Description

Technical Field

[0001] The present invention relates to the technical field of detectors, and in particular to a laser beam detector. Background Art

[0002] 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 to the receiver, forming an invisible laser warning line between the two. When an object blocks the laser beam, the laser signal received by the receiver changes, and the detector triggers an alarm mechanism.

Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or a connection, or a specific connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between two groups. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0038] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-Figure 15 As shown, the present invention proposes a laser beam detector, which includes a shell 100, a cover body 200, an adjustment mechanism 300 and a laser integrated module 400. The shell 100 is provided with a mounting groove 101, the cover body 200 covers the shell 100 and covers the mounting groove 101, the cover body 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 light beams and pass through the window 201, the laser integrated module 400 is used to adjust the emission angles of the two light beams to be parallel, wherein the adjustment mechanism 300 is used to adjust the deflection angle of the laser integrated module 400.

[0040] In this embodiment, the housing 100 and the cover 200 are both in a bowl-shaped structure with one side open, and the shape design of the bowl-shaped structure can be customized according to actual needs, such as the attached Figure 1 As shown, the shell 100 and the cover body 200 adopt a long bowl-shaped structure, wherein the cover body 200 is placed in parallel at the window 201, and a transparent sheet such as a lens or a filter is provided, and the adjustment mechanism 300 and the laser integrated module 400 are integrated in the installation groove 101, wherein the laser integrated module 400 has the function of adjusting the emission angle of the two light beams emitted by itself to make the light beams parallel, and the laser integrated module 400 is installed on the adjustment mechanism 300, and under the adjustment operation of the adjustment mechanism 300, the laser integrated module 400 can be angularly deflected relative to the shell 100, thereby adjusting the emission angle of the two light beams. Compared with the traditional laser beam detector that cannot adjust the angle of the light beam, or still needs other external adjustment mechanisms to adapt to achieve the adjustment of the light beam angle, the laser beam detector of the present invention adopts an adjustment mechanism with a beam angle adjustment function built into it, so as to achieve a compact structure and a small volume, and the beam angle can be adjusted without the use of other external structures.

[0041] Furthermore, the laser integrated module 400 includes a box body 401 and two emitters 402 and a plurality of fine-tuning parts 403 both mounted on the box body 401. The two emitters 402 are used to emit light beams, and the plurality of fine-tuning parts 403 are respectively connected to the two emitters 402 to adjust the angles of the light beams emitted by the two emitters 402 to be parallel.

[0042] Specifically, it is necessary to ensure that one visible light laser transmitter and one invisible light laser transmitter are included in the two transmitters 402, wherein the visible light laser transmitter is used to assist the use of the invisible light laser transmitter. Of course, the most important thing here is to ensure that the light beams of the two transmitters 402 are parallel, so that it is convenient for users to determine the emission path of the invisible light laser transmitter through the visible light laser transmitter. In this embodiment, the box body 401 is a small volume structure and only one visible light laser transmitter and one invisible light laser transmitter are loaded thereon. The visible light laser transmitter and the invisible light laser transmitter are arranged side by side to ensure that the light beams of the two are parallel. , multiple fine-tuning parts 403 are divided into two groups, and the two groups of fine-tuning parts 403 are corresponding to the two emitters 402, that is, connected to the corresponding visible light laser emitter or invisible light laser emitter, and the placement angles of the visible light laser emitter and the invisible light laser emitter are adjusted by adjusting the corresponding fine-tuning parts 403, so as to achieve fine-tuning of the light beam emitted by the visible light laser emitter and the light beam emitted by the invisible light laser emitter to be parallel to each other, wherein the invisible light laser emitter needs to use a detection instrument specially used to identify invisible light to determine the relative position of the invisible light emitted by it and the light beam emitted by the visible light laser emitter.

[0043] Furthermore, two mounting holes 4011 and a plurality of fine-tuning holes 4012 are provided on the box body 401. The plurality of 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 part 403, wherein the fine-tuning part 403 penetrates into the mounting holes 4011 and is connected to the transmitter 402.

[0044] Specifically, in order to ensure that the emitter 402 has adjustable space in the mounting hole 4011, the size of the mounting hole 4011 should be larger than the size of the emitter 402, and this extra space is the fine-tuning space in which the emitter 402 can be adjusted by the fine-tuning member 403. It should be noted that in this embodiment, the fine-tuning member 403 is specifically a precision screw structure, and the fine-tuning hole 4012 is a screw hole structure. In actual application, the fine-tuning member 403 enters from the fine-tuning hole 4012 and is placed in the mounting hole 4011 to conflict with the emitter 402. Through this conflict method, different degrees of tightness are adjusted for each surface of the emitter 402, thereby determining the placement position of the two emitters 402 in the mounting hole 4011, so that the light beams of the two emitters 402 are approached or parallel.

[0045] More precise fine-tuning operations are achieved through threaded matching to improve the accuracy of the parallelism of the light beams of the two emitters 402 and reduce errors. It should be noted that the end of the fine-tuning member 403 adopts a flat surface or a shape structure design that fits the contact surface of the emitter 402 to increase the contact area between the fine-tuning member 403 and the emitter 402, ensuring that when it contacts the emitter 402, the fine-tuning effect can be guaranteed without damaging the emitter 402 body.

