Abstract

The utility model relates to a holder for a screw sleeve used for dismounting a tyre. The utility model is especially used for dismounting a vehicle tyre, and is composed of an inner telescopic sleeve, an outer telescopic sleeve and a corresponding positioning and locking mechanism, nut and a screw bolt which are arranged at the upper section of the inner sleeve, and a support at the top end of the screw bolt. The coarse adjustment of the height of the holder is realized by that the sleeve is stretched to be locked; the fine adjustment of the height of the holder is realized by that the screw bolt is rotated; the screw sleeve is supported by the U-shaped support at the top end. With the holder, the screw sleeve can be used for dismounting the tyre by one man operation with convenience and labor saving, and does not twist or press the screw to be broken.

Description

Tyre dismounting screw socket holder tool

The utility model relates to vehicle maintenance and repair, and relates generally to the motor tire dismantling devices, specifically is meant a kind of motor tire dismounting screw socket holder tool.

In the prior art, dismounting motor tire (also comprising other truck conspicuity marking air-inflation tyre), all adopt special tool---screw socket, during the dismounting tire, sleeve one end (end of band spiral shell side endoporus) is placed in tire to be carried on the back on the tight screw, the sleeve other end is inserted whippletree, pressing changes the whippletree rotational sleeve, and screw is unloaded or tightens, and weak point is, with defeating when changeing whippletree, one end of the slotting whippletree of sleeve just is depressed and inclines, and so, very easily screw is turned round and is pressed bald side, and people's dismounting tire is extremely required great effort, and gives long-distancely to go out car and cause very big inconvenience.

Goal of the invention of the present utility model provides a kind of tyre dismounting screw socket holder tool, when the dismounting tire, holds screw socket with this holder tool, makes the dismounting operation both laborsaving, can not make the bald side of screw again.

Summary of the invention of the present utility model is, a kind ofly is exclusively used in the tyre dismounting screw socket holder tool that the motor tire dismounting is used, be characterised in that, by telescopic sleeve, nut on it and screw rod, and " U " shape holder (9) three parts of screw tip constitute; Sleeve comprises the outer sleeve (2) of band base (1) and is placed in inner sleeve (6) in it, and outer sleeve has vertical openings (3), on one side it has horizontal bayonet socket (4), the inner sleeve bottom is welded with locking teeth (5) admittedly, can be stuck in the bayonet socket (4) of outer sleeve; Inner sleeve top is one section tapped nut (7), is equipped with screw rod (8) in it.

The utility model can not establish vertical openings and horizontal bayonet socket on outer sleeve, but corresponding lock hole (10) before and after establishing or not locking teeth (5) on the inner sleeve, and corresponding lock hole (11) before and after establishing; If plug (12) passes the lock hole of inside and outside sleeve and plays locking action.

Another design plan of the present utility model is that to change the sleeve telescopic construction be that single screw rod is regulated structure, and it is by tapped screw sleeve (2), screw rod (3) of assembling in it, and " U " shape holder (4) that is welded in screw tip admittedly constitutes.

Fig. 2, the utility model adopt regularly partial schematic diagram of plug-inserting lock.

Fig. 3, the utility model screw rod adjustable type front view.

Below, in conjunction with the accompanying drawings the utility model is elaborated.

As shown in Figure 1, tyre dismounting screw socket holder tool, it is a telescopic tube-in-tube structure, it is by sleeve, nut on it and screw rod, and holder three parts of screw tip constitute, the cover letter comprises inner sleeve (6) and outer sleeve (2), it is provided with the stretching blocking device, is the both sides of a side or the symmetry of sleeve wall outside, opens vertical openings about in the of (3), several horizontal bayonet sockets (4) are opened on one side of opening, in the both sides of inner sleeve barrel bottom one side or symmetry, admittedly weld locking teeth (5), its diameter is slightly less than the width of vertical openings and the height of horizontal bayonet socket, with the inner sleeve up-down stretch, slightly rotation can be stuck in locking teeth (5) in the bayonet socket (4), makes the inside and outside sleeve position and lock of stretching.When blocking device was located at barrel one side, its vertical openings, laterally the size of bayonet socket and locking teeth should be more greatly, to satisfy the support load requirement, when being located at the barrel both sides, size can be littler, can satisfy the support load requirement, and upright stable, so general both sides are provided with.Laterally bayonet socket (4) can only be opened severally at the epimere of vertical openings, opens one in the bottom, and the several bayonet sockets of epimere are to be the regulating sleeve height usefulness that stretches, and one of bottom is to lock when drawing for sleeve to be convenient to placement.Blocking device also can not established opening, bayonet socket and locking teeth, but on the inside and outside sleeve wall, bore hole, garden (10), (11) that several see through front and rear wall, front and rear gaps is symmetrical in an axle center, one plug (12) is set again, inner sleeve is pulled out, the hole of alignment inside and outside sleeve is plugged plug (12) and is got final product (as shown in Figure 2).Bayonet socket form blocking device, one draws one to change and to get final product, and plug form blocking device draws back aligned hole and plugs plug and get final product, and the two is all very convenient.The stretching locking of inside and outside sleeve is to carry out coarse adjustment for the height that holds in the palm tool, fine tuning is to realize by screw rod, be provided with negative thread at the inner sleeve epimere, also a nut (7) can be soldered to the inner sleeve top admittedly, in nut, assemble screw rod (8), realize the height fine adjustment by rotary screw, screw tip is provided with the holder of " U " shape, can weld one admittedly, also can install one by engage thread, " U " shape is held the screw socket effect.When this holder tool uses, the flexibility locking, rotary screw again, it is suitable to regulate height, holds screw socket, can carry out the dismounting operation.

Another design plan of the present utility model, be single screw rod adjustable type, it has the screw sleeve (2) of a band base (1), is equipped with screw rod (3) in it, and screw tip is welded " U " shape holder (4) admittedly, during use, the turn screw rod is regulated and is highly got final product, and its deficiency is to revolve screw rod and regulate highly time-consuming longer, size during gathering is greater than sleeve-type, and processing capacity is bigger.

The utility model has had this holder tool for dismounting tire screw sleeve provides a convenient and practical holder tool, when re-using screw socket dismounting tire, gets final product one man operation, and is convenient and strength-saving, is unlikely extremely screw turned round to press bald side.
