[0001] The utility model relates to the field of sampling equipment for building quality management, in particular to a material sampling device for building quality management. Background Art

[0002] Construction quality management sampling equipment mainly involves various tools and instruments used to obtain samples of construction materials for quality inspection and analysis. These devices are crucial to ensuring the quality and safety of construction projects because they can help engineers evaluate whether the materials comply with relevant standards and regulations. However, the current sampling types include concrete sampling, soil sampling and steel sampling. In concrete sampling, the concrete needs to be introduced into the sampling box for subsequent samples.

[0003] At present, there are some problems in the preparation process of concrete samples. For example, before the sample is prepared, it is necessary to wait for the concrete to be completely dry before taking it out of the sampling box. However, when taking the dried concrete block out of the sampling box, the operation process is relatively cumbersome. It is usually necessary to turn the sampling box over and knock the concrete block out. This process is time-consuming and laborious, and may cause damage to the concrete block.

[0013] Furthermore, the top plate is fixedly connected to the movable shell, and a lever mechanism is provided on the top of the movable shell.

[0014] By adopting the above technical solution, the setting of the lever mechanism makes the sampling process more labor-saving, and the user can easily pull the movable shell and the sampling box out of the material through the lever principle, thereby improving work efficiency.

[0015] Furthermore, the lever mechanism includes a first connecting seat and a second connecting seat, the first connecting seat is arranged on the top of the movable shell, and the second connecting seat is arranged above both sides of the sampling box.

[0017] Furthermore, a third connecting rod is rotatably connected to the first connecting seat, a second connecting rod is rotatably connected to the top end of the third connecting rod, and the second connecting rod is connected to an end point of the third connecting rod.

[0018] By adopting the above technical solution, the rotational connection between the third connecting rod and the second connecting rod enables the lever mechanism to flexibly perform a lever action to meet the sampling requirements of materials of different depths and hardnesses.

[0019] Furthermore, a first connecting rod is rotatably connected to the second connecting seat, and the first connecting rod is rotatably connected to the outer side of the second connecting rod.

[0020] By adopting the above technical solution, the two groups of lever mechanisms are mirror-imaged along the central axis of the sampling box, making the sampling process more uniform and stable, and reducing the sampling error caused by uneven force.

[0028] 1. The utility model is provided with a push block, a top plate, a movable mechanism, and a fixing hole. When the wet concrete is filled into the collecting slot, the movable shell is firmly fixed to a fixed hole of the slide slot by a fixing bolt, thereby effectively supporting the sampling box and preventing deformation and concrete overflow during the sampling process. At the same time, the blocking effect of the movable shell ensures that the user cannot press the top plate, further ensuring the integrity and stability of the wet concrete in the sampling box. When the concrete dries to form a concrete block, the staff only needs to loosen the fixing bolts on the movable shell, and the movable shell can be easily moved up in the slide slot to expose the top plate. At this time, the staff can easily press down the top plate and use the push block to smoothly push the concrete block out of the collecting slot. This design not only avoids the trouble of disassembling the entire sampling box or using complex tools, but also greatly improves the efficiency and convenience of sampling work;

[0029] 2. The utility model sets a lever mechanism, and the top plate is fixedly connected to the movable shell to ensure the synchronization of the two when they move, laying the foundation for the subsequent lever mechanism operation. At the same time, the lever mechanism effectively acts on the movable shell through the setting of the first connecting seat and the second connecting seat to achieve force transmission and amplification. The third connecting rod on the first connecting seat is rotatably connected to the second connecting rod, and the first connecting rod on the second connecting seat is rotatably connected to the outer side of the second connecting rod to form a lever system. In order to enhance the stability and efficiency of the operation, two groups of lever mechanisms are set, which are mirror-imaged along the central axis of the sampling box to ensure structural balance and uniform force distribution. Its main function is to pry the movable shell to expose the top plate, which is convenient for the staff to further operate and push the concrete block out by pushing the block. In addition, the lever mechanism is made of stainless steel to ensure strength and corrosion resistance for long-term use.

[0030] 3. The utility model is provided with an anti-collision edge, which can effectively reduce the damage to the device caused by accidental collision or falling of the sampling box during transportation, storage or use. Since the sampling box is usually used for concrete sampling work at the construction site, the working environment is complex and changeable, and collision and falling are prone to occur. The setting of the anti-collision edge can increase the buffering performance of the edge of the device and reduce the direct effect of the impact force on the sampling box, thereby protecting its structural integrity and stability.

