Description

Technical Field

[0001] This utility model is a wheel explosion-proof device, belonging to the field of tire explosion-proof. Background Technology

[0002] Currently, tire inflators for concrete mixer trucks are typically used. These inflators are pre-set with a pressure rating based on the tire's capacity, and each inflation is performed according to this rating. However, concrete mixer trucks are primarily used in construction projects, where the working environment is generally harsh, with uneven roads. This makes the tires prone to wear and tear or other damage, reducing their pressure resistance during inflation. If the pre-set pressure is consistently maintained, the tire may explode.

[0003] Existing solutions to tire blowout problems primarily focus on preventing tire blowouts during driving. Therefore, tire blowout prevention often addresses the properties and structure of the tire itself. However, tire blowouts can cause problems not only during driving but also during inflation. The main concern with blowouts during inflation is the potential for injury from the resulting air pressure and debris. While modifying the tire's properties to reduce the likelihood of blowouts during inflation is feasible, it is relatively costly. Therefore, new blowout prevention devices need to be designed to address the problems caused by tire blowouts during inflation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wheel explosion-proof device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An explosion-proof wheel device includes an explosion-proof box frame, a plurality of mounting slots on the side of the explosion-proof box frame, a box plate in the mounting slot, a connecting mechanism that cooperates with the box plate in the inner wall of the explosion-proof box frame, and a wheel groove at the center of the bottom of the explosion-proof box frame.

[0007] Furthermore, the box panel includes two protective panels, and a handle is provided on the middle of the side of each protective panel.

[0008] Furthermore, the connecting mechanism includes a U-shaped groove formed on the top of the explosion-proof box frame, and a movable groove extending through the inner wall of the explosion-proof box frame at each of the four corners of the U-shaped groove. A turntable and a rotating column are rotatably connected inside the movable groove. The rotating column and the turntable are connected and fixed by a connecting shaft. A row of track plates is provided on both sides of the outer surface of the rotating column. An inlet and outlet extending through the mounting groove are formed on the inner wall of the movable groove.

[0009] Furthermore, a fixed angle plate is fixed on the inner wall of the movable groove and on the side of the inlet and outlet. A sliding block is linearly slidably connected to the fixed angle plate. A protrusion is fixed on the top of the sliding block and penetrates into the track plate. An inclined plate is fixed on the side of the sliding block and penetrates into the mounting groove through the inlet and outlet. A slot that cooperates with the inclined plate is opened on the side of the protective plate.

[0010] Furthermore, two gripping blocks are symmetrically slidably connected to the top of the turntable, and a limiting groove that cooperates with the gripping blocks is provided on the inner wall of the top opening of the movable groove.

[0011] Furthermore, two positioning grooves are symmetrically opened on the top outer surface of the turntable, a sealing plate is placed in the groove, and a set of positioning rods that cooperate with the positioning grooves are respectively provided at the four corners of the sealing plate.

[0012] Furthermore, the fixed angle plate is provided with a sliding groove that cooperates with the sliding block, and a damping spring connected to the sliding block is provided on the inner wall of the sliding groove.

[0013] The beneficial effects of this utility model are:

[0014] Through the design of the connecting mechanism, the turntable is held and rotated. The turntable drives the rotating column to rotate through the connecting shaft. The rotation of the rotating column drives several track plates on the side to rotate. The rotating track plates squeeze the protrusions, which in turn drives the sliding block to move linearly on the fixed corner plate. As the sliding block moves, it also drives the inclined plate to move. The inclined plate disengages from the slot on the side of the protective plate, thus realizing the disengagement of the protective plate from the installation slot on one side.

[0015] Through the design of the gripping block and the limiting groove, after the turntable is rotated and adjusted, the gripping block on the top of the turntable is pushed to move, so that the end of the gripping block is engaged in the limiting groove, thereby limiting the turntable.

[0016] The box design, consisting of two protective panels, not only seals the mounting slots on the side of the explosion-proof box frame but also facilitates the disassembly of the box panels, allowing tires to easily enter and exit the explosion-proof box.

[0017] The design of the positioning groove and positioning rod allows the turntable to be fixed in place by inserting the positioning rod at the bottom of the sealing plate into the positioning groove after the sealing plate is placed inside the groove, thus improving the stability of the connection mechanism.

[0018] The design of the damping spring provides power for the sliding block to return to its original position. Attached Figure Description

[0026] 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution for a wheel explosion-proof device, including an explosion-proof box frame 1. The side of the explosion-proof box frame 1 is provided with a plurality of mounting grooves 3. A box plate is provided in the mounting groove 3. A connecting mechanism that cooperates with the box plate is provided in the inner wall of the explosion-proof box frame 1. A wheel groove 2 is opened at the center of the bottom of the explosion-proof box frame 1.

