Abstract
The invention discloses a bus safety hammer with two suckers. The safety hammer comprises a hand pull rod, wherein the middle part of the hand pull rod is connected with a steel rod perpendicular to the hand pull rod; a harsh part is arranged at the front end of the steel rod; and sucker devices perpendicular to the hand pull rod are respectively connected to the two ends of the hand pull rod; the sucker devices comprise sleeves. Push rods are arranged in the sleeves. One ends of the push rods extend out of the sleeves and are connected with the hand pull rod. Stoppers are arranged on the other ends of the push rods. Springs are arranged between the ends, connected with the hand pull rod, of the push rods and the stoppers. Suckers are arranged at the other ends of the sleeves. The safety hammer can crack glass in a single process and the sucking capability of the suckers is not affected. The bus safety hammer can easily pull up a glass sheet, so that injury caused by broken glass can be avoided.
Description
Technical field
The invention belongs to mechanical device field, particularly a kind of safety hammer used for buses with Double-sucker.
Background technology
On bus, accident causes personal casualty, rapid evacuation crowd, and present bus is provided with safety hammer, to break glass into pieces at Emergency time, from car window escaping.But from daily security consideration, present vehicle glass used for buses is durable, not broken in order to prevent life-saving hamer from pounding, all on glass, be provided with fixing beating point, knocking this position can play a multiplier effect.But many times, in case of emergency cannot accurately locate.Applicants have invented a kind of safety hammer of the single sucking disc, accurately can locate beating point, but there are the following problems:
1, only have a sleeve spring, dynamics is large not;
2, knock posterior sucker place and enter air, adsorption affinity is disappeared, cannot the glass of pull-up fragmentation.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of safety hammer used for buses with Double-sucker, increasing the dynamics of knocking, and avoid can not the shortcoming of pull-up glass.
To achieve these goals, the technical solution used in the present invention is:
A kind of safety hammer used for buses with Double-sucker, comprise hand lever 3, perpendicular steel pole 5 is connected in the middle of hand lever 3, there is sharp portion 8 front end of steel pole 5, the two ends of hand lever 3 are connected to perpendicular Acetabula device, described Acetabula device comprises sleeve 6, push rod 2 is had in sleeve 6, one end of push rod 2 is stretched out and is connected hand lever 3 from sleeve 6, the other end of push rod 2 arranges stop block 1, connect to overlap between one end of hand lever 3 and stop block 1 at push rod 2 and have spring 4, the other end of sleeve 6 is provided with sucker 7.
Compared with prior art, the present invention disposablely can break glass into pieces, and sucker suction ability is unaffected, and energy is pull-up glass easily, prevents cullet from hurting sb.'s feelings.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of safety hammer used for buses with Double-sucker, comprise hand lever 3, perpendicular steel pole 5 is connected in the middle of hand lever 3, there is sharp portion 8 front end of steel pole 5, the two ends of hand lever 3 are connected to perpendicular Acetabula device, described Acetabula device comprises sleeve 6, push rod 2 is had in sleeve 6, one end of push rod 2 is stretched out and is connected hand lever 3 from sleeve 6, the other end of push rod 2 arranges stop block 1, and connecting to overlap between one end of hand lever 3 and stop block 1 at push rod 2 has spring 4, and the other end of sleeve 6 is provided with sucker 7.
During use, sucker 7 is adsorbed on the beating point both sides on glass, backward pull-up hand lever 3, then loose one's grip, under the effect of two ends spring 4, the very large power of sharp portion 5 hits beating point, then to help pull a cart cylinder 6, utilize sucker 7 to drive glass, the glass of breakage can be ripped.
