Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric sensors, in particular to a photoelectric sensor which is convenient for disassembly and assembly. Background Technique

[0002] A photoelectric sensor is a device that converts a light signal into an electrical signal. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon that when light irradiates on certain substances, the electrons of the substances absorb the energy of photons and generate corresponding electrical effects.

[0003] After retrieval, a utility model with the Chinese patent publication number CN206959870U discloses a photoelectric sensor protection device which is convenient for disassembly and assembly, including a light emitter, a reflector, a light receiver and an installation component. The light emitter, the reflector and the light receiver are fixedly installed at the edge of a dangerous area through the installation component. The light emitted by the light emitter enters the light receiver through the light receiving groove after being refracted by the reflector. A plurality of photoelectric sensors are installed at the bottom of the light receiving groove. The input end of the light emitter is electrically connected with a control switch through a wire.

[0004] Many existing photoelectric sensors are connected by bolts after drilling holes in external devices. If disassembly is required, all bolts need to be unscrewed, and the disassembly and assembly process is relatively inconvenient, leaving room for improvement. Therefore, a photoelectric sensor which is convenient for disassembly and assembly is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a photoelectric sensor which is convenient for disassembly and assembly, so as to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a photoelectric sensor which is convenient for disassembly and assembly, including a mounting plate, a clamping component is installed at the bottom of the mounting plate. The clamping component includes two sliding rods fixedly connected to one side of the outer wall of the bottom of the mounting plate. A limiting sleeve is slidably sleeved outside each of the two sliding rods. The same clamping plate is fixedly connected to one end of the bottom of the two limiting sleeves. One side of the outer wall of the top of the clamping plate is fixedly connected with a threaded sleeve. A screw rod is threadedly connected inside the threaded sleeve. One end of the screw rod is rotatably connected inside the mounting plate.

[0007] As a further preference of the technical solution, a knob is rotatably connected to the outer wall of the top of the mounting plate. The knob is coaxially fixed with one end of the screw rod, and the diameter of the knob is larger than the diameter of the screw rod.

[0008] The sensor body can be quickly fixed or removed without damaging external equipment, and no external tools are required. It is easy to operate and has strong stability. The screw is driven to rotate inside the mounting plate by turning the knob, and the sliding rod connected to the mounting plate is inserted into the limit sleeve on the top of the splint, which can ensure that the splint can move horizontally but cannot rotate. Therefore, the threaded sleeve connected to the splint cannot rotate either. Therefore, when the screw rotates, the threaded sleeve and the splint are driven close to the mounting plate until the splint is tightly squeezed against the outer wall of the external device. At this time, the sensor body will also be fixed.

[0009] As a further preferred embodiment of the present technical solution, an adjustment assembly is installed on the top of the mounting plate, and the adjustment assembly includes a rotating disk rotatably connected to the top outer wall of the mounting plate, a limit card is coaxially fixed to the top outer wall of the rotating disk, and a sensor body is placed inside the limit card.

[0010] As a further preferred embodiment of the present technical solution, a protrusion is fixedly connected to the outer walls at both ends of the sensor body, and the two protrusions are slidably connected to the internal slide groove of the limit card. A bolt is threadedly connected to the inside of the two protrusions, and the two bolts can fit with the outer wall of the limit card.

[0011] As a further preferred embodiment of the present technical solution, an extension plate is fixedly connected to the circumferential outer wall of the rotating disk, an insertion rod is slidably inserted inside the extension plate, a spring is sleeved on the outside of the insertion rod, both ends of the spring are respectively fixedly connected to the insertion rod and the extension plate, and a plurality of equidistantly distributed positioning holes are opened on the top outer wall of the mounting plate, and the insertion rod can enter into the plurality of positioning holes.

