Description

  The present invention relates to a tire rim structure provided with a spare rim device, and in particular, allows a vehicle to safely travel to a repair site even if the tire is broken by a sharp object or a blade and air leaks or the tire explodes. It is related to a structure that exempts the trouble and danger of driving a car and contributes to the safety of mass driving.

  The tire is a tire that can travel with the outer tire expanded by filling the air with tension. However, when the tire is destroyed by a sharp object and leaks and it becomes impossible to drive, the driver must push the car to the repair place, and when driving at high speed, the destruction of the tire is extremely dangerous. There is a risk of a terrible accident.

  The present invention is provided to solve the drawbacks of the conventional tire described above. The present invention provides a tire rim structure provided with a spare rim device, which reduces the gravity received when assisting with the spare rim device, reduces vibrations formed during assist driving, and improves the smoothness of the assist driving and the bounding of the vehicle. The purpose of this is to design the design so that the structure can be combined with high speed, to increase the assembly efficiency and to contribute to the safety of the general public.

The hooks on both sides and bottom of the two bolt blocks are locked by the locking body, the two bolt blocks are tightly fixed to each other, and the tire and the rim are completely joined together. Preliminary springs characterized in that the spring presses the convex block of the bolt block to form tension, and the locking force of each locking body, locking ring and hook is increased to prevent the situation of separation. It has a rim structure of the tire equipped with apparatus.

  With the structure of the present invention, even if the tire is broken by a sharp object or blade and the air leaks, it can safely travel to the repair site, exempting the trouble of pushing the car, especially with the auxiliary rim device by the auxiliary cushion device It is possible to relieve the gravitational force that is received when the vehicle is running and to reduce the vibrations that are formed during driving assistance, thereby smoothing the driving assistance and reducing vehicle jumping.

  The present invention provides a tire rim structure provided with a preliminary rim device, which binds the rim with a ring frame, and the ring frame is fast-locked by a locking member with two semi-annular frames inserted into each other. The binding surface of the inner circular arc is closely engaged with the unevenness of various rims, and the outer circular arc is fitted with an annular cushion body in the annular cushion groove, and the annular cushion body is connected to the spare rim device. Combine with each other to form a safety tire that can be quickly combined.

  As shown in FIG. 1, the tire rim structure including the preliminary rim device of the present invention includes a ring frame 10, and the ring frame 10 has two semi-annular frames 101 and 101a inserted into each other. As shown in FIG. 2, locking bodies 102 and hooks 103 are provided at both ends of the frames 101 and 101 a, and as shown in FIG. 3, the binding surface 104 of the inner arc is a ring of various rims 60. It is configured to closely engage with the unevenness of the surface, and as shown in FIG. 9, the outer circular arc is formed as an annular cushion groove 105 and the annular cushion body 106 is fitted.

  As shown in FIG. 4, the preliminary rim device 20 is formed by connecting a plurality of tub tube-shaped preliminary rim joint blocks 201 to the perforations 201 a and the perforations 301 of the plurality of coupling bodies 30 in combination with washers 41 and bolts 40. The bolt blocks 202 and 202a are connected in series to the front end and the rear end. As shown in FIGS. 5, 6, and 7, the joint surface of the bolt blocks 202 and 202a is provided with a convex block 202b fitted with a washer 203a and a concave hole 202c fitted therein, and a spring 50 is provided. It has been placed. Hooks 202d and 202g are installed on both sides and bottom of the bolt blocks 202 and 202a, and locking bodies 202e are provided on both sides and bottom hook 202g of the bolt block 202a provided with the recessed holes 202c. The body 202e includes a movable locking ring 21, and the locking ring 21 engages with the hook 202d of the bolt block 202. Further, the locking body 202e is pressed down to engage with the hook 202g of the bolt block 202a. As a result, the two bolt blocks 202, 202a are engaged. Among them, each hook 202d, 202g is provided with an oblique insertion groove 202f. Further, a fitting groove 203 is formed on the upper surface of each spare rim joint block 201 and bolt blocks 202, 202a.

  As shown in FIGS. 8, 9, 11, and 12, one side of the tire 1000 and the rim 60 is coupled first, and the two semi-annular frames 101 and 101 a of the ring frame 10 are inserted into uncoupled openings on the other side. In addition, the rim 60 is surrounded, and the locking bodies 102 and the hooks 103 of the two frames 101 and 101a are engaged, whereby the ring frame 10 tightly binds the rim 60. Further, the annular cushion body 106 is fitted in each preliminary rim joint block 201 of the preliminary rim device 20 and the fitting groove 203 of the bolt block 202, 202a, and further, the locking ring 21 and the locking body on both sides and the bottom of the bolt block 202a. 202e locks the hooks 202d and 202g on both sides and the bottom of the two bolt blocks 202 and 202a, so that the two bolt blocks 202 and 202a are engaged with each other and tightly bound and fixed, and the tire 1000 and the rim 60 are completely joined together. . Among them, the spring 50 in the concave hole 202c of the bolt block 202a presses the convex block 202b of the bolt block 202 to form a tension, thereby increasing the locking force of each locking body 202e, the locking ring 21, and the hooks 202d, 202g. To prevent the situation of withdrawal.

  As shown in FIG. 10, when the spare rim device 20 is to be repaired, it can be easily and smoothly engaged by inserting screwdrivers into the slant insertion grooves 202f of the hooks 202d and 202g on both sides of the bolt blocks 202 and 202a and the bottom. The stop body 202e and the locking ring 21 are pushed to be detached from the hooks 202d and 202g, and can be quickly removed.

  As shown in FIG. 13, when the tire 1000 is destroyed, the vehicle body can be supported by the spare rim device 20 and operated to a repair shop, and there is no difficulty in pushing the vehicle, and life safety can be ensured. Among them, the annular cushion body 106 reduces the gravity received when the auxiliary rim device 20 assists traveling and the vibration formed when assisting the traveling, smoothes the traveling and assists the vehicle bounce.

  As described above, the present invention has the effect of ensuring the safety of operation with rapid assembly.
