Description

Technical Field

[0001] The present invention relates to an infrared pair tube device, and more particularly to an anti-interference infrared pair tube device. Background Art

[0002] An infrared pair tube is a commonly used sensor, including an infrared emitting tube and a photosensitive receiving tube. In the spectrum, the section with a wavelength greater than 0.76 microns is called infrared ray, which is invisible light. All substances above absolute zero (-273.15 °C) can generate infrared rays. Modern physics calls it thermal ray. Medical infrared rays can be divided into two categories: near-infrared rays and far-infrared rays.

[0003] The recognition principle of an infrared pair tube sensor is as follows: The infrared emitting pair tube emits infrared rays. After being reflected by an obstacle, the photosensitive receiving tube receives the reflected light of the object in front. When the object is dark, it will not reflect the infrared rays emitted by the infrared pair tube; for light-colored substances, they will absorb the infrared rays emitted by the infrared emitting tube. Therefore, whether the infrared emitting tube can accurately emit infrared rays and whether the photosensitive receiving tube can accurately receive the reflected infrared rays will determine the detection accuracy of the infrared pair tube sensor. In the prior art, there is no suitable fixing device for the infrared pair tube device, which causes certain inconvenience in the use of the infrared pair tube. At the same time, the conventional fixing device cannot realize the adjustment of the infrared pair tube in multiple directions, which also greatly limits the use of the infrared pair tube.

[0004] Therefore, those skilled in the art are committed to developing an anti-interference infrared pair tube device that can not only achieve multi-directional adjustment but also achieve anti-light interference. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an anti-interference infrared pair tube device that can not only achieve multi-directional adjustment but also achieve anti-light interference.

[0006] The technical solution of the present invention to solve the above technical problem is as follows: An anti-interference infrared pair tube device includes

[0007] a fixed platform, a first rotating platform, and a second rotating platform;

[0008] The fixed platform and the first rotating platform are connected by a vertical rotating mechanism. The first rotating platform is connected with the second rotating platform through a horizontal rotating mechanism. The second rotating platform is connected with an infrared module. An infrared sensor is arranged on the infrared module, and an anti-interference tube is installed outside the infrared sensor.

[0009] The beneficial effects of the present invention are as follows: Through the vertical rotation mechanism for vertical rotation and the horizontal rotation mechanism for horizontal rotation, each component located on the infrared module can move in multiple directions within the working space, thereby ensuring that the infrared sensor can adapt to different working environments; the anti-interference tube located outside the infrared sensor can effectively achieve anti-light interference and improve the accuracy of detection data.

[0010] Based on the above technical solutions, the present invention can be further improved as follows.

[0011] Further, the anti-interference tube is black and non-reflective.

[0012] The beneficial effect of adopting the above further solution is that the anti-interference tube is made of black non-reflective material, reducing the anti-light interference of the infrared sensor.

[0013] Further, the vertical rotation mechanism includes a first sleeve tube arranged on one side of the fixed platform, and a second sleeve tube and a vertical rotating member are arranged on the side of the first rotating platform;

[0014] A rotating pin is inserted into the first sleeve tube and the second sleeve tube, and the end of the vertical rotating member is inserted into the other first sleeve tube;

[0015] The rotating pin is conical.

[0016] The beneficial effect of adopting the above further solution is that the first rotating platform rotates vertically around the rotating pin, thereby realizing the adjustment in the vertical direction; the rotating pin is conical, and when the first rotating platform rotates to a suitable position, it is locked by the conical rotating pin to prevent the first rotating platform from further moving.

[0017] Further, the horizontal rotation mechanism includes a rotating hole arranged on the first rotating platform, the outer periphery of the upper side of the rotating hole is regular polygon, and the lower side of the rotating hole is cylindrical;

[0018] A rotating column is arranged on the second rotating platform, and the rotating column is provided with a multi-prism that cooperates with the upper side of the rotating hole and a cylinder that rotatably cooperates with the lower side of the rotating hole;

[0019] A spring is also sleeved outside the cylinder.

[0020] The beneficial effect of adopting the above further solution is that the second rotating platform can rotate horizontally around the rotating column, and thus the second rotating platform realizes horizontal rotation.

[0021] Further, the horizontal rotation mechanism includes a rotating threaded hole arranged on the first rotating platform;

[0022] A threaded column that cooperates with the rotating threaded hole is arranged on the second rotating platform, and a locking nut is also arranged at the top of the threaded column.

[0023] The beneficial effect of adopting the above further solution is that the second rotating platform can rotate horizontally around the threaded column, and thus the second rotating platform realizes horizontal rotation. After rotating to the specified position, the locking nut locks it to prevent the second rotating platform from further moving.

[0024] Furthermore, a socket strip is installed on the infrared module.

[0025] The beneficial effect of adopting the above further solution is that the socket strip is used to supply electrical energy to each component and exchange signals.

[0026] Furthermore, a potentiometer for adjusting the sensitivity of the infrared pair tube is also installed on the infrared module.

[0027] The beneficial effect of adopting the above further solution is that the potentiometer is electrically connected to the infrared sensor, and the potentiometer is used to adjust the sensitivity of the infrared sensor.

[0028] Furthermore, the infrared sensor includes an infrared pair tube emitter and a photosensitive receiver tube, and a partition board is arranged between the infrared pair tube emitter and the photosensitive receiver tube.

