[0050] Specifically, such as Figures 3-4As shown, the first rotating joint 3 comprises a first joint 31 and a second joint 32 fixedly connected, wherein the axis of the first joint 31 is perpendicular to the axis of the second joint 32, the first joint 31 is connected with the mounting shell 2, in this embodiment, the first joint 31 is provided as a cylinder, the second joint 32 is located at the end side wall of the first joint 31, both form an L shape, and the axis of the first joint 31 is parallel to the length direction axis of the mounting shell 2, so that the axis of the second joint 32 is perpendicular to the length direction axis of the mounting shell 2; correspondingly, the second rotating joint 4 comprises a third joint 41 and a fourth joint 42 fixedly connected, the end of the fourth joint 42 away from the third joint 41 is connected with the base 5, the axis of the third joint 41 is perpendicular to the axis of the fourth joint 42, in this embodiment, the fourth joint 42 is provided as a cylinder, the third joint 41 is located at the end side wall of the fourth joint 42 away from the base 5, both form an L shape, and the axis of the fourth joint 42 is perpendicular to the side wall of the base 5 close to the mounting shell 2; wherein the second joint 32 and the third joint 41 are rotatably connected, and both are detachably connected into a whole through the first fixing member to realize the adjustment of the shooting angle, wherein when the second joint 32 and the third joint 41 are connected, i.e. the connecting part of the two L shapes is connected, the outer diameter of the connecting part will not be greater than the outer diameter of the first joint 31 and the fourth joint 42, so that the outer diameter of the whole rotating joint will not be enlarged, and the structure is compact.

[0051] Specifically, as Figure 3 and 5As shown, the second joint 32 and the third joint 41 are provided with mounting grooves on the side walls close to each other, wherein the center of the mounting groove on the side wall of the second joint 32 is fixed with the first connecting column 33, the free end of the connecting column is provided with the positioning column 34 coaxial with the first connecting column 33, the center of the positioning column 34 is provided with a threaded hole extending to the connecting column; correspondingly, the center of the mounting groove on the side wall of the third joint 41 is fixed with the second connecting column 43, the side wall close to the first connecting column 33 of the second connecting column 43 is provided with the positioning groove 44 matched with the positioning column 34, the groove bottom of the positioning groove 44 is provided with a connecting hole penetrating through the outer side wall of the third joint 41; when connecting, only the first fixing member needs to pass through the connecting hole, the positioning groove 44 and be connected to the threaded hole in sequence, so as to connect the second joint 32 and the third joint 41 into one whole. When connecting the second joint 32 and the third joint 41 together through the first fixing member, the center positioning connection of the second joint 32 and the third joint 41 is realized by inserting the positioning column 34 into the positioning groove 44, and then the first fixing member is connected, which can be a bolt, the first fixing member is fastened on the third joint 41, so that the second joint 32 and the third joint 41 abut and connect to one whole, when the first fixing member is loosened, the second joint 32 and the third joint 41 no longer abut, at this time, the second joint 32 can be rotated relative to the third joint 41, so as to realize the adjustment of the shooting angle, and after the adjustment is completed, the first fixing member can be tightened.

[0052] Specifically, a plurality of first reinforcing ribs are arranged in the mounting groove of the second joint 32 and are connected with the first connecting column 33, so as to increase the use strength of the first connecting column 33, and similarly, a plurality of second reinforcing ribs are arranged in the mounting groove of the third joint 41 and are connected with the second connecting column 43, so as to increase the use strength of the second connecting column 43.

[0053] Specifically, a plurality of first adjusting teeth are arranged on the side wall of the second joint 32 close to the third joint 41, and the plurality of first adjusting teeth are circumferentially arranged around the first connecting column 33 and form a first adjusting tooth group 35, correspondingly, a plurality of second adjusting teeth are arranged on the side wall of the third joint 41 close to the second joint 32, and the plurality of second adjusting teeth are circumferentially arranged around the second connecting column 43 and form a second adjusting tooth group 45, the first adjusting tooth group 35 cooperates with the second adjusting tooth group 45 to adjust the relative rotation angle between the third joint 41 and the second joint 32, wherein rotating one adjusting tooth is equivalent to adjusting a fixed angle, and the fixed angle adjustment can be realized by rotating a certain number of adjusting teeth during the rotation process, and the stable rotation adjustment between the second joint 32 and the third joint 41 can be realized through the cooperation of the first adjusting tooth group 35 and the second adjusting tooth group 45, and the friction between them is increased. It can be known that during the adjustment process, the first adjusting tooth and the second adjusting tooth are still in contact although the first fixing member has been loosened, and the two can move relatively.

[0054] Specifically, such as Figure 6 As shown, the mounting shell 2 has a connector 23 at one end near the base 5. The rotation axis of the connector 23 is parallel to the axis of the length direction of the mounting shell 2. The connector 23 is inserted into the first connector 31 and detachably connected to the second fastener to form a whole, thereby realizing the detachable connection between the first connector 31 and the mounting shell 2. Thus, the first rotating connector 3 can be removed separately for replacement and maintenance.

