[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] The present invention will be further described below in conjunction with the embodiments. Example

[0017] An electrical cabinet anti-collision device according to this embodiment, such as Figure 1-5 As shown, it includes a bottom plate 1, the surface of the bottom plate 1 is annularly equidistantly hinged with a set 3, the inside of the set 3 is fixedly connected with a first connecting spring 4, one end of the set 3 is inserted with a plug-in 5, and the end of the plug-in 5 placed inside the set 3 is fixedly connected to the first connecting spring 4, a base 6 is arranged above the bottom plate 1, and the ends of the plug-in 5 that are far away from each other are hinged to the inner wall of the base 6, and a cabinet 7 is installed on the top surface of the base 6, and the inside of the cabinet 7 is equidistantly and symmetrically hinged with an insertion rod 11, one end of the insertion rod 11 is fixedly connected with a second connecting spring 12, and a sleeve rod 13 is sleeved on the surface of the insertion rod 11, one end of the second connecting spring 12 is fixedly connected to the inner wall of the sleeve rod 13, and the end of the sleeve rod 13 that is close to each other is hinged with a mounting plate 14; An expansion sleeve 8 is fixedly connected to the surface of the cabinet 7, and the expansion sleeve 8 is connected to the interior of the cabinet 7. The surface of the expansion sleeve 8 is annular and equidistantly provided with grooves. The inner surface of the expansion sleeve 8 is annular and equidistantly fixed with expansion blocks 9. The surface of the expansion sleeve 8 is provided with a screw sleeve 10 through a threaded sleeve. A limiting wedge 15 is inserted through the surface of the mounting plate 14, a groove is provided inside the cabinet 7, the limiting wedge 15 passes through the mounting plate 14 and extends into the groove provided inside the cabinet 7, a guide block 17 is fixedly connected to the inner bottom surface of the cabinet 7, a slide groove is provided on the bottom surface of the limiting wedge 15, and the slide groove provided on the bottom surface of the limiting wedge 15 is adapted to the guide block 17; The surface of the mounting plate 14 is provided with sawtooth cable harness grooves 16 symmetrically and equidistantly.

[0018] In this embodiment, the base plate 1 is used as a component installed on the ground. The user can install components by opening holes on the surface of the mounting plate 14 through the transverse grooves opened on the surface of the mounting plate 14, and then buckle the external wires of the components in the serrated wire groove 16, and extend one end of the external wire through the expansion sleeve 8 and the screw sleeve 10 to the outside of the base plate 1. At the same time, the user needs to leave a part of the external wire to adapt to the movement amplitude of the mounting plate 14 when it is hit. When all the components to be installed are installed, all the external wires pass through the expansion sleeve 8 and the screw sleeve 10. The expansion sleeve 8 conflicts with the expansion sleeve 8 due to the passage of multiple groups of external wires, so that the outer diameter of the expansion sleeve 8 increases to a certain extent. At this time, the user can rotate the screw sleeve 10, and the screw sleeve 10 gradually rotates to the surface of the expansion sleeve 8 through the action of the thread, so that the expansion sleeve 8 produces a certain degree of tightening effect through the movement of the screw sleeve 10, and each group of expansion blocks 9 inside the expansion sleeve 8 conflicts with the surface of the external wire, bringing a certain degree of clamping and locking effect to the external wire. Then the cabinet door 7 is closed. When the cabinet 7 is impacted by an external force, the cabinet 7 is subjected to the impact force and transmits the impact force to the base 6. Thus, the base 6 receives the impact force transmitted, causing each group of plug-ins 5 to extend or extend into the inside of the kit 3. As a result, the first connecting spring 4 connected to the kit 3 and the plug-in 5 is compressed or stretched to undergo elastic deformation. In this process, the kit 3 and the plug-in 5 rotate along their respective hinge axes to adapt to the extension and extension of the kit 3 and the plug-in 5, thereby providing a buffering and protective effect for the cabinet 7 installed on the top surface of the base 6. In addition, when the cabinet 7 is subjected to external impact, part of the force is transmitted to each group of plug rods 11 inside the cabinet 7. The plug rods 11 are subjected to the impact force, so that the sleeve rod 13 slides on the surface of the plug rod 11, squeezing the second connecting spring 12 to compress or stretch. The hinge shafts at the ends of the plug rods 11 and the sleeve rod 13 are adapted to the movement of the plug rods 11 and the sleeve rod 13 and rotate at a certain angle to use the movement of the plug rods 11 and the sleeve rod 13. When the cabinet 7 is impacted, the mounting plate 14 connected to the sleeve rod 13 synchronously swings to a certain extent, thereby further consuming the work generated when the cabinet 7 is impacted, and further providing a buffering and protective effect for the components installed on the surface of the mounting plate 14 inside the cabinet 7. Furthermore, when the user opens the door of the cabinet 7 to inspect the components installed on the surface of the mounting plate 14 inside the bottom plate 1, the user can push and remove the limiting wedge 15 originally inserted on the surface of the guide block 17, and then insert the limiting wedge 15 into the through hole on the surface of the limiting wedge 15 for the limiting wedge 15 to pass through, until it extends to the groove opened inside the cabinet 7. At this time, the mounting plate 14 can be locked by the limiting wedge 15, so that the user can perform maintenance and repair operations on the components on the surface of the mounting plate 14.

[0019] like Figure 2As shown, the top surface of the bottom plate 1 is provided with spherical grooves at equal intervals in an annular shape, and balls 2 are arranged in the spherical grooves provided on the top surface of the bottom plate 1 , and the surface of the balls 2 abuts against the inner top surface of the base 6 .

[0020] The arrangement of the ball bearings 2 can prevent the base 6 from sliding above the bottom plate 1 when the cabinet 7 is impacted. The inner bottom surface of the base 6 does not need to be in direct contact and friction with the top surface of the bottom plate 1. The ball bearings 2 are spaced apart and the ball bearings 2 roll in the spherical grooves provided on the top surface of the bottom plate 1 through the friction force generated by the movement of the base 6 in contact with the inner top surface of the base 6, which brings an auxiliary conduction effect to the base 6. While avoiding friction and wear, the movement of the base 6 when the top surface of the bottom plate 1 is impacted is made smoother.

[0021] Among them, the hinge axis hinged between the insertion rod 11 and the cabinet body 7, the hinge axis hinged between the sleeve rod 13 and the mounting plate 14, the hinge axis hinged between the kit 3 and the base plate 1, and the hinge axis hinged between the plug-in 5 and the base 6 are all sleeved with torsion springs, and the two ends of the torsion spring are fixedly connected to the two groups of components connected to their hinge axes.

[0022] By arranging the torsion springs on each hinge shaft, the second connecting spring 12 and the first connecting spring 4 can further share a part of the impact force, thereby bringing better anti-collision and anti-impact effects to the device as a whole.

[0023] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
