The connecting assembly includes a metal clamp that engages with the crossbeam arch. The end of the metal clamp that engages with the crossbeam arch has several through holes. Bolts are inserted into the interior of each through hole, and the threaded ends of the bolts are screwed into the crossbeam arch. A U-shaped groove is provided at the end of the metal clamp that is furthest from the crossbeam arch. A support rod and a limiting block are intersected inside the U-shaped groove. The connecting assembly and the limiting block facilitate the movable connection between the greenhouse crossbeam arch and the support rod, shortening the installation and disassembly time of the greenhouse crossbeam arch and improving the installation and disassembly efficiency.

[0003] In the aforementioned patent, some of the greenhouses are prone to collapse during blizzards due to their poor wind and snow resistance, resulting in damage to crops and serious economic losses. The unstable structure also shortens the lifespan of the greenhouses, affecting the continuity and stability of agricultural production. Utility Model Content

[0004] The purpose of this utility model is to provide a wind and snow resistant enhanced greenhouse arch frame connection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind and snow resistant greenhouse arch frame connection device, comprising a first arch beam mechanism and a second arch beam mechanism, wherein a connection mechanism is provided between the first arch beam mechanism and the second arch beam mechanism, the connection mechanism comprising a fixing block, wherein arc-shaped short plates are fixedly connected to the upper ends of the fixing block respectively, and slots are respectively provided at the two ends of the fixing block, wherein the slots are located below the arc-shaped short plates, an arc-shaped long plate is fixedly connected to the lower end of the fixing block, and a connection component is provided below the fixing block.

[0006] Furthermore, two locking slots are provided on the upper part of the arc-shaped plate, and the two locking slots are symmetrically arranged with the fixing block as the axis.

[0007] Furthermore, the connecting assembly includes an inverted U-shaped plate fixedly connected to the lower end of the arc-shaped long plate, and two connecting rods are provided at the lower end of the inverted U-shaped plate.

[0008] Furthermore, the inverted U-shaped plate has two through holes for bolt insertion, and the two ends of the connecting rod have insertion holes corresponding to the bolts.

[0009] Furthermore, the first arch beam mechanism includes an arc-shaped arch beam, a connecting short plate is fixedly installed on the inner side of the arc-shaped arch beam near the center, the connecting short plate has through holes corresponding to bolts, the upper end of the arc-shaped arch beam has a recessed groove, a plug rod is fixedly connected to one end of the arc-shaped arch beam near the connecting mechanism, and a U-shaped rod is located on the lower inner side of the arc-shaped arch beam, the position of the U-shaped rod corresponding to the arc-shaped long plate.

[0010] Furthermore, a sliding groove is provided on the lower inner side of the arc-shaped arch beam, and a sliding block is slidably disposed inside the sliding groove. A connecting plate is fixedly connected to one side of the sliding block, and a sliding cavity for the connecting plate to slide is provided on one side of the sliding groove. A spring is fixedly connected to the upper end of the connecting plate, and the other end of the spring is fixedly connected to the upper part of the sliding cavity.

[0011] Furthermore, the sliding block is positioned below the recessed groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the wind and snow resistant enhanced greenhouse arch frame connection device is reasonable and has the following advantages:

[0013] (1) The first arch beam mechanism and the second arch beam mechanism are respectively set on both sides of the fixed block. The connecting component is set below the fixed block. The connecting device significantly improves the wind and snow resistance of the greenhouse arch frame through multiple locking and reinforcement mechanisms. First, the combination of the insertion rod and the slot and the fitting of the arc short plate and the recessed groove realizes the initial positioning and connection of the arch beam mechanism, forming a stable basic structure. When the arc long plate slides into the U-shaped rod as the insertion rod is inserted, the inclined surface of its lower surface will trigger the automatic locking function of the sliding block. The sliding block is accurately locked into the locking groove under the action of the spring, forming a mechanical interlock, which effectively prevents the lateral displacement of the arch beam under wind load or snow load. This self-locking design does not require manual intervention, which improves the installation efficiency and ensures the reliability of the connection.

