[0002] The concrete rebound test hammer is a non-destructive testing tool used to evaluate the strength of concrete. It is also suitable for testing the strength of general building components, bridges, and various other components. It infers the strength level of concrete by measuring the degree of rebound after the concrete surface is impacted. The concrete rebound test hammer usually consists of a striker and a measuring device.

It is also inconvenient to move the equipment or fix or place the equipment to perform strength testing, which affects work efficiency to a certain extent. Therefore, we propose a concrete rebound testing device. Utility Model Content

[0007] Through the above technical solution, the spring is the main buffering method for the slide rod. When the equipment is tested on the concrete wall, it will not affect the firing pin and the rebound cylinder, making the value more accurate.

[0008] Furthermore, an outer wall of one end of the sliding rod away from the fixing ring is fixedly connected to a positioning ring, and an outer wall of the positioning ring is fixedly connected to a positioning block.

[0009] Through the above technical solution, the positioning block can mainly assist in aligning the horizontal line during positioning.

[0010] Furthermore, a buffer pad is fixedly connected to the outer wall of one end of the positioning block away from the sliding rod, and a fixing sleeve is fixedly connected to the outer wall of the rebound cylinder.

[0011] Through the above technical solution, the buffer pad can first provide a certain buffer when the equipment directly contacts the concrete wall.

[0012] Furthermore, the inner wall of the fixing ring is fixedly connected to a plurality of fixing rods, the outer wall of the rebound cylinder is fixedly connected to a second fixing sleeve, and the outer wall of the fixing pad is fixedly connected to a rotating shaft seat.

[0013] Through the above technical solution, the fixing sleeve 2 and the fixing sleeve can make the fixing ring more secure and less likely to cause equipment damage.

[0014] Furthermore, the inner wall of the rotating shaft seat is rotatably connected to a bent rod, and the inner wall of one end of the bent rod away from the rotating shaft seat is rotatably connected to a rotating rod.

[0015] Through the above technical solution, the handle can be freely rotated on the crank by utilizing the rotating rod to switch the functions.

[0016] Furthermore, the outer wall of the rotating rod is fixedly connected to a handle, the outer wall of the fixing seat is fixedly connected to a fixing block, and the outer wall of the fixing block is fixedly connected to a connecting block.

[0018] Furthermore, a hand push handle is fixedly connected to the inner wall of the connecting block, and a fixing rod 2 is fixedly connected to the outer wall of the hand push handle away from one end of the connecting block.

[0019] Through the above technical solution, the fixing rod can fix the push handle and the fixing seat, thereby enhancing the firmness of the equipment.

[0020] Furthermore, the outer wall of the second fixing rod away from the end of the push handle is fixedly connected to the second fixing block, and the top outer wall of the second fixing block is fixedly connected to the fixing seat.

[0021] Through the above technical solution, the fixing block can make the push handle more solid and will not be damaged due to excessive force when pushing the push handle.

[0022] The utility model has the following beneficial effects:

[0023] 1. The utility model is provided with a positioning ring. First, by holding the hand handle and the hand push handle, the device is aimed at the concrete wall, and the position to be tested is confirmed. The buffer pad and the positioning ring are aligned with the wall. The positioning block is used to assist in confirming the horizontal positioning of the device. Then the hand push handle is pushed forward toward the wall. The hand push handle drives the fixed seat to move forward, and the fixed seat drives the rebound cylinder to move forward. The rebound cylinder drives the rebound cylinder head and the fixed ring to move forward. The fixed ring drives the positioning ring and the buffer pad to move forward and contact the wall for positioning. Then the rebound cylinder head drives the striker to contact the wall. When the striker is pressed against the wall with force, it will rebound in the rebound cylinder. The tester will read and record the strength of the rebound, so as to infer the strength level of the concrete, thereby achieving the function of first positioning before the equipment performs strength testing on the concrete wall.

[0024] 2. The present invention is provided with a handle. When the device needs to be fixed and placed on a working plane, the handle needs to be split into two parts first. Then the handle and the curved rod are rotated to flip the handle to the bottom of the device. At this time, the handle becomes the support point of the device. The device is then placed on a plane to test the strength of concrete. In this way, the device can be moved by holding the handle and can be fixed or placed by using the handle as a support point. The striker can be used to strike the concrete surface to test the rebound degree of the concrete surface after the impact to infer the strength level of the concrete.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
