DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, a dual-joint holder 1 according to a first preferred embodiment of the present invention comprises a lower body cover 11, a turning base board 12, a base splint 13, and a base cover 14. The lower body cover 11 comprises a storing trough 111 and a first fixing ear 112 at a lower end thereof. The first fixing ear 112 is inserted into a first reverse U-shaped notches 122 located between a pair of first ears 121 of the turning base board 12. A hooking surface 1221 is provided above the first reverse U-shaped notch 122. Two damping rings 123 are inserted into respective sides of the first ears 121, respectively. A first bolt 124 is inserted through the first reverse U-shaped notch 122 and the first fixing ear 112 and locked by a first nut 125, functioning as a first turning joint 100. By the friction of the first damping rings 123, the first turning joint 100 is able to be positioned and adjusted at a desired angle for a network video camera.
Another end of the turning base board 12 is provided with a second fixing ear 126. The second fixing ear 126 is inserted into a second reverse U-shaped notch 132 between a pair of second fixing ears 131 of the base splint 13. Two damping rings 133 are inserted into respective sides of the second ears 131, respectively. A second bolt 134 is inserted through the second reverse U-shaped notch 132 and the second fixing ear 126 and locked by a second nut 135, functioning as a second turning joint 200. By the friction of the first damping rings 133, the second turning joint 200 is able to positioned and adjusted at a desired angle for a network video camera.
The base splint 13 is fixed to a fixing seat 141 of the base cover 14. An upper body cover 21 of a network video camera 2 is penetrated with a key A for taking a photograph. A camera lens lid 22 is to secure a lens module 23, a light emitting diode 231 and a circuit board 24 to the lower body cover 11. By the fastening and turning of the first and second damping rings 123 and 133, the first turning joint 100 and the second turning joint 200 are adjusted for a desired angle of the lens module 23 of the network video camera 2, providing a changeable adjustment for the lens module 23. The present invention may be mounted on a screen 3 (as shown in FIGS. 3 and 6), or on a flat surface 14 (as shown in FIG. 4). The base cover 14 is able to be stored in the storing trough 111 of the lower body cover 11 via the first turning joint 100 and the second turning joint 200, as shown in FIG. 5. This provides a succinct appearance and a convenient way for adjustment and storage.
As shown in FIGS. 1 through 6, when the present invention is mounted on the screen 3, the turning base board 12 and the base cover 14 will be pulled open through the second turning joint 200, the hooking surface 1221 will engage with the front edge of the screen 3, and the base cover 14 will hold against the back of the screen 3. The first turning joint 100 is used to adjust the upward/downward angle of the network video camera 2.
As shown in FIGS. 1, 3 and 5, the base cover 14 may comprises an accommodating trough 142 to accommodate a balance weight 4 therein. The base splint 13 is adapted to cover the accommodating trough 142 and confine the balance weight 4 within the accommodating trough 142, providing an appropriate weight to the base cover 14 so as to balance the weight of the network video camera 2.
As shown in FIG. 1 through 7, the lens module 23 is provided with the light emitting diode 231 at an appropriate position, and the light emitting diode 231 is exposed outside the lens lid 22 to provide a motion status of the network video camera 2.
As shown in FIG. 7, a second preferred embodiment of the present invention is substantially similar to the aforesaid first preferred embodiment, with the exceptions described hereinafter. The upper body cover 21′ of the network video camera 2′ and the base cover 14′ are made in the shape of a cylinder or other 3D geometry shapes.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
