In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0041] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0042] As Figures 1-10 shown, an embodiment of the present utility model provides a conch-shaped camera, which includes a camera body 1, a rear housing cover 2, a base 3, and a fixing member 4. The camera body 1 is used for taking pictures. The base 3 and the rear housing cover 2 can be connected together through the fixing member 4. The base 3 is provided with a threaded hole. After the camera body 1 is installed, the front imaging part of the camera body 1 is located outside the rear housing cover 2, and the rear part is located inside the rear housing cover 2. Moreover, after the camera body 1, the rear housing cover 2, and the base 3 are connected, they form a conch shape, having advantages such as beauty, concealment, and integration.

[0043] Specifically, as Figures 6-7As shown, a plurality of connecting protrusions 5 are circumferentially provided on the inner side wall of the base 3. The connecting protrusions 5 are integrally formed with the base 3 and can be mold - opened parts. One end of the connecting protrusion 5 far from its connection point is the free end, and an elastic sleeve 6 is sleeved at the free end. The elastic sleeve 6 has elasticity and can be extruded under the action of an external force. When the base 3 is connected to the rear housing cover 2, one end of the base 3 close to the rear housing cover 2 is located inside the rear housing cover 2, and the free end of the connecting protrusion 5 is located inside the rear cover housing. Correspondingly, the elastic sleeve 6 is also located inside the rear cover housing, and a plurality of elastic sleeves 6 form a limiting area circumferentially. When the rear part of the camera body 1 is installed inside the rear housing cover 2, its rear end is located inside the limiting area. The base 3 and the rear housing cover 2 can be connected together by a fixing member 4. The fixing member 4 can be a screw. When the fixing member 4 does not fasten the base 3 and the rear housing cover 2 together, the outer side wall of the rear end of the camera body 1 is in contact with a plurality of elastic sleeves 6, but the rear end of the camera body 1 is not completely limited and fastened. The rear end of the camera body 1 can rotate inside the limiting area, so that the shooting angle of the camera body 1 can be adjusted. After adjusting the angle, the fixing member 4 passes through the outer side wall of the rear housing cover 2 and abuts against the outer side wall of the base 3. At this time, the fixing member 4 applies pressure to the outer side wall of the base 3, so that the base 3 is slightly deformed, and part of the connecting protrusion 5 moves radially inward. Correspondingly, the elastic sleeve 6 also moves radially inward, so that the limiting area formed by a plurality of elastic sleeves 6 shrinks, the elastic sleeve 6 is compressed, and a plurality of elastic sleeves 6 are tightly abutted against the outer side wall of the rear end of the camera body 1, thereby fixing the camera body 1 inside the rear housing cover 2, and completing the installation and fixation of the entire conch - shaped camera, with stable use. If the shooting angle of the camera body 1 needs to be adjusted again, only loosen the fixing member 4 so that the fixing member 4 no longer abuts against the outer side wall of the base 3, and then rotate the camera body 1. After adjustment, tighten the fixing member 4 again so that it abuts tightly against the outer side wall of the base 3, thereby completing the re - adjustment of the shooting angle of the camera body 1, which is convenient to use.

[0044] Specifically, a communication hole 22 is provided on the lower side wall of the rear housing cover 2. The communication hole 22 is inclined upward. The rear part of the camera body 1 is located inside the rear housing cover 2, the rear end is located inside the limiting area, and the front shooting part passes through the communication hole 22 and is located outside the rear housing cover 2. It can be known that the outer diameter of the rear end of the camera body 1 is greater than the maximum outer diameter of the communication hole 22, so that the camera body 1 will not fall through the communication hole 22 from inside the outer housing.

[0045] In summary, by setting the cooperation of a plurality of connecting protrusions 5 and elastic sleeves 6 to form a limiting area, after the rear end of the camera body 1 is installed in the rear housing cover 2, it is located within the limiting area. When the rear housing cover 2 and the base 3 are not locked, the camera body 1 can adjust the angle. After adjusting the angle, the rear housing cover 2 and the base 3 are locked by the fixing member 4, and the rear end of the camera body 1 is abutted and fixed by a plurality of elastic sleeves 6, without damaging the outer shell of the camera body 1. Compared with the prior art where the rear end of the camera body 1 is not fixed, the shooting angle of the camera body 1 will not be easily changed after adjustment, and the use is more stable; moreover, when the angle of the camera body 1 needs to be adjusted again, only the fixing member 4 needs to be loosened, and then the camera body 1 can be rotated, which is convenient to adjust.

