Description

Technical Field

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

[0002] In the field of construction engineering, material quality testing is a key link in ensuring the structural safety and performance of engineering projects. Sampling, as the first step in the testing process, directly determines the accuracy of subsequent test results through its standardized operation and sampling quality. Gypsum board, as a lightweight board commonly used in interior decoration projects, is widely used in wall partitions, ceiling decorations, and other scenarios due to its good fire resistance, sound insulation, and ease of construction. Whether its quality meets the standards (such as core material density, board thickness uniformity, and bonding strength between the surface layer and the core material) is crucial to the interior decoration effect and safety of use. Therefore, it is necessary to sample and test gypsum board using professional sampling equipment. However, existing manual sampling of gypsum board is prone to irregular sampling edges due to improper force control, making it difficult to obtain complete core material samples. At the same time, simple drilling devices lack anti-deviation structures, and the gypsum board is prone to shifting and shaking during sampling due to the smooth surface of the board or uneven force. Furthermore, the gypsum board core material is easy to get stuck in the sampling tube, requiring the use of additional tools to remove it, which not only damages the sample but also affects efficiency. Summary of the Invention

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a sampling device for sampling building materials. This device facilitates gypsum board sampling, ensures complete sampling, and allows for rapid sample removal from the sampling tube. It also features a simple structure, easy operation, and low cost. Furthermore, its anti-deviation structure prevents sampling offset, thus improving or solving the problems associated with manual gypsum board sampling, which is prone to irregular sampling edges due to improper force control, making it difficult to obtain complete core material samples. Additionally, simple drilling devices lack anti-deviation structures, making it prone to deviation and shaking during sampling due to smooth board surfaces or uneven force. Moreover, gypsum board core material can easily get stuck in the sampling tube, requiring additional tools for removal, which not only damages the sample but also affects efficiency.

At the same time, the simple drilling device lacks an anti-deviation structure, and the sampling is prone to deviation and shaking due to the smooth surface of the board or uneven force. Moreover, the gypsum board core material is easy to get stuck in the sampling cylinder, which requires the use of additional tools to remove it, which not only easily damages the sample, but also affects efficiency.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0019] Example 1, referring to Figure 1-4 This is the first embodiment of the present invention, which provides a sampling device for sampling building materials, including a base plate 1, an L-plate 2 fixedly connected to the rear end of the upper surface of the base plate 1, a screw 3 provided on the front side of the upper end of the L-plate 2, the lower end of the screw 3 passing through the L-plate 2 and threadedly connected to the L-plate 2, a sampling cylinder 4 fixedly connected to the lower end of the screw 3, a crank handle 5 fixedly connected to the upper end of the screw 3, a material sampling component 6 provided inside the sampling cylinder 4, and an anti-deviation component 7 provided at the lower end of the screw 3.

[0020] Specifically, it has the advantages of facilitating gypsum board sampling, ensuring complete sampling, and easily removing samples from the sampling tube 4. It also features a simple and easy-to-operate structure with low cost and a stable sampling process that prevents deviation.

[0021] Furthermore, the crank handle 5 drives the screw 3 to move down along the L plate 2, thereby driving the sampling cylinder 4 to cut the gypsum board. The anti-deviation component 7 limits the screw 3 to prevent deviation. The material taking component 6 assists in sampling and quickly pushes out the sample. All components work together to achieve a stable, complete and convenient gypsum board sampling operation.

[0022] Example 2, the second embodiment of this utility model, the sampling cylinder 4 is provided with moving grooves 8 on the left and right sides respectively, and both moving grooves 8 penetrate into the interior of the sampling cylinder 4. A serrated cutting edge 9 is provided on one side of the bottom end of the sampling cylinder 4. The sampling assembly 6 includes a push plate 61, a push spring 62, a vertical plate 63, and a pull-down plate 64. The push plate 61 is located inside the lower end of the sampling cylinder 4 and is slidably connected to the sampling cylinder 4. The push spring 62 is located inside the sampling cylinder 4 and its upper and lower ends are fixedly connected to the upper surface of the sampling cylinder 4 and the upper surface of the push plate 61, respectively. There are two vertical plates 63, which are fixedly connected to the left and right sides of the upper surface of the push plate 61, and correspond to the positions of the two moving slots 8. There are two pull-down plates 64, which are located on the left and right sides of the lower end of the sampling cylinder 4, and correspond to the positions of the two moving slots 8. The ends of the two pull-down plates 64 that are close to each other extend into the sampling cylinder 4 through the two moving slots 8, and are fixedly connected to the surfaces of the two vertical plates 63 that are far apart from each other. Both pull-down plates 64 have several anti-slip textures 10 on their upper surfaces; A rubber anti-slip block 11 is fixedly connected to the upper surface of the base plate 1. An annular knife groove 12 is provided on the upper surface of the rubber anti-slip block 11. The annular knife groove 12 corresponds to the lower end of the sampling cylinder 4 and is adapted in shape.

[0023] Specifically, by setting up the material picking component 6, the serrated blade edge 9 ensures the integrity of the gypsum board sampling. The push plate 61 and the push spring 62 work together to achieve rapid sample removal. The rubber anti-slip block 11 prevents the board from shifting. The annular blade groove 12 protects the blade edge. The pull-down plate 64 with anti-slip texture 10 improves the ease of operation, taking into account both sampling quality and operational efficiency.

