The multi-position rotary barcode scanning device 30 of the present invention is provided with a sample tube limiting mechanism 340 to limit the position of the sample tube 90 to avoid the position of the sample tube 90 when it rotates with the first rotating seat 311 or the second rotating seat 312 move. Specifically, the sample tube limiting mechanism 340 is used to limit the position of the sample tube 91 of the first specification. When the sample tube 91 of the first specification is placed on the first rotating seat 311 , the sample tube limiting mechanism 340 will limit the position of the sample tube 91 of the first specification. The tube 91 is limited to prevent the displacement of the sample tube 91 of the first specification and improve the efficiency of code scanning.

If the diameter of the first limit bars 342 is greater than 5 mm, on the one hand, the cost is high, and on the other hand, the distance between the adjacent first limit bars 342 will be reduced. Reduce the scanning range and reduce the scanning accuracy.

In a specific example, an end of the first limiting bar 342 away from the limiting fixing seat 341 is bent to form a first bending portion, and the end portion extends outward.

The arrangement of the first bending part can play the role of holding the sample tube 91 of the first specification or the sample tube 92 of the second specification, because the first bending part tends to be in the limiting space, that is, a plurality of first bending parts The distance formed by the parts is smaller than the radial dimension of the limiting space, so that the first-size sample tube 91 or the second-size sample tube 92 can be clamped, even if the outer diameter of the first-size sample tube 91 or the second-size sample tube 92 If it is smaller than the radial dimension of the limiting space, the limiting and fixing effect of the sample tube 91 of the first specification or the sample tube 92 of the second specification can also be achieved through the clamping action of the plurality of first bending parts.

The multi-position rotary barcode scanning device 30 of the present invention is provided with a plurality of second limit bars 343, and the plurality of second limit bars 343 and the first limit bars 342 together form a sample tube 91 or a second limit bar for the first specification sample tube 91 or the second limit bar 342. The limit space accommodated by the standard sample tube 92, the length of the second limit bar 343 is longer than the length of the first limit bar 342, so the setting can be applied to the placement of the first standard sample tube 91 or the second standard sample tube 92 of various lengths Entering the limited space, it is convenient to take and hold, and has wide adaptability.

In a specific example, the second limiting strip 343 has elasticity. Preferably, the second limiting bar 343 may be an elastic wire-like structure made of spring steel wire, spring steel bar, or other metal materials. The second limit bar 343 is elastically arranged to realize its own bending and reset. When the first specification sample tube 91 or the second specification sample tube 92 needs to be inserted, the second limit bar 343 can be manually pulled outward. Move to facilitate putting in the first-size sample tube 91 or the second-size sample tube 92, or when the outer diameter of the first-size sample tube 91 or the second-size sample tube 92 is slightly larger than the radial dimension of the limiting space, It can be adapted to the sample tube 91 of the first specification or the sample tube 92 of the second specification through the elastic deformation of the second limiting strip 343 , without replacing the limiting mechanism, which increases the adaptation range.

Further, the second limiting bar 343 is a filament-like structure, and the diameter of the second limiting bar 343 is 1 mm-5 mm. For example, the diameter of the second limiting strip 343 is 1 mm, 2 mm, 3 mm, 4 mm, 5 mm or other non-integer values. The diameter of the second limit bar 343 is not easy to be too small. If the diameter of the second limit bar 343 is less than 1 mm, the strength is low, and the second standard sample tube 92 or the second standard sample tube 92 cannot be well limited. fixed. The diameter of the second limit bars 343 is not easy to be too large. If the diameter of the second limit bars 343 is greater than 5 mm, on the one hand, the cost is high, and on the other hand, the distance between the adjacent second limit bars 343 will be reduced. Reduce the scanning range and reduce the scanning accuracy.

In a specific example, one end of the second limiting bar 343 away from the limiting fixing seat 341 is bent to form a second bending portion, and the end portion extends outward. In the multi-station rotary barcode scanning device 30 of the present invention, one end of the second limit bar 343 away from the limit fixing base 341 is bent and the end extends outward, so that the end of each second limit bar 343 faces outward. By extending, the opening becomes larger, which is convenient for placing the sample tube 91 of the first specification or the sample tube 92 of the second specification into the limiting space.

In a specific example, one end of the second limiting bar 343 away from the limiting fixing seat 341 is bent toward the limiting space to form the second bending portion.

The arrangement of the second bending portion can play the role of holding the sample tube 91 of the first specification or the sample tube 92 of the second specification, because the second bending portion tends to be in the limiting space, that is, a plurality of second bending portions The distance formed by the parts is smaller than the radial dimension of the limiting space, so that the first-size sample tube 91 or the second-size sample tube 92 can be clamped, even if the outer diameter of the first-size sample tube 91 or the second-size sample tube 92 If it is smaller than the radial dimension of the limiting space, the limiting and fixing effect of the sample tube 91 of the first standard or the sample tube 92 of the second standard can also be achieved through the clamping action of the plurality of second bending portions.
