Description

Technical Field

[0001] This utility model relates to the field of industrial production, and in particular to a constant temperature water bath without a cover plate for heat preservation. Background Technology

[0002] A constant temperature water bath is an instrument or device specifically designed to precisely control water temperature and maintain it at a specific constant temperature value for a long period of time.

[0003] The existing technology has the following drawbacks: Thermostatic water baths typically have an insulation layer inside, and part of this insulation layer is located around the water tank. After long-term use, this insulation layer may become damaged or its performance may degrade, requiring replacement and maintenance. However, the disassembly and assembly of the water tank and insulation layer in traditional thermostatic water baths is often complicated, usually requiring additional tools and multiple bolt tightening operations. This not only consumes a lot of time and effort but also demands a high level of expertise from the operators, causing considerable inconvenience to daily maintenance. Therefore, a coverless thermostatic water bath insulation device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a coverless insulation device for a constant temperature water bath, which aims to solve the problem of low maintenance efficiency caused by the need to use additional tools to tighten bolts multiple times in the prior art.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a constant temperature water bath without a cover, including a water bath 1. The inner wall of the water bath 1 is provided with an insulation layer 2, which is made of polyurethane foam material. It can effectively block the transfer of heat, making it difficult for the heat inside the water bath 1 to dissipate to the outside, and maintaining a relatively stable water temperature. A water tank 3 is sleeved on the inner wall of the insulation layer 2. The water tank 3 is a relatively independent and closed container structure, and its primary function is to hold water. A handle 4 is fixedly connected to the top of the water tank 3, which can be used to remove the water tank 3 from the insulation layer 2. The inner wall of the water bath 1 is provided with a limit mechanism. The inner wall of the water tank 3 is provided with an annular groove 8, which has a vertical opening, so that the protrusion 7 can enter the annular groove 8 from the opening or move out of the annular groove 8. An adjustment component is provided at the bottom of the water bath 1.

[0031] The limiting mechanism includes a rotating rod 6, which is rotatably connected to the inner wall of the water tank 1. The outer wall of the rotating rod 6 is elastically connected to the water tank 1 through a torsion spring 5. The water tank 1 has a slot for placing the torsion spring 5, which can satisfy the compression or reset of the torsion spring 5. A protrusion 7 is fixedly connected to the outer wall of the rotating rod 6.

[0032] Reference Figure 1 and Figure 5 The adjustment assembly includes a circular sleeve 9, which is rotatably connected to the inner wall of the water tank 1. A movable rod 10 is threadedly connected to the outer wall of the circular sleeve 9. The circular sleeve 9 and the movable rod 10 mainly support the entire water tank 1. The inner wall of the circular sleeve 9 has threads and the outer wall of the movable rod 10 has matching threads, which allows the movable rod 10 to move along the inner wall of the circular sleeve 9. An L-frame 11 is fixedly connected to the bottom of the water tank 1. The L-frame 11 mainly connects to guide the movable rod 10. A level 12 is installed on the outer wall of the water tank 1. The level 12 can be used to determine whether there is a height deviation in the placement of the water tank 1, which is convenient for subsequent adjustments.

[0033] The movable rod 10 is slidably connected to the inner wall of the L-frame 11.

[0034] Reference Figures 2-4 The outer wall of the rotating rod 6 is fixedly connected to one end of the torsion spring 5. When the rotating rod 6 rotates clockwise, it compresses the torsion spring 5. During reset, the elastic force of the torsion spring 5 carries the rotating rod 6 back to its original position. The other end of the torsion spring 5 is fixedly connected to the inner wall of the water tank 1. The protrusion 7 is engaged with the inner wall of the annular groove 8. The rotating rod 6 passes through the inner wall of the water tank 3. The water tank 3 has a corresponding slot for the rotating rod 6, allowing the rotating rod 6 to pass through. The inner side wall of the water tank 3 is attached to the top of the insulation layer 2, and the inner side wall of the water tank 3 is attached to the upper end of the inner surface of the water tank 1. Figure 3 and Figure 3 The inner sidewall of the water tank 3 is equipped with a sealing gasket, which can contact the inner surface of the water tank 1 to increase the sealing performance.

[0035] Working principle: First, during the placement and use of the entire water tank 1, the level 12 can be used to determine whether there is any unevenness at the four corners of the water tank 1. If it is necessary to adjust the support of one corner of the entire water tank 1, simply rotate the sleeve 9 and let the movable rod 10 move downward along the inner wall of the sleeve 9 to make the four corners of the entire water tank 1 level. This prevents a certain heating area from contacting the water more due to the tilt of the water tank 1, which would lead to local overheating while other areas are too cold, thus disrupting the overall constant temperature environment.

[0036] When the insulation layer 2 needs to be replaced, simply rotate the rotating rod 6 to rotate the protrusion 7 and compress the torsion spring 5, allowing the protrusion 7 to rotate to the vertical opening of the annular groove 8. Then, manually move the handle 4 to move the water tank 3 upwards from the insulation layer 2 and the water tank 1. Finally, release the rotating rod 6, and use the reverse elastic force of the torsion spring 5 to reset the rotating rod 6 and the protrusion 7, removing the entire insulation layer 2 from the inner wall of the water tank 1. Then, install the new insulation layer 2 inside the water tank 1 using existing technology. When inserting water tank 3, simply insert the entire water tank 3 into the insulation layer 2 from top to bottom, allowing the upper part of the rotating rod 6 to pass through the groove of water tank 3, so that the inner side wall of water tank 3 contacts the top of protrusion 7. Then, rotate the rotating rod 6 as described above, rotating it along with protrusion 7, so that protrusion 7 and the vertical opening of the annular groove 8 coincide. Then, press the entire water tank 3 downwards, allowing protrusion 7 to enter the vertical opening of the annular groove 8. Due to the elastic force of the torsion spring 5, the rotating rod 6 and protrusion 7 are reset, allowing protrusion 7 to be positioned... Figure 4 The status indicates that the entire disassembly and assembly process has been completed.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
