Description

Technical Field

[0001] The utility model relates to the technical field of industrial camera equipment, in particular to a side-view structure of a camera probe. Background Art

[0002] In the field of observation in narrow spaces, endoscopic camera probes are commonly used. Currently, there are mainly direct-view probes in the same direction as the axis of the pipeline and side-view probes at 90° to the axis of the pipeline. However, due to the strict restrictions on the size of the camera probe in narrow spaces, the existing small lens technology faces many difficulties. On the one hand, the size restriction makes it difficult for the lens to achieve a wide-angle field of view and close-focus effect. Due to the limited field of view angle, the direct-view camera probe can only rely on the residual light with poor imaging quality when observing the side walls of a narrow space. Even if a wide-angle lens is used, there are still problems with unclear and deformed peripheral images. On the other hand, when observing close-range objects, the 90° side-view camera probe cannot see the object clearly when it is less than the minimum imaging distance due to the requirements of the imaging object distance. In most cases, the observed object is not within the imaging range, resulting in unclear imaging or no imaging. At this time, the camera probe and the observed object need to be lifted and suspended in the air for a certain distance, making it difficult to control the operating distance and the observed imaging shaking and unstable.

[0003] At present, in order to solve the imaging distance problem of direct-view camera probes, side mirrors with reflectors are often screwed on the front end through threads. However, due to the size requirements of the narrow space, the area of ​​the reflective side mirror must be small, and the starting position of the threaded entry port is random during mass production, and different batches are also different. At the same time, the circular structure of the built-in lens module of the camera probe causes it to rotate freely in the sleeve, with random position and direction. This makes the reflective side mirror with a threaded structure screwed in, even if the imaging object distance is clear, but its stagnant fixed position does not match the position of the probe to collect the image, causing the image displayed on the screen to have a gap, and only a partial image can be seen, and full-screen display and image maximization display cannot be achieved. In short, the front end of the direct-view camera probe rotates through the thread, resulting in a clear imaging object distance but the field of view angle position and image acquisition direction cannot be accurately matched.

[0004] In summary, the side-view structure of the existing endoscopic camera probe for narrow spaces has many deficiencies in imaging effect, object distance adaptability and image display integrity, which need to be improved urgently. Utility Model Content

[0005] In view of this, the utility model proposes a side-view structure of a camera probe, aiming to overcome the problems of imaging mismatch and inability to adjust to a suitable position and fix due to the randomness of assembly and the randomness of the threaded connection entrance when the front end of the existing camera probe adopts a threaded connection reflector, and the problem that the display picture cannot be maximized while the image is clear due to the threaded connection reflective side mirror.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A side-view structure of a camera probe, comprising a camera probe and a side mirror module, the camera probe comprising a lens module and a mounting tube, the main body of the lens module being fixedly arranged in the mounting tube, the lens end of the lens module extending from the front end of the mounting tube, the side mirror module comprising a side mirror bracket, a reflective lens and a locking sleeve; the rear end outer wall of the mounting tube is provided with an external thread, the front end outer wall of the mounting tube is a halo structure; the side mirror bracket is a straight tube structure, the front part of the side mirror bracket is provided with a side mirror connected to the inner cavity of the side mirror bracket The side mirror bracket is provided with a front inclined surface of the lateral opening, and a reflective lens is installed. The mid-vertical line of the reflective lens is obliquely intersected with the central axis of the probe lens module. The rear end of the side mirror bracket is fixed with an elastic clamping part whose outer diameter decreases from front to back and whose inner diameter remains unchanged. The elastic clamping part is sleeved on the front end outer wall of the mounting tube. The rear end inner wall of the locking sleeve is provided with an internal thread, which is threadedly connected with the external thread. The front end inner wall of the locking sleeve is a conical structure with a reduced inner diameter from front to back, and the conical structure is clamped and matched with the elastic clamping part.

[0008] To better implement the above technical solution, optionally, the lateral opening is a V-shaped structure, and the lens end of the lens module extends into the lateral opening.

[0009] Optionally, the elastic clamping portion includes a plurality of strip structures with arc-shaped cross sections, the front ends of the strip structures are fixedly arranged at intervals on the circumference of the rear end surface of the side mirror bracket, and the rear ends of the strip structures are free ends.

