DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0031] Example 1

[0032] The present invention provides an outdoor LED wall lamp, such as Figures 1 to 10 As shown, it includes an outer wall lamp body 1, the outer surface of the outer wall lamp body 1 is slidably connected with a connecting shell 2, the top of the outer wall lamp body 1 is installed with the connecting shell 2, the connecting shell 2 can be connected with the upper lamp shell 3 by snapping, and the upper lamp shell 3 is installed with a rain shield mechanism 4 inside;

[0033] The rainproof mechanism 4 includes a rotating disk 41 rotatably connected to the bottom end of the upper lamp housing 3, an internal gear 42 is fixedly connected to the inside of the rotating disk 41, a first gear 43 is meshingly connected to the surface of the internal gear 42, a second gear 44 is meshingly connected to the surface of the first gear 43, a circular disk 45 is fixedly connected to the top of the second gear 44, an expansion mechanism 5 is slidably connected to the top of the circular disk 45, a waterproof cloth 46 is snap-connected at the edge of the expansion mechanism 5, the waterproof cloth 46 is made of elastic rubber material, which is convenient for stretching and deformation and can automatically restore when there is no external force, a mounting column 47 is arranged inside the waterproof cloth 46, the mounting column 47 is fixedly connected to the top end of the upper lamp housing 3, a cloth baffle 48 is fixedly connected to the bottom end of the mounting column 47, and the cloth baffle 48 is located below the waterproof cloth 46, an annular block 49 is slidably connected to the surface of the mounting column 47, a positioning spring 411 is fixedly connected to the bottom end of the annular block 49, and the positioning spring 411 is sleeved on the surface of the mounting column 47.

[0034] like Figure 2 , Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, four arc-shaped grooves are opened inside the circular disk 45, and the four arc-shaped grooves are distributed in a circular array with the center of the top surface of the circular disk 45 as the center of the circle;

[0035] The expansion mechanism 5 includes a slider 51 slidably connected to the top of the circular disk 45, and a positioning protrusion 52 slidably connected to the inside of the arc groove is fixedly connected to the bottom of the slider 51. The number of sliders 51 is set to four, and arc-shaped limit baffles 53 are fixedly connected to the surfaces of three sliders 51. The waterproof cloth 46 is connected to the inside of the arc-shaped limit baffle 53 by snapping. The bottom end of the cloth baffle 48 is fixedly connected to the limit plate, and the limit plate is located on both sides of the slider 51. Figure 5 As shown, when the circular disk 45 rotates, it drives the positioning protrusion 52 to slide. At this time, the positioning protrusion 52 slides toward the edge of the circular disk 45 and drives the slider 51 to move toward the outside of the upper lamp housing 3. The slider 51 drives the arc-shaped limit baffle 53 to move. The movement of the arc-shaped limit baffle 53 drives the waterproof cloth 46 to open, so that the waterproof cloth 46 forms a rainproof barrier, thereby preventing rainwater from entering the interior of the outer wall lamp body 1, which affects the lighting effect of the LED outer wall lamp.

[0036] like Figure 7 and Fig.10As shown, the surface of another slider 51 is hingedly connected to two expansion blocks 54, and the angle surfaces of the two expansion blocks 54 are fixedly connected with an arc spring 55, and the arc spring 55 is located between the two expansion blocks 54. One end surfaces of the two expansion blocks 54 are respectively rotatably connected to the surfaces of two adjacent arc-shaped limit baffles 53, and the two expansion blocks 54 form an angle. When the slider 51 moves, it will drive the two expansion blocks 54 to move synchronously, and through the action of the arc spring 55, the two expansion blocks 54 are expanded and the waterproof cloth 46 is driven to expand. At this time, the slider 51 drives the two expanded expansion blocks 54 to move until they fit with the wall and stop moving. The fit of the waterproof cloth 46 with the wall prevents rainwater from flowing through the wall to the surface of the mounting seat 6, causing the screws inside the mounting seat 6 to rust, thereby avoiding the problem of rusty screws shaking, thereby improving the stability of the mounting seat 6 installed on the wall.

