Description

Technical Field

[0001] This utility model relates to the field of industrial endoscopes, and in particular to an endoscope that can assist in supporting pipelines. Background Technology

[0002] Industrial endoscopes are a commonly used tool in industrial non-destructive testing. Flexible endoscopes are one type, and their insertion tube is the endoscope's tubing. This tube is typically fixedly connected to the operating handle. During use, when the operator turns the handle, a force is applied to the insertion tube. This results in frictional and torsional stress at the opening of the pipe being inspected and inside the pipe, causing frictional damage to the insertion tube and the lens at its tip. Furthermore, this stress can also lead to the insertion tube becoming entangled inside the pipe. Utility Model Content

[0003] To address the shortcomings of existing endoscopes, this invention provides an endoscope that can assist in supporting pipelines.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an endoscope that can assist in supporting the tubing, including an operating handle and a flexible tube insertion tube installed on the operating handle. The operating handle is rotatably mounted with a rotating component on the same side as the flexible tube insertion tube. The rotating component includes a rotating seat, a support block installed on the top of the rotating seat, and a rotating shaft extending downward from the bottom of the rotating seat and rotatably mounted on the operating handle. The support block is provided with a support block through hole that can match the insertion of the flexible tube. An arc-shaped protrusion extends circumferentially along the side wall of the rotating shaft. Multiple arc-shaped slots are provided at intervals on the outer edge of the arc-shaped protrusion, and stops extend at both ends of the arc-shaped protrusion. The operating handle is provided with a positioning bead that can match and be inserted into the arc-shaped slot. The arc-shaped protrusion rotates to both sides with the positioning bead as the center.

[0005] Preferably, the arc angle of the arc protrusion is less than 180 degrees, and the angle of rotation of the arc protrusion to both sides around the positioning bead is no greater than 90 degrees.

[0006] Preferably, the maximum angle at which the arc-shaped protrusion rotates clockwise or counterclockwise relative to the positioning bead is 85 degrees.

[0007] Preferably, the operating handle is provided with a mounting through hole that matches the mounting shaft, and the depth of the mounting through hole matches the distance between the bottom surface of the rotating seat and the arc-shaped protrusion.

[0008] Preferably, the support block is a triangular prism-shaped support block, which is connected to the rotating seat through one side. The support block has a through hole on its side, and the axis of the through hole is parallel to the side where the support block and the rotating shaft are connected.

[0009] Preferably, the support block through hole is provided with an elastically deformable annular rubber pad. Preferably, the flexible tube insertion tube is located at the lower front side of the operating handle, and the rotating assembly is installed at the upper front side of the operating handle.

[0010] Preferably, the top of the operating handle is provided with a handle behind the rotating assembly.

[0011] Preferably, the arc-shaped slot is a semi-circular slot.

[0012] Preferably, the tail end of the through hole in the support block has a rounded corner structure.

[0013] The beneficial effects of this utility model are as follows: This utility model utilizes the rotation of the support block relative to the operating handle. When the operator rotates the operating handle, the support block rotates to keep the hose insertion tube in its initial state. The force applied to the hose insertion tube when the operating handle is rotated is transmitted to the support block, and the support block will generate a corresponding reaction force, so that the hose insertion tube remains in its original state in the pipeline being tested, which can effectively avoid the tangling and wear of the pipeline.

