Description

Technical Field

[0001] This utility model relates to the field of sensor protection equipment technology, specifically a sensor protective housing. Background Technology

[0002] A sensor is a common and important device. It is a device or apparatus that senses various quantities that are specified to be measured and converts them into useful signals according to certain rules. For sensors, the input can be divided into static quantities and dynamic quantities according to the state of the input. We can obtain the static characteristics of the sensor based on the relationship between the output and input quantities under the steady state of each value. The main indicators of the static characteristics of a sensor include linearity, hysteresis, repeatability, sensitivity, and accuracy. The dynamic characteristics of a sensor refer to the response characteristics of the input quantity as the input quantity changes over time. Dynamic characteristics are usually described using automatic control models such as transfer functions.

[0003] To ensure the safety of sensors during use, they are usually protected by a protective shell. This protective shell typically ensures the stable operation of the sensor. However, the problem with this technology is that the assembly of the sensor with the protective shell requires multiple threaded components and connecting accessories, which makes the assembly process cumbersome and inconvenient for users to quickly assemble and use the sensor with the protective shell. This reduces the ease of use of the sensor and makes it inconvenient for users to use. Utility Model Content

[0008] Preferably, the protrusion has a transmission cavity, two transmission sliders are slidably arranged in the transmission cavity, a transmission gear is rotatably installed at the center of the transmission cavity, the transmission sliders have tooth grooves adapted to the transmission gears, and two locking blocks are respectively installed on the two transmission sliders.

[0009] Preferably, the transmission cavity is provided with two mutually symmetrical fixing blocks, each fixing block having a protruding guide rod, and both transmission sliders having guide holes adapted to the guide rods.

[0010] Preferably, a return spring is fitted on each of the two guide rods, with one end of the return spring abutting against the fixed block and the other end of the return spring abutting against the transmission slider.

[0011] Preferably, both connecting lugs are provided with connecting holes, through which connecting bolts for fixing the connecting lugs can be inserted.

[0012] Preferably, the transmission gear is connected to an adjustment knob that extends to the outside, and the adjustment knob has an anti-slip groove.

[0013] Compared with the prior art, this utility model provides a sensor protective housing with the following advantages: By providing a structure including protrusions, a mounting plate, and a protective housing, the two connector strips on the protective housing can be inserted into two connector slots on the mounting plate when connecting the protective housing to the mounting plate.

[0020] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-4 A protective housing for a sensor 19 includes a mounting plate 1, on the bottom of which the sensor 19 is mounted, and on the top of which a protrusion 3 is provided. A protective shell 6 is detachably connected to the bottom of the mounting plate 1. The protective shell 6 has multiple through holes 7 and covers the outside of the sensor 19. Two symmetrical plug strips 5 protrude from the top of the protective shell 6. Two symmetrical plug grooves 18 that are adapted to the plug strips 5 are provided on the mounting plate 1. Locking blocks 10 are slidably arranged on both sides of the protrusion 3. Locking holes 15 that are adapted to the locking blocks 10 are provided on the plug strips 5. Two connecting ear plates 2 are provided on the top of the mounting plate 1.

[0023] By incorporating the protrusions 3, mounting plate 1, and protective shell 6, the two connector strips 5 on the protective shell 6 can be inserted into the two connector slots 18 on the mounting plate 1 when connecting the protective shell 6 to the mounting plate 1. This positions the two connector strips 5 on the left and right sides of the two protrusions 3. At this time, the two locking blocks 10 inside the protrusions 3 are inserted into the locking holes 15 inside the two connector strips 5 to limit and fix their positions, thereby completing the installation and fixing of the protective shell 6. This simplifies the installation steps of the protective shell 6 and improves the maintenance efficiency of the sensor 19.

[0024] Specifically, in this embodiment, a transmission cavity 8 is provided in the protrusion 3, and two transmission sliders 9 are slidably arranged in the transmission cavity 8. A transmission gear 11 is rotatably installed at the center position of the transmission cavity 8. A tooth groove 16 adapted to the transmission gear 11 is provided on the transmission slider 9, and two locking blocks 10 are respectively installed on the two transmission sliders 9.

[0025] By cooperating with the transmission gear 11 and transmission slider 9, the two transmission sliders 9 can be moved closer or further apart by rotating the transmission gear 11, thereby achieving the purpose of adjusting the position of the two locking blocks 10.

[0026] Specifically, in this embodiment, two mutually symmetrical fixing blocks 12 are provided in the transmission cavity 8. A guide rod 13 protrudes from the fixing block 12, and a guide hole 17 adapted to the guide rod 13 is provided on each of the two transmission sliders 9.

[0027] By setting the guide rod 13, the transmission slider 9 can slide along the guide rod 13 through the guide hole 17, thereby guiding the movement direction of the transmission slider 9 and making the movement process of the transmission slider 9 smoother.

[0028] Specifically, in this embodiment, a reset spring 14 is sleeved on each of the two guide rods 13. One end of the reset spring 14 abuts against the fixed block 12, and the other end of the reset spring 14 abuts against the transmission slider 9.

[0029] By setting the return spring 14, the two transmission sliders 9 can be kept away from each other in a non-human state, so that the two locking blocks 10 on the two transmission sliders 9 can be pressed against the locking holes 15 on the two plug strips 5, thereby ensuring a stable connection between the plug strips 5 and the mounting plate 1.

[0030] Specifically, in this embodiment, each of the two connecting ear plates 2 is provided with a connecting hole 4, and a connecting bolt for fixing the connecting ear plate 2 can be inserted into the connecting hole 4 to realize the connection and fixation between the connecting ear plate 2 and the frame.

[0031] Specifically, in this embodiment, the transmission gear 11 is connected to an adjustment knob 20 extending to the outside. The adjustment knob 20 has an anti-slip groove, and the transmission gear 11 can be rotated by adjusting the knob 20.
