Abstract
The utility model relates to an emergency escape breathing device with a coupling chain component. The device comprises a backpack, an air flask arranged in the backpack, a head valve arranged on the air flask, a head cap component connected with the head valve and a coupling chain connecting the head valve and a zipper head of the backpack, wherein the coupling chain comprises a chain body and a bolt which is connected to one end of the chain body and is arranged in a limiting groove of a hand wheel of the head valve to limit the opening and closing of the head valve; the other end of the chain body is connected with the zipper head of a sealed zipper on the backpack; and when the bolt is arranged in the limiting groove, the length of the coupling chain is suitable for limiting the travel of the zipper of the backpack, so the head cap component cannot be taken out of the opening of the backpack. By the emergency escape breathing device, an aim that the head cap component cannot be taken out and used if an air source is not opened first is fulfilled, so that the emergency escape breathing device can be rightly operated by rattled people in an emergency escape, and a phenomenon that users choke in the head cap because the users forget to open the head valve is avoided.
Description
Technical field
The utility model relates to a kind of Emergency Escape Breathing Device with connection chain assembly.
Background technology
Emergency Escape Breathing Device is the survival equipment that uses when breaking out of fire, the user tends to because the reason such as nervous, flurried during use, tend to forget the opening bottles head valve after the head-shield of Emergency Escape Breathing Device is put on, this very easily causes the user to suffocate in head-shield.
How making people's opening bottles head valve at first before putting on head-shield, avoid forgetting the opening bottles head valve, is this area technical problem to be solved.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, can make the people before putting on head-shield first opening bottles head valve to guarantee to use the safe Emergency Escape Breathing Device with connection chain assembly.
In order to address the above problem, the utility model provides a kind of Emergency Escape Breathing Device with connection chain assembly, and it comprises: the knapsack of band sealing slide fastener, be located at air bottle in this knapsack, be located at the bottle valve on this air bottle, the hood assembly that links to each other with this bottle valve, be connected in described bottle valve and knapsack slider of zipper fastener between connection chain; Described connection chain comprises: serobila, the stopper slot of handwheel that is used for being arranged on described bottle valve that is connected in this serobila one end are opened the latch of described bottle valve with restriction; The slider of zipper fastener of the sealing slide fastener on the other end of this serobila and the described knapsack links to each other; When described latch was located at described stopper slot, the length of described connection chain was suitable for limiting the stroke of the slide fastener of knapsack, and made the openings of sizes of knapsack be suitable for restriction described hood assembly is taken out; Or the other end of described serobila links to each other with described hood assembly, and the length of described connection chain is 15-25cm, and with when described latch is located at described stopper slot, the length of connection chain can limit described hood assembly is applied on user's head.
Further, be arranged with heat-shrinkable T bush on the described serobila, guarantee the reliability of serobila.
The utility model has positive effect with respect to prior art: the latch that the Emergency Escape Breathing Device with connection chain assembly of the present utility model has utilized restriction to open described bottle valve is connected with an end of a connection chain, the other end of connection chain connects the slide fastener on the knapsack, the length of connection chain is suitable for limiting the unlatching of slide fastener, so that having reached, this device do not open first source of the gas, the purpose that can't take out hood assembly and use, so that flurried people can the proper operation Emergency Escape Breathing Device during emergency escape, avoid the opening bottles head valve occurring forgetting and cause user's asphyxiant situation in head-shield.
Description of drawings
Fig. 1 is the structure chart of connection chain assembly of the present utility model;
Fig. 2 is the structure chart of Emergency Escape Breathing Device of the present utility model when not using;
Fig. 3 is the state diagram that is suitable for of above-mentioned Emergency Escape Breathing Device.
The specific embodiment
See Fig. 1 to 3, the Emergency Escape Breathing Device with connection chain assembly of present embodiment comprises: the knapsack 6 of band sealing slide fastener, be located at air bottle 7 in this knapsack 6, be located at the bottle valve 1 on this air bottle 7, the hood assembly 3 that links to each other with this bottle valve 1, be connected in described bottle valve 1 and knapsack 6 slider of zipper fastener between the described sealing slide fastener of connection chain 2(comprise slider of zipper fastener).Described connection chain 2 comprises: serobila 2-3, be connected in this serobila 2-3 one end be used for be arranged on described bottle valve 1 handwheel stopper slot latch 2-1, be connected in the key chain 2-5 of slider of zipper fastener that is used for connecting described knapsack 6 of the other end of this serobila 2-3.
When latch 2-1 is located in the described stopper slot, be suitable for limiting the hand wheel rotating of described bottle valve 1, open described bottle valve 1 with restriction.When described latch 2-1 was located at described stopper slot, the length of described connection chain 2 was suitable for limiting the stroke of the slide fastener of knapsack 6, makes the size of knapsack 6 openings be suitable for restriction hood assembly 3 is taken out.Be arranged with heat-shrinkable T bush 2-4 on the serobila 2-3.
During use, handwheel on the bottle valve 1 rotates counterclockwise, open bottle valve 1, and the latch 2-1 that will insert in described stopper slot breaks away from described stopper slot, make described connection chain 2 no longer limit the stroke of described slider of zipper fastener, the user can open knapsack 6 and take out hood assembly 3, then is worn on the head normal use.
As another embodiment, the other end of described serobila links to each other with described hood assembly, and the length of described connection chain is 15-25cm, and with when described latch is located at described stopper slot, the length of connection chain can limit described hood assembly is applied on user's head.
Obviously, above-described embodiment only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And these belong to apparent variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
