[0020] 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.

[0021] See also Figure 1 to Figure 3 In an embodiment of the utility model, an impact-resistant water temperature sensor comprises a water temperature sensor 1, the outer wall of the water temperature sensor 1 is formed with a threaded connector 2, and the outer wall of the water temperature sensor 1 is formed with a No. 1 hexagonal block 3 at the top of the threaded connector 2, the outer wall of the head of the water temperature sensor 1 is formed with a No. 2 hexagonal block 4, and one end of the No. 2 hexagonal block 4 is formed with a fixed head 5, the fixed head 5 is a hollow structure with openings at both ends, and the inner wall of the fixed head 5 is plugged with an electric plug 7, and the electric plug 7 fully inserted into the inner wall of the fixed head 5 is electrically connected to the circuit board in the head of the water temperature sensor 1 through the No. 2 hexagonal block 4; the outer wall of the fixed head 5 is connected with an anti-slip mechanism, and the anti-slip mechanism is used to press the electric plug 7 to prevent the electric plug 7 from loosening and breaking; the anti-slip mechanism and the No. 2 hexagonal block 4 are distributed with anti-rotation mechanisms, and the anti-rotation mechanisms are used to limit the position of the anti-slip mechanism to prevent the anti-slip mechanism from rotating.

[0022] In this embodiment: first, the water temperature sensor 1 is installed at the corresponding pipe position. The pipe should have a connecting sleeve that matches the threaded connector 2. The sensing end of the water temperature sensor 1 is passed through the connecting sleeve and enters the pipe. Then, it is docked with the No. 1 hexagonal block 3 by using a tool (such as a wrench). Then, the No. 1 hexagonal block 3 is driven to rotate by the tool, and then the threaded connector 2 is driven to rotate and threadedly connected with the connecting sleeve 1. A rubber sealing ring should be provided at the contact position between the connecting sleeve and the threaded connector 2 to ensure the sealing of the connection and prevent water leakage.

[0023] After the water temperature sensor 1 is installed, the electric plug 7 is fixed by the anti-slip mechanism, and then the position of the anti-slip mechanism is limited by the anti-rotation mechanism to prevent the anti-slip mechanism from self-rotating under impact vibration and causing loosening.

[0024] Please refer to Figure 1 and Figure 2 The anti-slip mechanism includes a rotating head 8 threadedly connected to the outer wall of the fixed head 5. The end of the rotating head 8 close to the fixed head 5 is an open structure, and the inner wall of the opening is formed with an internal thread, and the outer wall of the fixed head 5 is formed with an external thread; the outer wall of the rotating head 8 is integrally formed with a No. 3 hexagonal block 9.

[0025] In this embodiment: first, the electric plug 7 is fully inserted to form an effective connection with the wiring terminal part of the circuit board, and then the inner wall of the rotating head 8 is docked with the outer wall of the fixed head 5. After docking, the rotating head 8 is rotated to form an effective threaded connection with the fixed head 5. At this time, the rotating head 8 forms an effective limit for the electric plug 7 in the inserted state, preventing the electric plug 7 from loosening and disconnecting due to impact vibration.

[0026] Please refer to Figure 2 One end of the electric plug 7 is connected to a connecting wire 10, and the connecting wire 10 passes through the rotating head 8. The other end of the rotating head 8 is provided with a round hole for the connecting wire 10 to pass through.

[0027] In this embodiment, when the rotating head 8 rotates, the rotating head 8 will not drive the connecting wire 10 and the electric plug 7 to rotate.

[0028] Please refer to Figure 3 The anti-rotation mechanism includes an anti-rotation plate 6 integrally formed on the outer wall of the No. 3 hexagonal block 9 and the No. 2 hexagonal block 4. A plug-in hole 11 is provided inside the anti-rotation plate 6. A plug-in column 13 is slidably connected to the inner wall of the plug-in hole 11. A baffle 12 is formed at one end of the plug-in column 13, and a check plate 15 is formed at the other end of the plug-in column 13. Receiving grooves 14 for accommodating the squeezed check plate 15 are provided on the upper and lower end surfaces of the plug-in column 13. The horizontal plate portion and the inclined portion of the check plate 15 form a "V"-shaped structure.

[0029] In this embodiment: after the anti-slipping mechanism is tightened, since the sizes of the internal thread and the external thread are fixed, the two groups of anti-rotation plates 6 distributed on the No. 3 hexagonal block 9 and the No. 2 hexagonal block 4 are aligned. At this time, the non-return plate 15 is inserted into the plug-in hole 11. When the inclined portion of the non-return plate 15 contacts the plug-in hole 11, the reaction force generated causes the inclined portion to deform and enter the accommodating groove 14. Then, the baffle 12 is continuously applied with thrust until the plug-in column 13 is fully inserted into the two aligned plug-in holes 11. At this time, the inclined portion of the non-return plate 15 is separated from the plug-in hole 11. The inclined portion of the non-return plate 15 is made of elastic plastic. The inclined portion of the non-return plate 15 that has lost its limit is reset and opened, pressing against the side of the other group of anti-rotation plates 6, thereby limiting the rotation of the anti-slipping mechanism caused by impact vibration.

[0030] Please refer to Figure 3 The outer wall of the plug-in column 13 coincides with the inner wall of the plug-in hole 11 , and the length of the plug-in column 13 is equal to the total width of the two anti-rotation plates 6 .

[0031] In this embodiment, after the plug-in posts 13 are fully plugged into the two aligned plug-in holes 11 , the two sets of anti-rotation plates 6 are effectively restricted and cannot rotate.

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
