Description

Technical Field

[0001] This utility model belongs to the field of projection lamp technology, specifically relating to an optical lens assembly and a projection lamp having the optical lens assembly. Background Technology

[0002] Projectors with optical lens assemblies are efficient and flexible lighting devices widely used in outdoor lighting, advertising lighting, stage lighting, and other fields. As the name suggests, projectors with optical lens assemblies are equipped with specially designed optical lens assemblies. These lens assemblies are typically made of optical glass or plastic and have specific shapes and curvatures to control the propagation and focusing of light. During operation, light emitted from the light source is refracted and reflected by the lens assemblies, forming specific light spots and lighting effects. Users can change the output direction and distribution of light by adjusting the angle and position of the lens assemblies. Existing projectors have the following problems during use:

[0003] Existing ground-mounted floodlights primarily rely on inserting a pole directly into the ground for fixation. However, this method has significant limitations. Especially in loose soil or areas with high moisture content, the stability of the pole is greatly reduced because the soil's support for the pole is significantly diminished. Furthermore, if the floodlight is subjected to external forces during use, such as strong winds or human impact, it is prone to tipping over if secured solely by the pole. This not only affects the floodlight's illumination but also poses a potential threat to the surrounding environment and the safety of people. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a projector with an optical lens assembly. This projector aims to solve the obvious limitations of the existing fixing method that relies solely on inserting a pole into the ground. When the soil is loose or has a high moisture content, the stability of the pole is greatly reduced because the soil's support for the pole is significantly decreased. Furthermore, the projector is prone to tipping over when subjected to external forces during use.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a projection lamp with an optical lens assembly. The projection lamp includes a lens assembly, a rotating support, and a plug rod. The rotating support is mounted on the surface of the lens assembly, and the plug rod is connected to the bottom side of the rotating support. A second bearing is installed inside the plug rod, and a worm gear is connected through the inside of the second bearing. A knob is connected to the top of the worm gear. A horizontal shaft is connected to the side surface of the plug rod, and the horizontal shaft is connected through the inside of a third bearing. A worm wheel is connected to the outer surface of the third bearing, and a support leg is connected to the surface of the worm wheel.

[0008] When using the floodlight using this technical solution, the worm gear rotates, driving the worm wheel to rotate through the meshing structure. The rotation of the worm wheel can drive the support leg to rotate. Thus, when the floodlight is inserted into the ground through the insertion rod, the support leg can support the insertion rod, thereby maintaining the stability of the floodlight.

[0009] Preferably, the worm gear forms a rotating structure with the insert rod through the second bearing. When the knob is turned, it can drive the worm gear to rotate inside the second bearing, thus achieving the driving effect of the worm gear.

[0010] Furthermore, four sets of horizontal shafts, third bearings, worm gears, and support legs are arranged in a circular array on the outer surface of the insertion rod. The worm gear forms a rotating structure with the horizontal shaft through the third bearing. When the worm gear is subjected to force, it can rotate on the surface of the horizontal shaft through the third bearing.

[0011] Furthermore, the worm and worm wheel form a meshing structure. When the worm wheel rotates, its helical surface meshes tightly with the gear surface of the worm wheel, thereby causing the worm wheel to rotate along an axis perpendicular to the worm. When the worm wheel rotates, it can drive the support legs to rotate, and the stability of the floodlight can be maintained by the support of the support legs.

[0012] An optical lens assembly includes a housing, a lens sheet, and a lamp source main board. The lens sheet is connected inside the housing, and the lamp source main board is installed inside the housing. A limiting groove is formed on the surface of the lamp source main board, and a movable rod passes through the limiting groove. A baffle is connected to one end of the movable rod, and a bracket is connected to the other end of the movable rod. A first bearing is installed between the bracket and the lamp source main board, and a driven bevel gear is connected to the surface of the bracket. A drive motor is installed on the side surface of the lamp source main board, and a drive bevel gear is connected to the output end of the drive motor.

[0013] When using the projection lamp of this technical solution, the drive motor can drive the active bevel gear to rotate. When the active bevel gear rotates, it drives the bracket to rotate through the driven bevel gear. When the bracket rotates, it can drive the baffle to rotate through the movable rod. When the baffle moves to one side of the lamp bead on the main board of the lamp source, it can block part of the lamp source. This allows for quick control of the light intensity according to the needs of the usage environment, avoiding excessive light that could damage the eyes of pedestrians.

