Description

Technical Field

[0001] The present application relates to the field of sensor technology, and in particular to an infrared sensor. Background Art

[0002] Infrared sensor is a sensor that uses infrared rays to process data. It has the advantages of high sensitivity. Infrared sensor can control the operation of the drive device.

[0003] Infrared sensors are commonly used for non-contact temperature measurement, gas analysis, and non-destructive testing, and are widely used in fields such as medicine, military, space technology, and environmental engineering. For example, using infrared sensors to remotely measure the surface temperature of the human body using thermal imaging can reveal areas with abnormal temperatures.

[0004] Infrared sensors are generally installed on the housing using a threaded lock method, that is, two sets of nuts are threaded on the infrared sensor. The two sets of nuts work together to fix the housing to ensure the tightness of the connection. This method of fixing is complicated and requires screwing in two sets of nuts. Too many nuts also affect the overall appearance. Summary of the Invention

[0005] In order to improve the above-mentioned problems, the present application provides an infrared sensor.

[0006] The infrared sensor provided in this application adopts the following technical solution:

[0007] An infrared sensor includes a sensor body, one end of which is a sensing end, and the other end is a connecting end, wherein the surface of the connecting end is provided with an external thread and a limiting groove;

[0008] A limiting member, plugged into the limiting groove;

[0009] A nut connected to an external mounting device, and the sensor body is screwed to the nut via an external thread;

[0010] During screw connection, the nut presses the limiting member, and the limiting member cooperates with the pressing of the nut to clamp and fix the sensor body.

[0011] By adopting the above technical solution, after the limit piece is taken out from the limit groove, the sensor body is screwed to the nut through the external thread, and the nut is rotated until the nut is located on the side close to the sensing end, and then the limit piece is inserted into the limit groove. The limit piece is against the groove wall of the limit groove, and the nut is rotated toward the limit piece, so that the nut is away from the sensing end and the limit piece is pressed. After the limit piece is pressed, pressure is applied to the sensor body to limit and tighten the sensor body in the limit groove, and the nut is connected to the external device or external installation point, thereby achieving the effect of facilitating installation and improving installation stability, while reducing the use of nuts and improving the overall appearance.

[0012] Optionally, the limiting member includes an annular portion and a plug-in portion; the diameter of the annular portion is larger than the diameter of the sensor body; the plug-in portion is fixedly mounted on the annular portion, and an external thread is provided on the plug-in portion; the plug-in portion matches the limiting groove, so that the plug-in portion and the limiting groove are socket-connected; when the plug-in portion and the limiting groove are socket-connected, the annular portion fits against the connecting end, and the external thread of the connecting end is docked with the external thread of the plug-in portion to complete the external thread.

[0013] By adopting the above technical solution, the plug-in part is inserted into the limiting groove, so that the external thread of the plug-in part is docked with the external thread of the connecting end to complete the external thread. After the external thread of the plug-in part is locked by the internal thread of the nut, the overall limiting part cannot be pulled out, ensuring the stability of the nut when it is screwed. At the same time, the plug-in part is pressed by the nut, and the pressing force is applied to the sensor body, and the annular part fits the connecting end to ensure a more stable fixing effect with the sensor body.

[0014] Optionally, the annular portion is a closed cover-like structure.

[0015] By adopting the above technical solution, when the annular portion is in contact with the connecting end, it can just cover the connecting end, provide support and tightness for the connecting end, and achieve the effect of protecting and stabilizing the sensor body.

[0016] Optionally, the plug-in portion is an arc-shaped sheet structure, and the external thread is located on the outer convex surface of the arc.

[0017] By adopting the above technical solution, the arc-shaped sheet structure creates a gap between the plug-in part and the limit groove, and the appearance is not abrupt. At the same time, the external thread of the convex surface can connect with the external thread on the surface of the sensor body, making it more stable when screwed with the nut.

[0018] Optionally, two corners of the plug-in portion close to the limiting groove are chamfered.

[0019] By adopting the above technical solution, the chamfering can prevent the corners of the plug-in part from being too sharp, and it is easier to fit into the limit groove when inserted into the limit groove.

