Description

Technical Field

[0001] This utility model belongs to the field of pipeline endoscope equipment, and specifically relates to a detachable pipeline endoscope winding reel. Background Technology

[0002] A pipe endoscope is a device used to inspect the internal condition of pipes. It typically consists of a crawler, cable, camera, and other accessories. The crawler carries the camera deep into the pipe to capture real-time images or videos of the pipe interior, helping to detect problems such as blockages, corrosion, cracks, or other structural damage.

[0003] The cable of a pipe endoscope is usually wound on a reel, which is movably mounted on the main frame. During use, the cable is fed out and retracted by rotating the reel. However, most existing reels are not easy to disassemble, and the few that are easy to disassemble lack braking and metering functions, making it inconvenient to control the cable feed or retraction, and also inconvenient to measure the cable length. Utility Model Content

[0004] To address the aforementioned problems, the primary objective of this invention is to provide a detachable endoscope winding reel that facilitates disassembly and assembly, thereby enabling convenient replacement and maintenance of various components.

[0005] Another objective of this invention is to provide a detachable pipe endoscope winding reel with braking and meter counting functions, enabling multi-functional use.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model provides a detachable endoscope winding reel, comprising:

[0008] Winding rack for taking up cables;

[0009] Main frame used for mounting winding frames;

[0010] Braking structure used to stop the winding frame from rotating;

[0011] A multi-functional component with a rotating meter-counting function;

[0012] The multifunctional component includes a housing, an aviation connector module, an encoding module, bearings, and fasteners. The encoding module includes a PCB adapter board, an encoder, an encoder base, a hollow slip ring, and a D-shaped shaft cover. The aviation connector module is fixed to the main frame, and the aviation connector module and the housing are rotatably connected via bearings. The winding frame is detachably mounted on the housing and locked in place by fasteners. The encoder is mounted on the encoder base, and the encoder's output shaft is fixed to the housing via the D-shaped shaft cover. The hollow slip ring is mounted on the encoder's output shaft, and the encoder, aviation connector module, and hollow slip ring are all electrically connected to the PCB adapter board. The housing also has an interface for connecting cables to the aviation connector module.

[0013] The above structure facilitates the assembly and disassembly of the winding frame and multi-functional components, thereby enabling easy replacement and maintenance of various parts. Simultaneously, the encoding module has a metering function, capable of measuring the cable's outgoing length, and the braking structure controls the rotation of the winding frame, thereby controlling the cable's inlet and outlet, thus achieving a multi-functional effect.

[0014] In this application, one end of the aviation connector module is connected to the endoscope host. The cable is wound on the winding frame, and one end of the cable passes through the interface into the housing and connects to the other end of the aviation connector module. The other end of the cable is connected to the camera of the endoscope. As the crawler carries the camera into the pipe, the winding frame rotates, causing the cable to exit. During this process, the housing and the coding module rotate synchronously to measure the length of the cable exiting. Due to the presence of the bearing, the aviation connector module does not rotate with the housing, thus ensuring the stability of the wiring.

[0015] In this application, when the middle shell rotates, it can drive the output shaft of the encoder to rotate. The encoder can measure the number of rotations of the output shaft, thereby realizing the measurement of the cable output. When the cable enters the housing through the interface, it is connected to the PCB adapter board through the hollow slip ring, and then connected to the aviation connector module through the PCB adapter board.

[0016] Furthermore, the housing includes an upper shell, a middle shell, and a bottom shell, which are connected sequentially by screws. The aviation connector module is mounted on the upper shell via a bearing, and the encoder base is installed inside the middle shell. A mounting plate is provided at the bottom of the bottom shell, and the winding frame is mounted on the bottom shell via the mounting plate. The fixing component is a fixing nut, and the mounting plate is locked to the bottom shell by the fixing nut.

[0017] Furthermore, the aviation connector module includes an aviation head, an aviation head cover, and an aviation head base. The aviation head is connected to the PCB adapter board and is installed on the aviation head base via the aviation head cover. The aviation head base is fixed to the mounting plate by nuts and installed in the upper shell via bearings.

