Description

Technical Field

[0001] The utility model relates to the technical field of tire pressure matching instruments, in particular to a radio frequency matching device for a tire pressure sensor. Background Art

[0002] The tire pressure matching instrument monitors tire pressure by programming the sensor ID and specifying the frequency. Its primary function is to monitor tire pressure in real time to ensure driving safety. It utilizes the sensing function of the vehicle's ABS (anti-lock braking system) system to check tire pressure by comparing tire rotations. When a tire is underinflated, its circumference decreases, resulting in a different rotation rate than other tires during driving. This triggers an alarm system, prompting the driver to promptly check and refill the tire pressure.

[0003] However, when using a tire pressure matching instrument, the connecting wire needs to be plugged into the connector of the tire pressure matching instrument. When matching the tire pressure matching instrument display screen with the sensor, the connecting wire may be pulled during the movement of the matching instrument, and the connecting wire may easily fall off from the connector, which may affect the monitoring effect of the tire pressure matching instrument.

[0004] Therefore, a tire pressure matching instrument with a stable connection is needed. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a radio frequency matching device for a tire pressure sensor. By pushing the dial block by hand, the pressure plate drives the slide rod to slide and squeezes the telescopic spring. The pressure plate is separated from the connecting wire, which makes it easy for the operator to remove the connecting wire from the connector.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0032] The pressing plate 603 is slidably connected to the fixing block 601 , and the pressing plate 603 is arranged in an L-shaped structure. When the pressing plate 603 slides to a state of contact with the connecting line 4 , the connecting line 4 can be firmly installed inside the connector 5 .

[0033] The sliding rod 605 is slidably connected to the fixed block 601 , and both ends of the telescopic spring 606 are fixedly connected to the fixed block 601 and the sliding rod 605 respectively. When the sliding rod 605 slides in the sliding groove 604 , the telescopic spring 606 can be squeezed.

[0034] The shift block 602 is located on the side wall of the pressure plate 603 away from the connector 5 , and the shift block 602 is arranged in an L-shaped structure. When the pressure plate 603 slides, it can drive the slide rod 605 to slide in the fixed block 601 .

[0035] The connector 5 is located at the bottom end of the tire pressure matching instrument body 1 , and the pressure plate 603 is slidably connected to the connecting wire 4 . When the connecting wire 4 is inserted into the inside of the connector 5 , the connecting wire 4 can be connected to the tire pressure matching instrument body 1 .

[0036] The length of the pressing plate 603 is greater than the width of the fixing block 601 , and the width of the sliding groove 604 is greater than the length of the shifting block 602 . When the shifting block 602 is pushed with a finger, the pressing plate 603 can be driven to slide in the sliding groove 604 .

[0037] The sensor slot 2 is located at the top of the tire pressure matching instrument body 1, and the two ends of the anti-collision strip 3 are arranged in an arc structure.

The bracket 702 drives the connecting rod 704 to rotate, so that the connecting rod 704 can rotate along the protrusions 701 .

[0040] The rubber pad 703 is located on the side wall of the bracket 702 away from the tire pressure matching instrument body 1. The two ends of the bracket 702 are arranged in an arc structure.

[0041] Instructions for use:

[0042] First, when installing the connecting line 4 of the tire pressure matching instrument body 1, the operator can use his fingers to push the two dial blocks 602, which are fixed to the side walls of the pressure plate 603. The pressure plate 603 is located inside the fixed block 601. The two fixed blocks 601 are symmetrically installed on both sides of the joint 5. The pressure plate 603 is fixedly connected to a slide bar 605. When the dial block 602 drives the pressure plate 603 to slide in the slide groove 604, the slide bar 605 can squeeze the telescopic spring 606 sleeved on the side wall, and the telescopic spring 60 6 is in a compressed state, the pressure plate 603 can be slid to the side away from the connector 5, and then the connecting line 4 can be plugged into the inside of the connector 5. After installation, the shift block 602 is released, and the slide bar 605 drives the pressure plate 603 to slide under the reaction force of the telescopic spring 606. The pressure plate 603 moves in the direction close to the connecting line 4, which can resist the connecting line 4 and thus firmly install the connecting line 4 in the connector 5, which is helpful to prevent the connecting line 4 from falling off from the connector 5 during the use of the tire pressure matching instrument body 1.

[0043] During use, the operator can ensure that the vehicle has been started, prepare the tire pressure detector, and ensure that the tire pressure is appropriate; rotate the bracket 702 so that it drives the connecting rod 704 to rotate inside the protrusion 701, and then the rotated bracket 702 supports the tire pressure matching instrument body 1. The side wall of the bracket 702 is fixed with a rubber pad 703. When the rubber pad 703 is in contact with the plane, the tire pressure matching instrument body 1 can be in a stable state; press and hold the SET button on the display of the tire pressure matching instrument body 1 for about 3 seconds, bring the display close to the sensor, the display will automatically receive the sensor ID, then long press the SET button, and enter the pairing interface after hearing the sound.
