Breaking device

Abstract

An improved breaking device, which has a base, a breaking bolt, an elastic element and a conical head, wherein, the base connects to the body at one end, the conical head is linked with the base and the elastic element and breaking bolt are installed in the conical head. Therefore, the breaking device with the above-mentioned elements is used in combination with baton and breaker to smash windows, and yet, when the breaking device is not used for this purpose, the breaking bolt is hidden in the conical head to avoid scratching any persons or articles and ensure user safety.

Claims

1. A breaking device comprising: a base having a first binding site at one end thereof, said base having a registration site at an opposite end of said base, said registration site having a sliding section and a first limit section at said opposite end of said base; a body joined to said first binding site of said base; a breaking bolt having a sharp conical tip at one end thereof, an opposite end of said breaking bolt bearing against said opposite end of said base; a conical head having a conical surface at an outer end thereof, said conical head having a hole formed centrally of said conical surface, said conical head having a holding hole formed therein, said conical head having a second limit section formed at an opposite end thereof, said second limit section defining an opening at an opposite end of said conical head, said sliding section of said base extending through said opening such that said first limit section of said base resides in said holding hole, said first limit section having a diameter greater than a diameter of said opening, said breaking bolt residing entirely within said holding hole of said conical head, said sharp conical tip facing said hole in said conical surface; and an elastic element bearing against a retainer lip at said opposite end of said breaking bolt so as to urge said breaking bolt away from said hole of said conical surface, a movement of said bolt in a direction towards said conical head causing said breaking bolt to move toward and through said hole of said conical surface of said conical head.

2. The breaking device of claim 1, said first binding site having a first thread section, said body having a second binding site, said second binding site having a second thread section, said first thread section engaged with said second thread section.

3. The breaking device of claim 1, said body being a baton.

4. The breaking device of claim 1, said body being a breaker grip.

DETAILED DESCRIPTION OF THE INVENTION

(7) As shown in FIGS. 2 to 4, the breaking device A of the present invention is comprised of a base 1, a breaking bolt 2, an elastic element 3 and a conical head 4.

(8) The base 1 has the first binding site 11 on one end, a body B combined with the first binding site 11, a registration site 12 on the other end of the base 1, the registration site 12 having a sliding section 121 and the first limit section 122.

(9) The breaking bolt 2 has a sharp conical tip 21 on the front end, and a retaining lip 22 at the back end of the breaking bolt 2, the retaining lip 22 being supported by the front face 13 of the registration site 12 at the bottom.

(10) The conical head 4 is linked with the registration site 12 of the base 1, the conical head 4 having a conical surface 41 on the front side, the conical surface 41 including a hole 421 in the middle, the hole 421 connecting to a holding hole 42 in the conical head 4, the holding hole 42 having the second limit second 422, and the breaking bolt 42 and the elastic element 3 being inserted in the holding hole 42, the elastic element 3 being linked with the outer periphery of the breaking bolt 2.

(11) Said first binding site 11 has the first thread section 111, the body B having the second binding site B1, the second binding site B1 including the second thread section B11, the first thread section 111 and the second thread section B11 interlocking with each other.

(12) Said body B is a baton (as shown in FIG. 3), the breaking device A being installed in the tail end of the body.

(13) As shown in FIG. 4, during assembly of the breaking device A of the present invention, the first thread section 111 of the first binding site 11 of the base 1 interlocks with the second thread section B11 of the second binding site B1 of the body B to fix the base 1 onto the body B. Then, the breaking bolt 2 and the elastic element 3 are inserted into the holding hole 42, the elastic element 3 being linked with the outer periphery of the breaking bolt 2 to link the breaking bolt with the base 1. Lastly, the conical head 4 is linked with the registration site 12 of the base 1 to ensure that the first limit section 122 completely passes through the second limit section 422 and is closely connected to the second limit section 422 without falling, in which way, the conical head 4 can only move back and forth along the sliding section 121 of the registration site 12. The back end of the elastic element 3 is supported by the front surface 13 of the registration site 12 with the front top of the elastic element 3 against the front edge of the holding hole 42 of the conical 4 so that the conical head 4 supported by the elastic element 3 can maintain the forward state and the breaking bolt 2 can be hidden in the holding hole 42 without exposure, in which way, the sharp conical tip 21 will not extend to scratch any persons or articles, ensuring the use safety.

(14) FIG. 5 is the action sketch of the present invention. When using the breaking device to smash a door or car window glass G, the conical surface 41 of the conical head 4 of the breaking device A hits the surface of the glass G. During application of force, the conical head 4 touches the surface of the glass G and slides back to press the elastic element 3, and then, the sharp conical tip 21 of the breaking bolt 2 extends out of the hole 421 and smash the glass G. Because the inertial force exceeds the bearing capacity of the glass G, the great force generated instantly breaks the surface of the glass G, making it easier and safer to quickly smash a door or car window and ensuring rescue without delay.

(15) FIG. 6 is an embodiment of the breaker of the present invention, wherein, the breaking device A of the present invention is fixed onto the front side of the body C and the body C is a breaker grip.

(16) To summarize, the breaking device of the present invention is used in combination with baton and breaker for smashing door and car windows. When not in use, the breaking bolt is hidden in the conical head to avoid scratching any persons or articles and ensure user safety. Therefore, the existing shortcomings of the conventional breaking device are overcome with a new technology of the present invention, proving the novelty and progressiveness of the present invention as a utility model patent.

(17) The embodiment provided by the present invention is only used to explain the technology of the present invention, but does not attempt to, impose any form of restrictions to the present invention with said embodiment, and therefore, where there is made in the spirit of the invention and the following claims under the same in relation to any changes to the present invention, all should still include in the scope of the present invention.
