Description

A inside lining protection device for centre gripping covering material's warmhouse booth draw-in groove

Technical Field

The utility model relates to an farming big-arch shelter technical field especially relates to an inside lining protection device that is used for centre gripping covering material's warmhouse booth draw-in groove.

Background

The greenhouse covering material (film or sunshade net) is affected by high temperature and strong ultraviolet irradiation, the mechanical performance is reduced after 1-3 years of use, and the covering material at the joint of the greenhouse structure is directly clamped by the metal clamp spring and is often the position of the whole film which is most prone to aging and damage. The main reason is that the covering material is fixed by the clamp spring and the clamping groove, the traditional clamp spring clamping groove is generally made of metal materials, the metal materials are heated quickly by solar irradiation, the temperature in summer can reach 70 ℃ at most, and therefore the aging of the covering material is accelerated by the clamp spring clamping groove with high temperature.

In addition, when the covering material rocks about receiving the wind load effect, still can frequently rub with metal jump ring oral area, traditional jump ring draw-in groove centre gripping only relies on jump ring elastic tension to support fixed film, and whole contact surface line nature atress, stress concentration are in the jump ring fixed position, not by the homodisperse, not only cause local fatigue, the ageing of material, and wind-force is too big or the improper time of installation still can appear the jump ring and take off the groove, the problem that covering material was lifted. Therefore, the protection of the contact point between the covering material and the greenhouse structure has a great influence on the service life of the whole covering material, and the extension of the service life of the covering material at the clamped part is equivalent to the extension of the service life of the whole covering material.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1, an inner lining protection device for a greenhouse clamping groove for clamping a covering material comprises a clamping groove body 1, a wrapping layer 2, an inner lining layer 3 and a clamp spring 5, wherein the wrapping layer 2 is generally made of a plastic material, such as plastic skin, and the thickness of the wrapping layer 2 is generally 0.15-0.30 mm; the inner liner 3 is made of rubber materials, such as rubber strips, and the thickness of the inner liner 3 is generally 0.5-0.8 mm. Draw-in groove body 1 is U-shaped opening draw-in groove, parcel 2 wraps up at the surface of draw-in groove body 1, inner liner 3 sets up in the U-shaped opening of draw-in groove body 1, covering material 4 is by the centre gripping between inner liner 3 and parcel 2, jump ring 5 matches in the U-shaped opening of draw-in groove body 1 and is used for chucking inner liner 3, general draw-in groove body 1 has certain length, consequently jump ring 5 also has corresponding length and alternates the block in the U-shaped opening of draw-in groove body 1, jump ring 5 generally adopts to have metal material to make here, certain elasticity has simultaneously, so that in a flexible way penetrate draw-in groove body 1 or dial out draw-in groove body 1. Wrapping layer 2 has the cooling effect to draw-in groove body 1, has thermal-insulated effect to covering material 4, avoids under the sunlight irradiation draw-in groove body 1 to heat up too fast. The inner liner layer 3 blocks the cover material 4 from directly contacting with the clamp spring 5 of metal, meanwhile, the cover material 4 can be accurately fixed, when the cover material 4 shakes left and right under the action of wind load, direct friction between the cover material 4 and the metal surface of the clamp spring 5 is avoided, the linear stress of the cover material 4 can be converted into surface layer stress by accurate lamination of the inner liner layer 3, the stress is evenly distributed, local damage caused by stress concentration is avoided, meanwhile, the inner liner layer 4 is made of rubber materials with poor heat conductivity, the inner surface of the clamp groove body 1 is laminated, the clamp groove body is not loosened when expanding with heat and contracting with cold, and the clamp groove does not fall off under natural; therefore, the inner liner 3 can play a role in protecting the covering material 4, so that the aging of the covering material is delayed, the inner liner is convenient to disassemble and durable, and the service life of the inner liner can be 4-6 years. The utility model discloses traditional metal jump ring and cover material 4 directly fixed mode have been changed to in more firm, more stably the centre gripping cover material 4, and play effectual guard action to cover material 4, effectively prolong cover material 4's life-span.

As shown in fig. 2, in a preferred embodiment, the card slot body 1 includes an elastic clamping portion 11 and an engaging portion 12, which are integrally formed, the engaging portion 12 is engaged with the snap spring 5, the elastic clamping portion 11 is used to block the outward deviation of the snap spring 5, so that the snap spring 5 is better engaged and clamped with the engaging portion 12, a joint between the elastic clamping portion 11 and the engaging portion 12 is generally set to be smooth, two sides of the bottom of the engaging portion 12 are circular arcs (shown as inward concave left and right in fig. 1), and naturally, two ends of the snap spring 5 are also circular arcs (shown as outward convex left and right in fig. 1), which is beneficial to continuity and stability when the card slot body 1 engages the snap spring 5. In addition, as shown in fig. 3 and 4, the snap spring 5 is bent to extend in the length direction in the U-shaped opening of the clamping groove body 1, so that the lining layer 3 and the wrapping layer 2 can better clamp the covering material, and the material used by the snap spring 5 is saved.

In conclusion, adopt the utility model provides a inside lining protection device for centre gripping covering material's warmhouse booth draw-in groove has changed traditional metal jump ring 5 and covering material 4 and has directly carried out the fixed mode, increases parcel layer 2 and inner liner 3 to in more firm, more stably grasp covering material 4, and play effectual guard action, effectively prolong covering material 4's life-span to covering material 4.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
