Description

Technical Field

[0001] This utility model relates to the field of tire pressure detection technology, specifically a tire pressure gauge with a restraint structure. Background Technology

[0002] Tire pressure gauges are specialized tools used to measure tire pressure in vehicles. They are mainly divided into three types: pen type, mechanical pointer type, and electronic digital display type. Among them, electronic digital display type has the characteristics of accurate measurement and convenient operation. Its working principle is to connect the tire internal pressure through the valve core, and convert the pressure value into a scale pointer or digital display with the help of sensors or mechanical structures. Abnormal tire pressure can easily lead to a shortened tire life: too low pressure will cause increased tire deformation, fatigue of the cord layer and abnormal wear of the tire shoulder, while too high pressure will cause excessive stretching of the cord, accelerated wear of the tire crown and the risk of tire blowout.

[0003] Due to the wide variety of car models, the types of tires used will also vary. Depending on the type of valve used on the tire, a corresponding tire pressure gauge needs to be selected before it can be connected to the valve for testing, which is very inconvenient. Furthermore, during testing, it is necessary to manually connect the gauge and maintain the correct posture, which is too cumbersome. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tire pressure gauge with a restraint structure, which has the advantages of easy replacement of the connecting pipe and convenient testing, avoiding the problems of multiple tire pressure gauge models and cumbersome manual connection.

[0005] To facilitate the replacement of the connecting pipe and make inspection convenient, this utility model provides the following technical solution:

[0006] A tire pressure gauge with a restraint structure includes a detection assembly, wherein a flexible tube is fixedly connected to the side wall of the detection assembly, and further includes:

[0007] A connecting ring is fixedly connected to the end of the hose. A rotating ring is rotatably connected to the inner wall of the connecting ring. A connecting tube is snapped into the side wall of the rotating ring, and the outer wall of the connecting tube is in contact with the inner wall of the connecting ring. A connecting pipe is fixedly connected to the end of the connecting tube. A first locking post is slidably connected to the inner wall of the connecting tube, and the first locking post extends into the inner cavity of the rotating ring. A connecting plate is fixedly connected to the bottom end of the first locking post. A second locking post is fixedly connected to the side wall of the connecting plate, and the second locking post penetrates the connecting tube. A first spring is fixedly connected between the connecting plate and the connecting tube.

[0008] According to some embodiments, mounting brackets are fixedly connected to both side walls of the connecting ring, a rotating plate is rotatably connected to the inner wall of the mounting bracket, and the rotating plate extends to the outside of the connecting pipe. A pressure block is fixedly connected to the side wall of the rotating plate, and a second spring is fixedly connected between the rotating plate and the side wall of the connecting ring.

[0009] According to some embodiments, the detection component is fixedly connected to a handle at its bottom, and the hose is made of a flexible material.

[0010] This utility model provides a tire pressure gauge with a restraint structure, which has the following beneficial effects:

[0011] The tire pressure gauge with a binding structure uses a first locking post to extend into the inner cavity of the rotating ring to complete the locking between the connecting tube and the rotating ring. The connecting tube can be replaced to replace the coupling tube, so that the detection component can detect the tire pressure of tires of different sizes. At the same time, the connecting tube and the coupling tube can be rotated to facilitate the coupling tube to connect to the valves at different positions.

[0012] This tire pressure gauge with a restraint structure allows you to press the rotating plate, causing it to rotate and move the pressure block away from the connecting pipe. At this time, the second spring is stretched and generates a rebound force. After the connecting pipe is connected to the air nozzle, the rotating plate is released. Under the rebound force of the second spring, the rotating plate drives the pressure block to rotate, and the pressure block will lock onto both sides of the air nozzle to fix the position of the connecting pipe, thus freeing up the operator's hands.

[0018] 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.

[0019] Reference Figures 1-4A tire pressure gauge with a restraint structure includes a detection component 1, a flexible tube 101 fixedly connected to the side wall of the detection component 1, and further includes:

[0020] A connecting ring 2 is fixedly connected to the end of the hose 101. A rotating ring 201 is rotatably connected to the inner wall of the connecting ring 2. A connecting tube 202 is snapped into the side wall of the rotating ring 201, and the outer wall of the connecting tube 202 is in contact with the inner wall of the connecting ring 2. A connecting tube 203 is fixedly connected to the end of the connecting tube 202. A first locking post 204 is slidably connected to the inner wall of the connecting tube 202, and the first locking post 204 extends into the inner cavity of the rotating ring 201.

