In addition, the skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of different embodiments or examples without contradiction.

[0045] Currently, there are two schemes for connecting the adapter ring with the camera. The first scheme is that the ball camera is fixed on the support through the adapter ring, the adapter ring is fastened with the support through screwing, and the adapter ring is prevented from loosening through the locking screw. The ball camera and the adapter ring are fastened through three screws which are punched into the recessed groove of the quick mounting connector of the ball camera from the outer shell of the adapter ring. However, in a high-intensity vibration environment, the recessed groove of the quick mounting connector of the ball camera is easily deformed by the impact of the three locking screws, which causes the ball camera and the quick mounting connector to be loose and the fastening function to fail. The second scheme is that the adapter ring is designed with multiple evenly distributed "7" shaped notches, and the same number of screws are fixed on the mounting connector of the ball camera. When the ball camera is installed, the screws on the mounting connector are hung in the notches of the adapter ring, and then the screws are locked to fix the ball camera and the adapter ring. In this scheme, the screws of the mounting connector of the ball camera are hung on the hooks of the adapter ring, and the vertical degree of freedom is limited by the gravity of the ball camera and the friction between the screws and the surface of the adapter ring. When the vibration environment provides a certain horizontal acceleration to the ball camera, the ball camera is subjected to a horizontal inertial force, which forms an upward and downward force at the mounting connector. The hooks of the adapter ring cannot form a downward thrust to resist the upward force of the mounting connector, and the friction between the screws and the adapter ring is also very limited. Therefore, the screws are easily detached from the hooks of the adapter ring, which causes the fixing structure to fail.

[0046] Although the above two installation schemes can reduce the installation difficulty of the camera, they cannot ensure the installation reliability in the vibration environment. Therefore, how to improve the installation reliability of the camera while reducing the installation difficulty of the camera is an urgent problem to be solved in the industry.

[0047] To solve the above problems, the utility model provides a kind of adapter fixing structure. The adapter fixing structure can be used to install camera main body on wall-mounted support or suspension support, but is not limited to install camera main body on wall-mounted support or suspension support. The following will be described in detail in combination with Figures 1 to 10 The adapter fixing structure of the utility model will be described in detail.

[0048] As Figures 1 to 10 As shown in the figure, the first aspect of the embodiment of the utility model provides a kind of adapter fixing structure. The adapter fixing structure includes fixed connector 100, adapter ring 200 and second limiting assembly 400. Fixed connector 100 includes connector body 110 and fixed sleeve 120;Connector body 110 is used to be connected with camera main body;The surface hardness of fixed sleeve 120 is greater than the surface hardness of connector body 110;Fixed sleeve 120 is sleeved on the outer side of connector body 110 away from the one end of camera main body, and is connected with connector body 110. Adapter ring 200 is sleeved on the outer side of fixed sleeve 120, and is connected with fixed sleeve 120.

[0049] In the embodiment, the fixing joint 100 is provided with the joint body 110 and the fixing sleeve 120, and the surface hardness of the fixing sleeve 120 is greater than that of the joint body 110, so that the strength of the fixing joint 100 can be improved, the collapse of the fixing joint 100 in a vibrating environment can be prevented, and the installation reliability of the camera can be improved. In addition, the adapter ring 200 is sleeved on the outer side of the fixing sleeve 120 and connected with the fixing sleeve 120, so that the installation efficiency of the camera body can be improved, and the installation difficulty can be reduced. Therefore, the adapter fixing structure of the embodiment can not only reduce the installation difficulty of the camera, but also improve the installation reliability of the camera, and solves the problem of poor installation reliability of the camera in the prior art.

[0050] Preferably, the joint body 110 is made of aluminum alloy, which can reduce the weight of the whole machine and the inertia force converted by the acceleration of the vibrating environment is smaller. The fixing sleeve 120 is a steel sleeve, which can resist the impact of the inertia force of the camera in a strong vibrating environment on the two, and the surface of the steel sleeve is not easy to collapse or deform, so that the installation reliability of the whole machine is significantly improved.

[0051] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 10 , in some embodiments, the adapter fixing structure further comprises a second limiting assembly 400; the second limiting assembly 400 is installed on the adapter ring 200, the second limiting assembly 400 abuts against the outer side of the fixing sleeve 120, and is used to extrude the fixing sleeve 120 along the radial direction of the adapter ring 200, so that the adapter ring 200 and the fixing sleeve 120 are limited and matched along the radial direction of the adapter ring 200.

