Description

Technical Field

[0001] The utility model relates to the technical field of brick and tile detection, in particular to a protective device for detecting the flexural strength of building bricks and tiles. Background Art

[0002] Building bricks and tiles are board products made of clay and other inorganic non-metallic raw materials through molding, sintering and other processes. They are used to protect building roofs. Bricks and tiles need to be tested for strength before leaving the factory. The strength test of bricks and tiles is usually carried out by using a flexural testing machine to test the flexural strength of bricks and tiles by applying pressure to the bricks and tiles until they are broken.

[0003] However, since bricks and tiles will produce flying fragments at the moment of breaking under force, the existing brick and tile anti-bending test machine cannot automatically block the flying fragments of the broken bricks and tiles during the brick and tile breaking test process, the flying fragments may easily scratch the operator, posing certain safety hazards.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Embodiment 1

[0043] See also Figure 1-5 , the utility model provides a technical solution:

[0044] A protective device for testing the flexural strength of building bricks and tiles, comprising a testing machine 100 and a brick and tile member 101 to be tested placed at the bottom of the testing machine 100, and further comprising:

[0045] A support unit 1, disposed at the lower end of the testing machine 100, for supporting the testing machine 100 and the brick and tile member 101;

[0046] The detection unit 2 comprises a pressing component 22 for performing anti-bending detection on the brick and tile 101 and a protection component 21 arranged at the periphery of the pressing component 22 for blocking the flying fragments of the brick and tile 101 .

[0047] It should be noted that when in use, the brick and tile 101 is placed on the support unit 1, and the pressing component 22 moves downward to perform anti-bending test on the brick and tile 101. At the same time, the pressing component 22 synchronously drives the protective component 21 to move upward along the support unit 1, so that the periphery of the brick and tile 101 is blocked to prevent the brick and tile 101 from flying out and scratching the operator when it breaks.

[0048] As an improvement, Figure 1-2 As shown, the pressing assembly 22 includes:

[0049] The cylinder 221 is installed at the lower part of the testing machine 100;

[0050] A bottom plate 222 connected to the lower end of the cylinder 221;

[0051] There are two sets of lifting rods 223, which are respectively connected to both sides of the bottom plate 222;

[0052] The pressing block 224 is connected between the two sets of lifting rods 223 and is used to perform anti-bending test on the brick and tile member 101.

[0053] Further, such as Figure 1-4 As shown, the support unit 1 comprises:

[0054] An upper pad 13 is provided at the lower end of the testing machine 100 and is used to support the testing machine 100;

[0055] The frame blocks 131 are provided in two groups and are connected to the upper end of the upper pad 13 to support the bottom of the brick and tile member 101;

[0056] A support shaft 12 is fixedly connected to the lower end of the upper pad 13 and is used to support the bottom of the test area of ​​the brick and tile member 101 of the upper pad 13;

[0057] The lower pad 11 is connected to the lower end of the support shaft 12 and is used to cooperate with the support shaft 12 to support the upper pad 13 .

[0058] Furthermore, if Figure 3-5 As shown, the protection component 21 includes:

[0059] A through slot 211 is provided through the upper end of the upper pad 13;

[0060] The enclosure 212 is slidably inserted into the through slot 211;

[0061] The driving mechanism 213 is disposed at the upper end of the enclosure 212 and located at one side of the pressing assembly 22 , and is used to drive the enclosure 212 to rise and fall when the pressing assembly 22 detects the brick and tile parts 101 .

[0062] Wherein, the driving mechanism 213 comprises:

[0063] A bracket 2132 is installed on the upper end of the upper pad 13 and located on one side of the enclosure 212;

[0064] A driven shaft 2131, one end of which is rotatably inserted into the testing machine 100 and the other end of which is rotatably inserted into the bracket 2132;

[0065] A reversing gear 2133 is disposed outside the driven shaft 2131;

[0066] A first rack 2134 connected to the upper end of the enclosure 212 and meshing with the reversing gear 2133;

[0067] The second rack 2135 is disposed on one side of the lifting rod 223 and meshes with a side of the reversing gear 2133 opposite to the first rack 2134 .

[0068] In addition, if Figure 4 As shown, guide grooves 2121 are provided on both sides of the testing machine 100;

[0069] The initial end of the enclosure plate 212 is slidably inserted into the guide groove 2121 up and down.

[0070] Such a design ensures that when the enclosure 212 moves upward along the through groove 211 , the guide groove 2121 can further guide the enclosure 212 , thereby preventing the enclosure 212 from being deflected during the movement process.

[0071] It should be noted that: in the specific implementation process of the utility model, Figure 2-5As shown, the brick and tile 101 is placed on the frame block 131. Initially, the pressing block 224 is away from the upper end of the brick and tile 101, and the upper end of the enclosure 212 is flush with the surface where the upper end of the upper pad 13 is located. When the anti-bending test is performed, the cylinder 221 is started, and the cylinder 221 drives the lifting rod 223 to move downward through the bottom plate 222. The lifting rod 223 moves downward to the brick and tile 101 through the pressing block 224 and performs an anti-bending test on the brick and tile 101. At the same time, the lifting rod 223 drives the reversing gear 2133 to rotate during the downward movement. The reversing gear 2133 drives the enclosure 212 to move upward along the through groove 211 through the first rack 2134, so that the enclosure 212 cooperates with the testing machine 100 to surround the brick and tile 101. When the brick and tile 101 is broken, the enclosure 212 can block the flying fragments, thereby achieving the effect of automatically blocking the flying fragments to prevent the operator from being scratched.

[0072] When the anti-bending test is completed, the cylinder 221 drives the pressure block 224 to move upward for reset through the bottom plate 222, and the lifting rod 223 drives the first rack 2134 to move downward through the reversing gear 2133. The first rack 2134 drives the enclosure 212 to move downward along the through groove 211, so that the enclosure 212 is automatically reset, which is convenient for cleaning the brick and tile 101 fragments left on the frame block 131 after the test.
