Description

Technical Field

[0001] The utility model relates to the technical field of rebound hammers, in particular to a cap used for rebound hammers. 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] After searching, a rebound tester (authorization announcement number: CN 211013889U) "comprises a rebound tester and a bracket, wherein the bracket comprises a guide rod, legs and a cross bar, wherein the cross bar is vertically arranged between two legs, and a guide rod is vertically arranged in the middle of the cross bar; the rebound tester is movably connected to the guide rod, and a rebound device is arranged between the rebound tester and the bracket".

[0004] According to the above-mentioned related technologies, the applicant believes that the rebound hammer in the above-mentioned technology lacks a protective mechanism for the rebound hammer test rod, the on-site environment of the rebound hammer is poor, and when the rebound hammer is not in use, the test rod of the rebound hammer is not protected. Dust, gravel and other impurities will enter the gap of the rebound hammer, which will affect the accuracy of the instrument and cause deviations in the test results. In response to the above problems, we have introduced a cap for the rebound hammer. Utility Model Content

The stabilizing component includes a sliding frame 504, which is fixedly connected to the outside of the dust cap 3. The sliding frame 504 is internally slidably connected to a sliding rod 505, and a spring 506 is sleeved on the outside of the sliding rod 505. One end of the sliding rod 505 away from the dust cover 501 is fixedly connected to a sliding block 507, and the other end of the sliding rod 505 extends to the outside of the dust cap 3 and is fixedly connected to a pressing plate 508.

[0024] In the above technical solution, considering that the on-site environment of the rebound hammer is poor, when the rebound hammer is not in use, the detection rod of the rebound hammer is not protected, and impurities such as dust and gravel will enter the gap of the rebound hammer, which will affect the accuracy of the instrument and cause deviations in the test results. In order to solve this problem, the specific operations are as follows:

[0025] Reference Figure 1 - Figure 5 In a preferred embodiment, the sliding block 507 is pushed to slide inside the sliding frame 504 toward the dust cover 501, and then the spring 506 is compressed, and the sliding rod 505 slides inside the sliding frame 504, so that the pressing plate 508 falls off from the inside of the card slot 8, and then the dust cover 501 drives the connecting frame 503 to rotate inside the rotating block 502 until the No. 1 Velcro 6 and the No. 2 Velcro 7 are fitted, and the dust cover 501 is adhered and fixed to the outer wall of the dust cap 3. Through the dustproof mechanism 5, when the rebound tester body 1 is not in use, the telescopic head 2 can be dustproofed to avoid dust or gravel from entering the connection between the telescopic head 2 and the rebound tester body 1, which affects the accuracy of the test result. The structure is simple and the practicability is strong.

[0026] Reference Figure 1 - Figure 5In a preferred embodiment, a controller 10 is fixedly connected to the outer wall of the rebound tester body 1, a display screen 11 is provided inside the controller 10, and a switch 12 is provided on the outer side of the controller 10. A base 9 is fixedly connected to the end of the rebound tester body 1 away from the telescopic head 2. A card slot 8 is provided on the side of the dust cover 501 away from the telescopic head 2, and the size of the card slot 8 is consistent with the size of the pressing plate 508. The rebound tester body 1 is electrically connected to the controller 10. Through the provided controller 10, the staff can control the opening and closing of the rebound tester body 1, and the operation is simpler. Through the provided base 9, when the rebound tester body 1 is not in use, the rebound tester body 1 can be placed vertically to reduce dust. Through the provided card slot 8, the dust cover 501 can be conveniently fixed.

[0027] Working principle: In actual use, the staff needs to open the dust cover 501. First, the staff pushes the sliding block 507 to slide inside the sliding frame 504 towards the dust cover 501, and then the spring 506 is compressed, and the sliding rod 505 slides inside the sliding frame 504, so that the pressing plate 508 falls off from the inside of the card slot 8, and then the dust cover 501 drives the connecting frame 503 to rotate inside the rotating block 502 until the No. 1 Velcro 6 and the No. 2 Velcro 7 fit together, and the dust cover 501 is adhered and fixed to the outer wall of the dust cap 3, and then the switch 12 on the controller 10 is used to open the rebound tester body 1, and the telescopic head 2 extends from the inside of the rebound tester body 1 to start working.

[0028] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this.
