They accurately measure the temperature at a specific location and transmit the temperature signal to monitoring equipment, providing critical data for production process control and safety assurance.

[0004] At present, the existing temperature sensor probes have some shortcomings: on the one hand, the installation structure of many probes is simple, relying only on threaded connections, which are prone to loosening under vibration or external force, affecting the measurement accuracy. On the other hand, traditional probes lack effective support and protection measures. The connection between the connecting wire and the probe is suspended for a long time, which can easily lead to breakage of the connection, making subsequent rewiring more troublesome and inconvenient. Therefore, a temperature sensor probe with a positioning structure is proposed to solve the above problems. Summary of the Invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment: a temperature sensor probe with a positioning structure, including a shell 1, an external thread is provided on the left surface of the shell 1, and a sensor probe is provided on the right side, and the whole can be fixed to the equipment through the external thread to perform temperature sensing. A connecting line 2 is provided on the left side of the shell 1. After the temperature is sensed by the sensor probe on the right side of the shell 1, the temperature signal is transmitted to the computer through the connecting line 2, so that the staff can intuitively monitor the temperature of the detection position in real time. A positioning component 4 is provided on the inner wall of the shell 1, and a supporting component 3 is provided on the left inner wall of the shell 1.

[0033] Reference Figure 2-Figure 4 The positioning assembly 4 includes a rotating disk 41, which is rotatably connected to the inner wall of the shell 1. The right inner wall of the shell 1 is provided with a cavity that fits the diameter of the rotating disk 41, so that the rotating disk 41 can only rotate on the right inner wall of the shell 1. The outer side wall of the rotating disk 41 is fixedly connected to a connecting block 42, and the connecting block 42 is slidably connected to the inner side wall of the shell 1. A cavity is provided on the right side of the shell 1, so that the connecting block 42 can slide up and down on the inner wall of the cavity, thereby driving the rotating disk 41 to rotate synchronously. One end of the limit spring 45 is fixedly connected to the inner wall of the connecting block 42, and the other end of the limit spring 45 is fixedly connected to the outer wall of the positioning block 46. The function of the limit spring 45 is to automatically reset the position of the positioning block 46 after the inclined surface of the triangular block 47 is pushed by the contact block 48 to drive the positioning block 46 to move, so that the triangular block 47 and the contact block 48 are synchronously restored to their initial positions.

[0034] Reference Figure 2-Figure 3 The positioning block 46 is slidably connected to the inner wall of the connecting block 42, and the inner wall of the connecting block 42 is provided with a cavity that fits the positioning block 46, so that the positioning block 46 can move on the inner wall of the connecting block 42, thereby disengaging from the through hole in the current position of the side wall of the shell 1, to facilitate the rotation of the rotating disk 41. The surface of the rotating disk 41 is provided with four groups of arc grooves, and the inner wall of the arc groove of the rotating disk 41 is slidably connected with a connecting rod 43. The inner wall of the shell 1 is provided with four groups of straight grooves, and the connecting rod 43 is slidably connected to the inner wall of the straight groove of the shell 1. Since the four groups of connecting rods 43 can only move up and down on the inner wall of the straight groove of the shell 1, at the same time, through the rotation of the rotating disk 41, the four groups of connecting rods 43 can be brought close to each other on the inner wall of the arc groove, thereby driving the four groups of connecting rods 43 to move close to or away from each other in the straight groove of the shell 1, so that the friction block 44 can contact the position of the threaded connection on the outer side of the shell 1, thereby increasing the stability of the overall threaded connection and positioning its position.