[0028] See Figure 1 , Figure 4 The box panel includes two protective plates 17, and a handle 18 is provided in the middle of the side of the protective plate 17. Through the design of the box panel, the box panel composed of two protective plates 17 can not only block the mounting groove 3 on the side of the explosion-proof box frame 1, but also facilitate the disassembly of the box panel, thereby facilitating the entry and exit of tires from the explosion-proof box.

[0029] See Figures 2-5 The connecting mechanism includes a U-shaped groove 4 formed on the top of the explosion-proof box frame 1. At each of the four corners of the U-shaped groove 4, a movable groove 5 is formed, penetrating into the inner wall of the explosion-proof box frame 1. A turntable 6 and a rotating column 7 are rotatably connected inside the movable groove 5. The rotating column 7 and the turntable 6 are connected and fixed by a connecting shaft 8. A row of track plates 9 is provided on both sides of the outer surface of the rotating column 7. An inlet and outlet are formed on the inner wall of the movable groove 5, penetrating into the mounting groove 3. A fixing angle plate 10 is fixed on the inner wall of the movable groove 5, located on the side of the inlet and outlet. A sliding block 11 is linearly slidably connected to the fixing angle plate 10. A protrusion 12 is fixed to the top of the sliding block 11. 2. The sliding block 11 is fixed with a sloping plate 13 on its side. The sloping plate 13 passes through the inlet and outlet into the mounting groove 3. The side of the protective plate 17 is provided with a slot that cooperates with the sloping plate 13. Through the design of the connecting mechanism, the turntable 6 is rotated by holding it. The turntable 6 drives the rotating column 7 to rotate through the connecting shaft 8. The rotation of the rotating column 7 drives the several track plates 9 on the side to rotate. The rotation of the track plates 9 squeezes the protrusion 12, thereby driving the sliding block 11 to move linearly on the fixed corner plate 10. When the sliding block 11 moves, it will drive the sloping plate 13 to move. The sloping plate 13 disengages from the slot on the side of the protective plate 17, thereby realizing the disengagement of the protective plate 17 in the mounting groove 3 on one side.

[0030] See Figure 3 , Figure 5 Two gripping blocks 14 are symmetrically slidably connected to the top of the turntable 6. A limiting groove 19 that cooperates with the gripping blocks 14 is provided on the inner wall of the top opening of the movable groove 5. Through the design of the gripping blocks 14 and the limiting groove 19, after the turntable 6 is rotated and adjusted, the gripping blocks 14 on the top of the turntable 6 are pushed to move, so that the end of the gripping block 14 is engaged in the limiting groove 19, thereby limiting the turntable 6.

[0031] See Figure 5 The top outer surface of the turntable 6 has two symmetrically arranged positioning grooves 15. A sealing plate 16 is placed in the loop groove 4. At each of the four corners of the sealing plate 16, there is a set of positioning rods (not shown in the figure) that cooperate with the positioning grooves 15. Through the design of the positioning grooves 15 and positioning rods, after the sealing plate 16 is placed inside the loop groove, the positioning rods at the bottom of the sealing plate 16 can be inserted into the positioning grooves 15 to limit the turntable 6, thereby improving the stability of the connection mechanism. The fixed corner plate 10 has a sliding groove (not shown in the figure) that cooperates with the sliding block 11. A damping spring (not shown in the figure) connected to the sliding block 11 is provided on the inner wall of the sliding groove. Through the design of the damping spring, the power can be provided for the reset movement of the sliding block 11.

[0032] In use, remove one side of the enclosure door, then place the removed tire inside the explosion-proof enclosure. Connect the tire to the tire via an air valve located on one side of the enclosure door. Next, seal the enclosure door in the mounting groove 3 on the side of the explosion-proof enclosure frame 1 to complete the enclosure. Inflate the tire. After inflation, remove the sealing plate 16 from the top of the explosion-proof enclosure to expose the U-shaped groove 4. Then, grasp the grip block 14 to rotate the turntable 6. The turntable 6, through the connecting shaft 8, drives the rotating column 7 to rotate, which in turn rotates several side track plates 9. The track plate 9 rotates and presses against the protrusion 12, thereby causing the sliding block 11 to move linearly on the fixed angle plate 10. As the sliding block 11 moves, it also causes the inclined plate 13 to move. The inclined plate 13 disengages from the slot on the side of the protective plate 17, thereby disengaging the protective plate 17 from the mounting slot 3 on one side. It then pushes the gripping block 14 on the top of the turntable 6 to move, so that the end of the gripping block 14 engages with the limiting slot 19, thereby limiting the turntable 6. Then, by gripping the handle 18, the protective plate 17 is deflected to an inclined state, and the protective plate 17 is removed through the connecting line of the mounting slot 3, making it easy to remove the wheel.
