DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

[0050] Embodiment 1

[0051] Reference Figures 1-3The utility model provides a waterproof spotlight, which is applied in the field of lighting, the spotlight mainly includes base 1, the upper rotatory connection of base 1 has lamp house 5. Base 1 is used for supporting and fixing the whole spotlight, and lamp house 5 is used for accommodating and protecting the internal optical assembly. On the outer wall of lamp house 5, two symmetrical semicircular rings 17 are fixed by bolt. The bottom of the two semicircular rings 17 is fixed with a connecting lug 18 respectively. The top of base 1 is provided with a lead screw 20, and the lead screw 20 is connected with the connecting lug 18, and the lamp house 5 can be driven to rotate around its axis by rotating the lead screw 20. This design makes the angle adjustment of lamp house 5 simple and accurate.

[0052] With reference to Figure 3 and Figure 4 , inside lamp house 5, LED lamp plate 9 and lens assembly 10 are arranged. LED lamp plate 9 serves as a light source to provide light required for lighting, and lens assembly 10 focuses and distributes light to achieve the desired lighting effect.

[0053] With reference to Figure 5 , an arc-shaped sliding groove 25 is arranged in base 1, and an arc-shaped plate 26 is slidably connected in the sliding groove. The two ends of arc-shaped plate 26 are fixedly connected with the bottom of lamp house 5. This design not only provides stable support for lamp house 5, but also allows lamp house 5 to remain stable during rotation.

[0054] With reference to Figure 5 , an outer ring groove 43 is arranged on the top of base 1, and the outer ring groove 43 is in communication with a plurality of countersunk holes 44 in the interior of base 1. A fastening bolt 45 is arranged in the countersunk hole 44, and by tightening the fastening bolt 45, base 1 can be firmly fixed on the mounting surface to ensure the stability of the spotlight.

[0055] With reference to Figure 3 and Figure 4 , in order to prevent water from entering the interior of lamp house 5, the utility model adopts the following waterproof structure: a first mounting groove 11 is formed at one end of lamp house 5, and a light-transmitting assembly is mounted in the groove. The light-transmitting assembly is composed of two first transparent glass plates 14 and a third sealing ring 15 clamped between the two first transparent glass plates 14. A first sealing ring 12 is fixed on the inner wall of one side of first mounting groove 11, and one end of the light-transmitting assembly is tightly fitted with the first sealing ring 12; the other end is tightly fitted with first mounting groove 11 through a second sealing ring 13. This multiple sealing structure effectively improves the waterproof performance of lamp house 5.

[0056] With reference to Figure 1 , Figure 2 , Figure 5 and Figure 6, the adjusting structure is mainly composed of a rotating cylinder 19, a screw rod 20, a connecting head 21, a fixing pin 22, a base 2, a rotating shaft 3, a connecting arm 4, an angle disc 23 and an indicating needle 24. The rotating cylinder 19 is rotatably arranged on the top of the base 1, and the screw rod 20 is threadedly penetrated through the rotating cylinder 19 and can be lifted and lowered in the rotating cylinder 19. The top end of the screw rod 20 is fixed with the connecting head 21, and the fixing pin 22 is penetrated through the connecting head 21. The connecting ear 18 is sleeved on the fixing pin 22 and connected with the screw rod 20. When the rotating cylinder 19 is rotated, the screw rod 20 is lifted and lowered and drives the connecting ear 18 and the lamp shell 5 to rotate through the fixing pin 22. Meanwhile, the rotating shaft 3 is rotatably arranged in the base 2, the connecting arm 4 is fixedly sleeved on the outer wall of the rotating shaft 3, and the connecting arm 4 is welded on the bottom of the lamp shell 5. One end of the rotating shaft 3 extends to one side of the base 2 and is fixed with the angle disc 23, and one side of the base 2 is further fixed with the indicating needle 24 matched with the angle disc 23. The relative position of the indicating needle 24 and the angle disc 23 can be observed to accurately control the rotation angle of the lamp shell 5.

[0057] Through the above structural design and specific implementation, the waterproof spotlight convenient to adjust is realized. The spotlight not only has good waterproof performance but also can conveniently adjust the lighting angle to meet the lighting requirements of different occasions.

