Description

Technical Field

[0001] The invention relates to the technical field of socket boxes, in particular to a power socket box for a refrigerated container. Background Art

[0002] In the cold chain logistics industry, refrigerated containers are key transportation equipment, and the stability and monitoring of their internal environment are of vital importance. The power socket box is a key component connecting the external power supply and the internal refrigeration system of the container. In order to improve energy management efficiency and ensure the safety and stable operation of equipment, some power socket boxes are installed with power monitoring gateways to record and analyze the power consumption of the internal equipment of the refrigerated container in real time. Through data analysis, energy waste can be discovered and corresponding energy-saving measures can be taken.

[0003] Furthermore, the operating environment of the power socket box for refrigerated containers is relatively humid. In order to ensure that the internal electrical components are not damaged by moisture, the power socket box requires a higher sealing performance. In order to ensure the sealing, all opening and closing parts and connection ports need to use sealing gaskets, and then lock and fix them with bolts to squeeze the sealing gaskets to achieve sealing.

[0004] When installing electrical parts, especially sockets, in current power socket boxes, it is necessary to use sealing gaskets at the joints, and then lock and fix them with bolts. This leads to slow production efficiency of the socket box, and in subsequent use, the sockets malfunction. The bolts rust due to the humid environment, making it difficult to remove and replace the sockets. In order to solve this problem, we propose a refrigerated container power socket box. Summary of the invention

[0005] In view of the problem that when the socket of the existing refrigerated container power socket box in the above or prior art fails, it is difficult to disassemble the screws due to rust, resulting in inconvenient maintenance, the present invention is proposed.

[0006] Therefore, an object of the present invention is to provide a refrigerated container power socket box.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: a refrigerated container power socket box, including a box body mechanism, which includes an electrical accommodating box, a cover arranged on the electrical accommodating box and sealingly matched with the top of the electrical accommodating box, and also includes a fixing ear arranged on the side of the electrical accommodating box away from the cover, and a socket hole and a power socket opened on one side of the electrical accommodating box, a fixing mechanism, which includes a clamping assembly arranged on one side of the electrical accommodating box and corresponding to the socket hole, and also includes a rubber sheet arranged on the clamping assembly, and a driving assembly sleeved on the outside of the clamping assembly.

[0008] As a preferred solution of the refrigerated container power socket box of the present invention, the clamping assembly includes a shell arranged on one side of the electrical housing box and corresponding to the socket hole, and also includes a plug-in through hole opened on the shell, and a clamping member arranged in a circular array in the inner cavity of the shell.

[0009] As a preferred solution of the refrigerated container power socket box of the present invention, the clamping member includes a clamping block arranged in a circular array in the inner cavity of the shell, and guide columns arranged at both ends of one side of the clamping block, and a guide groove is provided on one side of the shell that is attached to the electrical housing box, and the guide groove and the guide column are slidably matched.

[0010] As a preferred solution of the refrigerated container power socket box of the present invention, wherein: both ends of the clamping block are provided with tension springs, and one end of the tension spring away from the clamping block is fixedly connected to the inner wall of the shell.

[0011] As a preferred solution of the refrigerated container power socket box of the present invention, the rubber sheets are arranged in the inner cavity of the shell and distributed in a circular array along the edge of the plug-in vias, and the end of the rubber sheets in the circular array away from the plug-in vias is expanded outward.

[0012] As a preferred solution of the refrigerated container power socket box of the present invention, the socket hole and the plug-in via are matched with the plug-in section of the socket, and the inner diameter of the cylinder formed by the annular array of rubber sheets under the push of the annular array of clamping blocks is smaller than the diameter of the plug-in via.

[0013] As a preferred solution of the refrigerated container power socket box of the present invention, the shell is provided with a movable groove in an annular array on the circumferential side wall, and the drive assembly includes a drive ring rotatably sleeved on the outside of the shell, and a drive block in an annular array arranged on the inner wall of the drive ring and slidingly matched with the movable groove.

[0014] As a preferred solution of the refrigerated container power socket box of the present invention, wherein: the clamping block is provided with a pressing end, and the driving block is provided with a driving surface and a locking surface.

[0015] As a preferred solution of the refrigerated container power socket box of the present invention, wherein: the clamping block is provided with an arc surface on one side away from the top pressure end, and when the clamping blocks in the annular array are fitted together, the arc surface forms a circle, and the diameter of the circle formed by the arc surface is smaller than the outer diameter of the cylinder formed by the rubber sheets in the annular array.

[0016] As a preferred solution of the refrigerated container power socket box of the present invention, a limiting ring plate is provided on the inner wall of the driving ring, and the limiting ring plate fits the opening end of the shell, and the inner diameter of the limiting ring plate is the same as the plug-in through hole.

