The utility model discloses a specific technical scheme be: the utility model provides an underground water sampling support, includes support body and landing leg, the key is: the support body is welded with an inserting cylinder, the supporting legs are detachably matched with the inserting cylinder in an inserting manner, a limiting block is arranged in the inserting cylinder, and the inserting cylinder is in a conical shape with a thin upper part and a thick lower part; the top end of the landing leg is provided with a limiting groove matched with the limiting block, an annular clamp spring groove is formed below the limiting groove, a clamp spring is sleeved in the clamp spring groove, and the diameter of the clamp spring is larger than that of the landing leg.

The bracket body comprises an upper-layer ring, a lower-layer ring and an upper-layer ring and a lower-layer ring; the connecting rod, upper ring diameter be greater than lower floor's ring.

The landing leg set up at least, landing leg bottom fixedly connected with backup pad.

The end of the plug cylinder, which is matched with the supporting leg, is in a cone shape with a thin upper part and a thick lower part.

The utility model has the advantages that: the supporting legs can be detached respectively, the installation and the detachment are convenient, the supporting legs are directly inserted, and the limiting blocks can play a role in limiting the rotation of the supporting legs; and the landing leg card is made landing leg and this body coupling of support form a whole with the grafting section of thick bamboo with the jump ring, is difficult to drop.

FIG. 3 is a cross-sectional view of the socket of the present invention;

FIG. 4 is a schematic view of the top structure of the landing leg of the present invention;

in the attached drawing, the support comprises a support body 1, a support body 1-1, an upper layer circular ring 1-2, a lower layer circular ring 1-3, a connecting rod 2, a splicing barrel 2-1, a limiting block 3, a supporting leg 3-1, a limiting groove 3-2, a clamp spring groove 4, a clamp spring 5 and a supporting plate.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and specific embodiments:

the utility model provides an underground water sampling support, includes support body 1 and landing leg 3, the key is: the support comprises a support body 1 and is characterized in that an inserting cylinder 2 is welded on the support body 1, a supporting leg 3 is detachably matched with the inserting cylinder 2 in an inserting manner, a limiting block 2-1 is arranged inside the inserting cylinder 2, and the inserting cylinder 2 is in a conical shape with a thin upper part and a thick lower part; the top end of the landing leg 3 is provided with a limiting groove 3-1 matched with the limiting block 2-1, an annular clamp spring groove 3-2 is formed below the limiting groove 3-1, a clamp spring 4 is sleeved in the clamp spring groove 3-2, and the diameter of the clamp spring 4 is larger than that of the landing leg 3.

As shown in fig. 1, 3 and 4, the bracket body 1 is welded with the insertion cylinder 2, and the support legs 3 are directly inserted into the insertion cylinder 2 when in use, so that the assembly and disassembly are convenient, and the whole bracket is simple and convenient to transport and store due to the disassembly; the plug-in cylinder 2 is a cone with a thin upper part and a thick lower part, so that the supporting leg 3 with the clamp spring 4 can conveniently enter the plug-in cylinder, and the clamp spring 4 is elastic and is extruded into the plug-in cylinder 2. Extrusion force can be generated with the inner wall of the inserting cylinder 2, so that the supporting legs 3 are limited and cannot slide out of the inserting cylinder 2; the inner wall of the inserting cylinder 2 is provided with a limiting block 2-1, the top end of the supporting leg 3 is provided with a limiting groove 3-1 for the limiting block 2-1 to slide into, and the supporting leg 3 can be limited not to rotate after the limiting block 2-1 enters the limiting groove 3-1.

As shown in fig. 2, the stent body 1 comprises an upper layer ring 1-1, a lower layer ring 1-2, and an upper layer ring 1-1 and a lower layer ring 1-2; the diameter of the upper layer ring 1-1 is larger than that of the lower layer ring 1-2.

The upper-layer circular ring 1-1 and the lower-layer circular ring 1-2 are suitable for sampling devices with different sizes, and the double-layer circular ring is stable in structure, plays a role in protecting the devices placed in the double-layer circular ring from side turning and is stable in center of gravity.

As shown in figure 1, at least 3 support legs 3 are arranged, and a support plate 5 is fixedly connected to the bottom ends of the support legs 3.

3 landing legs 3 can make structure and focus more stable, and the area of contact of the 5 increases of backup pad and ground of 3 bottoms of landing legs makes whole supports place steadily.

As shown in fig. 3, the end of the plug cylinder 2, which is engaged with the leg 3, is tapered with a thin upper part and a thick lower part.

The conical opening makes it easier for the leg 3 and the clamping spring 4 to enter the plug-in cylinder 2.
