DETAILED DESCRIPTION

[0028] In order to make the technical means, creation characteristics, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0029] As shown in Figures 1 to 7 A physical experiment is used sliding block type sliding speed experimental device, including base 1, the top of base 1 is fixedly connected with support rod 10 near the left side, the top of base 1 is fixedly connected with connecting plate 11 near the front and rear right side, the opposite surface of connecting plate 11 is rotatably connected with experimental mechanism 2, the top of support rod 10 is fixedly connected with reset mechanism 3;

[0030] Experimental mechanism 2 includes two guide frames 20, and the side far away from the right side of two guide frames 20 is rotatably connected to the inner side of connecting plate 11, and the middle of the left side of base 1 is rotatably connected with hydraulic cylinder 21, and the output end of hydraulic cylinder 21 is rotatably connected to the bottom of guide frame 20, and the front and rear sides of guide frame 20 are provided with limiting grooves 201, and the bottom of the inner side of guide frame 20 is fixedly connected with baffle 202 near the left side.

[0031] Reset mechanism 3 includes first servo motor 30, and the bottom of first servo motor 30 is fixedly connected to the top of support rod 10 near the left side, and the output end of first servo motor 30 is fixedly connected with threaded rod 31, and the outer surface of threaded rod 31 is threadedly connected with movable block 32, and the top of the inner side of movable block 32 is rotatably connected with connecting barrel 33, and the left and right sides of connecting barrel 33 are movably connected with push plate 34, and the side far away from the right side of push plate 34 is fixedly connected with limiting block 341, and the outer surface of limiting block 341 is movably connected to the inner side of limiting groove 201.

[0032] When the article needs to be tested, first, the article is placed to the right side of the inner side of guide frame 20, when the guide frame 20 is in a horizontal state, the first servo motor 30 is connected to the power supply, so that the first servo motor 30 drives the threaded rod 31 to rotate, the rotation of the threaded rod 31 drives the movable block 32 to move, after the movable block 32 moves, the article in the right position of the inner side of guide frame 20 is slid in guide frame 20 by the gravity of the article, so that the sliding test is carried out, after the article slides to the left side of guide frame 20, the article is blocked by baffle 202, so that the article is prevented from falling off from the left side of guide frame 20 after sliding to the left side.

[0033] As shown in Figure 2 The left side of the upper surface of support rod 10 is fixedly connected with limiting plate 12 near the front and rear, and the side far away from the right side of limiting plate 12 is overlapped on the top of guide frame 20.

[0034] When the hydraulic cylinder 21 drives the guide frame 20 to rotate counterclockwise, the left side of the top of the guide frame 20 is blocked by the limiting plate 12, so as to avoid that the left side of the guide frame 20 is higher than the right side.

[0035] As shown in Figure 5 and 6 , the front side of the movable block 32 close to the right side is fixedly connected with the second servo motor 36, the output end of the second servo motor 36 is fixedly connected with the second gear 37, the middle part of the connecting barrel 33 is fixedly connected with the first gear 35, and the outer ring of the second gear 37 is engaged with the outer ring of the first gear 35.

[0036] When two different objects need to be tested at the same time, the objects are placed on the right side of the top of the guide frame 20, the second servo motor 36 is powered on, the second servo motor 36 drives the second gear 37 to rotate, the second gear 37 drives the first gear 35 to rotate, the first gear 35 drives the connecting barrel 33 to rotate after rotating, the connecting barrel 33 drives the push plate 34 to rotate during rotating, so as to open the right side of the guide frame 20 and release the restriction on the movement of the objects, so that the objects on the right side can slide to the left side of the guide frame 20.

[0037] As shown in Figure 6 and 7 , the front and back sides of the inner side of the connecting barrel 33 are both slidingly connected with the tooth ring 38, the opposite sides of the tooth ring 38 are both fixedly connected with the spring 381, and the opposite sides of the spring 381 are fixedly connected to the inner side of the connecting barrel 33.

[0038] The rotation of the connecting barrel 33 is limited by the tooth ring 38, so that the push plate 34 can only rotate counterclockwise, which makes the push plate 34 rotate counterclockwise according to the angle of the rotation of the guide frame 20 when the guide frame 20 rotates, so that the bottom of the push plate 34 is always in contact with the top of the guide frame 20. If it is needed to make the push plate 34 rotate clockwise, the tooth ring 38 needs to be pushed to move into the connecting barrel 33, so as to release the restriction of the tooth ring 38 on the push plate 34. After the restriction of the push plate 34 is released, the push plate 34 can rotate freely, the tooth ring 38 is released after the bottom of the push plate 34 contacts the top of the guide frame 20, the spring 381 drives the tooth ring 38 to reset and then clamps into the side of the push plate 34 to restrict the rotation of the push plate 34 again.

[0039] As shown in Figure 7 , the opposite outer rings of the push plate 34 are both rotatably connected with the tooth blocks 342 distributed in a ring shape, and the opposite sides of the push plate 34 are both fixedly connected with the spring sheets 343.

[0040] When the activity restriction of the article is released during the test, the second servo motor 36 drives the connecting cylinder 33 to rotate clockwise, at this time, the rotation of the connecting cylinder 33 drives the gear ring 38 to rotate, since the tooth block 342 is restricted to only fit the inner ring of the gear ring 38 to rotate counterclockwise, and is reset again through the spring sheet 343 after rotation, when the connecting cylinder 33 rotates clockwise, the tooth block 342 and the push plate 34 are driven to rotate clockwise through the inner side of the texture, so that the push plate 34 opens the right side of the guide frame 20 to release the activity restriction of the article.

[0041] As shown in Figure 4 The first magnetic stone 203 is fixedly connected to the bottom of the guide frame 20 near the left and right sides.

[0042] The first magnetic stone 203 on the top of the guide frame 20 can always attract the push plate 34 to the top, and the first magnetic stone 203 is located near the front and rear positions on the inner side of the guide frame 20, which can effectively avoid affecting the sliding track and sliding speed of the test object.

[0043] As shown in Figure 7 The second magnetic stone 344 is fixedly connected to the bottom of the push plate 34 near the front and rear sides.

[0044] When the push plate 34 rotates counterclockwise each time, the second magnetic stone 344 on the bottom of the push plate 34 can always contact the top of the guide frame 20, so that the push plate 34 can better restrict the activity of the article and reset the article.

[0045] The working principle of the utility model is: when the article needs to be tested, the article is placed on the right side of the guide frame 20 and the right side of the push plate 34, the guide frame 20 is driven to rotate on one side of the connecting plate 11 through the extension of the hydraulic cylinder 21, and the guide frame 20 is inclined after rotation, so that the angle of the testing device for the article is adjusted, in this process, the push plate 34 rotates counterclockwise and contacts the top of the guide frame 20, at this time, the second servo motor 36 drives the push plate 34 to rotate, so as to release the restriction of the article, at this time, the article slides through the inclination of the guide frame 20, so that the sliding speed of the article is limited, then the gear ring 38 is pushed, the guide frame 20 is driven to rotate to the horizontal state through the hydraulic cylinder 21, in this process, the rotation of the guide frame 20 drives the push plate 34 to rotate clockwise, and when the gear ring 38 is released, the spring 381 drives it to reset and be clamped on the surface of the tooth block 342, the movable block 32 is driven to slide through the threaded rod 31, the push plate 34 is moved to the left side of the article, then the push plate 34 is driven to move through the threaded rod 31, when the push plate 34 moves, the article moves to the right side of the guide frame 20, so that the article is reset.

Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
