Description

Technical Field

[0001] This utility model belongs to the field of aiming scope technology, and particularly relates to the waterproof structure of a holographic aiming scope. Background Technology

[0002] A holographic sight is a high-tech optical sight that utilizes holographic imaging technology to achieve rapid and precise aiming. Its core technology involves using lasers to record a holographic image of the target and aiming mark on a special holographic film, and then reproducing the three-dimensional front sight in real time during observation. It is not limited by the parallax of traditional mechanical sights; the shooter simply needs to align the reproduced aiming mark with the target to complete the aiming. It features a wide field of view, clear visibility from multiple angles, rapid response, and strong resistance to vibration and interference. It is widely used in military and police tactical operations, shooting sports, and high-end civilian fields, significantly improving aiming efficiency and shooting accuracy in dynamic environments.

[0003] Most existing holographic sights lack a waterproof structure in practical use. In humid environments or when encountering rain, snow, or fog, moisture can easily seep into the sight body, causing moisture damage to internal precision optical components such as the holographic film, laser module, and circuit components. This can lead to fogging, short circuits, or component corrosion, affecting the normal use of the sight, reducing image clarity and aiming accuracy, and in severe cases, even causing equipment damage and significantly shortening its lifespan. Especially in field operations, rainy training, or extreme weather conditions, the lack of waterproof performance becomes a significant weakness in its reliability and practicality. Therefore, we propose a waterproof structure for holographic sights. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof structure for a holographic sight to solve the problems mentioned in the background art.

[0005] In view of this, on the one hand, the present invention provides a waterproof structure for a holographic sight, comprising: The housing is irregularly shaped and has an internal space for accommodating optical components. A control box is located at the rear end of the housing, and a base plate is located at the bottom of the housing. The base plate is fixedly installed at the bottom of the housing by bolts. An optical lens, wherein the optical lens is fitted into a circular mounting position on the top of the housing; A first sealing assembly is disposed between the housing and the control box and is used to seal the connection between the housing and the control box; The second sealing assembly is disposed between the housing and the base plate and is used for sealing the connection between the housing and the base plate.

[0006] The aforementioned waterproof structure achieves reliable waterproofing of the holographic sight in wet and rainy conditions through layered sealing and structural compensation, while ensuring optical performance and operational stability, thus facilitating user operation.

[0007] In the above technical solution, the edges of the optical lens are further rounded and bonded to the circular mounting position on the top of the housing with waterproof optical adhesive.

[0008] In this technical solution, the optical lens is made of glass and is waterproof. The lens is sealed and filled with waterproof optical adhesive around its perimeter, which fixes the position of the lens and prevents water vapor from entering through the gap between the lens and the outer shell.

[0009] In the above technical solution, a light source is further provided inside the control box. The light source protrudes, and a sealing bushing is surrounding the protruding portion. The sealing bushing is made of elastic silicone. The first sealing assembly includes a circular sealing groove and a sealing ring. A circular sealing groove is formed at the contact interface between the outer shell and the protruding portion of the control box. The sealing ring is embedded in the circular sealing groove and abuts against the top of the protruding portion. The sealing ring is made of elastic silicone, and static sealing is achieved by pressing the control box and the outer shell together.

[0010] In this technical solution, the control box and the outer shell are two relatively independent components. The protruding light source increases the contact area between the two components, improving the fault tolerance. The sealing bushing and sealing ring have a certain degree of elasticity. When the control box and the outer shell are pressed together, the sealing bushing and sealing ring are compressed, filling the gap between them. Static sealing is achieved through the pressing of the control box and the outer shell.

[0011] In the above technical solution, the second sealing component further includes a mounting groove and a sealing ring. The mounting groove is formed at the bottom of the housing, and the sealing ring is embedded in the mounting groove. The sealing ring is made of elastic silicone, and the base plate is fixed and squeezed to the sealing ring by bolts.

[0012] In this technical solution, the outer shell is sealed to the base plate through a second sealing component: an annular mounting groove is opened at the bottom of the outer shell, and elastic silicone is embedded inside; when the base plate is fixed by bolts, its bottom surface squeezes the sealing ring, which is squeezed and fills the gap to achieve a waterproof effect.

[0013] In the above technical solution, further, buttons are distributed on the surface of the control box, and the control box contains a control circuit inside. When the button is pressed down, it abuts against the control circuit, and the abutting interface is provided with a waterproof membrane covering the control circuit.

[0014] In this technical solution, a waterproof membrane is set at the contact interface, which not only protects the control circuit from physical damage, but also effectively prevents moisture from seeping in through the button gaps and corroding the control circuit.

[0015] In the above technical solution, furthermore, the button area on the surface of the control box is covered with a rubber sealing cover, and the rubber sealing cover is interference-fitted with the control box housing.

[0016] In this technical solution, the button area on the surface of the control box is covered with a rubber sealing cover that is interference-fitted with the housing of the control box to prevent water from seeping into the interior of the control box through the button gaps.

[0017] On the other hand, this application proposes a holographic sight, including the waterproof structure described in any of the above technical solutions.

[0018] The beneficial effects of this utility model are: 1. The outer shell serves as the main load-bearing structure. At the rear end of the holographic sight, when the control box is pressed against the outer shell, the sealing bushing and sealing ring are compressed, filling the gap between them to form a static seal. At the base, the outer shell is sealed to the base plate through a second sealing component. An annular mounting groove is opened at the bottom of the outer shell. When the base plate is fixed by bolts, its bottom surface squeezes the sealing ring, causing it to compress and fill the gap to prevent liquid water from penetrating.

[0019] 2. The top optical window consists of optical lenses and a surrounding waterproof optical sealant to prevent liquid water intrusion. A waterproof membrane is installed inside the control box's control circuitry to effectively prevent moisture from eroding the circuitry and ensure the holographic sight functions normally. This waterproof structure and the various components of the holographic sight, through layered sealing and structural compensation, achieve reliable waterproofing of the holographic sight in humid and rainy conditions, while simultaneously ensuring optical performance and operational stability, thus facilitating user operation.
