[0041] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0042] See also Figure 1 , Figure 3 The utility model provides a height-adjustable reagent rack, including a base 1, two support frames 2 and at least one layer unit 3. The two support frames 2 are arranged at intervals from each other and are both connected to the base 1. The layer unit 3 includes a layer 31, two sliding members 32 and two clamping members 33. The layer 31 is arranged between the two support frames 2. The two sliding members 32 are respectively arranged at both ends of the layer 31 and are both connected to the layer 31. One end of the clamping member 33 is slidably connected to the sliding member 32 and the other end is clamped with the support frame 2, and the clamping member 33 can slide relative to the sliding member 32 and the layer 31 along the height direction of the support frame 2.

[0043] In this device, two support frames 2 spaced apart from each other are arranged on the base 1, and at least one layer plate unit 3 is arranged between the two support frames 2, wherein the layer plate 31 is connected to the support frame 2 via sliding members 32 and clamping members 33 distributed at both ends thereof, and the sliding member 32 can slide relative to the clamping member 33 along the height direction of the support frame 2, and one end of the clamping member 33 is slidably connected to the sliding member 32, and the other end is clamped to the support frame 2.

[0044] Compared with the prior art, the clamping connection between the clamping piece 33 and the support frame 2 replaces the threaded connection in the conventional setting, thereby avoiding repeated disassembly and assembly of the self-tapping screws to move the layer plate 31. At the same time, the clamping piece 33 can slide relative to the sliding piece 32 and the layer plate 31 along the height direction of the support frame 2, so that the layer plate 31 can continue to slide relative to the clamping piece 33 after its height is fixed by the clamping piece 33, so as to perform fine adjustment of the height, thereby avoiding repeated disassembly and assembly of the self-tapping screws to move the layer plate 31. This can solve the technical problem in the prior art that the layer plate 31 must be moved by disassembling and assembling the self-tapping screws when adjusting its height position, and repeated disassembly and assembly may cause the threaded connection position to be easily damaged.

[0045] Furthermore, the base 1 in the present device is a plate body, which has the function of increasing the counterweight and at the same time can increase the stability of the experimental frame to avoid safety hazards such as tipping over. At the same time, the middle plate 31 in the present device is a glass plate for placing experimental instruments, which has the characteristics of high strength and dirt resistance. The layer plate 31 here belongs to the conventional setting known to technical personnel in this field and will not be described in detail.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, the support frame 2 includes a first support rod 21 , a second support rod 22 and at least one elastic clamping portion 23 .

[0047] The first support rod 21 is vertically arranged and connected to the base 1 , and the first support rod 21 can slide close to or away from the plane where the top of the base 1 is located.

[0048] The first support rod 21 is used to connect the layer plate 31 and can slide closer to or away from the plane where the top of the base 1 is located, so as to realize the upgrading function of the layer plate 31 relative to the base 1 to meet different usage scenarios.

[0049] As an implementation method, Figure 4 As shown, the second support rod 22 is vertically arranged, one end of the second support rod 22 is connected to the base 1, and the other end is provided with a through hole along its axis. The outer wall of the second support rod 22 is also provided with a plurality of snap-in holes connected to the through hole, and the plurality of snap-in holes are arranged along the axis of the second support rod 22. The first support rod 21 is slidably inserted at the other end of the second support rod 22, and the elastic snap-in portion 23 is connected to the first support rod 21 and can be snap-fitted with the snap-in hole.

[0050] The height adjustment of the first support rod 21 relative to the second support rod 22 can be achieved by the matching engagement of the elastic engaging portion 23 and the engaging hole.

[0051] Specifically, in the present device, a receiving groove is provided on the first support rod 21, and the elastic clamping portion 23 is arranged relative to the clamping hole and is slidably connected to the receiving groove. When the receiving groove is aligned with the clamping hole, the elastic restoring force of the elastic clamping portion 23 pushes it into the clamping hole and clamps it with the clamping hole, so that the first support rod 21 cannot slide relative to the second support rod 22.

[0052] Furthermore, when the first support rod 21 needs to be adjusted to slide relative to the second support rod 22, the user only needs to press the elastic clamping portion 23 to separate it from the clamping hole and slide it into the receiving groove. At this time, the first support rod 21 can slide relative to the second support rod 22.

[0053] Furthermore, the elastic clamping portion 23 is a spring lock pin that is common and easy to purchase on the market, and is a conventional setting known to those skilled in the art. The number of the elastic clamping portions 23 can be selected according to usage, and will not be elaborated on herein.

[0054] like Figures 1 to 4 As shown, the interior of the first support rod 21 is hollow, and a plurality of snap-in grooves are provided on one side wall of the first support rod 21, which are connected to the interior of the first support rod 21. The snap-in member 33 includes a snap-in block 331 and at least two snap-in hooks 332, the snap-in block 331 is slidably connected to the sliding member 32, and one end of the snap-in hook 332 is connected to the snap-in block 331, and the other end is snap-in matched with the snap-in groove.

[0055] The clamping block 331 connects the clamping hook 332 and the sliding member 32. Through the cooperation between the clamping hook 332 and the clamping groove, the layer plate 31 can be detachably installed between the two first support rods 21, which is convenient for users to operate and avoids repeated disassembly and assembly of self-tapping screws.

[0056] As an implementation method, Figure 5 As shown, the latching hook 332 is in a horizontally placed "L" shape.

