DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present embodiment provides a kind of clamping equipment for thermocouple, including ring sleeve 1 and the inner hole 11 formed in the middle of ring sleeve 1, the thermocouple 3 is inserted in the ring sleeve 1, the connecting sleeve 4 is fixedly installed on the surface of the thermocouple 3, a plurality of gear rings 5 are arranged on the circumferential surface of the connecting sleeve 4, at least one through slot 12 is formed in the circumferential surface of the ring sleeve 1, the through slot 12 is communicated with the inner hole 11 of the ring sleeve 1, the clamping block 13 is arranged in the through slot 12 and slides along the radial direction of the ring sleeve 1, the clamping strip 14 that cooperates with the gear ring 5 is fixedly installed on the side of the clamping block 13 close to the thermocouple 3, and the positioning member 6 for inserting the clamping strip 14 into adjacent gear ring 5 is arranged on the ring sleeve 1.

[0025] The clamping equipment for thermocouple 3 can effectively fix the thermocouple 3 by the cooperation between the ring sleeve 1 and the thermocouple 3, and prevent the displacement of the thermocouple 3 during measurement. The clamping mechanism is mainly arranged on the outside of the temperature measuring equipment, that is, the ring sleeve 1 is fixed on the outside of the temperature measuring equipment, and the thermocouple head is inserted into the temperature measuring equipment to measure the temperature. Specifically, the plurality of gear rings 5 arranged on the circumferential surface of the connecting sleeve 4 on the surface of the thermocouple 3 cooperate with the clamping block 13 and the clamping strip 14 arranged in the through slot 12 of the ring sleeve 1 and slide along the radial direction, when the clamping strip 14 is inserted into adjacent gear ring 5 through the positioning member 6, the thermocouple 3 can be fastened, and the thermocouple 3 will not loosen due to vibration or external force during operation, thereby ensuring the accuracy and stability of measurement. The clamping strip 14 is inserted into different gear rings 5, which can adjust the position of the thermocouple 3, and facilitate the detection of temperature in different areas.

[0026] Please refer toFigures 4-6 The positioning member 6 comprises a pressing plate 61 moving axially along the ring sleeve 1, the ring sleeve 1 is provided with a through hole 62 for the pressing plate 61 to pass through, the through hole 62 is communicated with the through groove 12, and the clamping block 13 is provided with an inclined surface 63 and a vertical surface 64 away from the thermocouple 3. When the clamping strip 14 is separated from the gear ring 5, the pressing plate 61 is located on the upper side of the inclined surface 63 or in contact with the inclined surface 63. When the clamping strip 14 is in contact with the gear ring 5, the pressing plate 61 is in abutment with the vertical surface 64.

[0027] In the initial state, the pressing plate 61 is located on the upper side of the inclined surface 63 of the clamping block 13 or in contact with the inclined surface 63, at this time, the thermocouple 3 can move relative to the ring sleeve 1, and the clamping strip 14 is not in contact with the gear ring 5. After moving the thermocouple 3 to the required position, the pressing plate 61 is moved to the direction of the clamping block 13, and the pressing plate 61 will move along the inclined surface 63 to the vertical surface 64. In this process, the clamping block 13 will move to the direction of the thermocouple 3 until the clamping strip 14 on the clamping block 13 is embedded between the gear ring 5, realizing the fixed positioning of the thermocouple 3, thereby achieving the effects of convenient installation and safe fixation.

[0028] In order to facilitate the rebound of the clamping block 13 and facilitate the automatic disengagement of the clamping strip 14 from the gear ring 5 when the pressing plate 61 is pulled out, a spring 15 for driving the clamping block 13 away from the thermocouple 3 is further arranged, and the spring 15 is fixedly installed between the inner wall of the through groove 12 and the clamping block 13. When the clamping block 13 is pushed by the pressing plate 61 to move to the direction of the thermocouple 3, the spring 15 is stretched and the internal elastic potential energy is accumulated. When the pressing plate 61 is pulled out, under the elastic force of the spring 15, the clamping block 13 will move away from the thermocouple 3, that is, shrink into the through groove 12.

[0029] Please refer to Figure 5 and Figure 6 The clamping block 13 is provided with a through hole 16, and a guide rod 17 is slidably arranged in the through hole 16, and the guide rod 17 is fixedly connected with the inner wall of the through groove 12. Through the guide rod 17, the clamping block 13 is guided, thereby facilitating the sliding of the clamping block 13 in the through groove 12 and keeping stable.