[0046] Specifically, as Figure 6 shown, one end of the base 3 close to the rear housing cover 2 is provided with an extending portion 31. When the base 3 is connected to the rear housing cover 2, the extending portion 31 extends into the rear housing cover 2. The outer side wall of the extending portion 31 is provided with an inclined surface 32, and the inclined surface 32 is inclined towards the inner side wall of the rear housing cover 2. The fixing member 4 passes through the side wall of the rear housing cover 2 and abuts against the inclined surface 32, so that the rear housing cover 2 and the base 3 are connected. At this time, the fixing member 4 will apply a downward inclined force to the inclined surface 32, and the inclined surface 32 gives an upward inclined reaction force to the fixing member 4, making the pre-tightening effect of the fixing member 4 on the extending portion 31 more stable than the planar abutment, and making the connection between the base 3 and the rear housing cover 2 more stable.

[0047] Specifically, in this embodiment, the extending portion 31 is a ring structure. One end of the extending portion 31 away from the base 3 is provided with a clamping portion 33, and the clamping portion 33 can also be annular correspondingly. A clamping groove 21 matching with the clamping portion 33 is provided on the inner side wall of the rear housing cover 2. The clamping groove 21 is located on the opposite side wall of the installation point of the fixing member 4 on the rear housing cover 2. In this embodiment, the connection point of the fixing member 4 is located on the front side wall of the rear housing cover 2, so the clamping groove 21 is located on the rear inner side wall of the rear housing cover 2. Thus, when the extending portion 31 of the base 3 is located in the rear housing cover 2, the clamping portion 33 cooperates with the clamping groove 21. Thus, when the fixing member 4 fastens the rear housing cover 2 and the base 3, during the micro-deformation process of the base 3, it is avoided that the side wall of the extending portion 31 away from the fixing member 4 falls off from the rear housing cover 2, ensuring that the extending portion 31 of the base 3 is stably located in the rear housing cover 2. Specifically, two convex platforms are provided on the inner side wall of the rear housing cover 2, and the two convex platforms are arranged at intervals to form the clamping groove 21.

[0048] Specifically, as Figure 4As shown, the side wall of the elastic sleeve 6 close to the camera body 1 is set as a fastening wall 61. The shape of the outer side wall of the fastening wall 61 is adapted to the shape of the outer side wall of the rear end of the camera body 1, so as to facilitate the contact between the elastic sleeve 6 and the outer side wall of the rear end of the camera body 1. Moreover, a limiting protrusion 62 is provided in the middle of the outer side wall of the fastening wall 61, so that the middle of the outer side wall of the fastening wall 61 can also stably contact the outer side wall of the rear end of the camera body 1 through the limiting protrusion 62, so that the entire fastening wall 61 of the elastic sleeve 6 can stably contact the outer side wall of the rear end of the camera body 1. After the camera body 1 adjusts the angle, the rear end of the camera body 1 can be stably fixed in the limiting area by a plurality of elastic sleeves 6, and the shooting angle of the camera body 1 will not easily change due to external factors.

[0049] Specifically, as Figure 5 shown, a thickening protrusion 63 is provided on the inner side wall of the fastening wall 61, which can increase the thickness and service strength of the fastening wall 61. Moreover, a connecting groove 51 is provided at the free end of the connecting protrusion 5. After the elastic sleeve 6 is sleeved on the free end of the connecting protrusion 5, the thickening protrusion 63 is located in the connecting groove 51 to play a connecting role and can further prevent the elastic sleeve 6 from falling off the free end of the connecting protrusion 5. Specifically, the elastic sleeve 6 is a rubber sleeve.

[0050] Specifically, in this embodiment, as Figure 1 shown, the camera body 1 includes a front shell 11, a light shielding plate 12, a lamp board 13, an SD card board 14, a lens 15, a main board 16, a heat dissipation bracket 17 and a rear shell 18.
