[0022] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0023] In this disclosure, unless otherwise indicated, directional terms such as "upper, lower, top, and bottom" generally refer to the upper, lower, top, and bottom positions of the corresponding component in the direction of gravity when in use. "Inside" and "outside" refer to the inside and outside relative to the outline of the component or structure itself. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same elements.

[0024] The present disclosure provides a cylinder leak detection device, comprising: an installation box 1; an air pipe 2, which is arranged in the installation box 1 and has both ends extending outside the installation box 1, one end of the air pipe 2 is used to be connected to the air inlet of the cylinder, and the other end is used to be connected to the air source; a control valve 6, which is arranged on the air pipe 2; and a pressure detection device 5, which is arranged on the air pipe 2 and has a display end located outside the installation box 1.

[0025] Through the above technical solution, the gas pipe 2 is arranged in the installation box 1 for easy carrying. One end of the gas pipe 2 is used to connect to the gas source, and the other end is connected to the cylinder. When in use, open the air inlet valve and control valve 6 of the cylinder, and supply gas to the cylinder through the gas source. After the gas supply is completed, close the control valve 6 and observe whether the reading of the pressure detection device 5 changes to detect whether the cylinder is leaking. For example, the pressure detection device 5 is a pressure gauge or a pressure meter.

[0026] As an optional implementation, Figure 1-2 As shown, the control valve 6 can be constructed as any suitable valve body. For example, in the present disclosure, the control valve 6 is constructed as a solenoid valve, which is easy to control. A switch 7 is connected to the solenoid valve, and the switch 7 is set on the outer wall of the installation box 1. The opening and closing of the solenoid valve are controlled by the switch 7. For ease of use, the switch 7 can be set on the top of the installation box 1, and a battery for powering the solenoid valve is set on the installation box 1.

[0027] As an optional implementation, Figure 1-2 As shown, the cylinder leak detection device also includes a wire clamping device 4, which is connected to the inner wall of the installation box 1 and the gas pipe 2 to fix the gas pipe 2 in the installation box 1 to prevent the gas pipe 2 from moving at will.

[0028] Optionally, the side wall of the installation box 1 is constructed as a metal wall, and the wire-gripping device 4 includes a magnet 41 adsorbed on the metal wall and a metal ring 42 sleeved on the outside of the gas pipe 2. At least two metal rings 42 are provided at intervals. The magnet 41 is adsorbed on the inner wall of the installation box 1, and then the metal ring 42 is adsorbed on the magnet 41 to fix the gas pipe 2. The magnet 41 is used because, on the one hand, the magnet 41 is easy to install and remove, and on the other hand, the magnet 41 can be moved to facilitate adjustment of the position of the gas pipe 2. In other embodiments, the wire-gripping device 4 can also be a clamp or hook provided on the inner wall of the installation box 1.

[0029] As an optional implementation, Figure 1-3 As shown, a through hole 12 is provided on the side wall of the installation box 1 for the gas pipe 2 to pass through. The gas pipe 2 is constructed as a flexible hose. The part of the gas pipe 2 located in the installation box 1 is in a bent state so that the end of the gas pipe 2 can be extended or retracted. The end of the gas pipe 2 is provided with a limiter 13 with a diameter larger than the aperture of the through hole 12. The gas pipe 2 is pulled out when in use, and the gas pipe 2 is retracted into the installation box 1 after use, which is convenient for carrying and prevents the gas pipe 2 from extending out of the installation box 1 and getting in the way. The limiter 13 can prevent the end of the gas pipe 2 from entering the installation box 1, which is inconvenient for next use.

[0030] Alternatively, as Figure 3 As shown, a joint 3 is provided at the end of the gas pipe 2, and the joint 3 is used to connect the gas source and the cylinder. A limiter 13 is circumferentially arranged on the outside of the joint 3 to prevent the joint 3 from entering the installation box 1.

[0031] In addition, if Figure 3 As shown, the cylinder leak detection device further includes a fixing device 10 , which is disposed at the through hole 12 to fix the joint 3 . The fixing device 10 is used to fix the joint 3 at the through hole 12 to prevent the joint 3 from detaching from the through hole 12 .

[0032] Alternatively, as Figure 3 As shown, a mounting groove 11 extending in the radial direction of the through hole 12 is provided on the hole wall of the through hole 12, and the fixing device 10 includes a spring 101 and a card bead 102. One end of the spring 101 extends into the mounting groove 11 and is connected to the bottom of the mounting groove 11, and the other end is connected to the card bead 102. The card bead 102 at least partially extends out of the mounting groove 11, and an annular card groove 31 for engaging with the card bead 102 is provided on the connector 3 along the circumference. When the gas pipe 2 needs to be retracted, the connector 3 is inserted into the through hole 12 to squeeze the card bead 102, and the spring 101 contracts. When the position of the annular card groove 31 corresponds to the card bead 102, the card bead 102 extends into the annular card groove 31 to clamp the connector 3, which facilitates the fixing and removal of the connector 3. The annular card groove 31 allows the connector 3 to be engaged with the card bead 102 at any angle.

[0033] As an optional implementation, Figure 1-2 As shown, the installation box 1 is constructed as a suitcase, and a handle 8 is provided on the top of the suitcase. The suitcase is small and easy to carry.

[0034] As an optional implementation, Figure 1-2 As shown, the gas pipe 2 is arranged in the upper part of the installation box 1, and there is a placement space 14 for placing tools under the gas pipe 2. A door body 9 that can be opened and closed is provided on one side of the installation box 1. The installation box 1 can also be used to place tools that need to be used while installing the gas pipe 2. The installation box 1 can be opened and closed by the door body 9 to take out and place the tools, and the gas pipe 2 can be installed and removed at the same time.

[0035] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0037] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
