Description

Technical Field

[0001] This utility model relates to the field of hardness measurement technology, specifically to a device for measuring the hardness of building materials. Background Technology

[0002] Building materials are a general term for all materials used in construction projects. They are diverse and can be categorized in various ways. The main materials used to form the load-bearing structural system of a building include wood, bamboo, stone, cement, concrete, metal, bricks, ceramics, glass, engineering plastics, and composite materials. These materials possess sufficient strength, rigidity, and stability to withstand various loads on the building.

[0003] Hardness is an important performance indicator for measuring a material’s resistance to localized deformation, especially plastic deformation, indentation, or scratching. Hardness testing can be used to evaluate the overall performance of building materials, such as strength, abrasion resistance, and durability. Different building materials have different hardness requirements.

[0004] Traditional building material hardness measuring devices place the object to be tested on a support plate. During measurement, the object is compressed by the extrusion end of a pressure testing instrument. However, during this compression process, the object is prone to slippage or breakage, posing a safety hazard to workers and damaging the working environment. Therefore, those skilled in the art have provided a building material hardness measuring device to address the problems mentioned in the background section. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a building material hardness measuring device to solve the problem that the object being tested is prone to slippage or breakage during the compression process, which can endanger the safety of workers and damage the working environment.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a building material hardness measuring device, comprising a base, a first support mounted on the base, and a placement bucket mounted on the upper part of the first support. Due to the inverted conical outer wall of the placement bucket, the edges of materials of different specifications will be gradually limited by the narrowing inner wall when they come into contact with the inner wall of the placement bucket. A support plate is provided inside the placement bucket, and a screw is installed at the bottom of the support plate. A fixed sleeve is slidably sleeved on the periphery of the screw. A limit strip is installed on the inner wall of the fixed sleeve. A threaded sleeve is rotatably engaged at the upper opening of the fixed sleeve. A sliding groove is vertically opened on the outer wall of the screw. A cover plate is provided on the upper side of the placement bucket.

[0009] Preferably, a second bracket is installed on one side of the base, a compression cylinder is installed at the upper end of the second bracket, a pressure sensor head is installed at the lower output end of the compression cylinder, and a pressure sensor is installed on the second bracket. The compression cylinder drives the pressure sensor head to compress and measure the material, and the measurement data is collected and transmitted through the pressure sensor.

[0010] Preferably, the fixed sleeve is fixedly installed with the base, the limiting strip is slidably engaged with the slide groove, and the threaded sleeve is threadedly engaged with the screw. Rotating the threaded sleeve causes the screw to drive the support plate to rise and support the bottom of the material.

[0011] Preferably, a positioning bolt is installed on one side of the bottom of the cover plate, and a positioning hole is opened on the upper inner wall of the placement hopper. The positioning bolt is rotatably inserted into the positioning hole. After the cover plate is closed, the material is not easily ejected after being crushed under pressure, ensuring the safety of the testing personnel. Moreover, the fragments after crushing will fall onto the base along the inner wall of the placement hopper, which is convenient for cleaning and collection.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a device for measuring the hardness of building materials, which has the following beneficial effects:

[0014] By designing a system for measuring the hardness of building materials, the cover plate is flipped open, and the material is placed into the placement hopper. Due to the inverted conical outer wall of the placement hopper, the edges of materials of different specifications are limited when they come into contact with the inner wall of the placement hopper. Then, the threaded sleeve is rotated to make the screw drive the support plate to rise and support the bottom of the material. Subsequently, the cover plate is flipped open and closed, and the pressure cylinder drives the pressure sensor head to compress and measure the material. In this structure, after the material enters the placement hopper, it is supported and limited by the placement hopper and the support plate, which avoids the problem of the material slipping during measurement. Furthermore, after the cover plate is closed, the material is not easy to break out after being compressed, which ensures the safety of the testing personnel. The broken debris will fall onto the base along the inner wall of the placement hopper, which is convenient for cleaning and collection and avoids environmental clutter. Attached Figure Description

A sliding groove 701 is vertically opened on the outer wall of the screw 7. A cover plate 4 is provided on the upper side of the placement hopper 3. The fixing sleeve 5 is fixedly installed with the base 1. The limit strip 501 is slidably engaged with the sliding groove 701. The threaded sleeve 6 is threadedly sleeved with the screw 7. Rotating the threaded sleeve 6 causes the screw 7 to drive the support plate 8 to rise and support the bottom of the material. A positioning bolt 401 is installed on one side of the bottom of the cover plate 4, and a positioning hole 301 is opened on the upper inner wall of the placement bucket 3. The positioning bolt 401 is rotatably inserted into the positioning hole 301. After the cover plate 4 is closed, the material is not easy to break out after being squeezed, which ensures the safety of the inspection personnel. The broken debris will fall onto the base 1 along the inner wall of the placement bucket 3, which is convenient for cleaning and collection.

[0022] Please see Figure 1 , Figure 2 , Figure 3A second bracket 9 is installed on one side of the base 1. A compression cylinder 10 is installed on the upper end of the second bracket 9. A pressure sensor head 11 is installed on the lower output end of the compression cylinder 10. A pressure sensor 12 is installed on the second bracket 9. The compression cylinder 10 drives the pressure sensor head 11 to compress and measure the material. The measurement data is collected and transmitted through the pressure sensor 12.

[0023] In this utility model, a placement bucket 3 is installed on the base 1 via a first bracket 2, and a support plate 8 is provided in the middle of the placement bucket 3. A screw 7 is installed at the bottom of the support plate 8, and a fixing sleeve 5 is sleeved around the screw 7.

Then, the threaded sleeve 6 is rotated to make the screw 7 drive the support plate 8 to rise and support the bottom of the material. Then, the cover plate 4 is flipped open and closed. The compression cylinder 10 drives the pressure sensor head 11 to compress and measure the material. The measurement data is collected and transmitted through the pressure sensor 12. In this structure, after the material enters the placement hopper 3, it is supported and limited by the placement hopper 3 and the support plate 5, which avoids the problem of the material slipping during measurement.