[0017] The beneficial effects of the refrigerated container power socket box of the present invention are as follows:

[0018] 1. The present invention realizes the fixing and removal of the socket by the clamping block through the rotation of the driving ring, so that when the socket on the socket box fails, it can be quickly replaced and repaired. At the same time, the setting of the rubber sheet makes its fixing effect better, and after the rubber sheet fixes the socket, it can improve the annular sealing through its own deformation, avoiding the situation that when the rubber sheets of the annular array are squeezed to fix the socket, moisture enters and causes electrical component failure due to the presence of gaps between the rubber sheets.

[0019] 2. The inner diameter of the rubber sheet arranged in a circular array in the present invention is smaller than the inner diameter of the socket hole when it is circular, so that when the driving component pushes the expanded rubber sheet to be circular, the pulling force on the root of the rubber sheet is small, avoiding the breakage of the rubber sheet, thereby improving the durability of the rubber sheet.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1, reference Figures 1 to 6, which is the first embodiment of the present invention, and provides a refrigerated container power socket box, which can realize the rapid disassembly and assembly of the socket and improve the efficiency of maintenance and replacement. The power socket box comprises a box body mechanism 1, which comprises an electrical container 101, a cover 102 arranged on the electrical container 101 and sealed with the top of the electrical container 101, and also comprises a fixing ear 103 arranged on the side of the electrical container 101 away from the cover 102, and a socket hole 104 and a power socket 105 opened on one side of the electrical container 101. The cover 102 is fixedly connected to the top of the electrical container 101 by multiple fixing bolts, and a sealing strip is arranged in the middle. The electrical container 101 has electrical components such as a circuit breaker, a power monitoring module and a socket fixedly installed inside, and the power monitoring module is electrically connected to the socket. The electrical container 101 is fixedly installed on the outside of the refrigerated container by bolts through the fixing ear 103. The socket hole 104 and the power socket 105 are opened on the same side of the electrical container 101, and multiple socket holes 104 are opened for the installation of multiple sockets.

[0035] The fixing mechanism 2 includes a clamping assembly 3 which is arranged on one side of the electrical container box 101 and corresponds to the socket hole 104, a rubber sheet 201 which is arranged on the clamping assembly 3, and a driving assembly 4 which is sleeved on the outside of the clamping assembly 3. A plurality of clamping assemblies 3 are fixedly installed on one side of the electrical container box 101, and the number of the clamping assemblies 3 is the same as the number of the socket holes 104. The socket is inserted into the socket hole 104 through the clamping assembly 3, and then the clamping assembly 3 clamps and fixes the socket under the action of the driving assembly 4. When clamping and fixing the socket, the clamping assembly 3 first clamps the rubber sheet 201. The rubber sheet 201 here acts as a sealing gasket to prevent moisture from the outside of the electrical container box 101 from entering the box body and causing damage to the internal electrical components.

[0036] The clamping assembly 3 includes a shell 301 arranged on one side of the electrical housing box 101 and corresponding to the socket hole 104, and also includes a plug-in through hole 302 opened on the shell 301, and a clamping member 5 in a circular array arranged in the inner cavity of the shell 301. The shell 301 and the side wall of the electrical housing box 101 are welded, the plug-in through hole 302 corresponds to the socket hole 104, and a plurality of clamping members 5 are provided. The clamping member 5 clamps and fixes the socket under the action of the driving assembly 4.

[0037] The clamping member 5 includes a clamping block 501 arranged in an annular array in the inner cavity of the shell 301, and a guide column 502 arranged at both ends of one side of the clamping block 501. A guide groove 303 is opened on one side of the shell 301 that is close to the electrical housing box 101, and the guide groove 303 and the guide column 502 are slidably matched. The direction of the guide groove 303 is the same as the moving direction of the clamping block 501 driven by the drive component 4, so that the clamping blocks 501 of the annular array are close to the axis of the shell 301 along the guide groove 303. After moving close, the clamping blocks 501 of the annular array are formed into an annular column to squeeze the rubber sheet 201 to fit the side wall of the plug-in fixed end of the socket, and the socket is fixed by the friction force of the rubber sheet 201 and the clamping force of the clamping block 501.

[0038] Tension springs 304 are provided at both ends of the clamping block 501, and the end of the tension spring 304 away from the clamping block 501 is fixedly connected to the inner wall of the shell 301. Through the setting of the tension spring 304, after the socket is removed, the clamping block 501 moves in the direction away from the axis of the shell 301 under the action of the tension spring 304, so as to facilitate the plugging of a new socket. If there is no tension spring 304, the clamping block 501 will not be limited after the faulty socket is removed, because when it collides with the socket box body during operation, its vibration will drive part of the clamping block 501 to move in the direction away from the axis, while the other part of the clamping block 501 will move in the direction close to the axis. At this time, the clamping block 501 moving in the direction close to the axis will block the plug-in through hole 302 on the shell 301, making it impossible to insert the new socket.

