Description

For dismantling the withdrawing device of motor cycle tire and wheel hub

Technical field

The utility model relates to a kind of withdrawing device, more precisely a kind of for dismantling the withdrawing device of motor cycle tire and wheel hub.

Background technology

Adopting two disengaging bar separated tyres that are mutually rotationally connected and wheel hub is the separating tool of a kind of very common separated tyre and wheel hub, but because the resistance running into when the rotating separation bar is larger, the diameter of disengaging bar or thickness are generally larger, the structure that available technology adopting is staggeredly arranged two disengaging bars makes disengaging bar in rotation, in horizontal surface, be subject to force unbalance, tire is easily swung up and down, and experience is poor.

Utility model content

The utility model is mainly to solve the existing technical matters of prior art, thereby provide a kind of employing to deter groove structure, make the first arm and the second arm in same level, stress balance in horizontal surface, when this second arm of rotation, tire is difficult for swinging up and down, simultaneously, with position-limited lever, can avoid the first arm and wheel hub to relatively rotate, lock out operation convenient for dismantling the withdrawing device of motor cycle tire and wheel hub.

Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:

A kind of for dismantling the withdrawing device of motor cycle tire and wheel hub, comprise a center shaft, one first arm and one second arm, the first described arm and the second described arm and described center shaft are rotationally connected, the first described arm comprises one first horizontal part and one first rake, and the second described arm comprises one second horizontal part and one second rake.

As the utility model preferred embodiment, the first described arm also comprises a position-limited lever, and described position-limited lever is connected with the below of described the first horizontal part.

As the utility model preferred embodiment, the second described arm also comprises that one deters groove, and the described groove that deters runs through described the second horizontal part and horizontal arrangement, and the described width that deters groove equates with the height of the first described horizontal part.

As the utility model preferred embodiment, described also comprises two separating heads for dismantling the withdrawing device of motor cycle tire and wheel hub, and two described separating heads form detouchable with the end of described the first rake and described the second rake respectively and are connected.

Of the present utility modelly for dismantling the advantage of the withdrawing device of motor cycle tire and wheel hub, be: adopt and deter groove structure, make the first arm and the second arm in same level, stress balance in horizontal surface, when this second arm of rotation, tire is difficult for swinging up and down, simultaneously with position-limited lever, can avoid the first arm and wheel hub to relatively rotate, lock out operation is convenient.

The specific embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.

As shown in Figure 1 and Figure 2, a kind of for dismantling the withdrawing device of motor cycle tire and wheel hub, comprise a center shaft 1, one first arm 2 and one second arm 3, this first arm 2 and this second arm 3 are rotationally connected with this center shaft 1, this first arm 2 comprises one first horizontal part 21 and one first rake 22, and this second arm 3 comprises one second horizontal part 31 and one second rake 32.In use this center shaft 1 is connected with the wheel hub center of a bike wheel, the end of this this first rake 22 and this second rake 32 is inserted in the middle of wheel hub and tire, along the center of this center shaft 1 this first arm 2 of rotation or this second arm 3 one week, wheel hub and tire were separated.

As shown in Figure 1, Figure 2, Figure 3 shows, this first arm 2 also comprises a position-limited lever 23, and this position-limited lever 23 is connected with the below of this first horizontal part 21.In use, one end of this position-limited lever 23, through the blank space on this wheel hub, can be placed restrictions on this first arm 2 and relatively rotate with wheel hub.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, this second arm 3 also comprises that one deters groove 33, and this deters groove 33 and runs through this second horizontal part 31 and horizontal arrangement, and this width that deters groove 33 equates with the height of this first horizontal part 21.Arrange this deter groove 33 can make this second horizontal part 31 with this first horizontal part 31 in same plane, stress balance, and make the end of this first rake 22 and the end of this second beveled end 32 can close proximity, what can make that the end of this second rake 32 can be complete rotates a circle around wheel hub, and separating effect is better.

As 1, as shown in Fig. 2, Fig. 5, should also comprise two separating heads 4 for dismantling the withdrawing device of motor cycle tire and wheel hub, these two separating heads 4 are connected with the end composition detouchable of this first rake 22 and this second rake 32 respectively.This separating head 4 respectively with this first rake 22 and these minutes two rake 32 end adopt split-type design, after this separating head 4 is worn, change more convenient, be unlikely to change whole the first arm 2 or the second arm 3, use cost is lower, split-type design can also be selected separately high-abrasive material for separating head 4 simultaneously, productive costs is lower, and the separating head 4 that can also be equipped with plurality of specifications to be suitable for the tire of various models simultaneously.

Below only with an embodiment, mentality of designing of the present utility model is described, in the situation that system allows, the utility model can expand to external more functional module simultaneously, thereby expands to greatest extent its function.

The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
