[0001] The utility model relates to a greenhouse pipe connecting technical field, concretely is a greenhouse pipe connecting device. BACKGROUND

[0002] In agricultural production, the greenhouse is widely used in the planting of vegetables, fruits and other crops to provide suitable growth environment, realize the anti-season cultivation and improve the yield and quality. The framework of the greenhouse is usually built by a plurality of greenhouse pipes, and these greenhouse pipes need reliable and convenient connecting mode to build stable greenhouse structure.

[0003] The traditional greenhouse pipe connecting device does not have a special supporting structure, and the longitudinal pipe of the greenhouse mainly bears the weight of the top of the greenhouse and the pressure applied by the external environment, such as the weight of accumulated snow, the lateral force of wind blowing, etc. Due to the lack of effective support, the longitudinal pipe is prone to deformation when bearing these loads, resulting in the collapse of the top of the greenhouse. SUMMARY

[0004] The utility model intends to provide a greenhouse pipe connecting device to solve the problems raised in the above background.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A greenhouse pipe connecting device, comprising an arch pipe, a longitudinal pipe and a supporting pipe, the longitudinal pipe is sleeved with a transverse connecting pipe, the transverse connecting pipe is connected with a vertical connecting pipe, the supporting pipe is detachably connected with the vertical connecting pipe, the transverse connecting pipe is connected with a connecting frame, the connecting frame is rotatably connected with a semicircular cover, the semicircular cover and the connecting frame are provided with a threaded hole in common, a fixing bolt is threadedly connected with the inner wall of the threaded hole, the arch pipe cooperates with the semicircular cover and the connecting frame, the vertical connecting pipe is movably connected with a supporting piece, the supporting piece is rotatably connected with a supporting rod, the supporting rod is rotatably connected with a limiting piece, the limiting piece is movably connected with the longitudinal pipe, the supporting piece and the limiting piece are respectively threadedly connected with locking bolts, and the two locking bolts are matched with the vertical connecting pipe and the longitudinal pipe respectively.

[0007] Preferably, the transverse connecting pipe and the vertical connecting pipe are respectively threadedly connected with limiting bolts, the longitudinal pipe and the supporting pipe are respectively provided with limiting holes, and the limiting bolts and the limiting holes are threadedly connected.

[0008] Preferably, the semicircular cover is threadedly connected with a screw rod, the screw rod is rotatably connected with a limiting plate, and the limiting plate abuts against the arch pipe.

[0009] Preferably, the screw rod is threadedly connected with a fixing piece.

[0010] Preferably, the transverse connecting pipe, the vertical connecting pipe, the connecting frame and the semicircular cover are made of glass fiber reinforced plastic.

[0011] The technical scheme compared with the prior art produces beneficial effects:

[0012] (1) The present scheme provides additional support to the vertical pipe by setting up support pieces, support rods, limit pieces and locking bolts, which can greatly improve the stability of the greenhouse under extreme wind conditions and reduce the risk of the greenhouse being blown down. At the same time, it shares the vertical downward weight borne by the vertical pipe, such as the covering material on the top of the greenhouse, snow and the like, effectively preventing the vertical pipe from collapsing due to snow pressure and ensuring the overall structural integrity of the greenhouse. Good load transfer can ensure the stress balance of the entire greenhouse structure, reduce structural damage caused by local overload, and prolong the service life of the greenhouse. And through the adjustment of the fastening degree of the locking bolt, it can adapt to the stress changes of the greenhouse vertical pipe under different seasons and weather conditions. For example, in summer, only the bolt needs to be tightened properly to provide basic stability; while in winter or before severe weather arrives, the bolt can be further tightened to increase the support strength and ensure the safety of the greenhouse.

[0013] (2) By setting the limit bolt and the limit hole, additional fixing points are provided for the vertical pipe and the support rod to prevent displacement of the vertical pipe and the support rod, thereby maintaining the integrity and stability of the entire greenhouse frame, reducing the risk of the greenhouse being blown down or structural deformation, prolonging the service life of the greenhouse pipe connecting device and the entire greenhouse, reducing the frequency of maintenance and replacement of the greenhouse, and reducing long-term operating costs.

[0014] (3) By setting the screw rod and the limiting plate, it can adapt to different specifications of the arch pipe to achieve stable connection, greatly improving the versatility of the connecting device in different greenhouse projects and reducing the need for multiple special connecting components. Only by using the adjustability of the screw rod and the limiting plate, the connection state can be quickly adjusted on site to save a lot of time and labor cost, improve the overall construction speed of the greenhouse, make the greenhouse put into use faster, and reduce the delay of agricultural production caused by long installation period.

[0015] (4) By setting the fixing piece, the displacement of the screw rod is prevented, the accuracy of the adjustment can be continuously and effectively ensured, the reliability of the greenhouse structure is improved, and the wear between the screw rod displacement and the surrounding components is reduced, so that the screw thread of the screw rod remains in good condition, prolonging the service life of the screw rod itself and related components cooperating with it.

[0016] (5) By setting the transverse connecting pipe, vertical connecting pipe, connecting frame and semicircular cover for glass steel material, glass steel material itself has strong corrosion resistance, can be exposed in these complex and corrosive environment for a long time without being easily corroded, keep the integrity of the structure and stable performance, greatly prolong its service life, reduce the corrosion caused by frequent replacement and maintenance costs.

