Abstract
The utility model discloses a lifebuoy with double-layer air chambers. A steel mold in a structure as follows is manufactured. The diameter of the lifebuoy, namely the diameter of the largest circle of a protective surface layer air chamber, is about 80cm. The diameter of a cross section circle of the lifebuoy, namely the largest circle of the cross section of the protective surface layer air chamber, is about 16cm. The diameter of the smallest circle of the protective surface layer air chamber is 48cm. The circumference of the smallest circle of the protective surface layer is about 150cm. The thickness of the protective surface layer air chamber is about 1cm. The protective surface layer is divided into 144 single sealed air chambers longitudinally and transversely according to the arc length of 30 degrees. A circle core layer is wrapped through the protective surface layer, a circle core layer air chamber is located in the center of the lifebuoy, and the circle core layer is divided into 12 sealed air chambers transversely according to the arc length of 30 degrees. The steel mold in the shape and the structure is utilized, the lifebuoy is poured and manufactured with materials of plastics or rubber, and inflation technique enables each single air chamber to have sufficient air.
Description
One, technical field
The utility model relates to a kind of water survival instrument, especially relates to a kind of two-layer air chamber buoy quoit.
Two, background technology
Buoy quoit a bit produces micropore gas leakage, just loses the lifesaving ability, as for the end user drowned danger occurs, and is a large defective really.
Three, utility model content
In order to overcome the deficiency of above technology, the purpose of this utility model provides a kind of two-layer air chamber buoy quoit, form by protecting the top layer air chamber and enclosing the sandwich layer air chamber, it is characterized in that, protect the top layer air chamber and be wrapped in circle sandwich layer air chamber, be positioned at the appearance aspect of buoy quoit, protect the top layer and be provided with each self-enclosed dozens of, even up to a hundred air chambers that volume does not wait, it is shaped as slightly curved hexahedron, circle sandwich layer air chamber is the inflated cylindrical enclosure that is positioned at buoy quoit central authorities, cylindrical enclosure is provided with more than ten each self-enclosed air chamber, and the shape of each air chamber is one section slightly curved cylinder, also can be one section slightly curved polyhedron.
The technical scheme that the utility model adopts is, make the following punching block of its shape and structure, the diameter 80cm of buoy quoit, namely protect the diameter 80cm of the circle of top layer air chamber maximum, the girth that protects the great circle in top layer is 80 * 3.14=251cm, the diameter 16cm of the cross-section tangent plane circle of buoy quoit, namely protect the diameter 16cm of the great circle in air chamber square section, top layer, protect the diameter 80-32=48cm of the minimum circle of top layer air chamber, protect the Zhou Changyue 48 * 3.14=150cm of the ringlet in top layer, the thickness that protects the top layer air chamber is 1cm approximately, undertaken vertically by 30 degree arc length protecting the top layer, laterally be divided into the air chamber of single sealing, then this protects the top layer and is configured to 144 air chambers, and it is shaped as slightly curved hexahedron, the volume of 20 * 4 * 1＞single air chamber＞13 * 4 * 1 (cm3).Protect the top layer and be wrapped in the circle sandwich layer, circle sandwich layer air chamber is positioned at buoy quoit central authorities, laterally be divided into 12 closed air chambers by 30 degree arc length, the shape of each air chamber be arc length approximately the radius of 16cm be the cylinder of 7cm, if circle sandwich layer air chamber is set to a circle polyhedron, then single circle core air chamber then is the slightly curved polyhedron that is about 16cm.Use the punching block of above shape and structure, the utility model is produced in cast take plastics or rubber as material, and uses the inflation technology to make each single air chamber that sufficient gas be arranged.
The beneficial effects of the utility model are: protect the single air chamber that there are 144 sealings on the top layer; effectively protect whole buoy quoit to be in fully inflated situation; even buoy quoit is subject to frustrating hitting to bump and beats and make the somewhere holes occur; also only have and somely protect the top layer air chamber and leak gas; do not hinder the life-saving functions of whole circle, greatly improved safety factor and the service life of buoy quoit.
Four, description of drawings
Fig. 1 is the structural representation of the utility model vertical section; Fig. 2 is the structural representation that protects the vertical section in top layer; Fig. 3 is the circle sandwich layer structural representation of totally 12 air chambers; Fig. 4 is that the circle sandwich layer is the cross section structural representation of a circle; Fig. 5 is that the circle sandwich layer is the polyhedral cross section structural representation of a circle.
Among the figure, 1, protect the top layer; 2, protect the single air chamber in top layer; 3, circle sandwich layer; 4, the single air chamber of circle sandwich layer; 5, protect the maximum circle in top layer; 6, protect the minimum circle in top layer.
Five, the specific embodiment
As shown in the figure, the utility model is to protect top layer (1) parcel circle sandwich layer (3) to form buoy quoit, protect (2) 144 of the single air chambers in top layer, (4) 12 of the single air chambers of circle sandwich layer, the equal top off of each air chamber, even buoy quoit is subject to frustrating of external force and hits to bump and beat and make somewhere gas leakage, also just miss the gas of per centum of whole buoy quoit, do not hinder integral body, strengthened the effect of the resisting breakage of buoy quoit, improve the safety factor of lifesaving, prolonged the service life of buoy quoit.
Claims (1)
1. two-layer air chamber buoy quoit, form by protecting the top layer air chamber and enclosing the sandwich layer air chamber, it is characterized in that, protect the top layer air chamber and be wrapped in circle sandwich layer air chamber, be positioned at the appearance aspect of buoy quoit, protect the top layer and be provided with each self-enclosed dozens of even up to a hundred the air chambers that volume does not wait, it is shaped as slightly curved hexahedron, circle sandwich layer air chamber is the inflated cylindrical enclosure that is positioned at buoy quoit central authorities, cylindrical enclosure is provided with more than ten each self-enclosed air chamber, the shape of each air chamber is one section slightly curved cylinder, also can be one section slightly curved polyhedron.
