The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

Referring to fig. 1-4, the magnet compression testing device comprises a testing machine body 1, wherein a testing mechanism 2 is slidably connected to the inner side of the testing machine body 1, symmetrically arranged connecting plates 4 are connected to two sides of the testing mechanism 2, two fixing bolts 9 are slidably connected to the connecting plates 4, the fixing bolts 9 penetrate through the connecting plates 4 to be in threaded connection with the testing mechanism 2, and shielding plates 5 are connected to the bottom ends of the connecting plates 4.

According to the magnet compression-resistant testing device, when the testing device is installed, the connecting plate 4 is tightly attached to the testing mechanism 2, then the connecting plate 4 and the testing mechanism 2 are fixedly connected together through the fixing bolts 9, the shielding plate 5 is connected with the bottom ends of the connecting plate 4, so that the shielding plate 5 is positioned at the lower ends of two sides of the testing mechanism 2, the testing mechanism 2 is started to move downwards together with the connecting plate 4 and the shielding plate 5, when the testing mechanism 2 is contacted with a test piece, the shielding plate 5 is positioned at two sides of the test piece, even if part of fragments on the test piece are bounced out, the shielding plate 5 can intercept the fragments, so that injury to workers is avoided.

As shown in fig. 1, 2 and 3, two groups of symmetrically arranged sliding grooves 3 are formed in two sides of the inner wall of the main body 1 of the testing machine, the sliding grooves 3 are matched with the connecting plate 4 and the shielding plate 5, and the sliding grooves 3 are in T-shaped arrangement. Limiting the connecting plate 4 and the shielding plate 5 through the sliding chute 3 prevents gaps from being generated between the connecting plate 4 and the shielding plate 5 and the testing machine main body 1, so that the effect of shielding scraps is influenced.

As shown in fig. 2 and 4, the lower end of the inside of the shielding plate 5 is slidably connected with a first extension plate 6, and the lower end of the inside of the first extension plate 6 is slidably connected with a second extension plate 7. When the height of test piece is higher, first extension board 6 and second extension board 7 can slide out under the effect of gravity to protect the both sides of test piece, avoid having the piece to splash everywhere to hit the workman, if test mechanism 2 when moving down, the bottom of second extension board 7 has contacted with the inner wall of test machine main part 1, then when test mechanism 2 continues to move down, second extension board 7 can slide in first extension board 6 under the effect of pressure, so can guarantee the interception efficiency to the piece, can avoid second extension board 7 to be extruded again and take place the damage.

As shown in fig. 4, a positioning bolt 8 is slidably connected to one side of the shielding plate 5 away from the testing mechanism 2, and the positioning bolt 8 penetrates through the shielding plate 5 and the side wall of the first extension plate 6 to abut against the second extension plate 7. When the shielding plate 5 needs to be replaced, the first extending plate 6 and the second extending plate 7 can be sequentially retracted into the shielding plate 5, and then the positioning bolts 8 are screwed down, so that the positioning bolts 8 are abutted against the side walls of the second extending plate 7, and the first extending plate 6 and the second extending plate 7 can be prevented from sliding downwards, so that workers can conveniently detach and replace the shielding plate 5 and the connecting plate 4.

As shown in fig. 1 and 2, the thickness of the shielding plate 5 is smaller than the thickness of the chute 3, and the thickness of the shielding plate 5 is greater than three-quarters of the thickness of the chute 3. The thickness can ensure that the shielding plate 5 can smoothly slide in the chute 3, and can also ensure that a gap between the shielding plate 5 and the chute 3 is smaller, so that the shielding plate 5 is not easy to shake.
