Description

TECHNICAL FIELD

[0001] The utility model relates to cable bus pouring pipe's control switch device, specifically relates to a kind of insulated bus pouring pipe pipe clamp, it is applied to epoxy resin vacuum impregnated paper solid insulation tubular bus pouring pipe product. BACKGROUND

[0002] For epoxy resin vacuum impregnated paper solid insulation tubular bus pouring pipe product, when pouring production, the flow size degree of epoxy resin injection in pouring silicone tube and the closing of pouring pipe need to be controlled.In the structure setting of conventional pipe clamp, pipe clamp needs to be installed on pouring pipe, but the slider and the body of pipe clamp need to be disassembled to install pouring pipe, which undoubtedly increases installation and disassembly steps, increases installation and disassembly difficulty, wastes time and reduces work efficiency. UTILITY MODEL CONTENT

[0003] In view of the above technical problems, the utility model aims at providing a kind of insulated bus pouring pipe pipe clamp, which uses movable extruding piece to extrude pouring pipe to change the diameter of pouring pipe, and then realizes the control of pouring pipe diameter or complete closure to control the flow of epoxy resin in pipe.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme: a kind of insulated bus pouring pipe pipe clamp, comprising: body, the body is half open type board half frame structure, extruding piece is movably arranged on the open side of half frame, pouring pipe is contained in the inside of the closed side of half frame, the bottom of extruding piece is towards pouring pipe, nut is arranged on the body in the direction of the top of extruding piece, and the nut is threadedly connected with the body;

[0005] Further, the body of half frame structure is formed by twice right-angle bending of a cylindrical pipe, and the end heads of the two free ends of the pipe are towards the same direction, and the height of the end head of one free end is higher than that of the other free end;

[0006] Further, the extruding piece and the nut above it are arranged in the area with relatively high height of the free end of the body;

[0007] Further, the space formed by twice right-angle bending of the body is on the closed side of half frame, and the space is used for accommodating pouring pipe.

[0008] Further, the outer surface of the area of the body connecting extruding piece and nut is provided with external thread area, the extruding piece is provided with thread hole matched with the diameter of the body, and the extruding piece is connected to the body by screwing;

[0009] Furthermore, the extruded part is a concave semi-frame body, which is formed by bending two opposite sides of a horizontal plate; the two bent sides form an upper horizontal side and a lower horizontal side respectively, and a vertical back plate is between them; upper holes and lower holes are correspondingly opened on the upper horizontal side and the lower horizontal side.

[0010] Furthermore, the upper and lower holes have the same diameter and are both larger than the outer diameter of the external thread area of ​​the card body.

[0011] In this solution, the pipe clamp is limited by the width of the compression space on one side of the semi-enclosed side of the extruder. When the extruder moves downward, in order to avoid the lower horizontal edge of the extruder from colliding with the side of the free end of the clamp body that is relatively lower, the side edge of the lower horizontal edge of the extruder forms a gap area relative to the outer edge of the vertical back plate. This gap area is the position occupied by the extruder when it moves downward, thereby preventing the extruder from colliding with the clamp body.

[0012] Furthermore, another aspect of this design is that the extrusion member is fitted onto the external threaded area of ​​the card body through two holes, forming a rotatable structure relative to the card body; in the rotatable structure, one end of the empty area of ​​the vertical back plate is the free end, and the end of the vertical back plate that is fitted onto the external threaded area of ​​the card body is the connecting end.

[0013] Through the function of this rotating structure, when the pipe clamp is installed on the casting pipe, it is only necessary to rotate the extrusion component, so that the free end of the vertical back plate of the extrusion component rotates around the connection end as the rotation center. This causes the empty area of ​​the vertical back plate of the extrusion component to leave the clamp body, opening the extrusion space of the casting pipe, and the pipe clamp can be installed on the casting pipe. There is no need to remove the extrusion component and the clamp body for installation, thus achieving convenient installation, simple disassembly, and saving a lot of installation time.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this solution, a movable extrusion component is used to change the diameter of the casting pipe, thereby controlling the flow rate of epoxy resin inside the pipe. This serves as a control switch, and the extrusion component is designed to be rotatable. By rotating the extrusion component, all parts can be installed on the pipeline without completely removing the pipe clamp, thus achieving convenient installation, simple disassembly, and saving a lot of installation time.

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] like Figures 1-10 The shown is an insulating busbar casting pipe clamp, comprising: a clamp body 1, wherein the clamp body 1 is a semi-open plate and semi-frame structure, an extrusion member 2 is movably arranged on the open side of the semi-frame, and a casting pipe 3 is contained inside the closed side of the semi-frame, the bottom of the extrusion member 2 faces the casting pipe 3, and a nut 4 is provided on the clamp body 1 located at the top of the extrusion member 2, and the nut 4 is threadedly connected to the clamp body 1.

[0029] Furthermore, the card body 1 of the semi-frame structure is formed by bending a cylindrical tube twice at right angles, and the two free ends of the tube face the same direction, with the height of one free end being higher than the height of the other free end.

[0030] Further, the extrusion piece 2 and the nut 4 above it are arranged in the area of the free end of the card body 1 which has a relatively high height;

[0031] Further, the area space formed by the secondary right-angle bending of the card body 1 is the side of the half-frame closure, which is used to accommodate the pouring pipe 3.

