Description

Technical Field

[0001] The utility model relates to the technical field of roughness meters, in particular to a roughness meter that is easy to clean. Background Art

[0002] A roughness meter is an instrument used to measure the surface roughness of an object. It assesses surface irregularities, concavities and convexities, and microstructural features. A roughness meter can measure various surface roughness parameters, such as average roughness, peak-to-valley height, and peak-to-valley spacing, to quantify surface quality and roughness. This data is crucial for many industries and applications, including manufacturing, automotive engineering, aerospace, and medical device manufacturing.

[0003] A traditional roughness tester usually consists of a sensor, a mechanical or electronic movement system, a data acquisition and processing unit (for collecting and analyzing measurement data), and a display or output device (for displaying or recording measurement results). These components work together to enable the roughness tester to accurately measure and evaluate the roughness characteristics of the surface.

[0004] Traditional roughness testers are typically integrated, preventing disassembly or assembly. This design limits access to the instrument's internal components for maintenance and cleaning. Furthermore, because the instrument's components are integrated, damage or problems with any component may require replacement or repair of the entire unit, increasing maintenance costs and time, and impacting the instrument's practicality. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a roughness meter that is easy to clean, aiming to improve the roughness meter which is usually an integrated design that does not allow users to disassemble or assemble it, limiting the user's maintenance and cleaning of the internal components of the instrument.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a roughness meter that is easy to clean, comprising a first shell, a second shell being slidably connected to one side of the first shell, a buckle being fixedly connected to one side of the first shell, a buckle being fixed inside the second shell, a connecting column being slidably connected inside the buckle, the connecting column being slidably connected inside the second shell, one end of the connecting column being fixedly connected to a handle, a sliding column being slidably connected inside the connecting column, one end of the sliding column being fixedly connected to a block, a spring being provided on the outer wall of the sliding column, one end of the spring being fixedly connected to one end of the connecting column, the other end of the spring being fixedly connected to one side of the block, a rotating column being rotatably connected inside the block, and a sliding assembly being provided on the outer wall of the rotating column.

[0007] Furthermore, the sliding assembly includes a pulley, the interior of the pulley is rotatably connected to the outer wall of the rotating column, and the outer wall of the pulley is slidably connected to the interior of the second shell.

[0008] Furthermore, a fixing plate is fixedly connected to the side wall of the second shell, and a connecting block is fixedly connected inside the fixing plate.

[0009] Furthermore, a fixing block is fixedly connected to the top of the connecting block, and a rotating frame is rotatably connected inside the fixing block.

[0010] Furthermore, a sliding groove is provided inside the rotating frame, and a ball is rotatably connected inside the fixing plate.

[0011] Furthermore, a threaded rod is fixedly connected to the outer wall of the sphere, and the threaded rod is slidably connected to the inside of the sliding groove.

[0012] Furthermore, a clamping ring is threadedly connected to the outer wall of the threaded rod, and a screw is fixedly connected to the top of the clamping ring.

[0013] Furthermore, the inner thread of the screw is connected to the outer wall of the threaded rod.

[0014] Furthermore, a clamping block is fixedly connected to the bottom of the rotating frame.

[0015] Furthermore, a handle is fixedly connected to one side of the rotating frame.

[0016] The utility model has the following beneficial effects:

[0017] 1. In the utility model, the roughness meter can be quickly disassembled and assembled through the cooperation between the first shell and the second shell, the buckle, the connecting column, the handle, the spring, the block and the slide column, which solves the problem that the roughness meter is usually an integrated design, which does not allow the user to disassemble or assemble it, and limits the user's maintenance and cleaning of the internal components of the instrument, thereby improving the practicality of the roughness meter.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figure 1 、 Figure 3 and Figure 4 , the utility model provides an embodiment: a roughness meter that is easy to clean, including a first shell 1, one side of the first shell 1 is slidingly connected to the second shell 2, one side of the first shell 1 is fixedly connected to a buckle 3, the inside of the second shell 2 is fixed with a buckle 3, the inside of the buckle 3 is slidingly connected to a connecting column 4, the connecting column 4 is slidably connected to the inside of the second shell 2, one end of the connecting column 4 is fixedly connected to a handle 5, the inside of the connecting column 4 is slidingly connected to a sliding column 10, one end of the sliding column 10 is fixedly connected to a block 7, the outer wall of the sliding column 10 is sleeved with a spring 6, one end of the spring 6 is fixedly connected to one end of the connecting column 4, and the other end of the spring 6 is fixedly connected to one side of the block 7, the inside of the block 7 is rotatably connected to a rotating column 8, the outer wall of the rotating column 8 is provided with a sliding assembly, the sliding assembly includes a pulley 9, the pulley 9 is rotatably connected to the outer wall of the rotating column 8, and the outer wall of the pulley 9 is slidably connected to the inside of the second shell 2.

