Description

Technical Field

[0001] This utility model relates to the field of pipe opening technology, specifically a universal angle clamp for opening pipe sidewalls. Background Technology

[0002] Pipeline sidewall drilling is a process of creating holes in the side of a pipeline during operation, based on actual needs. This technology is widely used in industrial pipeline modification, pipeline maintenance, and pipeline branch connections. Currently, some pipelines require clamps to secure them before drilling holes for installation.

[0003] However, while existing clamps are relatively simple to fix pipes, it is inconvenient to disassemble and replace the clamps with clamps that are suitable for pipes when fixing pipes of different sizes. Direct clamping will result in a small contact area between the clamp and the pipe, affecting the stability of the pipe when drilling, thus reducing the applicability of the clamp.

[0004] Meanwhile, some existing clamps are inconvenient to control the angle of the pipe during use. After drilling one hole in the pipe, it is not convenient and cumbersome to drill a second hole. It is impossible to accurately control the angle between the two holes, which not only affects the drilling efficiency of the pipe, but also reduces the convenience of the device. Utility Model Content

[0005] The purpose of this invention is to provide a universal angle clamp for opening holes in the sidewalls of pipes, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a universal angle clamp for opening holes in the sidewall of a pipe, comprising a base and mounting brackets fixed at two points on its top, and further comprising:

[0007] A rotating ring rotates within the inner cavity of the mounting frame. A fixed frame is fixedly connected to one side of the rotating ring. A locking hoop is slidably connected to the inner cavity of the fixed frame. Movable frames are slidably connected to both the upper and lower parts of the inner cavity of the fixed frame. A positioning rod is fixedly connected to the surface of the movable frame.

[0008] A positioning hole is provided on the surface of the locking ring; an adjustment mechanism is installed on the surface of the fixing frame; a fixing mechanism is installed on the surface of the mounting frame; an angle line is provided on one side of the rotating ring; and a pointer is fixedly connected to the surface of the mounting frame.

[0009] Preferably, the adjustment mechanism includes a movable frame that slides on the inner wall of the movable frame, with movable blocks fixedly connected to the top and bottom of the movable frame, and a return spring fixedly connected to the top of the movable frame.

[0010] Preferably, the fixing mechanism includes a threaded rod threaded to the inner wall of the mounting bracket and an extrusion plate rotating at its bottom, with a rubber block fixedly connected to the bottom of the extrusion plate.

[0011] Preferably, one side of the movable block and one side of the inner cavity of the movable frame are both designed with an inclined structure, and the surface of the movable block is slidably connected to the inner wall of the movable frame.

[0012] Preferably, a rubber ring is fixedly connected to the surface of the rotating ring, and the rubber ring is used in conjunction with the rubber block.

[0013] Preferably, one side of the fixing frame is slidably connected to one side of the mounting frame, and the cross-sectional shape of the rotating ring is an L-shaped structure design.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention, through the cooperation of the adjustment mechanism, movable frame, and positioning rod, facilitates the replacement of locking clamps by operators. This allows the device to select the appropriate locking clamp according to the pipe size, which is not only convenient but also improves pipe stability and effectively enhances the applicability of the clamp. Furthermore, the coordination of the angle line and pointer facilitates the adjustment of the pipe angle by the rotating ring.

Detailed Implementation

[0022] 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.

