Description

Technical Field

[0001] This utility model relates to the field of surveillance camera technology, and specifically to a surveillance camera fixing structure. Background Technology

[0002] Card-type cameras are typically designed to be small and compact, resembling the shape of a card. They are easy to install in various locations and are relatively inconspicuous after installation, allowing them to blend well into environments where aesthetics are important. Card-type cameras can be quickly installed using simple methods such as pasting, adsorption, or clips, often without the need for complex wiring or drilling, making installation easy for ordinary people.

[0040] In view of the shortcomings of the prior art, this embodiment provides a fixing structure for a surveillance camera, which can be referred to as follows:

[0041] As attached Figure 1 Appendix Figure 2 and attached Figure 5 As shown, a surveillance camera fixing structure includes a base 1, a metal rod 2, a housing 3, and a retaining ring 4. The metal rod 2 and the housing 3 are disposed on the top of the base 1. The housing 3 has an internal cavity for housing electronic components such as a control board and a camera. The bottom of the housing 3 has a through hole to connect the internal cavity to the outside. The metal rod 2 is cylindrical, with its top passing through the through hole and located inside the internal cavity of the housing 3. The metal rod 2 abuts against the bottom of the housing 3. The housing 3 also has a retaining ring 4 inside, which connects to the metal rod 2 located inside the housing 3, thereby connecting the retaining ring 4, the metal rod 2, and the housing 3.

[0042] Specifically, the retaining ring 4 can be placed inside the housing 3 first, and then the metal rod 2 on the base 1 can be passed through the through hole. The metal rod 2 located outside the housing 3 abuts against the outer surface of the housing 3, while the metal rod 2 located inside the housing 3 is connected to the retaining ring 4. The metal rod 2 and the retaining ring 4 are respectively engaged on the inner and outer sides of the housing 3, so that the metal rod 2, the retaining ring 4 and the housing 3 are connected. By placing the top of the metal rod 2 inside the housing 3 and connecting it with the retaining ring 4, the retaining ring 4 can be tightly abutted against the inner wall of the housing 3, thus realizing the connection between the metal rod 2 and the housing 3. Compared with the prior art, the arc surface of the retaining ring 4 abuts against the inner wall of the housing 3, which can increase the contact area between the connecting structure and the housing 3. Furthermore, through the action of the metal rod 2 and the housing 3, the retaining ring 4 can be abutted against the inner wall of the housing 3, thereby making the connection between the housing 3 and the base 1 more stable.

[0043] In this embodiment, as shown in the appendix Figure 3 and attached Figure 4 As shown, a mating groove is provided at the bottom of the through hole, and a flat groove is provided on the side wall of the hardware rod 2, and a step is formed at the bottom of the flat groove, which abuts against the mating groove.

[0044] In this embodiment, as shown in the appendix Figure 2 As shown, two symmetrical arc-shaped grooves are provided on the inner wall of the housing 3. The two arc-shaped grooves are arranged at intervals and are connected to the inner wall of the housing 3 to form a limiting groove 31. The retaining ring 4 is located in the limiting groove 31, and the inner wall of the limiting groove 31 abuts against the inner wall of the retaining ring 4 to restrict the movement of the retaining ring 4.

[0045] Specifically, the two arc-shaped groove plates, together with the housing 3, form a limiting groove 31, with openings on one side and top of the limiting groove 31. The openings on one side and top of the limiting groove 31 facilitate the insertion of the retaining ring 4.

