[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] like Figures 1-10 As shown, this utility model provides a wireless signal transmission device for a video monitoring module, including a wireless transmission control motherboard 15; the wireless transmission control motherboard 15 is connected to a data interface 10 via a wire; it also includes a housing 1, a guide plate 11, and a threaded rotating rod 14; the wireless transmission control motherboard 15 is bolted to the inner side of the housing 1, the data interface 10 is installed on the lower side of the housing 1, and a rotating shell 5 is rotatably connected to the front side of the housing 1. The outer side of the rotating shell 5 has a through hole, and a transmission antenna 4 is installed in the through hole of the rotating shell 5. The transmission antenna 4 is connected to the wireless transmission control motherboard 15 via a wire. The back plate 3 is bolted to the rear side of the housing 1. A shield 6 is welded to the bottom of the guide plate 11. The housing 1 is slidably connected to the outer side of the guide plate 11. A through hole is provided on the upper side of the housing 1. A rubber sleeve 16 is glued into the through hole of the housing 1. A rotating shaft 12 is inserted into the inner side of the rubber sleeve 16. A direction adjustment knob 2 is welded to the top of the rotating shaft 12. A bevel gear 13 is welded to the bottom of the rotating shaft 12. A clamping knob 9 is welded to the bottom of the threaded rotating rod 14.

[0024] In this embodiment of the present invention, the shield 6 is a rectangular groove structure with an opening on the upper side. The lower side of the groove structure of the shield 6 is provided with three sets of through holes. A sealing cylinder 8 is bonded to the through holes of the shield 6. A rubber gasket 7 is bonded to the edge of the rectangular groove of the shield 6. A through hole is provided at the bottom of the rectangular groove of the shield 6. A threaded rotating rod 14 is rotatably connected to the through hole of the shield 6. During the upward rotation of the threaded rotating rod 14 at the threaded through hole structure on the lower side of the housing 1, the threaded rotating rod 14 drives the rubber gasket 7 bonded to the upper side of the rectangular groove structure of the shield 6 to fit tightly against the lower side of the housing 1. This allows the shield 6 to cover the data interface 10 installed on the lower side of the housing 1. The tight fit between the rubber gasket 7 and the housing 1 prevents dust, moisture and liquid from entering the data interface 10, significantly improving the service life and data transmission reliability of the equipment in complex outdoor environments.

[0025] In this embodiment of the utility model, there are three sets of sealing cylinders 8. Each set of sealing cylinders 8 is made of elastic silicone material. The sealing cylinder 8 is a cylindrical structure that runs through the top and bottom. The bottom of the cylindrical structure of the sealing cylinder 8 is a constricted structure. When the connector of the data transmission line of the video monitoring module passes through the cylindrical structure of the sealing cylinder 8, the constricted structure of the sealing cylinder 8 fits tightly against the outer side of the data transmission line. The elastic constriction of the sealing cylinder 8 provides elastic fit and seal for the data transmission line of any diameter of the video monitoring module through the through hole of the shield 6, preventing external insects and rainwater from seeping into the interior of the shield 6 through the through hole.

[0026] In this embodiment of the utility model, the housing 1 is a rectangular groove structure with an opening on the rear side. The lower side of the housing 1 is provided with a rectangular through groove that runs vertically through the left and right ends. Two sets of guide plates 11 are respectively inserted into the through groove of the housing 1. A protrusion is provided on the lower side of the housing 1 near the rear end.

[0027] In this embodiment of the utility model, the front side of the back plate 3 is provided with long through grooves near the left and right ends, and the rear side of the back plate 3 is densely covered with fin structures. The fin structures increase the contact area with the air in the back plate 3, accelerate the dissipation of heat, and prevent the internal overheating of the housing 1 from causing a decrease in the signal processing performance of the wireless transmission control motherboard 15, thus ensuring the service life of the device and the stability of signal conversion and transmission.

[0028] In this embodiment of the utility model, the rotating shell 5 is a circular cover structure with an opening on the rear side. The outer side of the cover structure of the rotating shell 5 is surrounded by a helical tooth structure near the rear end. The outer tooth structure of the bevel gear 13 is meshed with the helical tooth structure of the rotating shell 5. During the process of the adjustment knob 2 driving the bevel gear 13 to rotate through the rotating shaft 12, the bevel gear 13 drives the rotating shell 5, which is meshed with the outer side, to rotate. The rotating shell 5 drives the transmission antenna 4 installed in the through hole on the outer side to rotate on the front side of the housing 1. Thus, the direction adjustment of the transmission antenna 4 is performed according to the placement and installation space of the housing 1 and the direction of signal transmission, avoiding the dead zone of wireless transmission signal caused by the limitation of the installation space environment of the housing 1.

[0029] Specific usage and function of this utility model embodiment: In this invention, when connecting the data transmission cable connector of the video monitoring module to the signal interface of the wireless signal transmission device, the connector of the data transmission cable is first passed through the elastic silicone sealing sleeve 8. At this time, the constricted structure of the sealing sleeve 8 seals the outer surface of the data transmission cable. Then, the connector is inserted into the data interface 10. Afterwards, the clamping knob 9 is manually rotated, causing the threaded rod 14 to rotate. Since the threaded rod 14 is threadedly engaged in the threaded through-hole of the housing 1, the rotation of the threaded rod 14 causes the shield 6 to move towards… Move upwards until the rubber gasket 7 bonded to the slot of the shield 6 is attached to the lower side of the housing 1. At this time, the shield 6 covers the data interface 10 installed on the lower side of the housing 1, thereby completing the connection between the data transmission line of the video monitoring module and the signal interface of the wireless signal transmission device. If it is necessary to adjust the orientation of the transmission antenna 4, manually rotate the adjustment knob 2. The adjustment knob 2 drives the bevel gear 13 welded to the bottom of the rotating shaft 12 to rotate. The bevel gear 13 drives the rotating shell 5 meshing with the outer side to rotate. The rotating shell 5 drives the transmission antenna 4 to rotate on the housing 1, thereby changing the orientation of the transmission antenna 4.
