Although the method of simply using the plug to pressurize the valve to make it fit with the pipe is simple and efficient, when in use, simply relying on the abutment of the plug may cause the valve port and the pipe to separate due to movement. Therefore, the valve needs to be positioned to avoid leakage caused by displacement during filling. Utility Model Content

DETAILED DESCRIPTION

[0026] The specific implementation methods of the utility model are further described in detail below in combination with the accompanying drawings. However, the following embodiments only list preferred embodiments, which only serve to explain and help understand the utility model and cannot be understood as limiting the utility model.

[0027] refer to Figure 2-7 A quick positioning cylinder filling clamp device comprises: an outer frame 1, a space for accommodating a valve 100 is arranged in the center of the outer frame, a pipe connecting unit 2 and a rotating fixing unit 3 are symmetrically arranged on the outer frame 1, the rotating fixing unit 3 comprises a screw rod 31 with a thread pattern, a pressure plate 32 is arranged at the front section of the screw rod, and a rotating handle 33 is arranged at the end; the front end of the pressure plate comprises a horizontal portion 321 arranged in the middle and protruding portions 322 arranged on both sides of the horizontal portion 321, and the width of the horizontal portion is not less than the width of the valve.

[0028] Reference when using Figure 2-4 By setting symmetrical pipe connection units and rotating fixing units on the outer frame, and by putting the outer frame on the valve to be connected, it can not only be positioned but also prevented from falling off. At the same time, the rotating fixing unit is used to rotate the screw rod to make the pressure plate press against the valve. Figure 5-6 , so that it is close to the pipe connection unit to complete the quick connection. Figure 2 A plurality of raised anti-slip portions 331 are provided on the wheel-shaped handle of the rotating handle, which can prevent the rotating handle from sliding when rotating.

[0029] As a preferred embodiment, a crank 34 is also provided on the rotating handle 33. Through the provision of the crank and the rotating handle, the effect of fast tightening and disassembly can be achieved.

[0030] Preferably, the tube connection unit 2 is connected to a delivery tube 4. The delivery tube is in communication with a gas source or a liquid source and is used to deliver the fluid to be perfused.

[0031] Furthermore, the outer frame is a square structure surrounded by side plates 11 and end plates 12, and the pipe connection unit 2 and the rotation fixing unit 3 are respectively arranged on two symmetrical end plates 12 of the outer frame 1, and the side plate 11 is also provided with a weight-reducing hole 12. This frame structure is designed to be simple and practical, which can not only provide sufficient support, but more importantly, the effective structure can improve the overall stability. The pipe connection unit 2 and the rotation fixing unit 3 are arranged on two symmetrical end plates 12 of the outer frame. This symmetrical layout can make the force more evenly distributed on the equipment, reduce the vibration caused by imbalance, and increase the service life of the equipment. The weight-reducing hole 12 on the side plate 11 is a good design, which aims to reduce the weight of the equipment, thereby improving the portability and flexibility of the equipment.

[0032] In addition, as a specific embodiment, the pipe connection unit 2 includes an inner cavity 23 formed by an outer sleeve 21 and a head 22, the inner cavity is provided with an inner core 25 pushed by a spring 24, an inner sealing ring 251 is provided in the middle of the inner core 25 to form a seal with the inner wall of the inner cavity 23 near the head 22, a front core segment 252 of the inner core extends out of the outer sleeve 21 and is provided with a core head 253 matching the inside of the valve port 200 of the valve 100, and a through hole 255 is provided on the front core segment 252 and the rear core segment 254. When the inner core compresses the spring under the pressure of an external force and moves toward the inner cavity, the through holes 255 of the front core segment 252 and the rear core segment 254 are both connected to the inner cavity 23. The diameter of the core head 253 is larger than the diameter of the front core segment 252, and the diameter of the rear core segment 254 is larger than the diameter of the front core segment 252. A sealing member 26 is provided between the head 22 and the outer sleeve 21. The inner cavity 23 is divided into a straight section 231 and an expansion section 232 , and the straight section 231 of the inner cavity is transitionally matched with the rear core section 254 of the inner core.

[0033] The pipe connection unit includes an inner cavity 23 formed by an outer sleeve 21 and a sealing head 22. An inner core 25 pushed by a spring 24 is installed in the inner cavity. For the inner core 25, an inner sealing ring 251 is provided in the middle part, which forms a seal with the inner wall of the inner cavity near one end of the sealing head, which can effectively prevent the leakage of liquid or gas. In addition, the front core segment 252 of the inner core can extend out of the outer sleeve and is provided with a core head 253 matching the inside of the valve port of the valve. The design of this core head enables the valve to better control and regulate the fluid. At the same time, through holes 255 are provided on the front core segment and the rear core segment, and when the inner core is compressed by external force, these two through holes can communicate with the inner cavity. This is a unique design that allows the pipe connection unit to be quickly opened or closed when needed. The size issue is taken into consideration in the design, and the diameter of the core head is set to be larger than the diameter of the front core segment, and the diameter of the rear core segment is also set to be larger than the diameter of the front core segment. Such a design can ensure the stability of the spring and the inner core and reduce the switching resistance of the valve. The inner cavity is divided into a straight section and an expansion section, in which the straight section and the rear core section of the inner core are transitionally matched, which can ensure the stability of the inner core when moving and improve the sealing performance of the valve.

[0034] Through the structural design of the pipe connection unit, it is achieved that when no external force is applied, the inner core is squeezed by the spring and self-sealed with the outer sleeve through the inner sealing ring. When the inner core matches the valve port of the valve, the core head of the inner core enters the valve port. As the top head continues to be squeezed, the valve port is connected to the flow channel of the quick connection device.

[0035] The embodiments described above are merely descriptions of preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
