Description

Technical Field

[0001] This utility model relates to the field of Shore hardness tester cleaning technology, and in particular to a Shore hardness tester indenter cleaning brush. Background Technology

[0002] Shore hardness testers are commonly used hardness testing instruments and are widely used in the hardness measurement of elastic materials such as rubber and plastics. The core testing component is the indenter assembly, which directly contacts the surface of the workpiece during measurement. Over long-term use, it is very easy to get contaminated with impurities, oil, or dust. If it is not cleaned in time, it may affect the sensitivity of the indenter, the response accuracy, and the accuracy of the final measurement results.

[0003] However, existing Shore hardness tester indenter cleaning brushes typically require manual disassembly for cleaning, making the cleaning process cumbersome and inefficient. Frequent disassembly can also cause the precision structure of the indenter assembly to loosen, wear, or even misalign, thus affecting the long-term stability of the equipment. Furthermore, the lack of effective structural guidance and cleaning path control during Shore hardness tester indenter cleaning often results in incomplete cleaning or accidental damage to the indenter. Therefore, this paper provides a Shore hardness tester indenter cleaning brush to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a Shore hardness tester indenter cleaning brush.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a Shore hardness tester indenter cleaning brush, comprising a Shore hardness tester, an indenter assembly at the bottom of the Shore hardness tester, a handheld assembly at the bottom of the Shore hardness tester, a cleaning assembly at the inner bottom of the handheld assembly, the cleaning assembly cooperating with the indenter assembly, and a rotating assembly at the bottom of the cleaning assembly, the rotating assembly cooperating with the handheld assembly.

[0006] As a further description of the above technical solution: the handheld component includes a cleaning block disposed at the bottom of the Shore hardness tester. A cleaning cavity is formed in the middle of the cleaning block, and the cleaning cavity cooperates with the pressure needle assembly. A transmission hole is formed in the bottom of the inner part of the cleaning cavity, and the transmission hole cooperates with the cleaning component. By setting the cleaning cavity to tightly cover the position of the pressure needle assembly, the cleaning brush is prevented from shifting, ensuring targeted cleaning. Moreover, the combination of the embedded cleaning cavity and the cleaning block makes the cleaning device not significantly increase the size of the equipment, making it easy to carry on site. At the same time, the transmission hole is an interface for providing power connection to the cleaning structure.

[0007] As a further description of the above technical solution: the handheld component also includes a handle disposed on one side of the cleaning block, a grip pad is sleeved in the middle of the handle, and a fixing ring is disposed at the end of the handle away from the cleaning block, and the fixing ring cooperates with the Shore hardness tester. The grip pad and the fixing ring are made of flexible rubber material. By setting the handle with a flexible grip pad, the grip comfort is increased and fatigue during long-term use is reduced, while the fixing ring firmly connects the handheld component to the hardness tester body, maintaining the rigid support and alignment accuracy of the cleaning component.

[0008] As a further description of the above technical solution: the cleaning component includes a transmission disk disposed inside the cleaning chamber, a transmission rod disposed at the bottom of the transmission disk, an assembly hole disposed at the bottom of the transmission rod, and the assembly hole cooperates with the rotating component, a transmission groove disposed inside the assembly hole, a cleaning brush disposed at the top of the transmission disk, an adapter hole disposed in the middle of the cleaning brush, and the adapter hole cooperates with the pressure needle component. By setting the transmission rod to extend the transmission disk to the bottom, it is ensured that power is effectively transmitted from the hand input to the cleaning brush. The adapter hole is precisely aligned with the pressure needle component to prevent the brush bristles from sweeping randomly, avoid damage to the pressure needle component and improve cleaning efficiency. Moreover, the cleaning brush and transmission disk have distinct structures, which facilitates disassembly and cleaning or replacement of brush heads of different materials to deal with different pollution conditions.

