Description

Technical Field

[0001] This utility model belongs to the field of pipe fittings technology and relates to a liquid filling pipe assembly. Background Technology

[0002] Liquid dispensers are used for quantitative liquid dispensing and are commonly used in the chemical and mechanical industries. They mainly consist of a shell, a liquid storage structure, a liquid injection structure, an intelligent control structure, a liquid outlet pipe, and a liquid outlet connector. In actual use, the connector needs to be connected to the pipe or other components, which is generally done manually. After connection, the connector still needs to be held manually. If the operating system is too far away, a single person cannot operate it effectively, resulting in low efficiency. At the same time, after dispensing, the connector is separated from the pipe, resulting in a certain amount of waste, thus failing to meet the usage requirements. Summary of the Invention

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1 , Figure 2As shown, this liquid filling tube assembly includes a connector body 1 with an output end and an input end. A liquid filling tube is fitted to the output and input ends of the connector body 1. A check valve unit with a check function is provided at the opening of the output end of the connector body 1. A connecting assembly is provided on the connector body 1 and is connected to the fitting for quick connection. This connecting assembly includes a clamping unit for clamping the assembled fitting and a control unit for controlling the operation of the clamping unit. The clamping unit includes a housing tube 2 sleeved on the connector body 1 and several clamping claw blocks 3 disposed on and movably connected to the housing tube 2 for clamping the fitting. Several radially outward protrusions are provided on the inner circumferential wall of the housing tube 2, and are coaxially arranged, leaving a gap between the housing tube 2 and the connector body 1. The outer casing tube 2 has several circumferentially spaced mounting slots on its outer peripheral wall at the output end of the connector body 1, which are spaced apart for mounting corresponding gripper blocks 3. The control unit includes a fixed plate 5, a movable plate 6, a control sleeve 7, and two movable handrails 8. The fixed plate 5 is fitted onto and connected to the connector body 1, the movable plate 6 is fitted onto and connected to the outer casing tube 2, and both movable handrails 8 are mounted on and connected to the movable plate 6. Both movable handrails 8 are connected to the fixed plate 5 through a connecting unit one. The control sleeve 7 is fitted onto and slidably engages with the outer casing tube 2. The control sleeve 7 is connected to the fixed plate 5 through a connecting unit two. By controlling the movable handle, the movable sleeve is moved axially, and the grippers... The position of block 3 moves accordingly, and through cooperation with control sleeve 7, the clamping and releasing of gripper block 3 are realized. The check unit includes check sleeve 9 and limit sleeve 10. Limit sleeve 10 is disposed inside and connected to the connector body 1. The limit sleeve 10 is coaxially arranged with the connector body 1, and a radially outward protruding convex ring 2 is provided on the outer peripheral wall of the limit sleeve 10. The convex ring 2 leaves a gap between the outer peripheral wall of the limit sleeve 10 and the inner peripheral wall of the connector body 1. Check sleeve 9 is also disposed inside the connector body 1 and slides with it. Check sleeve 9 is also coaxially arranged with the connector body 1, and the check sleeve 9 is composed of a plug head and a bushing part connected to the plug head. The outer peripheral wall of the plug head is set in a frustum conical structure, and a section is opened on the outer peripheral wall at the connection between the bushing part and the plug head. Several through holes are spaced apart along their circumference. A sealing ring is fitted onto the plug head. A radially outward-protruding contact ring 11 is provided on the inner circumferential wall of the connector body 1 at the output end, abutting against the check sleeve 9. The inner end face of the contact ring 11 is inclined. An annular groove is formed on the inner circumferential wall of the connector body 1 at the through hole in the check sleeve 9, facilitating the flow of liquid or gas after the check sleeve 9 is pushed open. Several radially outward-protruding convex rings 12 are provided on the outer circumferential wall of the bushing portion, spaced apart along its axial length. The check sleeve 9 slides with the connector body 1 through the convex rings 12. A sealing ring is fitted onto the convex rings 12 to enhance sealing. When the check sleeve 9 is pushed open and retracted, the bushing portion slides with the limiting sleeve 10.This puts the connector body 1 in the open state. An installation unit is provided between the control sleeve 7 and the outer casing tube 2 to facilitate the installation of the control sleeve 7. This installation unit includes a connecting ring 14 fitted onto the outer casing tube 2 and an aluminum ring 15 fitted onto the connecting ring 14 for the control sleeve 7 to install. The outer peripheral wall of the connecting ring 14 has a radially outward-protruding convex ring 16 that connects to the aforementioned connecting unit 2. This convex ring 16 also facilitates the installation of the aluminum ring 15. The outer peripheral wall of the control sleeve 7 has several circumferentially spaced, easily observable, strip-shaped grooves. The inner peripheral wall of the outer end of the control sleeve 7 has a convex ring 17 that mates with the gripper block 3. Both ends of the convex ring 17 are inclined surfaces. The outer wall of the gripper block 3 at its inner end has a radially outward-protruding protrusion that mates with its convex ring 17. The inner wall of the gripper block 3 at its inner end has an inclined surface. The connecting unit 1 includes two connecting pieces 1. The connector includes a movable frame 8 and two connecting shafts 19, which are respectively mounted on and connected to the movable frame 8 and the fixed plate 5. Both ends of the connecting shafts 19 extend beyond the sides of the movable frame 8 and the fixed plate 5. Mounting holes for the corresponding connecting shafts 19 are provided on both ends of the fixed plates 5. When the pipe fitting is connected to the connector body 1, the movable frame 8 is manually controlled to move the outer casing tube 2 axially, thereby pressing the clamping block 3 against the connection between the pipe fitting and the connector body 1, thus putting the connector body 1 into a working state. When it needs to stop working, the movable frame 8 is manually controlled to reset, thereby releasing the clamping block 3 from the pipe fitting. Simultaneously, the output end is closed by hydraulically controlled check valve, allowing the connector body 1 and the pipe fitting to be quickly connected and separated, achieving precise quantity control. The connecting unit two includes several connecting rods 20, both ends of which are connected to the convex ring 16 and the fixed plate 5, respectively.

[0018] As a preferred structure, a sealing ring is also fitted on the outer peripheral wall of the connector body 1 at the output end.

[0019] As a preferred structure, the gripper block 3 is connected to the outer shell tube 2 via a pin 13, and the movable hand frame 8 is also connected to the movable plate 6 via a pin 13.
