Description

Technical Field

[0001] The utility model relates to a snake tube structure of a variable-direction pipeline detection device, belonging to the field of industrial endoscopes. Background Art

[0002] The current industrial endoscope snake tube has a longer snake at the front end, which allows it to turn in a larger space; the longer snake without a guide block at the front end means it cannot turn in a small space; the catheter part does not have a guide block, and after passing through multiple turns, it cannot control the direction of propulsion well, such as up, down, left, or right.

[0003] Therefore, in order to facilitate turning in a small space, a new snake-bone tube structure was set up. At the same time, in order to make work smoother, some improvements were also made to the interior of the snake-bone tube. Utility Model Content

[0004] The purpose of the utility model is to provide a snake tube structure of a variable-direction pipeline detection device, which can effectively solve the above-mentioned problems.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] It includes a straight tube and a snake tube connected to the straight tube; a channel is arranged inside the straight tube and the snake tube, and an adjusting tube composed of a tightly wound spring is installed in the channel; and a spring tube is also arranged in the straight tube, and the number of the spring tubes is four and the circumference is evenly distributed around the adjusting tube.

[0007] Furthermore: one end of the straight tube is connected to a support seat, an entrance block is arranged in the support seat, an entrance channel connected to the channel is installed in the entrance block, a densely wound spring welding tube is arranged in the entrance channel; a densely wound spring fixing ring is arranged at the end of the snake bone tube.

[0008] Furthermore: the angle between the axis of the entrance channel and the horizontal plane is 20°.

[0009] Furthermore: a clamping assembly is also provided in the inlet block, and the clamping assembly includes a through hole penetrating inside and outside the inlet block, and a clamping bolt is provided in the through hole.

[0010] Further: the snake bone tube is wrapped with a protective cover.

[0011] Furthermore: the snake tube and the straight tube are connected via a connecting piece; the connecting piece includes a sleeve and a spring tube fixing ring.

[0012] The beneficial effects are:

[0013] When the industrial endoscope is in use, the operating wire is controlled by the hook handle. The operating wire is set in the spring tube, so the operating wire will deform and touch the inner wall of the straight tube. If a spring tube is set, the operating wire will touch the inner wall of the spring tube. Therefore, when the operating wire touches the inner wall of the spring tube, the spring tube will deform, which can make the operating wire smoother when adjusted.

[0014] The control operating line can adjust the rotation of the snake tube. When the snake tube bends, the transmission line of the industrial endoscope will be deformed, and the transmission line will touch the inner wall of the straight tube or the snake tube. The device is equipped with an adjustment tube composed of a densely wound spring, so the transmission line will touch the adjustment tube composed of a densely wound spring; the role of the adjustment tube is the same as that of the spring tube, which is to provide space for the transmission line to deform and reduce the wear of the transmission line.

[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 1-5This is an embodiment of the snake tube structure of the variable-direction pipeline detection device of the utility model.

[0025] It includes a straight tube 1 and a snake tube 2 connected to the straight tube 1; a channel 3 is provided in the straight tube 1 and the snake tube 2, and an adjusting tube 4 composed of a tightly wound spring is installed in the channel 3; and a spring tube 5 is also provided in the straight tube 1, and the number of the spring tubes 5 is four and the circumference is evenly distributed around the adjusting tube 4.

[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] Therefore, the device is equivalent to changing a longer snake-bone tube 2 into a shorter snake-bone tube 2 combined with a straight tube 1; the length remains unchanged, but the length that can control the turning is shortened. With this arrangement, the snake-bone tube 2 can be controlled to turn in a small space, and the straight tube 1 can also facilitate the control of extending the snake-bone tube 2 to the position that needs to be detected, which is very convenient to use.

[0029] At the same time, in order to better operate the inserted industrial endoscope, the device is provided with an adjustment tube 4 composed of a tightly wound spring in the straight tube 1 and the snake tube 2, the purpose of which is to provide a deformable ability for the operating wire inserted into the industrial endoscope;

[0030] When the industrial endoscope is in use, the operating wire is controlled by the hook handle, and the operating wire is set in the spring tube 5, so the operating wire will be deformed and touch the inner wall of the straight tube 1. If the spring tube 5 is set, the operating wire will touch the inner wall of the spring tube 5. Therefore, when the operating wire touches, the spring tube 5 will be deformed, which can make the adjustment of the operating wire smoother.

[0031] The control operation line can adjust the rotation of the snake tube 2. When the snake tube 2 rotates, the transmission line of the industrial endoscope will be deformed. At this time, the transmission line will also touch the inner wall of the straight tube 1 or the snake tube 2. The device is provided with an adjustment tube 4 composed of a densely wound spring, so the transmission line will touch the adjustment tube 4 composed of a densely wound spring; and the function of the adjustment tube 4 is the same as that of the spring tube 5 at this time, which is also to provide space for the transmission line to deform and reduce the wear of the transmission line.

[0032] One end of the straight tube 1 is connected to a support seat 6, an inlet block 7 is arranged in the support seat 6, an inlet passage connected to the channel 3 is installed in the inlet block 7, a densely wound spring welding tube 8 is arranged in the inlet passage; a densely wound spring fixing ring 9 is arranged at the end of the snake-bone tube 2.

[0033] When the device is in use, the industrial endoscope can be inserted into the entry channel along the entry block 7, and then enters the adjustment tube 4 composed of the tightly wound spring in the straight tube 1, so that a more stable operation can be performed.

[0034] The densely wound spring welding tube 8 and the densely wound spring fixing ring 9 of the device are used to fix the densely wound spring.

[0035] The angle between the axis of the entrance channel and the horizontal plane is 20°.

[0036] This angle makes it easy for workers to insert the industrial endoscope.

[0037] A clamping assembly 10 is further provided in the inlet block 7 . The clamping assembly 10 includes a through hole 11 penetrating inside and outside of the inlet block 7 . A clamping bolt 12 is provided in the through hole 11 .

[0038] When the device fixes the densely wound spring, the densely wound spring is welded to the densely wound spring welding tube 8, and then the clamping bolt 12 is tightened. The clamping bolt 12 can be used to press on the densely wound spring welding tube 8 to fix the densely wound spring welding tube 8.

[0039] The snake tube 2 is wrapped with a protective cover 13 .

[0040] The protective cover 13 is used to prevent the snake tube 2 from getting stuck.

[0041] The snake tube 2 is connected to the straight tube 1 via a connecting piece 14 ; the connecting piece 14 includes a sleeve 15 and a spring tube fixing ring 16 .

[0042] The function of the spring tube fixing ring 16 is to facilitate the fixing of the spring tube 5 , and the function of the sleeve 15 is to fix the snake tube 2 and the straight tube 1 together.

[0043] 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.
