Description

Technical Field

[0001] This invention relates to the field of power equipment technology, specifically to a primary and secondary integrated ring network box. Background Technology

[0002] The integrated primary and secondary ring network box (also known as the "integrated primary and secondary intelligent ring network cabinet") is an intelligent and modular power distribution device that integrates primary and secondary equipment in the power distribution network. It is mainly used in scenarios such as ring network power supply, terminal power supply, and segmented control in 10kV or 20kV medium voltage power distribution systems.

[0003] A typical integrated ring main unit (RMU) consists of an outer shell and multiple functional cabinets housed within it. Each cabinet integrates primary and secondary components for power distribution, protection, measurement and control, and communication. Currently, there are two main installation methods for this type of RMU: one is to transport the pre-assembled shell (by welding or bolting) to the site, then open the access doors on the shell and install each functional cabinet one by one; the other is to pre-install all cabinets on the base plate, then use hoisting equipment to "slide" the entire shell over the pre-positioned cabinets from above, and finally fix the shell to the base plate by welding or bolting.

[0004] In this field, to address the challenges of transporting the entire casing, some methods save space by disassembling individual components (such as transporting the top cover, side panels, etc. separately). However, when transporting components separately, the following problems still exist:

[0005] Traditional modular designs rely on on-site welding or complex bolt fastening, requiring large hoisting equipment and multiple professionals, making them difficult to implement in narrow or remote locations (such as mountainous areas or urban alleyways). Furthermore, in order to simplify the modular structure, the automatic limit mechanism of the maintenance door is often omitted, resulting in the door being unable to be fixed after being opened and potentially closing on its own due to wind or other reasons, increasing maintenance risks. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a primary and secondary integrated ring network box that can be assembled after being transported to the installation location, thus avoiding the occupation of external space during transportation.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a primary and secondary integrated ring network box, comprising:

The other side of the connecting piece is connected to the power mechanism. The middle part of the connecting piece near the spring is fixedly connected to one end of the guide rod. The other end of the guide rod passes through the spring and the support plate into the movable cavity and is connected to the inner limiting member. The other end of the inner limiting member is connected to the first limiting rod or the second limiting rod.

[0023] Furthermore, the inner limiting component of the limiting assembly connected to the front structure only includes an inner block, and the inner limiting component of the limiting assembly connected to the rear structure includes an inner block, a first limiting block, and a second limiting block. One end of the guide rod located in the moving cavity is fixedly connected to the side wall of the inner block, the outer wall of the inner block is slidably connected to the moving cavity, and a cavity is opened at the end of the inner block away from the guide rod. The first limiting rod and the second limiting rod are respectively located in the cavities of the two inner blocks, and one end of the first limiting block and the second limiting block are fixedly connected to the cavity of the inner block.

[0024] The surfaces of the first limiting rod and the second limiting rod are each provided with a first limiting opening, a second limiting opening, and a ramp.

The two second ropes are wound in opposite directions on the third rod, and the end of the third rod outside the protective cover is fixedly connected to both the knob and the first rope. The other end of the first rope is fixedly connected to the rear door or the rear second door, and the two second ropes are located on both sides of the partition.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] This type of integrated ring mesh box, which combines primary and secondary components, is made by disassembling the box into independent parts such as bottom structure, top cover, left and right side structure, and front and rear side structure. During transportation, the left and right side structure can be folded and stacked on the bottom of the top cover, while the front and rear side structure can be laid flat separately, which greatly saves transportation space and avoids collisions, dents, and paint peeling during overall transportation, thus improving the integrity of product transportation and logistics efficiency.

[0029] This type of integrated ring network box, which combines primary and secondary components, requires the bottom structure and power cabinet to be fixed during installation. Then, the folded left and right side structures are unfolded and inserted into the bottom slide rail. Finally, the front and rear side structures are inserted into the bottom plate and top cover slide rail from the right side. No large hoisting equipment is required, and one or two people can complete the assembly. It is suitable for narrow road sections or space-constrained scenarios.

[0030] This type of integrated ring mesh box with primary and secondary components has a right-angled trapezoidal cross section for the outer limiting component. When the front and rear frames are inserted, the spring can be automatically compressed and the outer limiting component can be pushed to reset without manual operation.

[0031] This type of integrated ring mesh box uses a spring-driven inner / outer limit component to automatically lock the front and rear doors after they are opened, preventing them from closing on their own. After closing, it is automatically fixed to prevent accidental opening and avoids the door from pinching people or affecting operation during maintenance.

