When fixing the lamp, only one screw needs to be adjusted to achieve the adjustment of the lamp lighting direction to any angle within a certain range.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] In the related art, the lamp base and the ball socket base are fixed by the cooperation between the hemispherical nut and the mounting screw, so as to achieve the fixing of the lamp at different angles. However, when the mounting screw and the hemispherical nut are locked, the spherical surface of the hemispherical nut is easy to rotate relative to the inner wall of the ball socket base, which affects the installation efficiency.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0046] At present, the development and widespread application of smart cameras have greatly met the needs of people's lives and work. The main ways to use smart cameras include placement, hanging (such as fixing on the wall or the side of a column), and ceiling (generally the camera is facing down and the bottom of the camera is fixed on the ceiling, which is also called inverted installation). Both hanging and ceiling installation methods require the use of brackets for fixing. Common brackets mainly add a base to fix the smart camera, fix the base on the wall or ceiling, and then fix the smart camera on the base to meet the needs of hanging and ceiling installation. However, this fixing method cannot adjust the pitch angle of the camera. This problem is more obvious in the use of binocular cameras. When using, there is a mismatch between the height of the fixed position and the angle of the required monitoring screen. The fixed lens cannot face the target monitoring area and cannot fully meet the use requirements.

[0047] In terms of the angle adjustment of the smart camera, a ball socket is usually set at one end of the bracket, and the other end of the bracket is connected to the base. The angle of the camera is adjusted by adjusting the ball head to cooperate with the ball socket of the bracket, and then the adjusting ball head is fixed by means of locking blocks and locking bolts to achieve fixation of the camera at different angles. This fixing structure is relatively complicated.

[0048] In the related art, the lamp base and the ball socket base are fixed by the cooperation between the hemispherical nut and the mounting screw, so as to achieve the fixing of the lamp at different angles. However, when the mounting screw and the hemispherical nut are locked, the spherical surface of the hemispherical nut is easy to rotate relative to the inner wall of the ball socket base, which affects the installation efficiency.

[0049] Combination Figure 1-6As shown, the embodiment of the present disclosure provides a fixing and adjusting device for a camera, including a base 10, a bracket 20, a hemispherical fixing member 30 and a fixing matching member 40, wherein the base 10 is provided with a spherical groove 11, and the spherical groove 11 is provided with a first positioning hole 12; the bracket 20 includes a top end 21 and a bottom end 22, and an accommodating cavity 23 is defined between the top end 21 and the bottom end 22, and the outer surface of the top end 21 is spherically convexly arranged, arranged in the spherical groove 11 and capable of rotating relative to the spherical groove 11, the top end 21 is provided with a second positioning hole 211, and the bottom end 22 is suitable for connecting with the camera; the hemispherical fixing member 30 is provided with a In the accommodating cavity 23, there is an abutting surface 341 that can abut against the inner surface of the top end 21; the fixed fitting 40 is suitable for penetrating the first positioning hole 12 and the second positioning hole 211, and is matched and connected with the hemispherical fixing part 30 to fix the top end 21 of the bracket 20 with the base 10; wherein the size of the second positioning hole 211 is larger than the radial size of the fixed fitting 40, the base 10 is provided with a first limiting portion 13, and the hemispherical fixing part 30 is provided with a first limiting matching portion 33, and the first limiting portion 13 cooperates with the first limiting matching portion 33 to limit the hemispherical fixing part 30 to the base 10.

[0050] The bracket 20 is used to fix the camera and adjust the camera angle. In this application, the spherical groove 11 is set at the front end of the base 10 as an example. The spherical groove 11 and the top 21 of the bracket 20 are installed in coordination, and the pitch angle of the camera can be adjusted and the camera can be fixed at the front end of the base 10.

[0051] The outer surface of the top 21 of the bracket 20 is spherically protruded, and the upper surface of the hemispherical fixing piece 30 is spherically protruded to form an abutment surface 341. When fixed and locked, the hemispherical fixing piece 30 can improve the fit with the top 21 of the bracket 20 in the accommodating cavity 23, and better squeeze the top 21 of the bracket 20 to complete the fixation.