[0039] When in use, the drive assembly 4 is rotated to unlock the squeezing of the clamping block 501 by the drive assembly 4, and then the clamping block 501 moves around and spreads close to the inner wall of the shell 301 under the tension of the tension spring 304, and then the faulty socket is pulled out, and the wiring behind the socket is disassembled and connected to the new socket using a tool, and then the new socket is inserted from the middle of the rubber sheet 201 of the ring array with the wiring, and passes through the plug-in hole 302 and the socket hole 104, so that the wiring terminal of the socket is located inside the box, and finally the drive assembly 4 is rotated to push the spread clamping block 501 to the center position, thereby squeezing the rubber sheet 201 to fit the side wall of the new socket to complete the fixation of the new socket.

[0040] In summary, the present invention improves the efficiency of repairing and replacing the sockets on the socket box.

[0041] Example 2, reference Figures 1 to 8, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a rubber sheet 201 for a refrigerated container power socket box, which improves the sealing effect after the socket is fixed. The rubber sheet 201 is arranged in the inner cavity of the shell 301 and is distributed in a ring array along the edge of the plug-in hole 302. The end of the ring-shaped array rubber sheet 201 away from the plug-in hole 302 is expanded outward. The socket hole 104 and the plug-in hole 302 are matched with the plug-in section of the socket. The inner diameter of the cylinder formed by the ring-shaped array rubber sheet 201 under the push of the ring-shaped array clamping block 501 is smaller than the diameter of the plug-in hole 302.

[0042] The rubber sheets 201 distributed in the annular array are expanded so that the socket plays a guiding role when plugging in, and the plugging efficiency of the socket is improved. The rubber sheets 201 distributed in the annular array are pushed outward by the clamping block 501 to form a cylindrical shape. Figure 7-8 As shown, the side walls of adjacent rubber sheets 201 are in contact with each other and are in a zero contact state.

[0043] Furthermore, Figure 7 The state in the middle is the state where the socket is not plugged in. At this time, the inner diameter of the cylindrical rubber sheet 201 is smaller than the plug-in hole 302, and the outer diameter of the socket plug-in section is the same as the socket hole 104 and the plug-in hole 302. Therefore, the inner diameter of the cylindrical rubber sheet 201 is smaller than and also smaller than the outer diameter of the socket plug-in section. When the socket is inserted, the clamping block 501 is pushed by the driving component 4, so that the rubber sheet 201 expanded in the annular array first fits the outer wall of the socket plug-in section. At this time, there is a small gap between the two adjacent rubber sheets 201, and then the driving component 4 continues to push and squeeze the rubber sheet 201. Because the rubber sheet 201 is already close to the outer wall of the socket plug-in section, continued squeezing will prevent the rubber sheet 201 from moving toward the axial direction of the socket plug-in section, so that the rubber sheet 201 will be squeezed and deformed, the thickness will become thinner, and it will deform and expand in the direction of the adjacent two sides, so that the side walls of the two adjacent rubber sheets 201 that originally had a small gap are squeezed against each other. This not only improves the sealing performance and prevents external moisture from entering the box, but also prevents the rubber sheet 201 from breaking due to the extrusion, pushing and pulling of the root outer diameter of the rubber sheet 201 by the drive component 4.

[0044] Specifically, under normal circumstances, when the annular array of the rubber sheet is circular, its inner diameter is equal to the outer wall of the socket plug section, and then under the pushing and squeezing of the driving component 4, it can hug the outer wall of the socket plug section to form a seal. However, when the driving component 4 pushes and squeezes the rubber sheet 201, the rubber sheet 201 will become thinner. When the conventional rubber sheet 201 and the rubber sheet 201 in the present invention are of the same thickness and are arranged in a circular shape, the distance from the outer diameter of the conventional rubber sheet 201 to the outer wall of the socket plug section is greater than the distance from the outer diameter of the rubber sheet 201 in the present invention to the outer wall of the socket plug section. Figure 8 As shown, when the rubber sheet 201 of the present invention is squeezed into a round shape, the connection end with the housing 301 is inclined toward the axial direction, so that the inner diameter of the round rubber sheet 201 is smaller than the outer diameter of the socket plug section. Therefore, after the rubber sheet 201 is squeezed and deformed, the pulling force on the root of the outer diameter of the conventional rubber sheet 201 is greater than the pulling force on the root of the outer diameter of the rubber sheet 201 of the present invention. Therefore, the rubber sheet 201 of the present invention has higher durability. The rest of the structure is the same as that of Example 1.

