A cavity is defined by the shell, the rear cover assembly is fixed to the rear end of the shell, and the camera shooting assembly is located in the cavity and comprises a camera shooting body and a rod-shaped lens connected with the camera shooting body. The elastic piece is located between the camera shooting assembly and the rear cover assembly, and after the rear cover assembly and the shell are assembled, the elastic piece provides elastic abutting force so that the front end of the lens can abut against the front end of the shell. The elastic piece applies forward abutting force to the camera shooting assembly, it is ensured that the lens abuts against the shell, and a window picture of the lens is prevented from being affected. In addition, due to the fact that the length of the shell is large, the length tolerance is large, the elastic piece can absorb the tolerance, and self-adaptive assembly is achieved.

When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0042] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a certain specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.

[0043] Refer Figures 1 to 2 , in some implementation modes, the camera assembly 300 of the implementation mode of the present application can be used for monitoring high-temperature kilns, mainly for monitoring the inside of high-temperature kilns, and the present application does not limit the application scenarios of the camera assembly 300.

[0044] In some embodiments, the camera assembly 300 includes a camera 100 and a power device 200. The power device 200 provides the power for the movement of the camera 100. When detection is required, the lens 32 of the camera 100 penetrates through the furnace wall 400 under the traction of the power device 200 and extends into the furnace for detection. After the detection is completed, the camera 100 retracts.

The first hole 211 allows the first shaft 351 to pass through for connection with the first knob 5, and the second hole 212 allows the second shaft 352 to pass through for connection with the second knob 6.

[0111] In some embodiments, a third hole 2221 corresponding to the first hole 211 is provided on the main body plate 222 for the first shaft 351 to pass through, which can prevent the first shaft 351 from skewing; a fourth hole 2222 corresponding to the second hole 212 is provided on the main body plate 222 for the second shaft 352 to pass through, which can prevent the first shaft 351 from skewing.

[0112] See Figure 3 and Figure 24 , the camera 100 includes a baffle 24 fixed to the rear cover 21 to block the first operating member and the second operating member, which can prevent accidental adjustment of the first operating member and the second operating member. When it is necessary to adjust the first operating member and the second operating member, the baffle 24 can be removed.

[0113] In some embodiments, the baffle 24 is fixed to the rear cover 21 by a limit screw 241 to facilitate the assembly and disassembly of the baffle 24. Optionally, the baffle 24 and the rear cover 21 can also be fixed by means such as snap connection or threaded connection.

[0114] See Figure 25 and Figure 26, the front end of the housing 1 is bent, and the front end of the lens 32 is also bent to meet the requirements of different scenarios.

[0115] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the scope of protection of this application.
