[0002] Building materials are a general term for materials used in civil engineering and construction projects. There are many types of building materials, which can be roughly divided into inorganic materials, organic materials and composite materials. Building materials play an extremely important role in construction. Therefore, various performance tests are required for building materials used in various buildings to assess the quality of building materials. Before conducting various performance tests on building materials, sampling of building materials is required.

[0003] For example, the application number is CN202222912748.1. The utility model relates to the technical field of building material detection, specifically a building material detection sampler, including a force plate and a rotating plate, two fixed support rods arranged symmetrically between the force plate and the rotating plate, two force hand rods arranged symmetrically on the top of the force plate are welded, a sampling cannula is welded in the middle of the top of the rotating plate, the bottom end of the sampling cannula passes through the top of the rotating plate, and the outer wall of the sampling cannula and the position at the bottom of the rotating plate are movably connected with a positioning plate. The building material detection sampler is relatively small as a whole, which can be convenient for users to carry and operate. When using it, it is only necessary to place non-hard building materials such as foam boards between the positioning plate and the L-shaped base, then press the force hand rod downward, and rotate it left and right repeatedly, so that the blade of the sampling cannula cuts the building material in a circular manner, and the cut part enters the sampling cannula, and then the sampling cannula is pulled out to obtain a sample of the building material.

DETAILED DESCRIPTION

[0021] 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.

[0022] like Figures 1 to 3 As shown, the utility model provides a sampling and cutting device for building inspection, including a support frame 1, a sampling tube 2 and an annular blade 3, the top of the annular blade 3 is fixedly connected to the bottom of the sampling tube 2, a screw rod 4 is arranged inside the support frame 1, a screw sleeve 5 is threadedly connected to the top of the surface of the screw rod 4, transmission rods 6 are fixedly connected to both sides of the bottom of the screw sleeve 5, the bottom of the transmission rod 6 is fixedly connected to both sides of the top of the sampling tube 2, and clamping components 7 are arranged on the top of both sides of the inside of the sampling tube 2.

[0023] refer to Figure 3 The clamping assembly 7 includes a spring 71 and a clamping plate 72. The outer side of the clamping plate 72 is fixedly connected to one end of the spring 71 close to the clamping plate 72, and one end of the spring 71 away from the clamping plate 72 is fixedly connected to the tops of both sides of the inner wall of the sampling tube 2.

[0024] As a technical optimization scheme of the utility model, by setting the clamping assembly 7, during the process of storing the material inside the sampling tube 2, the clamping plate 72 will be squeezed by the material and move outward, and at the same time the spring 71 will be squeezed to generate a rebound force, and then the rebound force of the spring 71 will drive the clamping plate 72 to clamp the material stored in the sampling tube 2, and then when the user takes out the support frame 1, the material will be clamped in the sampling tube 2 to prevent the material from falling back to its original place.

[0025] refer to Figure 3 The top of the clamping plate 72 is fixedly connected to a limiting slider 8, and limiting grooves 9 are provided on both sides of the top of the inner wall of the sampling tube 2. The inner wall of the limiting groove 9 is slidably connected to the top surface of the limiting slider 8, and the cross-sections of the limiting slider 8 and the limiting groove 9 are both T-shaped.

[0026] As a technical optimization scheme of the utility model, by setting a limit slider 8 and a limit slot 9, it is convenient for the user to utilize the sliding connection between the limit slider 8 and the limit slot 9 and the cross-section of the limit slider 8 and the limit slot 9 to be T-shaped, so that the clamping plate 72 can be limited up and down, front and back, to avoid the situation where the clamping plate 72 is offset up and down, front and back during use, causing the spring 71 to be deformed and twisted, making it unusable.

[0027] refer to Figure 3 The bottom of the clamping plate 72 is fixedly connected with an oblique arc plate 10, and the material of the oblique arc plate 10 is PP plastic.

