Description

Technical Field

[0001] This utility model relates to the field of helium filling technology, specifically a helium filling device. Background Technology

[0002] Helium, a rare gas, possesses characteristics such as low density, low boiling point, and chemical stability, playing a vital role in numerous fields. It is widely used in medicine (e.g., MRI machine cooling), scientific research (e.g., cryogenic experiments), aerospace (e.g., pressure regulation in rocket propulsion systems), electronics manufacturing (e.g., environmental control in semiconductor production processes), and the entertainment industry (e.g., balloon filling). With the development of these industries, the demand for efficient and safe helium filling solutions is increasing daily.

[0003] The patent with publication number CN215597045U discloses an easy-to-operate high-purity helium filling device, including a device body. A filling rack is vertically mounted on one end of the top of the device body. A fixing plate is provided on the top of the device body. A fixing back plate is vertically provided on the top of the fixing plate. An elastic fixing band is provided on the outer surface of the fixing back plate. A handle is provided on the outer surface of the elastic fixing band. A clearance hole is provided through the surface of the handle. A fixing frame is provided on the surface of the fixing back plate. An internal thread is provided through the surface of the fixing frame. An adjusting rod is provided through the surface of the fixing frame. An external thread is provided at the middle position of the surface of the adjusting rod. The adjusting rod is helically connected to the internal thread. An adjusting wheel is provided at one end of the adjusting rod.

[0004] However, the above-mentioned device has the following problems when in use: When using the device for helium filling, after each helium cylinder to be filled is moved to the designated position, the operator needs to manually perform a series of steps, including reloading, setting limits, and completing the unloading activity. These steps result in low efficiency of the whole process. In addition, the device is designed to only support the filling operation of a single helium cylinder at a time, which means that the above operation process must be repeated for each helium cylinder in turn, and multiple helium cylinders cannot be processed at the same time, which greatly limits the overall work efficiency and production capacity. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a helium filling device that simplifies the operation steps and ensures the continuity of filling and transfer activities.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A helium filling device includes a fixed frame and a placement plate. The placement plate is equipped with a push plate and casters. The placement plate has placement grooves at equal intervals. The placement plate is provided with a limiting mechanism. Side blocks are fixedly installed on both sides of the placement plate. The fixed frame has limiting grooves at corresponding positions that are adapted to the side blocks. An installation frame is fixedly installed on the fixed frame. A connecting mechanism is slidably installed on the installation frame.

[0008] Preferably, the limiting mechanism includes a drive motor, which is mounted on the placement plate. A bidirectional threaded rod is fixedly installed on the output end of the drive motor shaft. Two nut pairs are threadedly installed on the bidirectional threaded rod. A mounting plate is fixedly installed on each of the two nut pairs. The two mounting plates are arranged opposite to each other. Limiting arc plates are fixedly installed at equal intervals on the upper and lower sides of the two mounting plates. The limiting arc plates at corresponding positions on the same mounting plate are connected by connecting columns.

[0009] Preferably, the limiting arc plate is semi-circular, and the limiting arc plate can form an annular cross section with the corresponding limiting arc plate on another mounting plate, which has the same inner diameter radius as the radius of the bidirectional threaded rod.

[0010] Preferably, the connecting mechanism includes a movable plate, which is slidably mounted on the mounting frame. Gas delivery hoses are equidistantly embedded in the movable plate, and a connector is installed at the end of the gas delivery hose opposite to the movable plate. The mounting frame has a groove for the movable plate to slide.

[0011] Preferably, the gas delivery hose is positioned between adjacent helium cylinders.

