Description

Technical Field

[0001] This utility model relates to the field of automobile tire technology, specifically to a device for measuring automobile tire pressure. Background Technology

[0002] Tire pressure is a crucial indicator during tire use. It is essential to ensure that the tire pressure matches the manufacturer's recommended pressure. Otherwise, whether the tire pressure is too high or too low, it will significantly damage the tire's lifespan. This necessitates the use of a tire pressure measuring device to test the tire pressure. However, existing tire pressure measuring devices have some shortcomings in their use. To meet market needs, a new device for measuring automotive tire pressure is required.

[0003] The existing measuring device is not securely assembled, which reduces its effectiveness in testing tire pressure. Furthermore, its sealing performance needs improvement, as it cannot achieve a high seal between the copper head and the tire valve, resulting in inaccurate test results. In addition, the device lacks sufficient impact resistance and durability, leaving the pressure gauge surface vulnerable to damage from impacts. Utility Model Content

[0004] The purpose of this utility model is to provide a measuring device for automobile tire pressure, in order to solve the problems mentioned in the background art, such as insufficiently stable assembly, inadequate sealing and leak-proof performance, and insufficient impact resistance and durability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for automobile tire pressure, comprising a measuring device body, the measuring device body including a pressure gauge, a fixed tube, a vent valve, an extended rubber tube, and a copper head. The fixed tube is installed at the bottom of the pressure gauge, the vent valve is installed on the surface of the fixed tube, the extended rubber tube is provided on the surface of the fixed tube, the copper head is installed on the surface of the extended rubber tube away from the fixed tube, a tire valve is provided on one side of the extended rubber tube, an anti-drop protection mechanism is provided on the surface of the pressure gauge, a stable assembly mechanism is provided on the surfaces of the extended rubber tube and the fixed tube, and a sealing and leak-proof mechanism is provided on the surfaces of the extended rubber tube and the tire valve.

[0006] Preferably, a fixing screw is installed on the surface of the extended hose, and the top end of the fixing screw extends into the interior of the fixing tube and is threadedly engaged with the inner wall of the fixing tube.

[0007] Preferably, the anti-fall protection mechanism includes a rubber protective sleeve, a rubber protrusion strip, mounting parts and a rubber pad. The surface of the barometer is covered with a rubber protective sleeve, and four sets of mounting parts are arrayed on the surface of the rubber protective sleeve. The surface of the mounting parts is in contact with the surface of the barometer.

[0008] Preferably, the surface of the rubber protective sleeve is equipped with multiple sets of rubber protrusions, and the rubber protective sleeve and rubber protrusions are used to protect the surface of the pressure gauge. The inner wall of the rubber protective sleeve is equipped with a rubber pad, and the inner wall of the rubber pad is in contact with the surface of the pressure gauge.

[0009] Preferably, the stabilizing assembly mechanism includes an L-shaped plate, an anti-slip pad, positioning clips and positioning slots, and four sets of L-shaped plates are arrayed on the surface of the extended tube. The inner wall of the L-shaped plate is equipped with an anti-slip pad, and the surface of the anti-slip pad is in close contact with the surface of the fixed tube.

[0010] Preferably, the inner wall of the L-shaped plate is equipped with a positioning clip, and the surface of the fixing tube is provided with a positioning slot for engaging with the positioning clip.

[0011] Preferably, the sealing and leak-proof mechanism consists of a sealing ring, a sealing gasket, a silicone gasket, an elastic block, and a fixing groove. The surface of the extended tubing is fitted with a sealing ring, and the inner wall of the sealing ring is fitted with a sealing gasket.

[0012] Preferably, a silicone pad is installed on the inner wall of the sealing gasket, the surface of the silicone pad is in contact with the surface of the tire valve, multiple sets of elastic locking blocks are installed on the inner wall of the silicone pad, and a fixing groove is opened on the surface of the tire valve for engaging with the elastic locking blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the measuring device for automobile tire pressure not only makes the assembly between the fixed tube and the extended rubber tube more secure during use, resulting in better testing effect of the measuring device for automobile tire pressure, and provides a high sealing effect between the copper head and the tire valve, making the test results more accurate, but also protects the surface of the pressure gauge during use, preventing damage to the surface of the pressure gauge from impacts, making the measuring device more shock-resistant and durable;

