Technical Field

[0001] The utility model relates to a detector, and more specifically to a concrete strength detector for concrete structures. Background Art

[0002] Concrete is a building material, which is formed by mixing water, sand, and stone aggregates in a certain proportion and then stirred to form concrete. It is mainly used in the field of civil engineering. At the same time, the raw materials of concrete are relatively inexpensive, and it has the characteristics of high compressive strength, durability, and a wide range of strength grades.

[0003] Traditional methods for detecting the strength of concrete include the rebound method, ultrasonic method, drilling method, etc. However, the first two generally require connecting the equipment to a reading instrument, and the user needs to hold the reader, while another user contacts the equipment with the concrete for detection. Among them, the rebound method requires the user to select and mark a grid on the concrete surface with a measuring scale and a pen, and then detect the grade according to the relevant process with a rebound instrument, which is inefficient and troublesome. Summary of the Utility Model

[0004] The main technical problem to be solved by the utility model is to provide a concrete strength detector for concrete structures, which can solve the above-mentioned problems.

A segmented plate is fixedly connected inside the housing. A detection display instrument, a storage mechanism, a wire, an ultrasonic display instrument, and a rebound instrument are arranged inside the segmented plate. The detection display instrument is signal-connected to the ultrasonic display instrument and the rebound instrument through the wire. The wire is arranged inside the storage mechanism. A grid mechanism is fixedly connected to the front surface of the housing.

[0006] Furthermore, the storage mechanism includes a winding roller, a torsion spring, a guide, a gear, a loop wheel, and an airbag. The winding roller is rotatably connected to the inner wall of the segmented plate. The torsion spring is fixedly connected to the outer side wall of the winding roller, and the other end of the torsion spring is fixedly connected to the segmented plate. A guide hole is formed on the rear surface of the housing. The gear is fixedly connected to the outer side wall of the winding roller. The loop wheel is rotatably connected to the inner wall of the segmented plate. The loop wheel is meshed with the gear. The airbag is arranged on the inner wall of the segmented plate. The airbag is fixedly connected to the loop wheel. The guide is slidably connected inside the guide hole. The other end of the airbag is fixedly connected to the guide. The wire is wound around the outer side wall of the winding roller.

[0007] Further, the grid mechanism includes a telescopic rod, a telescopic hole, a seal, and a flip mud. The telescopic hole is formed on the rear surface of the housing. The flip mud is rotatably connected inside the telescopic hole. The telescopic rod is fixedly connected inside the telescopic hole. The top end of the telescopic rod is fixedly connected with the seal.

[0008] Further, a buckle is provided on the upper surface of the segmented plate.

[0009] Further, a shell plate is rotatably connected to the upper surface of the housing.

[0010] Further, a fixing belt is fixedly connected to the front surface of the housing.

[0011] The beneficial effects of the concrete strength detector for concrete structures of the present utility model are as follows:

[0012] The housing is provided for holding the detection display instrument, corresponding wires, ultrasonic display instrument, and rebound instrument. The rebound instrument and ultrasonic display instrument are in contact with the concrete to be detected, and then the values are read through the detection display instrument.
