Detailed Description

Fig. 1 is a schematic structural view of the present invention; fig. 2 is an exploded schematic view of the present invention, and fig. 3 is a schematic structural view of the positioning rod. Referring to fig. 1 to 3, a tire pressing device comprises a positioning rod 1, a screw rod 2, a support 3, a bent rod 4 and a pressing block 5, wherein one end of the bent rod 4 is connected with the support 3, the other end of the bent rod 4 is connected with the pressing block 5, the screw rod 2 is arranged in the middle of the support 3, the screw rod 2 is connected with the positioning rod 1, the positioning rod 1 comprises a movable part 1.1 and a fixed part 1.2, the length L1 of the positioning rod 1 is smaller than the diameter D of a central hole of a wheel hub when the movable part 1.1 is folded, and the length L2 of the positioning rod 1 is larger than the diameter D of the central hole of the wheel hub when the movable part 1.1 is unfolded; the utility model discloses a structure that the locating lever was folded up for locating lever 1 can easily pass wheel hub centre bore, and needn't move heavy tire, passes wheel hub centre bore back, and the movable part 1.1 of locating lever 1 is expanded and is just played the effect of location, makes the use of this device very convenient.

Referring to fig. 2, the movable portion 1.1 and the fixed portion 1.2 of the positioning rod 1 are movably coupled by a pin 1.3, in this embodiment, a first through hole 1.4 is disposed on the movable portion 1.1, a second through hole 1.5 is disposed on the fixed portion 1.2, the pin 1.3 passes through the first through hole 1.4 and the second through hole 1.5 respectively, and a positioning block 1.6 is disposed on the fixed portion 1.2, referring to fig. 3, when the movable portion 1.1 is folded, the movable portion 1.1 is perpendicular to the fixed portion 1.2, and when the movable portion 1.1 is unfolded, the movable portion 1.1 and the fixed portion 1.2 are on the same straight line under the action of the positioning block 1.6; the screw 2 is arranged perpendicular to the middle of the bracket 3, the upper end of the screw 2 is provided with an inner hexagonal cylinder head 2.1, the lower end of the screw 2 is connected with the positioning rod 1, and a fixing part 1.2 of the positioning rod 1 is provided with a screw hole 1.7 matched with the screw 2; the number of the bent rods 4 is five, the lower end face of the support 3 is provided with five slots 3.1 matched with the bent rods 4, the number of the slots 3.1 is five, the middle of the support 3 is provided with a bearing seat 3.2 and a bearing 3.3, and the screw rod 2 penetrates through the bearing 3.3 to be movably connected with the support 3.

FIG. 4 is a schematic structural diagram of a pressing block, as shown in FIG. 4, an included angle C between the pressing block 5 and the bent rod 4 is smaller than 90 degrees, and is determined according to the specification and performance of the tire, so that the pressing block 5 is more attached to the tire tread when pressing down the tire, the tire is not easily damaged, and the inclined plane can better tighten the tire tread when pressing down, a bulge is not formed, and the automobile tire burst safety device is more conveniently installed; the bottom surface and the edge of the pressing block 5 are cambered surfaces.

Fig. 5 is the utility model discloses a user state picture, as shown in fig. 5, the utility model discloses during the use, need not to be equipped with dedicated handle that shakes, only need use usual hexagonal spoon alright with stirring screw rod 2 for upward movement is done to 1 relative screw rod 2 of locating lever, because the length that 1 expandes of locating lever is greater than wheel hub's centre bore diameter D, so locating lever 1 can be blocked in the bottom of wheel hub centre bore, thereby make briquetting 5 will overlap the tire outside wheel hub and push down, make the child lip of tire break away from and move down the certain distance with wheel hub, finally vacate the operating space of dismouting.

In a word, the utility model discloses need not to lift up the tire during use, alleviate intensity of labour, the operation is very convenient, and the briquetting is less than 90 with the contained angle of knee, better protects the tire to need not to be equipped with the dedicated handle that waves, more save the cost, be adapted to operation under open-air adverse circumstances or the emergency environment.