[0014] 1. With a stable assembly mechanism, when the extended hose is assembled on the surface of the fixed tube, the L-shaped plate on the surface of the extended hose moves to one side of the fixed tube, and the anti-slip pad on the inner wall of the L-shaped plate moves to be in close contact with the surface of the fixed tube. At this time, the positioning clip on the inner wall of the L-shaped plate automatically engages with the corresponding positioning slot. The engagement action of the positioning clip and the positioning slot can reinforce the assembled extended hose and the fixed tube, making the extended hose more firmly assembled on the surface of the fixed tube. This realizes the function of stable assembly of the measuring device, making the assembly between the fixed tube and the extended hose more secure when the measuring device is used, and making the measuring device better at testing the tire pressure of automobile tires.

[0015] 2. By incorporating a sealing and leak-proof mechanism, when the copper head is inserted into the tire valve, the sealing ring on the extended hose moves to the surface of the tire valve, and the silicone pad on the inner wall of the sealing ring moves to contact the surface of the tire valve. The elastic block on the inner wall of the silicone pad automatically engages with the fixed slot. The engagement of the elastic block and the fixed slot ensures a tight connection between the sealing ring and the tire valve. The combined action of the sealing ring, sealing pad, and silicone pad seals the connection between the copper head and the tire valve, preventing gas inside the tire valve from leaking out through the gap between the copper head and the tire valve, thus affecting the accuracy of the test results. This achieves the sealing and leak-proof function of the measuring device, resulting in a high sealing effect between the copper head and the tire valve during use, making the test results more accurate.

[0016] 3. By incorporating an anti-drop protection mechanism, a rubber protective sleeve is fitted onto the surface of the barometer. The mounting parts on the surface of the rubber protective sleeve move to contact the surface of the barometer, securing the sleeve in place. The inner wall of the rubber pad on the inner wall of the protective sleeve moves to contact the surface of the barometer. The rubber pad protects the surface of the barometer. The combined action of the rubber protrusions and the protective sleeve enhances the barometer's drop resistance. When the barometer is accidentally dropped, the rubber protrusions on the protective sleeve first contact the ground, absorbing the impact force on the protective sleeve and the barometer surface. The combined effect of the protective sleeve and the rubber pad protects the surface of the barometer, achieving a drop-resistant and durable measuring device. This protects the surface of the barometer during use, preventing damage from impacts and making the measuring device more durable and resistant to drops. Attached Figure Description

[0024] The structure of the measuring device for automobile tire pressure provided by this utility model is as follows: Figure 1 and Figure 2As shown, the device includes a measuring device body 1, which includes a pressure gauge 11, a fixed tube 12, a vent valve 13, an extended hose 14, and a copper head 15. The fixed tube 12 is installed at the bottom of the pressure gauge 11, the vent valve 13 is installed on the surface of the fixed tube 12, the extended hose 14 is provided on the surface of the fixed tube 12, and a fixing screw tube 16 is installed on the surface of the extended hose 14. The top end of the fixing screw tube 16 extends into the interior of the fixed tube 12 and is threaded into the inner wall of the fixed tube 12. The copper head 15 is installed on the surface of the extended hose 14 away from the fixed tube 12, and a tire valve 17 is provided on one side of the extended hose 14. The copper head 15 is inserted into the interior of the tire valve 17.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, the surface of the barometer 11 is provided with an anti-drop protection mechanism 2. The anti-drop protection mechanism 2 includes a rubber protective sleeve 21, rubber protrusions 22, mounting parts 23, and a rubber pad 24. The surface of the barometer 11 is covered with a rubber protective sleeve 21. Four sets of mounting parts 23 are arrayed on the surface of the rubber protective sleeve 21. The surface of the mounting parts 23 is in contact with the surface of the barometer 11. Multiple sets of rubber protrusions 22 are arrayed on the surface of the rubber protective sleeve 21. The rubber protective sleeve 21 and the rubber protrusions 22 are used to protect the surface of the barometer 11. A rubber pad 24 is installed on the inner wall of the rubber protective sleeve 21. The inner wall of the rubber pad 24 is in contact with the surface of the barometer 11.

