Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses an upper plate 2 and hypoplastron 3 through four stand 1 fixations, the fixed surface of hypoplastron 3 has pressure-bearing platform 4, threaded connection has screw rod 5 on the upper plate 2, the lower extreme rigid coupling of screw rod 5 has clamp plate 6, the inside of stand 1 is equipped with standing groove 7, the upper and lower both ends of standing groove 7 are rotated and are connected with winding up roller 8, winding up roller 8's pivot department is equipped with the torsional spring, winding up roller's surface rigid coupling has guard plate 9, and guard plate 9 rolls up on winding up roller 8 when the winding up roller rotates, logical groove 12 that supplies guard plate 9 to pass is seted up to one side of stand 1, the terminal surface rigid coupling of guard plate 9 has link 10, stand 1's side rigid coupling has couple 11, and couple 11 catches on link 10.

When a pressure test is required, firstly, the protection plate 9 is pulled to extend outwards from the through groove 12 until the hanging ring 10 is close to the hanging hook 11 on the other upright post 1, and the hanging ring 10 is hooked by the hanging hook 11 to fix the protection plate 9, so that the periphery can be protected, and splashed fragments are prevented from hurting people; be equipped with the torsional spring on the winding up roller 8, the torsional spring makes winding up roller 8 be in a state of winding protection plate 9 on the winding up roller all the time, like this when not using, protection plate 9 can be rolled up by winding up roller 8 automatically, conveniently like this, it has experimental concrete piece or takes out the concrete piece of accomplishing to place the concrete piece again after experimental completion, and its link 10 still is in the outside after protection plate 9 is being completely rolled up, only need stimulate link 10 can take out protection plate 9 when needs stimulate protection plate 9 like this, facilitate the use.

Furthermore, soft cleaning bristles 13 are arranged on the inner wall of the through groove 12, and the soft cleaning bristles 13 are respectively abutted against two sides of the protection plate 9. Thus, when the protection plate 9 is retracted, the surface thereof is left with debris by blocking the scattering of the debris, so that the debris can be swept out by the soft cleaning bristles 13 to prevent the debris from being rolled up on the protection plate 9.
