Description

Technical Field

[0001] This application belongs to the field of manufacturing auxiliary parts for lens or lens testing, specifically a light source mounting base. Background Technology

[0002] When testing lenses or mirrors, it's necessary to change the angle at which the test light illuminates the same point on the lens or mirror to comprehensively test its light transmission efficiency, refractive index, and other properties. Therefore, a non-circular guide rail is typically used. An arc-shaped moving base is then installed on the guide rail to fix the light source and allow it to move along the arc-shaped rail. The test point on the lens or mirror is located at the corresponding center of the non-circular guide rail, thus changing the angle of the test light without moving the lens or mirror. Currently, a coaxial groove is cut into the non-circular guide rail, and a roller located within the groove is installed on the base. This allows the base to move along the guide rail without falling off. However, this method is more complicated because machining the groove is difficult, increasing manufacturing costs. Utility Model Content

[0003] The purpose of this application is to address the shortcomings of existing technologies by designing a light source mounting base that combines a top rail slider with a rail-holding slider on the base. In use, the top rail slider presses against the inner circumference of the arc-shaped guide rail, while the rail-holding slider holds the outer circumference of the arc-shaped guide rail, thus clamping the guide rail. This avoids the need to cut grooves in the arc-shaped guide rail for mounting the base and solves the problem that current light source mounting bases require slotted arc-shaped guide rails.

[0004] To achieve the above objectives, the technical solution adopted in this application is:

[0005] A light source mounting base includes a base body, a light source mounting structure on the front of the base body, a top rail slider on the back of the base body, and a rail-holding slider that cooperates with the top rail slider on the base body.

[0006] Preferably, the top rail slider includes a roller and a telescopic top rod. At least two telescopic top rods are fixedly installed on the back of the seat, with a preset angle between the two telescopic top rods. Each telescopic top rod has a roller on one end facing away from the seat.

[0007] Preferably, the roller is a swivel wheel.

[0008] Preferably, the roller is a first roller, the two telescopic top rods are located in the same plane A, the axle of the first roller is perpendicular to the plane A, and the plane A is not perpendicular to the plane B where the sliding path of the top rail slider is located.

[0009] Preferably, plane A is parallel to plane B.

[0010] Preferably, the top rail slider is a smooth curved surface disposed on the back of the seat, and the smooth curved surface is an incomplete cylindrical curved surface.

[0011] Preferably, the central angle of the smooth curved surface is greater than 45°.

[0012] Preferably, the rail-holding slider includes a first support leg, a second support leg, a third roller, and a fourth roller. The first support leg and the second support leg are fixedly provided on opposite sides of the base body. The first support leg and the second support leg are located on opposite sides of the sliding direction of the top rail slider. The third roller and the fourth roller are respectively provided at the ends of the first support leg and the second support leg away from the base body. The axle of the third roller and the axle of the fourth roller are parallel to each other, and the axle of the third roller is perpendicular to the sliding direction of the top rail slider.

[0013] Preferably, the third roller is located on the side of the first support leg facing the second support leg, and the fourth roller is located on the side of the second support leg facing the first support leg.

[0014] Preferably, both the first leg and the second leg are telescopic rods.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] This application employs a control device capable of connecting to two power sources. This device enables a single device to connect to two control power sources, allowing the other power source to be automatically activated when one control power source is disconnected. This solves the problem that current devices can only connect to one control power source, forcing them to shut down when that control power source is disconnected. Attached Figure Description

Arc-shaped guide rail. Detailed Implementation

[0023] like Figure 1-5 As shown, a light source mounting base includes a base body 1, a light source mounting structure 14 on the front side of the base body 1, a top rail slider on the back side of the base body 1, and a rail-holding slider that cooperates with the top rail slider on the base body 1.

[0024] In this application, during use, the light source is mounted on the light source mounting structure 14. Then, the top rail slider presses against the inner circumferential surface of the arc-shaped guide rail 13, and the clamping rail slider clamps the outer circumferential surface of the arc-shaped guide rail 13. This prevents the base 1 from radially detaching from the arc-shaped guide rail 13. In other words, the clamping rail slider and the top rail slider together clamp the arc-shaped guide rail 13, but this does not affect the sliding of the base 1 on the arc-shaped guide rail 13. Finally, the angle at which light illuminates the lens can be adjusted by changing the position of the base 1 on the arc-shaped guide rail 13. The light source mounting structure 14 can be a magnet. During use, the magnetic base of the light source is placed directly on the light source mounting structure, and the magnet's magnetic force attracts the base of the light source, thus mounting the light source.

[0025] In a preferred embodiment, the top rail slider includes a roller and a telescopic top rod. At least two telescopic top rods are fixedly mounted on the back of the base 1, with a preset angle between the two telescopic top rods. Each telescopic top rod has a roller at its end facing away from the base. This arrangement of the telescopic top rods facilitates the integration of the top rail slider and the rail-holding slider with arc-shaped guide rails 13 of varying thicknesses. The rollers reduce friction when the base 1 moves on the arc-shaped guide rail 13.

[0026] As a preferred embodiment, the roller is a caster wheel.

[0027] In a preferred embodiment, the roller is a first roller 4, and the two telescopic top rods are located in the same plane A5. The axle of the first roller 4 is perpendicular to plane A5, and plane A5 is not perpendicular to plane B6, where the sliding path of the top rail slider is located. Because the sliding path of the top rail slider is the plane containing the arc of the arc guide rail 13, when plane A5 is perpendicular to plane B6, when one of the telescopic top rods presses against the arc guide rail 13, the base 1 will rotate around the axle of the first roller 4, thus affecting the angle of light when inspecting the lens.

