Description

Technical Field

[0001] This utility model relates to the field of temperature measuring protective sleeve technology, specifically a disassembly self-locking temperature measuring protective sleeve. Background Technology

[0002] Self-locking temperature measuring protective sleeves are key components in industrial temperature measurement systems used to protect temperature measuring elements, such as thermocouples, resistance temperature detectors (RTDs), and thermometers. They are widely used in various industrial equipment, pipelines, and devices that require temperature monitoring. Their core function is to isolate the temperature measuring element from direct corrosion by the measured medium, such as high temperature, high pressure, corrosive fluids, or dust. Simultaneously, the self-locking mechanism ensures stable installation and prevents detachment due to vibration, media impact, or other factors.

[0003] Existing patent document CN207379620U discloses a high-pressure temperature measurement protective sleeve, which is a machined sleeve divided into an upper part, a middle part, and a lower part. The outer side of the upper part has an external hexagonal structure, the interior of the upper part has internal threads, the outer wall of the middle part has external threads, and the bottom end of the lower part is closed. This utility model of a high-pressure temperature measurement protective sleeve can withstand high pressure, protect the detection element of the temperature gauge or temperature sensor, prevent media leakage without affecting the usable space inside the container or pipeline, and is easy to install and disassemble.

[0004] However, existing self-locking temperature measuring protective sleeves are usually assembled with the thermometer using a threaded connection. This type of protective sleeve is cumbersome to install and remove, leading to operational inefficiency. Therefore, we propose a self-locking temperature measuring protective sleeve for disassembly. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a detachable self-locking temperature measuring protective sleeve to solve the problems mentioned in the background section.

[0007] A socket unit includes a socket tube, the top end of which is integrally formed with a connecting threaded sleeve, the outer side of which is threaded with a disassembly sleeve, the top end of which is integrally formed with a snap-fit ​​sleeve, the top end of which is integrally formed with a shrink end, and the top end of which is provided with a temperature measuring needle port.

[0008] The self-locking unit includes a temperature measuring sleeve installed on the outside of the snap-fit ​​sleeve. The top of the temperature measuring sleeve has a temperature measuring screw opening, and the bottom end of the temperature measuring sleeve is integrally formed with a snap-fit ​​arm. One end of the snap-fit ​​arm is integrally formed with a snap-fit ​​block.

[0009] Preferably, the top of the disassembly sleeve is integrally formed with a pressing end, and the top of the pressing end is provided with a connecting screw.

[0010] Preferably, the extrusion end gradually increases in size from top to bottom, and the outer surface of the extrusion end is smooth.

[0011] Preferably, the bushing is a hollow structure, and the bushing is a cylindrical structure.

[0012] Preferably, there are multiple snap-fit ​​arms, all of the same size, and all of the snap-fit ​​arms are arranged at equal intervals.

[0013] Preferably, the snap-fit ​​block is triangular, and the number of snap-fit ​​blocks is the same as the number of snap-fit ​​arms. Beneficial effects

[0014] This utility model provides a detachable self-locking temperature measuring protective sleeve, which has the following advantages:

[0015] This type of self-locking temperature measuring protective sleeve, with its snap-fit ​​sleeve, shrink-fit end, snap-fit ​​arm, and snap-fit ​​block, simplifies installation. During installation, the operator inserts the temperature measuring needle through the temperature measuring threaded port of the sleeve, connecting it to the temperature measuring tube. The connecting sleeve is then threaded to the equipment. Once installed, the self-locking unit is fitted onto the shrink-fit end, allowing the temperature measuring needle to be inserted. The snap-fit ​​block of the snap-fit ​​arm is gradually opened by the shrink-fit end, locking into the lower part of the snap-fit ​​sleeve. For disassembly, the operator simply rotates the disassembly sleeve clockwise, pushing the snap-fit ​​block under the snap-fit ​​arm. The snap-fit ​​block, under pressure, opens the snap-fit ​​arm, allowing the self-locking unit to be pulled upwards, separating it from the sleeve unit. This simplifies installation and disassembly, improving operational efficiency. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a detachable self-locking temperature measuring protective sleeve, comprising,

