Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, and particularly relates to a multifunctional mobile distribution box. Background Art

[0002] A distribution box is an electrical device that can be used for short-circuit protection, overload protection, and leakage protection. It can also distribute electric energy orderly and reasonably to each electrical device. Moreover, through components such as circuit breakers and contactors inside the distribution box, the control of various different electrical devices can be realized.

[0003] During the process of tunnel construction, distribution boxes are often used. Due to the uneven ground of the tunnel, slide rails are often installed on the side walls of the tunnel, and the flexible movement of the distribution box is realized through the slide rails. However, there are still the following defects: the slide rails are only used for moving the distribution box. If they are used to move other devices, interference will occur with the distribution box. Unless multiple parallel slide rails are set, but the spacing needs to be kept large (to avoid interference between other devices and the distribution box), which is costly and occupies too much space, and the effect is not good. Summary of the Utility Model

[0004] Therefore, the utility model provides a multifunctional mobile distribution box to solve the above problems in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1 to 6 shown, a multifunctional mobile distribution box in the first aspect embodiment of the present utility model includes a plurality of L-shaped steel frames 10 installed on the tunnel sidewall. The bottom end of each L-shaped steel frame 10 is provided with a first slide rail 20. Adjacent two first slide rails 20 are connected by series bolts. The bottom end of each L-shaped steel frame 10 is bolted with a second slide rail 30. The second slide rail 30 is located directly in front of the first slide rail 20. The top surface of the L-shaped steel frame 10 is provided with a strengthening and fastening mechanism 40. A square slider 50 is slidably connected to one of the second slide rails 30. The square slider 50 can be slidably connected to the first slide rail 20. Long openings 60 are formed on the top surfaces of the second slide rail 30 and the L-shaped steel frame 10. A first elastic clamping block 70 is clamped on the top surface of the square slider 50. A groove 80 matching the strengthening and fastening mechanism 40 is formed on the back surface of the first elastic clamping block 70. A pushing and fastening mechanism 90 is arranged on the square slider 50. Four suspension ropes 100 are fixedly connected to the bottom end of the square slider 50. The bottom end of the suspension ropes 100 is fixedly connected to a distribution box body 110;

[0026] In the above embodiment, it should be noted that a plurality of balls are embedded on the upper and lower surfaces of the square slider 50, which can effectively reduce the frictional resistance generated when the square slider 50 slides in the first slide rail 20 and the second slide rail 30, and the movement is more relaxed and smooth;

[0027] The technical effect achieved by the above embodiment is: under the action of the square slider 50, the distribution box body 110 can be driven to slide freely and flexibly on the first slide rail 20 and the second slide rail 30. Under normal circumstances, the distribution box body 110 is staggered with the first slide rail 20. At this time, the first slide rail 20 can be used for the flexible movement of other equipment. The first slide rail 20 can be fully utilized without causing waste of resources, which can improve the actual use experience.

[0028] Example 2

[0029] like Figures 1 to 6 As shown, a multifunctional mobile distribution box includes all the contents of Example 1. In addition, the strengthening and fastening mechanism 40 includes a pair of reinforcing ribs 410 welded to the top surface of the L-shaped steel frame 10, and the two reinforcing ribs 410 are provided with a slide groove 411 on the side close to each other, and a hollow slider 412 is connected between the two slide grooves 411 in an inclined sliding manner. A tension spring 413 welded to the L-shaped steel frame 10 is welded to the rear end of the hollow slider 412. A clamping groove 414 is provided on the side away from each other of the two slide grooves 411. The second elastic clamping block 415 is clamped on both sides of the hollow slider 412. The front inner wall of the hollow slider 412 slides forward and backward. The front end of the slide bar 416 is fixedly connected with a pull rope 418, and the other end of the pull rope 418 is fixedly connected with the front end of the hollow slider 412. The front end of the hollow slider 412 is integrally connected with a top plate 419. A pair of guide holes 200 extending to the top surface of the L-shaped steel frame 10 are provided on the front side of the L-shaped steel frame 10. The pull rope 418 passes through the two guide holes 200. Two guide wheels 210 connected to the upper and lower inner wall shafts of the hollow slider 412 are provided in the hollow slider 412, and the pull rope 417 is wound around the guide wheel 210.

[0030] In the above embodiment, it should be noted that the reinforcing rib 410 and the slide groove 411 are both inclined, and the tension spring 413 plays an elastic pulling role. After the second elastic block 415 is stored, it maintains a large distance with the slot 414. After the pull rope 418 is released, the hollow slider 412 tilts upward for a distance, and then the second elastic block 415 is unfolded and fits with the inner wall of the slide groove 411, which will not affect the subsequent tilting and sliding reset of the hollow slider 412.

