[0029] The preferred embodiment of the novel antimony-free friction reducing device provided by the utility model is as follows Figures 1 to 5 As shown: a new antimony-free friction reduction device, including a support plate 4, a pillar 3 is fixedly connected to the middle position of the top of the support plate 4, a connecting seat 6 is fixedly connected to the top of the pillar 3, mounting components 2 are arranged on both sides of the connecting seat 6, a bearing seat 8 is movably connected to one side of the inner wall of the connecting seat 6, a pulley 1 is rotatably connected to one side of the bearing seat 8, and a cleaning component 7 is arranged at the lower end of the back side of the connecting seat 6.

[0030] The mounting assembly 2 includes a card slot 201, which is provided at the upper end of the inner wall of the connecting seat 6, and the upper ends of both sides of the connecting seat 6 are fixedly connected with mounting seats 203, and the interior of the mounting seat 203 is movably connected with a sliding block 205, and one side of the sliding block 205 is fixedly connected with a mounting block 204 extending to the inside of the card slot 201, and the other side of the sliding block 205 is fixedly connected with a pull rod 202 extending to the outside of the mounting seat 203, and the surface of the pull rod 202 on one side of the sliding block 205 is wound with a mounting spring 206, and the mounting spring One end of 206 is fixedly connected to the inner wall of the mounting seat 203, and a mounting hole 207 is opened on one side of the bearing seat 8. By utilizing the engagement between the bearing seat 8 and the inside of the card slot 201 and the elastic force of the mounting spring 206, the sliding block 205 slides and drives the mounting block 204 to be stuck into the mounting hole 207 or detached from the inside thereof, thereby realizing the rapid disassembly and assembly action between the pulley 1 and the bearing seat 8 and the connecting seat 6, which is convenient for the disassembly and assembly, maintenance or replacement of the pulley 1, and avoiding the decrease of the friction reduction effect due to damage of the pulley 1.

[0031] In this embodiment, the cross-section of the slot 201 is inverted convex, and a snap-fit ​​structure is formed between the bearing seat 8 and the interior of the slot 201. The inverted convex slot 201 can be used to achieve preliminary snap-fitting and disassembly between the bearing seat 8 and the interior of the slot 201.

[0034] On the basis of Example 1, a preferred embodiment of the novel antimony-free friction reducing device provided by the present invention is as follows: Figures 1 to 5As shown: the cleaning component 7 includes a fixed groove 704, which is opened at the lower ends of both sides of the back side of the connecting seat 6, one end of the inner wall of the fixed groove 704 is fixedly connected to a sliding rod 708, and a fixed spring 705 is wound around the lower end of the surface of the sliding rod 708, and a sliding plate 703 is slidably connected to the surface of the sliding rod 708 at one end of the fixed spring 705, and one end of the sliding plate 703 extends to the outside of the fixed groove 704 and is fixedly connected to a cleaning plate 701, and the tip of the cleaning plate 701 is used to scrape off excessive oil and impurities adhering to the surface of the pulley 1, especially metal debris or filaments adsorbed by static electricity, thereby preventing excessive adhesion of oil and impurities on the surface of the pulley 1, causing an increase in friction between the pulley 1 and hard objects, or scratches on the hard objects or the surface of the pulley 1 caused by metal debris or filaments.

[0035] In this embodiment, the cleaning plate 701 is inclined at an angle of sixty degrees to the vertical direction. The lower end of one side of the cleaning plate 701 is fixedly connected to one end of the sliding plate 703 by bolts. The inclined cleaning plate 701 is used to scrape off oil and impurities and guide them to make them easier to discharge.

[0036] In this embodiment, a finger groove 702 is provided at the middle position of the lower end of the cleaning plate 701. The finger groove 702 has rounded corners. The finger groove 702 allows the user to hook his finger into the finger groove 702 to drive the cleaning plate 701 to slide.

[0037] In this embodiment, a sliding groove 707 is provided on the inner wall of the fixed groove 704, and a slider 706 is fixedly connected to one end of the sliding plate 703 and slides in cooperation with the inside of the sliding groove 707. The sliding of the slider 706 on the surface of the sliding groove 707 improves the stability of the sliding up and down sliding of the sliding plate 703.

[0038] Furthermore, reserved screw holes 5 are provided on both sides of the top of the support plate 4 . The shape of the reserved screw holes 5 in a top view is O-shaped. The O-shaped reserved screw holes 5 facilitate the installation and fixation of the support plate 4 by external bolts.

[0039] In addition, the cross-section of the connecting seat 6 is U-shaped, and the inner bottom wall of the connecting seat 6 is sloped. The sloped connecting seat 6 allows oil impurities, metal debris or filaments that fall onto the inner wall of the connecting seat 6 to be discharged more smoothly.

[0040] The working principle and use process of the utility model are as follows: first, the sliding block 205 is driven to slide by pulling the pull rod 202 until the mounting block 204 is completely separated from the inside of the slot 201, and then the bearing seat 8 can be clamped into the inside of the slot 201, and then the pull rod 202 is released, and the elastic force of the mounting spring 206 is used to make the sliding block 205 slide and drive the mounting block 204 to clamp into the inside of the mounting hole 207, so as to achieve the limited fixation of the bearing seat 8 after sliding, and then the installation and fixation between the pulley 1 and the connecting seat 6 can be achieved. When the pulley 1 needs to be disassembled, the above operation can be performed in reverse, so as to achieve the quick disassembly and assembly action of the pulley 1, which is convenient for the disassembly and assembly maintenance or replacement of the pulley 1, and avoids the decrease of the friction reduction effect caused by the damage of the pulley 1.

[0041] At the same time, after the pulley 1 is installed, the elastic force of the fixed spring 705 is utilized to make the sliding plate 703 slide and drive the tip of the cleaning plate 701 to approach the surface of the pulley 1, so that the cleaning plate 701 will not hinder the rotation of the pulley 1. After that, the rotating pulley 1 can be utilized to reduce the friction between the pillar 3 and the hard object, reduce the wear and tear of the hard object on the pillar 3, and extend the service life of the pillar 3. In addition, during the rotation of the pulley 1, a certain amount of oily impurities adhere to the surface of the pulley 1, causing its diameter to increase, and then it can be scraped off by the tip of the cleaning plate 701, especially the metal debris or filaments adsorbed by static electricity, thereby preventing the oily impurities from adhering too much to the surface of the pulley 1, causing the friction between the hard object and the metal debris or filaments to increase, or causing scratches on the surface of the hard object or the pulley 1 by the metal debris or filaments. At the same time, the elastic force of the fixed spring 705 is utilized to make some oily impurities that adhere too tightly contact the cleaning plate 701, and the cleaning plate 701 will be forced to slide down, thereby preventing the cleaning plate 701 from being stuck with the oily impurities that adhere too tightly, causing the pulley 1 to rotate poorly.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
