[CN 201811067516.2] Concrete press for bidirectionally inflating concrete baffle by hand


[CN 201811067516.2] A concrete press that inflates the concrete baffle in both directions by hand. Title: A concrete press that inflates the concrete baffle in both directions by hand. Application number: CN 201811067516.2 Applicant: Chen Xiang Application date: 2018-9-13 Patent type: Invention application The present invention discloses a concrete press that inflates the concrete baffle in both directions by hand, the structure includes a controller, a handwheel disc, a body, a column, a screw rod, an upper pressing block, a concrete splash-proof device, and a support table. One side of the body is connected with a controller, and the top surface of the body is provided with a handwheel disc. The center of the bottom surface is vertically connected with the top of the screw rod. Compared with the prior art, the present invention has the beneficial effect that the lighter foam board can be extended to the back box by pneumatic force around the lower pressing block, using a light transparent thin plate to replace multiple small holes for observation can not only block dust, but also effectively block concrete, prevent sand and other fine substances from entering the eyes, prevent concrete from splashing everywhere, and at the same time make the concrete stay in the lower pressure block, further improve the safety of the operator during detection. At the same time, the hinge plate on the lower pressure block can be pushed up after detection, thus quickly cleaning the cracked concrete.
