Abstract
Description
Technical Field
[0001] This utility model relates to the field of detector technology, and in particular to a laser beam detector. Background Technology
[0002] A laser beam detector is a security device based on laser technology. It consists of a transmitter and a receiver. The transmitter emits a laser beam towards the receiver, creating an invisible laser warning line between them. When an object blocks the laser beam, the laser signal received by the receiver changes, triggering an alarm mechanism.
[0003] Among these applications, beam parallelization technology is of great significance in laser beam detectors. In numerous application scenarios, beam parallelization is a fundamental requirement.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a link, or a specific 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; and they can refer to the connection within two groups. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0039] like Figures 1-15 As shown, this utility model proposes a laser beam detector, which includes a housing 100, a cover 200, an adjustment mechanism 300, and a laser integrated module 400. The housing 100 is provided with a mounting groove 101. The cover 200 covers the housing 100 and covers the mounting groove 101. The cover 200 is provided with a window 201. The adjustment mechanism 300 is installed in the mounting groove 101. The laser integrated module 400 is installed on the adjustment mechanism 300 and is used to emit two beams that pass through the window 201. The laser integrated module 400 is used to adjust the emission angles of the two beams to be parallel. The adjustment mechanism 300 is used to adjust the deflection angle of the laser integrated module 400.
[0040] In this embodiment, both the shell 100 and the cover 200 are bowl-shaped structures with an opening on one side. The shape of this bowl-shaped structure can be customized according to actual needs, as shown in the attached figure. Figure 1 As shown, the housing 100 and the cover 200 adopt a long, bowl-shaped structure. The cover 200 has a transparent sheet such as a lens or filter placed at the window 201. The adjustment mechanism 300 and the laser integrated module 400 are both integrated in the mounting slot 101. The laser integrated module 400 can adjust the emission angle of the two beams it emits to make the beams parallel. The laser integrated module 400 is mounted on the adjustment mechanism 300. Under the adjustment operation of the adjustment mechanism 300, the laser integrated module 400 deflects at an angle relative to the housing 100, thereby adjusting the emission angle of the two beams. Compared with traditional laser beam detectors that cannot adjust the beam angle or still require external adjustment mechanisms to adjust the beam angle, the laser beam detector of this utility model adopts an adjustment mechanism with beam angle adjustment function built into it, achieving a compact structure and small volume, while adjusting the beam angle without the need for other external structures.
[0041] Furthermore, the laser integrated module 400 includes a housing 401 and two emitters 402 and multiple fine-tuning components 403, both mounted on the housing 401. The two emitters 402 are used to emit beams, and the multiple fine-tuning components 403 are respectively connected to the two emitters 402 to adjust the angle of the beams emitted by the two emitters 402 to be parallel.
[0042] Specifically, the two emitters 402 need to ensure that there is one visible light laser emitter and one invisible light laser emitter. The visible light laser emitter is used to assist the invisible light laser emitter. The most important aspect is ensuring that the beams of the two emitters 402 are parallel, so that the user can easily determine the emission path of the invisible light laser emitter using the visible light laser emitter. In this embodiment, the housing 401 has a small volume structure and only houses one visible light laser emitter and one invisible light laser emitter. The visible light laser emitter and the invisible light laser emitter are arranged side by side to ensure that their beams are parallel. Multiple fine-tuning components 403 are divided into two groups, and these two groups of fine-tuning components 403 correspond to two emitters 402, that is, connected to the corresponding visible light laser emitter or invisible light laser emitter. By adjusting the corresponding fine-tuning components 403, the placement angle of the visible light laser emitter and the invisible light laser emitter can be adjusted, thereby achieving fine-tuning of the beam emitted by the visible light laser emitter and the beam emitted by the invisible light laser emitter to be parallel to each other. Among them, the invisible light laser emitter needs to use a special detection instrument for identifying invisible light to determine the relative position of the invisible light emitted by it and the beam emitted by the visible light laser emitter.
[0043] Furthermore, the housing 401 is provided with two mounting holes 4011 and multiple fine-tuning holes 4012. The multiple fine-tuning holes 4012 are respectively connected to the two mounting holes 4011. The mounting holes 4011 are used to install the transmitter 402, and the fine-tuning holes 4012 are used to install the fine-tuning component 403. The fine-tuning component 403 extends into the mounting hole 4011 and is connected to the transmitter 402.
