Description

Technical Field

[0001] This utility model relates to the field of camera installation technology, and more specifically to a camera installation mechanism. Background Technology

[0002] In fields such as security monitoring, industrial production monitoring, and public area visualization management, cameras need to be fixed to carriers such as ceilings and brackets by installation mechanisms, and must have horizontal and tilt angle adjustment functions to cover the target monitoring area.

[0003] However, existing camera installation mechanisms have the following prominent technical defects in structural design and practical application, making it difficult to meet the needs of efficient installation and adjustment. For example, when adjusting the horizontal angle, tools such as screwdrivers and wrenches are required to remove the positioning screws or clips, and reassembly is required after adjustment. The operation steps are cumbersome (averaging 3-5 steps). Especially in high-altitude installation scenarios, the difficulty of carrying and operating tools is high, which not only increases the time cost of operation, but also increases the safety risks of personnel falling and tools falling.

[0004] To address this technical problem, a mounting mechanism for cameras is provided. Utility Model Content

[0005] The purpose of this invention is to provide a mounting mechanism for a camera to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mounting mechanism for a camera, comprising an L-shaped wall panel with mounting holes, an inverted groove extending through the upper surface of the L-shaped wall panel, and a positioning ring fixedly mounted on the lower surface of the L-shaped wall panel. A T-shaped hollow column is rotatably mounted within the inverted groove, a sleeve is slidably fitted onto the outer surface of the T-shaped hollow column, a hinge frame is fixedly mounted on the lower surface of the sleeve, and an elastic tightening device is provided between the sleeve and the T-shaped hollow column. The upper surface of the hinge frame is in contact with the lower surface of the positioning ring under the action of the elastic tightening device, and an adjustable-angle camera is mounted within the hinge frame.

[0007] Preferably, the inner cavity of the T-shaped hollow column is circumferentially threaded with three internal hexagonal bolts; The inner wall of the sleeve is provided with three vertically arranged mounting slots at equal intervals in the circumference. The elastic tightening device includes three springs, which are fixedly installed in the corresponding mounting slots. Each spring has a U-shaped block fixedly installed at its bottom end. The U-shaped block is slidably installed in the corresponding mounting slot, and the internal hexagonal bolt is snapped into the corresponding U-shaped block.

[0008] Preferably, the lower surface of the positioning ring is provided with 36 positioning grooves at equal intervals in the circumferential direction, and the upper surface of the hinge frame is fixedly installed with 36 protrusions at equal intervals in the circumferential direction, the protrusions being snapped into the corresponding positioning grooves.

[0009] Preferably, a rotating shaft is rotatably mounted through the hinge frame, the top of the camera is sleeved on the outer surface of the rotating shaft, and pin holes are opened through the outer surfaces of both ends of the rotating shaft, with positioning pins being engaged in the pin holes.

[0010] Preferably, multiple damping pads are provided between the top left and right surfaces of the camera and the inner sidewall of the hinge frame, and the damping pads are all sleeved on the outer surface of the rotating shaft.

[0011] Preferably, a stainless steel rain cover is fixedly installed on the outer surface of the hinge frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes an L-shaped wall panel with an inverted groove that is wider at the top and narrower at the bottom, along with a rotatable T-shaped hollow column. This design not only restricts the axial detachment of the T-shaped hollow column but also provides space for its circumferential rotation, thus laying the structural foundation for adjusting the horizontal angle of the camera. An elastic tightening device is constructed by installing springs, U-shaped blocks, and internal hexagonal bolts on the T-shaped hollow column within the sleeve's mounting groove. This provides a uniform upward elastic force to the sleeve, ensuring a tight fit between the hinge frame and the positioning ring, while not hindering the circumferential rotation of the T-shaped hollow column, thus guaranteeing smooth horizontal adjustment. Furthermore, by setting thirty-six circumferentially spaced positioning grooves on the lower surface of the positioning ring and thirty-six corresponding protrusions on the upper surface of the hinge frame, the adjustment accuracy of the camera's horizontal angle reaches 10°. Furthermore, during adjustment, simply pull down the hinge bracket to disengage the protrusion from the positioning groove, rotate it to the target angle, and release it. The spring will automatically engage and lock the mechanism, eliminating the need for screwdrivers, wrenches, or other tools. This simplifies the original 3-5 step operation process, reduces the difficulty of carrying tools during high-altitude operations, and minimizes the safety risks of personnel falling or tools dropping.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-6 This utility model provides a technical solution: A mounting mechanism for a camera includes an L-shaped wall panel 1 with mounting holes for fixing the mechanism to a ceiling, bracket, or other mounting surface using fasteners such as expansion bolts. A recessed groove 11 is formed through the upper surface of the L-shaped wall panel 1, and a positioning ring 12 is fixedly mounted on the lower surface of the L-shaped wall panel 1. A T-shaped hollow column 2 is rotatably mounted within the recessed groove 11. A sleeve 3 is slidably fitted onto the outer surface of the T-shaped hollow column 2, with the outer diameter of the T-shaped hollow column 2 being the same as the inner diameter of the sleeve 3. A hinge frame 4 is fixedly mounted on the lower surface of the sleeve 3, and an elastic tightening device 5 is provided between the sleeve 3 and the T-shaped hollow column 2. The upper surface of the hinge frame 4 is in contact with the lower surface of the positioning ring 12 under the action of the elastic tightening device 5. An adjustable-angle camera 6 is mounted inside the hinge frame 4.

