[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1 As shown, the present application provides an inner tube tire pressure detection device, comprising a chassis 1, and a tightening assembly 2 is arranged on the chassis 1, and the tightening assembly 2 is used to tighten the inner tube;

[0025] like Figure 1-Figure 2 As shown, the tightening assembly 2 includes a tightening portion 21 mounted on the chassis 1, and the tightening portion 21 is an existing three-jaw chuck. The specific structure and principle are not described in detail here. At the same time, multiple groups of slide grooves (not shown in the figure) are opened on the tightening portion 21, and slide rods 24 are slidably arranged inside the multiple groups of slide grooves. At the same time, a support plate 22 is fixedly installed at one end of the slide rod 24 away from the slide groove, and a spring 23 is commonly arranged between the support plate 22 and the tightening portion 21;

[0026] The inner tube is placed on the tightening part 21. Driven by the tightening part 21, the slide bar 24 drives the support plate 22 and the spring 23 to move. When the support plate 22 contacts the inner tube, the support plate 22 drives the slide bar 24 to move toward the inside of the slide groove. At this time, the spring 23 is compressed to buffer the tightening force during tightening to prevent the inner tube from being damaged due to excessive tightening force. In addition, it can also be suitable for tightening inner tubes of different sizes.

[0027] At the same time, a detection component 4 is arranged on the chassis 1, and the detection component 4 is used to detect the tire pressure of the inner tube;

[0028] like Figure 1 As shown, the detection assembly 4 includes a mounting frame 42 fixedly mounted on the chassis 1, and a pressure gauge 41 is fixedly mounted on the mounting frame 42. After the inner tube is tightened, the valve of the inner tube is connected to the pressure gauge 41 through a connecting hose, and then the air pressure inside the inner tube is detected by the pressure gauge 41;

[0029] At the same time, an adjustment component 3 is fixedly mounted on the chassis 1, and the adjustment component 3 is used to adjust the angle at which a sharp object pierces the inner tube;

[0030] like Figure 1 and Figure 3 As shown, the adjustment component 3 includes a cylinder 31 fixedly mounted on the chassis 1, and a push rod 32 is fixedly mounted on the output end of the cylinder 31, and a mounting seat 33 is fixedly mounted on the end of the push rod 32 away from the cylinder 31, and a rotating base 34 is fixedly mounted on the mounting seat 33. It should be noted that the rotating base 34 can be divided into a rotating part and a fixed part. The rotating part can be a rotating structure driven by a motor. When in use, the motor is installed inside the fixed part, and a rotating shaft is fixedly mounted on the output end of the motor. The rotating shaft and the rotating part are fixedly connected, so that the rotating part is driven to rotate by the motor;

[0031] Driven by the cylinder 31, the push rod 32 drives the mounting seat 33 and rotates to move toward the outer surface of the inner tube, so as to adapt to inner tubes of different sizes. After moving to the specified position, the angle between the mounting seat 33 and the outer surface of the inner tube is adjusted by the rotating part of the rotating base 34 to adjust the angle when sharp objects pierce the inner tube.

[0032] At the same time, a pushing component 5 is fixedly installed on the adjusting component 3, and the pushing component 5 is used to push sharp objects into the inner tube;

[0033] like Figure 1 and Figure 3 As shown, the pushing assembly 5 includes an electric cylinder 51 fixedly mounted on a rotating seat, and a push rod 52 is fixedly mounted on the output end of the electric cylinder 51, and a clamping portion 53 is fixedly mounted on the end of the push rod 52 away from the electric cylinder 51, and a sharp portion is provided on the clamping portion 53, and the sharp portion can be a nail, so as to facilitate piercing the inner tube. It should be noted that the clamping portion 53 is an existing pneumatic finger, and the specific structure and principle are not described in detail here;

[0034] After the preliminary tire pressure detection is completed, the nail is clamped under the drive of the clamping part 53, and then the push rod 32 is driven by the electric cylinder 51 to move, so as to drive the clamping part 53 to move, thereby synchronously driving the nail to move and pierce the inner tube. At this time, by observing the data changes of the air pressure gauge 41 of the detection component 4, the leakage speed and degree of the inner tube can be intuitively reflected, so as to obtain the air pressure data of the inner tube after the inner tube is punctured in real conditions, so as to facilitate its evaluation later;

[0035] To summarize, when testing the inner tube pressure, the inner tube is tightened and fixed by the tightening component 2, and then the air pressure inside it is preliminarily tested by the detection component 4, and then the angle between the pushing component 5 and the inner tube is adjusted by the adjustment component 3 to adjust the angle of the nail penetrating the inner tube to obtain more data. After the adjustment is completed, the pushing component 5 fixes the nail and penetrates it into the inner tube. At this time, the data of the pressure gauge 41 is recorded and observed to obtain more data to ensure that the results of the subsequent analysis are more accurate.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
