Description

Technical Field

[0001] This utility model relates to the field of detection module technology, and in particular to a waterproof structure for an incremental encoder detection module. Background Technology

[0002] An incremental encoder detection module is an electronic device used to process incremental encoder signals. It can accurately detect the A-phase, B-phase, and Z-phase pulse signals output by the incremental encoder, and amplify, shape, and filter these signals to convert them into standard digital signals that the controller can recognize, thereby obtaining accurate position, speed, and direction information.

[0003] Currently, existing incremental encoder detection modules on the market are susceptible to damage from external factors during use, such as rain or water immersion in the equipment. This can lead to internal circuit short circuits, abnormal current paths, and ultimately, burnout of electronic components, making them unsuitable for future use. Although incremental encoder detection modules incorporate certain sealing structures, such as sealing strips or gaskets, to enhance waterproofing, the aging of these sealing strips over time can also significantly reduce their waterproofing performance.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] This invention provides a waterproof structure for an incremental encoder detection module, which solves the problem of insufficient waterproof performance of traditional incremental encoder detection modules. The specific solution is as follows:

[0006] A waterproof structure for an incremental encoder detection module includes a sealed base, a waterproof outer layer fixedly connected to the top of the sealed base, traction rods fixedly connected to both sides of the sealed base, an inner layer fixedly installed in the middle of the sealed base, and the inner layer and the waterproof outer layer being fitted together; a top cover is slidably connected to the middle of the two traction rods, a covering layer is fixedly installed at the bottom of the top cover, the covering layer is a tensile structure, and the bottom end of the covering layer is fixedly connected to the top end of the waterproof outer layer; docking plates are fixedly connected to both sides of the top cover, and locking components are provided on the docking plates, the locking components being interconnected with the incremental encoder detection module.

[0007] As a preferred technical solution of this utility model, the locking assembly includes a bracket one and a bracket two, which are respectively installed on the top wall of the face monster docking plate. The middle part of the bracket one is rotatably connected to a winding rod, and multiple layers of binding rope are wound on the winding rod. The binding rope is made of rubber, and the ends of the binding rope have pre-set locking holes.

[0008] As a preferred technical solution of this utility model, the second bracket is a plate structure. The end of the second bracket is rotatably connected to a locking rod. A rotating handle is provided on the outer side of the second bracket. The rotating handle is connected to the locking rod. A slot is opened in the middle of the locking rod. A locking screw is preset at the top of the locking rod. The slot is used for the binding rope to pass through, and the screw is inserted into the locking hole at the end of the binding rope for fixation.

[0009] As a preferred technical solution of this utility model, the docking plate has a pre-set limiting hole in the middle, the docking plate and the traction rod are interlocked through the limiting hole, the docking plate and the traction rod are slidably connected to each other, and a limiting hole is pre-set on the side wall of the traction rod, in which a limiting rod is inserted to limit and fix the docking plate.

[0010] As a preferred technical solution of this utility model, a washer 1 and a washer 2 are fixedly installed in the middle of the inner layer. The washer 1 and the washer 2 are made of rubber, and multiple fixing rods are fixedly connected between the washer 1 and the washer 2.

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0024] See Figures 1-4This utility model provides a waterproof structure for an incremental encoder detection module, including a sealed base 1, a waterproof outer layer 2 fixedly connected to the top of the sealed base 1, traction rods 6 fixedly connected to both sides of the sealed base 1, an inner layer 3 fixedly installed in the middle of the sealed base 1, and the inner layer 3 and the waterproof outer layer 2 being fitted together; a top cover 7 is slidably connected to the middle of the two traction rods 6, a covering layer 8 is fixedly installed at the bottom of the top cover 7, the covering layer 8 is a tension structure, and the bottom end of the covering layer 8 is fixedly connected to the top end of the waterproof outer layer 2; docking plates 9 are fixedly connected to both sides of the top cover 7, and locking components are provided on the docking plates 9, which are connected to the incremental encoder detection module.

