Quick positioning low-temperature liquid filling universal adjusting device

Abstract

This utility model discloses a rapid positioning universal adjustment device for cryogenic liquid filling, relating to the technical field of positioning adjustment devices. It includes a connector tube with a metal flexible hose connection end at one top end and a socket end at the other. The connector tube is inserted into the tank interface end through the socket end. An arc-shaped abutment rod passes behind the socket end. Because the internal threaded cylinder slides within the annular grooves of outer plates one and two via a ball head, it can only rotate in a limited manner. The threaded connection between the internal threaded cylinder and the threaded rod allows the internal threaded cylinder to hook onto the end of the tank's socket port furthest from the connector tube after rotation. One end of the tank is inserted into the connector tube, and the other end is hooked onto the arc-shaped abutment rod, creating a positioning effect. Compared to traditional fixing methods, this allows for faster installation during filling and faster disassembly after filling, and is simple and convenient to operate.

Description

Technical Field

[0001] This utility model relates to the technical field of positioning and adjustment devices, and in particular to a cryogenic liquid filling universal adjustment device that can be quickly positioned. Background Technology

[0002] When filling cryogenic liquids, in order to facilitate the flexible installation of the filling connector and the tank interface, the pipeline is usually set as a metal gooseneck tube. The flexibility of the gooseneck tube allows for universal adjustment of the filling connector position.

[0003] When the connector is inserted into the inflation pipe of the tank and inflation begins, a positioning device is needed to fix the connector pipe to the tank or the position of the tank on the inflation pipe. The traditional positioning device consists of two parts: the first part is fixed to the connector, and the second part is fixed to the inflation pipe or the tank. Then, both parts are fixed. Although this positioning method has a certain positioning effect, it is cumbersome and time-consuming, and cannot achieve the purpose of rapid positioning. Utility Model Content

[0004] The main objective of this invention is to provide a rapidly positioning universal adjustment device for filling cryogenic liquids, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A rapidly positioning cryogenic liquid filling universal adjustment device includes a connector tube. One end of the connector tube has a metal flexible hose connection end, and another end has a socket end. A positioning mechanism is located at the end of the connector tube near the socket end. The positioning mechanism includes a fixed sleeve. A supporting sleeve is fixed to one end of the outer wall of the fixed sleeve. A threaded rod slides through the interior of the supporting sleeve. An arc-shaped abutment is fixed to one end of the threaded rod passing through the supporting sleeve. An outer plate two is fixed to the other end of the outer wall of the fixed sleeve. An outer plate one is located on the outer wall of the supporting sleeve near the outer plate two. An internally threaded cylinder is located between the outer plate one and the outer plate two. Several equidistant ball heads are fixed to the outer walls of both sides of the internally threaded cylinder. Annular grooves are carved on the sides of the outer plates one and two that are close to each other. A plate hole is carved on the side wall of the outer plate two.

[0007] Preferably, the end of the threaded rod away from the arc-shaped abutment is threaded through the internal threaded cylinder and then connected.

[0008] Preferably, the threaded rod passes through one end of the internally threaded cylinder and slides through the plate hole.

[0009] Preferably, the fixing sleeve is fitted onto the outer wall of the metal flexible hose connection end welded to the insertion end.

[0010] Preferably, the ball heads on both sides of the internal threaded cylinder are respectively inserted into the annular grooves of outer plate one and outer plate two and are slidably connected to them.

[0011] Preferably, the outer wall of the internally threaded cylinder is fixed with several handles.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The connector tube of this device is inserted into the interface end of the tank through the plug end. The arc-shaped abutment rod goes around the back of the plug end. Since the internal threaded cylinder slides in the annular groove of the outer plate one and the outer plate two through the ball head, it can only rotate in a limited position. The threaded connection between the internal threaded cylinder and the threaded rod allows the internal threaded cylinder to hook the end of the tank plug port away from the connector tube after rotation. One end of the tank is inserted into the connector tube, and the other end is hooked with the arc-shaped abutment rod, forming a positioning effect. Compared with the traditional fixing method, it can complete the installation during filling and the disassembly after filling more quickly, and the operation is simple and convenient.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, a rapid-positioning cryogenic liquid filling universal adjustment device includes a connector tube 1. A metal flexible hose connection end 11 is provided at one top end of the connector tube 1, and a socket end 12 is provided at the other top end of the connector tube 1. A positioning mechanism 2 is provided at the end of the connector tube 1 near the socket end 12. The positioning mechanism 2 includes a fixing sleeve 21, and a supporting sleeve 22 is fixed to one end of the outer wall of the fixing sleeve 21. A threaded rod 28 slides through the inside of the supporting sleeve 22. One end of the sleeve 22 is fixed with an arc-shaped abutment rod 29, and the other end of the outer wall of the fixed sleeve 21 is fixed with an outer plate 24. The outer wall of the supporting sleeve 22 near the outer plate 24 is provided with an outer plate 23. An internal threaded cylinder 26 is provided between the outer plate 23 and the outer plate 24. Several equidistant ball heads 27 are fixed on both sides of the outer wall of the internal threaded cylinder 26. An annular groove 25 is drilled on the side of the outer plate 23 and the outer plate 24 that are close to each other. A plate hole 241 is drilled on the side wall of the outer plate 24.

[0021] Specifically, the end of the threaded rod 28 away from the arc-shaped abutment 29 is threaded through the internal threaded cylinder 26 and then connected by a thread.

[0022] Specifically, the threaded rod 28 passes through one end of the internal threaded cylinder 26 and slides through the plate hole 241.

[0023] Specifically, the fixing sleeve 21 is fitted and welded to the outer wall of the metal flexible hose connection end 11 at the socket end 12.

[0024] Specifically, the ball heads 27 on both sides of the internal threaded cylinder 26 are respectively inserted into the annular grooves 25 of the outer plate 1 23 and the outer plate 24 and slidably connected with them, so that the internal threaded cylinder 26 can be limited to rotate. The forward and reverse rotation of the internal threaded cylinder 26 can drive the threaded rod 28 to move back and forth as required for disassembly and assembly.

[0025] Specifically, the outer wall of the internally threaded cylinder 26 is fixed with several handles 210 to facilitate the rotation of the internally threaded cylinder 26.

[0026] Working principle:

[0027] The connector tube 1 of this device is inserted into the interface end of the tank through the plug end 12. The arc-shaped abutment rod 29 passes around the back of the plug end. Since the internal threaded cylinder 26 slides in the annular groove 25 of the outer plate 1 23 and the outer plate 24 through the ball head 27, it can only rotate in a limited position. The threaded connection between the internal threaded cylinder 26 and the threaded rod 28 allows the internal threaded cylinder 26 to hook the end of the tank plug port away from the connector tube 1 after rotation. One end of the tank is inserted into the connector tube 1, and the other end is hooked with the arc-shaped abutment rod 29 to form a positioning effect. Compared with the traditional fixing method, it can complete the installation during filling and the disassembly after filling more quickly, and the operation is simple and convenient.

[0028] The metal flexible hose connection end 11 of the connector tube 1 is connected to the metal gooseneck tube, which will not be described in detail in this application.

[0029] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