[0032] This type of integrated ring cage with primary and secondary components has a power mechanism that is linked by a knob and a rope. Turning the knob can simultaneously release the limits of the front and rear side structures, and the rear door can be automatically closed by the first rope. There is no need to go around to the back of the cage. When disassembling, you only need to pull the rope to release the outer limit piece and quickly disassemble the cage.

[0033] This type of integrated ring cage has a left and right side structure that is tightly connected to the bottom / top cover via slide rails. The front and rear side structures are inserted into the sixth opening of the left side plate and the seventh opening of the second side plate to form a six-sided rigid box, which improves the overall structural stability.

[0062] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0063] Please see Figures 1-19 A complete ring network enclosure integrating primary and secondary components, including:

[0064] The bottom structure 200 is used to support several power cabinets, which have six sides: top, bottom, left, right, front, and back.

[0065] The top cover 100 can shield the upper side of several electrical cabinets;

[0066] The right-side structure 300 can shield the right side of several power cabinets;

[0067] The rear structure 400 can shield the rear of several power cabinets, and the rear structure 400 can also be opened for maintenance of the rear of the power cabinets.

[0068] The front structure 500 can block the front of several power cabinets, and the front structure 500 can also be opened for front inspection of the power cabinets.

[0069] The left structure 600 can block the left side of several power cabinets, and both the right structure 300 and the left structure 600 can be folded to the bottom of the top cover 100.

[0070] Specifically, during manufacturing, the bottom structure 200, top cover 100, right side structure 300, rear side structure 400, front side structure 500, and left side structure 600 can all be produced separately. When it is necessary to move them to the installation point for installation, the bottom structure 200, top cover 100, right side structure 300, rear side structure 400, front side structure 500, and left side structure 600 can be placed separately in the cargo compartment of the transport vehicle.

[0071] Upon reaching the installation point, simply install and fix the bottom structure 200 on the ground, then install several power cabinets on the bottom structure 200. Next, stand the right structure 300 and left structure 600, which are folded at the bottom of the top cover 100, upright, and install the bottoms of the right structure 300 and left structure 600 on the right and left sides of the bottom structure 200, respectively. Since the right structure 300 and left structure 600 are installed, the top cover 100 located above the right structure 300 and left structure 600 will also be initially fixed.

[0072] Then, the rear structure 400 and the front structure 500 are inserted into the bottom structure 200 from the side closest to the right structure 300, respectively, so that the rear structure 400 and the front structure 500 are installed on the rear and front sides of the bottom structure 200, forming a "six-sided box" together with the bottom structure 200, the top cover 100, the right structure 300, and the left structure 600 (e.g., Figure 1 and Figure 2 As shown in the figure, the previously installed power cabinets are all located inside this six-sided box. By means of the above method, it is possible to transport the equipment without pre-assembly, without taking up transport space, without causing collisions with surrounding items due to its large size, and without being easily hit by surrounding objects.

[0073] Furthermore, in order for the bottom structure 200 to support the power cabinet, as a preferred embodiment of the present invention, please refer to... Figures 1-4 and Figure 6 The bottom structure 200 includes a base plate 210, two first slide rails 220 and two second slide rails 230. The bottom surfaces of the two first slide rails 220 and the two second slide rails 230 are fixedly connected to the upper surface of the base plate 210. The two first slide rails 220 are located on the front and rear sides of the base plate 210, and the two second slide rails 230 are located on the left and right sides of the base plate 210, respectively. The two first slide rails 220 and the two second slide rails 230 are connected to the right side structure 300, the rear side structure 400, the front side structure 500 and the left side structure 600, respectively.

[0074] Specifically, by setting up a base plate 210 (which has support columns at the bottom to raise the height of the base plate 210 and reduce the probability of rainwater entering the interior of the base plate 210 during rainy or snowy weather), during installation, the power cabinets are all connected to the base plate 210 by fasteners such as bolts or flanges to prevent the power cabinets from falling to the ground.

[0075] By setting the first slide rail 220 and the second slide rail 230, a connection point can be added to the base plate 210 with the right side structure 300, the rear side structure 400, the front side structure 500, and the left side structure 600.

[0076] Furthermore, in order for the top cover 100 to shield the upper side of several power cabinets, as a preferred embodiment of the present invention, please refer to [reference needed]. Figures 1-4 The top of the cover 100 has a "double slope" structure, which can better drain water and prevent rain and snow from accumulating and collapsing the cover 100. In addition, the cover 100 can also be made of a high corrosion-resistant and strong material (such as stainless steel) to ensure the strength and service life of the cover 100 itself.

