Abstract
The utility model discloses a fixed type safety hammer which comprises a hammer head. The hammer head is connected at the top of an elastic connecting rod, and the bottom of the elastic connecting rod is sleeved in a fixed base through a rotation shaft and can rotate in the fixed base. The utility model has the advantages that the fixed type safety hammer has simple and compact structure, low cost, wide range of application, good adjustability and high safety and is quick, simple and easy to operate, etc.
Description
Technical field
The utility model is mainly concerned with the survival equipment field, refers in particular to a kind of safety hammer that is applicable to that containing fields such as glass port share.
Background technology
Known " safety hammer " is mainly used in sealing such as public transport bus, long-distance big bus, train occasion, is meant when unforeseen circumstances occurring, is used for adopting shattered glass, cuts off the instrument that mode such as safety strap is escaped.Traditional safety hammer structure mainly is made up of two parts: metal tup and plastics hammer handle.The deficiency of this existing structure just is: 1. safety hammer is when unused state, generally be placed in window stupefied on, be easy to just can be removed, this provides convenience just for the not high people of indivedual quality, cause safety hammer very easily to lose, the normal use when finally having influence on escape.According to investigations, the safety hammer overwhelming majority that occasions such as present public transport bus are equipped with all disappears suddenly, and has caused great potential safety hazard.2. the use energy of existing safety hammer is mainly from people's arm, and is limited to the destructive force of closures such as window.Even if safety hammer is not lost, also be difficult in use closures such as window are smashed.3. last, existing safety hammer can not be found by the user in the bad enclosed environment of light such as night easily fast, thereby has influence on the success ratio of escape.
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provides a kind of fixation type safety simple and compact for structure, with low cost, that operation is fast simple, applied widely, adjustability is good, safe to hammer into shape.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of fixation type safety hammer comprises tup, and it is characterized in that: described tup is connected in the top of an elastic link, and the bottom of described elastic link is sheathed in the firm banking by rotating shaft and can rotates in firm banking.
As further improvement of the utility model:
Described rotating shaft is positioned on the lateral wall of firm banking one end and offers more than one hole, is equiped with spring and ball in the described hole successively, offers on the madial wall of described firm banking to be used for the groove that cooperates with ball.
An end section that cooperates with firm banking in the described rotating shaft is for circular, and the end section that described firm banking cooperates with rotating shaft is for circular, and described groove is along the equidistant rectangular distribution of the circumferencial direction of firm banking.
Described tup is connected in the top of elastic link by pin.
Be coated with fluorescence coating on the described tup.
Compared with prior art, advantage of the present utility model is:
1, fixation type safety of the present utility model hammer, simple and compact for structure, with low cost, operation is fast simple, applied widely, adjustability is good, safety, adopts fixed mounting means, can prevent that it is moved or steals;
2, fixation type safety of the present utility model hammer, by the design of elastic link formula, force mechanism adopts elasticity to hold power, operates very easyly, and damage capability is strong, has improved the safety of safety hammer greatly;
3, fixation type safety hammer of the present utility model, tup can be implemented to adjust application of force angle by rotation, guarantees the accuracy of its use;
4, fixation type safety hammer of the present utility model, tup is provided with fluorescence coating, can make things convenient for the user to find fast and accurately in the dark, thereby has improved the success ratio of escape greatly.

The specific embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, fixation type safety hammer of the present utility model, comprise tup 4, tup 4 is connected in the top of an elastic link 3, and the bottom of elastic link 3 is sheathed in the firm banking 1 by rotating shaft 2 and can rotates in firm banking 1.In the present embodiment, it is motionless that firm banking 1 is fixed in attachment point by attaching parts, under unused state, vertically hang, such as by screw retention on the window rib between two glass ports, prevent to be moved or take away by the people.Firm banking 1 can adopt common grey pi iron (HT150) manufacturing to form.The material of tup 4 can adopt the 45# steel, is prepared from by modifier treatment and surface hardening.
In the present embodiment, tup 4 can adopt the secondary pulse design according to actual needs, and the tup top is a ball, and the toe back has one with the excessive step surface in inclined-plane, like this glass is had bigger destructive force.Be coated with fluorescence coating on the tup 4, be convenient to the user and find tup 4 positions, the line operate of going forward side by side in the dark fast and accurately.
In the present embodiment, elastic link 3 can adopt has very that the lightweight organic composite material PA 6 of high resiliency intensity is made, and its cross section is circular, can increase the intensity of elastic link 3 like this, it has two distinguishing features: the one, and elasticity is big, and the 2nd, cost is low, popularizes easily and applies.One end of elastic link 3 links to each other with rotating shaft 2 by the pin joint mode, and the other end is captiveed joint with tup 4 by pin 5.Simultaneously, between rotating shaft 2 and firm banking 1, adopt elastomeric material preferably, can cushion the application force of 3 pairs of firm bankings 1 of elastic link.
Theory during actual the use is calculated:
Material known parameters: case hardened glass parameter: sample: the 920mm * 840mm * about 100Mpa of 5mm center compressive strength σ bc.
Elastic link 3: material: high resiliency PA nylon rod; Size Φ 20mm * 600mm modulus of elasticity: E=28.3GPa; Poisson's ratio: μ=0.4;
The quality of tup 4: M=200g.
Adopt the analysis of LS-DYNA simulated stress: when institute's loading power was 12kg, the data display toe maximum of gained can produce the compression effort 100Mpa of the compression effort of 103.8Mpa greater than the maximum that case hardened glass allowed.
When reality is used, at first find the position of tup 4, after rotating to an angle by rotating shaft 2 then, adjust the direction of tup 4, make its toe place aim at closure; Then hold the ball at tup 4 tops, aligning is wanted broken closure (for example window) and is pulled back, and full power is also held in elastic link 3 bendings; When load force is 12kg, but just shattered glass of the energy of tup 4 savings.
Below only be preferred implementation of the present utility model, protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art the some improvements and modifications not breaking away under the utility model principle prerequisite should be considered as protection domain of the present utility model.
