[0005] In response to the shortcomings of the existing technology, the utility model provides a puncture test device for motorcycle helmet processing, which solves the problem that the puncture test machines previously used for helmet processing mostly perform real-time detection on a single group of helmets. After the detection is completed, the original fixed helmets need to be removed, which is inefficient. In addition, the helmets are clamped by hydraulic push rods, which leads to a high overall cost of the device.

Second sliders are fixed at both ends of the magnetic plate, and the second sliders slide up and down along the vertical slide grooves provided on the door frame.

[0013] Preferably, an inner clamping rod is fixed to the top end of each of the first sliders, and the cross-sections of the first slider and the second slider are both T-shaped structures.

[0014] Beneficial effects

[0015] The utility model provides a puncture test device for motorcycle helmet processing. Compared with the existing technology, it has the following advantages:

[0016] (1) The puncture test device for processing motorcycle helmets is designed with an inner clamping assembly. Since the rotating shaft is screwed to the cross base block, according to the principle of screw transmission, the rotation of the rotating shaft will be converted into the up and down movement of the cross base block. The sliding groove design on the L-shaped rod allows the first slider to slide freely in the horizontal direction, so that the connecting block can drive the connecting rod to move, thereby allowing multiple groups of inner clamping rods to extend outward, and then complete the external support clamping on the inside of the motorcycle helmet. This design can flexibly adjust the position to accommodate the clamping of helmets of different sizes. Since there are multiple groups of inner clamping assemblies, multiple motorcycle helmets can be clamped at the same time, and then cooperate with the puncture test tool above to perform efficient testing.

[0017] (2) The puncture test device for processing motorcycle helmets has a driving component designed in which four groups of L-shaped rods are fixedly installed on the upper end of the base, providing a stable support structure for the entire inner clamp component. When the helmet needs to be punctured, the rotating rod is manually rotated to rotate inside the base, driving the worm welded on it to rotate. At the same time, the worm wheel engaged with the worm wheel rotates accordingly. The worm wheel is welded to the rotating shaft, so the rotating shaft also starts to rotate, which can provide driving force for multiple groups of inner clamp components at the same time. It is simple and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In this embodiment, the driving assembly 22 includes a rotating rod 221 rotatably mounted inside the base 1, and several groups of worms 222 are welded on the rotating rod 221. A rotating shaft 223 is rotatably arranged inside the base 1, and the rotating shaft 223 passes through the cross base block 214 and is threadedly screwed thereto, and a worm wheel 224 meshing with the worm 222 is welded on the rotating shaft 223; the rotating rod 221 is rotated to rotate inside the base 1, driving the worm 222 welded thereon to rotate, and the worm wheel 224 meshing with the worm 222 rotates accordingly, and the worm wheel 224 is welded on the rotating shaft 223, so the rotating shaft 223 also starts to rotate. Since the rotating shaft 223 is threadedly screwed to the cross base block 214, according to the principle of thread transmission, the rotation of the rotating shaft 223 will be converted into the up and down movement of the cross base block 214.

[0026] When the power switch is turned off, the magnetic plate 8 falls down from a height, and the second sliders 10 at both ends of the magnetic plate 8 slide up and down along the vertical slide groove provided on the gate frame 4.

[0027] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] During operation, first, four groups of L-shaped rods 211 are fixedly installed on the upper end of the base 1 to provide a stable support structure for the entire inner clamp assembly. When the helmet needs to be punctured, the rotating rod 221 is manually rotated to rotate inside the base 1, driving the worm 222 welded thereon to rotate. At the same time, the worm wheel 224 engaged with the worm 222 rotates accordingly. The worm wheel 224 is welded to the rotating shaft 223, so the rotating shaft 223 also starts to rotate. Since the rotating shaft 223 is threadedly connected to the cross base block 214, according to the principle of thread transmission, the rotation of the rotating shaft 223 will be converted into the up and down movement of the cross base block 214. The sliding groove design on the L-shaped rod 211 allows the first slider 212 to slide freely in the horizontal direction, so that the connecting block 213 can drive the connecting rod 215 to move, thereby Multiple groups of inner clamping rods 216 extend outward, and then complete the external support clamping on the inner side of the motorcycle helmet.
