Description

Technical Field

[0001] The utility model relates to the technical field of clamping instruments, in particular to a clamping device for a sample rack. Background Art

[0002] With the development of society, microorganisms such as biological enzymes are increasingly used in people's lives, and people's requirements for biological tests are becoming more and more stringent.

[0003] After observing and culturing microorganisms such as biological enzymes, they need to be placed in a sample rack for placement and reaction. This process is usually carried out using reagent tubes or culture dishes. To prevent contamination, a clamping device is needed to take and place the culture dishes in the sample rack. However, most existing clamping devices are ordinary tube clamps or tweezers. Their length and clamping method are not suitable for taking and placing culture dishes in the sample rack. Because the clamping is not firm enough, they are easy to fall during the clamping process. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the above technical difficulties and provide a clamping device for a sample rack, which has a suitable length and can easily penetrate into the sample rack to prevent pollution to the environment inside the sample rack. At the same time, the clamping rod clamps the culture dish in a parallel manner to prevent the culture dish from slipping.

[0005] In order to solve the above technical problems, the technical solutions provided by the present invention are as follows:

[0006] A clamping device for a sample rack, comprising:

[0007] The main body of the scissor-type clamping device includes a pair of connecting rods arranged in an X-shape and rotatably connected at the intersection, and the portion of the connecting rod located on one side of the rotatable connection forms a handle portion;

[0008] The clamping device chuck includes a clamping rod and a limiting structure; the clamping rod is provided with a pair and one end is hinged to the non-handle end of the two connecting rods respectively, the two clamping rods are connected by a limiting structure, and clamping grooves are formed correspondingly on the clamping surface. The scissor-type clamping device body drives the two clamping rods to move relative to each other in parallel or move toward and away from each other.

[0009] As an improvement, the limiting structure includes a limiting rod and a limiting rod sleeve; the limiting rod sleeve is formed near the hinge end of the clamping rod, and the limiting rod passes through both limiting rod sleeves. After one end is fixedly connected to one limiting rod sleeve, the remaining portion is movably connected to the other limiting rod sleeve, which is used to limit the two clamping rods to enable parallel relative movement or movement toward and away from each other.

[0010] As an improvement, a plurality of clamping notches are evenly arranged along the axial direction on the clamping rod, and the sizes are different, so that the two clamping rods can stably clamp culture dishes of different sizes and test tubes.

[0011] The advantages of this utility model compared with the prior art are:

[0012] 1. The utility model itself has a suitable length, which can easily penetrate into the sample rack and clamp the culture dish on the sample rack, preventing the hand from entering the sample rack and causing pollution to the internal environment. It is convenient and practical.

[0013] 2. The clamping rod of the utility model clamps the culture dish in a parallel manner, and the clamping surface is provided with a clamping notch, which effectively prevents the culture dish from slipping and is safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] A clamping device for a sample rack, comprising:

[0022] The main body of the scissor-type clamping device includes a pair of connecting rods 1 arranged in an X-shape and rotatably connected at the intersection. The part of the connecting rod 1 located on one side of the rotation connection forms a handle part 2, and the handle part 2 is a closed loop structure. Figure 3 As shown;

[0023] The clamping device chuck includes a pair of clamping rods 3, one end of which is hinged to the non-handle end of each connecting rod 1, and a clamping notch 6 is formed on the clamping surface. The limiting structure includes a limiting rod 4 and a limiting rod sleeve 5. The limiting rod sleeve 5 is formed near the hinge end of the clamping rod 3. The limiting rod 4 passes through both limiting rod sleeves 5. After one end is fixedly connected to one limiting rod sleeve 5, the remaining portion is movably connected to the other limiting rod sleeve 5.

[0024] As a preferred embodiment, the limiting rod 4 is a square rod, which has higher strength and is not easily deformed.

[0025] As a preferred embodiment, a pair of the limiting structures are provided along the axial direction of the clamping rod 3, so that the two clamping rods 3 can be kept in a parallel state more stably.

[0026] As a preferred embodiment, a plurality of clamping notches 6 are evenly arranged along the axial direction on the clamping rod 3 , and the sizes of the clamping notches are different.

[0027] In the specific implementation of this embodiment:

[0028] When using the sample holder to clamp the culture dish with the clamping device, hold the handle part 2 and extend the clamping device into the sample holder. Operate the handle part 2 to expand the scissor-type clamping device body and drive the clamping device chuck to separate to both sides. Extend the clamping device chuck toward the culture dish to be taken out, and make the two clamping rods 3 on both sides of the culture dish. Close the scissor-type clamping device body, retract the clamping device chuck, and the arc-shaped clamping surface of the clamping notch 6 contacts the side wall of the culture dish. Under the action of friction, the culture dish is taken out.

[0029] When using the sample rack clamping device to clamp the reagent tube, as shown in the above steps, the clamping device chuck is extended toward the reagent tube to be taken, and the scissor-type clamping device body is closed to retract the clamping device chuck. The semicircular notch of the thin-sheet head of the clamping slot 6 is engaged with the tube mouth of the reagent tube, and the tube is supported under the tube cap of the reagent tube to take out the reagent tube.

[0030] When not in use, the sample rack clamping device can be hung on a wall via the handle 2 .

[0031] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
