In the camera provided by the embodiment of the utility model, when in installation, firstly, the installation seat 1 is installed on the installation surface such as a wall body or a ceiling, then the control clamping assembly 3 is in a first state, and the first buckle 31 on the camera body 2 is aligned with the annular clamping part 12 on the installation seat 1; after alignment, the first buckle 31 is buckled with the annular buckling part 12, the buckling component 3 is changed into a second state from the first state, at the moment, the camera body 2 cannot fall off from the mounting seat 1, and the camera body 2 can rotate around the axis of the annular buckling part 12 relative to the mounting seat 1 so as to adjust the shooting angle of the camera body 2; after the adjustment is completed, the first buckle 31 is pressed to the attached annular clamping portion 12 through the fastener 32, the clamping assembly 3 is changed from the second state to the third state, at this time, the clamping assembly 3 cannot move relative to the annular clamping portion 12, and the camera body 2 cannot rotate relative to the mounting seat 1 around the axis of the annular clamping portion 12, so that stability and reliability of the camera body 2 in the use process can be guaranteed.

When the shooting angle of the camera body 2 needs to be adjusted, the fastener 32 is loosened, the clamping assembly 3 is changed from the third state to the second state, and the camera body 2 can rotate around the axis of the annular clamping part 12 relative to the mounting seat 1; after the camera body 2 rotates to a preset angle, the first buckle 31 is pressed to the attaching annular clamping portion 12 again through the fastener 32, and the clamping assembly 3 is converted into a third state from the second state, so that the camera body 2 is fixed relative to the mounting seat 1.

The sphere 22 can rotate around the axis of the annular clamping part 12 along with the cover body 21 synchronously relative to the base 11, and can also independently rotate around the center of the sphere relative to the cover body 21 so as to adjust the shooting angle. In addition, the cover body 21, the first buckle 31, the base 11, the annular clamping part 12 and other structures can be made of hard structures such as metal, and the strength and the hardness are high, so that the strength of the camera can be ensured, and the connection reliability between the camera body 2 and the mounting seat 1 is ensured.

As shown in fig. 4 to 5, in one embodiment, the camera further includes a second buckle 5 that is disposed on the camera body 2 and can be engaged with the annular engaging portion 12, and the second buckle 5 and the engaging component 3 are arranged at intervals along the circumferential direction of the annular engaging portion 12.

The second buckle 5 and the clamping assembly 3 are arranged at intervals along the circumferential direction of the annular clamping portion 12, so that the stability and the reliability of connection between the camera body 2 and the mounting seat 1 can be improved, the camera body 2 is prevented from being inclined relative to the mounting seat 1 to influence the shooting effect of the camera, and meanwhile, the first buckle 31 and the annular clamping portion 12 can be prevented from being accidentally separated to cause the falling damage of the camera body 2.

In the illustrated embodiment, the number of the second buckles 5 is two, and the number of the engaging assemblies 3 is one, so that the mounting process can be prevented from being excessively complicated while the stability of the connection between the camera body 2 and the mounting seat 1 is ensured. Of course, in other embodiments, the number of the second buckles 5 may be one, three or more, and the number of the engaging assemblies 3 may be two, three or more, so long as it is ensured that the plurality of second buckles 5 can simultaneously engage with the annular engaging portion 12, and the engagement of the first buckle 31 with the annular engaging portion 12 is not affected; or, the camera may not be provided with the second buckle 5, and the number of the clamping assemblies 3 may be two, three or more, and the plurality of groups of the clamping assemblies 3 are arranged at intervals along the circumferential direction of the annular clamping portion 12, so as to ensure the stability and reliability of the connection between the camera body 2 and the mounting seat 1.

The second buckle 5 is provided with a first inclined plane 51, after the second buckle 5 is clamped with the annular clamping part 12 in the installation process, the camera body 2 can form an inclined angle with the installation seat 1 under the action of the first inclined plane 51, and then the clamping assembly 3 is clamped with the annular clamping part 12; the clamping assembly 3 can be separated from the annular clamping portion 12 in the disassembling process, so that an inclination angle is formed between the camera body 2 and the mounting seat 1, and then the second buckle 5 is separated from the annular clamping portion 12, so that the disassembling and assembling process of the camera is more convenient.

