[0026] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.
[0027] As attached Figure 1-5 As shown, this utility model provides a perfluoropolyether grease storage device, comprising:
[0028] Box 1;
[0029] Box lid 2, which is located on top of box body 1 and is detachably connected to box body 1;
[0030] Rotating shaft 3 is installed inside the box body 1 and is collinear with the axis of the box body 1;
[0031] Rotating sleeve 4 is fitted onto rotating shaft 3 and rotatably connected to rotating shaft 3;
[0032] The scraper 5 is mounted on the rotating sleeve 4. The shape of the scraper 5 is adapted to the contour of the inner wall of the box body 1. The end of the scraper 5 abuts against the inner wall of the box body 1. The scraper 5 is slidably connected to the box body 1.
[0033] When the user removes the grease from the box 1, if there is little grease left, the user can rotate the scraper 5. The scraper 5 will gather the grease adhering to the inner wall of the box 1, making it easier for the user to remove. At the same time, the scraper 5 will also gather the grease that has accumulated in the corners, preventing the grease from accumulating in the corners and making it difficult to remove.
[0034] In this embodiment, a coil spring is sleeved on the rotating shaft 3. The coil spring is located between the rotating shaft 3 and the rotating sleeve 4. The two ends of the coil spring are respectively engaged with the rotating shaft 3 and the rotating sleeve 4, so that the scraper 5 can be reset under the action of the coil spring after the user rotates the scraper 5.
[0035] Specifically, a groove 6 is provided on the side wall of the box body 1, and a sliding rod 9 is provided on the scraper 5. The sliding rod 9 extends into the groove 6 and slides in connection with the groove 6.
[0036] A fixing groove 7 is provided on the side wall of the box body 1. The position of the fixing groove 7 corresponds to the initial position of the scraper 5. One end of the fixing groove 7 is connected to the slide 6, and the other end is connected to the outside. A fixing rod 8 is sleeved inside the fixing groove 7. The first end of the fixing rod 8 passes through the fixing groove 7 and extends into the slide 6. The second end is located outside the box body 1 and is provided with a pressing plate.
[0037] A crossbar 10 is provided at the first end of the fixed rod 8. A rotating rod 11 is provided at the end of the crossbar 10 near the slide rod 9. The rotating rod 11 is rotatably connected to the crossbar 10. A limiting rod 12 is provided on the crossbar 10. The limiting rod 12 is located between the crossbar 10 and the slide rod 9. A tension spring is provided between the limiting rod 12 and the slide rod 9. A protrusion 13 adapted to the rotating rod 11 is provided on the slide rod 9. The protrusion 13 can be L-shaped.
[0038] A limiting plate 14 and a first compression spring are provided on the fixed rod 8. The first compression spring is sleeved on the fixed rod 8, and the limiting plate 14 is located in the fixed groove 7. One end of the first compression spring abuts against the end of the fixed groove 7 near the slide groove 6, and the other end abuts against the limiting plate 14.
[0039] During use, one end of the protrusion 13 on the slide bar 9 is located between the rotating rod 11 and the groove. At this time, the slide bar 9 and the protrusion 13 tend to rotate outward under the influence of the coil spring and the scraper 5. Meanwhile, the rotating rod 11 is restricted by the limiting rod 12 and cannot rotate to the outside of the crossbar 10, thus restricting the outward rotation of the slide bar 9 and the protrusion 13 and keeping the scraper 5 stationary. When the user presses the fixing rod 8, the fixing rod 8 moves inward along the fixing groove 7, causing the protrusion 13 to disengage from the limiting position of the rotating rod 11. At this time, the scraper 5 will... The spring rotates outward, accumulating grease on the inner wall of the box 1. After the user stops pressing, the fixing rod 8 returns to its initial position under the action of the first compression spring. At this time, the user can rotate the scraper 5 back. When the scraper 5 rotates back, the protrusion 13 on the slide rod 9 will abut against the rotating rod 11 and cause the rotating rod 11 to rotate inward. When the scraper 5 returns to its initial position completely, the protrusion 13 can no longer restrict the rotating rod 11 from rotating outward. The rotating rod 11 will reset under the action of the tension spring and restrict the protrusion 13 from moving outward.
[0040] In this embodiment, the scraper 5 is provided with a shrinkage groove 15, and the slide rod 9 is disposed in the shrinkage groove 15 and slidably connected to the shrinkage groove 15. A second compression spring is provided in the shrinkage groove 15, one end of which abuts against the slide rod 9, and the other end of which abuts against the inner wall of the shrinkage groove 15 away from the slide rod 9. The end of the slide rod 9 away from the fixing rod 8 is arc-shaped. The inner wall of the slide groove 6 away from the fixing groove 7 is adapted to the shape of the slide rod 9.
[0041] Therefore, when the slide rod 9 rotates outward, it abuts against the inner wall of the end of the slide groove 6 away from the fixed groove 7, and moves into the contraction groove 15 under the action of this inner wall. When the scraper 5 rotates to the outside of the slide groove 6, the slide rod 9 will be completely retracted into the contraction groove 15. When the scraper 5 rotates back, when the scraper 5 returns to the range of the slide groove 6, the slide rod 9 will move outward from the contraction groove 15 and into the slide groove 6 under the action of the second compression spring, continuing to perform subsequent work in conjunction with the fixed rod 8. This reduces the length of the slide groove 6 and prevents grease from entering the slide groove 6.
[0042] In another embodiment, a positioning plate is provided on the inner wall of the box 1. The positioning plate is used for positioning the scraper 5 when it is reset. After the scraper 5 rotates to the initial position, it stops under the constraint of the positioning plate.
[0043] In another embodiment, two rotating sleeves 4 are provided, vertically evenly distributed on the rotating shaft 3. Two torsion springs are sleeved on the rotating shaft 3, and the two torsion springs are used to reset the two rotating sleeves 4 after rotation. The rotation directions of the two rotating sleeves 4 are opposite, and the remaining structures are set accordingly. Thus, the grease in the box 1 is simultaneously gathered within a certain range by the two scrapers 5, making it easy for the user to remove.
[0044] In another embodiment, a sealing ring is provided between the cover 2 and the body 1. This ensures the airtightness of the device and the purity of the lubricating grease.
[0045] The above description is only a preferred embodiment of the present utility model and not all embodiments. Anyone should know that structural changes made under the guidance of the present utility model are protected by the present utility model. All technical solutions that are the same as or similar to the present utility model are within the scope of protection of the present utility model.
