Abstract
The utility model provides a net type framework rubber air sac. The utility model solves the problems of disengagement of overlapping surfaces, bursting, poor integration performance, etc. existing in the existing air sac. The utility model comprises an air sac body. The utility model is characterized in that the air sac body comprises an inner liner layer, a middle net layer and a rubber covering layer, wherein the net layer is a woven net layer, and is in an integral type which has no seams; the net layer is covered by the rubber covering layer; framework materials are woven net layers and are in an integral type which has no seams; the woven net layers are connected, and have no weak stress surfaces. The whole performance can be improved. The disengagement phenomenon of a combination part can not occur. The bursting can be reduced, and the service life can be extended.
Description
Technical field
The utility model relates to a kind of air bag, specifically is mainly used in the delivery boats and ships air bag of water up and down.
Background technology
At present, in shipbuilding yard and repairing yard, for hydromining rail under the large ship, and rubber pneumatic bag is adopted in medium and small launching more.During following water, boats and ships are supported by several air bags, and boats and ships are by towed equipment or towboat traction, and trailed boats and ships move on air bag, until water down.But existing rubber pneumatic bag is used the air bag of the bonding usefulness of rubber cord mostly, its bonding frame mode mainly contains two big classes, and there are following problem in bridging type and wound form, bridging type: 1. the cord of kiss-coating is reeled, bonding in the faying face intersection, be rolled into cylindricality or bevelled gas container at last.Major defect be faying surface in conjunction with insecure, be the weak link of air bag, after carrying, easily throw off explosion from here.2. faying surface waste material.There is following problem in wound form: on the mould cord is vertically being pasted, be crossed as 45 then and twine two-layer cord round about, last two ends become cone, the centre is cylindrical gas container, shortcoming is that the rubber framework material force structure is subjected to that adhesive ability limits between cord, secondly, is to bond together between cord, bonding not firm easily, overall performance is bad.
How solving the problem of above-mentioned existence, then is the design problem that the utility model faced.
Summary of the invention
The utility model provides a kind of net formula skeleton rubber air bag, and it can solve faying surface disengagement, the explosion that existing air bag exists, problems such as overall performance difference.
In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is, a kind of net formula skeleton rubber air bag, it comprises pneumatophore, it is characterized in that described pneumatophore comprises bladder layer, middle stratum reticulare, and rubber covering layer, described stratum reticulare is mesh grid, be the integral type that does not have seam, stratum reticulare covers with rubber covering layer.
In the utility model, also have following technical characterictic: the grid intersection point of described stratum reticulare is woven with the tubercle latch closure.
In the utility model, also have following technical characterictic: described stratum reticulare is one or more layers, and the coat with rubber overplate is that one deck one is coated with, or multilayer one is coated with.
In the utility model, also have following technical characterictic: the stratum reticulare that suit has woven on inner bag, or on inner bag direct woven mesh layer.
In the utility model, also have following technical characterictic: the grid of described stratum reticulare is square.
The utility model compared with prior art has the following advantages and good effect: 1. framework material is a woven mesh layer, and for there not being the integral type of seam, from being connected, there is not weak stress surface, overall performance is improved, the joint portion can not occur and throw off phenomenon, greatly reduce explosion, long service life.2. the grid joint place of stratum reticulare is woven with the tubercle latch closure, can make each grid producing balanced forces, and can not make the grid sliding deformation, has improved tension and compressive strength.3. employing stratum reticulare, rubber covering layer can see through grid, thereby inner bag, stratum reticulare and rubber covering layer form one, and gleyness and globality improve greatly.4. substantially without lining cement, save the parallel material, alleviated product weight.

Fig. 2 is an I position enlarged drawing among Fig. 1;
Fig. 2 is the utility model net formula skeleton rubber air bag part sectional view.
1, net formula skeleton rubber air bag; 2, air inlet/outlet; 3, rubber covering layer; 4, stratum reticulare; 4-1, grid; 4-2, tubercle latch closure; 5, rubber liner.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the air bag of Fig. 1, Fig. 3 is the formed form in inflation back.Net formula skeleton rubber air bag of the present utility model is used mark 1 chief representative.Nexine is a rubber liner 5, inner bag 5 wall thickness range are 2～6mm, the cover last layer has woven the stratum reticulare 4 that finishes on inner bag 5, and stratum reticulare adopts p-aramid fiber, nylon rope, textile rope braiding to form, and the rope diameter is about 0.5～1.2mm, the grid 4-1 of braiding is a square, square side size range 5-10mm, the joint of each grid 4-1 is made into tubercle latch closure 4-2, i.e. fishing net formula button, the stratum reticulare 4 of whole braiding is an integral type, does not have seam.It is the shape of cone intermediate cylindrical that stratum reticulare 4 forms two ends.Stratum reticulare is coated rubber covering layer 3 after being sleeved on the inner bag 5.
Generally speaking, being one deck stratum reticulare 4 one coat with rubber overplates 3, also can be a two-layer at least above coat with rubber overplate 3.
Manufacturing step generally is divided into three steps:
1. made inner bag 5 as required, inflation rear enclosed air inlet/outlet 2, be pressure bladder be again outer field mould;
2. directly weave the woven mesh layer with latch closure 4 that fits like a glove with inner bag, or put the tubercle latch closure stratum reticulare 4 that has woven;
3. coat the rubber cement of rubber covering layer 3, or given the rubber covering layer 3 that makes on pasting, its effect is to fill and fixing stressed net, thereby is bonded to one.
Certainly, the utility model is not limited to above-mentioned giving an example, and in essence intention scope of the present utility model, the utility model also has many variations, remodeling or replacement, all should belong to protection domain of the present utility model.
