Technical Field

[0001] The utility model belongs to the technical field of endoscopes, and in particular relates to a handheld telescopic endoscope device. Background Art

[0002] The endoscope is a multidisciplinary tool that can detect deep into narrow cavities in curved pipes, observe areas that cannot be directly observed by the human eye, observe the internal space structure and surface conditions in a sealed cavity, and achieve long-distance observation and operation. With the development of the endoscope, an integrated handheld industrial endoscope has emerged, which is small in size and easy to use.

[0003] However, in actual use, the lens of the existing handheld industrial endoscope is usually not protected. During use, the lens will often be scratched, affecting long-term use. In particular, during the continuous extension process, the lens will come into contact with the pipe wall and the probability of being scratched is high. Therefore, a handheld telescopic endoscope device is proposed. Summary of the invention

[0007] By adopting the above technical solution, the movement of the lens can be controlled by using the telescopic component, so that the wire can be moved toward the direction of the display body by operating the rotating ring. In this way, the protective endoscope component can protect the lens while allowing the lens to be extended for work.

[0008] Furthermore, a rotating groove matching the rotating ring is formed on the outer side of the fixing ring.

[0015] By adopting the above technical solution, the lens moves in the shell, so that when the lens is extended, the protective arc sheet can be opened for inspection, and when the lens is retracted, the protective arc sheet can be closed to protect the lens, and the use of spring 2 is conducive to the extension of the lens.

[0016] Furthermore, the left inner wall of the shell side is tilted outward, and the gap between the lens and the inner wall of the shell can accommodate the hinge of the protective arc sheet and the lens.

[0017] By adopting the above technical solution, the contact between the protective arc sheet and the lens can be facilitated by the inclined setting, and the gap can accommodate the hinge between the protective arc sheet and the lens.

The rotating ring 74 is sleeved on the outer side of the connecting arc piece 73, the fixed ring 75 is fixedly installed on the wire 5, and the rotating circle 76 is rotatably installed on the fixed ring 75. On the top, two connecting rods 77 are symmetrically arranged, one end of the connecting rod 77 is fixedly connected to the rotating circle 76, the other end of the connecting rod 77 is fixedly connected to the inner side of the rotating ring 74, one end of a spring 78 is fixedly connected to the outer side of the wire 5, and the other end of the spring 78 is fixedly connected to the connecting arc piece 73 located below. The movement of the lens 9 can be controlled by the telescopic component, so that the wire 5 can be moved toward the direction of the display body 2 by operating the rotating ring 74, so that the protective endoscope component can protect the lens 9 while allowing the lens 9 to extend for work.

[0030] The outer side of the fixed ring 75 is provided with a rotation groove matching the rotating circle 76. The rotation groove can prevent the fixed ring 75 from rotating when the rotating ring 74 rotates, thereby allowing the fixed ring 75 to move linearly.

The circular ring 71 can be used to protect the connection between the wire 5 and the electric plug 4.

[0032] The protective endoscope assembly includes a shell 81, a second spring 82, a third spring 83, a protective arc-shaped piece 84, and a accommodating chamber 85. The shell 81 is installed on the inner side of the end of the outer sleeve 6 away from the display body 2. The accommodating chamber 85 is arranged in the shell 81. Two second springs 82 are symmetrically arranged and installed between the lens 9 and the inner wall of the shell 81. There are multiple protective arc-shaped pieces 84 and they are hinged at the end of the lens 9 away from the second spring 82. There are multiple third springs 83.
