Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an adjustable photoelectric sensor. Background Art

[0002] Photoelectric sensors generally consist of two parts: a processing circuit and a processing element. Their basic principle is based on the photoelectric effect, which converts changes in the measured quantity into changes in the light signal. Photoelectric elements then further convert the non-electrical signal into an electrical signal. The photoelectric effect refers to the process of illuminating an object with light, which can be viewed as a series of photons with a certain energy bombarding the object. At this point, the photon energy is transferred to electrons, and the entire energy of a photon is absorbed by an electron at once. The electron's state changes as a result of the energy transferred by the photon, causing the object to produce a corresponding electrical effect.

[0003] Existing photoelectric sensors are generally screwed onto the equipment by tightening bolts. This installation method fixes the photoelectric sensor on the equipment, making it difficult to adjust its position. When the position of the pre-hole is deviated, it causes errors in the sensor assembly and the installation position of the photoelectric sensor cannot be quickly adjusted. Utility Model Content

[0004] In order to solve the above technical problems, an adjustable photoelectric sensor is provided.

[0005] In order to achieve the above purpose, the following solution is provided: an adjustable photoelectric sensor, comprising a sensor body, and also comprising a fixed base, an attraction module and a push-fit module, the attraction module being installed between the fixed base and the sensor body, the push-fit module being provided at the fixed base, the attraction module comprising a first magnetic plate and a second magnetic plate, the first magnetic plate being fixedly installed at the bottom of the sensor body, the second magnetic plate being fixedly installed on the fixed base, the first magnetic plate and the second magnetic plate being attracted to each other, a plurality of first latch teeth being evenly provided on the side of the first magnetic plate away from the sensor body, a plurality of second latch teeth being evenly provided on the side of the second magnetic plate away from the fixed base, the first latch teeth being adapted to the second latch teeth and the first latch teeth being engaged with the second latch teeth.

[0006] Furthermore, the pushing module includes a pressure plate and several pushing mechanisms. The pressure plate is installed at the end of the fixed base through several pushing mechanisms. The pressure plate is against the sensor body. The pushing mechanism includes a sliding rod, a slider and a pushing spring. One end of the sliding rod is fixedly connected to the pressure plate, and the other end of the sliding rod is inserted into the sliding groove in the fixed base. A sliding rod is provided at the end of the sliding rod away from the pressure plate. The slider is adapted to the sliding groove and the slider is slidably connected to the sliding groove. A pushing spring is installed between the slider and the fixed base, and the pushing spring is sleeved on the sliding rod.

[0007] Furthermore, fixed blocks are provided on both sides of the fixed base, fastening holes are opened on the fixed blocks, the fixed blocks protrude from the second magnetic plate, and the sensor body is located between the two fixed blocks.

[0008] Furthermore, a non-slip pad is provided at the bottom of the fixed base.

[0009] The working principle and advantages of the utility model are as follows: the adjustable photoelectric sensor allows the sensor body to be adsorbed on the fixed base through the first magnetic attraction plate and the second magnetic attraction plate, and the position of the sensor body can be adjusted by adjusting the engagement position of the first latch tooth and the second latch tooth.

[0015] The following is a further detailed description through specific implementation methods:

[0016] like Figures 1 to 3 As shown:

[0017] An adjustable photoelectric sensor includes a sensor body 1. The sensor body 1 is an existing mature product and will not be described in detail here. It also includes a fixed base 6, an suction module and a push module. The fixed base 6 is used to install the sensor body 1. The suction module is used to connect the fixed base 6 and the sensor body 1. The push module is used to squeeze the sensor body 1, so that the sensor body 1 and the fixed base 6 are connected more tightly and firmly through the suction module.

[0018] The attraction module includes a first magnetic plate 2 and a second magnetic plate 4. The first magnetic plate 2 is fixedly mounted on the bottom of the sensor body 1, and the second magnetic plate 4 is fixedly mounted on the fixed base 6. The first magnetic plate 2 and the second magnetic plate 4 are attracted to each other, so that the sensor body 1 can be attracted to the fixed base 6. The first magnetic plate 2 and the second magnetic plate 4 are respectively provided with a first latch 3 and a second latch 5. The first latch 3 and the second latch 5 are engaged, so that when the pushing module pushes the end of the sensor body 1, the first latch 3 and the second latch 5 are tightly engaged, and the sensor will not shift on the base.

[0019] The pushing module includes a pressure plate 8 and several pushing mechanisms. The pushing mechanisms are evenly arranged in the fixed base 6. The pushing module is connected to the pressure plate 8, so that the pressure plate 8 can push the end of the sensor body 1, thereby making the first latch 3 and the second latch 5 tightly engaged. The pushing mechanism includes a slide rod 10, a slider 11 and a pressure spring 12. A slide groove 9 is provided in the base, and the slider 11 is located in the slide groove 9. The slider 11 and the pressure plate 8 are connected through the slide rod 10. The slide rod 10 is provided with a pressure spring 12. The pressure spring 12 is located between the slider 11 and the slide groove 9, so that the pressure spring 12 can drive the pressure plate 8 to push the sensor body 1 through the slider 11 and the slide rod 10.

[0020] Fixed blocks 7 are provided on both sides of the fixed base 6. Fastening holes are opened on the fixed blocks 7. The fixed base 6 can be fixedly installed on the equipment through the fastening holes and corresponding fastening screws. The fixed blocks 7 protrude from the second magnetic plate 4, so that the sensor body 1 is located between the two fixed blocks 7.

[0021] The bottom of the fixed base 6 is provided with an anti-slip pad.

[0022] The specific implementation process is as follows:

[0023] When using this adjustable photoelectric sensor, first install the fixed base 6 on the equipment through the fixing blocks 7 on both sides of the fixed base 6 and the fastening screws, then pull the pressure plate 8 away from the fixed base 6, place the sensor body 1 between the two fixed blocks 7, adjust the position of the sensor body 1, and the first magnetic plate 2 at the bottom of the sensor body 1 and the second magnetic plate 4 at the top of the fixed base 6 can be attracted to each other, so that the first tooth 3 of the first magnetic plate 2 is engaged with the second tooth 5 of the second magnetic plate 4, and then release the pressure plate 8, so that the pressure plate 8 is pressed against the end of the sensor body 1 under the action of the top pressure spring 12 of the pushing mechanism, further making the first tooth 3 and the second tooth 5 tightly engaged, so that the sensor body 1 can be firmly installed on the fixed base 6.

[0024] This adjustable photoelectric sensor allows the sensor body 1 to be adsorbed on the fixed base 6 through the first magnetic plate 2 and the second magnetic plate 4. The position of the sensor body 1 can be adjusted by adjusting the engagement position of the first latch 3 and the second latch 5. At the same time, the sensor body 1 is pushed by the pushing module, so that the first latch 3 and the second latch 5 are tightly engaged, thereby enhancing the installation tightness of the sensor body 1 on the fixed base 6; this sensor can quickly and conveniently adjust the installation position of the sensor body 1, enhance the assembly accuracy of the sensor body 1 on the equipment, and meet the user's usage needs.