[0012] Preferably, two magnetic blocks are embedded in the mounting frame, and a magnet is embedded in the side of the moving plate facing the magnetic blocks at the position corresponding to the magnetic blocks. The magnetic blocks can be magnetically attracted and engaged with the magnet. A moving handle is fixedly installed on the moving plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) First, the placement grooves equidistantly opened on the placement plate allow multiple helium cylinders to be processed at the same time without additional loading and unloading operations, simplifying the operation process. Second, the side block and the limiting groove on the fixed frame are precisely matched to ensure that the placement plate can be positioned quickly and accurately, reducing adjustment time. In addition, after filling is completed, the entire placement plate can be transferred directly together with the filled helium cylinders without the need to remove each cylinder separately, further improving the operation efficiency. It not only simplifies the operation steps, but also realizes an integrated solution for filling and transfer, greatly improving the processing speed and work efficiency.

[0015] (2) This utility model ensures that the gas delivery hose and its connector are firmly held at the edge when not in use by the magnetic adsorption function between the magnetic block and the magnet. The gas delivery hose and connector will not interfere with the movement path of the helium cylinder, avoiding unnecessary contact or collision, and protecting the connector and its sensor from damage. In addition, the gas delivery hose is cleverly placed between adjacent helium cylinders, which also ensures that the connector can be smoothly connected without obstruction during the filling operation, greatly reducing the risk of collision, ensuring the safety and stability of the equipment, and extending the service life of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4 A helium filling device includes a fixed frame 1 and a placement plate 2. The fixed frame 1 provides support for the overall structure, while the placement plate 2 is used to place the helium cylinder to be filled and to quickly transfer the filled helium cylinder.

[0023] The placement plate 2 is equipped with a push plate 3 and casters 4. The push plate 3 is used to assist in the operation of the placement plate 2, while the casters 4 make it easy for the operator to move the entire placement plate 2 and facilitate transfer activities.

[0024] The placement plate 2 has equidistant placement grooves 13 and a limiting mechanism. One placement groove 13 corresponds to the position of one helium cylinder, ensuring that the cylinder is placed stably and allowing multiple cylinders to be processed at the same time. The limiting mechanism is used to stabilize the helium cylinder during filling and transfer, preventing it from shifting or tipping due to pressure changes or other external forces.

[0025] Side blocks 12 are fixedly installed on both sides of the placement plate 2. The fixing frame 1 has a limiting groove 21 that matches the side block 12 at the corresponding position. This design ensures that the placement plate 2 can be accurately aligned and smoothly slide into the fixing frame 1, achieving quick and accurate positioning and facilitating subsequent pipe connection activities.

[0026] A mounting bracket 5 is fixedly installed on the fixed frame 1, and a connecting mechanism is slidably installed on the mounting bracket 5.

[0027] The limiting mechanism includes a drive motor 14, which is mounted on the placement plate 2. A bidirectional threaded rod 15 is fixedly mounted on the output end of the shaft of the drive motor 14. Two nut pairs 16 are threadedly mounted on the bidirectional threaded rod 15. Mounting plates 17 are fixedly mounted on both nut pairs 16. The two mounting plates 17 are arranged opposite to each other. Limiting arc plates 18 are fixedly mounted at equal intervals on the upper and lower sides of the two mounting plates 17. The limiting arc plates 18 at corresponding positions on the same mounting plate 17 are connected by connecting posts 19.

[0028] When the drive motor 14 is started, the bidirectional threaded rod 15 fixed at the output end of its shaft rotates, driving two nut pairs 16 to move towards each other along the bidirectional threaded rod 15. Each nut pair 16 is connected to a mounting plate 17. Limiting arc plates 18 are fixed on the upper and lower sides of the mounting plate 17. As the drive motor 14 rotates, the two mounting plates 17 move towards each other or away from each other, and the helium cylinder is securely clamped by the cooperation of the corresponding limiting arc plates 18.

[0029] The limiting arc plate 18 is semi-circular. The limiting arc plate 18 can form an annular cross section with the inner diameter radius of the bidirectional threaded rod 15 together with the corresponding limiting arc plate 18 on another mounting plate 17.

