The single ring main unit includes an outer casing 200 and an inner accommodating space M formed by the casing 200 , and the monitoring unit 100 is located in the accommodating space M. Each ring main unit is measured through its own monitoring module 102 to obtain its own monitoring data, and through its respective control module 101 instructs the corresponding prompt module 103 to work. The same as a single ring network cabinet is that the monitoring data of multiple ring network cabinets and their comparison results with the corresponding thresholds are sent to the server 105 through the respective transceiver modules 104 in a centralized manner, and can be sent to the server 105 by the intelligent terminal 106 to access.

Further, the housing 200 includes a first side plate 201 and a second side plate 202, which are parallel to each other. The housing 200 also includes a rear side panel 203 , a top panel 204 and a bottom panel 205 . The first side plate 201 and the second side plate 202 are connected to the rear side of the cabinet through the rear side plate 203 , the top surface of the cabinet through the top plate 204 , and the bottom surface of the cabinet through the bottom plate 205 .

It can be seen from the above that there is at least one single ring network cabinet in the present invention, and when there is only one single ring network cabinet, it is used as a separate ring network cabinet; as shown in Figures 3 to 5, when the single ring network cabinet is When there are more than two, the individual ring network cabinets are connected to each other through the connecting unit 400 to form a row, and together form the modular ring network cabinet.

In the present invention, the connecting unit 400 has the function of connecting each group of ring main units adjacent to each other. The two adjacent ring main units of each group are combined under the connection of the plurality of connection units 400 . The connection unit 400 includes a pulling module 401 and a matching module 402, wherein the pulling module 401 is a linkage structure used to connect the single edge of the ring network cabinet, and the matching module 402 is used to pull the single edge ring network cabinet. Pull the module 401 to cooperate with the hook body. Since multiple ring main units have the same structure and can be connected in sequence after being arranged arbitrarily, in order to ensure orderliness, each ring main unit includes a plurality of connection units 400, among which the pulling module 401 and the The number of the matching modules 402 is the same and corresponds to each other one by one.

Specifically, the pulling module 401 is arranged at the top edge and the bottom edge of the front and rear sides of each ring main unit unit, and is uniformly fixed to one edge of the front side (or rear side), while the matching module 402 Relative to the pulling module 401 , it is disposed at the edge of the other side of the ring main unit, and forms a one-to-one correspondence with each pulling module 401 . That is, each ring main unit has multiple groups of pulling modules 401 and matching modules 402, and its own pulling module 401 is used to connect with the matching module 402 of the ring main unit on one side of the ring main unit, while its own pulling module 401 The matching module 402 is used to connect with the pulling module 401 of the ring main unit on the other side.

6-8, the pulling module 401 includes a base member 401a, a driving member 401b and a driven member 401c. The base member 401a may be a fixed hinge support, and the pulling module 401 is integrally fixed to the top and bottom edges of the ring main unit (both front and rear sides) through the base member 401a. The driving member 401b is rod-shaped, one end of which is hinged with the base member 401a to form the first hinge point J-1, and the other end is the operating end 401b-1, which is used for the external driving action point. One end of the driven member 401c is hinged on the driving member 401b (the two ends of the non-driving member 401b) to form the second hinge point J-2, and the other end is the connecting end 401c-1, which is used to connect with the edge ring main unit. It can hook the matching module 402 on the single side of the ring main unit. When the operating end 401b-1 is pushed clockwise, it can connect two adjacent ring main units. , the "clockwise" in the present invention is based on the overall top view of the modular ring main unit as a reference.

In the present invention, the matching module 402 is a hook-like structure, and the follower 401c may be a frame structure with a rounded rectangle in outline, and the rounded rectangle is on a vertical plane. The inner end of the follower 401c is hinged with the non-end position of the driving member 401b (such as the middle position of the driving member 401b or the position left and right in the middle), and the outer end is hooked on the edge through its own frame. on the mating module 402.

Preferably, the connecting end 401c-1 of the follower 401c is covered with a ring of deformation layer 401c-2, and the deformation layer 401c-2 is made of a tough material capable of being deformed under pressure, such as a rubber layer. When the matching module 402 hooks the connecting end 401c-1 and pushes the operating end 401b-1 of the driving member 401b clockwise at the same time, the deformation layer 401c-2 can squeeze with the matching module 402 and deform.

