[0040] Wherein, in the present application, installation structure 100 can be ceiling or wall.

[0041] As Figure 1 And Figure 7 As shown, fixed assembly includes first fixed structure 31 and second fixed structure 32, first fixed structure 31 is detachably connected with first installation part, and first fixed structure 31 is used to fix inner cover 10 in first installation position, second fixed structure 32 is detachably connected with second installation part, and second fixed structure 32 is used to fix inner cover 10 in second installation position.

[0042] Thus, since the first fixing structure 31 and the second fixing structure 32 are respectively detachably connected with the first mounting portion and the second mounting portion, this design allows the inner cover 10 to be flexibly switched between the first mounting position and the second mounting position, meeting the diversified needs for the camera mounting mode in different scenarios, such as ceiling mounting and embedded mounting.

[0043] Optionally, when installing the mounting device, the first fixing structure 31 and the second fixing structure 32 can be fixed on the inner cover 10, and the staff can select the first fixing structure 31 and the second fixing structure 32 according to needs.

[0044] In this application, when installing the mounting device, the staff can select the first fixing structure 31 or the second fixing structure 32, and separately install the first fixing structure 31 and the second fixing structure 32 to the inner cover 10, so that the mounting device installed on the mounting structure 100 can be simplified, and the mounting device is convenient to install.

[0045] As shown in Figure 2 The first mounting portion includes a connecting piece 12, and the first fixing structure 31 includes a connecting flange 311. The connecting flange 311 is provided with a fixing hole 3111, the connecting piece 12 is arranged in the fixing hole 3111, and the connecting flange 311 and the inner cover 10 are detachably connected through the connecting piece 12 and the fixing hole 3111. The connecting flange 311 is used for detachable connection with the mounting structure 100.

[0046] Thus, the inner cover 10 is convenient to be installed on the mounting structure 100, and the combination of the connecting piece 12 and the fixing hole 3111 makes the installation and disassembly process extremely simple, and the mounting device can be quickly installed and disassembled without complex tools or technology, saving installation time and improving work efficiency.

[0047] In this application, the connecting flange 311 is provided with a locking hole 3113, and a screw is arranged in the locking hole 3113 to fix the connecting flange 311 on the mounting structure 100, so that the connecting flange 311 is convenient to be fixed.

[0048] Specifically, in this application, the connecting piece 12 is a screw.

[0049] As shown in Figure 2 The fixing hole 3111 has a penetrating portion and a fixing portion in communication with each other, the cross-sectional area of the penetrating portion is greater than that of the fixing portion, the connecting piece 12 can be arranged in the penetrating portion, and the connecting piece 12 can rotate relative to the fixing hole 3111. When the connecting piece 12 is located in the fixing portion, the inner cover 10 is fixed on the connecting flange 311 through the connecting piece 12 and the fixing hole 3111.

[0050] In this way, when the inner cover 10 is fixed to the connecting flange 311, the connecting piece 12 is first aligned with the penetrating part, and then the inner cover 10 is rotated so that the connecting piece 12 is located in the fixing part, so that the inner cover 10 can be pre-fixed to the connecting flange 311. At the same time, by using the above structure, the inner cover 10 can be prevented from falling off the connecting flange 311, and the reliability of the operation of the inner cover 10 is improved.

[0051] Further, in the present application, the first mounting part includes three connecting pieces 12, which are distributed at intervals in the circumferential direction, and the connecting flange 311 is provided with three fixing holes 3111, and the three connecting pieces 12 and the three fixing holes 3111 are arranged one by one, and the connecting piece 12 penetrates the corresponding fixing hole 3111.

[0052] The first fixing structure 31 further includes an outer cover 312, which covers the outer side of the inner cover 10, and the outer cover 312 is detachably connected with the inner cover 10. When the connecting piece 12 is located in the fixing part, the outer cover 312 and the connecting flange 311 are detachably connected through the locking piece 313.

