Technical Field

[0001] The invention relates to the technical field of sensors, in particular to a sensor with a PID control function. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. At the same time, the sensor can also be controlled by PID.

[0003] The current PID sensor has the following inconveniences:

[0004] Sensors are generally connected to devices using pins, and the pins are directly inserted into the device. However, after the sensor is connected, it is generally difficult to remove it. If it needs to be removed, people will forcibly unplug it, which is likely to cause the sensor to bend or break, making the sensor unusable. In addition, the outside of the sensor is generally unprotected, and when external moisture or dust enters, it is very easy to cause damage to the sensor, making the sensor unable to work normally. Summary of the invention

[0005] The object of the present invention is to provide a sensor with PID control function to solve the related problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a sensor body, a connecting plate is provided at the bottom of the outer side of the sensor body, a protective shell is provided on the top of the connecting plate, connecting rods are provided on both sides of the protective shell, a ring rod is provided on one side of the connecting rod, a mounting ring is provided between one side of two groups of the connecting rods, a guide plate is provided at the bottom of the mounting ring, a protective assembly is provided on the top of the protective shell, sliding rods are symmetrically provided on both sides of the bottom of the connecting plate, push rings are provided at the bottom of the two groups of the sliding rods, and a moving rod is provided on the top of the sliding rod.

The protective cover A13 is located on one side of the top of the protective shell 9, and the protective cover B14 is provided on the other side of the top of the protective shell 9. The two ends of one side of the protective cover A13 are symmetrically provided with plugs 20, and the two ends of one side of the protective cover B14 are symmetrically provided with slots 19, and the slots 19 and the plugs 20 are adapted to each other.

[0029] As a preferred solution of this embodiment: A connection groove 6 is provided inside the connecting plate 8, and the bottom sides of both sides of the sensor body 1 are symmetrically provided with sliders 15, and the sliders 15 are adapted to the through grooves 16. The two ends of the top of the connecting plate 8 are symmetrically provided with through grooves 16, which facilitates the subsequent disassembly of the sensor body 1.

[0030] As a preferred solution of this embodiment: The bottom sides of the inner sides of the protective cover A13 and the protective cover B14 are both provided with inclined plane guiding blocks, and one side of the top of the moving rod 2 is provided with an inclined plane groove to guide the protective cover A13 and the protective cover B14.

[0031] As a preferred solution of this embodiment: A groove is provided at the bottom of one side of the moving rod 2, and the groove is adapted to the guide plate 17, and the moving rod 2 can be driven to displace when the guide plate 17 rotates.

[0032] As a preferred solution of this embodiment: The two sides of the protective shell 9 are symmetrically provided with sliding grooves, and the connecting rod 3 is adapted to the sliding grooves, which facilitates the movement of the connecting rod 3.

[0033] As a preferred solution of this embodiment: Both the limit groove 11 and the limit block 12 are of T-shaped structures, and the limit groove 11 and the limit block 12 are adapted to each other to improve the limit effect.

[0034] As a preferred solution of this embodiment: The sensor body 1 is provided with a mounting plate, and a plurality of groups of ventilation holes 18 are evenly provided on the top of the mounting plate to improve the heat dissipation effect of the sensor body 1.

[0035] As a preferred solution of this embodiment: The guide plate 17 is composed of an arc-shaped inclined plane, and the number of the guide plates 17 is two groups, which facilitates guiding.

[0036] Example 1, as Figures 1-3As shown, when disassembling the sensor body 1, first hold the annular rod 4 and rotate it. Then, the annular rod 4 drives the connecting rod 3 and the mounting ring 10 to rotate. Under the guiding action of the guide plate 17, the moving rod 2 is extruded. At this time, the moving rod 2 drives the sliding rod 5 and the pushing ring 7 to move downward. Since the connecting plate 8 is connected to the sensor body 1 and the connecting plate 8 is in a fixed state, when the pushing ring 7 moves downward, it drives the connecting plate 8 and the sensor body 1 to move upward in a straight line, thereby pulling out the sensor body 1.

[0037] Embodiment 2, as Figures 1-4 shown, when the moving rod 2 descends, one side of the moving rod 2 gradually extrudes the protective cover A13 and the protective cover B14, so that the plug 20 assembly disengages from the slot 19 and drives the protective cover A13 and the protective cover B14 to separate. Then, the protective cover A13 and the protective cover B14 drive the limiting block 12 to slide along the limiting groove 11. Thus, when the sensor body 1 is pulled out, the protective cover A13 and the protective cover B14 are automatically opened, facilitating the removal of the sensor body 1.

[0038] Working principle: When disassembling the sensor body 1, first hold the annular rod 4 and rotate it. Then, the annular rod 4 drives the connecting rod 3 and the mounting ring 10 to rotate. Under the guiding action of the guide plate 17, the moving rod 2 is extruded. At this time, the moving rod 2 drives the sliding rod 5 and the pushing ring 7 to move downward. Since the connecting plate 8 is connected to the sensor body 1 and the connecting plate 8 is in a fixed state, when the pushing ring 7 moves downward, it drives the connecting plate 8 and the sensor body 1 to move upward in a straight line, thereby pulling out the sensor body 1;

[0039] When the moving rod 2 descends, one side of the moving rod 2 gradually extrudes the protective cover A13 and the protective cover B14, so that the plug 20 assembly disengages from the slot 19 and drives the protective cover A13 and the protective cover B14 to separate. Then, the protective cover A13 and the protective cover B14 drive the limiting block 12 to slide along the limiting groove 11. Thus, when the sensor body 1 is pulled out, the protective cover A13 and the protective cover B14 are automatically opened, facilitating the removal of the sensor body 1;

[0040] After the protective cover A13 and the protective cover B14 are opened, first hold the sensor body 1 and rotate it. When it rotates to a certain position, the slider 15 on the sensor body 1 coincides with the through groove 16. At this time, the sensor body 1 can be disassembled from the connecting plate 8, facilitating replacement.

[0041] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than a limitation on the protection scope of the present invention. Any simple modification or equivalent replacement made by those of ordinary skill in the art to the technical solution of the present invention shall not depart from the essence and scope of the technical solution of the present invention.
