Description

Technical Field

[0001] This utility model relates to the field of reagent refrigeration equipment, and more specifically, to a refrigerated reagent cabinet. Background Technology

[0002] A refrigerated reagent cabinet is a device specifically designed for storing chemical reagents, biological samples, medicines, and other items that require low-temperature preservation.

[0003] The shelves inside the reagent cabinet are either fixed or adjustable. If a person accidentally bumps into the shelf and applies an upward force, the shelf will bounce off the support plate, causing the reagents to spill. Some support plates can hold the shelf from above and below, but these support plates need to be aligned when inserting the shelf, which is inconvenient. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a refrigerated reagent cabinet. The technical problem to be solved by the present invention is: how to enhance the stability of the adjustable shelves.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a refrigerated reagent cabinet, including a cabinet body; a shelf; a horizontally placed closing mechanism within the cabinet body, including a slide rail, a clamping plate, and a starting assembly. The slide rail is connected to the cabinet body. The starting assembly includes a first gear, a second gear, a rotating shaft, an arc-shaped wedge surface, an inner hole, and an arc-shaped wedge head. The first gear is elastically rotatably connected to the end of the slide rail. The rotating shaft, fixed to the clamping plate, rotates with the slide rail. The second gear, fixed to the rotating shaft, meshes with the first gear. The arc-shaped wedge surface is disposed in the inner hole of the first gear. The arc-shaped wedge head and the arc-shaped wedge surface, fixed to the shelf, press against each other to drive the first gear to rotate.

[0006] In a preferred embodiment, limit frames are fixed on both sides of the cabinet's inner cavity, and the slide rails are detachably connected to the limit frames via threaded fasteners.

[0007] In a preferred embodiment, the volume of the arc-shaped wedge surface and the rotating shaft each occupies one-third of the total space of the inner hole.

[0008] In a preferred embodiment, the clamp is provided with a plurality of limiting holes, and a protrusion is fixed on the side end face of the shelf, the protrusion being able to be locked into the limiting holes.

[0009] In a preferred embodiment, magnetic sheets that attract each other are fixed on both the clamp and the shelf.

[0010] In a preferred embodiment, the magnetic sheet has a volume of half that of the clamping plate, and the magnetic sheet is arranged in the rear half of the clamping plate near the interior of the cabinet.

[0011] In a preferred embodiment, the slide rail has an L-shaped cross-section, and the clamp is rotatably connected to the vertical edge of the slide rail.

[0012] In a preferred embodiment, the end of the slide rail near the outside of the cabinet is longer than the clamping plate.

[0025] Example

[0026] like Figures 1-6 A refrigerated reagent cabinet includes a cabinet body 1, a limiting frame 2, a shelf 3, and a closing mechanism 4. The cabinet body 1 is connected in series with the mains power supply. When powered on, it can continuously supply cooling to the space inside the cabinet body 1 to maintain the low temperature environment inside the cabinet body 1.

[0027] The limiting bracket 2 is a side panel fixed inside the cabinet 1 and is used to support the shelf 3.

[0028] Shelf 3 is a horizontally placed board with several appropriately sized holes for placing test tubes. Of course, shelf 3 can also be made into other shapes according to customer needs.

[0029] Shelf 3 is placed on closing mechanism 4.

[0030] The closing mechanism 4 includes a slide rail 41, a clamping plate 42, a limiting hole 43, and a starting component 44. The slide rail 41 is detachably connected to the limiting frame 2 by bolt fasteners. The slide rail 41 and the clamping plate 42 are elastically rotatably connected. The clamping plate 42 is provided with several limiting holes 43. The upper side surface of the shelf 3 is provided with a protrusion. When the limiting hole 43 is flipped to the horizontal state, the protrusion can be inserted into the corresponding limiting hole 43. In this way, the relatively closed slide rail 41 and clamping plate 42 can firmly fix the limiting hole 43 from the upper and lower sides, reducing the probability of the user accidentally pulling out the limiting hole 43.

[0031] Preferably, the slide rail 41 has an L-shaped cross-section, and the clamping plate 42 is rotatably connected to the vertical edge of the L-shape.

[0032] Furthermore, the starting assembly 44 includes a first gear 441, a second gear 442, and a rotating shaft 443. The clamping plate 42 is fixed to the rotating shaft 443, and the rotating shaft 443 rotates between the slide rail 41. The first gear 441 is rotatably connected to one end of the slide rail 41 near the inside of the cabinet 1. The rotating shaft 443 extends out of one end of the slide rail 41 and is fixed to the second gear 442. The first gear 441 and the second gear 442 mesh with each other.

[0033] Furthermore, gear 441 has an inner hole 445, and an arc-shaped wedge surface 444 is fixed on the inner wall of the inner hole 445. An arc-shaped wedge head 446 is fixed on one end of the shelf 3 near the inside of the cabinet 1. The arc-shaped wedge head 446 and the arc-shaped wedge surface 444 work together. When the arc-shaped wedge head 446 presses the arc-shaped wedge surface 444, the arc-shaped wedge surface 444 makes way to drive gear 441 to rotate. Under the meshing action, gear 441 drives the rotating shaft 443 to rotate through gear 442, so that the clamp 42 can close relative to the slide rail 41 and the protrusion is just locked in the limiting hole 43.

[0034] For example, the internal space of the inner hole 445 is divided into three equal parts, namely A, B and C. The space occupied by the arc-shaped wedge surface 444 is one of them, namely A. When the arc-shaped wedge head 446 extends into the inner hole 445 and gradually squeezes the arc-shaped wedge surface 444, the arc-shaped wedge head 446 gradually occupies space A, while the arc-shaped wedge surface 444 is squeezed into space B, and space C is empty. At this time, the clamping plate 42 deflects under the meshing transmission.

[0035] Based on this, magnetic sheets are attached to the upper side surface of shelf 3 and the corresponding surface of clamp 42.

[0036] When the clamp 42 is fully open, the distance between the clamp 42 and the side of the shelf 3 is large, and the magnetic attraction is weak. When the limiting hole 43 is tilted, the magnetic attraction increases. Under the action of the magnetic attraction, the clamp 42 closes and locks the shelf 3 in the slide rail 41 and the clamp 42. At this time, the gear 2 442 will drive the gear 1 441 to rotate accordingly, and the arc-shaped wedge surface 444 moves into the C space following the gear 1 441.

[0037] When it is necessary to open the clamp 42, the clamp 42 is flipped up by manual force, the gear 441 reverses, and then the shelf 3 is manually pulled out from the slide rail 41. At the same time, the gear 441 resets under the action of elastic force, and the clamp 42 is fully opened.

[0038] Preferably, the magnetic sheet is only present in the rear half of the clamping plate 42, that is, close to the interior of the cabinet 1, so that there is no magnetic attraction interference when the shelf 3 is aligned with the slide rail 41 in the early stage.

[0039] Preferably, the length of the slide rail 41 is greater than the length of the clamping plate 42, especially at the end near the outer side of the cabinet 1, the longer slide rail 41 makes it easier for the shelf 3 to find the desired placement position.

[0040] In summary:

[0041] This application uses the activation component 44 structure to allow the slide rail 41 and clamp 42 to close at the appropriate time, thereby limiting the shelf 3 and maintaining the stability of the shelf 3 position.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
