Abstract

The utility model relates to a spare tire holder for automotive vehicles, comprising support frames which are integrated by bolts; reels are arranged between the support frames by bearings and the shafts of the reels; one end of each shaft of the reed is connected with a worm wheel which and a worm form a movement pair; the worm is provided with a handle bar; the reels are winded with wire ropes; the end head of a wire rope is fixedly provided with a transverse plate whose both ends are provided with projections; one end of a screw bar with two nuts is provided with a handle bar with sockets; the two nuts are fixedly provided with iron hooks. The utility model solves the problems of the existing spare tire holder which is easy to lose deposited spare tires, etc., and can be widely used as a spare wheel tires device for the automotive vehicles.

Description

Spare wheel holder for automotive vehicles

The utility model relates to the automobile-use accessory, particularly the tire spare tyre holder.

At present, the spare tyre holder that the self-propelled vehicle spare tyre uses is by eccentric shaft of rocking-turn, adorning a little external gear on the axle drives a big internal gear and drives sprocket wheel, by iron chains spare tire is sling by the self-locking action that has by two gears later on by the iron chains tire that plays, in case iron chains disconnects or gear has wearing and tearing slightly, just do not have self-locking action tire is lost, depositing spare tyre on self-propelled vehicle is a very difficult thing.

Task of the present utility model realizes as follows: automobile-use tire spare tyre holder comprises the angle-

iron frame

2,7 that fuses by two bolts 3,10, by bearing and winding wheel shaft reel is housed between the support, one end of winding wheel shaft links to each other with worm gear, worm gear and worm screw constitute kinematic pair, crank is housed on the worm screw, be wound with steel rope on the reel, the termination of steel rope is fixed with the transverse slat that two ends have projection, an end that has the lead screw of two nuts on it is equipped with the crank that has jack, is fixed with iron on two nuts and colludes.

The utility model, need only just can be sling tire with very little strength by worm gear, worm drive owing to be provided with bearing at main rotary part; Be provided with the failure-free blocking device simultaneously, two iron collude under the control of screw mandrel the tire steel plate are firmly caught on, and simultaneously, worm gear, worm screw also have self-locking action, and tire can not get loose.

Fig. 1 is the utility model front view;

Fig. 2 is the birds-eye view of Fig. 1;

A most preferred embodiment of the present utility model, as figure, automobile-use tire spare tyre holder comprises two angle-

iron frames

2,7 by bolt 3,10 fuse, pass through bearing 11 between two angle-iron frames, 14 and roll 13 reel 12 is housed, one end of winding wheel shaft links to each other with worm gear 6, constitute kinematic pair with worm gear one worm screw is arranged, crank socket 19 is housed on the worm screw, have the crank jack on the Holder for hand crank and can be used for inserting crank 21, be wound with steel rope 4 on the reel, the termination of steel rope is fixed with the transverse slat 1 that two ends have projection, the effect of projection is to insert in the auxilliary plate of tire tire is sling, and is equipped with one on the spare tyre holder and has two nuts 9 on it, 18 lead screw, an end of lead screw is equipped with the Holder for hand crank 20 that has jack, but assembled cranking bar in the Holder for hand crank hole is fixed with iron on two nuts and

colludes

8,17.

The working process of this device is: when rocking-turn crank 21, the worm drive worm gear makes reel 12 rotation steel ropes 4 that transverse slat is sling the tire steel plate through wheel shaft, be inserted in the 20 screw mandrel crank ways when hanging by crank 21 being extracted behind the last angle-iron frame, the screw mandrel front end is a plus thread, the rear end is a minus thread, and two iron collude outside motion with tire steel plate hook jail when clockwise rotating crank, has just finished the work of tire being hung the jail, crank is unloaded, and screw rod just pins.

Claims

1, a kind of automobile-use tire spare tyre holder, comprise the support that fuses by bolt, it is characterized in that: by bearing and winding wheel shaft reel is housed between the support, one end of winding wheel shaft links to each other with worm gear, and worm gear and worm screw constitute kinematic pair, and crank is housed on the worm screw, be wound with steel rope on the reel, the termination of steel rope is fixed with the transverse slat of two ends band projection, and an end that has the lead screw of two nuts on it is equipped with the Holder for hand crank that has jack, is fixed with iron on two nuts and colludes.
