Technical Field

[0001] The utility model relates to the technical field of gas cylinder cabinets, in particular to a safety gas cylinder cabinet for laboratories. Background Art

[0002] Since gas cylinders are dangerous, they need to be placed in a special environment to ensure safety. Gas cylinder cabinets can keep the air flowing and protect items such as cylinders from being affected by the external environment. Gas cylinder cabinets generally include ordinary single-bottle gas cylinder cabinets, double-bottle automatic alarm gas cylinder cabinets, or exhaust-type gas cylinder cabinets, etc., which are used to meet various needs of laboratories. However, gas cylinders, as a pressure-bearing equipment, are explosive hazards, and the media they contain are generally flammable, explosive, toxic, and highly corrosive. Conventional gas cylinder storage cabinets usually place gas cylinders directly in the cabinet without additional gas cylinder position fixing equipment. Gas cylinders are extremely susceptible to impacts such as bumps. Unfixed gas cylinders will move and collide significantly in the cabinet, and there is a risk of gas cylinder rupture and explosion.

[0003] Patent application number "CN202121243652.X" describes "a laboratory gas cylinder storage cabinet with high safety performance, including a storage box, which enables staff to quickly open or close the clamps, thereby facilitating the storage or retrieval of the gas cylinder body. This method has a simple structure, convenient operation, high practicality, and at the same time good safety and reliability."

[0004] However, since the gas cylinder itself is heavy, the device may cause the gas cylinder to tilt during the process of taking out the gas cylinder due to its own weight and lack of support at the bottom, which may cause the gas cylinder cabinet to collapse and cause a safety accident.

[0005] Therefore, the utility model provides a laboratory safety gas cylinder cabinet to solve the above problems. Utility Model Content

Beneficial Effects

[0014] The utility model provides a laboratory safety gas cylinder cabinet. Compared with the prior art, it has the following beneficial effects:

[0015] (1) The laboratory safety gas cylinder cabinet uses an electric push rod to push the moving plate out of the cabinet body, driving the gas cylinder above the moving plate to move outward. At the same time, the gas cylinder will press the sliding plate to slowly move downward inside the sliding straight groove under the action of the damping component, and the support wheel at the bottom of the moving plate will pop out under the action of the torsion spring, thereby supporting the gas cylinder to slowly move outward on the moving plate through the support wheel, thereby avoiding the gas cylinder from tilting due to its own excessive weight and lack of support at the bottom, which may cause the gas cylinder cabinet to collapse and cause a safety accident.

[0016] (2) The laboratory safety gas cylinder cabinet can move the gas cylinder to the ground through the rollers and the rollers on the limit bracket, so that the gas cylinder can be moved to the appropriate position by rolling it. The air pressure instrument on the top of the cabinet can detect whether the gas cylinder is leaking by detecting the air pressure inside the cabinet when the cabinet door is closed, thereby avoiding safety hazards caused by gas cylinder leakage.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] See also Figures 1 to 4A laboratory safety gas cylinder cabinet includes a cabinet body 1 and a gas cylinder 5. A movable plate 6 is movably connected inside the cabinet body 1, and sliders 9 are fixedly connected to both ends of the movable plate 6. The movable plate 6 is rotatably connected to a limited bracket 12 through a rotating shaft 11. The bottom of the movable plate 6 is rotatably connected to a support wheel 8. A movable straight groove 17 matching the slider 9 is opened inside the cabinet body 1. An electric push rod 10 is fixedly connected inside the cabinet body 1, and one side of the movable plate 6 is fixedly connected to the output shaft of the electric push rod 10. A sliding plate 14 is movably connected inside the cabinet body 1, and the cabinet body 1 A sliding straight groove 16 matching the sliding plate 14 is provided inside, a damping assembly is fixedly connected between the sliding plate 14 and the sliding straight groove 16, a fixed bracket 15 is rotatably connected to the sliding plate 14, and the inner diameter of the fixed bracket 15 matches the top of the gas cylinder 5, a controller is fixedly connected to the handle 4, and the controller is connected to the electric push rod 10 by signal, a torsion spring is provided at the connection between the moving plate 6 and the support wheel 8 to facilitate the automatic ejection of the support wheel 8, and a ratchet that limits the support wheel 8 to rotate only in the clockwise direction is fixedly connected to the moving plate 6, and the controller on the handle 4 is used to control the rotation of the support wheel 8. The electric push rod 10 inside the cabinet 1 is started, so that the electric push rod 10 can push the moving plate 6 out of the cabinet 1 through the cooperation of the slider 9 and the moving straight groove 17. At the same time, when the moving plate 6 extends out of the cabinet 1, the moving plate 6 drives the gas cylinder 5 above the moving plate 6 to move outward. At the same time, since the top of the gas cylinder 5 is stuck on the fixed bracket 15, when the moving plate 6 brings the gas cylinder 5 out of the cabinet 1, the gas cylinder 5 will press the fixed bracket 15. Since there is a limit plate between the fixed bracket 15 and the sliding plate 14, the gas cylinder 5 will press the sliding plate 14 to damp the gas cylinder 5. Under the action of the component, it slowly moves downward inside the sliding straight groove 16. Since the limit bracket 12 is rotatably connected to the movable plate 6, the electric push rod 10 pushes the movable plate 6 to move outward, thereby knocking down the gas cylinder 5. At the same time, under the action of the torsion spring, the support wheel 8 at the bottom of the movable plate 6 pops out, thereby supporting the gas cylinder 5 to move slowly outward on the movable plate 6 through the support wheel 8, thereby avoiding the gas cylinder 5 from tilting due to its own excessive weight and lack of support at the bottom, which may cause the gas cylinder cabinet to collapse and cause a safety accident. Example

