Description

Technical Field

[0002] Velcro, also known as hook and loop fasteners or snap fasteners, is a widely used connecting material. It consists of two paired strips of different materials. One side is fine and soft fibers, and the other side is harder bristles with hooks. When the two are combined, the bristles will pull the fibers, thereby bonding the two items together. Velcro has the characteristics of easy use, durability, reusability and flexible adjustment. Therefore, it is widely used in various fields. However, the life of Velcro is usually affected by various factors, so a Velcro life detection mechanism is needed.

[0003] There is currently a Velcro life detection device (Announcement No.: CN215414968U), which includes: a fixing component for fixing the first adhesive portion of the Velcro; a clamping component for fixing the second adhesive portion of the Velcro that cooperates with the first adhesive portion; and a driving mechanism connected to the clamping component, which is used to drive the clamping component to perform reciprocating linear motion so that the second adhesive portion rolls relative to the first adhesive portion. According to the Velcro life detection device of the utility model, the Velcro can be connected and separated by the driving mechanism driving the clamping component to perform linear motion, causing part of the clamping component to roll on the surface of the fixing component. This eliminates the need for technicians to frequently connect or separate the Velcro, prevents manual operation from affecting the test results, improves the accuracy of the test structure, and saves manpower and improves test efficiency.

[0026] like Figure 4 and Figure 7 As shown, the four corners of the bottom end of the dust shield transparent box 2 are fixedly installed with plug-in blocks 10 with plug-in holes, and the plug-in slots 5 are evenly distributed at the four corners of the upper surface of the detection support base plate 1. The plug-in blocks 10 are plugged into the plug-in slots 5. A spring slot is provided on one side of the inner wall of the plug-in slot 5. The fixing assembly 6 includes a clamping spring 601, which is fixedly installed in the spring slot. A clamping wedge block 602 is fixedly installed at one end of the clamping spring 601. The clamping wedge block 602 is fixedly installed at one end of the clamping spring 601. 02 and the plug-in holes in the plug-in block 10 are slidably engaged with each other, so that when the staff fixes the dust-shielding transparent box 2, the staff will plug the plug-in blocks 10 at the four corners of the bottom end of the dust-shielding transparent box 2 into the plug-in slots 5 on the upper surface of the detection support base plate 1. At this time, the spring force of the clamping spring 601 on the clamping wedge block 602 can enable the clamping wedge block 602 to limit the plug-in block 10, thereby completing the fixed limit of the dust-shielding transparent box 2.

[0027] like Figure 4 and Figure 5As shown, the driving ring 701 in the linear driving assembly 7 is rotatably mounted on the upper surface of one end of the detection support frame 3, and a hub motor 706 is embedded in the driving ring 701. The lower output end of the hub motor 706 and the upper surface of the detection support frame 3 are fixedly connected to each other, and an active rod 707 is fixedly mounted on the circumferential outer wall of the driving ring 701. A driven rod 708 is rotatably mounted on one end of the active rod 707. The concave plate 702 is fixedly mounted on the upper surface of one end of the detection support frame 3, and the sliding block 703 is slidably engaged in the concave plate 702. One end of the driven rod 708 is rotatably connected to the outer wall of one side of the upper end of the sliding block 703, and the fixed rod 708 is inserted into the sliding block 703.

One end of the torsion spring 710 is fixedly connected to one side surface of the fixed frame 704, and one end of the Velcro hook surface 8 wrapped around the outer surface of the driving cylinder 705 is fixed to the upper end side surface of the detection support frame 3 through the mounting plate 11.

The turning on of the hub motor 706 can enable the driving ring 701 to drive the active rod 707 to move, and then with the movement of the active rod 707, the driven rod 708 can push the sliding block 703 to slide horizontally in the concave plate 702. At this time, the driving cylinder 705 with the Velcro hook surface 8 on the outer surface starts to rotate, thereby being able to connect the Velcro hook surface 8 with the Velcro hair at the top of the dust shield transparent box 2 The surface 13 gradually fits together, and the torsion spring 710 begins to shrink. When the hub motor 706 rotates to a certain angle, the sliding block 703 begins to slide in the opposite direction in the concave plate 702. At this time, the torsion spring 710 begins to return to its original position, and then it can drive the driving cylinder 705 to reverse, so that the Velcro hook surface 8 and the Velcro fur surface 13 are separated. When the hub motor 706 drives the driving ring 701 to rotate continuously, the Velcro hook surface 8 and the Velcro fur surface 13 begin to stick and separate regularly, which facilitates the detection of the life of the Velcro. When dust gases of different concentrations are introduced through the dust valve 9, the influence of different concentrations of dust on the life of the Velcro can be obtained.
