[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3 The utility model provides an embodiment: a detection structure of a metal powder loose density tester, including a base 1, the outer wall of the base 1 is slidably connected to a slide seat 2 symmetrical up and down, an adjustment component is arranged inside the slide seat 2, a measuring cylinder 5 is fixedly connected to the outer wall of the lower slide seat 2, a material control cylinder 6 is fixedly connected to the outer wall of the upper slide seat 2, the outer wall of the material control cylinder 6 is slidably connected to the inside of the measuring cylinder 5, a feed hopper 7 is fixedly connected to the inside of the material control cylinder 6, a rotating shaft 8 is rotatably connected to the inside of the material control cylinder 6, one end of the rotating shaft 8 is fixedly connected to a rotating handle 9, and the other end of the rotating shaft 8 is fixedly connected to A main bevel gear 10 is connected, and a connecting plate 11 is rotatably connected to the outer wall of the rotating shaft 8, and a screw rod 13 is rotatably connected to the inside of the connecting plate 11, and one end of the screw rod 13 is fixedly connected to the auxiliary bevel gear 12, and the main bevel gear 10 is meshed with the auxiliary bevel gear 12, and the other end of the screw rod 13 is rotatably connected to the fixed plate 14, and a movable ring 15 is threadedly connected to the outer wall of the screw rod 13, and a baffle 16 is fixedly connected to the outer wall of the movable ring 15; the adjustment assembly includes an adjusting bolt 3, and the outer wall of the adjusting bolt 3 is threadedly connected to the inside of the sliding seat 2, and the outer wall of the adjusting bolt 3 is fixedly connected to the first knob 4;

[0025] Specifically, when it is necessary to accurately control the amount of metal powder released, the main bevel gear 10 is driven to rotate by turning the handle 9. Since the main bevel gear 10 and the secondary bevel gear 12 are meshed with each other, the rotation of the main bevel gear 10 will also drive the secondary bevel gear 12 to rotate together, which enables the movable ring 15 to slide on the outer wall of the screw rod 13. The sliding operation of the movable ring 15 will cause the baffle 16 to slide inside the measuring cylinder 5, and then adjust the distance between the baffle 16 and the fixed plate 14, so as to achieve accurate control of the amount of metal powder released. By adjusting the position of the movable ring 15, the distance between the baffle 16 and the fixed plate 14 can be accurately controlled as needed, thereby controlling the amount of metal powder released. This not only improves the control accuracy of the metal powder amount, but also improves the convenience and practicality of operation. At the same time, it also makes the measuring instrument have a wider application in the metal powder measurement and processing process, and can effectively improve production efficiency and product quality.

[0026] Reference Figure 1 , Figure 2 and Figure 4, a scraper 17 is slidably connected to the inside of the measuring cylinder 5, and a handle 18 is fixedly connected to the outer wall of the scraper 17; a mounting plate 19 is fixedly connected to the outer wall of the measuring cylinder 5, and a fixing bolt 20 is threadedly connected to the inside of the mounting plate 19; a second knob 21 is fixedly connected to one end of the fixing bolt 20; a fixing sleeve 22 is fixedly connected to the outer wall of the measuring cylinder 5, and the outer wall of the fixing bolt 20 is threadedly connected to the inside of the fixing sleeve 22; a top plate 23 is slidably connected to the inside of the fixing sleeve 22, and the inner wall of the top plate 23 is threadedly connected to the outer wall of the fixing bolt 20; a fixing spring 24 is sleeved on the outer wall of the fixing bolt 20, one end of the fixing spring 24 is fixedly connected to the outer wall of the top plate 23, and the other end of the fixing spring 24 is fixedly connected to the inside of the fixing sleeve 22;

[0027] Specifically, when the scraper 17 needs to be firmly fixed, by pushing the handle 18, the scraper 17 can close the control barrel 6, thereby ensuring that the powder will not overflow or be contaminated during operation. At the same time, turning the second knob 21 will drive the fixing bolt 20 to rotate inside the fixing sleeve 22, so that the fixing bolt 20 can be fixed inside the fixing sleeve 22, and through the rotation of the fixing bolt 20, the top plate 23 can compress the fixing spring 24. When the fixing spring 24 is compressed, its rebound force will make the fixing bolt 20 more firmly fixed inside the fixing sleeve 22, so that the powder can be scraped flat, and at the same time, the scraper 17 can be firmly fixed, which improves the convenience and operating efficiency of the measuring instrument, allowing users to easily measure and process powder, thereby improving production efficiency and product quality.

[0028] Working principle: When the amount of metal powder needs to be controlled, the main bevel gear 10 can be driven to rotate by the rotating shaft 8 by turning the rotary handle 9. Since the main bevel gear 10 and the auxiliary bevel gear 12 are meshed with each other, the main bevel gear 10 can drive the auxiliary bevel gear 12 to rotate together, thereby driving the movable ring 15 to slide on the outer wall of the screw rod 13, so that the movable ring 15 can drive the baffle 16 to slide inside the measuring cylinder 5, and then continuously adjust the distance between the baffle plate 14, so as to achieve the effect of controlling the amount of powder released, thereby improving the practicality of the measuring instrument. The utility model has the advantages that when the scraper 17 needs to be firmly fixed, the scraper 17 can be driven to close the material control barrel 6 by pushing the handle 18, and the second knob 21 is turned to drive the fixing bolt 20 to rotate inside the fixing sleeve 22, and the fixing bolt 20 can also drive the top plate 23 to compress the fixing spring 24, and then the rebound of the fixing spring 24 can make the fixing bolt 20 better fixed inside the fixing sleeve 22, so as to achieve the effect of scraping the powder flat, and at the same time facilitate the effect of fixing the scraper 17, thereby improving the convenience of the measuring instrument.
