Embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly and completely describe.

The band list of the utility model as shown in Figure 1 to 11 hooks the brooder clamping device of spring fastener, it is by Spring Card 20 composition of folder 10 and brooder folder.The outside of brooder folder 20 has the first arc groove 21, the second arc groove 22 and locating slot 23, which connects 21 and second arc groove 22 of the first arc groove, and the locating slot 23 is recessed perpendicular to the first arc Plane where 21 and second arc groove of groove 22, the shape of groove is consistent with the shape of spring fastener 10, effectively to spring Clip 10 is coated, and is reduced spring fastener 10 and is acted on by other external force.

Spring fastener 10 is by the first segmental arc 11, the second segmental arc 12 and connects 11 and second arc of the first segmental arc The positioning section 13 of section 12 forms, and the first segmental arc 11, the second segmental arc 12 and positioning section 13 are located at the first arc groove respectively 21st, in the second arc groove 22 and locating slot 23.The lateral wall of brooder folder 20 is connected through a lead-in chamfered 24 with locating slot 23, Lead-in chamfered 24 protrudes from the lateral wall of brooder folder 20, can facilitate spring fastener 10 being caught in locating slot 23, ensure that at the same time Positioning section 13 is stably fixed in locating slot 23 by the protrusion of lead-in chamfered 24.

The material that spring fastener 10 uses is the stainless steel wire or high-carbon steel wire of 1.0 ~ 3.0mm of diameter.It is economical same When ensure that spring fastener 10 has preferable intensity and elasticity.The radius of curvature of first segmental arc 11 and the second segmental arc 12 is R5~R20mm.The clamping stability of spring fastener is preferable within this range.

Spring fastener 10 is embedded in brooder and presss from both sides in 20 grooves, it is not easy to and it is subject to other external force to act on, it is beautiful and practical.Installation When, preferentially positioning section 13 is installed in locating slot 23, then one by one blocks the first segmental arc 11 and the second segmental arc 12 Enter in the first arc groove 21 and the second arc groove 22, easy for installation, brooder is pressed from both sides in double segmental arcs design of spring fastener 10 20 provide stabilization clamp holding force, are not easily disconnected from, solid and reliable, and have good elasticity.

With reference to Fig. 5 to Figure 10, the inner side of brooder folder 20 has stent receiving portion 25, and the end of stent receiving portion 25 has arc Shape face.Arcwall face is made of the first arcwall face 251 and the second arcwall face 252, the first arcwall face 251 and the second arcwall face 252 to Stent receiving portion 25 protrudes, and distance therebetween is less than the spacing of the part of the arcwall face corresponding to stent, effective guarantee Brooder folder 20 is stably fixed on stent, is fixed without screw, quick and easy for installation.

After greenhouse covers film, it should be pushed down immediately with brooder folder 20.One clamping device, tool generally are set every 1~2m Body is set according to local weather situation, the big environment of wind, and clamping device is installed more intensive.This clamping dress of the utility model The spring fastener 10 put uses unclosed double segmental arc method of clamping, it plays with good elasticity and reinforce brooder folder 20 Effect, and allow brooder folder 20 to keep lasting intensity and elastic force, so as to ensure that the elastic appropriateness of press mold, while spring fastener 10 positioning section 13 is installed on one side windward, prevents strong wind from blowing greenhouse film and causing clamping device to come off.Preferably, according to The number of different wind directions and the frequency of size, determine the installation direction of the positioning section 13 of installation spring fastener 10, can be wrong successively Open installation, but need ensure wind direction number and big small frequency it is high one side installation positioning section 13 number more than frequency it is low one Face.It not only ensure that brooder presss from both sides the stability of 20 press molds, spring fastener 10 is not easily to fall off, solid and reliable, also has safety Property, the double arcuate structures designs of clamping device have good elastic performance, ensure that the elastic appropriateness of brooder 20 press molds of folder, Can be from main regulation in a certain range, it is ensured that canopy film will not be broken by big wind.

Greenhouse film generally has the characteristics that thin and lightweight, should be noted to ensure that brooder folder 20 has one when clamping Fixed holding area and the finish of contact surface, if holding area is small, brooder folder 20 and the unit that is subject to of greenhouse film The power of area is bigger, and brooder folder 20 is more easily separated from stent, so as to cause greenhouse film to loosen, is easily broken by the wind, or even directly Connect and cause greenhouse film contact surface is coarse by 20 phenomenons that penetrate of brooder folder, when being blown by wind brooder folder 20 and stent it Between produce friction greenhouse film can be caused to damage.First arcwall face 251 and the second arcwall face 252 use arc-shaped curved surface structure, It can be good at being attached on greenhouse bracket cylindrical surface, its contact area is big, and highly polished, avoids greenhouse film because friction And damage.

Greenhouse film is tightly coated in stent steel cylindrical tube by this brooder folder 20 of the utility model, is pacified without screw Dress, conveniently removes and installs, and avoids and greenhouse film is fixed improper and caused damage, improves its service life, do not influence secondary Use, it is cost-effective.Double segmental arcs design of spring fastener 10 increases the grip strength of brooder folder 20, while causes brooder folder 20 have good elasticity.Greenhouse film is not easy to loosen, and good guarantee is provided for the security of canopy film.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this The spirit of utility model and any modification within principle, made, equivalent substitution and improvement etc., should be included in the utility model Protection domain within.
