[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Please see Figure 1-7 This utility model provides a technical solution: an automatic sand filling device for barbell plates, including a base plate 1, with hydraulic rods 3 fixedly connected to both sides of the base plate 1, and a sand filling device 2 fixedly connected to the end of the two hydraulic rods 3 away from the base plate 1.

[0027] A first fixing plate 9 is fixedly connected to the base plate 1. An annular groove 13 is provided on the first fixing plate 9. A semi-threaded rod 5 is slidably connected to both sides inside the annular groove 13. A barbell plate 4 is movably sleeved on the upper surface of the semi-threaded rod 5. A sand injection hole 11 is provided on the barbell plate 4. A one-way valve 12 is fixedly connected inside the sand injection hole 11. A nut 7 is threadedly connected to the semi-threaded rod 5.

[0028] When the barbell plate 4 is fixedly installed on the first fixed plate 9 with the sand injection hole 11 facing upwards via the semi-threaded rod 5, the sand injection hole 11 corresponds exactly to the sand outlet hole of the sand filling device 2. When the hydraulic rod 3 is lowered by the external drive mechanism, the sand filling device 2 moves downward, and the discharge pipe of the sand filling device 2 enters the interior of the sand injection hole 11. The discharge pipe then squeezes the one-way valve 12, thereby opening the sand injection hole 11 and opening the valve on the sand filling device 2 to inject sand into the barbell plate 4. After the sand injection is completed, the one-way valve 12 will close the sand injection hole 11, so that the barbell plate 4 will not leak sand due to rotation.

[0029] One end of the semi-threaded rod 5 is fixedly connected to a large gear 20, which is rotatably connected to one side of the first fixed plate 9. The bottom of the sand filling device 2 is fixedly connected to a lifting plate 17, which has a first sliding groove 26. A first sliding rod 27 is slidably connected inside the first sliding groove 26. A rack 18 is fixedly connected to one end of the first sliding rod 27 away from the first sliding groove 26. A first telescopic spring 28 is movably sleeved on the upper surface of the first sliding rod 27. The two ends of the first telescopic spring 28 are fixedly connected to the rack 18 and the opposite side of the lifting plate 17, respectively.

[0030] The first fixed plate 9 has a diamond-shaped groove 19, and the rack 18 is slidably connected inside the diamond-shaped groove 19.

[0031] The two protruding corners of the rhomboid groove 19 are each provided with a third sliding groove 30. The interior of each of the two third sliding grooves 30 is fixedly connected with a second telescopic spring 29. The end of each of the two second telescopic springs 29 away from the two third sliding grooves 30 is fixedly connected with a slider 25.

[0032] A second fixing plate 10 is fixedly connected to the base plate 1. A torsion spring 23 is fixedly connected to the second fixing plate 10. The end of the torsion spring 23 away from the second fixing plate 10 is fixedly connected to the large gear 20.

[0033] In the initial position, hydraulic rod 3 is in a raised state, and rack 18 is on the outside of diamond groove 19. When hydraulic rod 3 is activated, it begins to descend, thereby driving lifting plate 17 to move downwards. Simultaneously, rack 18 slides inside diamond groove 19. When rack 18 moves to the bottom of diamond groove 19, it squeezes slider 25. The second telescopic spring 29 inside the slides pushes slider 25 into the third sliding groove 30. After sand injection is completed, hydraulic rod 3 drives sand injection device 2 to rise. Due to the setting of the second telescopic spring 29, slider 25 is reset. At this time, rack 18 slides to the inside of diamond groove 19. At this time, rack 18 and large gear 20... The meshing mechanism drives the large gear 20 to rotate 180 degrees, causing the torsion spring 23 to deform. This deformation, via the semi-threaded rod 5 on the large gear 20, causes the barbell plate 4 to slide inside the annular groove 13. After the rack 18 disengages, the torsion spring 23 on the back of the large gear 20 can reset the barbell plate 4. The rotation of the barbell plate 4 facilitates inspection by workers to check its quality and for any sand leakage. The raising and lowering of the hydraulic rod 3 allows the sand injection and inspection of the barbell plate 4 to be completed in one operation, saving time, increasing efficiency, and significantly increasing production capacity. It also facilitates direct inspection of the barbell plate 4's quality.