[0018] Furthermore, the braking structure includes a brake screw, a brake nut, and a knob. The brake nut is fixed to the main frame, and the brake screw is threaded onto the brake nut. The outer wall of the upper shell is provided with a brake groove. One end of the brake screw is fitted with the knob, and the other end abuts against the inner wall of the brake groove. In this application, by turning the brake screw, the front end of the brake screw is tightly abutted against the inner wall of the brake groove of the upper shell, fixing the rotating shell and achieving braking of the winding frame. When it is necessary to rotate the winding frame, simply loosen the brake screw to disengage it from the brake groove.

[0019] Furthermore, during installation of the winding spool of this application: first, place the assembled multi-functional component in the middle below the main frame and fix it with screws; then, place the winding frame in the bottom shell below the multi-functional component and tighten the fixing nut for fixation. Rotating the knob of the brake screw causes the brake screw to fit tightly into the brake groove of the upper shell of the multi-functional component, locking the winding frame so that it cannot rotate.

[0020] When disassembling the winding reel as a whole: unscrew the fixing nut to secure and remove the winding frame, and unscrew the middle screw of the main frame to remove the multi-functional component.

[0021] Cable connection: The cable of the aviation head and the hollow slip ring, encoder are connected to the PCB adapter board. The cable at the other end of the hollow slip ring passes through the interface of the bottom shell and is connected to the cable of the winding frame.

[0022] The beneficial effects of this utility model are: compared with the prior art, the winding frame and the main frame of this application can be easily disassembled and assembled, thereby facilitating the replacement and maintenance of various functional components; at the same time, the braking structure can control the winding frame to stop rotating, thereby facilitating the control of wire output and retraction.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] To achieve the above objectives, the technical solution of this utility model is as follows:

[0029] See Figure 1-3 As shown, this embodiment provides a detachable endoscope winding reel, comprising:

[0030] Winding frame 2 for winding cable 1;

[0031] Main frame 3 for mounting winding frame 2;

[0032] Braking structure 4 for controlling the winding frame 2 to stop rotating;

[0033] Multifunctional component 5 with rotating meter counting function;

[0034] The winding frame 2 is movably mounted on the main frame 3 and is detachably connected to the main frame 3; the braking structure 4 is located on the side of the winding frame 2.

[0035] The main frame 3 is equipped with a mounting plate 6. The multi-functional component 5 is connected to the mounting plate 6 by screws, and then it is detachably installed on the main frame 3 via the mounting plate 6.

[0036] Furthermore, the multifunctional component 5 includes a housing 51, an aviation connector module 52, an encoding module 53, a bearing 54, and a fixing component 55. The encoding module 53 includes a PCB adapter board 531, an encoder 532, an encoder base 533, a hollow slip ring 534, and a D-shaped swivel cover 535. The aviation connector module 52 is fixed on the mounting plate 6 and is installed at one end of the housing 51, and is rotatably connected to the housing 51 via the bearing 54. The winding frame 2 is detachably installed on the housing 51 and locked by the fixing component 55. The encoding module 53 is disposed inside the housing 51. The housing 51 also has an interface 54 for connecting the cable 1 to the aviation connector module 52.

[0037] Furthermore, the encoder 532 is mounted on the encoder base 533, and the output shaft of the encoder 532 is fixed to the middle shell 512 through the D-shaped rotating shaft cover 535. The hollow slip ring 534 is mounted on the output shaft of the encoder 532, and the encoder 532, the aviation connector module 52, and the hollow slip ring 534 are all electrically connected to the PCB adapter board 531. In this embodiment, when the middle shell 512 rotates, it can drive the output shaft of the encoder 532 to rotate. The encoder 532 can measure the number of rotations of the output shaft, thereby realizing the measurement of the cable 1 output. When the cable 1 enters the shell 51 through the interface 54, it is connected to the PCB adapter board 531 through the hollow slip ring 534, and then connected to the aviation connector module 52 through the PCB adapter board 531.

[0038] It should be noted that the hollow slip ring 534 used in this embodiment is a conventional electric slip ring, used for electrical connection in a rotating state. For its specific structure and working principle, please refer to the Baidu Encyclopedia entry for "slip ring", which will not be described in detail in this embodiment.

