Description

Line following device suitable for large-depth-dimension chassis Technical Field The utility model belongs to the field of cabinet cable wiring in power equipment, and particularly relates to a line following device suitable for a large-depth-dimension chassis. Background Currently, in electrical equipment cabinets, there are a variety of single cabinets (19 inches wide) that employ a back-out approach that are pulled out of and inserted into the cabinet by means of rails on both sides. When the single machine case is pulled out and inserted into the cabinet, damage to the tail cable is avoided, and a line following device for supporting the cable needs to be designed at the rear part of the single machine case. The cable tracking devices currently generally employ a toggle type structure with a housing width of 19 inches, so the housing depth cannot exceed 450mm. If the depth of the single machine case exceeds 800mm, the common line following device cannot meet the line following requirement of the tail cable, for example, if a plurality of line following sections are added, the rotation nodes between the line following sections are also added, and when the machine case is pulled out and pushed back into the machine cabinet, the line following device cannot realize following rotation due to the straightened state, and the line following device cannot be switched to a reverse folding state. In the prior art, as in patent application CN202311540530.0, a general cable line-following frame device for a cabinet is proposed, and the technical scheme adopted is that a line-following frame device with fixed length in the prior art is split and sleeved and assembled, so that the length of a front (rear) line-following frame assembly is adjustable, and the device can adapt to the use requirements of extension units with different depths, while in patent application CN202310343291.3, a cable line-following frame mechanism which aims at small-sized products and can meet the movement and disassembly functions of the products is disclosed, and the technical scheme adopted is that a supporting beam is arranged at the rear part of the extension unit and is fixed on the movable parts of guide rails positioned at two sides of the extension unit, and the movable end of the line-following frame mechanism is connected with the supporting beam through a quick lock, and the fixed end of the line-following frame mechanism is fixed in the cabinet. It can be seen that, in the above technical solution, even if the line following frame device adapted to different depths is provided, the line following frame device adopts a mode of increasing the length of the line groove board assembly, and when the whole width of the facing chassis is shorter than the depth of the cabinet, the prior art still cannot effectively solve similar problems when the line following units of multiple stages are required to be arranged. Therefore, there is a need for a line following device that is suitable for a chassis with a large depth and can be applied to various situations. Disclosure of utility model In view of one or more of the above-mentioned drawbacks or improvements of the prior art, the present utility model provides a line following device suitable for a chassis with a large depth, wherein the problem that a plurality of line following units cannot effectively follow the motion of the chassis is overcome by configuring an elastic mechanism, so that the line following device can be configured with a plurality of line following units for being applied to the chassis with a large depth. In order to achieve the above-mentioned objective, the present utility model provides a line following device suitable for a chassis with a large depth dimension, which is disposed between the chassis and a cabinet, and comprises a line following assembly, wherein the line following assembly comprises at least two line following units which are sequentially arranged, and two adjacent line following units are rotationally connected, so that the line following assembly can be folded, stored or unfolded and elongated; The line following unit at the first end of the line following assembly is rotationally connected with the chassis, and the line following unit at the second end of the line following assembly is rotationally connected with the cabinet; The line following assembly further comprises at least one elastic mechanism, two ends of the elastic mechanism are connecting ends, and the two connecting ends are respectively connected with the two line following units and used for providing pretightening force for the two line following units. As a further improvement of the present utility model, the elastic mechanism includes a first sliding unit, a second sliding unit, and an elastic member; The first sliding unit is in sliding connection with the second sliding unit, one end, away from the other sliding unit, of the sliding unit is a connecting end, and the connec
