Abstract

The utility model provides a plastic tarpaulin which comprises a tarpaulin and a threading buckle fixed on the tarpaulin, wherein the threading buckle comprises an upper buckle and a lower buckle. The utility model is characterized in that both the upper buckle and the lower buckle are annular. The right sides of the upper buckle and the lower buckle are planes, and the upper buckle and the lower buckle are welded with the plastic tarpaulin through supersonic wave. Both the upper buckle and the lower buckle of the tarpaulin are in the shape of a plane type circular arc. The upper buckle and the lower buckle are welded with the plastic tarpaulin by the heat produced by ultrasonic vibration in an adhesive mode. The whole surfaces of the upper buckle and the lower buckle are firmly combined with the tarpaulin, and the combination is tight. Even if the buckles are pulled forcibly by roped, the upper buckle and the lower buckle can be still firmly combined, and the looseness and the disengagement can not occur. Accordingly, the purpose of the firm combination is realized.

Description

Plastic awning cloth

Technical field

The utility model relates to a kind of Plastic awning cloth, mainly is to being fixed on the improvement of Buckle structure that is used for wire rope handling of Plastic awning cloth periphery.

Background technology

The purposes of Plastic awning cloth is very extensive, covers article as lorry and warehouse with Plastic awning cloth, with avoid drenching with rain, Exposure to Sunlight.Need during the plastic covering tarpaulin to fix with rope, rein in bad Plastic awning cloth in order to prevent rope, be fixed with Buckle at the Plastic awning cloth periphery, rope passes from Buckle, and button contacts with rope, thereby the tarpaulin site of perforation is protected.Existing wire rope handling is buckled with two kinds of versions, and a kind of is the aluminium button; Another kind is the duroplasts button.

The aluminium button is not installed preceding version, and it is made of following cylinder and last disk, and following cylinder is made of chassis and the cylinder that makes progress, and cylinder heights is greatly about 6～8mm; Have a circle indent annulus in the middle of the last disk, periphery have to a circle flange.Plastic awning cloth is installed the aluminium button and is finished by dotter, after beating button and finishing, following cylinder and last disk are by the riveted compacting, the cylindrical portions may of following cylinder is pressed into a dome ring-type, be fastened in the middle indent annulus of disk, cylinder and last cylindrical shape are integral, thereby are combined on the Plastic awning cloth.Fixedly the rope of tarpaulin passes from buckleing in the interstitial hole, so that the fixed plastics tarpaulin.

Duroplasts buckle structure and aluminium button are roughly the same, just are provided with a circle pointed tooth on the chassis of descending cylinder and last disk bottom surface.After beating button, pointed tooth is embedded in the Plastic awning cloth, in the hope of reaching in conjunction with firm purpose.

Above-mentioned two kinds of buttons are found still to exist not attain to improve part through using, has following deficiency: 1, the mechanical riveted formula combination that just forms between the following cylinder of button and the last disk, the button with the tarpaulin contact surface between formation be connected closely, there is the slit between button and the tarpaulin, when the rope make-up is afterburning, easily make button loosening, be buckled in and follow the rope rotation on the tarpaulin, when serious, cause the button distortion to come off, and then tarpaulin is torn along the bearing that buckles, tarpaulin one place tears, the tear place will soon be expanded, and causes whole tarpaulin discarded.2, tarpaulin is plastic material mostly, and is different with aluminium button material.External environmental demands after tarpaulin surpasses useful life, must be pulled down the aluminium button, and the aluminium button can not together be regenerated with tarpaulin, has increased homework burden.3, no matter be aluminium button or duroplasts button, because material is hard, after use a period of time, easy deformation forms corner angle, and the workman scratches hand easily at the static line period of the day from 11 p.m. to 1 a.m.4, cost height, 10,000 about 29 dollars.5, manufacturing process complexity.6, owing to cylinder is different with last disc structure down, in beating the button operation, cylinder and last disk move respectively under carrying, and have brought trouble to beating the button operation, and efficient is low.7, complex-shaped owing to what detain, and cylinder has certain altitude down, thereby occupy transport space.How overcoming above-mentioned defective, then is the design problem that is faced.

Summary of the invention

The utility model provides a kind of tarpaulin Buckle, and that it can solve that prior art exists is fixing not firm, be unfavorable for environmental protection, cost height, and problems such as manufacturing and mounting process complexity.

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 Plastic awning cloth, it comprises tarpaulin and is fixed on Buckle on the tarpaulin, Buckle comprises upper and lower button, it is characterized in that: described upper and lower button shape is identical, upper and lower button be shaped as annular, the front of upper and lower button is the plane, and upper and lower button is welded together by super sonic and Plastic awning cloth.

In the utility model, also have following technical characterictic: the back side of described upper and lower button is the plane.

In the utility model, also has following technical characterictic: be provided with a circle fixed teeth on the front of upper and lower button at least.

In the utility model, also have following technical characterictic: described fixed teeth is column, rib shape, or protruding granular.

In the utility model, also have following technical characterictic: the front of upper and lower button is provided with three circle fixed teeth, and the fixed teeth arrangement pitches of inner ring and outer ring is close; Mesosphere fixed teeth arrangement pitches is dredged.

The utility model compared with prior art has the following advantages and good effect: 1, tarpaulin upper and lower buckled be designed to identical shaped, and be the plane formula annular arrangement, the heat that takes place by ultrasonic vibration makes button and Plastic awning cloth weld together up and down, it is the adhibit quality welding, up and down whole of button all with the tarpaulin mortise, in conjunction with tight, both made the increasing of exerting oneself of rope make-up, button loosening and break-off can not occur in conjunction with very firm yet up and down.2, button adopts flexible plastic to make up and down, can a regeneration with Plastic awning cloth, can not cause environmental pollution.3, same have the better elastic recovery performance because adopt flexible plastic to make, and can not be out of shape the formation corner angle, can not hinder the hand phenomenon.4, per ten thousand about 12 dollars, cost greatly reduces.5, shape and structure is simple, is easy to make, and installation procedure is also followed simplification, and has improved production efficiency.6, structure is the plane formula annular arrangement, and volume is little, is easy to vanning (bag) and has reduced transport space.
