Specific embodiments

[0022] The following is a specific introduction to the present invention in combination with the attached drawings and specific embodiments.

[0023] Please refer to Figures 1-7 , the present invention provides a technical solution: a tire pressure detection device for an automobile tire, including a working plate 1, two symmetric working frames 2 are fixedly connected to the upper surface of the working plate 1, an automobile tire 20 is arranged between the two working frames 2, first cylinders 3 are fixedly connected to the outer sides of the two working frames 2, a pressure measurement component is arranged on the side of the first cylinder 3, a pushing component for pushing the automobile tire 20 away is arranged on the side of the working frame 2, a transportation component for transporting the detected automobile tire 20 is arranged at the rear of the working plate 1, and a feeding component for feeding the automobile tire 20 is arranged above the transportation component. First, the feeding component feeds the automobile tire 20 into the working frame 2, then the pressure measurement component measures the pressure of the automobile tire 20, the measured automobile tire is pushed by the pushing component to the transportation component, and finally the transportation component transports the detected automobile tire 20 away.

Then, the connecting plate 4 drives the detection plate 7 to move through the connecting shaft 5 to squeeze the automobile tire 20. Then, the first cylinder 3 continues to drive 7 to squeeze the tire through the connecting plate 4 and the connecting shaft 5, and observe which one of the three indicating blocks 6 the light emitted by the laser block 8 irradiates on. As Figure 2 shown, if the laser block 8 irradiates on the middle indicating block 6, it means that the air pressure of the automobile tire 20 is the standard air pressure. If the laser block 8 irradiates on the indicating block 6 close to the detection plate 7, it means that the air pressure of the automobile tire 20 is too high, and the air pressure of the automobile tire 20 needs to be adjusted for convenient use. If the laser block 8 irradiates on the indicating block 6 close to the connecting plate 4, it means that the air pressure of the automobile tire 20 is too low, which also does not meet the standard of the air pressure of the automobile tire 20, and the air pressure of this automobile tire 20 needs to be adjusted to reach the normal value for convenient use.

[0026] By the laser irradiating on the indicating blocks 6 at different positions, the air pressure condition of the automobile tire 20 can be clearly judged, which is simple, intuitive and convenient to operate.

The first toothed rod 15 drives the connecting rod 16 to move backward. The connecting rod 16 drives the push rod 18 to move backward. Without the obstruction of the baffle 10, the push rod 18 drives the push plate 19 to move backward, so that the vehicle tire 20 moves backward and falls on the transmission table 22, and the detected vehicle tire 20 is conveyed away; It is ensured that after the air pressure of the vehicle tire 20 is detected, it is not necessary for the staff to remove the tire from the device, avoiding the injury to the staff during the process of taking the tire due to the large weight of the vehicle tire 20.

[0037] Step 3: Start the pushing component to push the vehicle tire 20 that has been measured for pressure onto the transportation component; Step 4: The transportation component transports the vehicle tire 20 that has been detected away.

[0038] Working principle: Start the first cylinder 3, the first cylinder 3 drives the connecting plate 4 to move towards the working frame 2, and then the connecting plate 4 drives the detection plate 7 to move through the connecting shaft 5 to squeeze the vehicle tire 20. Then the first cylinder 3 continues to drive 7 to squeeze the tire through the connecting plate 4 and the connecting shaft 5, and observe which one of the three indicating blocks 6 the light emitted by the laser block 8 shines on; As Figure 2 shown, if the laser block 8 shines on the middle indicating block 6, it means that the air pressure of the vehicle tire 20 is the standard air pressure; If the laser block 8 shines on the indicating block 6 close to the detection plate 7, it means that the air pressure of the vehicle tire 20 is too high, and the air pressure of the vehicle tire 20 needs to be adjusted for convenient use; If the laser block 8 shines on the indicating block 6 close to the connecting plate 4, it means that the air pressure of the vehicle tire 20 is too low, which also does not meet the standard of the air pressure of the vehicle tire 20, and the air pressure of this vehicle tire 20 needs to be adjusted to reach the normal value for convenient use.

[0039] By the laser shining on the indicating blocks 6 at different positions, the air pressure condition of the vehicle tire 20 can be clearly judged, which is simple, intuitive and convenient to operate.

[0040] The present invention does not require connecting an additional pressure measuring device to the air injection hole of the vehicle tire 20, always ensuring that the air pressure inside the vehicle tire 20 is the same before and after the air pressure detection. There is no need to consider whether it is aligned with the air injection port, avoiding contact with the air injection port of the vehicle tire 20, and avoiding the air leakage that may occur during the connection or removal of the traditional pressure measuring device from the tire with normal air pressure, which may cause the tire pressure inside the vehicle tire 20 to decrease; After the air pressure of the vehicle tire 20 is detected, the electric double-headed rotating shaft 13 is started. First, the electric double-headed rotating shaft 13 rotates to drive the winding roller 12 to rotate. The winding roller 12 winds up the traction rope 11, and the winding roller 12 winds up the remaining traction rope 11 on the second winding roller 9 through the traction rope 11, so as to drive the second winding roller 9 to rotate. After the second winding roller 9 rotates, it drives the baffle 10 to rotate clockwise by ninety degrees; A torsion spring is provided inside the second winding roller 9 for resetting.

The first toothed rod 15 drives the connecting rod 16 to move backward. The connecting rod 16 drives the push rod 18 to move backward. The push rod 18, without the obstruction of the baffle 10, pushes the push plate 19, causing the vehicle tire 20 to move backward and fall onto the transmission table 22, transporting the vehicle tire 20 that has completed the detection away; It is ensured that after the air pressure of the vehicle tire 20 is detected, it is not necessary for the staff to remove the tire from the device, avoiding the situation that due to the relatively large weight of the vehicle tire 20, the staff may be accidentally injured during the process of taking it. Thus, it further ensures that the vehicle tire 20 can be conveniently and quickly removed, and the safety of the staff can be guaranteed, liberating the labor force.