Detailed Implementation

[0015] To more clearly illustrate the purpose, technical solution, and advantages of the embodiments of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. A clear and complete description will be provided. Obviously, the described embodiments are some, but not all, embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0016] Examples of embodiments of this utility model Figures 1 to 5As shown, an endoscope that assists in supporting tubing includes an operating handle 1 and a flexible tube insertion tube 2 mounted on the operating handle 1. Specifically, the operating handle 1 has a handle through-hole for installing the flexible tube insertion tube 2. The tail end of the flexible tube insertion tube 2 is installed inside the operating handle, and its head protrudes through the handle through-hole. The operating handle 1 is rotatably mounted with a rotating assembly on the same side as the flexible tube insertion tube 2. For example, if the flexible tube insertion tube 2 is located on the front side of the operating handle 1, the rotating assembly is also located on the front side of the operating handle 1. Preferably, the flexible tube insertion tube 2 is located at the lower part of the front side of the operating handle 1, and the rotating assembly is mounted on the upper part of the front side of the operating handle 1, facilitating the installation of the flexible tube insertion tube 2 onto the rotating assembly. The rotating assembly includes a rotating... The rotating seat 3, the support block 4 mounted on top of the rotating seat 3, and the limiting rotating shaft 5 extending downward from the bottom surface of the rotating seat 3 and mounted on the operating handle 1 are all present. The rotating seat 3 is located outside the operating handle 1, and the rotating shaft 5 is located in the middle of the bottom surface of the rotating seat 3, with its lower part inserted into the operating handle 1. The rotation of the rotating shaft 5 is limited within the operating handle 1, allowing the rotating seat 3 to drive the support block 4 to rotate relative to the operating handle 1. The support block 4 is provided with a support block through hole 40 that can accommodate a flexible tube insertion pipe 2. That is, the diameter of the flexible tube insertion pipe 2 is approximately the same as the diameter of the support block through hole 40. When needed, the flexible tube insertion pipe 2 is inserted into the support block through hole 40. At this time, the tail end of the support block through hole 40 has a rounded corner structure. This facilitates the insertion of the flexible support tube 2 into the through hole 40 of the support block. Simultaneously, after the flexible insertion tube 2 passes through the through hole 40 of the support block, it also prevents damage to the flexible insertion tube 2 caused by the edge of the through hole 40. An arc-shaped protrusion 50 extends circumferentially along the side wall of the rotating shaft 5. Multiple arc-shaped grooves 52 are spaced apart on the outer edge of the arc-shaped protrusion 50, and stoppers 51 extend from both ends of the arc-shaped protrusion 50. The arc-shaped protrusion 50 is located at the lower part of the rotating shaft 5. If a semi-circular arc-shaped groove 52 is selected, a positioning bead 6 that can be matched and inserted into the arc-shaped groove 52 is provided on the operating handle 1. The arc-shaped protrusion 50 rotates to both sides around the positioning bead 6, and the positioning bead 6 is fixedly positioned on the operating handle 1. The positioning bead 6 can be installed in the operating handle 1 first, opposite to the arc-shaped protrusion 50. Then, the rotating shaft 5 is installed with the center of the arc-shaped protrusion 50 aligned with the positioning bead 6. As the rotating shaft 5 rotates, the arc-shaped protrusion 50 rotates relative to the positioning bead 6 to both sides of the positioning bead 6. The angle of the rotating shaft 5 after rotation is limited by the engagement of the positioning bead 6 with the arc-shaped groove 52. When the rotating shaft 5 rotates to the point where the stop 51 and the positioning bead 6 come into contact, the rotating shaft 5 can no longer continue to rotate in that direction. The stop 51 at both ends of the arc-shaped protrusion 50 limits the rotation of the rotating shaft 5 to a certain arc angle. The semi-circular arc-shaped groove 52 facilitates the positioning bead 6 to be engaged and limited, while not affecting the rotation of the rotating shaft 5.At this time, the arc angle of the arc protrusion 50 is less than 180 degrees, and the angle of rotation of the arc protrusion 50 around the positioning bead 6 is no more than 90 degrees. That is to say, the positioning bead 6 is set corresponding to the center of the arc protrusion 50. In this way, the arc protrusion 50 rotates clockwise or counterclockwise relative to the positioning bead 6, and the maximum angle of clockwise or counterclockwise rotation is no more than 90 degrees. For example, the maximum angle of rotation of the arc protrusion 50 relative to the positioning bead 6 in clockwise or counterclockwise is 85 degrees. If the hose insertion tube 2 is set on the front side of the operating handle 1, and the axis of the support block through hole 40 is set to face forward in the initial state, the positioning bead 6 is fixedly set on the side wall inside the operating handle 1 that is parallel to the axis of the support block through hole 40 in the initial state. The arc protrusion 50 on the rotating shaft 5 is located on the side of the rotating shaft 5 corresponding to the positioning bead 6, and the hose insertion tube 2 is inserted from the rear end of the support block through hole 40.

[0017] Further improvements, such as Figure 2 and Figure 3 As shown, the operating handle 1 is provided with a mounting through hole 10 for mounting the rotating shaft 5. The depth of the mounting through hole 10 matches the distance between the bottom surface of the rotating seat 3 and the arc-shaped protrusion 50. The diameter of the mounting through hole 10 is equivalent to the diameter of the rotating shaft 5. The rotating seat 3 and the arc-shaped protrusion 50 are located at the upper and lower ends of the mounting through hole 10, respectively, which prevents the rotating shaft 5 from falling off the operating handle 1.

[0018] Further improvements, such as Figures 1 to 4 As shown, the support block 4 is a triangular prism-shaped support block 4. The support block 4 is connected to the rotating seat 3 through one side. The support block through hole 40 is set on the side of the support block 4, and the axis of the support block through hole 40 is parallel to the side of the support block 4 and the rotating shaft 5. That is, the triangular prism-shaped support block 4 is installed on the rotating seat 3 on its side, which provides better support and lift for the hose insertion tube 2 and does not affect its use.

[0019] Further improvements, such as Figure 4 As shown, an annular rubber pad 7 that can elastically deform is provided on the wall of the through hole 40 of the support block. The annular rubber pad 7 prevents damage to the hose insertion tube 2 when it passes through the through hole 40 of the support block.

[0020] Further improvements, such as Figure 1 and Figure 2 As shown, a handle 8 is provided on the top of the operating handle 1 behind the rotating component, which makes it convenient to pick up the operating handle 1.

[0021] Although the present invention has been described in detail above with general description and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
