[0009] In the above-mentioned improved reagent loading device, the fixed claw includes a clamping end and a connecting end, the outer end of the movable claw is directly opposite to the clamping end of the fixed claw, the connecting end is in contact with the main body surface and the two are connected by a fastener.

[0010] In the above-mentioned improved reagent loading device, the main body has several penetrating positioning holes 1 along its length direction, the connecting end of the above-mentioned fixing claw has at least two positioning holes 2, and the fasteners are inserted through the positioning holes 1 and 2 and fix the connecting end to the main body.

[0011] The improved reagent loading device further comprises a rod-shaped connecting rod three, one end of which is fixedly connected to the upper end of the connecting rod one, and the other end of which is fixedly connected to the inner end of the body.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0026] like Figure 1 and Figure 2 and Figure 3 As shown, the improved reagent loading device includes a frame 1, and also includes a connecting rod 2, a connecting rod 3, a cylinder 4 and a clamping assembly. The lower end of the connecting rod 2 is hinged at the middle of the frame 1, and the frame 1 has a transversely arranged guide rail 5. The inner end of the connecting rod 2 3 is connected to the guide rail 5, and the outer end of the connecting rod 2 3 is hinged to the upper end of the connecting rod 2. The cylinder body of the cylinder 4 is hinged on the frame 1, the piston rod of the cylinder 4 is hinged to the middle of the connecting rod 2, and the clamping assembly is connected to the upper end of the connecting rod 2.

[0027] During the extension and retraction process of the piston rod of the cylinder 1 4 , the connecting rod 1 2 and the connecting rod 2 3 swing accordingly, and the clamping assembly on the connecting rod 1 2 makes a corresponding trajectory movement along with the above-mentioned swing.

[0028] That is, the clamping assembly can be changed from a non-clamping state to a clamping state.

[0029] Specifically, in the non-clamping state, the clamping assembly is away from the reagent tube. When the clamping assembly enters the state after swinging, it can stably clamp the reagent tube at the corresponding work station. After switching between the above two states, the reagent tube is finally clamped and placed in the corresponding work station.

[0030] The guide rail 5 is in the shape of an elongated strip, the inner side of the guide rail 5 is in surface contact with the frame 1 and the two are fixedly connected, the outer side of the guide rail 5 has a concave guide groove 5a along its length direction, the inner end of the connecting rod 2 3 is movably connected with a roller 6, and the roller 6 is embedded in the guide groove 5a.

[0031] Such a structure can cause rolling friction between the inner end of the connecting rod 2 3 and the guide rail 5 , which effectively reduces the friction resistance and ensures that the connecting rod 2 3 can translate smoothly along the guide rail 5 .

[0032] The clamping assembly includes a body 7, a cylinder 8, a fixed claw 9 and a movable claw 10. The body 7 is in the shape of a long rod. The inner end of the body 7 is fixedly connected to the upper end of the connecting rod 2, the fixed claw 9 is fixedly connected to the outer end of the body 7, the inner end of the cylinder 8 is hinged on the body 7, the middle part of the movable claw 10 is hinged to the outer end of the body 7, the piston rod of the cylinder 8 is hinged to the inner end of the movable claw 10, and the outer end of the movable claw 10 is opposite to the fixed claw 9. In the initial state, the outer end of the movable claw 10 is away from the fixed claw 9. When the cylinder 8 is actuated, the movable claw 10 can swing around its hinge and make the outer end of the movable claw 10 close to the fixed claw 9.

[0033] In the initial state, the movable claw 10 is away from the fixed claw 9. When the cylinder 2 8 drives the movable claw 10 to swing, the movable claw 10 and the fixed claw 9 can be opened and closed, so as to stably grasp the corresponding reagent tube.

[0034] The fixed claw 9 includes a clamping end 9a and a connecting end 9b. The outer end of the movable claw 10 is directly opposite to the clamping end 9a of the fixed claw 9. The connecting end 9b is in surface contact with the body 7 and the two are connected by a fastener.

[0035] The main body 7 has a plurality of through positioning holes 7a along its length direction, and the connecting end 9b of the fixing claw 9 has at least two positioning holes 9b1, and fasteners are inserted through the positioning holes 7a and 9b1 to fix the connecting end 9b to the main body 7.

[0036] The connection end of the fixing claw 9 is provided with two positioning holes 9b1, and each positioning hole 9b1 is provided with a fastener, and the body 7 and the fixing claw 9 can be stably fixed together under the action of the fastener.

[0037] It also includes a rod-shaped connecting rod three 11, one end of which is fixedly connected to the upper end of the connecting rod 1 2, and the other end of the connecting rod three 11 is fixedly connected to the inner end of the body 7.

[0038] Under the action of connecting rod three 11, not only can the clamping assembly be connected to connecting rod one 2, but also the clamping assembly can be kept as far away from connecting rod one 2 as possible to avoid obstruction of the clamping assembly during the swinging process of connecting rod one 2.

[0039] One end of the connecting rod 3 11 is provided with a disc-shaped flange 11a, and the flange 11a is fixedly connected to the upper end of the connecting rod 1 2 via a fastener.

[0040] Under the action of the flange 11a, the connecting rod 3 11 and the connecting rod 1 2 can be stably and fixedly connected.

[0041] The inner end of the body 7 has a concave deformation notch 7b, and the inner end of the deformation notch 7b has a connecting hole 7b1 matching the connecting rod three 11, and the other end of the connecting rod three 11 is embedded in the connecting hole 7b1 and the two are tightly fitted and connected.

[0042] A fastener is connected to the end of the deformation recess 7b.

[0043] The fastener is threadedly connected to the deformation notch 7b of the body 7. After the fastener is tightened, the inner diameter of the connecting hole 7b1 can be reduced, thereby ensuring that the body 7 and the connecting rod 3 11 are stably connected.

[0044] The body 7 has a protruding connection section 7c at one end of the inner deformation recess 7b, and the cylinder body of the cylinder 2 8 is hinged at the connection section 7c.

[0045] The connecting section 7c extends out of the main body 7, and a sufficient position is provided through the connecting section 7c for the cylinder 2 8 to be connected.

[0046] In the improved reagent loading device, when the cylinder 1 drives the connecting rod 1 and the connecting rod 2 to swing, the clamping assembly can swing along with it, and the clamping assembly itself can be used to clamp the reagent tube. It can be seen that the device can make the clamping assembly switch back and forth between the initial position and the moved position. After the clamping assembly clamps the reagent tube, the loading and transportation of the reagent tube is finally realized, and its stability is relatively high.

[0047] At the same time, the moving stroke of the device is simple and the structure of the entire device is not complicated. Therefore, its cost is relatively low and it is very suitable for loading and clamping reagent tubes.

[0048] In addition, the clamping assembly is compactly connected to the tube body, so the entire device has a compact structure and high practical value.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention.
