In the present invention, the connecting assembly 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 assemblies 400 . The connection assembly 400 includes a pulling module 401 and a matching module 402, wherein the pulling module 401 is a linkage structure for connecting the single side of the ring network cabinet, and the matching module 402 is used for pulling the single side of the single side 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 combined and connected in sequence after being arranged arbitrarily, in order to ensure orderliness, each ring main unit includes a plurality of connection components 400, wherein 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.

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 assembly 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 assembly 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 assembly 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.

It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be Modifications or equivalent substitutions without departing from the spirit and scope of the technical solutions of the present invention should be included in the scope of the claims of the present invention.
