[0046] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0048] Example 1

[0049] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, a test board fixing protection device comprises a bottom box 1, inside of which a test board 11 is fastened and installed by bolts; a cover unit 2 is arranged above the bottom box 1 and four corners of the cover unit 2 are threadedly penetrated with fastening bolts 21, wherein the cover unit 2 is assembled above the bottom box 1 by the fastening bolts 21 to form a protection structure;

[0050] The cover unit 2 includes a main board 22 and a sub-board 23 located on both sides of the main board 22. Both sides of the main board 22 are convexly formed with a lap platform 24, and the sub-board 23 is formed with a lap groove 25 corresponding to the lap platform 24. The main board 22 is lapped on the sub-board 23 through the lap platform 24 to form protection for the test board 11. The lap groove 25 can support the lap platform 24, thereby achieving support of the main board 22 on the sub-board 23;

[0051] As a further advantage of this embodiment, please refer to Figure 2 and Figure 3 An upper magnetic block 26 is embedded below the lap platform 24, a lower magnetic block 27 attracted to the upper magnetic block 26 is embedded in the lap groove 25, and a fastening bolt 21 is provided on the sub-plate 23;

[0052] The test board fixing protection device provided in this embodiment can fix the main board 22 on the sub-board 23 when the upper magnetic block 26 and the lower magnetic block 27 attract each other, thereby ensuring that the main board 22 can form a stable engagement state on the sub-board 23 during actual use and is not easy to fall off, thereby ensuring that the protective space jointly formed between the cover unit 2 and the bottom box 1 is used to protect the test board 11, effectively avoiding direct contact between the test board 11 and the outside when the electrical equipment is tested;

[0053] In this embodiment, a plurality of through holes (not shown in the figure) can be opened on the surface of the main board 22 for connecting the test board 11 with the external test circuit, and the partially opened through holes for circuit connection will not affect the protective effect of the bottom box 1 and the cover unit 2 on the test board 11 as a whole.

[0054] Example 2

[0055] The test board fixing and protecting device provided in Example 1 is further optimized. Specifically, Figure 4 and Figure 5 As shown, fastening units 3 are provided on both sides of the end of the cover unit 2;

[0056] The fastening unit 3 includes a movable groove 31 formed at the corner of the main plate 22 and a positioning block 32 rotatably arranged in the movable groove 31 through a pin shaft, wherein the sub-plate 23 is provided with an insertion groove 33 at a position corresponding to the positioning block 32, and the positioning block 32 can rotate in the movable groove 31 and turn into the insertion groove 33 to form a limiting effect;

[0057] Through the above structural design, the positioning block 32 is turned over in the insertion groove 33 to form a Figure 5In the state shown, the positioning block 32 releases the limiting effect on the auxiliary board 23, and the main board 22 can be disassembled by pushing the main board 22 upward, while the auxiliary board 23 is still stably assembled on the top of the bottom box 1 by the fastening bolts 21. At this time, the test board 11 can be exposed, which is convenient for the operator to detect, sort and replace the test board 11;

[0058] Compared with the integrated structural design of the cover plate unit 2, there is no need to repeatedly disassemble the fastening bolts 21, and there is no need to use tools for disassembling the fastening bolts 21, which is convenient for operators. At the same time, if the fastening bolts 21 are frequently used to disassemble and assemble the cover plate unit 2, the fastening bolts 21 are likely to form a "slipped thread" state at the connection position with the bottom box 1, resulting in the fastening bolts 21 being unable to be tightened.

[0059] As a further optimization in this embodiment: a rubber convex button 34 is provided below the positioning block 32;

[0060] The rubber knob 34 itself has a certain elasticity and will deform itself after being subjected to external pressure. Its application in this embodiment can promote the stability of the positioning block 32 being screwed into the insertion groove 33.

[0061] Specifically, when the positioning block 32 is flipped into the insertion groove 33, the rubber convex ball 34 will also be squeezed into the movable groove 31 simultaneously. When the rubber convex ball 34 is located in the movable groove 31, it will form a resistance against the inner wall of the movable groove 31 through its own elastic force, thereby forming a resistance to the positioning block 32, thereby ensuring the stable clamping between the main board 22 and the sub-board 23.

