The threaded block is connected to the air intake device, and the rear end of the threaded block is fixedly connected to the air nozzle inner tube.

[0013] Furthermore, the air nozzle inner tube is connected to the air intake device.

[0014] Further, the intake device includes a movable rod, a sealing block, a baffle, a spring, a limiting rod, an L-shaped limiting chute and a slot. A slot is provided at the front end of the threaded block, and a pair of L-shaped limiting chutes are provided on the inner wall of the inner tube of the air nozzle. A baffle is fixedly connected to the inner wall of the rear end of the inner tube of the air nozzle. One end of the spring is fixedly connected to the upper end of the baffle, and the other end of the spring is in contact connection with the limiting rod. The limiting rod is slidably connected in the L-shaped limiting chute. A movable rod is fixedly connected to the inner wall of the limiting rod.

The inner walls of the locking grooves are in one-to-one snap connection with the T-shaped anti-detachment blocks.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. In the present utility model, the inner tube of the air nozzle and the threaded block of the air nozzle device of the air nozzle assembly are inserted into the outer tube of the air nozzle, and the threaded block is fixed to the outer tube of the air nozzle by rotating the threaded block. When the device is ready to be inflated, the movable rod and the limiting rod of the intake device are driven by an external inflating device to rotate along the L-shaped limiting chute.

[0032] Embodiment 1

[0033] In some embodiments, please refer to the attached drawings of the specification Figures 1-5 , a special-shaped rubber sealing ring that can effectively prevent detachment, including a rubber sealing ring 1;

[0034] An air nozzle assembly 2 for air intake is installed on the rubber sealing ring 1;

[0035] The air nozzle assembly 2 includes an air nozzle device 21 and an air intake device 22. The rubber sealing ring 1 is connected to the air nozzle device 21, and the air nozzle device 21 is connected to the air intake device 22;

[0036] The air nozzle device 21 includes an air nozzle outer tube 211, an air nozzle inner tube 212, and a threaded block 213. The front end of the rubber sealing ring 1 is fixedly connected to the air nozzle outer tube 211. The inner wall of the front end of the air nozzle outer tube 211 is threadedly connected to the threaded block 213. The threaded block 213 is connected to the air intake device 22. The rear end of the threaded block 213 is fixedly connected to the air nozzle inner tube 212, and the air nozzle inner tube 212 is connected to the air intake device 22;

[0037] The air intake device 22 includes a movable rod 221, a sealing block 222, a baffle 223, a spring 224, a limiting rod 225, an L-shaped limiting chute 226, and a slot hole 227. A slot hole 227 is opened at the front end of the threaded block 213. A pair of L-shaped limiting chutes 226 are opened on the inner wall of the air nozzle inner tube 212. A baffle 223 is fixedly connected to the inner wall of the rear end of the air nozzle inner tube 212. One end of the spring 224 is fixedly connected to the upper end of the baffle 223. The other end of the spring 224 is in contact connection with the limiting rod 225. The limiting rod 225 is slidably connected in the L-shaped limiting chute 226. The inner wall of the limiting rod 225 is fixedly connected to the movable rod 221. The front end of the movable rod 221 is slidably connected to the inner wall of the slot hole 227. The rear end of the movable rod 221 is fixedly connected to the sealing block 222. The front end of the sealing block 222 is in fitting connection with the air nozzle inner tube 212;

[0038] Preferably, the sealing block 222 is made of rubber material;

[0039] The sealing block 222 made of the rubber material is soft in texture and can better fit with the inner tube 212 of the air nozzle to complete the sealing;

[0040] In the embodiment of the present invention, when the device is ready for installation, the inner tube 212 and the threaded block 213 of the air nozzle device 21 of the air nozzle assembly 2 are inserted into the outer tube 211 of the air nozzle, and the threaded block 213 is fixed to the outer tube 211 of the air nozzle by rotating the threaded block 213. When the device is ready for inflation, the movable rod 221 and the limiting rod 225 of the air inlet device 22 are driven by an external inflation device to rotate along the L-shaped limiting chute 226. When rotating to the inflection point of the L-shaped limiting chute 226, the movable rod 221 and the limiting rod 225 are driven by the external inflation device to move backward along the L-shaped limiting chute 226. The limiting rod 225 that moves backward compresses the spring 224 to contract. At the same time, the movable rod 221 drives the sealing block 222 to move backward along the slot hole 227 to separate from the inner tube 212 of the air nozzle. At this time, the device can be inflated. The function of the baffle 223 is to support the spring 224. When the inflation is over, the spring 224 resets to drive the movable rod 221 and the limiting rod 225 to move forward. The movable rod 221 that moves forward drives the sealing block 222 to closely fit with the inner tube 212 of the air nozzle to avoid air leakage. The movable rod 221 is driven to rotate by an external inflation device, and the limiting rod 225 is driven to rotate along the L-shaped limiting chute 226 by the rotation of the movable rod 221 to clamp the limiting rod 225. After rotating the movable rod 221 to a specific position, the device is inflated. After inflation, the limiting rod 225 is clamped to avoid air leakage from the device due to the loosening of the movable rod 221 or manual pressing, so that the rubber sealing ring 1 cannot closely fit with the device and loses the sealing effect.

[0041] A anti-disengagement device 4 for locking is installed on the rubber sealing ring 1, and the anti-disengagement device 4 is connected to the pipeline assembly 3;

[0042] The anti-disengagement device 4 includes a T-shaped anti-disengagement block 41. A plurality of T-shaped anti-disengagement blocks 41 are fixedly connected to the inner wall of the rubber sealing ring 1 at equal intervals, and the T-shaped anti-disengagement blocks 41 are connected to the pipeline assembly 3;

[0043] In the embodiment of the present invention, when the device starts to be installed, the T-shaped anti-disengagement block 41 of the anti-disengagement device 4 is docked with the pipeline assembly 3. After the docking is completed, gas is introduced into the T-shaped anti-disengagement block 41. After the gas is injected into the T-shaped anti-disengagement block 41, it gradually expands and closely fits with the pipeline assembly 3 to complete the fixation. After the protruding part of the T-shaped anti-disengagement block 41 closely fits with the pipeline assembly 3, it is fixed to avoid falling off from the pipeline assembly 3 due to friction after the device operates, resulting in sealing failure.

[0044] A pipeline assembly 3 is installed on the rubber sealing ring 1, and the pipeline assembly 3 is connected to the anti-disengagement device 4;

[0045] The pipeline component 3 includes a pipeline 31 and a locking groove 32. The inner wall of the rubber sealing ring 1 is fitted and connected to the outer wall of the pipeline 31. A plurality of locking grooves 32 are equidistantly arranged on the outer wall of the pipeline 31, and the inner walls of the locking grooves 32 are respectively and correspondingly clamped with the T-shaped anti-disengagement blocks 41.

[0046] In the embodiment of the present invention, when the device starts to be installed, the locking grooves 32 formed on the pipeline 31 of the pipeline component 3 are docked with the T-shaped anti-disengagement blocks 41 one by one. When the T-shaped anti-disengagement blocks 41 are filled with gas and tightly fit with the locking grooves 32 with a large front end and a small rear end, the T-shaped anti-disengagement blocks 41 are clamped. At the same time, the outer wall of the pipeline 31 is fitted with the rubber sealing ring 1 filled with gas to complete the sealing. By the cooperative installation of the specific pipeline 31 and the T-shaped anti-disengagement blocks 41, the rubber sealing ring 1 can be restricted to a specific position on the pipeline 31 so that it does not shift, and better sealing can be achieved.
