[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0025] See also Figure 1 - Figure 5 As shown, this embodiment provides a fixing device for a temperature sensor, including outdoor equipment 1, and further comprising:

[0026] The positioning frame 10 is fixedly connected to the outside of the outdoor device 1. The interior of the positioning frame 10 is provided with a mounting block 22. The exterior of the mounting block 22 is fixedly connected to the housing 2.

[0027] A fixing assembly is disposed inside the mounting block 22 and is used to fix the mounting block 22 and the positioning frame 10;

[0028] The disassembly assembly is symmetrically arranged outside the positioning frame 10 and is used to conveniently disassemble the mounting block 22 from the positioning frame 10;

[0029] The sensor body 6 is located inside the housing 2;

[0030] The abutment assembly is disposed on the upper surface of the housing 2 and is used to fix the sensor body 6 placed inside the housing 2 .

[0031] The above working principle: when it is necessary to fix the sensor body 6 and the outdoor equipment 1, it is only necessary to place the sensor body 6 inside the shell 2 first, and then fix the sensor body 6 inside the shell 2 through the interference component. After the sensor body 6 is fixed, the mounting block 22 and the positioning frame 10 are fixed and installed through the fixing component. At this time, the sensor body 6 can be fixed and installed between the outdoor equipment 1. When the sensor body 6 is damaged, the sensor body 6 can be easily removed from the inside of the shell 2 through the interference component, so that it is convenient for the staff to repair or replace the sensor body 6. When it is necessary to disassemble the mounting block 22 and the positioning frame 10, it is only necessary to disassemble the component to easily separate the mounting block 22 and the positioning frame 10, saving time and effort.

[0032] In order to conveniently fix the mounting block 22 and the positioning frame 10, the fixing assembly includes a support plate 23 fixedly connected to the inside of the mounting block 22, first telescopic rods 24 are symmetrically arranged on both sides of the outer wall of the support plate 23, and the telescopic ends of the plurality of first telescopic rods 24 are fixedly connected to the plug-in rods 25, and the outer sides of the plurality of first telescopic rods 24 are sleeved with reset springs 26, and the plurality of reset springs 26 are in contact between the plug-in rods 25 and the support plate 23. Guide grooves for the plug-in rods 25 to move are provided on both sides of the outer walls of the mounting block 22 and the positioning frame 10. When it is necessary to fix the mounting block 22 and the positioning frame 10, only the first telescopic rods 24 are symmetrically arranged on both sides of the outer wall of the support plate 23, and the first telescopic rods 24 are fixedly connected to the plug-in rods 25. First, press the plug-in rod 25, at this time, the plug-in rod 25 will simultaneously squeeze the first telescopic rod 24 and the reset spring 26, and then plug the mounting block 22 into the interior of the positioning frame 10. At this time, the mounting block 22 will drive the plug-in rod 25 to move synchronously. When the mounting block 22 drives the plug-in rod 25 to move into the guide grooves on both sides of the outer wall of the positioning frame 10, the reset spring 26 is reset, driving the plug-in rod 25 to move synchronously. When the plug-in rod 25 is plugged into the guide grooves on both sides of the outer wall of the positioning frame 10, the mounting block 22 can be fixed to the positioning frame 10, and the shell 2 and the outdoor equipment 1 can be fixedly installed.

[0033] Considering that when the sensor body 6 is not needed to be used, the mounting block 22 needs to be disassembled from the positioning frame 10, the disassembly assembly includes a fixing plate 11 symmetrically arranged on the upper and lower surfaces of the positioning frame 10, and the outer parts of the plurality of fixing plates 11 are fixedly connected with the second telescopic rod 12, and the telescopic ends of each of the two second telescopic rods 12 are fixedly connected with the pressing plate 5, and the outer parts of the plurality of second telescopic rods 12 are sleeved with a resistance spring 13, and the plurality of resistance springs 13 are in resistance between the pressing plate 5 and the fixing plate 11, and the opposite sides of the two pressing plates 5 are symmetrically provided with an extrusion rod 15. When the mounting block 22 needs to be disassembled from the positioning frame 10, only the fixing plate 11 is fixedly connected with the second telescopic rod 12, and the pressing plate 5 is fixedly connected with the second telescopic rod 12. The pressing plate 5 needs to be pressed, and at this time the pressing plate 5 will drive the extrusion rod 15 to move synchronously. When the extrusion rod 15 squeezes the plug-in rod 25 into the interior of the positioning frame 10, the shell 2 is pulled. At this time, the shell 2 will drive the mounting block 22 to move synchronously. When the mounting block 22 is detached from the interior of the positioning frame 10, the mounting block 22 and the positioning frame 10 can be disassembled. During the movement of the pressing plate 5, the second telescopic rod 12 and the resistance spring 13 will also be squeezed synchronously. When the disassembly between the mounting block 22 and the positioning frame 10 is completed, the pressing plate 5 is released. At this time, the resistance spring 13 is reset, which can drive the pressing plate 5 to reset and move synchronously.