[0044] Specifically, to ensure that the transmitter 402 has adjustable space within the mounting hole 4011, the size of the mounting hole 4011 is larger than the size of the transmitter 402. This extra space is the fine-tuning space that the transmitter 402 can be adjusted by the fine-tuning component 403. It should be noted that in this embodiment, the fine-tuning component 403 is a precision screw structure, while the fine-tuning hole 4012 is a screw hole structure. In practical application, the fine-tuning component 403 enters from the fine-tuning hole 4012 and is placed within the mounting hole 4011, contacting the transmitter 402. Through this contact, different degrees of tightness are adjusted on each surface of the transmitter 402, thereby determining the placement position of the two transmitters 402 within the mounting hole 4011, so that the beams of the two transmitters 402 approach or become parallel.
[0045] More precise fine-tuning is achieved through a threaded fit to improve the accuracy of the beams of the two transmitters 402 approaching parallelism and reduce errors. It is important to note that the end of the fine-tuning component 403 adopts a planar or mating shape design that fits the contact surface with the transmitter 402, thereby increasing the contact area between the fine-tuning component 403 and the transmitter 402. This ensures that when it comes into contact with the transmitter 402, the fine-tuning effect can be guaranteed without damaging the transmitter 402 itself.
[0046] Supplementary information, as attached. Figure 13 As shown, the plurality of fine adjustment holes 4012 in each of the above groups are disposed in two orthogonal radial directions of the mounting hole 4011, and the plurality of fine adjustment holes 4012 in the same radial direction are arranged in an array along the axial direction of the mounting hole 4011.
[0047] Specifically, the arrangement of multiple fine-tuning holes 4012 in the two orthogonal radial directions of the mounting hole 4011 is for fine-tuning the x-axis and y-axis of the transmitter 402, as shown in the attached figure. Figure 15As shown, the top of the mounting hole 4011 is provided with an annular protrusion, which is used to ensure the normal emission of the beam from the transmitter 402 and also to position the transmitter 402 on the z-axis. Therefore, the z-axis does not need to be adjusted. Multiple fine-tuning holes arranged coaxially and in an array are used for fine-tuning the transmitter 402 in different directions on this axis. For example, two fine-tuning holes 4012 with a certain distance are provided coaxially. Assuming it is on the x-axis, the upper fine-tuning hole 4012 is placed where the fine-tuning component 403 extends into and abuts against the transmitter 402. Upon contact, the upper part of emitter 402 moves to the left relative to its lower part. This leftward movement is defined as the positive x-axis direction. Meanwhile, a fine-tuning element 403 extends into the lower fine-tuning hole 4012 and contacts the emitter 402. The lower part of emitter 402 moves to the right relative to its upper part, specifically in the negative x-axis direction. It's important to note that the positive and negative directions of movement are based on the beam emitted by emitter 402, and the leftward or rightward movement is only within the context of the emitter. Figure 15 To illustrate, the fine-tuning operation on the y-axis is the same as the fine-tuning operation on the x-axis described above, in order to perform more precise fine-tuning control on the two emitters 402, so that the beams emitted by the two emitters 402 can more accurately approach parallelism.
[0048] Furthermore, the housing 401 has two injection holes that correspond to the two mounting holes 4011 respectively.
[0049] Specifically, after the fine-tuning operation is performed on the two transmitters 402, in order to maintain the position of the two transmitters 402 for a long time and not be easily disturbed by external factors, in this embodiment, a gel-like substance such as sealant is injected into the injection hole to fix the two transmitters 402. After the sealant cures in the mounting hole 4011, it can wrap the two transmitters 402 and fix the two transmitters 402.
[0050] Furthermore, the adjustment mechanism 300 includes a bracket 301 and a deflector 302. The bracket 301 is installed in the mounting groove 101. The first end of the deflector 302 is rotatably connected to the bracket 301, and the second end of the deflector 302 is rotatably connected to the inner wall of the mounting groove 101. The interior of the deflector 302 is hollow, and the box 401 is rotatably installed inside the deflector 302. The deflection direction of the deflector 302 is orthogonal to the deflection direction of the box 401.
