rainwater, and then obtains the service life of turntable 1 Extend, makes the more convenient to use of this device, the positive two sides of turntable 1 are welded with bearing 2, and the inner ring of bearing 2 is plugged with spiral shell Line set 3, the inner ring of thread bush 3 is plugged with threaded rod 4, and threaded rod 4 totally two, and two threaded rods 4 are stainless steel material, spiral shell Totally two designs of rasp bar 4 make what thread bush 3 can arrive conveniently in rotation to drive two pieces of No.1 rings by two threaded rods 4 Shape block 6 is mobile, to make this device, it is more convenient to use, and the outside of threaded rod 4 is socketed with nut 5, and nut 5 is close to turntable 1 side and the outside of thread bush 3 mutually overlap, and threaded rod 4 is welded with No.1 ring block 6 far from one end of turntable 1, turntable 1 Top and bottom is welded with bearing bar 7, and bearing bar 7 is welded with stressed plate 8 far from one end of turntable 1, and stressed plate 8 is far from load-bearing The side of bar 7 is welded with No. two ring blocks 9, and the outside of No. two ring blocks 9 is mutually overlapped with the outside of No.1 ring block 6, No.1 ring The quantity of shape block 6 and No. two ring blocks 9 is two, and the top and bottom of two No.1 ring blocks 6 respectively with two No. two Ring block 9 is mutually overlapped close to the side of turntable 1, and No.1 ring block 6 and No. two ring blocks 9 are aluminum alloy material, and No.1 ring The thickness of shape block 6 and No. two ring blocks 9 is five millimeters, this device when in use, by rotating nut 5, and then moves nut 5 It is dynamic to make threaded rod 4 far from one end of turntable 1, to pass through the setting of bearing 2, it can be rotated thread bush 3, pass through thread bush 3 rotation makes thread bush 3 pull threaded rod 4, makes threaded rod 4 drive No.1 ring block 6 mobile to turntable 1, to make No.1 ring Shape block 6 leaves No. two ring blocks 9, is reduced the perimeter of wheel rim composed by No.1 ring block 6 and No. two ring blocks 9, from And make tire that can easily be socketed in the surface of No. two ring blocks 9, after tire socket, opposite direction rotates thread bush 3, makes 4 bar of screw thread drives No.1 ring block 6, overlaps No.1 ring block 6 with No. two ring blocks 9 again, thus opposite direction rotating nut 5, make lateral overlap of the nut 5 again with thread bush 3, to complete the replacement of tire, has this device without professional Operation, can convenient re-type the characteristics of, solve the problems, such as that standard bicycle wheel hub is difficult to re-type, bearing bar 7 Front be welded with stable pipe 10, the two sides for stablizing pipe 10 are plugged with slip pipe 11, and the inside of slip pipe 11 is plugged with stabiliser bar 12, Stabiliser bar 12 is welded far from the one end and No.1 ring block 6 for stablizing pipe 10 close to the side of turntable 1, and stabiliser bar 12 is far from No.1 ring One end of shape block 6 is welded with link block 13, and link block 13 is welded with spring 14 far from the side of stabiliser bar 12, and stabiliser bar 12 is separate One end of No.1 ring block 6 runs through slip pipe 11 and extends to the inside of stable pipe 10, this device when in use, passes through stabiliser bar 12 With the setting for stablizing pipe 10, so that No.1 ring block 6 is merely able to left and right and slided, avoid No.1 ring block 6 in re-type When the case where rotating, to make the reset that No.1 ring block 6 can be more convenient after tire changing of this device, thus The re-type enhanced convenience for making this device keeps this device complete in tire changing by the design of spring 14 and link block 13 Bi Hou, spring 14 is supplied to 13 1 thrusts of link block makes stabiliser bar 12 that can easily push No.1 to push stabiliser bar 12 Ring block 6, and then make the reset enhanced convenience of No.1 ring block 6, keep this device more quick in re-type, surely The two sides for determining 10 inner roof wall of pipe and inner bottom wall offer sliding slot 15, stabiliser bar 12 be located at stablize the top of 10 inner opposite end of pipe with Bottom is welded with slide bar 16, and the one end of 16 back side of slide bar far from stabiliser bar 12 is connected with pulley 17, pulley by shaft 17 outside and the inner wall of sliding slot 15 are slidably connected, the design that the outside of pulley 17 is slidably connected with the inner wall of sliding slot 15, make steady The enhanced convenience that horizontally slips of fixed pole 12, making this device, it is more convenient to use.

Working principle: when in use, by rotating nut 5, and then make mobile make threaded rod 4 far from turntable 1 one of nut 5 End can be rotated thread bush 3 to pass through the setting of bearing 2, by the rotation of thread bush 3, thread bush 3 be made to pull spiral shell Rasp bar 4 makes threaded rod 4 drive No.1 ring block 6 mobile to turntable 1, so that No.1 ring block 6 be made to leave No. two ring blocks 9, makes The perimeter of wheel rim composed by No.1 ring block 6 and No. two ring blocks 9 is reduced, to make tire that can easily be socketed in two The surface of number ring block 9, after tire socket, opposite direction rotates thread bush 3, and 4 bar of screw thread is made to drive No.1 ring block 6, Overlap No.1 ring block 6 with No. two ring blocks 9 again, thus opposite direction rotating nut 5, make nut 5 again with thread bush 3 Lateral overlap has this device and operates without professional to complete the replacement of tire, can convenient re-type Feature solves the problems, such as that standard bicycle wheel hub is difficult to re-type.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