[0055] Specifically, the connector 23 includes a coaxially arranged boss 231 and a first protrusion 232, both of which are cylindrical. The first connector 31 is also cylindrical. Furthermore, the mounting housing 2 has a first cylindrical groove 221 on its side wall near the base 5. The boss 231 is partially installed within the first cylindrical groove 221, and the two are coaxially arranged. The first protrusion 232 is fixedly installed on the side wall of the boss 231 near the base 5. A first annular mounting cavity is formed between the outer side wall of the boss 231 and the inner side wall of the first cylindrical groove 221. During connection... The boss 231 and the first protrusion 232 extend into the first connector 31. The end of the first connector 31 is inserted into the first annular mounting cavity with a clearance fit. Then, a second fixing member is used, so that the thread of the second fixing member passes through the outer wall of the first connector 31 and the end side wall abuts against the first protrusion 232, thereby connecting the first protrusion 232 and the first connector 31 into a whole. During disassembly, it is only necessary to loosen the second fixing member and then pull the connector 23 out of the first connector 31, which is simple and convenient. Specifically, the second fixing member can be a bolt. It can be seen that when the first protrusion 232 and the first connector 31 are not completely fixed by the first fixing member, the end of the first connector 31 can rotate circumferentially around the boss 231 in the first annular mounting cavity. Therefore, if there is a skew or other situation when the shooting end is installed in the mounting shell 2, the installation angle of the mounting shell 2 can be adjusted by rotating the first connector 31 relative to it, so that the mounting shell 2 and the shooting end are aligned. Specifically, the boss 231, the first protrusion 232 and the rear shell 22 inside the mounting shell 2 are integrally formed and are molded parts. Moreover, the central axis of the boss 231 and the first protrusion 232 is provided with a through hole and communicates with the inner cavity of the rear shell 22 to facilitate wiring.

[0056] Specifically, the outer side wall of the first extending part 232 is provided with a first inclined surface 234, and the small-diameter end of the first inclined surface 234 is farther away from the base 5 than the large-diameter end. The end of the second fixing member abuts against the first inclined surface 234. When the second fixing member abuts against the first inclined surface 234, pressure is applied to the first inclined surface 234, so that the entire first extending part 232 moves in the direction close to the base 5, so that the abutting effect between the end side wall of the first joint 31 and the groove bottom of the first column-shaped groove 221 is better. Moreover, the arrangement of the first inclined surface 234 also avoids the situation that the first extending part 232 moves outward away from the first joint 31, and the connection effect is better.

[0057] Specifically, the side wall of the boss 231 close to the base 5 is provided with a plurality of third adjusting teeth 233 circumferentially around the first extending part 232. The inner side wall of the first rotating joint 3 is provided with a plurality of reinforcing columns circumferentially. The side wall of each reinforcing column close to the first extending part 232 is provided with a fourth adjusting tooth 311 matched with the third adjusting tooth 233. When the second fixing member fixes the first extending part 232 and the first joint 31 together, the fourth adjusting tooth 311 and the third adjusting tooth group 233 composed of the plurality of third adjusting teeth 233 abut against each other, which can play a role of resistance, so as to avoid the relative rotation of the first joint 31 relative to the connecting head 23 when the camera is used. Moreover, when it is necessary to adjust the camera angle of the shooting end circumferentially, it can be twisted according to the requirement to make it right or inclined to a certain angle. The second fixing member can be loosened, but the third adjusting tooth 233 still contacts with the fourth adjusting tooth 311, so that the first joint 31 rotates relative to the connecting head 23. By rotating a certain number of teeth, the camera angle of the shooting end can be accurately adjusted, and the purpose of rotating and stopping can also be achieved, which is convenient for adjustment.

[0058] Specifically, the end of the fourth joint 42 close to the base 5 is connected with the base 5, and the third fixing member is connected between the fourth joint 42 and the base 5. The third fixing member can be a bolt, and the fourth joint 42 and the base 5 can be detachably connected into an integral whole through the third fixing member, so that the fourth joint 42 can be detached from the base 5, which is convenient for maintenance and replacement.

[0059] Specifically, as shown in FIG. 8, the fourth joint 42 is provided with a fourth column-shaped groove 422, and the base 5 is provided with a fourth joint 43. The fourth joint 43 is provided with a fourth column-shaped groove 431, and the fourth column-shaped groove 422 of the fourth joint 42 is matched with the fourth column-shaped groove 431 of the fourth joint 43. Figures 8-9As shown, the second cylindrical groove 51 is provided on the side wall of the base 5 close to the connecting head 23, the bottom of the second cylindrical groove 51 is provided with a second protruding part 52, and the second protruding part 52 is in a cylindrical shape. A second annular mounting cavity is formed between the outer side wall of the second protruding part 52 and the second cylindrical groove 51. Correspondingly, the fourth connector 42 is also in a cylindrical shape. The end of the second protruding part 52 away from the second cylindrical groove 51 extends into the fourth connector 42. The end of the fourth connector 42 close to the base 5 is inserted into the second annular mounting cavity. The fourth connector 42 is in clearance fit with the second annular mounting cavity. Then, the third fixing member is used to make the third fixing member thread through the outer side wall of the fourth connector 42 and abut against the second protruding part 52 at the end, so that the second protruding part 52 and the fourth connector 42 are connected as a whole. When disassembling, the third fixing member is only needed to be loosened, and then the second protruding part 52 is pulled out of the fourth connector 42. The third fixing member can be a bolt.

