[0030] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0031] See also Figure 1-Figure 7 As shown, the utility model provides a gas cylinder support for gas cylinder detection, including side panels 4 and a top panel 3, the number of side panels 4 is two and they are respectively vertically located at two side positions, a top panel 3 is horizontally fixed between the tops of the side panels 4 at the two side positions, and a gas cylinder support assembly 5 for supporting an inverted gas cylinder is installed at the bottom and below the top panel 3. Specifically, the gas cylinder support assembly 5 includes a storage sleeve 501 and a support plate 502, a plurality of storage sleeves 501 are vertically fixed to the bottom surface of the top panel 3, the upper and lower ends of the storage sleeves 501 are open, and the top openings of the storage sleeves 501 expose the top surface of the top panel 3, a support plate 502 is flatly placed between the side panels 4 at the two side positions below the storage sleeves 501, a plurality of supporting bottom covers 503 are vertically fixed to the bottom surface of the support plate 502, and the supporting bottom covers 503 and the supporting bottom covers 503 are connected to the support plate 502. The number of storage sleeves 501 corresponds and they are coaxially matched up and down. The top ends of the supporting bottom covers 503 are all open, and the top openings of the supporting bottom covers 503 expose the top surface of the support plate 502. The bottom surfaces of the supporting bottom covers 503 are coaxially provided with passage openings 504 for allowing the gas nozzles of the gas cylinders to pass through smoothly. The purpose of such a setting is to quickly complete the inverted placement of the gas cylinders by extending the inverted gas cylinders through the storage sleeves 501 and allowing the bottoms to be supported by the supporting bottom covers 503, and to enable the gas nozzles at the bottom of the gas cylinders to be immersed in the water of the water tank body 2 for air tightness testing. The inverted air tightness testing method for the gas cylinders is simple and easy to operate. It is preferred that the outer diameter of the gas cylinders to be tested and the inner diameter of the storage sleeves 501 have a clearance fit to ensure that the gas cylinders can be smoothly inverted and passed through the storage sleeves 501.

[0032] See also Figure 1-Figure 3As shown, the side plates 4 at both sides are installed with lifting drive components 1, which are fixedly connected to the lower sides of the gas cylinder support component 5 respectively, so as to drive the lower part of the gas cylinder support component 5 to be lifted and lowered by the lifting drive component 1. Specifically, the lifting drive component 1 includes a guide groove 106 and a cylinder body 101. The side plates 4 at both sides are vertically provided with guide grooves 106, and the guide grooves 106 are through grooves in the horizontal direction. The guide grooves 106 at the two sides are interspersed in a horizontal sliding manner. There are guide seats 105, and the end faces of the guide seats 105 at both sides are fixed to the corresponding side of the support plate 502, and the guide seats 105 at both sides are away from each other and the top surfaces of the parts extending out of the corresponding guide grooves 106 are vertically fixed with connecting sleeves 104, and the outer tops of the side plates 4 at both sides are away from each other are vertically fixed with cylinder bodies 101 through cylinder seats 102, and the telescopic push rods 103 at the bottom of the cylinder body 101 are vertically slid out of the cylinder seat 102 and the bottom ends are connected to the corresponding side. The connecting sleeve 104 is coaxially fixed. The advantage of this arrangement is that the distance between the support plate 502 and the top plate 3 can be adjusted by driving the lifting drive component 1 to lift the support plate 502, so that the spacing between the supporting bottom cover 503 and the storage sleeve 501 can be adjusted, which makes it easy for the supporting bottom cover 503 to cooperate with the storage sleeve 501 to perform airtightness detection on gas cylinders of different axial lengths, and also makes it easy to drive the gas cylinder to be tested in the water and taken out after the test by lifting the supporting bottom cover 503. Out of water, the outer diameter specifications of the gas cylinders of different axial lengths referred to above should remain consistent. Specifically, in the operation of the lifting drive assembly 1, the cylinder body 101 is ventilated by connecting to the external air supply pipeline, and the cylinder body 101 drives the telescopic push rod 103 to extend or retract through ventilation. During this process, the telescopic push rod 103 drives the guide seat 105 to vertically descend or ascend along the guide groove 106, and the guide seat 105 then drives the support plate 502 to vertically descend or ascend.

