Hard film fixing device in greenhouse

Abstract

The present invention relates to a hard film fixing device for a greenhouse, capable of quickly, conveniently, and tightly fixing a hard film or conveniently separating the film. According to the present invention, the hard film fixing device comprises: a loop frame (10) including a fixing groove part (14) formed on the upper surface with both open ends and an open upper part; a combination unit (20) including first and second combination members (21, 22) to insert a hard film into the fixing groove part; and a cover member (30) combined to widen left and right gaps of the first and second combination members in the upper direction to cover the upper middle part of the first and second combination members while fixing the first and second combination members so that the first and second combination members are able to tightly and firmly combine the hard film with the fixing groove part. As such, the present invention is capable of considerably reducing the time and costs for corresponding work.

Description

technical field [0001] The invention relates to a dura mater fixing device for a greenhouse, in particular to a temperature dura mater fixing device which can more quickly and conveniently tighten and firmly combine and fix the dura mater or separate it easily. Background technique [0002] The existing dura mater fixation device is the top dura mater fixation structure of the dura mater greenhouse that the applicant has applied for registration (Registration Korean Utility Model No. 20-0344756), which is set on the upper ends of multiple vertical pillars. A plurality of top frames are arranged on the shelf, and a pair of top frames in these top frames are provided with "┤"-shaped protrusions formed by horizontal parts and vertical parts on both sides of the inner bed part, and will be close to the protrusions. The top dura mater at the outlet is fixed with a fixing frame that is provided with an engaging ridge that is stuck on the top of the vertical part, and is tightened ...

AI Technical Summary

Problems solved by technology

[0003] However, the fixation and combination of the top dura mater is that after the top dura mater is closely attached to the "┤" shaped protrusion, the fixing frame is combined so that the snap-fitting is stuck on the top of the vertical part, but the fixing frame cannot fix the top hard layer. The membrane is completely and firmly fixed on the protrusion, so it is tightened and fixed with multiple twisting screws, but not only at the time of twisting, but also when unscrewing the screws in order to disassemble the greenhouse for partial repair or replacement, time, manpower and cost are required bigger

[0004] In addition, if the screw is tightened and then unscrewed again, the screw hole of the fixing frame or the twisted part of the clamping groove on the protrusion that has been screwed through the screw is easy to loosen, and the top dura can not be firmly fixed on the protrusion, and the top is hard. There are many screw holes on the film, which cannot be reused, resulting in a shortened lifespan and a waste of resources and costs. At the same time, the twisted screws are exposed to the outside, which will further reduce the durability and product value.