[0052] By adopting the fixing and adjusting device for the camera provided by the embodiment of the present disclosure, the hemispherical fixing member 30 is limited to the base 10 through the cooperation of the first limiting portion 13 and the first limiting matching portion 33, so that when the fixing matching member 40 is matched and connected with the hemispherical fixing member 30, the hemispherical fixing member 30 can be prevented from rotating relative to the bracket 20, thereby improving the installation efficiency. The outer surface of the top 21 of the bracket 20 is spherically convex, arranged in the spherical groove 11 of the base 10, and can rotate relative to the spherical groove 11, thereby driving the camera connected to the bottom 22 of the bracket 20 to adjust the angle. The hemispherical fixing member 30 located in the accommodating cavity 23 of the bracket 20 is against the inner surface of the top 21, and the top 21 is pressed toward the base 10 during the fixing process. The fixing matching member 40 is sequentially penetrated with the first positioning hole 12 of the spherical groove 11 and the second positioning hole 211 of the top 21, and cooperates with the hemispherical fixing member 30 to fix the top 21 of the bracket 20 with the base 10. The bracket 20 is fixed to the base 10 only through the cooperation between the hemispherical fixing member 30 and the fixed fitting member 40, so that the camera can be fixed at any angle. At the same time, the size of the second positioning hole 211 is larger than the radial size of the fixed fitting member 40, so that the bracket 20 can rotate relative to the fixed fitting member 40. After the fixed fitting member 40 is penetrated with the first positioning hole 12 and the second positioning hole 211, the bracket 20 and the base 10 are initially limited, and the bracket 20 can still rotate relative to the fixed fitting member 40 and the base 10. Combined with the spherical matching surface between the spherical top 21 of the bracket 20 and the spherical groove 11 of the base 10, the camera can be adjusted at any angle. After the bracket 20 is adjusted to a suitable angle, the hemispherical fixing member 30 and the fixed fitting member 40 are fixedly connected, which expands the adjustable range of the camera fixed angle.

[0053] It is understandable that the relative position of the bracket 20 and the base 10 can also be adjusted first, and then the fixing fitting 40 is penetrated through the first positioning hole 12 and the second positioning hole 211, and the hemispherical fixing member 30 is fixedly connected with the fixing fitting 40 to achieve the angle adjustment and fixation of the bracket 20. The present application does not limit the installation order between the base 10, the bracket 20, the hemispherical fixing member 30 and the fixing fitting 40.

[0054] Optionally, combined Figure 2-3 and Figure 6 As shown, the first limiting portion 13 is a convex rib 131 , the first limiting matching portion 33 is a slot 331 , and the convex rib 131 can pass through the second positioning hole 211 and extend into the slot 331 to limit the hemispherical fixing member 30 .

[0055] The rib 131 provided on the base 10 passes through the second positioning hole 211 and extends into the slot 331 of the hemispherical fixing member 30. The rib 131 cooperates with the slot 331 to limit the hemispherical fixing member 30 to the base 10. The limiting structure of the rib 131 and the slot 331 is simple and easy to operate.

[0056] It can be understood that one of the first limiting portion 13 and the first limiting matching portion 33 can also be a buckle, and the other can be a hook, and the hook and the buckle are engaged with each other to limit the hemispherical fixing member 30 to the base 10.

[0057] Optionally, combined Figure 2 and Figure 6 As shown, the outer surface of the rib 131 is composed of multiple bends to form a convex polygon; the inner surface of the slot 331 is composed of multiple bends to form a concave polygon, and the number and shape of the bends of the convex polygon and the concave polygon are consistent, so that the convex polygon can be embedded in the concave polygon for locking.

