Description

Technical Field

[0001] This utility model relates to the field of LED projection lamp technology, and in particular to an LED projection lamp with a shockproof structure. Background Technology

[0002] LED projector lights are devices used to project images onto a screen or other background for display. They are widely used in people's lives and work. An LED projector light has an internal optical lens that projects the light emitted by the LEDs on the LED panel onto the screen. Currently, an LED projector light body rotates on a mounting base, which is fixed to a wall or mounting frame. The connection between the mounting base and the projector body is secured using damping shims and screws. During use, vibrations from the mounting frame or other sources are transmitted to the mounting base, causing the projector body to shake. Prolonged vibration can lead to wear on the shims and loosening of the screws at the connection point, further loosening the fixation and increasing the projector body's sway. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an LED projection lamp with a shockproof structure, so as to solve the problems of wear and tear of the gasket and the lamp body at the connection between the mounting base and the lamp body and loosening of the screw when the mounting base and the lamp body are subjected to vibration for a long time, which makes the fixation of the lamp body loose and increases the shaking of the lamp body.

[0004] In view of this, the present invention provides an LED projection lamp with a shockproof structure, including a base, on which a lamp body is rotatably mounted, and a fixing mechanism is provided on the base;

[0005] The fixing mechanism includes a first mounting plate, a plurality of movable columns, a second mounting plate, a plurality of movable cylinders, a plurality of mounting cylinders, a locking screw, and a support member. The first mounting plate is disposed on both sides of the base. The plurality of movable columns are fixedly installed on one end of the first mounting plate. The plurality of movable cylinders are fixedly installed on the second mounting plate. The movable cylinders are slidably installed on the outer wall of the corresponding movable column. The plurality of mounting cylinders are fixedly installed on both sides of the base. The locking screw is threadedly connected to the inner wall of the mounting cylinder. The support member is fixedly installed on one end of the locking screw.

[0006] Optionally, the support member is located between the corresponding first mounting plate and second mounting plate, and a knob is fixedly installed at the other end of the locking screw.

[0007] Optionally, the second mounting plate is slidably mounted to one end of the first mounting plate via the movable cylinder thereon.

[0008] Optionally, the first mounting plate and the second mounting plate have a plurality of mounting grooves at one end, and a plurality of locking posts are fixedly installed on one side and the bottom of the mounting groove, and a gasket is installed inside the mounting groove.

[0009] Optionally, a plurality of engaging grooves are provided at the bottom of one end of the gasket, and the engaging grooves engage with the corresponding engaging posts.

[0010] Optionally, mounting shafts are fixedly installed on both sides of the lamp body, and a fixing plate is fixedly installed at one end of the mounting shaft extending to the outside of the base. The first mounting plate and the second mounting plate are installed on the outer wall of the mounting shaft.

[0011] Optionally, a mounting bracket is fixedly installed on the base, and the first mounting plate and the second mounting plate are located between one side of the base and the mounting plate.

[0012] As can be seen from the above technical solutions, the embodiments of this utility model have the following advantages:

[0013] 1. This utility model discloses an LED projection lamp with a shockproof structure. By setting up an installation mechanism, the support member supports the first mounting plate, which presses the pads on the first mounting plate against one end of the fixed plate, and the support member supports the second mounting plate, which presses the pads on one side of the base to fix the mounting shaft. This can increase the fixing effect at the connection between the lamp body and the base. By the support member opening the first and second mounting plates, the locking screw can be loosened to a small extent without affecting the fixing effect at the connection between the lamp body and the base. This reduces the impact of vibration on the connection between the lamp body and the base and plays a good role in shockproofing.

[0014] 2. The LED projection lamp with shockproof structure of this utility model has a detachable gasket that is fixed to the corresponding first mounting plate and second mounting plate by a snap-fit ​​method, which facilitates the replacement of worn gaskets.

[0015] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0022] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0023] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: an LED projection lamp with a shockproof structure.

[0024] Example 1

[0025] For easier understanding, please refer to Figures 1 to 4 This utility model provides an embodiment of an LED projection lamp with a shockproof structure, including a base 1, a lamp body 3 rotatably mounted on the base 1, and a fixing mechanism provided on the base 1; the fixing mechanism includes a first mounting plate 13, a plurality of movable columns 14, a second mounting plate 15, a plurality of movable cylinders 16, a plurality of mounting cylinders 6, a locking screw 7, and a support member 8. The first mounting plate 13 is disposed on both sides of the base 1, the plurality of movable columns 14 are fixedly mounted on one end of the first mounting plate 13, the plurality of movable cylinders 16 are fixedly mounted on the second mounting plate 15, the movable cylinders 16 are slidably mounted on the outer wall of the corresponding movable column 14, the plurality of mounting cylinders 6 are fixedly mounted on both sides of the base 1, the locking screw 7 is threadedly connected to the inner wall of the mounting cylinder 6, and the support member 8 is fixedly mounted on one end of the locking screw 7.

