Description

TECHNICAL FIELD

[0001] The utility model relates to a tire technical field especially relates to a tire inner support locking structure. BACKGROUND

[0002] In order to improve the safety of tire, generally installs the inner support body on the rim of tire, to realize that the vehicle can still drive safely for a distance after tire burst.

[0003] The current inner support body generally includes three support body bodies of annular splicing, and the adjacent two support body bodies are connected through the locking structure. For example, the patent with publication number CN209521491U discloses a tire inner support device, and the locking structure includes front and rear lugs that are superimposed, a wedge-shaped sliding block and two bolts. When using, first, the wedge-shaped sliding block and the rear lug are locked and connected through the first bolt, so that the inner support body is tightened in the circumferential direction to tightly hold the rim. Then, the front lug and the rear lug are locked and connected through the second bolt. However, since the locking operation needs to be performed inside the tire, the operation space is small, the installation is inconvenient, and the efficiency is low. SUMMARY

[0004] The utility model aims at providing a tire inner support locking structure, which can effectively solve the problems of inconvenient installation and low efficiency.

[0005] To achieve this purpose, the utility model adopts the following technical scheme:

[0006] A tire inner support locking structure is used for locking and connecting two adjacent support body bodies. The tire inner support locking structure includes a lock ring and a lock block. One end of the lock ring is locked and connected with the first support body body through a first locking assembly. The other end of the lock ring is slidingly arranged in the second support body body. The lock block is slidingly arranged in the second support body body and is slidingly matched with the inner side of the lock ring through a slope. The lock block is locked and connected with the second support body body through a second locking assembly.

[0007] Further, the second support body body is provided with a sliding groove in a direction parallel to the central axis thereof. One side of the lock block is in sliding contact with the sliding groove. A lock ring groove is formed in one side of the sliding groove in sliding contact with the lock block. The lock ring is slidingly arranged in the lock ring groove.

[0008] Further, the second locking assembly includes a second bolt and a second nut. The second nut is fixedly connected with the second support body body. One end of the second bolt passes through a through hole formed in the lock block and is screwed with the second nut.

[0009] Further, the through hole is provided with an internal thread.

[0010] Furthermore, the second bolt is provided with an anti-loosening locking plate.

[0011] Furthermore, the first support body has a slot for inserting one end of the locking ring.

[0012] Furthermore, the first locking assembly includes a first bolt and a first nut screwed to the first bolt.

[0013] Furthermore, washers are provided at both ends of the first bolt.

[0014] The beneficial effects of this utility model are as follows: The tire internal support locking structure of this utility model utilizes a first locking assembly to lock the connecting lock ring and the first support body, and a second locking assembly to connect the locking block and the second support body. By driving the locking block to slide relative to the second support body, the locking ring slides, thereby tightening the two adjacent support bodies to grip the rim. Using this tire internal support locking structure, it is possible to first pre-fix and connect the three support bodies into a ring-shaped internal support body, and then place the ring-shaped internal support body into the tire for tightening. This makes installation more convenient, facilitates mass assembly installation, and offers high installation efficiency and easy maintenance. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of a tire internal support locking structure provided by this utility model. Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, a tire internal support locking structure is used to lock and connect two adjacent support bodies 1. The tire internal support locking structure includes a locking ring 4 and a locking block 7. One end of the locking ring 4 is locked to the first support body 1 via a first locking assembly, and the other end of the locking ring 4 is slidably disposed within the second support body 1. The locking block 7 is slidably disposed within the second support body 1 in a direction perpendicular to the sliding direction of the locking ring 4, and slides in cooperation with the inner side of the locking ring 4 via an inclined surface. The locking block 7 is locked to the second support body 1 via a second locking assembly.

[0018] Specifically, the first support body 1 has a slot 2 for positioning and inserting one end of the locking ring 4. The first locking assembly is used to fix the locking ring 4 in the slot 2. In this embodiment, the first locking assembly includes a first bolt 3 and a first nut 10 screwed to the first bolt 3. Further, washers 11 are provided at both ends of the first bolt 3.

[0019] In the embodiment, the second support body 1 is provided with a sliding groove 8 in a direction parallel to the central axis, and the lock block 7 is in sliding contact with the sliding groove 8 on one side, and the sliding groove 8 is provided with a lock ring groove on the side in sliding contact with the lock block 7, and the lock ring 4 is slidingly arranged in the lock ring groove.
