Description

Technical Field

[0001] This application relates to the technical field of cold box sockets, and particularly to a waterproof immersion structure for cold box sockets. Background Art

[0002] In the field of refrigerated container transportation, cold box sockets, as key components connecting power sources and refrigeration equipment, their technical background and development are particularly important. With the booming development of the global container shipping industry, the transportation demand for refrigerated containers has increased sharply. Especially in the transportation of goods that require strict temperature control, such as food and medicine, the application of refrigerated containers is becoming more and more widespread. The stability and efficiency of their onshore power supply technology are crucial for ensuring the quality of goods and reducing losses.

[0003] In the current context of the booming global trade and the surging demand for cold chain logistics, traditional onshore power supply methods are facing unprecedented challenges. Among them, a significant and urgent problem to be solved is the insufficient waterproof performance of plugs. Due to the complex and changeable port environment, often encountering bad weather such as strong winds and sudden rains, traditional power supply plugs are often difficult to effectively resist the intrusion of moisture. This may not only lead to potential safety hazards such as short circuits and equipment damage, but also pose a serious threat to the quality of goods in cold chain logistics. Because any power supply interruption may affect the temperature control in the refrigerated container, thereby damaging the freshness and safety of the goods. Therefore, how to improve the waterproof performance of plugs has become one of the important directions of technological innovation in the current cold chain logistics field. Summary of the Invention

[0004] This device provides a waterproof immersion structure for cold box sockets, and the specific implementation is as follows:

[0005] A waterproof immersion structure for cold box sockets, comprising:

[0006] A power supply box body and a socket arranged integrally, and the socket is arranged in a downward inclined shape with respect to the vertical power supply box body;

[0007] A sealing structure provided at the front end of the socket, which includes an annular body, and an annular convex is provided inside the annular body;

[0008] A rubber ring sleeve installed at the front end of the plug. On the inner side of the rubber ring sleeve, a convex portion is provided around the middle base of the plug. Inner convex rings are provided in front of and behind it, and a deformation ring is provided at the middle position between the two inner convex rings on the outer side of the rubber ring sleeve. When the plug is inserted into the socket, the deformation ring abuts against the annular convex and deforms, and the deformation drives the inner convex ring to tilt and seal the edge of the base portion.

[0009] Based on the above technical solution, in a refrigerated container, due to the special environment, the connection between the plug and the socket not only needs to ensure the stability of electrical conduction, but also needs to consider requirements such as waterproofing, moisture-proofing, and adapting to low-temperature environments. By installing the socket in a downward-tilted posture compared to the power supply box body, rainwater intrusion can be effectively prevented, ensuring safety during the power supply process.

[0010] Preferably, the inner side of the annular body is set as an inclined surface, and the front end of the rubber ring sleeve is set as a plug-in ring that abuts against the inclined surface.

[0011] Preferably, the front end of the plug-in ring is set as an inclined surface structure, and a limiting groove matching the plug-in ring is provided on the inclined surface.

[0012] Preferably, the surface of the deformation ring facing the annular convex is set as an inclined shape.

[0013] Preferably, both the front and rear surfaces of the plug-in ring are set as inclined surface structures.

[0014] Based on the above technical solution, by installing a sealing structure and a rubber ring sleeve in the axial plugging channel of the plug and the socket, and using the axial deformation of the rubber ring sleeve during axial plugging, the edge of the plug is sealed, preventing the plug from being invaded by disordered rainwater when blown by the wind during the power supply process.

[0015] Preferably, a cover body is integrally formed outside the annular body, and the diameter of the cover body is larger than the diameter of the plug.

[0016] Based on the above technical solution, the cover body integrally formed outside the annular body can also be formed integrally by means of threaded connection; the overall posture of the cover body is also downward-tilted, which can block most of the rainwater, and the process of the plug being inserted upward can be completed inside the cover body, further preventing rainwater intrusion during this action.

[0017] Preferably, a sealing ring that abuts against the end surface of the plug-in part in the plug is provided at the end surface of the annular body.

[0018] Preferably, the inner side surfaces of the two inner convex rings are both set as inclined surface structures that abut against the convex parts.

[0019] Based on the above technical solutions, when the sealing ring is used in combination with a specific sealing structure, especially to form an L-shaped sealing structure, its sealing effect will be significantly improved. The design principle of the L-shaped sealing structure lies in making use of the elasticity of the sealing ring and the shape advantages of the sealing structure to jointly form a multi-level sealing barrier. This structure can not only prevent the penetration of liquid in the horizontal direction, but also form an effective seal in the vertical direction, thus greatly enhancing the overall sealing performance; when the liquid tries to penetrate, it must bypass multiple corners and obstacles, which greatly increases the difficulty of penetration. In addition, the L-shaped structure can also absorb and disperse external pressure to a certain extent, reducing the risk of seal failure caused by pressure changes.

[0020] In summary, the present application includes the following beneficial technical effects:

[0021] 1. By installing the socket in a downward-tilted manner relative to the power supply box body, the present utility model can effectively prevent rainwater from entering to a certain extent, thereby improving the safety during the power supply process. Rainwater usually flows downward along the surface of an object. When the socket is installed in a downward-tilted manner relative to the power supply box body, even if rainwater splashes or flows onto the power supply box body, due to the tilt angle of the socket, it is very difficult for the rainwater to penetrate into the interior along the interface between the socket and the box body, thus reducing the safety risks such as short circuits and electric leakage caused by rainwater intrusion.

