratchet 8, there is a positive stop lug boss bottom of pillow support 7, it can guarantee to get to the left side during nadir when pillow 1, and is spacing because of contacting with connecting panel 13, is rotated further by anticlockwise direction to avoid pillow 1, pillow support 7 and ratchet 8 continuation.

5 times caster wheel groups 6 of base plate are made up of four castors, and every castor all can be done rotary folding to the inside.

It is of the present utility model that to sprawl step as follows:

Earlier with castor group 6 plates to the solid line position shown in Fig. 3 institute, free button 11 among pressing Fig. 4, make on the left of pillow 1 gets to, relieving folded sheet 4 is to position shown in Figure 2, at this moment, the utility model enters running condition.

The folding step of the present utility model is poly-as follows:

Earlier folded sheet 4 is folded into dotted line position as shown in Figure 3, (this moment, pillow 1 was under the effect of ratchet device 2 pillow 1 clockwise direction to be turned to as shown in Figure 1 dotted line position again, folded sheet 4 is compressed), at last castor group 6 is folded into dotted line position as shown in Figure 3, at this moment, oad minimum of the present utility model is easy to carry.

For making the utility model lighter, firm, shape meets simulation of human body simultaneously, when implementing, and base plate 5, folded sheet 4 can adopt the engineering plastics plate.