[0010] Optionally, the angle formed by the perpendicular bisector of the reflective lens and the central axis of the probe lens module is 30°-70°.

[0011] Optionally, the reflective lens is glued to the front bevel of the lateral opening.

[0012] Optionally, the main body of the camera probe is glued into the mounting tube.

[0013] Beneficial effects of the utility model:

[0014] The side-view structure of a camera probe of the utility model abandons the traditional method of adjusting the angle and position of the reflective lens by rotating the thread at the same time, and instead adopts two independent actions of direct insertion and rotation to adjust the angle and distance of the side mirror relative to the camera probe. This adjustment method is not limited by the starting position of the threaded entry port, and can more flexibly and accurately achieve the preset angle and spacing between the reflective lens and the lens module, so that the image can be clear and the display screen can be maximized during imaging. In addition, the locking sleeve has a simple structure for fixing the side mirror bracket, which is not only easy to use, but also can be easily removed or replaced according to actual needs, and the cost is low. Compared with the existing threaded connection method, the adjustable range of the utility model is greatly increased, the adjustment accuracy is significantly improved, and the requirements for production accuracy and assembly process are significantly reduced.

[0022] like Figure 1 and Figure 2 As shown, the camera probe includes a lens module 10 and a mounting tube 20, the main body of the lens module 10 is fixed in the mounting tube 20, specifically, the main body of the lens module 10 is fixed in the mounting tube 20 by gluing, the lens end of the lens module 10 extends from the front end of the mounting tube 20, the rear end outer wall of the mounting tube 20 is provided with an external thread 21, and the front end outer wall of the mounting tube 20 is a halo structure 22;

[0023] like Figure 1 and Figure 3 As shown, the side mirror bracket 30 is a straight tubular structure, and a lateral opening 31 communicating with the inner cavity of the side mirror bracket 30 is provided at the front of the side mirror bracket 30, and a reflective lens 40 is installed on the front inclined surface of the lateral opening 31, and the mid-perpendicular line of the reflective lens 40 is obliquely intersected with the central axis of the probe lens module 10. Specifically, the reflective lens 40 is fixed to the front inclined surface of the lateral opening 31 by gluing, and an elastic clamping portion 32 whose outer diameter decreases from front to back and whose inner diameter remains unchanged is fixed at the rear end of the side mirror bracket 30, and the elastic clamping portion 32 is sleeved on the front end outer wall of the mounting tube 20;

[0024] like Figure 2 As shown, the rear inner wall of the locking sleeve 50 is provided with an internal thread 51, and the front inner wall is a conical structure 52 with a decreasing inner diameter from front to back. The internal thread 51 is threadedly connected with the external thread 21, and the conical structure 52 is clamped and matched with the elastic clamping part 32.

[0025] The side view structure of a camera probe of the embodiment of the utility model, when assembling the side mirror module, the specific steps are as follows: first, the locking sleeve 50 is sleeved on the mounting tube 20, so that the internal thread 51 of the inner wall at the rear end of the locking sleeve 50 is connected with the external thread 21 of the outer wall at the rear end of the mounting tube 20. Next, the side mirror bracket 30 is inserted into the front end outer wall of the mounting tube 20, and then according to the actual imaging requirements of the camera probe, the angle of the side mirror bracket 30 is rotated and its sleeve length on the mounting tube 20 is adjusted to make the reflective lens 40 and the lens module 10 reach the required angle and spacing. In this process, since two independent actions of direct insertion and rotation are used for adjustment, it is not affected by the starting position of the threaded entry port, and the ideal adjustment effect can be achieved more flexibly.

Compared with the existing threaded connection method, the adjustable range of the utility model is greatly increased, the adjustment accuracy is significantly improved, and the requirements for production accuracy and assembly process are significantly reduced.

The outer wall of the strip-shaped structure is a reduced diameter structure from front to back. The elastic clamping part 32 with such a structure cooperates with the locking sleeve 50, which can effectively enhance the stability and durability of the side view structure of the entire camera probe.