[0020] Optionally, there are two limiting grooves, which are respectively located on both sides of the sensor body; and there are two groups of plug-in parts, which are respectively located on both sides of the annular part.

[0021] By adopting the above technical solution, when two groups of plug-in parts and limiting grooves are provided, when the nuts are tightened, the two groups of plug-in parts will press the sensor body from two directions at the same time, further increasing the pressing force and further improving the stability of the connection.

[0022] Optionally, the external thread on the sensor body starts from the connecting end, continues to open to the vicinity of the sensing end after exceeding the limiting groove, and does not cover the sensing end.

[0023] By adopting the above technical solution, the nut can be moved to a position beyond the limit slot and close to the direction of the sensing end, so that the limit slot will not be blocked by the nut, and then the limit piece can be inserted. After the limit piece is inserted, the nut will be rotated so that the nut is located on the outer wall of the limit piece, thereby achieving tightening. The length of the external thread opened in this way can facilitate the adjustment and adaptation of the nut position, avoiding affecting the installation of the limit piece and causing interference.

[0024] Optionally, when the plug-in portion is plugged into the limit groove, the plug-in depth is full plug-in or partial plug-in, and is screwed to the nut after plug-in; when partially plugged into, there is a gap between the annular portion and the connecting end, and the gap provides a connection point for installation.

[0025] By adopting the above technical solution, the two socket-spiking methods can make the installation methods of the infrared sensor more diversified and more adaptable.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. After removing the limit piece from the limit groove, screw the sensor body to the nut through the external thread and rotate it until the nut is located on the side close to the sensing end. Then insert the limit piece into the limit groove. The limit piece rests against the groove wall of the limit groove. Rotate the nut toward the limit piece, so that the nut is away from the sensing end and presses the limit piece. After the limit piece is pressed, pressure is applied to the sensor body to limit and tighten the sensor body in the limit groove. The nut is connected to the external device or external installation point, thereby facilitating installation and improving installation stability.

[0028] 2. Use the plug-in part to insert the limiting groove so that the external thread of the plug-in part is docked with the external thread of the connection end to complete the external thread. After the external thread of the plug-in part is locked by the internal thread of the nut, the overall limiting part cannot be pulled out, ensuring the stability of the nut when screwed. At the same time, the plug-in part is pressed by the nut, and the pressing force is applied to the sensor body, and the annular part fits the connection end to ensure a more stable fixing effect with the sensor body.

[0029] 3. When the annular part fits the connection end, it can just cover the connection end, provide support and tightness for the connection end, so as to achieve the effect of protecting and stabilizing the sensor body;

[0030] 4. The arc-shaped sheet structure creates a gap between the plug-in part and the limit groove, so the appearance will not be abrupt. At the same time, the external thread of the convex surface can connect with the external thread on the surface of the sensor body, making it more stable when screwed with the nut.

[0040] Throughout this specification, when a device is said to be "connected" to another device, this includes not only "direct connection" but also "indirect connection" with other elements interposed therebetween. Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0041] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0042] The embodiment of the present application discloses an infrared sensor.

[0043] An infrared sensor, reference Figure 1 and Figure 2 As shown, it includes a sensor body 1, one end of which is a sensing end 11, and the other end of which is a connecting end 12. The surface of the connecting end 12 is provided with an external thread and a limiting groove 13. The sensing end 11 can emit infrared rays to collect thermal imaging data information. The connecting end 12 is used to connect to an external mounting device, so it is connected to the limiting groove 13 by providing an external thread.

[0044] The limiting member 2 is plugged into the limiting groove 13 and is used to fix the sensor body 1 so as to provide a more stable fixing point when the sensor body 1 is installed on an external device.

[0045] The nut 3 is connected to the external mounting device, and the sensor body 1 is screwed to the nut 3 through an external thread. When screwed, the nut 3 covers part of the limiter 2 and presses the covered part. The limiter 2 cooperates with the compression of the nut 3 to clamp the sensor body 1, so that the sensor body 1 cannot be offset. At the same time, the compression effect is used to improve the tightness of the connection, increase stability and make the connection more beautiful.