[0030] The connecting mechanism includes a movable plate 6, which is slidably mounted on the mounting frame 5. Gas delivery hoses 7 are equidistantly embedded on the movable plate 6. A connector 8 is installed at the end of the gas delivery hose 7 facing away from the movable plate 6. The mounting frame 5 has a sliding groove 9 for the movable plate 6 to slide.

[0031] By keeping the moving plate 6 stably positioned at the edge, the gas delivery hose 7 and connector 8 will not obstruct the movement path of the helium cylinder during its movement, and the helium cylinder will not collide with the connector 8, thereby effectively ensuring the service life of the connector 8 and its corresponding sensor.

[0032] The gas delivery hose 7 is located between adjacent helium cylinders.

[0033] When the placement plate 2 is moved to the position, the moving plate 6 is moved so that the gas delivery hose 7 and the connector 8 will not collide with the helium cylinder. At this time, it is only necessary to connect the connector 8 to the corresponding position of the helium cylinder.

[0034] Two magnetic blocks 10 are embedded in the mounting bracket 5. A magnet 20 is embedded in the side of the moving plate 6 facing the magnetic block 10 at the position corresponding to the magnetic block 10. The magnetic block 10 can be magnetically attracted and engaged with the magnet 20. A moving handle 11 is fixedly installed on the moving plate 6.

[0035] The magnetic attraction function of the magnetic block 10 and the magnet 20 helps the moving plate 6 to be stably in the corresponding position, thereby ensuring that the gas hose 7 and the connector 8 will not move accidentally. The moving plate 6 can only be pushed by the moving handle 11, thereby completing the position adjustment of the gas hose 7 and the connector 8.

[0036] The working process of this utility model is as follows: Workers place the helium cylinders to be filled into the placement grooves 13 of the placement plate 2 at the location where helium cylinders are stacked. Because the placement grooves 13 are equidistantly spaced, the position of each helium cylinder is ensured to be accurate and stable. The drive motor 14 is started, and the bidirectional threaded rod 15 at its shaft output end begins to rotate, driving two nut pairs 16 to move towards each other along the bidirectional threaded rod 15. Since each nut pair 16 is connected to a mounting plate 17, and the mounting plate 17 has limiting arc plates 18 fixed on its upper and lower sides, as the drive motor 14 rotates, the two mounting plates 17 move towards each other. Through the cooperation of the corresponding limiting arc plates 18, the helium cylinder is securely clamped, preventing displacement or tipping during filling and transfer due to pressure changes or other external forces.

[0037] Then, by moving the placement plate 2, multiple helium cylinders to be filled are moved synchronously to their corresponding positions. Subsequently, by cooperating with the limiting groove 21 on the fixing frame 1 through the side block 12, the placement plate 2 is precisely aligned and smoothly slides into the fixing frame 1, preparing for subsequent pipeline connection.

[0038] During the process of placing plate 2 entering and moving out, by keeping moving plate 6 stably at the edge, the gas delivery hose 7 and connector 8 will not obstruct the movement path of helium cylinder during the movement of helium cylinder, and helium cylinder will not collide with connector 8, thereby effectively ensuring the service life of connector 8 and the corresponding sensor on it.

[0039] When the placement plate 2 is in place, the moving plate 6 is pulled by the moving handle 11, allowing it to slide within the groove 9 of the mounting bracket 5. At this time, the gas delivery hose 7 and the connector 8 move with the moving plate 6. Simply align the connector 8 with the corresponding position on the helium cylinder to begin filling. After alignment, push the moving handle 11 to move the moving plate 6. The magnetic block 10 and the magnet 20 magnetically attract each other, helping to stabilize the moving plate 6 at the edge position and ensuring that the gas delivery hose 7 and connector 8 do not move accidentally.

[0040] After filling is completed, the clamping activity continues. The operator can easily move the entire placement plate 2 using the push plate 3 and the casters 4 to quickly transfer the filled helium cylinder to the designated location.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
