Shown in the figure: the pen comprises a pen holder 1, a fixing frame 2, a fixing seat 21, a fixing hole 211, a convex rib 22, a window breaking head 3, a pen cap 4, a protective sleeve 41, a through hole 411, an internal thread 412, a gap 413, a connecting sleeve 42, an external thread 421, a supporting rod 5, a spring 6 and a check ring 7.

Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting features are described in conjunction with the accompanying drawings of the present invention:

as shown in fig. 1-5, the emergency window breaking pen includes a pen holder 1, a fixing frame 2 is fixed on the upper end of the pen holder 1, a window breaking head 3 is fixed on the upper end of the fixing frame 2, a pen cap 4 capable of moving up and down is installed on the upper end of the fixing frame 2, the pen cap 4 covers the window breaking head 3, and a through hole 411 for the window breaking head 3 to extend out is formed on the upper end of the pen cap 4.

As shown in fig. 2 and 4, in order to fix the window breaking head 3, a fixing seat 21 is provided in the upper end of the fixing frame 2, a fixing hole 211 with an upward opening is provided at the upper end of the fixing seat 21, the lower end of the window breaking head 3 is fixed in the fixing hole 211, and a tip provided at the upper end of the window breaking head 3 is exposed out of the fixing hole 211.

As shown in fig. 2, a support rod 5 extending up and down is installed in the pen holder 1, and a spring 6 is installed between the top of the support rod 5 and the bottom of the cap 4. When the cap 4 is pressed down, the spring 6 is compressed. The spring 6 can support the pen cap 4, so that the pen cap 4 is installed stably and is not easy to shake.

As shown in fig. 3, the cap 4 is composed of a sheath 41 and a connecting sleeve 42, the sheath 41 is inserted into the fixing frame 2 from top to bottom, the sheath 41 covers the cap 4, the through hole 411 is formed at the upper end of the sheath 41, the connecting sleeve 42 is accommodated in the fixing frame 2, the lower end of the sheath 41 is fixed with the connecting sleeve 42, and the connecting sleeve 42 is clamped between the top of the spring 6 and the bottom of the fixing base 21.

In order to facilitate the connection between the sheath 41 and the connection sleeve 42, the lower end of the sheath 41 is fixed to the outer wall of the connection sleeve 42 by means of a threaded connection. The lower end of the sheath 41 has an internal thread 412, and the outer wall of the connecting sleeve 42 has an external thread 421 matching with the internal thread 412.

As shown in fig. 4 and 5, two ribs 22 are provided between the inner wall of the fixing frame 2 and the outer wall of the fixing base 21, two notches 413 extending up and down are provided on the outer side of the sheath 41, and the notches 413 are used for the ribs 22 to be clamped in. The inner wall of the fixing frame 2 and the outer wall of the fixing base 21 need to be connected by the convex rib 22, and in order to prevent the convex rib 22 from influencing the up-and-down movement of the sheath 41, a notch 413 needs to be arranged outside the sheath 41.

As shown in fig. 3, the inner wall of the fixing frame 2 is provided with a retaining ring 7, and the retaining ring 7 is positioned below the pen cap 4 and used for retaining the pen cap 4. A gap for the connection sleeve 42 to move up and down is reserved between the check ring 7 and the bottom of the connection sleeve 42, and the check ring 7 is used for preventing the pen cap 4 from being excessively displaced after being normally pressed down so as to prevent the broken window head 3 from pricking hands after penetrating out of the through hole 411 of the pen cap 4.

When the window needs to be broken, the pen cap 4 needs to be pulled down forcibly, the pen cap 4 breaks through the constraint of the retainer ring 7, the pen cap 4 has a large displacement, the window breaking head 3 is exposed, and then the window can be broken.

It should be understood that the above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and that the present invention is not limited by the above description and drawings.
