Figure 1 The layout direction is determined by the

[0020] The present invention will be further described below in conjunction with the embodiments and accompanying drawings: As attached Figure 1 、 2As shown in Figures 3 and 4, the convenient tool box for electric power safety detection includes a box body 1, a crossbar 2 and a rotating shaft 3. Telescopic rods are fixedly connected to the left and right parts of the crossbar 2, a limiting rod 4 is fixedly connected to the middle part of the crossbar 2, and a squeezing device is pressed and installed at the lower end of the limiting rod 4. The telescopic rod, the limiting rod 4 and the squeezing device are all installed in the shell of the box body 1. A rack 5 is fixedly connected to the outer side of the lower part of the telescopic rod, a gear 6 is fixedly installed on the left and right parts of the rotating shaft 3, and the gear 6 is meshed with the rack 5 at the corresponding position. A rotating rod 7 is fixedly connected to the left and right ends of the rotating shaft 3, and a running wheel 8 is installed on the top of the rotating rod 7. The limiting rod 4 is pressed into the shell of the box body 1 by a pressing device 9. An installation cavity may be provided in the shell of the box body 1, and the telescopic rod, the limiting rod 4 and the squeezing device are all installed in the installation cavity of the shell of the box body 1. In this way, through the coordinated use of the rotating shaft 3, the limiting rod 4, the extrusion device, the gear 6 and the rack 5, the purpose of lowering and retracting the walking wheel 8 according to actual conditions is achieved. It is safe and reliable, and the walking wheel 8 is easy to lower and retract, which facilitates operation, improves work efficiency, and greatly reduces the workload of staff during use.

[0021] The above-mentioned convenient power safety detection toolbox can be further optimized and / or improved according to actual needs: As attached Figure 1 、 2 As shown in Figures 3 and 4, the telescopic rod includes a first connecting rod 10 and a second connecting rod 11. The lower portion of the first connecting rod 10 is slidably mounted in the upper cavity of the second connecting rod 11. Two vertical first mounting grooves 12 are provided in the shell of the box body 1. The first connecting rod 10 and the second connecting rod 11 are correspondingly mounted in the first mounting grooves 12. A horizontal second mounting groove 13 is provided on the top of the shell of the box body 1. The second mounting groove 13 is connected to the first mounting groove 12. The cross bar 2 is mounted in the second mounting groove 13. The upper end of the second connecting rod 11 is fixedly connected to the cross bar 2. A rack 5 is fixedly connected to the outer side of the lower portion of the second connecting rod 11. The left and right ends of the rotating shaft 3 are respectively located outside the shell of the box body 1. The telescopic rod is well known and commonly used; this facilitates the first connecting rod 10 to be pulled out and in the second connecting rod 11.

[0022] As attached Figure 1 、 2As shown in Figure 3, the extrusion device includes a hollow cylinder 14, an elastic member 15, a moving rod 16 and a connecting plate 17. A third mounting groove 18 in the vertical direction is respectively provided in the shell of the box body 1 on the left and right sides of the limiting rod 4. The hollow cylinder 14 is fixedly installed in the third mounting groove 18, and the moving rod 16 is installed on the upper part of the hollow cylinder 14. The elastic member 15 is tightly installed on the lower part of the hollow cylinder 14. A connecting plate 17 is fixedly connected between the two moving rods 16. The lower end of the limiting rod 4 and the middle part of the connecting plate 17 are fixedly connected together. The lower end of the moving rod 16 is pressed on the elastic member 15 through the limiting rod 4. Insert rods 19 are fixedly connected to the left and right top ends of the connecting plate 17, and a limiting hole 20 corresponding to the insert rod 19 is provided on the rotating shaft 3. In this way, when the running wheel 8 is retracted, the limiting rod 4 squeezes the connecting plate 17, and the connecting plate 17 squeezes the moving rod 16, so that the elastic member 15 is in a compressed state, and the insertion rod 19 is now away from the rotating shaft 3; when the running wheel 8 is lowered, the second connecting rod 11 moves upward relative to the rotating shaft 3, and the limiting rod 4 has been lifted up to the appropriate position, and the connecting plate 17 moves up to the limiting hole 20 on the rotating shaft 3 where the insertion rod 19 is installed.

