Description

Technical Field

[0001] The utility model relates to a curtain, in particular to a bulletproof curtain. Background Art

[0002] In existing offices or homes, curtains are usually installed by the windows to block light or keep out the cold. There are many styles of curtains now, including curtains that are pulled open to both sides and roller blinds that are pulled up and down. The functions of current curtains are generally to block light or have heat insulation and UV protection. The fabrics of the curtains pulled open from both sides are generally the same, so the functions they achieve are also very simple. However, people now have more and more requirements for the use of curtains. Therefore, traditional single roller curtains obviously cannot meet people's different usage needs. As people pay more attention to safety, some bullets or high-impact fragments will rush into the room, affecting personal safety, so it is necessary to effectively prevent these accidental injuries. Summary of the invention

[0003] The utility model provides a bulletproof curtain with a simple structure, which can transmit light to meet the normal use of curtains and also has a bulletproof effect and high safety; it solves the technical problem that the curtains in the prior art can only block light but cannot effectively prevent large external impact forces and protect personal safety.

[0004] The above technical problem of the utility model is solved by the following technical solution: a bulletproof curtain, comprising a curtain, wherein the curtain comprises staggered flexible buffering light-transmitting curtain pieces and bulletproof curtain pieces, wherein the bulletproof curtain pieces contain at least one bulletproof layer; when the curtain is unfolded, the flexible buffering light-transmitting curtain pieces allow light to penetrate, and when the curtain is folded, the bulletproof curtain pieces overlap to form a plane to form a bulletproof surface, and the flexible buffering curtain pieces form an arc buffer surface. The flexible buffering light-transmitting curtain pieces of the curtain can realize the traditional light-transmitting function, and the bulletproof curtain can realize the shading function, and at the same time, since at least one bulletproof layer is arranged inside, the protective function can still be realized. The two sides of the flexible buffering light-transmitting curtain pieces are connected to the bulletproof curtain, which can not only connect the bulletproof curtain together, but also provide a certain buffer for the impact of bullets or fragments, convert the impact potential energy into the kinetic energy of the curtain, and improve safety. Allow users to stay indoors with peace of mind. At the same time, the cost will not increase a lot, which is much cheaper than the price of installing bulletproof glass, etc., and is suitable for most people.

[0005] Preferably, the flexible buffer light-transmitting curtain pieces and the bulletproof curtain pieces are arranged vertically, so that the light-transmitting effect is better and more uniform.

[0006] Preferably, the upper end of the bulletproof curtain piece is fixed on an upper fixing piece, and the upper fixing piece includes a rotating piece, the rotating piece is fixed on one end of the bulletproof curtain piece, and the other end of the rotating piece is fixed on a pulley frame, and the pulley frame is located in the guide rail. The bulletproof curtain piece has a certain hardness, and by driving the rotating piece to rotate and slide in the guide rail, the bulletproof curtain piece is superimposed with the adjacent flexible buffering light-transmitting curtain piece, and an arc transition is formed at the junction of the flexible buffering light-transmitting curtain piece and the bulletproof curtain piece. At the same time, when the bulletproof curtain piece is impacted, the flexible buffering light-transmitting curtain piece can form a buffer and absorb energy, thereby improving the bulletproof effect.

[0007] Preferably, a counterweight is provided at the lower end of the bulletproof curtain, and the mass of the counterweight is the bottom plate installed at the bottom end of the curtain. The counterweight is the bottom bar installed at the bottom end of the curtain, and the kinetic energy of the bullet or fragment is converted into the deformation of the curtain and the accelerated motion of the bottom bar. The weight of the bottom bar is determined by the energy of the bullet or fragment and the number of the cloth and the bottom bar.

[0008] Preferably, the bulletproof layer is made of ultra-high molecular weight polyethylene fiber material or aromatic polyamide organic fiber material.

[0009] Preferably, when the curtain fabric is folded, the flexible buffering light-transmitting curtain piece is folded behind the bulletproof curtain piece.

[0010] Preferably, the curtain is provided with a bulletproof curtain cavity, in which a bulletproof curtain with a multi-layer structure is placed, and bulletproof layers of different thicknesses and numbers are filled as required to meet the bulletproof effect.

[0011] Therefore, a bulletproof curtain of the utility model has the following advantages: simple structure, folding is formed by rotating the angle of the bulletproof curtain pieces to achieve the effects of shading and bulletproofing; the flexible buffering and light-transmitting curtain pieces are located between two adjacent bulletproof curtain pieces, which can play the role of light transmission, connection and buffering energy absorption; the number of bulletproof layers can be adjusted according to different usage requirements; the design of the counterweight block improves the bulletproof effect.

[0014] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0015] Example:

[0016] like Figure 1 and 2As shown, a bulletproof curtain comprises an upper frame 1, wherein a curtain fixing and mounting device is arranged in the upper frame 1. The curtain is mounted on a wall or a window frame through the upper frame 1.

[0017] The curtain fabric includes staggered flexible buffering light-transmitting curtain pieces 4 and bulletproof curtain pieces 3, and the flexible buffering light-transmitting curtain pieces 4 and the bulletproof curtain pieces 3 are arranged vertically. The flexible buffering light-transmitting curtain pieces 4 have good light transmittance and strong flexibility. The bulletproof curtain pieces 3 include at least one bulletproof layer. A bulletproof curtain cavity is formed on the curtain fabric, and at least one bulletproof layer is filled in the bulletproof curtain cavity, and the bulletproof layer is made of ultra-high molecular weight polyethylene fiber material.

[0018] The upper end of the bulletproof curtain piece 3 is fixed on the rotating member 2, and the lower end of the bulletproof curtain piece 3 is fixed on the bottom plate 8. The rotating member 2 is installed on the pulley frame 7, and the pulley frame 7 can move on the guide rail 6 in the guide rail frame 3 through the pulley, and the guide rail frame 3 is located in the upper frame 1. The rotation of the rotating member 2 can drive the bulletproof curtain piece 3 to rotate. When shading or bulletproofing is required, the bulletproof curtain piece 3 is rotated by operating the rotating member 2, and the flexible buffering light-transmitting curtain piece 4 is folded to the rear side of the bulletproof curtain piece 3. The flexible buffering light-transmitting curtain piece 4 and the bulletproof curtain piece form an S-shaped folding connection. The flexible buffering light-transmitting curtain piece 4 located between the two bulletproof curtain pieces 3 forms a flexible connection, thereby playing an energy-absorbing and buffering effect on the impact of bullets or fragments.
