The base secures the bracket and provides stability, the support arm connects the base and the pan / tilt head, and the pan / tilt head connects the bracket arm and the camera, supporting multi-angle rotation. However, when encountering uneven walls or drilling holes in the wall, gaps may appear at the edges of the drilled holes. When fixing the base of the mounting bracket, these gaps in the wall cannot provide support, leading to loosening of the base over time. Summary of the Invention

[0004] This application proposes a network camera mounting bracket that has the advantage of automatically compensating for wall recesses and gaps, thereby solving the problem that the base cannot be effectively supported due to uneven walls or gaps at the edges of drilled holes.

[0005] To achieve the above objectives, this application adopts the following technical solution: a network camera mounting bracket, including a base, a support arm, a pan-tilt unit, and fixing bolts. The base has several mounting holes. The pan-tilt unit includes a rotating block and a mounting block. The support arm contains: a support spring, fixedly connected to one end of the support arm away from the base; a support rod, fixedly connected to the other end of the support spring and slidably disposed within the support arm, the support rod having an elongated groove I; and several movable pads, slidably disposed within the support arm near one end of the base. The base has: several pad grooves, located on the side of the base away from the support arm; and a sliding groove, located within the base and connecting the support arm and the pad grooves.

[0006] Furthermore, the base is provided with: a protruding bladder, which is embedded in the edge of the bottom of the groove; and several expansion bladders, which are embedded in the end face of the base away from the support arm and are coaxially installed with the protruding bladder, and the expansion bladders on the same axis are connected to the protruding bladder.

[0007] Furthermore, the support spring is always in a compressed state.

[0008] Furthermore, the movable pad is a polygonal permanent magnet, and a through hole is provided at the center of the movable pad.

[0009] Furthermore, the upper end faces of the support rod on both sides of the fixing bolt are symmetrically provided with inclined grooves, and the end face of the rotating block that contacts the support arm is provided with an arc-shaped rotating groove; a support column is inserted into the rotating groove, the bottom end of the support column passes through the support arm and extends into the inclined groove, one side of the support column contacts the bottom end of the inclined groove, the other side of the support column contacts the top end of the inclined groove, and the top end of the support column abuts against the bottom end of the mounting block, and the support column is used to support the mounting block.

[0010] Furthermore, a fixing post is fixedly connected to the side wall of the elongated groove I near the supporting spring. The fixing bolt is provided with: a fixing hole, which is opened in the side wall of the fixing bolt, and the axis of the fixing post is on the same straight line as the center of the fixing hole; a pressing hole, which is opened in the fixing bolt above the fixing hole; a pressing post, which is slidably installed in the pressing hole; and several sliders, which are inserted into the side wall at the top of the pressing hole and penetrate through the side wall of the fixing bolt. The side wall of the hole for mounting the fixing bolt of the rotating block is provided with several fixing grooves arranged in a ring array.

[0011] Furthermore, the end of the fixing column pointing towards the fixing bolt is a pointed tip, the top and bottom ends of the extrusion column are chamfered, and the surface of the slider near the extrusion column is an inclined surface.

[0012] Furthermore, a permanent magnet is embedded at one end of the slider near the axis of the fixing bolt, and the permanent magnets on the slider generate a magnetic force that attracts each other.

[0013] Furthermore, the side wall of the support arm is provided with an elongated groove II, and the support rod is provided with a through movable hole. When the support rod slides inside the support arm, the movable hole is always connected to the elongated groove II.

[0014] This application has the following beneficial effects:

[0015] 1. The network camera mounting bracket provided in this application slides the movable pads inside the base to the pad grooves, so that different numbers of movable pads are placed in several pad grooves. By using the different thicknesses of the movable pads in each pad groove, the recesses of the wall or the gaps at the edges of the holes drilled in the wall are compensated, so that the mounting holes of the base can be supported by the wall, preventing the base from loosening after long-term use.