[0053] By using the above structure, before the inner cover 10 is fixed to the connecting flange 311, the outer cover 312 is first sleeved on the outer side of the inner cover 10 and is fastened and connected by screws, and the inner cover 10 and the outer cover 312 are fastened and connected by three screws. After the inner cover 10 is pre-fixed to the connecting flange 311, the outer cover 312 and the connecting flange 311 are connected through the locking piece 313.

[0054] In this way, it is convenient to install the inner cover 10 and the outer cover 312, and it is convenient to fix the inner cover 10 to the connecting flange 311, and the installation and disassembly are convenient. At the same time, the outer cover 312 provides additional protection for the inner cover 10 and the internal components, enhances the environmental adaptability and durability of the equipment, and the detachable connection between the outer cover 312 and the connecting flange 311 realized by the locking piece 313 ensures that the outer cover 312 will not easily fall off after the equipment is installed, and the safety during use is improved.

[0055] Among them, the traditional installation method is to assemble the camera directly through screws to install the equipment on the ceiling, and the camera is extremely easy to fall off during installation. However, in the present application, the outer cover 312 is installed after the inner cover 10 is pre-fixed, which can reduce the difficulty of installation of the camera.

[0056] Among them, in the present application, the connecting flange 311 is provided with a connecting plate, and the inner cover 10 and the outer cover 312 have a clearance, and the connecting plate is rotatably arranged in the clearance, and the outer cover 312 and the connecting plate are fastened and connected by screws.

[0057] Further, the connecting flange 311 is provided with a connecting hole 3112 on the side away from the inner cover 10, and the connecting hole 3112 is used for detachable connection with the connecting support. In this way, the connecting hole 3112 can be connected with the external connecting support, and through the detachable connecting support, the installation height of the camera can be adjusted according to the actual installation environment and monitoring requirements, so as to ensure that the device can obtain the best monitoring angle and effect.

[0058] In the installation of the inner cover 10 and the outer cover 312, the mounting hole 13 of the opening 11 of the inner cover 10 is provided with a locking member 313, i.e. a screw, which is threadedly connected with the outer cover 312.

[0059] As shown in Figures 4 to 7 The opening 11 of the inner cover 10 is provided with a mounting hole 13, and the mounting hole 13 forms a second mounting portion. The second fixing structure 32 includes a mounting member 321 and a limiting structure 322.

[0060] The mounting member 321 is arranged in the mounting hole 13 and the through hole 110 of the mounting structure 100. The limiting structure 322 is threadedly connected with the mounting member 321, and the limiting structure 322 has a relative arrangement of a retracted state and a limiting state. When the limiting structure 322 is in the retracted state, the limiting structure 322 can be mounted to the inner side of the mounting structure 100 through the through hole 110 of the mounting structure 100. When the limiting structure 322 is in the limiting state, the limiting structure 322 abuts against the mounting structure 100, and the limiting structure 322 and the mounting member 321 cooperate to fix the inner cover 10 on the mounting structure 100.

[0061] In the present application, the mounting member 321 is a screw.

[0062] In this way, when the inner cover 10 is installed, the mounting member 321 is arranged in the mounting hole 13, and then the limiting structure 322 is fixed on the mounting member 321. The worker extrudes the limiting structure 322 so that the limiting structure 322 is in the retracted state, and the limiting structure 322 and the mounting member 321 pass through the through hole 110 so that the mounting member 321 is arranged in the through hole 110, and the limiting structure 322 is mounted to the inner side of the mounting structure 100, thereby realizing the pre-fixing of the inner cover 10. After the limiting structure 322 is mounted to the inner side of the mounting structure 100, the limiting structure 322 abuts against the inner cover 10, and the rotating mounting member 321 can tighten the mounting member 321 to realize the fixing of the inner cover 10.

[0063] When the mounting device is disassembled, the ball cover structure 20 can be separated from the inner cover 10 first, and then the mounting member 321 and the inner cover 10 are separated, the inner cover 10 is taken off from the mounting structure 100, and finally the limiting structure 322 is taken off.

[0064] In this way, the embedded installation can avoid the device protruding from the surface of the ceiling panel to occupy space, and protect the space permeability. In addition, the above structure can make the installation more reliable and convenient.

