[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0016] A refrigeration pipe fixing device, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8As shown, it includes a base 1, a C-shaped bracket 2 is fixedly installed on the base 1, and the C-shaped bracket 2 is fixed to the base 1 through a column. The angle of the circle where the C-shaped bracket 2 is located is greater than 180° and less than 270°. In this embodiment, the angle of the circle where the C-shaped bracket 2 is located is 228°, and a coaxial semi-cylinder 3 is rotatably installed in the C-shaped bracket 2. The angle of the circle where the semi-cylinder 3 is located is the same as the angle of the circle where the C-shaped bracket 2 is located. The semi-cylinder 3 can rotate continuously in the C-shaped bracket 2, and several dovetail sliders 12 are fixedly installed on the semi-cylinder 3. Corresponding dovetail grooves 13 are provided on the C-shaped bracket 2. The dovetail sliders 12 are slidably installed in the corresponding dovetail grooves 13. A U-shaped groove 4 is provided on the semi-cylinder 3, and the arc circle of the U-shaped groove 4 is coaxially arranged with the semi-cylinder 3. A coaxial tooth groove 5 is provided on the outer periphery of the semi-cylinder 3, and the front and rear sides of the tooth groove 5 are respectively meshed with a first gear 6, and the tooth groove 5 will at least maintain meshing with one first gear 6. The first gear 6 is rotatably mounted on the support rod 7 through a one-way bearing. The inner ring of the one-way bearing is fixedly connected to the support rod 7. The outer ring of the one-way bearing is fixedly connected to the first gear 6. The support rod 7 is mounted on the base 1. Slide rods 8 are fixedly mounted on both sides of the base 1. Both ends of the slide rod 8 are fixedly connected to the base 1 through vertical rods. Sliders 9 are slidably mounted on the slide rod 8. Through holes are provided on the slide rod 9. The slide rod 8 slides in contact with the inner wall of the corresponding through hole. The bottom of the slide rod 9 slides in contact with the base 1 to prevent the slide rod 9 from rotating. The support rod 7 is fixedly connected to the slide rod 9. The slide rod 9 is elastically connected to the slide rod 8 through a first spring 10. The first spring 10 is mounted on the slide rod 8. One end of the first spring 10 is fixedly connected to the slide rod 8, and the other end of the first spring 10 is fixedly connected to the slide rod 9. Both sides of the base 1 are respectively connected to one end of the winding rope 11, and the other end of the winding rope 11 is connected to the corresponding side of the semi-cylinder 3. The present invention has a simple structure and an ingenious design. The pipeline is fixed by the winding rope 11, which avoids collisions between hard metal objects and is not easy to generate noise. The flexibility of the winding rope 11 can play a role in buffering and shock absorption, and can reduce the transmission of vibration, thereby reducing the spread of noise; the winding rope 11 can also be used to fix pipelines of different diameters, and has a wider range of applications; the winding rope 11 is spirally wound on the pipeline, and the clamping force of the winding rope 11 on the pipeline is more evenly distributed; when the pipeline is subjected to axial force, the winding rope 11 on one side will tighten, which can prevent the pipeline from continuing to move, can meet actual needs, and is suitable for promotion.When in use, the base 1 is installed in the desired position, and then the pipe is placed in the U-shaped groove 4, and then the semi-cylinder 3 is rotated. The semi-cylinder 3 rotates and pulls one end of the winding rope 11 on both sides to revolve around the pipe, and the other end of the winding rope 11 does not move, so that the winding rope 11 can be close to pipes of different sizes. The winding rope 11 is spirally wound on the pipe, and the winding directions of the winding ropes 11 on both sides are opposite until the winding rope 11 is completely wound around the pipe and the pipe is fixed; the winding directions of the winding ropes 11 on both sides are opposite. When the pipe is subjected to axial force, the pipe moves, and the winding rope 11 on one side becomes loose on the pipe, and the winding rope 11 on the other side becomes tighter due to the tension, thereby increasing the fixation of the pipe, thereby preventing it from continuing to move, and playing a role in buffering the axial force; the winding rope 11 is spirally wound on the pipe, and each turn of the winding rope 11 has a similar winding force on the pipe. , which can share the force more evenly; since the winding rope 11 is flexible, the contact between the winding rope 11 and the pipe is soft contact, which will not produce collision noise, is not conducive to the transmission of noise, and has lower noise; when the semi-cylinder 3 rotates, the first gear 6 rotates under the engagement with the tooth groove 5, and the first gear 6 can only rotate in one direction under the action of the one-way bearing, so that the rotated semi-cylinder 3 maintains its state and prevents it from resetting. When it is necessary to reset the semi-cylinder 3 to release the winding rope 11, the slider 9 is pushed and the first spring 10 is compressed, so that the slider 9 drives the first gear 6 to disengage from the tooth groove 5, so that the semi-cylinder 3 loses its restriction and can be rotated in the opposite direction to reset. After the semi-cylinder 3 is reset, the slider 9 is reset under the action of the first spring 10, and drives the first gear 6 to move until it is re-engaged with the tooth groove 5, and the semi-cylinder 3 can only rotate in one direction again.