[0012] The orientation of the sensor body can be adjusted at will according to needs, and it is more adaptable. For example, if the horizontal direction of the sensor body needs to be adjusted, just pull the rod upward, the spring will be stretched, and one end of the rod will also be out of the positioning hole. Then turn the rotating disk, and the sensor body on the top will rotate synchronously with the rotating disk. If the vertical direction of the sensor body needs to be adjusted, just turn the bolt so that it no longer contacts the outer wall of the limit card. At this time, just push the protrusion to drive the sensor body to slide in the limit card. When it reaches a suitable height, turn the bolt again to make it contact the limit card. Under the action of friction, the position of the sensor body will be fixed.

[0013] As a further preferred embodiment of the present technical solution, the thread lead angle of the screw is smaller than the equivalent friction angle.

[0014] As a further preferred embodiment of the present technical solution, outer walls of the mounting plate and the clamping plate close to each other are provided with a plurality of anti-slip pads distributed at equal distances, and the plurality of anti-slip pads are distributed at equal distances.

[0015] The utility model provides a photoelectric sensor that is easy to disassemble and assemble, and has the following beneficial effects:

[0016] (1) By providing a clamping assembly, the present utility model can achieve quick fixing or disassembly of the sensor body without damaging external devices, and without the need for external tools, with convenient operation and strong stability. By rotating the knob to drive the screw to rotate inside the mounting plate, the slide bar connected to the mounting plate is inserted into the limit sleeve at the top of the clamping plate, which can ensure that the clamping plate can translate but cannot rotate. Therefore, the threaded sleeve connected to the clamping plate also cannot rotate. Thus, when the screw rotates, it can drive the threaded sleeve and the clamping plate to approach the mounting plate until the clamping plate tightly presses against the outer wall of the external device, and at this time, the sensor body will also be fixed.

[0017] (2) By providing an adjustment assembly, the present utility model enables the orientation of the sensor body to be adjusted arbitrarily according to needs, with stronger adaptability. For example, if it is necessary to adjust the horizontal direction of the sensor body, just pull the insertion rod upward, the spring will be stretched, and one end of the insertion rod will also disengage from the positioning hole. Then, turn the rotating disk, and the sensor body on its top will rotate synchronously with the rotating disk. If it is necessary to adjust the vertical direction of the sensor body, just rotate the bolt so that it no longer contacts the outer wall of the limit card. At this time, just push the convex block to drive the sensor body to slide in the limit card. When it reaches the appropriate height, then rotate the bolt to make it contact the limit card, and under the action of friction, the position of the sensor body will be fixed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] The present utility model provides a technical solution: As Figure 1 and Figure 2 shown, in this embodiment, an easily disassembled and assembled photoelectric sensor includes a mounting plate 1. A clamping assembly 4 is installed at the bottom of the mounting plate 1. The clamping assembly 4 includes two sliding rods 401 fixedly connected to one side of the outer wall at the bottom of the mounting plate 1. A limiting sleeve 402 is slidably sleeved outside each of the two sliding rods 401. The same clamping plate 403 is fixedly connected to one end at the bottom of the two limiting sleeves 402. A threaded sleeve 405 is fixedly connected to one side of the outer wall of the clamping plate 403. A screw rod 404 is threadedly connected inside the threaded sleeve 405. One end of the screw rod 404 is rotatably connected inside the mounting plate 1.

[0025] A knob 406 is rotatably connected to the outer wall at the top of the mounting plate 1. The knob 406 is coaxially fixed to one end of the screw rod 404, and the diameter of the knob 406 is greater than the diameter of the screw rod 404, which can increase the transmission force arm, thereby ensuring that the driving process is easy enough.

[0026] By rotating the knob 406 to drive the screw rod 404 to rotate inside the mounting plate 1, and the sliding rod 401 connected to the mounting plate 1 is inserted into the limiting sleeve 402 at the top of the clamping plate 403, it can be ensured that the clamping plate 403 can translate but cannot rotate. Therefore, the threaded sleeve 405 connected to the clamping plate 403 also cannot rotate. Therefore, when the screw rod 404 rotates, it can drive the threaded sleeve 405 and the clamping plate 403 to approach the mounting plate 1 until the clamping plate 403 tightly presses against the outer wall of the external device. At this time, the sensor body 3 will also be fixed.

