Abstract

The utility model discloses the design proposal of the fastener of film. The fastener of film is composed of two fastening tapes, wherein, a convex protrusion rib is arranged on one fastening tape, a groove is arranged on the other fastening tape, and the protrusion rib and the groove are matched in a corresponding tabling type. The fastener of film with simple structure, easy production, low cost and convenience and practicability can be made of material with definite elasticity and tensile strength, such as plastic, nylon, rubber, etc. The fastener of film is especially suitable for the connection of the massive film with a large area, and when the fastener of film is disassembled, the film can not be damaged, which is favorable for the reuse of the film. The fastener of film can be heavily applied to places such as croplands, worksites, nurseries, etc.

Description

Fastener of film

The utility model belongs to film and connects goods, a kind of film Connection Card.

Usually need two films are coupled together in daily life and the production, require seam airtight, water-tight.The method that generally adopts is that thermoplastic is legal, the glue mull technique at present.The electric heating press fit device that the legal needs of thermoplastic are special, and when the seam that need to connect has that tens of rice rice up to a hundred are long, when film size must carry out on land for growing field crops or building site to hundreds of thousands of even up to ten thousand square metres and seam work greatly, the legal or glue mull technique of thermoplastic all is difficult to carry out.In addition, the seam that thermoplastic is legal, the glue mull technique is handled can not be taken seam apart under the situation of not destroying plastic sheeting, and receiving gathers into folds preserves in order to reusing later on, causes the discarded waste of a large amount of films.

The purpose of this utility model is that a kind of film of design connects goods, is applicable to that the film of various occasions connects, and makes that it is practical convenient, simple in structure, production is easy, cheap.

The purpose of this utility model realizes with the design of following film Connection Card.It is made up of cassette tape on two, it is characterized in that having convex to give prominence to muscle on the cassette tape, and is fluted on another cassette tape, and outstanding muscle becomes corresponding inserted type cooperation with groove.Outstanding muscle and groove number can be made and select for use according to actual needs.

Fig. 1 is a film Connection Card structure schematic cross-sectional view.1 is protruding band, and 2 is recessed band.Fig. 2 is the film Connection Card schematic cross-sectional view with two, three outstanding muscle, groove.Fig. 3 is the utility model Application Example schematic diagram.

This film Connection Card adopts the material that certain elasticity and tensile strength are arranged, and makes as plastics, nylon, rubber etc.Using method is as follows: 1. will need two sides of the film that connects to be piled up, place between protruding band and the recessed band, make protruding with on prominent muscle aim at recessed with on groove, the side of film longitudinally aligns (shown in Fig. 3 a) with the film Connection Card.2 make protruding band and recessed band press mutual chimeric promptly the finishing of film to be connected.(shown in Fig. 3 b).When chimeric workload little, required inlay resultant force hour, available thumb of chimeric work and forefinger are pinched and are compeled protruding band and recessed band is finished chimeric.When chimeric workload and required inlay resultant force are big, can adopt some specific purpose tools, carry out pressing as roller.

The advantage of this fastener of film is that structure is extremely simple, produces easily, and is cheap and very convenient and practical. Be specially adapted to the general connection that connects very difficult bulk large area film, and can not damage film during dismounting, be conducive to film and reuse and avoid waste.

Claims

1, a kind of film Connection Card is made up of two cassette tapes, it is characterized in that having convex to give prominence to muscle on the cassette tape, and is fluted on another cassette tape, and outstanding muscle becomes corresponding inserted type to cooperate with groove.
