Description

Technical Field

[0001] This utility model relates to the field of tire deflator technology, specifically a non-embedded double-row tire deflator. Background Technology

[0002] The non-embedded double-row tire deflation device is a safety device used to control vehicle passage. It is mainly used to prevent vehicles from violently running through checkpoints. The non-embedded double-row tire deflation device has two functions: deceleration and tire puncture. It can effectively control vehicle deceleration, prevent vehicles from recklessly running through checkpoints, and ensure the personal and property safety of vehicle inspection personnel and unit security personnel. When a vehicle tire runs over the tire deflation device, the sharp puncture will penetrate the tire in a very short time and release the air in the tire through the vent hole, causing the vehicle to stop moving.

[0003] Existing tire deflation devices require deployment to block vehicles in special circumstances. However, deployment takes a lot of time, and while small tire deflation devices can puncture tires, they cannot completely prevent vehicles from passing. To completely block vehicles, large tire deflation devices need to be moved and deployed, which is not only more laborious but also wastes more time. This makes them unsuitable for emergency situations. Furthermore, they are inconvenient to move and disassemble quickly during use, and cannot be quickly retracted when not in use. Therefore, this application proposes an alternative technical solution to address this problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a non-burial double-row tire deflation device, which has the advantages of convenient and quick assembly and disassembly of the tire deflation device, and the ability to quickly retract the tire deflation device to allow vehicles to pass normally. It solves the problems of not being able to completely prevent vehicles from entering, requiring the transportation and placement of large tire deflation devices to completely block vehicles, which is not only more laborious and time-consuming, but also unsuitable for emergency situations. Furthermore, it is inconvenient to quickly move and assemble the tire deflation device during use, and it is not possible to quickly retract the tire deflation device when it is not needed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-burial double-row tire debriding device, including a caster wheel, wherein an adjustment and retraction mechanism is provided on the top of the caster wheel;

[0006] The adjustment and recovery mechanism includes a fixed base fixedly installed on the top of the universal wheel, a partition fixedly installed inside the fixed base, a rotary motor fixedly installed on the inner walls of both the left and right sides of the fixed base, a reciprocating screw fixedly installed on the output shaft of the rotary motor and rotatably connected to the partition, and a threaded block threadedly connected to the outer side of the reciprocating screw.

[0007] A hinge seat is fixedly installed on the top of the threaded block, and a support rod is hinged inside the hinge seat. Mounting plates are hinged on both the left and right sides of the partition. A tire-breaking sharp tooth that is hinged to the support rod is fixedly installed on one side of the mounting plate. An auxiliary component is provided on the front of the universal wheel.

[0008] The auxiliary component includes a movable platform with omnidirectional wheels hinged to the front. The bottom of the movable platform is fixedly equipped with auxiliary wheels, the top of the movable platform is fixedly equipped with a fence, and the bottom of the movable platform is fixedly equipped with a threaded shaft. The outer side of the threaded shaft is threaded with lifting legs.

[0009] Furthermore, bearing grooves are provided on both the left and right sides of the partition, and the reciprocating lead screw is rotatably connected to the partition through the bearing grooves.

[0010] Furthermore, the threaded block has a threaded groove inside, and the threaded block is threadedly connected to the reciprocating lead screw through the threaded groove.

[0011] Furthermore, the number of tire-breaking teeth is several, and the multiple tire-breaking teeth are evenly arranged on one side of the mounting plate.

[0012] Furthermore, the top of the fixed base is provided with several limiting grooves corresponding to the tire-breaking teeth, and the tire-breaking teeth are movably connected to the fixed base through the limiting grooves.

[0013] Furthermore, the lifting leg has a threaded groove inside, and the lifting leg is threadedly connected to the threaded shaft through the threaded groove.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This non-embedded double-row tire deflation device, through its adjustable recovery mechanism, uses a rotary motor and a reciprocating screw to move a threaded block and a hinge seat, thereby lifting a support rod. This lifting of the support rod, in turn, lifts the tire-deflation teeth and mounting plate, causing them to rotate on the left and right sides of the partition, thus further lifting the tire-deflation teeth. Alternatively, the rotary motor can drive the reciprocating screw to rotate in the opposite direction, causing the threaded block to move in the opposite direction, which in turn moves the support rod downwards, causing the tire-deflation teeth to retract and allowing subsequent vehicles to pass normally. This increases the device's flexibility and practicality. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 In this embodiment, a tire-breaking device that does not require burial includes a caster wheel 1, and an adjustment and retraction mechanism is provided on the top of the caster wheel 1.

