[0020] The utility model provides a hydrogen generator for a gas chromatograph, comprising a housing 100, a body 101 and a moving assembly, wherein the moving assembly comprises a mounting base 102, a universal wheel 103, a fixing ring 104, a reinforcing member, a driving member, an abutment plate 105 and a rubber pad 106, wherein the reinforcing member comprises a reinforcing plate 107 and a reinforcing rod 108, and the driving member comprises a fixed base 109 and a hydraulic rod 110. The present invention solves the problem that the existing gas chromatograph hydrogen generator is large in size and heavy in weight, so that when moving the gas chromatograph hydrogen generator, it requires the joint efforts of multiple persons to move the gas chromatograph hydrogen generator, thereby increasing the physical exertion of the staff and the problem of low moving efficiency, and can also prevent the abutment plate 105 from clamping foreign matter when moving.

[0021] According to this specific embodiment, the main body 101 is installed on the inner side of the shell 100. The main body 101 is a hydrogen generating device recorded in the existing patent technology CN211947233U, a high-purity hydrogen generator for a gas chromatograph. The main body 101 is installed inside the shell 100. The main body 101 provides high-purity hydrogen for the gas chromatograph and increases the oxygen concentration in the laboratory. This solution enables a more convenient mobile device, while ensuring the stability of the device during use and improving the efficiency of the mobile device.

[0022] The mounting base 102 is fixedly connected to the housing 100 and is located below the housing 100. The universal wheel 103 is fixedly connected to the mounting base 102 and is located on a side of the mounting base 102 away from the housing 100. The fixing ring 104 is fixedly connected to the housing 100 and is located on a side of the housing 100 close to the mounting base 102.

The mounting base 102 is mounted on the bottom of the housing 100 by bolts, and the universal wheel 103 is mounted on the mounting base 102 away from the housing 100 by bolts. One side of the shell 100 is supported by the universal wheel 103, so that the device can be moved more conveniently, the fixing ring 104 is installed on the outside of the shell 100 by bolts, the reinforcement member is installed on the fixing ring 104, and the fixing ring 104 is more stably installed on the shell 100 through the reinforcement member, the abutment plate 105 is installed on the fixing ring 104 through the driving member, and the abutment plate 105 is driven by the driving member to move downward and abut against the ground, thereby lifting the shell 100 and making the universal wheel 103 leave the ground, so that the device can be stably placed in the designated position, thereby realizing a more convenient device movement, while ensuring the stability of the device during use and improving the efficiency of the mobile device.

[0023] Secondly, the rubber pad 106 is fixedly connected to the abutment plate 105 and is located on the side of the abutment plate 105 away from the fixing ring 104. The rubber pad 106 is installed on the side of the abutment plate 105 away from the fixing ring 104 by bolts. The rubber pad 106 increases the friction between the abutment plate 105 and the ground to prevent the device from moving during use.

[0024] At the same time, the reinforcing plate 107 is fixedly connected to the fixing ring 104, and is located on the side of the fixing ring 104 away from the abutment plate 105, and is connected to the housing 100; the reinforcing rod 108 is fixedly connected to the reinforcing plate 107, and is located on the side of the reinforcing plate 107 away from the fixing ring 104, one side of the reinforcing plate 107 is mounted on the fixing ring 104 by bolts, and the other side of the reinforcing plate 107 is mounted on the housing 100 by bolts, and the reinforcing plate 107 is used to increase the reinforcing rod 108. The connection strength between the fixed ring 104 and the outer shell 100 is increased, so that the fixed ring 104 can support the equipment more stably. One end of the reinforcement rod 108 is installed on the side of the reinforcement plate 107 close to the fixed ring 104 by welding, and the other end of the reinforcement rod 108 is installed on the side of the reinforcement plate 107 close to the outer shell 100 by welding. The strength of the reinforcement plate 107 is increased by the reinforcement rod 108, so that the reinforcement plate 107 can support the fixed ring 104 more stably.

[0025] In addition, the fixed base 109 is fixedly connected to the fixed ring 104 and is located on a side of the fixed ring 104 away from the reinforcement plate 107; the hydraulic rod 110 is fixedly connected to the fixed base 109 and is located on a side of the fixed base 109 away from the fixed ring 104, and is connected to the abutment plate 105. The fixed base 109 is installed on a side of the fixed ring 104 away from the reinforcement plate 107 by bolts, and the hydraulic rod 110 is installed on a side of the fixed base 109 away from the fixed ring 104 by bolts. The hydraulic rod 110 is stably installed on the fixed ring 104 through the fixed base 109, and the abutment plate 105 is installed on the output end of the hydraulic rod 110 by bolts. The abutment plate 105 is driven to move by the hydraulic rod 110, so that the abutment plate 105 can abut against the ground, thereby lifting the equipment.

[0026] When the device needs to be moved by using the hydrogen generator for a gas chromatograph of the present embodiment, the hydraulic rod 110 is started to move the abutment plate 105 to the side close to the fixing ring 104, so that the device is lowered and the universal wheel 103 is in contact with the ground. The universal wheel 103 makes the device easier to move. When the device moves to a specified position, the hydraulic rod 110 is started to make the abutment plate 105 in contact with the ground, thereby raising the device and leaving the universal wheel 103 off the ground, thereby making it possible to move the device more conveniently. At the same time, the stability of the device during use is ensured, thereby improving the efficiency of the device.

[0027] The second embodiment of the present application is:

[0028] Based on the first embodiment, please refer to Figure 3 , Figure 3 It is a schematic diagram of the installation of the first shell and the second shell of the second embodiment of the utility model.

[0029] The moving assembly of this embodiment further includes a first housing 211 and a second housing 212 .

[0030] Among them, the first shell 211 is fixedly connected to the fixing ring 104 and is located on a side of the fixing ring 104 close to the fixing base 109; the second shell 212 is fixedly connected to the abutment plate 105 and is located on a side of the abutment plate 105 close to the hydraulic rod 110, and abuts against the first shell 211. The first shell 211 is installed on a side of the fixing ring 104 close to the fixing base 109 by bolts. The length of the first shell 211 is less than half the length of the hydraulic rod 110. The second shell 212 is installed on a side of the abutment plate 105 close to the fixing ring 104 by bolts, so that the second shell 212 moves up and down with the abutment plate 105, and the gap between the fixing ring 104 and the abutment plate 105 is blocked by the first shell 211 and the second shell 212, thereby preventing the abutment plate 105 from clamping foreign objects when moving.

[0031] Using a hydrogen generator for a gas chromatograph of this embodiment, the gap between the fixing ring 104 and the abutment plate 105 is shielded by the first shell 211 and the second shell 212, thereby preventing the abutment plate 105 from clamping foreign objects when moving, thereby ensuring the normal operation of the equipment.

[0032] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
