The working principle of the invention is as follows:

referring to the attached fig. 1-4 of the specification, when the whole pallet needs to be used for consignment of goods, the whole pallet needs to be spliced and assembled. Assemble into a tray frame with a concatenation dish 1 and a bottom plate 2 earlier, after the thread groove threaded connection with the 3 bottoms of spacing post and 2 top surfaces of bottom plate, inject spacing post 3 at 2 tops of bottom plate, utilize ring cover frame 7 to cup joint behind 3 surfaces of spacing post to place buffer at 2 tops of bottom plate, with the flitch 10 of bottom and the laminating of 2 top surfaces of bottom plate, then install concatenation dish 1. Utilize through-hole 4 to correspond with spacing post 3, then place assembly tray 1 at bottom plate 2 tops, flitch 10 and the laminating of assembly tray 1 bottom surface at top this moment, then inject assembly tray 1's position. Second spring 17 cup joints behind U type frame 15 surface, correspond the kink and the through-hole 4 of U type frame 15 and put the back, press the concatenation dish 1, concatenation dish 1 extrudees buffer, 3 tops of spacing post drive U type frame 15 shifts up, make U type frame 15 tip stretch out through-hole 4 top, peg graft behind U type frame 15 top is inside movable groove 16, rotate turning block 14, turning block 14 makes turning block 14 get into through-hole 4 inside gradually with the spiral effect of through-hole 4, when rotating block 14 rotates, relax the pressure to concatenation dish 1 gradually, it is inside until turning block 14 gets into through-hole 4 completely, loosen concatenation dish 1, utilize the elasticity of second spring 17 to make 3 tops of spacing post correspond the laminating with U type frame 15 kink, accomplish the installation to a tray frame this moment.

When assembling the tray frame, thereby can adjust connecting device according to the position of calorie hole 5, correspond the laminating with two tray frame sides and place, rotate and change cover 24, change cover 24 and stop screw 25's spiral effect and make and go up and move head 18 at stop screw 25 surface slip, thereby adjust two distances of going up between moving head 18 according to the distance between two adjacent calorie holes 5 of two tray frames this moment, thereby make things convenient for nose bar 6 and calorie hole 5 to correspond the buckle and assemble two adjacent concatenation dishes 1. Thereby the distance between the card hole 5 of the inside concatenation dish 1 of a tray frame and the card hole 5 of bottom plate 2 moves the head 18 and moves down the distance between the head 19 on the adjustment, screw rod 23 is twisted out, it moves down the head 19 and removes to promote, sliding sleeve 21 slides at link 20 tip this moment, when the protruding pole 6 of moving head 18 and the protruding pole 6 of moving head 19 down correspond the buckle with the card hole 5 of concatenation dish 1 and bottom plate 2 respectively, move the exact position of sliding sleeve 21 with ring 22, screw rod 23 is screwed up, make screw rod 23 tip pass through the screw and get into inside the sliding sleeve 21, screw rod 23 tip can prescribe a limit to link 20 side top this moment, can prevent to move the distance between head 18 and the head 19 down, and then avoid the distance between concatenation dish 1 and the bottom plate 2 to increase, make concatenation dish 1 prescribe a limit to bottom plate 2 top all the time. Thereby utilize a plurality of connecting device to connect a plurality of tray framves one-to-one, can assemble the tray of suitable size according to the volume of goods. Thereby can adjust connecting device according to the distance between 5 positions in the card hole and the amalgamation dish 1 and the bottom plate 2, increase connecting device's adaptation effect, guarantee the integration effect of whole tray simultaneously.

Place the goods when the tray top, the goods extrudees buffer through concatenation dish 1, go up revolving rack 8 and lower revolving rack 9 this moment and all use the pin joint of ring cover frame 7 as the centre of a circle to rotate, go up the contained angle between revolving rack 8 and the lower revolving rack 9 and reduce gradually, and go up revolving rack 8 and lower revolving rack 9 and all slide respectively in 1 bottom surface of concatenation dish and 2 top surfaces of bottom plate through flitch 10, go up revolving rack 8 and lower revolving rack 9 and extrude first spring 13, utilize the cushioning effect of the elasticity increase whole tray of first spring 13.

When the concatenation dish 1 moves down, 3 tops of relative spacing post shift up in through-hole 4 is inside, spacing post 3 promotes U type frame 15 when pressurizeing second spring 17 this moment, inside U type frame 15 top got into the movable groove 16 gradually, thereby it prescribes a limit to U type frame 15 position to change the spiral effect of piece 14 and through-hole 4, utilize second spring 17's elasticity to prevent that spacing post 3 top from shifting up too fast in through-hole 4 is inside, the buffering effect of whole tray has further been increased. The rotating block 14 can also prevent the top end of the limiting column 3 from extending out of the through hole 4, so that the limiting column 3 is prevented from ejecting the goods out of the splicing tray 1, and the stability of the goods at the top of the splicing tray 1 is ensured.

When the assembly dish 1 pushes down, the assembly dish 1 moves head 18 through 6 drives of nose bars and pushes down, moves head 18 on and moves down inside sliding sleeve 21 through link 20, guarantees the stability that whole tray moved down, and the corresponding effect of screw rod 23 and link 20 side can avoid the separation of assembly dish 1 and bottom plate 2, further increases the stability of whole tray.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