Further, the camera further includes a silicone member (not shown) disposed on the annular clamping portion 12, and in the third state, the fastener 32 compresses the first buckle 31 to be attached to the silicone member, and the second buckle 5 is also compressed to be attached to the silicone member. The silica gel piece can increase the frictional force between annular joint portion 12 and first buckle 31 and second buckle 5 for camera body 2 can't rotate for mount pad 1, thereby improves the stability of camera in the third state.

As shown in fig. 4 to 5, in the illustrated embodiment, the first catch 31 is rotatably disposed on the camera body 2 about a predetermined axis, and the first catch 31 is rotated in a predetermined direction (i.e., the +x direction as illustrated) to a second state, and is rotated in a reverse direction (i.e., the-X direction as illustrated) to a first state. The first buckle 31 is switched between the first state and the second state by rotating relative to the camera body 2, and the adjusting mode is simple and convenient and is convenient for the user to operate. In another embodiment, the first buckle 31 may be slidably disposed on the camera body 2 along the radial direction of the annular clamping portion 12, and the first buckle 31 may be slid to the second state in a direction approaching the center of the annular clamping portion 12 and slid to the first state in a direction separating from the center of the annular clamping portion 12.

The first buckle 31 is provided with a second inclined plane 311, and in the process of mounting the camera body 2 to the mounting seat 1, the annular clamping part 12 is propped against the second inclined plane 311, so that the first buckle 31 rotates from the second state to the first state along the-X direction, and after the annular clamping part 12 is separated from the second inclined plane 311, the first buckle 31 is controlled to return to the second state and is clamped with the annular clamping part 12. In this way, it is not necessary to manually control the first buckle 31 to be changed from the second state to the first state before installation, and the operation steps are simplified, so that the installation efficiency can be improved.

As shown in fig. 2, the engaging component 3 further includes a torsion spring 35, and two torsion arms of the torsion spring 35 are respectively limited to the first buckle 31 and the camera body 2. In the process of controlling the first buckle 31 to move from the second state to the first state, the annular clamping part 12 is in sliding fit with the second inclined surface 311 to overcome the elastic force of the torsion spring 35, so that the first buckle 31 rotates around a preset axis along the-X direction, the torsion spring 35 is subjected to torsional elastic deformation, and elastic potential energy is accumulated in the torsion spring 35; after the annular clamping portion 12 is separated from the second inclined surface 311, the elastic potential energy of the torsion spring 35 is released, the first buckle 31 rotates around the preset axis in the +x direction to the second state under the action of the torsional elasticity of the torsion spring 35, and the first buckle 31 is clamped with the annular clamping portion 12. In this way, during the installation process, the first buckle 31 does not need to be manually controlled to be changed from the first state to the second state, so that the operation is further simplified, and the installation efficiency is improved. In addition, the torsion spring 35 can also improve the stability of the first buckle 31 in the second state, and avoid the first buckle 31 accidentally rotating to the first state along the-X direction around the preset axis and separating from the annular clamping portion 12, thereby further ensuring the stability and reliability of the connection between the camera body 2 and the mounting seat 1.

As shown in fig. 2 and 5, the engaging component 3 further includes a push button 36 connected to the first buckle 31, where the first buckle 31 and the push button 36 are disposed on two sides of the preset axis, the cover 21 is provided with an avoidance hole, and the push button 36 exposes the camera body 2 from the avoidance hole. When the camera needs to be disassembled, the first buckle 31 is adjusted from the third state to the second state through the fastener 32, and then the push button 36 is manually pressed, so that the first buckle 31 and the push button 36 rotate to the first state around the preset axis along the-X direction, and the first buckle 31 is separated from the annular clamping part 12. This can facilitate the user to control the rotation of the first buckle 31 relative to the camera body 2, and the operation is convenient.

As shown in fig. 5 to 6, the fastener 32 is rotatably disposed on the camera body 2 about a predetermined axis and is screwed with the first buckle 31. Wherein, the axis of the fastener 32 coincides with the preset axis, the outer peripheral wall that the fastener 32 can be set to is provided with the bolt of external screw thread, the first buckle 31 is provided with the internal screw hole, the external screw thread of fastener 32 and the internal screw hole screw-thread fit of first buckle 31. The fastener 32 is threadedly engaged with the first catch 31 such that the first catch 31 is switched between the second state and the third state. Because the first buckle 31 is required to be always in a clamping state with the annular clamping part 12 when sliding close to or away from the annular clamping part 12 along the preset axis, the preset axis is vertical to the mounting seat 1, the fastening piece 32 is also vertical to the mounting seat 1, the adjusting end of the fastening piece 32 can deviate from the mounting seat 1 and expose the cover body 21, and the hand of a user cannot interfere with the mounting surface such as a wall body or a ceiling in the adjusting process, so that the user can conveniently adjust the fastening piece 32.