[0046] One embodiment of this application is shown in the appendix. Figure 6 As shown, the retaining ring 4 includes a fixing part 41, an abutting part 42, multiple abutting blocks 43, and an extension plate 44. The abutting part 42 is located at the bottom of the fixing part 41. When the retaining ring 4 is inserted, the fixing part 41 is located at the opening at the top of the limiting groove 31, while the abutting part 42 is located at the opening on one side of the limiting groove 31 and is inserted into the limiting groove 31 through the opening on one side of the limiting groove 31. The bottom wall of the abutting part 42 is an arc surface, and multiple abutting blocks 43 are spaced apart on the arc surface. The abutting blocks 43 are elongated, and a groove is formed between two adjacent abutting blocks 43 to increase the force between them and the side wall of the housing 3. An extension plate 44 is also provided on the arc surface. The length of the extension plate 44 is in the same direction as the front and back of the monitoring camera. The extension plate 44 increases the contact area of ​​the retaining ring 4 in the front and back direction of the monitoring camera.

[0047] By setting multiple abutment blocks 43 on the bottom wall of the abutment part 42, the friction between the retaining ring 4 and the inner wall of the housing 3 can be effectively increased, thereby improving the stability between the retaining ring 4 and the housing 3. Furthermore, by setting multiple abutment blocks 43 and extension plate 44, the contact area between the retaining ring 4 and the housing 3 is increased, thereby further improving the stability between the hardware rod 2 and the housing 3.

[0048] In this embodiment, as shown in the appendix Figure 6 As shown, the height of the abutment block 43 and the extension plate 44 gradually increases from the rear end of the monitoring camera to the front end. That is, the bottom surface of the abutment block 43 and the extension plate 44 is inclined. When the retaining ring 4 is inserted into the limiting groove 31, under the action of the abutment block 43 and the extension plate 44, the top wall of the abutment part 42 can abut against the inner wall of the limiting groove 31, thereby preventing the retaining ring 4 from dislodging from the limiting groove 31.

[0049] In this embodiment, as shown in the appendix Figure 5 and attached Figure 6 As shown, a through hole 45 is provided at the center of the fixing part 41 and the abutting part 42. The through hole 45 passes through both the fixing part 41 and the abutting part 42. The top of the hardware rod 2 is located inside the through hole 45. A first connecting hole 46 is provided on one side of the fixing part 41, and a second connecting hole 21 is provided on one side of the top of the hardware rod 2. The first connecting hole 46 and the second connecting hole 21 are connected by a first bolt.

[0050] The first connecting hole 46 corresponds to the second connecting hole 21 and is perpendicular to the through hole 45. When the hardware rod 2 is inserted into the through hole 45, the first bolt can be inserted into the first connecting hole 46 and the second connecting hole 21 to connect the retaining ring 4 to the hardware. Specifically, the second connecting hole 21 can be a threaded hole. The first bolt is inserted into the first connecting hole 46 and the threads engage with the second connecting hole 21, which can effectively prevent the first bolt from coming out of the first connecting hole 46 and the second connecting hole 21.

[0051] Furthermore, a first mounting post 32 is provided on the inner wall of the housing 3, the side wall of the fixing part 41 abuts against the first mounting post 32, and the first bolt passes through the first connecting hole 46 and the second connecting hole 21 and is connected to the first mounting post 32, thereby connecting the housing 3, the hardware rod 2 and the retaining ring 4.

[0052] The first connecting hole 46 and the second connecting hole 21 can be through holes, while the first mounting post 32 has a threaded hole inside. The threaded hole of the first mounting post 32 corresponds to the first connecting hole 46 and the second connecting hole 21, so that the first bolt can pass through the first connecting hole 46 and the second connecting hole 21 and engage with the threaded hole in the first mounting post 32. As the first bolt rotates with the threaded hole in the first mounting post 32, the large end of the first bolt will also abut against the fixing part 41, so that the retaining ring 4, the hardware rod 2 and the housing 3 are fastened together.

[0053] In this embodiment, a first mating surface 47 is provided on the inner wall of the through hole 45, and a second mating surface 22 is provided on one side of the top of the hardware rod 2. The first mating surface 47 and the second mating surface 22 are mated together. Both the first mating surface 47 and the second mating surface 22 are planar. The first connecting hole 46 and the second connecting hole 21 are aligned through the first mating surface 47 and the second mating surface 22 to facilitate the connection between the retaining ring 4 and the hardware rod 2.

