[0004] To achieve the above purpose, the utility model provides the following technical solution:

[0005] A centered peephole camera includes a support rod, a camera, a reserved groove, a telescopic rod, a spring, a rotating shaft, a support swing arm, a pulley, a connecting rod, and a fixed ear. The camera is installed inside the front end of the support rod. A reserved groove is opened inside the front end of the support rod. A telescopic rod is installed at the center of the rear end inside the reserved groove. A spring is installed at the rear end of the telescopic rod. A rotating shaft is installed at the front end of the telescopic rod, and support swing arms are installed at both the upper and lower ends of the rotating shaft. Pulleys are installed at the front ends of the upper and lower support swing arms. Connecting rods are installed on both the front and rear sides of the center of the support swing arm through rotating shafts. Fixed ears are integrally formed at the front of both the upper and lower ends of the support rod, and both the front and rear sides of the fixed ears are connected to the inner sides of the ends of the corresponding connecting rods through rotating shafts.

[0006] Preferably: A reserved hole is opened at the front end of the support rod, and the camera is installed in the reserved hole inside the front end of the support rod.

[0007] Preferably: The support rod, telescopic rod, rotating shaft, support swing arm, connecting rod, and fixed ear are all made of stainless steel.

[0008] The beneficial effect of the utility model is: The utility model is reasonably designed. By adapting the support swing arm to holes with different inner diameters and keeping the camera centered all the time, through the precise control of the camera, the technical requirements are reduced and the inspection efficiency is improved. Description of the Drawings

[0009] Figure 1 It is a cross-sectional structure schematic diagram of the centered peephole camera of the utility model;

[0010] Figure 2 It is a structure schematic diagram of the centered peephole camera of the utility model.

[0011] In the figure: 1. Support rod, 2. Camera, 3. Reserved groove, 4. Telescopic rod, 5. Spring, 6. Rotating shaft, 7. Support swing arm, 8. Pulley, 9. Connecting rod, 10. Fixed lug. Specific implementation mode

[0012] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0013] As Figure 1 - Figure 2 shown, a centered peephole camera includes a support rod 1, a camera 2, a reserved groove 3, a telescopic rod 4, a spring 5, a rotating shaft 6, a support swing arm 7, a pulley 8, a connecting rod 9, and a fixed lug 10. The camera 2 is installed inside the front end of the support rod 1. A reserved groove 3 is provided inside the front end of the support rod 1. A telescopic rod 4 is installed at the center of the rear end inside the reserved groove 3. A spring 5 is installed at the rear end of the telescopic rod 4. A rotating shaft 6 is installed at the front end of the telescopic rod 4, and support swing arms 7 are installed at both the upper and lower ends of the rotating shaft 6. Pulleys 8 are installed at the front ends of the upper and lower support swing arms 7. Connecting rods 9 are installed on both the front and rear sides of the center of the support swing arm 7 through rotating shafts. Fixed lugs 10 are integrally formed at the front sides of both the upper and lower ends of the support rod 1, and both the front and rear sides of the fixed lugs 10 are connected to the inner sides of the ends of the corresponding connecting rods 9 through rotating shafts. A reserved hole is provided at the front end of the support rod 1, and the camera 2 is installed in the reserved hole inside the front end of the support rod 1. The support rod 1, the telescopic rod 4, the rotating shaft 6, the support swing arm 7, the connecting rod 9, and the fixed lug 10 are all made of stainless steel.

[0014] The working principle of the present utility model: The camera 2 is sent into the hole through the support rod 1, and is sent into the hole by compressing the upper and lower support swing arms 7. The support swing arm 7 supports the telescopic rod 4 through the spring 5. The forward movement of the telescopic rod 4 drives the upper and lower support swing arms 7 to move outward through the rotating shaft 6, and supports the inner wall of the hole through the pulleys 8, so that the camera 2 is located at the center of the support swing arm 7 and the hole under the pulling of the connecting rod 9, which is convenient for observation and inspection.

[0015] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary, and equivalent changes within the equivalent scope are included in the scope of the present utility model.
