Abstract
Description
Technical Field
[0001] This utility model relates to the field of bulletproof vest technology, specifically to an anti-dent composite fiber bulletproof vest. Background Technology
[0002] As a core piece of personal protective equipment, bulletproof vests directly impact the user's safety through their protective performance and durability. With advancements in materials technology, composite fibers (such as ultra-high molecular weight polyethylene fiber and aramid fiber) have become the mainstream material for bulletproof vests due to their advantages such as high strength, low density, and strong impact resistance.
[0003] However, traditional composite fiber bulletproof vests mostly adopt a one-piece sewn structure, where multiple layers of composite fiber fabric are cut as a whole and fixed inside the vest cover with needle and thread or hot melt adhesive to form an inseparable, integral bulletproof unit. In actual use, bulletproof vests are prone to localized impacts (such as impacts from training darts or scratches from sharp objects), causing localized breakage and deformation of the composite fiber layers, or localized fiber aging due to long-term wear. In such cases, even if only a small area is damaged, the entire bulletproof vest must be discarded, and the composite fiber material in the undamaged areas cannot be reused, resulting in material waste. Utility Model Content
[0004] In view of the problems existing in the current anti-dent composite fiber bulletproof vest, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide an anti-dent composite fiber bulletproof vest, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A dent-resistant composite fiber bulletproof vest includes an upper part and a lower part, which are arranged sequentially from top to bottom. The upper and lower parts are fixedly connected on their adjacent sides by a connecting strap. A through groove is provided in the middle of the lower part of the vest. Multiple rotating shells are arranged sequentially from left to right inside the through groove. Composite fiber strips are snapped into the inside of each rotating shell. A rotating block is fixedly provided on the lower side of each rotating shell. A rotating rod is fixedly sleeved in the middle of each rotating block. Connecting blocks are rotatably connected to both ends of the rotating rod. The lower side of each connecting block is fixedly connected to the inner wall of the through groove. An L-shaped plate is fixedly provided on the upper inner wall of the through groove at a position corresponding to the rotating shell. The upper side of the rotating shell abuts against the inner wall of the L-shaped plate. Limiting mechanisms that restrict the rotation of the rotating shells are provided on both sides of the upper part of the vest.
[0008] Preferably, the limiting mechanism includes mounting blocks and retaining rings. Two mounting blocks are fixedly disposed on both sides of the upper part of the bulletproof vest. The retaining ring is movably sleeved on the outer side of the lower part of the bulletproof vest. The inner wall of the retaining ring abuts against the side of the plurality of rotating shells away from the L-shaped plate. An internally threaded tube is rotatably disposed on the lower side of the mounting block. A threaded rod is threaded inside the internally threaded tube. The lower end of the threaded rod is fixedly connected to the retaining ring.
[0009] Preferably, a knob is fixedly sleeved on the outer wall of the internally threaded tube.
[0010] Preferably, weight-reducing grooves are provided on both the front and rear sides of the rotating shell.
[0011] Preferably, both the rotating shell and the composite fiber strip have rectangular cross-sections, and the outer wall of the composite fiber strip abuts against the inner wall of the rotating shell.
[0012] Preferably, the top of the rotating shell has an opening.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] This invention utilizes the simultaneous rotation of the internally threaded tubes on both sides to move the threaded rods relative to the internally threaded tubes, thereby moving the retaining ring and separating it from multiple rotating shells. This releases the restriction on the rotating shells. Then, by rotating the rotating shells around the rotating rods as axes, the openings of the rotating shells are exposed, allowing the composite fiber strips to be extracted from them. This means that when the composite fiber strips in a certain area are damaged due to impact or wear, only the composite fiber strips in that area need to be replaced, without discarding the entire bulletproof vest.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] This utility model discloses an anti-dent composite fiber bulletproof vest.
[0023] Example 1
[0024] Reference Figure 1-3 A dent-resistant composite fiber bulletproof vest includes an upper part 1 and a lower part 2, arranged sequentially from top to bottom. The upper part 1 and the lower part 2 are fixedly connected on their closest sides by a connecting strap 12. A through groove is formed in the middle of the lower part 2, and multiple rotating shells 6 are arranged sequentially from left to right inside the through groove. Composite fiber strips 7 are snapped into the interior of each rotating shell 6. Weight-reducing grooves are formed on both the front and rear sides of each rotating shell 6 to reduce its weight. Both the rotating shell 6 and the composite fiber strips 7 have rectangular cross-sections. The outer wall of the composite fiber strips 7 is flush with the rotating shell 6. The inner walls abut against each other, preventing the composite fiber strip 7 from rotating relative to the rotating shell 6. The top of the rotating shell 6 has an opening to facilitate the removal of the composite fiber strip 7 that needs to be replaced. A rotating block 4 is fixedly installed on the lower side of the rotating shell 6. A rotating rod 5 is fixedly sleeved in the middle of the rotating block 4. Both ends of the rotating rod 5 are rotatably connected to connecting blocks 3. The lower side of the connecting block 3 is fixedly connected to the inner wall of the through groove. An L-shaped plate 13 is fixedly installed on the upper inner wall of the through groove at a position corresponding to the rotating shell 6. The upper side of the rotating shell 6 abuts against the inner wall of the L-shaped plate 13. Limiting mechanisms that restrict the rotation of the rotating shell 6 are provided on both sides of the upper part 1 of the bulletproof vest.
[0025] Example 2
[0026] Reference Figure 1-3 The limiting mechanism includes mounting blocks 8 and retaining rings 11. Two mounting blocks 8 are fixedly installed on both sides of the upper part 1 of the bulletproof vest. The retaining rings 11 are movably sleeved on the outer side of the lower part 2 of the bulletproof vest. The inner wall of the retaining rings 11 abuts against the side of the multiple rotating shells 6 away from the L-shaped plate 13. An internally threaded tube 9 is rotatably installed on the lower side of the mounting blocks 8. A threaded rod 10 is threaded inside the internally threaded tube 9. The lower end of the threaded rod 10 is fixedly connected to the retaining ring 11. A knob is fixedly sleeved on the outer wall of the internally threaded tube 9 to facilitate the rotation of the internally threaded tube 9.
[0027] In this invention, when replacing the damaged composite fiber strip 7, the internal threaded tubes 9 on both sides are rotated simultaneously, causing the threaded rods 10 on both sides to move relative to the internal threaded tubes 9. This moves the retaining ring 11, causing it to separate from the multiple rotating shells 6, thus releasing the restriction on the rotating shells 6. Then, the rotating shells 6 are rotated around the rotating rod 5 as an axis, exposing the opening of the rotating shells 6. At this point, the composite fiber strip 7 can be pulled out from the rotating shells 6. Therefore, when the composite fiber strip 7 in a certain area is damaged due to impact or wear, only the composite fiber strip 7 corresponding to that area needs to be replaced, without discarding the entire bulletproof vest.
[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