[0022] The inverted groove 11 adopts an inverted convex structure design that is "wider at the top and narrower at the bottom". It can accommodate the head of the T-shaped hollow column 2 and limit its axial fall, while also providing circumferential rotation space for the T-shaped hollow column 2, so that the subsequent camera 6 can achieve horizontal angle adjustment. The positioning ring 12 and the elastic tightening device 5 cooperate to form a positioning structure. The elastic tightening device 5 continuously provides an upward elastic force, which drives the sleeve 3 and the hinge frame 4 to fit upward against the positioning ring 12, ensuring that the hinge frame 4 maintains a stable posture when there is no external force adjustment, and preventing the camera 6 from shifting due to its own weight or slight vibration.

[0023] It should be noted that, in combination Figure 5 and Figure 6As shown, the inner cavity of the T-shaped hollow column 2 is circumferentially and equidistantly threaded with three internal hexagonal bolts 21. The inner side wall of the sleeve 3 is circumferentially and equidistantly provided with three vertically arranged mounting slots 31. The elastic tightening device 5 includes three springs 51, which are fixedly installed in the corresponding mounting slots 31. The bottom end of each spring 51 is fixedly installed with a U-shaped block 52, which is slidably installed in the corresponding mounting slots 31. The internal hexagonal bolts 21 are snapped into the corresponding U-shaped blocks 52.

[0024] The mounting groove 31 of the sleeve 3 provides directional installation space for the spring 51 and the U-shaped block 52, restricting them to sliding only in the vertical direction and preventing the elastic tightening device 5 from being deflected by force. The three springs 51 correspond one-to-one with the internal hexagonal bolt and the U-shaped block 52, and their circumferentially equidistant distribution allows the sleeve 3 to be subjected to a uniform upward elastic force, ensuring that the hinge frame 4 and the positioning ring 12 fit tightly and are subjected to balanced force, preventing the camera 6 from tilting. The slot structure of the U-shaped block 52 is precisely matched with the head of the internal hexagonal bolt 21, achieving a stable engagement between the two. It not only transmits the elastic force of the spring 51, but also slides synchronously with the sleeve 3, while not affecting the circumferential rotation of the T-shaped hollow column 2, ensuring the smooth realization of the horizontal angle adjustment function.

[0025] Combination Figure 4 and Figure 6 As shown, the lower surface of the positioning ring 12 is provided with thirty-six positioning grooves 13 at equal intervals in the circumferential direction, and the upper surface of the hinge frame 4 is provided with thirty-six protrusions 41 at equal intervals in the circumferential direction. The protrusions 41 are snapped into the corresponding positioning grooves 13.

[0026] The thirty-six positioning slots 13 of the positioning ring 12 and the thirty-six protrusions 41 of the hinge frame 4 adopt a one-to-one snap-fit ​​structure. The circumferentially equidistant distribution means that the included angle between adjacent positioning slots 13 and protrusions 41 is 10°, so that the horizontal angle adjustment accuracy of the camera 6 reaches 10° level, which can meet the angle subdivision requirements of most monitoring scenarios.

[0027] The protrusion 41 adopts a rigid structural design, and its shape precisely matches the groove of the positioning groove 13, ensuring no gap after engagement and effectively preventing the camera 6 from shifting horizontally. Under the upward force of the elastic tightening device 5, the protrusion 41 is always tightly engaged in the positioning groove 13, forming a reliable circumferential positioning. When it is necessary to adjust the horizontal angle, simply pull down the hinge bracket 4 to disengage the protrusion 41 from the positioning groove 13, rotate it to the target angle, and then release it. Under the action of the spring 51, the protrusion 41 automatically engages in the corresponding positioning groove 13, achieving rapid angle locking. The operation is convenient and the positioning is stable.

