In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0024] Example 1

[0025] like Figure 1-6 As shown, it is the first embodiment of the utility model, which provides a new type of fastening structure brake for a reduction motor, including a brake body 1, the brake body 1 includes a first component 11, a second component 12 and a third component 13, the front of the first component 11 is fixedly connected with a threaded tube 2, the number of the threaded tubes 2 is three, the front of the third component 13 is provided with a through groove 3, the inner cavity of the through groove 3 is provided with a fastening bolt 4, the rear end of the fastening bolt 4 extends to the inner cavity of the threaded tube 2, and is threadedly connected with the inner cavity of the threaded tube 2, and the inner cavity of the fastening bolt 4 is provided with a fastening mechanism 5;

[0026] The fastening mechanism 5 includes a hollow plate 501, which is arranged in the inner cavity of the fastening bolt 4. Positioning grooves 502 are opened on both sides of the hollow plate 501. A positioning plate 503 is fixedly connected to the back side of the inner cavity of the threaded tube 2. The front end of the positioning plate 503 extends to the inner cavity of the hollow plate 501. Tough blocks 504 are fixedly connected on both sides of the positioning plate 503. One side of the tough block 504 extends to the inner cavity of the positioning groove 502 and engages with the inner cavity of the positioning groove 502.

[0027] like Figure 1-6As shown, the first component 11, the second component 12 and the third component 13 are used to constitute the brake body, the through groove 3 is used to install the fastening bolt 4, and provides space for the fastening bolt 4 to move. Through the cooperation of the threaded tube 2 and the fastening bolt 4, the first component 11, the second component 12 and the third component 13 can be fastened, and the stability of the connection between the three is improved. The fastening mechanism 5 can fix the fastening bolt 4 inside the threaded tube 2. Even if the fastening bolt 4 produces thread slippage due to long-term vibration, it will not fall off from the inside of the threaded tube 2 under the positioning action of the fastening mechanism 5, thereby ensuring that the brake body 1 can operate normally.

[0028] Example 2

[0029] Reference Figure 3 and 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0030] In this embodiment, a receiving groove 505 is provided on the front side of the fastening bolt 4, and the inner cavity of the receiving groove 505 is movably connected to the support plate 506 through a bearing. The front end of the hollow plate 501 extends to the inner cavity of the receiving groove 505 and is fixedly connected to the back side of the support plate 506.

[0031] A pressing block 507 is slidably connected to the inner cavity of the receiving groove 505 and located on the front side of the supporting piece 506 , and the front end of the pressing block 507 extends to the outside of the fastening bolt 4 .

[0032] like Figure 3 and 4 As shown, during the process of gradually installing the fastening bolt 4 into the threaded tube 2, the positioning plate 503 will gradually be inserted into the hollow plate 501. During the insertion of the positioning plate 503, the tough block 504 will be squeezed by the inner wall of the hollow plate 501 and move closer to the positioning plate 503. When the positioning plate 503 is fully inserted into the hollow plate 501, the tough block 504 no longer contacts the inner wall of the hollow plate 501, so that it can be reset into the inner cavity of the positioning groove 502 and engage with it, thereby fixing the positioning plate 503 inside the hollow plate 501, thereby positioning the fastening bolt 4.

[0033] Example 3

[0034] Reference Figure 3 and 6 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0035] In this embodiment, a spring 508 is disposed in the inner cavity of the accommodating groove 505 and between the supporting sheet 506 and the pressing block 507 , and the front and back sides of the spring 508 are fixedly connected to the pressing block 507 and the supporting sheet 506 , respectively.

[0036] Slide grooves 509 are provided on both sides of the inner cavity of the hollow plate 501, and the inner cavity of the slide groove 509 is slidably connected to a sliding plate 510, and the inner cavity of the sliding plate 510 is fixedly connected to an anti-slip block 511, and the front end of the sliding plate 510 penetrates into the inner cavity of the accommodating groove 505 and is fixedly connected to the back side of the pressing block 507.

[0037] The number of the positioning grooves 502 , the number of the toughness blocks 504 and the number of the anti-dropping blocks 511 are all four.

[0038] like Figure 3 and 6 As shown, during the installation of the fastening bolt 4, the pressing block 507 is pressed, and the pressing block 507 drives the sliding plate 510 to move backward in the inner cavity of the slide groove 509 until the anti-slip block 511 moves out of the inner cavity of the positioning groove 502. At this time, the pressing block 507 will squeeze the spring 508 and cause the spring 508 to deform. Since the supporting plate 506 is movably connected to the inner cavity of the accommodating groove 505 through the bearing, the angle of the fastening mechanism 5 does not change during the rotation of the fastening bolt 4. When the toughness block 504 is inserted into the inner cavity of the positioning groove 502 and engaged with it, the pressing block 507 is released. At this time, the restoring elastic force of the spring 508 drives the pressing block 507 and the sliding plate 510 to reset, and the anti-slip block 511 is inserted into the rear end of the toughness block 504 to prevent it from falling off.

[0039] When in use, during the process of gradually installing the fastening bolt 4 into the threaded tube 2, the pressing block 507 is pressed, and the pressing block 507 drives the sliding plate 510 to move backward in the inner cavity of the slide groove 509 until the anti-dropping block 511 moves out of the inner cavity of the positioning groove 502. At this time, the pressing block 507 will squeeze the spring 508 and cause the spring 508 to deform. Since the supporting sheet 506 is movably connected to the inner cavity of the receiving groove 505 through the bearing, the angle of the fastening mechanism 5 will not change during the rotation of the fastening bolt 4. During the installation process, the positioning plate 503 will gradually be inserted into the interior of the hollow plate 501. During the insertion of the positioning plate 503, the toughness block 504 will move closer to the positioning plate 503 due to the squeezing of the inner wall of the hollow plate 501. When the positioning plate 503 is fully inserted into the interior of the hollow plate 501, the tough block 504 no longer contacts the inner wall of the hollow plate 501, so that it can be reset into the inner cavity of the positioning groove 502 and engage with it, thereby fixing the positioning plate 503 inside the hollow plate 501, so as to position the fastening bolt 4. When the tough block 504 is inserted into the inner cavity of the positioning groove 502 and engages with it, the pressing block 507 is released. At this time, the reset elastic force of the spring 508 drives the pressing block 507 and the sliding plate 510 to reset, and the anti-fall-off block 511 is inserted into the rear end of the tough block 504 to prevent it from falling off.
