Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brick rebound testers, in particular to a high-precision brick rebound tester. Background Art
[0002] The brick rebound test hammer is a portable measuring tool used to test the strength of building materials such as bricks. The brick rebound test hammer uses a spring to impart a certain amount of kinetic energy to the impact hammer, which is then transferred to the brick sample via the impact rod. After the impact, the elastic reaction of the brick sample transmits the rebound energy back to the hammer through the impact rod. The hammer then moves the pointer slider until the rebound energy dissipates. The rebound value is then read from the instrument's scale at the position of the pointer slider's indicator line. However, the brick rebound test hammer has certain shortcomings, such as difficulty controlling perpendicularity to the brick during use. Excessive perpendicularity can easily lead to rebound value deviations, resulting in low accuracy. Therefore, a high-precision brick rebound test hammer has been developed. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.
[0024] The following describes some embodiments of the present invention in conjunction with the accompanying drawings to provide a high-precision brick rebound test hammer.
[0025] Example 1:
[0026] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides a high-precision brick rebound test hammer, including an instrument body 100, a tail cover 200, a sealing cover 300, a mounting ring 400, a vertical member 500 and an abutment block 600.
[0027] Specifically, the outside of the instrument body 100 is provided with a scale 101, a pointer block 102 and a retaining ring 103, and the inside of the instrument body 100 is provided with a striking rod 104. When in use, the striking spring can be used to enable the striking hammer to obtain a certain impact kinetic energy, and then the energy is transmitted to the brick sample through the striking rod 104. After the impact, the elastic reaction of the brick sample transmits the rebound energy back to the striking hammer through the striking rod 104. The striking hammer then drives the pointer block 102 to move until the rebound energy disappears. Finally, the reading of the position of the scale 101 of the pointer block 102 is read, that is, the rebound value.
[0028] Specifically, the tail cover 200 is threadedly connected to the top of the instrument body 100 . When in use, the tail cover 200 has a sealing effect so that the parts can be installed in the instrument body 100 .
[0029] Specifically, the sealing cover 300 is threadedly connected to the bottom of the instrument body 100, and the outer sides of the tail cover 200 and the sealing cover 300 are both provided with anti-slip grooves. When in use, the sealing cover 300 has a sealing effect so that parts such as the impact rod 104 can be installed in the instrument body 100.
[0030] Specifically, the mounting ring 400 is threadedly connected to the outside of the instrument body 100, a through-hole 401 is provided on the mounting ring 400, a fastening knob 402 is threadedly connected to the mounting ring 400, and a first buffer gasket 403 is bonded to the top of the mounting ring 400, and the three first buffer gaskets 403 are all provided with round holes for inserting the vertical rod 501. When in use, the mounting ring 400 is fixed to the instrument body 100 by means of threads, which is convenient for installation and disassembly, and the mounting ring 400 is used to install the vertical member 500, and the fastening knob 402 can be tightened. After tightening, the fastening knob 402 can be against the vertical rod 501 to fix the vertical member 500. The first buffer gasket 403 has an anti-wear effect, preventing the vertical member 500 from hitting the mounting ring 400 and wearing.
[0031] Specifically, the vertical member 500 includes a vertical rod 501 inserted into the through hole 401 and a fixing ring 502 arranged at the top of the vertical rod 501. The three vertical rods 501 are distributed in a circle. The bottoms of the three vertical rods 501 are all provided with threads. When in use, the mounting ring 400 can be inserted into the bottom of the instrument body 100 and threadedly connected. After connection, the vertical rod 501 of the vertical member 500 can be aligned with the through hole 401 of the mounting ring 400 and inserted. After insertion, the abutment block 600 can be aligned with the bottom of the vertical rod 501 and threadedly connected. After connection, the abutment block 600 can be first brought into contact with the brick, and the vertical piece 500 can be pinched by hand so that the abutment block 600, the vertical piece 500 and the mounting ring 400 are perpendicular to the brick. Then, the instrument body 100 can be held and moved in the direction of the brick to detect the resilience of the brick in a vertical state with high accuracy. Afterwards, the abutment block 600 can be rotated until the abutment block 600 is completely separated from the vertical rod 501, and then the vertical rod 501 can be pulled out from the mounting ring 400. Finally, the mounting ring 400 can be rotated to separate from the instrument body 100, thereby achieving a detachable assembly effect for easy transportation.
[0032] Specifically, the abutment block 600 is threadedly connected to the bottom of the vertical rod 501, and the top and bottom of the abutment block 600 are respectively bonded with a second buffer gasket 601 and a third buffer gasket 602, and the second buffer gasket 601 is provided with a circular hole for inserting the vertical rod 501. When in use, the second buffer gasket 601 and the third buffer gasket 602 both have an anti-wear effect. The second buffer gasket 601 can prevent the abutment block 600 from colliding with the mounting ring 400 and causing wear, while the third buffer gasket 602 can prevent the abutment block 600 from rubbing against the brick and causing wear.
[0033] The working principle and usage process of the present invention are as follows: when in use, the user can insert the mounting ring 400 into the bottom of the instrument body 100 and threadedly connect it. After connection, the vertical rod 501 of the vertical piece 500 can be aligned with the through hole 401 of the mounting ring 400 and inserted. After insertion, the abutment block 600 can be aligned with the bottom of the vertical rod 501 and threadedly connected. After connection, the abutment block 600 can be first brought into contact with the brick, and the vertical piece 500 can be pinched by hand so that the abutment block 600, the vertical piece 500 and the mounting ring 400 are perpendicular to the brick, and then the instrument body 100 can be held and moved in the direction of the brick to detect the resilience of the brick in the vertical state with high accuracy. Afterwards, the abutment block 600 can be rotated until the abutment block 600 is completely separated from the vertical rod 501, and then the vertical rod 501 can be pulled out from the mounting ring 400. Finally, the mounting ring 400 is rotated to separate from the instrument body 100, thereby achieving the effect of detachable assembly for easy transportation.
[0034] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