[0022] In this embodiment, the adjustment and recycling mechanism includes a fixed base 2 fixedly installed on the top of the universal wheel 1. A partition 3 is fixedly installed inside the fixed base 2. A rotary motor 4 is fixedly installed on the inner walls of both the left and right sides of the fixed base 2. A reciprocating screw 5 rotatably connected to the partition 3 is fixedly installed on the output shaft of the rotary motor 4. Bearing grooves are provided on both the left and right sides of the partition 3. The reciprocating screw 5 is rotatably connected to the partition 3 through the bearing grooves, which helps the reciprocating screw 5 to rotate.

[0023] Among them, the reciprocating screw 5 is threadedly connected to the outer side of the threaded block 6, and the threaded block 6 has a threaded groove inside. The threaded block 6 is threadedly connected to the reciprocating screw 5 through the threaded groove, which helps the threaded block 6 to move on the outer side of the reciprocating screw 5. The top of the threaded block 6 is fixedly installed with a hinge seat 7, and a support rod 8 is hinged inside the hinge seat 7. Mounting plates 9 are hinged to both sides of the partition 3. A tire-breaking sharp tooth 10 that is hinged to the support rod 8 is fixedly installed on one side of the mounting plate 9.

[0024] In this embodiment, the top of the fixed base 2 is provided with several limiting grooves corresponding to the tire-breaking teeth 10. The tire-breaking teeth 10 are movably connected to the fixed base 2 through the limiting grooves, so that multiple tire-breaking teeth 10 can more effectively intercept vehicles. The number of tire-breaking teeth 10 is several, and multiple tire-breaking teeth 10 are evenly arranged on one side of the mounting plate 9.

[0025] In embodiment 2, an auxiliary component is provided on the front of the caster wheel 1. The auxiliary component includes a movable platform 11 hinged to the front of the caster wheel 1. An auxiliary wheel 12 is fixedly installed at the bottom of the movable platform 11. A railing 13 is fixedly installed at the top of the movable platform 11. A threaded shaft 14 is fixedly installed at the bottom of the movable platform 11. A lifting leg 15 is threadedly connected to the outer side of the threaded shaft 14. A threaded groove is provided inside the lifting leg 15. The lifting leg 15 is threadedly connected to the threaded shaft 14 through the threaded groove, which helps the lifting leg 15 to move up and down outside the threaded shaft 14.

[0026] It should be noted that this non-burial double-row tire puncture device, through its adjustable recovery mechanism, uses a rotary motor 4 and a reciprocating screw 5 to move the threaded block 6 and the hinge seat 7, thereby lifting the support rod 8. The lifting of the support rod 8 lifts the tire puncture teeth 10 and the mounting plate 9, causing the tire puncture teeth 10 and the mounting plate 9 to rotate on the left and right sides of the partition 3, thus lifting the tire puncture teeth 10. Alternatively, the rotary motor 4 can drive the reciprocating screw 5 to rotate in the opposite direction, which can move the threaded block 6 in the opposite direction, causing the support rod 8 to move the tire puncture teeth 10 downward, thereby retracting the tire puncture teeth 10 and facilitating the normal passage of subsequent vehicles, increasing the flexibility and practicality of the device.

[0027] The working principle of the above embodiments is as follows:

[0028] This non-burial double-row tire deflation device, when used to intercept vehicles on the road, can first be moved to the road to be intercepted via the casters 1 and the casters 1 fixed. Then, the lifting leg 15 can be rotated, causing it to move downwards and touch the ground, thus limiting and fixing the entire device. Then, the rotary motor 4 can be started, driving the reciprocating screw 5 to rotate. The threaded block 6 on the outer side of the reciprocating screw 5 begins to move under the limitation of the support rod 8. When the two threaded blocks 6 move towards each other, they can drive the threaded block 6 and the hinge seat 7 to move, thereby lifting the support rod 8. The lifting of the support rod 8 then engages the tire deflation teeth 10. The mounting plate 9 is lifted, causing the tire-puncturing teeth 10 and the mounting plate 9 to rotate on the left and right sides of the partition 3, thereby lifting the tire-puncturing teeth 10 and pushing them out. When a vehicle passes the moving platform 11 to the top of the fixed base 2, the tires of the moving vehicle can be punctured and intercepted. When it is not necessary to intercept the vehicle, the rotary motor 4 can be started to drive the reciprocating screw 5 to rotate in the opposite direction. The reciprocating screw 5 rotates in the opposite direction, which drives the threaded block 6 to move in the opposite direction, causing the support rod 8 to move the tire-puncturing teeth 10 downward, thereby retracting the tire-puncturing teeth 10, so that subsequent vehicles can pass normally, which greatly improves the flexibility and practicality of the device.
