Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be known from fig. 1 to 7, a concrete compression testing machine comprises a main machine 1, a hydraulic machine 2 is arranged at the bottom of one side of the main machine 1, a lower pressing plate 3 is arranged above the hydraulic machine 2 in a telescopic mode, a top plate 4 is fixed above the hydraulic machine 2, a lead screw 5 is connected to the top plate 4 in a threaded mode, an upper pressing plate 6 is fixed at the lower end of the lead screw 5, a sleeve plate 7 is arranged on the outer side of the upper pressing plate 6, a sleeve hole 8 matched with the upper pressing plate 6 is formed in the middle of the sleeve plate 7, a limiting ring 9 is arranged at the lower end of the sleeve hole 8, a clamping ring 10 is arranged below the limiting ring 9, a sliding box 11 is arranged on the lower pressing plate 3 in a sliding mode, the sliding box 11 comprises a lower layer 12 matched with the lower pressing plate 3, an upper layer 13 is arranged above the lower layer 12, a lantern ring 14 matched with the clamping ring 10 is arranged above the upper layer 13, and the lantern ring 14 is arranged on the upper layer 13 in a telescopic mode.

When the utility model is used, the air conditioner is provided with a fan,

fix lagging 7 on top board 6, smooth case 11 slides and places on holding down plate 3, place the concrete test piece in upper 13, rotate lead screw 5, make top board 6 drive lagging 7 move down, with lantern ring 14 card make lantern ring 14 and snap ring 10 cooperation in the outside of snap ring 10, protect the concrete test piece between upper 13 and lagging 7 completely, starting equipment tests this moment, the piece that the concrete test piece collapses garrulous can be collected at upper 13 insidely, take smooth case 11 out after experimental the completion and clear up can, unusual convenience, can not cause the influence to operational environment.

In order to fix the sleeve plate 7 on the upper pressing plate 6 conveniently, a plurality of limiting rods 15 located at the edge of the sleeve hole 8 are arranged above the sleeve plate 7 in a rotating mode, the sleeve plate 7 is sleeved from the lower direction of the upper pressing plate 6, the limiting rods 15 are used for fixing the upper portion of the sleeve plate 7, and the sleeve plate 7 is fixed to the outer portion of the upper pressing plate 6.
