Referring to fig. 1 and 2, a light projector includes: the back shell 10 is internally provided with an open cavity; the light-transmitting plate 20 is arranged on the back shell 10 and seals the cavity; at least one locking clip 40, including a plurality of clamping portions that can approach or separate from each other, the plurality of clamping portions being respectively disposed on the back shell 10 and the light-transmitting plate 20, and the two clamping portions being capable of clamping the back shell 10 and the light-transmitting plate 20; a protrusion 41 provided on the locking clip 40; and a bracket 30 hinged to the extension 41 for supporting the back case 10. The bracket 30 is hinged to the extension 41, not disposed on the back shell 10, so that the back shell 10 does not need to be perforated and the bolt 61 is inserted, thereby preventing moisture from entering the back shell 10 from the perforated part of the back shell 10 and ensuring the waterproof effect of the lamp body.

Preferably, referring to fig. 1, the light-transmitting plate 20 is divided into a light-transmitting area 21 and a non-light-transmitting area 22. The transparent region 21 is made of transparent material, and light can be exposed from the transparent region 21 to the outside. The opaque region 22 is coated with a coating so that light cannot pass through the opaque region 22. By dividing the light-transmitting area 21 and the non-light-transmitting area 22, light is more dense, thereby improving the lighting effect.

Further, referring to fig. 6, an LED lamp panel 13 and a reflective cup 12 for emitting light are further disposed in the back panel. The two ends of the reflective cup 12 are respectively connected with the LED lamp panel 13 and the light-transmitting area 21.

Preferably, referring to fig. 3 and 4, locking clips 40 are provided at opposite sides of the back shell 10; the bracket 30 is a U-shaped bracket 30, and both ends of the bracket 30 are hinged to the extending portions 41 on both sides of the back shell 10. The extension 41 extends toward the bottom of the back case 10, so that the bracket 30 is biased more toward the bottom of the back case 10, thereby supporting the back case 10 from this direction.

Preferably, referring to fig. 5, a through hole 42 is formed on each of the bracket 30 and the extension 41, a bolt 61 is movably installed in the through hole 42, and a nut 62 is further fittingly connected to an end of the bolt 61. The bracket 30 and the extension 41 are both sleeved on the periphery of the bolt 61. The through hole 42 is in clearance fit with the bolt 61, so that the bracket 30 and the extension 41 can rotate relatively, thereby adjusting the supporting angle of the bracket 30 to the back shell 10.

Preferably, referring to fig. 4, the nut 62 is further provided with a locking structure for preventing the nut 62 from falling off the bolt 61. Because relative rotation is required between the bracket 30 and the back shell 10, the bolt 61 may be rotated by the bracket 30 under the action of friction, so that the nut 62 is disengaged from the bolt 61. The anti-loosening structure can prevent the nut 62 from being separated from the bolt 61, thereby ensuring safety and stable overall operation.

Preferably, referring to fig. 4, the anti-loose structure includes a rubber ring 63 disposed between the nut 62 and the bolt 61. The rubber ring 63 is closely disposed at the edge of the nut 62 and tightens the bolt 61. When relative rotation takes place between bolt 61 and the nut 62, rubber ring 63 will produce relative friction with nut 62 to prevent to take place relative rotation between nut 62 and the bolt 61, guarantee the stability that the projecting lamp used.

Preferably, the anti-loosening structure may also be a locking key (not shown) and a locking key groove (not shown) disposed between the nut 62 and the bolt 61. When relative rotation occurs between the nut 62 and the bolt 61, relative collision interference occurs between the stopper key and the stopper key groove, thereby preventing relative rotation between the nut 62 and the bolt 61.

Preferably, referring to fig. 2 and 5, the back shell 10 is further provided with a locking structure for preventing the locking clip 40 from falling off between the back shell 10 and the light-transmitting plate 20. In the process of moving the projector, the projector needs to be moved. The locking clip 40 is easily released from the back shell 10 during movement. The anti-dropping structure can prevent the locking clamp 40 from dropping, thereby ensuring the stability of the whole body.

Preferably, referring to fig. 2 and 5, the anti-dropping structure comprises a bar-shaped boss 50 arranged on the back shell 10, and two ends of the bar-shaped boss 50 are provided with separating gears 51; the locking clamp 40 is provided with a strip-shaped groove 43 which is matched and connected with the strip-shaped boss 50. The strip-shaped ribs and the strip-shaped grooves 43 cooperate with each other to fasten the locking clip 40. The strip shape increases the contact area between the two, and the blocking position 51 can prevent the two from moving relatively away from the two ends of the strip-shaped convex strip.

Further, referring to fig. 2, a protrusion is disposed on the blocking portion 51, and the height of the protrusion is higher than that of the bar-shaped protrusion 50.

Preferably, referring to fig. 3, the bar-shaped bosses 50 have curved sidewalls. The curved side wall can enable the contact between the two or the relative distance between the two to be smoother, so that the difficulty in disassembly is reduced.

Preferably, the anti-separation structure may also be a hook (not shown) disposed on the locking clip 40 and a groove (not shown) disposed on the back shell 10. The hook is fitted in the catching groove so that the locking clip 40 and the back shell 10 do not move relatively.

Preferably, referring to fig. 6, the back case 10 is provided at the opening with a step 11 inside the back case 10, and the light-transmitting plate 20 rests on the step 11. The recessed step 11 allows the light-transmitting plate 20 to be mounted on the back case 10 in a recessed manner. Thus, the whole is integrated more, the appearance is improved, and the protruded corners of the light transmission plate 20 can be reduced, so that the damage of the light transmission plate 20 is reduced.

Preferably, the inner wall of the back shell 10 and the side wall of the light-transmitting plate 20 are fixed and sealed by glue. The glue filling form not only can enable the matching of the glue filling form and the glue filling form to be more compact, but also can enable moisture not to permeate from the gap between the glue filling form and the glue filling form, so that the waterproof effect is improved.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments or combinations, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
