Description

Technical Field

[0001] This utility model relates to the technical field of gas cylinder transfer devices, and in particular to an auxiliary transfer device for helium gas cylinders. Background Technology

[0002] Helium is a rare gas and needs to be collected in special helium cylinders for transportation. If the helium cylinders are subjected to collisions, vibrations or other physical impacts during transportation, the cylinders may be damaged or leaked, increasing the risk of helium leakage. Therefore, transfer equipment is required to assist in the process.

[0003] Chinese Patent Authorization Announcement No.: CN221090912 U, Authorization Announcement Date: June 7, 2024. This utility model relates to a helium cylinder transfer device for transferring helium cylinders. It includes a support assembly, a base plate assembly, and a frame assembly. The base plate assembly is telescopically connected to the bottom of the support assembly. The support assembly includes a frame body, a first bracket, and a fixing hoop. The first bracket is located in the middle of the frame body. One end of the fixing hoop is hinged to the frame body, and the other end is detachably connected to the frame body. The frame assembly is connected to the first bracket via a second hydraulic cylinder and is hinged to the bottom of the frame body. The first bracket includes a guardrail, a support plate, a clamping plate, and a first spring. The guardrail and support plate are connected by the first spring, and the guardrail and clamping plate are connected by a telescopic cylinder. The support plate and clamping plate are hinged. The shortcomings of this technical solution are: 1. The vertical fixation of the cylinder body is weak, making it prone to detachment and collision during long-distance transport; 2. Exposed parts are susceptible to damage and leakage due to localized impacts.

[0004] In summary, existing transfer devices have shortcomings in providing poor protection for helium cylinders during transfer, making them prone to breakage and leakage. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing transfer devices, such as poor protection of helium cylinders during transfer, which can easily lead to damage and leakage. It provides an auxiliary transfer device for helium cylinders that improves transfer protection and prevents damage and leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An auxiliary transfer device for helium cylinders, comprising: The base is connected to a limiting groove, and the limiting groove is connected to a shock-absorbing pad. The housing sleeve has a positioning groove on the base, and the housing sleeve is engaged with the positioning groove. The limiting strip has one end elastically connected to the inner wall of the housing sleeve, and the other end is connected to a shock-absorbing pad. The limiting top plate is elastically connected to the top of the inner cavity of the housing sleeve, and the limiting top plate is connected with shock-absorbing pad three. The locking structure has one end connected to the base and the other end connected to the housing sleeve. The movable roller is movably connected to the housing sleeve, and the base is provided with a clearance groove that is adapted to the movable roller. The handle is rotatably connected to the sleeve of the box.

[0007] The base is connected to the first shock-absorbing pad via a limiting groove, allowing the helium cylinder to be placed on it. The lower height of the pad allows for quick placement of the cylinder, while the first shock-absorbing pad cushions the cylinder. The housing sleeve fits onto the base containing the cylinder and engages with the positioning groove, enabling the housing sleeve to quickly connect to the base and enclose the cylinder. Internal limiting strips provide shock absorption protection from the sides of the cylinder, and a top limiting plate provides shock absorption protection from the top. The second and third shock-absorbing pads provide shock absorption protection and, through elastic connection, further buffer impacts during transport and adapt to slight differences in cylinder dimensions, improving the device's flexibility. A locking structure locks the base and housing sleeve to prevent them from separating during transport. Moving rollers allow for high-speed and easy horizontal movement during transport. These rollers can extend into the base via clearance grooves and can be retracted for easy transport to a conveyor to prevent slippage. A handle connected to the housing sleeve assists in vertical movement during transport, providing a point of leverage and eliminating the need to lift the entire device. It achieves stable and efficient transfer assistance, makes the transfer process easy and labor-saving, and enhances the protection of helium cylinders during transfer to prevent damage and leakage.

[0008] Preferably, one side of the shock-absorbing pad is fitted into the limiting groove, and the other end of the shock-absorbing pad is provided with a placement groove. The opening of the placement groove and the surface of the shock-absorbing pad are chamfered. The shock-absorbing pad is fixed by being embedded in the limiting groove, preventing the groove's shape from being adapted to the bottom of the helium cylinder. At the same time, the chamfered opening of the placement groove and the surface of the shock-absorbing pad keeps the groove open, allowing the cylinder to be quickly and guideably placed into the placement groove. This improves the stability and efficiency of cylinder placement.

