Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a connection structure and a 150-degree elbow. Background Art

[0002] In pipeline engineering, an elbow is a pipe connector used to change the flow direction or angle of the pipeline. It is usually made of a bent pipe and can be a right-angle elbow, a 45-degree elbow, a 90-degree elbow, or even a 150-degree elbow. When it is connected to other pipes, in order to improve the firmness of its installation, the traditional method is to weld the connecting pipe and the 150-degree elbow together for subsequent transportation and use.

[0003] In the prior art, workers usually need to use welding equipment to weld the traditional 150-degree elbow to the connecting pipe during installation to ensure a firm connection. However, this method is more complicated when disassembly is required, and cutting tools are required to separate the welded parts. The existing elbow is generally connected to the connecting pipe through a flange, and the two flanges are fastened together with fixing bolts. However, workers need to use tools during disassembly and assembly, which makes the disassembly and assembly process complicated, inconvenient for workers to operate, and also affects work efficiency.

[0004] Therefore, a connection structure and a 150-degree elbow are needed to solve the problem that workers need to use tools when disassembling and assembling the existing elbow, which makes the disassembly and assembly process more complicated, thereby affecting work efficiency.

[0028] First, insert the connecting pipe 2 into the front end of the elbow body 1 along the four protrusions on its rear side, and let the front end of the elbow body 1 fit against the inner wall of the connecting pipe 2. Then, install the lower clamp 5 at the bottom of the connection between the connecting pipe 2 and the elbow body 1. Then, install the upper clamp 4 downward on the top of the connecting pipe 2 and the elbow body 1, and let the plug-in block 6 be plugged into the inner wall of the slot 7, thereby completing the connection between the elbow body 1 and the connecting pipe 2, which is convenient for workers to use.

[0029] Embodiment 2

[0030] On the basis of Example 1, in order to realize the clamping connection between the upper clamping plate 4 and the lower clamping plate 5, a slide groove 13 is provided on the left and right sides of the lower clamping plate 5, and a card block 11 is slidably connected to the inner wall of the slide groove 13. A plurality of springs 12 are installed on the separated sides of the left and right card blocks 11, so that the elastic force of the springs 12 is used to drive the card block 11 to be inserted into the inner wall of the second slot 15, and two buttons 8 are inserted on the left and right sides of the lower clamping plate 5. The bottom of the two plug-in blocks 6 is provided with a second slot 15; the sides of the buttons 8 on the front and rear sides are close to the card block 11, so as to facilitate the card block 11 to slide along the inner wall of the slide groove 13 and let it disengage from the second slot 15, and the separated ends of the left and right springs 12 are installed on the inner wall of the slide groove 13, and the sides of the left and right card blocks 11 are close to each other and inserted into the inner wall of the second slot 15.

[0031] During installation, the plug-in block 6 will be driven to be plugged into the inner wall of slot one 7. At this time, since the top of the side close to the two card blocks 11 is an arc surface, when the plug-in block 6 is plugged downward into the inner wall of slot one 7, the card block 11 will be driven to slide on the inner wall of the slide groove 13 and squeeze the spring 12. When the plug-in block 6 is fully installed in place, the elastic force of the spring 12 drives the card block 11 to be plugged into the inner wall of slot two 15, thereby facilitating the installation of the elbow body 1 and the connecting pipe 2. When disassembly is required, first press the two buttons 8 to drive the card block 11 to slide along the inner wall of the slide groove 13, thereby driving the card block 11 out of slot two 15. At this time, the worker pulls the upper splint 4 upward to allow the plug-in block 6 to be out of slot one 7, thereby facilitating the worker to disassemble the elbow body 1 and the connecting pipe 2, thereby improving the worker's disassembly and assembly efficiency.

[0032] Embodiment 3

[0033] On the basis of Example 2, in order to improve the sealing between the connecting pipe 2 and the elbow body 1, one of the sealing rings 3 is installed on the front outer side of the elbow body 1, and another sealing ring 3 is installed on the rear outer side of the connecting pipe 2. Two of the mounting grooves 9 are opened on the inner wall of the upper clamp plate 4, and the other two mounting grooves 9 are opened on the inner wall of the lower clamp plate 5; the front sealing ring 3 is installed on the inner walls of the two front mounting grooves 9, and the rear sealing ring 3 is installed on the inner walls of the two rear mounting grooves 9, so that the two sealing rings 3 are inserted into the inner walls of the mounting grooves 9 through the cooperation between the upper clamp plate 4 and the lower clamp plate 5, thereby improving the sealing between the connecting pipe 2 and the elbow body 1.

[0034] During installation, since sealing rings 3 are provided on the outer sides of the elbow body 1 and the connecting pipe 2, and the front sealing ring 3 is installed on the inner walls of the two front installation grooves 9, and the rear sealing ring 3 is installed on the inner walls of the two rear installation grooves 9, when the upper clamp plate 4 and the lower clamp plate 5 are installed and closed, the sealing between the connecting pipe 2 and the elbow body 1 is increased, thereby improving its use effect.

[0035] Embodiment 4

[0036] On the basis of Example 3, in order to improve the installation firmness between the upper clamp plate 4 and the lower clamp plate 5, clamping columns 10 are installed on both sides of the bottom of the upper clamp plate 4, and clamping grooves 14 are opened on both sides of the top of the lower clamp plate 5, and the clamping columns 10 are inserted into the inner wall of the clamping groove 14.

[0037] During installation, since the upper clamp plate 4 needs to cooperate with the lower clamp plate 5 to install the elbow body 1 and the connecting pipe 2 together, at this time, when the upper clamp plate 4 is installed downward, it will drive the two clamping columns 10 at its bottom to be inserted into the inner walls of the two clamping grooves 14 at the top of the lower clamp plate 5, thereby making the installation between the upper clamp plate 4 and the lower clamp plate 5 more secure, thereby improving the firmness of the installation between the elbow body 1 and the connecting pipe 2.
