Please refer to fig. 1 and 2, the utility model provides a cement mortar plain bumper's closing device, including plain bumper 100 and moulding-die 200, be equipped with two hinge columns 300 on plain bumper 100, the both sides of moulding-die 200 are articulated with two hinge columns 300 respectively, and the one end of keeping away from hinge column 300 of moulding-die 200 is equipped with holding rod 210, and the during operation is put test piece 1 on plain bumper 100, rotates holding rod 210 and lets moulding-die 200 push down test piece 1 and can begin work.

Specifically, all have the through-hole on two hinge columns 300, the through-hole is located the pin joint top, can insert in the through-hole and compress tightly strip 310, rotates at moulding-die 200 and pushes down the back, compresses tightly strip 310 through inserting, can block moulding-die 200 and upwards rotate, reaches and compresses tightly the effect.

In this embodiment, both ends of the pressing bar 310 are provided with insertion holes into which the T-shaped stopper bar 320 can be inserted. After the spacing strips 320 are inserted, the pressing strips 310 can be prevented from sliding off from the through holes under the conditions of shaking and the like, and the pressing die 200 can be pressed more stably. Further, the through hole is internally provided with an internal thread, the surface of the pressing strip 310 is provided with an external thread, and the pressing strip 310 can be fixed in the through hole through the threaded connection, so that the pressing die 200 is pressed at the current position more stably.

The side of the tapping platform 100 far away from the hinge post 300 is provided with a clamping device, the clamping device comprises two upright posts 400, a rotating rod 420 and a support post 410, the support post 410 is arranged between the two upright posts 400, and the support post 410 and the two upright posts 400 are positioned on the same straight line. One end of the rotating rod 420 is hinged to one of the upright columns 400, the other end of the rotating rod 420 is provided with a threaded through hole, the other pillar is also provided with a threaded through hole, and the rotating rod 420 can be in threaded connection with the threaded through hole through a threaded connecting piece.

The rotating rod 420 is further provided with a groove 430 adapted to the grip 210, and in this embodiment, the grip 210 is located in the middle of the pressing mold 200, so the groove 430 is also located in the middle of the rotating rod 420. The supporting column 410 is positioned corresponding to the holding rod 210, and the upper end of the supporting column 410 is also provided with a groove 430 corresponding to the holding rod 210. When moulding-die 200 pushed down to test piece 1 on, holding rod 210 fell to in the recess 430 of support column 410, rotated dwang 420, covered dwang 420 on holding rod 210, dwang 420 surrounded holding rod 210 with support column 410, the other end through the fixed dwang 420 of threaded connection spare, in this embodiment, threaded connection spare is bolt 440 to fix holding rod 210 at present position, reach and compress tightly the effect, make moulding-die 200 can not move about.

Further, one side of the pressing die 200 close to the jolt ramming table 100 is provided with a rubber pad, and the rubber pad can enable the pressing die 200 to be attached to the test piece 1 more closely, so that the test effect is better.

After long-term use, due to frequent friction and the like, a gap may occur between the pressing die 200 and the test piece 1, and after the gap becomes larger, the test piece 1 may not be pressed tightly, and the work is difficult. Therefore, the tapping platform 100 is further provided with a concave hole 110, the concave hole 110 is vertically formed, the bottom of the concave hole 110 is provided with a threaded column 120 along the axial direction, the hinge column 300 is inserted into the concave hole 110, the bottom of the hinge column 300 is provided with an internal threaded hole, and the hinge column 300 is in threaded connection with the threaded column 120. After the gap occurs, the pressing die 200 can be detached from the hinge post 300, the hinge post 300 is rotated downward by one turn to lower the height, and then the pressing die 200 is mounted to work again, so that the device is not scrapped, the service life of the device can be prolonged, and the cost is reduced.

The working principle of the pressing device of the cement mortar jolt ramming table is as follows: the test piece 1 is placed on the jolt ramming table 100, the holding rod 210 is held to press the pressing die 200 downwards, after the test piece 1 is pressed, the holding rod 210 falls on the supporting column 410, the holding rod 210 is covered by rotating the rotating rod 420, and the other end of the rotating rod 420 is fixed on the upright column 400 through a threaded connection piece. The pressing strip 310 is screwed into the through hole, the limiting strip 320 is inserted, the pressing strip 310 is stabilized, and therefore both sides of the pressing die 200 are fixedly pressed. After a long period of use, with a gap, the die 200 is removed, the hinge post 300 is rotated downward to a reduced height, and the die 200 is installed for further use.

Use above-mentioned cement mortar plain bumper, install additional through simple structure, just can consolidate the moulding-die from both sides, make the moulding-die can keep compressing tightly the test piece, the performance that compresses tightly is good for the test data that arrives is more accurate, improves work efficiency. And after a gap appears in long-term use, the device can be adjusted to be continuously used, the service life of the device is prolonged, and the cost is saved.
