[0002] When repairing and installing tires on engineering vehicles, it is necessary to push out the valve stem inside the tire to separate the inner tube from the outer tire. However, using conventional tools to push out the valve stem is difficult and cumbersome, wasting a lot of time and potentially damaging the inner tube during the process. Similarly, installing the valve stem without specialized equipment also takes considerable time. Furthermore, workers need to carry a large number of tools when pushing out valve stems for various types of engineering tires.

[0003] To address the aforementioned issues, this invention provides a multi-functional engineering tire valve pusher, designed to improve the efficiency of valve operation during the repair and installation of engineering vehicle tires, reduce the risk of damage to the inner tube, and decrease the number of tools and inconvenience for workers. This multi-functional engineering tire valve pusher is equipped with a specially designed push-out component adapted to different types of engineering tire valves. Through a clever mechanical structure, it can easily and quickly push out the valve, applying precise force regardless of tire specifications or models, effectively preventing scratches, tears, or other damage to the inner tube. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multifunctional engineering tire valve removal device, which aims to improve the problem that the existing valve removal devices cannot be applied to multiple types of tires.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional engineering tire deflector, comprising a push rod, a push nozzle recess fixedly connected to the rear side of the push rod, two push nozzle offset blocks fixedly connected to the rear side of the push nozzle recess, a push nozzle groove formed on the rear side of the push nozzle recess, a fixing component slidably connected to the outside of the push rod, a push nozzle column fixedly connected to the front side of the push rod, a push nozzle cone fixedly connected to the front side of the push nozzle column, a fixing triangular plate fixedly connected to the bottom of the push nozzle column, a fixing recess fixedly connected to the top of the fixing triangular plate, and a fixing groove formed in the middle of the fixing recess;

[0006] As a further description of the above technical solution: the fixing component includes a sliding housing, the inside of which is slidably connected to the outside of the push rod, a limiting slider is provided on the inner side of the sliding housing, and connecting rods are fixedly connected to both the left and right sides of the sliding housing;

[0007] As a further description of the above technical solution: the two connecting rods are externally fixedly connected to a tire expander connecting block, and the front top of the tire expander connecting block is fixedly connected to a tire expander barb;

[0008] As a further description of the above technical solution: a gear plate is provided at the top of the push rod, and a moving gear is meshed with the outside of the gear plate;

[0009] As a further description of the above technical solution: a protective shell is fixedly connected to the top of the sliding shell, and two return springs are fixedly connected to the top of the rear side of the sliding shell;

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, a double-ended valve pusher is provided at both ends to accommodate different tire models. Construction vehicles come in a wide variety, such as large cranes and small forklifts, with vastly different tire sizes and valve specifications. Previously, workers needed to carry multiple tools and frequently change valves during installation and removal, which was time-consuming and prone to errors. Now, with the double-ended valve pusher, workers only need to carry one tool to quickly adapt to different tires. This enhances operational continuity, significantly improves efficiency, and also avoids improper compression of the valve, effectively reducing the risk of damage.

When dealing with engineering tires of different widths, the gear and rack mechanism can be flexibly adjusted to adapt to the tire size and ensure a stable clamping. Combined with the locking structure, the tire can be firmly fixed during disassembly and installation, preventing shaking and displacement. Attached Figure Description

[0023] 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.

[0024] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a multifunctional engineering tire valve release device, with an overall length of 62cm. It includes a push rod 1, the main structure of the valve release device, which supports and connects other components. A valve release block 6 is fixedly connected to the rear side of the push rod 1, generating thrust by pushing the valve stem. Two valve release offset blocks 7 are fixedly connected to the rear side of the valve release block 6. The shape of the valve release offset blocks 7 is slightly downward offset, in the opposite direction to the tire expander hook 5, and can be used as a pry bar to transmit thrust. A valve release groove 8 is provided on the rear side of the valve release block 6 to fix the position of the valve stem. The outer side of the push rod 1... The sliding connection has a fixed component. The front side of the push rod 1 is fixedly connected to the push nozzle column 9 to transmit thrust and fix the fixed triangular plate 11. The front side of the push nozzle column 9 is fixedly connected to the push nozzle cone 10, which is tapered at the front end to push the valve nozzle to move. The bottom of the push nozzle column 9 is fixedly connected to the fixed triangular plate 11, which connects the push nozzle column 9 and the fixed recess 12. The top of the fixed triangular plate 11 is fixedly connected to the fixed recess 12. The length of the fixed recess 12 is longer than the length of the fixed triangular plate 11 so that it can be locked in the groove of the rim inside the tire. The middle part of the fixed recess 12 is provided with a fixed groove 13 to enhance the fixing effect.