DETAILED DESCRIPTION

[0036] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0037] The following describes an embodiment of the utility model based on its overall structure.

[0038] Embodiment 1:

[0039] A material sampling device for building quality management, such as Figure 1-Figure 4 As shown, it includes a sampling box 1, a slide groove 2 is arranged on the outside of the sampling box 1, and a movable mechanism 7 is slidably connected to the inside of the slide groove 2 through a slide rod, and the movable mechanism 7 includes a movable shell 701, and a plug hole 702 is arranged on the outside of the movable shell 701, and the plug hole 702 is slidably connected with the slide rod;

[0040] Two fixing holes 8 are arranged inside the slide groove 2, and the two fixing holes 8 can be respectively positioned opposite to the plug-in holes 702, and the fixing holes 8 and the plug-in holes 702 can be threadedly connected with fixing bolts, and the fixing bolts can fix the movable shell 701 at different positions respectively;

[0041] The top of the sampling box 1 is provided with a collecting slot 3, and a push block 5 is slidably connected inside the collecting slot 3. A push rod is provided at the bottom of the push block 5, and the push rod passes through the sampling box 1 and is provided with a top plate 6. The sampling box 1, as the main structure of the entire device, provides a stable and closed environment for accommodating and protecting the sampling materials. This helps to ensure the accuracy of sampling and the integrity of the materials, and the design of the chute 2 allows the movable mechanism 7 to slide smoothly along the preset track. This design ensures both the flexibility of the activity and the stability of the structure. The movable mechanism 7 and its movable shell 701 are connected to the sampling box 1 through the chute 2, and can be easily moved and adjusted to meet different sampling requirements. As a part of the movable mechanism, the movable shell 701 provides a stable support and connection point.

[0042] See also Figure 1 , Figure 2 The sampling box 1 is arranged in a rectangular structure, and four slide grooves 2 are arranged in a circular array. The rectangular structure of the sampling box 1 has a stable geometric shape. This design can provide strong structural rigidity, ensuring that the sampling box will not be deformed or damaged during the sampling process, thereby ensuring the accuracy and effectiveness of the sampling. Moreover, the four slide grooves 2 are arranged in a circular array. This design allows the movable mechanism 7 to move flexibly around the sampling box, making it convenient for users to perform sampling operations from all directions, thereby improving the convenience of use.

[0043] See also Figure 1 , Figure 2The sampling box 1 is made of engineering plastic, and the movable shell 701 is used to support the sampling box 1. The engineering plastic material makes the sampling box 1 relatively light and easy to carry and move. At the same time, engineering plastic has good durability and can resist certain impacts and wear, thereby extending the service life of the sampling box. Moreover, engineering plastic usually has good corrosion resistance and can maintain its stable performance in a variety of environments. It is not easily corroded by chemical substances and is suitable for various complex sampling environments.

[0044] Embodiment 2:

[0045] See also Figure 1 , Figure 2 The top plate 6 is fixedly connected to the movable shell 701. A lever mechanism 9 is provided on the top of the movable shell 701. The fixed connection between the top plate 6 and the movable shell 701 ensures the stability and rigidity of the entire structure, so that when the movable shell 701 moves or is subjected to force, the top plate 6 can provide stable support to prevent the structure from loosening or deformation.

[0046] See also Figure 1 , Figure 2 The lever mechanism 9 includes a first connecting seat 901 and a second connecting seat 902. The first connecting seat 901 is arranged on the top of the movable shell 701, and the second connecting seat 902 is arranged above both sides of the sampling box 1. The first connecting seat 901 is located on the top of the movable shell 701, which provides a stable fulcrum for the lever to ensure stability during prying. At the same time, the second connecting seat 902 is located above both sides of the sampling box 1. Such a layout helps to disperse force and reduce the risk of excessive force on a single point.

[0047] See also Figure 1 , Figure 2 The first connecting seat 901 is rotatably connected to a third connecting rod 905, the top of the third connecting rod 905 is rotatably connected to a second connecting rod 904, and the second connecting rod 904 is connected to an end point of the third connecting rod 905. Since the third connecting rod 905 and the first connecting seat 901 and the third connecting rod 905 and the second connecting rod 904 are connected by rotation, the entire connecting rod mechanism has a high degree of freedom, can adapt to a variety of different motion requirements, and achieve a more flexible and changeable motion trajectory. Moreover, the end points of the third connecting rod 905 and the second connecting rod 904 are connected to form a stable triangular structure, which increases the stability of the entire connecting rod mechanism. This connection method can effectively resist external disturbances and ensure the stable operation of the mechanism in a complex environment.

