Description

Technical Field

[0001] The utility model belongs to the technical field of thermometer sealing protection, in particular to a sealing sleeve cap used for fixing a thermometer. Background Art

[0002] A thermometer is a tool that can accurately measure temperature. According to the temperature range of use, thermometers with various ranges have been designed and manufactured. In chemical experiments, thermometers are often used to detect the temperature of chemical reactions or steam temperatures.

[0003] Existing thermometer fixing devices include silicone plugs and thermometer caps. Silicone plugs are inconvenient to use and require a lot of force to insert, which may cause the risk of breaking the mouth of the glass bottle. At the same time, as the reaction temperature increases, the steam in the reactor increases, the pressure increases, and the silicone plug may pop out, resulting in the loss of reactants and products. Thermometer caps are currently the most widely used thermometer fixing components. The problem with thermometer caps currently on the market is that they have a hollow internal structure, and raw materials and product steam condensate remain on the inner wall of the glass, resulting in waste of precious reagents and product loss, reducing the efficiency of the chemical reaction. Summary of the invention

[0004] The utility model provides a sealing cap for fixing a thermometer, which is used to solve the technical problem that condensate is accumulated or remains in the thermometer caps on the market, thus causing waste of precious reagents.

[0005] To achieve the above object, the utility model provides the following technical solutions: a sealing cap for fixing a thermometer, comprising a sealing cap assembly arranged on the outside of the thermometer, wherein the outside of the thermometer further comprises a sealing cap assembly;

[0006] The sealing sleeve cap assembly includes a glass sleeve slidably arranged on the outside of the thermometer, a threaded tube is fixedly arranged on the top of the glass sleeve, a cap is spirally arranged on the outside of the threaded tube, a glass seal is fixedly arranged on the bottom of the glass sleeve, and a plastic hollow sleeve and a rubber gasket are arranged on the outside of the thermometer and located inside the glass sleeve;

[0007] The plastic hollow sleeve, the rubber gasket and the thermometer are sleeved together. The plastic hollow sleeve is on the rubber gasket, and the rubber gasket is tightly pressed against the glass seal.

[0008] Preferably, a through opening is provided at the center of the bottom seal of the glass sleeve, and the thermometer passes through the through opening of the glass seal.

[0009] Preferably, the upper half of the glass sleeve is set to transparent glass, and the lower half of the glass sleeve is set to frosted glass.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model adopts a sealing structure composed of a glass seal and a rubber gasket arranged at the bottom of the cap assembly. For chemical experiments, especially when the raw materials are scarce and expensive, or when the reaction yield is required to be high, this sealed thermometer cap will seal the bottom, and the product steam cannot enter the thermometer cap, thereby reducing the residue of condensed products and improving the yield.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 3 As shown, the utility model provides a sealing cap for fixing a thermometer, comprising a thermometer 1, and a sealing cap assembly 2 is further provided on the outer side of the thermometer 1;

[0020] The sealing sleeve cap assembly 2 includes a glass sleeve 21 slidably arranged on the outside of the thermometer 1, a threaded tube 22 is fixedly arranged on the top of the glass sleeve 21, a cap 24 is spirally arranged on the outside of the threaded tube 22, a glass seal 25 is fixedly arranged on the bottom end of the glass sleeve 21, the outside of the thermometer 1 is located inside the glass sleeve 21 and a plastic hollow sleeve 23 is sleeved, the outside of the threaded tube 22 is spirally arranged on the outside of the threaded tube 22, and the cap 24 is installed on the outside of the threaded tube 22 for positioning, so that the plastic hollow sleeve 23 can be pressed into the inside of the glass sleeve 21, and a glass seal 25 is fixedly arranged on the bottom end of the glass sleeve 21, and the outside of the thermometer 1 is located inside the glass sleeve 21 and a plastic hollow sleeve 23 is sleeved.

[0021] Specifically, a through opening is opened at the center of the glass seal 25 , and the thermometer 1 passes through the through opening of the glass seal 25 . The thermometer 1 is passed through the bottom through opening of the glass seal 25 , and can be used through the glass seal 25 .

[0022] Furthermore, the upper half of the glass sleeve 21 is set to transparent glass, and the lower half of the glass sleeve 21 is set to frosted glass, so as to facilitate observation operation through the glass sleeve 21.

[0023] The plastic hollow sleeve 23 and the rubber gasket 26 are sleeved with the thermometer 1. The plastic hollow sleeve 23 is on the rubber gasket 26 and penetrates the glass sleeve 21. The cap is put on the upper end of the thermometer and tightened. The bottom end of the plastic hollow sleeve 23 presses the rubber gasket 26 downward, so that the rubber gasket 26 is tightly pressed against the glass seal 25, and the sealing effect is enhanced by the rubber gasket 26.

[0024] Among them, the thermometer 1 is the existing technology and will not be described in detail. The appropriate range can be selected according to the use temperature. At the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0025] Working principle and process:

[0026] The staff sleeves the plastic hollow sleeve 23 and the rubber gasket 26 in the sealing sleeve cap assembly 2 on the outside of the thermometer 1, with the plastic hollow sleeve 23 on the rubber gasket 26, and then inserts the assembled thermometer 1 from top to bottom into the glass sleeve 21, passes the thermometer 1 through the glass seal 25, adjusts the height of the thermometer by pushing the thermometer 1 or adjusting the position of the rubber gasket 26, sleeves the cap 24 on the upper end of the thermometer, and tightens it to the outside of the threaded tube 22. At this time, the thermometer 1 is fixed. If the height is not appropriate and needs to be adjusted, loosen the cap 24, adjust the height of the thermometer 1, and finally tighten the cap 24. The operation is simple and convenient. In the process of use, for chemical experiments, especially when the raw materials are scarce and expensive, or when the reaction yield is required to be high, the thermometer sleeve cap with a bottom seal prevents the product vapor from entering the glass sleeve 21, reduces the residual condensed product, and also reduces the internal volume of the reactor, thereby reducing the retention of product vapor, thereby achieving the purpose of increasing the yield.
