[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-5This utility model provides a temporary power distribution box, including a distribution box body 1; a handle 11 is fixedly connected to one side wall of the distribution box body 1; a storage box 12 is fixedly connected inside the distribution box body 1; multiple sets of expansion posts 13 are arranged inside the storage box 12; the bottom of the expansion posts 13 is located below the distribution box body 1; connecting seats 14 are slidably connected to both side walls of the expansion posts 13; a first rotating wheel 15 is rotatably connected between a pair of connecting seats 14; a threaded rod 16 is fixedly connected to the top of the first rotating wheel 15; an expansion groove 17 is opened inside the expansion post 13; a threaded rotating post 18 is rotatably connected to the bottom of the expansion post 13; the threaded rotating post 18 is threadedly connected to the threaded rod 16; a return spring 19 is fixedly connected to the top of the inner side of the expansion groove 17; the bottom of the return spring 19... The first wheel 15 is connected to the top of the threaded rotating column 18. During operation, the operator can use the handle 11 to move the first rotating wheel 15, which in turn moves the distribution box body 1. When the first rotating wheel 15 is pressed, it pushes the threaded rod 16 upward. Since the threaded rod 16 and the threaded rotating column 18 are threadedly connected, the return spring 19 deforms. When the distribution box body 1 passes through a concave surface, the first rotating wheel 15 is no longer under force. The deformed return spring 19 can drive the first rotating wheel 15 downward through the threaded rotating column 18, so that the first rotating wheel 15 contacts the ground. The overall device improves the stability of the distribution box body 1 during movement and enhances its adaptability when passing through concave and convex surfaces. It also reduces the possibility of damage to internal parts caused by large vibrations of the distribution box body 1.

[0027] Furthermore, such as Figure 3 As shown, a pair of first fixed seats 2 are fixedly connected to one side wall of the distribution box body 1; each of the first fixed seats 2 has a rotating shaft 21 rotatably connected to its side wall; a first spring post 22 is fixedly connected to the bottom end of the rotating shaft 21; a limit sleeve post 23 is fixedly connected to the end of the rotating shaft 21 near the first fixed seat 2; a limit ring 26 is fixedly connected to the top of the first fixed seat 2; a connecting rod 25 is slidably connected to the inner side of the limit ring 26; a locking post 24 is fixedly connected to the bottom end of the connecting rod 25; during operation, the operator rotates the rotating shaft 21... This ensures that the bottom end of the first spring column 22 maintains a suitable contact angle with the ground, and the connecting rod 25 can be moved by the limit ring 26, so that the locking column 24 and the limit sleeve column 23 mesh with each other, thereby achieving the fixed work of the adjusted rotating shaft 21. When the distribution box body 1 is tilted, the pair of first spring columns 22 can contact the ground and be stored inward of the rotating shaft 21, which improves the buffering effect on the distribution box body 1, thereby reducing the occurrence of parts damage after the distribution box body 1 is tilted.

[0028] Furthermore, such as Figure 3As shown, the first spring column 22 has a toothed groove 3 on its side wall; multiple sets of toothed grooves 3 are provided on the side wall of the first spring column 22; a first gear 31 is rotatably connected to the bottom of the rotating shaft 21; the toothed groove 3 and the first gear 31 mesh with each other; a second gear 32 is rotatably connected to the bottom of the rotating shaft 21; the second gear 32 and the end of the first gear 31 away from the toothed groove 3 mesh with each other; a second wheel 33 is slidably connected to the side wall of the rotating shaft 21; the second wheel 33 and the second gear 32 mesh with each other; during operation, when the first spring column 22 is in contact with the ground and the first spring column 22 is retracted into the inner side of the rotating shaft 21, the toothed groove 3 drives the first gear 31 to rotate. The rotating first gear 31 can drive the second wheel 33 to move downward through the second gear 32, so that the outer wall of the second wheel 33 contacts the ground, thereby achieving the effect of supporting the inclined distribution box body 1, and the second wheel 33 can rotate with it; the overall device improves the stability of the distribution box body 1 when it moves.