[0051] The adjustment mechanism 300 also includes a first adjustment member 303 and a second adjustment member 304. The first adjustment member 303 is connected to the bracket 301 and the deflector 302 respectively to adjust the deflection angle of the deflector 302. The second adjustment member 304 is connected to the deflector 302 and the laser integrated module 400 respectively to adjust the deflection angle of the box 401.
[0052] Specifically, the first adjusting member 303 is connected between the bracket 301 and the deflector 302. It is important to note that the connection between the first adjusting member 303 and the bracket 301 is a movable connection. Specifically, the first end of the first adjusting member 303 passes through a movable hole provided on the bracket 301 and is slidably connected therewith. The second end of the first adjusting member 303 is connected to a hole provided on the deflector 302, as shown in the attached figure. Figure 7 and attached Figure 8 As shown, in practical applications, the first end of the first adjusting member 303 has a limiting function, so that the end remains connected to the movable hole without disengaging. By adjusting the first adjusting member 303, the deflector 302 can be moved along the axial direction of the first adjusting member 303, thereby adjusting the fine adjustment of the left and right sway of the deflector 302. It should be noted that the first adjusting member 303 includes a screw structure with a helical spring sleeved on it, and the hole is a threaded hole. Of course, the hole can be a through hole and a copper nut structure can be injection molded and embedded.
[0053] The second adjusting member 304 has the same structure as the first adjusting member 303, and also adopts a screw and helical spring combination structure. In practical applications, by adjusting the second adjusting member 304, the laser integrated module 400 can be moved along the axis of the second adjusting member 304, thereby adjusting the fine adjustment of the front and rear swing of the laser integrated module 400.
[0054] To further improve the fine-tuning effect, screw structures with helical springs are set at the rotational connection of the deflector 302 and the laser integrated module 400. This increases the rotational resistance of the deflector 302 and the laser integrated module 400, ensuring that they are not easily affected by external interference. Moreover, when performing deflection fine-tuning, it can be adjusted in a small stroke to ensure the fine-tuning effect.
[0055] Furthermore, the outer wall of the housing 100 is provided with a slot 102, and the inner wall of the cover 200 is provided with a buckle 202. When the cover 200 covers the housing 100, the buckle 202 engages with the slot 102.
[0056] See appendix Figure 1-3 and appendix Figure 5The housing 100 and the cover 200 are fitted together with their openings facing each other. The cover 200 partially encloses the housing 100, causing part of the inner wall of the cover 200 to abut against part of the outer wall of the housing 100. To improve the installation effect, a snap-fit method using a buckle 202 and a slot 102 is used to achieve a fixed connection between the housing 100 and the cover 200. Furthermore, to improve the stability of the connection between the housing 100 and the cover 200, corresponding fixing holes are provided on the housing 100 and the cover 200. After mating, as shown in the attached figure... Figure 5 As shown, the two fixing holes are coaxial. In this case, pins, screws or other structures can be used to pass through these two fixing holes to achieve the fixing effect.
[0057] Furthermore, the laser beam detector also includes a first waterproof component 500. A waterproof groove 103 is provided on the outer wall of the housing 100. The first waterproof component 500 is installed in the waterproof groove 103. When the cover 200 is placed on the housing 100, the inner wall of the cover 200 abuts against the first waterproof component 500. The waterproof groove 103 is specifically positioned above the slot 102.
[0058] The laser beam detector also includes a second waterproof component 600. The housing 100 has a through hole 104 that communicates with the mounting groove 101. The second waterproof component 600 is installed at the through hole 104 and seals the through hole 104.
[0059] The second waterproof component 600 includes a positioning plate 601, a waterproof column 602, a pad 603, and a fixing component 604. The waterproof column 602 is hollow inside. The positioning plate 601 is installed on the waterproof column 602. The waterproof column 602 is installed in the through hole 104 and extends into the mounting groove 101. The positioning plate 601 is attached to the housing 100 and placed around the through hole 104. The pad 603 is attached to the positioning plate 601, and the pad 603 and the positioning plate 601 are fixed together to the housing 100 by the fixing component 604.
