Description

Technical Field

[0001] This utility model relates to the field of plastic pipe construction technology, and in particular to an external support device for connecting steel wire mesh reinforced pipes and water supply pipes. Background Technology

[0002] During the construction and connection of existing PE steel wire mesh pipes and PE water supply pipes, whether through hot-melt or electrofusion fittings, the non-roundness of the pipes is subject to significant requirements. However, due to the influence of production processes, cooling, self-weight, and the disorientation of polyethylene molecular chains during production and storage, the non-roundness of the pipes cannot be effectively guaranteed. This results in frequent problems during pipe construction and connection, such as pipe mismatch in hot-melt connections, inability to insert fittings into electrofusion connections, and large gaps after pipe insertion. Utility Model Content

[0003] This utility model provides an external support device for the construction of steel wire mesh reinforced pipe and water supply pipe connection, which can solve the problems that often occur in the prior art when pipe construction and connection, such as mismatch of hot-melt connection pipes, inability to insert electrofusion fittings, and large gaps after pipes are inserted into fittings.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An external support device for connecting steel wire mesh reinforced pipes and water supply pipes includes an upper arc block, a lower arc block, and a large-diameter screw. The upper and lower arc blocks are arranged symmetrically. One end of the large-diameter screw is rotatably mounted on the lower arc block, and the other end is threaded with a threaded locking cap for locking the upper arc block onto the lower arc block. Both ends of the upper arc block are provided with screw clips that penetrate and engage the large-diameter screw. The rotation of the threaded locking cap causes the upper and lower arc blocks to move relative to each other to clamp and round the pipe.

[0006] As a further embodiment of this utility model: both ends of the upper inner side of the lower arc block are provided with limit slots, and both ends of the upper arc block are provided with limit inserts corresponding to the limit slots.

[0007] As a further embodiment of this utility model: the large-diameter screw is fixed to the lower arc block by a screw fixing rod.

[0008] As a further embodiment of this utility model: the contact surface between the upper arc block and the lower arc block is an arc-shaped surface adapted to the outer wall of the pipe.

[0009] As a further embodiment of this utility model, the large-diameter screw is a trapezoidal thread screw.

[0010] As a further embodiment of this utility model: the screw clip has a U-shaped structure that covers the head of a large-diameter screw.

[0011] As a further embodiment of this utility model, anti-slip textures are provided on the arc surfaces of the upper and lower arc blocks.

[0012] As a further embodiment of this invention, the device further includes an elastic buffer layer disposed between the upper arc block and the lower arc block.

[0013] As a further aspect of this invention: the screw fixing rod allows the large-diameter screw to rotate but restricts its axial movement.

[0014] As a further embodiment of this utility model, the upper arc block and the lower arc block are made of stainless steel.

[0015] The beneficial effects of this utility model are as follows: by using external support, the out-of-roundness of the pipe is corrected by the displacement of the arc block; the external rounding action can solve the problem of large out-of-roundness of the pipe, thereby making the bonding with the electrofusion fitting more reliable and the hot melt flanging better.

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.

[0024] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figures 1-4 As shown, this utility model is an external support device for connecting steel wire mesh reinforced pipes and water supply pipes. It includes an upper arc block 1, a lower arc block 5, and a large-diameter screw 2. The upper arc block 1 and the lower arc block 5 are arranged symmetrically. One end of the large-diameter screw 2 is rotatably installed on the lower arc block 5, and the other end is threaded with a threaded locking cap 21 for locking the upper arc block 1 onto the lower arc block 5. Both ends of the upper arc block 1 are provided with screw clips 3 that penetrate and engage the large-diameter screw 2. The rotation of the threaded locking cap 21 causes the upper arc block 1 and the lower arc block 5 to move relative to each other to clamp and round the pipe.

[0027] In an optional embodiment, the lower arc block 5 is provided with limit slots 51 at both ends of the upper inner side, and the upper arc block 1 is provided with limit inserts 11 corresponding to the limit slots at both ends.

[0028] It should be noted that by setting the limit slot 51 and the limit plug 11 to cooperate, on the one hand, the stability of the cooperation between the upper arc block 1 and the lower arc block 5 is improved, and the radial limit of the limit slot 51 and the limit plug 11 ensures the stability of the cooperation, and on the other hand, the effect of making the round tube round is ensured.

[0029] In an optional embodiment, the large-diameter screw 2 is fixed to the lower arc block 5 by a screw fixing rod 4. The screw fixing rod 4 allows the large-diameter screw 2 to rotate but restricts its axial movement. Specifically, the rotation direction of the large-diameter screw is perpendicular to the displacement direction of the screw fixing rod 4.

[0030] It should be noted that the large-diameter screw 2 is fixed to the lower arc block or device base by the screw fixing rod 4. The screw fixing rod 4 allows the large-diameter screw 2 to rotate but restricts its axial movement, ensuring that the large-diameter screw 2 remains stable during rotation. The vertical transmission structure ensures that the rounding force is evenly distributed and eliminates the difference in flange thickness.

[0031] In an optional embodiment, the contact surface between the upper arc block 1 and the lower arc block 5 is an arc-shaped surface adapted to the outer wall of the pipe.

[0032] It should be noted that the contact surface between the upper arc block 1 and the lower arc block 5 is an arc-shaped surface that is adapted to the outer wall of the pipe, which can better fit the pipe and improve the roundness effect.

[0033] In an optional embodiment, the large-diameter screw 2 is a trapezoidal thread screw.

[0034] It should be noted that trapezoidal threaded screws have high strength and transmission efficiency, thus improving the working efficiency of the device.

[0035] In an optional embodiment, the screw clip 3 has a U-shaped structure that covers the head of the large-diameter screw 2.

[0036] It should be noted that the U-shaped buckle facilitates the installation and adjustment of the large-diameter screw 2, and also limits the movement of the large-diameter screw 2 on both sides, improving the convenience and stability of the device.

[0037] In an optional embodiment, anti-slip textures are provided on the arc surfaces of the upper arc block 1 and the lower arc block 5.

[0038] It should be noted that the anti-slip textures on the curved surfaces of the upper arc block 1 and the lower arc block 5 can increase the friction between them and the pipe, preventing the pipe from sliding during the process of forming a circle.

[0039] In an optional embodiment, the device further includes an elastic buffer layer disposed between the upper arc block 1 and the lower arc block 5.

[0040] It should be noted that the elastic buffer layer can buffer the impact force during the rounding process and protect the pipe from damage.

[0041] As a further embodiment of this utility model, the upper arc block 1 and the lower arc block 5 are made of stainless steel.

[0042] It should be noted that the upper arc block 1 and the lower arc block 5, made of stainless steel, have high strength and corrosion resistance, and can adapt to harsh construction environments.

[0043] The working principle of this invention is as follows: The pipe is placed between the upper arc block 1 and the lower arc block 5. The threaded locking nut 21 connected to the end of the large-diameter screw 2 is rotated. The large-diameter screw 2 is in the screw clip 3, and under the action of the threaded locking nut 21, the upper arc block 1 moves downward, clamping the pipe between the upper arc block 1 and the lower arc block 5. Continuing to rotate the threaded locking nut 21, the upper arc block 1 and the lower arc block 5 apply a uniform external force to the pipe, correcting its out-of-roundness. After rounding is complete, the threaded locking nut 21 is rotated in the opposite direction, causing the upper arc block 1 and the lower arc block 5 to loosen the pipe, allowing it to be removed.

[0044] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