[0025] The fixing component includes a sliding housing 2, which drives the tire expander hook 5 to move. The inside of the sliding housing 2 is slidably connected to the outside of the push rod 1. A limiting slider 25 is provided on the inside of the sliding housing 2 to fix the sliding housing 2 and prevent it from falling off the track of the push rod 1. At the same time, it allows the sliding housing 2 to slide within the range of the gear plate 14. Connecting rods 3 are fixedly connected to both the left and right sides of the sliding housing 2. The tire expander connecting block 4 is fixedly connected to the outside of the two connecting rods 3 to connect the sliding housing 2 and the tire expander hook 5 and transmit the motion effect. The front top of the tire expander connecting block 4 is fixedly connected to the tire expander hook 5, which is hook-shaped and can hook onto the steel rim of the tire to play a fixing role.

[0026] Reference Figure 1 , Figure 3 The top of the sliding housing 2 is fixedly connected to a protective housing 15, which protects the internal locking and unlocking components. The top of the rear side of the sliding housing 2 is fixedly connected to two return springs 16, which lock and reset the moving fixed block 17 after unlocking and locking. The inside of the protective housing 15 is fixedly connected to a fixed rotating shaft 18, which serves as the rotation center of the moving fixed block 17. The outside of the fixed rotating shaft 18 is rotatably connected to the moving fixed block 17, which serves to fix the moving gear 20. The other end of the two return springs 16 is fixedly connected to the rear outer wall of the fixed rotating shaft 18. The inside of the protective housing 15 is fixedly connected to a moving rotating shaft 19, which serves as the rotation center of the moving gear 20. The outside of the moving rotating shaft 19 is rotatably connected to the moving gear 20. The moving gear 20 meshes with the gear plate 14, which drives the protective housing 15 and the sliding housing 2 to move back and forth.

[0027] Reference Figure 1 , Figure 5 The top of the push rod 1 is provided with a gear plate 14. The moving gear 20 meshes with the gear plate 14, driving the protective shell 15 and the sliding shell 2 to move back and forth. The gear plate 14 is externally connected to the moving gear 20. The moving shaft 19 is externally rotatably connected to the moving plate 21, driving the movable shaft 22 and the release block 23 to rotate. The movable shaft 22 is fixedly connected to the middle of the moving plate 21, serving as the rotation center of the release block 23. The release block 23 is rotatably connected to the outside of the movable shaft 22, and cooperates with the moving fixed block 17 to unlock the moving gear 20. The top of the moving plate 21 is fixedly connected to a handle 24, which facilitates the operation of locking and unlocking by the staff.

[0028] Working Principle: For certain models of engineering vehicle tires, the worker first holds the device and presses the push rod 1 downwards. At this time, the fixing recess 12 at one end of the pusher will, as the push rod 1 is pressed down, engage the valve stem through the matching fixing groove 13, ensuring the valve stem is firmly fixed. Next, the worker slowly pulls the push rod 1 back, causing the fixing recess 12 to smoothly enter the appropriate position above the tire rim and firmly lock onto the rim, providing stable support for subsequent operations. After fixing, the worker carefully aligns the pusher cone 10 with the hole at the base of the valve stem, firmly grips the push rod 1 with both hands, and pushes forward. Under the pushing force, the pusher column 9 evenly transmits the force to the pusher cone 10. As the pushing force gradually increases, the pusher cone 10 continuously squeezes the base of the valve stem, eventually slowly pushing the valve stem out, allowing it to smoothly detach from the pre-reserved notch at the tire edge, thus effectively separating the tire pad from the inner tube.

[0029] The operating method differs for other types of engineering vehicle tires. First, the operator tilts the multi-functional engineering tire pusher at a certain angle, aligning the pusher groove 8 on the pusher block 6 with the root of the valve stem. Simultaneously, the pusher offset block 7 secures the root of the valve stem in the center of the pusher groove 8, preventing valve stem misalignment. Next, the operator pushes the device into the tire. During this process, the expander hook 5 on the expander connecting block 4 engages with the inner rim of the tire, using this rim as a solid fixing point. Then, the operator rotates the handle 24, causing the expander hook 5 to engage with the inner rim of the tire. Finally, the operator pushes the push rod 1, transferring the force to the valve stem, causing it to gradually detach from the notch, successfully separating the tire pad from the inner tube, laying the foundation for subsequent tire repair or installation.

[0030] When the position of the tire expander connecting block 4 needs to be locked, the moving fixing block 17, through the action of two return springs 16, will have its protruding structure lock the rear end of the moving gear 20, while the bottom protrusion of the release block 23 will lock the front end of the moving gear 20, preventing the moving gear 20 from moving on the gear plate 14, thus achieving a locking effect. To unlock, the operator turns the handle 24, causing the moving rotating plate 21 to rotate around the moving shaft 19. When rotating the front side, the release block 23 inside the moving rotating plate 21 will cause the front protrusion to press against the middle of the moving fixing block 17, thereby disengaging the moving fixing block 17 from the moving gear 20. In this way, the sliding housing 2 can slide freely outside the push rod 1, completing the unlocking operation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
