Abstract

The utility model relates to a machine for removing an outer cover of a tyre, which is composed of an upper and a lower gantries, a worm rod, a worm gear, a screw rod, prying claws, a cross bolt, etc. By using the upper and the lower gantries, the prying claws, a hand handle, the worm rod and the worm gear, the upper gantry is driven to move downwards along the screw rod. The upper and the lower gantries axially press the outer cover to remove downwards from a wheel felloe, and the prying claws tightly claw the wheel felloe and are inserted like wedges along the radial direction of the wheel felloe. After the upper ends of the prying claws are tightly attached to gantry posts, the prying claws axially press and remove the outer cover from a major rim of the wheel felloe, which achieves the purpose of removal. The utility model has the advantages of reasonable design, simple structure, safety, labour saving and rapidness. The utility model is a portable tool which can be used together with an air inflating machine. The utility model is not limited by fields and is especially suitable for roadside tyre repair shops and removing an outer cover for a medium-sized vehicle or a vehicle larger than the medium-sized vehicle. When operated in open air, the utility model shows more advantages.

Description

The car wheel covering demountor

The utility model belongs to a kind of car wheel covering demountor.

At present, generally be to add sledgehammer removing vehicle tyres cover tire with chock, except some dollies have the car wheel covering demountor, still there is the above car wheel covering demountor of suitable in-between car at the end, and 95225525.1 1 kinds of novel tires of patent load and unload device, patent 95223077.1 high-mobility, multipurpose, wheeled vehicle wheel tire press, patent 99200365.2 self-propelled vehicle device for taking off tyre etc., and structure is complicated, cost is higher, use not more conveniently, and be subjected to field boundary ground restriction, should not promote the use of.

The purpose of this utility model provides a kind of car wheel covering demountor, utilize upper and lower gantry, sled pawl and wind, worm screw, worm gear, the upper and lower gantry of drive to move down along screw rod, and axially oppress by upper and lower gantry, order sled pawl pawl bearing up pulley rim also radially inserts as the chock, after sled pawl upper end is adjacent to column, the axial compression again of sled pawl is peeled off the big edge of wheel rim with tire, to reach the purpose of dismounting.

The utility model is by last, following gantry, worm screw, worm gear, screw rod, the sled pawl, compositions such as horizontal bolt, last gantry is made up of last Long Menliang (6) and two last columns (7), through hole is arranged in the middle of the last Long Menliang (6), two Ka Jiao are equipped with on following through hole side, respectively there are two translots at last Long Menliang (6) two ends, there are two bolts and nuts last column (7) upper end, can in the translot of last Long Menliang (6), move, there is sled pawl seat last column (7) lower end, sled pawl (10) is contained on the sled pawl seat, sled pawl (10) can rotate around the axle of sled pawl seat, sled pawl (10) two ends are the chock shape, it is capable that the following end of last Long Menliang (6) is provided with zig-zag row tooth 10-15, it is capable that last column (7) upper surface is provided with the capable tooth 2-3 that matches with last Long Menliang (6), following gantry is by Long Menliang (12) and two following columns (13) are formed down, other structures are identical with last gantry, just Ka Jiao be contained in down gantry above, last gantry is blocked the location with following gantry by Ka Jiao, make, following gantry together with screw rod (11), packing ring (4), worm gear (2), nut (1) links, there is horizontal bolt seat screw rod (11) lower end, horizontal latching (14) links with horizontal bolt (15), can on worm screw (11) outward flange, load onto wind, also can use gantry separately.

The utility model is reasonable in design, and is simple in structure, is a kind of hand-held tool, can cooperate air inflating machine for dismantling tyre to use, safe, laborsaving, quick, be not subjected to the restriction of field boundary ground, be particularly suitable for the above tire dismantling of roadside tire patching shelves and in-between car and use the more apparent advantage of rainy day operation in the open.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model running condition figure.

In the utility model, except that nut, screw rod, worm screw, worm gear can be bought, all the other all available steel processed, and by assembling shown in Figure 1, just can use.Horizontal bolt is used for radially interting into the louvre of flat slumber-coach wheel wheel rim, and screw rod is fixed by horizontal latching, shaking wind moves down along screw rod by gantry on worm screw, the worm gear drives, and break away from wheel rim downwards by the axial lower compression tire in upper and lower gantry, sled pawl pawl bearing up pulley rim also radially inserts as the chock tire is peeled off the big edge of wheel rim to reach the dismounting purpose, and as shown in Figure 2, a is a sled pawl initial condition, b is a sled pawl final state, and c is that tire is peeled off state.Following gantry is for portable light, root a tree name situation and deciding, can use gantry separately, unclamp the nut of bolt on the column, bolt can move in the translot on the beam of upper and lower gantry, just can regulate the position of column under the beam of gantry by the wheel rim diameter, be applicable to the tire dismantling of various vehicles.The utility model can replace current adding the method for sledgehammer remove a tyre with chock, and both safety was laborsaving again, did not damage tire and nave boss when remove a tyre.
