Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial endoscopes, and in particular to an LED lighting device for industrial endoscopes. Background Technology
[0002] Industrial endoscopes are non-destructive testing tools used in industrial inspections. Utilizing optical and electronic technologies, they allow for in-depth observation of the interior of the object being inspected without damaging it. Various types are available, including straight-arm endoscopes, fiber optic endoscopes, and video endoscopes, to suit different inspection scenarios. Through endoscopes, the internal structure and condition of components can be clearly viewed, accurately detecting defects such as cracks, corrosion, and wear. They are widely used in industries such as aerospace, automotive manufacturing, power, and petrochemicals, effectively improving inspection efficiency and accuracy, reducing equipment failure risks, and ensuring the safe and stable operation of industrial production. They are an indispensable and crucial inspection device in the industrial field.
[0003] However, in the existing technology, since the LED lighting module of industrial endoscopes is mostly directly packaged inside the endoscope, when maintenance is required, the lighting module and imaging module must be removed as a whole. This process is complicated and greatly increases the difficulty of maintenance. Utility Model Content
[0004] The purpose of this invention is to provide an LED lighting device for industrial endoscopes to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED lighting device for an industrial endoscope, comprising a housing, an imaging module disposed inside the housing, a slot disposed inside the imaging module, a lens disposed on the left side of the imaging module, a mounting groove provided on the inner side of the housing, a locking hole provided on one side of the mounting groove, a mounting block disposed inside the mounting groove, an lighting module fixedly connected to one side of the mounting block, and a light strip disposed on the inner side of the lighting module;
[0006] The mounting block has a movable block inside, a locking block is fixedly connected to the rear side of the movable block, a connecting sleeve is fixedly connected to the other side of the movable block, a short rod is fixedly connected to the rear side of the interior of the mounting block, and a spring is sleeved on the outside of the short rod.
[0007] Preferably, a positioning strip is fixedly connected to the outer side of the housing, a limit ring is fixedly connected to the outer side of the housing near the positioning strip, a rotating ring is provided outside the limit ring, a fixing ring is fixedly connected to one side of the rotating ring, a lens frame is provided on the left side of the housing, a lens is provided on the left side of the lens frame, and a positioning groove is provided on the inner side of the lens frame.
[0008] Preferably, the number of mounting blocks is two sets, and they are symmetrically arranged about the center line of the lighting module.
[0009] Preferably, the connecting sleeve slides outside the short rod via a moving block, a locking block, and a spring.
[0010] Preferably, the fixing ring is rotatably connected to the housing via a limiting ring.
[0011] Preferably, the internal thread of the fixing ring is adapted to the external thread of the mirror frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] By pushing the locking block, the locking block drives the moving block and connecting sleeve to move to one side and compresses the spring. During this process, the locking block disengages from the inside of the locking hole, turning the housing downwards. The lighting module slides out of the housing under the action of gravity, completing the disassembly. Similarly, during installation, the mounting block is slid into the inside of the mounting groove. After it reaches the preset position, the spring rebounds and pushes the connecting sleeve and moving block to move in the opposite direction. The locking block passes through the locking hole again, realizing the installation and fixation of the lighting module. The mounting block, locking block, moving block, spring, connecting sleeve and other components enable the lighting module to be quickly installed and removed, thus enabling timely maintenance and reducing the difficulty of maintenance.
[0014] By rotating the retaining ring, the frame and lens move to one side under the action of its internal threads, separating them from the housing. At this point, the user can clean them. Similarly, during assembly, the positioning groove on the inside of the frame slides along the outside of the positioning strip and the rotating ring rotates in the opposite direction. The retaining ring then rotates in the opposite direction and is once again fitted onto the outside of the frame, completing the assembly of the frame and the housing. In addition, the positioning groove and positioning strip effectively prevent the frame from rotating during use, improving stability during use. The lens can be installed and removed through components such as the limiting ring, rotating ring, retaining ring, and frame, which allows for cleaning when stains appear and also improves cleaning efficiency.

Detailed Implementation
[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0024] Example 1
[0025] Please see Figures 1-7 This utility model provides a technical solution: an LED lighting device for an industrial endoscope, including a housing 1, an imaging module 2 inside the housing 1, a slot 3 inside the imaging module 2, a lens 4 on the left side of the imaging module 2, a mounting groove 5 on the inner side of the housing 1, a locking hole 6 on one side of the mounting groove 5, a mounting block 9 inside the mounting groove 5, an illumination module 7 fixedly connected to one side of the mounting block 9, a light strip 8 inside the illumination module 7, a moving block 10 inside the mounting block 9, a locking block 11 fixedly connected to the rear side of the moving block 10, a connecting sleeve 12 fixedly connected to the other side of the moving block 10, a short rod 13 fixedly connected to the rear side of the inner side of the mounting block 9, and a spring 14 sleeved on the outside of the short rod 13. There are two sets of mounting blocks 9, which are symmetrically arranged about the center line of the illumination module 7. The connecting sleeve 12 slides outside the short rod 13 through the moving block 10, the locking block 11, and the spring 14.
