Description

Technical Field

[0001] This application relates to the technical field of crystal product inspection and testing, and more specifically, to a push-pull force measuring device. Background Technology

[0002] Crystal knobs, due to their unique optical properties, refract and scatter light, producing a dazzling visual effect. Therefore, crystal knobs significantly enhance the overall aesthetics and perceived quality, making devices appear more high-end and luxurious, adding an artistic touch and appeal. At the same time, their elegant appearance complements various design styles, and the high hardness of the crystal material gives it excellent wear resistance, making it less prone to scratches or wear in daily use, thus extending the knob's lifespan.

[0003] Crystal knobs can be fixed by either creating internal threads or using adhesive. In some special cases, creating internal threads is difficult, necessitating adhesive fixation. When using adhesive, selecting a suitable adhesive is crucial for effective fixation, requiring measurement of the required adhesive strength. Currently, there is a lack of equipment on the market specifically for measuring the required adhesive strength of crystal knobs. In practical applications, thrust testing devices designed for other products are typically used (e.g., authorization notice number CN 220751423U, titled "A Grain Thrust Testing Device"). These thrust tests determine the required adhesion for fixing the crystal knob, thus identifying the appropriate adhesive. However, such devices use insertion holes for fixing crystal knobs, which makes the knob prone to displacement under thrust, resulting in unstable installation and inaccurate data.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, rotated 90 degrees, or in other orientations, and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] like Figure 1As shown, the embodiment relates to a push-pull force measuring device, including: a device body 10, a support structure 20, and a pushing structure 30. The device body 10 includes a base 11 and a top cover 12, with one side of the top cover 12 rotatably connected to the corresponding side of the base 11. The support structure 20 includes a first support plate 21, a second support plate 22, a first mounting plate 23, a second mounting plate 24, and a third mounting plate 25. The first support plate 21 and the second support plate 22 are both disposed on the base 11, the first mounting plate 23 is disposed on the first support plate 21, the third mounting plate 25 is disposed on the second support plate 22, and the second mounting plate 24 is movably disposed on the second support plate 22. The pushing structure 30 includes a mounting base 31, a push arm 32, and a force sensor 33. The mounting base 31 is vertically disposed on the first mounting plate 23, the push arm 32 is disposed on the second mounting plate 24, and the push arm 32 corresponds to the mounting base 31. The force sensor 33 is disposed on the side of the push arm 32 away from the mounting base 31.

[0028] In this embodiment, the first support plate 21 supports the first mounting plate 23, the second support plate 22 supports the second mounting plate 24, and the mounting base 31 is vertically mounted on the first mounting plate 23 to fix the crystal glass. The force between the crystal knob and the mounting base 31 simulates the force between the crystal knob and the adhesive, making it less prone to displacement. The push arm 32 is mounted on the second mounting plate 24 and moves synchronously with it. The push arm 32 corresponds to the mounting base 31, and its movement applies a force to the crystal knob. A force sensor 33 is located on the side of the push arm 32 away from the mounting base 31, accurately detecting the force exerted by the push arm 32 on the crystal knob. This embodiment effectively solves the problem of inaccurate testing when performing push force tests on crystal knobs in the prior art.

[0029] It should be noted that a pressure sensor is installed between the crystal knob and the mounting base 31. The pressure sensor can measure the clamping force of the mounting base 31 on the crystal knob. At this time, the pushing force of the push arm 32 is equivalent to the external force that the crystal knob will experience after bonding. When the crystal knob does not shift its position under the push of the push arm 32, it indicates that the external force (i.e., the pushing force) is less than the interaction force between the mounting base 31 and the crystal knob (i.e., the simulated bonding force). Read the data measured by the pressure sensor at this time, and select the corresponding adhesive for bonding to meet the requirements.

[0030] It should also be noted that the push-pull force measuring device also includes a control and analysis module and a display module. The pressure sensor, photoelectric sensor and drive motor 41 are all electrically connected to the control and analysis module, which can transmit the detected data to the control and analysis module, and the display module displays the thrust image, pressure value and displacement value and other related information.