[0033] See also Figure 1-Figure 3As shown, the front of the side panels 4 at both sides are equipped with safety limit assemblies 6 at the lower position, which are used to safely limit the lowest position of the lifting and lowering adjustment of the gas cylinder support assembly 5. Specifically, the safety limit assemblies 6 include mounting holes 602 and limiting studs 601. The front of the side panels 4 at both sides are longitudinally provided with mounting holes 602 at the lower position, and the mounting holes 602 are vertically connected with the corresponding guide grooves 106. The mounting holes 602 are coaxially inserted with limiting studs 601 in a threaded manner, and the rear ends of the limiting studs 601 extend into the corresponding guide grooves 106. The effect of such a setting is that the rear ends of the limiting studs 601 of the safety limit assembly 6 extend into the guide grooves 106 to safely limit the extreme descending stroke of the support plate 502, which not only avoids the support plate 502 from descending too low to cause the gas nozzle at the bottom of the gas cylinder to touch the ground and damage, but also prevents the support plate 502 from accidentally falling and causing the gas nozzle at the bottom of the gas cylinder to touch the ground and damage.

[0034] See also Figure 1-Figure 3 As shown, the gas cylinder support assembly 5, the lifting drive assembly 1 and the safety limit assembly 6 are optimized as follows. Specifically, for the gas cylinder support assembly 5, the storage sleeve 501 is a cylinder, and the inner contour of the supporting bottom cover 503 is adapted to the outer contour of the bottom of the gas cylinder to be tested when it is inverted. This arrangement makes it easier for the bottom of the gas cylinder to be tested to be stably supported by the supporting bottom cover 503.

[0035] Specifically for the lifting drive assembly 1, the guide grooves 106 are all vertically arranged rectangular grooves, and the bottom ends of the telescopic push rods 103 are coaxially interference fit with the corresponding connecting sleeves 104. With such an arrangement, firstly, it is convenient for the guide seat 105 to have a good positioning and guiding design when it slides vertically along the guide grooves 106, and at the same time, it is convenient for the telescopic push rod 103 and the guide seat 105 to be quickly combined together through the connecting sleeve 104. Further, optionally, a water tank body 2 is arranged at the outer position of the side panel 4, and the bottom surfaces of the side panels 4 are fixed to the inner bottom surface of the water tank body 2. The top of the water tank body 2 is open, and the side of the water tank body 2 is fixedly connected to a drain pipe 201, so that the water in the water tank body 2 can be used to perform air tightness detection operations on the gas cylinder by injecting water into the water tank body 2.

[0036] Specifically in the safety limit assembly 6, the front end of the limit stud 601 is coaxially fixed with a handwheel 603 for easy holding. This arrangement makes it easy to drive the limit stud 601 to rotate by applying force by holding the handwheel 603, thereby enabling the limit stud 601 to be combined and disassembled with the installation hole 602.

[0037] With the above structure, specifically during the use of gas cylinder testing, since the storage sleeve 501 and the supporting bottom cover 503 of the gas cylinder bracket assembly 5 are respectively fixed to the bottom surface of the top plate 3 and the bottom surface of the support plate 502, and the support plate 502 is located below the top plate 3, the inverted gas cylinder can be quickly placed inverted by extending the inverted gas cylinder through the storage sleeve 501 and having the bottom supported by the supporting bottom cover 503, and the gas nozzle at the bottom of the gas cylinder can be immersed in the water of the water tank body 2 for air tightness testing. The inverted air tightness testing method for the gas cylinder is simple and easy to operate, and there is no need to clamp and fix the gas cylinder, which is convenient for one person to complete the air tightness testing operation of the gas cylinder. Since the lifting drive assembly 1 is installed on both sides of the support plate 502, the support plate 502 can be adjusted by the lifting drive assembly 1 to drive the lifting and adjustment of the support plate 502. The distance between the top plates 3 can be adjusted, so that the spacing between the supporting bottom cover 503 and the storage sleeve 501 can be adjusted, which makes it easier for the supporting bottom cover 503 to cooperate with the storage sleeve 501 to perform airtightness testing on gas cylinders of different axial lengths, and also makes it easier to drive the gas cylinder into the water for testing and take it out of the water after the testing by lifting the supporting bottom cover 503, which further facilitates the airtightness testing operation of the gas cylinder. In addition, since a safety limit assembly 6 is installed at the lower part of the side plate 4, the limit descending stroke of the support plate 502 can be safely limited by extending the rear end of the limit stud 601 of the safety limit assembly 6 into the guide groove 106, which not only avoids the support plate 502 from descending too low to cause the gas nozzle at the bottom of the gas cylinder to touch the ground and be damaged, but also prevents the support plate 502 from accidentally falling and causing the gas nozzle at the bottom of the gas cylinder to touch the ground and be damaged.

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