[0077] Furthermore, in order for the right-side structure 300 to block the right side of several power cabinets, as a preferred embodiment of the present invention, please refer to [reference needed]. Figure 1 , Figure 4 , Figure 6 , Figure 7 , Figures 9-11 The right side structure 300 includes a right side plate 310, a first plate 320, and a first rod 330. The bottom surface of the right side plate 310 is provided with a second sliding groove 311. The second sliding groove 311 is slidably connected to a second sliding rail 230 located on the right side of the bottom plate 210. One end of the right side plate 310 away from the second sliding groove 311 is fixedly connected to both ends of the first rod 330. The middle part of the first rod 330 is rotatably connected to one end of the first plate 320 through a first bearing. The other end of the first plate 320 is fixedly connected to one end of the top cover 100. The right side plate 310 is connected to the rear side structure 400 and the front side structure 500 through the right side limiting component 800.

[0078] Specifically, by setting a right side plate 310 with a second sliding groove 311 at the bottom, the right side plate 310 can be tightly connected to the bottom plate 210. Secondly, the height and width of the right side plate 310 can form a "baffle" on the right side of the power cabinet, which can shield the power cabinet and protect it from impact.

[0079] By setting the first plate 320 and the first rod 330, the right side plate 310 and the top cover 100 can be connected, so that there is a stable connection between the right side plate 310 and the top cover 100.

[0080] The principle of the right structure 300 is as follows: During the transfer stage, since the right side plate 310 and the top cover 100 are rotatably connected by the first rod 330 and the first bearing, the right side plate 310 can be folded under the top cover 100, thereby saving the space occupied by the height of the right side plate 310.

[0081] During installation, align the second slide groove 311 of the right side plate 310 with the second slide rail 230 located on the right side of the base plate 210 and insert it (the second slide rail 230 and the second slide groove 311 have the same shape and both have a trapezoidal cross-section, such as...). Figure 5 As shown in the figure, after the lower end of the right side plate 310 is restricted by the second slide rail 230 and the second slide groove 311, the top cover 100 located at the upper end of the right side plate 310 can also be initially fixed.

[0082] Furthermore, in order for the rear structure 400 to shield the rear of several power cabinets, and for the rear structure 400 to be openable for rear-side maintenance of the power cabinets, as a preferred embodiment of the present invention, please refer to [reference needed]. Figures 2-4 , Figure 7 , Figures 9-11 The left side structure 600 includes a left side plate 610, a second plate 620, and a second rod 630. The bottom surface of the left side plate 610 is provided with a fifth sliding groove 611, which is slidably connected to the second slide rail 230 on the left side of the bottom plate 210. The end of the left side plate 610 away from the fifth sliding groove 611 is fixedly connected to both ends of the second rod 630. The middle part of the second rod 630 is rotatably connected to one end of the second plate 620 through a second bearing. The other end of the second plate 620 is fixedly connected to the end of the top cover 100 away from the first plate 320. The height of the second plate 620 is longer than the height of the first plate 320, and the height is not less than the thickness of the second plate 620. The left side plate 610 is connected to the rear side structure 400 and the front side structure 500 through the left side limiting component 800.

[0083] Specifically, by setting a left side plate 610 with a fifth sliding groove 611 at the bottom, its function is the same as that of the right side plate 310, the difference being that the left side plate 610 is located on the left side of the bottom plate 210;

[0084] By setting the second plate 620 and the second rod 630, the two have the same function as the first plate 320 and the first rod 330, which is to connect the left plate 610 and the top cover 100, so that there is a stable connection between the left plate 610 and the top cover 100.

[0085] The principle of the left structure 600 is as follows: During the transfer stage, since the height of the second plate 620 is longer than the height of the first plate 320, and the height of the second plate 620 is not less than the thickness of the second plate 620, although the left plate 610 is also folded under the top cover 100, the left plate 610 is also located under the right plate 310. That is, from top to bottom: top cover 100, right plate 310, left plate 610.

[0086] During the installation phase, since the right side plate 310 is located between the top cover 100 and the left side plate 610, the left side plate 610 needs to be erected before the right side plate 310 is erected. Then, the fifth slide groove 611 of the left side plate 610 is aligned with the second slide rail 230 on the left side of the bottom plate 210 and inserted. (If there are two or more workers, the connection between the left side plate 610 and the second slide rail 230 and the connection between the right side plate 310 and the second slide rail 230 can be done simultaneously. If there is only one worker, the left side plate 610 can be installed first and then the right side plate 310 can be installed. There is no specific limitation.) After the left side plate 610 and the right side plate 310 are installed on the second slide rail 230, the top cover 100 will be relatively fixed due to the support of the left side plate 610 and the right side plate 310. (Although the top cover 100 may tilt due to the first rod 330, the first bearing, the second rod 630, and the second bearing, it does not affect the fact that the top cover 100 is already above the left side plate 610 and the right side plate 310.)

