When the long groove 40 on the pressure rod 4 presses the pressure rod 4, the angle is changed, so that the adjusting sleeve is not limited.
An adjusting sleeve 5 is fixed in the middle of a second connecting rod 13 of the connected double-tripod 1, and the trip rod 7 is arranged in the adjusting sleeve 5. In order to facilitate the telescopic action of the hook rod 7, the adjusting sleeve 5 is a hollow sleeve, a plurality of adjusting holes 51 are drilled in the side wall of the sleeve, the hook 8 is connected with the hook rod 7, the hook rod 7 penetrates through the adjusting sleeve 5, the length of the hook rod 7 can be extended and contracted by fixing the different adjusting holes 51 in the adjusting sleeve 5 and the hook rod 7, and the distance between the adjusting hole 51 at the highest position and the adjusting hole 51 at the lowest position on the adjusting rod 5 is the distance between an automobile tire and a steel ring.
In addition, in order to firmly and temporarily connect the hook 8 with the automobile steel ring, an end hook 81 is designed at the end part, the end hook 81 is vertically bent towards one side, and a supporting plate 82 is designed at the upper part of the end hook 81. When the adjusting device is used, the end hook 81 extends into the screw hole in the automobile steel ring and hooks the side wall to enable the adjusting sleeve 5 to generate pulling resistance when the adjusting sleeve is stretched upwards, and the abutting plate 82 abuts against the upper part of the screw hole in the automobile steel ring to prevent the whole clamping hook 8 from sinking into the screw hole.
The upper end of the adjusting tube 2 is fixed on the pressure rod 4, one end of the push rod 61 is arranged in the adjusting tube 2, the other end of the push rod 61 is provided with a pressure plate 6, and the pressure plate 6 is arranged on an automobile tire. In fact, the pressure plate is crescent-shaped and can be attached to the automobile tire, and the inner arc radius of the pressure plate is between the inner diameter of the automobile tire and the outer diameter of the steel ring. Of course, the shape of the fan can be made into a crescent-like arc shape or a fan shape, a fan ring shape and the like.
The right-angle positions of the right-angled triangle 11 on the connected double-tripod 1 are respectively provided with a second connector 15, the upper end of the rear fork support 3 is connected to the second connectors 15 on the connected double-tripod 1, and the lower end of the rear fork support 3 is connected to a small fork 31 clamped on a steel ring screw hole. During use, the small fork 31 at the bottom of the rear fork bracket 3 is used for abutting against a steel ring screw hole on an automobile tire and cannot be sunk into the screw hole. Thus, the rear fork support 3 can be used to support the conjoined double-tripod 1, and when the pressure rod 4 applies downward pressure, it is supported on the edge of the screw hole by the small fork 31, providing a supporting force, and not so much as the sliding causes the unbalance of the whole support.
In order to facilitate the disassembly of the large-diameter automobile tire during use, one side of the pressure rod is also provided with an extension rod.
In order to make the whole conjoined double-tripod 1 lighter and more convenient, a lightening hole is arranged in the right-angled triangle.
The utility model discloses an automobile tire extracting tool is shown in figure 2 in the use, and figure 2 is the utility model discloses automobile tire extracting tool's user state schematic diagram. In the using process, the automobile tire 9 lies on the ground or on a platform, the inner side of the automobile tire 9 is provided with a steel ring 91, and the steel ring 91 is provided with a plurality of screw holes which are used for fixing the automobile steel ring 91 on a frame, dismounting the automobile tire when dismounting is needed and placing the automobile tire 9 on the ground or on the platform in a lying manner.
Will the utility model discloses an automobile tire extracting tool makes up for pressure plate 6 of push rod 61 tip is pressed on tire 92, and the little fork 31 of 3 tip of back fork support supports in screw edge on steel ring 91, and simultaneously, adjusting sleeve 5 and trip rod 7 are adjusted to appropriate length, make the end on the trip 8 collude 81 and stretch into on the steel ring relative position in the screw and collude in the inside wall, and support that board 82 then is located the screw outside.
When the connecting double-tripod 1 is used, the pressure rod 4 or the extension rod 41 is held and pressed downwards, an upward pulling force is generated on the adjusting sleeve 5, the clamping hook rod 7 and the clamping hook 8, and meanwhile, a downward pushing force is generated on the rear fork bracket 3 and the small fork 31, and the two components support the connecting double-tripod 1 to be balanced. At this time, the pressure rod 4 presses the hook rod 7 to generate a downward pressure, and the pressure is transmitted to the tire through the crescent-shaped pressure plate 6. When the pressure is sufficiently high, the tire 9 at the connecting position can be partially separated from the steel rim 91, and then the small fork 31 and the clamping hook 8 are switched to be in different screw holes, so that the contact position between the pressure plate 6 and the tire is switched, and the pressure is applied to partially separate the tire 9 from the steel rim 91. The tire and the steel ring are partially separated, and after the tire and the steel ring are completely separated, the opening-to-opening clamping ring on the steel ring is pried down by a prying bar, and the tire is turned over into a whole, so that the tire can be disassembled by operating according to the method. By the operation, the separation of the automobile steel rim 91 and the steel rim 91 on the tire 9 can be completed, and the disassembly work of the automobile tire is further completed. If the tire is a vacuum tire, the tire can be directly disassembled from the steel ring by a pry bar.
Although the present invention has been described above with reference to the embodiments of the present invention, it is not intended that the scope of the present invention be limited to the above-described structures, as long as the structures covered by the claims of the present invention are within the scope of protection. Equivalent alternative structures that would be obvious to those skilled in the art upon reading the foregoing description are intended to be within the scope of the present disclosure.
