Description

Technical Field

[0001] The utility model relates to the technical field related to steel-plastic pipeline connection, in particular to a steel-plastic pipeline connection fixing device. Background Art

[0002] Steel-plastic pipes are generally set up as hollow circular structures. They can be used for the transportation of oil, gas and chemical materials. Not only liquids but also gases can be transported inside them. With the continuous development of the economy, when steel-plastic pipes are used, the length of the processed pipes is generally not conducive to long-distance transmission. Therefore, when using the pipes, a large number of pipes are generally transported to the installation location, and then the two adjacent pipes are fixed by fixing devices before the long-distance transmission of gas and liquids can be carried out. There are steel-plastic pipe connection devices on the market. When connecting, it is necessary to align the two pipes in advance before the pipes can be fixed. Therefore, its fixing method is to fix the two pipes externally, and there is no auxiliary control between the two pipes. The two pipes are then fixed. Due to the uncertainty of various factors in the on-site environment at the construction site, the operation is too difficult when controlling the equal height alignment between the connecting pipes, and the whole process is also very time-consuming. Utility Model Content

[0003] The purpose of the utility model is to provide a steel-plastic pipe connection and fixing device to solve the problem that the pipe connection and fixing device currently on the market proposed in the above background technology can only fix two pipes, and cannot quickly control the two pipes on the construction site to quickly connect and then fix them, thereby resulting in a lot of time being wasted when connecting and fixing the pipes.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a steel-plastic pipe connection and fixing device, comprising a fixing seat, which is arranged in a rectangular structure and has a hollow structure extending through the middle thereof;

[0005] Also includes;

[0006] There are two pipe bodies, which are respectively arranged on both sides of the fixing seat;

[0007] The pipe openings of the two pipe bodies penetrate the circular hollow structure passing through the middle of the fixing seat;

[0008] The outside of the fixing seat is provided with a snap-fit ​​mechanism for connecting two pipe bodies.

[0009] Preferably, the pipeline body includes a connecting pipeline and a mounting flange, and the top end of the connecting pipeline is integrally mounted with the mounting flange;

[0010] A plurality of through holes are distributed at equal angles on the outside of the mounting flange.

[0011] Preferably, a mounting screw is provided in the through hole at the top end of the mounting flange, which is used for connecting the mounting flange to the outer wall of the fixing seat.

[0012] Preferably, the engaging mechanism is symmetrically installed on both sides of the fixing seat, and comprises an engaging column and an extrusion plate. The engaging column is provided with a cylindrical structure, and an extrusion plate with an inclined cross section is provided on the outside thereof.

[0013] The extrusion plates are distributed in an arc shape, and rubber sealing pads are arranged on the outside of the extrusion plates.

[0014] Preferably, a limit plate with an inclined cross-section is provided on the inner wall of the pipe mouth of the pipe body, and the limit plate is also distributed in a ring shape. The limit plate can be engaged with the extrusion plate to squeeze and limit, so as to achieve the effect of controlling the connection between the pipe body and the fixed seat.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the steel-plastic pipe connection and fixing device changes the traditional fixing method and is directly set in the middle of the two pipes, and the two pipes are controlled to be connected and fixed to the two sides of the fixing seat respectively. Afterwards, the connection work of the two pipes can be directly completed through the hollow structure setting inside the fixing seat. Moreover, since the two pipes are fixed at the two sides of the fixing seat, the connection and fixing work of the pipes can be completed at the same time. The whole process does not require the direct alignment work of the connected pipes, and even if the two connected pipes are not in the same straight line, it will not affect the connection work of the two.

[0016] When the locking mechanism on the fixing seat is locked with the pipe mouth of the connecting pipe, due to the extrusion sealing work between the extrusion plate and the limit plate, it can also ensure that when the pipe is connected and fixed through the fixing seat, there will be no pipe leakage problem compared with the traditional connection between two pipes. The operation is simple and it can also ensure that the connected pipes can perform efficient transmission. BRIEF DESCRIPTION OF THE DRAWINGS