[0058] With reference to Figure 2 , Figure 5 , Figure 6 and Figure 7 , in order to realize convenient adjustment and braking of the rotating cylinder 19 and the screw rod 20, an annular groove 27 is designed on the top of the base 1. An outer gear ring 28 is slidably connected in the annular groove 27, and an annular sliding groove 29 is formed in the top of the outer gear ring 28. An fixing ring 30 is fixedly sleeved on the outer wall of the rotating cylinder 19, and an inner gear ring 31 is fixedly arranged on the bottom of the fixing ring 30. The inner gear ring 31 is engaged with the outer gear ring 28. In order to control the lifting of the outer gear ring 28, a screw rod 32 is threadedly penetrated in the fixing ring 30, the bottom end of the screw rod 32 extends into the inner gear ring 31, and a sliding block 33 is rotatably connected to the bottom end of the screw rod 32. The sliding block 33 is slidably arranged in the annular sliding groove 29, so that when the screw rod 32 is rotated, the outer gear ring 28 can be driven to move up and down by the sliding block 33.

[0059] Specifically, when the rotating cylinder 19 needs to be fixed, the screw rod 32 is rotated clockwise, the outer gear ring 28 is lifted and closely engaged with the inner gear ring 31, so that the rotating cylinder 19 is braked and prevented from being accidentally rotated. Conversely, when the angle of the lamp shell 5 needs to be adjusted, the screw rod 32 is rotated counterclockwise, the outer gear ring 28 is lowered and disengaged from the inner gear ring 31, so that the rotating cylinder 19 can be freely rotated to realize angle adjustment.

[0060] With reference to Figure 1 , Figure 2 , Figure 5And Figure 6 In order to further ensure the stability of the lamp shell 5, a circular groove 40 is designed at the bottom of the base 1, and the arc-shaped plate 26 penetrates through the circular groove 40. A rubber friction plate 39 is slidably connected in the circular groove 40, which is used to brake the arc-shaped plate 26. At the same time, a transmission groove 34 is arranged in the base 1 and communicates with the circular groove 40, and a moving plate 35 is slidably connected in the transmission groove 34. The top of the moving plate 35 is rotatably connected with a plurality of second connecting rods 38, and the top ends of the second connecting rods 38 are rotatably connected with the bottom of the rubber friction plate 39.

[0061] Referring to Figure 1 , Figure 2 , Figure 5 And Figure 6 The bottom of the outer tooth ring 28 is fixed with a vertical rod 36, the bottom end of the vertical rod 36 slidably extends into the transmission groove 34, and is rotatably connected with a first connecting rod 37. The bottom end of the first connecting rod 37 is rotatably connected with the top of the moving plate 35.

[0062] Specifically, when the outer tooth ring 28 rises, the moving plate 35 is driven to move to the left side through the cooperation of the vertical rod 36 and the first connecting rod 37. The movement of the moving plate 35 drives the rubber friction plate 39 to move up through the second connecting rod 38, realizes the braking of the arc-shaped plate 26, and further stabilizes the lamp shell 5. Conversely, when the outer tooth ring 28 descends, the rubber friction plate 39 also descends, thereby releasing the braking of the arc-shaped plate 26, and facilitating the angle adjustment of the lamp shell 5.

[0063] Referring to Figures 2-4 The lens assembly 10 is firmly fixed inside the lamp shell 5 by bolts. In the lamp shell 5, an installation frame 7 is also fixed, and the side of the installation frame 7 away from the lens assembly 10 is fixed with an installation plate 8 by bolts. The LED lamp plate 9 is embedded on the side of the installation plate 8 close to the lens assembly 10, so as to ensure that the light can be uniformly emitted through the lens assembly 10.

[0064] Referring to Figure 2 , Figure 3 And Figure 5 The end of the lamp shell 5 away from the first installation groove 11 is fixed with a rear cover 6 for closing the lamp shell 5 and protecting the internal elements. At the same time, the bottom of the lamp shell 5 is fixed with a wiring tube 41 for protecting the power line of the LED lamp plate 9 from being damaged. The arc-shaped plate 26 is also provided with a wiring hole 42 to facilitate the guidance and fixation of the power line, and to ensure the safety and reliability of the electrical connection of the entire projection lamp.

[0065] Referring to Figure 4First, a fixed ring 16 is fixedly installed on the outer wall of the lamp shell 5, which is matched in size and shape with the outer diameter of the lamp shell 5 to ensure stable installation. Then, two semicircular rings 17 are prepared, and the inner edges of the two semicircular rings 17 are designed with grooves matched in size and shape with the outer contour of the fixed ring 16 to realize accurate positioning of the semicircular rings 17.

[0066] Specifically, when the two semicircular rings 17 are installed on the lamp shell 5, they are first sleeved on the fixed ring 16 through the grooves, and then fastened and connected through bolts passing through the reserved holes on the semicircular rings 17 and the corresponding holes on the fixed ring 16, thereby completing the fixed installation of the semicircular rings 17. This design not only facilitates the positioning and installation of the semicircular rings 17, but also ensures the stability of the installation.

[0067] The lens assembly 10 is the same product as the lens assembly in the invention with publication number CN104930401B.