[0046] Specifically, after the limit member 2 is taken out from the limit groove 13, the sensor body 1 is screwed to the nut 3 through the external thread, and rotated until the nut 3 is located on the side close to the sensing end 11, and then the limit member 2 is inserted into the limit groove 13. The limit member 2 is against the groove wall of the limit groove 13, and the nut 3 is rotated toward the limit member 2, so that the nut 3 is away from the sensing end 11 and the limit member 2 is pressed. After the limit member 2 is pressed, pressure is applied to the sensor body 1 to limit and tighten the sensor body 1 in the limit groove 13, and the nut 3 is connected to the external device or external installation point, thereby achieving the effect of facilitating installation and improving installation stability.

[0047] For further reference, Figure 1 and Figure 2 As shown, the limiting member 2 includes an annular portion 21 and an inserting portion 22 ; the inserting portion 22 is fixedly mounted on the annular portion 21 , and an external thread is provided on the inserting portion 22 , and the inserting portion 22 can be a plug-in plate or a plug-in sheet.

[0048] The diameter of the annular portion 21 is larger than the diameter of the sensor body 1 , so that when connected to an external structure, the annular portion 21 can rest against the wall surface of the external structure to achieve a compacting effect.

[0049] The plug-in part 22 matches the limiting groove 13 so that the plug-in part 22 and the limiting groove 13 are socket-connected. After the plug-in part 22 is drawn into the limiting groove 13, the external thread on the outer surface of the plug-in part 22 is aligned with the external thread of the sensor body 1, and the outer wall of the plug-in part 22 fits the inner wall of the limiting groove 13.

[0050] When the plug-in portion 22 is socket-connected with the limiting groove 13, the plug-in portion 22 reaches the end of the limiting groove 13, the annular portion 21 fits against the wall of the connecting end 12 and covers the connecting end 12, and the external thread at the connecting end 12 is docked with the external thread of the plug-in portion 22, completing the external thread and providing a stable screw connection effect when screwed with the nut 3.

[0051] Specifically, the plug-in part 22 is inserted into the limiting groove 13 so that the external thread of the plug-in part 22 is docked with the external thread of the connecting end 12 to complete the external thread. After the external thread of the plug-in part 22 is locked by the internal thread of the nut 3, the overall limiting part 2 cannot be pulled out, ensuring the stability of the nut 3 when it is screwed. At the same time, the plug-in part 22 is pressed by the nut 3, and the pressing force is applied to the sensor body 1, and the annular part 21 is fitted to the connecting end 12 to ensure a more stable fixing effect with the sensor body 1.

[0052] Further, refer to Figure 1As shown, the annular portion 21 is a closed cover-like structure. When the annular portion 21 is in contact with the connecting end 12, it can just cover the connecting end 12, provide support and tightness for the connecting end 12, and prevent the sensor body 1 from being loosened or damaged due to the force toward the annular portion 21 when it is bumped or hit during use. The annular portion 21 can just cover the connecting end 12, thereby achieving the effect of protecting and stabilizing the sensor body 1.

[0053] Furthermore, refer to Figure 1 As shown, the plug-in part 22 is an arc-shaped sheet structure, and the external thread is located on the outer convex surface of the arc. The arc-shaped sheet structure can fit the groove shape of the limiting groove 13 and the shape of the sensor body 1. After the plug-in part 22 is inserted into the limiting groove 13, it just fits the limiting groove 13, so that the gap between the plug-in part 22 and the limiting groove 13 is reduced, and the appearance will not be abrupt. At the same time, the external thread of the outer convex surface can connect with the external thread on the surface of the sensor body 1, making it more stable when screwed with the nut 3.

[0054] Among them, the two corners of the plug-in part 22 close to the limit groove 13 are chamfered. The chamfers can prevent the corners of the plug-in part 22 from being too sharp, and it is easier to integrate into the limit groove 13 when inserted into the limit groove 13. If there are sharp corners, it is easy to press against the limit groove 13, causing wear on the corners or the inner groove wall, affecting subsequent use and appearance.

[0055] Furthermore, there are two limit grooves 13, one on each side of the sensor body 1; there are two groups of plug-in parts 22, one on each side of the annular part 21. When two groups of plug-in parts 22 and limit grooves 13 are provided, when the nut 3 is tightened, the two groups of plug-in parts 22 will press the sensor body 1 from two directions at the same time, further increasing the pressing force and further improving the stability of the connection.

