Abstract

The utility model discloses a plastic greenhouse inner-placed curtain rolling device, including upper guide wheels (15) in the upper end of the plastic greenhouse, lower guide wheels (12) in the lower end, rolling ropes (3) arranged between the upper guide wheels (15) and the lower guide wheels (12), and a rotating device connected with the upper guide wheels (15). The utility model is characterized in that the slide blocks (9) are connected with the rolling ropes (3) with intervals, guide rails (5) are matched to the slide blocks (9), inner membranes (16) are connected with the lower side of the slide blocks (9), and a fixing clip hoop is connected with the upper side of the guide rails (5). When using the device, a layer inner membrane is arranged under the inner side membrane in the plastic greenhouse, and a double layer structure is formed by the two membranes, between which a heat preservation layer is formed, so as to solve the problem of the plastic greenhouse heat preservation at night. At day the drive guide wheels rotate to drive the rolling ropes and the slide blocks move along the guide rails, so as to collect the inner membranes in the upper side of the inner side, thus a single membrane is formed. The utility model has the advantages that operation is convenient, grass curtains are saved, rain and snow doesn't influence the device, and materials can't be corrupted, as well as having a long service life, saving nature resources with low cost.

Description

The built-in roller blind device of booth

Technical field

The utility model relates to a kind of roller blind device, and the built-in roller blind device of particularly a kind of booth is located at the insulation that the greenhouse film inboard is used for booth with this device.

Background technology

Booth all needs attemperator, existing heat preserving mode is the straw screen or mat insulation, structure is: in the greenhouse film outside straw screen or mat is installed, and cooperate coiling by rope and the upper block that is positioned at booth top and the lower tumbler that is positioned at the booth below, deposit at the top that makes straw screen or mat twist in booth daytime, and can open straw screen or mat the outside covered at greenhouse film in the time of need being incubated night, the volume of straw screen or mat is put by electronic or hurdy-gurdy and is finished, and also has to adopt manual type.Its shortcoming is as follows: the cost height, waste natural resources, and not moisture resistance, perishable, poor reliability, the life-span is short, and sleet sky volume is put difficulty, and the straw screen or mat volume behind the volume is big, easily film is caused damage in operating process.

Summary of the invention

The purpose of this utility model provides that a kind of cost is low, moistureproof, film, the long built-in roller blind device of booth of life-span are put easily, do not injured in without putrefaction, volume, overcomes the deficiencies in the prior art.

The built-in roller blind device of booth of the present utility model, it comprises the upper block that is positioned at booth upper end and the lower tumbler of lower end, between upper block and lower tumbler, be provided with serving, upper block switches through moving device, it is characterized in that: serving is connected with slide block at interval, be furnished with guide rail mutually with slide block, the below of slide block is connected with inner membrance, and the guide rail top is connected to the installation clip.

The built-in roller blind device of booth of the present utility model is provided with roller between wherein said slide block and the described guide rail, and described roller is contained on the two side ends axle of slide block.

The built-in roller blind device of booth of the present utility model is provided with bearing between wherein said roller and the slide block.

The built-in roller blind device of booth of the present utility model, the below of wherein said slide block is connected to connecting rod, and the bottom head of connecting rod connects intermediate plate and lower clamping piece, and described inner membrance is clipped between upper clip and the lower clamping piece.

The built-in roller blind device of booth of the present utility model, wherein said installation yoke configurations is: the top of guide rail is connected to dowel, and termination lower catch hoop on the dowel is furnished with front band mutually with lower catch hoop.

The built-in roller blind device of booth of the present utility model can be provided with one deck inner membrance below the booth internal membrane, inner membrance becomes double-decker with thin type, become air heat insulating layer in the middle of it, solved the problem of booth thermal insulation at night, can drive guide wheel by crank and rotate daytime, drive serving and slide block and move, make inner membrance concentrate on the booth inside front, form monofilm along guide rail, easy to operate, saved straw screen or mat, be not subjected to the influence of sleet, material is stale-proof, life-span is long, has saved natural resources, and cost is low.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is an A-A sectional schematic diagram shown in Figure 1.

Embodiment

As shown in the figure: 1 is body of wall, and 2 is the bracing frame of booth top, above bracing frame 2 film is installed, and this part is the prior art part, no longer describes in detail.5 is guide rail, the section of guide rail 5 is in the form of slot, Open Side Down is provided with, above guide rail 5, be connected to the installation clip, its structure is: be welded with dowel 6 above the guide rail 5, dowel 6 upper ends are welded with lower catch hoop 7, are connected with front band 8 with lower catch hoop 7 bolts, front band 8 fastens the back with lower catch hoop 7 and forms the hole in the centre, just is fastened on the bracing frame 2.Above-mentioned installation clip is a plurality of, evenly distributes, and guide rail 5 is lifted on the below of bracing frame 2.Be provided with slide block 9 in guide rail 5 inboards, on the end axle of the both sides of slide block 9 bearing 4 be housed, roller 10 is equipped with in bearing 4 outsides, by roller 10 slide block 9 is slided in guide rail 5.

Below slide block 10, be welded with connecting rod 11, connecting rod 11 extend out to the below of guide rail 5, be connected with upper clip 14 and lower clamping piece 13 at the bottom of connecting rod 11 head thread, connecting rod 11 penetrates inner membrance 16 backs by upper clip 14 and lower clamping piece 13 clamping inner membrances 16, described inner membrance 16 can be for individual layer, also can be for bilayer, can satisfy the needs of different regions.Above-mentioned slide block structure is many groups, is distributed on the guide rail 5.
