[0002] Thermocouple is a commonly used temperature measuring element in temperature measuring instruments. It directly measures temperature and converts temperature signals into thermoelectric potential signals, which are then converted into the temperature of the measured medium through electrical instruments (secondary instruments). The appearance of various thermocouples is often very different due to needs, but their basic structure is roughly the same. They are usually composed of main parts such as hot electrodes, protective sleeves and junction boxes. They are usually used in conjunction with display instruments, recording instruments and electronic regulators. When using thermocouple protective sleeves to detect gasifiers, it is often necessary to use thermocouple protective sleeves of different lengths to detect the temperature of different gasifiers.
[0003] In this regard, China applied for patent number: CN218496272U, which discloses a thermocouple protection sleeve, which relates to the technical field of thermocouple protection equipment, including a long tube of the protection sleeve, the bottom surface of the long tube of the protection sleeve is fixedly connected with an external slotted tube, the outer surface of the long tube of the protection sleeve is fixedly connected with a fixed plate, the outer surface of the external slotted tube is slidably connected with a temperature measuring tube and a temperature measuring barrel, and the temperature measuring tube and the temperature measuring barrel are provided with two pressing mechanisms on the outside, and the two pressing mechanisms both include a pressing plate, and the side where the two pressing plates are close to each other is provided with a limiting mechanism. It can press the pressing plate to the side where the two pressing plates are close to each other, which can drive the limiting rubber plate to release the limit on the external slotted tube, so that the temperature measuring tube and the temperature measuring barrel can be moved up and down, and the pressing plate can be released again, so that the limiting rubber plate can limit the external slotted tube again, and the height adjustment of the temperature measuring tube and the temperature measuring barrel is completed, so as to achieve the effect of detecting gasifiers of different heights and improve the practicality of the device.
[0004] However, in actual use, the overall protective sleeve cannot be adjusted up and down during use. At the same time, the subsequent adjustment and extension of the temperature measuring tube is troublesome to operate and has certain limitations. Therefore, it has become an urgent problem to be solved for us to perfect and improve the above problems. Utility Model Content
[0005] The purpose of the utility model is to provide a gasifier thermocouple protection sleeve to solve the problem that the integral protection sleeve proposed in the above background technology cannot be adjusted up and down during use, and the operation of the temperature measuring tube is troublesome when it is subsequently adjusted and extended, which has certain limitations.
[0006] To achieve the above object, the utility model provides the following technical solutions: a gasifier thermocouple protection sleeve, comprising a thermocouple junction box, a first sleeve is arranged at the lower end of the thermocouple junction box, a slide groove is provided on both the left and right surfaces of the first sleeve, a first slider is arranged inside the slide groove, a second sleeve is arranged on the right surface of the first slider, and the first slider and the slide groove are adapted to each other;
[0007] An adapting groove is provided on the left side surface of the first slider, a limiting groove is provided on the inner side wall of the first slider, a rotating column is provided inside the limiting groove, a first auxiliary ball is provided on the back side of the rotating column, a spring body is provided on the right side surface of the first auxiliary ball, and the spring body is installed inside the adapting groove.
[0008] Preferably, a second sliding block is provided on one side of the inner wall of the second sleeve, and a second auxiliary ball is provided inside the second sliding block.
[0009] Preferably, a first top block is disposed on the front surface of the first sleeve, and a telescopic cylinder is disposed at the lower end of the first top block.
[0010] Preferably, a friction sleeve is provided inside the telescopic cylinder, and a telescopic column is provided inside the friction sleeve.
[0011] Preferably, a second top block is provided at the lower end of the friction sleeve, and the back surface of the second top block is mounted on the front surface of the second sleeve.
[0012] Preferably, a temperature measuring tube body is provided at the lower end of the second sleeve, and the friction sleeve and the telescopic tube are adapted to each other.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The thermocouple protection sleeve of the gasifier is provided with a thermocouple junction box, a first sleeve, a slide groove, a first slider, a second sleeve, an adapter groove, a limit groove, a rotating column, a first auxiliary ball, a spring body, a second slider and a second auxiliary ball. When in use, the first slider moves inside the slide groove, and the thermocouple can be protected by the cooperation of the first sleeve and the second sleeve. When the length of the first sleeve and the slide groove needs to be adjusted, the second sleeve is held and then the second sleeve is pulled upward or downward. At this time, the first slider moves inside the slide groove, and the overall sliding effect is better. Then, the first auxiliary ball inside the first slider The ball will hit the outer surface of the first sleeve. The design of the rotating column and the first auxiliary ball can assist the first slider to move. At the same time, the rotating column is limited inside the limiting groove as a whole and will not fall off as a whole. When the first slider finishes moving, the spring body will squeeze the first auxiliary ball, so that the first auxiliary ball will hit the outer surface of the first sleeve, so that the position between the second sleeve and the first sleeve is relatively stable. Similarly, the second slider and the second auxiliary ball can assist the second sleeve to adjust and slide. Therefore, this design can facilitate the adjustment of the extension and retraction between the first sleeve and the second sleeve. The overall protection effect is good, which reflects the practicality of the design.
[0015] 2. The thermocouple protection sleeve of the gasifier is provided with a first top block, a telescopic cylinder, a friction sleeve, a telescopic column, a second top block and a temperature measuring tube and temperature measuring cylinder body. When the first sleeve and the second sleeve are telescopically adjusted, the friction sleeve will also be telescopically adjusted inside the telescopic cylinder. Since the friction sleeve and the telescopic cylinder have great friction, when the friction sleeve stops moving, the inner wall of the telescopic cylinder and the outer surface of the friction sleeve fit more stably as a whole. Therefore, after the second sleeve is adjusted, the position of the temperature measuring tube and temperature measuring cylinder body can also be telescopically adjusted, so that different gasifiers can be adapted through the temperature measuring tube and temperature measuring cylinder body, which reflects the functionality of the design.