Further, the pulling module 401 further includes an elastic fitting 401d. In addition, the driving member 401b has a first fixing buckle 401b-2, and the driven member 401c has a second fixing buckle 401c-3. The driving member 401b is divided into a first section D-1 and a second section D-2 by the second hinge point J-2, wherein the section between the first hinge point J-1 and the second hinge point J-2 The first section D-1, the section between the second hinge point J-2 and the end of the operating end 401b-1 is the second section D-2. In the present invention, the first fixing buckle 401b-2 is arranged on the second section D-2, so the distance between the first fixing buckle 401b-2 and the first hinge point J-1 is greater than the second hinge point J- 2 is the distance from the first hinge point J-1. The second fixing buckle 401c-3 is fixed at a non-end position on the follower 401c. One end of the elastic adapter 401d is fixed on the first fixing buckle 401b-2, and the other end is fixed on the second fixing buckle 401c-3. In the process of driving the pulling module 401 to move as a whole through the driving member 401b, the elastic adapter member 401d can perform corresponding displacement adaptively and unimpeded. In the present invention, the first section D-1 of the driving member 401b, and the Part of the second section D-2 is a hollow structure in the middle, so as to allow the elastic adapter 401d to perform corresponding movement in the "hollow structure". The first fixing buckle 401b-2 is a short column structure fixed between two hollow sandwich layers of the driving member 401b; the second fixing buckle 401c-3 is a short column structure fixed between the upper and lower parallel frames of the driven member 401c.

The locking process of the connection unit 400 is as follows:

The connecting end 401c-1 of the follower 401c is hooked on the mating module 402 of the single side ring main unit (only for contact at this time, without pressing), and then push the operating end 401b-1 clockwise until When the deformation layer 401c-2 begins to be deformed under pressure, the horizontal angle between the driving member 401b and the driven member 401c is less than 180°. If the operating end 401b-1 continues to be pushed clockwise, the required thrust will gradually increase, and the pulling force received by the follower 401c itself will also increase accordingly. The deformation space of the deformation layer 401c-2 and the follower 401c itself makes the operating 401b-1 was able to proceed. During this process, the elastic adapter 401d is also gradually elongated.

When the operating end 401b-1 continues to be pushed clockwise until the three points of the first hinge point J-1, the second hinge point J-2 and the deformation layer 401c-2 are collinear, the pulling force received by the follower 401c reaches the maximum value (The deformation degree of the deformation layer 401c-2 also reaches the maximum). At this time, the elastic adapter 401d is also pulled to the longest. If the operating end 401b-1 continues to be pushed clockwise, in the subsequent process, the follower 401c gradually returns to its normal state, the pulling force is released, the deformation degree of the deformation layer 401c-2 also decreases, and the required driving force decreases sharply , even the operation end 401b-1 automatically rotates clockwise when the follower 401c and the deformation layer 401c-2 return to normal, until the operation end 401b-1 touches the surface of the housing 200 and cannot continue to rotate. At this time, the connection unit 400 is in a locked state as a whole, and the driving member 401b cannot rotate counterclockwise by itself (because it will be subjected to greater tension) unless it is driven counterclockwise from the outside. In the locked state, the horizontal angle between the driving member 401b and the driven member 401c is greater than 180°. Preferably, the elastic adaptor 401d at this time can pull the driving member 401b and the driven member 401c, which has the function of preventing loosening and rotation.

Further, the connection unit 400 further includes a safety module 403, the safety module 403 is hook-shaped, and the outer surface of the safety module 403 is a convex curved surface.

The operating end 401b-1 may be cylindrical, and has a hollow first chamber 401b-11 and a second chamber 401b-12 inside. The first chamber 401b-11 is located at the outer end of the second chamber 401b-12, and has a larger inner diameter than the second chamber 401b-12, forming a step shape at the junction of the two.

A telescopic piece 401b-13 is inserted into the first chamber 401b-11, and the telescopic piece 401b-13 is a columnar structure, the inner end of which is inserted into the second inner chamber 401b-12, and the outer end penetrates out of the first chamber 401b -11, the operation end 401b-1 is exposed to the outside (the outer end of the first chamber 401b-11 has a corresponding socket communicating with the outside world). In addition, the telescopic member 401b-13 has a limit ring 401b-14 located within the range of the first chamber 401b-11, and the limit ring 401b-14 is annular, which is larger than the outer end of the first chamber 401b-11. The maximum size of the socket is slightly smaller than the inner diameter of the first chamber 401b-11, so that the telescopic piece 401b-13 cannot be separated from the first chamber 401b-11. The first chamber 401b-11 also has a spring 401b-15. The spring 401b-15 is a compression spring, which is sleeved on the telescopic member 401b-13, one end abuts on the limit ring 401b-14, and the other end abuts on the first The inner end surface of the chamber 401b-11 (ie, the step surface formed by the first chamber 401b-11 and the second chamber 401b-12).