[0037] like Figures 1 to 3 As shown, a mounting seat 6 is fixedly connected to the surface of the connecting shell 2, a slide plate 7 is slidably connected to the inside of the mounting seat 6, a connecting plate 8 is fixedly connected to the bottom edge of the slide plate 7, a mounting shell 9 is fixedly connected to the bottom end of the connecting plate 8, a side surface of the bottom end of the connecting plate 8 is mounted to the mounting shell 9 through a protrusion, an L shape is formed between the slide plate 7, the connecting plate 8 and the protrusion, the slide plate 7, the connecting plate 8 and the protrusion are mounted inside the mounting seat 6, at this time the slide plate 7 can drive the mounting shell 9 to rise or fall, at this time the overall structure of the mounting seat 6 is not changed, thereby avoiding the problem of deformation of the mounting seat 6 caused by the instability of the overall structure of the mounting seat 6.

[0038] like Figure 3 , Figure 4 and Figure 8 As shown, a motor 10 is installed at the inner bottom end of the mounting seat 6, and a screw rod 11 is fixedly connected to the output end of the motor 10. The screw rod 11 is connected to the slide plate 7 by a threaded connection. The rotation of the screw rod 11 is connected to the inner top end of the mounting seat 6. The motor 10 can rotate in both directions. The outer side surface of the slide plate 7 fits with the inner wall of the mounting seat 6. When the motor 10 is started to rotate forward, the motor 10 drives the screw rod 11 to rotate. At this time, the slide plate 7 moves downward along the surface of the rotating screw rod 11. Since the outer surface of the slide plate 7 fits with the inner wall of the mounting seat 6, the slide plate 7 will not deviate when it moves downward, thereby improving the stability of the slide plate 7 when it moves.

[0039] like Figure 3 , Figure 6 and Figure 8As shown, a clamping block 12 is slidably connected at the internal top position of the connecting shell 2, and a clamping block 2 13 is embedded and installed at the bottom end of the upper lamp shell 3. The clamping block 12 and the clamping block 2 13 are both composed of a number of rectangular blocks of the same size. The rectangular blocks on the surface of the clamping block 12 and the rectangular blocks on the surface of the clamping block 2 13 are staggered, and inclined surfaces are provided on both sides of the rectangular blocks. When the positions of the clamping block 12 and the clamping block 2 13 are slightly offset, it does not affect the clamping of the clamping block 12 and the clamping block 2 13, so that the clamping block 12 and the clamping block 2 13 can be smoothly clamped.

[0040] like Figure 3 , Figure 8 and Fig. 9 As shown, a spring assembly 14 is rotatably connected at a position below the clamping block 12, and an arc plate 141 is provided at the top and bottom of the spring assembly 14. The arc plate 141 at the bottom is fixedly connected to the inside of the connecting shell 2, and the arc plate 141 at the top is slidably connected to the bottom end of the clamping block 12. A spiral plate 15 is fixedly connected to the inside of the connecting shell 2, and an arc block 16 is slidably connected to the inside of the spiral plate 15. The arc block 16 is fixedly connected to the bottom end of the clamping block 12, and a ball 17 is rotatably connected to the bottom end of the inner part of the arc block 16. A guide groove is provided inside the spiral plate 15, and the shape of the guide groove is spiral, and a circular groove is provided inside the guide groove. The arc block 16 slides inside the guide groove, and the ball 17 slides inside the circular groove. When the clamping block 12 moves downward, it drives the arc block 16 and the ball 17 to move downward, and slide inside the guide groove and the circular groove, and drives the arc block 16 and the ball 17 to rotate. At this time, the waterproof cloth 46 is opened. When the clamping block 2 13 moves upward, the spring assembly 14 drives the clamping block 12 to rise together. When the clamping block 12 rises, it drives the ball 17 to rotate in the opposite direction along the circular groove. At this time, the clamping block 12 drives the clamping block 2 13 to reset, and then completes the opening and recovery of the waterproof cloth 46, thereby automating the process of opening and recovering the waterproof cloth 46.

[0041] like Figure 6 As shown, a rotating column 18 is fixedly connected to the middle position of the bottom end of the mounting column 47, the rotating column 18 passes through the interior of the second gear 44 and the circular disk 45 and is fixedly connected to the bottom end of the upper lamp housing 3. When the second gear 44 drives the circular disk 45 to rotate, it rotates on the surface of the rotating column 18. At this time, the rotation process of the second gear 44 will not affect the rotation of the upper lamp housing 3, thereby improving the stability of the upper lamp housing 3.

[0042] like Figure 3 , Figure 4 , Figure 8 and Fig. 9As shown, the mounting shell 9 is fixedly mounted on the surface of the outer wall lamp body 1, and the mounting shell 9 is sleeved and connected to the inside of the connecting shell 2. A slot is provided on the surface of the connecting shell 2 on one side of the mounting seat 6, and the protrusion is slidably connected to the inside of the slot, so that the entire mounting shell 9 can be hidden, thereby avoiding the mounting shell 9 blocking the luminous effect of the outer wall lamp body 1.