[0054] The second mating surface 22 is formed by the flat groove on the hardware rod 2, that is, the second mating surface 22 is the side wall of the flat groove, and the flat groove also abuts against the mating groove at the bottom of the through hole.

[0055] In this embodiment, as shown in the appendix Figure 5 As shown, a support rod 11 is provided on the top of the base 1, and a guide groove 12 is provided on the top of the support rod 11. A ball groove 13 is provided inside the guide groove 12, and a spherical connecting block 23 is provided at the bottom of the hardware rod 2. The spherical connecting block 23 is connected to the ball groove 13, and the bottom of the hardware rod 2 is located inside the guide groove 12. Through the action of the spherical connecting block 23 and the ball groove 13, the hardware rod 2 and the support rod 11 can rotate. However, under the action of the guide groove 12, the hardware rod 2 can only rotate relative to the support rod 11 along the slotting direction of the guide groove 12.

[0056] Furthermore, the front end of the guide groove 12 is open, while the rear end of the guide groove 12 is closed. In the initial state, the hardware rod 2 and the support rod 11 are in a vertically parallel state, and the outer surface of the hardware rod 2 abuts against the rear end of the guide groove 12. That is, the hardware rod 2 can only rotate forward relative to the support rod 11, thereby adjusting the angle between the housing 3 and the support rod 11 of the base 1.

[0057] One embodiment of this application is shown in the appendix. Figure 3 As shown, the housing 3 includes a bottom shell 33 and a top shell 34. The bottom shell 33 has an opening on one side to facilitate the installation of internal components and retaining rings 4, etc. The bottom shell 33 is connected to the retaining rings 4 and the hardware rod 2. The top shell 34 is provided at the opening of the bottom shell 33 and is used to close the opening. The top shell 34 has multiple holes to facilitate the exposure of components such as cameras or infrared sensors.

[0058] In this embodiment, as shown in the appendix Figure 2 and attached Figure 7As shown, the inner side of the bottom shell 33 is provided with multiple buckles 35, and the side of the front shell 34 near the bottom shell 33 is provided with a first support rib 36. The first support rib 36 is provided with multiple slots 37, and the slots 37 correspond one-to-one with the buckles 35 and cooperate with each other. Specifically, the buckles 35 are provided with a chamfer on the side near the opening of the bottom shell 33. When the front shell 34 and the bottom shell 33 are installed, the front shell 34 can be abutted against the opening of the bottom shell 33, and the first support rib 36 is engaged with the inner wall of the bottom shell 33. Guided by the first support rib 36, the first support rib 36 of the front shell 34 can slide into the interior of the bottom shell 33 until the slots 37 contact the buckles 35. Under the action of the chamfer of the buckles 35, the slots 37 can undergo slight deformation. Then, as the front shell 34 slides, the slots 37 and the buckles 35 engage, thereby fixing the front shell 34 and the bottom shell 33.

[0059] Furthermore, after the face shell 34 is engaged with the bottom shell 33, the first support rib 36 of the face shell 34 abuts against the extension plate 44 of the retaining ring 4, thereby further limiting the movement of the retaining ring 4.

[0060] In this embodiment, a plurality of second support ribs 38 are provided on the inner wall of the bottom shell 33. The second support ribs 38 are L-shaped and are respectively connected to two adjacent side walls of the bottom shell 33 to improve the strength of the bottom shell 33.

[0061] In this embodiment, a charging port is provided on the rear side of the bottom shell 33. The charging port corresponds to the connection port on the circuit board, that is, the charging component on the circuit board is located inside the charging port, so as to facilitate the connection of the charging component with an external charging device to provide power to the circuit board and the components inside the shell 3.

[0062] Furthermore, a memory card slot is provided on the rear side of the bottom shell 33 to facilitate the insertion of a memory card.
