Technical Field

[0001] This invention belongs to the field of protective product technology, specifically relating to an explosion-proof umbrella. Background Technology

[0002] Riot control umbrellas have the sun protection, rain protection, and snow protection functions of ordinary umbrellas, and also have special protective functions (including bulletproof, stabproof, cutproof, gasproof, chemicalproof, etc.) and counterattack methods (electric shock, gas, shooting, etc.).

[0003] For example, Chinese invention patent application number CN201010231129.5, entitled "Bulletproof Umbrella," discloses:

[0004] The canopy (1) is made of a composite three-layer material, and the frame (2) is made of titanium alloy. The canopy (1) includes a bulletproof film (4), a pneumatic fabric (5), and a bulletproof layer (6). On one side of the pneumatic fabric (5), the bulletproof film (4) is bonded with a water-soluble polyvinyl chloride elastic waterproof adhesive, and on the other side of the pneumatic fabric (5), the bulletproof layer (6) is bonded with a waterproof adhesive. These three parts are firmly bonded together to form a composite three-layer material canopy (1). The bulletproof layer (6) is made of titanium alloy metal mesh with a mesh size of 9 mesh / cm. 2 Each mesh contains 2mm ceramic particles, which are corundum, boron carbide, or silicon carbide. The gaps between the ceramic particles and the titanium alloy metal mesh are filled with fiberglass, nylon, or Kevlar.

[0005] However, it only has bulletproof function, is single-function, has a protective layer thickness of more than 2mm, is heavy, difficult to store, and is tiring to use.

[0006] For example, application number CN201410359225.6, entitled "Explosion-proof Umbrella", discloses that the umbrella surface material is selected from at least one of the following polymer materials: Kevlar aramid, polyester, ultra-strong polyethylene, etc., or leather materials such as cowhide, horsehide, pigskin, etc.; the umbrella surface made of the above materials can be inlaid or wrapped with any one or more of the following sheets: ceramic sheets, glass sheets, metal sheets, plastic sheets, etc., on one or both sides.

[0007] It can effectively resist various attacks such as cuts, stabs, and slashes from knives and guns, and even explosions and gunfire, while also featuring a transparent observation window. The patent does not provide specific fabric structure solutions or inlay or wrapping solutions for ceramic, glass, metal, or plastic sheets. Summary of the Invention

[0011] Furthermore, the distance between two adjacent high-strength ceramic sheets is 2 to 3 mm.

[0012] Furthermore, the nonwoven fabric is one of ultra-high molecular weight polyethylene nonwoven fabric, aramid fiber nonwoven fabric, and composite fiber nonwoven fabric.

[0013] Furthermore, the non-woven fabric layer comprises 5 to 10 layers of non-woven fabric.

[0014] Furthermore, the thickness of each layer of the non-woven fabric is 0.1 to 0.2 mm, the thickness of the high-strength ceramic sheet is 1 mm, the diameter is 2 to 3 mm, and a 0.5 mm circular hole is provided in the middle of the high-strength ceramic sheet.

[0015] Preferably, the high-strength ceramic sheet is one or more of alumina, silicon carbide, or boron nitride.

[0016] Furthermore, the umbrella ribs and central column are made of carbon fiber, the sutures are made of aramid fiber, and the bone grooves and connectors are made of titanium alloy.

[0017] Furthermore, the central column has a hollow structure, and the endoscope is 6–12 mm in diameter and 10–16 mm in outer diameter.

[0018] Beneficial effects:

[0019] This invention has an ordinary appearance, is rainproof and UV resistant, and can withstand acids, alkalis and various liquids, while also having excellent concealment.

[0020] This invention achieves high strength by increasing the wall thickness of the central column.

[0021] This invention combines 5 to 10 layers of non-woven fabric by sewing, avoiding the non-woven fabric from forming a whole while ensuring its effective bonding. In addition, a 1mm thick high-strength ceramic piece is sewn onto the 0.5 to 1mm thick non-woven fabric, thereby reducing the weight of the fabric while ensuring protective function and storage.

[0029] Example 1

[0030] refer to Figures 1-6 An explosion-proof umbrella includes an umbrella canopy 1, an umbrella handle 6, umbrella ribs 4, a central post 2, an umbrella tail 3, and umbrella straps 5. The umbrella canopy 1 includes an outer layer, a protective layer, and an inner layer arranged sequentially from the outside to the inside. The outer layer, the protective layer, and the inner layer are sewn together to form an integral structure.

[0031] This invention has an ordinary appearance, is rainproof and UV resistant, and can withstand acids, alkalis and various liquids, while also having excellent concealment.

[0032] In this embodiment, the fire resistance of the explosion-proof umbrella of the present invention is at least 1 minute;

[0033] In this embodiment, the surface layer is made of polyester; the protective layer includes a non-woven fabric layer made of multiple layers of non-woven fabric and multiple high-strength ceramic pieces sewn onto the non-woven fabric layer, the multiple high-strength ceramic pieces being arranged in a matrix, and the bottom layer is made of polyester.

[0034] In this embodiment, the ceramic is fixed to the non-woven fabric by stitching. The high-strength ceramic sheet can deform and slow down the high-speed bullet, and at the same time, it will break and absorb energy when the bullet hits. The bottom non-woven fabric can continue to absorb the bullet's energy, thereby effectively reducing the bullet's speed.

[0035] In practice, the initial velocity of the Type 95 pistol bullet is 300 m / s. After passing through the ceramic disc and non-woven fabric, the velocity drops to 0-30 m / s, thus achieving the purpose of protection.

[0036] In this embodiment, the distance between two adjacent high-strength ceramic sheets is 2 to 3 mm.

[0037] In this embodiment, the non-woven fabric is one of the following: ultra-high molecular weight polyethylene non-woven fabric, aramid fiber non-woven fabric, and composite fiber non-woven fabric.

[0038] In this embodiment, the non-woven fabric layer includes 5 to 10 layers of non-woven fabric.

[0039] In this embodiment, the thickness of each layer of non-woven fabric is 0.1 to 0.2 mm, the thickness of the high-strength ceramic sheet is 1 mm, the diameter is 2 to 3 mm, and a 0.5 mm circular hole is provided in the middle of the high-strength ceramic sheet.

[0040] This invention combines 5 to 10 layers of non-woven fabric by sewing, avoiding the non-woven fabric from forming a whole while ensuring its effective bonding. Furthermore, a 1mm thick high-strength ceramic sheet is sewn onto the 0.5 to 2mm thick multi-layer non-woven fabric, thereby reducing the weight of the fabric while ensuring protective function and storage capacity. It is bulletproof, puncture-proof, impact-resistant, lightweight, and easy to carry.

[0041] In this embodiment, the umbrella rib 4 and the central column 2 are made of carbon fiber, the suture is made of aramid fiber, and the bone groove and connector are made of titanium alloy by machining.

[0042] In practice, to reduce the number of weak seams in the protective layer, the fabric is cut into a single tapered piece and sewn together to form the umbrella surface.

[0043] In this embodiment, the non-woven fabric is sewn together to form a whole. When the thickness of the non-woven fabric is 0.5 to 2 mm, it can achieve uniform stress while having good softness, making it easy to store and fold.

[0044] In this embodiment, the central column 2 is a hollow structure with an inner diameter of 6-12 mm and an outer diameter of 10-16 mm.

[0045] This invention achieves high strength by increasing the wall thickness of the central column.

[0046] The above are merely preferred embodiments of the present invention and do not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