Therefore, when the operating end 401b-1 is pushed clockwise, the exposed part of the outer end of the telescopic piece 401b-13 can reach the safety module 403. Since the outer surface of the insurance module 403 is a convex curved surface, it can be adapted to slide along the convex curved surface, and at the same time, the retractable member 401b-13 retracts into the first chamber 401b-11 and the second chamber 401b-12.

Preferably, the outer end of the telescopic element 401b-13 is also set as a convex curved surface, and when the operation end 401b-1 is pushed clockwise, the convex curved surface of the telescopic element 401b-13 can be connected with the insurance module 403. The convex surfaces of the two contact each other to form extrusion, which is more conducive to the sliding between the two. When the outer end of the telescopic piece 401b-13 slides into the hook body along the convex curved surface of the insurance module 403, the telescopic piece 401b-13 rebounds and is exposed again, and the insurance module 403 can block it, further preventing it from loosening and returning Possibility of bombing.

Further, the operation end 401b-1 is bent relative to the first section D-1, and the bending direction is counterclockwise, so that the operation end 401b-1 has a larger clockwise rotation space, and the first A larger obtuse angle is obtained between segment D-1 and the follower 401c, reducing the structural instability of the follower 401c due to the possible tension still present.

As shown in FIGS. 9 to 13, the present invention also provides an embodiment, but different from the above: the top of the casing 200 is a top plate 204, the top plate 204 has a heat dissipation port 204a, and the upper part of the top plate 204 is also covered with a top cover 206. One side of the cover 206 is hinged with the edge of the top plate 204 , and the other side can be turned over to open or cover the cooling vent 204a.

The heat dissipation ports 204a in the above are through holes on the top plate 204, and a plurality of them can be arranged in an array for heat dissipation and ventilation. The arrangement of the top cover 206 can not only ensure the ventilation in the casing 200 selectively, but also can cover and close it to prevent the entry of dust or foreign objects when ventilation and heat dissipation are not required. One side of the top cover 206 and the edge of the top plate 204 may be connected by hinges, and in the present invention, multiple hinges may be provided.

In the present invention, the inversion of the top cover 206 is controlled by the top support unit 300, so as to realize the selective opening of the heat dissipation port 204a.

The top support unit 300 includes a rotating member 301 and an installation fixing plate 302 , and the rotating member 301 is fixed to the upper position of the inner side surface of the rear side plate 203 through the installation fixing plate 302 .

The rotating member 301 includes a connecting rod 301a and a top strut 301b. Among them, the connecting rod 301a has the function of a horizontal rotation axis, and its outer end passes through the mounting and fixing plate 302 and the rear side plate 203 in sequence, and extends to the outside of the casing 200, and the outer end of the connecting rod 301c is fixed with a driving part 301c, here The driving part 301c can be a rotating handle at the outer end of the connecting rod 301a, and the connecting rod 301a itself can be a round rod.

Further, the connecting rod 301a has a ring body 301a-1, and the ring body 301a-1 is located at the outer position of the mounting and fixing plate 302, and can “clamp” the mounting and fixing plate 302 together with the inner side of the top strut 301b, preventing contact The rod 301a is axially extended and slid on the mounting and fixing plate 302 in and out.

The inner end of the connecting rod 301a and the lower end of the top strut 301b are fixed perpendicular to each other, that is, the connecting rod 301a and the top strut 301b are perpendicular to each other and form an integrated structure. Therefore, by rotating the driving part 301c outside the casing 200, the top stay 301b can be rotated about the connecting rod 301a as an axis.

The top support rod 301b can be a straight rod, the lower end of which is fixed with the connecting rod 301a, and the upper end is used to lift up the top cover 206 to open it and open the heat dissipation port 204a. At the same time, the top plate 204 has an allowable slit 204b matched with the top strut 301b. The allowable slit 204b is a bar-shaped transparent slit. The lower surface of the cover 206 can follow the rotation of the connecting rod 301a to lift or lower the top cover 206 .

