Abstract
Description
A waterproof component Technical Field
[0001] This utility model relates to the field of detector accessories, and in particular to a waterproof component. Background Technology
[0002] A laser beam detector is a security device based on laser technology. It consists of a transmitter and a receiver. The transmitter emits a laser beam towards the receiver, creating an invisible laser warning line between them. When an object blocks the laser beam, the laser signal received by the receiver changes, triggering an alarm mechanism.
[0003] To ensure that the laser beam detector can be used normally in outdoor environments, a convex arc-shaped water shield is usually installed at the laser emission point. However, when the laser passes through this water shield, the beam energy will be lost. In rainy weather, water droplets are easy to accumulate on the water shield, causing the beam to refract, which in turn affects the performance of the laser beam detector. Summary of the Invention
[0004] The purpose of this utility model is to address the technical problems existing in the background art by proposing a waterproof component.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

The waterproof component includes a fixing plate, a shielding ring, and a waterproof ring. The fixing plate is installed on the inner wall of the housing, and a lens is provided at the center of the fixing plate. The shielding ring is installed on the fixing plate and surrounds the lens. The first window is embedded at the opening edge of the shielding ring. A protrusion is provided on the outer wall of the shielding ring, and the waterproof ring is fitted on the outer wall of the shielding ring. The two sides of the waterproof ring abut against the protrusion and the inner wall of the housing, respectively.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a link, or a specific connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two groups. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0024] As shown in Figures 1-5, this utility model proposes a waterproof component for installation inside the housing of a laser beam detector. The housing has a first window A, and the waterproof component covers the first window A. The waterproof component includes a fixing plate 100, a shielding ring 200, and a waterproof ring 300. The fixing plate 100 is installed on the inner wall of the housing, and a lens 101 is provided at the center of the fixing plate 100. The shielding ring 200 is installed on the fixing plate 100 and surrounds the lens 101. The opening edge of the shielding ring 200 is embedded in the first window A. A protrusion 201 is provided on the outer wall of the shielding ring 200. The waterproof ring 300 is sleeved on the outer wall of the shielding ring 200, and the two sides of the waterproof ring 300 abut against the protrusion 201 and the inner wall of the housing, respectively.
[0025] Specifically, the cover of the laser beam detector has a cover-like structure. The first window A on it is used to provide a window for the beam emitted by the laser beam detector to pass through. In this embodiment, the waterproof component is built into the inside of the cover and covers the first window A. This is between the emitting end of the beam and the first window A, so that the beam needs to pass through the waterproof component as a medium. Similarly, the waterproof component can isolate the outside world, such as water stains and dust.
[0026] Referring to Figure 1, the fixing plate 100 adopts a central disc with two ear-shaped structures on both sides. The ear-shaped structures on both sides are provided with fixing holes, which are used to fix the fixing plate 100 to the inner wall of the cover using standard fasteners such as screws. After the fixing plate 100 is installed and fixed, the end of the shielding ring 200 on the fixing plate 100 will be directly embedded in the first window A. Since the protrusion 201 is set on the outer wall of the shielding ring 200, when the end of the shielding ring 200 is close to the first window A, the protrusion 201 will also be close to the first window A. At this time, the waterproof ring 300 is squeezed between the protrusion 201 and the inner wall of the cover under the pressure of the protrusion 201, thereby achieving the waterproofing function of the edge of the first window A.
[0027] It should be noted that, as shown in Figure 4, the lens 101 is flush with the emitting end used to emit the beam, so that the beam passes directly through the lens 101 without refraction or other issues that would affect energy loss. Furthermore, with the waterproof component built into the housing and the laser beam detector being placed vertically, the first window A indirectly forms an eaves structure, making it difficult for raindrops to fall directly onto the lens 101, reducing the probability of water stains adhering to the lens 101 and improving the stability of the laser beam detector.
[0028] Furthermore, the lens 101 is formed by an indentation at the center of the fixing plate 100, and the edge of the lens 101 is designed with an arc shape.
[0029] Referring to Figure 4, the lens 101 is in an inward structure relative to the fixed plate 100, which increases the distance between the lens 101 and the first window A, and also increases the travel required for water stains to splash onto the lens 101, thereby further reducing the splashing of external water stains onto the lens 101.
[0030] The curved edge design of lens 101 effectively prevents water from accumulating on the edge of lens 101 due to gravity after splashing onto it, thus affecting the normal use of the laser beam detector. Specifically, the curved design is a rounded design, which allows water stains to flow smoothly out of the lens 101 area.
[0031] Furthermore, the lens 101 has an elongated groove structure, and the shielding ring 200 has a circular ring structure.
[0032] The cover is provided with a panel, and the panel is provided with a second window B. The shape of the second window B is adapted to the shape of the lens 101. The laser beam detector also includes multiple shields 400, which are mounted on the fixing plate 100. The multiple shields 400 are respectively placed between the shielding ring 200 and the lens 101 to enclose the lens 101.
[0033] Furthermore, the second window B has a length dimension greater than the diameter of the shielding ring 200.
[0034] Referring to Figure 5, it can be clearly seen that the sill of the second window B is lower than the edge of the shielding ring 200, so that when water stains flow from the lens 101 to the shielding ring 200, they can flow out of the second window B, thus preventing excessive water stains from accumulating inside the shielding ring 200 and affecting the use of the laser beam detector.
[0035] This utility model proposes a laser beam detector, which includes a waterproof component as described in any of the above-described solutions.
[0036] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions.