[0028] Specifically, when the roughness meter needs to be disassembled and assembled, first put the first shell 1 and the second shell 2 together. At this time, the buckle 3 connected to one side of the first shell 1 squeezes the block 7 inside the second shell 2, so that the block 7 is forced to drive the rotating column 8 connected to the internal rotation to move. The rotating column 8 is forced to drive the pulley 9 connected to the outer wall rotation to slide inside the second shell 2, and at the same time, the block 7 is forced to squeeze the spring 6 fixedly connected on one side to contract. The spring 6 is forced to drive the connecting column 4 fixed at one end to slide inside the buckle 3 and the second shell 2. The buckle 3 then moves to the rear of the block 7. At this time, the spring 6 unloads the force and rebounds, thereby driving the block 7 to reset. The buckle 3 is clamped inside the second shell 2 and fixed by the movement of the block 7. When disassembling, you only need to pull the handle 5 to drive the connecting column 4 to move, thereby achieving the effect that the roughness meter can be quickly disassembled and assembled and easily cleaned.

[0029] Reference Figure 2 and Figure 5 The side wall of the second shell 2 is fixedly connected to a fixed plate 11, a connecting block 12 is fixedly connected inside the fixed plate 11, a fixed block 13 is fixedly connected to the top of the connecting block 12, a rotating frame 14 is rotatably connected inside the fixed block 13, a sliding groove 15 is opened inside the rotating frame 14, a sphere 16 is rotatably connected inside the fixed plate 11, a threaded rod 17 is fixedly connected to the outer wall of the sphere 16, and the threaded rod 17 is slidably connected inside the sliding groove 15.

[0030] Specifically, to carry the roughness tester, first rotate the rotating frame 14. This force causes the rotating frame 14 to rotate within the fixed block 13, simultaneously moving the clamping block 20, which is fixed at the bottom, to the side of the second housing 2. Next, rotate the screw 19, which, under the force of the screw 19, causes the retaining ring 18, which is fixed at the bottom, to rotate on the outer wall of the threaded rod 17. The threaded connection between the threaded rod 17, screw 19, and retaining ring 18 causes the screw 19 and retaining ring 18 to move, achieving the driving effect.

[0031] Reference Figure 2 and Figure 5 The outer wall of the threaded rod 17 is threadedly connected with a snap ring 18, the top of the snap ring 18 is fixedly connected with a screw 19, the inner thread of the screw 19 is connected to the outer wall of the threaded rod 17, the bottom of the rotating frame 14 is fixedly connected with a clamping block 20, and one side of the rotating frame 14 is fixedly connected with a handle 21.

[0032] Specifically, the retaining ring 18 is then moved to the top of the rotating frame 14 to secure it. This secures the clamping block 20 to one side of the second housing 2. Simultaneously, the rotating frame 14 also secures the handle 21, which is fixed to one side, to the side of the second housing 2. This series of steps makes the roughness tester more portable, making it more convenient to carry and move, and suitable for use in various occasions.

[0033] Working principle: When the roughness meter needs to be disassembled and assembled, first put the first shell 1 and the second shell 2 together. At this time, the buckle 3 connected on one side of the first shell 1 squeezes the block 7 inside the second shell 2. The block 7 is forced to drive the rotating column 8 connected to the internal rotation to move. The rotating column 8 is forced to drive the pulley 9 connected to the outer wall rotation to slide inside the second shell 2. At the same time, the block 7 is forced to squeeze the spring 6 fixed on one side to shrink. The spring 6 is forced to drive the connecting column 4 fixed at one end to slide inside the buckle 3 and the second shell 2. Then the buckle 3 moves to the back of the block 7. At this time, the spring 6 unloads the force and rebounds, thereby driving the block 7 to reset. The buckle 3 is stuck in the second shell 2 and fixed by the movement of the block 7. When disassembling, you only need to pull the handle 5 to drive the connecting column 4 to move. Yes, thereby achieving the effect that the roughness meter can be quickly disassembled and assembled for easy cleaning. When the roughness meter needs to be carried, first rotate the rotating frame 14. The rotating frame 14 is forced to rotate inside the fixed block 13. At the same time, the rotating frame 14 drives the clamping block 20 fixed at the bottom to move to the side of the second shell 2. At this time, rotate the screw 19. The screw 19 is forced to drive the clamping ring 18 fixed at the bottom to rotate on the outer wall of the threaded rod 17. Through the threaded connection between the threaded rod 17, the screw 19 and the clamping ring 18, the screw 19 and the clamping ring 18 move, and then the clamping ring 18 moves to the top of the rotating frame 14 to fix it, thereby fixing the clamping block 20 to one side of the second shell 2. At the same time, the rotating frame 14 also drives the handle 21 fixed on one side to be fixed to the side of the second shell 2, thereby achieving the effect of easy portability of the roughness meter.
