Further, the pulling module 401 further comprises elastic adapters 401 d. In addition, the driving member 401b has a first fixing buckle 401b-2, and the driven member 401c has a second fixing buckle 401 c-3. The driving member 401b is divided into a first section D-1 and a second section D-2 by a second hinge point J-2, wherein the section between the first hinge point J-1 and the second hinge point J-2 is the first section D-1, and 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 holder buckle 401b-2 is disposed on the second section D-2 such that the distance between the first holder buckle 401b-2 and the first hinge point J-1 is greater than the distance between the second hinge point J-2 and the first hinge point J-1. The second holder buckle 401c-3 is fixed in a non-end position on the follower 401 c. The elastic adaptor 401D is fixed to the first fixing buckle 401b-2 at one end and the second fixing buckle 401c-3 at the other end, and the elastic adaptor 401D in the present invention can be an extension spring, in order to ensure that the elastic adaptor 401D can perform corresponding displacement in a self-adaptive and unimpeded manner during the process of driving the pulling module 401 to move integrally by the driving member 401b, the first section D-1 and a part of the second section D-2 of the driving member 401b are hollow in the middle to allow the elastic adaptor 401D to perform corresponding movement in a "hollow structure". The first fixing buckle 401b-2 is a short column structure fixed between two hollow interlayers of the driving part 401 b; the second fixing buckle 401c-3 is a short column structure fixed between the upper and lower parallel frames of the driven member 401 c.
The locking process of the connection assembly 400 is as follows:
the connecting end 401c-1 of the driven piece 401c is hooked on the matching module 402 of the adjacent side looped network cabinet monomer (only contact and no extrusion effect is realized at the moment), and then the operating end 401b-1 is pushed clockwise until the deformation layer 401c-2 begins to be pressed and deformed, and the horizontal included angle between the driving piece 401b and the driven piece 401c is smaller than 180 degrees. If the operating end 401b-1 is pushed clockwise, the required pushing force is gradually increased, the pulling tension applied to the driven member 401c is correspondingly increased, and the deformation space of the deformation layer 401c-2 and the driven member 401c enables the operating end 401b-1 to be pushed continuously. In this process, the elastic adapter 401d is also gradually elongated.
When the operating end 401b-1 is further pushed clockwise until the first hinge point J-1, the second hinge point J-2 and the deformation layer 401c-2 are collinear, the pulling force applied to the follower 401c reaches a maximum (the deformation degree of the deformation layer 401c-2 also reaches a maximum), and at this time, the elastic adapter 401d is also pulled to the maximum. If the operating end 401b-1 is pushed clockwise continuously, in the subsequent process, the driven member 401c gradually returns to the normal state, the pulling force is released, the deformation degree of the deformation layer 401c-2 is reduced accordingly, the required driving force is reduced rapidly, and even the operating end 401b-1 automatically rotates clockwise under the condition that the driven member 401c and the deformation layer 401c-2 return to the normal state until the operating end 401b-1 touches the surface of the shell 200, so that the operating end 401b-1 cannot rotate continuously. At this time, the coupling assembly 400 is integrally formed in a locked state, and the driving member 401b cannot rotate counterclockwise by itself (because it will be subjected to a greater tension) unless it is driven counterclockwise by 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 adapter 401d can pull the driving member 401b and the driven member 401c, and has a function of preventing the loosening rotation.
Further, the connecting assembly 400 further includes a safety module 403, wherein the safety module 403 has a hook shape and an outer surface of the safety module is a convex curved surface.
The handle end 401b-1 may be cylindrical with a hollow first chamber 401b-11 and a second chamber 401b-12 therein. 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 at the interface between the two.
The first chamber 401b-11 is inserted with a telescopic member 401b-13, the telescopic member 401b-13 is a cylindrical structure, an inner end of the telescopic member is inserted into the inner second chamber 401b-12, an outer end of the telescopic member passes through the first chamber 401b-11, and an operation end 401b-1 is exposed (the outer end of the first chamber 401b-11 is provided with a corresponding socket communicated with the outside). In addition, the telescopic part 401b-13 is provided with a limiting ring 401b-14 positioned in the range of the first cavity 401b-11, and the limiting ring 401b-14 is in a ring shape, is larger than the maximum size of a socket of the outer end head of the first cavity 401b-11 and is slightly smaller than the inner diameter of the first cavity 401b-11, so that the telescopic part 401b-13 cannot be separated from the first cavity 401 b-11. The first chamber 401b-11 also has a spring 401b-15 therein, the spring 401b-15 being a compression spring that fits over the telescoping member 401b-13, with one end resting against the stop collar 401b-14 and the other end resting against the inner end face of the first chamber 401b-11 (i.e., the step face formed by the first chamber 401b-11 and the second chamber 401 b-12).
Thus, when the operating end 401b-1 is pushed clockwise, the exposed portion of the outer end of the telescoping member 401b-13 can reach the safety module 403. Because the outer surface of the safety module 403 is convexly curved, it can slide along the convexly curved surface while the telescoping members 401b-13 retract into the first and second chambers 401b-11 and 401 b-12.
Preferably, the outer end of the telescopic member 401b-13 is also configured as a convex curved surface, and when the operation end 401b-1 is pushed clockwise, the convex curved surface of the telescopic member 401b-13 can contact with the convex curved surface of the safety module 403 to form extrusion, which is more favorable for sliding between the two. After the outer ends of the telescopic members 401b-13 slide into the hook body along the convex curved surface of the safety module 403, the telescopic members 401b-13 are exposed again after rebounding, and the safety module 403 can block the telescopic members, so that the possibility of loosening and rebounding is further prevented.
Further, the operating end 401b-1 is bent with respect to the first section D-1 in a counterclockwise direction, so that the operating end 401b-1 has a larger clockwise rotation space, and a larger obtuse angle is obtained between the first section D-1 and the driven member 401c, thereby reducing the structural instability of the driven member 401c due to the possibility of tension.
