[0002] With the continuous development of refrigeration technology, refrigeration units have been widely used in industrial production and daily life. Piping connections play a crucial role in the operation of refrigeration units. However, existing piping connection components for refrigeration units currently have some problems in practical applications.

[0003] Typically, refrigeration units are connected via flexible pipes to the unit's inlets through end flanges. While this connection method meets the equipment's operational requirements to some extent, in practice, it has been found that pipes and inlets are prone to detachment under pressure. This not only affects the normal operation of the refrigeration unit but may also lead to refrigerant leaks, posing a safety hazard to equipment and personnel.

[0004] Therefore, a pipe connection assembly for a refrigeration unit is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe connection assembly for a refrigeration unit in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A pipe connection assembly for a refrigeration unit includes a refrigeration unit body and a pipe opening disposed on the surface of the refrigeration unit body. A horizontal plate is fixedly installed on the surface of the refrigeration unit body and corresponding to the pipe opening. A fastening assembly is disposed on the horizontal plate. A pressure-applying assembly is inserted into the movable part of the horizontal plate and the fastening assembly. A strap is fixedly installed on the movable part of the fastening assembly.

[0008] Furthermore, the fastening assembly includes a threaded rod that is movably inserted into the cross plate, and a knob is fixedly installed at the top of the threaded rod. An internal threaded sleeve is threaded onto the surface of the threaded rod, and a pull plate is fixedly fitted onto the surface of the internal threaded sleeve. The two ends of the strap are respectively fixedly installed on the bottom surface of the pull plate.

[0009] Furthermore, the pressure application component includes a guide rod that is movably inserted into the horizontal plate and the pull plate, and an arc-shaped pressure plate is fixedly installed at the bottom end of the guide rod. The surface of the arc-shaped pressure plate is provided with a pressure strip, and through holes are opened on the arc-shaped pressure plate and the pressure strip, and the strap is movably inserted into the through holes.

[0010] Furthermore, a sealing groove is provided on the surface of the pipe opening, wherein during pipe installation, the pipe is fitted onto the surface of the pipe opening and the flange at its end is fixedly connected to the large flange on the surface of the pipe opening.

[0011] Furthermore, the arc-shaped pressure plate is located above the sealing groove on the surface of the pipe opening, and the bottom end of the threaded rod is in contact with the top surface of the arc-shaped pressure plate.

[0012] Furthermore, the pressure strips and binding straps on the inner wall of the arc-shaped pressure plate are fitted to the surface of the pipe and are correspondingly arranged with the sealing groove on the surface of the pipe opening.

[0013] The beneficial effects of this utility model are as follows:

[0014] When pipes need to be connected, the pipe is fitted onto the pipe opening surface, and the flange at the end of the pipe is fixed to the flange on the pipe opening surface. Through the fastening components, the pipe is securely connected to the pipe opening on the surface of the refrigeration unit body by the cooperation of the binding strap and the pressure application components, which prevents the pipe from falling off the pipe opening under pressure and ensures the stability of the connection.

[0025] like Figures 1 to 5 As shown, a pipe connection assembly for a refrigeration unit includes a refrigeration unit body 1 and a pipe opening 2 disposed on the surface of the refrigeration unit body 1. A horizontal plate 3 is fixedly installed on the surface of the refrigeration unit body 1 corresponding to the pipe opening 2, and a fastening assembly 4 is disposed on the horizontal plate 3; as shown Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, specifically, the fastening assembly 4 includes a threaded rod 401 that is movably inserted into the horizontal plate 3, and a knob 402 is fixedly installed at the top of the threaded rod 401. An inner threaded sleeve 403 is threadedly fitted on the surface of the threaded rod 401, and a pull plate 404 is fixedly fitted on the surface of the inner threaded sleeve 403. The two ends of the strap 6 are respectively fixedly installed on the bottom surface of the pull plate 404.

[0026] More specifically, by rotating the knob 402, the threaded rod 401 is driven to rotate. Due to the thread action, the inner threaded sleeve 403 moves along the surface of the threaded rod 401, which in turn drives the pull plate 404 to move. The pull plate 404 drives the binding strap 6 to move, thereby cooperating with the pressure application component 5 to tighten or loosen the pipe, so as to adapt to pipes of different diameters and ensure that the pipe is tightly connected to the pipe opening 2.

[0027] A pressure-applying component 5 is inserted into the movable part of the cross plate 3 and the fastening component 4; such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, specifically, the pressure application component 5 includes a guide rod 501 that is movably inserted into the horizontal plate 3 and the pull plate 404, and an arc-shaped pressure plate 502 is fixedly installed at the bottom end of the guide rod 501. A pressure strip 504 is provided on the surface of the arc-shaped pressure plate 502, and through holes 503 are opened on the arc-shaped pressure plate 502 and the pressure strip 504. The strap 6 is movably inserted into the through hole 503.

[0028] More specifically, when the strap 6 passes through the through hole 503, the arc-shaped pressure plate 502 and the pressure strip 504 are pressed tightly against the pipe surface via the bottom end of the threaded rod 401, increasing the contact area with the pipe and improving the stability of the connection. At the same time, the guide rod 501 can move on the horizontal plate 3 and the pull plate 404, allowing the arc-shaped pressure plate 502 and the pressure strip 504 to be adjusted appropriately according to the shape and position of the pipe, enhancing the adaptability and flexibility of the device.

[0029] The moving part of the fastening component 4 is fixedly installed with a strap 6.

[0030] like Figure 2 and Figure 3 As shown, in some practical applications, a sealing groove 21 is provided on the surface of the pipe opening 2. When installing the pipe, the pipe is sleeved on the surface of the pipe opening 2 and the flange at its end is fixedly connected to the large flange on the surface of the pipe opening 2.

[0031] More specifically, the sealing groove 21 on the surface of the pipe opening 2 can be used to seal and fix the pipe to the surface of the pipe opening 2.

[0032] like Figure 2 and Figure 3 As shown, in some practical applications, the arc-shaped pressure plate 502 is located above the sealing groove 21 on the surface of the pipe opening 2, and the bottom end of the threaded rod 401 is in contact with the top surface of the arc-shaped pressure plate 502.

[0033] More specifically, when the knob 402 is rotated to move the threaded rod 401 down, the bottom end of the threaded rod 401 presses against the top surface of the arc-shaped pressure plate 502, forcing the arc-shaped pressure plate 502 to press tightly against the pipe surface, thereby achieving axial positioning and radial compression of the pipe, ensuring a tight fit between the pipe and the pipe opening 2, and preventing the pipe from loosening or falling off due to pressure.

[0034] like Figure 2 and Figure 3 As shown, in some practical applications, the pressure strip 504 and the binding strap 6 on the inner wall of the arc-shaped pressure plate 502 are attached to the surface of the pipe and are correspondingly set with the sealing groove 21 on the surface of the pipe opening 2.

[0035] More specifically, the pressure strip 504 presses tightly against the pipe surface under the action of the arc-shaped pressure plate 502, and the binding strap 6 wraps around the pipe and passes through the through hole 503 to further tighten the pipe, so that the pipe is sealed and fitted with the pipe opening 2 at the sealing groove 21.

[0036] In summary: When pipe connection is required, the pipe is fitted onto the surface of the pipe opening 2, and the flange at the end of the pipe is fixed to the flange on the surface of the pipe opening 2. Through the fastening component 4, the pipe is securely connected to the pipe opening 2 on the surface of the refrigeration unit body 1 by the cooperation of the binding strap 6 and the pressure application component 5, so as to prevent the pipe from falling off the pipe opening 2 under pressure and ensure the stability of the connection.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