[0022] 2. By installing a sealing structure and a rubber ring sleeve in the axial insertion channel of the plug and the socket, the rubber ring sleeve will deform during axial insertion and closely fit the edge of the plug to form a waterproof barrier. In this way, even if the refrigerated container is in an outdoor or humid environment, it can effectively prevent rainwater, moisture, etc. from invading through the gap between the plug and the socket, ensuring the safety and reliability of the electrical connection.

[0023] 3. The structure of the present utility model is simple. The upward insertion process of the plug is completed inside the cover body, further enhancing the waterproof effect. In traditional designs, the plug often needs to be exposed to the external environment during insertion, which increases the risk of rainwater intrusion. In this design, the plug is always under the protection of the cover body during the insertion process. Even if there is rainwater outside, it cannot directly contact the joint part of the plug and the socket. Even under harsh rainy conditions, it can ensure the smooth progress of the insertion action and avoid problems such as short circuits or damage caused by rainwater intrusion.

[0039] An embodiment of the present application discloses a waterproof immersion structure for a cold box socket.

[0040] Embodiment 1

[0041] Referring to Figures 1 to 3 , this embodiment discloses a waterproof immersion structure for a cold box socket, including a power supply box body 1 and a socket 2 arranged integrally. The socket 2 is arranged in a downward inclined shape relative to the vertical power supply box body 1. In this structure, a sealing structure 4 is provided at the front end of the socket 2. In this structure, the front end of the base part 503 of the plug 5 is a plug-in part 501, and the rear end is a power connection part 502. When the plug-in part 501 is inserted into the socket 2, it abuts against the sealing structure 4, so that the sealing effect is good during the power supply process. Moreover, the socket 2 and the plug 5 are inserted obliquely, and it is not easy to generate accumulated water, and the waterproof immersion effect is good.

[0042] Embodiment 2

[0043] Referring to Figures 1 to 7 , based on the above embodiment, this embodiment also discloses a waterproof immersion structure for a cold box socket, further including a rubber ring sleeve 6 installed at the front end of the plug 5 and a sealing structure 4 provided at the front end of the socket 2. In this structure, the sealing structure 4 includes an annular body 404, an annular convex 405 is provided inside the annular body 404, and a sealing ring 7 that abuts against the end face of the plug-in part 501 of the plug 5 is provided at the end face of the annular body 404.

[0044] On the inner side of the rubber ring sleeve 6, a raised part 504 is provided on the periphery of the base part 503 of the plug 5. Inner convex rings 601 are provided in front of and behind the raised part 504, and a deformation ring 602 is provided at the middle position between the two inner convex rings 601 on the outer side of the rubber ring sleeve 6. When the plug 5 is inserted into the socket 2, the deformation ring 602 deforms after abutting against the annular convex 405, and the deformation drives the inner convex rings 601 to tilt and seal the edge of the base part 503. In this structure, the inner side surfaces of the two inner convex rings 601 are both set as inclined surface structures that abut against the raised part 504.

[0045] The inner side of the annular body 404 is set as an inclined surface 401, and the front end of the rubber ring sleeve 6 is provided with a plug-in ring 603 that abuts against the inclined surface 401. The front end of the plug-in ring 603 is set as an inclined surface structure, and a limiting groove 403 that matches the plug-in ring 603 is provided on the inclined surface 401. In this structure, the surface of the deformation ring 602 facing the annular convex 405 is set as an inclined shape, and the front and rear surfaces of the plug-in ring 603 are both set as inclined surface structures.

[0046] Embodiment 3

[0047] Referring to Figures 1 to 7, based on the above embodiments, the present embodiment also discloses a waterproof structure for a cold box socket. A cover 402 is integrally formed outside the annular body 404. The diameter of the cover 402 is larger than the diameter of the plug 5. In this structure, the cover 402 and the socket 2 are inclined in the same direction, both are arranged in a downward inclined shape relative to the power supply box body 1, and the cover 402 and the socket 2 can be connected by threads.

[0048] The specific implementation process is as follows: When the plug 5 is inserted into the socket 2, the insertion part 501 is inserted into the inner side of the annular body 404; during this period, the insertion ring 603 always abuts against the inclined surface 401. As the insertion ring 603 is snapped into the limit groove 403, it indicates that the plug 5 and the socket 2 are inserted in place; at this time, the annular convex 405 acts on the deformation ring 602. Since the deformation ring 602 and the inner convex ring 601 are an integral rubber structure, and the deformation ring 602 is located between the two inner convex rings 601 in the same axial direction, after the deformation ring 602 deforms outward, the inner convex ring 601 generates a synchronous outward inclination. The inner convex ring 601 seals the edge of the insertion part 501 through the inclined deformation, thereby further improving the waterproof effect.

[0049] Many other changes and modifications can be made without departing from the concept and scope of the present invention. It should be understood that the present invention is not limited to a specific implementation manner, and the scope of the present invention is defined by the appended claims.