[0035] Reference Figure 2 and Figure 4The friction block 44 passes through and is slidably connected to the inner wall of the shell 1. The surface of the shell 1 is provided with four sets of empty grooves that fit the friction block 44. When the whole is installed to the equipment position, the friction block 44 moves to fit with the internal thread of the equipment, thereby positioning the shell 1, making the installation position more stable. The end of the connecting rod 43 away from the rotating disk 41 is fixedly connected to the friction block 44. The inner wall of the connecting block 42 is elastically connected to the positioning block 46 through the limit spring 45. The outer wall of the positioning block 46 is fixedly connected to the triangular block 47. The triangular block 47 is slidably connected to the inner wall of the connecting block 42. The inclined surface of the contact block 48 contacts the inclined surface of the triangular block 47. The contact between the two can be pushed by the movement of the contact block 48. The inclined surface of the triangular block 47 allows the triangular block 47 to drive the positioning block 46 to move outward synchronously, thereby disengaging the positioning block 46 from the insertion into the through hole at the current position of the side wall of the shell 1. The inner side wall of the shell 1 is provided with multiple groups of through holes, and the positioning block 46 is inserted into the inner wall of the through hole. The insertion between the two can fix the multiple positions of the synchronous movement of the connecting rod 43 and the friction block 44 driven by the rotation of the rotating disk 41, so that the position after being bitten with the external thread of the overall installed equipment can be fixed. The inner wall of the connecting block 42 is slidably connected to the contact block 48, and the inner wall of the connecting block 42 is provided with guide grooves that fit the upper and lower sides of the contact block 48, so that the contact block 48 can only move back and forth in a straight line on the inner wall of the connecting block 42 and cannot be separated from its inner wall.

[0036] Reference Figure 1 and Figure 2 The support assembly 3 includes a support cover 31, which is elastically connected to the left inner wall of the shell 1 through a return spring 32. One end of the return spring 32 is fixedly connected to the left inner wall of the shell 1, and the other end of the return spring 32 is fixedly connected to the outer side wall of the support cover 31. The function of the return spring 32 is to apply elastic support to the position of the support cover 31 to support the position of the connecting line 2 to prevent the connection between the connecting line 2 and the shell 1 from breaking. When the support cover 31 is moved to inspect the connecting line 2, the position of the support cover 31 after movement can be automatically reset. The support cover 31 is slidably connected to the left inner wall of the shell 1. A cavity is provided on the inner wall of the support cover 31, and the inner wall of the support cover 31 contacts the surface of the connecting line 2.

[0037] Working principle: When the temperature sensor probe is installed on the equipment, it is first initially fixed through the external thread on the left side of the shell 1, and then the contact block 48 is pushed. The movement of the contact block 48 pushes the inclined surface of the triangular block 47, so that the triangular block 47 drives the positioning block 46 to move outward, and the positioning block 46 is disengaged from the insertion of the through hole at the current position of the side wall of the shell 1. At this time, the connecting block 42 can be rotated, and the connecting block 42 drives the rotating disk 41 to rotate synchronously. Since the four groups of connecting rods 43 can only move up and down on the inner wall of the straight groove of the shell 1, and the rotation of the rotating disk 41 can make the four groups of connecting rods 43 move in the arc groove The inner walls move closer to or away from each other, thereby driving the four groups of connecting rods 43 to move in the straight groove of the shell 1, so that the friction block 44 fits with the internal thread of the equipment. When adjusted to the appropriate position, the contact block 48 is released, and the limit spring 45 automatically resets the position of the positioning block 46 after movement, so that the triangular block 47 and the contact block 48 are synchronously restored to the initial position, and the positioning block 46 is re-connected with the through hole of the inner side wall of the shell 1, and the rotation of the rotating disk 41 drives the connecting rod 43 and the friction block 44 to move synchronously to fix the position, thereby increasing the overall threaded connection stability and positioning the position of the shell 1.

[0038] During use, the support cover 31 of the support assembly 3 supports and protects the connecting line 2 through the reset spring 32 to prevent the connection between the connecting line 2 and the shell 1 from breaking. When the connecting line 2 needs to be inspected and repaired, the movable support cover 31 is operated. After the inspection is completed, the support cover 31 is automatically reset under the action of the reset spring 32. The entire device realizes the stable installation and positioning of the shell 1 and the protection function of the connecting line 2.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
