[0002] Industrial endoscopes are mainly used in automobiles, aircraft engines, pipelines, mechanical parts, etc. They can achieve non-destructive testing without disassembling or destroying the assembly and stopping the equipment. They are widely used in various departments of modern core industries such as aviation, automobiles, ships, electrical, chemical, electricity, gas, atomic energy, civil engineering, etc.

[0003] Currently, the long snake body of industrial endoscopes means that they cannot turn in a small space; there are no guide blocks on the catheter part, and after passing through multiple turns, the direction of propulsion cannot be well controlled, such as up, down, left, and right.

[0004] Therefore, a new guide tube needs to be designed to help the snake bone turn. Utility Model Content

[0008] Further: a threaded hole is arranged on the semicircular body, and a bolt is arranged in the threaded hole.

[0009] Furthermore: the channel in the inlet block is a circular channel, and the angle between the axis of the circular channel and the horizontal plane is 20°.

[0010] Furthermore: the support seat and the catheter are connected via a connecting assembly; the connecting assembly includes a sleeve, an internal thread is provided in the sleeve, and a clamping ring is also provided in the sleeve, an inner tube with an external thread is provided on one side of the support seat, and the sleeve and the inner tube are connected via threads; an abutment ring is also provided between the catheter and the support seat, and the abutment ring abuts against the clamping ring.

[0011] Further: the catheter and the snake tube are connected via a snake connecting tube, the snake connecting tube is a straight tube, and the catheter and the snake tube are welded together.

[0012] Further: the hook handle and the support seat bracket are fixed through an inlet connector.

[0013] The beneficial effects are:

[0014] The device is used to pass the probe and insertion tube of the industrial endoscope through the device together. With the help of the turning function of the snake-bone hook with a larger outer diameter at the front end of the device, the insertion tube of the industrial endoscope is deformed to achieve a turn, thereby passing the probe into a bifurcation position that cannot be penetrated by using an industrial endoscope alone.

[0015] By connecting the channel in the support seat and the hollow conduit, a channel for the detection head to pass through can be formed, and then the snake tube at the end of the conduit can realize the universal rotation of the detection head; this solves the problem that the snake tube is too long and inconvenient to turn in a small space.

[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0024] See also Figure 1-4This is an embodiment of the guide pipe structure of the variable-direction pipeline detection device of the utility model.

[0025] It includes a hook handle 1, which is connected to a support base 2, one end of the support base 2 is connected to a catheter 3, and one end of the catheter 3 is provided with a snake tube 4; an entrance block 5 is provided on the support base 2, and a channel 6 is provided in the entrance block 5, and the channel 6 is connected to the inside of the catheter 3; a guide block 7 is also provided outside the catheter 3; the guide block 7 is cylindrical as a whole, and is composed of two semicircular bodies 71.

[0026] The industrial endoscope is a multidisciplinary tool that can be used to explore deep into curved pipes, observe areas that cannot be viewed directly, observe the internal space structure and status in a sealed cavity, and achieve long-distance observation and operation.

[0027] Endoscopes that use fiber beams to transmit images and light or CCD to transmit images are called soft endoscopes. Because of its good softness and convenient operation performance, the characteristics of soft endoscopes are: easy access and can reach places that hard endoscopes cannot reach. With the addition of a head bending mechanism, blind spots can be eliminated. Industrial endoscopes are usually equipped with snake tubes to work together.

[0028] The device is used to pass the probe and insertion tube of the industrial endoscope through the device together. With the help of the turning function of the snake-bone hook with a larger outer diameter at the front end of the device, the insertion tube of the industrial endoscope is deformed to achieve a turn, thereby passing the probe into a bifurcation position that cannot be penetrated by using an industrial endoscope alone.

[0029] By connecting the channel 6 in the support base 2 and the hollow conduit 3, a channel for the detection head to pass through can be formed, and then the snake tube 4 at the end of the conduit 3 can realize the universal rotation of the detection head; thus, the problem that the snake tube 4 is too long and inconvenient to turn in a small space is solved;

[0030] Therefore, the device is equivalent to changing a longer snake tube 4 into a shorter snake tube 4 combined with a straight tube catheter 3; the length remains unchanged, but the length that can control the turning is shortened. With this arrangement, the snake tube 4 can be controlled to turn in a small space, and the straight tube catheter 3 can also facilitate the control of extending the snake tube 4 to the position that needs to be detected, which is very convenient to use.

[0031] At the same time, the device is also provided with a guide block 7, the function of which is to use the upper and lower end surfaces of the guide block 7 to be stuck in the pipeline when extending into the pipeline, so as to make the device more stable.

[0032] The purpose of setting the support base 2 in the device is to set the entry block 5, and the entry block 5 is mainly set to facilitate the staff to insert the endoscope probe into the catheter 3.

[0033] The semicircular body 71 is provided with a threaded hole 72 , and a bolt is provided in the threaded hole 72 .

[0034] The guide block 7 in the device is adjustable and can be adapted and adjusted according to the diameter of the pipe to be detected. The specific adjustment method is to tighten the bolt to control the distance between the two semicircular bodies 71.

[0035] The channel 6 in the inlet block 5 is a circular channel, and the angle between the axis of the circular channel and the horizontal plane is 20°.

[0036] Since the lines of industrial endoscopes are all circular, channel 6 is set as a circular channel to facilitate the insertion of the endoscope; and the setting of the angle is also considered to facilitate insertion by the staff, so a 20° angle is set.

[0037] The support seat 2 and the catheter 3 are connected by a connecting assembly 8; the connecting assembly 8 includes a sleeve 81, an internal thread is provided in the sleeve 81, and a retaining ring 82 is also provided in the sleeve 81. An inner tube 83 with an external thread is provided on one side of the support seat 2, and the sleeve 81 and the inner tube 83 are connected by threads; an abutment ring 84 is also provided between the catheter 3 and the support seat 2, and the abutment ring 84 abuts against the retaining ring 82.

[0038] The device tightly connects the support base 2 and the conduit 3 through the sleeve 81 , so that the hollow conduit 3 can be connected to the channel 6 .

[0039] The catheter 3 and the snake tube 4 are connected by a snake connecting tube 9, which is a straight tube and welds the catheter 3 and the snake tube 4 together. The hook handle 1 is a prior art, and its purpose is to facilitate the control of the industrial endoscope, while the snake tube 4 is to facilitate the universal adjustment of the industrial endoscope.

[0040] The hook handle 1 and the support base 2 bracket are fixed by an inlet connector 10 .

[0041] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
