Description

Technical Field

[0001] This utility model relates to the field of laser light source housings, and in particular to an integrated adjustable lens frame housing structure for a laser light source. Background Technology

[0002] In traditional laser light source optical path systems, the lens mount typically consists of a fixed plate (fixed to the housing) and a movable plate (adjustable component). The fixed plate, as an independent component, requires a screw-locking structure (e.g., thickened sheet metal, reserved installation space), while the movable plate's adjustment mechanism further increases its size, resulting in low utilization of the housing's internal space. Therefore, improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide an integrated adjustable lens frame housing structure for laser light sources to address the problem of low internal space utilization in traditional laser light source optical path systems.

[0004] This utility model provides an integrated adjustable lens frame housing structure for a laser light source, comprising:

[0005] A fixed plate has a cavity, and its bottom has a symmetrical first countersunk hole, and its sidewalls have symmetrical second countersunk holes;

[0006] The moving plate is located inside the cavity and has symmetrical first through holes and symmetrical locking holes on its surface, and symmetrical positioning holes on its sidewall. The positioning holes and locking holes are interconnected and perpendicular to each other. Each first through hole has a symmetrical limiting groove. The first through hole is coaxial with the corresponding first countersunk hole, and the positioning hole is coaxial with the corresponding second countersunk hole.

[0007] The tensioning mechanism is installed in the area formed by the combination of the limiting groove, the first through hole, and the first countersunk hole;

[0008] The locking mechanism is installed in the area formed by the combination of the locking hole, the positioning hole, and the second countersunk hole.

[0009] In one embodiment, the tensioning mechanism includes a fixing ring fixed in a first countersunk hole, a connecting rod fixedly connected to the inner wall of the fixing ring, a limiting rod engaged in the limiting groove, and a tension spring sleeved between the limiting rod and the connecting rod.

[0010] In one embodiment, the positioning hole and the corresponding locking hole are combined to form a T-shaped channel.

[0011] In one embodiment, the locking mechanism includes a positioning block that engages with a second countersunk hole. A connector and a compression spring are fixedly connected to the side wall of the positioning block. The connector passes through the compression spring, and the free end of the compression spring abuts against the inner wall of the fixed plate. A second through hole is provided at the free end of the connector. The second through hole is coaxial with the locking hole. A locking rod is inserted into the locking hole, and the locking rod is located in the second through hole.

[0012] In one embodiment, the fixed plate has symmetrical first adjustment holes on its sidewall, and the moving plate has three second adjustment holes on its surface. The three second adjustment holes are combined to form a triangle. An adjustment mechanism is installed in each of the first and second adjustment holes. The adjustment mechanism is used to adjust the height and angle of the moving plate.

[0013] In one embodiment, the adjusting mechanism includes a sleeve fixed in a first adjusting hole or a second adjusting hole, the inner wall of the sleeve being threaded with a screw, one end of the screw having an internal hexagonal groove, and the other end of the screw having a hemisphere.

[0014] The integrated adjustable lens frame housing structure of the aforementioned laser light source saves longitudinal space within the cavity by integrating the fixed plate with the cavity sidewall of the traditional housing. This solves the problems of large space occupation and low installation accuracy of existing split lens frames, and achieves compactness and high precision of the optical path adjustment mechanism. At the same time, the integrated structure eliminates stress concentration at the connection interface, improves the vibration resistance of the fixed plate, and significantly improves long-term stability.

[0028] The following is combined with Figures 1-5 This invention describes the integrated adjustable lens frame housing structure of the laser light source.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, an integrated adjustable lens frame housing structure for a laser light source includes a fixed plate 100, a movable plate 200, a tensioning mechanism 300, and a locking mechanism 400.

[0030] The fixed plate 100 has a cavity 110, the bottom of the fixed plate 100 has a symmetrical first countersunk hole 120, and the side wall of the fixed plate 100 has a symmetrical second countersunk hole 130.

[0031] It should be noted that the laser source housing is formed by CNC machining of a single piece of substrate. The inner wall of the housing or the pre-installed area is directly machined into an integrated plate, without any independent separate parts.

[0032] The movable plate 200 is located inside the cavity 110. The surface of the movable plate 200 has symmetrical first through holes 210 and symmetrical locking holes 240. The side wall of the movable plate 200 has symmetrical positioning holes 230. The positioning holes 230 and the locking holes 240 are interconnected and perpendicular to each other. Each first through hole 210 has a symmetrical limiting groove 220. The first through hole 210 is coaxial with the corresponding first countersunk hole 120. The positioning hole 230 is coaxial with the corresponding second countersunk hole 130.

[0033] The tensioning mechanism 300 is installed in the area formed by the combination of the limiting groove 220, the first through hole 210, and the first countersunk hole 120.