[0060] Specifically, the first waterproof component 500 is set inside the waterproof groove 103 and placed on the outer wall of the housing 100, between the outer wall of the mounting groove 101 and the inner wall of the cover 200, to fill the gap between the housing 100 and the cover 200, effectively isolating water stains from the outside and preventing water stains from entering the mounting groove 101 through the gap. Moreover, the cover 200 also adopts a semi-enclosed cover structure, which also prevents water stains from entering the mounting groove 101 from above the cover 200, thus improving the waterproof effect of this structure.
[0061] In this embodiment, the mounting groove 101 is used to install electronic components, circuit boards, data transmitters, and other structures. Therefore, it is necessary to introduce wires from the outside for electrical connection. Here, the wires pass through the through hole 104 into the mounting groove 101. The second waterproof component 600 is disposed at the through hole 104. When the wire passes through the through hole 104, the second waterproof component 600 wraps around a small section of the wire that passes through the through hole 104. This ensures that when the wire is introduced into the mounting groove 101, water stains can still be isolated from the outside by the second waterproof component 600, effectively improving the waterproof effect.
[0062] To facilitate the quick and accurate installation of the second waterproof component 600 into the through hole 104, a positioning plate 601 with positioning holes is provided on the second waterproof component 600. Multiple positioning posts are also correspondingly provided on the first side of the through hole 104. The second waterproof component 600 engages with the multiple positioning posts through the positioning holes on the positioning plate 601, achieving quick and accurate installation of the second waterproof component 600. The structure extending into the through hole 104 from the second waterproof component 600 is a waterproof post 602, the end of which is composed of multiple leaflets (simplified in the attached diagram). The deflection direction of the multiple leaflets is towards the central axis of the waterproof post 602. The wire extends from the post of the waterproof post 602... The waterproof column 602 penetrates through multiple leaflets and exits into the mounting groove 101. During this process, the column body and multiple leaflets of the waterproof column 602 are attached to the wire, effectively preventing water stains from entering the mounting groove 101 along the wire. It should be noted that the end of the waterproof column 602 may not be in the form of multiple leaflets. Specifically, it may be made of a puncturable material structure, that is, the end of the waterproof column 602 is closed, and the material used for the waterproof column 602 can be punctured. When the wire penetrates the waterproof column 602 and breaks its end, the broken leaflets formed at the end will also be attached to the wire, which can also achieve the waterproof effect.
[0063] Of course, the internal cavity of the waterproof column 602 can also be designed as a conical cavity structure. That is, when the wire is inserted into the waterproof column 602, it will be contacted and squeezed by the narrow inner wall of the cavity. It should be noted that the waterproof column 602 is preferably made of elastic material. Under the action of elastic deformation, while the wire can pass through the waterproof column 602, the part of the wire placed in the cavity will also be covered by the narrow inner wall of the cavity, which can also achieve a good waterproof effect.
[0064] Furthermore, the laser beam detector also includes a back plate 700. A wire hiding groove 105 is provided on the side of the housing 100 away from the cover 200. There are multiple connectors 1051 inside the wire hiding groove 105. The back plate 700 is provided with multiple hooks 701 that are detachably connected to the multiple connectors 1051 respectively.
[0065] Specifically, the backplate 700 is detached from the housing 100 to cover the cable tray 105. This cable tray 105 is used when multiple laser beam detectors are cascaded; the connecting cables pass through it. Therefore, for aesthetic reasons and to protect these cables, the backplate 700 covers the cable tray 105 to prevent damage and to ensure the overall aesthetic appearance of the housing 100, as shown in the attached diagram. Figure 6 As shown, the connector 1051 is specifically a protruding structure of the cable tray 105. In order to enable the end of the hook 701 to extend into the cable tray 105 when the back plate 700 covers the housing 100, and to engage with the connector 1051 through the hook 701, the back plate 700 and the housing 100 can be assembled. Of course, when disassembling, the back plate 700 and the housing 100 can be disassembled simply by moving the hook 701 away from the connector 1051, thus achieving a quick disassembly and assembly effect.
[0066] In this embodiment, in order to enhance the fixing effect between the back plate 700 and the housing 100, multiple screw fasteners are added, and studs that cooperate with the multiple screw fasteners are provided on the back plate 700.
[0067] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
