Description

Technical Field

[0001] This utility model relates to the technical field of tire testing equipment, and in particular to a tire pressure gauge with a rotary valve connector. Background Technology

[0002] As a key component of a vehicle in contact with the ground, the proper air pressure inside tires directly affects driving safety, fuel economy, and the tire's lifespan. Therefore, regularly checking tire pressure with a tire pressure gauge is an indispensable part of routine vehicle maintenance.

[0003] Currently, most commercially available tire pressure gauges typically consist of a pressure gauge dial, connecting tubing, and a valve connector that mates with the tire valve. When using the gauge, the operator holds it and presses the valve connector vertically or at a fixed angle onto the tire valve, opening the valve core and allowing air from the tire to enter the gauge for reading.

[0004] However, in actual use, due to the diversity of wheel hub structures, brake system layouts, and the installation position and angle of the valve stem itself in different vehicles, situations often arise where the valve stem is in a narrow space or at a special angle. For valve stems in such non-ideal positions, traditional one-piece or fixed-angle valve stem connectors are often difficult to align and press smoothly. The operator needs to laboriously adjust the angle of the entire tire pressure gauge, which is not only very inconvenient to operate, but also prone to tire air leakage due to poor sealing during repeated alignment attempts, affecting the accuracy of the measurement results.

[0005] Therefore, this utility model proposes a tire pressure gauge with a rotary valve connector to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a tire pressure gauge with a rotary valve connector, aiming to improve the technical problem that the valve connector angle of the existing tire pressure gauge is fixed, making it difficult to connect with the tire valve in a special position.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a tire pressure gauge with a rotary valve connector, comprising a handle, a pressure gauge, an air tube, and a connecting assembly; and a rotating assembly disposed between the air tube and the connecting assembly, the rotating assembly comprising a hollow fixed tube, a rotating shaft, a rotating block, a rotating plate, a connecting tube, and a flexible hose, the fixed tube being fixedly connected to the end of the air tube, the rotating shaft being rotatably inserted inside the fixed tube, the rotating block being fixedly connected to the outer periphery of the rotating shaft, the rotating plate being fixedly connected to the end of the rotating shaft away from the air tube, the connecting tube being fixedly connected to the rotating plate, and connected to the connecting assembly through the hose to form a connected air passage.

[0008] Preferably, the front end of the connecting component is detachably connected to an air nozzle via a thread.

[0009] Preferably, the valve is any one of the first valve, the second valve, and the third valve to adapt to tire valves of different specifications.

[0010] Preferably, a sealing ring is fitted around the base of the air nozzle to enhance airtightness during connection.

[0011] Preferably, the connecting component includes a fixing frame, the fixing frame housing a spring and a pin.

[0012] Preferably, the spring is sleeved on the rod of the ejector pin, with one end of the spring abutting against the inner wall of the fixing frame and the other end abutting against the flange of the ejector pin.

[0013] Preferably, the outer wall of the fixed frame is slidably fitted with a sliding frame, which is used to push the ejector pin to move axially.

[0014] Preferably, the tire pressure gauge with a rotary valve connector further includes a connecting rope and a connecting ring. The connecting rope is connected to the handle, and the connecting ring is located at the end of the connecting rope for hanging and storage.

[0015] Preferably, a fixing ring is slidably disposed on the connecting rope, and the fixing ring is used to position the connecting ring.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that the tire pressure gauge connector angle is fixed and it is difficult to align with the tire valve in a tricky position, resulting in inconvenient operation, by setting a rotating assembly consisting of a fixed tube, a rotating block, a rotating shaft, a rotating plate and a flexible hose. It achieves the effect of flexibly adjusting the connection angle and conveniently and quickly measuring tire pressure.

[0018] 2. This utility model solves the problem that traditional tire pressure gauges cannot be adapted to all types of tire valves due to their single interface, thus limiting their applicability. By setting various specifications of detachable threaded valves on the connecting components, this invention enhances the versatility of the device, making it applicable to different vehicles and tires.