[0029] The beneficial effect of adopting the above further solution is that the partition board isolates the infrared pair tube emitter and the photosensitive receiver tube, reduces the signal interference between the two, and thus improves the detection sensitivity.

[0030] Furthermore, a plurality of fixed connection holes are arranged on the fixed platform.

[0031] The beneficial effect of adopting the above further solution is that the fixed connection holes are used to connect the fixed platform to other components. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an anti-interference infrared pair tube device includes a fixed platform 1, a first rotating platform 2, and a second rotating platform 3. Multiple fixed connection holes 20 are provided on the fixed platform 1, and the fixed connection holes 20 facilitate connecting the fixed platform 1 with other components. The fixed platform 1 and the first rotating platform 2 are connected by a vertical rotating mechanism. The first rotating platform 2 is connected to a second rotating platform 3 through a horizontal rotating mechanism. The second rotating platform 3 is connected to an infrared module 4. An infrared sensor 5 is provided on the infrared module 4, and an anti-interference tube 6 is installed outside the infrared sensor 5. Through the vertical rotation of the vertical rotating mechanism and the horizontal rotation of the horizontal rotating mechanism, each component located on the infrared module 4 can move in multiple directions within the working space, thereby ensuring that the infrared sensor 5 can adapt to different working environments. The anti-interference tube 6 located outside the infrared sensor 5 can effectively achieve anti-light interference and improve the accuracy of detection data.

[0043] In order to further improve anti-light interference, the anti-interference tube 6 is black and non-reflective. Specifically, the anti-interference tube 6 is made of a black non-reflective material to reduce the thermal radiation interference on the infrared sensor 5.

[0044] In some embodiments, the vertical rotating mechanism includes a first sleeve 7 provided on one side of the fixed platform 1. The number of the first sleeves 7 is selected according to the actual situation. In this embodiment, three first sleeves 7 are provided on one side of the fixed platform 1. A second sleeve 8 and a vertical rotating member 9 are provided on the side of the first rotating platform 2. A rotating pin 10 is inserted into the first sleeve 7 and the second sleeve 8, so that the first rotating platform 2 can rotate around the rotating pin 10. The end of the vertical rotating member 9 is inserted into another first sleeve 7. Specifically, one end of the vertical rotating member 9 has a cylinder, and the diameter of the cylinder is slightly smaller than the diameter of the first sleeve 7. The cylinder can rotate relative to the first sleeve 7.

[0045] The rotating pin 10 is conical. The conical rotating pin 10 facilitates fixing the first rotating platform 2 and the second sleeve 8 relative to each other when the first rotating platform 2 rotates to a suitable position.

[0046] The horizontal rotation mechanism includes a rotation hole 11 provided on the first rotation platform 2. The outer periphery of the upper side of the rotation hole 11 is a regular polygon, and the number of edges of the regular polygon is selected according to the actual situation. The more corresponding edges there are, the higher the accuracy of horizontal rotation adjustment. In this embodiment, the regular polygon is a regular decagon. The lower side of the rotation hole 11 is cylindrical, and the diameter of the cylinder is smaller than the diameter of the circumcircle of the regular polygon. A rotation column 12 is provided on the second rotation platform 3. The rotation column 12 is provided with a multi-prism that cooperates with the upper side of the rotation hole 11 and a cylinder that rotatably cooperates with the lower side of the rotation hole 11. The height of the cylinder is greater than the thickness of the first rotation platform 2. During the adjustment process, the second rotation platform 3 is lifted. After the multi-prism is separated from the upper part of the rotation column 12, the second rotation platform 3 is rotated. After rotating to the appropriate position, the second rotation platform 3 is lowered so that the multi-prism and the corresponding regular polygon are fitted and fixed.

[0047] A spring is sleeved outside the cylinder. One end of the spring abuts against the bottom of the first rotation platform 2, and the other end of the spring abuts against the upper side of the second rotation platform 3. The spring is used for stable self-locking.

[0048] In another embodiment, the horizontal rotation mechanism includes a rotation threaded hole 13 provided on the first rotation platform 2. A threaded column 14 that cooperates with the rotation threaded hole 13 is provided on the second rotation platform 3, and a locking nut is further provided at the top of the threaded column 14. During the adjustment process, after loosening the locking nut, the second rotation platform 3 can be rotated arbitrarily in the horizontal plane. After rotating to the appropriate position, it can be locked by the locking nut.

[0049] A socket strip 15 is installed on the infrared module 4. A plurality of external interfaces are provided on the socket strip 15 for supplying electric energy to the infrared sensor 5 and exchanging signals. A potentiometer 16 for adjusting the sensitivity of the infrared pair tube is also installed on the infrared module 4. The potentiometer 16 is adjusted according to the actual situation, and then the sensitivity of the infrared sensor 5 is adjusted.

[0050] In this embodiment, the infrared sensor 5 includes an infrared pair tube emitter 17 and a photosensitive receiver 19, which are respectively used for emitting infrared rays and receiving infrared rays. A partition plate 18 is provided between the infrared pair tube emitter 17 and the photosensitive receiver 19. The partition plate 18 separates the infrared pair tube emitter 17 and the photosensitive receiver 19 to prevent signal interference caused by the infrared pair tube emitter 17 and the photosensitive receiver 19 being too close to each other and affecting the detection accuracy.