[0034] In order to effectively protect the second telescopic rod 12 and the resistance spring 13 from dust, the exteriors of the plurality of second telescopic rods 12 are each provided with an accordion dust cover 14, and the two ends of the plurality of accordion dust covers 14 are respectively fixedly connected to the pressing plate 5 and the opposite side of the fixing plate 11. The accordion dust cover 14 can effectively protect the second telescopic rod 12 and the resistance spring 13 from dust, thereby effectively extending the service life of the second telescopic rod 12 and the resistance spring 13, and at the same time will not cause any influence on the normal use effect of the second telescopic rod 12 and the resistance spring 13.

[0035] In order to effectively fix the sensor body 6 placed inside the shell 2, the interference component includes an adjustment plate 4 fixedly connected to the upper surface of the shell 2, the inner bottom end of the adjustment plate 4 is rotatably connected to a rotating rod 17, the top end of the rotating rod 17 extends to the outside of the adjustment plate 4 and is fixedly connected to a knob 16, the inner bottom end of the shell 2 is symmetrically rotatably connected to a threaded rod 18, the top ends of the two threaded rods 18 extend to the inside of the adjustment plate 4 and are rotatably connected to the inner top end of the adjustment plate 4, the two threaded rods 18 and the rotating rod 17 are connected to the driving wheel through a belt 19, the outer sides of the two threaded rods 18 are threadedly connected to threaded blocks 20, a lower pressure plate 21 is fixedly connected between the two threaded blocks 20, and the bottom of the lower pressure plate 21 and the inner bottom end of the shell 2 are bonded with protective Pad, when it is necessary to fix the sensor body 6 placed inside the shell 2, it is only necessary to turn the knob 16. At this time, the knob 16 will drive the rotating rod 17 to rotate synchronously. Since the two threaded rods 18 and the rotating rod 17 are connected by the belt 19 and the driving wheel for transmission, the two threaded rods 18 will rotate synchronously at this time, and the threaded block 20 will move synchronously on the outside of the threaded rod 18, driving the lower pressure plate 21 to move synchronously. When the bottom of the lower pressure plate 21 conflicts with the upper surface of the sensor body 6, the sensor body 6 can be effectively fixed. Since the sizes of the driving wheels used between the two threaded rods 18 and the rotating rod 17 are inconsistent, it will not cause any influence on the transmission relationship between the threaded rod 18 and the rotating rod 17.

[0036] In addition, in order to effectively close the shell 2, a visible closing door 3 is hinged on the outside of the shell 2. An L-shaped plate 7 is symmetrically arranged on the upper surface of the visible closing door 3. A snap-in plate 27 is symmetrically arranged on the upper surface of the shell 2. The two snap-in plates 27 are each provided with a movable groove for the L-shaped plate 7 to move. The front end surface and the rear end surface of the shell 2 are both fixedly connected with a connecting rope 8. The other ends of the two connecting ropes 8 are both fixedly connected with a fixing pin 9. The two snap-in plates 27 and the L-shaped plate 7 are fixedly connected by the fixing pin 9. When the shell 2 needs to be closed, it is only necessary to lift the visible closing door 3. At this time, the visible closing door 3 will drive the L-shaped plate 7 to move synchronously. When the L-shaped plate 7 is inserted into the movable groove inside the snap-in plate 27, the snap-in plate 27 and the L-shaped plate 7 are fixed by the fixing pin 9. At this time, the shell 2 can be closed by the visible closing door 3, so that the sensor body 6 inside the shell 2 can be effectively protected.