[0024] See also Figures 1 to 4 This embodiment provides a technical solution based on the first embodiment:

[0025] The outer side of the cabinet body 1 is rotatably connected with a cabinet door 2 through a hinge 3, and a handle 4 is fixedly connected to the cabinet door 2. One end of the movable plate 6 is movably connected with a roller 7 for facilitating the sliding of the gas cylinder 5. The bottom of the connection between the sliding plate 14 and the fixed bracket 15 is fixedly connected with a limit plate for limiting the downward rotation of the fixed bracket 15. The inner part of the limit bracket 12 is movably connected with a roller 13 for facilitating the sliding of the gas cylinder 5, and the roller 13 is fixedly connected with an anti-skid pad. Both ends of the slider 9 are fixedly connected with rollers for facilitating the movement of the slider 9 in the movable straight groove 17. The top of the cabinet body 1 is fixedly connected with a roller 13 for facilitating the sliding of the gas cylinder 5. An air pressure meter 18 is provided for detecting the air pressure inside the cabinet 1, and the air pressure meter 18 is connected to the interior of the cabinet 1. After the gas cylinder 5 is laid down, the gas cylinder 5 is pulled outward from the bottom, and the roller 13 on the roller 7 and the limiting bracket 12 enables the gas cylinder 5 to be moved to the ground, so that the gas cylinder 5 can be moved to a suitable position by rolling the gas cylinder 5 later. Through the air pressure meter 18 at the top of the cabinet 1, when the cabinet door 2 is closed, the air pressure inside the cabinet 1 can be detected to detect whether the gas cylinder 5 is leaking, so as to avoid safety hazards caused by leakage of the gas cylinder 5.

[0026] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] Working principle: when working, first open the handle 4, and start the electric push rod 10 inside the cabinet 1 through the controller on the handle 4, so that the electric push rod 10 can push the moving plate 6 out of the cabinet 1 through the cooperation of the slider 9 and the moving straight groove 17. At the same time, when the moving plate 6 extends out of the cabinet 1, the moving plate 6 drives the gas cylinder 5 above the moving plate 6 to move outward. At the same time, since the top of the gas cylinder 5 is stuck on the fixed bracket 15, in the process of the moving plate 6 bringing the gas cylinder 5 out of the cabinet 1, the gas cylinder 5 will press the fixed bracket 15. Since there is a limiting plate between the fixed bracket 15 and the sliding plate 14, the gas cylinder 5 will press the sliding plate 14 under the action of the damping component, and slowly move downward inside the sliding straight groove 16. Since the limiting bracket 12 is rotatably connected to the moving plate 6, the electric push rod 10 pushes the moving plate 6 to move outward. The support wheels 8 at the bottom of the movable plate 6 are ejected by the torsion spring, thereby supporting the gas cylinder 5 to slowly move outward on the movable plate 6 through the support wheels 8, thereby preventing the gas cylinder 5 from tilting due to its own excessive weight and lack of support at the bottom, which may cause the gas cylinder cabinet to collapse and cause a safety accident. At the same time, after the gas cylinder 5 is laid down, the gas cylinder 5 is pulled outward from the bottom, and under the action of the rollers 7 and the rollers 13 on the limiting bracket 12, the gas cylinder 5 can be moved to the ground, so that the gas cylinder 5 can be moved to a suitable position by rolling it later. Through the air pressure instrument 18 at the top of the cabinet 1, when the cabinet door 2 is closed, it can be detected by detecting the air pressure inside the cabinet 1 to detect whether the gas cylinder 5 is leaking, thereby avoiding safety hazards caused by leakage of the gas cylinder 5.