[0048] See also Figure 1 , Figure 2The first connecting rod 903 is rotatably connected to the second connecting seat 902, the first connecting rod 903 is rotatably connected to the outer side of the second connecting rod 904, the rotational connection between the first connecting rod 903 and the second connecting seat 902, and the rotational connection between the first connecting rod 903 and the outer side of the second connecting rod 904 together increase the degree of freedom of the entire connecting rod mechanism. This design enables the mechanism to move flexibly in multiple directions to adapt to complex and changeable operational requirements. Through this connection method, the first connecting rod 903 and the second connecting rod 904 can rotate freely within a certain range, thereby expanding the motion range and reachable space of the entire mechanism, which is very important for mechanical equipment that needs to perform complex movements or reach specific positions.

[0049] See also Figure 1 , Figure 2 The lever mechanism 9 is provided with two groups, and the two groups of lever mechanisms 9 are mirror-set along the central axis of the sampling box 1. By mirror-setting the two groups of lever mechanisms 9 along the central axis of the sampling box 1, it can ensure that the sampling box remains balanced during operation and prevents tilting or tipping due to the center of gravity shift. This symmetrical design helps to enhance the stability of the entire system. The mirror-set lever mechanisms 9 can achieve uniform force on the sampling box 1 and avoid damage or deformation caused by excessive force on a single point. This helps to protect the sampling box and its internal samples and ensure the accuracy and reliability of sampling.

[0050] See also Figure 1 , Figure 2 , Figure 3 The lever mechanism 9 is used to pry the movable shell 701. After the movable shell 701 is pried, the concrete can be pushed out. The material of the lever mechanism 9 is stainless steel. The design of the lever mechanism 9 makes the sampling process more efficient. By prying the movable shell 701, the concrete sample can be easily pushed out of the sampling box, which reduces the tedious steps such as manual digging or knocking, and improves the sampling efficiency. Using the lever mechanism 9 for prying operation is more convenient than the traditional method. The operator only needs to use the lever principle to produce a larger prying effect with a smaller force, thereby easily completing the sampling work.

[0051] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 An anti-collision edge 4 is provided on the upper outer side of the sampling box 1. The anti-collision edge 4 is used to protect the sampling box 1. In complex environments such as construction sites, the sampling box 1 is easily impacted by external objects. The provision of the anti-collision edge 4 can effectively absorb and disperse the impact force, thereby preventing the sampling box 1 from being deformed or damaged due to the impact, protecting the integrity and functionality of the sampling box, and due to the protective effect of the anti-collision edge 4, the sampling box 1 can resist more physical impacts, so its service life will be significantly extended, which reduces the frequency of replacement due to damage and reduces maintenance costs.

[0052] The implementation principle of the utility model is as follows: first, during the use of the first embodiment, it is necessary to ensure that all components such as the sampling box 1, the chute 2, the movable mechanism 7, the lever mechanism 9, etc. are not damaged or missing, and slide the movable shell 701 in the chute 2 until the expected sampling depth or position is reached. When the movable shell 701 reaches the appropriate position, ensure that the plug hole 702 is aligned with the fixing hole 8, and use the fixing bolts to fix the movable shell 701 at the selected position. After that, the concrete can be introduced into the sampling slot;

[0053] When the concrete block is dry, loosen the fixing bolts to allow the movable shell 701 to move in the chute 2, pull the movable shell 701 upward, and then press the sampling box 1 downward. At this time, the push rod at the bottom of the push block 5 pushes the top plate 6, and the sample in the sampling box 1 can be ejected;

[0054] According to the second embodiment, when sampling, the operator stands on one side of the sampling device, and holds the second connecting rod 904 of the two groups of lever mechanisms 8 with both hands. Then, the operator applies downward pressure to the first connecting rod 903. At this time, the second connecting rod 904 and the third connecting rod 905 are lifted upward with the first connecting seat 901 as the fulcrum to form a lever effect. This action effectively pries the movable shell 701, and then the movable shell moves upward together with the sampling box. The operator continues to apply force until the movable shell 701 and the sampling box 1 are completely pulled out of the building material, completing the sampling process. The parts not involved in the utility model are the same as the prior art or can be implemented by the prior art, and no excessive elaboration is given here.

[0055] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