[0016] 2. The network camera mounting bracket provided in this application, during the process of pushing the movable pad into the pad groove, the movable pad squeezes the bulge, thereby causing the gas in the bulge to enter the expansion bladder, causing the expansion bladder to stretch and further squeeze the wall, thereby sealing the gap at the edge of the wall hole, preventing rainwater from entering the hole in the wall from the gap at the edge of the wall hole, thereby avoiding the expansion bolts used for installation from being corroded by rainwater.

[0017] 3. The network camera mounting bracket provided in this application, during the process of pushing the movable pad into the pad groove, the support spring pushes the support rod to move towards the base, thereby changing the support point of the inclined groove in the support rod to the support column. By adjusting the number of movable pads entering the pad groove, the support point of the inclined groove to the support column is adjusted, thereby changing the tilt angle of the mounting block. Furthermore, the angle of the mounting block is fixed by the support column to prevent the mounting block from rotating due to the gravity of the network camera, thereby avoiding changes in the camera angle.

[0018] 4. The network camera mounting bracket provided in this application, during the process of pushing the movable pad into the pad groove, the support spring pushes the support rod to move towards the base, and the support rod drives the fixed column in the elongated groove I to move synchronously, so that the fixed column is inserted into the fixing hole of the fixing bolt, pushing the extrusion column to move upward, the extrusion column extrudes the slider, so that the slider extends into the fixing groove, thereby fixing the rotating block with the slider, preventing the network camera from swaying significantly when subjected to strong winds, thus affecting the shooting angle of the network camera.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] Please see Figure 1 A network camera mounting bracket includes a base 1, a support arm 2, a pan-tilt head 3, and fixing bolts 4. The base 1 has several mounting holes 11. The support arm 2 is fixedly mounted at the middle position of one side of the base 1. The pan-tilt head 3 is mounted on the upper end of the support arm 2 away from the base 1 by fixing bolts 4. The pan-tilt head 3 includes a rotating block 31 and a mounting block 32. The middle of the rotating block 31 is mounted on the support arm 2 by fixing bolts 4. The mounting block 32 is mounted to the rotating block 31 by a hinge shaft. The upper end of the mounting block 32 is used to mount the network camera.

[0032] Please see Figures 1-4The support arm 2 is a hollow tube. A support spring 21 is fixedly connected to one end of the support arm 2 away from the base 1. A support rod 22 is fixedly connected to the other end of the support spring 21, and the support rod 22 is slidably disposed within the support arm 2. An elongated groove I 25 is formed on the support rod 22, and the elongated groove I 25 is movably fitted onto the outside of the fixing bolt 4. Several movable washers 23 are slidably installed at one end of the support arm 2 near the base 1. Several pad grooves 12 are formed on the side of the base 1 away from the support arm 2. The axis of the pad groove 12 is collinear with the axis of the mounting hole 11. A connection is formed within the base 1 that links the support arm 2 and the pad grooves 12. The sliding groove 13 allows the movable pad 23 to slide within it and into the pad groove 12. This secures the base 1. When encountering a recess in the wall or a notch at the edge of a hole in the wall, the movable pad 23 near the base 1 slides through the sliding groove 13 into the pad groove 12 corresponding to the wall recess. The number of movable pads 23 in the pad groove 12 varies depending on the depth of the wall recess, allowing the movable pads 23 to compensate for the wall recess or the notch at the edge of the hole. This ensures that all mounting holes 11 of the base 1 are supported by the wall, preventing the base 1 from loosening after prolonged use.

[0033] Please see Figures 2-4 The bottom edge of the groove 12 is embedded with a bulge 14, and several expansion bladders 15 are embedded on the end face of the base 1 away from the support arm 2. The expansion bladders 15 and the bulges 14 are coaxially installed, and the expansion bladders 15 on the same axis are connected to the bulges 14. During the process of pushing the movable pad 23 into the groove 12, the movable pad 23 squeezes the bulges 14, so that the gas in the bulges 14 enters the expansion bladders 15, so that the expansion bladders 15 extend further toward the wall, thereby sealing the gap at the edge of the hole in the wall and preventing rainwater from entering the hole in the wall from the gap at the edge of the hole, thus avoiding the expansion bolts used for installation from being corroded by rainwater.

