[0027] The utility model provides Figure 1 The threaded temperature sensor anti-loosening structure shown includes a temperature sensor body 1, and also includes:

[0028] The fixing mechanism 2 is arranged on the outside of the temperature sensor body 1 and is used for installing and adjusting the temperature sensor body 1 .

[0029] In order to keep the temperature sensor body 1 stable after installation, Figure 1-2 and Figure 4-5 As shown, the fixing mechanism 2 includes a mounting plate 201, which is movably sleeved on the outside of the temperature sensor body 1, and a threaded sleeve 202 is fixedly installed on the outer wall of one end of the mounting plate 201. Adjusting screws 204 are arranged around the inner wall of one end of the mounting plate 201 close to the threaded sleeve 202, and clamping plates 206 are arranged on the outer sides of the four adjusting screws 204. The external thread of the threaded sleeve 202 is connected to the internal thread of the mounting part, so that the temperature sensor body 1 can be installed in a suitable position. The adjusting screw 204 is rotated so that the clamping plate 206 can clamp the outer wall of the mounting part, thereby reinforcing the installed temperature sensor body 1 and preventing the threaded sleeve 202 from loosening.

[0030] In order to conveniently adjust the length of the temperature sensor body 1 that penetrates into the device, as Figure 1-5 As shown, a fixing bracket 207 is fixedly installed on the outer wall of the other end of the mounting plate 201, and an adjusting screw 209 for adjusting the temperature sensor body 1 is arranged on the top of the inner wall of the fixing bracket 207, and an adjusting knob 210 is fixedly installed on the end of the adjusting screw 209 away from the mounting plate 201. The rotation of the adjusting knob 210 can drive the adjusting screw 209 to rotate, and further drive the temperature sensor body 1 to move inside the fixing bracket 207, so as to adjust its length penetrating into the interior of the device.

[0031] In order to conveniently adjust the length of the detection probe 101 inside the device, Figure 1-5 As shown, the temperature sensor body 1 includes a detection probe 101, one end of which is fixedly installed with a transmission line 102, and a movable seat 103 is fixedly installed on the top and bottom of the outer wall of the end of the detection probe 101 close to the transmission line 102. The top and bottom of the inner wall of the fixed frame 207 are provided with mounting grooves 208, and the inner walls of the two mounting grooves 208 are respectively movably connected with the outer walls of the two movable seats 103. The inner wall of the top mounting groove 208 is rotatably connected with the adjusting screw rod 209, and the inner wall of the bottom mounting groove 208 is fixedly installed with a limiting rod 211. The outer wall of the adjusting screw rod 209 is threadedly connected with the inner wall of the adjacent movable seat 103, and the outer wall of the limiting rod 211 is movably connected with the inner wall of the adjacent movable seat 103. The rotation of the adjusting screw rod 209 can drive the adjacent movable seat 103 to move, and then the length of the detection probe 101 extending into the device can be adjusted. At the same time, the mounting groove 208 and the limiting rod 211 can limit the movement of the movable seat 103, so that the detection probe 101 remains stable during the adjustment process.

[0032] In order to keep the clamping plate 206 stable during the adjustment process, Figure 2 and Figure 4 As shown, four movable grooves 203 are opened in an annular shape at equal intervals on the inner wall of one end of the mounting plate 201 close to the threaded sleeve 202, and the inner walls of the four movable grooves 203 are rotatably connected to four adjusting screws 204 respectively. Four clamping plates 206 are fixedly installed with sliders 205 on one end close to the mounting plate 201, and the inner walls of the four sliders 205 are respectively threadedly connected to the outer walls of the four adjusting screws 204, and the outer walls of the four sliders 205 are respectively movably connected to the inner walls of the four movable grooves 203, and the movable grooves 203 can limit the movement of adjacent sliders 205, thereby allowing the clamping plate 206 to remain stable during the movement.

[0033] In order to ensure that the clamping plate 206 can stably clamp the outer wall of the installation part, Figure 2 and Figure 4-5As shown, the left-view vertical section of the clamping plate 206 is set as a fan-shaped structure, and the front-view vertical section of the clamping plate 206 is set as an L-shaped structure. Through the clamping connection between the clamping plate 206 and the outer wall of the installation part, loosening of the connection between the threaded sleeve 202 and the installation part can be avoided, thereby ensuring the stability of the temperature sensor body 1 during operation.

[0034] When installing and fixing the temperature sensor body 1, the temperature sensor body 1 can be installed on the device through the threaded connection between the threaded sleeve 202 and the inner wall of the installation part, and then the adjacent sliders 205 are moved along the inner wall of the movable groove 203 on the outside thereof by rotating the four adjusting screws 204, so that the four clamping plates 206 can clamp and fix the outer wall of the installation part, so that the connection between the threaded sleeve 202 and the installation part can be reinforced, and the threaded sleeve 202 can be prevented from loosening. At the same time, the adjusting screw 209 is rotated by rotating the adjusting knob 210, so that one of the movable seats can be driven 103 moves on its outer side along the inner wall of one of the mounting grooves 208, thereby driving the detection probe 101 to move along the inner side of the fixing frame 207, thereby adjusting the length of the detection probe 101 inside the device. At the same time, the limiting rod 211 and the inner wall of another mounting groove 208 can limit the movement of the other movable seat 103, so that the detection probe 101 remains stable during the adjustment process, so that the detection probe 101 can stably detect the temperature inside the device. This embodiment specifically solves the problem in the prior art that the temperature sensor is prone to loosening after installation and its length inside the device cannot be adjusted, which affects the detection result.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