[0009] As a further description of the above technical solution: the rotating assembly includes a rotating disk disposed at the bottom of the transmission disk, an insertion slot is provided in the middle of the rotating disk, and the insertion slot cooperates with the transmission rod. An assembly rod is provided inside the insertion slot, and the assembly rod cooperates with the assembly hole. A transmission block is provided at the top of the assembly rod, and the transmission block is connected to the transmission groove. By setting the insertion slot and the assembly rod to cooperate, the brush head can achieve rotational cleaning, enhancing the ability of the bristles to cover and clean the details of the pressure needle assembly. The connection between the transmission block and the transmission groove is stable, ensuring that the assembly is not easy to loosen or misalign during rotation. Moreover, the structure of the assembly rod and the insertion slot is standardized and controllable, suitable for mass production and subsequent maintenance.

[0010] As a further description of the above technical solution: the outer circumference of the rotating disk is provided with several auxiliary teeth, and the auxiliary teeth cooperate with the cleaning block. The assembly hole is provided with a threaded groove, and the outer side of the assembly rod is provided with a thread that connects with the threaded groove inside the assembly hole. By setting the auxiliary teeth to cooperate with the cleaning block, the friction of the rotating disk during rotation is increased to prevent slippage. The threaded structure facilitates installation and removal, improves maintenance efficiency, and allows users to replace the cleaning components according to their needs. The threaded cooperation forms a self-locking effect to prevent the structure from loosening due to vibration during equipment operation.

[0011] This utility model has the following beneficial effects:

[0012] This utility model designs a cleaning brush for the indenter assembly. By integrating a handheld component at the bottom of the Shore hardness tester and constructing a collaborative structure between the cleaning component and the rotating component within it, it achieves directional cleaning and efficient transmission of the indenter assembly. The cleaning chamber adopts a tightly enclosed structure, allowing the cleaning brush to be precisely positioned on the surface of the indenter assembly, preventing brush head deviation or sweeping off course, and improving the targeting and safety of the cleaning process. At the same time, in conjunction with the power connection provided by the transmission hole and the rotating component, it realizes the rotational movement of the brush head, enhancing the bristles' ability to cover and clean the surface of the indenter assembly and its crevices, adapting to the needs of removing various contaminant residues. The handle in the handheld component has a flexible rubber grip pad, improving user comfort and reducing hand fatigue caused by prolonged operation. Furthermore, the fixing ring structure enhances the connection rigidity between the cleaning component and the hardness tester body, maintaining the alignment accuracy of the brush head and the indenter assembly, and preventing misalignment or detachment caused by operational vibration.

[0013] The pressure needle assembly cleaning brush designed in this utility model forms a controllable rotation system by setting up standardized mating components such as insertion grooves, assembly rods, and transmission blocks, which improves the stability and efficiency of the transmission process. It also has good batch assembly and maintenance capabilities. The threaded connection between the assembly rod and the assembly hole further enhances the self-locking ability, ensuring that the connection parts are stable and reliable during equipment operation and reducing the risk of loosening due to mechanical vibration or frequent operation. At the same time, the cleaning assembly adopts a split structure, with the cleaning brush and transmission disc precisely connected to the transmission rod through the adapter hole, which facilitates quick disassembly and replacement of different types of brush heads, improving overall maintenance efficiency and adaptability.

[0027] Working principle:

[0028] When using this utility model, the indenter assembly 2 and the cleaning brush are installed on the bottom of the Shore hardness tester 1, with the indenter assembly 2 extending downwards. The cleaning structure is arranged around the indenter assembly 2 to form an integrated positioning cleaning system. After measurement, the user can directly start the cleaning process without disassembling the main structure of the hardness tester. The handheld assembly 3 at the bottom of the hardness tester is fixedly installed on the overall cleaning structure through the cleaning block 31. The cleaning block 31 has a cleaning cavity 32 in the middle, which forms a spatial constraint with the shape of the indenter assembly 2.
