Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Example 1: as shown in fig. 1-2, a tablet is marked to relay protection definite value district's function for relay protection device is last, it includes bottom plate 3, panel 4 and curb plate 1, through 1 fixed connection of curb plate all around between bottom plate 3 and the panel 4, be equipped with the square hole 2 of a plurality of ranges on panel 4, be equipped with knob device 5 at the side of square hole 2, be equipped with longitudinal baffle 9 on panel 4 the right, longitudinal baffle 9's right side limit is equipped with a plurality of cross slabs 8, longitudinal baffle 9 and cross slab 8's bottom and bottom plate 3 fixed connection form a plurality of square cavities 6, be equipped with the jack on the side of square cavity 6, there is card 7 in the square cavity 6, there is definite value function explanation characters on the card 7.

Further, the knob device 5 comprises a disc 54, a connecting rod 53 and a button 51, the disc 54 is located in the cavity between the bottom plate 3 and the panel 4, the button 51 is located above the panel 4, the connecting rod 53 penetrates through a hole on the panel 4, two ends of the connecting rod 53 are respectively fixedly connected with the disc 54 and the button 51, a compression spring 52 is sleeved on the connecting rod 53, the compression spring 52 is located between the button 51 and the panel 4, and the connecting rod 53 can rotate.

Further, the disc 54 is marked with a descriptive text, and the square hole 2 is positioned at the upper side of the disc 54.

Further, the leftmost column of the panel 4 is an area code, and area code explanatory characters are respectively pasted on the panel 4: 00-06. The second column describes the mode, the characters on the disk 54 in the second column are "normal" and "temporary", respectively, and the disk 54 is rotated to place the characters of "normal" or "temporary" in the square hole 2, respectively, to indicate the selection of the mode of constant value. The third column to the eighth column are combined together to form a fixed value single number, the characters on the disks 54 in the third column to the eighth column are numbers 0-9 respectively, different disks 54 are rotated respectively, and the needed numbers on the disks 54 are placed in the square holes 2, so that different fixed value single numbers can be obtained.
