Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Refering to shown in Fig. 2 to Fig. 5, a kind of greenhouse sealing structure, including cross bar 1, upright bar 4 and shell 7, cross bar 1 are welded on
4 top of upright bar, 7 front and back side of shell is fixed with bearing 2 and is equipped with through-hole 5 and waist-shaped hole 6 simultaneously, each in bearing 2 and through-hole 5
It is placed with a rotatable shaft 3, is fixed with idler wheel 13 and sheave 8, the shaft built in through-hole 5 in the shaft 3 built in bearing 2
It is fixed with coupled wheel 10 on 3, transmission belt 9 is connected between sheave 8 and coupled wheel 10, oscillating rod 16 is built-in on waist-shaped hole 6, puts
Locking wheel 11 is fixed in lever 16,16 medial side of oscillating rod is further fixed on loop bar 14, spring 12 is placed in loop bar 14.
Upright bar 4 is vertically arranged, and its bottom end is pyramidal structure, can be parallel with external greenhouse strut, and bottom can insert
Enter stronger into ground bottom.The both ends diameter of coupled wheel 10 is greater than intermediate ends diameter, and is additionally provided on the end of the left and right sides interior
Slot 15, on inside groove 15, other end set is buckled on sheave 89 one end hitch of transmission belt, the cross bar of idler wheel 13 and greenhouse drive film
Rotation is contacted and driven, sheave 8 is made to drive coupled wheel 10 to rotate indirectly by transmission belt 9 and is moved up and down in upright bar 4.Locking
Wheel 11 is conical structure, and one is respectively rotatably connected on 16 or so side of oscillating rod, and the diameter among locking wheel 11
Less than outside diameter, for mutually clamping upright bar 4 with coupled wheel 10 so that it will not falling and follow Greenhouse cross bar to rotate
It moves up and down.It is hollow structure in loop bar 14, and one end of the spring 12 contradicts in loop bar 14, the other end is then contradicted in shell
At the right side inner wall of body 7, oscillating rod 16 is equipped with spring 12, and the left and right end in waist-shaped hole 6 of oscillating rod 16 can be made mobile
Adjusting elasticity, making it that can clamp upright bar 4 more easily will not clamping when also can move up and down.Transmission belt 9 be belt or
Chain or other linkage connectors.
In the present embodiment, overlay film cross bar 17 drives overlay film to rotate counterclockwise, and overlay film cross bar 17 will drive idler wheel after rotating
13 rotate clockwise, and idler wheel 13 makes sheave 8 also link clockwise after rotating clockwise, and are then made by the transmission of transmission belt 9
Coupled wheel 10 also links clockwise, meanwhile, it is in clamped condition in the two sides of upright bar 4 between coupled wheel 10 and locking wheel 11
Also, when coupled wheel 10 rotates, entire shell 7 can be driven up to move in state can be moved up and down simultaneously, therefore, overlay film is horizontal
Bar 17 has the limitation of entire shell 7 and the inside components, is not in excessive rotation angle, overlay film cross bar 17 will not
Because it is stuck caused by transition bending or entirely cannot distracted situation completely, make it that can play itself effect completely.
Wherein, the shaft 3 on bearing 2 and linkage rotation is interference fitted between bearing 2, the shaft 2 in through-hole 5 then with through-hole
5 can clearance fit, a needle bearing can also be fixed in through-hole 5, shaft 2 and needle bearing are interference fitted, coupled wheel 10
It is fixed to each other with the shaft 2 in through-hole 5, oscillating rod 16 can swing setting in waist-shaped hole 6, by waist-shaped hole 6
Between spring 12 cooperate, make locking wheel 11 on oscillating rod 16 that there is certain tensile force, and locking wheel 11 and oscillating rod 16 it
Between be it is mutually rotatable, locking wheel 11 is constantly in clamped condition, but locking wheel 11 can be scrolled up and down along upright bar 4.
This device is mountable on the maximum position of 17 curvature of overlay film cross bar, if there is two or more bendings, at most
Installation two i.e. its rectifiable curvature, shell 7 are all rounded structure close to 17 side of overlay film cross bar, main purpose be in order to avoid
Wedge angle cuts overlay film, and 7 lower end side of shell is hollow structure.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work should all be covered subject to scope of protection of the utility model.
