Be equipped with the hydraulic pressure ejecting device who runs through stabilizer blade 2 on the up end of slide 4, hydraulic pressure ejecting device includes four first pneumatic cylinders 7, four first pneumatic cylinders 7 are fixed connection respectively on four slide 4's up end, be equipped with the through-hole on the up end of stabilizer blade 2, 7 sliding connection of first pneumatic cylinder are in the through-hole, two second pneumatic cylinders 12 of the bilateral symmetry fixedly connected with of first pneumatic cylinder 7, be equipped with first hydraulic pressure chamber 8 in the first pneumatic cylinder 7, sliding connection has piston 9 in the first hydraulic pressure chamber 8, fixedly connected with runs through the bracing piece 10 of first pneumatic cylinder 7 on the lateral wall of slide 4 is kept away from to piston 9.

One end fixed connection that piston 9 was kept away from to bracing piece 10 is on the bottom side wall of bearing board 11, all be equipped with second hydraulic chamber 13 in two second hydraulic cylinder 12, the bottom in second hydraulic chamber 13 and the bottom intercommunication in first hydraulic chamber 8, all pour into hydraulic oil into in first hydraulic chamber 8 and the second hydraulic chamber 13, second hydraulic cylinder 12 is close to the bottom of first pneumatic cylinder 7 one side and first pneumatic cylinder 7 and is close to the bottom of second hydraulic cylinder 12 one side and all is equipped with the water conservancy diversion hole, communicate each other through the water conservancy diversion hole between first hydraulic chamber 8 and the second hydraulic chamber 13.

First pneumatic cylinder 7 and second pneumatic cylinder 12 are in the same place through mode fixed connection of seal weld, sliding connection has slider 14 in the second hydraulic chamber 13, slider 14 keeps away from the one end fixed connection of slide 4 on the inside wall of cavity 3, all be equipped with seal ring on the lateral wall of piston 9 and slider 14, hydraulic ejection device's one serves fixedly connected with bearing board 11, place the goods on bearing board 11, under the pressure effect of goods to bearing board 11, bearing board 11 exerts a pressure effect for piston 9 through bracing piece 10, force piston 9 to move down along first hydraulic chamber 8, the extrusion hydraulic oil.

Make the hydraulic oil in the first hydraulic pressure chamber 8 follow the water conservancy diversion hole and get into second hydraulic pressure chamber 13, with the conduction medium of hydraulic oil as power, with the vertical decurrent pressure effect of piston 9 to hydraulic oil in the first hydraulic pressure chamber 8, convert the vertical ascending supporting force effect of hydraulic oil to slider 14 in the second hydraulic pressure chamber 13 into, thereby order to order about slider 14 along second hydraulic pressure chamber 13 rebound, and then drive rather than 2 upwards lifts of fixedly connected's stabilizer blade, make the 3 downstream of the relative cavity of slide 4, reset spring 5 is extruded, slide 4 drives universal wheel 6 and follows ejecting downthehole liftout, support subaerial, support layer board 11.

At this moment, can be with the help of universal wheel 6, this commodity circulation tray of convenient removal, take off the back with the goods from bearing board 11, under reset spring 5's elastic force effect, moving mechanism retracts in the cavity 3, stabilizer blade 2 supports subaerial, at this moment, whole device is supported by reset spring 5's elastic force effect, support with the help of stabilizer blade 2, be equipped with anti-skidding stripe on bearing board 11's the up end, anti-skidding threaded setting, help avoiding the commodity circulation tray the condition that the goods landing from bearing board 11 appears in the removal in-process, install stop device between bearing board 11 and the supporting baseplate 1.

Stop device includes that two are the solid fixed ring 15 that the symmetry set up, two solid fixed ring 15 equal fixed connection all rotate on the lateral wall that supporting baseplate 1 is close to bearing board 11 on the inner ring lateral wall of two solid fixed ring 15 and be connected with threaded rod 16, threaded rod 16 one serve fixedly connected with swing handle 17, sliding connection has first backing plate 18 on the up end of supporting baseplate 1, be equipped with the screw hole in first backing plate 18, threaded rod 16 threaded connection is in the screw hole, one side that swing handle 17 was kept away from to first backing plate 18 is the slope inclined plane setting.

Fixedly connected with second backing plate 19 on the bottom side wall of bearing board 11, one side that second backing plate 19 is close to swing handle 17 sets up to the slope inclined plane with first backing plate 18 assorted, the bottom of second backing plate 19 is equipped with recess 20, when need not use moving mechanism to remove this commodity circulation tray, can twist swing handle 17, it is rotatory to utilize swing handle 17 to drive threaded rod 16, thereby with the help of the threaded connection effect, order about first backing plate 18 and remove to second backing plate 19 direction along the last terminal surface of supporting baseplate 1, through the interact power between the slope inclined plane.

Because originally it is that universal wheel 6 is supporting whole commodity circulation tray, consequently second backing plate 19 can extrude first backing plate 18, makes first backing plate 18 drive supporting baseplate 1 and four stabilizer blades 2 descend and support on ground to pack up universal wheel 6 with the help of reset spring 5's elasticity, until first backing plate 18 is located second backing plate 19 under, first backing plate 18 and second backing plate 19 are folded together, at this moment, if place the goods on bearing board 11, under the hindrance of first backing plate 18 and second backing plate 19, universal wheel 6 can't be ejecting.

The goods on the whole logistics tray and the supporting plate 11 are supported by the four support legs 2 and the supporting bottom plate 1, when the moving mechanism is needed, only the rotating handle 17 needs to be screwed reversely, the rotating handle 17 drives the first base plate 18 to be far away from the second base plate 19 through the threaded rod 16 and the threaded connection effect until the first base plate 18 and the second base plate 19 are staggered, and at the moment, due to the fact that the limit of the first base plate 18 and the second base plate 19 is lost, the moving mechanism can be driven to be ejected out of the cavity 3 along the ejection hole under the pressure effect of the supporting plate 11 on the piston 9.

The invention utilizes the deadweight of goods placed on a bearing plate 11, uses hydraulic oil injected into a first hydraulic cavity 8 and a second hydraulic cavity 13 as a force transmission medium by virtue of a first hydraulic cylinder 7, a piston 9, a second hydraulic cylinder 12 and a slide block 14, converts the pressure action exerted on the piston 9 by the bearing plate 11 through a support rod 10 into the supporting action of the slide block 14 on the support leg 2, thereby overcoming the elastic action of a reset spring 5, driving the support leg 2 and a support bottom plate 1 to lift, enabling a universal wheel 6 to be ejected relative to the support leg 2 and to be propped against the ground to support the whole logistics tray, and conveniently moving the logistics tray by virtue of the universal wheel 6, compared with the traditional logistics tray with a hydraulic ejection wheel, the invention can utilize the deadweight of the goods to drive a moving mechanism to eject without manual adjustment, thereby having the advantages of convenient use, time saving and labor saving, and when the moving mechanism is not needed, only need twist and move swing handle 17, can pack up moving mechanism with the help of reset spring 5's elastic force effect, support whole commodity circulation tray with the help of four stabilizer blades 2 and supporting baseplate 1, consequently can move the switching of gesture through convenient completion of stop device.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