[0087] Furthermore, in order for the front structure 500 to block the front of several power cabinets, and for the front structure 500 to be openable for front-side maintenance of the power cabinets, as a preferred embodiment of the present invention, please refer to [reference needed]. Figures 1-4 , Figure 7 , Figures 9-11The front structure 500 includes a front frame 510, a front door 520, a front second door 530, a fourth slide rail 540, and at least two second limiting rods 550. A fourth slide groove 511 is formed on the bottom surface of the front frame 510. The fourth slide groove 511 is slidably connected to a first slide rail 220 located on the front side of the base plate 210. One end of the front frame 510 away from the fourth slide groove 511 is fixedly connected to one side of the fourth slide rail 540. The fourth slide rail 540 is slidably connected to a first slide groove 101 located on the front side of the top cover 100. The upper and lower sides of the front door 520 and the front second door 530, which are away from each other, are connected to the front frame via fourth bearings. 510 is rotatably connected. The front door 520 and the front second door 530 are each provided with a fourth opening 521 and a fifth opening 522 at one end away from each other. The fourth opening 521 and the fifth opening 522 are connected. The upper and lower ends of the two second limiting rods 550 are respectively fixedly connected to the upper and lower sides of the two fifth openings 522. The second limiting rods 550 are coaxial with the fourth bearing. The front frame 510 is provided with an eighth opening on the side near the two fifth openings 522, which is connected to the fourth opening 521. The left side plate 610 and the right side plate 310 are connected to the second limiting rods 550, the eighth opening and the fourth opening 521 through the limiting assembly 800.

[0088] Specifically, by providing a front frame 510 with a fourth slide groove 511 and an eighth opening, the front frame 510 can be connected to the base plate 210 through the fourth slide groove 511, and the front frame 510 can also be connected to the limiting component 800 through the eighth opening. This ensures that the connection between the front frame 510 and the base plate 210 is stable, while also ensuring that the front frame 510 is restricted by the limiting component 800 and will not become loose during use.

[0089] By setting the first door 520 and the second door 530, the center opening (which can also be understood as the maintenance opening or entrance) of the front frame 510 can be blocked during non-maintenance periods. Secondly, the center opening of the front frame 510 can be exposed during maintenance, so as not to affect maintenance personnel. In addition, since the first door 520 and the second door 530 are each provided with a fourth opening 521 and a fifth opening 522, the first door 520 and the second door 530 can be limited by the limiting component 800 after they are opened, so as to prevent the first door 520 and the second door 530 from closing by themselves during maintenance.

[0090] By setting the fourth slide rail 540, the front frame 510 can be connected to the top cover 100;

[0091] By setting a second limiting rod 550 [its cross-sectional shape on the first surface (the first surface is parallel to the top cover 100), such as...] Figure 17 and Figure 18The limit component 800 can be provided with a connection point to limit the front door 520 and the front second door 530 (the specific limiting method is explained in detail in the limit component 800 section below).

[0092] The principle of the front structure 500 is as follows: During the transfer stage, the front structure 500 is a whole unit and is not connected to the bottom structure 200, top cover 100, right side structure 300, rear structure 400 and left side structure 600. Therefore, it can be placed separately (e.g., laid flat) for transfer, thereby reducing the external space occupied.

[0093] During the installation phase, the front frame 510 is inserted from the right side of the base plate 210, and the fourth slide groove 511 of the front frame 510 is inserted into the outside of the first slide rail 220 on the front side of the base plate 210. At the same time, the fourth slide rail 540 of the front frame 510 is aligned with the first slide groove 101 on the front side of the top cover 100 and inserted, so that the front frame 510 can be stably connected to the base plate 210 and the top cover 100 in one go.

