Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a concrete pressure detection device comprises a cylindrical shell 1, wherein one end of the cylindrical shell 1 is fixedly connected with a circular tube 2, and one side of the cylindrical shell 1 is provided with a groove 4; the push rod 3 penetrates through one end of the cylindrical shell 1, and is connected to one side of the cylindrical shell 1 in a sliding mode; and the pressure measuring device 5 is arranged in the cylindrical shell 1 and is used for detecting whether the pressure exceeds the standard or not after applying the pressure to the concrete. The elastic striking rod 8 in the pressure measuring device 5 is impacted towards the concrete by the cylindrical hammer 9 at one end of the pushing rod 3, and then whether the triggering button 15 can be touched after the elastic striking rod 9 is rebounded is combined.

Pressure measuring device 5 includes the first spring 6 of fixed connection in the inside one end of

cylindricality shell

1, 6 other end fixed connection knobs of

first spring

7, and 7 one side fixed connection elastic impact pole 8 of knobs, the elastic impact pole 8 other end can freely remove in 2 at the pipe, 7 opposite sides of knobs are equipped with

cylinder hammer

9, 9 fixed connection of cylinder hammer is in 3 one ends of catch bar, 9 one side fixed connection strip poles 10 of cylinder hammer, and 10 one end fixed connection elastic impact blocks 11 of strip pole, elastic impact blocks 11 are through strip pole 10 sliding connection in recess 4, elastic impact blocks 11 one side is equipped with early warning device 12 for the concrete pressure value that the warning detected has exceeded standard. After external force with the same size is applied to the push rod 3 at different concrete positions, the cylindrical hammer 9 pushes the elastic striking rod 8 to impact the concrete, the cylindrical hammer 9 is rebounded by reaction force, and the bar 10 on one side of the cylindrical hammer 9 drives the elastic striking block 11 to move in the groove 4.

Early warning device 12 includes the jingle bell 13 of fixed connection at 1 outer wall of cylindricality shell, telescopic link 14 is connected to 13 one end of jingle bell, 14 other end fixed connection trigger button 15 of telescopic link, 14 outsides of telescopic link are equipped with second spring 16, second spring 16 both ends difference fixed connection jingle bell 13 and trigger button 15. When the bullet piece 11 rebounds to the trigger button 15, the trigger button 15 triggers the bell 13 to make a sound, and when the bullet piece 11 presses the trigger button 15 backwards, the second spring 16 generates a reaction force on the trigger button 15, so that the trigger button 13 is prevented from being damaged by directly impacting, and the trigger button 15 is slowly reset at the same time.

And a piston 17 is arranged on one side of the cylindrical hammer 9, and the piston 17 is sleeved on the outer wall of the push rod 3. The position of the push rod 3 is stabilized through the piston 17, and the push rod 3 is prevented from shaking all around.
