Referring to fig. 1, the sample holder for a stretchable temperature box provided by the present application includes a box body 4, and at least one layer of sample holder (not shown) disposed in the box body 4, wherein a buffer assembly is disposed between the sample holder and the box body 4, a first support arm 11 is disposed on the sample holder, and the buffer assembly connects the first support arm 11 and the box body 4.

The box 4 is a rectangular parallelepiped, and at least one layer of sample holder is provided on the box 4, and in this embodiment, four layers of sample holders are provided. In the embodiment, the distance between the three layers from top to bottom is equal, and the distance is smaller than the distance between the third layer and the fourth layer, that is, the sample rack on the fourth layer can accommodate a higher sample. And the at least one layer of sample frame that this device set up, multilayer sample frame can hold more tested samples promptly, ensures to once only that can be in large batches to accord with and puts the requirement, lets the abundant utilization space of temperature box put big batch sample, promotes the experimental required time by a wide margin to can save not a few test cost. And a handle (not shown) is arranged on the sample holder, so that the sample holder can be conveniently drawn out.

A group of buffer components and a first supporting arm 11 are respectively connected to two sides of each layer of sample rack, so that the sample rack is stressed uniformly when pulled out, and the service cycle is longer. The buffer component can also be used in other existing temperature boxes without the buffer component, the original fixed sample rack is removed, and the buffer component is additionally arranged on the box wall.

The buffer component is arranged between the box body 4 and the sample frame of each layer, the buffer component is provided with a connecting piece, a damper and a first fixed rotor 21, the buffer component is specifically selected according to the use condition of the temperature box, and basically mainly comprises high-low temperature resistant and moisture resistant materials. Because the sample frame is used for shelving the sample of waiting to carry out the temperature test, under the effect of gravity, the sample frame can take place the decline of less distance, and the buffer unit in this embodiment is used for reducing because the sudden decline that gravity arouses makes the sample on the sample frame bump, influences the experiment.

The connecting member is at least partly connected to the housing 4, and in this embodiment the connecting member comprises a first lever arm 32 and a second lever arm 31 connected to the first lever arm 32, the first lever arm 32 being rotatable relative to the second lever arm 31. That is, the first lever arm 32 is provided with a protrusion (not shown), and a corresponding groove (not shown) is provided at a corresponding position of the second lever arm 31, and the groove and the protrusion cooperate to allow the first lever arm 32 and the second lever arm 31 to rotate relatively. The connection mode of the first lever arm 32 and the second lever arm 31 is not limited, and the first lever arm 32 may be provided with a through hole, the second lever arm 31 may be provided with another through hole, and the two through holes may be connected by a link penetrating through the through hole.

As described above, the first lever arm 32 is connected to the box 4, the second lever arm 31 is connected to the first support arm 11, and when the first support arm 11 moves, the second lever arm 31 connected to the first support arm 11 is driven to move, and the first lever arm 32 connected to the second lever arm 31 is driven to move. The section of the first lever arm 32 not connected to the second lever arm 31 is connected to the box 4, and it should be noted that the first lever arm 32 can rotate relative to the box 4, in this embodiment, a groove is provided at the end of the first lever arm 32 connected to the box 4, and a protrusion matching with the groove is provided on the box 4. The length of movement of the first support arm is influenced by the length of the first lever arm and the second lever arm, and the length of the first lever arm and the second lever arm is not limited and can be adjusted adaptively according to actual conditions.

First fixed rotor 21 connects first support arm 11 and box 4, and first fixed rotor can rotate on the box relative to the axis, and first support arm 11 slides around first fixed rotor's periphery, and fixed rotor is prior art, does not give unnecessary details here.

In the present embodiment, the damper is a spring damper provided with two springs, i.e., a first spring 33 and a second spring 34. The first spring 33 has both ends connected to the first lever arm 32 and the first support arm 11, respectively, and the second spring 34 also has both ends connected to the first lever arm 32 and the first support arm 11, respectively. The length of the first spring 33 is longer than that of the second spring 34, the axis of the first spring 33 and the axis of the first support arm 11 form an acute angle, and the axis of the second spring 34 and the axis of the first support arm 11 form an acute angle.

In the present embodiment, the distance between one ends of the first spring 33 and the second spring 34 connected to the first support arm 11 is smaller than the distance between the other ends of the first spring 33 and the second spring 34 on the first lever arm 32. When the axis of the first spring 33 forms an angle with the axis of the first support arm 11, the force of the sample holder suddenly dropping due to gravity is resolved into forces in the horizontal direction and the vertical direction by the first spring 33, and the second spring 34 has the same principle as the first spring 33. The sample frame can realize the slow descending function through the first spring 33 and the second spring 34, and the sample frame is fast before slow without impact when descending, so that the safety of a tested object can be protected, and the time can be saved while the labor is saved. The first spring 33 is longer than the second spring 34, and the first spring 33 is disposed closer to the handle, i.e. the first spring 33 is subjected to a larger force, so that the first spring 33 is subjected to a larger deformation and a larger decomposed force, and in another embodiment, the length of the first spring 33 may be smaller than that of the second spring 34, but the length of the second spring cannot be equal to that of the second spring 34.

When the handle is pulled, the first support arm 11 moves to drive the second lever arm 31 to move, the first lever arm 32 is driven, and the first spring 33 and the second spring 34 on the first lever arm 32 deform, so that the sample rack slowly descends, and the tested sample is stably pulled out. After the sample is placed, the handle is slightly pushed upwards and forwards, the first spring 33 and the second spring 34 are reset, and the sample rack can restore to the initial position in the box. The design needs to solve the holding rate of the sample rack of the temperature box, and meanwhile, the samples are placed more conveniently.

In this embodiment, the temperature box further comprises a second supporting arm 12, and the second supporting arm 12 is disposed below the first supporting arm 11 for supporting the sample holder after the first supporting arm 11 moves. The box 4 is provided with a second stationary rotor 22, and the second stationary rotor 22 connects the box 4 and the second support arm 12. The second support arm 12 is slidable around the periphery of the second stationary rotor 22.

In conclusion, the stretchable temperature box sample rack is simple in structure, the buffer assembly is arranged between the sample rack and the box body, so that the sample rack can realize a slow descending function under the action of the damper, the safety of a tested product is protected, the labor is saved, and the time can be saved. When the supporting arm is driven to move, the sample rack can extend out of the box, and the whole rack surface can be used for conveniently placing the tested sample. And this device is provided with at least one deck sample frame, and more samples that receive can be held to the multilayer sample frame, ensures to once only accord with in large batch and puts the requirement, lets the abundant space of utilizing of temperature box put big batch sample, promotes the experimental required time by a wide margin to can save not a few test cost.