[0039] In this embodiment, one end of the aviation connector module is connected to the endoscope host. Cable 1 is wound around the winding frame 2. One end of cable 1 passes through the interface 54 and enters the housing 51 to connect with the other end of the aviation connector module. The other end of cable 1 is connected to the camera of the endoscope. As the crawler carries the camera into the pipe, the winding frame 2 rotates to drive cable 1 out. During this process, the housing 51 and the encoding module 53 rotate synchronously to measure the length of cable 1 out. Due to the presence of the bearing 54, the aviation connector module 52 does not rotate with the housing 51, thus ensuring the stability of the wiring.

[0040] The above structure facilitates the assembly and disassembly of the winding frame 2 and the multi-functional component 5. Meanwhile, the encoding module 53 has a metering function, which can measure the cable's outgoing length. The brake structure 4 can control the rotation of the winding frame 2, thereby controlling the inlet and outlet of the winding reel, thus achieving a multi-functional effect.

[0041] Furthermore, the housing 51 includes an upper housing 511, a middle housing 512, and a bottom housing 513. The upper housing 511, the middle housing 512, and the bottom housing 513 are connected in sequence by screws. The aviation connector module 52 is mounted on the upper housing 511 via a bearing 54, and the encoder base 533 is mounted inside the middle housing 512. The bottom of the bottom housing 513 is provided with a mounting plate 514. The winding frame 2 is mounted on the bottom housing 513 via the mounting plate 514. The fixing member 55 is a fixing nut, and the mounting plate 514 is locked onto the bottom housing 513 by the fixing nut.

[0042] Furthermore, the aviation connector module 52 includes an aviation head 521, an aviation head cover 522, and an aviation head base 523. The aviation head 521 is connected to the PCB adapter board 531 and is installed on the aviation head base 523 through the aviation head cover 522. The aviation head base 523 is fixed to the mounting plate 6 by nuts and installed in the upper shell 511 through the bearing 54.

[0043] Furthermore, the braking structure 4 includes a brake screw 41, a brake nut 42, and a knob 43. The brake nut 42 is fixed to the main frame 3, and the brake screw 41 is threaded onto the brake nut 42. The outer wall of the upper shell 511 is provided with a brake groove 515. One end of the brake screw 41 is fitted with the knob 43, and the other end abuts against the inner wall of the brake groove 515. In this embodiment, by turning the brake screw 41, the front end of the brake screw 41 is tightly abutted against the inner wall of the brake groove 515 of the upper shell 511, fixing the rotating shell 51 and achieving braking of the winding frame 2. When it is necessary to rotate the winding frame 2, simply loosen the brake screw 41 to disengage it from the brake groove 515.

[0044] Furthermore, during installation of the winding reel in this embodiment: first, place the assembled multi-functional component 5 in the middle below the main frame 3 and fix it with screws; then, place the winding frame 2 in the bottom shell 513 below the multi-functional component 5 and tighten the fixing nut for fixation. Rotate the knob 43 of the brake screw 41, and the brake screw 41 will fit tightly with the brake groove 515 of the upper shell 511 of the multi-functional component 5, locking the winding frame 2 so that it cannot rotate.

[0045] When disassembling the entire winding reel in this embodiment: unscrew the fixing nut to fix and remove the winding frame 2, and unscrew the middle screw of the main frame 3 to remove the multi-functional component 5.

[0046] Cable 1 connection: The cable at the aviation head end, hollow slip ring 534, encoder 532 are connected to the PCB adapter board, and the cable at the other end of the hollow slip ring 534 passes through the interface 54 of the bottom shell 513 and is connected to the cable on the winding frame 2.

[0047] Compared with the prior art, this embodiment allows for the detachment and assembly of the winding frame 2, the multi-functional component 5, and the main frame 3, thereby facilitating the replacement and maintenance of each functional component; at the same time, the braking structure 4 can control the winding frame 2 to stop rotating, thereby facilitating the control of wire output and retraction.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
