Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

The invention provides an open type top plate of a low-voltage switch cabinet, which comprises a frame 1 of the low-voltage switch cabinet and a top plate arranged on the frame 1, wherein the top plate comprises a rear top plate 2 fixedly arranged at the upper end of the frame 1 and a front top plate 3, one end of which is hinged with the frame 1 and can be opened in a turnover mode around a hinged point. When arranging main arranging in needs installation, the pin joint that the installer grasped preceding roof 3 with the hand is to the lateral margin, just can open preceding roof 3 around the pin joint upset upwards, and opening angle uses 180 as good, can directly stack back roof 2 upper ends with opening preceding roof 3, and convenient this moment is arranged main arranging from cubical switchboard top installation. The main bus bar is installed without opening a large window, so that the top plate is divided into a front top plate 3 and a rear top plate 2, and the rear top plate 2 is fixedly connected with the frame 1 without opening; only the front top plate 3 needs to be opened, so that the weight is small and the opening is easy.

Preferably, the front side and the rear side of the rear top plate 2 are respectively and fixedly connected with a middle beam 4 and a rear beam 5 of the frame 1, and the middle beam 4 and the rear beam 5 play a role in supporting and fixing the rear fixed plate.

Preferably, the rear side of the front top plate 3 is hinged with the middle beam 4, the front side of the front top plate 3 is overlapped at the upper end of the front beam 6, and when the front top plate 3 is opened, the front top plate 3 can be opened around the hinged position of the front top plate 3 and the middle beam 4 by grasping the overlapped position of the front top plate 3 and the front beam 6.

Preferably, the front top plate 3 is fixedly connected with the front beam 6 through a fixing mechanism, so that the front top plate 3 can be prevented from being opened artificially in the transportation or moving process.

Preferably, the fixing mechanism is a screw 7, and the way of fixing the screw 7 is not only simple but also firm.

Preferably, the fixing mechanism comprises a restriction plate 8 fixedly connected to the upper end of the front beam 6, a restriction rod 9 penetrates through a restriction hole in the restriction plate 8, one end of the restriction rod 9 is fixedly connected with a clamping plate 10 used for preventing the front top plate 3 from being opened, and a spring 12 is sleeved on the restriction rod 9 and used for pushing the clamping plate 10 to be clamped and fixed with the front top plate 3. Taking the front top plate 3 as an example, a specific use method of the fixing mechanism is described in detail as follows: the card plate 10 is firstly pushed to the front side, the card plate 10 moves forwards in a straight line due to the sliding fit of the constraint rod 9 and the constraint hole of the constraint plate 8, and the spring 12 is compressed during the moving process due to the spring 12 between the card plate 10 and the constraint plate 8. The cardboard 10 moves to the position that can not hinder preceding roof 3 and front beam 6 overlap joint all the time, then closes preceding roof 3 upset, and after preceding roof 3 and front beam 6 overlap joint, unclamp cardboard 10 again. The card 10 slides backward by the elastic force of the spring 12 returning by extension, and is engaged with the upper end surface of the front top plate 3. It should be noted that the two ends of the spring 12 should be fixedly connected to the constraining plate 8 and the catch plate 10, respectively, so as to avoid the spring 12 from pushing the constraining rod 9 away from the constraining plate 8 when the spring 12 is extended and reset. This is a more time-saving operation than fixing with the screw 7.

Preferably, the clamping plate 10 is a right-angle plate which can be attached to both the front end surface and the upper end surface of the front top plate 3, so that the two ends of the spring 12 do not need to be fixedly connected with the restraining plate 8 and the clamping plate 10, and the right-angle plate can prevent the clamping plate 10 from continuously sliding backwards after being abutted against the edge of the front top plate 3, thereby preventing the restraining rod 9 from being separated from the restraining plate 8.

Preferably, four corners of the upper end of the frame 1 are respectively and fixedly provided with a lifting ring 11, so that the movable switch cabinet can be conveniently lifted.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.

It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and the invention is not described in any way for the possible combinations in order to avoid unnecessary repetition.

In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
