Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0028] Referring to Figures 1 - 6 as shown, in the embodiment of the present utility model, an adjustable-angle lamp is proposed, which includes a rear cover 1 and a lamp body 2 for emitting light. The lamp body 2 is a finished product, pre-produced, and has good protection performance. The main point is to install and fix it on different types of heavy-duty equipment through the rear cover 1. During installation, it needs to be adjusted according to the lighting direction. Specifically, an installation cavity 21 is provided on the lamp body 2, and a plurality of strip holes 22 evenly distributed along the circumferential direction are opened on the side wall of the installation cavity 21. The rear cover 1 is inserted into the installation cavity 21, and the outer wall of the rear cover 1 and the inner wall of the installation cavity 21 are concentric spherical surfaces. The rear cover 1 is provided with locking holes 11 corresponding to the strip holes 22. Three-dimensional angle adjustment can be achieved through the spherical surface cooperation between the outer wall of the rear cover 1 and the inner wall of the installation cavity 21. After the angle is adjusted according to the lighting direction, the adjusted angle needs to be locked.

[0029] Therefore, a fastening assembly 3 is further included. The fastening assembly 3 includes a pressing block 31 and a bolt 32. The bolt 32 passes through the pressing block 31, the strip hole 22 and is tightly connected to the locking hole 11. The pressing block 31 is pressed against the outer wall of the installation cavity 21 through the cooperation of the bolt 32 and the locking hole 11. The reliable locking is achieved by using the anti-slip effect of the pressing block 31, and there is no risk of the bolt 32 loosening in the case of heavy load. At the same time, the position of the lamp relative to the rear cover 1 can be adjusted by using the function of the strip hole 22, which increases the flexibility of angle adjustment and can maintain the angle after installation.

[0030] Meanwhile, a cable fixing head 4 is provided on the rear cover 1, and an avoidance notch 34 for avoiding the cable fixing head 4 is provided on the side wall of the installation cavity 21. The cable is fixed by the cable fixing head 4, so that the connection between the wiring terminal of the lamp body 2 and the external control module is not affected by the wiring after the angle adjustment.

[0031] To further stop the bolt 32 and prevent it from loosening, specifically, the fastening assembly 3 includes a stop washer 33. The stop washer 33 includes a flat washer portion 331 pressed between the bolt 32 and the pressing block 31. One end of the flat washer portion 331 is vertically bent to one side to form a first limiting portion 332, and the other end is vertically bent to the other side to form a second limiting portion 333. A limiting notch 15 cooperating with the first limiting portion 332 is provided on the rear cover 1. The side surface of the pressing block 31 abuts against the first limiting portion 332. The first limiting portion 332 is used for stopping in the limiting notch 15, and the angle of the pressing block 31 is limited to a certain extent. When the bolt 32 is locked, the second limiting portion 333 is bent to limit the rotation of the bolt 32, so that the bolt 32 will not loosen, and thus it will not loosen even under heavy load.

[0032] Meanwhile, anti-slip teeth 310 are provided on the surface of the pressing block 31 in contact with the side wall of the installation cavity 21. The anti-slip function is realized through the anti-slip teeth 310 to avoid the situation of the pressing block 31 sliding.

[0033] Specifically, the extending direction of the strip-shaped hole 22 is parallel to the axis of the installation cavity 21. Scale lines 5 are provided on the outer side wall of the installation cavity 21 on both sides of the strip-shaped hole 22. Marking lines are provided at both ends of the pressing block 31. Based on the direction limitation of the pressing block 31 by the stop washer 33, when adjusting the relative angle and position, the specific adjustment state can be known by comparing the marking lines on the pressing block 31 with the scale lines 5.

[0034] Specifically, to facilitate the connection of the lamp body 2 and internal heat dissipation, the rear cover 1 is of a cylindrical structure. A plurality of through holes 12 evenly distributed in the circumferential direction are provided on the side wall of the rear cover 1, and mounting holes 13 evenly distributed in the circumferential direction are provided on the bottom surface of the rear cover 1. The through holes 12 are used to dissipate the internal heat to the outside, and the mounting holes 13 are used to pre-fix the rear cover 1 on the heavy-duty equipment and then install the lamp body 2.

[0035] Meanwhile, reinforcing ribs 14 corresponding to the mounting holes 13 and the locking holes 11 are provided on the inner wall of the rear cover 1. The reinforcing ribs 14 are provided at the parts that need to be connected to improve the installation stability.

[0036] During the operation of the lamp body 2, heat dissipation is required. A radiator is integrated in the lamp body 2. The heat dissipation part of the radiator is located in the installation cavity 21, and the heat is dissipated to the outside through the installation cavity 21 and the through hole 12 by the radiator.
