Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a pull-back camera with rotation adjustment. Background Technology

[0002] Currently, community surveillance cameras are one of the most important pieces of equipment in the field of public safety, playing a vital role in the security management of communities. Existing surveillance equipment is becoming increasingly intelligent, enabling all-weather, all-round monitoring functions.

[0003] Existing angle-fixing structures have poor durability. For example, simple buckles are prone to wear due to repeated adjustments, and the friction of the rotating shaft decreases with use. Under long-term frequent adjustments or the influence of harsh outdoor environments, the angle-fixing ability further deteriorates, and an "automatic offset" phenomenon may occur. For example, the camera angle may slightly shift every month without external force. To ensure monitoring accuracy, personnel need to regularly calibrate the angle, which affects normal use. Utility Model Content

[0004] The purpose of this invention is to provide a pull-back camera with rotation adjustment to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A pull-back camera with rotation adjustment includes a top fixed plate mounted on a wall, a rotating frame mounted on the top fixed plate, and a monitoring housing mounted on the rotating frame. The rotating frame is characterized by a rotating structure between the rotating frame and the top fixed plate. The rotating structure includes side rotating blocks formed at both ends of the top fixed plate and side connecting blocks mounted at both ends of the rotating frame. The rotating frame is located between the two side rotating blocks, and a rotating shaft connects the side connecting blocks and the side rotating blocks. Each side connecting block has a first serrated disc, and each side rotating block has a second serrated disc that rubs against the first serrated disc.

[0006] Furthermore: a wiring harness module is connected to the rear of the monitoring housing. The wiring harness module includes a wiring harness mounting plate installed at the rear of the monitoring housing and a wiring harness shell connected to the wiring harness mounting plate. The rear end of the wiring harness shell is formed with a wiring harness hole through which the power supply line passes.

[0007] Furthermore: the harness housing is L-shaped and can rotate around the harness mounting plate.

[0008] Furthermore: the wire harness mounting plate is formed with an annular groove, the cross-section of which is T-shaped, and the wire harness shell is formed with a rotating connecting ring that rotatably engages with the annular groove, the cross-section of which is T-shaped.

[0009] Furthermore: the rotating frame is formed with a ring-shaped plate that surrounds the wire harness shell, and the ring-shaped plate is formed with a connecting surface that fits against the back of the monitoring shell, and the connecting surface is fixedly connected to the back of the monitoring shell.

[0010] Furthermore: the side connection blocks are located on both sides of the monitoring housing.

[0011] Furthermore: the top mounting plate is formed with a top slot for monitoring the movement of the housing, and a buffer surround strip made of silicone material is installed at the bottom of the top slot.

[0012] The beneficial effects of this utility model are as follows: The rotating frame can rotate relative to the top fixed plate through the rotating shaft connection between the side connecting block and the side rotating block, thereby driving the monitoring housing mounted on the rotating frame to rotate and achieving flexible adjustment of the camera angle. The first serrated disk formed on the side connecting block and the second serrated disk formed on the side rotating block make frictional contact. This serrated disk structure can provide a certain resistance through the meshing and friction between the serrations after the camera is adjusted to a suitable angle, preventing the camera from rotating arbitrarily due to external forces or its own weight during use, thus ensuring the stability of the camera angle. The camera may be subjected to external forces such as wind; the serrated disk structure can effectively prevent the camera angle from shifting, ensuring the stability and accuracy of the monitoring image.

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings.

[0018] like Figure 1-3 As shown, a pull-back camera with rotation adjustment includes a top fixed plate 1 mounted on a wall. The top fixed plate 1 is equipped with a rotating frame 11, and the rotating frame 11 is equipped with a monitoring housing 12. A rotating structure is provided between the rotating frame 11 and the top fixed plate 1. The rotating structure includes side rotating blocks 13 formed at both ends of the top fixed plate 1 and side connecting blocks 14 installed at both ends of the rotating frame 11. The rotating frame 11 is located between the two side rotating blocks 13. A rotating shaft 15 connects the side connecting blocks 14 and the side rotating blocks 13. The side connecting blocks 14 are formed with a first serrated disk 16, and the side rotating blocks 13 are formed with a second serrated disk 17 that rubs against the first serrated disk 16.