[0032] Further, the outer threaded area 1.2 is arranged on the area outer surface of the card body 1 which connects the extrusion piece 2 and the nut 4, the extrusion piece 2 is provided with a hole which matches the diameter of the card body 1, and the extrusion piece 2 is connected to the card body 1 in a screwing manner;

[0033] Specifically, the diameter of the outer threaded area 1.2 of the card body is 6 mm, and the nut 4 is internally provided with an inner threaded hole with a specification of M6, which matches the card body 1.

[0034] It should be noted that the length of the outer threaded area 1.2 of the card body is much greater than the sum of the height of the extrusion piece 2 and the height of the nut 4, and the purpose is to use the nut 4 to have a certain moving stroke amount of the extrusion piece 2 on the card body 1, so as to facilitate the extrusion piece 2 to have a corresponding extrusion deformation amount of the pouring pipe 3, and to realize the change of the pipe diameter of the pouring pipe 3.

[0035] Specifically, the height of the extrusion piece 2 is 24 mm, the height of the nut 4 is 18 mm, and the length of the outer threaded area 1.2 of the card body is 55 mm.

[0036] Further, the extrusion piece 2 is a concave half-frame body which is formed by bending the opposite two sides of a horizontal plate; the two bent sides form the upper horizontal side 2.1 and the lower horizontal side 2.1 respectively, and the vertical back plate 2.3 is between the two; the upper hole 2.4 and the lower hole 2.5 are arranged on the upper horizontal side 2.1 and the lower horizontal side 2.2 respectively; during installation, the extrusion piece 2 is penetrated through the outer threaded area 1.2 of the card body through the upper hole 2.4 and the lower hole 2.5, so that the lower bottom surface of the lower horizontal side 2.2 is close to the pouring pipe 3, and the upper top surface of the upper horizontal side 2.1 is close to the nut 4.

[0037] During use, the extrusion piece 2 is extruded by the screwing connection between the nut 4 and the card body 1, so as to force the extrusion piece 2 to move downward and generate displacement; the lower horizontal side 2.2 of the extrusion piece 2 is in contact with the outer wall of the pouring pipe 3, and the lower bottom surface of the lower horizontal side 2.2 of the extrusion piece 2 and the inner wall of the half-frame closure side of the card body 1 form an extrusion space 5; and then the pouring pipe 3 is forced to be extruded and deformed in the card body 1, so as to change the inner diameter size of the pouring pipe 3.

[0038] Further, the diameters of the upper hole 2.4 and the lower hole 2.5 are the same and are greater than the outer diameter of the outer threaded area 1.2 of the card body, and in the embodiment, the upper hole 2.4 and the lower hole 2.5 are Φ6.5 mm; the thickness of the extrusion piece 2 is 2 mm.

[0039] In this scheme, the tube card is limited by the extrusion space width 5 of the half-frame closed side of the extrusion piece 2. When the extrusion piece 2 moves downward, in order to avoid the conflict between the lower horizontal edge 2.2 of the extrusion piece 2 and the side of the card body 1 with a lower free end height, the side edge of the lower horizontal edge 2.2 of the extrusion piece 2 forms a vacant area 6 relative to the outer edge of the vertical back plate 2.3. The vacant area 6 is the position occupied by the extrusion piece 2 when it moves downward, thereby preventing the conflict between the extrusion piece 2 and the card body 1.

[0040] Further, another concept of the scheme is that the extrusion piece 2 is sleeved on the outer threaded area 1.2 of the card body through the upper and lower holes, forming a rotatable structure relative to the card body 1. In the rotatable structure, one end of the vacant area 6 of the vertical back plate 2.3 is a free end, and the other end of the vertical back plate 2.3 sleeved on the outer threaded area 1.2 of the card body is a connected end.

[0041] Through the action of the rotating structure, when the tube card is installed on the pouring pipe 3, only the extrusion piece 2 needs to be rotated, and the free end of the vertical back plate 2.3 of the extrusion piece 2 is rotated around the connected end as the center, so that the vacant area 6 of the vertical back plate 2.3 of the extrusion piece is away from the card body 1, and the extrusion space 5 of the pouring pipe 3 is opened, so that the tube card can be installed on the pouring pipe 3; without disassembling the extrusion piece 2 and the card body 1 for installation.

[0042] The tube card structure of the embodiment is used to rotate the extrusion piece 2 counterclockwise to install the tube card on the pouring pipe 3, and then rotate the extrusion piece 2 clockwise after installation to close the extrusion space 5 of the tube card pouring pipe. By rotating the nut 4 downward, the nut 4 moves downward to make the extrusion piece 2 close to the pouring pipe 3. By gradually moving the extrusion piece 2 downward, the pouring pipe 3 is deformed, the size of the inner diameter of the pouring pipe 3 is changed, and the control of the epoxy resin flow is realized.

[0043] The principle of the scheme is to extrude the extrusion piece 2 through the threaded connection between the nut 4 and the card body 1, so as to control or completely close the tube diameter, and to reduce the installation and disassembly difficulty through the rotatable extrusion piece 2. The key protection point is that the assembly and disassembly are simple, safe and reliable, reusable, energy-saving and environment-friendly.
