[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This utility model provides, for example Figure 1-3 The relay protection debugging toolbox shown.

[0035] Example 1: Includes a carrier box 1, a drawer 2, and a locking assembly 3. The bottom of the carrier box 1 is equipped with casters. The outer wall of the drawer 2 is slidably connected to the carrier box 1. The drawer 2 is used to hold and store tools for relay protection debugging, such as relay protection testers, insulation resistance testers, multi-functional power quality analyzers, power supplies, connecting wires, adapters, and hand tools. The depth of the drawer 2 corresponds to the depth of the tools it holds. Thus, with the help of the casters, the carrier box 1 can easily carry and move the relay protection tester, insulation resistance tester, multi-functional power quality analyzer, power supply, connecting wires, adapters, and hand tools. The locking assembly 3 is located in the drawer 2. On the front, the locking assembly 3 includes a fixing block 31, a mounting plate 32, a locking lever 33, and an unlocking assembly 34. One side of the fixing block 31 is fixedly connected to the carrier box 1, and there is a certain gap between the fixing block 31 and the side of the drawer 2, so as not to affect the drawing out or closing of the drawer 2. The mounting plate 32 is fixedly connected to the front of the drawer 2. The outer wall of the locking lever 33 is slidably connected to the mounting plate 32, and one end of the outer wall of the locking lever 33 is slidably engaged with the fixing block 31, so as to ensure the stability of the drawer 2 when closed. The unlocking assembly 34 is disposed between adjacent mounting plates 32. The unlocking assembly 34 is used to drive the locking lever 33 to separate from the fixing block 31, thereby unlocking the drawer 2.

[0036] Furthermore, one end of the mounting plate 32 has a through hole, the outer wall of the locking rod 33 is slidably sleeved with the inner cavity of the through hole, and the fixing block 31 has a locking groove on the side facing the mounting plate 32. One end of the outer wall of the locking rod 33 is slidably engaged with the inner cavity of the locking groove, thereby locking the drawer 2. When the locking rod 33 is separated from the locking groove on the fixing block 31, the drawer 2 can be unlocked. The locking assembly 3 also includes a slide groove 39 and a slider 310. The slide groove 39 is opened on the inner wall of the through hole, and the slider 310 is fixedly connected to the outside of the locking rod 33. The outer wall of the slider 310 is slidably engaged with the inner cavity of the slide groove 39. Under the action of the slider 310, the locking rod 33 can only slide relative to the mounting plate 32 and cannot rotate relative to the mounting plate 32.

[0037] Furthermore, the locking assembly 3 also includes a mounting groove 35, a fixing collar 36, a limiting spring 37, and a limiting collar 38. The mounting groove 35 is located at the other end of the mounting plate 32. The fixing collar 36 is fixedly sleeved on the outside of the locking rod 33 and slidably sleeved on the inside of the mounting groove 35. The limiting spring 37 is slidably sleeved on the outside of the locking rod 33 and is located on the side of the fixing collar 36 away from the fixing block 31. The limiting spring 37 can provide an elastic compressive force to the locking rod 33 through the fixing collar 36, thereby keeping the locking rod 33 stably engaged with the locking groove on the fixing block 31. The limiting collar 38 is fixedly sleeved on the inside of the mounting groove 35 and is located on the side of the fixing collar 36 facing the fixing block 31. The limiting collar 38 can limit the locking rod 33 through the fixing collar 36, preventing the locking rod 33 from popping out directly under the action of the limiting spring 37 when the drawer 2 is pulled out.

[0038] Example 2: Based on Example 1, the unlocking component 34 includes a drive sleeve 341, a spiral groove 343, and a drive shaft 342. The drive sleeve 341 is disposed between adjacent mounting plates 32 and is sleeved on the outside of the locking rod 33. Under the constraint of the limiting collar 38, the locking rod 33 will not directly separate from the drive sleeve 341. Furthermore, the stability of the drive sleeve 341 installation is ensured by the constraint of the two mounting plates 32. The spiral groove 343 is formed inside the drive sleeve 341, and the spiral grooves 343 at both ends of the inner cavity of the drive sleeve 341 are formed in opposite directions. One end of the drive shaft 342 is fixedly connected to the locking rod 33, and the outer wall of the drive shaft 342 is slidably sleeved with the inner cavity of the spiral groove 343. Figure 2 and Figure 3 As shown, when the drive sleeve 341 is rotated, the opposing spiral grooves 343 inside the drive sleeve 341 can drive the two locking rods 33 to move relative to each other or in opposite directions through the two drive shafts 342, thereby unlocking the locking rods 33.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
