[0033] The working state of the utility model of a kind of electrical engineering experiment table convenient to maintain is as follows:

[0034] I, the overall structure of experiment table and initial state

[0035] As Figure 1 shown, the experimental bench is composed of test bench body 1, support plate 2, top plate 3, side plate 6, cover plate 8 and the like; the top end of the test bench body 1 is fixedly connected with the support plate 2, and various types of experimental required modules such as a measuring instrument module, a signal source module, an experimental circuit module and a control module are installed on the support plate 2;

[0036] The top end of the support plate 2 is fixedly connected with the top plate 3, and a sliding groove 4 is formed in the inside of the top plate 3, and the inner wall of the sliding groove 4 is symmetrically provided with a sliding block 5; one end of the sliding block 5 is rotatably connected with the side plate 6, the end of the side plate 6 away from the sliding block 5 is rotatably connected with a rotating roller 7, and one end of the rotating roller 7 is rotatably connected with the cover plate 8;

[0037] In the initial state, the sliding block 5 slides in the inside of the sliding groove 4, when the side plate 6 is located in the inside of the sliding groove 4, the cover plate 8 and the side plate 6 are designed to be parallel to each other, at this time, the clamping block 35 is clamped with the clamping groove 31 close to the inside of the sliding groove 4, and a plurality of electrical equipment can be hung on one side of the cover plate 8, for storing a plurality of electrical equipment (such as zinc oxide lightning arrester detector, phase tester and street lamp transformer, etc.), as Figure 2 shown, at this time, the cover plate 8 is located at the back of the support plate 2, so as not to affect the spacing between the test bench body 1, nor to affect the teacher walking;

[0038] II. Operation and principle during teaching

[0039] Open the cover plate 8: when teaching display is needed, due to the existence of the positioning assembly, the knob 26 needs to be first rotated; because the knob 26 is fixedly connected with the insertion rod 24, and the insertion rod 24 slides in the insertion rod groove 23, the avoiding groove 25 penetrates through the cover plate 8 and the insertion rod 24 and the knob 26 are designed in T shape, so rotating the knob 26 can make it slide in the avoiding groove 25, thereby driving the insertion rod 24 to be separated from the second insertion hole 22;

[0040] Rotate the cover plate 8 to display the equipment: after the insertion rod 24 is separated from the second insertion hole 22, rotate the two cover plates 8, through the rotating action of the rotating roller 7, so that the two cover plates 8 and the support plate 2 are similar to C type shape, as Figure 3 shown, so that all the equipment stored in the support plate 2 and the two cover plates 8 can be displayed, at this time, the personnel to be trained only need to face the test bench to see all the equipment, which is convenient for the teacher to teach and explain;

[0041] Fix the cover plate 8: in order to avoid the cover plate 8 from rotating during the display process, the rotating bolt 11 needs to be rotated; because the bolt 11 is threadedly connected with the inner wall of the groove 9 at both ends of the test bench body 1, and the top end of the bolt 11 is rotatably connected with the bottom end of the rubber pad 10, rotating the bolt 11 will make the rubber pad 10 rise until it abuts against the cover plate 8, thereby fixing the position of the cover plate 8;

[0042] III. Operation and principle during the long vacation

[0043] Mobile side plate 6: when on holiday, in order to protect the equipment in the experiment table, it is necessary to cover the experiment table; first pull the side plate 6, so that the slider 5 is subjected to tension; due to the existence of the limiting assembly, the clamping block 35 in the connecting groove 32 at the bottom of the slider 5 is clamped with the clamping groove 31, when the side plate 6 is pulled, the clamping block 35 is extruded, and the compression spring 33 is compressed, until the clamping block 35 is separated from the original clamping groove 31;

[0044] Repositioning side plate 6: when the slider 5 moves to another clamping groove 31, because of the elastic effect of the spring 33, the clamping block 35 will be re-clamped into this clamping groove 31, realizing the new position fixing of the slider 5;

[0045] Rotating side plate 6 and cover plate 8 cover the experiment table: after the clamping block 35 is clamped into the new clamping groove 31, rotate the side plate 6, so that it is at a 90 degree angle with the slider 5, then rotate the cover plate 8 through the rotating roller 7, so that it is at a 90 degree angle with the side plate 6, at this time, insert the insertion rod 24 into the first insertion hole 21 to form fixation, and combined with the top plate 3, the experiment table can be covered as shown in Figure 4 , effectively avoiding dust from entering and protecting the equipment in the experiment table.

[0046] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
