Description

Technical Field

[0001] The utility model relates to the field of sample storage devices, in particular to a temporary sample storage cabinet. Background Art

[0002] The temporary sample storage cabinet is a cabinet used to store human or animal samples for a short period of time. It is widely used in outdoor sampling. It is also used in hospitals when the sampling area is far away from the inspection area.

[0003] The Chinese patent publication number CN217117864U discloses a sample storage cabinet, which includes a sample storage cabinet body, wherein a plurality of sample placement slots are equidistantly arranged inside the sample storage cabinet body, and the sample placement slots are arranged in a ring shape. The plurality of sample placement slots are rotatably arranged in the sample storage cabinet body through a rotating shaft, and synchronous rotation is achieved through a transmission mechanism and a driving motor.

[0004] The designer of this patent believes that the sample storage cabinet body is deep, and it is inconvenient to take the samples inside. Therefore, it is configured as a rotatable sample placement slot. The sample placement slot is made of transparent plastic material, and the sample can be identified by rotating the sample placement slot and observing its outer wall.

[0005] Since the sample placement slot is built into the sample storage cabinet body, the sampler can only see the outer wall of the sample placement slot by looking directly at the sample placement slot. The rotation of the sample placement slot can only enable the sampler to observe a circle of samples on the periphery of the sample placement slot. The sample storage cabinet body will cause interference, resulting in the sampler being unable to see the samples radially close to the center of the sample placement slot. Therefore, the problem of inconvenience in sampling still exists. Utility Model Content

[0006] The utility model aims at the disadvantage that the existing sample storage cabinet adopts a rotating sample placement slot, which still has the disadvantage of inconvenient sampling, and provides a sample temporary storage cabinet which is convenient for sampling.

[0007] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0008] A temporary sample storage cabinet comprises a cabinet body and a sample placement box which rotates horizontally in the cabinet body, a guide structure which allows the sample placement box to completely enter the cabinet body or partially extend out of the cabinet body is arranged between the cabinet body and the sample placement box, and the guide structure comprises a mounting shaft which vertically passes through the center of the sample placement box and is rotatably matched with the sample placement box, and a guide groove which is arranged on the inner wall of the cabinet body and allows the upper and lower end surfaces of the mounting shaft to be partially inserted and reciprocate along the opening direction of the cabinet body.

[0009] By adopting the above scheme, the sample placement box is rotatably matched with the installation shaft, and the installation shaft guide is set in the guide groove. The sampling personnel can drive the sample placement box to completely enter the cabinet or partially extend it out of the cabinet by moving the installation shaft. After the sample placement box partially extends out of the cabinet, its extended part is completely exposed to the field of vision of the sampling personnel. The sampling personnel can fully identify the sample in the sample placement box by rotating the sample placement box, and sampling and placement are more convenient.

[0010] Preferably, an operating component for facilitating pushing and pulling the mounting shaft is provided on the mounting shaft at the lower end of the sample placement box.

[0011] Preferably, the operating component includes a mounting sleeve mounted on the mounting shaft and a pull rod extending from the side wall of the mounting sleeve toward the cabinet opening and perpendicular to the mounting shaft, and a pull ring is provided at one end of the pull rod away from the mounting sleeve for easy hand force application.

[0012] By adopting the above scheme, after the operator grabs the pull ring, he can pull the pull ring outward to move the installation axis toward the cabinet opening, so that the sample placement box is partially exposed to the outside of the cabinet; by pushing the pull ring inward, the installation axis can be moved inside the cabinet, so that the sample placement box is completely inserted into the cabinet.

[0013] Preferably, both ends of the guide groove are closed ends, and the end of the mounting shaft is provided with a matching structure for facilitating disassembly and assembly with the guide groove, the matching structure comprising a groove recessed at the upper end of the mounting shaft, a telescopic section elastically retracted in the groove and partially extended and then inserted into the guide groove, and an elastic member located in the groove and driving the telescopic section to be in an extended state, and the retraction of the telescopic section is controlled by a driving component.

[0014] With the above solution, both ends of the guide groove are closed ends, which are used to limit the maximum inward and outward movement of the installation shaft, prevent the installation shaft from moving excessively outward and leaving the cabinet, and prevent the installation shaft from moving excessively inward and causing the placement box to collide with the back side of the cabinet.

[0015] Preferably, the driving component includes a driving rod extending vertically from the lower end of the outer wall of the telescopic section to form a mounting shaft, and a clearance groove provided on the outer wall of the mounting shaft for allowing the driving rod to move vertically.

[0016] By adopting the above scheme, the telescopic section can be retracted by lowering the driving rod, thereby realizing the separation of the installation shaft from the guide groove; when the driving rod is released, the telescopic section extends out under the resetting action of the elastic member and engages with the guide groove to realize the installation of the installation shaft in the solid.

[0017] Preferably, a pull rope is fixed on the driving rod to facilitate force application.

[0018] With the above solution, the installation of the pull rope makes it convenient for the operator to drive the driving rod.

[0020] By adopting the above solution, the provision of the steel ball changes the sliding friction between the end of the installation shaft and the guide groove into rolling friction, and the movement of the installation shaft is more labor-saving and smooth.

[0021] Preferably, the placement box comprises a box body with an opening upward and a placement plate snapped into place at the opening of the box body, and the placement plate is evenly provided with insertion holes for partial insertion of the sample.

[0022] By adopting the above scheme, an insert block is arranged on the placement plate, and after the sample is inserted into the insert block, the bottom thereof abuts against the bottom of the placement box. The above arrangement can limit the tipping of the sample.

[0023] Preferably, the cabinet is divided into several independent chambers by partitions, each chamber is provided with a sample placement box that can be fully accommodated in the chamber or partially extended out of the chamber, and each chamber is provided with a sealing door at the opening that can open and close the chamber, and the sealing door is provided with a handle for easy opening.

[0024] By adopting the above solution, the cabinet is divided into independent chambers, so that the samples between the chambers can be isolated.

[0025] Preferably, the inner wall of the cabinet and the side of the sealing door close to the chamber are provided with an insulation layer, and the side of the chamber away from the sealing door is a stainless steel plate with good cooling performance. A accommodating groove for placing ice cubes or ice water is formed between the stainless steel plate and the rear side plate of the cabinet. The upper and lower ends of the rear side plate of the cabinet are respectively provided with an inlet and an outlet, and the inlet and the outlet are provided with blockages.

[0026] By adopting the above scheme, the interior of the entire cabinet is in an insulated state due to the setting of the insulation layer. When ice cubes or ice water are poured into the receiving tank from the inlet, heat conduction is carried out through the stainless steel plate to reduce the temperature of each receiving cavity, and the water in the receiving tank can be discharged from the cabinet from the outlet.

[0027] The utility model adopts the above technical scheme, which has significant technical effects: the sample placement box is installed in the cabinet through the guide structure, the sample placement box is rotatably matched with the installation shaft, the installation shaft guide is set in the guide groove, and the sampler can drive the sample placement box to completely enter the cabinet or partially extend out of the cabinet by moving the installation shaft. After the sample placement box partially extends out of the cabinet, the extended part is completely exposed to the field of vision of the sampler. The sampler can fully identify the sample in the sample placement box by rotating the sample placement box, and sampling and placement are more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
