Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a be fit for flat push rod case, the power distribution box comprises a box body 13, box 13 is provided with two altogether, and the bottom is passed through the hinge and is rotated the connection between two boxes 13, the inside bottom of box 13 is provided with prevents down board 3, and prevent down board 3 through the spout 1 that inside was seted up and the inboard fixed connection's of box 13 spacing lug 4 sliding connection, the top of preventing down board 3 rotates through connecting rod 9 and is connected with dead lever 7, and the top fixedly connected with reset plate 6 of dead lever 7, and through extrusion spring I8 elastic connection between reset plate 6 and the box 13, the inside of box 13 just is located reset plate 6 and is provided with telescope tube 18 directly over, the pull rod 16 that runs through box 13 is inlayed at the top of telescope tube 18.

Through adopting above-mentioned technical scheme, through the setting of spacing lug 4 for prevent falling board 3 at the in-process that rises or descend, remove according to certain orbit, thereby prevent falling board 3 skew, and after preventing falling board 3 bottom atress, spacing lug 4 of accessible is to preventing that falling board 3 carries on spacingly.

Specifically, as shown in fig. 1 to 3, two fall-preventing plates 3 are provided, the two fall-preventing plates 3 are respectively located at the front side and the rear side of the box body 13, and the bottom ends of the fall-preventing plates 3 are provided with the rollers 2.

Through adopting above-mentioned technical scheme, through the setting of a plurality of boards 3 of falling of preventing for box 13 is at the in-process that the flat push was pushed, if the slope takes place, and backup pad 3's holding surface is bigger, and stability is higher.

Specifically, as shown in fig. 1 and 2, the inside diapire of box 13 is the inclined plane structure, and the inclined plane with prevent the diapire laminating of falling board 3, prevent falling board 3 and run through the outer wall of box 13 through leading to groove 5, universal wheel 23 is all installed to the bottom corner of box 13.

Through adopting above-mentioned technical scheme, through the inclined plane setting of box 13 bottom, after the bottom atress of preventing falling board 3, under spacing lug 4's effect, will form the lever, and box 13's ground will carry out the atress to the bottom of preventing falling board 3 in the time, has improved the stability of preventing falling board 3.

Specifically, as shown in fig. 1, the two ends of the connecting rod 9 are rotatably connected with the fixing rod 7 and the falling prevention plate 3 through pin shafts, and the two sides of the bottom of the return plate 6 are elastically connected with the convex plate fixedly connected to the inner wall of the box body 13 through the extrusion spring I8.

Through adopting above-mentioned technical scheme, realize dead lever 7 when promoting anti-falling plate 3 through connecting rod 9, can take place relative rotation between the two.

Specifically, as shown in fig. 1-3, the bottom fixedly connected with stopper 20 of telescopic sleeve 18, a plurality of recesses 22 have all been seted up to stopper 20's inside both sides, and the inner wall of recess 22 all has bolt 21 through extrusion spring II19 elastic connection, has seted up a plurality of draw-in grooves 17 that use with bolt 21 cooperation along vertical end in proper order on the inner wall of box 13, and handle 15 is installed at the top of pull rod 16.

Through adopting above-mentioned technical scheme, through the setting of draw-in groove 17 for handle 15 can be relatively fixed after promoting anti-falling plate 3, and make handle 15 when need not the use, can be restricted in certain position, form the function of accomodating.

Specifically, as shown in fig. 1 and 4, four corners of a vertical surface of an inner cavity of the box 13 are fixedly connected with sliding rods 11, sliding sleeves 10 are sleeved outside the sliding rods 11, the sliding sleeves 10 are elastically connected with the inner wall of the box 13 through extension springs 14, the extension springs 14 are located on the periphery of the sliding rods 11, and elastic cloth 24 is fixedly connected between the four sliding sleeves 10.

By adopting the technical scheme, the elastic cloth 24 can drive the sliding sleeve 10 to slide, and the elastic coefficient of the extension spring 14 is unchanged, so that the tensile force generated by the elastic cloth 24 is also constant, and articles in the box body 13 can be better protected.

Specifically, as shown in fig. 1, a strong magnet 12 is fixedly connected to the end of the sliding rod 11, and the strong magnets 12 inside the two cases 13 attract each other.

Through adopting above-mentioned technical scheme, strong magnet 12 can be connected two boxes 13, and because box 13 is inside to have certain weight, and the bottom of box 13 is passed through the hinge and is rotated the connection, so in the in-process of in-service use, two strong magnets 12 have the trend of motion that is close to each other, consequently through the connection of strong magnet 12, can realize the connection to box 13, and when needs are opened, because the closure of box 13 forms with the help of the weight of box 13 body, so when opening box 13, the dynamics of using will be obviously less than the closed dynamics of box 13, make the user can be easily opened box 13.

One specific application of this embodiment is:

when the trolley is used, when articles need to be stored in the trolley case 13, the four sliding sleeves 10 are driven to slide on the sliding rods 11 by pulling the elastic cloth 24, so that a gap exists between the elastic cloth 24 and the case body 13, the articles are placed between the case body 13 and the elastic cloth 24, then the elastic cloth 24 is loosened, the sliding sleeves 10 slide on the sliding rods 11 under the action of the extension springs 14, so that the elastic cloth 24 is attached to the outer surfaces of the articles, and the articles are fixed, and compared with the traditional mode of directly using the elastic cloth 24, the trolley is more stable in tension, and the positions of the four sliding sleeves 10 are relatively fixed, so that the stability of the elastic cloth 24 is higher, and the articles are better protected; after loading is finished, the two box bodies 13 are closed through rotation of the hinge, after the two box bodies are closed, the two groups of strong magnets 12 attract each other, and therefore connection and fixation of the two box bodies 13 are achieved, compared with a traditional mode of connection through a buckle, the operation is simpler and more convenient through the mode of connection through the strong magnets 12, and when the box bodies need to be opened, the two box bodies 13 can be directly pulled outwards; when the flat push is needed, firstly, one side needing the flat push is selected, then the handle 15 on the other side is pressed downwards, the telescopic sleeve 18 drives the limiting block 20 to move downwards, after the limiting block 20 is attached to the top of the reset plate 6, the falling prevention plate 3 is continuously pushed downwards through the fixed rod 7 and the connecting rod 9, the falling prevention plate 3 slides outwards under the support of the inclined plane at the bottom of the box body 13 under the matching of the limiting lug 4 and the sliding groove 1 until the roller 2 is contacted with the ground, the bolt 21 is inserted into the groove 22 under the action of the extrusion spring II19 so as to fix the limiting block 20, meanwhile, the position of the falling prevention plate 3 is also fixed, in the process of flat pushing the box body 13, when the box body 13 is inclined, the roller 2 at the bottom of the falling prevention plate 3 can support the box body 13 again, the stability of the box body 13 is guaranteed, when the falling prevention plate 13 is not needed, the limiting block 20 is pulled out upwards through the handle 15, the anti-falling plate 3 moves upwards under the action of the extrusion spring I8 and enters the box body 13, and the storage function is achieved.
