Abstract
The utility model relates to a portable tire changer which comprises a bottom plate (1). The bottom plate (1) is provided with a long screw hole (1-1). The upper end of the bottom plate (1) is fixedly provided with a vertical shaft sleeve (2). A vertical shaft (8) capable of rotating in the vertical shaft sleeve (2) is sleeved in the vertical shaft sleeve (2). The upper end of the vertical shaft (8) extends out of the vertical shaft sleeve (2) and is connected with a supporting rod (7) through a pin shaft (6). One end of the supporting rod (7) is connected with a shovel arm (5) through the pin shaft (6). The lower end of the shovel arm (5) is connected with a first shovel board bracket (4) through the pin shaft (6). The first shovel board bracket (4) is provided with a first shovel board (3). The other end of the supporting rod (7) is connected with an air cylinder (9) through the pin shaft. A piston rod (10) of the air cylinder (9) is connected with a second shovel board bracket (11) through the pin shaft. The second shovel board bracket (11) is provided with a second shovel board. The shovel board at one side of the supporting rod is pressed down under the action of the air cylinder and the shovel board at the other side of the supporting rod is lifted up according to a lever principle, so that a tire is separated from a hub. The whole device is small and light, has low cost, is convenient to carry and is convenient to use.
Description
Technical field
The utility model relates to a kind of vehicle maintenance and repair machinery, particularly a kind of tyre removing and replacing machine.
Background technology
At present, the handling mode of motor tire mainly is that people's hammer is pounded and the thick stick sled, and labour intensity is big, and efficient is low, poor safety performance.Existing tyre removing and replacing machine is huge, heavy, complex structure, and the manufacturing cost height, one just has several tons of weights, carries very inconvenient.
The utility model content
Technical problem to be solved in the utility model is, a kind of portable tyre removing and replacing machine is provided, and has smaller volume and weight, and is easy to use, to overcome the defective of existing tyre removing and replacing machine.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme that is adopted:
Portable tyre removing and replacing machine, comprise base plate, offer long screw on the described base plate, it is characterized in that: described base plate upper end is installed with vertical shaft sleeve, be socketed with the vertical shaft that can rotate in vertical shaft sleeve in the described vertical shaft sleeve, described vertical shaft upper end is stretched out vertical shaft sleeve and is connected with strut bar by bearing pin; One end of described strut bar is connected with the shovel arm by bearing pin, and the lower end of shovel arm is connected with the first shovel board support by bearing pin, on the first shovel board support first shovel board is installed; The other end of strut bar is connected with cylinder by bearing pin, and the piston rod of described cylinder is connected with the second shovel board support by bearing pin, and the second shovel board support has second shovel board.
Good effect of the present utility model is:
The shovel board of strut bar one side presses down under the effect of cylinder, according to carrying on the lever principle strut bar opposite side shovel board, thereby tire is separated with wheel hub.Whole device small volume and less weight, with low cost, and be easy to carry, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Further specify the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, present embodiment comprises criss cross base plate 1, offers long screw 1-1 on the described base plate 1, and during use, bolt passes this long screw 1-1 base plate 1 and tire wheel hub are fixed, thereby this removing machine is fixed on the wheel hub.Described base plate 1 upper end is installed with vertical shaft sleeve 2, be socketed with the vertical shaft 8 that can in vertical shaft sleeve 2, rotate in the described vertical shaft sleeve 2, described vertical shaft 8 upper ends are stretched out vertical shaft sleeve 2 and are connected with strut bar 7 by bearing pin 6, one end of described strut bar 7 is connected with shovel arm 5 by bearing pin 6, the lower end of shovel arm 5 is connected with on the first shovel board support, 4, the first shovel board supports 4 by bearing pin first shovel board 3 that is used for the perk wheel hub is installed.The other end of strut bar 7 is connected with cylinder 9 by bearing pin 6, and the piston rod 10 of described cylinder 9 is connected with the second shovel board support, 11, the second shovel board supports 11 by bearing pin 6 and has second shovel board 12.
During use, tire keeps flat, and the long screw 1-1 on the base plate is alignd with screw on the wheel hub, by bolt, the shovel board of strut bar 7 both sides is inserted in the slit of wheel hub and tire respectively.Start cylinder 9, second shovel board 12 is pressed down, carry on first shovel board 3 of opposite side is corresponding, make tire loosening.Repeat aforesaid operations after making strut bar 7 rotating certain angle then, get loose fully until tire.