[0021] A connecting plate 205 is fixedly connected to the bottom end of the first locking post 204, and a second locking post 206 is fixedly connected to the side wall of the connecting plate 205. The second locking post 206 passes through the connecting pipe 202, and a first spring 207 is fixedly connected between the connecting plate 205 and the connecting pipe 202.

[0022] It should be noted that the connecting pipe 202 is engaged with the rotating ring 201. The connecting pipe 203 can be replaced by replacing the connecting pipe 202 so that the detection component 1 can detect the tire pressure of different sizes of tires. Specifically, by pressing the second locking post 206, the second locking post 206 drives the first locking post 204 to move into the inner cavity of the connecting pipe 202 through the connecting plate 205. The first spring 207 is compressed and generates a rebound force. At this time, the connecting pipe 202 can be inserted into the inner cavity of the connecting ring 2 until the first locking post 204 moves to the rotating ring 201. Using the rebound force of the first spring 207, the first locking post 204 extends into the inner cavity of the rotating ring 201, thereby completing the engagement of the connecting pipe 202 and the rotating ring 201. At the same time, the connecting pipe 202 and the connecting pipe 203 can be rotated to facilitate the connection of the connecting pipe 203 with the valves at different positions.

[0023] Reference Figures 1-4 Mounting brackets 3 are fixedly connected to both sides of the connecting ring 2. A rotating plate 301 is rotatably connected to the inner wall of the mounting bracket 3, and the rotating plate 301 extends to the outside of the connecting pipe 203.

[0024] A pressure block 302 is fixedly connected to the side wall of the rotating plate 301, and a second spring 303 is fixedly connected between the rotating plate 301 and the side wall of the connecting ring 2.

[0025] It should be noted that when using the connecting pipe 203 to connect the air nozzle, press the rotating plate 301 to make the rotating plate 301 rotate with the mounting bracket 3 and drive the pressure block 302 away from the connecting pipe 203. At this time, the second spring 303 is stretched and generates a rebound force. After the connecting pipe 203 is connected to the air nozzle, release the rotating plate 301. Under the action of the rebound force of the second spring 303, the rotating plate 301 drives the pressure block 302 to rotate. The pressure block 302 will be locked on both sides of the air nozzle to complete the fixation of the position of the connecting pipe 203, which can free the operator's hands.

[0026] Reference Figures 1-4 The bottom of the detection component 1 is fixedly connected to a handle 4, and the hose 101 is made of flexible material;

[0027] It should be noted that: handle 4 makes it easy for staff to pick up the testing component 1, and the design of hose 101 makes hose 101 stretchable, which is convenient for testing the air nozzles at different positions.

[0028] Operating method: When connecting the nozzle with the connecting pipe 203, press the rotating plate 301, so that the rotating plate 301 rotates with the mounting bracket 3 and drives the pressure block 302 away from the connecting pipe 203. At this time, the second spring 303 is stretched and generates a rebound force. After the connecting pipe 203 is connected to the nozzle, release the rotating plate 301. Under the action of the rebound force of the second spring 303, the rotating plate 301 drives the pressure block 302 to rotate. The pressure block 302 will be locked on both sides of the nozzle to fix the position of the connecting pipe 203, which can free the operator's hands.

[0029] The connecting pipe 202 is engaged with the rotating ring 201. The connecting pipe 203 can be replaced by replacing the connecting pipe 202 so that the detection component 1 can detect the tire pressure of different sizes of tires. By pressing the second locking post 206, the second locking post 206 drives the first locking post 204 to move into the inner cavity of the connecting pipe 202 through the connecting plate 205. The first spring 207 is compressed and generates a rebound force. At this time, the connecting pipe 202 can be inserted into the inner cavity of the connecting ring 2 until the first locking post 204 moves to the rotating ring 201. Using the rebound force of the first spring 207, the first locking post 204 extends into the inner cavity of the rotating ring 201, thereby completing the engagement of the connecting pipe 202 and the rotating ring 201. At the same time, the connecting pipe 202 and the connecting pipe 203 can be rotated to facilitate the connection of the connecting pipe 203 with the valves at different positions.
