Detailed Description

The utility model is described in detail below with reference to the attached drawing figures:

in the description of the present utility model, it should be noted that, directions or positional relationships indicated by "up", "down", "left", "right", etc. are directions or positional relationships based on those shown in the drawings, or directions or positional relationships in which the inventive product is conventionally put in use, are merely for convenience of describing the present utility model and simplifying the description, and are not indicative or implying that the apparatus or element to be referred to must have a specific direction, and specific direction configuration and operation, and therefore should not be construed as limiting the present utility model.

As shown in fig. 1-4, a magnetic rack comprises a bottom plate 1, an inclination adjusting device 2, magnetic strips 3 and positioning dents 4, wherein the magnetic strips 3 are arranged on the bottom plate 1 through the inclination adjusting device 2, the magnetic strips 3 are provided with 6 magnetic strips, the arrangement of the 6 magnetic strips 3 can meet the use of 96 pore plates, and when in use, the 96 pore plates are only required to be inserted on the magnetic strips 3. The inclination adjusting device 2 is used for adjusting the distance between two adjacent magnetic strips 3, and the single EP (EP) pipes or eight-row pipes placed on the positioning dents 4 are clamped by adjusting the distance between the magnetic strips 3, so that the use of the EP pipes with different specifications can be met due to the adjustability of the distance. The bottom plate 1 is also provided with a positioning dent 4, and the positioning dent 4 is positioned between the magnetic strips 3 and 3; the positioning dents 4 have the function of stably positioning the bottom of the single EP tube or eight-row tube when it is placed, avoiding sliding, tilting or tipping. The shape of the positioning indentations 4 is set according to the bottom shape of individual EP tubes of different models. The positioning dents 4 are provided with 6 rows of 8, each row is provided with the same shape of the positioning dents 4, and the shapes of the positioning dents 4 are different from row to row.

As shown in fig. 5, the inclination adjusting device 2 comprises a base 21, a rotating clamping shaft 22, a movable piece 23, a fixed shaft 24, a convex strip 25 and a groove 26, wherein 2 bases 21 are opposite and fixedly arranged on the bottom plate 1; a rotary clamping shaft 22 is fixedly arranged at the lower part of the movable piece 23, and the movable piece 23 is arranged on the base 21 through the rotary clamping shaft 22; in order to realize that the movable member 23 can still keep a rotated state after rotation, the rotary clamping shaft 22 is provided with convex strips 25, the convex strips 25 are densely distributed on the surface of the rotary clamping shaft 22 in a circular array by taking the axle center of the rotary clamping shaft 22 as the circle center, the base 21 is provided with grooves 26, and the convex strips 25 and the grooves 26 are matched for use to realize the rotary positioning of the movable member 23, namely, the movable member 23 can keep the original state when no external force exists after the movable member 23 is rotated by the external force. The upper parts of the 2 movable pieces 23 are movably provided with magnetic strips 3 through fixed shafts 24; the left and right ends on the top of the magnetic stripe 3 are movably connected with the fixed shaft 24 (the left and right ends on the top of the magnetic stripe are provided with holes, and the fixed shaft is inserted in the holes), and the movable arrangement of the magnetic stripe 3 can ensure that the movable piece 23 can keep a vertical state regardless of rotating the inclined magnetic stripe 3, so that the contact area with the EP tube is increased. The height of the magnetic strip 3 is smaller than that of the movable piece 23, so as to avoid that the bottom of the movable piece 23 is propped against the bottom plate 1 to keep a vertical state due to the fact that the bottom of the magnetic strip 3 is too high after the movable piece 23 is inclined.

While particular embodiments of the present utility model have been illustrated and described in detail, it should be noted that various changes and modifications could be made to the above-described embodiments without departing from the spirit of the utility model and the scope of the appended claims.
