Abstract
The utility model discloses a tyre detaching device which is composed of a screw rod, a screw nut sheathed on the screw rod, a press ring and a supporting dist. The press ring is composed of four parts hinged with one another. Number of arc-shaped arms is four. Two opposite arc-shaped arms are movable arc-shaped arms. At least three telescopic supporting legs are arranged at lower part of the round supporting disc. Gasket rings are arranged at lower end of the telescopic supporting legs. Since the utility model adopts screw rod downwards press principle to press an outer tyre downwards so as to release interlocking force between the tyre and a fastening ring, the utility model has the advantages of convenient operation, short time, low labor load, and improved safety. The device is easy to carry after being detached and is the most suitable tool for detaching tyre.
Description
The utility model relates to a kind of tyre dismounting device.
At present, the tyre dismounting of some large-scale carriers all is 5 * 5 angle bar of looking for a 50-80 millimeter, is placed on tire and wheel rim junction, be placed on the lower edge of snap ring, knock with sledgehammer, the method that cover tire is moved down realizes, its shortcoming is that the dismounting effort easily causes tire impaired.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of tyre dismounting device that is easy to dismounting and is difficult for tire is caused damage is provided.
The purpose of this utility model is achieved in that the tyre dismounting device is made up of screw mandrel, the screw, pressure ring, the pallet that are socketed on the screw mandrel, it is characterized in that, goes back on described screw that fixed cover is equipped with ratchet and head is
Shape pull arm, pulling arm
Be provided with vertical pivot in the shape head, be connected with the transmission tooth on the vertical pivot, described vertical pivot head end passes pulls arm
The shape head-bent forms transmission tooth handle, described transmission tooth and described ratchet interlock, described screw bottom is provided with annular convex shoulder, be crimped with pressure bearing in the annular convex shoulder bottom, the outside at pressure bearing is fixedly connected with steady ring, steady ring is captiveed joint with pressure ring by arched arm, is provided with round tray at described screw mandrel lower end, and described round tray is connected with screw mandrel by the tapped bore of central authorities.
As a kind of improvement of the present utility model, described pressure ring is that four parts that are hinged are formed, and the number of described arched arm is 4, wherein has relative two to be the adjustable arc arm, described adjustable arc arm termination and pressure ring are hinged, another termination of adjustable arc arm and knock hole clamping.
As another improvement of the present utility model, described round tray bottom is provided with at least three telescopic outriggers, is provided with gasket ring in the lower end of described telescopic outrigger.
Because the utility model tyre dismounting device adopts screw mandrel roof pressure principle that cover tire is pressed down, and has removed the interlocking power of tire and snap ring, easy to operate, time saving and energy saving, improved safety factor, and after this device disassembled, being easy to carry about with one, is the optimal instrument of present tyre dismounting.
Fig. 1 is a tyre dismounting apparatus structure scheme drawing.
Fig. 2 shows scheme drawing for the tyre dismounting device cuts open.
Below in conjunction with accompanying drawing the utility model is described in further detail, the tyre dismounting device is provided with annular convex shoulder by screw mandrel 1, the bottom with wire rod thread bonded assembly screw 7, screw 7 that is socketed on the screw mandrel 1, having with the termination of screw 7 at annular convex shoulder is the pressure bearing 14 of axle, the periphery of pressure bearing 14 is fixedly connected with steady ring 15, steady ring 15 is connected with the pressure ring 16 that with screw mandrel 1 is the axle center by four arched arms 10, and the vertical section is that step-like round tray 11 is connected with screw mandrel 1 lower end by central tapped bore.Go back on described screw 7 that fixed cover is equipped with ratchet 3 and head is
Shape pull arm 9, pulling arm 9
Be provided with vertical pivot in the shape head, be connected with transmission tooth 8 on the vertical pivot, described vertical pivot head end passes pulls arm 9
The shape head-bent forms transmission tooth handle 2, described transmission tooth 8 and described ratchet 3 interlocks.Described pressure ring 16 is formed for four parts that are hinged, and described arched arm 10 wherein has relative two to be adjustable arc arm 4, and described adjustable arc arm 4 terminations and pressure ring 16 are hinged, another termination of adjustable arc arm 4 and knock hole 5 clampings.Described round tray 11 bottoms are provided with at least three telescopic outriggers 12, are provided with gasket ring 6 in the lower end of described telescopic outrigger 12.Operating process is: rotate transmission tooth handle 2, make transmission tooth 8 and ratchet 3 sting and, arm 9 is pulled in rotation, ratchet 3 drives screw 7 and rotates, screw 7 convex shoulder down force pressure bearings 14, drive pressure ring 16 by steady ring 15, arched arm 10,4 and press down tire, pallet 11 ejects wheel hub with respect to moving on the pressure ring 16.Its installation process is placed on the tire bottom with wheel hub and gets final product.Not the time spent, each parts can be pulled down, adjustable arc be pulled arm 4 pull down, be stuck on the knock hole 5, pivotally attached pressure ring 16 is folding, so that carry.
