Description

Technical Field

[0001] This utility model relates to the field of construction engineering quality testing technology, specifically a sampler for construction engineering quality testing. Background Technology

[0002] During the construction process, quality inspectors need to continuously conduct quality inspections on the project. Specifically, before construction begins, it is often necessary to take soil samples from specific locations on the construction site for testing. This process requires the use of a sampler to take soil samples.

[0003] For example, CN221426049U discloses a sampler for construction engineering quality testing, which relates to the field of auxiliary components for construction engineering quality testing. It includes a U-shaped bracket, which is inverted. A driving component is vertically inserted into the top of the U-shaped bracket, and a sampling component is vertically arranged between the two sides of the U-shaped bracket. The top of the sampling component is fixedly connected to the bottom of the driving component.

[0004] This patent allows the U-shaped bracket to be stably placed on the ground at the soil sampling location by stepping on the foot pedals on both sides, replacing the operation method of directly pressing down the sampling tube. However, during the sampling process, it is difficult to ensure that the sampling head can accurately sample the required soil by manually pressing down the sampling tube, and it is troublesome to repeatedly adjust the position of the sampling tube, resulting in low convenience. Utility Model Content

[0005] The purpose of this utility model is to provide a sampler for construction engineering quality testing, so as to solve the problems mentioned in the background art, that during the sampling process, it is difficult to ensure that the sampling head can accurately sample the required soil by manually pressing down the sampling cylinder, and it is troublesome and inconvenient to repeatedly adjust the position of the sampling cylinder.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sampler for quality testing of construction projects, comprising a support column. An angle adjustment mechanism is fixedly connected to the bottom end of the support column. The angle adjustment mechanism includes a first fixed column, which is fixedly connected to the bottom end of the support column. A motor is movably connected to the end of the first fixed column away from the support column. A connecting screw is fixedly connected to the inner cavity of the motor. A first connecting column is fixedly connected to the outer side of the connecting screw. The first connecting column is connected to the motor via the connecting screw. A corner column is hinged to the bottom end of the first connecting column. A connecting plate is hinged to the outer side of the corner column. A second connecting column is movably connected to the end of the connecting plate away from the corner column.

[0008] Furthermore, two corner columns are symmetrically arranged, and the two symmetrically arranged corner columns are connected by a connecting plate. The corner column located on the upper side is used to connect connecting column one and the connecting plate, and the corner column located on the lower side is used to connect the connecting plate and connecting column two.

[0009] Furthermore, a connector mechanism is fixedly connected to the bottom end of the second connecting column. The connector mechanism includes a second fixing column, which is fixedly connected to the bottom end of the second connecting column. A third connecting column is fixedly connected to the bottom end of the second fixing column.

[0010] Furthermore, a fixed threaded frame is fixedly connected to the bottom end of the connecting column three, and the inner cavity of the fixed threaded frame is provided with a thread.

[0011] Furthermore, a driven post is fixedly connected to one end of the fixed threaded frame, and a driving post is movably connected to the outside of the driven post.

[0012] Furthermore, the inner cavities of the fixed threaded frame, driven column, and driving column are movably connected to a threaded column, one end of which is fixedly connected to a placement column. The outer surface of the placement column is sloped, and the inner diameter of the placement column at the end away from the threaded column is slightly larger than the inner diameter at the end closer to the threaded column. A sampling head is movably connected to the inner cavity of the placement column.

[0013] Furthermore, a handle is fixedly connected to the top of the support column, and the support column and the handle are connected by a threaded connecting post to adjust the spacing.

[0014] This utility model has the following beneficial effects:

[0015] I. This utility model is equipped with an angle adjustment mechanism. When the motor starts, the connecting screw drives the first connecting column to rotate, and then transmits power through the hinged corner column and the connecting plate, causing the second connecting column to produce a corresponding angle change. The connecting plate, as the intermediate force transmission component, evenly transmits the power of the upper corner column to the lower corner column, avoiding deformation or jamming of the mechanism caused by single-point force. This linkage mechanism enables the sampling head to be precisely adjusted to the required angle, ensuring the accuracy and convenience of the sampling operation.

[0016] II. Based on the aforementioned beneficial effects, a connector mechanism is also provided. Fixed column two serves as a transition component, transmitting the power of connecting column two to connecting column three. It achieves a tight connection with other components through the threaded line of the fixed threaded frame. When the threaded column is rotated, the threaded line interacts with the thread in the inner cavity of the fixed threaded frame, causing the threaded column and the placement column to move up and down, thereby achieving precise adjustment of the sampling head height. The active column is manually rotated to drive the driven column to move synchronously, thus driving the threaded column to rise and fall smoothly, avoiding the sampling head from tilting due to uneven force. After the sampling head is inserted into the placement column, the slope structure fixes it through friction. After sampling is completed, the sampling head and sample can be removed with a slight rotation or push, improving operational efficiency. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-3 As shown, this utility model is a sampler for construction engineering quality testing, including a support column 1. An angle adjustment mechanism 3 is fixedly connected to the bottom end of the support column 1. The angle adjustment mechanism 3 includes a first fixed column 31, which is fixedly connected to the bottom end of the support column 1. A motor 32 is movably connected to the end of the first fixed column 31 away from the support column 1. A connecting screw 33 is fixedly connected to the inner cavity of the motor 32. A first connecting column 34 is fixedly connected to the outer side of the connecting screw 33. The first connecting column 34 is connected to the motor 32 through the connecting screw 33. A corner column 35 is hinged to the bottom end of the first connecting column 34. A connecting plate 36 is hinged to the outer side of the corner column 35. A second connecting column 37 is movably connected to the end of the connecting plate 36 away from the corner column 35.