[0028] In addition, combined Figure 1 and Figure 6As shown, a rotating shaft 7 is rotatably installed inside the hinge frame 4. The top of the camera 6 is sleeved on the outer surface of the rotating shaft 7. Pin holes 71 are opened through the outer surfaces of both ends of the rotating shaft 7, and positioning pins 72 are snapped into the pin holes 71.

[0029] The pivot 7 provides a pivot point for adjusting the pitch angle of the camera 6. The two ends of the pivot 7 are connected to the hinge frame 4 with clearance fit to ensure smooth rotation without jamming. The pin holes 71 at both ends of the pivot 7 cooperate with the positioning pins 72 to form an axial positioning structure. After the positioning pins 72 are engaged with the pin holes 71, they can restrict the pivot 7 from moving axially, preventing the camera 6 from falling off the pivot 7, while not affecting the rotation function of the pivot 7.

[0030] Combination Figure 1 and Figure 6 As shown, multiple damping pads 73 are provided between the top left and right surfaces of the camera 6 and the inner sidewall of the hinge frame 4. The damping pads 73 are all sleeved on the outer surface of the rotating shaft 7. The damping pads 73 are hard metal pads (steel ring pads or iron ring pads) and are sleeved on the rotating shaft 7 and clamped between the camera 6 and the hinge frame 4. Their core function is to provide rotational damping force, so that the camera 6 can be flipped to adjust the working angle, and can be kept at the adjusted angle to effectively resist the angle displacement caused by slight vibration and improve shooting stability.

[0031] Finally, to prevent rain from affecting the camera in severe weather, a stainless steel rain cover 8 needs to be fixedly installed on the outer surface of the articulation frame 4. The stainless steel rain cover 8 is an isosceles trapezoid with a closed rear end and a through-hole at the top that matches the size of the articulation frame 4. During production, the two are installed together by welding after being installed on the outer surface of the articulation frame 4 through the through-hole. The rain cover 8 can shield and guide rainwater, preventing rainwater from contacting the camera 6 in rainy weather and avoiding the problem of the camera 6's outer cover being affected by rainwater and unable to clean the captured image. In addition, the stainless steel rain cover 8 can rotate and adjust together with the articulation frame 4 and the camera 61, which is suitable for rain shielding after the camera 61 is adjusted.

[0032] Working principle: ① Component pre-assembly: First, the T-shaped hollow column 2, sleeve 3, and hinge frame 4 are pre-assembled. During pre-assembly, the T-shaped hollow column 2 is inserted through the inverted groove 11 of the L-shaped wall plate 1 to achieve sliding engagement with the sleeve 3. Then, the hinge frame 4 is inserted into the sleeve 3 from the bottom, and three internal hexagonal bolts 21 are screwed into the inner cavity of the T-shaped hollow column 2. The position of the sleeve 3 is then adjusted circumferentially so that the bolt heads of the internal hexagonal bolts 21 are engaged with the corresponding U-shaped blocks 52 in the mounting groove 31 on the inner side wall of the sleeve 3. This establishes a force transmission path of "T-shaped hollow column 2 → internal hexagonal bolts 21 → U-shaped blocks 52 → sleeve 3", laying the foundation for the subsequent function of the elastic tightening device 5. ② Angle pre-adjustment: After the components are pre-assembled, the hinge frame 4 is pulled down according to the shooting angle required for actual installation. At this time, the sleeve 3 moves down synchronously with the hinge frame 4, compressing the spring 51 in the mounting groove 31 to prevent structural jamming during subsequent angle adjustment. Then, by rotating the hinge frame 4, the sleeve 3 and the T-shaped hollow column 2 are driven to rotate circumferentially along the inverted groove 11 of the L-shaped wall panel 1, thereby adjusting the horizontal position of the camera 6 inside the hinge frame 4 until the camera 6 is adjusted to a suitable position that meets the shooting requirements. ③ Base fixing: After the camera 6 is positioned correctly, the L-shaped wall panel 1 with mounting holes is used as the core support. The L-shaped wall panel 1 is then attached to the target mounting surface such as the ceiling or bracket. Fasteners such as expansion bolts are passed through the mounting holes of the L-shaped wall panel 1 to secure it firmly to the mounting surface. During the fixing process, it is necessary to ensure that the L-shaped wall panel 1 is horizontal to avoid tilting the overall structure. After fixing, the spring 51 returns to its natural deformation, generating an upward elastic force. Through the U-shaped block 52 and the internal hexagonal bolt 21, the sleeve 3 slides upward along the T-shaped hollow column 2, so that the upper surface of the hinge frame 4 is tightly fitted with the positioning ring 12 on the lower surface of the L-shaped wall panel 1. The protrusion 41 of the hinge frame 4 is engaged with the positioning groove 13 of the positioning ring 12, thereby achieving automatic locking of the camera 6 angle.
