[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figures 1-5 As shown, the present invention provides a waterproof structure in the first aspect, which includes a housing 100 and a first waterproof component 200. The housing 100 is provided with a through hole 1011 communicating with the interior. The first waterproof component 200 is installed at the through hole 1011 to seal the through hole 1011. A wire can pass through the first waterproof component to enter the housing 100. The first waterproof component 200 forms a wire-binding hole 204 at the point where the wire is inserted. When the wire passes through the first waterproof component 200, the inner wall of the through hole 1011 is tightly attached to the outer wall of the wire.

[0029] Specifically, the interior of the housing 100 is used to install electronic components, circuit boards, data transmitters, and other structures. Therefore, it is necessary to introduce wires from the outside for electrical connection. Here, the wires pass through the through hole 1011 into the interior of the housing 100. The first waterproof component 200 is set at the through hole 1011. The first waterproof component 200 is made of puncture-resistant waterproof material. When the wire passes through the through hole 1011, its end will come into contact with the first waterproof component 200 and puncture the first waterproof component 200 to enter the interior of the housing 100. During this process, the first waterproof component 200 forms a wire-binding hole 204 at the point where the wire passes through. The inner wall of this wire-binding hole 204 is in close contact with the outer wall of the wire. That is, the fragment formed by the puncture of the first waterproof component 200 surrounds the outer wall of the wire, effectively preventing water stains from entering the interior of the housing 100 along the wire, while also providing a restraining force to bind the wire, ensuring that the wire does not become tangled when entering the housing 100.

[0030] Furthermore, a plurality of positioning posts 1012 are provided around the first side of the through hole 1011 facing the outside, and a positioning plate 201 is provided on the first waterproof component 200. The positioning plate 201 is provided with a plurality of positioning holes 202. The positioning plate 201 is attached to the first side of the through hole 1011, and the plurality of positioning holes 202 are respectively fitted into the plurality of positioning posts 1012.

[0031] The first waterproof component 200 is provided with a waterproof column 203 that extends into the through hole 1011 and is placed inside the housing 100. The waterproof column 203 is hollow inside.

[0032] Specifically, to facilitate the quick and accurate installation of the first waterproof component 200 into the through hole 1011, a positioning plate 201 with positioning holes 202 is provided on the first waterproof component 200. A plurality of positioning posts 1012 are also correspondingly provided on the first side of the through hole 1011. The first waterproof component 200 is fitted into the plurality of positioning posts 1012 through the positioning holes 202 on the positioning plate 201, thereby achieving quick and accurate installation of the first waterproof component 200. The material structure is designed to be breakable. When the wire passes through the waterproof post 203 and its end is broken, the fragment formed by the broken end will adhere to the wire, thereby achieving a waterproof effect.

[0033] In another embodiment, the first waterproof component 200 extends into the through hole 1011 and is a waterproof column 203 structure. Its end is composed of multiple leaflets. The deflection direction of the multiple leaflets is towards the central axis of the waterproof column 203. The wire passes through the column body of the waterproof column 203 and exits through the multiple leaflets into the housing 100. During this period, the column body of the waterproof column 203 and the multiple leaflets are attached to the wire, which can effectively prevent water stains from entering the housing 100 along the wire.

[0034] Furthermore, the waterproof structure also includes a cover 400 and a second waterproof component 300. The housing 100 has an opening on one side, the cover 400 covers the housing 100 and covers the opening of the housing 100, and the second waterproof component 300 is disposed on the outer wall of the housing 100 and abuts against the inner wall of the cover 400.

[0035] Specifically, the housing 100 and the cover 400 are installed in a semi-enclosed structure, where the outer wall of the housing 100 is completely covered by the cover 400. The second waterproof component 300 is installed on the outer wall of the housing 100, between the outer wall of the housing 100 and the inner wall of the cover 400, to fill the gap between the housing 100 and the cover 400, effectively isolating water stains from the outside and preventing water stains from entering the housing 100 through the gap. Moreover, the cover 400 also adopts a semi-enclosed cover structure, which also prevents water stains from entering the housing 100 from above the cover 400, thus improving the waterproof effect of this structure.

[0036] Furthermore, the waterproof structure also includes a pad 500 and a fastener 600. The pad 500 is attached to the positioning plate 201 and the fastener 600 fixes the pad 500 to the housing 100.

[0037] Specifically, although the positioning pin 1012 and the positioning hole 202 can provide a certain degree of fixation, the strength is still insufficient. In this embodiment, an additional pad 500 and a fastener 600 are added to help fix the positioning plate 201 to the housing 100. The fastener 600 includes, but is not limited to, screw structures, fastener structures, magnetic components, etc.

[0038] Furthermore, at least one annular groove 1013 is provided on the outer wall of the housing 100, and the second waterproof component 300 includes a waterproof ring, which is adapted to the annular groove 1013 and installed in the annular groove 1013. The thickness of the waterproof ring is greater than the depth of the annular groove 1013.

[0039] Furthermore, both the first waterproof component 200 and the second waterproof component 300 are made of elastic waterproof material.

[0040] The interior of the waterproof column 203 features a cavity design that narrows from wide to narrow. The narrower end is the end that is pierced by the wire. Due to this cavity design and the choice of elastic waterproof material, although there is some resistance when the wire enters the waterproof column 203, the wire can still pass through the waterproof column 203. The narrower end will also be in close contact with the outer wall of the wire, which also prevents water stains from entering the housing 100 along the wire, effectively improving the waterproof effect of this structure.

[0041] In a second aspect, this utility model provides a laser detector, including a waterproof structure as described in any of the above solutions.

[0042] 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. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
