[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figure 1-4 As shown, this utility model provides a unit bracket handling device that facilitates docking, including a first bracket 1 and a second bracket 2. Universal wheels 3 are bolted to the bottom of both the first bracket 1 and the bottom of both the second bracket 2. The first bracket 1 and the second bracket 2 are docked and interlocked to adjust the width of the first bracket 1 and the second bracket 2. Locking fasteners are installed on both sides of the first bracket 1 to lock and fix the width distance between the first bracket 1 and the second bracket 2. Support members are fixedly installed on both sides of the first bracket 1 and both sides of the second bracket 2 to support and fix the first bracket 1 and the second bracket 2. Reinforcing ribs 22 are fixedly installed on one side of the first bracket 1 and one side of the second bracket 2.

[0022] It should be added that both the first support 1 and the second support 2 have an L-shaped cross section. The reinforcing rib 22 can increase the compressive strength of the first support 1 and the second support 2. The casters 3 at the bottom of the first support 1 and the second support 2 can facilitate the insertion of the first support 1 and the second support 2 to carry goods for transfer. After the first support 1 and the second support 2 are inserted, the width can be adjusted. Then, the locking fasteners can be used to lock and fix the first support 1 and the second support 2. Four sets of support members can support and fix the first support 1 and the second support 2 to facilitate the loading of goods, prevent the first support 1 and the second support 2 from shifting or shaking, and improve the stability of fixing the first support 1 and the second support 2.

[0023] Specifically, an insertion plate 4 is fixedly connected to one side of the first bracket 1, and a notch 5 is opened on the other side of the second bracket 2. A pad 6 is fixedly installed at the bottom of the first bracket 1 and at the bottom of the insertion plate 4. The insertion plate 4 and the notch 5 are slidably connected by insertion. Limiting parts 20 are fixedly connected to both sides of the insertion plate 4. Limiting grooves 21 are opened on both sides of the notch 5. The limiting parts 20 and the limiting grooves 21 are slidably connected.

[0024] When the first support 1 and the second support 2 are spliced, the insertion plate 4 is inserted into the notch 5, and the limiting part 20 on both sides of the insertion plate 4 and located in the middle is inserted into the limiting groove 21, which can limit and guide the first support 1 and the second support 2. The pad 6 at the bottom of the first support 1 can support the second support 2 again, increasing the compressive strength of the first support 1 and the second support 2 when they are spliced ​​together to hold goods.

[0025] More specifically, the locking mechanism includes movable cavities 7 respectively opened on both sides of the insertion plate 4, a screw 8 screwed into the inner side of the movable cavity 7, a fixing part 10 for supporting the connecting plate 9 installed on the outer side of the screw 8 near one end, a locking post 11 fixedly connected to one side of the connecting plate 9 near both ends, a plurality of evenly arranged locking slots 12 opened on both sides of the second bracket 2 and on both sides of the notch 5, the fixing part 10 is rotatably connected to the connecting plate 9 and does not detach, a spring 17 is sleeved on the outer side of the screw 8, a washer 18 is fixedly installed on one end of the spring 17, an anti-detachment part 19 is fixedly connected to one end of the screw 8, and the two ends of the spring 17 are fixedly connected to the movable cavity 7 and the washer 18 respectively.

[0026] In addition, the screw 8 can rotate screwed inside the movable cavity 7. The screw 8 can drive the connecting plate 9 to move through the fixing part 10, so that the connecting plate 9 can drive the two locking pins 11 to insert or disengage from the locking groove 12, so that the insertion plate 4 can be inserted into the notch 5 to lock and fix the first bracket 1 and the second bracket 2. The spring 17 on the outside of the screw 8 can compress the washer 18, and then the washer 18 can compress and push the anti-disengagement part 19 to increase the strength of the locking pin 11 inserted into the locking groove 12.

[0027] Furthermore, the support includes telescopic arms 13 that are fixedly installed on both sides of the first bracket 1 and the second bracket 2 respectively. A hydraulic cylinder 14 is fixedly installed on the top of the telescopic arm 13, a telescopic rod 15 is fixedly installed on the bottom of the hydraulic cylinder 14, and a pad 16 is fixedly installed on the bottom of the telescopic rod 15.

[0028] The telescopic arm 13 is a hydraulic telescopic crossarm. The telescopic arm 13 can drive the hydraulic cylinder 14 to extend or retract, so as to adjust the support area of ​​the pad 16. The hydraulic cylinder 14 can drive the pad 16 to move up and down through the telescopic rod 15, so that the four pads 16 support the first bracket 1 and the second bracket 2, preventing the first bracket 1 and the second bracket 2 from shifting or shaking.

[0029] Working principle: First, the first bracket 1 and the second bracket 2 are spliced ​​together. At the same time, the insertion plate 4 is inserted into the notch 5, and the limiting parts 20 on both sides of the insertion plate 4 and located in the middle are inserted into the limiting groove 21. The pad 6 at the bottom of the first bracket 1 supports the second bracket 2 again. Then, the screw 8 is rotated so that it rotates screwed inside the movable cavity 7. At the same time, the screw 8 drives the connecting plate 9 to move through the fixing part 10. At this time, the connecting plate 9 drives the two locking pins 11 to insert into the locking groove 12. At the same time, the spring 17 on the outside of the screw 8 squeezes the washer 18. Then the washer 18 squeezes and pushes the anti-detachment part 19 so that the insertion plate 4 can be inserted into the notch 5 to lock and fix the first bracket 1 and the second bracket 2.