[0029] Furthermore, such as Figure 3 As shown, a pair of first fixed seats 2 are fixedly connected to a second fixed seat 4 at one end away from each other; a second spring post 41 is fixedly connected to the side wall of the second fixed seat 4; the second spring post 41 is connected to the connecting rod 25; during operation, the second spring post 41 can drive the connecting rod 25 to move towards the rotating shaft 21 through the limiting ring 26 via the second fixed seat 4, so that the locking post 24 and the limiting sleeve post 23 are always engaged when not operated by the operator, thereby improving the stability when fixing the rotating shaft 21.

[0030] Furthermore, such as Figure 3 As shown, a protective soft plate 5 is fixed to the bottom end of the first spring column 22. During operation, before the bottom of the first spring column 22 contacts the ground, the protective soft plate 5 contacts the ground first. Since the protective soft plate 5 is made of elastic material, it achieves the effect of buffering the bottom end of the first spring column 22 and improving the working life of the first spring column 22.

[0031] Furthermore, such as Figure 3 As shown, a friction ring 6 is fixed to the outer wall of the second rotating wheel 33. During operation, when the second rotating wheel 33 contacts the ground, the friction ring 6 deforms accordingly. Since the friction ring 6 is made of elastic material, the occurrence of severe wear caused by prolonged contact between the outer wall of the second rotating wheel 33 and the ground is reduced.

[0032] Furthermore, such as Figure 2 As shown, a locking block 7 is fixedly connected to the end of the connecting rod 25 away from the locking post 24; the locking block 7 is located above the rotating shaft 21; during operation, the locking block 7 can restrict the movement range of the connecting rod 25 inside the limiting ring 26, thereby reducing the occurrence of the connecting rod 25 falling off from the inside of the limiting ring 26.

[0033] Working principle: During operation, the operator can move the first rotating wheel 15, which in turn moves the distribution box body 1, via the handle 11. When the first rotating wheel 15 is compressed, it pushes the threaded rod 16 upward. Because the threaded rod 16 and the threaded rotating column 18 are threadedly connected, the return spring 19 deforms. When the distribution box body 1 passes over a concave surface, the first rotating wheel 15 is no longer under pressure, and the deformed return spring 19 can drive the first rotating wheel 15 downward via the threaded rotating column 18, thus bringing the first rotating wheel 15 into contact with the ground. The overall device improves the stability of the distribution box body 1 during movement and enhances its adaptability when passing over concave and convex surfaces; it also reduces the impact of the distribution box... Significant vibration of the main body 1 could damage internal parts. During operation, the operator rotates the shaft 21 to maintain a suitable contact angle between the bottom of the first spring column 22 and the ground. The connecting rod 25 can be moved via the limit ring 26, causing the locking column 24 and the limit sleeve 23 to engage, thus fixing the adjusted shaft 21. When the distribution box 1 tilts, the pair of first spring columns 22 can contact the ground and retract inwards towards the shaft 21, improving the cushioning effect and reducing the risk of damage to parts after the distribution box 1 tilts. During operation, when the first spring column 22 contacts the ground... When the first spring post 22 is housed inside the rotating shaft 21, it drives the first gear 31 to rotate via the tooth groove 3. The rotating first gear 31, through the second gear 32, can drive the second rotating wheel 33 to move downward, so that the outer wall of the second rotating wheel 33 contacts the ground, thereby achieving the effect of supporting the tilted distribution box body 1. The second rotating wheel 33 can also rotate. The overall device improves the stability of the distribution box body 1 when it moves. During operation, the second spring post 41 can drive the connecting rod 25 to move towards the rotating shaft 21 via the limiting ring 26 through the second fixed seat 4, so that the locking post 24 and the limiting sleeve post 23 are always engaged when not operated by the operator, thereby improving the fixation of the rotating shaft 21. The timing is stable; during operation, before the bottom of the first spring column 22 contacts the ground, the protective soft plate 5 contacts the ground first, and because the protective soft plate 5 is made of elastic material, it achieves the effect of buffering the bottom of the first spring column 22, thereby improving the service life of the first spring column 22; during operation, when the second rotating wheel 33 contacts the ground, the friction ring 6 deforms accordingly, and because the friction ring 6 is made of elastic material, it reduces the occurrence of severe wear caused by prolonged contact between the outer wall of the second rotating wheel 33 and the ground; during operation, the locking block 7 can limit the movement range of the connecting rod 25 inside the limiting ring 26, thereby reducing the occurrence of the connecting rod 25 falling off from the inside of the limiting ring 26.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
