Description

Technical Field

[0001] The utility model relates to the technical field of laboratory instruments, and more specifically, to a low-temperature magnetic stirring cabinet. Background Art

[0002] In modern chemistry, biology, materials science and other fields, low-temperature magnetic stirring cabinet, as an important laboratory equipment, plays a key role in sample preparation, reaction mixing and temperature control. It can effectively stir samples magnetically in a low-temperature environment to ensure the uniformity and controllability of the experimental process. First of all, in the existing technical means, low-temperature magnetic stirring cabinets usually use fixed support feet to support the stirring cabinet body. Although this design is simple and easy, it has certain limitations in actual use. When the stirring cabinet is placed on an uneven ground or work surface, the fixed support feet cannot adapt well to the unevenness of the ground, resulting in the unstable placement of the stirring cabinet, which is prone to shaking or tilting. This not only affects the stability and accuracy of the experimental process, but may also cause safety hazards such as sample overflow or equipment damage. Especially in some precision experiments or long-term continuous stirring scenarios, the stability of the stirring cabinet is particularly critical.

[0003] In addition, in the daily use and maintenance of the low-temperature magnetic stirring cabinet, the installation of the base plate is a common operation. The base plate is an important component of the stirring cabinet, which plays a supporting and protective role. However, the base plate installation operation in existing devices is often cumbersome and inconvenient. Many stirring cabinets use bolt fixing or snap connection to install the base plate, which requires the use of special tools, such as screwdrivers or screwdrivers, resulting in low installation efficiency.

[0004] Secondly, the base plate needs to be disassembled regularly for cleaning and maintenance. When disassembling the base plate, tools are needed to loosen the bolts or buckles. The operation is time-consuming, labor-intensive and very cumbersome. In addition, the buckles or base plate may be easily damaged during the disassembly process. The inconvenience of disassembling the base plate not only affects the user's operating experience, but also reduces the efficiency of equipment maintenance. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a low-temperature magnetic stirring cabinet, which has the following beneficial effects:

[0018] 1. The supporting device includes a supporting cylinder, a rotating sleeve, a supporting rod, a clamping block, a top sleeve and other components. By arranging a movable supporting rod under the bottom plate and cooperating with the rotating sleeve and the top sleeve, the height of the supporting rod can be flexibly adjusted. When the mixing cabinet is placed on an uneven ground or work surface, the supporting rod can be adaptively extended and retracted to ensure the stable placement of the mixing cabinet.

[0019] 2. The installation device adopts components such as a movable sleeve, a plug-in sleeve, a connecting rod, and a card block. The quick connection between the base plate and the magnetic cabinet is realized by the engagement of the card block with the card slot. The movable sleeve can pass through the base plate and extend into the plug-in sleeve. The card block is stably engaged with the card slot under the action of the first spring, thereby stably installing the base plate on one side of the magnetic cabinet. This design simplifies the installation operation of the base plate, eliminates the need for special tools, and greatly improves the installation efficiency. At the same time, the cooperation between the movable sleeve and the plug-in sleeve also ensures the reliability of the base plate installation and avoids loosening or falling off during use.

[0020] 3. The disassembly mechanism includes a second spring and a handle. The cooperation of the conical block and the second spring realizes the smooth separation of the card block and the card slot. By pulling the handle, the card rod drives the conical block to move. Under the action of the second spring, the card block gradually separates from the card slot and is finally pulled out of the plug sleeve to complete the removal of the base plate. This design cleverly utilizes the structural characteristics of the conical block and the spring to realize the rapid disassembly of the base plate without the aid of tools. The operation is simple and convenient. At the same time, the disassembly process is smooth and controllable, avoiding damage to the buckle or the base plate, and improving the maintainability of the equipment.

When the guide block 11 moves to the top of the guide groove 12, the rotation of the rotating sleeve 7 is stopped. At this time, the clamping block 9 will press the side wall of the support rod 8 through the rubber pad 21 arranged on the inside, thereby preventing the support rod 8 from sliding easily, thereby ensuring the stability of the equipment. Then, the liquid is put into the glass dish, and then the glass dish is placed on the placing table 2. Then, the magnetic rotor is placed at the bottom of the glass dish, and the switch 4 is turned on. The device is brought into contact with the glass dish through the existing technical means.

Due to the special structural design of the conical block 29, the clamping rod 25 A certain space will be reserved on the side walls of the block 27 and the conical block 29. When the clamping rod 25 compresses the first spring 30 to the limit, the clamping block 27 is pressed into the movable sleeve 22 by hand, and the outer side of the clamping block 27 will remain flush with the side wall of the movable sleeve 22. Then the movable sleeve 22 and the clamping rod 25 are extended through the bottom plate 5 into the plug-in sleeve 26. Then the clamping rod 25 is released, and the clamping rod 25 and the fixed plate 24 are pressed inwardly. When the fixed plate 24 contacts the bottom plate 5, the position of the clamping block 27 corresponds to the position of the slot 28.