[0024] Furthermore, during sampling, the gypsum board sample enters the sampling cylinder 4 and is pushed upwards by the push plate 61, which compresses the push spring 62. After sampling, the pull-down plate 64 with anti-slip texture 10 is pulled down, which drives the push plate 61 to move down through the upright plate 63. At the same time, the push spring 62 releases elastic potential energy to help push the sample out, and the rubber anti-slip block 11 fixes the board, and the annular blade groove 12 protects the serrated cutting edge 9, ensuring stable and efficient sampling and material handling.

[0025] Example 3, the third embodiment of this utility model, the anti-deviation component 7 includes a limiting ring 71, a rotating plate 72 and limiting rods 73. The limiting ring 71 is sleeved on the lower end surface of the screw 3 and is fixedly connected to the screw 3. The rotating plate 72 is sleeved on the surface of the limiting ring 71 and is rotatably connected to the limiting ring 71. There are two limiting rods 73, which are fixedly connected to the left and right sides of the upper surface of the rotating plate 72 respectively. The upper ends of the two limiting rods 73 penetrate the upper end of the L plate 2 and are slidably connected to the L plate 2.

[0026] Specifically, by setting the anti-deviation component 7, a stable vertical limit can be formed on the downward-moving screw 3, effectively preventing the screw 3 from radially deviating due to uneven force, ensuring that the sampling cylinder 4 is always vertically aligned with the sampling area, ensuring accurate sampling size, and the structure is simple without the need for additional driving components, low cost and easy maintenance.

[0027] Furthermore, when the crank handle 5 is rotated to drive the screw 3 to move downward along the threaded hole of the L plate 2, the limiting ring 71, which is fixedly connected to the screw 3, rotates and moves downward synchronously with the screw 3. Since the rotating plate 72 is sleeved on the surface of the limiting ring 71 and is rotatably connected to the limiting ring 71, and the limiting rods 73 on both sides of the rotating plate 72 pass through the L plate 2 and are slidably connected to the L plate 2, the limiting rods 73 can restrict the rotating plate 72 from rotating synchronously with the limiting ring 71, and only allow the rotating plate 72 to move vertically downward with the limiting ring 71. In this process, the limiting rods 73 and the rotating plate 72 cooperate to form a radial constraint on the screw 3, preventing the screw 3 from tilting or shifting due to force imbalance when cutting and sampling, thereby ensuring that the sampling cylinder 4 always maintains a vertical posture when cutting the gypsum board, improving the sampling accuracy and stability.

[0028] Working principle: During use, the gypsum board is placed on the rubber anti-slip block 11 on the upper surface of the base plate 1, ensuring that the sampling area of ​​the gypsum board is precisely aligned with the annular blade groove 12 on the rubber anti-slip block 11. The rubber anti-slip block 11 increases the friction between the gypsum board and the base plate 1, preventing the board from shifting during sampling. The annular blade groove 12 provides cutting space for the serrated blade 9 at the bottom of the sampling cylinder 4, preventing the blade from directly contacting the base plate 1 and causing wear. Then, the crank handle 5 is turned, causing the screw 3 to move downward along the threaded hole of the L plate 2. The limiting ring 71 moves downward with the screw 3. The rotating plate 72, which is fitted on the surface of the limiting ring 71 and rotatably connected to it, does not rotate due to the limitation of the limiting rod 73, but only moves downward with the rotating plate 72. The limiting rods 73 at both ends of the rotating plate 72 slide up and down along the L plate 2. Through the sliding cooperation between the limiting rods 73 and the L plate 2, the screw 3 is vertically limited, effectively preventing the screw 3 from being moved downward. Due to uneven force, radial offset occurs. To ensure that the sampling cylinder 4 is always vertically aligned with the area to be sampled, when the serrated edge 9 at the bottom of the sampling cylinder 4 contacts the plasterboard, the handle 5 is continuously rotated to make the serrated edge 9 cut the plasterboard until the sampling cylinder 4 completely covers the required sample. At this time, the push plate 61 inside the sampling cylinder 4 moves upward under the pressure of the sample. The push spring 62 at the top of the push plate 61 is compressed and stores elastic potential energy. After sampling is completed, the handle 5 is rotated in the opposite direction to drive the sampling cylinder 4 upward to detach from the plasterboard. Then, the pull-down plates 64 on both sides of the sampling cylinder 4 are pulled down. The pull-down plates 64 drive the upright plate 63 and the push plate 61 to slide down along the inner wall of the sampling cylinder 4 through the moving groove 8. At the same time, the push spring 62 releases elastic potential energy to assist the push plate 61 to move down, and smoothly push out the plasterboard sample in the cylinder. The material can be picked up without the need for additional tools. The entire operation process takes into account the sampling stability, integrity and material picking convenience.

[0029] In summary, by using the base plate 1, L-plate 2, screw 3, sampling cylinder 4, crank handle 5, material handling assembly 6, push plate 61, push spring 62, upright plate 63, pull-down plate 64, anti-deviation assembly 7, limit ring 71, rotating plate 72, limit rod 73, moving groove 8, serrated cutting edge 9, anti-slip texture 10, rubber anti-slip block 11, and annular blade groove 12 in combination, it is possible to facilitate sampling of gypsum board, ensure the integrity of the sampling, and quickly remove the sample from the sampling cylinder. Moreover, the structure is simple, easy to operate, and low in cost, and the anti-deviation structure can prevent sampling deviation.