[0034] The support spring 21 is always in a compressed state; the compressed support spring 21 exerts a supporting force on the support rod 22. After the movable pad 23 near the base 1 slides out of the slide groove 13, the supporting force of the support spring 21 pushes the support rod 22 and the movable pad 23 toward the base 1 to replenish the movable pad 23.

[0035] The movable pad 23 is a polygonal permanent magnet with a through hole in the center. Multiple movable pads 23 can automatically attract each other to prevent them from falling out of the groove 12. When using the movable pads 23 to compensate for recesses or gaps at the edges of holes in the wall, the movable pads 23 can rotate according to the shape of the gap, making the compensation of the gap by the movable pads 23 more stable.

[0036] The working principle of Embodiment 1 of the present invention is as follows:

[0037] Please see Figures 1-4 The base 1 is fixed. When there is a recess in the wall or a gap at the edge of the hole in the wall, the movable pad 23 near the base 1 is slid through the slide 13 into the pad groove 12 corresponding to the recess in the wall. The number of movable pads 23 in the pad groove 12 varies depending on the depth of the wall recess, so that the movable pads 23 can compensate for the recess in the wall or the gap at the edge of the hole in the wall. This ensures that the several mounting holes 11 of the base 1 can be supported by the wall, preventing the base 1 from becoming loose after long-term use.

[0038] During the process of pushing the movable shim 23 into the shim groove 12, the movable shim 23 compresses the bulge 14, thereby causing the gas in the bulge 14 to enter the expansion bladder 15, causing the expansion bladder 15 to extend further toward the wall, thereby sealing the gap at the edge of the hole in the wall and preventing rainwater from entering the hole in the wall through the gap at the edge of the hole, thus avoiding the expansion bolts used for installation from being corroded by rainwater.

[0039] Example 2

[0040] Example 2 is a further improvement based on Example 1.

[0041] Unlike Example 1, please refer to Figure 2 , Figure 5 and Figure 7 The support rod 22 has symmetrically opened inclined grooves 24 on the upper end faces of both sides of the fixing bolt 4. The rotating block 31 has an arc-shaped rotating groove 33 on the end face that contacts the support arm 2, and a support column 5 is inserted into the rotating groove 33. The bottom end of the support column 5 passes through the support arm 2 and extends into the inclined groove 24. One side of the support column 5 contacts the bottom end of the inclined groove 24, and the other side of the support column 5 contacts the top end of the inclined groove 24. The top end of the support column 5 abuts against the bottom end of the mounting block 32. The support column 5 is used to support the mounting block 32. During the process of adjusting the movable shim 23 to support the base 1, as... As the number of movable pads 23 decreases, the support spring 21 pushes the support rod 22 and movable pads 23 toward the base 1, changing the position of the support rod 22 within the support arm 2. This changes the support point of the inclined groove 24 on the support rod 22 to the support column 5. By adjusting the number of movable pads 23 entering the pad groove 12, the support point of the inclined groove 24 to the support column 5 is adjusted, thereby changing the tilt angle of the mounting block 32. Furthermore, the angle of the mounting block 32 is fixed by the support column 5 to prevent the mounting block 32 from rotating due to the gravity of the network camera, thus avoiding changes in the camera angle.

