Once the spare tyre is hanging against the bottom of the support body, the safety bolt is tightened on the support body by locking nuts. The utility model has a simple structure, a firm entirety and an easy use, and plays an effective role of antitheft.
Description
Affiliated field: the utility model relates to the antitheft suspension holdfast of motor vehicle spare wheel tire.
Background technology: automobile spare tire does not have the purpose made latching device usually in the prior art, though spare tyre can be hung between two crossbeams by spare tyre crank and cope down frame, but this method can't be locked at spare tyre on the vehicle body safely and reliably, thus lose often, stolen situation.
Summary of the invention: at above-mentioned the deficiencies in the prior art part, the utility model provides a kind of motor vehicle spare wheel tire antitheft suspension holdfast, it is simple in structure, integral body is firm, easy to use, can effectively play antitheft effect.
The utility model reaches by following technical measures: it comprises the stake body that links to each other with car chassis, the steel cable of lifting spare tyre, the parts such as kinematic pair that worm and gear constitutes, it is characterized in that: have a spare tyre that links to each other with stake body to hang body, spare tyre is hung the kinematic pair that reel that the coiling steel cable is housed in the body and worm and gear constitute, the steel cable other end that is wound on the reel is connected with holder tire plate, holder tire plate two ends respectively are fixed with a shear bolt, in case spare tyre hangs when leaning on to the stake body bottom surface, by locking nut shear bolt is fastened on the stake body.
Described stake body is structure as a whole or connects into removable structure with the bolt nut fastener by being welded to connect with angle bar spare, and body hung by the spare tyre that reel and worm and gear be housed and angle-iron frame is weldingly connected.
Described reel can be an also solid axle of hollow wheel tube, the other end captive joint worm gear of reel or axle.
Described worm screw stretches out spare tyre and hangs the sleeve that an external end is made the insertion of confession crank, and the fixedly through hole of crank is arranged on the sleeve, in the crank insertion end dead ahead of sleeve one guide cylinder that is connected on the stake body 7 is arranged.
Described spare tyre is hung the worm and gear installed in the body and is enclosed in the box body with cover cap with the coaxial reel of worm gear, and cover cap is fastening with box body usefulness spiral nail.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side schematic view of Fig. 1.
Fig. 3 hangs the structure cut-away view of body for the spare tyre among Fig. 1.
The specific embodiment is described further in conjunction with the accompanying drawings.
As shown in the figure, the antitheft suspension holdfast of the spare tyre that the utility model provides have one by two slotted-angle shelvings 1 by last sheer pole 9, also can become structure easy to assemble between 7 support bodys that are welded, last sheer pole and slotted-angle shelving, be convenient to the packed and transported of the antitheft suspension holdfast of tire by bolted connection; Be installed with spare tyre by screw 13 between two slotted-angle shelvings and hang body 2, spare tyre is hung reel 11, worm gear 10 and worm screw 8 is housed in the body, one end of winding wheel shaft links to each other with worm gear is coaxial, and is fixed on spare tyre and hangs on the body, and worm screw stretches out spare tyre and hangs the sleeve that an external end is made, the fixedly through hole of crank is arranged on it, one guide cylinder 12 is arranged on the stake body 7 of barrel forward end, on the crank through hole is arranged, have 20cm at interval between sleeve and the guide cylinder, so that worm screw is flexible, worm screw is a plus thread; Be wound with steel rope 6 on the reel, another termination of steel rope is connected with the holder tire plate 5 of two ends strap bolt 4, and bolt 4 orders at holder tire plate two ends are tightened with jam nut 3 after passing screw and the through hole on the two slotted-angle shelving bases on the spare tyre wheel rim.
During use, spare tyre is clamped between holder tire plate and the stake body bottom surface, crank is inserted in the sleeve of guide cylinder and worm screw one end, cw changes crank, the worm drive worm gear, the coaxial reel that links to each other of drive and worm gear rotate and with sagging steel rope in race, steel rope lower end tension holder this moment tire plate 5 is tightly asking spare tyre upwards to sling, when hanging by to the angle-iron frame bottom surface time, transfer to crank, because worm gear, worm screw has self-locking action, thereby the conter clockwise reversing can not occur with the coaxial reel of worm gear, jam nut is tightened with the bolt at holder tire plate two ends to be fixed on the angle-iron frame again, reach double insurance, promptly finish the spare tyre process that hangs.
Spare tyre is hung the worm and gear installed in the body and is enclosed in the box body with cover cap with the coaxial reel of worm gear, and cover cap is fastening with spiral nail with box body, operates the attempt of loading and unloading or pilferage spare tyre without authorization to prevent other people.When needs use spare tyre, unclamp and holder tire plate bolts at two ends bonded assembly nut, crank is inserted in conter clockwise driving in guide cylinder and the worm screw one end sleeve through hole, spare tire just can drop to ground safely, finishes taking of spare tire.
The utility model compared with prior art, have simple in structure, be convenient to install, solid and reliable, operation spirit Live, the lifting of loading and unloading spare tyre is quick, hang stablize firm, long service life and have self-locking skidproof, anti-theft feature etc. concurrently Characteristics, this device has alleviated labour intensity, has shortened the time of loading and unloading spare tires, has simultaneously anti-theft function. And And volume is little, cost is low, is the practical anti-theft device for spare tire of insurance, is convenient to popularize.