[0056] Among them, the outer walls of the limiting groove 13 and the plug-in part 22 can be provided with a rubber layer for anti-slip. The rubber layer can increase the friction and buffering capacity during compression, so that when the compression effect is guaranteed, the inner wall of the limiting groove 13 will not be damaged due to excessive force of the plug-in part 22.

[0057] Among them, the external thread on the sensor body 1 starts from the connecting end 12, and continues to open to the position close to the sensing end 11 after exceeding the limit groove 13, and does not cover the sensing end 11, so that when threaded with the nut 3, the nut 3 can move to a position close to the sensing end 11 after exceeding the limit groove 13, so that the limit groove 13 will not be blocked by the nut 3, and then the limit member 2 is inserted. After the limit member 2 is inserted, it is rotated so that the nut 3 is located on the outer wall of the limit member 2, thereby achieving tightening. The length of the external thread opened in this way can facilitate the adjustment and adaptation of the position of the nut 3, and avoid affecting the installation of the limit member 2 and causing interference.

[0058] In some embodiments, reference Figure 3 As shown, when the plug-in portion 22 is plugged into the limiting groove 13, the plug-in depth is full plug-in or partial plug-in, and is screwed to the nut 3 after plug-in; full plug-in means that the end of the plug-in portion 22 away from the annular portion 21 is completely inserted into the limiting groove 13 and abuts against the end of the limiting groove 13. This method can adapt to the connection between the nut 3 and the external device, and has an installation device or an installation point.

[0059] refer to Figure 2 As shown, when partially socketed, the finger joint 22 is not fully inserted into the limit groove 13, so that there is a gap 14 between the annular portion 21 and the connecting end 12. The gap 14 is a connection point for installation. If the installation point is a vertical rod or a vertical plate 4, the vertical plate 4 is taken as an example in the figure. The vertical plate 4 can be inserted into the gap 14, and then the nut 3 is used to cooperate with the annular portion 21 to clamp the vertical plate 4 to complete the installation. The two socket methods can make the installation method of the infrared sensor more diversified and more adaptable.

[0060] For further reference, Figure 4 As shown, when partial socket-jointing is adopted, a rubber sheet is further provided on the inner groove wall of the limiting groove 13, and a plurality of tooth-shaped grooves or dot-shaped grooves 15 are opened at one end of the rubber sheet close to the limiting groove 13. The opening positions of the tooth-shaped grooves or dot-shaped grooves 15 correspond to the inner grooves of the external thread. A rubber protrusion 23 is provided on the side wall of the plug-in portion 22. When the plug-in portion 22 is inserted into the limiting groove 13, the rubber protrusion 23 continuously moves along the tooth-shaped grooves or dot-shaped grooves 15 and is embedded in any one of the tooth-shaped grooves or dot-shaped grooves 15. The rubber protrusion 23 is located at the thread protrusion of the external thread.

[0061] The tooth-shaped grooves and the dot-shaped grooves 15 cooperate with the rubber protrusions 23, so that the position of the plug-in part 22 can be more accurate during the movement. That is, each time the rubber protrusion 23 bends and snaps into the next tooth-shaped groove or dot-shaped groove 15, the user can clearly feel the snap-in state of the rubber protrusion 23 through the vibration, so that the user can clearly judge whether the rubber protrusion 23 is located in any tooth-shaped groove or dot-shaped groove 15. If it is located in the tooth-shaped groove or dot-shaped groove 15, it means that the external thread of the plug-in part 22 is accurately docked with the external thread of the sensor body 1, avoiding the situation where the external thread of the plug-in part 22 is staggered with the external thread of the sensor body 1, causing the nut 3 to be stuck and unable to rotate. The dot-shaped groove 15 is taken as an example in the figure.

[0062] When fully inserted, there is no need to worry about the tooth-shaped groove or the dot-shaped groove 15. When the plug-in part 22 is directly inserted into the limiting groove 13, the external thread of the plug-in part 22 and the external thread of the sensor body 1 are in an accurate docking state.

[0063] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