[0031] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting base 31 includes a base plate 311 and a fixing plate 312. The base plate 311 is disposed on the first mounting plate 23, and the fixing plate 312 is disposed on the base plate 311. The fixing plate 312 and the base plate 311 are arranged perpendicularly. The fixing plate 312 has a fixing hole 3121 and an opening 3122, which are connected to the fixing hole 3121. The crystal knob is placed in the fixing hole 3121. The opening 3122 allows the crystal knob to be easily placed into the fixing hole 3121. The fixing plate 312 has a threaded hole that passes through the opening 3122. After the crystal knob is placed, a screw is screwed in for fixation, and the clamping force can be adjusted.

[0032] like Figure 2 and Figure 4 As shown, in some embodiments, the thrust arm 32 has a connecting plate 321, a transition plate 322, an abutment plate 323, and a fixing block 324. The connecting plate 321, the transition plate 322, and the abutment plate 323 are connected sequentially to form a stepped shape. The abutment plate 323 faces the side closest to the mounting base 31. The abutment plate 323 can match the size of the fixing hole 3121 and can effectively abut against the crystal knob. The connecting plate 321 has a slot 3211, and the fixing block 324 is installed in the slot 3211. The fixing block 324 has a mounting groove 3241 for placing the force sensor 33.

[0033] like Figure 2 As shown, in some embodiments, the push-pull force measuring device further includes a drive structure 40, which includes a drive motor 41, a drive screw 42, and a nut seat 43. The drive motor 41 is mounted on the base 11, and the drive screw 42 is connected to the drive motor 41 in a transmission manner. The drive motor 41 provides driving force. The nut seat 43 is movably sleeved on the circumferential outer side of the drive screw 42. The nut seat 43 moves along the axial direction of the drive screw 42 under the rotation of the drive screw 42. The third mounting plate 25 is connected to the nut seat 43, and the third mounting plate 25 moves synchronously with the movement of the nut seat 43.

[0034] like Figure 2As shown, in some embodiments, the second mounting plate 24 is provided with first sliders 241 at both ends facing the base 11, and the second support plate 22 has two sets, which are arranged opposite to each other. Each set of second support plates 22 has a slide rail 221 on one side facing the second mounting plate 24. The two sets of first sliders 241 and the two sets of slide rails 221 are arranged in a one-to-one correspondence. This arrangement makes the second mounting plate 24 more stable during movement.

[0035] like Figure 1 As shown, in some embodiments, the third mounting plate 25 is provided with second sliders 251 at both ends facing the base 11, and the two sets of second sliders 251 and the two sets of slide rails 221 are arranged in a one-to-one correspondence. This arrangement makes the third mounting plate 25 more stable during movement.

[0036] like Figure 2 As shown, in some embodiments, both ends of the two sets of second support plates 22 are provided with limiting protrusions 222, and the first slider 241 and the second slider 251 are provided with limiting blocks that cooperate with the limiting protrusions 222 on their opposite sides. The limiting blocks also abut against the limiting protrusions 222 to limit the movement of the second mounting plate 24 and the third mounting plate 25.

[0037] like Figure 2 As shown, in some embodiments, the drive structure 40 further includes a drive block 44, which is disposed on the third mounting plate 25. The first end of the force sensor 33 is connected to the drive block 44, and the second end of the force sensor 33 is installed in the mounting groove 3241. As the third mounting plate 25 moves, the third mounting plate 25 pushes the force sensor 33 and the fixed block 324 to move synchronously. At this time, the force sensor 33 accurately outputs the magnitude of the thrust of the drive block 44.

[0038] like Figure 2 As shown, in some embodiments, the drive structure 40 further includes a photoelectric sensor disposed on the side of the second mounting plate 24 facing the first mounting plate 23. The photoelectric sensor receives light reflected by the first mounting plate 23, and thereby calculates the moving distance of the second mounting plate 24.

[0039] like Figure 2 As shown, in some embodiments, the drive structure 40 also includes an alarm 45, which is mounted on the base 11 and alarms when an abnormal situation occurs.