[0023] The socket unit 1 includes a socket tube 101. A connecting screw sleeve 102 is integrally formed at the top end of the socket tube 101. A disassembly sleeve 103 is threadedly connected to the outer side of the connecting screw sleeve 102. A snap-fit ​​sleeve 106 is integrally formed at the top end of the connecting screw sleeve 102. A shrink end 107 is integrally formed at the top end of the snap-fit ​​sleeve 106. A temperature measuring needle port 108 is opened at the top end of the shrink end 107.

[0024] The self-locking unit 2 includes a temperature measuring sleeve 201 installed on the outside of the snap-fit ​​sleeve 106. The top of the temperature measuring sleeve 201 is provided with a temperature measuring screw 202. The bottom end of the temperature measuring sleeve 201 is integrally formed with a snap-fit ​​arm 203. One end of the snap-fit ​​arm 203 is integrally formed with a snap-fit ​​block 204.

[0025] Furthermore, the top of the disassembly sleeve 103 is integrally formed with a pressing end 104, and the top of the pressing end 104 is provided with a connecting screw 105. By rotating the disassembly sleeve 103 clockwise, the disassembly sleeve 103 moves upward, and the pressing end 104 can push the snap-fit ​​block 204 under the snap-fit ​​arm 203.

[0026] Furthermore, the extrusion end 104 gradually increases in size from top to bottom, and the outer surface of the extrusion end 104 is smooth. Because the extrusion end 104 gradually increases in size from top to bottom, the extrusion end 104 can extrude the snap-fit ​​block 204, and the snap-fit ​​arm 203 can expand outward.

[0027] Furthermore, the sleeve 101 has a hollow structure and is cylindrical in shape. The hollow structure of the sleeve 101 allows for better installation of the temperature measuring needle.

[0028] Furthermore, multiple snap-fit ​​arms 203 are provided, all of the same size, and are arranged at equal intervals. The snap-fit ​​arms 203 can expand outwards better, thereby achieving the snap-fit ​​function.

[0029] Furthermore, the snap-fit ​​block 204 is triangular in shape, and the number of snap-fit ​​blocks 204 is the same as that of snap-fit ​​arms 203. By attaching the self-locking unit 2 to the retractable end 107, the snap-fit ​​blocks 204 of the snap-fit ​​arm 203 can be gradually opened by the retractable end 107. Subsequently, the snap-fit ​​blocks 204 of the snap-fit ​​arm 203 are snapped together with the lower part of the snap-fit ​​sleeve 106.

[0030] Working Principle: After the utility model is installed, first check the installation, fixation, and safety protection. When installing the temperature measuring protective sleeve, the worker passes the temperature measuring needle through the temperature measuring screw port 202 of the temperature measuring sleeve 201, so that the temperature measuring screw port 202 is threadedly connected to the temperature measuring tube. Then, the connecting screw sleeve 102 is threadedly connected to the equipment. After installation, the self-locking unit 2 can be sleeved on the shrink end 107, and the temperature measuring needle can be inserted into the temperature measuring needle port 108. At this time, the locking block 204 of the locking arm 203 can be locked by the shrink end 107. 7. Gradually expand, and then the locking block 204 of the locking arm 203 is locked together with the lower part of the locking sleeve 106. When disassembly is required, the operator only needs to rotate the disassembly sleeve 103 clockwise, and the pressing end 104 can push the locking block 204 under the locking arm 203. After the locking block 204 is pressed, the locking arm 203 can be expanded. At this time, the self-locking unit 2 can be pulled upward, and the self-locking unit 2 and the sleeve unit 1 can be separated. This completes the use of this utility model. This utility model has a simple structure and is safe and convenient to use.
