Description

TECHNICAL FIELD

[0002] In chemical experiments, industrial production and scientific research activities, the safe storage of chemical reagents is crucial. The traditional chemical reagent storage device usually adopts fixed slot or simple separation structure, which has the following technical defects:

[0003] Single limiting mode: Most devices only provide horizontal separation or vertical support, lacking multi-dimensional limiting of the top, bottom and circumference of the reagent bottle, leading to easy tipping and collision of the reagent bottle when subjected to external vibration or tilting, especially bottle breakage or reagent leakage caused by jolting during transportation.

[0004] Insufficient buffer protection: The buffer structure of existing devices is mostly single cushion design, without forming a systematic shockproof system. For example, only rubber pads are provided at the bottom of the storage box, ignoring horizontal impact protection, which cannot effectively respond to vibration interference in complex environments, posing a great safety hazard to volatile and reactive chemical reagents.

[0005] Poor adaptability: Traditional limiting structures are usually designed for specific specifications of reagent bottles. When storing reagent bottles of different diameters or heights, the entire limiting component needs to be replaced or adjusted, which is cumbersome and costly, and cannot meet the diversified storage needs.

[0006] Inconvenient visual management: Storage devices lacking transparent observation structure need to frequently open the box to check the reagent status, increasing the risk of reagent contact with the external environment, which may cause reagent deterioration or contamination, and reducing management efficiency.

[0007] To solve the above problems, the present application provides a limiting device for chemical reagent storage with multi-dimensional limiting, multi-level buffering and self-adaptive adjustment function. The combination of limiting arc plate and buffer spring realizes circumferential elastic clamping, combined with the flexible limiting structure of the top and bottom, forming a systematic shockproof protection system; the design of transparent observation window and lock structure takes into account the safety and convenience of the storage device, effectively solving the problems of loose limiting, insufficient buffering, poor adaptability and inconvenient management in the prior art, with significant technical progress and practical value.

[0027] In the description of the utility model, it also needs to be explained that, unless there is explicit provision and limitation, term "arrangement" "installation" "connect" "connection" should be broad understanding, for example, can be fixed connection, can be detachable connection, or integrally connected;Can be mechanical connection, can be electrical connection;It can be directly connected, can be indirectly connected through intermediate medium, can be the intercommunication of two elements inside.For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to specific circumstances.

[0028] The utility model will be further explained in detail in conjunction with example:

[0029] Example 1

[0030] As Figures 1-4The utility model provides a limiting device for chemical reagent storage, including storage box 1, the inner wall of storage box 1 is equidistant with multiple sets of limiting components 4, limiting component 4 includes the receiving base 7, the upper surface of receiving base 7 is fixedly connected with the locating collar 6 through the support column 8,

[0031] The inner wall of locating collar 6 is annularly distributed with multiple sets of limiting arc plates 9, the outer arc surface of limiting arc plate 9 is fixedly connected with buffer spring 12, the inner wall of locating collar 6 is provided with guide sliding slot 10, the inner wall of guide sliding slot 10 is movably inserted with sliding frame 11, one end of sliding frame 11 is fixedly connected with the outer arc surface of limiting arc plate 9, the end of buffer spring 12 away from limiting arc plate 9 is fixedly connected to the inner wall of locating collar 6.

[0032] The upper surface center of receiving base 7 is fixedly connected with receiving soft pad 13.

[0033] Example 2

[0034] As Figures 1-4 The utility model provides a technical scheme based on example 1: preferably, the inner arc surface of limiting arc plate 9 is fixedly connected with rubber pad 14.

[0035] The back of storage box 1 is hinged with closed protective cover 2, the inner wall top of closed protective cover 2 is fixedly connected with sponge limiting pad 5.

[0036] The front of closed protective cover 2 is fixedly connected with lock 15. The front of storage box 1 is fixedly connected with transparent observation window 3.

[0037] The working principle of the limiting device for chemical reagent storage will be described below.

[0038] As Figures 1-4 The core of the limiting device for chemical reagent storage is to realize the three-dimensional limiting and buffer protection of the chemical reagent bottle through multiple limiting components. The specific working process is as follows: when the chemical reagent bottle is placed in the limiting component 4 in the storage box 1, the bottom of the reagent bottle first contacts the receiving soft pad 13 on the upper surface of the receiving base 7, and the receiving soft pad 13 absorbs the impact force by elastic deformation. Subsequently, the outer wall of the reagent bottle enters the interior of the locating collar 6, pushing the annularly distributed limiting arc plate 9 to move outward, and the limiting arc plate 9 slides in the guide sliding slot 10 on the inner wall of the locating collar 6 through the sliding frame 11, thereby compressing the buffer spring 12.

[0039] The reverse elastic force generated by the buffer spring 12 acts on the outer wall of the reagent bottle through the limiting arc plate 9, forming a circumferential clamping force. The rubber pad 14 on the inner arc surface of the limiting arc plate 9 directly contacts the reagent bottle, and the friction characteristics of its surface can prevent the reagent bottle from rotating circumferentially, while the rubber material further buffers the lateral impact force.

[0040] When the closed protective cover 2 is closed by the hinge structure, the sponge limiting pad 5 at the top of the inner wall contacts the top of the reagent bottle, forming a top pressure limit, cooperating with the bottom receiving soft pad 13 and the circumferential limiting arc plate 9, realizing three-dimensional space limiting of the reagent bottle. The buckle 15 can firmly lock the closed protective cover 2 with the storage box 1, avoiding accidental opening during transportation or storage.

[0041] The transparent observation window 3 on the front of the storage box 1 allows the operator to directly observe the storage state of the internal reagent bottle without opening the device, improving the management efficiency.

[0042] During the entire limiting process, the elastic deformation ability of the buffer spring 12, the slidable structure of the limiting arc plate 9 and the setting of the multidirectional buffer pad jointly constitute a shockproof protection system for the chemical reagent bottle, effectively resisting the damage of external vibration or collision to the reagent bottle.

[0043] The above has made a detailed description of the general utility model, but some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, without departing from the spirit of the utility model, the modification or improvement is within the protection scope of the utility model.
