DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the present utility model.

[0020] Please refer to Figures 1-4 The present utility model provides a technical scheme: a movable automobile maintenance lying board, which comprises a first lying board 1 and a second lying board 3, and a connecting rod 2 is hingedly arranged on each side of the end of the first lying board 1, and the other end of the connecting rod 2 is hingedly arranged on the outer side of the second lying board 3 away from the first lying board 1, and the second lying board 3 can be folded upwards of the first lying board 1 through the connecting rod 2, so as to shorten the overall length and floor area of the lying board and improve the space utilization.

[0021] A pair of rollers 4 are arranged on the lower surfaces of the ends of the first lying board 1 and the second lying board 3 away from each other, the wheel body can be selected from polyurethane rubber coating, and the hub can be selected from nylon 66 reinforced composite material. The first lying board 1 and the second lying board 3 form an automobile maintenance lying board, which is moved through the rollers 4 on the lower sides of the first lying board 1 and the second lying board 3, so as to be convenient and labor-saving in the process of repairing the automobile.

[0022] A foot brake can be installed on the roller 4 to fix the maintenance lying board. The roller 4 can be a universal wheel.

[0023] Second lying board positioning holes 11 are formed in the side surfaces of the second lying board 3 and the connecting rod 2, and a fixing pin 8 is arranged in the second lying board positioning holes 11, so that the connecting rod 2 and the second lying board 3 can be fixed by inserting the fixing pin 8, and the first lying board 1 is combined to form a complete lying board.

[0024] A U-shaped support frame groove 6 is formed in the upper surface of the first lying board 1, a U-shaped support frame 5 is hingedly arranged in the support frame groove 6, and a support groove corresponding to the support frame 5 is formed in the lower surface of the second lying board 3. When the second lying board 3 is rotated to be directly above the first lying board 1, the second lying board 3 can be supported by the support frame 5 to form a ladder or a seat, which is convenient for the staff to repair the automobile at a high place or to repair automobile parts while sitting, and has multiple functions and flexible use.

[0025] Preferably, the two side surfaces of the second lying plate 3 away from the end of the roller 4 and the two side surfaces of the support frame 5 are provided with corresponding support positioning holes 7, and a fixed pin 8 is arranged in the support positioning hole 7. After the second lying plate 3 is supported and fixed by the support frame 5, a stable triangular structure is formed between the support frame 5, the second lying plate 3 and the connecting rod 2, and deformation is not easy. However, since the connecting rod 2 is hingedly connected with the second lying plate 3 and the first lying plate 1, if the force point is shifted to the position of the end of the second lying plate 3 away from the top end of the support frame 5 when the second lying plate 3 is supported as a ladder or a seat, the second lying plate 3 is easy to be opened by rotating. Therefore, the fixed pin 8 is arranged on the support frame 5 and the second lying plate 3 to be fixed, so that the structure is more stable and the use safety is improved.

[0026] Meanwhile, when the folding maintenance lying plate is folded, the fixed pin 8 originally inserted into the second lying plate positioning hole 11 needs to be taken out, and at this time, the fixed pin 8 can be inserted into the support positioning hole 7 to be fixed, so that the loss of the positioning pin 8 can be avoided.

[0027] Further preferably, the fixed pin is made of 40Cr alloy steel, a ball groove is formed in one end of the side surface of the fixed pin 8, a ball 9 is arranged in the ball groove, the ball 9 is made of GCr15 bearing steel, and a spring is arranged between the ball 9 and the bottom of the ball groove. The fixed pin 8 can be conveniently inserted, and the fixed pin 8 can be prevented from sliding out of the corresponding groove by the ball 9 and the spring, so that the use safety is further improved.

[0028] The fixed pin 8 is designed in a common self-locking type, the pre-tightening force of the ball is 15N, the insertion resistance is less than 5N, and the pulling-out resistance is greater than 50N, so as to prevent accidental falling out.

[0029] Further, a pull ring groove is formed in the other end of the side surface of the fixed pin 8, and a pull ring 10 is rotatably arranged in the pull ring groove. The pull ring 10 can be more conveniently pulled out of the fixed pin 8. When not in use, the pull ring 10 can be rotated by 90 degrees to reduce the overall occupied space.

[0030] Further, one end of the fixed pin 8 close to the ball 9 is provided with a rounded corner to improve the success rate of blind insertion alignment of the fixed pin 8.

[0031] Preferably, a headrest 12 is arranged on the upper surface of the second lying plate 3. The headrest 12 is preferably a sponge rubber pillow or a memory sponge core layer + antibacterial PU leather outer layer, so that the head of the staff is more comfortable when maintaining the bottom of the vehicle.

[0032] Optionally, the first lying plate 1 is provided with moving wheels 13 on both sides of the end close to the second lying plate 3, and the moving wheels 13 are arranged at the middle position of the lying plate, corresponding to the position where the hands of the staff naturally droop when lying on the lying plate. The outer surface of the moving wheels 13 is provided with hand wheels 14 coaxially arranged with the moving wheels 13. When the longer vehicle body is maintained, the staff is not easy to move the maintenance lying plate through the legs, at this time, the moving wheels 13 can be driven to move the maintenance lying plate by rotating the hand wheels 14, and the use is more convenient.

[0033] The hand wheels 14 can be provided with a brake assembly commonly used in the prior art, so that the staff can fix the lying plate by manually braking.

[0034] Optionally, the side surface of the second lying plate 3 is provided with a gooseneck pipe 15, and the end of the gooseneck pipe 15 is provided with a fixing cylinder 16. The fixing cylinder 16 can be used to place a flashlight, so as to facilitate the staff to observe the vehicle bottom and maintain. After the flashlight is placed in the fixing cylinder 16, the irradiation position and angle thereof can be adjusted through the gooseneck pipe 15, and the adjustment is convenient and the operation is simple.

[0035] Further, the inner side surface of the fixing cylinder 16 is uniformly provided with a plurality of clamping strips 17 made of elastic rubber, which can clamp and fix the flashlight, and improve the use stability.

[0036] The parts not disclosed in the utility model are all prior art, and the specific structure, material and working principle are not described in detail. Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