[0060] Similarly, the second protruding part 52 is also provided with a second inclined surface 521. The large-diameter end of the second inclined surface 521 is farther away from the base 5 than the small-diameter end. When the third fixing member connects the second protruding part 52 and the fourth connector 42, the end of the third fixing member abuts against the second inclined surface 521, giving the second inclined surface 521 a pressure, so that the whole second protruding part 52 moves towards the mounting base, so that the end side wall of the fourth connector 42 and the bottom of the second cylindrical groove 51 are in better abutting effect. The second inclined surface 521 is also provided to avoid the second protruding part 52 from being separated from the fourth connector 42, so that the connection effect is better.

[0061] Similarly, a circle of fifth adjusting teeth is provided in the cavity bottom of the second annular mounting cavity, forming a fifth adjusting tooth group 53. Correspondingly, a plurality of reinforcing columns are provided on the inner side wall of the fourth connector 42 in a circumferential direction. Each reinforcing column is provided with a sixth adjusting tooth 46 close to the side wall of the base 5. Similarly, when the third fixing member fixes the second protruding part 52 and the fourth connector 42 together, the sixth adjusting tooth 46 and the fifth adjusting tooth group 53 formed by the plurality of fifth adjusting teeth abut against each other, which can play a role of resistance, avoiding the relative rotation of the fourth connector 42 relative to the base 5 when the camera is used. When the camera angle of the shooting end needs to be adjusted in a circumferential direction, the third fixing member is loosened, but the fifth adjusting tooth is still in contact with the sixth adjusting tooth 46, so that the fourth connector 42 rotates relative to the second protruding part 52. By rotating a certain number of teeth, the camera angle of the shooting end is accurately adjusted, and the purpose of stopping when rotating is also achieved, which is convenient for adjustment.

[0062] Specifically, the mounting shell 2 includes a front cover 21 and a rear shell 22. The end side wall of the rear shell 22 away from the base 5 is provided with a mounting port. The front cover 21 is connected to the mounting port by a bolt. The first cylindrical groove 221 is provided on the side wall of the rear shell 22 close to the base 5. Specifically, as shown inFigure 10 As shown, the camera body 1 includes a lens assembly 11, a lens bracket 12, and a motherboard assembly 13. The shooting end of the lens assembly 11 is located on the mounting hole provided in the front cover 21. The lens assembly 11 and the motherboard assembly 13 are both mounted on the lens bracket 12, and the three can form a whole. Moreover, the two ends of the lens bracket 12 are mounted on the inner side wall of the front cover 21 by bolts. During installation, the lens assembly 11 and the motherboard assembly 13 are first mounted on the lens bracket 12, then the lens bracket 12 is connected to the front cover 21, and finally the lens assembly 11, the lens bracket 12, and the motherboard assembly 13 are placed together into the rear cover 22, and the front cover 21 and the rear cover 22 are connected by bolts. The lens assembly 11, the lens bracket 12, and the motherboard assembly 13 can be connected as a whole without being separately installed in the rear cover 22, which facilitates the modular assembly and disassembly of the whole, and can improve the assembly efficiency of the entire camera to a certain extent.

[0063] like Figure 11 As shown, the lens bracket 12 includes a mounting plate 121 and two connecting plates 122. The two connecting plates 122 are respectively connected to the two sides of the mounting plate 121, forming a U-shaped structure. The lens assembly 11 and the motherboard assembly 13 are respectively mounted on the two side walls of the mounting plate 121, thus forming a single mounting unit. Both connecting plates 122 are bolted to the inner side wall of the front cover 21. Specifically, the motherboard assembly 13 includes electronic chips such as a CPU. A protruding plate 123 is provided on the corresponding mounting plate 121. The protruding direction of the protruding plate 123 faces the electronic chips such as the CPU inside the motherboard assembly 13. Thus, the protruding plate 123 is very close to the electronic chips such as the CPU inside the motherboard assembly 13. The heat dissipated by the electronic chips such as the CPU can be transferred to the entire lens bracket 12 through the protruding plate 123, thus acting as a heat sink. It is known that the lens bracket 12 is made of aluminum alloy. Furthermore, a guide post 222 is provided on the inner side wall of the rear housing 22, and a guide groove 124 is provided at the end of the connecting plate 122. When the entire lens assembly 11 is installed in the rear housing 22, the cooperation between the guide post 222 and the guide groove 124 ensures the convenience of installation and the accuracy of the position of the lens assembly 11.

[0064] Of course, the above lens assembly 11 and main plate assembly 13 are all composed of conventional components, and the specific components will not be described here.
