Abstract

The utility model relates to a pricking-proof outer cover with steel sheets, and belongs to a tyre. The pricking-proof outer cover with steel sheets is used as an outer cover for various rubber tyres. The pricking-proof outer cover with steel sheets is characterized in that the pricking-proof outer cover with steel sheets is provided with hose lining, a canvas layer, mesh pricking-proof thin steel sheets and cover rubber in turn from inside to outside along the cross section of the outer cover. The layers are vulcanized and mutually glued to form an integral body. The pricking-proof outer cover with steel sheets has the advantages that the structure is simple, the pricking-proof outer cover with steel sheets is easily processed, the mesh thin steel sheets are pricking-proof and glue penetrating, the layers are glued firmly, the outer cover is firm and durable, the maintenance times are reduced, the transportation time is increased, etc.

Description

Add the anti-tie cover tire of steel

A kind of anti-tie cover tire of steel that adds belongs to tyre technology, is mainly used in the various rubber mass tires of road transport.

No matter the self-propelled vehicle or the rubbery cover tyre of unpowered vehicle all are to be made of inside and outside glue-line therebetween canvas layer in prior art.This cover tire is when running into sharp object on the road surface such as point nail up etc., often passing cover tire is punctured together with the inner tube of a tyre, sometimes make reprisals driver's people of naughty child or want takes advantage of the driver and deliberately exits to wheel with awl etc. when off guard, so not only increased cost of maintenance, and delay haulage time, as occur in the field and also can cause great difficulty and trouble to the driver.

It is a kind of simple in structure that the purpose of this utility model is to provide, and easily processing is sturdy and durable, and what can prevent to puncture the inner tube of a tyre adds the anti-tie cover tire of steel.

According to the characteristic of rubber and the characteristics of tire, at the subject matter that exists in the prior art, basic design of the present utility model is: add the anti-tie sheet steel of one deck again corresponding to the tire position of contacting to earth between the canvas layer of known rubber mass cover tire and outer layer glue.

Anti-tie its transversal surface of outer tyre bead of steel that adds described in the utility model is made of hose lining [1], canvas layer [2] and outer layer glue [4] from inside to outside successively, it is characterized in that the described anti-tie cover tire of steel that adds also is provided with netted anti-tie sheet steel [3] corresponding to the cover tire position of contacting to earth between above-mentioned canvas layer [2] and outer layer glue [4], and each above-mentioned layer composes one mutually.

Above-mentioned netted anti-tie sheet steel [3] for its width and shape all with the cover tire consistent and flexible steel plate uniform seep through aperture on it in position of contacting to earth.

Only the utility model has the advantages that and between known cover tire canvas layer and outer layer glue, added one deck sheet steel, simple structure, the factory of original production tire need not increase any equipment and not change technology yet and can change the line of production, because added sheet steel is the checkered sheet of uniform aperture, this aperture can seep through makes itself and other each layer gummed firm, can stop sharp thing to pass again, prevent that them from pricking cover tire, puncture the inner tube of a tyre, reduce service expenditure, increase haulage time, save Tire ﹠ Tube, this cover tire is sturdy and durable, for the driver provides convenience.

Accompanying drawing is one of the utility model most preferred embodiment integral structure schematic cross-sectional view.1 hose lining among the figure, 2 canvas layers, 3 netted anti-tie sheet steels, 4 outer layer glues.

In conjunction with the accompanying drawings and most preferred embodiment, further describe architectural feature of the present utility model as follows: this embodiment is the cover tire of motor tire, along its transversal surface (disconnecting) along the perpendicular line on spoke plane from inside to outside successively by hose lining 1, canvas layer 2 (rubber is also arranged between each layer canvas), its width and the shape of rubber mass all and the contact to earth consistent and anti-tie sheet steel 3 of a hoop net shape of small garden holes uniform many diameter 0.1～0.2mm it in position and the outer layer glue 4 of rubber mass of cover tire constitute, above-mentioned each layer glues together mutually and becomes one through vulcanizing one-shot forming.

Change as present embodiment:

1, the utility model can be used for automobile, motor bike, carriage, arrange various rubber mass cover tires such as car, bicycle;

2, the number of plies of canvas and raw MAT'L thereof can change according to the different of tire size and vehicle type;

3, netted steel-sheet width, thickness, hole size shape etc. all can suitably change.

Claims (2)

1, a kind of anti-tie cover tire of steel that adds, constitute by hose lining [1], canvas layer [2] and outer layer glue [4] successively from inside to outside along its transversal surface, it is characterized in that the described anti-tie cover tire of steel that adds also is provided with netted anti-tie sheet steel [3] corresponding to the cover tire position of contacting to earth between above-mentioned canvas layer [2] and outer layer glue [4], and each above-mentioned layer composes one mutually.

2, the anti-tie cover tire of steel that adds according to claim 1, it is characterized in that above-mentioned netted anti-tie sheet steel [3] for its width and shape all with the cover tire consistent and flexible steel plate uniform seep through aperture on it in position of contacting to earth.