When the fastener 32 rotates along the-X direction, the fastener 32 is in threaded engagement with the first buckle 31, so that the first buckle 31 slides to a third state along a preset axis toward one side close to the annular clamping portion 12, and the first buckle 31 is tightly pressed and attached to the annular clamping portion 12. When the fastener 32 rotates along the +x direction, the fastener 32 is in threaded engagement with the first buckle 31, so that the first buckle 31 slides to a second state along a preset axis toward a side far away from the annular clamping portion 12, and a certain gap exists between the first buckle 31 and the annular clamping portion 12. In the second state, the first buckle 31 can rotate around the preset axis in the-X direction to the first state in synchronization with the fastener 32, so that the first buckle 31 is disengaged from the annular clamping portion 12.

As shown in fig. 3, 7 and 8, the engaging assembly 3 further includes a first rotation stop member 33 provided on the first buckle 31, and the camera further includes a second rotation stop member 4 provided on the camera body 2. When the fastener 32 rotates along the-X direction, the first buckle 31 slides to the third state along the preset axis towards the side close to the annular clamping portion 12, the first buckle 31 is pressed and attached to the annular clamping portion 12, and meanwhile, the first rotation stopping piece 33 abuts against the second rotation stopping piece 4 to limit the first buckle 31 to rotate along the-X direction. Like this, can avoid fastener 32 to rotate along-X direction when the fastener 32 rotates along-X direction along with fastener 32 synchronous along-X direction rotation, also can avoid first buckle 31 to rotate along-X direction by accident under the exogenic action simultaneously to lead to first buckle 31 to break away from with annular joint portion 12, further guarantee the stability and the reliability of camera body 2 and mount pad 1 connection under the third state. When the fastener 32 rotates along the +x direction, the first buckle 31 slides to the second state along the preset axis toward the side far away from the annular clamping portion 12, a certain gap exists between the first buckle 31 and the annular clamping portion 12, and meanwhile, the first rotation stopping member 33 is separated from the second rotation stopping member 4, so that the first buckle 31 can rotate along the-X direction.

As shown in fig. 8, the second rotation stopping member 4 is provided with a third inclined surface 41, when the first buckle 31 slides along the preset axis to the side close to the annular clamping portion 12, the first rotation stopping member 33 will abut against the third inclined surface 41, and due to the inclined arrangement of the third inclined surface 41, the third inclined surface 41 will push the first rotation stopping member 33 and the first buckle 31 against the side close to the center of the annular clamping portion 12, so as to improve the clamping strength between the first buckle 31 and the annular clamping portion 12.

As shown in fig. 2 and fig. 5, when the fastener 32 rotates, the fastener 32 is in threaded engagement with the first buckle 31, the first buckle 31 slides along a preset axis relative to the fastener 32, so as to avoid the fastener 32 from being separated due to an excessive sliding range of the first buckle 31, and the locking assembly 3 further includes a separation preventing member 34 disposed on the fastener 32, so as to limit the first buckle 31 from being separated from the fastener 32 along the preset axis. Also, the fastener 32 does not need to be completely screwed out of the cover 21 when adjusting the angle of the camera body 2, so that loss of parts can be avoided. The anti-falling piece 34 may be set to be a snap spring sleeved on the periphery of the fastener 32, or may be set to be a protrusion protruding on the outer surface of the fastener 32, so long as the sliding range of the first buckle 31 relative to the fastener 32 can be limited, and the novel embodiment is not specifically limited herein.

As shown in fig. 6, since the engaging component 3 needs to be changed from the third state to the second state when the shooting angle of the camera body 2 is adjusted, in order to avoid that the sphere 22 is separated from the cover 21 in the second state, the engaging component 3 further includes a limiting piece 37 disposed on the first buckle 31, and in the second state, the limiting piece 37 abuts against the sphere 22 to limit the sphere 22 from separating from the cover 21, thereby preventing the sphere 22 from being separated from the cover 21 and damaged when the angle of the camera body 2 is adjusted, and improving the safety of the camera.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
