Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas cylinder transfer technology, specifically a labor-saving transfer device for large-capacity laboratory gas cylinders. Background Technology
[0002] Large-capacity gas cylinders (typically 40L to 50L) are common storage devices in laboratories for providing high-purity gases to analytical instruments such as gas chromatographs and mass spectrometers. To safely hold gases at pressures up to 15 MPa or even higher, these cylinders are usually made of high-strength materials such as carbon steel, with thick walls, resulting in an empty cylinder weighing approximately 50 kg and a full cylinder weighing 60 kg or more. This significant weight makes manual handling extremely difficult, not only physically demanding but also posing safety risks such as tipping and impact.
[0003] Currently, trolleys and other transfer devices are commonly used in laboratories to move gas cylinders. While these devices solve the problem of horizontal movement of gas cylinders on flat surfaces, significant shortcomings remain in the loading and unloading process. Specifically, both lifting the gas cylinder from the ground onto the transfer device and unloading it from the transfer device require considerable physical strength from the operator. This is especially true for female laboratory staff with relatively less strength or those lacking physical strength, as this process can easily lead to loss of control of the gas cylinder due to insufficient strength, resulting in serious safety accidents such as crushing injuries, sprains, or gas leaks.
[0004] To address the problem of laborious loading and unloading, some existing technologies have developed transfer equipment using electrically driven lifting mechanisms. However, such equipment is expensive to manufacture and has a complex structure. In environments with limited space, such as laboratories, where there may be corrosive conditions or explosion-proof requirements, its applicability, reliability, and ease of maintenance are all insufficient. Utility Model Content
[0005] The purpose of this invention is to provide a labor-saving transfer device for large-capacity gas cylinders in laboratories, so as to solve the problems of laborious loading and unloading of gas cylinders, safety hazards, high cost and inconvenient maintenance of electric equipment in the existing technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a labor-saving transfer device for large-capacity laboratory gas cylinders, comprising:
[0007] The main frame is constructed from welded rectangular steel tubing.
[0008] The gas cylinder support and fixing mechanism includes three inclined baffles fixedly installed on the inner wall of the vehicle frame body. One of the inclined baffles is installed on the left inner wall, and the other two inclined baffles are arranged vertically on the right inner wall. The supporting inclined surfaces of all the inclined baffles are parallel to each other, forming an inclined supporting surface that is adapted to the cylindrical body of the gas cylinder, so as to keep the gas cylinder in a stable inclined posture within the vehicle frame body.
[0009] The fixing bar is installed through an L-shaped slot located at the front of the main body of the vehicle frame;
[0010] The armrest is fixedly installed on the main body of the vehicle frame and located below the L-shaped slot;
[0011] Multiple casters are installed at the bottom of the main frame.
[0012] Preferably, the single inclined baffle on the left and the two inclined baffles arranged vertically on the right are staggered in the vertical direction to form a stable three-point support system.
[0013] Preferably, the angle between the supporting inclined surface of the inclined baffle and the horizontal plane is 15° to 25°.
[0014] Preferably, the handrail has an internal rectangular steel pipe welded frame and is fully covered with a TPE layer on the outside.
[0015] Preferably, at least two of the casters are equipped with a foot-operated locking mechanism.
[0016] Preferably, after the fixing bar is inserted into the L-shaped slot, it forms a closed rectangular frame together with the bottom of the frame body to ensure the overall structural stability.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. This utility model allows the gas cylinder to be slowly pushed into the main body of the frame. The cylinder body contacts three inclined baffles. The single inclined baffle on the left inner wall and the two inclined baffles arranged vertically on the right inner wall together form an inclined support surface. The user only needs to apply slight force to make the gas cylinder slide in along the support slope, naturally maintaining an inclined posture. Since the support slopes of the inclined baffles are parallel to each other and have an angle of 15° to 25° with the horizontal plane, the gas cylinder will automatically balance without additional support. The three-point support system formed by the inclined baffles realizes the stable inclined placement of the gas cylinder, effectively reducing the force required for loading. The user does not need to fully lift the gas cylinder, but only needs to push it to complete the loading, greatly reducing physical exertion, and is especially suitable for laboratory staff with less strength.
[0019] 2. When the fixing bar is fully inserted into the L-shaped slot, it forms a closed rectangular frame together with the bottom of the frame body. The closed rectangular frame structure enhances the overall structural rigidity and stability of the front of the device. It can effectively resist the torque and deformation generated during transportation and ensure that the fixing bar will not come out accidentally. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] like Figure 1 As shown:
[0026] Example 1: This utility model provides a labor-saving transfer device for large-capacity gas cylinders in the laboratory, comprising:
[0027] The main frame 1 is constructed from welded rectangular steel tubing.
[0028] The gas cylinder support and fixing mechanism includes three inclined baffles 2 fixedly installed on the inner wall of the frame body 1. One inclined baffle 2 is installed on the left inner wall, and the other two inclined baffles 2 are arranged vertically on the right inner wall. The supporting inclined surfaces of all the inclined baffles 2 are parallel to each other, forming an inclined supporting surface that is adapted to the cylindrical body of the gas cylinder, so as to keep the gas cylinder in a stable inclined posture within the frame body 1.
