Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

The first embodiment is as follows:

fig. 1-3 show a single-row magnetic rod sleeve of the present invention, which comprises a strip-shaped base plate 1; a row of pipe sleeves 3 which are uniformly arranged at intervals are vertically arranged on the substrate 1; one end of the pipe sleeve 3 connected with the substrate 1 is open, and the other end is closed; the closed end of the pipe sleeve 3 is of a hemispherical structure; the utility model has the advantages that the closed end of the pipe sleeve 3 is of a hemispherical structure, so that the adsorbed magnetic beads are more uniform, and the phenomenon of liquid hanging can be avoided; simultaneously, the distance of bar magnet distance blind end bottom is littleer than the distance of bar magnet distance blind end bottom in the V-arrangement structure among the semi-spherical structure, and then reaches better magnetism and inhale the effect.

Furthermore, the pipe sleeve 3 is conical, and the diameter of the opening end of the pipe sleeve is larger than that of the closed end of the pipe sleeve, so that the pipe sleeve can be conveniently inserted into a deep hole plate.

Furthermore, the two sides of the bottom of the base plate 1 are provided with the first reinforcing ribs 2, so that the strength of the base plate 1 in the horizontal direction can be improved, and the closed ends of the pipe sleeves 3 are positioned on the same horizontal plane.

Furthermore, eight second reinforcing ribs 5 which are uniformly distributed circumferentially are further arranged at the bottom of the base plate 1 around each pipe sleeve 3, so that the verticality of the pipe sleeves 3 and the base plate 1 can be improved.

Further, the number of the pipe sleeves 3 is one of 6, 8 and 12, and can be selected according to the type of the deep hole plate.

Further, one end of the base plate 1 is provided with a handle 4, so that the base plate is convenient to take.

Further, base plate 1, pipe box 3, first strengthening rib 2, second strengthening rib 5, the integrative injection moulding of handle 4, not only be convenient for make, and can guarantee that the blind end of pipe box 3 is located same horizontal plane, the greatly reduced error.

Example two:

as shown in fig. 4, the difference from the first embodiment is that: the base plate 1 and the pipe sleeve 3 are in detachable design; the base plate 1 is provided with a through hole for mounting the pipe sleeve 3; the hole wall of the through hole is of an inwards concave structure; the outer surface of the upper part of the pipe sleeve 3 is provided with a convex structure 6 corresponding to the concave structure; the pipe sleeve 3 can be clamped on the base plate 1 through the matching of the concave structure and the convex structure 6, so that the damaged single sleeve pipe can be conveniently replaced, and the waste phenomenon caused by the fact that the whole magnetic rod sleeve needs to be replaced due to the damage of the single sleeve pipe is avoided; of course, the base plate 1 and the sleeve may be screwed together.

Further, the concave structure and the convex structure 6 are both arc-shaped, so that the installation and the disassembly are convenient.