[0058] The outer surface of the rib 131 is set as a convex polygonal structure, and the inner surface of the slot 331 is set as a concave polygonal structure. When the hemispherical fixing part 30 is a hemispherical fixing nut 32 and the fixing fitting 40 is a fixing screw 41, when the fixing screw 41 and the hemispherical fixing nut 32 are locked, the hemispherical fixing nut 32 will not rotate synchronously with the rotation of the fixing screw 41, thereby improving the assembly efficiency.

[0059] This application takes the convex rib 131 as a convex hexagonal structure and the slot 331 as a concave hexagonal structure as an example. The hexagonal structure can balance and disperse the forces to the maximum extent, reduce the distortion and deformation of the structure, and has good stability.

[0060] Optionally, combined Figure 2-3 and Figure 6 As shown, the hemispherical fixing member 30 is provided with a fixing hole 31 arranged opposite to the first positioning hole 12, the fixing matching member 40 is matched and connected with the fixing hole 31, the convex rib 131 is arranged in the spherical groove 11 of the base 10 and is circumferentially arranged along the first positioning hole 12; the card groove 331 is arranged on the upper surface of the hemispherical fixing member 30 and is circumferentially arranged along the fixing hole 31.

[0061] After the fixing fitting 40 is penetrated with the first positioning hole 12 and the second positioning hole 211, it can cooperate with the fixing hole 31 to achieve fixed connection. A convex rib 131 is provided in the spherical groove 11 of the base 10 along the circumference of the first positioning hole 12, and a clamping groove 331 is provided on the upper surface of the hemispherical fixing member 30 along the circumference of the fixing hole 31. The convex rib 131 provided in the spherical groove 11 of the base 10 passes through the second positioning hole 211 and extends into the clamping groove 331 of the hemispherical fixing member 30. The convex rib 131 cooperates with the clamping groove 331 to limit the hemispherical fixing member 30 to the base 10, and align the fixing hole 31 with the first positioning hole 12 and the second positioning hole 211, so that the fixing fitting 40 is convenient to penetrate the first positioning hole 12, the convex rib 131, the second positioning hole 211, the clamping groove 331 and the fixing hole 31, and is assembled with the hemispherical fixing member 30, thereby improving assembly efficiency.

[0062] Optionally, combined Figure 2-3 As shown, the hemispherical fixing member 30 is a hemispherical fixing nut 32, and the fixing hole 31 is a threaded hole 321; the fixing fitting 40 is a fixing screw 41, which passes through the first positioning hole 12 and the second positioning hole 211, and is inserted into the threaded hole 321 to be threadedly fastened with the fixing nut.

[0063] The hemispherical fixing member 30 and the fixing fitting member 40 are detachably fastened by threaded connection, and have a simple structure and are easy to operate.

[0064] The hemispherical fixing nut 32 can be a plastic part, and a copper nut is embedded in the fixing hole 31. The copper nut cooperates with the fixing screw 41 to complete the locking between the bracket 20 and the base 10. When the fixing screw 41 is locked with the hemispherical fixing nut 32, the bracket 20 is squeezed tightly on the base 10, and the fastening between the bracket 20 and the base 10 is achieved by friction.

[0065] It is understandable that the fixing fitting 40 may also be a fixing bolt. The hemispherical fixing member 30 and the fixing fitting 40 may also be fasteners of other detachable connection matching modes, such as a pin hole and a pin.

[0066] Optionally, the second positioning hole 211 extends in the front-to-back direction so that the bracket 20 can rotate in the front-to-back direction relative to the fixed fitting 40 in the spherical groove 11; and / or, the second positioning hole 211 extends in the left-right direction so that the bracket 20 can rotate in the left-right direction relative to the fixed fitting 40 in the spherical groove 11.

[0067] The second positioning hole 211 extends in the front-to-back direction, so that the bracket 20 can rotate in the spherical groove 11 in the front-to-back direction relative to the fixed fitting 40, so that the pitch angle of the camera can be adjusted through the bracket 20. The second positioning hole 211 extends in the left-right direction, so that the bracket 20 can rotate in the left-right direction relative to the fixed fitting 40 in the spherical groove 11, so that the horizontal angle of the camera can be adjusted through the bracket 20. The pitch angle and horizontal angle of the camera are adjustable to meet the requirements of a specific monitoring angle.

