Description

Technical Field

[0001] This utility model relates to the field of internal and external thread elbow technology, specifically an internal and external thread elbow that can be fixed in position. Background Technology

[0002] Pipe fittings are essential transmission elements in the process of gas and liquid transportation. They are usually interconnected by pipes, elbows, tees or stiles. In the traditional construction process, straight pipes are installed first, and elbows are added where bends are needed to change the direction of the pipes. The "internal thread" of the internal thread elbow refers to the part that connects to the pipe or fitting, and its thread is located on the inside of the elbow. The "external thread" refers to the part that mates with the pipe or fitting, and its thread is located on the outside of the elbow.

[0003] In existing technologies, elbows are usually installed near the roof to meet the needs of pipe turning; however, traditional elbows are often directly connected to the pipe without a position fixing mechanism. This direct connection may lead to insufficient elbow stability, and the pipe may tilt due to its own weight. Therefore, it is necessary to propose a fixed-position internal and external thread elbow to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed-position internal and external thread elbow, which facilitates the fixation of the internal and external thread elbow body, improves its stability in use, and thus prevents the pipeline from tilting.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-position internal and external thread elbow, comprising an internal and external thread elbow body, a fixing seat fixedly connected to the front side of the outer wall of the internal and external thread elbow body, a rectangular groove extending through the upper end of the fixing seat, a sliding groove extending through the rear side of the inner wall of the rectangular groove, a sliding rail extending to the outer side of the sliding groove being slidably connected inside the sliding groove, an adjusting plate fixedly connected to the front end of the sliding rail, an mounting plate fixedly connected to the upper end of the adjusting plate, and a plurality of mounting holes extending through the outer wall of the mounting plate;

[0006] A fastening nut is fixedly connected through the front side of the inner wall of the fixed seat. The fastening nut is internally threaded with a fastening screw extending to its outer side. A pressure plate is provided inside the rectangular groove. A turntable fixedly connected to the fastening screw is provided at the front end of the pressure plate. A torsion block is fixedly connected to the front end of the fastening screw.

[0007] In order to improve the anti-slip effect when the pressure plate and the adjusting plate are in close contact, and to further improve the fixing effect on the position of the internal and external thread elbow body, as a preferred embodiment of the present invention for a fixed-position internal and external thread elbow, an anti-slip layer is provided on the opposite side of the pressure plate and the adjusting plate.

[0008] To improve the stability of the pressure plate movement, in a preferred embodiment of this utility model of a fixed-position internal and external threaded elbow, the pressure plate is fitted to the left and right sides of the inner wall of the rectangular groove.

[0009] To facilitate applying torque to the twist block using a wrench, the cross-section of the twist block is preferably a regular hexagonal structure, which is a preferred type of internal and external threaded elbow that can be fixed in position according to this utility model.

[0010] To improve the stability of the turntable rotation, as a preferred embodiment of the fixed-position internal and external thread elbow of this utility model, the front end of the pressure plate is provided with an annular groove, and an annular block that is fixedly connected to the turntable is slidably connected inside the annular groove.

[0011] To prevent the slide rail from detaching from the inside of the slide groove, the slide groove and the slide rail are preferably matched dovetail structures, which is a preferred type of fixed-position internal and external thread elbow of this utility model.

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

[0013] Connect two pipes to the body of the internal and external threaded elbow, then push the adjusting plate and the mounting plate upwards so that the mounting plate abuts against the roof. Then, use fasteners and multiple mounting holes to connect and fix the mounting plate to the roof. This method can adapt to pipe installation in different positions. The horizontal position of the internal and external threaded elbow body is limited by the slide rail and slide groove. Then, when the torsion block is rotated, the pressure plate can be moved backwards and abut against the adjusting plate. Then, by forcefully twisting the torsion block with a wrench, the pressure plate and the adjusting plate can be brought into a tight abutment state, thereby completing the fixation of the position of the internal and external threaded elbow body. This further facilitates the fixation of the position of the internal and external threaded elbow body, improves its stability in use, and prevents the pipeline from tilting.

[0021] Please see Figures 1 to 4 A fixed-position internal and external thread elbow includes an internal and external thread elbow body 1. A fixing seat 2 is fixedly connected to the front side of the outer wall of the internal and external thread elbow body 1. A rectangular groove 3 is opened through the upper end of the fixing seat 2. A sliding groove 4 is opened through the rear side of the inner wall of the rectangular groove 3. A sliding rail 5 extending to the outer side is slidably connected inside the sliding groove 4. An adjusting plate 6 is fixedly connected to the front end of the sliding rail 5. An mounting plate 12 is fixedly connected to the upper end of the adjusting plate 6. A plurality of mounting holes 13 are opened through the outer wall of the mounting plate 12.

