Description

Technical Field

[0001] The utility model relates to the technical field of sample detection equipment, in particular to sample detection equipment used for civil engineering materials. Background Art

[0002] In the practice of civil engineering, civil engineering material testing technology is an emerging technology that involves many aspects. Excellent engineering materials are indispensable in the process of engineering practice, and the development of high-quality engineering materials must rely on testing equipment. The preparation of civil engineering materials and the level of material performance directly affect the quality of the project. Engineering materials with high physical properties, chemical properties and mechanical properties have become an indispensable factor in the development of the civil engineering field.

[0003] Civil engineering building materials need to undergo quality inspection before they can be used in construction, but existing civil engineering material sample inspection devices can only inspect samples of fixed length. When inspecting the bending resistance of steel pipes, the spacing between the two support mechanisms cannot be adjusted according to the length of the steel pipe, which is not conducive to use. In order to solve the above problem, the patent document with announcement number CN 216284624U discloses a civil engineering material sample inspection device, which adjusts the spacing between the two support seats to match the length of the sample being tested.

[0004] However, when the above device is actually used, only a V-shaped groove is set on the support seat. When the detection block is pressed down for detection, since there is no component for limiting the position on the support seat, the end of the steel pipe will be lifted up when it is bent, causing a section of the steel pipe to be out of the V-shaped groove, resulting in inaccurate measurement or safety hazards. Utility Model Content

[0005] The utility model mainly provides a sample testing device for civil engineering materials, which solves the problem that in the prior art, only a V-shaped groove is arranged on a support seat. When the detection is performed by pressing down the detection block, since there is no component for limiting the position on the support seat, the end of the steel pipe will be tilted when it is bent, causing a section of the steel pipe to be separated from the V-shaped groove, resulting in inaccurate measurement or potential safety hazards.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A sample testing device for civil engineering materials, comprising a testing block, a movable plate and a support seat; a fixing mechanism is arranged on the support seat, and the fixing mechanism comprises two rotating seats symmetrically arranged on both sides of a V-shaped groove of the support seat, a connecting tube rotatably connected to each of the rotating seats, a sliding column slidably sleeved in the connecting tube, and a limit plate and a first through hole matching the sliding column is provided on the limit plate, a first anti-slip block is provided on the connecting tube, a second anti-slip block is provided at the inner end of the sliding column, a second through hole matching the sliding column is provided on the first anti-slip block, and a second through hole matching the sliding column is provided on the first anti-slip block, and a limit block for limiting the limit plate is detachably connected to the sliding column. When in use, after placing the steel pipe on the V-groove of the support seat, the limit plate is installed on the two sliding columns through the first through hole, and the two limit blocks are installed on the sliding column to limit the limit plate, and the limit plate is in the upper position of the steel pipe. When the steel pipe is supported and bent by the detection block, the structure of the limit plate and the sliding column will be driven upward by the steel pipe when it is upward, thereby preventing the steel pipe from bending and suddenly bouncing up within a certain distance, causing it to fall off the V-groove and causing inaccurate measurement. When the steel pipe bends from the middle to change the angle of the steel pipe sections on both sides, the limit plate, sliding column, connecting tube and other components will rotate with the cooperation of the rotating seat, thereby cooperating with the steel pipe to change the angle. By adopting the structure of the present application, the steel pipe can be limited within a distance at one end by means of a limit plate and other components, thereby preventing the steel pipe from bending and suddenly bouncing up, causing it to fall off the V-groove and causing inaccurate measurement; and the connecting tube and other components can be used to prevent the steel pipe from bending sideways, thereby achieving a left and right limiting effect similar to the V-groove, and the sliding connection between the connecting tube and the sliding column does not affect the upward displacement of the steel pipe, and the connecting tube is rotatably connected to the rotating seat, so that the angle can be adjusted in coordination with the steel pipe, and the overall safety is higher.

[0008] Furthermore, the sliding post is provided with a threaded section, and the limit block is threadedly connected to the sliding post. With this structure, disassembly and assembly are convenient and the connection is stable.

[0009] Furthermore, a support mechanism is provided at the bottom of the movable plate, and the support mechanism includes a mounting block mounted on the movable plate and a lifting screw connected to the mounting block by threading, the upper end of the lifting screw is rotatably connected to a horizontal plate frame, the horizontal plate frame is provided with a motor for driving the lifting screw to rotate, and the horizontal plate frame is provided with a limit rod, the lower end of the limit plate is fixedly connected to a support plate, the support plate is rotatably connected to the lower end of the lifting screw, and the mounting block is provided with a limit through hole for cooperating with the limit rod to slide. With this structure, the motor is arranged on the horizontal plate frame, its position is fixed and used to drive the lifting screw to rotate; it can drive the lifting screw to rotate after the movable plate moves, and drive the support plate to move up and down in the case of cooperating with the limit rod and the threaded connection, so as to support the movable plate; compared with the prior art, which will cause compression damage to the slide rail when pressed down, this structure is more convenient to use.

[0010] Furthermore, an anti-skid layer is provided at the lower end of the support plate, which drives the structure and can enhance the anti-skid effect.

[0011] Furthermore, the detection block is provided with a side limit mechanism, which includes a bidirectional screw rotatably connected to the detection block, and side guide rods arranged on both sides of the detection block, the bidirectional screw is threadedly connected with a side baffle, and the side baffle is provided with a side guide hole that matches the side guide rod. With this structure, the spacing between the baffles on both sides can be adjusted by rotating the bidirectional screw, so as to match steel pipes of different thicknesses and perform position limiting, thereby preventing the steel pipe from escaping from the lower position of the detection block from the side when pressed down, causing inaccurate detection.

[0012] Beneficial effects: By adopting the structure of the present application, the steel pipe can be limited within a distance at one end by means of a limit plate and other components, thereby preventing the steel pipe from bending and suddenly bouncing up, causing it to fall off the V-groove and causing inaccurate measurement; and the connecting tube and other components are used to prevent the steel pipe from bending sideways, thereby achieving a left and right limiting effect similar to the V-groove, and the sliding connection between the connecting tube and the sliding column does not affect the upward displacement of the steel pipe, and the connecting tube is rotatably connected to the rotating seat, so that the angle can be adjusted in coordination with the steel pipe, and the overall safety is higher.
