[0021] The following will further elaborate on the preferred embodiments of the present utility model in conjunction with the drawings.

[0022] As Figures 1 to 4 shown, this embodiment provides a push rod structure for an industrial endoscope device, including: a bracket assembly 1, a steering structure 2, a steering arm assembly 3, and a connection assembly 4. The steering arm assembly 3 is connected to the bracket assembly 1 through the connection assembly 4, and the steering arm assembly 3 is coaxially rotatably connected to the bracket assembly 1. The steering structure 2 is fixedly connected to the steering arm assembly 3.

[0023] The bracket assembly 1 in this embodiment refers to the internal bracket of the industrial endoscope device, which is arranged in the housing 5 of the industrial endoscope device; the steering structure 2 refers to the steering push rod structure of the industrial endoscope device, and this steering push rod structure is used to achieve forward or backward pushing operations, and is preferably provided with anti-slip patterns; the steering arm assembly 3 is connected to the bracket assembly 1 through the connection assembly 4, and the steering arm assembly 3 is coaxially rotatably connected to the bracket assembly 1. The steering structure 2 is fixedly connected to the steering arm assembly 3. Thus, on the basis of the coaxial rotation of the steering arm assembly 3 and the bracket assembly 1, the steering structure 2 can smoothly achieve forward or backward pushing operations without lateral offset, effectively avoiding problems such as torsion or offset of the push rod structure and ensuring the consistency of the thrust. The structural design of this embodiment is reasonable, efficient, highly reliable, and has a long service life.

[0024] As Figure 2 and Figure 3 shown, the steering arm assembly 3 in this embodiment includes a first steering arm 301 and a second rotating arm 302, and the first steering arm 301 and the second rotating arm 302 are respectively arranged on both sides of the bracket assembly 1. By arranging the symmetric first steering arm 301 and second rotating arm 302 on both sides of the bracket assembly 1, the steering arm assembly 3 can smoothly achieve coaxial rotation with the bracket assembly 1, ensuring that the push rod of the steering structure 2 can always smoothly push forward or backward.

[0025] The outer edge shapes of the first steering arm 301 and the second rotating arm 302 in this embodiment correspond to the outer edge shapes of the corresponding positions of the bracket assembly 1. That is, if the outer edge of the corresponding position of the bracket assembly 1 is arc-shaped, then the outer edges of the first steering arm 301 and the second rotating arm 302 are also designed to be arc-shaped. Thus, during coaxial rotation, it can be ensured that the steering arm assembly 3 will not interfere with other surrounding structures and no additional avoidance design is required.

[0026] As Figure 2 and Figure 3 shown, the bracket assembly 1 in this embodiment is provided with a rotation connection hole 101, and the inner walls of the first steering arm 301 and the second rotating arm 302 are both provided with rotation connection shafts 303. The rotation connection shafts 303 are sleeved in the rotation connection hole 101, thus well realizing the coaxial rotation between the steering arm assembly 3 and the bracket assembly 1, and no problems such as dislocation will occur during the rotation process.

[0027] As Figure 2 and Figure 3As shown, the connection component 4 in this embodiment includes a first connection member 401 and a second connection member 402. The first connection member 401 and the second connection member 402 are respectively arranged on both sides of the bracket component 1 and pass through the rotation connection shaft 303 and the rotation connection hole 101. The first connection member 401 and the second connection member 402 include, but are not limited to, a plug pin, a machine screw, etc. The connection component 4 in this embodiment preferably further includes a protection member 403. The protection member 403 is arranged between the first connection member 401 and the steering arm assembly 3, or between the second connection member 402 and the steering arm assembly 3; the protection member 403 includes a spacer or a gasket. In practical applications, the setting of the protection member 403 can be determined according to the actual situation and requirements.

[0028] As Figure 2 and Figure 3 shown, on the outer walls of the first steering arm 301 and the second rotating arm 302 in this embodiment, connection seats 304 are provided. The connection component 4 is inserted into the connection seats 304. That is, the connection component 4 is recessed in the connection seats 304 on the outer sides of the first steering arm 301 and the second rotating arm 302, and thus can be well

[0029] As Figure 2 and Figure 3 shown, on the steering arm assembly 3 in this embodiment, an insertion-type mounting hole 305 is provided. The connecting arm 201 of the steering structure 2 is inserted into the mounting hole 305, so as to quickly realize the assembly and fixation between the steering structure 2 and the steering arm assembly 3, and is beneficial to the subsequent maintenance of the product. Preferably, the number of the connecting arms 201 in this embodiment is more than two, and the two or more connecting arms 201 are symmetrically arranged on the steering arm assembly 3, so as to further ensure the smooth performance during its working process. Of course, in practical applications, the number of the connecting arms 201 is not limited to two.

[0030] As Figures 2 to 4 shown, on the side wall of the bracket component 1 in this embodiment, a buckle structure 102 is provided. The buckle structure 102 is arranged in a dislocation manner with the rotation connection hole 101. Therefore, through the assembly structures such as the buckle structure 102, the bracket component 1 can be better buckled and assembled with the housing 5 of the industrial endoscope device, or structures such as the control main board in the housing 5, so as to improve the assembly efficiency of the product and ensure the stable reliability of the structure.