[0029] For example, the motor 32 drives the connecting screw 33, which in turn drives the connecting column 34 and the corner column 35 to adjust their angles, so as to realize the sampler's flexible adjustment at multiple angles and adapt to the complex terrain requirements of different construction sites.

[0030] There are two symmetrical corner posts 35, which are connected by a connecting plate 36. The upper corner post 35 is used to connect the connecting post 1 34 and the connecting plate 36, and the lower corner post 35 is used to connect the connecting plate 36 and the connecting post 2 37.

[0031] For example, by symmetrically arranging two corner posts 35 and connecting them with a connecting plate 36, the stability and force transmission efficiency of the angle adjustment mechanism 3 are enhanced. The upper corner post 35 is responsible for connecting the power input part (connecting post one 34), and the lower corner post 35 is responsible for connecting the output part (connecting post two 37).

[0032] Working principle: When the motor 32 starts, the connecting screw 33 drives the connecting column 1 34 to rotate, and then transmits power through the hinged corner column 35 and connecting plate 36, causing the connecting column 2 37 to produce a corresponding angle change. The connecting plate 36, as the intermediate force transmission component, evenly transmits the power of the upper corner column 35 to the lower corner column 35, avoiding deformation or jamming of the mechanism caused by single-point force. This linkage mechanism enables the sampling head 5 to be precisely adjusted to the required angle, ensuring the accuracy and convenience of the sampling operation.

[0033] This step, through the angle adjustment mechanism 3, enables the sampling head 5 to be precisely adjusted to the required angle, ensuring the accuracy and convenience of the sampling operation.

[0034] Please see Figure 4-6As shown, this embodiment is based on the above embodiment and also includes a connector mechanism 4. The bottom end of the connecting column 2 37 is fixedly connected to the connector mechanism 4. The connector mechanism 4 includes a fixing column 2 41, which is fixedly connected to the bottom end of the connecting column 2 37. The bottom end of the fixing column 2 41 is fixedly connected to a connecting column 3 42.

[0035] For example, by connecting the angle adjustment mechanism 3 to the sampling part through the fixed column 2 41 and the connecting column 3 42, a modular design is achieved, which is convenient for disassembly and maintenance.

[0036] The bottom end of the connecting column 3 42 is fixedly connected to a fixed threaded frame 43, and the inner cavity of the fixed threaded frame 43 is provided with a threaded line;

[0037] For example, the threaded design of the inner cavity of the fixed threaded frame 43 allows the threaded post 46 to be raised and lowered by rotation, thereby controlling the depth of the sampling head 5 and meeting the sampling requirements at different depths.

[0038] One end of the fixed threaded frame 43 is fixedly connected to a driven post 44, and the outer side of the driven post 44 is movably connected to a driving post 45;

[0039] For example, the mating design of the driven post 44 and the driving post 45 enhances the stability of the threaded post 46 and prevents it from shifting during rotation.

[0040] A threaded post 46 is movably connected to the inner cavity of the fixed threaded frame 43, the driven post 44 and the driving post 45. A placement post 47 is fixedly connected to one end of the threaded post 46. The outer surface of the placement post 47 is sloped. The inner diameter of the end of the placement post 47 away from the threaded post 46 is slightly larger than the inner diameter of the end closer to the threaded post 46. A sampling head 5 is movably connected to the inner cavity of the placement post 47.

[0041] For example, the slope design and inner diameter variation of the placement column 47 enable the sampling head 5 to be tightly fixed and easy to replace, and the gradual inner diameter design also facilitates the smooth removal of the sample after sampling.

[0042] A handle 2 is fixedly connected to the top of the support column 1. The support column 1 and the handle 2 are connected by a connecting column with a threaded wire to adjust the spacing.

[0043] For example, the distance between the grip 2 and the support column 1 is adjusted by a threaded connection column to adapt to the operating habits and height requirements of different users.

[0044] Working principle: Fixed column 2 41 acts as a transition component, transmitting the power of connecting column 2 37 to connecting column 3 42, and achieving tight connection with other components through the threaded line of fixed threaded frame 43. When rotating threaded column 46, the threaded line interacts with the thread in the inner cavity of fixed threaded frame 43, driving threaded column 46 and placement column 47 to move up and down, achieving precise adjustment of the height of sampling head 5. The active column 45 drives the driven column 44 to move synchronously by manual rotation, thereby driving threaded column 46 to rise and fall smoothly, avoiding tilting of sampling head 5 due to uneven force. After sampling head 5 is inserted into placement column 47, the slope structure fixes it through friction. After sampling is completed, the sampling head 5 and sample can be removed with a slight rotation or push, improving operating efficiency.