DETAILED DESCRIPTION

[0020] The utility model will be further explained in detail in combination with the drawings and embodiments:

[0021] As Figs. 1-2The illustrated greenhouse pipe connecting device comprises an arch pipe 5, a longitudinal pipe 3, a horizontal connecting pipe 4, a vertical connecting pipe 14, a support pipe 16, a connecting frame 11, a semicircular cover 9, a fixing bolt 10, a support piece 15, a support rod 12, a limiting piece 2, a locking bolt 1, a limiting screw 13, a limiting hole 17, a screw rod 7, and a limiting plate 6. The horizontal connecting pipe 4 is connected with the vertical connecting pipe 14, and the vertical connecting pipe 14 is detachably connected with the support pipe 16. The horizontal connecting pipe 4 is connected with the connecting frame 11, and the connecting frame 11 is rotatably connected with the semicircular cover 9. The semicircular cover 9 is provided with a threaded hole 18 on the right side of the connecting frame 11. The threaded hole 18 is threadedly connected with the fixing bolt 10. The arch pipe 5 is matched with the semicircular cover 9 and the connecting frame 11. The semicircular cover 9 is opened by rotating, and then the arch pipe 5 is placed on the connecting frame 11. The semicircular cover 9 is rotated and fixed by the fixing bolt 10. The outer wall of the vertical connecting pipe 14 is movably connected with the support piece 15. The support piece 15 is rotatably connected with the support rod 12 at both ends. The support rod 12 is rotatably connected with the limiting piece 2. The limiting piece 2 is movably connected with the outer wall of the longitudinal pipe 3. The support piece 15 and the limiting piece 2 are threadedly connected with the locking bolt 1. The locking bolt 1 is matched with the vertical connecting pipe 14 and the longitudinal pipe 3. The locking bolt 1 is tightened to gradually press the outer wall of the vertical connecting pipe 14. The friction between the support piece 15 and the vertical connecting pipe 14 gradually increases with the tightening of the locking bolt 1, until the degree of rotation and displacement of the support piece 15 relative to the vertical connecting pipe 14 is limited, so as to realize the accurate locking of the position of the support piece 15. The use mode of the locking bolt 1, the limiting piece 2 and the longitudinal pipe 3 is consistent with the use mode of the locking bolt 1, the support piece 15 and the vertical connecting pipe 14. The horizontal connecting pipe 4 and the vertical connecting pipe 14 are threadedly connected with the limiting screw 13. The longitudinal pipe 3 and the support pipe 16 are provided with the limiting hole 17. The limiting screw 13 and the limiting hole 17 are threadedly connected, so that the horizontal connecting pipe 4 and the vertical connecting pipe 14 are tightly connected with the longitudinal pipe 3 and the support pipe 16 respectively, forming an additional constraint point, which can effectively resist the interference of natural factors (such as wind, vibration, etc.) or human factors (such as collision of agricultural operation, etc.), so as to maintain the integrity and stability of the whole greenhouse frame, and reduce the risk of blowing down or structural deformation of the greenhouse. The inner wall of the top of the semicircular cover 9 is threadedly connected with the screw rod 7. The bottom of the screw rod 7 is rotatably connected with the limiting plate 6. The limiting plate 6 is in contact with the arch pipe 5. The screw rod 7 is twisted to move downward until the limiting plate 6 is in contact with the arch pipe 5 to limit the arch pipe 5. The screw rod 7 is threadedly connected with the fixing piece 8. The screw rod 7 is tightly locked and cannot be easily loosened or shifted by tightening the fixing piece 8. The horizontal connecting pipe 4, the vertical connecting pipe 14, the connecting frame 11 and the semicircular cover 9 are made of glass steel. In the use environment of the greenhouse, various corrosive factors such as humid air, acid and alkali components in the soil, fertilizer and pesticide residues, and rainwater erosion often occur. The glass steel material itself has strong corrosion resistance and can be exposed to these complex and corrosive environments for a long time without being easily corroded and rusted.

[0022] The specific implementation process is as follows:

[0023] By sleeving the transverse connecting pipe 4 on the outer wall of the longitudinal pipe 3, sleeving the limiting member 2, placing the support pipe 16 into the vertical connecting pipe 14, then screwing the limiting bolt 13 into the limiting hole 17 to limit the longitudinal pipe 3 and the support pipe 16, then placing the arch pipe 5 on the connecting frame 11, rotating the semicircular cover 9 to cover the arch pipe 5, then screwing the fixing bolt 10 into the threaded hole 18, finally screwing the screw 7 to drive the limiting plate 6 to move downward until it abuts against the arch pipe 5 to limit the arch pipe 5. The relative position relationship between the longitudinal pipe 3 and the vertical connecting pipe 14 is observed continuously to ensure that there is no obvious interference or unreasonable stress point between the components, and when the positions of the components are roughly determined, the precise limiting operation is started. First, the locking bolt 1 threaded on the support member 15 is tightened using a tool, and as the bolt is gradually tightened, the support member 15 will gradually press tightly against the outer wall of the vertical connecting pipe 14 to generate sufficient friction force to limit the upward and downward movement and rotation of the support member 15 on the vertical connecting pipe 14. During the tightening process, the fit of the support member 15 and the vertical connecting pipe 14 is observed to ensure that the bolt is uniformly tightened and the support member 15 is stably fixed at the predetermined position. Then, the locking bolt 1 threaded on the limiting member 2 is tightened to tightly press the limiting member 2 against the outer wall of the longitudinal pipe 3. The friction force generated by the pressure of the bolt limits the sliding and rotation of the limiting member 2 relative to the longitudinal pipe 3, thereby determining the relative position relationship between the longitudinal pipe 3 and the support rod 12 and the support member 15. When the locking bolt 1 of the limiting member 2 is tightened, attention should also be paid to uniformity, and the longitudinal pipe 3 should be checked to see if it is in the correct position and if there is any deformation or displacement due to the tightening of the bolt.

[0024] The above is only an embodiment of the present application, and common technical solutions and / or characteristics in the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