In the present invention, the mounting and fixing plate 302 may be plate-shaped, and is fixed to the inner side surface of the rear side plate 203 through the strips on both sides.

The mounting and fixing plate 302 has a first limiting column 302a and a second limiting column 302b, both of which are short-column structures vertically fixed on the mounting and fixing plate 302, and can block the rotation of the top strut 301b, The top strut 301b can only be rotated within the range between the two. specific:

When the top strut 301b rotates to the first limit post 302a, it cannot continue to rotate due to the obstruction of the first limit post 302a, and the upper end of the top strut 301b at this time can push up the top cover 206 to open the top cover 206 Heat dissipation port 204a; when the top strut 301b rotates to the second limit post 302b, it cannot continue to rotate due to the obstruction of the second limit post 302b, and the top strut 301b at this time can just put down the top cover 206, so that the top The cover 206 covers the heat dissipation port 204a.

Preferably, the top support unit 300 further includes an adapter rod 303, one end of the adapter rod 303 is hinged with the lower end of the top support rod 301b, and the other end is fixedly connected to the non-end position of the top support rod 301b through a tension spring 304. . Through the adaptability of the adapting rod 303 and the tension spring 304, the top support rod 301b can maintain a stable state no matter when the top cover 206 is lifted up or when the top cover 206 is put down, preventing external interference from causing the top The structure in which the cover 206 is "raised" lacks stability.

Specifically, the adapter rod 303 is a straight rod, which can rotate around the hinge point with the top support rod 301b, and its rotation also has a range limit, as follows:

The mounting and fixing plate 302 also has a third limiting column 302c and a fourth limiting column 302d, both of which can be short columns or block structures (block structures in the drawings of the present invention), and can be adapted to the adapter rod 303 Rotation is hindered.

If it is assumed that initially, the adapter rod 303 abuts against the fourth limit post 302d, and the top strut 301b abuts against the second limit rod 302b, set the adapter rod 303 and the top strut 301b at this time If the included angle between them is less than 180°, due to the stretching action of the tension spring 304, the adapting rod 303 and the top support rod 301b can form a stable structure and cannot be changed. At this time, the top end of the top support rod 301b does not have a top support function on the lower surface of the top cover 206 .

When the top strut 301b is rotated counterclockwise to the first limit post 302a, the angle between the adapter rod 303 and the top strut 301b gradually increases, and when it reaches 180°, an unstable structure is formed, and the adapter rod 303 has a tendency to rotate toward the third limit post 302c. If the top support rod 301b continues to be rotated counterclockwise, the adaptor rod 303 will be pulled by the tension spring 304 and rotated to the third limit post 302c, and the third limit post 302c prevents the adaptor rod 303 from continuing to rotate. When the support rod 301b finally rotates to the first limit post 302a, the included angle between the adapter rod 303 and the top support rod 301b is set to be greater than 180°, which still forms a stable structure, ensuring that the “supported” top cover 206 has stability.

Preferably, a matching groove 301b-1 is recessed on a side surface of the top support rod 301b corresponding to the first limit post 302a. When the strut 301b rotates to the first limiting column 302a, the matching groove 301b-1 can be just caught on the first limiting column 302a, which enhances the bonding force of the two and the stability of the overall structure.

If it is necessary to cover the cooling vent 204a, it is only necessary to rotate the top support rod 301b clockwise, and the angle between the adapter rod 303 and the top support rod 301b gradually decreases, and when it reaches 180°, an unstable structure is formed, and the adaption The rod 303 has a tendency to rotate toward the fourth limit post 302d. If the top support rod 301b continues to be rotated clockwise, the adaptor rod 303 will be pulled by the tension spring 304 to rotate to the fourth limit post 302d, and the fourth limit post 302d prevents the adaptor rod 303 from continuing to rotate. When the support rod 301b finally rotates to the second limit post 302b, and the angle between the adapter rod 303 and the top support rod 301b returns to the initial state, that is, less than 180°, the heat dissipation port 204a is covered and kept stable. structure.

When the user observes the light of the prompt module 103, or finds that the temperature in the cabinet reaches the warning level through the smart terminal 106, the top cover 206 can be propped up by the top support unit 300, and the heat dissipation port 204a can be cleared for ventilation and heat dissipation, so as to achieve the purpose of cooling.