[0019] The rotating frame 11 is connected to the side connecting block 14 and the side rotating block 13 by a rotating shaft 15, allowing the rotating frame 11 to rotate relative to the top fixed plate 1. This, in turn, drives the monitoring housing 12 mounted on the rotating frame 11 to rotate, enabling flexible adjustment of the camera angle. The first serrated disk 16 formed on the side connecting block 14 and the second serrated disk 17 formed on the side rotating block 13 are in frictional contact. This serrated disk structure provides a certain resistance through the meshing and friction between the serrations after the camera is adjusted to a suitable angle, preventing the camera from rotating arbitrarily due to external forces or its own weight during use, thus ensuring the stability of the camera angle. The camera may be subjected to external forces such as wind, and the serrated disk structure can effectively prevent the camera angle from shifting, ensuring the stability and accuracy of the monitoring image.

[0020] Furthermore, a wiring harness module 2 is connected to the rear of the monitoring housing 12. The wiring harness module includes a wiring harness mounting plate 21 installed at the rear of the monitoring housing 12 and a wiring harness shell 22 connected to the mounting plate 21. The rear end of the wiring harness shell 22 has a wiring harness hole 23 for the power supply line to pass through. The mounting plate 21 rigidly fixes the wiring harness module 2 to the rear of the monitoring housing 12, forming a stable connection point between the wiring harness and the main body of the equipment. The connection between the wiring harness and the monitoring housing 12 is fully enclosed and protected by the wiring harness shell 22, reducing exposed wiring harnesses. The closed structure of the wiring harness shell 22 and the mounting plate 21 forms a semi-sealed space, which can prevent rainwater and dust from directly intruding into the wiring harness connector area.

[0021] Furthermore, the wire harness housing 22 is made of deformable soft plastic material and is L-shaped. The wire harness housing 22 can rotate around the wire harness mounting plate 21. The L-shaped wire harness housing 22 itself has a bending structure, which can realize the transition of the cable in the horizontal and vertical directions. Its rotation function around the wire harness mounting plate 21 can also rotate to the vertical downward or horizontal side-out direction in the ceiling hanging scenario, which can adapt to the needs of internal wiring in the ceiling or wiring along the edge of the ceiling.

[0022] Specifically, the wire harness mounting plate 21 is formed with an annular groove 24, the cross-section of which is T-shaped. The wire harness shell 22 is formed with a rotating connecting ring 25 that rotatably engages with the annular groove 24, the cross-section of which is T-shaped. The wire harness shell 22 achieves rotatable adjustment of its angle through the rotatable engagement of the T-shaped rotating connecting ring 25 with the annular groove 24 of the wire harness mounting plate 21.

[0023] Furthermore, the rotating frame 11 is formed with a ring-shaped plate 26 that surrounds the wire harness shell 22. The ring-shaped plate 26 is formed with a connecting surface 27 that fits against the back of the monitoring shell 12. The connecting surface 27 is fixedly connected to the back of the monitoring shell 12. The back of the monitoring shell 12 fits against the connecting surface 27 of the ring-shaped plate 26 and is aligned with the corresponding holes. Screws are installed in the holes to achieve locking. When the top fixing plate 1 rotates between the rotating frame 11 and the monitoring shell 12, the rotating frame 11 and the monitoring shell 12 rotate synchronously to achieve angle adjustment.

[0024] Side connecting blocks 14 are located on both sides of the monitoring housing 12. These blocks provide primary support and guidance for rotation, while the buffer surround strip 19 at the bottom of the top slot 18 provides auxiliary restraint for the monitoring housing 12 from below. The top fixing plate 1 has a top slot 18 for the monitoring housing 12 to move, and a buffer surround strip 19 made of silicone is installed at the bottom of the top slot 18. The top slot 18 of the top fixing plate 1 provides a dedicated area for the monitoring housing 12 to adjust its angle with the rotating frame 11. The silicone material has excellent elasticity, and the buffer surround strip 19 installed at the bottom of the top slot 18 can absorb impact energy when the monitoring housing 12 rotates to its limit or is subjected to external impact. The silicone buffer surround strip 19 fits tightly against the bottom of the monitoring housing 12, filling the gap between the top slot 18 and the monitoring housing 12.

[0025] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0026] The above description is only a preferred embodiment of this utility model.
