[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0038] Please see Figure 1-6 This utility model discloses a sample carrying device for a programmable cooling instrument, characterized in that it includes a carrying component 1 and an adjusting component 2 disposed in a cooling chamber;

[0039] The supporting component 1 is used to place the sample container;

[0040] The adjusting component 2 includes an adjusting assembly 21 and a transmission assembly 22 connected to the bearing component 1;

[0041] The transmission component 22 is installed inside the instrument body 01 and connected to the adjustment component 21. The transmission component 22 drives the bearing component 1 to move vertically up and down through the adjustment component 21.

[0042] In practice, when it is necessary to remove the sample container, the staff opens the instrument body 01 and drives the transmission component 22 to work, so that the adjustment component 21 drives the bearing component 1 to rise vertically, and then the bearing component 1 drives the sample container away from the cooling chamber. After the sample container is removed, the transmission component 22 drives the bearing component 1 to fall again through the adjustment component 21, so that it can re-enter the cooling chamber.

[0043] In this invention, through the cooperation between the supporting component 1 and the adjusting component 2, the transmission component 22 drives the supporting component 1 to rise and fall through the adjusting component 21. Thus, when it is necessary to remove the sample container, the supporting component 1 is raised so that it temporarily leaves the cooling chamber, eliminating the need for staff to put their hands into the cooling chamber, making it convenient for staff to pick up and put down samples.

[0044] In one embodiment, the instrument body 01 has an inner cavity 011, and the transmission component 22 is disposed in the inner cavity 011;

[0045] The adjustment assembly 21 includes four adjustment brackets equidistantly distributed within the cooling chamber;

[0046] The adjustment frame includes an adjustment cylinder 211 that is vertically rotatably disposed in the cooling chamber. The bottom end of the adjustment cylinder 211 extends into the inner cavity 011 and is connected to the transmission assembly 22. The cylinder has a transmission thread inside. The transmission assembly 22 is connected to each adjustment cylinder 211 to drive each adjustment cylinder 211 to rotate together.

[0047] It also includes adjusting rods 212 that are vertically sleeved in the adjusting cylinder 211 and threadedly connected thereto. Each adjusting rod 212 is connected to the bearing component 1 to form a linkage lifting structure, so as to drive the bearing component 1 to lift.

[0048] The adjusting cylinder 211 is also vertically fitted with a constraint rod 213. The top end of the constraint rod 213 is connected to the bottom of the adjusting rod 212, and its bottom end forms a vertical sliding fit with the instrument body 01. The constraint rod 213 is used to prevent the adjusting rod 212 from rotating together with the adjusting cylinder 211.

[0049] With this design, when the sample container needs to be removed, the transmission component 22 drives each adjusting cylinder 211 to rotate together, thereby causing each adjusting rod 212 to rise together, which in turn drives the bearing component 1 to move upward. When the adjusting cylinder 211 rotates, the constraint rod 213 constrains the adjusting rod 212 to rotate together with the adjusting cylinder 211.

[0050] In one embodiment, the transmission assembly 22 includes a synchronization member 221 and a drive member 222;

[0051] The synchronization component 221 includes a plurality of synchronization wheels 2211 respectively sleeved on the bottom end of each adjusting cylinder 211, and each synchronization wheel 2211 is equidistantly arranged in the inner cavity 011;

[0052] It also includes a synchronous belt 2212 disposed between two adjacent synchronous pulleys 2211. The driving component 222 is connected to the corresponding synchronous pulley 2211 to form a multi-cylinder synchronous drive structure. When one of the adjusting cylinders 211 rotates, each synchronous pulley 2211 and the synchronous belt 2212 cooperate to drive each adjusting cylinder 211 to rotate together.

[0053] With this design, when it is necessary to drive each adjusting cylinder 211 to rotate together, the driving component 222 drives the corresponding adjusting cylinder 211 to rotate, the synchronous wheel 2211 on the cylinder rotates together, and drives another synchronous wheel 2211 connected to it to rotate through the corresponding synchronous belt 2212, and in turn drives each adjusting cylinder 211 to rotate together through the corresponding synchronous belt 2212 connected to it.

[0054] In one embodiment, the driving member 222 includes a power unit 2221 disposed in the inner cavity 011 and a meshing transmission mechanism:

[0055] The meshing transmission mechanism consists of a first gear 2222 fixed on the corresponding adjusting cylinder 211, and a second gear 2223 coaxially connected to the output end of the power unit 2221 and meshing with the first gear 2222.

[0056] With this design, when the adjusting cylinder 211 needs to rotate, the power unit 2221 drives the second gear 2223 to rotate, which in turn drives the first gear 2222 to rotate, thereby causing the corresponding adjusting cylinder 211 to rotate. Then, through the coordination of the synchronization component 221, all adjusting cylinders 211 are driven to rotate together.

[0057] In one embodiment, the supporting component 1 includes a support frame 11 connected to each adjusting rod 212, the support frame 11 being used to support sample containers;

[0058] It also includes a constraint frame 12 disposed above the support frame 11 and connected to each adjustment rod 212, and the constraint frame 12 has a plurality of positioning holes 121 for placing sample containers.

[0059] With this design, when it is necessary to place sample containers, the staff will pass each sample container through the corresponding positioning hole 121 and make its bottom contact with the support frame 11, so that the support frame 11 supports each sample container, while the constraint frame 12 prevents each sample container from tipping over through each positioning hole 121.

[0060] In one embodiment, the constraint frame 12 is further provided with a clamping component 3, which includes a plurality of clamping assemblies that correspond one-to-one with each positioning hole 121;

[0061] The clamping assembly includes two grippers 31 that are slidably disposed within the constraint frame 12 and located on both sides of the corresponding positioning hole 121. The grippers 31 are used to clamp the sample container.

[0062] It also includes an elastic unit 32 disposed between each gripper 31 and the constraint frame 12, the elastic unit 32 being used to apply a thrust to the corresponding gripper 31 in the direction of approaching the axis of the corresponding positioning hole 121.

[0063] With this design, when the sample container is placed into the positioning hole 121, the sample container contacts the corresponding two grippers 31 and applies a pushing force to them in a direction away from the axis of the positioning hole 121 until the bottom of the sample container contacts the support frame 11. At this time, the elastic unit 32 is compressed and applies a clamping force to the corresponding grippers 31 in a direction close to the axis of the positioning hole 121 to clamp the sample container and prevent the sample container from moving accidentally.

[0064] It should be noted that the top of the gripper 31 is provided with a guide slope. When the sample container comes into contact with the gripper 31, the guide slope guides the sample container to move towards the center of the positioning hole 121 and can better enable the sample container to push the gripper 31.

[0065] It should be noted that the gripping surface of the gripper 31 is lined with an inner lining (such as rubber), which reduces the damage to the sample container by the gripper 31 without affecting the gripping force.

[0066] Preferably, the elastic unit 32 can be a spring from the prior art.

[0067] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0068] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0069] Additionally, "multiple" refers to two or more.

[0070] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
