Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model.

In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1 to 4, an embodiment of the present invention provides a fastening member for connecting greenhouse rod members, including: two lower links 1 and one upper link 2. The two lower connecting pieces 1 are identical in structural shape and are arranged in parallel and symmetrically. The upper connecting piece 2 is connected to the top end of the lower connecting piece 1, and the upper connecting piece 2 comprises a base 21 and two supporting side edges 22. The base 21 and the support sides 22 are recessed support grooves for supporting the rain gutter.

Specifically, a vertical column groove 11 with a downward opening is arranged between the two lower connecting pieces 1 and is used for a supporting seat of the vertical column. Meanwhile, two arch bar grooves 12 are further arranged between the two lower connecting pieces 1, the arch bar grooves 12 are symmetrically arranged at the top ends of the upright post grooves 11, and the opening directions of the two arch bar grooves 12 are inclined upwards. The arch bar groove is used for supporting and supporting the arch bar. In this embodiment, the ends of the upright post groove 11 and the arch bar groove 12 are intersected at the same position, which is beneficial to ensuring that the upright post and the arch bar have the maximum supporting length and improving the supporting stability of the upright post and the arch bar.

Further, in the included angle area formed by the upright post groove 11 and the arch bar groove 12 and the included angle area formed by the two arch bar grooves 12, a plurality of bolts 3 are used for connecting and fixing the two lower connecting pieces 1. In order to ensure that the two lower connecting pieces 1 are stably connected, three included angle areas at the intersection positions of the upright post groove 11 and the arch bar groove 12 are fixedly connected by using bolts 3, so that the supporting stability of the upright post and the two arch bars is effectively ensured.

Further, the top ends of the two lower connecting pieces 1 are respectively provided with a supporting top plate 13, the supporting top plates 13 are perpendicular to the top ends of the lower connecting pieces 1, and the supporting top plates 13 on the two lower connecting pieces 1 respectively extend towards two sides and are integrally formed with the lower connecting pieces 1.

The upper connecting piece 2 comprises a base 21 and two supporting side walls 22, and the base 21 is connected and supported on the supporting top plate 13. Bolt holes are formed in the two supporting top plates 13, and bolt holes are also formed in corresponding positions of the base 21, so that the base 21 and the supporting top plates 13 are fixedly connected through bolts. The supporting side walls 22 on both sides are also provided with a plurality of mounting holes, and the mounting holes are connected with the side edges of the rain gutter through self-tapping screws or bolts and used for fixing the rain gutter.

Furthermore, side flanges 221 are respectively arranged on two sides of the supporting side wall 22 and are used for supporting the arch bars fixed in the limiting arch bar grooves 12. When the arch bar supporting device is used specifically, the two side turned edges 221 form a U-shaped groove, after the arch bar is supported in the arch bar groove 12, the arch bar just penetrates through the U-shaped groove formed by the two side turned edges 221, so that side support is provided for the arch bar, and the arch bar is effectively prevented from sliding.

Furthermore, two side edges of the base 21 are provided with downward turned edges 211, and the downward turned edges 211 are supported on the edge of the supporting top plate 13. When the upper connecting piece 2 is connected and fixed on the supporting top plate 13, in order to prevent the relative sliding between the upper connecting piece 2 and the lower connecting piece 1, the two side edges of the base 21 of the upper connecting piece 2 are provided with lower flanging 211 extending towards the lower end, and the lower flanging 211 is clamped at the two sides of the supporting top plate 13 to prevent the relative sliding between the lower connecting piece 1 and the upper connecting piece 2.

Further, in order to ensure that the bottom sides of the two supporting sidewalls 22 of the upper connecting member 2 are effectively attached to the arch bar, so that the arch bar passes through a U-shaped groove formed by the two side flanges 221 to provide lateral support for the arch bar, the inclination direction of the supporting sidewalls 22 is defined to be the same as the inclination direction of the arch bar groove 12 in this embodiment.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