[0034] A rotating rod 21 is fixedly connected to the first fixed plate 9. A small gear 24 is rotatably connected to the rotating rod 21. The small gear 24 meshes with the large gear 20. A push block 22 is fixedly connected to the small gear 24.

[0035] A sliding groove 8 is provided on the first fixed plate 9. A second sliding groove 14 is provided inside the sliding groove 8. A second sliding rod 15 is slidably connected inside the second sliding groove 14. A knocking rod 6 is fixedly connected to one end of the second sliding rod 15 away from the second sliding groove 14. The knocking rod 6 is slidably connected inside the sliding groove 8. A third telescopic spring 16 is movably sleeved on the upper surface of the second sliding rod 15. The two ends of the third telescopic spring 16 are fixedly connected to the sliding groove 8 and the knocking rod 6 on opposite sides, respectively.

[0036] When the hydraulic rod 3 rises and drives the large gear 20 to rotate, the large gear 20 drives the small gear 24 to rotate, which in turn drives the push block 22 on the small gear 24 to rotate. Through the rotation of the push block 22, the knocking rod 6 is pushed to slide into the second sliding groove 14. The knocking rod 6 is reset by the third telescopic spring 16 on the second sliding rod 15, so as to knock the barbell plate 4. This prevents the defective product from going undetected when the holes on the barbell plate 4 are blocked by sand. By knocking the blocked holes of the barbell plate 4, the defective products of the barbell plate 4 can be better detected, making it easier for staff to find defective products.

[0037] Working principle:

[0038] When the barbell plate 4 is fixedly mounted on the first fixed plate 9 with the sand injection hole 11 facing upwards via the semi-threaded rod 5, the sand injection hole 11 corresponds exactly to the sand outlet hole of the sand filling device 2. When the hydraulic rod 3 is lowered by the external drive mechanism, the sand filling device 2 moves downwards, allowing the discharge pipe of the sand filling device 2 to enter the interior of the sand injection hole 11. This discharge pipe then squeezes the one-way valve 12, opening the sand injection hole 11 and consequently opening the valve on the sand filling device 2, allowing sand to be injected into the barbell plate 4. After sand injection is completed, the one-way valve 12 will close the sand injection hole 11 to prevent sand leakage from the barbell plate 4 due to rotation. In the initial position, the hydraulic rod 3 is in the raised state, and the rack 18 is on the outside of the diamond groove 19. When the hydraulic rod 3 is activated, it begins to descend, thereby driving the lifting plate 17 to move downward, and simultaneously driving the rack 18 to slide inside the diamond groove 19. When the rack 18 moves to the bottom of the diamond groove 19, it will squeeze the slider 25, and through the internal second telescopic spring 29, it will... When the slider 25 is pressed into the third sliding groove 30, after sand injection is completed, the hydraulic rod 3 drives the sand injection device 2 to rise. Due to the setting of the second telescopic spring 29, the slider 25 will be reset. At this time, the rack 18 will slide to the inside of the diamond groove 19. At this time, the rack 18 and the large gear 20 mesh, driving the large gear 20 to rotate 180 degrees, causing the torsion spring 23 to deform. Through the semi-threaded rod 5 on the large gear 20, the barbell plate 4 will slide inside the annular groove 13. After the rack 18 disengages, the torsion spring 23 on the back of the large gear 20 can drive the barbell plate 4 to reset. When the hydraulic rod 3 rises and drives the large gear 20 to rotate, the large gear 20 will drive the small gear 24 to rotate, thereby driving the push block 22 on the small gear 24 to rotate. Through the rotation of the push block 22, the knocking rod 6 is pushed to slide into the second sliding groove 14. Through the third telescopic spring 16 on the second sliding rod 15, the knocking rod 6 is reset, realizing the knocking of the barbell plate 4.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