[0026] Specifically, pushing the locking block 11 causes the moving block 10 and connecting sleeve 12 to move to one side and compress the spring 14. During this process, the locking block 11 disengages from the inside of the locking hole 6, causing the housing 1 to face downwards. The lighting module 7 slides out of the housing 1 under gravity, completing the disassembly. Similarly, during installation, the mounting block 9 is slid into the inside of the mounting groove 5. After it reaches the preset position, the spring 14 rebounds and pushes the connecting sleeve 12 and moving block 10 to move in the opposite direction. The locking block 11 passes through the locking hole 6 again, realizing the installation and fixation of the lighting module 7. The mounting block 9, locking block 11, moving block 10, spring 14, connecting sleeve 12 and other components enable the lighting module 7 to be quickly installed and removed, thus enabling timely maintenance and reducing the difficulty of maintenance.
[0027] Example 2
[0028] Please see Figures 1-7 This utility model provides a technical solution: an LED lighting device for an industrial endoscope, wherein a positioning strip 18 is fixedly connected to the outer side of the housing 1, a limiting ring 15 is fixedly connected to the outer side of the housing 1 near the positioning strip 18, a rotating ring 16 is provided outside the limiting ring 15, a fixing ring 17 is fixedly connected to one side of the rotating ring 16, a lens frame 19 is provided on the left side of the housing 1, a lens 21 is provided on the left side of the lens frame 19, a positioning groove 20 is provided on the inner side of the lens frame 19, and the fixing ring 17 is rotatably connected to the housing 1 through the limiting ring 15, and the internal thread of the fixing ring 17 is adapted to the external thread of the lens frame 19.
[0029] Specifically, by rotating the retaining ring 17, the frame 19 and lens 21 move to one side under the action of its internal threads, thus separating them from the housing 1. At this time, the user can clean them. Similarly, during assembly, the positioning groove 20 on the inner side of the frame 19 slides along the outer side of the positioning strip 18 and the rotating ring 16 is rotated in the opposite direction. The retaining ring 17 then rotates in the opposite direction and is once again fitted onto the outer side of the frame 19, completing the assembly of the frame 19 and the housing 1. In addition, the positioning groove 20 and the positioning strip 18 effectively prevent the frame 19 from rotating during use, improving the stability during use. The lens 21 can be installed and removed through components such as the limiting ring 15, rotating ring 16, retaining ring 17, and frame 19, which allows for cleaning when stains appear and also improves cleaning efficiency.
[0030] Working principle: When inspecting the illumination module 7 of this industrial endoscope, pushing the locking block 11 causes the moving block 10 and connecting sleeve 12 to move to one side and compress the spring 14. During this process, the locking block 11 disengages from the inside of the locking hole 6, causing the housing 1 to face downwards. The illumination module 7 slides out of the housing 1 under gravity, completing the disassembly. Similarly, during installation, the mounting block 9 is slid into the inside of the mounting groove 5. After it reaches the preset position, the spring 14 rebounds and pushes the connecting sleeve 12 and moving block 10 to move in the opposite direction. The locking block 11 passes through the locking hole 6 again, realizing the installation and fixation of the illumination module 7. The mounting block 9, locking block 11, moving block 10, spring 14, connecting sleeve 12 and other components enable quick installation and removal of the illumination module 7, thus facilitating timely inspection and reducing the difficulty of inspection. In addition, the imaging module 2 has a slot 3 inside. When installing the illumination module 7, the plug on its rear side... It will be directly inserted into the slot 3 to establish an electrical connection with the imaging module 2, thereby realizing the coordinated control with the imaging module 2. When it is necessary to clean the lens 21 with stains, rotate the fixing ring 17. Under the action of its internal threads, the frame 19 and the lens 21 move to one side, realizing their separation from the housing 1. At this time, the user can clean it. Similarly, when assembling, slide the positioning groove 20 on the inner side of the frame 19 along the outer side of the positioning strip 18 and rotate the rotating ring 16 in the opposite direction. The fixing ring 17 will then rotate in the opposite direction and be sleeved on the outer side of the frame 19 again, completing the assembly of the frame 19 and the housing 1. In addition, the positioning groove 20 and the positioning strip 18 effectively prevent the frame 19 from rotating during use, improving the stability during use. The lens 21 can be installed and removed through the components such as the limiting ring 15, rotating ring 16, fixing ring 17, and frame 19, so that it can be cleaned when stains appear, and the cleaning efficiency can also be improved.