[0094] Furthermore, in order for the left-side structure 600 to block the left side of several power cabinets, as a preferred embodiment of the present invention, please refer to... Figures 1-4 , Figure 7 , Figures 9-11 The rear structure 400 includes a rear frame 410, a rear door 420, a rear second door 430, a third slide rail 450, and at least two first limiting rods 440. The top cover 100 has two first sliding grooves 101 on the side near the bottom structure 200, located on the front and rear sides of the top cover 100 respectively. The bottom surface of the rear frame 410 has a third sliding groove 411, which is slidably connected to the first slide rail 220 located behind the bottom plate 210. The end of the rear frame 410 away from the third sliding groove 411 is fixedly connected to one side of the third slide rail 450. The third slide rail 450 is slidably connected to the first sliding groove 101 located behind the top cover 100. The rear door 420 and the rear second door 430... The upper and lower sides of the door 430 at the opposite ends are rotatably connected to the rear frame 410 through the third bearing. The rear door 420 and the rear second door 430 at the opposite ends are provided with a second opening 431 and a third opening 432, which are connected to each other. The upper and lower ends of the two first limiting rods 440 are fixedly connected to the upper and lower sides of the two third openings 432 respectively, and the first limiting rods 440 are coaxial with the third bearing. The rear frame 410 at the side near the two second openings 431 is provided with a first opening 412 that is connected to the second opening 431. The left side plate 610 and the right side plate 310 are connected to the first limiting rods 440, the first opening 412 and the second opening 431 through the limiting assembly 800.

[0095] Specifically, by setting a rear frame 410 with a third slide groove 411 and a first opening 412, the function of the rear frame 410 is the same as that of the front frame 510, and the functions of the third slide groove 411 and the first opening 412 are the same as those of the fourth slide groove 511 and the eighth opening, which will not be explained in detail here.

[0096] By setting up the rear door 420 and the rear second door 430, the functions of the rear door 420 and the rear second door 430 are the same as those of the front door 520 and the front second door 530; and the functions of the second opening 431 and the third opening 432 on the rear door 420 and the rear second door 430 are the same as those of the fourth opening 521 and the fifth opening 522, which will not be explained in detail here.

[0097] By setting the third slide rail 450, its function is the same as that of the fourth slide rail 540, which will not be explained in detail here;

[0098] The first limiting rod 440 has the same function as the second limiting rod 550, and will not be described in detail here.

[0099] Furthermore, in order to make the front frame 510 and the rear frame 410 more stable when connected between the base plate 210 and the top cover 100, as a preferred embodiment of the present invention, please refer to... Figures 7-11 The left side plate 610 has two sixth openings 612 on the side near the right side plate 310, and the second plate 620 has seven openings 621 at both ends. The two sixth openings 612 are aligned with the two seventh openings 621 respectively, and the aligned sixth openings 612 and seventh openings 621 form a group. The rear frame 410 and the front frame 510 are slidably connected to the two groups of sixth openings 612 and seventh openings 621 on the side away from the right side plate 310 respectively.

[0100] The principle of the rear structure 400 is as follows: During the transfer stage, since it is the same as the front structure 500, the rear structure 400 is a whole and is not connected to the bottom structure 200, top cover 100, right side structure 300, front structure 500 and left side structure 600, etc. Therefore, it can be placed separately (e.g., laid flat) for transfer, thereby reducing the external space occupied.

[0101] During installation, first align the third slide groove 411 of the rear frame 410 with the first slide rail 220 on the rear side of the base plate 210, and at the same time align the third slide rail 450 with the first slide groove 101 on the rear side of the top cover 100. Then, insert the rear frame 410 between the top cover 100 and the base plate 210 from the direction of the right side plate 310. After that, push the rear frame 410 (the same steps are used for the front frame 510) so that the rear frame 410 abuts against the aligned sixth opening 612 and seventh opening 621, which can further improve the connection stability between the rear frame 410 and the front frame 510 and the left side plate 610, and the whole process is convenient, quick and easy to operate.

[0102] Furthermore, the integrated ring cage, in addition to including the bottom structure 200, top cover 100, right side structure 300, rear structure 400, front structure 500, and left side structure 600, also includes at least four limiting components 800. The limiting components 800 can simultaneously fix the unfolded and closed states of the rear structure 400 and the front structure 500. The limiting components 800 are evenly divided into two groups, and the two groups of limiting components 800 are located on the left and right sides of the bottom structure 200, respectively.

[0103] In order for the limiting component 800 to simultaneously fix the unfolded and closed states of the rear structure 400 and the front structure 500, as a preferred embodiment of the present invention, please refer to... Figure 13 and Figure 14 The limiting assembly 800 includes a connecting piece 810, a spring 820, a support plate 830, an outer limiting member 840, an inner limiting member 850, and a guide rod 860. The outer limiting member 840 has a moving cavity 841 inside. One end of the inner limiting member 850 is located in the moving cavity 841. The end of the support plate 830 is connected to the power mechanism 700. One side of the middle of the support plate 830 is fixedly connected to one end of the spring 820. The other end of the spring 820 is fixedly connected to one side of the connecting piece 810. The other side of the connecting piece 810 is connected to the power mechanism 700. The middle part of the connecting piece 810 near the spring 820 is fixedly connected to one end of the guide rod 860. The other end of the guide rod 860 passes through the spring 820 and the support plate 830 into the moving cavity 841 and is connected to the inner limiting member 850. The other end of the inner limiting member 850 is connected to the first limiting rod 440 or the second limiting rod 550.