[0034] The locking mechanism 400 is installed in the area formed by the combination of the locking hole 240, the positioning hole 230, and the second countersunk hole 130.

[0035] The moving plate 200 can be installed in the cavity 110 of the fixed plate 100 by means of the tensioning mechanism 300 and the locking mechanism 400.

[0036] The integrated adjustable lens frame housing structure of this laser source saves longitudinal space within the cavity by integrating the fixed plate 100 with the side wall of the cavity 110 on the traditional housing. This solves the problems of large space occupation and low installation accuracy of existing split lens frames, and achieves compactness and high precision of the optical path adjustment mechanism. At the same time, the integrated structure eliminates stress concentration at the connection interface, improves the vibration resistance of the fixed plate 100, and significantly improves long-term stability.

[0037] In this embodiment, see Figure 3 The tensioning mechanism 300 includes a fixing ring 310 fixed in the first countersunk hole 120, a connecting rod 320 fixedly connected to the inner wall of the fixing ring 310, a limiting rod 340 being engaged in the limiting groove 220, and a tension spring 330 being sleeved between the limiting rod 340 and the connecting rod 320.

[0038] It should be noted that the length of the limiting rod 340 is the same as the outer diameter of the fixing ring 310. During assembly, the fixing ring 310 is fixed in the first countersunk hole 120, and then the tension spring 330 passes through the first countersunk hole 120 and the first through hole 210 in sequence. Finally, the connecting rod 320 passes through the free end of the tension spring 330 and is engaged in the limiting groove 220.

[0039] In this embodiment, see Figure 4 The locking mechanism 400 includes a positioning block 410 that is engaged in the second countersunk hole 130. The side wall of the positioning block 410 is fixedly connected to a connector 420 and a compression spring 450. The connector 420 passes through the compression spring 450. The free end of the compression spring 450 abuts against the inner wall of the fixed plate 100. The free end of the connector 420 is provided with a second through hole 430. The second through hole 430 is coaxial with the locking hole 240. A locking rod 440 is inserted into the locking hole 240. The locking rod 440 is located in the second through hole 430.

[0040] It should be further explained that the positioning hole 230 and the corresponding locking hole 240 combine to form a T-shaped channel. During assembly, the positioning block 410 is placed in the second countersunk hole 130, and then the free end of the connector 420 passes through the second countersunk hole 130 and the positioning hole 230 in sequence. At this time, the second through hole 430 and the locking hole 240 are coaxial. Finally, the locking rod 440 is inserted into the locking hole 240. At this time, the locking rod 440 is located in the second through hole 430, and the locking rod 440 and the connector 420 combine to form a T-shape.

[0041] In the traditional design, the fixed plate 100 is installed as a separate component within the cavity 110, and the adjustment position is on the fixed plate 100. This necessitates that the adjustment of the movable plate 200 be performed within the cavity 110. If the cover is closed, the movable plate 200 can no longer be adjusted. Therefore, in this embodiment, see... Figure 1 The fixed plate 100 has symmetrical first adjustment holes 140 on its side wall, and the moving plate 200 has three second adjustment holes 250 on its surface. The three second adjustment holes 250 are combined to form a triangle. An adjustment mechanism 500 is installed in both the first adjustment hole 140 and the second adjustment hole 250. The adjustment mechanism 500 is used to adjust the height and angle of the moving plate 200.

[0042] In this embodiment, see Figure 5 The adjusting mechanism 500 includes a sleeve 510 fixed in the first adjusting hole 140 or the second adjusting hole 250. The inner wall of the sleeve 510 is threaded with a screw 520. One end of the screw 520 has an internal hexagonal groove 530, and the other end of the screw 520 has a hemisphere 540.

[0043] It should be further explained that the side wall of the moving plate 200 has a V-shaped groove 260. The hemisphere 540 of the adjusting mechanism 500 in one of the first adjusting holes 140 abuts against the V-shaped groove 260 to resist the pressure of the compression spring 450 and limit the position of the fixed plate 100. The hemisphere 540 of the adjusting mechanism 500 in the other first adjusting hole 140 abuts against the side wall of the moving plate 200, and the hemisphere 540 of the adjusting mechanism 500 in the second adjusting hole 250 abuts against the surface of the fixed plate 100.

[0044] The angle of the moving plate 200 can be easily adjusted by adjusting the screw 520 in the first adjustment hole 140, and the height of the moving plate 200 can be easily adjusted by adjusting the screw 520 in the second adjustment hole 250. Even if the cover plate of the cavity 110 has been installed and sealed, the angle of the moving plate 200 can still be adjusted through the first adjustment hole 140, thereby adjusting the optical path as needed without opening the cover. This makes the adjustment of the moving plate 200 possible not only inside the cavity 110 but also outside the cavity 110, making the adjustment of the moving plate 200 more convenient and providing a larger operating space.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