[0052] In the embodiment, the second limiting assembly 400 is installed on the adapter ring 200 and abuts against the outer side of the fixing sleeve 120, and the second limiting assembly 400 is used to extrude the fixing joint 100 along the radial direction of the adapter ring 200, so that the adapter ring 200 and the fixing sleeve 120 are limited and matched along the radial direction of the adapter ring 200, the fixing joint 100 and the adapter ring 200 can be prevented from being separated, the fixing joint 100 and the adapter ring 200 can be assembled together even in a strong vibrating environment, and the installation reliability of the camera is improved.

[0053] Further, the second limiting assembly 400 comprises a plurality of top pressing blocks 410 and a fastener 420. The side wall of the adapter ring 200 is provided with a plurality of mounting holes 210, which are arranged along the circumference of the adapter ring 200. The plurality of top pressing blocks 410 are arranged in the mounting holes 210 one by one, and the inner side surface of the top pressing block 410 abuts against the outer side surface of the fixing sleeve 120. The fastener 420 is sleeved on the outer side surface of the adapter ring 200 and abuts against the outer side surface of the top pressing block 410, and is used to press the top pressing block 410 towards the fixing sleeve 120 along the radial direction of the adapter ring 200.

[0054] In the embodiment, the top pressing blocks 410 are arranged along the circumference of the adapter ring 200, so that the pressing of the fixing sleeve 120 can be achieved from different positions. By arranging the fastener 420, the fastener 420 is sleeved on the outer side surface of the adapter ring 200 and abuts against the top pressing block 410, so that the pressing of all the top pressing blocks 410 can be achieved by using the same fastener 420. The structure of the second limiting assembly 400 is simplified, the operation convenience is improved, the installation speed is improved, and the installation difficulty is reduced.

[0055] In addition, in the embodiment, the inner side surface of the top pressing block 410 abuts against the outer side surface of the fixing sleeve 120, that is, the top pressing block 410 of the embodiment is in surface contact with the fixing sleeve 120. When the friction force is constant, the larger the contact surface is, the smaller the surface pressure is, and the contact is less likely to be damaged. At present, a fastening screw is usually arranged on the adapter ring 200, and the fastening screw is in point contact with the fixing joint. Compared with the point contact of the traditional fastening screw, the embodiment is less likely to cause the problem that the fixing sleeve 120 and the adapter ring 200 are crushed, and further prevents the problem of impact deformation.

[0056] As shown in FIGS. Figure 7 and Figure 8 Further, along the radial direction of the adapter ring 200, the top pressing block 410 is rotationally fitted with the mounting hole 210; along the axial direction of the adapter ring 200, the top pressing block 410 is limitingly assembled with the mounting hole 210; and the outer side surface of the top pressing block 410 is an inclined surface. In other words, the top pressing block 410 can rotate inwardly or outwardly in the mounting hole 210. By arranging the top pressing block 410 which is rotationally fitted with the mounting hole 210 along the radial direction of the adapter ring 200 and is limitingly fitted with the mounting hole 210 along the axial direction of the adapter ring 200, and by designing the outer side surface of the top pressing block 410 as an inclined surface, when the outer side surface of the top pressing block 410 is subjected to downward pressure, the top pressing block 410 can convert a part of the downward pressure into a radial and inward thrust along the adapter ring 200, and the top pressing block 410 rotates inwardly immediately, so that the inner side surface of the top pressing block 410 is pressed against the outer side surface of the fixing sleeve 120, a friction force is generated, and the relative movement between the fixing sleeve 120 and the adapter ring 200 is prevented, so as to achieve the purpose of locking and effectively prevent the fixing sleeve 120 and the adapter ring 200 from loosening in a vibration environment.

[0057] As shown in Figure 7 , preferably, the first included angle a between the outer side of the tight block 410 and the radial direction of the adapter ring 200 is 70° to 85°. In the case that the downward pressure on the outer side of the tight block 410 is fixed, more pressure can be converted into the radial and inward thrust of the adapter ring 200, further improving the locking effect and the installation reliability of the camera.

[0058] As shown in Figure 7 and Figure 8 , the tight block 410 includes a tight head 411 and a rotating shaft 412. The rotating shaft 412 is arranged at the end of the tight head 411 away from the camera body, and is rotationally fitted with the mounting hole 210 along the axial direction of the adapter ring 200. The tight head 411 is movably arranged in the mounting hole 210. The outer side of the tight head 411 is an inclined surface and abuts against the fastener 420. The inner side of the tight head 411 abuts against the outer side of the fixed joint 100. When the tight head 411 is subjected to downward pressure, the tight head 411 immediately rotates inward along the rotating shaft 412, so that the inner side of the tight head 411 always abuts against the outer side of the fixed joint 100, forming a frictional force limitation, so that the fixed joint 100 and the adapter ring 200 cannot move relative to each other, achieving the locking purpose.