[0104] Specifically, by setting the connecting piece 810, the spring 820 can be supported at the end away from the support plate 830 to prevent it from collapsing or falling off; secondly, the connecting piece 810 can also stabilize the power of the power mechanism 700 on the spring 820 and the guide rod 860.

[0105] By setting the spring 820, the guide rod 860 can be moved by its own elasticity, thereby pushing the inner limit member 850 through the other end, and also through the push plate in the middle of the guide rod 860 (such as... Figure 19 (As shown) Drive the outer limit component 840;

[0106] By setting the support plate 830, support and movement direction limitation can be provided for all components of the limiting assembly 800;

[0107] By setting an outer limiting member 840, the outer limiting member 840 can be inserted into the eighth opening of the front frame 510 and the first opening 412 of the rear frame 410 to restrict the movement of the front frame 510 and the rear frame 410; in addition, since the outer limiting member 840 has a moving cavity 841 inside, the inner limiting member 850 can also be housed in the moving cavity 841 without affecting the opening and closing limit of the rear door 420, the rear second door 430, the front door 520 and the front second door 530 by the inner limiting member 850.

[0108] By setting the guide rod 860, it can be ensured that the outer limit member 840 and the inner limit member 850 can only move in a specific direction, and will not tilt or fall off.

[0109] By setting the inner limit component 850, the opening and closing of the rear door 420, the rear second door 430, the front door 520, and the front second door 530 can be limited.

[0110] In order for the inner limiting member 850 to limit the opening and closing of the rear door 420, the second rear door 430, the first front door 520, and the second front door 530, as a preferred embodiment of the present invention, please refer to [the following text is missing from the original extract]. Figure 13 and Figure 14 The inner limiting member 850 of the limiting assembly 800 connected to the front structure 500 includes only an inner block 851. The inner limiting member 850 of the limiting assembly 800 connected to the rear structure 400 includes an inner block 851, a first limiting block 852, and a second limiting block 853. One end of the guide rod 860 located in the moving cavity 841 is fixedly connected to the side wall of the inner block 851. The outer wall of the inner block 851 is slidably connected to the moving cavity 841. A cavity is opened at the end of the inner block 851 away from the guide rod 860. The first limiting rod 440 and the second limiting rod 550 are respectively located in the cavities of the two inner blocks 851. One end of the first limiting block 852 and the second limiting block 853 are both fixedly connected to the cavity of the inner block 851.

[0111] Specifically, by setting an inner block 851 with a cavity, such as Figures 15-18 As shown, where Figure 15 and Figure 16 The rear structure 400 has two modes: the rear door 420 and the rear second door 430, and the inner limiting member 850, which can be closed or open; among them Figure 17 and Figure 18 The front door 520 and the second front door 530 of the front side structure 500 have two modes of being closed and open with the inner limiting member 850.

[0112] By setting the second limit block 853 (e.g.) Figure 15 and Figure 16In both the closed and open states of the rear door 420 and the rear second door 430, the rotation of the inner block 851 can be restricted without external force driving the movement of the inner block 851.

[0113] By setting the first limit block 852 (e.g.) Figure 15 and Figure 16 When the second limiting block 853 moves away from the inner block 851 and disengages from the first limiting rod 440, the second limiting block 853 can push the first limiting rod 440 from behind, causing the first limiting rod 440 to rotate at a small angle. This allows the rear door 420 and the rear second door 430 to open slightly, preventing them from closing automatically when maintenance personnel go to the rear of the six-sided enclosure.

[0114] In addition, such as Figures 15-18 As shown, the surfaces of the first limiting rod 440 and the second limiting rod 550, which cooperate with the inner limiting member 850, are provided with a first limiting opening 441, a second limiting opening 442, and a ramp 443. The first limiting opening 441 and the second limiting opening 442 of the first limiting rod 440 abut against the second limiting block 853, and the ramp 443 abuts against the first limiting block 852. The first limiting opening 441, the second limiting opening 442, and the ramp 443 of the second limiting rod 550 abut against the cavity wall of the inner block 851.

[0115] Specifically, by providing a first limiting opening 441, a second limiting opening 442, and a ramp 443 on the surfaces of the first limiting rod 440 and the second limiting rod 550, the inner limiting member 850 can be used to limit the rear door 420 and the rear second door 430 (or the front door 520 and the front second door 530).