[0062] Example 3

[0063] The test board fixing and protecting device provided in Example 2 is further optimized, such as Figure 4 , Figure 5 and Figure 6 As shown, a toggle rod 35 is connected to the top of the positioning block 32 , and an arc groove 36 is formed on the sub-plate 23 , and the arc groove 36 coincides with the rotation trajectory of the toggle rod 35 .

[0064] Compared with the operation of directly driving the positioning block 32 in the second embodiment, the contact area between the operator's hand and the positioning block 32 is increased by setting the toggle rod 35, thereby facilitating the toggle of the positioning block 32, so that the positioning block 32 can be better placed in the arc groove 36 to form a locked state;

[0065] Specifically, if it is necessary to disassemble the cover unit 2 and inspect, clean or replace the test board 11, push the toggle rod 35 in the arc groove 36 to rotate it outward. During the rotation, the positioning block 32 will rotate outward inside the insertion groove 33. When the positioning block 32 is rotated into the insertion groove 33, the main board 22 is pushed upward, so that the upper magnetic block 26 and the lower magnetic block 27 are separated from each other, and the main board 22 can be disassembled to meet the operation requirements of the test board 11.

[0066] Example 4

[0067] The test board fixing and protecting device provided in Example 3 is further optimized, such as Figure 4 , Figure 5 and Figure 6 As shown, a fastening cap 38 is threadedly mounted on the toggle rod 35, and the fastening cap 38 can be rotated to slide with the toggle rod 35 and abut against the sub-plate 23;

[0068] The toggle rod 35 is also sleeved with an anti-skid washer 39, which is located below the fastening cap 38 and connected thereto;

[0069] The difference from the third embodiment is that a fastening cap 38 is added to the surface of the toggle rod 35 in the present embodiment, so that when the main board 22 is engaged and fixed on the sub-board 23, the bottom of the fastening cap 38 can be rotated to abut against the surface of the sub-board 23, and the movement of the toggle rod 35 is hindered by the friction between the fastening cap 38 and the sub-board 23, thereby further ensuring the stable engagement of the positioning block 32 on the toggle rod 35 in the insertion groove 33, and ensuring the stability of the protective space formed between the cover unit 2 and the bottom box 1.

[0070] At the same time, in this embodiment, the anti-skid washer 39 is provided so that when the fastening cap 38 slides on the surface of the toggle rod 35 to form a resistance to the sub-plate 23, the anti-skid washer 39 can be interposed between the fastening cap 38 and the sub-plate 23, which not only effectively transmits the resistance force of the fastening cap 38 and ensures the stable limit of the positioning block 32, but also avoids direct contact between the fastening cap 38 and the sub-plate 23, effectively protects the sub-plate 23, and avoids the situation that the fastening cap 38 is easy to form scratches with the sub-plate 23;

[0071] As a further optimization of this embodiment: the top of the toggle rod 35 protrudes from the surface of the main board 22 and is parallel to the top of the fastening bolt 21. By arranging the toggle rod 35 and the fastening bolt 21 at the same height, when the device is subjected to external pressure, the toggle rod 35 can form a supporting structure together with the fastening bolt 21 to effectively transfer and disperse the pressure, thereby avoiding the situation where the toggle rod 35 is too low and only the fastening bolt 21 bears the pressure, or the toggle rod 35 is too high and only the toggle rod 35 bears the pressure, which is beneficial to the overall protective use of the protective device.

[0072] The use process of the test board fixing protection device provided by the utility model is as follows: the test board 11 is fixedly installed inside the bottom box 1 by bolts, and then the sub-board 23 is fixed to the two sides of the top of the bottom box 1 by fastening bolts 21, and then the main board 22 is engaged with the surface of the sub-board 23 by the mutual attraction between the upper magnetic block 26 and the lower magnetic block 27, and then the toggle rod 35 is rotated to flip the positioning toggle block 32 on it into the insertion groove 33, and then the fastening cap 38 is rotated to make the anti-skid gasket 39 on it contact the surface of the sub-board 23, thereby achieving the relative engagement and fixation between the main board 22 and the sub-board 23.

[0073] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