[0031] The technical effect achieved by the above embodiment is: the reinforcing rib 410 can further improve the strength of the L-shaped steel frame 10, withstand high pressure without breaking or bending, and at the same time can realize the fastening and locking of the upper slider 50 of the second slide rail 30, providing a basis for the subsequent stability of the distribution box body 110.

[0032] Example 3

[0033] like Figures 1 to 6As shown, a multifunctional mobile distribution box includes all the contents of embodiment 2, in addition, the first elastic block 70 and the second elastic block 415 have the same structure, and the front end of the top plate 419 is pressed against the front inner wall of the groove 80;

[0034] In the above embodiment, it should be noted that the first elastic block 70 and the second elastic block 415 are both composed of right-angle trapezoidal blocks and springs.

[0035] The technical effect achieved by the above embodiment is: the relationship between the top plate 419 and the groove 80 is disclosed, and the top plate 419 is pressed against the groove 80. At this time, the first elastic block 70 will not be squeezed and moved downward, so that the square slider 50 can be squeezed and locked.

[0036] Example 4

[0037] like Figures 1 to 6 As shown, a multifunctional mobile distribution box includes all the contents of Example 3. In addition, the pushing and fastening mechanism 90 includes a pair of push rods 91 integrally connected to both sides of the square slider 50, and the top surface of the push rods 91 is provided with a through hole 92. The square slider 50 is provided with a limit groove extending into the two push rods 91, and the limit groove is provided with two clamping long plates 93 connected to the front and rear sliding. Both ends of the two clamping long plates 93 extend into the through hole 92, and the front rotation connection of the square slider 50 A threaded rotating rod 94 is connected, the rear end of the threaded rotating rod 94 is rotatably connected to the rear inner wall of the limiting groove, the two clamping long plates 93 are both threadedly connected to the threaded rotating rod 94, two long strips 95 are welded on the top surface of the distribution box body 110, and the two long strips 95 respectively penetrate the two through-holes 92, the threaded rotating rod 94 is a left and right threaded rod, and the top surface level of the long strip 95 is lower than the bottom surface level of the first slide rail 20, and the ends of the two push rods 91 away from each other are welded with handrails, and the handrails are perpendicular to the push rods 91;

[0038] In the above embodiment, it should be noted that the armrest on the push rod 91 is wrapped with a rubber sleeve to facilitate the pushing of relevant staff;

[0039] The technical effect achieved by the above embodiment is as follows: due to the use of the suspension rope 100, the distribution box body 110 is always vertically downward, and the two clamping long plates 93 can be driven to move closer to each other by the forward-rotating threaded rod 94 to clamp and fix the long strip 95. At this time, the distribution box body 110 is firm and stable, and there will be no large shaking, and the working stability is greatly improved.

[0040] Working principle: For example, when further excavating a tunnel, in order to avoid the contact between flying stones and the distribution box, the distance of the distribution box needs to be adjusted farther. Reverse the threaded rod 94 to separate the clamping long plate 93 from the long strip 95, and then pull the pull rope 418 (the end connected to the slide bar 416). At this time, the slide bar 416 moves forward and pulls the two traction ropes 417. The two second elastic blocks 415 are received and separated from the card slots 414. Release the pull rope 418. Under the elastic pull of the tension spring 413, the entire hollow slide block 412 tilts and moves upward, and the square slide block 50 is moved backward to the first slide rail 20 through the push rod 91 (at this time, the first elastic block 70 touches the inner wall of the rear side of the long opening 60 and is automatically elastically received), and then the distribution box is adjusted to a suitable position along the first slide rail 20. Slide the square slide block 50 into the second slide rail 30. When the first elastic block 70 is directly below the long opening 60, the first elastic block 70 loses its limit and automatically protrudes and extends into the long opening 60. Pull the pull rope 418 (the end fixedly connected to the front of the hollow slide block 412), which can drive the hollow slide block 412 to tilt and slide down along the chute 411 until the second elastic block 415 is elastically clamped on the card slot 414. At the same time, the top plate 419 tightly presses against the groove 80 on the first elastic block 70, which can lock the square slide block 50. Finally, rotate the threaded rod 94 forward to drive the two clamping long plates 93 to approach each other. At this time, the two clamping long plates 93 can clamp and fix the long strip 95. At this time, the distribution box body 110 is firm and stable, without large shaking, and the working stability is greatly improved accordingly.
