Problems solved by technology

[0003] However, when encountering high-rise buildings such as glass curtain walls and glass ceilings that are inaccessible to personnel, how to break the tempered glass at high places, whether it is trapped people or rescue firefighters, has no way to start; When a fire breaks out, glass breaking at close range may cause damage to glass breaking rescuers
In some special occasions, special equipment such as firearms can be used to break glass, but due to the control of special equipment, it cannot be used in large areas.

Embodiment 1

[0035] Such as Figure 1-Figure 2 As shown, a throwing glass-breaking ball includes a spherical body 1, and protrusions 2 uniformly distributed on the outer surface of the body 1, the hardness of the body 1 and the protrusions 2 are higher than that of tempered glass hardness. The weight of the body 1 is greater than or equal to 1 gram, and the Mohs hardness of the protrusion 2 is greater than or equal to 4.

[0036] figure 2 The protrusions 2 shown in are pyramid structures, all the protrusions 2 have the same size, and the cone angles θ of all the protrusions 2 are greater than or equal to 20 degrees and less than or equal to 160 degrees.

[0037] Preferably, the body 1 and the protrusion 2 have the same hardness, and the body 1 and the protrusion 2 are integrally formed structural parts.

[0038] Preferably, the protrusion 2 is a zirconia-toughened alumina ceramic (ZTA) structure, and the body 1 can also adopt this ceramic structure, wherein the addition ratio can be se...

Embodiment 2

[0041] Such as image 3 As shown, the difference between this embodiment and embodiment 1 is that the body 1 is a cuboid structure.

Embodiment 3

[0043] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the body 1 has a regular octagonal prism structure. On the surface of the body 1, there are a variety of protrusions 2 of different materials, different hardness and different sizes. By optimizing the design of the protrusions 2, a variety of glass breaking balls with different performances are formed to meet the actual glass breaking needs. .

Abstract

The invention discloses a throwing type glass breaking ball, comprising a main body and a plurality of protrusions on the outer surface of the main body; the protrusions are components whose hardnessis higher than that of toughened glass. When the glass breaking operation is needed, the glass breaking ball provided by the invention can be thrown to the toughened glass by hand or by using a device; since the hardness of the protrusions on the glass breaking ball is higher than that of the toughened glass, when the protrusions strike the glass surface, the stress limit on the surface of the toughened glass can be broken, so that the toughened glass can be broken and the purpose of breaking the glass can be realized. when the glass breaking ball provided by the invention is used for glass breaking operation, because of the protrusions on the outer surface of the main body, the glass can be contacted through the sharp parts of the protrusions, and the glass breaking can be realized without great throwing speed; the glass breaking ball has the advantages of high efficiency, slow striking speed, high safety and the like; the glass breaking ball provided by the invention can realize long-distance glass breaking by throwing and realize the safety rescue and rapid rescue of personnel when fire occurs in high-rise buildings and other places requiring glass breaking rescue.

Description

technical field [0001] The invention relates to a glass breaking tool, in particular to a throwing glass breaking ball. Background technique [0002] Tempered glass is widely used in building curtain walls and various vehicles. Due to the high hardness of tempered glass, it is difficult to break the tempered glass after a safety accident, and professional glass breaking tools are required. In daily life, glass-breaking tools can be seen everywhere, and have become one of the important tools to ensure the safety of personnel. For example, on buses, subways and other means of transportation, equipped with safety hammers or automatic glass-breaking devices, the objects of use of such tools are often It is the trapped person himself, and they are all close-contact glass-breaking tools. [0003] However, when encountering high-rise buildings such as glass curtain walls and glass ceilings that are inaccessible to personnel, how to break the tempered glass at high places, whether ...