[0023] Please see Figures 1-5As shown, a universal angle clamp for drilling holes in the sidewall of a pipe includes a base 1. Mounting brackets 2 are fixedly connected to two points on the top of the base 1. A rotating ring 3 is rotatably connected to the inner cavity of the mounting bracket 2. A fixing bracket 4 is fixedly connected to one side of the rotating ring 3. One side of the fixing bracket 4 is slidably connected to one side of the mounting bracket 2. The rotating ring 3 has an L-shaped cross-section. Under this design, the fixing bracket 4 and the rotating ring 3 can cooperate to prevent significant positional displacement within the mounting bracket 2 during rotation, thus ensuring greater stability of the rotating ring 3 and preventing insufficient rotation from affecting the pipe's fixing effect. A locking clamp 5 is slidably connected to the inner cavity of the fixing bracket 4. The locking clamp 5 can limit the pipe's movement, facilitating subsequent drilling. Movable brackets 6 are slidably connected to the upper and lower parts of the inner cavity of the fixing bracket 4. A positioning rod 7 is fixedly connected to the surface of the movable bracket 6. A positioning hole 8 is formed on the surface of the locking clamp 5. The inner wall of the positioning hole 8 is slidably connected to the surface of the positioning rod 7. The surface of the frame 4 is equipped with an adjustment mechanism 9. This mechanism allows the movable frame 6 to move the positioning rod 7, facilitating the insertion or removal of the positioning rod 7 into or from the positioning hole 8. This also facilitates the replacement of the locking clamp 5, enabling the clamp to easily fix pipes of different sizes and effectively improving its applicability. The surface of the mounting frame 2 is equipped with a fixing mechanism 10, which secures the rotating ring 3, preventing it from rotating unnecessarily and improving its stability. An angle line 11 is provided on one side of the rotating ring 3, and a pointer 12 is fixedly connected to the surface of the mounting frame 2. The pointer 12 works in conjunction with the angle line 11. When the pipe angle needs adjustment, the rotating ring 3 can be rotated directly to change the pipe angle. The angle line 11 and pointer 12 accurately indicate the pipe's rotation angle, facilitating pipe drilling and further enhancing the device's applicability.

[0024] The adjusting mechanism 9 includes a movable frame 91 that slides on the inner wall of the movable frame 6. Movable blocks 92 are fixedly connected to the bottom and top of the movable frame 91. One side of the movable block 92 and one side of the inner cavity of the movable frame 6 are both inclined. The surface of the movable block 92 is slidably connected to the inner wall of the movable frame 6. Under this action, the movable frame 91 can move the movable block 92 and squeeze the movable frame 6, thereby enabling it to move the positioning rod 7 out of the positioning hole 8, thus facilitating the release of the locking clamp 5. Under the action of the shape of the movable frame 91, the two movable frames 6 can be adjusted, effectively improving the applicability of the clamp. A return spring 93 is fixedly connected to the top of the movable frame 6. The other end of the return spring 93 is fixedly connected to the inner wall of the fixed frame 4. Under this action, the movable frame 6 can return to its original position when it is not squeezed, so that the positioning rod 7 can be embedded in the positioning hole 8.

[0025] The fixing mechanism 10 includes a threaded rod 101 threaded to the inner wall of the mounting bracket 2. A pressing plate 102 is rotatably connected to the bottom of the threaded rod 101. A rubber block 103 is fixedly connected to the bottom of the pressing plate 102. Under this action, the pressing plate 102 can drive the rubber block 103 to press the surface of the rotating ring 3 through the cooperation of the threaded rod 101, so that the rotating ring 3 will not easily rotate, thus facilitating the fixing of the rotating ring 3 and preventing it from moving arbitrarily after the angle is adjusted. The surface of the pressing plate 102 is slidably connected to the inner wall of the mounting bracket 2. Under this action, the pressing plate 102 will not rotate arbitrarily and affect the contact area between it and the rotating ring 3. A rubber ring 13 is fixedly connected to the surface of the rotating ring 3. The rubber ring 13 and the rubber block 103 are used in conjunction. Under this action, the friction between the rubber ring 13 and the rubber block 103 is increased by the action of the material, thereby improving the stability of the rotating ring 3.

[0026] It is worth noting that the technical features such as the locking clamp 5 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0027] Working principle: First, when the locking clamp 5 needs to be replaced, the operator pulls the moving frame 91, causing the movable block 92 to press against the moving frame 6, thereby moving the positioning rod 7 out of the positioning hole 8. Then, the locking clamp 5 is removed, and a locking clamp 5 of the appropriate size for the pipe is installed. After the moving frame 91 is reset, the positioning rod 7 can be inserted into the positioning hole 8 with the help of the return spring 93, thereby fixing the locking clamp 5. This makes it convenient for the clamp to limit the pipes of different sizes, effectively improving the applicability of the clamp. After the pipe is fixed by the locking clamp 5, the rotating ring 3 is rotated to adjust the angle of the pipe, effectively improving the applicability of the clamp. After the rotating ring 3 is adjusted by the cooperation of the pointer 12 and the angle line 11, the operator rotates the threaded rod 101 so that the extrusion plate 102 contacts the rubber ring 13 through the rubber block 103, thereby limiting the rotating ring 3. Then, the pipe can be drilled.