[0009] Preferably, the inner cavity of the sleeve is provided with a placement cavity. The cavity wall of the placement cavity has several mounting slots, each into which a connecting rod is inserted. The connecting rod is connected to a limiting strip, and a flexible mechanism is connected to the connecting rod. One end of the flexible mechanism is connected to the cavity wall of the placement cavity, and the other end is connected to the limiting strip. The inner wall of the placement cavity has several vertically arranged mounting slots to position and connect the connecting rod, providing support for the limiting strip and thus stabilizing the shock-absorbing pad. The flexible mechanism connects the placement cavity and the limiting strip, stabilizing the connection between the connecting rod and the limiting strip, and providing reverse support and buffering against external vibrations when the shock-absorbing pad is under stress. This improves the stability of the connection between the device structures and enhances the buffering performance, protecting the bottle.

[0010] Preferably, both the limiting strip and the second shock-absorbing pad have guide bevels on their end faces. The beveled end faces of the limiting strip and the second shock-absorbing pad facilitate contact and gradual interaction between the bottle and the second shock-absorbing pad when the casing sleeve is connected to the base. This improves the smoothness of the bottle transfer operation.

[0011] Preferably, the top of the placement cavity is provided with a second mounting slot, into which a second connecting rod is inserted. A second elastic mechanism is sleeved on the second connecting rod, with one end connected to the placement cavity and the other end connected to a limiting top plate. The top of the placement cavity is positioned and connected to the second connecting rod via the second mounting slot. The second elastic mechanism on the second connecting rod connects the limiting top plate to the placement cavity, ensuring that when the sleeve is pressed down, the third shock-absorbing pad abuts against the top of the bottle and buffers external impact vibrations. This achieves the effect of improving the connection stability and buffering performance between the device structures, protecting the bottle.

[0012] Preferably, the locking structure includes a locking rod and a latch. The base has a rotating groove, which connects to a rotating rod. One end of the locking rod has a rotating hole, into which the rod inserts. The other end of the rod connects to the latch. The outer side of the sleeve has a mating groove with a locking slot. The locking rod inserts into the mating groove, and the latch engages with the locking slot. The locking rod is rotatably connected to the rotating groove of the base via the rotating rod, allowing the rod to rotate and enter the mating groove. After the sleeve is released, the latch engages with the locking slot under elastic force, quickly and easily locking the sleeve to the base. This improves the stability of the device and the protection of the bottle.

[0013] Preferably, the movable roller is connected to a connecting shaft, the housing sleeve has a placement opening, the placement opening is connected to a shaft, the connecting shaft has an insertion hole, the shaft is inserted into the insertion hole, the connecting shaft is adapted to a clearance groove, and the base has a sliding groove, the sliding groove is slidably connected to a sliding rod, and the sliding groove communicates with the placement opening. The movable roller is connected to the shaft in the placement opening via the connecting shaft and can rotate through the insertion hole. The connecting shaft is removed from the placement opening and inserted into the clearance groove of the base, and locked by the sliding rod. The lowered movable roller can then quickly and stably move the device by rolling. This achieves the effect of improving the stability and efficiency of the device's transport.

[0014] Preferably, the outer side of the casing sleeve is connected to a handle base. Two handle bases are provided, each with a insertion hole. The two ends of the handle are inserted into these holes, and a cushioning sleeve is fitted onto the handle. A protective pad is placed between the handle bases, and this protective pad is connected to the casing sleeve. The outer side of the casing sleeve connects to the handle via the insertion holes in the handle bases, ensuring the handle's stability. Simultaneously, the cushioning sleeve on the handle and the protective pad between the handle bases provide a softer feel during transport and handling, preventing hand injuries when force is applied. This achieves the effect of improving transport efficiency and safety.

[0015] The beneficial effects of this utility model are: achieving stable and efficient transfer assistance; making the transfer process easy and labor-saving; enhancing the protection of helium cylinders during transfer to prevent breakage and leakage; improving the stability and efficiency of cylinder placement; and improving the stability and buffering performance of connections between device structures.
