Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe splicing, in particular to a steel pipe splicing component which is easy to install and disassemble. Background Art

[0002] Steel pipes can be divided into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, etc. according to their uses. In the existing technology, steel pipes need to use splicing components to splice the corresponding connecting pipes together so that liquid or gas can flow between the two connecting pipes.

[0003] An existing steel pipe splicing structure (Announcement No.: CN220470891U) has at least the following disadvantages: the device connects two steel pipes by using a tough limit plate and a ratchet clamp. However, in actual application, if the two steel pipes are installed in a suspended manner, the connecting parts will bear the pressure transmitted by the deadweight of the steel pipes. This will cause the limit plate and ratchet that only use elastic clamping to become loose or even separate due to the large deadweight of the steel pipes, resulting in poor reliability of the connection. For this reason, the present utility model is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a steel pipe splicing assembly that is easy to install and disassemble.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] As a further solution of the present invention, a sealing seat is provided between the two fixing rings. The sealing seat is only fixed to the inside of the corresponding splicing seat. Sealing rings are fixed to the front and rear ends of the sealing seat, and the fixing rings are in close contact with the sealing rings.

[0008] As a further solution of the present invention, a number of locking holes are opened on the front sides of the four ends of the bottom of the abutment frame, and sliding seats are fixed on the left and right sides of the two splicing seats.

[0011] As a further solution of the present invention, a gripping rod is fixed to the top surface of the abutment frame.

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

[0013] By sleeve-fitting the splicing seat with the outer wall of the steel pipe and inserting the locking rod into the internal installation locking abutment frame of the locking hole, the bottom surface of the abutment frame abuts against the fixing ring to complete the connection of the steel pipe.

[0022] like Figures 1-4 As shown, a steel pipe splicing assembly that is easy to install and disassemble includes a fixing ring 101 fixed to the outer walls of two steel pipes 1, a splicing assembly is arranged between the two fixing rings 101, and the splicing assembly includes a splicing seat 2 arranged between the two fixing rings 101. The two splicing seats 2 are connected by a hinge, and the inner front side of the corresponding splicing seat 2 is provided with an inclined groove 201, and the inner rear side of the other splicing seat 2 is provided with an arc-shaped abutting portion 202. The front side of the corresponding fixing ring 101 is fixed with an inclined plate 203, the inclined plate 203 cooperates and abuts with the inclined groove 201, and the rear side of the other fixing ring 101 abuts with the arc-shaped abutting portion 202. The top surface of the fixing ring 101 is provided with an abutment frame 206, and the bottom surface of the abutment frame 206 is tightly abutted against the outer walls of the two fixing rings 101 respectively.

[0023] like Figure 2-Figure 4As shown, in this embodiment, a sealing seat 204 is provided between the two fixing rings 101, and the sealing seat 204 is only fixed to the inside of the corresponding splicing seat 2, and a sealing ring 205 is fixed to the front and rear ends of the sealing seat 204. The fixing ring 101 is in close contact with the sealing ring 205. By placing a steel pipe 1 in the interior of the corresponding splicing seat 2, the inclined plate 203 is matched with the inclined groove 201 to abut, thereby driving the fixing ring 101 to closely abut against the sealing seat 204. At this time, the other splicing seat 2 is rotated so that the other splicing seat 2 is sleeved with the outer wall of the other steel pipe 1. At this time, the arc-shaped abutting portion 202 on the splicing seat 2 is rotated with the splicing seat 2. The rotating abutting driving steel pipe 1 makes it tightly abut against the sealing seat 204. At this time, the abutting frame 206 is installed with the splicing seat 2 so that the bottom surface of the abutting frame 206 abuts against the fixing ring 101. Then, under the action of the two steel pipes 1's own weight, the two steel pipes 1 react on the two splicing seats 2 with the abutting frame 206 as the support point, so that the splicing seat 2 is subjected to a force in the relative rotation direction, thereby making the inclined plate 203 and the inclined groove 201, the arc-shaped abutting portion 202 and the fixing ring 101 more tightly abutted, and making the fixing ring 101 and the splicing seat 2 more tightly abutted, thereby ensuring the stability of the connection of the steel pipe 1 and the sealing effect.

[0024] like Figure 2-Figure 4 As shown, in this embodiment, a number of locking holes 3 are opened on the front sides of the four ends of the bottom of the abutment frame 206, and sliding seats 301 are fixed on the left and right sides of the two splicing seats 2. The internal sliding insertion of the sliding seat 301 is provided with a locking rod 302, and the locking rod 302 is inserted into the internal sliding of the corresponding locking hole 3.

[0025] like Figure 2-Figure 4 As shown, in this embodiment, a tension spring 303 is fixed to the end of the sliding seat 301 away from the locking hole 3, and the end of the tension spring 303 away from the sliding seat 301 is fixed to one side of the end of the locking rod 302. By setting the tension spring 303, the tension spring 303 can be used to restrain the locking rod 302, preventing the locking rod 302 from falling off from the inside of the locking hole 3, thereby increasing the reliability of the assembled component.

[0026] like Figure 2-Figure 4 As shown, in this embodiment, the left and right sides of the two splicing seats 2 are fixed with limiting frames 4, and the abutting frame 206 is slidably inserted between the limiting frames 4. By setting the limiting frames 4, the abutting frame 206 can be supported and limited.

[0027] like Figure 2-Figure 4 As shown, in this embodiment, a gripping rod 5 is fixed to the top surface of the abutting frame 206 , and the provision of the gripping rod 5 makes it easier for staff to change the frame and take the abutting frame 206 conveniently.

[0028] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: in use, by placing a steel pipe 1 inside the corresponding splicing seat 2, the inclined plate 203 is matched with the inclined groove 201 to abut, thereby driving the fixing ring 101 to closely abut against the sealing seat 204, and then rotating the other splicing seat 2 so that the other splicing seat 2 is sleeved with the outer wall of the other steel pipe 1. At this time, the arc-shaped abutting portion 202 on the splicing seat 2 abuts and drives the steel pipe 1 to closely abut against the sealing seat 204 as the splicing seat 2 rotates, and then the abutting frame 206 is taken out and inserted into the interior of the limiting frame 4 through the holding rod 5. At this time, the locking rod 302 is pulled during the process, driving the tension spring 303 to stretch, and then when the abutting frame When the bottom of 206 abuts against the outer wall of the fixing ring 101, the locking rod 302 is released, and the locking rod 302 is inserted into the corresponding locking hole 3 under the action of the rebound force of the tension spring 303, thereby locking the abutment frame 206. The connection of the steel pipe 1 can be completed by installing the abutment frame 206. After the connection, the two steel pipes 1 react on the two splicing seats 2 with the abutment frame 206 as the support point under the action of their own weight, so that the splicing seat 2 is subjected to the force in the relative rotation direction, so that the inclined plate 203 and the inclined groove 201, the arc-shaped abutment portion 202 and the fixing ring 101 are more tightly abutted, so that the fixing ring 101 and the splicing seat 2 are more tightly abutted, ensuring the stability and sealing effect of the connection of the steel pipe 1.
