[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a sample storage device for chemical engineering.

[0026] The utility model provides Figure 1-3 A sample storage device for chemical engineering shown in the figure comprises a storage box 1 and a box cover 2 wrapped around the outside of the storage box 1, a switch lock 3 is fixedly penetrated on the top of the storage box 1 and the box cover 2, a cross bar 4 is rotatably penetrated on the lower end of the interior of the storage box 1, the box cover 2 is fixedly sleeved on the two ends of the outer side of the cross bar 4, a first screw rod 5 and a second screw rod 6 are rotatably provided on the two ends of the inner wall of the storage box 1, respectively, the thread pitch of the rod wall of the first screw rod 5 is smaller than the thread pitch of the rod wall of the second screw rod 6, the rod walls of the first screw rod 5 and the second screw rod 6 are threadedly sleeved with sliders 7, the tops of the two sliders 7 are fixedly provided with storage boxes 8, the outer walls of the two storage boxes 8 are in contact with the inner wall of the storage box 1, the inner wall of the storage box 8 is fixedly provided with a partition frame 16, and the side walls of the partition frame 16 and the inner wall of the storage box 8 are fixedly provided with a squeeze sponge 17.

[0027] When storing chemical samples, the two storage boxes 8 can be pushed out of the storage box 1 and arranged in a staggered manner by driving the first screw rod 5 and the second screw rod 6. At this time, the chemical samples can be placed in the storage box 8. The storage box 8 is divided into multiple storage spaces by the setting of the partition frame 16, and the sample can is clamped with a stabilizer under the support of two adjacent squeezing sponges 17. The box cover 2 is connected to the storage box 1 through the cross bar 4. When the box cover 2 and the storage box 1 are closed and connected, the multi-layer storage box 8 can be placed in the storage box 1. At the same time, under the connection of the switch lock 3, the storage box 1 and the box cover 2 are connected, thereby completing the stable packaging and storage of most chemical samples.

[0028] In order to enable the multi-layer storage box 8 to be moved in and out synchronously and arranged in a staggered manner, as shown in FIG. Figure 1As shown, the rod walls of the first screw rod 5 and the second screw rod 6 are jointly provided with a synchronous drive mechanism, and the synchronous drive mechanism includes a worm 9. The rod walls of the first screw rod 5 and the second screw rod 6 are fixedly sleeved with a worm wheel 10. The worm 9 is rotatably connected to the bottom of the inner wall of the storage box 1 and is arranged in cooperation with the two worm wheels 10.

[0029] When the box cover 2 and the storage box 1 are opened, the worm 9 starts to rotate. At this time, the meshing of the worm 9 and the two worm wheels 10 can make the first screw 5 and the second screw 6 rotate at the same time. Since the pitch of the first screw 5 is different from the pitch of the second screw 6, the two sliders 7 can move different distances when rotating the same number of circles. At this time, the multi-layer storage box 8 is movable and staggered, which is convenient for direct placement and convenient retrieval of the sample jars, thereby improving the convenience of use of the storage device.

[0030] In order to be able to drive the worm 9 to rotate when the box cover 2 is separated from the storage box 1, Figure 1 As shown, a fixing block 11 is fixedly provided at the bottom of the inner wall of the storage box 1, a transmission rod 12 is rotatably penetrated inside the fixing block 11, first bevel gears 13 are fixedly provided at both ends of the transmission rod 12, and second bevel gears 14 and third bevel gears 15 are fixedly provided on the rod walls of the cross bar 4 and the worm 9, respectively, and the second bevel gears 14 and the third bevel gears 15 are respectively meshed with the two first bevel gears 13.

[0031] When the box cover 2 is separated from the storage box 1, the box cover 2 drives the cross bar 4 to rotate. At this time, the second bevel gear 14 is meshed with the first bevel gear 13 on the right side, so that the cross bar 4 and the transmission rod 12 rotate synchronously, and the first bevel gear 13 on the left side of the transmission rod 12 is meshed with the third bevel gear 15, so that the transmission rod 12 and the worm 9 rotate synchronously. Therefore, when the box cover 2 is opened, the cross bar 4, the transmission rod 12 and the worm 9 rotate synchronously, which is convenient for driving multiple storage boxes 8 to move horizontally and be staggered, so as to facilitate the placement and retrieval of samples.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
