Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically a drainage component for refrigeration equipment. Background Technology

[0002] A refrigeration machine or refrigeration unit, as well as the equipment, devices, and components that make up the refrigeration machine or refrigeration unit. It usually includes one or more of the following parts of the machine and equipment: compressor, fan, condenser, evaporator, generator, absorber, receiver, throttling mechanism, connecting pipes and valves, enclosure devices and components, other heat exchange equipment and container equipment, and electrical control equipment, etc.

[0003] A search revealed a drainage assembly for refrigeration equipment with application number CN202422758029.8. The assembly includes a drain pipe, one end of which is fitted with a drain pipe, and a connecting mechanism mounted on the drain pipe. The connecting mechanism comprises a transmission unit and a limiting unit, the limiting unit providing a limit for the movement of the drain pipe and the connecting ring. This invention, by providing a connecting mechanism, allows for connection between the drain pipe and the drain pipe to drain water from the refrigerator. When this connection is needed, a rotating wheel can be applied to release the limiting position of the connecting ring and the drain pipe. The axial movement of the connecting ring, via guide blocks and guide grooves, pushes the clamping blocks closer together to contact the outer wall of the drain pipe. Applying rotational force to the wheel again fixes the connecting ring, thus limiting the movement of the clamping blocks. This further improves clamping efficiency and facilitates the installation and disassembly of the drain pipe and the drain pipe.

[0004] While the above method can solve the drainage problem, the drainage pipes are divided into two parts. During use, the sewer pipe and the drainage pipe correspond one-to-one. However, most sewer pipes are vertical. Therefore, when using this drainage component, the sewer pipe needs to be modified to adapt to the system, which will greatly increase the cost of use. Therefore, it is necessary to make improvements. Utility Model Content

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a drainage component for refrigeration equipment. This component addresses the issue that, during use, there is a one-to-one correspondence between drain pipes and sewer pipes. Since most drain pipes are vertical, modifications to the drain pipes are necessary to adapt to this component, significantly increasing operating costs.

[0006] Technical solution To achieve the above-mentioned objective, this utility model provides the following technical solution: a drainage component for refrigeration equipment, comprising a first drainage pipe, two movable abutment plates embedded on the surface of the first drainage pipe, a spring fixedly connected inside the abutment plate, the other end of the spring fixedly connected to the inner surface of the first drainage pipe, a limiting plate provided below the abutment plate, one side of the limiting plate being rounded, a long plate movably connected to one side of the limiting plate, and a second drainage pipe fixedly connected to the other end of the long plate, connecting pieces fixedly sleeved on the outer surfaces of both the first and second drainage pipes, a rotatable sealing plate provided in the second drainage pipe, a round rod provided inside the sealing plate, a gear provided on the outer surface of the round rod, and a rack meshing with the outer surface of the gear; a rotating mechanism provided on the outer surface of the connecting piece.

[0007] Furthermore, the rotating mechanism includes a threaded rod that is movably sleeved between two connecting plates. One end of the outer surface of the threaded rod is threadedly sleeved with the connecting plate, and the other end is movably sleeved with another connecting plate. The top end of the threaded rod is provided with a groove.

[0008] Furthermore, the rotating mechanism also includes a straight rod movably sleeved on one side of the connecting piece, the straight rod passing through the two connecting pieces, and being constrained by an end cap set on the straight rod to form a snap-fit.

[0009] Furthermore, the two abutment plates are distributed symmetrically in mirror image with respect to the center of the first drainage pipe.

[0010] Furthermore, the outer surface of the abutment plate is made of rubber.

[0011] Furthermore, one end of the rack is located inside the second drainage pipe, and the other end is fixedly connected to the outer surface of the first drainage pipe.

[0012] Furthermore, a gap is reserved between the abutment plate and the position where it is embedded in the inner surface of the first drainage pipe.

[0013] Beneficial effects Compared with the prior art, the present invention provides a drainage component for refrigeration equipment, which has the following advantages: 1. Rotating the threaded rod 8 causes the second drainage pipe 2 to move axially along the straight rod 9 towards the first drainage pipe 1. The second drainage pipe 2 pulls the long plate 10 to press against the limiting block connected to the clamping plate 7 (both are rounded). The clamping plate 7 is fixed to the inner surface of the first drainage pipe 1 by the spring 11, and a gap is reserved at the embedding point of the first drainage pipe 1. Under the pressure of the long plate 10, the clamping plate 7 expands towards the inner wall of the drainage pipe, adhering to the pipe wall by the deformation ability of the rubber material. Combined with the through-locking limit of the straight rod 9 and the support of the connecting piece 3 for the drainage pipe, a linkage of "rotating the threaded rod 8, moving the second drainage pipe 2, pressing with the long plate 10, and expanding and adhering with the clamping plate 7" is formed, realizing the stable fixation of the component in the drainage pipe and preventing the first drainage pipe 1 from detaching due to drainage overflow.

[0014] 2. During drainage, rotating the threaded rod 8 moves the second drainage pipe 2 towards the first drainage pipe 1. The rack 6 extends into the second drainage pipe 2 and meshes with the gear of the round rod 5, causing the round rod 5 to flip and open the sealing plate 4, opening the drainage channel. When not draining, rotating the threaded rod 8 in the opposite direction moves the second drainage pipe 2 away from the first drainage pipe 1. The rack 6 pulls the gear in reverse, and the round rod 5 drives the sealing plate 4 to reset and seal, closing the channel and preventing the leakage of cold air from the refrigeration equipment. On the other hand, the first drainage pipe 1 and the second drainage pipe 2 form an integrated structure through the connection of the connecting piece 3 and the threaded rod 8, which does not require separate assembly or modification of the original drainage pipes. Relying on the linkage of each component, it can be installed and used immediately, avoiding the trouble of missing parts or separate installation, and improving the efficiency of use.