[0027] As Figure 2 、 Figure 3 and Figure 4 shown, an adjusting assembly 5 is installed at the top of the mounting plate 1. The adjusting assembly 5 includes a rotating disk 501 rotatably connected to the outer wall at the top of the mounting plate 1. A limiting card 502 is coaxially fixed to the outer wall at the top of the rotating disk 501. The sensor body 3 is placed inside the limiting card 502.

[0028] A convex block 503 is fixedly connected to each of the outer walls at both ends of the sensor body 3. The two convex blocks 503 are both slidably connected to the inner chute of the limiting card 502. A bolt 504 is threadedly connected inside each of the two convex blocks 503. The two bolts 504 can be attached to the outer wall of the limiting card 502.

[0029] The outer circumferential wall of the rotating disk 501 is fixedly connected with an extension plate 505. An insertion rod 506 is slidably inserted into the extension plate 505. A spring 507 is sleeved on the outer part of the insertion rod 506. Two ends of the spring 507 are respectively fixedly connected with the insertion rod 506 and the extension plate 505. A plurality of positioning holes 508 which are equidistantly distributed are formed in the outer wall of the top of the mounting plate 1, and the insertion rod 506 can enter into the plurality of positioning holes 508.

[0030] If it is necessary to adjust the horizontal direction of the sensor body 3, only need to pull the insertion rod 506 upwards, the spring 507 will be stretched, and one end of the insertion rod 506 will also disengage from the positioning hole 508. Then, turn the rotating disk 501, and the sensor body 3 on its top will rotate synchronously with the rotating disk 501. If it is necessary to adjust the vertical direction of the sensor body 3, only need to rotate the bolt 504 so that it no longer contacts the outer wall of the limit card 502. At this time, only need to push the convex block 503 to drive the sensor body 3 to slide in the limit card 502. After it reaches the appropriate height, rotate the bolt 504 again to make it contact the limit card 502. Under the action of friction, the position of the sensor body 3 will be fixed.

[0031] As Figure 2 shown, the lead angle of the screw 404 is smaller than the equivalent friction angle, so that it has self-locking property, thereby ensuring that the clamping effect will not change randomly.

[0032] As Figure 1 and Figure 2 shown, anti-slip pads 2 which are equidistantly distributed are arranged on the outer walls of the mounting plate 1 and the clamping plate 403 which are close to each other. The plurality of anti-slip pads 2 are equidistantly distributed, which can increase the static friction between the two and the external equipment, and is beneficial to increasing the clamping effect.

[0033] The utility model provides an optoelectronic sensor which is convenient for disassembly and assembly. The specific working principle is as follows:

[0034] When the device is working, the mounting plate 1 and the clamping plate 403 are sleeved on the outside of the plate or column of the external device, and then the screw 404 is driven to rotate inside the mounting plate 1 by turning the knob 406. The sliding rod 401 connected to the mounting plate 1 is inserted into the limiting sleeve 402 on the top of the clamping plate 403, which can ensure that the clamping plate 403 can translate but cannot rotate. Therefore, the threaded sleeve 405 connected to the clamping plate 403 cannot rotate either. Therefore, the screw 404 rotates, which can drive the threaded sleeve 405 and the clamping plate 403 to approach the mounting plate 1 until the clamping plate 403 is tightly pressed against the outer wall of the external device. At this time, the sensor body 3 will also be fixed. If the sensor body needs to be adjusted, In the horizontal direction of the body 3, as long as the insertion rod 506 is pulled upward, the spring 507 will be stretched, and one end of the insertion rod 506 will also be out of the positioning hole 508, and then the rotating disk 501 is turned, and the sensor body 3 on the top will rotate synchronously with the rotating disk 501. If you need to adjust the vertical direction of the sensor body 3, just turn the bolt 504 so that it no longer contacts the outer wall of the limit card 502. At this time, just push the protrusion 503 to drive the sensor body 3 to slide in the limit card 502. When it reaches a suitable height, turn the bolt 504 to make it contact the limit card 502. Under the action of friction, the position of the sensor body 3 will be fixed.
