DETAILED DESCRIPTION

[0032] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0033] REFERENCE Figures 1-2The utility model provides an embodiment: infrared inductor convenient to dismount, including base 1, the bottom surface of base 1 is equipped with the slot 2, the inside insertion of slot 2 is equipped with sensor body 3, the outside of sensor body 3 is equipped with the heat dissipation mouth, is helpful to the heat dissipation processing inside sensor body 3, sensor body 3 can be in the inside linear motion of slot 2 in the up and down direction, and can rotate.

[0034] Refer to Figures 3-5 The upper side of the outer surface of the sensor body 3 is fixedly connected with a fixed plate 4, and the fixed plate 4 can be driven to move synchronously when the sensor body 3 moves. A jack 5 is formed in the upper surface of the left side of the fixed plate 4. When the limiting rod 72 is connected into the jack 5, the fixed plate 4 and the sensor body 3 can be connected and fixed synchronously, so that the sensor body 3 remains stable during use. A vertical groove 6 is formed in the inner wall surface of the slot 2, and a limiting cavity 7 is formed in the upper surface of the slot 2. The size of the fixed plate 4 is adapted to the size of the vertical groove 6. When the fixed plate 4 is moved upward and aligned with the vertical groove 6, the vertical groove 6 can guide and limit the movement of the sensor body 3 and the fixed plate 4, so that they move linearly in the up and down direction. The outer wall of the fixed plate 4 is in close contact with the inner wall of the limiting cavity 7. When the fixed plate 4 is moved upward and away from the inside of the vertical groove 6 and enters the inside of the limiting cavity 7, the sensor body 3 can be rotated to drive the fixed plate 4 to rotate away from the vertical groove 6. At this time, the limiting cavity 7 can preliminarily limit the whole composed of the fixed plate 4 and the sensor body 3, so as to avoid damage caused by the sensor body 3 falling downward.

[0035] A limiting unit is arranged at the bottom of the limiting cavity 7. The limiting unit comprises a groove 71 formed in the bottom surface of the base 1. A limiting rod 72 is arranged in the inside of the groove 71. The upper end of the limiting rod 72 penetrates the base 1. The inner wall of the base 1 can guide and limit the movement of the limiting rod 72, so that the limiting rod 72 can only move linearly in the up and down direction without being separated from the base 1. The upper end of the limiting rod 72 is connected with the inside of the jack 5. When the limiting rod 72 enters the inside of the jack 5, the fixed plate 4 and the sensor body 3 can be connected and fixed. A spring 73 is sleeved on the outside of the limiting rod 72. A circular plate 74 is fixedly connected to the bottom end of the limiting rod 72. When the circular plate 74 moves, it can drive the limiting rod 72 to move synchronously. The upper end of the spring 73 is fixedly connected with the inside top surface of the groove 71, and the bottom end of the spring 73 is fixedly connected with the upper surface of the circular plate 74.

[0036] When the circular plate 74 is forced to move downward, the spring 73 can be pulled, so that the spring 73 is stretched to generate elastic potential energy. When the fixed plate 4 enters the limiting cavity 7, the circular plate 74 can be pulled downward to drive the limiting rod 72 to move downward, and the spring 73 is pulled to generate elastic potential energy, so that the upper end of the limiting rod 72 is away from the inside of the limiting cavity 7, avoiding hindering the rotation of the fixed plate 4. When the fixed plate 4 is rotated to align the jack 5 with the limiting rod 72, the circular plate 74 can be released, so that the limiting rod 72 moves upward under the action of the elastic potential energy of the spring 73, and is clamped into the inside of the jack 5, clamping and fixing the fixed plate 4 and the sensor body 3, so that the sensor body 3 remains stable during use.

[0037] The bottom surface of the base 1 is fixedly connected with an L-shaped fixing frame 8 on the left side. The right end of the L-shaped fixing frame 8 is located directly below the circular plate 74, which can limit the movement of the circular plate 74 and avoid excessive downward movement of the circular plate 74, which can cause the spring 73 to be stretched beyond its limit and damaged.

[0038] Referring to Figure 3 and Figure 6 , the inside bottom surface of the limiting cavity 7 is fixedly connected with a dismounting limiting plate 9. When the fixed plate 4 moves inside the limiting cavity 7 to abut the left surface of the dismounting limiting plate 9, the fixed plate 4 is aligned with the vertical groove 6, and the sensor body 3 can be directly removed downward at this time. The inside bottom surface of the limiting cavity 7 is fixedly connected with a mounting limiting plate 10. When the fixed plate 4 rotates inside the limiting cavity 7 to abut the mounting limiting plate 10, the jack 5 is aligned with the limiting rod 72, and the clamping and fixing can be quickly completed, reducing the operation difficulty. The inside top surface of the limiting cavity 7 is rotatably connected with a rotating plate 11. The bottom surface of the rotating plate 11 is fixedly connected with a rubber pad. The bottom surface of the rubber pad abuts the upper surface of the sensor body 3. When the sensor body 3 drives the fixed plate 4 to move upward into the limiting cavity 7, the rubber pad is extruded. At this time, the rubber pad can fill the gap between the upper surface of the fixed plate 4 and the inside top surface of the limiting cavity 7, avoiding the vibration of the sensor body 3 during use, affecting the use effect. At the same time, when the sensor body 3 rotates to adjust the position of the fixed plate 4, the rubber pad can rotate with the fixed plate 4 under the action of the rotating plate 11, avoiding hindering the movement of the sensor body 3.

[0039] Working principle: when installing the sensor body 3, the fixed plate 4 is inserted into the vertical slot 6, so that the sensor body 3 drives the fixed plate 4 to move up into the limiting cavity 7, then the sensor body 3 is rotated slightly to drive the fixed plate 4 to leave the vertical slot 6, then the round plate 74 is pulled down to drive the limiting rod 72 to move down out of the inside of the limiting cavity 7, at this time the sensor body 3 can be continuously rotated to drive the fixed plate 4 to be attached to the installation limiting plate 10, so that the limiting rod 72 is quickly aligned with the insertion hole 5, then the round plate 74 can be loosened, so that the limiting rod 72 moves up under the elastic potential energy of the spring 73, is clamped into the inside of the insertion hole 5, quickly clamps and fixes the fixed plate 4 and the sensor body 3, so that the sensor body 3 remains stable during use, when the sensor body 3 needs to be disassembled and repaired, the round plate 74 can be pulled down to drive the limiting rod 72 to move down out of the inside of the insertion hole 5, to release the clamping and fixing of the fixed plate 4 and the sensor body 3, at this time under the limiting of the limiting cavity 7 inner wall, the fixed plate 4 and the sensor body 3 cannot directly fall down to cause damage, then the sensor body 3 is rotated to the position where the fixed plate 4 is aligned with the vertical slot 6, so that the sensor body 3 can directly move down to complete disassembly, the operation is simple and convenient.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. in the spirit and principles of the utility model, should be contained in the protection scope of the utility model.