[0022] A fastening nut 7 is fixedly connected through the front side of the inner wall of the fixed base 2. The fastening nut 7 is internally threaded with a fastening screw 8 extending to its outer side. A pressure plate 11 is provided inside the rectangular groove 3. A turntable 10 is fixedly connected to the front end of the pressure plate 11 and the fastening screw 8. A torsion block 9 is fixedly connected to the front end of the fastening screw 8.

[0023] In this embodiment: During use, first connect two pipes to the inner and outer threaded elbow body 1. At this time, the inner and outer threaded elbow body 1 is positioned near the roof. Then, push the adjusting plate 6 upwards along the slide rail 5, thereby moving the mounting plate 12 upwards until the mounting plate 12 abuts against the roof. Due to the multiple mounting holes 13, the mounting plate 12 can be fixed to the roof using fasteners. Since the position of the mounting plate 12 is freely adjustable, it can adapt to pipe installations in different locations. The design of the slide rail 5 and the groove 4 allows for adjustment of the inner and outer threaded elbow body. The elbow body 1 is positioned horizontally. Then, the torsion block 9 is rotated, which in turn drives the fastening screw 8 and the turntable 10 to rotate, thereby moving the pressure plate 11 backward until the pressure plate 11 abuts against the adjusting plate 6. Then, the torsion block 9 is twisted forcefully with a wrench, so that the pressure plate 11 and the adjusting plate 6 are in a tight abutment state. This prevents the fixed seat 2 and the internal and external thread elbow body 1 from moving up and down, further facilitating the fixation of the internal and external thread elbow body 1, improving its stability in use, and thus preventing the pipeline from tilting.

[0024] As a technical optimization of this utility model, the pressure plate 11 and the adjusting plate 6 are both provided with anti-slip layers on the opposite side.

[0025] In this embodiment, by setting an anti-slip layer, the anti-slip effect is improved when the pressure plate 11 and the adjusting plate 6 are in close contact, thereby further improving the fixing effect on the position of the inner and outer thread elbow body 1.

[0026] As a technical optimization of this utility model, the pressure plate 11 is attached to the left and right sides of the inner wall of the rectangular groove 3.

[0027] In this embodiment, since the pressure plate 11 is attached to the left and right sides of the inner wall of the rectangular groove 3, the stability of the movement of the pressure plate 11 is improved.

[0028] As a technical optimization of this utility model, the cross-section of the twist block 9 is a regular hexagonal structure.

[0029] In this embodiment: Since the cross-section of the torsion block 9 is a regular hexagonal structure, it is convenient to apply torque to the torsion block 9 with a wrench.

[0030] As a technical optimization of this utility model, the front end of the pressure plate 11 is provided with an annular groove, and an annular block that is fixedly connected to the turntable 10 is slidably connected inside the annular groove.

[0031] In this embodiment, the stability of the turntable 10 rotation is improved by setting an annular groove and an annular block.

[0032] As a technical optimization of this utility model, the slide groove 4 and the slide rail 5 are dovetail-shaped structures that match each other.

[0033] In this embodiment, since the slide groove 4 and the slide rail 5 are mutually matched dovetail structures, the slide rail 5 can be prevented from detaching from the inside of the slide groove 4.

[0034] Working principle: In use, first connect the two pipes to the body 1 of the internal and external threaded elbow. At this time, the body 1 of the internal and external threaded elbow is located near the roof. Then, push the adjusting plate 6 to move upward with the slide rail 5, which in turn drives the mounting plate 12 to move upward until the mounting plate 12 abuts against the roof. Due to the setting of multiple mounting holes 13, the mounting plate 12 can be connected and fixed to the roof with fasteners. Since the position of the mounting plate 12 can be freely adjusted, it can adapt to the installation of pipes in different positions. At this time, the design of the slide rail 5 and the slide groove 4 can adjust the internal and external threaded elbow. The horizontal position of the head body 1 is limited, and then the torsion block 9 is rotated, which in turn drives the fastening screw 8 and the turntable 10 to rotate, thereby driving the pressure plate 11 to move backward until the pressure plate 11 abuts against the adjusting plate 6. Then, by forcefully twisting the torsion block 9 with a wrench, the pressure plate 11 and the adjusting plate 6 can be brought into a tight abutment state, thereby preventing the fixed seat 2 and the internal and external thread elbow body 1 from moving up and down, further facilitating the position fixation of the internal and external thread elbow body 1, improving its stability in use, and thus preventing the pipeline from tilting.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
