Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] Reference Figure 1-4 The utility model provides an embodiment: comprising a pressure measuring frame 1, a pressure block 2 is provided inside the pressure measuring frame 1, a pushing component 3 is provided inside the pressure measuring frame 1, a pressure plate 4 is fixedly installed at the bottom of the inner wall of the pressure measuring frame 1, a placement groove 5 is opened inside the pressure plate 4, and an ejection component 6 is provided inside the placement groove 5;
[0031] The ejection component 6 is used to eject the material on the top of the pressure plate 4, and the pushing component 3 is used to push the pressure block 2 to move to the top or bottom, so that the material can be pressurized. First, the material to be tested is placed on the top of the pressure plate 4, and then the pressure block 2 can be moved to the bottom through the ejection component 6. The movement of the pressure block 2 to the bottom can pressurize the material on the top of the pressure plate 4 for testing. When the material is pressurized, the pressurized material can be ejected through the ejection component 6.
[0032] Reference Figure 1-4 The pushing assembly 3 includes a rotating block 31, and the number of rotating blocks 31 is two. A placing plate 32 is provided inside the pressurized measuring frame 1. Connecting blocks 33 are fixedly installed on both sides of the top of the placing plate 32. The front side of the connecting block 33 is rotatably installed with a connecting rod 34 through an axle pin. The back of the connecting rod 34 is rotatably installed through the axle pin and the rotating block 31. The bottom of the placing plate 32 and the top of the pressurized block 2 are fixedly installed. Through the mutual cooperation of the rotating block 31, the placing plate 32, the connecting block 33 and the connecting rod 34, the pressurized block 2 can be driven to move toward the bottom when the placing plate 32 is pushed toward the bottom, thereby increasing the pressure. The pressure block 2 moves toward the bottom to pressurize the material on the top of the pressure plate 4, so that the material on the pressure plate 4 can be pressurized and tested. The interior of the pressure measuring frame 1 is provided with a positive and negative thread screw 35. The left end of the positive and negative thread screw 35 is rotatably installed through the bearing and the inner wall of the pressure measuring frame 1. The right end of the positive and negative thread screw 35 passes through the rotating block 31 and is threadedly installed with the rotating block 31. The right end of the positive and negative thread screw 35 is fixedly installed with a motor 36. The top of the motor 36 is fixedly installed with the top of the inner wall of the pressure measuring frame 1. Through the mutual cooperation of the positive and negative thread screw 35 and the motor 36, the When the motor 36 is turned, it can drive the forward and reverse screws 35 to rotate. The forward and reverse screws 35 rotate and drive the rotating block 31 to move inward. The rotating block 31 moves inward and drives the connecting rod 34 in the inclined state to gradually move inward. The connecting rod 34 moves inward and drives the placement plate 32 and the pressure block 2 to move toward the bottom. The pressure block 2 moves to the bottom to pressurize the material on the pressure plate 4. The limiting blocks 7 are fixedly installed on both sides of the placement plate 32. The limiting grooves 8 are provided on both sides of the pressure measuring frame 1. The limiting blocks 7 and the limiting grooves 8 are slidably installed. Through the mutual cooperation of the limiting blocks 7 and the limiting grooves 8, When the placement plate 32 moves toward the bottom, the limit block 7 can be driven to move toward the bottom, thereby limiting the placement plate 32 to prevent the placement plate 32 from getting stuck inside the main body when it moves. A stabilizing block 9 is fixedly installed on the top of the rotating block 31, and a stabilizing groove 10 is provided on the top of the inner wall of the pressure measuring frame 1. The stabilizing block 9 and the stabilizing groove 10 are slidably installed. Through the mutual cooperation between the stabilizing blocks 9 and the stabilizing blocks 9, the rotating block 31 can be limited to prevent the rotating block 31 from being affected by the positive and negative screws 35 and driving the rotating block 31 to rotate, thereby causing the rotating block 31 to be unable to move in a straight line.
[0033] Reference Figure 1-4The ejection assembly 6 includes an electric push rod 61, the telescopic end of the electric push rod 61 is fixedly installed with a connecting plate 62, and the top of the connecting plate 62 is fixedly installed with an ejection block 63, and the top of the ejection block 63 passes through the top of the pressure plate 4. Through the cooperation of the electric push rod 61, the connecting plate 62 and the ejection block 63, when the material on the pressure plate 4 is pressurized, the electric push rod 61 can be started, and the telescopic end of the electric push rod 61 drives the connecting plate 62 to move to the top, and the connecting plate 62 moves to the top to drive the ejection block 63 to move to the top. The ejection block 63 moves to the top to eject the material on the pressure plate 4. The front side of the pressure measuring frame 1 is provided with two sets of door panels 11, which are movably installed with the pressure measuring frame 1 through hinges. A handle 12 is fixedly installed on the front side of the door panel 11. Through the cooperation of the door panel 11 and the handle 12, the material can be placed on the pressure plate 4, and then the door body can be closed to prevent external impurities from entering the interior of the body, thereby causing the material to be dirty.
[0034] Working principle: First, place the material to be tested on the top of the pressure plate 4, and then start the motor 36. When the motor 36 is started, it can drive the forward and reverse screws 35 to rotate. The rotation of the forward and reverse screws 35 drives the rotating block 31 to move inward. The rotating block 31 moves inward and drives the connecting rod 34 in the inclined state to gradually move inward. The connecting rod 34 moves inward and drives the placement plate 32 and the pressure block 2 to move to the bottom. The pressure block 2 moves to the bottom to pressurize the material on the pressure plate 4. After the material on the pressure plate 4 is pressurized, the electric push rod 61 can be started at this time. The telescopic end of the electric push rod 61 drives the connecting plate 62 to move to the top. The connecting plate 62 moves to the top and drives the ejection block 63 to move to the top. The ejection block 63 moves to the top to eject the material on the pressure plate 4.
