Abstract

A coping spring is made of an irregular steel wire and is used in a greenhouse. The coping spring facilitates building of greenhouses.

Description

A kind of spring that bears down on one

Technical field

The design is relevant with green house.

Background technology

At present, the plastic greenhouse that generally uses is single layer structure, and heat-insulating property is relatively poor, fills in cold winter in the north, in order to keep temperature suitable in the booth, night is added a cover cotton-wadded quilt or straw screen or mat etc. at plastic film in people or the heating of consumption mass energy perhaps, raises daytime and gets sun, cause plastic film and straw screen or mat etc. very easily impaired, both increased consumer spending, again waste of manpower brings many worries to the peasant.Improve the booth room temperature in order to take full advantage of daylight, reach and save the heating energy winter, ' spring and autumn shifts to an earlier date or postpones the vegetables Time To Market, and the glasshouse big shack with double films technical scheme that is made of inner membrance beam and adventitia beam has appearred in the purpose of increasing economic efficiency., and reduced cost.But, feel in the practice to stretch the phenomenon that occurs the wearing and tearing plastics when using when the both sides of two film beams outward opening, also exist to be subjected to the not high shortcoming of force intensity.

The utility model content

The problem that exists in order to solve tradition, the utility model provides following technical scheme to be:

A kind of spring that bears down on one is comprised of the metal steel wire, and described metal steel wire has very strong pliability.

The beneficial effect that the utility model brings is:

Because the metal steel wire has been adopted in design, can be more effective, precisely firmly block green house, also easily take simultaneously.

Description of drawings

Fig. 1 is design example.

Among the figure: 1 is jump ring.

Embodiment

The steel band of the certain elasticity of tool and intensity folding nest is become the jump ring line, as among Fig. 11, respectively two ends are folded into, so just, formed such as the jump ring among Fig. 1, recessed above it, middle flat, below two ports amount to into, reaching firmly purpose of clamping, light meaning can not break away from.

The above; it only is one of embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; variation or the replacement that can expect without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.

Claims (1)

1. the spring that bears down on one is comprised of the metal steel wire.