[0046] Supplementary, such as Fig.13 As shown, the multiple fine-tuning holes 4012 in each group are arranged in two orthogonal radial directions of the mounting hole 4011 , and the multiple fine-tuning holes 4012 in the same radial direction are arranged in an axial array along the mounting hole 4011 .

[0047] Specifically, the arrangement of the plurality of fine-tuning holes 4012 in 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 Fig.15As shown, it can be seen that the top of the mounting hole 4011 is provided with an annular protrusion, which is used to ensure that the light beam of the emitter 402 is normally emitted, and also locates the position of the emitter 402 on the z-axis, so the z-axis does not need to be adjusted. The multiple fine-tuning holes arranged in a coaxial direction and in an array are respectively used for fine-tuning the emitter 402 in different directions under the axis. For example, two fine-tuning holes 4012 with a certain spacing are arranged on the coaxial axis. Assuming that it is under the x-axis, the fine-tuning hole 4012 placed on the upper layer is arranged when the fine-tuning member 403 extends into and contacts the emitter 402. When the upper part of the emitter 402 is touched, it moves to the left relative to its lower part. Here, the direction of movement to the left is defined as the positive direction of the x-axis. The fine-tuning member 403 is inserted into the fine-tuning hole 4012 of the lower layer and contacts the emitter 402. The lower part of the emitter 402 moves to the right relative to its upper part, specifically, toward the negative direction of the x-axis. It should be noted that the positive and negative directions of movement here are based on the light beam emitted by the emitter 402, and the movement to the left or right is only in the vicinity of the Fig.15 It is explained in the figure for the sake of understanding, and the fine-tuning operation on the y-axis is the same as the fine-tuning operation on the x-axis mentioned above, so as to perform more precise fine-tuning control on the two emitters 402, so that the light beams emitted by the two emitters 402 can be more accurately approached to parallelism.

[0048] To supplement, the box body 401 is provided with two injection holes corresponding to and connected to the two mounting holes 4011 respectively.

[0049] Specifically, after the fine-tuning operation is performed on the two emitters 402, in order to maintain the positions of the two emitters 402 for a long time and not be easily disturbed by external factors, in the present embodiment, a sealant or other colloid used to fix the two emitters 402 is injected from the injection hole. After the sealant solidifies in the mounting hole 4011, the two emitters 402 can be wrapped and fixed.

[0050] Furthermore, the adjustment mechanism 300 includes a bracket 301 and a deflection body 302, the bracket 301 is installed in the installation groove 101, the first end of the deflection body 302 can be rotatably connected to the bracket 301, the second end of the deflection body 302 can be rotatably connected to the inner wall of the installation groove 101, the deflection body 302 is hollow inside, and the box body 401 can be rotatably installed inside the deflection body 302, wherein the deflection direction of the deflection body 302 is orthogonal to the deflection direction of the box body 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 respectively connected to the bracket 301 and the deflection body 302 to adjust the deflection angle of the deflection body 302. The second adjustment member 304 is respectively connected to the deflection body 302 and the laser integrated module 400 to adjust the deflection angle of the box body 401.

[0052] Specifically, the first adjusting member 303 is connected between the bracket 301 and the deflection body 302. It should be noted that the first adjusting member 303 is connected to the bracket 301 in an active connection manner. Specifically, the first end of the first adjusting member 303 passes through the active hole set on the bracket 301 and is connected therein in a sliding connection manner, and the second end of the first adjusting member 303 is connected to the hole set on the deflection body 302. Figure 7 and attached Figure 8 As shown, in actual application, the first end of the first adjusting member 303 has a limiting function, so that the end remains connected to the movable hole and does not detach. By adjusting the first adjusting member 303, the deflection body 302 can be moved along the axial direction of the first adjusting member 303, thereby adjusting the left and right deflection of the deflection body 302. It should be noted that the first adjusting member 303 includes a screw structure with a coil spring, and the hole position is a threaded hole. Of course, the hole position can be selected as 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 matching structure of a screw and a coil spring. In actual application, by adjusting the second adjusting member 304, the laser integrated module 400 can be moved along the axial direction of the second adjusting member 304, thereby fine-tuning the front and rear deflection of the laser integrated module 400.

[0054] In order to further improve the fine-tuning effect, a screw structure with a coil spring is provided at the rotation connection of the deflection body 302 and the laser integrated module 400, so that the rotation resistance of the deflection body 302 and the laser integrated module 400 is increased to ensure that they are not easily affected by external interference, and when performing deflection fine-tuning, small adjustments can be made with a small stroke to ensure the fine-tuning effect.

[0055] Furthermore, a slot 102 is provided on the outer wall of the shell 100 , and a buckle 202 is provided on the inner wall of the cover body 200 . When the cover body 200 is covered on the shell 100 , the buckle 202 is engaged with the slot 102 .

