Description

Technical Field

[0001] This utility model relates to the field of thermometer sleeve technology, and in particular to an enamel thermometer sleeve. Background Technology

[0002] Enameled thermometer sleeves refer to thermometer sleeves whose outer shell is made of enamel (also known as glass enamel). Glass enamel thermometer sleeves act as baffles during stirring, reducing reaction time and improving efficiency. They have a simple structure, are easy to install and operate, can be firmly fixed, are safe and reliable, ensure stable production, and have good application performance. However, when using the sleeve, the thermometer is installed inside. When the thermometer is not inserted into the sleeve, foreign objects can easily enter because the sleeve itself does not have a shielding structure at the port. When the thermometer is inserted into the sleeve, it is easily damaged by foreign objects. Utility Model Content

[0003] The main objective of this invention is to provide an enamel thermometer sleeve that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An enamel thermometer sleeve includes a sleeve body and is characterized by further including a gasket installed on the sleeve body. A closing block for blocking the port of the sleeve body is movably installed inside the gasket. A semi-circular ring flush with the upper surface of one side of the gasket is embedded, and a fastener for mounting the closing block is embedded on the upper surface of the other side of the gasket.

[0006] The upper surface of one side of the washer ring has an arc-shaped groove for mounting a semi-circular ring. The inside of the washer ring has a through-hole for the rotation of the closing block. The lower surface of the inside of the through-hole has a threaded groove adapted to the fastener. The upper surface of the other side of the washer ring has a mounting hole for hiding the fastener. The lower surfaces of both ends of the arc-shaped groove have L-shaped stop grooves to limit the vertical movement distance of the semi-circular ring.

[0007] The lower surfaces at both ends of the semicircular ring are fitted with L-shaped stops to limit the movement of the closing block.

[0008] The rear surface of the closing block is fitted with a collar that is sleeved on the surface of the fastener. The diameter of the closing block is larger than the inner diameter of the washer. The part of the fastener that is embedded in the threaded groove is threaded. The inner diameter of the washer is equal to the inner diameter of the port of the sleeve body.

[0009] Compared with the prior art, this utility model proposes an enamel thermometer sleeve, which has the following beneficial effects:

[0010] In this invention, by setting a gasket, space can be provided for the installation of the semi-circular ring and the closing block.

[0011] The closing block can be installed and removed using fasteners. After installation, the closing block can rotate on the surface of the fastener, thereby blocking the port of the sleeve body and preventing foreign objects from entering the interior of the sleeve body.

[0012] By using a semi-circular ring, after the closing block blocks the port of the casing body, pressing the semi-circular ring downwards can limit the closing block blocking the port of the casing body using an L-shaped stop, preventing the port of the casing body from being exposed due to the rotation of the closing block.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] like Figure 1-4 As shown, an enamel thermometer sleeve includes a sleeve body 1, and is characterized by a washer 2 installed on the sleeve body 1. A closing block 4 that blocks the port of the sleeve body 1 is movably installed inside the washer 2. A semi-circular ring 3 that is flush with the upper surface of the washer 2 is embedded on one side of the upper surface of the washer 2, and a fastener 5 that installs the closing block 4 is embedded on the upper surface of the other side of the washer 2.

[0022] In a preferred embodiment: an arc-shaped groove 201 for mounting a semi-circular ring 3 is provided on the upper surface of one side of the washer ring 2, an opening 202 for rotating the closing block 4 is provided inside the washer ring 2, a threaded groove 203 adapted to the fastener 5 is provided on the lower surface of the opening 202, an mounting hole 204 for hiding the fastener 5 is provided on the upper surface of the other side of the washer ring 2, and L-shaped stop grooves 205 for limiting the vertical movement distance of the semi-circular ring 3 are provided on the lower surfaces of both ends of the arc-shaped groove 201.

[0023] In the above structure, when the closing block 4 rotates into the inside of the gasket 2 and blocks the port of the sleeve body 1, the L-shaped stop 301 of the semi-circular ring 3 is disengaged from the L-shaped stop groove 205 by pressing down the semi-circular ring 3. When the semi-circular ring 3 is embedded in the arc groove 201, the semi-circular ring 3 uses the L-shaped stop 301 to limit the closing block 4, so that the closing block 4 can maintain the state of blocking the port of the sleeve body 1.

[0024] In a preferred embodiment, L-shaped stops 301 for limiting the closing block 4 are installed on the lower surfaces of both ends of the semi-circular ring 3.

[0025] In the above structure, since the L-shaped stop 301 of the semicircular ring 3 can move up and down in the L-shaped groove 205, there is a certain friction between the two. The coefficient of friction between the L-shaped stop 301 and the L-shaped groove 205 can ensure that the semicircular ring 3 will not move under the action of gravity or a small external force after it moves up and down. In this way, after the semicircular ring 3 moves down, the L-shaped stop 301 can always keep the closed block 4 in a limited position.

[0026] In a preferred embodiment: a collar 401 is fitted onto the rear surface of the closing block 4 and sleeved on the surface of the fastener 5. The diameter of the closing block 4 is larger than the inner diameter of the washer 2. The part of the fastener 5 that is embedded in the threaded groove 203 is threaded. The inner diameter of the washer 2 is equal to the inner diameter of the port of the sleeve body 1.

[0027] In the above structure, since the closing block 4 is fitted on the surface of the fastener 5, and the part of the fastener 5 embedded in the threaded groove 203 is threaded, the closing block 4 can rotate on the surface of the fastener 5 outside the threaded groove 203 without being affected by the thread of the fastener 5. Also, since the diameter of the closing block 4 is larger than the inner diameter of the washer 2, and the inner diameter of the washer 2 is equal to the inner diameter of the port of the sleeve body 1, the closing block 4 can be used to better shield the port of the sleeve body 1.

[0028] When using this invention, when the thermometer is removed from the sleeve body 1, the closing block 4 can be rotated so that it is placed in the opening 202 of the gasket ring 2. Then, the semi-circular ring 3 is pressed down. When the semi-circular ring 3 is embedded in the arc groove 201, the semi-circular ring 3 uses the L-shaped stop block 301 to limit the closing block 4. This keeps the closing block 4 in a state of blocking the port of the sleeve body 1, thereby preventing foreign objects from entering the interior of the sleeve body 1. When the sleeve body 1 needs to be used, the semi-circular ring 3 is pulled up and the closing block 4 is rotated out of the opening 202 and placed. In this way, the thermometer can be reinserted into the sleeve body 1.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
