Description

Technical Field

[0001] This utility model belongs to the field of Shore hardness testers, and specifically relates to a pressure-visualized Shore hardness tester. Background Technology

[0002] In the research, testing, and production processes of industries such as chemical engineering, machinery manufacturing, and building materials, Shore hardness testers are widely used to measure the hardness of various materials. Type A (flat-tipped stylus) Shore hardness testers are mainly used to measure soft materials such as soft rubber, soft plastics, polyesters, leather, and wax. Type D (pointed-tipped stylus) Shore hardness testers are used to measure hard materials such as hard plastics, glass, and vulcanized rubber. Type C (round-tipped stylus) is suitable for measuring microporous materials made of rubber and plastics containing foaming agents. With technological advancements, soft silicone thermally conductive gels with extremely low hardness have been widely used. However, traditional Shore hardness testers have rigid styluses, which, when measuring ultra-soft materials (such as silicone thermally conductive gels), can easily lead to uneven force application, resulting in insufficient material penetration or contact, affecting measurement accuracy. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a pressure-visualized Shore hardness tester.

[0004] To achieve the above and other related objectives, this utility model provides a pressure-visualized Shore hardness tester. The hardness tester includes a dial, a pressure block disposed on the top of the dial, an adjustment knob disposed on the side of the dial, a sleeve disposed on the bottom of the dial and communicating with the interior of the dial, a probe movably disposed in the sleeve, a probe disposed at the bottom end of the probe and able to pass through the bottom end of the sleeve, and a spring sleeved on the probe. A spherical silicone is fixedly disposed outside the probe, and the outer surface of the silicone has a plurality of honeycomb-shaped concave holes.

[0005] Optionally, a stop plate for stopping the bottom of the spring is fixed at the bottom of the probe, and a damper parallel to the spring is provided between the stop plate and the top wall of the sleeve.

[0006] Optionally, the bottom wall of the sleeve is provided with a through hole through which the probe can pass, and the diameter of the through hole is smaller than the diameter of the stop plate.

[0007] Optionally, the stop plate is provided with a pressure sensor that abuts against the second end of the spring and is used to detect the pressure value, and the dial is also provided with a pressure indicator that is electrically connected to the pressure sensor.

[0008] Optionally, the spherical silicone is a hemispherical silicone, the bottom of the probe is hemispherical, and the spherical silicone is bonded to the surface of the probe.

[0009] As described above, the pressure-visualized Shore hardness tester of this invention has the following beneficial effects: When using the pressure-visualized Shore hardness tester of this invention to test the hardness of silicone thermally conductive gel, the spherical silicone on the probe is brought into contact with the silicone thermally conductive gel. Relying on the contact between the spherical silicone and the surface of the silicone thermally conductive gel, the probe can be prevented from penetrating the silicone thermally conductive gel during the application of force. By setting multiple honeycomb-shaped concave holes, the contact area between the probe and the silicone thermally conductive gel can be increased, avoiding the surface of the silicone thermally conductive gel from being indented due to the pressure of the probe, thus improving the accuracy of the measurement.

[0012] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. For ease of explanation, when detailing the embodiments of this utility model, the cross-sectional views showing the device structure may be partially enlarged without adhering to the general scale, and the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. Furthermore, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0013] For ease of description, spatial relation terms such as “below,” “under,” “lower than,” “below,” “above,” and “upper” may be used herein to describe the relationship between one element or feature shown in the accompanying drawings and other elements or features. It will be understood that these spatial relation terms are intended to include directions other than those depicted in the drawings for devices in use or operation. Furthermore, when a layer is referred to as being “between” two layers, it may be the only layer between the two layers, or there may be one or more layers in between.

[0014] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show components related to this utility model and are not drawn according to the actual number, shape, and size of the components in the actual implementation. In the actual implementation, the form, quantity, and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex. To keep the illustrations as concise as possible, not all structures are indicated in the drawings.

[0015] like Figure 1 , 2 As shown, this embodiment provides a pressure-visualized Shore hardness tester. The hardness tester 10 includes a dial 11, a pressure block 12 disposed on the top of the dial 11, an adjustment knob 13 disposed on the side of the dial 11, a sleeve 14 disposed on the bottom of the dial 11 and communicating with the interior of the dial 11, a probe 15 movably disposed in the sleeve 14, a probe 16 disposed at the bottom end of the probe 15 and able to pass through the bottom end of the sleeve 14, and a spring 17 sleeved on the probe 15. A spherical silicone 18 is fixedly disposed on the probe 16 to cover the probe 16, and the outer surface of the silicone 18 is provided with a plurality of honeycomb-shaped concave holes 19.

[0016] Using the pressure-visualized Shore hardness timer of this invention, when testing the hardness of silicone thermally conductive gel, the spherical silicone 18 on the probe 16 is brought into contact with the silicone thermally conductive gel. Relying on the contact between the spherical silicone 18 and the surface of the silicone thermally conductive gel, the probe 16 can be prevented from penetrating the silicone thermally conductive gel during the application of force. By setting multiple honeycomb-shaped concave holes 19, the contact area between the probe 16 and the silicone thermally conductive gel can be increased, avoiding the surface of the silicone thermally conductive gel from being indented due to the pressure of the probe, thus improving the accuracy of the measurement.

[0017] Furthermore, a stop plate 20 for stopping the bottom of the stop spring 17 is fixedly provided at the bottom of the probe 15, and a damper 21 arranged parallel to the spring 17 is also provided between the stop plate 20 and the top wall of the sleeve 14.

[0018] A linear spring 17 and a damper 21 are connected in parallel to form a two-stage buffer system of spring 17-damping. When the probe 15 is pressed down, the spring 17 compresses and absorbs the impact force, and the damper 21 suppresses the rebound vibration, ensuring that the probe makes smooth contact with the sample.

[0019] Specifically, the bottom wall of the sleeve 14 is provided with a through hole through which the probe 16 can pass, and the diameter of the through hole is smaller than the diameter of the stop plate 20.

[0020] Furthermore, the stop plate 20 is provided with a pressure sensor that abuts against the second end of the spring 17 and is used to detect the pressure value, and the dial 11 is also provided with a pressure indicator that is electrically connected to the pressure sensor.

[0021] During the testing process, a pressure sensor detects the pressure applied by the user and displays it on a pressure indicator. When the pressure applied by the user falls within a certain range, it indicates that the applied pressure is reasonable, and the accuracy of the measured material hardness is high. However, when the applied force is too large or too small, the accuracy of the measured material hardness will deviate.

[0022] Specifically, the spherical silicone 18 is a hemispherical silicone, the bottom of the probe 16 is hemispherical, and the spherical silicone 18 is bonded to the surface of the probe 16.

[0023] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
