Description

Flame-retardant EVA foam convenient to store
Technical Field
The application relates to the field of foam, concretely relates to convenient fire-retardant EVA bubble of accomodating is cotton.
Background
The EVA foam is a foaming material, has the characteristics of good noise reduction, heat preservation, high elasticity and the like, has more applications in the industrial and living fields, for example, in the living field, the EVA foam is often used for manufacturing various fitness mats, and can be conveniently used as the fitness mats to protect the bodies of fitness personnel due to good elasticity and the optional required thickness. However, the use of the health mat has disadvantages that, firstly, the general health mat does not have flame retardant property, and if it comes into contact with an object such as a cigarette butt during use, it is likely to be dangerous, and it does not have flame retardant property. In addition, the body-building cushion needs to be stored after the body-building is finished, but the general storage mode is to roll up the body-building cushion, but the body-building cushion which is just finished with the body-building has much sweat, and if the body-building cushion is directly rolled up, the body-building cushion is easy to go moldy and breed bacteria. If the mattress is dried and rolled, the body-building cushion in the unfolded state occupies a large space.
Disclosure of Invention
The purpose of the invention is as follows: the application aims at overcoming the defects of the prior art and provides the flame-retardant EVA foam convenient to store.
The technical scheme is as follows: the flame-retardant EVA foam convenient to store comprises two flame-retardant protection units and two EVA foam bodies, wherein the two EVA foam bodies are equal in length, the end parts of the two EVA foam bodies are connected through a connecting strip, strip-shaped convex ribs are arranged on two sides of the EVA foam body, and the strip-shaped convex ribs and the EVA foam bodies are integrally formed; the fire-retardant protection unit includes fire-retardant overburden and be located fire-retardant overburden both sides with fire-retardant overburden fixed connection's bar supporting part, the inboard of bar supporting part has two spacing, form between two spacing with protruding muscle complex bar slot of bar.
Further, the cross sections of the bar-shaped convex ribs and the bar-shaped slots are both rectangular, or the cross sections of the bar-shaped convex ribs and the bar-shaped slots are both trapezoidal.
Because the cotton bar protruding muscle of EVA bubble has elasticity, consequently can not fall out from the slot to trapezoidal slot and trapezoidal protruding muscle can further place protruding muscle landing from the slot.
Furthermore, the two flame-retardant protection units are respectively a first flame-retardant protection unit and a second flame-retardant protection unit, the length of the first flame-retardant protection unit is greater than that of the EVA foam body, and the length of the second flame-retardant protection unit is less than that of the EVA foam body; two strip-shaped convex ribs of one EVA foam body are respectively inserted into two strip-shaped slots of the first flame-retardant protection unit; two strip-shaped convex ribs of the other EVA foam body are respectively inserted into two strip-shaped slots of the second flame-retardant protection unit.
Further, the absolute value of the difference between the lengths of the first flame-retardant protection unit and the EVA foam body is equal to the absolute value of the difference between the lengths of the second flame-retardant protection unit and the EVA foam body.
Therefore, when the EVA foam is in an unfolded state, the sum of the lengths of the two EVA foam bodies is equal to the sum of the lengths of the two flame-retardant protection units.
Furthermore, a first cylindrical fixing column and a second cylindrical fixing column are arranged on the inner side of the end part, far away from the connecting strip, of the strip-shaped supporting part, a first limiting cap is arranged at the end part of the first fixing column, a second limiting cap is arranged at the end part of the second fixing column, the second fixing column penetrates through the rotating supporting leg, the rotating supporting leg can rotate along the second fixing column, the rotating supporting leg is connected with a drag hook through an elastic rope, and the two rotating supporting legs of the first flame-retardant protection unit and the two rotating supporting legs of the second flame-retardant protection unit correspond to each other one by one; the flame-retardant EVA foam can be in an unfolded state and a stored state, in the unfolded state, the upper surface of the flame-retardant covering layer of the first flame-retardant protection unit is flush with the upper surface of the flame-retardant covering layer of the second flame-retardant protection unit, and the drag hook of each rotating supporting leg hooks the first fixing column at the strip-shaped supporting part where the rotating supporting leg is located; in the state of accomodating, the lower surface butt second EVA of the cotton body of first EVA bubble steeps the lower surface of the cotton body of second EVA bubble, and every rotates the outside that the supporting leg all stretched out its place bar-shaped supporting portion to the drag hook of two corresponding rotation supporting legs catches on each other.
Further, the second limit cap is supported by elastic materials and abuts against the rotating supporting leg, so that the rotating supporting leg can rotate along the second fixing column only by means of external force.
Further, the both ends of the protruding muscle of bar and the both ends of the cotton body of EVA bubble all have one section distance, the tip that the connecting strip was kept away from to the bar slot has one section distance between the tip that the connecting strip was kept away from to the bar supporting part at its place, first fixed column, second fixed column and the rotation supporting leg is located the bar supporting part and keeps away from between the tip that the connecting strip was kept away from to the tip and the bar slot of connecting strip.
Because the distance has between the tip of keeping away from the connecting strip tip of bar slot and the connecting strip is kept away from to bar supporting part to have a distance between the tip of the cotton body of bar protruding muscle and EVA bubble, thereby reserve the space for the installation of rotating the supporting leg. The rotating support leg is sheet-shaped.
Further, a plurality of anti-skid protrusions are arranged at the strip-shaped supporting part, the strip-shaped supporting part is made of rubber materials or plastics, and the anti-skid protrusions and the strip-shaped supporting part are integrally formed; the limiting strip and the strip-shaped supporting part are integrally formed.
Further, two EVA bubble cotton bodies are first EVA bubble cotton body and second EVA bubble cotton body respectively, first EVA bubble cotton body, second EVA bubble cotton body and connecting strip integrated into one piece.
Further, the flame-retardant covering layer is made of flame-retardant fibers.
Further, optionally, the fire retardant cover layer is made of fire retardant cotton. Or the flame-retardant covering layer is made of flame-retardant cloth. Or may be made of other flame retardant materials.
Has the advantages that: the EVA foam of the application is cotton owing to have fire-retardant protective layer, consequently when using, because the cotton body of EVA foam is covered to fire-retardant protection unit, even if consequently article such as cigarette ends drop carelessly and also can not arouse the burning, can clear up the cigarette end smoothly. And the convenience is to the cotton accomodating of EVA bubble, can expand the use, also can accomodate very conveniently, accomodate the fire-retardant protection unit that is stained with sweat after finishing outwards to whole by 4 rotation supporting legs supports, thereby take up an area of for a short time, and sweat can evaporate, can not breed the bacterium.
