[0020] The technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] As Figures 1-4 shown, a disassembly and assembly tool for a flat tire emergency safety device includes: a support disk 1, the support disk 1 is a disk-shaped structure, and a plurality of connecting rods 2 are fixedly connected to the circumference of the support disk 1. A sliding sleeve 12 is slidably arranged on the connecting rod 2, and a through docking hole is provided on the sliding sleeve 12.

[0022] The inside of the connecting rod 2 is hollowly arranged, and sliding rods 9 are symmetrically slidably arranged inside the connecting rod 2. The sliding rods 9 are strip-shaped structures. A plurality of positioning columns 91 are fixedly connected to the sides of the two sliding rods 9 away from each other. By arranging a plurality of positioning columns 91, tires of different sizes can be adapted. Fixing holes 22 adapted to the positioning columns 91 are provided on the side of the connecting rod 2, and the positioning columns 91 can pass through the corresponding fixing holes 22 and extend to the outside of the connecting rod 2.

[0023] At positions near both ends inside the connecting rod 2, double-headed screws 10 are symmetrically rotatably connected. Opposite helical threads are provided at both ends of the outer surface of the double-headed screw 10. Specifically, limiting rings (not shown in the figure) are symmetrically fixedly connected to the outside of the double-headed screw 10. Annular grooves adapted to the limiting rings are provided on the sliding rods 9, and the limiting rings are connected in the corresponding limiting grooves, so that the double-headed screw 10 can only rotate at a fixed position and the position of the double-headed screw 10 cannot change.

[0024] The double-headed screw 10 penetrates through the two sliding rods 9, and the two sliding rods 9 are respectively threadedly connected to both sides of the double-headed screw 10. The ends of the double-headed screw 10 extend to the outside of the connecting rod 2, which is convenient for the staff to rotate the double-headed screw 10 outside, so that the two sliding rods 9 approach or move away from each other.

[0025] Fixing grooves 21 are provided at the upper ends of the connecting rods 2. The positions of the fixing grooves 21 correspond to the positions of the fixing holes 22 one by one, that is, the fixing grooves 21 and the fixing holes 22 are on the same vertical plane. Colored stickers are pasted on the bottom of the fixing grooves 21, and different colors of the stickers correspond to tires of different sizes.

[0026] Guide rods 11 are symmetrically fixedly connected inside the connecting rod 2. Both ends of the guide rods 11 pass through the corresponding sliding rods 9, and the guide rods 11 are used to realize the guiding function of the sliding rods 9.

[0027] A support rod 3 is fixedly connected to the bottom end of the sliding sleeve 12, and a pressing rod 4 is fixedly connected to the bottom end of the support rod 3.

[0028] A threaded rod 6 is arranged in the middle of the support disk 1. The threaded rod 6 can pass through the support disk 1. Above the support disk 1, a threaded sleeve 13 is arranged. The threaded sleeve 13 is threadedly connected to the outside of the threaded rod 6. A handle 5 is fixedly connected to the outside of the threaded sleeve 13. By setting the handle 5, it is convenient to rotate the threaded sleeve 13. The bottom end of the threaded rod 6 is fixedly connected to a fixed sleeve 8, and a stop rod 7 is arranged inside the fixed sleeve 8.

[0029] Working principle:

[0030] Select a sticker of the corresponding color according to the size of the tire to be operated. Slide the sliding sleeve 12 to the position of the sticker of the corresponding color. At this time, the docking hole of the sliding sleeve 12 overlaps with the corresponding fixing hole 22. Rotate the double-headed screw rod 10 to make the two sliding rods 9 move away from each other until the positioning posts 91 on the sliding rods 9 pass through the fixing hole 22 and extend to the outside. Among them, two symmetrically arranged positioning posts 91 pass through the fixing hole 22 and the docking hole on the sliding sleeve 12 in sequence, so that the position of the sliding sleeve 12 is fixed.

[0031] Remove the tire, use a tire changer to open the tire, pass the stop rod 7 through the fixed sleeve 8, pass the threaded rod 6 through the center hole position of the wheel rim, place the support disk 1, connecting rod 2, support rod 3, and pressure rod 4 as a whole on the tire to be operated. Above the support disk 1, screw the threaded sleeve 13 onto the threaded rod 6. Keep rotating the handle 5 until the threaded sleeve 13 keeps descending. The threaded sleeve 13 transfers the pressure to the support disk 1. The support disk 1 drives the support rod 3 and the pressure rod 4 to move downward through the connecting rod 2, so that the tire is pressed down until the rim groove of the tire to be operated is completely exposed, and then the installation of the tire burst emergency safety device can be carried out.

[0032] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
