[0010] Preferably, a pull ring is fixedly connected to the end of the strap away from the positioning tube, and the pull ring is an iron ring.

[0011] The effect achieved by the above components is that the operating pull ring tightens the strap, making it convenient for the user to move the strap.

[0012] Preferably, a plurality of protrusions are fixedly connected to the side of the clamp away from the adjusting rod, and the protrusions are in the shape of a pointed cone.

[0013] The effect achieved by the above components is to increase the friction on the surface of the clamp plate by the protrusions, so that the clamp plate can better limit the strap.

[0014] Preferably, a slide rod is fixedly connected to the side of the clamping plate near the adjusting rod, and the arc surface of the slide rod is slidably connected to the adjusting frame.

[0015] The effect achieved by the above components is to further limit the clamping plate by means of the slide bar, so that the clamping plate is more stable when moving along the adjustment frame.

[0017] The effect achieved by the above-mentioned components is to increase the friction at the lower end of the adjusting rod through the anti-slip protrusions, making it easier for the user to rotate the adjusting rod.

[0018] Preferably, the strap is a polyester strap.

[0019] The above components achieve the following effects: the straps are made of polyester, which has the advantages of corrosion resistance, good stability, and long service life.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] In this invention, by setting an adjustment structure, the operating strap is placed in a designated position, and the clamp and adjustment frame are used to tighten and limit the strap, thereby fixing the machine body in the designated position. No drilling is required, reducing the difficulty of installation. The strap is suitable for non-planar structures that are difficult to install using traditional methods, such as circular pipes, I-beams, and guardrails. It can improve installation flexibility and work efficiency, and can be quickly deployed for real-time monitoring. The positioning tube on the strap cooperates with the stop bar to make it easy to detach and install the strap from the mounting frame, making it convenient for users to replace and maintain the strap, thus improving its practicality.

[0028] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a refrigerant leakage monitoring device for refrigeration equipment, including a body 1, a display screen 2 installed on the surface of the body 1, a gas sensor 3 installed at the lower end of the body 1, an electrical interface 4 provided at one end of the body 1, an alarm light 5 installed at the end of the body 1 away from the electrical interface 4, and an adjustment structure 6 provided on the side of the body 1 away from the display screen 2.

[0030] The specific settings and functions of its adjustment structure 6 will be explained in detail below.

[0031] Reference Figures 2 to 5As shown in this embodiment: the adjustment structure 6 includes a mounting bracket 601, which is fixedly connected to the body 1. Several mounting feet 602 are fixedly connected to the four sides of the mounting bracket 601. A strap 603 is slidably connected to the inner wall of the mounting bracket 601. A positioning tube 604 is fixedly connected to one end of the strap 603. A fixing frame 605 is slidably connected to the arc surface of the positioning tube 604. The upper surface of the fixing frame 605 is fixedly connected to the mounting bracket 601. Stop bars 606 are threaded into both ends of the positioning tube 604. The lower surface of the mounting bracket 601 is fixedly connected to... An adjusting frame 609 is attached, with its inner wall slidably connected to the strap 603. An adjusting rod 610 is threadedly inserted into the lower surface of the adjusting frame 609, and a clamping plate 611 is rotatably connected to the upper end of the adjusting rod 610. The clamping plate 611 is slidably connected to the inner wall of the adjusting frame 609. The machine body 1 is fixed in a designated position using the easily tightenable strap 603, reducing the difficulty of installation and improving installation flexibility. An anti-slip pad 607, which is a rubber pad, is fixedly attached to the surface of the strap 603 to increase the friction of the strap 603 surface. The strap 603 is rubbed to stabilize its binding effect. A pull ring 608, made of iron, is fixedly connected to the end of the strap 603 furthest from the positioning tube 604. Operating the pull ring 608 tightens the strap 603, facilitating user movement. Several protrusions 612, cone-shaped, are fixedly connected to the side of the clamp 611 furthest from the adjusting rod 610. These protrusions increase the friction on the surface of the clamp 611, improving its limiting effect on the strap 603. A sliding mechanism is fixedly connected to the side of the clamp 611 closest to the adjusting rod 610. The arc surface of the rod 613 is slidably connected to the adjusting frame 609. The sliding rod 613 further limits the clamping plate 611, making the clamping plate 611 more stable when moving along the adjusting frame 609. Several anti-slip protrusions are fixedly connected to the lower end of the adjusting rod 610. The anti-slip protrusions are evenly distributed on the adjusting rod 610. The anti-slip protrusions increase the friction at the lower end of the adjusting rod 610, making it easier for the user to rotate the adjusting rod 610. The strap 603 is made of polyester, which has the advantages of corrosion resistance, good stability and long service life.

[0032] Detailed Instructions for Use: By setting the adjustment structure 6, pull the strap 603. The strap 603 moves the two stop rods 606 through the positioning tube 604 until the two stop rods 606 are blocked. Operate the end of the strap 603 away from the positioning tube 604 so that the strap 603 is placed on the crossbeam at the designated position. Continue to operate the strap 603 through the adjustment frame 609, then tighten the strap 603. Rotate the adjustment rod 610. The adjustment rod 610 moves the clamping plate 611 closer to the strap 603 through the thread. Continue to rotate the adjustment rod 610 until the clamping plate 611, in conjunction with the inner wall of the adjustment frame 609, clamps and fixes the strap 603. Before installation, if the strap 603 needs to be replaced, first rotate the stop rods 606 at both ends of the positioning tube 604. The stop rods 606 slide away from the positioning tube 604 through the thread. At this time, the strap 603 and the positioning tube 604 can be pulled out. Remove the fixed frame 605 and mounting bracket 601, then take a new strap 603. Move the strap 603 and positioning tube 604 into the mounting bracket 601 until the fixed frame 605 is in position, and then screw on the stop bar 606. The anti-slip pad 607 increases the friction on the surface of the strap 603, making the binding effect of the strap 603 more stable. The operating pull ring 608 drives the strap 603 to tighten, making it easier for the user to move the strap 603. The protrusion 612 increases the friction on the surface of the clamping plate 611, making the clamping plate 611 better limit the strap 603. The slide bar 613 further limits the clamping plate 611, making the clamping plate 611 more stable when moving along the adjusting frame 609. The anti-slip protrusion increases the friction at the lower end of the adjusting rod 610, making it easier for the user to rotate the adjusting rod 610. The strap 603 is made of polyester tape, which has the advantages of corrosion resistance, good stability and long service life.
