[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, an embodiment of this application provides a sealed adjustable reflector device, which includes a reflector base 1, a lens mounting base 2, a lens 3, and a lens cover 4 in sequence. The lens mounting base 2 is provided with a through hole 21 for accommodating the top of the lens 3 and the lens cover 4. The lens cover 4 is installed on the through hole 21 of the lens mounting base 2. The lens 3 is attached to the top of the lens cover 4 and located in the through hole 21 of the lens mounting base 2. The lens mounting base 2 is connected to the reflector base 1 through an adjustment component 5.

[0025] like Figure 2 As shown, the adjustment assembly 5 includes a steel ball 51, an adjustment block 52, a round pad 53, two threaded pairs 54, and several spring assemblies 55. The steel ball 51, the adjustment block 52, and the round pad 53 are respectively installed on the three end corners of the reflector mount 1. The round pad 53 is symmetrically arranged with the adjustment block 52. The two threaded pairs 54 are symmetrically installed on the lens mounting base 2 and abut against the adjustment block 52 and the round pad 53 respectively. The several spring assemblies 55 pass through the lens mounting base 2 and are connected to the reflector mount 1.

[0026] Specifically, the lens mounting base 2 is mounted on the reflector base 1 via the adjusting assembly 5, and the lens cap 4 mounts the lens 3 onto the through hole 21 of the lens mounting base 2. The lens mounting base 2 uses the steel ball 51 as a reference positioning point. When the lens mounting base 2 tilts around the steel ball 51, the top of one threaded joint 54 moves linearly along the adjusting block 52, and the top of the other threaded joint 54 rotates around the circular pad 53. Three spring assemblies 55 are used to connect the lens mounting base 2 and the reflector base 1.

[0027] When the angle of lens 3 needs to be adjusted, rotate to loosen the two threaded joints 54, and move the lens mounting seat 2 so that it tilts around the steel ball 51, thereby adjusting the pitch angle of the lens mounting seat 2. Once the angle is adjusted to the correct position, tighten the locking nut on the threaded joints 54 to complete the angle adjustment of the lens mounting seat 2, thus completing the lens angle adjustment. During the adjustment, the lens mounting seat 2 remains firmly against the reflector seat 1 under the force of the springs 552 of the three spring assemblies 55.

[0028] In the above structure, the spring assembly 55 stretches the lens mounting base 2 and the reflector base 1, ensuring that they remain firmly secured. The angle adjustment of the lens mounting base 2 around the steel ball 51 is controlled by rotating the threaded joint 54, making operation simple, convenient, and quick. This reflector device not only improves adjustment efficiency but also reduces adjustment difficulty, requiring no prior experience.

[0029] like Figure 1 and Figure 2 As shown, in one embodiment, the bottom of the lens cap 4 of the sealed adjustable reflector device is connected to the lens mounting base 2 via several disc springs 41, and the top of the lens cap 4 extends into the through hole 21 of the lens mounting base 2 and fits against the lens 3. In the prior art, the lens cap 4 directly presses and locks the lens 3. When the lens 3 is used, thermal expansion and contraction cause deformation. Due to the locking of the lens cap 4, it cannot be released, resulting in deformation, damage, and changes in the light spot of the lens 3. This application connects the lens cap 4 and the lens mounting base 2 with three disc springs 41, so that the lens cap 4 has a tension allowance. When the lens 3 expands due to heat and deforms, the lens 3 releases the deformation force on the lens mounting base 2, and the lens mounting base 2 compresses the disc springs 41 for adjustment, thereby protecting the lens 3, improving the service life of the lens 3, and ensuring the accuracy of the device.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the lens cap 4 of the sealed adjustable reflector device is provided with a groove 42 for heat dissipation of the lens 3. This heat dissipation structure improves the heat dissipation effect on the lens 3.

[0031] like Figure 1 As shown, in one embodiment, a first sealing ring is provided between the lens mounting base 2 and the lens cap 4 of the sealed adjustable reflector device, and a second sealing ring is provided between the lens mounting base 2 and the reflector seat 1. The provision of the first and second sealing rings improves the sealing performance of the device, preventing fine particles from entering the device and damaging the lens 3, thus protecting the lens 3.

[0032] like Figure 2 As shown, in one embodiment, the spring assembly 55 of the sealed adjustable reflector device includes a screw 551 and a spring 552. The spring 552 is sleeved on the screw 551 and located inside the lens mounting base 2. The screw 551 passes through the lens mounting base 2 and is threadedly connected to the reflector base 1. The two ends of the spring 552 abut against the ends of the screw 551 and the lens mounting base 2, respectively. After the screw 551 passes through the lens mounting base 2 and is threadedly connected to the reflector base 1, a preload is applied to the spring 552. The opening and closing of the threaded pair 54, in conjunction with the extension and retraction of the spring 552, allows for the adjustment of the angle of the lens mounting base 2. This arrangement facilitates the fastening of the lens mounting base 2 and the reflector base 1, ensuring that the lens mounting base 2 is always tightly against the reflector base 1.

[0033] like Figure 2 As shown, in one embodiment, the adjusting block 52 of the sealed adjustable reflector device is provided with a V-groove 521 for linear movement of the threaded pair 54. This arrangement ensures that the threaded pair 54 moves linearly along the V-groove 521.

[0034] like Figure 2 As shown, in one embodiment, the circular pad 53 of the sealed adjustable reflector device is made of high-strength stainless steel. This design ensures that the circular pad 53 will not dent due to pressure from the threaded joint 54 during long-term use, thus ensuring adjustment accuracy.

[0035] like Figure 2 As shown, in one embodiment, the lens mounting base 2 of the sealed adjustable reflector device is provided with a boss 22, and the reflector seat 1 is provided with a receiving groove 11 to accommodate the boss 22. This arrangement facilitates the installation of the reflector on the lens mounting base 2.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