[0029] The fixing bar is installed through the L-shaped slot 3 located at the front of the frame body 1;
[0030] The handrail is fixedly installed on the main body 1 of the frame and located below the L-shaped slot 3;
[0031] Multiple omnidirectional wheels 4 are installed at the bottom of the main frame 1.
[0032] First, push the gas cylinder into the frame body 1. The cylinder body contacts the three inclined baffles 2, and the cylinder slides in along the inclined surface. It is supported by a single inclined baffle 2 on the left and two inclined baffles 2 arranged vertically on the right. These three support points are staggered in the vertical direction, forming a stable three-point support system. This design ensures that the weight of the gas cylinder is evenly distributed on the three contact points. At the same time, the center of gravity of the gas cylinder is reliably constrained within this triangular support area, using gravity to naturally stabilize it in an inclined posture without any additional force to maintain balance. After the gas cylinder is in place, the user installs the fixing bar through the L-shaped slot 3 set at the front of the frame body 1 to increase the stability of the device. Hold the handle and push the device. The multiple universal wheels 4 at the bottom of the device start to roll, realizing easy steering and movement.
[0033] 1. In one embodiment of the present invention, the single inclined baffle 2 on the left and the two inclined baffles 2 arranged vertically on the right are staggered in the vertical direction to form a stable three-point support system.
[0034] The gas cylinder is supported by a single inclined baffle 2 on the left and two inclined baffles 2 arranged vertically on the right. These three support points are staggered in the vertical direction, forming a stable three-point support system. This system effectively distributes the weight of the gas cylinder to three non-collinear support points, minimizing the risk of the gas cylinder rolling or shaking within the device and ensuring the reliability of the static support.
[0035] 2. In one embodiment of the present invention, the angle between the supporting inclined surface of the inclined baffle 2 and the horizontal plane is 15° to 25°.
[0036] The angle range has been optimized to ensure that the center of gravity of the gas cylinder is low enough to maintain stability when tilted, while also preventing the tilt angle from being too large. This allows users to complete loading and unloading with only a small component of gravity, achieving the best balance between effort saving and stability.
[0037] 3. In one embodiment of this utility model, the inside of the handrail is a rectangular steel pipe welded frame, and the outside is fully covered with a TPE layer.
[0038] The internal rectangular steel tube frame ensures the structural strength and durability of the handrail, while the external full-coverage TPE layer provides a soft, comfortable, and non-slip grip surface, improving the user experience and effectively absorbing shock when pushed.
[0039] 4. In one embodiment of this utility model, at least two of the casters 4 are equipped with foot-operated locking mechanisms.
[0040] When temporary parking is required, users can step on the foot-operated locking mechanism on at least two of the casters 4. The foot-operated locking mechanism can quickly and easily lock the device in place, preventing it from moving accidentally on slopes or uneven ground, thus enhancing operational safety.
[0041] Example 2: This example is basically the same as the previous example, except that after the fixing bar is installed into the L-shaped slot 3, it forms a closed rectangular frame together with the bottom of the frame body 1 to ensure the overall structural stability.
[0042] When the fixing bar is fully inserted into the L-shaped slot 3, it forms a closed rectangular frame together with the bottom of the frame body 1. The closed rectangular frame structure enhances the overall structural rigidity and stability of the front of the device. It can effectively resist the torque and deformation generated during transportation and ensure that the fixing bar will not come out accidentally.
[0043] Application Process: The user slowly pushes the gas cylinder into the frame body 1. The cylinder body contacts the three inclined baffles 2. The single inclined baffle 2 on the left inner wall and the two inclined baffles 2 arranged vertically on the right inner wall together form an inclined support surface. The user only needs to apply slight force to let the gas cylinder slide in along the support slope, naturally maintaining its inclined posture. Since the support slopes of the inclined baffles 2 are parallel to each other and have an angle of 15° to 25° with the horizontal plane, the gas cylinder will automatically balance without additional support. The three-point support system formed by the inclined baffles 2 achieves stable inclined placement of the gas cylinder, effectively reducing the force required for loading. The user does not need to fully lift the gas cylinder, but only needs to push it to complete the loading, greatly reducing physical exertion, especially suitable for laboratory staff with less strength. After the gas cylinder is placed stably, the user inserts the fixing bar into the L-shaped slot 3 at the front of the frame body 1. The fixing bar is fully inserted. Afterwards, together with the bottom of the frame body 1, a closed rectangular frame is formed. The closed rectangular frame structure enhances the overall stability. The user holds the handle and slowly pushes the device. The handle has a rectangular steel pipe welded skeleton inside and is fully covered with a TPE layer on the outside, providing a comfortable grip and anti-slip effect. During movement, the user can flexibly turn through the bottom universal wheels 4 to adapt to the narrow space of the laboratory or corridor environment. If temporary parking is required, the foot-operated locking mechanism on at least two universal wheels 4 can be stepped on to prevent the device from sliding. After reaching the destination, the fixing bar is removed from the L-shaped slot 3. Then, the gas cylinder is gently pulled to make it slowly slide out along the supporting slope of the inclined baffle 2. Since the three-point support system keeps the gas cylinder balanced, the unloading process can be completed with minimal force. The whole operation does not require electricity or external power, reducing the failure rate and maintenance costs, and is suitable for long-term use in the laboratory environment.
[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