[0057] The horizontally placed "L" shape cooperates with the snap-in groove to form a snap-in structure. Under the action of the gravity of the layer plate 31, it can provide pressure so that the snap-in hook 332 is tightly hooked in the snap-in groove. When the external force lifts the layer plate 31, the snap-in hook 332 is separated from the snap-in groove, and the snap-in hook 332 can be easily removed from the snap-in groove. The structure is simple and the operation is convenient.

[0058] As a preferred implementation method, Figure 2 As shown, multiple snap-in grooves are distributed in two adjacent rows along the height direction of the first support rod 21, and there are multiple snap-in hooks 332 in the snap-in groove snap-in member 33. The multiple snap-in hooks 332 are evenly distributed on both sides of the snap-in block 331 and are all connected to the snap-in block 331. The two snap-in hooks 332 are respectively snap-in with the two snap-in grooves located in the same row.

[0059] The two rows of parallel locking grooves cooperate with the locking hooks 332 on both sides of the locking block 331 to improve the stability of the connection.

[0060] like Figure 2 , Figure 5 As shown, the clamping block 331 is provided with at least one threaded hole, the sliding member 32 includes a connecting plate 321 and at least one fastening connection portion 322, the connecting plate 321 is provided with a sliding groove relative to the threaded hole, the sliding groove passes through the connecting plate 321, the fastening connection portion 322 has a large diameter section and a threaded section, the threaded section of the fastening connection portion 322 passes through the sliding groove and is threadedly connected to the threaded hole, and the large diameter section of the fastening connection portion 322 is abutted against the connecting plate 321.

[0061] By adjusting the tightness between the fastening connection portion 322 and the threaded hole, the connecting plate 321 can slide relative to the clamping block 331 , thereby achieving fine adjustment of the height of the layer plate 31 .

[0062] Furthermore, the fastening connection part 322 here is a screw or bolt that is common and easy to purchase on the market, and the fastening connection part 322 here cooperates with a nut and a washer to achieve a detachable connection with the clamping block 331. This is a conventional setting known to technical personnel in this field and will not be elaborated on.

[0063] As a preferred implementation method, Figure 5 As shown, there are two threaded holes on the clamping block 331 , and the two threaded holes are arranged at intervals from each other. The fastening connection parts 322 are arranged in a one-to-one correspondence with the threaded holes and are threadedly connected to the threaded holes.

[0064] The two fastening connection parts 322 are arranged at intervals from each other to improve the connection strength between the connecting plate 321 and the clamping block 331, thereby improving the stability of the device.

[0065] As an implementation method, Figure 2 As shown, the sliding member 32 further includes a side plate 323 , and the side plate 323 is connected to the connecting plate 321 and connected to the layer plate 31 .

[0066] The side plates 323 are used to connect the connecting plate 321 and the layer plate 31 and prevent the experimental apparatus from falling from both ends.

[0067] As another implementation method, Figure 1 , Figure 3 As shown, the layer plate unit 3 further includes two anti-fall frames 34 , which are arranged opposite to each other and are respectively connected to two sides of the layer plate 31 .

[0068] The anti-fall frame 34 is used to connect the side stand 323 and the layer plate 31 and prevent the experimental apparatus from falling from both sides.

[0069] Specifically, in the present device, the user can select the number of the layer plate units 3 according to the usage, and the plurality of layer plate units 3 can be arranged in sequence and spaced apart along the height direction of the support frame 2, which will not be described in detail here.

[0070] The specific working process of the utility model is that two support frames 2 spaced apart from each other are arranged on the base 1, and at least one layer plate unit 3 is arranged between the two support frames 2, wherein the layer plate 31 is connected to the support frame 2 through sliding members 32 and clamping members 33 distributed at both ends thereof, and the sliding member 32 can slide relative to the clamping member 33 along the height direction of the support frame 2, and one end of the clamping member 33 is slidably connected to the sliding member 32, and the other end is clamped with the support frame 2. Compared with the prior art, the clamping connection between the clamping member 33 and the support frame 2 replaces the threaded connection in the conventional setting, thereby avoiding repeated disassembly and assembly of self-tapping screws to move the layer plate 31, and at the same time, the clamping member 33 can slide relative to the sliding member 32 and the layer plate 31 along the height direction of the support frame 2, so that the layer plate 31 can continue to slide relative to the clamping member 33 after its height is fixed by the clamping member 33, so as to perform fine adjustment of the height, thereby avoiding repeated disassembly and assembly of self-tapping screws to move the layer plate 31.

[0071] When in use, the user first selects the number of layer boards 31, and then respectively snaps the snap hooks 332 at both ends of the layer boards 31 into the snap grooves. When the spacing between the layer boards 31 needs to be adjusted, the user can directly lift the layer boards 31 and remove the snap hooks 332 from the snap grooves. After selecting a new installation height, the user can continue to snap the snap hooks into the snap grooves. At the same time, the user can also adjust the tightness of the fastening connection part 322 so that the connecting plate 321 can slide relative to the snap block 331, and then lock the fastening connection part 322 again after the adjustment is completed. This not only has an operational structure but is also convenient to operate.

[0072] Furthermore, the user can also press the elastic snap-in portion 23 to slide the elastic snap-in portion 23 into the receiving groove. When adjusted to a suitable height, the receiving groove is aligned with the snap-in hole, and the elastic snap-in portion 23 is automatically clamped with the snap-in hole, thereby completing the adjustment of the height of the support frame 2.

[0073] The device, through the above structure, can solve the technical problem in the prior art that the height of the layer plate 31 must be adjusted by disassembling and assembling self-tapping screws to move the layer plate 31, and repeated disassembly and assembly may cause structural damage to the threaded connection position.

[0074] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
