DETAILED DESCRIPTION

[0022] Please refer to Figures 1-5 The utility model provides a technical scheme: a jumping box convenient to assemble, including box one 1 and box two 2, box two 2 installs on the upper surface of box one 1, the upper surface of box two 2 is installed with box three 3, the upper surface of box three 3 is fixedly connected with flexible base plate 4, and the inside of box one 1, box two 2 and box three 3 are all provided with assembly component 5.

[0023] In this embodiment: Assembly component 5 includes locking unit 51, locking unit 51 includes mounting sleeve 512, support plate 511 is fixedly connected to the inner wall of box 1, box 2 and box 3, mounting sleeve 512 is fixedly connected to the side surface of support plate 511, insert plate 513 is fixedly connected to the inner wall of box 2 and box 3, slider 514 is slidably connected to the inner wall of mounting sleeve 512, limit spring 515 is fixedly connected to the side surface of slider 514, the side of limit spring 515 away from slider 514 is fixedly connected to the inner wall of mounting sleeve 512, and locking pin 516 is fixedly connected to the side of slider 514 away from limit spring 515. Fixing hole 517 is opened on the surface of insert plate 513, and locking pin 516 is inserted into the inner wall of fixing hole 517.

[0024] Specifically, assembly component 5 also includes a pulling unit 52, which includes a connecting rod 521. The connecting rod 521 is fixedly connected to the side surface of the slider 514 and slidably connected to the inner wall of the mounting sleeve 512. A U-shaped frame 522 is fixedly connected to the end of the connecting rod 521 away from the slider 514. A connecting arm 523 is rotatably connected to the inner wall of the U-shaped frame 522, and a pull rod 524 is rotatably connected to the end of the connecting arm 523 away from the U-shaped frame 522.

[0025] Specifically, there are two support plates 511. The two support plates 511 are arranged symmetrically about the vertical center line of the box 1. Square holes are opened on the surface of the support plates 511, and the support plates 511 are fitted onto the surface of the locking pin 516 through the square holes.

[0026] In this embodiment, the interior of the box 1 can be reinforced by the support plate 511 to increase the structural strength of the box 1.

[0027] Specifically, the insert plate 513 contacts the side surface of the support plate 511. The lower end of the insert plate 513 near the support plate 511 is chamfered. When the insert plate 513 comes into contact with the surface of the support plate 511, it can work with the latch 516 and the fixing hole 517 to lock the same two above the box 1.

[0028] In this embodiment, there are two limiting springs 515, which are arranged symmetrically about the vertical center line of the slider 514.

[0029] In this embodiment, the position of the slider 514 can be constrained by the limiting spring 515 to ensure the stability of the slider 514 in the locked state.

[0030] Specifically, the upper end of the locking pin 516 on the side away from the slider 514 is chamfered, and the locking pin 516 can lock the position of the insert plate 513 when it is inserted into the fixing hole 517.

[0031] Specifically, both ends of the connecting arm 523 are arc-shaped.

[0032] In this embodiment: the U-shaped frame 522 and the pull rod 524 are connected through the connecting arm 523 to realize the linkage effect between them.

[0033] Working principle: when assembling the jump box, place box one 1 on the ground, then align box two 2 above box one 1, and push down box two 2, which pushes the plug-in plate 513, and the plug-in plate 513 moves downward. During the movement of the plug-in plate 513, the inclined surface thereof contacts the inclined surface of the locking pin 516 and extrudes the locking pin 516 in the direction of the sliding block 514, and the locking pin 516 slides into the mounting sleeve 512 and pushes the sliding block 514, which extrudes the limiting spring 515. Continue to push down box two 2, so that the plug-in plate 513 moves downward, and when the lower end of box two 2 contacts the upper end of box one 1, the fixing hole 517 on the surface of the plug-in plate 513 overlaps the locking pin 516, and at the same time the plug-in plate 513 loses the restraint of the locking pin 516, the locking pin 516 loses the pressure on the sliding block 514, the sliding block 514 loses the pressure exerted by the limiting spring 515, and the limiting spring 515 loses the pressure and rebounds, and cooperates with the sliding block 514 to push the locking pin 516 into the fixing hole 517 to lock the position of the plug-in plate 513. Then install box three 3 on the upper end of box two 2 according to the above steps.

[0034] When the jump box needs to be disassembled, place the jump box upside down and pull the pull rod 524 in box one 1 from the lower opening of box one 1, and the pull rod 524 is pulled by the force to pull the connecting arm 523, which cooperates with the U-shaped frame 522 to pull the connecting rod 521, and the connecting rod 521 pulls the sliding block 514, which pulls the locking pin 516 by force, so that the locking pin 516 is separated from the fixing hole 517 and loses the locking of the plug-in plate 513. When the plug-in plate 513 loses the locking, box one 1 can be disassembled, and then box two 2 can be disassembled from box three 3 according to the above steps. By setting the assembly component 5, the jump box can be assembled conveniently, and the firmness of the connection position of the jump box can be ensured, thereby reducing the problem that the connection position of the jump box is prone to separation when using a fixed plate and an elastic band, which causes safety hazards of the jump box, and further improving the safety of the jump box.