[0017] Specifically, if Figure 1 、 Figure 8 As shown, support rods 20 are respectively installed at both ends of the semi-cylinder 3 described in this embodiment, and the two support rods 20 are symmetrically distributed on the left and right. A through groove 21 is provided on the support rod 20, and the winding rope 11 passes through the corresponding through groove 21. The winding rope 11 cannot move from the through groove 21. A limiting portion is provided at the other end of the winding rope 11, and a groove 22 is provided in the through groove 21. A pressure block 24 is installed in the groove 22 through several second springs 23. One end of the second spring 23 is fixedly connected to the inner wall of the groove 22, and the other end of the second spring 23 is fixedly connected to the pressure block 24. The pressure block 24 presses the corresponding winding rope 11. The semi-cylinder 3 drives the support rod 20 to rotate together, so that when the winding rope 11 is wound around the pipe, the winding rope 11 and the pressure block 24 slide and contact and cooperate. The pressure block 24 presses the winding rope 11 under the elastic force of the second spring 23. The winding rope 11 is subjected to a pre-tightening force, so that it fits more tightly with the pipe, and the winding rope 11 will not become loose. It is equivalent to a person tightening the winding rope 11 around the pipe by hand, which has a better winding effect and thus can more stably grasp the pipe.

[0018] Specifically, such as Figure 1 、 Figure 5、 Figure 7 As shown, in this embodiment, thread grooves are respectively provided on the support rod 20, and the screw rod 30 is installed with threaded cooperation. Circular slide grooves 31 communicating with the outside are respectively provided on both sides of the semi-cylinder 3, and the support rod 20 is slidably installed in the corresponding circular slide grooves 31. The support rod 20 can only slide in the circular slide grooves 31 and cannot rotate. Several guide blocks 32 are fixedly installed on the support rod 20, and corresponding guide slide grooves 33 are provided on the side walls of the circular slide grooves 31. The guide blocks 32 are slidably installed in the corresponding guide slide grooves 33. The screw rod 30 is rotatably installed in the circular slide grooves 31 through bearings. A coaxial second gear 34 is fixedly installed on the screw rod 30, and an arc rack 35 is meshed with one side of the second gear 34. The circle where the center of the two second gears 34 is located, the arc rack 35, and the semi-cylinder 3 are coaxially arranged. The arc rack 35 is fixedly installed on the C-shaped bracket 2, and an avoidance groove for avoiding the arc rack 35 is provided on the semi-cylinder 3. When the semi-cylinder 3 rotates forward, it drives the support rod 20 and the screw rod 30 to rotate together, so that the second gear 34 rotates when meshing with the arc-shaped rack 35, thereby driving the screw rod 30 to rotate. The rotation of the screw rod 30 causes the support rod 20 to slide in the direction of approaching each other, and the support rod 20 then drives the winding rope 11 to move, so that the winding rope 11 is more evenly wound on the pipe, so that the force on the winding rope 11 is more evenly applied, and it is avoided from piling up in one place; when the semi-cylinder 3 rotates reversely, the support rod 20 slides in the direction of moving away from each other.

[0019] Further, such as Figure 1 、 Figure 2 、 Figure 4 As shown, two U-shaped support plates 40 are fixedly mounted on the base 1 in this embodiment. The two U-shaped support plates 40 are symmetrically distributed on the left and right. The U-shaped support plates 40 are fixed to the base 1 via columns. The C-shaped bracket 2 is located between the two U-shaped support plates 40. Elastic rubber pads 41 are fixedly mounted on each of the U-shaped support plates 40. The elastic rubber pads 41 are also U-shaped. One end of the winding rope 11 is fixedly connected to the U-shaped support plates 40. The U-shaped support plates 40 provide support for the pipes. The elastic rubber pads 41 can prevent wear between the pipes and the U-shaped support plates 40 and also have a certain buffering effect, reducing the transmission of noise.

[0020] Furthermore, if Figure 2 As shown, the base 1 of this embodiment is fixed with a plurality of mounting holes 50, which are countersunk holes. The mounting holes 50 are used to conveniently fix the device at a desired position.

[0021] Furthermore, if Figure 2 、 Figure 6 As shown, in this embodiment, several handles 60 are fixedly mounted on the semi-cylinder 3. Rotating the semi-cylinder 3 by the handles 60 is more convenient and labor-saving.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