[0059] It can be understood that the tight block 410 is installed in the mounting hole 210 from the outside of the adapter ring 200.

[0060] Further, the fastener 420 includes a compression nut or a clamp.

[0061] As shown in Figure 10 , specifically, the adapter ring 200 has a compression nut mounting surface 220. When the compression nut is threadedly fitted with the adapter ring 200, the lower end surface of the compression nut abuts against the compression nut mounting surface 220. The inner side of the compression nut abuts against the outer side of the tight block 410 to press the tight block 410 towards the outer side of the fixed sleeve 120.

[0062] Specifically, the clamp is sleeved on the outer side of the adapter ring 200, and the inner side of the clamp abuts against the outer side of the tight block 410 to press the tight block 410 towards the outer side of the fixed sleeve 120.

[0063] As shown in Figure 3 , Figure 4 and Figure 6As shown, in some embodiments, the adapter fixing structure further comprises a first limiting assembly 300; the fixing sleeve 120 is slidably fitted with the adapter ring 200 along the circumference of the adapter ring 200 and is axially limitedly assembled with the adapter ring 200 through the first limiting assembly 300. By setting the first limiting assembly 300, not only can the fixing sleeve 120 and the adapter ring 200 be axially limited, in other words, prevent the fixing sleeve 120 and the adapter ring 200 from separating along the axial direction of the adapter ring 200; but also the adapter ring 200 and the fixing sleeve 120 can relatively slide along the circumference of the adapter ring 200, which can adjust the orientation of the camera according to actual needs, and is suitable for the case where the radio transmitting unit of the camera or the trademark of the camera has orientation requirements. After the orientation of the camera is completed, the tight block 410 is installed into the mounting hole 210 from the outside of the adapter ring 200, and finally the compression nut is threadedly assembled on the adapter ring 200 from top to bottom until the lower end surface of the compression nut contacts the compression nut mounting surface 220. At this time, the inner side surface of the compression nut abuts against the outer side surface of the tight top 411, so as to press the tight block 410 towards the outer side surface of the fixing sleeve 120, thereby achieving the purpose of locking the fixing sleeve 120 and the adapter ring 200.

[0064] As shown in Figure 4 and Figure 6 Further, the first limiting assembly 300 comprises a limiting groove 310 and a plurality of limiting protrusions 320; the limiting protrusions 320 and the limiting grooves 310 are slidably fitted along the circumference of the adapter ring 200 and are axially limitedly fitted; one of the limiting protrusions 320 and the limiting grooves 310 is arranged on the outer side surface of the fixing joint 100, and the other is arranged on the inner side surface of the adapter ring 200.

[0065] In this embodiment, the limiting protrusions 320 and the limiting grooves 310 which can be slidably fitted along the circumference of the adapter ring 200 are arranged, and when the limiting protrusions 320 are assembled in the limiting grooves 310, the limiting protrusions 320 and the limiting grooves 310 are axially limited, so that the fixing joint 100 can adjust the orientation of the camera according to actual needs before being locked by the second limiting assembly 400, which is suitable for the case where the radio transmitting unit of the camera or the trademark of the camera has orientation requirements.

[0066] Further, the inner side surface of the adapter ring 200 is formed with a limiting groove 310 along the circumferential direction of the adapter ring 200, and part of the tight top block 410 is located in the limiting groove 310, and the inner side surface of the tight top block 410 is in sliding fit with the limiting protrusion 320 along the circumferential direction of the adapter ring 200. Specifically, the tight top part 411 is located in the limiting groove 310, and the inner side surface of the tight top part 411 is in sliding fit with the limiting protrusion 320 along the circumferential direction of the adapter ring 200. This can avoid the tight top block 410 from being stuck with the limiting protrusion 320, and ensure that the whole machine can rotate along the limiting groove 310. In addition, this way of designing part of the tight top block 410 to be located in the limiting groove 310 can also reduce the overall volume of the adapter fixing structure, thereby reducing the overall weight.

