Technical Field

The invention relates to the technical field of real estate evaluation, in particular to a hollowing detector for real estate evaluation.

Background

The hollowing is caused by the air existing in the original masonry and the dust layer, during detection, a clattering-clattering sound is generated by tapping the plastering layer and the leveling layer with an empty drum hammer or a hard object, so that the hollowing is the hollowing phenomenon in the house quality, which generally refers to the phenomenon that the hollowing occurs between the floor, the wall surface, the ceiling decoration layer and the structural layer of the house due to the fact that the floor, the wall surface, the ceiling decoration layer and the structural layer are not firmly adhered and combined, and the empty drum is commonly called as 'two layers of leather'.

Need use hollowing detection device after the tile is spread and is pasted, but current hollowing detects and mostly is the artifical detection of knocking, and long-time measuring lets the user produce fatigue easily to cause the phenomenon of inconvenient detection, the inconvenient user is spread the condition of pasting to the tile and is detected, has reduced detection device's practicality.

Disclosure of Invention

It is an object of the present invention to provide a hollowing detector for real estate evaluations in order to address the above-mentioned problems.

In order to solve the above problems, the present invention provides a technical solution: a hollowing detector for real estate assessment comprises a housing, a moving wheel, a handle, a sliding rail, a lifting plate, a vertical rod, a spring, a knocking block, a connecting column, a knocking head, an installation rod, a motor, a cam and a belt; a plurality of movable wheels are connected around the lower surface of the housing; the top end of the cover shell is fixedly connected with a handle; two sides inside the housing cavity are fixedly connected with upright posts; the walls of two side chambers inside the housing chamber are fixedly connected with sliding rails; the lifting plate is connected to the vertical rod in a sliding mode, and two ends of the lifting plate are connected to the sliding rails in a sliding mode; the outer surface of the lower end of the vertical rod is connected with a spring in a covering mode; the center of the top end of the lifting plate is fixedly connected with a knocking block; the center of the bottom end of the lifting plate is fixedly connected with a knocking head through a connecting column; the top end in the housing cavity is fixedly connected with an installation rod and a motor; the tail end of the mounting rod is movably connected with a cam; the output end of the motor is connected with the input end of the cam through a belt.

Preferably, the motor is a variable frequency motor.

Preferably, the spring is a disc spring.

The invention has the beneficial effects that: the invention has the advantages of reasonable and simple structure, low production cost, convenient installation and complete functions, and the motor drives the cam to rotate to knock the knocking block by moving the movable wheel, and the knocking head reciprocates up and down under the action of the spring, thereby detecting the hollowing.