[0030] The guide rod 17 is located in the spring 15. The spring 15 has a one-way rod inside, so that when the spring 15 is bent, the guide rod 17 can play a limiting role, reducing the bending arc of the spring 15.

[0031] The clamping strip 14 is arc-shaped, and the diameter of the virtual circle formed is the same as the diameter of the gear ring 5. Thus, after the clamping strip 14 is embedded in the gear ring 5, the contact area is increased and the stress is uniform.

[0032] The side of the clamping block 13 close to the thermocouple 3 is an arc surface. It is convenient to fit with the clamping strip 14, improve the connection area of the clamping block 13 and the clamping strip 14, disperse the stress, and not easy to be damaged.

[0033] The through slot 12 has two, opposite to the two sides of the thermocouple 3. Thus the thermocouple 3 both sides exist card strip 14 card joint, stress uniform, each component stress deformation is small.

[0034] Two said pressing plate 61 upside common fixed installation snap ring 7, the snap ring 7 and the ring sleeve 1 coaxial, the snap ring 7 outer diameter is greater than the ring sleeve 1 outer diameter.

[0035] When the need to move the pressing plate 61 along the ring sleeve 1 axial, through artificial pull the snap ring 7, through the snap ring 7 outer diameter is greater than the ring sleeve 1 outer diameter, easy to get.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 4 , the ring sleeve 1 inside is provided with arc hole 18 for the pressing plate 61 sliding, the arc hole 18 and the through hole 62 are communicated, the ring sleeve 1 is fixedly installed with first magnet 19 near the snap ring 7 side, the snap ring 7 is fixedly installed with second magnet 71 near the ring sleeve 1 side, the first magnet 19 and the second magnet 71 opposite face magnetic pole is different, when the snap ring 7 and the ring sleeve 1 contact and the pressing plate 61 is located in the through hole 62, the first magnetic strip and the second magnetic strip are misaligned, when the snap ring 7 and the ring sleeve 1 contact and the pressing plate 61 is located in the arc hole 18, the first magnet 19 and the second magnet 71 contact.

[0037] When the snap ring 7 and the ring sleeve 1 contact, if the pressing strip is located in the through hole 62, then the first magnet 19 and the second magnet 71 will be in misaligned state, the opposite face of the first magnet 19 and the second magnet 71 is not opposite, so that the mutual magnetic attraction force is weak, which is convenient for manual operation to drive the snap ring 7 to move along the ring sleeve 1 axial; but if the pressing plate 61 and the vertical surface 64 of the clamping block 13 contact and slide to the arc hole 18, the first magnet 19 and the second magnet 71 will contact each other, the opposite face is close together, at this time the magnetic force generated by the lock is the largest, so that the snap ring 7 and the ring sleeve 1 are more firmly fixed together, and then the snap ring 7 is difficult to separate from the ring sleeve 1, so that the thermocouple 3 is clamped by the ring sleeve 1 and is difficult to separate. If the snap ring 7 and the ring sleeve 1 need to be separated, first rotate the snap ring 7, so that the snap ring 7 and the ring sleeve 1 rotate relative to each other, at this time the opposite face of the first magnet 19 and the second magnet 71 is separated, so that the mutual magnetic attraction force of the first magnet 19 and the second magnet 71 is greatly reduced, which is convenient for the separation of the snap ring 7 and the ring sleeve 1. This design cleverly uses the magnetic attraction force of the magnet and the position change of the card strip 14 in different holes, realizes the flexible installation and stable fixation of the snap ring 7 and the ring sleeve 1, enhances the reliability of the overall structure, and effectively reduces the separation of the pressing plate 61 and the clamping block.

[0038] Please refer to Figure 3 and Figure 4Wherein is further to strengthen the anti-drop performance of the thermocouple 3 and the ring 1. The ring 1 is internally provided with a clamping groove 20 on the side away from the through hole 62, and the side of the pressing plate 61 is fixedly provided with a limiting block 65 for inserting into the clamping groove 20.

[0039] When the pressing plate 61 slides into the arc-shaped hole 18, the first magnet 19 and the second magnet 71 are in contact with each other, and the limiting block 65 is inserted into the clamping groove 20, so that the pressing plate 61 cannot move axially along the ring 1, and the first magnet 19 and the second magnet 71 are difficult to separate along the axis of the ring 1, thereby strengthening the connection strength of the first magnet 19 and the second magnet 71, that is, improving the anti-drop performance of the thermocouple 3.

[0040] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims.