[0042] Please see Figure 2 , Figure 5 , Figure 6 and Figure 7A fixed post 26 is fixedly connected to the side wall of the elongated groove I 25 near the support spring 21. The end of the fixed post 26 pointing towards the fixed bolt 4 is pointed. A fixed hole 41 is opened on the side wall of the fixed bolt 4. The axis of the fixed post 26 and the center of the fixed hole 41 are on the same straight line. A locking block is fixedly installed on the side wall of the fixed bolt 4. The locking block is locked on the support arm 2 to prevent the fixed bolt 4 from rotating. A pressing hole 42 is opened in the fixed bolt 4 above the fixing hole 41. A pressing post 43 is slidably installed in the pressing hole 42. Both the top and bottom ends of the pressing post 43 are chamfered. Several sliders 44 are inserted into the side wall of the top of the pressing hole 42. The surface of the slider 44 near the pressing post 43 is inclined. The slider 44 passes through the side wall of the fixed bolt 4. The position of the slider 44 is close to the bottom wall of the support arm 2 with the rotating block 31. On the same plane, the sidewall of the hole for mounting the fixing bolt 4 on the rotating block 31 is provided with several fixing grooves 34 arranged in a ring array. The number of fixing grooves 34 is much greater than the number of sliders 44. During the process of pushing the movable pad 23 into the pad groove 12, the support spring 21 pushes the support rod 22 to move towards the base 1. The support rod 22 drives the fixing column 26 in the elongated groove I 25 to move synchronously, so that the fixing column 26 is inserted into the fixing hole 41 of the fixing bolt 4. The fixing column 26 pushes the extrusion column 43 to move upward. The upward extrusion column 43 extrudes the slider 44, so that the slider 44 extends into the fixing groove 34 of the rotating block 31, thereby fixing the rotating block 31 with the slider 44. This prevents the network camera from swaying significantly when exposed to strong winds, which would affect the shooting angle of the network camera.

[0043] A permanent magnet is embedded at one end of the slider 44 near the axis of the fixing bolt 4, and the permanent magnets on several sliders 44 generate a magnetic force that attracts each other. When the pressing column 43 is reset and moves downward, the permanent magnets on the slider 44 generate a magnetic force that attracts each other, ensuring that several sliders 44 move toward the axis of the fixing bolt 4, so that the slider 44 slides out completely from the fixing groove 34.

[0044] Please see Figure 1 and Figure 2 The side wall of the support arm 2 is provided with an elongated groove II 27, and the support rod 22 is provided with a through movable hole 28. When the support rod 22 slides in the support arm 2, the movable hole 28 is always connected to the elongated groove II 27. When the horizontal angle of the network camera needs to be adjusted, the movable rod is inserted into the elongated groove II 27 and the movable hole 28, and the support rod 22 is pulled to compress the support spring 21, so that the fixed column 26 slides out from the fixed hole 41, the compression column 43 and the slider 44 are reset, thereby releasing the lock of the slider 44 on the rotating block 31, so that the network camera can drive the rotating block 31 to rotate, and complete the horizontal angle adjustment of the network camera.

[0045] The working principle of Embodiment 2 of the present invention is as follows:

[0046] Please see Figures 1-7 During the process of adjusting the movable pad 23 to support the base 1, as the movable pad 23 decreases, the support spring 21 pushes the support rod 22 and the movable pad 23 to move towards the base 1, changing the position of the support rod 22 within the support arm 2, thereby changing the support point of the inclined groove 24 on the support rod 22 to the support column 5. By adjusting the number of movable pads 23 entering the pad groove 12, the support point of the inclined groove 24 to the support column 5 is adjusted, thereby changing the pitch angle of the mounting block 32. Furthermore, the angle of the mounting block 32 is fixed by the support column 5 to prevent the mounting block 32 from rotating due to the gravity of the network camera, thereby avoiding changes in the camera angle.

[0047] During the process of pushing the movable pad 23 into the pad groove 12, the support spring 21 pushes the support rod 22 to move towards the base 1. The support rod 22 drives the fixed column 26 in the elongated groove I 25 to move synchronously, so that the fixed column 26 is inserted into the fixing hole 41 of the fixing bolt 4. The fixed column 26 pushes the extrusion column 43 to move upward. The upward extrusion column 43 extrudes the slider 44, so that the slider 44 extends into the fixing groove 34 of the rotating block 31, thereby fixing the slider 44 to the rotating block 31 and preventing the network camera from swaying significantly when subjected to strong winds, thus affecting the shooting angle of the network camera.

[0048] When the horizontal angle of the network camera needs to be adjusted, a moving rod is inserted into the elongated groove II 27 and the moving hole 28, and the support rod 22 is pulled to compress the support spring 21, so that the fixed column 26 slides out of the fixed hole 41, and the compression column 43 and the slider 44 are reset, thereby releasing the lock of the slider 44 on the rotating block 31, so that the network camera can drive the rotating block 31 to rotate, and complete the adjustment of the horizontal angle of the network camera.