[0026] In practice, the rubber protective sleeve 21 is fitted onto the surface of the barometer 11. The mounting part 23 on the surface of the rubber protective sleeve 21 moves to contact the surface of the barometer 11, and the rubber protective sleeve 21 is snapped onto the surface of the barometer 11. At this time, the inner wall of the rubber pad 24 on the inner wall of the rubber protective sleeve 21 moves to contact the surface of the barometer 11. Under the action of the rubber pad 24, the surface of the barometer 11 can be protected. Under the combined action of the rubber protrusion strip 22 and the rubber protective sleeve 21, the impact resistance of the barometer 11 can be improved. When the barometer 11 is accidentally dropped, the rubber protrusion strip 22 on the surface of the rubber protective sleeve 21 will first contact the ground. Under the action of the rubber protrusion strip 22, the impact force on the surface of the rubber protective sleeve 21 and the barometer 11 can be damped. With the cooperation of the rubber protective sleeve 21 and the rubber pad 24, the surface of the barometer 11 can be protected, so as to realize the function of the measuring device being impact-resistant and durable.

[0027] Furthermore, such as Figure 2 and Figure 4As shown, the extended hose 14 and the fixed tube 12 are provided with a stabilizing assembly mechanism 3. The stabilizing assembly mechanism 3 includes an L-shaped plate 31, an anti-slip pad 32, a positioning clip 33, and a positioning slot 34. Four sets of L-shaped plates 31 are arrayed on the surface of the extended hose 14. The inner wall of the L-shaped plate 31 is provided with an anti-slip pad 32. The surface of the anti-slip pad 32 is in close contact with the surface of the fixed tube 12. The inner wall of the L-shaped plate 31 is provided with a positioning clip 33. The surface of the fixed tube 12 is provided with a positioning slot 34 for engaging with the positioning clip 33.

[0028] During implementation, when the extended hose 14 is assembled on the surface of the fixed tube 12, the L-shaped plate 31 on the surface of the extended hose 14 moves to one side of the fixed tube 12, and the anti-slip pad 32 on the inner wall of the L-shaped plate 31 moves to be in close contact with the surface of the fixed tube 12. At this time, the positioning clip 33 on the inner wall of the L-shaped plate 31 automatically engages with the corresponding positioning slot 34. Under the engaging action of the positioning clip 33 and the positioning slot 34, the assembled extended hose 14 and the fixed tube 12 can be reinforced, making the extended hose 14 more firmly assembled on the surface of the fixed tube 12, so as to realize the function of stable assembly of the measuring device.

[0029] Furthermore, such as Figure 2 and Figure 5 As shown, the extended rubber hose 14 and the surface of the tire valve 17 are provided with a sealing and leak-proof mechanism 4. The sealing and leak-proof mechanism 4 consists of a sealing ring 41, a sealing gasket 42, a silicone gasket 43, an elastic block 44, and a fixing groove 45. The surface of the extended rubber hose 14 is fitted with a sealing ring 41. The inner wall of the sealing ring 41 is fitted with a sealing gasket 42. The inner wall of the sealing gasket 42 is fitted with a silicone gasket 43. The surface of the silicone gasket 43 is in contact with the surface of the tire valve 17. The inner wall of the silicone gasket 43 is fitted with multiple sets of elastic blocks 44. The surface of the tire valve 17 is provided with a fixing groove 45 for engaging with the elastic blocks 44.

[0030] During implementation, when the copper head 15 is inserted into the tire valve 17, the sealing ring 41 on the surface of the extended tubing 14 moves to the surface of the tire valve 17, and the silicone pad 43 on the inner wall of the sealing ring 41 moves to contact the surface of the tire valve 17. At this time, the elastic locking block 44 on the inner wall of the silicone pad 43 automatically locks into the fixed slot 45. Under the locking action of the elastic locking block 44 and the fixed slot 45, the tightness of the connection between the sealing ring 41 and the tire valve 17 can be ensured. Under the joint action of the sealing ring 41, the sealing pad 42 and the silicone pad 43, the connection between the copper head 15 and the tire valve 17 can be sealed, preventing the gas inside the tire valve 17 from leaking out through the gap between the copper head 15 and the tire valve 17 and affecting the accuracy of the test results, so as to realize the function of sealing and preventing air leakage of the measuring device.

