Technical Field

The invention belongs to the technical field of vehicle safety tires, and particularly relates to an independent locking mechanism of a safety tire supporting device, which mainly relates to a connecting structure and a locking structure form of the supporting device.

Background

The safety tire means that the vehicle tire can still continue to run for a long distance after being attacked or accidentally decompressed and deflated, and the good control stability and running stability of the vehicle are ensured. The supporting device is used as a main functional component of the safety tire, protects the safety of a vehicle when the tire is suddenly decompressed, and ensures that the vehicle can continuously run for a long distance under the zero-pressure state of the tire. The supporting device is arranged in the tire and fastened on the rim, under the normal condition of the tire pressure of the tire, the supporting device cannot loosen and slip relative to the rim, the normal use of the vehicle tire cannot be influenced, and the supporting device is required to replace the tire to bear weight when the vehicle tire is subjected to accidental pressure loss, so that the vehicle can continuously run. For the field of special vehicles using safety tires, the driving road surface is complex, including good pavement road surfaces, cross-country road surfaces such as gravel, mountain land, ice and snow, cultivated land and the like, and reinforced road surfaces of irregular terrains such as roadblocks, roadways, convex ridges and the like, the connection part of the supporting device is required to be more reliable, and the connection part cannot be loosened or failed due to long-term work of the vehicle, so that the aims of protecting the safety of the vehicle and continuously driving the vehicle after the vehicle tire is decompressed are fulfilled.

Disclosure of Invention

The invention provides an independent locking mechanism of a novel safety tire supporting device, and solves the technical problems that the locking mechanism of the safety tire supporting device in the prior art cannot be completely locked and is easy to loosen and fall off.

In order to achieve the purpose, the specific technical scheme of the invention is as follows: an independent locking mechanism of a safe tire supporting device comprises a locking connecting piece and a locking connecting assembly, wherein the locking connecting piece comprises a first flange face chute bolt, a first tooth-type anti-loosening locking sheet and a locking inclined block; the locking and connecting assembly comprises a second flange face chute bolt, a second tooth-type anti-loosening locking sheet and a gasket; the first safe tire supporting device body joint of the safe tire supporting device is provided with 2 connecting bolt holes, the second safe tire supporting device body joint is provided with an inclined slotted hole and a fastening hole, and the inclined slotted hole is in a long hole shape and can accommodate a first flange face inclined slot bolt to slide along the length direction of the inclined slotted hole; the fastening hole is also in a long hole shape and can accommodate the second flange face chute bolt to slide along the length direction of the fastening hole; a locking inclined plane which can correspond to the inclined plane of the locking inclined block is formed at the upper end of the inclined groove hole; the locking and connecting assembly is inserted into a fastening hole on the joint of the second safe tire supporting device body and a first connecting bolt hole arranged on the joint of the first safe tire supporting device body and is used for locking and connecting the joint of the first safe tire supporting device body and the joint of the second safe tire supporting device body; the locking connecting piece is inserted into the inclined groove hole and the second connecting bolt hole, and the first safety tire supporting device body joint and the second safety tire supporting device body joint are fixedly connected.

Further, first safe tire strutting arrangement body connects for modified nylon, and it has the connecting block still to wrap up in the first safe tire strutting arrangement body connects, is provided with on the connecting block with first connecting bolt hole and the corresponding two screw holes in second connecting bolt hole position.

Furthermore, the gasket is H-shaped, and a gasket sliding groove for accommodating sliding of the gasket is arranged on the fastening hole in the joint of the second run-flat tire supporting device body.

Furthermore, the bolt cap of the first flange face chute bolt and the bolt cap of the second flange face chute bolt are respectively provided with 6 clamping grooves, the joint of the second safety tire supporting device body is provided with a sliding groove, the first tooth-type anti-loosening locking piece and the second tooth-type anti-loosening locking piece are respectively provided with 4 clamping teeth, and the width of each clamping groove is larger than that of each clamping tooth.

Furthermore, the locking inclined block is in clearance fit with a locking inclined plane on the joint of the second safe tire supporting device body, and the angle of the inclined plane is 45 degrees.

Furthermore, the first tooth-type anti-loose locking piece is symmetrically provided with two clamping angles for clamping and fixing the locking inclined block; the second tooth-type anti-loosening locking piece is symmetrically provided with two clamping angles for clamping the gasket; the clamping angle clamping depth is smaller than the thickness of the gasket, and the width is smaller than the width of the locking inclined block.

Compared with the prior art, the invention has the beneficial effects that: the connecting parts of the safe tire supporting device are respectively connected, fastened and locked by the locking assembly and the locking and connecting assembly, the two sets of assemblies are mutually independent and have double insurance, after one of the assemblies is loosened, the other assembly can still lock the other assembly, and the locking and connecting assembly also can simultaneously slide relatively to lock the assemblies while locking and reinforcing the locking assembly, after the fastening is finished, the latch of the tooth-type anti-loosening locking piece is pried and clamped into the clamping groove of the chute bolt on the flange surface, so that the locking purpose is achieved, the locking effect is better, and the safe tire supporting device is more effectively prevented from loosening and falling off; through the clearance fit on locking sloping block and locking inclined plane to fastening effect is better in fastening process, only needs through adjusting flange face chute bolt, realizes fastening and not hard up to safety tire strutting arrangement with regard to accessible locking sloping block, and it is fastening the back, and is also better to safety tire strutting arrangement's locking effect, and life is longer.
