Description

Technical Field

[0001] This application relates to the technical field of lamps, and particularly to a waterproof lamp. Background Art

[0002] Currently, most waterproof lamps on the market place a sealing ring at the bottom of the lens and achieve waterproofing through a forward extrusion method.

As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0043] See Figures 1 - 6 , which shows a waterproof lamp according to a preferred embodiment of the present utility model, including:

[0044] A lamp body 1, the lamp body 1 is provided with a light source 2 and a mounting part 11, and the mounting part 11 is arranged around the light source 2;

[0045] A lens 3, the lens 3 is arranged on the lamp body 1 and covers the light source 2, the bottom of the lens 3 has a sealing groove 31, the sealing groove 31 is arranged around the light source 2, and the sealing groove 31 covers the mounting part 11; and

[0046] The seal 4 is sleeved on the mounting portion 11. The side wall of the seal 4 is provided with a sealing portion 41. The sealing portion 41 is arranged around the light source 2. The sealing portion 41 is in interference fit with the side wall of the sealing groove 31 to seal the gap between the lamp body 1 and the lens 3, prevent external water and liquid from leaking into the interior of the lamp body 1 through the gap between the lamp body 1 and the lens 3, play a good waterproof role, and ensure that the waterproof lamp can always operate normally.

[0047] For the waterproof lamp of the present utility model, by providing a mounting portion 11 arranged around the light source 2 on the lamp body 1, the bottom of the lens 3 having a sealing groove 31 arranged around the light source 2 and covering the mounting portion 11, the seal 4 being sleeved on the mounting portion 11, the side wall of the seal 4 being provided with a sealing portion 41, the sealing portion 41 being arranged around the light source 2, and the sealing portion 41 being in interference fit with the side wall of the sealing groove 31, it is possible to seal the gap between the mounting portion 11 and the lens 3, that is, to seal the gap between the lamp body 1 and the lens 3. Among them, since the sealing groove 31 is located on the lens 3, compared with the structure of using the side wall of the lamp body 1 and the sealing ring for waterproofing in the prior art, the size of the sealing groove 31 is smaller, the dimensional accuracy of the sealing groove 31 can be better controlled, the side wall of the sealing groove 31 has a higher roundness, ensuring that the side wall of the sealing groove 31 is closely attached to the sealing portion 41, improving the waterproof reliability. In addition, the sealing portion 41 on the side wall of the seal 4 is in interference fit with the side wall of the sealing groove 31 to form a side extrusion waterproof structure, so that the lens 3 has no deformation in the vertical direction, avoiding the deformation problem caused by the positive extrusion of the lens 3, and thus being able to avoid affecting the optical performance of the lens 3.

[0048] See Figure 3 , in an embodiment, the outer side wall and the inner side wall of the seal 4 are both provided with a sealing portion 41. The sealing portion 41 on the outer side wall of the seal 4 is in interference fit with the outer side wall of the sealing groove 31, and the sealing portion 41 on the inner side wall of the seal 4 is in interference fit with the inner side wall of the sealing groove 31 to increase the sealing reliability between the lamp body 1 and the lens 3 and double the waterproof performance.

[0049] See Figure 3 , in an embodiment, the seal 4 at least covers the upper part of the mounting portion 11, and the top of the seal 4 abuts against the top wall of the sealing groove 31 to further increase the sealing reliability between the lamp body 1 and the lens 3 and have higher waterproof stability.

[0050] In an embodiment, the seal 4 is a sealing ring made of rubber material, so that the seal 4 has excellent sealing performance, thereby further improving the waterproof reliability.

[0051] In one embodiment, the lens 3 is rotatably connected to the lamp body 1 so that the lens 3 can rotate vertically up and down relative to the lamp body 1, thereby adjusting the distance between the lens 3 and the light source 2, making the light output direction of the waterproof lamp adjustable and meeting the light distribution requirements at different angles.

[0052] See Figure 3 , in one embodiment, the sealing portion 41 extends obliquely downward toward the lens 3, forming an angle between the sealing portion 41 and the side wall of the sealing groove 31, which can reduce the extrusion force between the seal 4 and the lens 3, thereby reducing the friction force. Therefore, when rotating the lens 3, easy operation can be achieved, and a better waterproof effect can be obtained, avoiding the problems that the conventional adjustable-angle lamps on the market are difficult to rotate and cannot be reliably waterproof. The structure is simple and practical, with high reliability and low cost.

[0053] See Figures 2 - 4 and Figure 6 , in one embodiment, the outer peripheral wall of the lens 3 has a guiding groove 32, and the guiding groove 32 extends obliquely upward around the rotation center line of the lens 3, that is, the guiding groove 32 is a slotted structure;

[0054] The lamp body 1 is provided with a guiding member 5, and a part of the guiding member 5 is slidably engaged with the guiding groove 32. Thus, when rotating the lens 3, a part of the guiding member 5 will slide relative to the guiding groove 32, so that the lens 3 moves up and down to change the distance between the lens 3 and the light source 2, thereby realizing the change of the light distribution angle, and being able to play a guiding role in the rotation of the lens 3, making the rotation of the lens 3 smoother and more stable.

In this way, the lens 3 can be locked at a required set angle by the cooperation of the positioning bead 52 and any one of the positioning grooves 33, that is, the lens 3 can be stably maintained at the required set angle. At the same time, by rotating the lens 3, the driving force of the elastic member 53 can be overcome, so that the positioning bead 52 can switch between the locking state and the retracted state, with simple and convenient operation and high efficiency.

[0061] In one embodiment, a plurality of angle marks 34 are provided on the top of the lens 3. The values of the plurality of angle marks 34 are different.

[0063] See Figure 3 , in one embodiment, the housing 51 has an inner cavity, and the elastic member 53 is located in the inner cavity to position and guide the elastic member 53, making the telescopic movement of the elastic member 53 smoother and more stable, so that the telescopic movement of the positioning bead 52 is smoother and more stable, facilitating the flexible switching of the positioning bead 52 between the locking state and the retracted state.

[0064] In one embodiment, the elastic member 53 can be a spring to provide a better driving force for the positioning bead 52, ensuring that the positioning bead 52 can be persistently maintained in the state of cooperating with the positioning groove 33 to improve the locking reliability of the lens 3.

[0065] In other embodiments, the elastic member 53 can also be any one of a leaf spring, a corrugated pipe, a structure made of rubber material, etc.