[0017] To more clearly illustrate the overall concept of this utility model, a detailed description is provided below with reference to the accompanying drawings.

[0018] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same solution or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0022] Please see Figures 1-6 This utility model proposes a drainage component for refrigeration equipment, including a first drainage pipe 1. During use, the condensate in the refrigeration equipment needs to be discharged through the drainage component. The operator first needs to place the first drainage pipe 1 into the drainage pipe channel. When the first drainage pipe 1 is placed into the drainage pipe, in order to fix the first drainage pipe 1 inside the drainage pipe and prevent the first drainage pipe 1 from falling off due to drainage overflow. The outer surface of drainage pipe 1 is inlaid with two movable clamping plates 7, which are symmetrically distributed around the center of drainage pipe 1. Figure 5 It can be observed that a limiting block is provided below the clamping plate 7. One side of the limiting plate is rounded. A long plate 10 is movably connected to one side of the limiting block, which is also rounded. Because the limiting block and the long plate 10 are rounded, the compression between the long plate 10 and the limiting block will be smoother.

[0023] A second drainage pipe 2 is fixedly connected to the other end of the long plate 10. A connecting piece 3 is fixedly sleeved on the outer surface of both the first drainage pipe 1 and the second drainage pipe 2. A straight rod 9 is movably sleeved on one side of the connecting piece 3. The straight rod 9 passes through the two connecting pieces 3 and is limited by the end cap set on the straight rod 9 (it can be observed from the attached figure that one end of the straight rod 9 is provided with an end cap) to form a snap-fit, thereby limiting the movement between the first drainage pipe 1 and the second drainage pipe 2. A threaded rod 8 is movably sleeved between two connecting pieces 3. One end of the outer surface of the threaded rod 8 is threadedly sleeved with the connecting piece 3, and the other end is movably sleeved with the other connecting piece 3. At this time, the first drainage pipe 1 is placed into the drainage pipe, and the connecting piece 3 will abut against the outer surface of the drainage pipe, forming a support. The operator presses on the outer surface of the connecting piece 3 and rotates the threaded rod 8, causing the second drainage pipe 2 to move along the outer surface of the straight rod 9 towards the first drainage pipe 1. At the same time, a groove is provided at the top of the threaded rod 8, and the threaded rod 8 can also be rotated using external tools. During the process of the second drainage pipe 2 moving towards the first drainage pipe 1, the long plate 10 fixedly connected to the second drainage pipe 2 will continuously squeeze the limiting block connected to the pressing plate 7, and the inside of the pressing plate 7 is fixedly connected to a spring 11, the other end of which is fixedly connected to the inner surface of the first drainage pipe 1 (see attached). Figure 6(It can be observed in the middle); and there is a gap between the position where the clamping plate 7 is embedded in the inner surface of the first drainage pipe 1. When the long plate 10 is pressed against the limiting block connected to the clamping plate 7, the clamping plate 7 will move, so that the clamping plate 7 can move towards the inner wall of the drainage pipe. The outer surface of the clamping plate 7 is made of rubber material, which has good deformation ability, so that the clamping plate 7 can better fit into the inner wall of the drainage pipe under the pressure of the long plate 10. The clamping plate 7 will press against the inner wall of the drainage pipe to form a fixation, so that the first drainage pipe 1 will not be detached from the inside of the drainage pipe when the water flows out during drainage.

[0024] When drainage is not required, in order to prevent cold air from the refrigeration equipment from flowing out of drain pipe 1 and drain pipe 2, a rotatable sealing plate 4 is provided in drain pipe 2. The sealing plate 4 has a round rod 5 inside, and a gear is provided on the outer surface of the round rod 5. A rack 6 is meshed on the outer surface of the gear. One end of the rack 6 is located inside drain pipe 2, and the other end is fixedly connected to the outer surface of drain pipe 1. When drain pipe 2 moves towards drain pipe 1, the rack 6 will extend into the interior of drain pipe 2, thereby driving the gear to rotate, causing the round rod 5 to drive the sealing plate 4 to flip open, thus allowing drainage. During the rotation of the sealing plate 4, the long plate 10 will disengage from the limiting plate below the clamping plate 7, so that the clamping plate 7 returns to its initial position under the action of the spring 11. At this time, the operator can remove the second drainage pipe 2 from the sewer pipe.

[0025] When the threaded rod 8 is rotated again, the second drain pipe 2 is moved away from the first drain pipe 1. At this time, the rack 6 will drive the gear on the round rod 5 to rotate again, thereby causing the sealing plate 4 to return to the initial position and block the passage of the second drain pipe 2, so that cold air will not leak out from the second drain pipe 2 when cooling.

[0026] Meanwhile, the No. 1 drainage pipe and the No. 2 drainage pipe are connected by the connecting piece 3 and the threaded rod 8, forming a whole without the need for separate assembly. This makes them more convenient to use, requiring no modification to other drainage pipes. There is no need to worry about missing parts or the need to install a particular pipe separately.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