[0045] Example 3, reference Figures 1 to 9 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a driving assembly 4 of a refrigerated container power socket box, including the refrigerated container power socket box in the above embodiment, which includes a shell 301 with a circular array of movable grooves 305 on the circumferential side wall, the driving assembly 4 includes a driving ring 401 rotatably sleeved on the outside of the shell 301, and a driving block 402 arranged in a circular array on the inner wall of the driving ring 401 and slidingly matched with the movable groove 305, the driving ring 401 is provided with an anti-slip groove on the outside to facilitate the knob operation, the clamping block 501 is always in contact with the driving block 402 under the action of the tension spring 304, and the length of the movable groove 305 needs to adapt to the rotation angle of the driving ring 401.

[0046] The clamping block 501 is provided with a pressing end 503, and the driving block 402 is provided with a driving surface 403 and a locking surface 404. The side of the clamping block 501 close to the inner wall of the housing 301 is provided with a pressing end 503, and the pressing end 503 is provided in a convex shape at the middle end of one side of the driving block 402, and the driving surface 403 and the locking surface 404 are provided on the side of the driving block 402 away from the driving ring 401, and the distance between the two ends of the driving surface 403 and the inner wall of the driving block 402 tends to gradually increase. The position with the largest distance transitions to the locking surface 404, and the locking surface 404 is arranged in an arc shape, so that after the top pressing end 503 on the clamping block 501 transitions to the locking surface 404 along the driving surface 403, a locking platform is provided through the arc-shaped locking surface 404, which prevents the tension of the tension spring 304 from driving the clamping block 501 to reset, so that the top pressing end 503 of the clamping block 501 pushes the driving block 402, and then pushes the driving ring 401 to rotate along the driving surface 403 to unlock the fixation of the socket.

[0047] Furthermore, the driving ring 401 rotates to drive the driving block 402 to squeeze the pressing end 503, so that when the pressing end 503 enters the arc-shaped locking surface 404, the driving ring 401 can continue to be slightly rotated so that the pressing end 503 slides on the locking surface 404 without affecting the fixation of the socket.

[0048] The clamping block 501 is provided with an arc surface 504 on one side away from the pressing end 503 . When the annular array clamping blocks 501 are attached to each other, the arc surface 504 forms a circle, and the diameter of the circle formed by the arc surface 504 is smaller than the outer diameter of the cylinder formed by the annular array rubber sheet 201 .

[0049] In this embodiment, when the clamping block 501 pushes the cylinder formed by the rubber sheet 201, the arc surface 504 on the clamping block 501 of the annular array does not form a circle. At this time, there is a gap between the clamping blocks 501 of the annular array, and it is necessary to continue to move toward the axial direction of the shell 301 to form a circle. After continuing to move, the rubber sheet 201 is squeezed to fix the socket, wherein the arc surface 504 is provided with a chamfer near the root of the rubber sheet 201, and the chamfer matches the inclined end of the connection between the rubber sheet 201 and the shell 301, so as to avoid shear force on the root of the rubber sheet 201 when squeezing the rubber sheet 201, causing the rubber sheet 201 to break.

[0050] A limit ring plate 405 is disposed on the inner wall of the driving ring 401 , and the limit ring plate 405 fits the opening end of the housing 301 , and the inner diameter of the limit ring plate 405 is the same as the plug-in through hole 302 .

[0051] In this embodiment, the top of the shell 301 is open, and the opening of the shell 301 is closed by setting the limiting ring plate 405, so that the clamping block 501 is confined inside the shell 301 and can only move along the guide groove 303.

[0052] The rest of the structure is the same as that of Example 2.

[0053] When a socket on the power socket box of the refrigerated container fails, the drive ring 401 is rotated to drive the drive block 402 to rotate and unlock. The unlocking process is as follows: the drive block 402 rotates so that the top pressure end 503 on the clamping block 501 enters the driving surface 403 from the locking surface 404 on the drive block 402. Under the pull of the tension spring 304, the clamping block 501 gradually moves away from the rubber sheet 201. The rubber sheet 201 recovers its expanded state under its elastic action, thereby unlocking the fixation of the faulty socket. Then the faulty socket is pulled out, and the wiring is disconnected and connected to a new socket. Then, the new socket is inserted into the expanded rubber sheet 201 so that its wiring is located inside the box. Then, the drive ring 401 is rotated so that the drive ring 401 drives the drive block 402 to push the clamping blocks 501 to be close to each other to form a cylinder. Then, the rubber sheet 201 is squeezed through the arc surface 504, so that the rubber sheet 201 is deformed, sealed and fixes the socket.

[0054] 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 preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
