A volume-variable box

Abstract

The utility model discloses a volume-variable box, which relates to the technical field of battery assembly and solves the problem that photovoltaic cleaning robots with different battery life need to be matched with different photovoltaic power station string lengths, while batteries with different capacities have different sizes, which makes it difficult to unify the specifications of the battery box, thereby increasing the use cost of the photovoltaic cleaning robot. The volume-variable box comprises a first sub-box, a bellows-type telescopic cylinder, a second sub-box, and a telescopic adjustment part. By changing the position of an adjusting nut, pulling and pulling a screw rod, and changing the length of the telescopic adjustment part, the length of the bellows-type telescopic cylinder can be quickly changed, thereby changing the volume of the variable box, allowing the photovoltaic cleaning robot to better adapt to batteries of different capacities during work. The screw rod and the bellows-type telescopic cylinder can be fixed by the adjusting nut, so that the volume of the volume-variable box is fixed, thereby preventing the battery from shaking in the variable box when working.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, a volume-variable box body comprises a first sub-box body 1, a bellows-type telescopic cylinder body 2 and a second sub-box body 3; a connecting portion is respectively provided on one side of the first sub-box body 1 and the second sub-box body 3; and a connecting portion is provided on both ends of the bellows-type telescopic cylinder body 2; wherein the two connecting portions of the bellows-type telescopic cylinder body 2 are respectively connected to the connecting portions of the first sub-box body 1 and the second sub-box body 3 by bolts;

[0027] like Figure 1 and Figure 3 As shown, it can be known that the bellows telescopic cylinder 2 also includes a telescopic bellows 4, at least one telescopic rod 5 and at least one telescopic adjustment part 6; wherein, the two ends of the telescopic bellows 4 are respectively fixedly connected to the two connecting parts of the bellows telescopic cylinder 2; the telescopic rod 5 includes at least one external rod and a plurality of internal rods, and the internal rods are slidably sleeved on the inner side of the external rods; and one end of the external rod is fixed to the connecting part of the bellows telescopic cylinder 2; it should be noted that the external rod and the connecting part can be fixed by welding, threaded connection or riveting; one end of the internal rod is fixed to the other connecting part of the bellows telescopic cylinder 2; obviously, the internal rod and the connecting part can be fixed by welding, threaded connection or riveting;

[0028] It should be noted that the end of the inner rod and the end of the outer rod fixed to the connecting portion are the two ends of the telescopic rod 5 respectively;

[0029] like Figure 2 As shown, the telescopic adjustment part 6 includes a connecting rod 7, an adjusting nut 10, a screw rod 8 and a connecting block 9; one end of the connecting rod 7 is fixedly mounted with the connecting block 9, and the other end is fixedly mounted on the connecting part of the corrugated telescopic cylinder 2;

[0030] The connecting block 9 is provided with a telescopic adjustment hole; one end of the screw rod 8 is fixed to the connecting portion away from the connecting rod 7 and passes through the telescopic adjustment hole along the telescopic direction of the corrugated telescopic cylinder 2;

[0031] The adjusting nut 10 is sleeved on the screw rod 8 and is located on both sides of the connecting block 9; in operation, when the adjusting nut 10 is spirally moved toward the second sub-box body 3, the screw rod 8 is pulled in the opposite direction, driving the inner rod of the telescopic rod 5 and the telescopic bellows 4 to stretch, so that the volume of the corrugated telescopic cylinder 2 becomes larger; when the adjusting nut 10 is spirally moved toward the first sub-box body 1, the screw 8 is pushed in the opposite direction, driving the inner rod of the telescopic rod 5 and the telescopic bellows 4 to compress, so that the volume of the corrugated telescopic cylinder 2 becomes smaller. It should be noted that after the length of the telescopic adjusting part 6 is adjusted, the adjusting nuts 10 on both sides of the connecting block 9 lock the screw 8 and the connecting block 9;

[0032] By changing the position of the adjusting nut 10, the length of the telescopic adjusting part 6 is changed, so that the length of the corrugated telescopic cylinder 2 can be changed quickly, thereby changing the volume of the variable volume box;

[0033] The second sub-box body 3 is further provided with at least one threaded block 11, a box opening 13 and a box cover 12 on a side away from the first sub-box body 1. The threaded block 11 and the second sub-box body 3 may be connected by welding or riveting.

[0034] The box cover 12 is connected to the threaded block 11 by bolts, and a sealing strip is provided at the part where the box cover 12 and the box opening 13 are in contact, so that the box body forms a good closed space, which prevents dust and water stains from entering during operation, avoids affecting the batteries installed in the box, and enables the machine to work stably;

[0035] The first sub-box body 1 also includes a reserved plug hole 14, in which a waterproof aviation plug can be provided, which is more conducive to charging the battery in the bottom of the box at any time, thereby improving the battery life;

[0036] The working principle of the utility model: in operation, when the adjusting nut 10 moves spirally toward the second sub-box 3, the screw 8 is pulled in the opposite direction, driving the inner rod of the telescopic rod 5 and the telescopic bellows 4 to stretch, so that the length of the bellows telescopic cylinder 2 becomes longer, and the volume of the variable box is increased;

[0037] When the adjusting nut 10 moves spirally toward the first sub-box 1, the screw 8 pushes in the opposite direction, driving the inner rod of the telescopic rod 5 and the telescopic bellows 4 to be compressed, so that the length of the bellows telescopic cylinder 2 becomes shorter, reducing the volume of the variable box;

[0038] After the length of the telescopic adjustment part 6 is adjusted, the adjusting nuts 10 on both sides of the connection part fix and lock the screw rod 8 and the connection block 9, so that the length of the telescopic adjustment part 6 no longer changes, and the volume of the variable box is fixed;

[0039] By changing the position of the adjusting nut 10 and changing the length of the telescopic adjusting part 6, the length of the corrugated telescopic cylinder 2 can be quickly changed, thereby changing the volume of the variable box, and batteries of different sizes can be installed during work, so that the box can adapt to batteries of different specifications.

[0040] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