[0023] As needed, the elastic member 15 can be a spring; or / and the limiting hole 20 can be a blind hole; the upper end of the insertion rod 19 can be tapered, with a smaller top and a larger bottom; or / and the running wheel 8 can be a universal wheel. This makes the universal wheel easier to move; the upper end of the insertion rod 19 can be tapered, with a smaller top and a larger bottom, making it easier to fit the upper end of the insertion rod 19 into the limiting hole 20 on the rotating shaft 3.

[0024] As attached Figure 3 、 4 As shown, the pressing device 9 is a locking bolt. A threaded hole is provided on the housing of the box body 1 at the position corresponding to the limit rod 4. The inner end of the locking bolt passes through the threaded hole and presses against the limit rod 4. Alternatively, / or, a fourth vertical mounting slot 21 is provided on the left and right sides of the housing of the box body 1, and the rotating rod 7 is correspondingly mounted in the fourth mounting slot 21. In this way, tightening the locking bolt puts the limit rod 4 in the restricted state, and loosening the locking bolt puts the limit rod 4 in the stretchable state.

[0025] As attached Figure 4 As shown, a lid 22 is hingedly connected to the box body 1, and the box body 1 and the lid 22 are connected together by a mechanical lock 23; or / and, a lifting handle 24 is fixedly connected to the outside of the box body 1. The mechanical lock 23 and the lifting handle 24 are both well-known and commonly used. When the tools stored in the box body 1 are relatively light, they can be moved by pulling the lifting handle 24.

[0026] Advantages of the present invention: (1) The convenient tool box for electric power safety detection of the present invention can put the limit rod 4 in a stretchable state or a limited state by loosening or tightening the locking bolt, so that the rotating rod 7 and the running wheel 8 can be freely retracted and extended, which greatly reduces the burden of carrying the tool box and has the advantage of portability.

[0027] (2) The convenient tool box for electric power safety detection of the present invention can fold or lower the running wheels 8 according to actual conditions, which greatly saves space and has the characteristics of labor saving and convenience.

[0028] The working process of the present invention is as follows: When the tool stored in the box body 1 is heavy and inconvenient to lift, the locking bolt is loosened, the cross bar 2 is lifted, the limiting rod 4, the connecting plate 17 and the first connecting rod 10 move upward together, and after the first connecting rod 10 moves up to a certain position, the second connecting rod 11 is driven to move up, so that the gear 6 rotates relatively on the rack 5 on the second connecting rod 11, driving the rotating shaft 3 to rotate, and the rotation of the rotating shaft 3 drives the rotating rod 7 and the traveling wheel 8 on it to rotate downward until the rotating shaft 3 rotates to a preset angle. At this time, the upper end of the inserting rod 19 is close to the rotating shaft 3 and the inserting rod 19 is inserted into the limiting hole 20 on the rotating shaft 3, thereby limiting the rotating shaft 3. At the same time, the rotating shaft 3 limits the first connecting rod 10 through the cooperation of the gear 6 and the rack 5, tightens the locking bolt to limit the limiting rod 4, and then limits the cross bar 2 and the first connecting rod 10. The first connecting rod 10 cooperates with the rotating rod 7 and the traveling wheel 8, and then the tool box can be pulled, which greatly reduces the carrying burden and has the advantage of portability.

[0029] When the box body 1 needs to be stored, the locking bolt is loosened and the cross bar 2 is pressed down. The cross bar 2 drives the first connecting rod 10 and the limit rod 4 to move downward, the limit rod 4 squeezes the connecting plate 17, the connecting plate 17 squeezes the moving rod 16, and the upper end of the insertion rod 19 disengages from the limit hole 20 on the rotating shaft 3. The cross bar 2 is continued to be pressed down. The first connecting rod 10 drives the second connecting rod 11 to move downward, driving the rotating shaft 3 and the rotating rod 7 to rotate, and the rotating rod 7 drives the walking wheel 8 to rotate upward until it is reset (the rotating rod 7 and the walking wheel 8 are correspondingly installed in the fourth mounting groove 21, and the cross bar 2 is installed in the second mounting groove 13). At this time, the elastic member 15 is in a compressed state, the insertion rod 19 is away from the rotating shaft 3, and the locking bolt is tightened to limit the limit rod 4 again, so that the rotating rod 7 and the walking wheel 8 are in the storage state.

[0030] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