[0056] See attached Figure 1-3 And attached Figure 5The shell 100 and the cover 200 are fitted together with one side of the opening facing each other, wherein the cover 200 is half-wrapped on the shell 100, which also makes part of the inner wall of the cover 200 conflict with part of the outer wall of the shell 100. In order to improve the installation effect, the buckle 202 and the card slot 102 are used to achieve the fixed connection between the shell 100 and the cover 200. Further, in order to improve the stability of the connection between the shell 100 and the cover 200, the shell 100 and the cover 200 are provided with corresponding fixing hole structures. After matching, as shown in the attached Figure 5 As shown, the two fixing hole structures are coaxial. In this case, a pin, a screw or the like can be used to pass through the two fixing hole structures to achieve a 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 shell 100, and the first waterproof component 500 is installed in the waterproof groove 103, wherein when the cover body 200 is covered on the shell 100, the inner wall of the cover body 200 abuts against the first waterproof component 500, wherein the waterproof groove 103 is specifically placed above the card slot 102.

[0058] The laser beam detector further includes a second waterproof member 600 . The housing 100 is provided with a through hole 104 connected to the mounting groove 101 . The second waterproof member 600 is installed at the through hole 104 and closes 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, and 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 installation groove 101. The positioning plate 601 is attached to the shell 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 to the shell 100 together through the fixing component 604.

[0060] Specifically, the first waterproof member 500 is arranged in 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 body 200, so as to fill the gap between the housing 100 and the cover body 200, effectively isolating water stains from the outside, and preventing water stains from entering the mounting groove 101 from the gap. In addition, the cover body 200 also adopts a semi-wrapped cover structure, which also prevents water stains from entering the mounting groove 101 from the top of the cover body 200, thereby improving the waterproof effect of this structure.

[0061] In this embodiment, the interior of the installation groove 101 is used to install electronic components, circuit boards, data transmitters and other structures, so it is necessary to introduce wires from the outside for electrical connection. Here, the wires are inserted into the interior of the installation groove 101 from the through hole 104, and the second waterproof component 600 is arranged at the through hole 104. When the wire passes through the through hole 104, the second waterproof component 600 is wrapped around a small section of the wire that passes through the through hole 104, so that when the wire is introduced into the installation groove 101, water stains can still be isolated on the outside by the second waterproof component 600, thereby effectively improving the waterproof effect.

[0062] In order to facilitate the second waterproof member 600 to be quickly and accurately installed in the through hole 104, a positioning plate 601 with a positioning hole is provided on the second waterproof member 600, and a plurality of positioning posts are correspondingly provided on the first side of the through hole 104. The second waterproof member 600 is engaged with the plurality of positioning posts through the positioning holes on the positioning plate 601, so as to realize the quick and accurate installation of the second waterproof member 600. Among them, the second waterproof member 600 extends into the through hole 104 with a waterproof post 602 structure, the end of which is composed of a plurality of leaf petals (only briefly shown in the attached figure), the deflection direction of the plurality of leaf petals is toward the central axis of the waterproof post 602, and the wire is extended from the column of the waterproof post 602 The waterproof column 602 penetrates the wire body and passes out from the multiple leaf petals into the installation groove 101. During this period, the column body and the multiple leaf petals of the waterproof column 602 are attached to the wire, which can effectively prevent water stains from entering the installation 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 leaf petals, but specifically adopts a breakable 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 residual leaves formed by the broken end will also be attached to the wire, which can also achieve a waterproof effect.

[0063] Of course, the internal column cavity of the waterproof column 602 can also be designed as a conical chamber structure, that is, when the wire passes through the waterproof column 602, it is contacted and squeezed by the narrow inner wall of the column cavity. It should be noted that the waterproof column 602 here is preferably made of elastic material. Under the action of elastic deformation, the wire can pass through the waterproof column 602, and the part of the wire placed in the column cavity will also be adhered to the narrow part of the inner wall of the column cavity, which can also achieve a good waterproof effect.

[0064] Furthermore, the laser beam detector also includes a back plate 700, and a wire storage groove 105 is provided on the side of the shell 100 away from the cover body 200, and there are multiple connecting parts 1051 in the wire storage groove 105, and multiple hooks 701 are provided on the back plate 700, which are detachably connected to the multiple connecting parts 1051.

[0065] Specifically, the back plate 700 and the housing 100 are disassembled and assembled in order to cover the wire groove 105. The wire groove 105 is used for connecting the wires to each other when multiple laser beam detectors are used for cascading. Therefore, for the sake of beauty and protection of the wires, the back plate 700 is used to cover the wire groove 105 to avoid damage to the wires therein and to ensure the beauty of the overall structure of the housing 100. Figure 6 As shown, the connecting piece 1051 is specifically a protruding structure of the wire hiding groove 105. When the back panel 700 covers the shell 100, the end of the hook 701 extends into the wire hiding groove 105, and the hook 701 is engaged with the connecting piece 1051 to realize the assembly of the back panel 700 and the shell 100. Of course, when disassembling, it is only necessary to move the hook 701 in a direction away from the connecting piece 1051 to realize the disassembly of the back panel 700 and the shell 100, thereby 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 , a plurality of screw fixing members are added, and studs cooperating with the plurality of screw fixing members are provided on the back plate 700 .