[0028] As a technical optimization scheme of the utility model, by setting the inclined arc plate 10, it is convenient for the user to guide the material stored in the sampling tube 2 through the inclined arc plate 10 when the clamping plate 72 is squeezed by the material, so that the material can smoothly enter the inner side of the clamping plate 72 and generate an outward squeezing force on the clamping plate 72, thereby avoiding the material from being stuck at the bottom of the clamping plate 72. The advantage of the low cost of PP plastic is utilized to reduce the cost of use.

[0029] refer to Figure 2 The bottoms of both sides of the inner wall of the support frame 1 are fixedly connected with the limiting sleeves 11, and the inner wall of the limiting sleeve 11 is slidably connected to the surface of the transmission rod 6.

[0030] As a technical optimization scheme of the utility model, by setting a limit sleeve 11, the limit sleeve 11 and the transmission rod 6 are used to slide together to limit the rotation of the screw sleeve 5, thereby preventing the screw sleeve 5 from directly driving the screw sleeve 5 to rotate when rotating, causing the screw sleeve 5 to be unable to move smoothly, thereby improving the stability of the screw sleeve 5 during use.

[0031] refer to Figure 2 The top of the screw rod 4 passes through the top of the support frame 1 and is fixedly connected to a limiting plate 12 , and the top of the limiting plate 12 is fixedly connected to a hand wheel 13 .

[0032] As a technical optimization solution of the utility model, by setting a limit plate 12, the limit plate 12 can be used to limit the screw 4 downward, so as to prevent the screw 4 from falling downward due to the lack of a support point during use. By setting a hand wheel 13, when the user needs to rotate the screw 4, the user can hold the hand wheel 13 and rotate it to drive the screw 4 to rotate, giving the user a point of force for easy application.

[0033] refer to Figure 2 A shaft rod 14 is fixedly connected to the right side of the top of the hand wheel 13 , and a grip sleeve 15 is movably sleeved on the surface of the shaft rod 14 .

[0034] As a technical optimization solution of the utility model, by setting the shaft 14 and the grip sleeve 15, when the user needs to rotate the screw 4, the user can also hold the grip sleeve 15 and rotate it with the screw 4 as the center, thereby driving the screw 4 to rotate through the hand wheel 13, giving the user another way to drive the screw 4 to rotate.

[0035] The working principle and use process of the utility model are as follows: when the user needs to sample the material, the user places the support frame 1 above the material, and then the user rotates the screw rod 4, and utilizes the threaded connection between the screw rod 4 and the screw sleeve 5 so that the screw rod 4 will drive the screw sleeve 5 to move downward during the rotation, so that the screw sleeve 5 drives the sampling tube 2 and the annular blade 3 to move downward through the transmission rod 6, so that the annular blade 3 squeezes and cuts the material, thereby storing the cut material in the sampling tube 2, and then utilizes the threaded connection between the screw rod 4 and the screw sleeve 5 to lock the screw sleeve 5, thereby preventing the annular blade 3 from rebounding. At this time, the clamping plate 72 will be squeezed outward by the material, and the spring 71 will be squeezed to generate a rebound force, and then the rebound force of the spring 71 will drive the clamping plate 72 to clamp the material stored in the sampling tube 2, and then when the user takes out the support frame 1, the material will be clamped in the sampling tube 2 to prevent the material from falling back to its original place, and has the ability to prevent the annular blade 3 from rebounding.

[0036] To sum up: the sampling and cutting device for building inspection, by setting a screw rod 4 and utilizing the threaded connection between the screw rod 4 and the screw sleeve 5, can lock the screw sleeve 5, thereby avoiding the rebound of the annular blade 3, and solves the problem of relying solely on pressing the handle to drive the blade to move downward to cut and sample the material. If the user presses the handle to drive the blade to cut and sample the material with good elasticity and there is a loss of force, the blade is easily affected by the material with good elasticity, causing the blade to move upward, thereby reducing the problem of cutting and sampling efficiency.
