DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-6 A test transformer control box placement rack shown in the figure includes a control box body 1 and a "U"-shaped frame body 2, an outer protective ring 21 is arranged on the frame body 2, and a supporting plate 22 with two ends fixed to the inner wall of the frame body 2 is arranged below the outer protective ring 21. When in use, the control box body 1 passes through the outer protective ring 21 and is placed on the supporting plate 22. The outer protective ring 21 provides protection for the control box body 1 on all sides to avoid direct collision with the outside; the outer protective ring 21 is provided with a clamping component for abutting and fixing the side wall of the control box body 1. When the control box body 1 is placed, the side wall of the control box body 1 is abutted and clamped by the clamping component to keep it stable between the device.

[0025] In one embodiment, through holes 3 are opened around the outer protective ring 21, and the clamping assembly includes a bolt rod 31 threadedly connected to the upper side wall of the through hole 3 and an arc-shaped protrusion 32 fixed on the bolt rod 31 and located in the through hole 3. By rotating the bolt rod 31, the arc-shaped protrusion 32 rotates to engage with the side wall of the control box body 1, so that the staff can easily and firmly clamp the control box body 1.

[0026] In one embodiment, a stabilizing mechanism for enhancing the friction between the bottom surface and the placement surface is further provided on the frame 2. Two groups of slots 33 are provided at the bottom of the frame 2. The stabilizing mechanism includes a friction plate 40 received in the slots 33 and a supporting assembly for supporting the friction plate 40 to move in the slots 33. The lower surface of the friction plate 40 is folded and provided with a rubber layer. The frame 2 lowers its center of gravity by enlarging the placement surface, so that its placement stability is higher. In order to ensure that it can be more stable during driving, a friction plate 40 is further provided. The friction plate 40 further enhances the friction between the friction plate 40 and the placement surface through the rubber layer on its surface, thereby ensuring that the placement frame will not slide in the vehicle. The friction plate 40 is not in the same plane as the bottom surface of the frame 2 in the initial state, so that it has storage properties, thereby ensuring that when the frame 2 needs to be placed in a place with a dirty surface, the surface of the friction plate 40 will not be contaminated, thereby reducing the friction effect of the rubber.

[0027] In one embodiment, the supporting assembly includes a suspension arm 4 arranged on the lower surface of the support plate 22, a movable shaft 41 rotatably arranged at both ends on the suspension arm 4, a movable rotating plate 42 arranged on the movable shaft 41, and a rotating knob 43 arranged at one end of the movable shaft 41, and arc-shaped abutting heads 44 are arranged at both ends of the movable rotating plate 42 for movably abutting against the lower surface of the support plate 22 and the upper surface of the friction plate 40 respectively, a spring 5 is arranged between the support plate 22 and the friction plate 40, and a limit baffle 6 for abutting against the movable rotating plate 42 is arranged on the frame body 2. When the friction plate 40 needs to be used to enhance the friction between the placement surface, the movable rotating plate 42 is rotated by rotating the rotating knob 43, and the arc-shaped abutting heads 44 arranged at both ends of the movable rotating plate 42 are arranged for movably abutting against the lower surface of the support plate 22 and the upper surface of the friction plate 40. 4 respectively abuts against the lower surface of the supporting plate 22 and the upper surface of the friction plate 40, and then pushes the friction plate 40 downward so that its lower surface is on the same plane as the lower surface of the frame body 2, and then cooperates with the frame body 2 to increase the contact area between the placement surface and the friction force. When the friction plate 40 is not needed to increase the friction, the rotation knob 43 can be rotated to make the arc-shaped abutment head 44 on the movable rotating plate 42 misaligned with the abutment surface, and then the friction plate 40 moves back under the action of the spring 5, so that it is retracted relative to the lower surface of the frame body 2, and then does not participate in the support. The setting of the limit baffle 6 ensures that the movable rotating plate 42 will not rotate too much when rotating to abut the friction plate 40, causing the friction plate 40 to move back again, thereby ensuring the precise control effect of the structure.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
