Description

Technical Field

[0001] The utility model relates to the field of cameras, in particular to a sealing device for a communication camera. Background Art

[0002] Communication cameras usually refer to network cameras, which are cameras that can remotely transmit images and other data over the Internet. They are now widely used in public safety monitoring, traffic monitoring, environmental monitoring and other aspects.

[0003] Generally, there is a gap between the surveillance camera and the outer shell. When using a communication camera outdoors, environmental factors such as weather changes need to be considered. When it rains, if the seal between the lens and the outer shell is not tight, rainwater will penetrate into the interior and cause damage to internal components, thereby damaging the transmission signal. Utility Model Content

[0004] The utility model aims to provide a sealing device for a communication camera, which effectively solves the problem that the sealing between the communication camera and the housing is not tight, causing rainwater to enter and damaging the transmission signal.

[0005] The technical solution of the utility model is as follows:

[0006] A sealing device for a communication camera comprises a camera body, a protective cover and a mounting frame, wherein the protective cover is above the camera body, the camera body is mounted through the mounting frame, the front end face of the camera body is provided with a camera lens having a convex cross-section, a small diameter section cylinder is outside the camera body and a sealing ring is provided on the ring wall, the front end face of the camera body is provided with an annular groove, the front end face of the camera body is provided with inward circular grooves near the four corners, and a clamping ring is provided at the notch of the circular groove;

[0007] It also includes a lens sealing plate, the side plate of the lens sealing plate is embedded in the annular groove to cover the camera lens, the inner wall of the lens sealing plate is provided with the same sealing ring, the outer wall of the lens sealing plate is provided with a connecting plate, the rear end face of the connecting plate is provided with a fixing pin corresponding to the position of the circular groove, the pin rod of the fixing pin is provided with an elastic fastening ring, and a limiting gap is provided between the elastic fastening ring and the connecting plate. During sealing, when the lens sealing plate is embedded in the annular groove, the clamping ring is stuck in the limiting gap.

[0008] Furthermore, the top of the camera body is symmetrically provided with matching grooves, and the cross-sectional shape of the matching grooves is L-shaped.

[0009] Furthermore, the rear end face of the camera body is provided with a sealed harness sleeve for allowing the camera wires to pass through, and the rear end face of the camera body is symmetrically provided with ventilation grilles, so that the heat generated inside the camera body can be dissipated through the ventilation grilles when encountering high temperatures in summer.

[0010] Furthermore, the shape of the protective cover is L-shaped, and the L-shaped vertical section of the protective cover is at the rear of the camera body to prevent rainwater from entering the interior from the rear end of the camera body, and the length of the horizontal section is greater than the length of the camera body.

[0011] Furthermore, the bottom wall of the protective cover is symmetrically provided with card strips, which are movably stuck in the matching grooves so that the protective cover can move back and forth. When it rains, the vertical section of the protective cover fits against the rear end of the camera device. In summer, the high temperature can be kept at a distance so that the camera body can dissipate heat.

[0012] Furthermore, the number of the circular grooves is not less than two, and the length of the fixing pin is less than the depth of the circular groove, so that after the fixing pin is fully inserted into the circular groove, the elastic fastening ring is clamped into the limiting gap.

[0013] Furthermore, the elastic fastening ring is in the shape of a cone, and the spacing of the limiting gap matches the thickness of the clamping ring, so that the lens sealing plate can completely fix and cover the camera lens.

[0014] The advantages of the utility model are:

[0015] 1. The utility model covers the outer periphery of the camera lens with a lens sealing plate, and a sealing ring is fitted between the two. The elastic fastening ring on the fixing pin is clamped into the limiting gap, thereby achieving the covering of the lens sealing plate, effectively preventing the gap between the camera lens and the camera body shell from being poorly sealed and causing rainwater to penetrate into the interior, thereby improving the sealing performance of the communication camera device.

[0016] 2. The utility model provides a matching groove on the camera body, and the card strip at the bottom end of the protective cover can be moved in the matching groove. The vertical section of the L-shaped protective cover is behind the camera body. When it rains, the protective cover can be pushed forward to make the rear end of the protective cover fit with the rear of the camera body to prevent rainwater from entering from the rear. When encountering high temperatures in summer, the protective cover can be slid backward. The resulting gap can allow the heat emitted by the camera body to be dissipated through the air-permeable grille to avoid damage to internal components caused by excessive temperature.

[0017] 3. The utility model provides a sealed wire harness sleeve at the rear end of the camera body, allowing the camera wires to pass through the sealed wire harness sleeve, thereby preventing rainwater from penetrating into the interior through the gap between the wire harness and the shell, and further improving the sealing performance of the camera device.

When sealing, when the lens sealing plate 9 is embedded in the annular groove 6, the retaining ring 8 is stuck in the limiting gap 13.

[0027] A matching groove 14 is symmetrically provided at the top of the camera body 1 , and the cross-sectional shape of the matching groove 14 is L-shaped.

[0028] The rear end surface of the camera body 1 is provided with a sealed wire harness sleeve 15 for allowing the camera wires to pass through. The rear end surface of the camera body 1 is symmetrically provided with ventilation grilles 16, so that the heat generated inside the camera body 1 can be dissipated through the ventilation grilles 16 when encountering high temperatures in summer.

[0029] The protective cover 2 is L-shaped, and the L-shaped vertical section of the protective cover 2 is at the rear of the camera body 1 to prevent rain from entering the interior from the rear end of the camera body 1 . The length of the horizontal section is greater than the length of the camera body 1 .

[0030] The bottom wall of the protective cover 2 is symmetrically provided with a clamping strip 17, which is movably clamped in the matching groove 14, so that the protective cover 2 can move back and forth. When it rains, the vertical section of the protective cover 2 is attached to the rear end of the camera device.
