Description

Technical Field

[0001] This utility model relates to the field of pipeline docking technology, and more specifically to a pipeline docking mechanism. Background Technology

[0002] In industrial piping systems, flange connections are a widely used method for pipe connection. They achieve a sealed connection by placing two flanges face-to-face and tightening them with bolts, ensuring the safe and stable operation of the piping system. However, in actual installation, existing flange connection methods have some inconveniences, especially the additional steps required during bolt tightening, which increases construction difficulty and time costs.

[0003] Traditional flange connections typically require two hands to tighten the bolts: one hand uses a wrench to hold the bolt in place to prevent it from rotating, while the other hand uses a torque wrench to tighten it.

[0004] Therefore, it is necessary to propose a pipeline connection mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that traditional flange connections usually require two hands to work together when tightening bolts, with one hand using a wrench to fix the bolt to prevent it from rotating, and the other hand using a torque wrench to tighten it.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A pipe connection mechanism includes a pipe with a flange, the flange having multiple bolt holes, the flange edge having a notch communicating with the bolt holes, a bolt being inserted into the bolt holes, a positioning strip being fixedly connected to the outer side of the bolt being insertable into the notch, a baffle being fitted onto the other end of the bolt being, and a nut being threaded onto the bolt being at that end for pressing the baffle tightly against the flange.

[0008] Furthermore, a pressure plate that is attached to the outer side of the flange is fixedly connected to the upper end of the baffle, and an insert plate that can be inserted into the notch is fixedly connected to the lower end of the pressure plate.

[0009] Furthermore, a square block is fixedly connected to the upper hexagonal end of the bolt, and a plug is fixedly connected to one end of the pressure plate facing the hexagonal end of the bolt. The plug can be inserted into the insertion hole opened in the square block.

[0010] Furthermore, the baffle has a through hole in the middle for bolts to pass through.

[0011] Furthermore, the lower end of the baffle is attached to the outer side of the pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the matching arrangement of notch, bolt, baffle and nut, can prevent rotation when installing bolt. It is only necessary to use a finger to hold the bolt in place so that it does not move out of the bolt hole, which facilitates the connection of pipes.

[0014] 2. This utility model, through the cooperative arrangement of the pressure plate, insert plate, insert rod, square block and insert hole, can enhance the strength of the notch and prevent the flange at the notch from deforming under stress. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1 to 5A pipe docking mechanism is used to dock two pipes 1. Each pipe 1 includes a flange 2, and the flange 2 has multiple bolt holes 3 in the shape of circular holes. The edge of the flange 2 has a notch 4 that communicates with the bolt holes 3. When docking the two pipes, a bolt 5 is inserted into the bolt holes 3. The outer side of the bolt 5 is fixedly connected to a positioning strip 6 that can be inserted into the notch 4 to position the bolt 5 and prevent the bolt 5 from rotating. Then, a baffle 7 is fitted on the other end of the bolt 5. The baffle 7 has a through hole 8 in the middle for the bolt 5 to pass through. After assembly, a nut 9 is threaded onto the bolt 5 at this end. After the nut 9 is tightened, the baffle 7 is pressed tightly against the flange 2, thereby docking the two pipes 1.

[0023] In this embodiment, it is passed.

[0024] Specifically, in order to prevent deformation of the notch 4 over a long period of time, a pressure plate 10 is fixedly connected to the upper end of the baffle 7 and attached to the outer side of the flange 2. The pressure plate 10 presses down the notch 4. In addition, an insert plate 11 that can be inserted into the notch 4 is fixedly connected to the lower end face of the pressure plate 10. That is, the positioning strip 6 and the insert plate 11 fill the notch 4, thereby further preventing the flange 2 of the notch 4 from deforming.

[0025] Specifically, in order to prevent the end of the pressure plate 10 away from the baffle 7 from tilting up, a square block 13 is fixedly connected to the upper end of the hexagonal end of the bolt 5, and a plug rod 12 is fixedly connected to the end of the pressure plate 10 facing the hexagonal end of the bolt 5. The plug rod 12 can be inserted into the insertion hole 14 opened in the square block 13. When installing the baffle 7, the plug rod 12 is aligned with the insertion hole 14.

[0026] Specifically, in order to ensure the stability of the baffle 7, the lower end of the baffle 7 is made to fit against the outer side of the pipe 1.

[0027] Installation method: First, fit the flanges 2 of the two pipes 1 together and align the bolt holes 3. Then, insert the bolt 5 so that the positioning strip 6 can be inserted into the notch 4. Then, put the baffle 7 on the threaded end of the bolt 5. After insertion, the insert plate 11 will be inserted into the notch 4 and the insert rod 12 will be inserted into the square block 13. Then, tighten the nut 9 on the bolt 5 to complete the connection of the two pipes 1.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. The scope of patent protection of this utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this utility model shall also be included within the scope of protection of this utility model.
