Description

Technical Field

[0001] This utility model relates to the field of brick rebound tester technology, and in particular to a brick rebound tester for testing the compressive strength of wall bricks. Background Technology

[0002] Wall tiles (or simply wall tiles) are suitable for facade decoration in bathrooms, kitchens, and outdoor balconies. Tiling walls is an effective way to protect them from water splashes. They are not only used on walls but also as decorative elements along door and window edges, and are often used for baseboards. They are both aesthetically pleasing and protect the wall base from dirt caused by shoes or chair legs. Tiles used in pools and bathrooms need to be aesthetically pleasing, moisture-proof, and wear-resistant. To ensure the performance of wall tiles, a compressive strength test is necessary, typically conducted using a tile rebound hammer.

[0003] When conducting compressive strength tests on walls, different hammers are often needed for different types of bricks. Different hammers can better adapt to different types and sizes of bricks. However, current brick rebound hammers require different brick rebound hammers for different types of bricks, which is time-consuming and laborious. At the same time, it is also inconvenient for staff to carry multiple brick rebound hammers. Utility Model Content

[0005] A brick rebound tester for testing the compressive strength of wall bricks includes a brick rebound tester. A CNC display screen is fixedly installed on one side of the brick rebound tester. Slots are provided on both sides of the CNC display screen and the brick rebound tester. Among the multiple slots, the inner sides of two slots on the same side are slidably fitted with the same grip handle. A replacement shell is snapped onto the bottom of the brick rebound tester. A replacement mechanism is provided on the inner side of the replacement shell. A hammer head is provided at the bottom of the replacement shell.

The multiple rack sliders are all adapted to the same planar threaded disc, which facilitates the movement of multiple rack sliders by driving the planar threaded disc.

[0011] Specifically, the fixed ratchet has two protrusions on one side, and the flat threaded disc has two slots on one side. The two protrusions slide in the corresponding slots respectively. A return spring is fixedly installed on one side of the fixed ratchet, and the other end of the return spring is in contact with the flat threaded disc.

[0012] Specifically, a friction shell is fixedly fitted on the outer side of the planar threaded disc, which allows the operator to manually rotate the planar threaded disc to increase its friction.

[0020] Reference Figure 1-5 A brick rebound tester for testing the compressive strength of wall bricks includes a brick rebound tester 1. A numerical control display screen 2 is fixedly installed on one side of the brick rebound tester 1. Slots 3 are provided on both sides of the numerical control display screen 2 and the brick rebound tester 1. Among the multiple slots 3, the inner sides of two slots 3 located on the same side are slidably installed with the same grip handle 4. A replacement shell 11 is snapped onto the bottom of the brick rebound tester 1. A replacement mechanism is provided on the inner side of the replacement shell 11. A hammer head 12 is provided at the bottom of the replacement shell 11.

[0021] In this embodiment, the brick rebound tester 1 has a test chamber inside, a drive assembly 20 is fixedly installed on the top inner wall of the test chamber, and a spring 7 is fixedly installed on the bottom inner wall of the test chamber.

[0022] In this embodiment, a central guide rod 5 is fixedly installed at the bottom of the drive assembly 20, and a spring hammer 6 is slidably sleeved on the central guide rod 5. The other end of the spring tension spring 7 is connected to the top of the spring hammer 6.

[0023] In this embodiment, a transmission base 8 is fixedly installed at the bottom of the brick rebound tester 1. The transmission base 8 is in contact with the hammer head 2. An annular groove is opened at the bottom of the transmission base 8. A limiting ratchet 9 is fixedly installed on the inner wall of the top of the annular groove. Multiple limiting grooves 10 are opened on the outer side of the transmission base 8.

[0024] In this embodiment, a ratchet groove is provided on the top of the replacement housing 11, and a fixed ratchet 13 is slidably installed on the inner side of the ratchet groove. The fixed ratchet 13 meshes with the limiting ratchet 9. A reset metal block 15 is fixedly installed on one side of the fixed ratchet 13, and a reset groove is provided on one side of the replacement housing 11. The reset metal block 15 is slidably installed in the reset groove.

[0025] In this embodiment, the replacement mechanism includes a planar threaded disc 16 and a plurality of rack and pinion sliders 17. The planar threaded disc 16 is slidably mounted on the inner side of the replacement housing 11. A plurality of sliding holes 19 are provided on the outer side of the replacement housing 11. A rack and pinion slider 17 is slidably mounted on the inner side of each of the plurality of sliding holes 19. The plurality of rack and pinion sliders 17 are all adapted to the same planar threaded disc 16, so that the planar threaded disc 16 can drive the plurality of rack and pinion sliders 17 to move.

[0026] In this embodiment, two protrusions are provided on one side of the fixed ratchet 13, and two slots are provided on one side of the flat threaded disc 16. The two protrusions slide in the corresponding slots respectively. A return spring 14 is fixedly installed on one side of the fixed ratchet 13, and the other end of the return spring 14 is in contact with the flat threaded disc 16.

[0027] In this embodiment, a friction shell 18 is fixedly sleeved on the outer side of the flat threaded disc 16, which makes it easy for the operator to manually rotate the flat threaded disc 16 to increase its friction.

[0028] Working principle: When testing the pressure of wall bricks, the operator holds the two handles 4 and activates the drive assembly 20 via the CNC display screen 2. The drive assembly 20 drives the impact hammer 6 to move. The impact hammer 6 strikes the transmission base 8 with constant kinetic energy. The transmission base 8 transfers the kinetic energy to the hammer head 12, which is in perpendicular contact with the brick surface, causing local brick deformation and absorbing some energy. The remaining energy is converted into the rebound kinetic energy of the impact hammer 6. When all the rebound kinetic energy is converted into potential energy, the impact hammer 6 rebounds to its maximum distance. The CNC display screen 2 shows the maximum rebound distance of the impact hammer 6 as the rebound value (maximum rebound distance and rebound...). The nominal ratio of the initial length of the spring 7 is displayed. When facing different bricks, the worker presses down the reset metal block 15. The reset metal block 15 moves, driving the fixed ratchet 13 to move. The fixed ratchet 13 moves down away from the limit ratchet 9. At this time, while the worker keeps pressing the reset metal block 15, the friction shell 18 is rotated counterclockwise. The rotation of the friction shell 18 drives the flat threaded disc 16 to rotate. The rotation of the flat threaded disc 16 drives multiple rack and pinion sliders 17 to move. The multiple rack and pinion sliders 17 move and slide out of the corresponding limit groove 10. At this time, the worker can replace the hammer head 12, which is more convenient and faster.

[0029] The technological advancements of this invention compared to existing technologies are as follows: the hammer head 12 can be disassembled or installed through the cooperation of the flat threaded disc 16 and the rack and pinion slider 17, making it convenient and quick to replace the hammer head 12 of the brick rebound tester 1, greatly improving the applicability of the equipment. At the same time, the design of the two grip handles 4 can increase the comfort of the staff when holding the equipment.
