Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection equipment technology, specifically a pipe fixing clamp. Background Technology

[0002] Traditional pipe clamps are typically designed as a single-level structure, meaning that a clamp of a specific size can only fit pipes of a fixed diameter. While this standardized design ensures good adaptability to specific pipe types and is particularly reliable in certain high-precision operating environments, it also brings obvious limitations and inconveniences, such as increased costs and storage management.

[0003] As the process of social industrialization continues to advance and the scale of engineering construction gradually expands, the demand for diversified equipment is increasing. The inability of traditional pipe clamps to meet the ever-changing actual needs has become an urgent problem to be solved. In response to the above situation, technological innovation is carried out on the basis of existing clamps. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe fixing clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe fixing clamp, comprising:

[0006] The first sealing disc and the second sealing disc each have a set of hexagonal grooves on opposite sides. A hexagonal truncated pyramid is set within each hexagonal groove. A multi-level groove is set on opposite sides of each of the two sets of hexagonal truncated pyramids. Positioning holes are evenly distributed on the outer walls of the hexagonal truncated pyramids, and magnetic blocks are embedded within these positioning holes. Threaded countersunk holes are evenly distributed on the outer walls of the first and second sealing discs. A receiving groove is formed between the threaded countersunk holes and the hexagonal grooves. A cross bolt is screwed into the threaded countersunk hole. A spring is fixedly installed on the outer wall of the cross bolt. A round-headed pin is fixedly installed on the outer wall of the spring. The round head of the round-headed pin is inserted into the positioning hole and magnetically attracted to the magnetic block.

[0007] Preferably, the spring is slidably disposed within the storage groove, and the cylindrical portion of the round-headed pin is slidably disposed within the storage groove.

[0008] Preferably, a first through hole is uniformly provided on the left side of the first sealing disc, and a second through hole is uniformly provided on the left side of the second sealing disc.

[0009] Preferably, the first through hole and the second through hole are aligned, and a bidirectional screw is provided in the first through hole and the second through hole.

[0010] Preferably, two sets of nuts are evenly screwed onto the outer side wall of the bidirectional screw, with the first sealing disc and the second sealing disc located between the two sets of nuts.

[0011] Preferably, the first sealing plate and the second sealing plate are distributed in a mirror image symmetrical arrangement, with the first sealing plate located to the left of the second sealing plate, and a set of grooves is provided on both the upper and lower sides of the inner wall of the multi-level groove.

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

[0013] This invention utilizes multi-level grooves on the outer side of the hexagonal frustum to allow it to be stably fitted onto a pipe with an inner diameter matching the grooves. This enables the device to clamp pipes of different sizes, and the hexagonal frustum can be directly pulled out of the hexagonal grooves via a pull groove. This allows for quick replacement of hexagonal frustums with multi-level grooves of different sizes, thereby further improving the adaptability of the device.

[0014] When the spring loses its elasticity due to prolonged use, or when the round-headed pin becomes damaged due to prolonged use, the cross bolt can be rotated to separate it from the threaded countersunk hole. At this point, the spring and round-headed pin can be pulled out of the storage slot through the cross bolt for replacement, thus ensuring the reliability of the device. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-3 A pipe fixing clamp includes a first sealing plate 1 and a second sealing plate 11. A set of hexagonal grooves is formed on opposite sides of both the first sealing plate 1 and the second sealing plate 11. A hexagonal truncated pyramid 2 is slidably disposed within each hexagonal groove. A set of multi-level grooves 21 is formed on opposite sides of both sets of hexagonal truncated pyramids 2. Positioning holes are evenly formed on the outer walls of the hexagonal truncated pyramids 2, and magnetic blocks 33 are embedded in the positioning holes. Threaded countersunk holes are evenly formed on the outer walls of the first sealing plate 1 and the second sealing plate 11. A receiving groove is formed between the threaded countersunk holes and the hexagonal grooves. A cross bolt 3 is screwed into the countersunk hole. A spring 31 is fixedly installed on the outer wall of the cross bolt 3. A round-headed pin 32 is fixedly installed on the outer wall of the spring 31. The round head of the pin 32 is inserted into the positioning hole and is magnetically attracted to the magnet 33. The spring 31 drives the pin 32 to be inserted into the positioning hole of the hexagonal truncated pyramid 2. The magnetic attraction of the magnet 33 to the pin 32 improves the insertion stability of the pin 32, thereby allowing the hexagonal truncated pyramid 2 to be stably fixed in the hexagonal groove. The spring 31 is slidably positioned in the storage compartment. Inside the groove, the cylindrical part of the round-headed pin 32 is slidably set in the storage groove. A first through hole is evenly opened through the left side of the first sealing plate 1, and a second through hole is evenly opened through the left side of the second sealing plate 11. The first through hole and the second through hole are aligned. A bidirectional screw 12 is rotatably installed in the first through hole and the second through hole. Two sets of nuts 13 are evenly screwed onto the outer wall of the bidirectional screw 12. The first sealing plate 1 and the second sealing plate 11 are located between the two sets of nuts 13. The first sealing plate 1 and the second sealing plate 11 are placed at both ends of the pipe. Then, the hexagonal frustums 2 inside the first sealing plate 1 and the second sealing plate 11 are respectively fitted onto the left and right ends of the pipe. Then, the two sets of nuts 13 are tightened. In this way, the first sealing plate 1 and the second sealing plate 11 can be squeezed inward by the two sets of nuts 13, thereby driving the two sets of hexagonal frustums 2 to clamp the two ends of the pipe. The first sealing plate 1 and the second sealing plate 11 are symmetrically distributed in a mirror image. The first sealing plate 1 is located to the left of the second sealing plate 11. A set of pull grooves 22 are opened on the upper and lower sides of the inner sidewall of the multi-level groove 21.

[0021] Working principle: Place the first sealing disc 1 and the second sealing disc 11 at both ends of the pipe. Then, fit the hexagonal frustum 2 inside the first sealing disc 1 and the second sealing disc 11 onto the left and right ends of the pipe, respectively. Then tighten the two sets of nuts 13. This allows the first sealing disc 1 and the second sealing disc 11 to press the pipe inward through the two sets of nuts 13, thereby driving the two sets of hexagonal frustum 2 to clamp the two ends of the pipe. It should be noted that the length of the double-ended screw 12 must exceed the total length of the first sealing disc 1 and the second sealing disc 11 after they are installed at both ends of the pipe. Through the multi-level grooves 21 opened on the outside of the hexagonal frustum 2, the hexagonal frustum 2 can be stably fitted onto the pipe that matches the inner diameter of the multi-level grooves 21. This allows the device to clamp pipes of different sizes. The round-headed pin 32 is inserted into the hexagonal frustum by the spring 31. The hexagonal truncated pyramid 2 is fixed in the hexagonal groove by the magnetic attraction of the round-headed pin 32 through the magnetic block 33. Since the hexagonal truncated pyramid 2 is fixed in the hexagonal groove by elasticity and magnetic force, it can be pulled out directly from the hexagonal groove by the pull groove 22. This allows for quick replacement of hexagonal truncated pyramid 2 with multi-level grooves 21 of different sizes, thereby further improving the adaptability of the device. When the spring 31 loses its elasticity due to long-term use, and the round-headed pin 32 is damaged due to long-term use, the cross bolt 3 is rotated to separate from the threaded countersunk hole. At this time, the spring 31 and the round-headed pin 32 can be pulled out from the storage groove for replacement through the cross bolt 3, thereby ensuring the reliability of the device.