[0065] As shown in Figure 7 and Figure 8 , the limiting structure 322 includes a fixing member 3221, a first support 3222, a second support 3223, and an elastic member 3224. The fixing member 3221 is threadedly connected with the mounting member 321. The first support 3222 and the second support 3223 are respectively located on both sides of the fixing member 3221, and the first support 3222 and the second support 3223 are both hingedly connected with the fixing member 3221. The elastic member 3224 is arranged between the fixing member 3221 and the first support 3222 and the second support 3223, and the elastic member 3224 can drive the first support 3222 and the second support 3223 to move away from each other, so that the limiting structure 322 is switched from the retracted state to the limiting state.

[0066] In this way, the first support 3222 and the second support 3223 are hingedly connected with the fixing member 3221 and driven by the elastic member 3224, and can be switched between the retracted state and the limiting state. This design provides flexibility during installation and is more convenient to operate. Since the first support 3222 and the second support 3223 can be automatically driven by the elastic member 3224 to switch states, this greatly simplifies the installation and disassembly process. During installation, only the limiting structure 322 needs to be positioned, and the elastic member 3224 automatically drives the supports to open, achieving quick fixing.

[0067] In addition, in the present application, the elastic member 3224 is located between the first support 3222 and the second support 3223 and the mounting structure 100. In this way, the limiting structure 322 will not be switched to the limiting state due to the gravity of the inner cover 10 and the ball cover structure 20, ensuring the reliability of the limiting structure 322 in operation. Therefore, the present application can be applied to the embedded installation of heavier equipment.

[0068] Specifically, the elastic member 3224 is a torsional spring, and the first support 3222 and the second support 3223 can be fixedly connected with both ends of the torsional spring, respectively.

[0069] As shown in Figure 2 , the inner cover 10 is provided with a first wire outlet hole 14, and the first wire outlet hole 14 is arranged on one side of the inner cover 10. The outer cover 312 is provided with a second wire outlet hole 3121, and the second wire outlet hole 3121 is arranged close to the first wire outlet hole 14. The first wire outlet hole 14 and the second wire outlet hole 3121 are used for passing through the connecting wire.

[0070] In the prior art, the device threading can only pass through the ceiling, and the cable needs to be reserved in advance in the ceiling, which has high requirements for device wiring.

[0071] But in this application, the first outlet hole 14 on the inner cover 10 is designed on the edge, and the second outlet hole 3121 on the outer cover 312 is reserved, which can realize side outlet, without wiring in the ceiling, and the wiring mode can be selected according to the actual situation during installation. That is, the cable can be directly led out from the first outlet hole 14, or sequentially led out through the first outlet hole 14, the gap between the connecting flange 311 and the outer cover 312, and the second outlet hole 3121.

[0072] As shown in Figure 1 The ball cover structure 20 includes a connecting disc 22 and a body 23. The connecting disc 22 is detachably connected with the inner cover 10. The body 23 is arranged on the side of the connecting disc 22 away from the inner cover 10, and the body 23 is detachably connected with the connecting disc 22.

[0073] In this way, the detachable connection design of the connecting disc 22 with the inner cover 10 and the body 23 with the connecting disc 22 makes it easy to disassemble the ball cover structure 20 during maintenance and upgrading, without the need to disassemble the entire camera. This provides convenience for replacing the lens, cleaning the ball cover, or repairing internal components, and reduces maintenance cost and time.

[0074] Specifically, in this application, the inner cover 10 and the connecting disc 22 can be connected by screws, and the body 23 and the connecting disc 22 can be connected by screws or other ways.

[0075] Another embodiment of the utility model provides a camera, the camera includes the installation device provided by the above. Because the installation device designs the structure compatible with the ceiling mounting and the embedded mounting, the camera can select the most suitable installation mode according to the actual application scene and environmental conditions. At the same time, the installation process is simplified, whether it is installation or disassembly, it is more time-saving and labor-saving than the traditional way, and the installation efficiency is improved.

[0076] Optionally, in other embodiments, a lighting structure can be placed in the placement cavity 21 of the installation device to assemble a lighting device.