[0068] Optionally, combined Figure 3-5 As shown, when the second positioning hole 211 extends in the front-to-back direction so that the bracket 20 can rotate in the spherical groove 11 relative to the fixing fitting 40 in the front-to-back direction, there is a gap between the second positioning hole 211 and the fixing fitting 40 in the left-right direction.

[0069] In the case where the bracket 20 is not completely fixed vertically, the left and right inclination angles of the bracket 20 can be adjusted within the gap range to ensure that the camera is installed vertically. Figure 3-5 As shown, in the disclosed embodiment, the second positioning hole 211 extends along the front-to-back direction, and there is a gap between the second positioning hole 211 and the fixed fitting 40 in the left-to-right direction. The extension dimension of the second positioning hole 211 along the front-to-back direction can achieve a pitch angle of ±30° of the bracket 20, and the gap in the left-to-right direction can achieve a left-right horizontal fine-tuning angle of ±7° of the bracket 20.

[0070] It is understandable that when the second positioning hole 211 extends in the left-right direction so that the bracket 20 can rotate in the spherical groove 11 relative to the fixed fitting 40, a gap may also exist between the second positioning hole 211 and the fixed fitting 40 in the front-back direction.

[0071] Optionally, the spherical groove 11 is further provided with a clearance groove 111 along the circumference, which is used to provide a rotation space for the top 21 of the bracket 20 when the bracket 20 rotates relative to the spherical groove 11. The clearance groove 111 is arranged along the circumference of the spherical groove 11, which can provide a larger activity space for the rotation of the bracket 20. At the same time, the edge of the clearance groove 111 also limits the bracket 20, and combined with the opening size of the second positioning hole 211, the rotation angle of the bracket 20 is limited.

[0072] Optionally, combined Figure 6 As shown, a plurality of ribs 14 are further provided in the spherical groove 11 of the base 10, and the ribs 14 are protruded toward the top 21 of the bracket 20 and can abut against the outer surface of the top 21; and / or, in combination Figure 2As shown, a plurality of grooves 34 are formed on the abutting surface 341 of the hemispherical fixing member 30 , and the abutting surfaces 341 reserved between the notches 342 of the grooves 34 can abut against the inner surface of the top end 21 of the bracket 20 .

[0073] A plurality of ribs 14 are provided on the inner surface of the spherical groove 11 of the base 10. By abutting the ribs 14 against the outer surface of the top 21, the contact area between the inner surface of the spherical groove 11 and the outer surface of the top 21 of the bracket 20 can be reduced, so that the locking force is more concentrated and the friction resistance can be increased, thereby improving the fastening effect.

[0074] Optionally, the plurality of ribs 14 are distributed sequentially along the longitude direction and / or the latitude direction of the spherical groove 11 .

[0075] The plurality of ribs 14 may be distributed in sequence along the longitudinal direction of the spherical groove 11, or may be distributed in sequence along the latitudinal direction of the spherical groove 11, or may be distributed alternately in sequence along the longitudinal direction and the latitudinal direction of the spherical groove 11. The present application takes the case where the plurality of ribs 14 are distributed alternately in sequence along the longitudinal direction and the latitudinal direction of the spherical groove 11 as an example, which can better enhance the locking effect.

[0076] Similarly, a plurality of grooves 34 are provided on the abutting surface 341 of the hemispherical fixing part 30, and the abutting surface 341 reserved between the notches 342 of the plurality of grooves 34 abuts against the inner surface of the top end 21 of the bracket 20, thereby reducing the contact area between the abutting surface 341 of the hemispherical fixing part 30 and the inner surface of the top end 21 of the bracket 20, making the locking force more concentrated and increasing the friction resistance, thereby improving the fastening effect.