[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] Reference Figures 1-5This utility model provides an embodiment of a tire pressure gauge with a rotary valve connector, including a handle 2. A pressure gauge 1 is fixedly connected to one end of the handle 2, and the pressure gauge 1 is connected to one end of an air tube 3. The tire pressure gauge also includes a connecting assembly 8 for docking with a tire valve and a rotating assembly 7 disposed between the other end of the air tube 3 and the connecting assembly 8. The input end of the rotating assembly 7 is fixedly connected to and communicates with the other end of the air tube 3, and the output end of the rotating assembly 7 is connected to the connecting assembly 8. The rotating assembly 7 includes a hollow fixed tube 701, which serves as the input end of the rotating assembly 7 and is fixedly connected to the end of the air tube 3. The rotating assembly 7 also includes a rotating shaft 703, which is rotatable. The rotating shaft 703 is movably inserted into the fixed tube 701, thus realizing the basic function of rotation. A rotating block 702 is fixedly connected to the outer periphery of the rotating shaft 703. The rotating block 702 is used to drive the rotating shaft 703 to rotate. A rotating plate 704 is fixedly connected to the end of the rotating shaft 703 away from the air tube 3. The rotating plate 704 will rotate synchronously with the rotation of the rotating shaft 703. A hollow connecting tube 705 is fixedly connected to the rotating plate 704. The connecting tube 705 is connected to the connecting assembly 8 through a flexible hose 706 to realize the air passage connection. The connecting tube 705 and the hose 706 together constitute the output end of the rotating assembly 7. The setting of the hose 706 makes the position adjustment of the connecting assembly 8 more flexible.

[0028] To achieve precise alignment with the tire valve and air passage opening, the tire pressure gauge connection assembly 8 with a rotary valve connector integrates a specific opening and sealing structure. The connection assembly 8 includes a fixing frame 805 as its main structure. The fixing frame 805 houses a spring 806 and a ejector pin 807. The spring 806 is sleeved on the rod of the ejector pin 807. One end of the spring 806 abuts against the inner wall of the fixing frame 805, and the other end abuts against the flange of the ejector pin 807. The elastic force of the spring 806 keeps the ejector pin 807 in its normal reset state. A sliding frame 808 is slidably fitted on the outer wall of 05. The sliding frame 808 is used to push the ejector pin 807 to move axially to open the valve core of the tire valve. To accommodate tire valves of different specifications, the front end of the connecting assembly 8 is detachably connected to an air nozzle by a thread. The air nozzle can be any one of the first air nozzle 801, the second air nozzle 802, and the third air nozzle 803. To enhance the airtightness during docking and prevent gas leakage from affecting the measurement accuracy, a sealing ring 804 is also fitted around the root of the air nozzle to ensure the wide applicability and high reliability of the connection.

[0029] To facilitate the hanging and storage of the tire pressure gauge when not in use, a connecting rope 4 is connected to the handle 2, and a connecting ring 5 is connected to the end of the connecting rope 4. In order to effectively position the connecting ring 5 and prevent the connecting ring 5 from sliding freely on the connecting rope 4, a fixing ring 6 is also slidably set on the connecting rope 4. By adjusting the position of the fixing ring 6, the connecting ring 5 can be easily fixed in the desired position.

[0030] Working principle: When performing tire pressure testing, the operator first moves the entire device to the tire to be tested by holding the handle 2 and observes the position and angle of the tire valve. Then, the operator operates the rotating block 702 in the rotating assembly 7. The rotating block 702 drives the rotating shaft 703 to rotate, and the rotating plate 704 fixed on the rotating shaft 703 rotates synchronously. The rotation of the rotating plate 704 changes the spatial orientation of the connecting pipe 705, and through the flexible deformation of the hose 706, the connecting assembly 8 is finally adjusted to a precise angle that is convenient for docking with the tire valve.

[0031] When the connecting component 8 is aligned with and pressed against the tire valve, the sliding frame 808 is pushed forward by the force, pushing the ejector pin 807. With the help of the elastic force of the spring 806, the ejector pin 807 opens the valve core of the tire valve. At this time, the air inside the tire is transmitted to the pressure gauge 1 through the air passage formed by the valve, connecting component 8, hose 706, connecting pipe 705, rotating component 7 and air pipe 3. The pressure gauge 1 then displays the current tire pressure value. After the test is completed, the external force is removed, the ejector pin 807 is reset under the action of the spring 806, the tire valve closes, and the measurement is completed.
