Description

Technical Field

[0001] The utility model relates to the technical field of rebound hammers, in particular to a portable rebound hammer. Background Art

[0002] The basic principle of the rebound hammer is to use a spring to drive a heavy hammer. The heavy hammer hits the impact rod in vertical contact with the concrete surface with constant kinetic energy, causing the local concrete to deform and absorb part of the energy, and the other part of the energy is converted into the rebound kinetic energy of the heavy hammer. When the rebound kinetic energy is completely converted into potential energy, the heavy hammer rebounds to the maximum distance. The instrument displays the maximum rebound distance of the heavy hammer in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring).

[0003] A Chinese patent discloses a portable rebound tester (authorization announcement number CN216051063U). The patented technology includes a rebound tester housing, a rebound tester host, a striking rod, and a driving assembly. The rebound tester host is installed on the rebound tester housing through a connecting assembly, and the striking rod and the driving assembly are installed inside the rebound tester housing. The driving assembly includes an electromagnetic driver, a photoelectric sensor, and a strip grating. The photoelectric sensor and the strip grating are respectively arranged on both sides of the striking rod and installed on the inner wall of the rebound tester housing. The driving end of the electromagnetic driver is driven and connected to the striking rod. A threaded cap is provided at one end of the rebound tester housing near the striking rod, and a gasket is provided on the inner wall of the threaded cap away from the end of the rebound tester housing and is sleeved on the striking rod; a controller and a battery are provided inside the rebound tester host, and a display screen and an operation panel are installed on the rebound tester host. The operation panel controls the connection to the controller, and the controller controls the connection to the display screen, the electromagnetic driver, the photoelectric sensor, and the strip grating. The photoelectric sensor is connected to the controller wirelessly for data exchange.

[0004] However, there are still some shortcomings in this patent. Although the rebound hammer in this patent can exchange data, it can be seen from the drawings of this patent that this patent needs to be taken manually when in use, which not only increases the labor intensity of the staff, but also affects its efficiency in detecting concrete. Therefore, those skilled in the art provide a portable rebound hammer to solve the problems raised in the above background technology. Utility Model Content