[0067] As shown in Figure 8 Further, the inner side surface of the tight top block 410 is formed by splicing the tight surface 413 and the tight side surface 414 located on both sides of the tight surface 413, and the tight surface 413 is in abutment with the outer side surface of the fixed joint 100. The second included angle β formed by the two tight side surfaces 414 is 90° to 120°. Designing the inner side surface of the tight top block 410 by splicing the tight surface 413 and the tight side surface 414 located on both sides of the tight surface 413, and limiting the second included angle β formed by the two tight side surfaces 414 to be 90° to 120°, not only can reduce the processing difficulty, but also can ensure that the tight top block 410 will not be stuck with the limiting protrusion 320 when the limiting protrusion 320 slides along the limiting groove 310.

[0068] As shown in Figure 8 Specifically, the inner side surface of the tight top part 411 is formed with a tight protrusion; part of the tight protrusion is located in the limiting groove 310, and the tight protrusion is in the form of a trapezoid in the radial cross section of the adapter ring 200; the side of the tight protrusion away from the tight top block 410 includes the tight surface 413 and the two tight side surfaces 414; the two tight side surfaces 414 are located on both sides of the tight surface 413, and the second included angle β formed by the two tight side surfaces 414 is 90° to 120°. By designing the tight protrusion to be in the form of a trapezoid, the processing difficulty can be reduced. By limiting the second included angle β formed by the two tight side surfaces 414 to be 90° to 120°, it can be ensured that the tight protrusion will not be stuck with the limiting protrusion 320 when the limiting protrusion 320 slides along the limiting groove 310.

[0069] Illustratively, the tight surface 413 and the two tight side surfaces 414 are all formed with arc surfaces.

[0070] Illustratively, the tight protrusion is in the form of a sector in the radial cross section of the adapter ring 200, and the side of the tight protrusion away from the tight top block 410 is in the form of an arc surface.

[0071] As shown in Figure 9As shown, further, the fixing sleeve 120 is threadedly assembled with the joint body 110, which can improve the connection stability and reliability. Specifically, the outer side surface of the fixing sleeve 120 is formed with a plurality of limiting protrusions 320, which are arranged along the circumference of the fixing sleeve 120. The inner side surface of the adapter ring 200 is formed with limiting grooves 310 along the circumference of the adapter ring 200, and the limiting protrusions 320 are slidably fitted with the limiting grooves 310 along the circumference.

[0072] Further, the fixing sleeve 120 is assembled with the joint body 110 by means of fasteners, which can improve the connection stability and reliability. Specifically, the end of the fastener away from the fixing sleeve 120 protrudes from the outer side surface of the fixing sleeve 120 to serve as the limiting protrusion 320. The inner side surface of the adapter ring 200 is formed with limiting grooves 310 along the circumference of the adapter ring 200, and the limiting protrusions 320 are slidably fitted with the limiting grooves 310 along the circumference.

[0073] Specifically, the side wall of the fixing sleeve 120 is provided with a plurality of first threaded holes; the plurality of first threaded holes are arranged along the circumference of the fixing sleeve 120; the joint body 110 is provided with a plurality of second threaded holes, which correspond one-to-one with the plurality of first threaded holes. The fastener includes a lug screw, which is threadedly assembled in the first threaded hole and the second threaded hole. At this time, the end of the lug screw away from the fixing sleeve 120 protrudes from the outer side surface of the fixing sleeve 120, which is equivalent to the limiting protrusion 320. The lug screw not only fastens the fixing sleeve 120 and the joint body 110, but also slidably fits with the limiting grooves 310 formed on the inner side surface of the adapter ring 200 along the circumference of the adapter ring 200.

[0074] In some other embodiments, the number of the second limiting assemblies 400 is a plurality, and the plurality of second limiting assemblies 400 are arranged along the circumference of the adapter ring 200 at different positions and press the fixed joint 100 along the radial direction of the adapter ring 200, which further improves the reliability of the limiting fit between the adapter ring 200 and the fixed joint 100 in the radial direction.

[0075] Specifically, the second limiting assembly 400 includes a compression spring and a support rod; the support rod is vertically installed on the outer side surface of the adapter ring 200, and the compression spring is horizontally arranged, with one end connected to the support rod and the other end abutting against the outer side surface of the fixed joint 100 through the side wall of the adapter ring 200 along the radial direction of the adapter ring 200. The compression direction of the compression spring is parallel to the radial direction of the adapter ring 200. Specifically, the compression direction of the compression spring is the horizontal direction, and the radial direction of the adapter ring 200 is also the horizontal direction.