[0031] Working principle: When using, first place the measuring device body 1 in the designated position. The user places the extension hose 14 on the surface of the fixed tube 12, and then loosens the extension hose 14, so that the extension hose 14 drives the fixed screw tube 16 to move into the interior of the fixed tube 12. With the threaded engagement between the fixed screw tube 16 and the inner wall of the fixed tube 12, the extension hose 14 is assembled on the surface of the fixed tube 12. The air release valve 13 is operated to release air from the measuring device body 1 and return it to zero. Then, the user connects the copper head 15 on the surface of the extension hose 14 with the tire valve 17 of the car tire. The copper head 15 is gently pressed to allow it to enter the interior of the tire valve 17. The copper head 15 is kept aligned with the tire valve 17 and there is no air leakage. When the pointer of the pressure gauge 11 stabilizes at the highest point, the value is read to obtain the tire pressure of the car tire.

[0032] Subsequently, when the extended hose 14 is assembled onto the surface of the fixed tube 12, the L-shaped plate 31 on the surface of the extended hose 14 moves to one side of the fixed tube 12, and the anti-slip pad 32 on the inner wall of the L-shaped plate 31 moves to be in close contact with the surface of the fixed tube 12. At this time, the positioning clip 33 on the inner wall of the L-shaped plate 31 automatically engages with the corresponding positioning slot 34. Under the engaging action of the positioning clip 33 and the positioning slot 34, the assembled extended hose 14 and the fixed tube 12 can be reinforced, making the extended hose 14 more firmly assembled onto the surface of the fixed tube 12, so as to realize the function of stable assembly of the measuring device. This makes the assembly between the fixed tube 12 and the extended hose 14 more secure when the measuring device is used, and makes the measuring device perform better in testing the tire pressure of automobile tires.

[0033] Subsequently, when the copper head 15 is inserted into the tire valve 17, the sealing ring 41 on the surface of the extended tubing 14 moves to the surface of the tire valve 17, and the silicone pad 43 on the inner wall of the sealing ring 41 moves to contact the surface of the tire valve 17. At this time, the elastic block 44 on the inner wall of the silicone pad 43 automatically engages with the fixed slot 45. Under the engaging action of the elastic block 44 and the fixed slot 45, the tightness of the connection between the sealing ring 41 and the tire valve 17 can be ensured. Under the combined action of the sealing ring 41, the sealing pad 42 and the silicone pad 43, the connection between the copper head 15 and the tire valve 17 can be sealed, preventing the gas inside the tire valve 17 from leaking out through the gap between the copper head 15 and the tire valve 17 and affecting the accuracy of the test results. This achieves the function of sealing and preventing air leakage of the measuring device, so that the measuring device can achieve a high sealing effect between the copper head 15 and the tire valve 17 when in use, making the test results of the measuring device more accurate when in use.

[0034] Subsequently, the rubber protective sleeve 21 is fitted onto the surface of the pressure gauge 11. The mounting part 23 on the surface of the rubber protective sleeve 21 moves to contact the surface of the pressure gauge 11, securing the rubber protective sleeve 21 onto the surface of the pressure gauge 11. At this time, the inner wall of the rubber pad 24 on the inner wall of the rubber protective sleeve 21 moves to contact the surface of the pressure gauge 11. Under the action of the rubber pad 24, the surface of the pressure gauge 11 can be protected. The combined action of the rubber protrusion 22 and the rubber protective sleeve 21 can improve the impact resistance of the pressure gauge 11. When the pressure gauge 11 is accidentally dropped, the rubber protective sleeve... The rubber protrusions 22 on the surface of the gauge 11 first come into contact with the ground. Under the action of the rubber protrusions 22, the impact force on the surface of the rubber protective sleeve 21 and the barometer 11 can be damped. With the cooperation of the rubber protective sleeve 21 and the rubber pad 24, the surface of the barometer 11 can be protected, so as to realize the function of the measuring device being drop-resistant and durable. This allows the measuring device to protect the surface of the barometer 11 during use, preventing damage to the surface of the barometer 11 when it is hit, making the measuring device more drop-resistant and durable, and finally completing the use of the measuring device.
