Abstract

The utility model discloses an automatic charge ratio disinfecting washing device, which adopts the mutual matching of a strip casing of which the cross section shows convex and a strip inner core of which the cross section shows concave. A plastic film can be clamped and fixed between both. The utility model has the advantages of good form property, good seal, good thermal insulation, time saving, and labor saving; the utility model can be continuously used, and the dismantlement and mounting does not damage the plastic film; the plastic film is easy to fix and level.

Description

Fixture for plastic film

The utility model is a kind of being specially adapted to plastic sheeting or the similar utensil fixed of soft-body.

A large amount of plastic sheetings that adopt constitute frame formula greenhouse on agricultural, and room, house in winter seals window with plastic sheeting, reaches the purpose of sealing insulation, all can receive effect preferably.But adopting metal nail and so on to hammer in the corresponding skeleton usually to plastic sheeting at present fixes.This fixing means-the deficiencies in the prior art part is: 1. use inconvenience, each construction effort is time-consuming, can only fix bit by bit or dismantle, and moulding is difficult for smooth attractive in appearance; 2. plastic sheeting and wooden skeleton etc. is all caused certain damage, especially door window frame is dismantled repeatedly, is installed, and nails on, takes off, and the full of stains or spots influence of vestige is attractive in appearance, shortens the application life of door window frame; 3. plastic sheeting, securing member and auxiliary materials etc. is not easy to reuse, and every dismounting once causes certain loss and waste easily, and expense increases.

But being to avoid above-mentioned the deficiencies in the prior art part, the purpose of this utility model provides a kind of with the fixing repeated disassembled and assembled plastic sheeting fixator product easy to use of face contact.

Can be by following measure, reach the purpose of this utility model, adopt cross section to be the strip shell of spill and strip inner core that cross section is convex cooperatively interacts, plastic sheeting is between shell and the inner core, and the bayonet socket place of inner core band film by shell is installed on both concavo-convex identical unanimities in the groove of shell.Have on the shell for the plane of installing.

This fixator mainly is to utilize shell, inner core to constitute concavo-convex female surface and male surface and object elastic deformation within the specific limits, and plastic sheeting is stuck in the face of convex-concave.

Fig. 1, face of cylinder fixator cross sectional representation.

Fig. 2, fixator cross sectional representation that the face of cylinder is collapsible

Fig. 3, fixator cross sectional representation that prismatic surface is collapsible.

Below in conjunction with drawings and Examples content of the present utility model is described in further detail.

Fig. 1,2 is for being used for fixing the fixator of facility, and it mainly is that a mounting plane (4) is arranged on shell (1), guarantees steady and certain contact area, strengthens sealing, heat insulation effect.As window, greenhouse frame etc. are located, and also can be used as the usefulness of ceiling plastic sheeting furred ceiling.

Fig. 3 is the fixator of the use of the occasions such as joint connection between plastic sheeting.Concavo-convex section form can be varied.Can remove installed surface this moment.

(1) shell among the figure; (2) inner core; (3) bayonet socket; (4) installed surface.Shell (1) all adopts the plastics extrusion modling with inner core (2), and tone can be changeable, increases decorative effect, and light weight own is small and exquisite.

Shell (1) is an external member, and it utilizes Baltimore groove that internal member is formed dismountable fastening, location.Groove cross section can be circle, V-arrangement or other shape, no matter adopts which kind of form, and groove should have corresponding bayonet socket (3), guarantee inner core (2) can from bayonet socket (3) by, be pressed in the groove fixingly, inner core can be taken out from shell again when needing.Shell can be selected the stronger plastics of elasticity for use, makes as polyamide and so on.When adopting the fixator of band installed surface (4), shell is fixed on window frame or the Keelof green house with securing member or cementing agent gets final product.The use length of shell (1), inner core (2) can intercept arbitrarily as required.

Inner core (2) can be complete cylinder (pipe) or prism (pipe), also can be the section bar shape member that has the elastic dialing mouth that does not seal.The tubular structure that employing has an elastic dialing mouth is for well, and the one, weight reduction saves material, and is again to help installing chucking and dismounting by the elastic deformation of dialling mouthful.It is an internal member, and being contained of its cross section partly should be consistent with the containing partial shape of shell (1), and size should be more smaller than shell, leaves certain interval and hold plastic sheeting and loosening surplus.With the matching relationship of shell, assurance can tighten film, inner core can be taken out from shell again, and film gets loose.

Whether select shell (1) according to using needs with installed surface (4), then the plastic sheeting that will fix or connect wrap in the relevant position inner core (2) outer wall, push card jail in the outer casing groove together from the bayonet socket (3) of shell, plastic sheeting is between shell and the inner core, just can be along whole strip shell, inner core is fixed.

Compared with prior art, the utlity model has following advantage:

1. formation face contacts between plastic sheeting and fixator, sealing, high insulating effect, fixed, simple, laborsaving saving time;

2. fixator can use for a long time continuously, and dismounting does not all damage plastic sheeting, and plastic sheeting is easily fixing smooth, attractive in appearance, saves material, decrease cost.

Claims

1, a kind of fixator that is specially adapted to plastic sheeting, it is characterized in that it is made up of shell (1) and inner core (2), shell is the strip component that cross section is spill, inner core is the strip component that cross section is convex, inner core is located to be installed in the groove of shell by the bayonet socket (3) of shell, and male and fomale(M﹠F) coincide consistent.

2, fixator as claimed in claim 1 is characterized in that the cross section of said shell (1), inner core (2) is respectively round concave, convex shape.

3, fixator as claimed in claim 1 is characterized in that the cross section of said shell (1), inner core (2) is respectively V word concave, convex shape.
