When turning the fastening screws, they need to be tightened one by one, making the disassembly and assembly of the reducer very troublesome. The fastening screws are also prone to rust. At the same time, existing reducers are easily affected by external interference during use, which can affect the normal operation of the reducer. To this end, we propose an anti-interference spindle drive reducer. Utility Model Content

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0024] The embodiment of the utility model discloses an anti-interference main shaft transmission reducer.
[0025] The utility model provides Figure 1-4 The anti-interference spindle transmission reducer shown includes a base 1 and a reducer 3. A mounting plate 2 is installed on the top outer wall of the base 1. There are two mounting plates 2, and the two mounting plates 2 are symmetrically arranged on both sides of the base 1. The two mounting plates 2 are each provided with a guide groove 6. A guide bar 4 is provided on the outer wall of the reducer 3. The reducer 3 is engaged with the guide groove 6 through the guide bar 4. A shielding cover is provided on the reducer 3. A limiting hole 5 is provided on the guide bar 4. A groove 10 is provided on the inner wall of the guide groove 6. A limiting mechanism 7 is provided on the mounting plate 2. The limiting mechanism 7 includes a limiting block 11, a connecting rod 12 and a spring 13. The limiting block 11 is slidably connected to the groove 10. The position and size of the limiting block 11 correspond to those of the limiting hole 5. One end of the connecting rod 12 is fixedly connected to the outer wall of the limiting block 11, and the other end of the connecting rod 12 passes through the outside of the mounting plate 2.
[0026] The utility model provides an anti-interference spindle transmission reducer, in which the spring 13 is nested on the connecting rod 12, and the spring 13 is pressed between the outer wall of the limit block 11 and the inner wall of the groove 10. Through the elastic force of the spring 13, a certain thrust can always be applied to the limit block 11, so that the limit block 11 can always maintain a clamping state with the limit hole 5, avoiding separation between the two and affecting the stability of the installation.
[0027] The utility model provides an anti-interference spindle transmission reducer, a connecting rod 12 passes through to the outside of the mounting plate 2 and is rotatably connected to a pull ring 14 at one end, the pull ring 14 and the connecting rod 12 are integrated into a structure, and a rubber sleeve is nested on the pull ring 14. The pull ring 14 can conveniently drive the connecting rod 12 and the limit block 11 to move, thereby improving the convenience of operation.
[0028] The utility model discloses an anti-interference spindle transmission reducer. A fixing rod 15 is provided on the outer wall of a pull ring 14. A fixing plate 8 is provided on the outer wall of a mounting plate 2. An arcuate groove 9 is formed on the fixing plate 8. The fixing rod 15 and the arcuate groove 9 are aligned in position and size. When the reducer 3 is disassembled, the fixing rod 15 can be snapped into the arcuate groove 9, thereby facilitating subsequent operations by the operator without having to constantly pull the pull ring 14 by hand.
[0029] The utility model provides an anti-interference spindle transmission reducer, the groove 10 is a rectangular structure, the limit block 11 is consistent with the size and structure of the groove 10, and can prevent the limit block 11 from rotating randomly during use and affecting the use effect.
[0030] The utility model provides an anti-interference spindle transmission reducer, and both the limit block 11 and the guide bar 4 are provided with inclined surfaces. The inclined surface on the limit block 11 is inclined upward, and the inclined surface on the guide bar 4 is inclined downward, which can facilitate the guide bar 4 to be inserted into the guide groove 6.
[0031] When in use, align the guide bar 4 on the reducer 3 with the guide groove 6, and then the reducer 3 will move downward. During the downward movement, the guide bar 4 will contact the limit block 11. Since both are provided with inclined surfaces, the guide bar 4 will push the limit block 11 into the interior of the groove 10. After the reducer 3 is installed in place, the limit hole 5 on the guide bar 4 will move to the limit block 11. At this time, the limit block 11 loses the external thrust, so it will return to its original position under the elastic action of the spring 13 and remain in a locked state with the limit hole 5 to fix the reducer 3. During use of the reducer 3, the shielding cover provided on its surface can effectively shield external interference to ensure its normal operation. When the reducer 3 needs to be disassembled for maintenance, pull the pull ring 14 and rotate the pull ring 14 so that the fixing rod 15 on the pull ring 14 moves into the arc groove 9. At this time, the limit block 11 is disconnected from the limit hole 5, and the reducer 3 loses its limiting and fixing effect. Then the reducer 3 can be disassembled.
[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