[0014] Furthermore, four sets of limiting grooves, movable rods, and baffles are arranged in a circular array at the end of the bracket. The movable rod is slidably connected to the lamp source main board through the limiting groove. When the movable rod is subjected to force, it can slide inside the limiting groove, which can limit the movement direction of the movable rod.

[0015] Furthermore, the bracket forms a rotating structure with the lamp source mainboard through the first bearing.

[0016] Furthermore, the driving bevel gear and the driven bevel gear form a meshing structure. When the drive motor is running, it drives the driving bevel gear to rotate. When the driving bevel gear rotates, it drives the driven bevel gear to rotate through the meshing structure. When the driven bevel gear rotates, it can drive the bracket to rotate. This can realize the transmission between the drive motor and the bracket.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. In this utility model, when the knob drives the worm gear to rotate, it can drive the worm wheel to rotate. When the worm wheel rotates, it can drive the support leg to rotate. When the support leg rotates to the point where its end abuts against the outer surface of the insertion rod, the floodlight can be inserted into the ground through the insertion rod and then supported by the support leg, thereby maintaining the stability of the floodlight and preventing the floodlight from tipping over due to external forces.

[0020] 2. In this utility model, when the drive motor is running, it can drive the active bevel gear to rotate. When the active bevel gear rotates, it drives the bracket to rotate through the driven bevel gear. When the bracket rotates, it can drive the baffle to rotate through the movable rod. When the baffle moves to one side of the lamp bead on the main board of the lamp source, it can block part of the lamp source. In this way, the light intensity can be quickly controlled according to the needs of the usage environment, so as to avoid excessive light from damaging the eyes of pedestrians.

[0029] This specific embodiment is a projection lamp with an optical lens assembly, and its structural schematic diagram is shown below. Figures 1-5 As shown, the projection lamp includes a lens assembly 1, a rotating support 2, and a plug rod 3. The rotating support 2 is mounted on the surface of the lens assembly 1. The plug rod 3 is connected to the bottom side of the rotating support 2. A second bearing 4 is installed inside the plug rod 3. A worm gear 5 is connected through the inside of the second bearing 4. A knob 6 is connected to the top of the worm gear 5. A horizontal shaft 7 is connected to the side surface of the plug rod 3. The horizontal shaft 7 is connected through the inside of a third bearing 8. A worm wheel 9 is connected to the outer surface of the third bearing 8. A support leg 10 is connected to the surface of the worm wheel 9.

[0030] Among them, the worm 5 forms a rotating structure with the insert rod 3 through the second bearing 4. The horizontal shaft 7, the third bearing 8, the worm wheel 9 and the support leg 10 are arranged in a ring array in four groups on the outer surface of the insert rod 3. The worm wheel 9 forms a rotating structure with the horizontal shaft 7 through the third bearing 8. The worm 5 and the worm wheel 9 form a meshing structure.

[0031] A schematic diagram of an optical lens assembly is shown below. Figures 6-7As shown, the lens assembly includes a housing 101, a lens 102, and a lamp source main board 103. The lens 102 is connected inside the housing 101, and the lamp source main board 103 is installed inside the housing 101. A limiting groove 104 is formed on the surface of the lamp source main board 103, and a movable rod 105 passes through the limiting groove 104. A baffle 106 is connected to one end of the movable rod 105, and a bracket 107 is connected to the other end of the movable rod 105. A first bearing 108 is installed between the bracket 107 and the lamp source main board 103. A driven bevel gear 109 is connected to the surface of the bracket 107. A drive motor 110 is installed on the side surface of the lamp source main board 103, and a drive bevel gear 111 is connected to the output end of the drive motor 110.

[0032] The limiting groove 104, the movable rod 105 and the baffle 106 are arranged in a ring array at the end of the bracket 107. The movable rod 105 is slidably connected to the lamp source main board 103 through the limiting groove 104. The bracket 107 is rotatably connected to the lamp source main board 103 through the first bearing 108. The driving bevel gear 111 and the driven bevel gear 109 are meshed.

[0033] Working principle: When using the device of this technical solution, if the floodlight needs to be inserted into the ground, the knob 6 can be turned. When the knob 6 is turned, it can drive the worm 5 to rotate inside the second bearing 4. When the worm wheel 9 rotates, its helical surface is tightly meshed with the gear surface of the worm wheel 9, so that the worm wheel 9 rotates along the axis perpendicular to the worm 5.