[0116] Furthermore, as a preferred embodiment of the present invention, the cross section of the outer limiting member 840 on the first surface is a right trapezoid, the first surface is parallel to the top cover 100, and the inclined surfaces of the right trapezoids of the outer limiting member 840 on the right side plate 310 and the left side plate 610 are both facing the right side plate 310, and the width of the outer limiting member 840 near the right side plate 310 is greater than the width of the outer limiting member 840 near the left side plate 610;

[0117] Specifically, by setting the cross-section of the outer limiting member 840 to a right trapezoid, with the inclined surface of the right trapezoid facing the right side plate 310, the front frame 510 and the rear frame 410 can be inserted from the direction of the right side plate 310, and the pushing force of the front frame 510 and the rear frame 410 moving themselves can automatically push the outer limiting member 840 back (compression spring 820), without the need for the staff to loosen the limiting component 800, which is more convenient and improves the installation efficiency.

[0118] Furthermore, because the width of the outer limiting member 840 near the right side panel 310 is smaller than the width of the outer limiting member 840 near the left side panel 610, when the front frame 510 and the rear frame 410 are inserted from the direction of the right side panel 310, the width of the outer limiting member 840 on the right side panel 310 is larger. Therefore, when the front frame 510 and the rear frame 410 pass the right side panel 310, because the size of the first opening 412 on the left side of the front frame 510 and the rear frame 410 is smaller than the outer limiting member 840 on the right side panel 310, the outer limiting member 840 cannot be inserted into the first opening 412. When the front frame 510 and the rear frame 410 move into the sixth opening 612 of the left side panel 610, the outer limiting member 840 on the right side of the front frame 510 and the rear frame 410 is inserted into the adjacent first opening 412. Similarly, the outer limiting member 840 on the left side of the front frame 510 and the rear frame 410 is inserted into the adjacent first opening 412.

[0119] The principle of the limiting component 800 is as follows: Before the front frame 510 and the rear frame 410 are inserted into the sixth opening 612 from the direction of the right side plate 310, the frame of the front frame 510 and the rear frame 410 will squeeze the inclined surface of the right trapezoid of the outer limiting component 840. At this time, the outer limiting component 840 is squeezed towards the spring 820 and the spring 820 is compressed at the same time.

[0120] Then, the front frame 510 and the rear frame 410 continue to move. When the front frame 510 and the rear frame 410 are inserted into the sixth opening 612, the outer limiting member 840 is aligned with the fourth opening 521 and the second opening 431. At this time, the spring 820 restores its elasticity, which pushes the outer limiting member 840 into the fourth opening 521 and the second opening 431. At the same time, the second limiting block 853, which is close to the inner block 851 of the rear door 420, is inserted into the second limiting opening 442 of the first limiting rod 440 (e.g., Figure 15 As shown), at this time, the first limiting rod 440 and the second limiting port 442, together with the inner block 851 and the third port 432, can restrict the opening of the rear door 420 and the rear second door 430. Similarly, when the front frame 510 is inserted into the sixth port 612, the inner block 851 near the front frame 510 abuts against the side wall of the front door 520 (as shown). Figure 18 As shown), the inner block 851 of the front frame 510 will not obstruct the normal opening of the first door 520 and the second door 530. Therefore, the first door 520 and the second door 530 can be locked normally by the key lock, which is convenient for maintenance personnel to open directly with the key.

[0121] When maintenance is required, maintenance personnel can directly open the first front door 520 and the second front door 530 using a key. At this time, the first front door 520 and the second front door 530 are... Figure 18 Transfer to Figure 17At this time, the inner block 851 near the first door 520 and the second door 530 is automatically pushed into the fifth opening 522 of the first door 520 and the second door 530 under the action of the spring 820, thereby limiting the first door 520 and the second door 530 through the second limit rod 550 and the inner block 851, preventing the first door 520 and the second door 530 from closing by themselves;