[0025] The locking assembly includes bracket 10 and bracket 2 14. Bracket 10 and bracket 2 14 are respectively installed on the top wall of the face monster docking plate 9. The middle part of bracket 10 is rotatably connected to a winding rod. Multiple layers of binding rope 11 are wound on the winding rod. The binding rope 11 is made of rubber and has a locking hole at the end.

[0026] The bracket 2 14 is a plate structure. The end of the bracket 2 14 is rotatably connected to the locking rod 12. A rotating handle is provided on the outside of the bracket 2 14. The rotating handle is connected to the locking rod 12. A slot 13 is opened in the middle of the locking rod 12. A locking screw is preset at the top of the locking rod 12. The slot of the slot 13 is used for the binding rope 11 to pass through, and the screw is inserted into the locking hole at the end of the binding rope 11 for fixing.

[0027] It should be noted that before using the binding rope 11, the entire device needs to be connected to the detection module. Then, pull the binding rope 11 and insert one end of the binding rope 11 into the slot 13. The locking bolt at the top of the locking rod 12 passes through the binding rope 11 and is threadedly connected to the locking rod 12 to ensure the connection and fixation of the binding rope 11. Next, slowly rotate the handle to make the locking rod 12 move the binding rope 11, so that the binding rope 11 is tightened around the detection module. The end of the rotating handle and the side wall of the bracket 14 are also provided with through holes and screws as limiting components (not shown in the figure) to fix the locking rod 12 after locking, thereby preventing the binding rope 11 from springing back.

[0028] The middle of the docking plate 9 has a pre-set limiting hole. The docking plate 9 and the traction rod 6 are interlocked through the limiting hole and are slidably connected. The side wall of the traction rod 6 has a pre-set limiting hole. A limiting rod is inserted into the limiting hole to limit and fix the docking plate 9. When the top cover 7 moves from bottom to top, the movement of the top cover 7 can drive the covering layer 8 to unfold, thereby forming a covering treatment for the waterproof outer layer 2 and the inner layer 3, as a secondary protection, and improving the overall sealing performance.

[0029] As the top cover 7 continues to move and moves above the limiting hole on the side wall of the traction rod 6, the screw passes through the limiting hole. At this time, the top of the screw contacts the bottom of the top cover 7, so the top cover 7 is limited and cannot descend due to its own weight.

[0030] Washer 1 5 and Washer 2 4 are fixedly installed in the middle of the inner layer 3. Washer 1 5 and Washer 2 4 are made of rubber, and multiple fixing rods 15 are fixedly connected between Washer 1 5 and Washer 2 4. Washer 1 5 and Washer 2 4 cooperate with each other to further enhance the sealing of the inner layer 3. At the same time, multiple fixing rods 15 are used to connect Washer 1 5 and Washer 2 4, thereby ensuring that the position between the two will not shift and improving the firmness.

[0031] After the top cover 7 moves upward to the position near the top of the traction rod 6, the covering layer 8 is stretched upward and covers the waterproof outer layer 2 and inner layer 3. The inner side of the top cover 7 has a pre-set thread, and the end of the small incremental encoder detection module is a circular structure. At the same time, it can be rotated using the thread on the inner side of the top cover 7, thereby docking and fixing the whole device with the detection module, improving the overall waterproof performance.

[0032] Furthermore, by setting a waterproof outer layer 2 and an inner layer 3 on the top of the sealing base 1, and by setting a gasket 5 and a gasket 4 inside the inner layer 3 to lock and fix the end of the incremental encoder detection module and achieve effective sealing, the overall waterproof performance is improved; at the same time, a movable covering layer 8 is set on the top of the waterproof outer layer 2 as an external secondary protection, further improving the waterproof effect of the incremental encoder detection module.

[0033] In addition, by setting pull-out binding ropes 11 and locking rods 12 for locking the binding ropes 11 on the two mating plates 9 on both sides of the top cover 7, the overall waterproof structure can be more firmly locked onto the incremental encoder detection module, preventing it from falling off later.
