Abstract

The utility model discloses a connector structure of a plastic greenhouse rack. A connector comprises a clamping groove and at least one casing pipe, wherein the clamping groove is formed by bending a metal plate into a U-shaped open grove and is provided with two side walls for correspondingly clamping and sleeving a longitudinal beam of the plastic greenhouse rack, and the casing pipe is a hollow metal casing pipe and is fixed on the side face of the clamping groove and used for the inserting arrangement of the lower end of an arch bar of the plastic greenhouse rack. By means of the connector, the longitudinal positioning steadiness and the transverse connection among all the arch bars are facilitated, and the mounted plastic greenhouse rack has the advantages of high integral strength, good stability, firmness and durability.

Description

Greenhouse frame link structure

Technical field

The utility model is meant a kind of link structure of greenhouse frame especially about the greenhouse frame that a kind of crops, vegetables and flower planting use.

Background technique

Adopt greenhouse frame, covered with plastic film can make in the canopy environment isolated with external environment on the frame, not only can keep out wind and rain, and also can produce greenhouse effect, builds the environment of suitable plant growth.A kind of big-canopy framework of commonly using, be by several arch bars, longeron and concrete column are in length and breadth to composition, this arch bar adopts metal tube to be bent to form the curved arc arch bar of certain span as ceiling, be that ground is fixed in the concrete column bottom during installation, and on the cylinder of top, offer open-work, use and intert fixing for this arch bar and longeron, the linkage structure of this arch bar and concrete column, make greenhouse frame in carrying, wind resistance, strength deficiency in the resistance to compression, and the open-work stress in order to fixedly arch bar and longeron on the concrete column is concentrated easy chipping, therefore, the utility model is not enough at this and improvement that do.

The model utility content

For this reason, the purpose of this utility model is to provide a kind of steadiness good, the greenhouse frame link structure that disassemble or assemble are quick and easy.

For reaching above-mentioned purpose, the technical solution of the utility model is:

A kind of greenhouse frame link structure, it is characterized in that: this link is made up of a draw-in groove and at least one sleeve pipe, this draw-in groove is bent into an inverted U opening groove by sheet metal, has the two side, longeron in order to corresponding cutting ferrule greenhouse frame, and this sleeve pipe is the metal sleeve of hollow, is fixedly arranged on the side of this draw-in groove, uses for the arch bar lower end of greenhouse frame and plants.

The bilateral symmetry of this draw-in groove respectively sets firmly a sleeve pipe.

The bottom, two side of this draw-in groove outwards expansion respectively forms a horizontal support face and respectively extends a locking face vertically downward, respectively is provided with lockhole on this two locking face.

This draw-in groove only is provided with sleeve pipe in a side, and this side sidewall bottom outwards expansion forms a horizontal support face and extends a locking face vertically downward, and the opposite side sidewall then extends a corresponding locking face straight vertically downward, respectively is provided with lockhole on this two locking face.

Adopt link of the present utility model, be used in the firm of each arch bar longitudinal register and laterally between expansion connect, laterally splice to enlarge the greenhouse frame area coverage or to split for arch bar, operate all very flexibly, easily and fast, and greenhouse frame bulk strength height, good stability after installing, sturdy and durable.

Embodiment

Shown in Fig. 1, be a kind of structural representation of greenhouse frame,, cover on this framework with plastic pellicle and can constitute a greenhouse frame for crops, vegetables and flower planting use in length and breadth to forming a framework by plural arch bar 1 and concrete column 2.Aforementioned plural arch bar 1 adopts metal pipe element to bend to arch circular arc, this plural number arch bar 1 and concrete column 2 is provided with between vertically at a certain distance at interval, and each arch bar 1 vertically is provided with longeron 3, laterally between each adjacent arch bar 1 and the longeron 3 is to realize being connected by greenhouse frame link 4 of the present utility model.

First embodiment of the utility model greenhouse frame link 4 structures is shown in Fig. 2, this link includes draw-in groove 41 and sleeve pipe 42, draw-in groove 41 is by the sheet metal bending and form an inverted U opening groove, has two side 411,412, and this draw-in groove 41 is in order to the longeron 3 of corresponding cutting ferrule greenhouse frame; Described sleeve pipe 42 is the metal sleeve of hollow, be fixedly arranged on the side of draw-in groove 41, present embodiment is the two side 411 at this draw-in groove, 412 symmetries respectively are provided with a sleeve pipe 42, this two sleeve pipe 42 is planted for the lower end of two adjacent arch bars 1 in the middle part of the greenhouse frame respectively, realize the connection between arch bar 1 laterally, cooperate shown in Figure 3 in concrete the use, can be only on the left side of draw-in groove 411 or right side, a sleeve pipe 42 be set, use for the arch bar of the greenhouse frame rightmost side or the arch bar plant location of the leftmost side, this sleeve pipe 42 can adopt welding with draw-in groove 41, mode such as bonding connects, also can be as Fig. 2, shown in 3 will draw-in groove 41 lower sidewall cut bending after hold this sleeve pipe 42 tightly, greenhouse frame utilize this link 4 can make each arch bar 1 vertically between the location firm and make things convenient for the expansion of arch bar 1 between laterally to connect.

Cooperate Fig. 4,5, shown in 6, be another embodiment of the present utility model, include draw-in groove 41 and sleeve pipe 42, with the bilateral symmetry of draw-in groove one sleeve pipe 42 being set respectively is that example explains, with aforementioned different be, the two side 411 of this draw-in groove 41, the outside expansion in 412 bottom respectively forms a horizontal support face 413,414 also extend two parallel locking faces 415 vertically downward, 416, this horizontal support face 413,414 in order to support fixation sleeve pipe 42, this two locking face 415, respectively be provided with lockhole 417 on 416,418, pass lockhole 417 by the lock firmware (not shown), 418 can be locked in link of the present utility model on one concrete column 2.

As shown in Fig. 7,8, be another embodiment of the present utility model, use for the arch bar location of the greenhouse frame rightmost side or the leftmost side and use, only the side (left side or right side) in this draw-in groove 41 is provided with sleeve pipe 42, and outwards expand in the bottom that this draw-in groove 41 is provided with a side sidewall of sleeve pipe 42 and to form a horizontal support face and to extend a locking face vertically downward, the opposite side sidewall then extends a corresponding locking face straight vertically downward, respectively be provided with lockhole on this two locking face, passing lockhole by lock firmware can be locked in link on one concrete column 2.

As seen above-mentioned, greenhouse frame link 4 of the present utility model, help each arch bar 1 between vertically strong fix and laterally between expansion connect, laterally splice for arch bar and to enlarge the greenhouse frame area coverage or split, operate all very flexibly, easily and fast, and greenhouse frame bulk strength height, good stability after installing, sturdy and durable.
