[0003] Therefore, this application provides an automatic high-purity helium filling device to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide an automatic high-purity helium filling device, which aims to solve the problem that existing filling devices use a threaded connection when connecting the female and male heads, which requires a long operation time when connecting and disconnecting.

[0005] To achieve the above objectives, this application provides the following technical solution: an automatic high-purity helium filling device, including a frame, a hanging rod, and a limiting rod. The top of the frame is provided with a hanging rod, and a gas pipe is provided on the frame. Multiple sets of pipes are provided on the gas pipe, and the pipes are hung on the hanging rod. A limiting rod for limiting the gas cylinder is provided on the frame. The gas cylinder is provided with a male connector that connects the inside and outside, and a female connector is provided at the free end of the pipe. The male and female connectors are compatible with each other.

[0006] The male head has an annular groove on its outer wall, and the female head has ball holes that connect the inside and outside. The ball holes are arranged in a circular array, and a limiting ball is provided in the ball hole. The limiting ball is adapted to the annular groove. A rotating component is rotatably connected to the outer wall of the female head. The inner wall of the rotating component has an unlocking groove with a triangular cross section. The unlocking groove is adapted to the limiting ball.

[0007] Preferably, a set of mounting parts is threaded onto the outer wall of the female head, the inner wall of the mounting parts is provided with an inner convex ring, and a gap is left between the inner convex ring and the outer wall of the female head;

[0008] The outer wall of the rotating component is provided with an outer convex ring, which is adapted to the inner convex ring, and the rotating component is slidably connected to the mounting component.

[0009] Preferably, a locking slot is provided between two sets of adjacent unlocking slots.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This invention utilizes a rotating component on the female connector. When aligning the female connector with the male connector, simply rotating it by a certain angle separates the locking groove from the limiting ball. Then, aligning the unlocking groove with the Z-axis of the ball hole releases the limiting ball. After inserting the male and female connectors, rotating the rotating component again allows the locking groove to engage with the limiting ball, thus achieving the insertion between the male and female connectors. Compared to existing technologies, this design allows for faster insertion and effectively improves production efficiency.

[0014] This invention utilizes the cooperation of a spring and a connecting chain to retract the connecting chain into a stretching groove when not in use, thus reducing space occupation. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Reference Figure 1-5 The high-purity helium automatic filling device shown includes a frame 1, a scraper, and a gas pipe 3. The frame 1 is installed against a wall and has an L-shaped cross-section. A hanging rod 2 is provided on the top outer wall of the frame 1. The hanging rod 2 is an arc-shaped rod, which facilitates the hanging and retrieval of the pipe. A gas pipe 3 is provided on the horizontal section of the frame 1. The gas pipe 3 is interconnected with the pipeline. The gas pipe 3 is supplied with gas by a gas supply component set up to the side. A male connector 9 for gas inlet is provided on the gas cylinder 8, and a female connector 10 that mates with the male connector 9 is provided at the free end of the pipeline.

[0024] As one embodiment of this invention, to improve the efficiency of docking the male connector 9 and the female connector 10, an annular groove 900 is provided on the outer wall of the male connector 9; a ball hole 1000 is provided on the outer wall of the female connector 10, and multiple sets of ball holes 1000 are arranged in a circular array, with a limiting ball provided inside the ball hole 1000; a set of mounting members 11 are threadedly connected to the outer wall of the female connector 10, and an inner convex ring 1100 is provided on the inner wall of the mounting member 11; a set of rotating members 12 are slidably connected to the mounting member 11, and an outer convex ring 1200 is provided on the outer wall of the rotating member 12 to limit the rotation member 12 (e.g., ...). Figure 4 As shown), to prevent the outer convex ring 1200 from sliding back and forth, a limiting spring or the like can be provided between the outer convex ring 1200 and the female head 10; an unlocking groove 1201 is provided on the inner wall of the rotating part 12, and the cross section of the unlocking groove 1201 is triangular; when the female head 10 and the male head 9 are connected, the ball hole 1000 and the unlocking groove 1201 are aligned vertically so that the limiting ball can slide and be assembled.

[0025] By using a set of locking grooves 1202 provided between two sets of adjacent unlocking grooves 1201, when it is necessary to push the limiting ball back into the ball hole 1000, the rotating part 12 is rotated so that the locking groove 1202 is opposite to the limiting ball, thereby pressing down the limiting ball to lock the female head 10 and the male head 9. Compared with the existing docking method, it is convenient, quick, time-saving, labor-saving and improves efficiency.

[0026] As one embodiment of this invention, a limiting rod 4 is provided on the outer wall of the frame 1, and a tension groove 400 is provided on the outer end face of the limiting rod 4. A set of connecting chains 6 is provided in the tension groove 400. The design of the tension groove 400 saves the space occupied by the connecting chains 6 when not in use. Furthermore, in order to improve portability, a pull ring is provided at the free end of the connecting chain 6, and a hanging post 7 is provided on the top surface of each set of limiting rods 4 so that when the connecting chain 6 is pulled out, the pull ring rests on the hanging post 7.

[0027] As one implementation method in this embodiment, in order to facilitate the repositioning of the pulled-out connecting chain 6, a spring 5 is connected between the connecting chain 6 and the stretch groove 400. The spring 5 is a tension spring, which automatically retracts into the stretch groove 400 after contacting the limit position of the pull ring and the hanging post 7.

[0028] The working principle of this utility model is as follows: The gas cylinder 8 is moved between the two sets of limiting rods 4, and then the pull ring is pulled to pull the connecting chain 6 outward. The pull ring is then placed on the hanging column 7 to limit the gas cylinder 8. Then the pipe is pulled to slide on the hanging rod 2. Then, the female head 10 is held and the rotating part 12 on the female head 10 is rotated to align the unlocking groove 1201 with the ball hole 1000, thereby releasing the limitation on the limiting ball. Then, the female head 10 is connected with the male head 9 on the gas cylinder 8, and the rotating part 12 is rotated again. The locking groove 1202 of the rotating part 12 presses down on the limiting ball again, so that the limiting ball is locked into the ring groove 900, completing the assembly. Then, the gas is delivered to the gas cylinder 8 through the gas pipe 3 and the pipeline via the gas supply component.

[0029] When maintenance is required on the rotating part 12, rotate the mounting part 11, unscrew the mounting part 11 from the female head 10, and then push the rotating part 12 backward to separate the rotating part 12 from the mounting part 11 for maintenance and replacement. The outer protruding ring 1200 on the rotating part 12 cooperates with the inner protruding ring 1100 on the mounting part 11 to limit the position during assembly.

[0030] After the pull ring is removed from the hanging post 7, the connecting chain 6 is pulled back by the spring 5 in the stretch groove 400 to achieve storage.