[0122] If maintenance is required at the rear of the six-sided enclosure, the maintenance personnel pull the guide rod 860. The guide rod 860, under pressure, moves the connecting piece 810 and the inner block 851 near the rear door 420. During the movement of the inner block 851 into the moving cavity 841 of the outer limiting member 840, the second limiting block 853 is pulled out from the second limiting port 442 of the first limiting rod 440 (see details). Figure 15 and Figure 16 Afterwards, the inner block 851 continues to move, and the second limiting block 853 completely disengages from the second limiting port 442. Then, the first limiting block 852 abuts against the ramp 443 of the first limiting rod 440, thereby pushing the ramp 443 to rotate slightly. Afterwards, the inner block 851 continues to move, and the first limiting block 852 disengages from the first limiting rod 440. Since the first limiting rod 440 is coaxial with the bearing of the rear door 420 (or the rear second door 430), the rear door 420 (or the rear second door 430) will also open slightly. Then, the guide rod 860 is released, and the spring 820 pushes the inner block 851, the first limiting block 852, and the second limiting block 853 back to their original positions. The second limiting block 853 will then abut against the ramp 443 of the first limiting rod 440, at which point the first limiting rod 440 can be pushed to... Figure 16 The state is such that the second limiting block 853 is located within the first limiting port 441, so as to continue to limit the rear door 420 (or the rear second door 430), so that the rear door 420 (or the rear second door 430) cannot close by itself.

[0123] Furthermore, the integrated ring cage, in addition to including a bottom structure 200, a top cover 100, a right side structure 300, a rear side structure 400, a front side structure 500, a left side structure 600 and a limiting component 800, also includes at least two power mechanisms 700. The power mechanism 700 can drive the limiting component 800 to simultaneously release the fixation of the rear side structure 400 and the front side structure 500, and the power mechanism 700 can also drive the rear side structure 400 to close while releasing the fixation of the rear side structure 400.

[0124] To enable the power mechanism 700 to achieve the aforementioned objectives, the power mechanism 700 includes a protective cover 710, a knob 720, a first rope 730, a third rod 740, a partition 750, and at least two second ropes 760. Both ends of the support plate 830 are fixedly connected to the inner wall of the protective cover 710. One side of the protective cover 710 is fixedly connected to either the right side plate 310 or the left side plate 610. The two ends of the third rod 740 are located inside and outside the protective cover 710, respectively. The third rod 740 is rotatably connected to the connecting post of the protective cover 710 via a fifth bearing, and the third rod 740 is located inside the protective cover 710. One end of the second rope 760 is fixedly connected to the inner wall of the partition 750. One end of each of the two second ropes 760 is fixedly connected to the end of the third rod 740 located inside the protective cover 710. The other ends of the two second ropes 760 are fixedly connected to the two connecting pieces 810 respectively. The two second ropes 760 are wound in opposite directions on the third rod 740. One end of the third rod 740 located outside the protective cover 710 is fixedly connected to both the knob 720 and the first rope 730. The other end of the first rope 730 is fixedly connected to the rear door 420 or the rear second door 430. The two second ropes 760 are located on both sides of the partition 750 respectively.

[0125] Specifically, by setting up a protective cover 710, the limiting component 800 can be protected and shielded, while improving the overall aesthetics;

[0126] By setting knob 720, the third lever 740 can be rotated more conveniently;

[0127] By setting the first rope 730, when the limit component 800 is released from the limit on the first rear door 420 and the second rear door 430, the first rope 730 can automatically close the first rear door 420 and the second rear door 430, without the need for staff to go to the back of the six-sided box, which is convenient and saves time.

[0128] By setting the third rod 740, the first rope 730 and the second rope 760 can be wound together, thereby increasing the pulling force of the first door 420, the second door 430, and the connecting piece 810;

[0129] By setting the partition 750, the two second ropes 760 can be separated;

[0130] By setting the second rope 760, the rotational force of the knob 720 can be converted into a pulling force, thereby pulling the connecting piece 810 to move laterally;

[0131] The principle of the power mechanism 700 is as follows: When it is necessary to release the limiting component 800 from the front door 520, the second front door 530, the first rear door 420, and the second rear door 430, simply turn the knob 720. The rotation of the knob 720 causes the third rod 740 to rotate. The rotation of the third rod 740 will gradually wrap the two second ropes 760 around the surface of the third rod 740. Then, the connecting piece 810 can be pulled by the wrapped second ropes 760, thereby pulling the inner block 851 back into the moving cavity 841 of the outer limiting component 840. (If it is necessary to completely disassemble the six-sided box, simply continue to pull the connecting piece 810, and the inner block 851 will push the outer limiting component 840 back into the protective cover 710. Then, the front frame 510 and the rear frame 410 can be pulled out from the direction of the right side plate 310.)

[0132] After releasing the outer limiters 840 from the limits of the front door 520, the second front door 530, the first rear door 420, and the second rear door 430, the maintenance personnel can additionally pull the first rope 730 to pull the first rear door 420 and the second rear door 430 towards the base plate 210 until the first rear door 420 and the second rear door 430 are completely closed. Then, by turning the knob 720, the inner block 851 will continue to push out due to the action of the spring 820, returning to its original position. Figure 15 and Figure 18 The state.

[0133] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