[0026] It should be noted that by setting up the installation mechanism, the first mounting plate 13 and the second mounting plate 15 are set on the mounting shafts 4 on both sides of the base 1. Rotating the locking screw 7 causes the locking screw 7 to rotate and move in the mounting cylinder 6, driving the support member 8 to move. When the support member 8 moves between the first mounting plate 13 and the second mounting plate 15, the shim 10 on the first mounting plate 13 is pressed against one end of the fixing plate 5 from the middle, and the shim 10 on the second mounting plate 15 is pressed against one side of the base 1, fixing the mounting shaft 4. This can increase the fixing effect at the connection between the lamp body 3 and the base 1. By using the support member 8 to open the first mounting plate 13 and the second mounting plate 15, the locking screw 7 can be loosened to a small extent without affecting the fixing effect at the connection between the lamp body 3 and the base 1, reducing the impact of vibration on the connection between the lamp body 3 and the base 1, and playing a good anti-vibration role. The inner wall of the mounting cylinder 6 is provided with internal threads, and the locking screw 7 is connected to the mounting cylinder 6 through the internal threads.

[0027] In some embodiments, such as Figure 2 As shown, the support member 8 is located between the corresponding first mounting plate 13 and second mounting plate 15. A knob 9 is fixedly installed at the other end of the locking screw 7. The second mounting plate 15 is slidably mounted on one end of the first mounting plate 13 via the movable cylinder 16 on it.

[0028] It should be noted that the first mounting plate 13 and the second mounting plate 15 are connected by the movable column 14 and the movable cylinder 16, so that the distance between the first mounting plate 13 and the second mounting plate 15 can be adjusted by pulling or pressing, so that the first mounting plate 13 moves away from or closer to the second mounting plate 15.

[0029] In this example, when the support 8 is far away from the first mounting plate 13 and the second mounting plate 15, the fixing of the mounting shaft 4 is removed, so that the lamp body 3 can rotate normally.

[0030] In some embodiments, such as Figure 3 As shown, the first mounting plate 13 and the second mounting plate 15 have several mounting grooves 11 at one end. Several locking posts 12 are fixedly installed on one side and bottom of the mounting groove 11. A gasket 10 is installed inside the mounting groove 11. Several engaging grooves are opened at the bottom of one end of the gasket 10. The engaging grooves engage with the corresponding locking posts 12.

[0031] It should be noted that the gasket 10 is designed to be detachable and is fixed to the corresponding first mounting plate 13 and second mounting plate 15 by snap-fit, which facilitates the replacement of worn gasket 10.

[0032] In this example, gasket 10 can be a rubber gasket.

[0033] Example 2

[0034] In some embodiments, such as Figure 1, Figure 2 As shown, mounting shafts 4 are fixedly installed on both sides of the lamp body 3. A fixing plate 5 is fixedly installed at one end of the mounting shaft 4 that extends to the outside of the base 1. The first mounting plate 13 and the second mounting plate 15 are installed on the outer wall of the mounting shaft 4. A fixing bracket 2 is fixedly installed on the base 1. The first mounting plate 13 and the second mounting plate 15 are located between one side of the base 1 and the fixing plate 5.

[0035] It should be noted that the lamp body 3 is rotatably mounted on the base 1 via the mounting shaft 4.

[0036] In this example, at least three movable columns 14 and movable cylinders 16 are engaged with the outer wall of the mounting shaft 4, so that the first mounting plate 13 and the second mounting plate 15 are mounted on the outer wall of the mounting shaft 4.

[0037] In this example, the lamp body 3 can be an existing LED projection lamp.

[0038] In this example, the heat dissipation mechanism inside the lamp body 3 can use heat dissipation fins to conduct heat to the outer shell of the lamp body 3 for dissipation.

[0039] Working principle: The lamp body 3 contains a circuit board, lens, and heat dissipation mechanism. An LED light board is installed on the circuit board. The LED light board emits light through the light-emitting diodes on it to form a pattern. The light is refracted by several lenses and projected onto a screen or wall from the transparent light board at one end of the lamp body 3.

[0040] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