[0028] Specifically, the telescopic top rod includes a first sub-rod 3 and a first top cylinder 2 with one end open. One end of the first sub-rod 3 is inserted into the first top cylinder 2 and is axially slidably connected to the first top cylinder 2. The end of the first top cylinder 2 facing away from the first sub-rod 3 is fixedly connected to the back of the base body 1. A first roller 4 is provided on the end of the first sub-rod 3 facing away from the first top cylinder 2. A screw hole is provided on the side wall of the first top cylinder 2 near the opening. A bolt is screwed into the screw hole from the outside of the first top cylinder 2 and abuts against the side wall of the first sub-rod 3.

[0029] As a preferred arrangement, plane A5 is parallel to plane B6. This arrangement is more aesthetically pleasing and facilitates installation. Of course, plane A5 and plane B6 can overlap.

[0030] As a preferred embodiment, the top rail slider is a smooth curved surface 7 disposed on the back of the base 1, and the smooth curved surface 7 is an incomplete cylindrical curved surface. With this configuration, the top rail slider can only abut against the arc-shaped guide rail 13, whose inner diameter is equal to the radius of the virtual cylinder containing the smooth curved surface 7. However, this method provides greater stability because the smooth curved surface 7 and the arc-shaped guide rail 13 are in surface-to-surface contact.

[0031] As a preferred embodiment, the central angle of the smooth surface 7 is greater than 45°.

[0032] In a preferred embodiment, the rail-holding slider includes a first support leg, a second support leg, a third roller 18, and a fourth roller 12. The first support leg and the second support leg are fixedly mounted on opposite sides of the base 1, respectively. The first support leg and the second support leg are located on opposite sides of the sliding direction of the top rail slider. The third roller 18 and the fourth roller 12 are respectively mounted at the ends of the first support leg and the second support leg away from the base 1. The axles of the third roller 18 and the fourth roller 12 are parallel to each other, and the axle of the third roller 18 is perpendicular to the sliding direction of the top rail slider. With this configuration, during use, both the third roller 18 and the fourth roller 12 roll in contact with the outer circumferential surface of the arc-shaped guide rail 13, thereby holding the arc-shaped guide rail 13 without restricting the movement of the base 1 on the arc-shaped guide rail 13.

[0033] Specifically, the third roller 18 is located on the side of the first support leg facing the second support leg, and the fourth roller 12 is located on the side of the second support leg facing the first support leg.

[0034] As a preferred embodiment, both the first and second supports are telescopic rods. With this configuration, the first and second supports, in conjunction with the telescopic top rod forming a top rail slider, allow this application to cooperate with arc-shaped guide rails 13 of different radii.

[0035] Specifically, the first support leg includes a second top cylinder 8 and a second sub-rod 9, and the second support leg includes a third top cylinder 10 and a third sub-rod 11. One end of the second top cylinder 8 is open, and one end of the second sub-rod 9 is inserted into the second top cylinder 8 and axially slidably connected to the second top cylinder 8. The third roller 18 is provided on the end of the second sub-rod 9 facing away from the second top cylinder 8. The seat body 1 is fixedly connected to the end of the second top cylinder 8 facing away from the second sub-rod 9. A screw hole is provided on the side wall of the second top cylinder 8 near the opening, and a bolt is screwed in from the outside of the second top cylinder 8. The screw hole abuts against the side wall of the second sub-rod 9; one end of the third top cylinder 10 is open, and one end of the third sub-rod 11 is inserted into the third top cylinder 10 and axially slidably connected to the third top cylinder 10. The fourth roller 12 is provided on the end of the third sub-rod 11 facing away from the third top cylinder 10. The end of the third top cylinder 10 facing away from the third sub-rod 11 is fixedly connected to the base body 1. A screw hole is provided on the side wall of the third top cylinder 10 near the opening. A bolt is screwed into the screw hole from the outside of the third top cylinder 10 and abuts against the side wall of the third sub-rod 11. After this configuration, in use, the side of the third roller 18 and the fourth roller 12 facing the base body 1 is first brought into contact with the outer circumferential surface of the arc-shaped guide rail 13. At this time, the third sub-rod 11 will move axially relative to the third top cylinder 10. Then, the third sub-rod 11 is fixed relative to the third top cylinder 10 by screwing the bolt on the third top cylinder 10 into the screw hole. Similarly, the second sub-rod 9 will also slide axially relative to the second top cylinder 8, and then the bolt on the second top cylinder 8 can be screwed into the screw hole on the second top cylinder 8 to lock the second sub-rod 9.

[0036] Preferably, the seat 1 is further provided with a guide rail brake, which includes a brake threaded hole 15 and a brake screw 16. The brake threaded hole 15 penetrates the front and back of the seat 1, and the two ends of the brake screw 16 engage with the brake threaded hole 15. During use, when it is necessary to fix the seat 1 relative to the arc-shaped guide rail 13, the brake screw 16 is rotated until one end of the brake screw 16 presses against the circumferential surface of the arc-shaped guide rail 13 to achieve the braking effect. Preferably, one end of the brake screw 16 is provided with a rubber pad 17. During use, the end of the brake screw 16 with the rubber pad 17 faces the inner circumferential surface of the arc-shaped guide rail 13. This increases the friction when fixing the seat 1 relative to the arc-shaped guide rail 13 and also protects the arc-shaped guide rail 13, preventing the brake screw 16 from leaving marks on the inner circumferential surface of the arc-shaped guide rail 13 when it presses against it.
