[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Please refer to Figures 1 to 3, the present invention provides a waterproof structure for a surveillance camera, comprising: a housing 1, a panel 2 disposed at one end of the housing 1, a waterproof component 3 disposed on the panel 2, and a lens component 4 connected to the waterproof component 3. A waterproof seal groove 21 is provided on the contact surface between the panel 2 and the housing 1, and a first waterproof sealing ring 51 is disposed in the waterproof seal groove 21. The waterproof component 3 includes: a ball head bracket 31, a lens 32 disposed at the front end of the ball head bracket 31, a second waterproof sealing ring 52 sleeved on the ball head bracket 31, a first waterproof pressing plate 33 disposed on the second waterproof sealing ring 52, and a second waterproof pressing plate 34 disposed on the second waterproof sealing ring 52. One end of the second waterproof sealing ring 52 is sleeved on the ball head bracket 31, and the other end of the second waterproof sealing ring 52 is attached to the panel 2. The first waterproof pressing plate 33 is locked on the panel 2 to press the second waterproof sealing ring 52 against the panel 2, and the second waterproof pressing plate 34 is locked on the ball head bracket 31 to press the second waterproof sealing ring 52 against the ball head bracket 31. A spherical surface 311 is provided on the ball head bracket 31, a through hole 22 is provided in the middle of the panel 2, the front end of the ball head bracket 31 passes through the through hole 22 of the panel 2, and the spherical surface 311 contacts the hole wall of the through hole 22. By providing the spherical surface 311 on the ball head bracket 31 and making the spherical surface 311 contact the hole wall of the through hole 22 on the panel 2, it is convenient for the ball head bracket 31 to drive the lens component 4 to move, so that the lens component 4 can obtain more shooting angles and meet the customer's requirements for shooting angle adjustment. When the panel 2 is installed on the housing 1, the first waterproof sealing ring 51 disposed in the waterproof seal groove 21 is deformed by extrusion, so as to fill the waterproof seal groove 21 and prevent external rainwater from entering the interior of the housing 1 through the joint between the housing 1 and the panel 2, thereby playing a role in protecting the lens component 4 and other components inside the housing 1. By pressing the second waterproof sealing ring 52 against the panel 2 with the first waterproof pressing plate 33, the second waterproof sealing ring 52 is deformed by extrusion to fill the gap between the second waterproof sealing ring 52 and the panel 2, preventing water from passing through and playing a role in waterproof sealing. Similarly, by pressing the second waterproof sealing ring 52 against the ball head bracket 31 with the second waterproof pressing plate 34, the second waterproof sealing ring 52 is deformed by extrusion to fill the gap between the second waterproof sealing ring 52 and the ball head bracket 31, preventing water from passing through and playing a role in waterproof sealing.

[0018] The second waterproof sealing ring 52 includes, from left to right: a U-shaped groove 521, a buffer belt 522, and a fixing plate 523. An installation plate 312 is provided at the rear end of the ball head bracket 31, and the installation plate 312 is embedded in the U-shaped groove 521 to facilitate the connection between the ball head bracket 31 and the second waterproof sealing ring 52. The fixing plate 523 is attached to the panel 2 to facilitate the connection between the panel 2 and the second waterproof sealing ring 52. When the ball head bracket 31 moves on the panel 2 to adjust the viewing angle, one side of the buffer belt 522 of the second waterproof sealing ring 52 is squeezed, and the other side of the buffer belt 522 is stretched, so as to ensure that the waterproof performance will not be affected by the movement of the ball head bracket 31 and ensure the tightness of the monitoring camera.

[0019] A first water stop protrusion 23 is provided on the panel 2 at the position corresponding to the first waterproof pressing plate 33. When the first waterproof pressing plate 33 presses the second waterproof sealing ring 52 onto the panel 2, the first water stop protrusion 23 is embedded in the second waterproof sealing ring 52, thereby improving the waterproof effect.

[0020] A second water stop protrusion 313 is provided on the ball head bracket 31 at the position corresponding to the second waterproof pressing plate 34. When the second waterproof pressing plate 34 presses the second waterproof sealing ring 52 onto the ball head bracket 31, the second water stop protrusion 313 is embedded in the second waterproof sealing ring 52, thereby improving the waterproof effect.

[0021] A lens groove is provided at the front end of the ball head bracket 31, the lens 32 is embedded in the lens groove, and 3M glue is provided between the lens 32 and the ball head bracket 31 to prevent water from entering through the gap between the lens 32 and the ball head bracket 31, thereby improving the waterproof effect.

[0022] Please refer to Figure 4 , a guiding threaded hole 314 is provided on the ball head bracket 31, a slot hole 24 is provided on the panel 2 corresponding to the guiding threaded hole 314, a guiding screw 6 is provided in the guiding threaded hole 314, and the guiding screw 6 passes through the slot hole 24 and is locked in the guiding threaded hole 314. By loosening the guiding screw 6, the ball head bracket 31 can move along the direction of the slot hole 24 to adjust the shooting angle of the lens assembly 4, and then the guiding screw 6 is locked to fix the ball head bracket 31 to obtain the shooting angle required by the user.

[0023] In summary, the present invention presses both ends of the second waterproof sealing ring onto the panel and the ball head bracket respectively through the first waterproof pressing plate and the second waterproof pressing plate, so as to prevent rainwater from entering the inside of the machine shell through the gap between the ball head bracket and the panel, thereby ensuring the waterproof performance of the monitoring camera while satisfying the adjustment of the shooting angle of the lens assembly, and avoiding damage to the monitoring camera due to the infiltration of rainwater.

[0024] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
