Description

Technical Field

[0001] The utility model relates to the technical field of emergency fire rescue, in particular to a tempered glass breaking device. Background Art

[0002] Tempered glass has been widely used as automotive glass, curtain walls, doors, and windows due to its high surface compressive stress. However, when encountering accidents such as fire and flood, it is often difficult to break, blocking evacuation routes. Especially on large public transportation such as subways, if the time is delayed, it will cause more casualties.

[0003] The patent with the publication (announcement) number CN208355978U proposes an electric breaking device. Although it can break tempered glass, the breaking grinding head cannot be continuously fixed on the glass during the breaking process, and the stress accumulation and window breaking effect cannot be achieved, which affects the stress size and speed of breaking the glass, and thus affects the breaking efficiency and rescue time.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 2As shown, a tempered glass breaking device includes a handheld rod 1 and a tooth tip support foot 2 that can be inserted into the sealing rubber of the tempered glass. The handheld rod 1 is rotatably connected to the tooth tip support foot 2 through a support foot adjustment mechanism 3. Electric breakers 4 are provided in front and behind the support foot adjustment mechanism 3. The support foot adjustment mechanism 3 is used to adjust the angular position of the tooth tip support foot 2 relative to the electric breaker 4. The tooth tip portion 22 of the tooth tip support foot 2 is used to be inserted into the sealing rubber of the glass, so that the tooth tip support foot 2 and the electric breakers in front or behind are aligned. The glass-breaking grinding heads 42 of the device 4 are in the same plane, and the principle of three-point stability of the plane is used to solve the problems of instability and side slip of the glass-breaking grinding heads 42 during operation. In addition, the hand-held rod 1 is designed to rotate relative to the tooth tip support foot 2, and the tooth tip support foot 2 is used as a fixed point. The principle of mechanical lever is used to make the electric breaker 4 close to the glass, apply sufficient stress to the glass-breaking grinding heads 42, and accelerate stress concentration. When the electric breaker 4 is powered on, the glass-breaking grinding heads 42 rotate rapidly, applying lateral and longitudinal forces to the glass, thereby achieving the purpose of breaking the glass.

[0028] Specifically, the tooth tip support foot 2 includes an upright support portion 21 for connecting the support foot adjustment mechanism 3 and a tooth tip portion 22 arranged transversely relative to the upright support portion 21. The transverse cross-sectional area of ​​the tooth tip portion 22 gradually decreases along the rod tail direction close to the hand-held rod 1. When in use, the sharp corner of the tooth tip portion 22 can be quickly inserted into the sealing rubber, and the remaining part abuts against the glass.

[0029] Specifically, the electric breaker 4 includes a driving motor 41 and a glass breaking grinding head 42 fixedly connected to the output end of the driving motor 41 .

[0030] Furthermore, the present device proposes the following two designs for the connection between the support foot adjustment mechanism 3 and the electric breaker 4 relative to the handheld rod 1;

[0031] Design 1

[0032] like Figures 1 to 2 As shown, the support foot adjustment mechanism 3 includes a pad 33 and two groups of T-shaped support frames 32 constructed in parallel on the base 31. The base 31 is fixedly connected to the upright support portion 21 of the tooth tip support foot 2. A transverse rotating shaft 38 is provided between the T-shaped support frames 32. The hand-held rod 1 and the pad 33 located below the hand-held rod 1 are both mounted on the transverse rotating shaft 38, so as to realize the rotational connection between the hand-held rod 1 and the pad 33 and the T-shaped support frame 32. The two groups of the transverse rotating shafts 38 are connected with anti-slip strips I34 at both ends of the radial direction to prevent the transverse rotating shaft 38 from separating from the T-shaped support frame 32. When the hand-held rod 1 is pressed down, the hand-held rod 1 drives the pad 33 to press against the bolt head 39 on the base 31, so that the hand-held rod 1 can realize the angle adjustment of the electric demolition device 4 relative to the tooth tip support foot 2 with a smaller rotation stroke.

[0033] Specifically, the two groups of electric breakers 4 are respectively fixedly mounted on the head and tail ends of the support arm 35. In this embodiment, the head and tail ends of the support arm 35 are connected with a clamp 351, and the drive motor 41 of the electric breakers 4 is clamped in the clamp 351. The side of the hand-held rod 1 is structured with a limiting column 11, and the support arm 35 is mounted on the transverse rotating shaft 38 of the hand-held rod 1 and is plugged into the limiting column 11 on the hand-held rod 1. The diameter of the limiting column 11 is plugged with an anti-slip strip II, thereby realizing that the support arm 35 is fixedly connected relative to the hand-held rod 1 and can rotate with the hand-held rod 1.

[0034] Design 2

[0035] like Figure 3 As shown, the support leg adjustment mechanism 3 includes a four-way connector 36, the tooth tip support leg 2 is installed in the storage groove on the four-way connector 36 through a rotating shaft, the hand-held rod 1 is arranged through the four-way connector 36, and the head end of the hand-held rod 1 is connected to a lighting lamp. The hand-held rod 1 in front and behind the four-way connector 36 is also provided with a three-way connector 37, and the driving motor 41 of the electric breaker 4 is fixedly connected to the vertical opening of the three-way connector 37; before use, the tooth tip support leg 2 is rotated from the storage groove through the rotating shaft to a state perpendicular to the storage groove.

[0036] Furthermore, the present device also proposes the following two designs for the structure of the handheld rod 1:

[0037] Design 1

[0038] like Figure 3 As shown, the hand-held rod 1 is a telescopic structure, including a sub-rod 15 and a mother rod 16 that are connected in a sleeve manner, and can be adjusted to a suitable length according to the working conditions through a telescopic manner.

[0039] Design 2

[0040] like Figure 4 As shown, the handheld rod 1 includes a plurality of small rods 12 and quick-lock joints 13. The small rods 12 are connected by the quick-lock joints 13, and a fire hammer 14 is installed on the small rod 12 at the tail.

[0041] The two groups of segment rods 12 are connected by a quick-lock joint 13. The length can be adjusted to a suitable length according to the working conditions by increasing or decreasing the number of segment rods 12. The fire hammer 14 on the tail segment rod 12 can also directly break the glass by knocking.

[0042] The working principle and working process of this utility model are as follows:

[0043] Taking design 1 as an example, the tooth tip portion 22 of the tooth tip support foot 2 is inserted into the sealing rubber of the glass, and the hand-held rod 1 is pressed down. The hand-held rod 1 drives the pad 33 to press against the bolt head 39 on the base 31, so that the tooth tip support foot 2 and the glass breaking grinding head 42 of the front or rear electric breaker 4 are in the same plane, and then the glass breaking grinding head 42 is pressed against the glass, and the driving motor 41 drives the glass breaking grinding head 42 to rotate rapidly, applying lateral and longitudinal forces to the glass, thereby achieving the purpose of breaking the glass.

[0044] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