[0043] Working principle: When the device is in use, the staff starts the motor 10, and the motor 10 drives the screw rod 11 to rotate. Under the limiting effect of the mounting seat 6, the slide plate 7 outside the screw rod 11 can move vertically downward along the inner wall of the mounting seat 6, and the slide plate 7 drives the connecting plate 8 to move downward, and the connecting plate 8 drives the mounting shell 9 to move downward, and the mounting shell 9 drives the outer wall lamp body 1 to move downward, and the outer wall lamp body 1 drives the upper lamp shell 3 to move downward. When the bottom end surface of the upper lamp shell 3 is close to the top end surface of the connecting shell 2, the rectangular blocks of the clamping block 12 and the clamping block 2 13 are staggered and clamped along the inclined surface of the surface, and then the clamping block The second 13 drives the clamping block 12 to move downward, and the clamping block 12 moves downward to drive the arc block 16 to move downward, and the arc block 16 moves downward to drive the ball 17 to move downward. At this time, when the arc block 16 and the ball 17 move downward, they slide along the guide groove and the circular groove inside the spiral plate 15, and then the arc block 16 and the ball 17 rotate along the inside of the guide groove and the circular groove. At this time, the arc block 16 rotates to drive the clamping block 12 to rotate. During the process of the clamping block 12 rotating and moving downward, the clamping block 12 presses down the arc plate 141 at the top of the spring assembly 14, so that the spring assembly When the first clamping block 12 and the second clamping block 13 rotate synchronously, the second clamping block 13 drives the rotating disk 41 to rotate, the rotating disk 41 drives the internal gear 42 to rotate, the internal gear 42 drives the first gear 43 to rotate, the first gear 43 drives the second gear 44 to rotate, the second gear 44 drives the circular disk 45 to rotate, and the circular disk 45 drives the positioning protrusion 52 to slide along the arc groove toward the edge of the circular disk 45. At this time, when the positioning protrusion 52 slides, it drives the slider 51 to slide outward, and when the slider 51 slides, it slides inside the limit plate, so that when the slider 51 slides, The slider 51 is guided by the limit plate to slide in the horizontal direction. When the slider 51 slides and drives the arc-shaped limit baffle 53 to slide, the arc-shaped limit baffle 53 slides toward the outer side of the upper lamp housing 3 and drives the waterproof cloth 46 to expand. When the waterproof cloth 46 expands, it drives the annular block 49 to move downward on the surface of the mounting column 47 and squeezes the positioning spring 411. At this time, the annular block 49 descends to make the waterproof cloth 46 expand outward to form a rainproof barrier, thereby preventing rainwater from entering the interior of the outer wall lamp body 1, which affects the lighting effect of the LED outer wall lamp.

[0044] Then, when the slider 51 slides toward the outer side of the upper lamp housing 3, the two expansion blocks 54 are driven to slide, and the sliding of the expansion blocks 54 drives the arc spring 55 to slide. At this time, the expansion block 54 slides to a part of the outer side of the upper lamp housing 3, and the arc spring 55 expands the angle of the two expansion blocks 54 under the action of elastic force. The two expansion blocks 54 drive the internal waterproof cloth 46 to be straightened, so that the waterproof cloth 46 is in linear contact with the wall, thereby preventing rainwater from flowing through the wall to the surface of the mounting seat 6, causing the screws inside the mounting seat 6 to rust, and avoiding the problem of rusty screws shaking, thereby improving the stability of the mounting seat 6 installed on the wall.

[0045] Finally, while waiting for the rain to stop, the staff starts the motor 10 in reverse and reverses the above steps to retract the waterproof cloth 46 into the interior of the upper lamp shell 3. The positioning spring 411 drives the waterproof cloth 46 to rise, so that the overall shape of the waterproof cloth 46 is an inverted cone, and the excess waterproof cloth 46 falls on the surface of the cloth baffle 48 to prevent the waterproof cloth 46 from directly contacting the expansion mechanism 5. At this time, the waterproof cloth 46 is completely recovered into the interior of the upper lamp shell 3, thereby preventing the waterproof cloth 46 from being exposed to the outside of the upper lamp shell 3, causing the waterproof cloth 46 to be exposed to the sun, thereby improving the service life of the waterproof cloth 46.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