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.
[0023] See also Figure 1-5 , an embodiment provided by the utility model:
[0024] A gasifier thermocouple protection sleeve. The thermocouple junction box 1, telescopic cylinder 14, friction sleeve 15 and temperature measuring tube and temperature measuring tube body 18 used in the present application are all products that can be directly purchased on the market. Their principles and connection methods are all existing technologies well known to those skilled in the art, so they will not be repeated here. It includes a thermocouple junction box 1, a first sleeve 2 is arranged at the lower end of the thermocouple junction box 1, and a slide groove 3 is provided on the left and right surfaces of the first sleeve 2. A first slider 4 is arranged inside the slide groove 3, and a second sleeve 5 is arranged on the right side surface of the first slider 4. The first slider 4 and the slide groove 3 are adapted to each other. A second slider 11 is arranged on one side of the inner wall of the second sleeve 5, and a second auxiliary ball 12 is arranged inside the second slider 11. A first top block 13 is arranged on the front surface of the first sleeve 2, and a telescopic cylinder 14 is arranged at the lower end of the first top block 13. A friction sleeve 15 is provided inside the contraction tube 14, a telescopic column 16 is provided inside the friction sleeve 15, a second top block 17 is provided at the lower end of the friction sleeve 15, the back of the second top block 17 is installed on the front surface of the second sleeve 5, a temperature measuring tube temperature measuring tube body 18 is provided at the lower end of the second sleeve 5, the friction sleeve 15 and the telescopic tube 14 are adapted to each other, when the first sleeve 2 and the second sleeve 5 are telescopically adjusted, the friction sleeve 15 will also be telescopic inside the telescopic tube 14, due to the large friction between the friction sleeve 15 and the telescopic tube 14, when the friction sleeve 15 stops moving, the inner wall of the telescopic tube 14 and the outer surface of the friction sleeve 15 are in overall fit and stable, so that when the second sleeve 5 is adjusted, the position of the temperature measuring tube temperature measuring tube body 18 can also be telescopic, so that different gasifiers can be adapted through the temperature measuring tube temperature measuring tube body 18;
[0025] An adapting groove 6 is provided on the left side surface of the first slider 4, a limiting groove 7 is provided on the inner side wall of the first slider 4, a rotating column 8 is provided inside the limiting groove 7, a first auxiliary ball 9 is provided on the back of the rotating column 8, a spring body 10 is provided on the right side surface of the first auxiliary ball 9, and the spring body 10 is installed inside the adapting groove 6. The first slider 4 will move inside the slide groove 3. The thermocouple can be protected by the cooperation of the first sleeve 2 and the second sleeve 5. When the length of the first sleeve 2 and the slide groove 3 needs to be adjusted, the second sleeve 5 is held and then the second sleeve 5 is pulled upward or downward. At this time, the first slider 4 will move inside the slide groove 3, and the overall sliding effect is better. After that, the first auxiliary ball 9 inside the first slider 4 will contact the outer surface of the first sleeve 2. The design of the rotating column 8 and the first auxiliary ball 9 can assist the first slider 4 to move. At the same time, the rotating column 8 is limited in the limiting groove 7 as a whole and will not fall off as a whole. When the first slider 4 finishes moving, the spring body 10 will squeeze the first auxiliary ball 9, so that the first auxiliary ball 9 will contact the outer surface of the first sleeve 2, so that the position between the second sleeve 5 and the first sleeve 2 is relatively stable. Similarly, the second slider 11 and the second auxiliary ball 12 can assist the second sleeve 5 to adjust and slide. Therefore, this design can facilitate the adjustment of the extension and retraction between the first sleeve 2 and the second sleeve 5, and the overall protection effect is better.
[0026] Working principle: When the staff uses the device, firstly, the device is connected to an external power supply to provide power support for the device, and the first slider 4 will move inside the slide groove 3, and the thermocouple can be protected by the cooperation of the first sleeve 2 and the second sleeve 5. When the length of the first sleeve 2 and the slide groove 3 needs to be adjusted, the second sleeve 5 is held and then pulled up or down. At this time, the first slider 4 will move inside the slide groove 3, and the overall sliding effect is good. Then, the first auxiliary ball 9 inside the first slider 4 will contact the outer surface of the first sleeve 2. The design of the rotating column 8 and the first auxiliary ball 9 can assist the first slider 4 to move. At the same time, the rotating column 8 is limited inside the limiting groove 7 as a whole and will not fall off as a whole. When the first slider 4 finishes moving, the spring body 10 will squeeze the first auxiliary ball 9, thereby The first auxiliary ball 9 will contact the outer surface of the first sleeve 2, so that the position between the second sleeve 5 and the first sleeve 2 is relatively stable. Similarly, the second slider 11 and the second auxiliary ball 12 can assist the second sleeve 5 to adjust and slide, so that the design can facilitate the adjustment and extension between the first sleeve 2 and the second sleeve 5. When the first sleeve 2 and the second sleeve 5 are telescopically adjusted, the friction sleeve 15 will also be telescopic inside the telescopic cylinder 14. Since the friction between the friction sleeve 15 and the telescopic cylinder 14 is large, when the friction sleeve 15 stops moving, the inner wall of the telescopic cylinder 14 and the outer surface of the friction sleeve 15 are relatively stably fitted as a whole. Therefore, when the second sleeve 5 is adjusted, the position of the temperature measuring tube temperature measuring cylinder body 18 can also be extended and retracted, so that different gasifiers can be adapted through the temperature measuring tube temperature measuring cylinder body 18. The above is all the working principles of the utility model.