[0014] (2) The connecting rod of the connecting component and the arc-shaped arch beam form a triangular reinforced frame. The arc-shaped arch beam and the connecting rod are rigidly connected by bolts. This design disperses the local stress to the entire arch frame system, greatly reducing the risk of stress concentration at a single point. Especially in blizzard weather, the connecting rod can effectively resist the bending deformation of the arch beam, prevent the arch frame from collapsing due to snow overload or strong wind impact, significantly extend the service life of the greenhouse, and ensure the safe production of crops. The arch frame is decomposed into three standardized components: the first arch beam mechanism, the second arch beam mechanism, and the connecting mechanism, which greatly simplifies the construction process. During installation, it is only necessary to align the insert rod with the slot and insert it. The automatic engagement of the sliding block and the locking groove can complete the main connection. It takes less time than traditional welding or bolt splicing. The connecting rod is fixed with the bolt through the pre-made through hole, which can be operated without professional tools, reducing the construction threshold. In addition, the sliding fit design of the arc-shaped long plate and the U-shaped rod allows a certain degree of installation error, which improves the fault tolerance rate and is particularly suitable for rapid outdoor construction scenarios.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A wind and snow resistant greenhouse arch frame connection device includes a first arch beam mechanism 1 and a second arch beam mechanism 2. A connection mechanism 3 is provided between the first arch beam mechanism 1 and the second arch beam mechanism 2. The connection mechanism 3 includes a fixing block 31. Arc-shaped short plates 32 are fixedly connected to the upper ends of the fixing block 31. Slots 33 are opened at both ends of the fixing block 31. The slots 33 are located below the arc-shaped short plates 32. An arc-shaped long plate 34 is fixedly connected to the lower end of the fixing block 31. A connection component 35 is provided below the fixing block 31.

[0025] Two locking slots 341 are provided on the upper part of the arc-shaped long plate 34, and the two locking slots 341 are symmetrically arranged with the fixing block 31 as the axis.

[0026] The connecting component 35 includes an inverted U-shaped plate 351 fixedly connected to the lower end of the arc-shaped long plate 34, and two connecting rods 352 are provided at the lower end of the inverted U-shaped plate 351.

[0027] The inverted U-shaped plate 351 has two through holes for bolt insertion, and the connecting rod 352 has corresponding insertion holes at both ends. The bolts fix one end of the connecting rod 352 to the inverted U-shaped plate 351 through the through holes on the inverted U-shaped plate 351 and the connecting rod 352.

[0028] The first arch beam mechanism 1 includes an arc-shaped arch beam 11. A connecting short plate 12 is fixedly installed on the inner side of the arc-shaped arch beam 11 near the center. The other end of the connecting long rod 352 is set on the connecting short plate 12. The connecting long rod 352 is fixed to the connecting short plate 12 by bolts passing through the through holes on the connecting short plate 12. The connecting short plate 12 has through holes corresponding to the bolts. A recessed groove 13 is opened at the upper end of the arc-shaped arch beam 11. A plug rod 15 is fixedly connected to one end of the arc-shaped arch beam 11 near the connecting mechanism 3. The plug rod 15 matches the slot 33. There is a U-shaped rod 14 on the lower inner side of the arc-shaped arch beam 11. The position of the U-shaped rod 14 corresponds to the arc-shaped long plate 34.

[0029] A sliding groove 16 is provided on the lower inner side of the arched beam 11. A sliding block 17 is slidably arranged inside the sliding groove 16. An inclined surface is provided on one side of the lower part of the sliding block 17. A connecting plate 18 is fixedly connected to one side of the sliding block 17. A sliding cavity for the connecting plate 18 to slide is provided on one side of the sliding groove 16. A spring 19 is fixedly connected to the upper end of the connecting plate 18. The other end of the spring 19 is fixedly connected to the upper part of the sliding cavity.

[0030] The sliding block 17 is located below the recessed groove 13.

[0031] Working principle: In use, the insertion rod 15 is inserted into the slot 33. When the insertion rod 15 is inserted into the slot 33, the arc-shaped short plate 32 slides into the recessed groove 13, and the arc-shaped long plate 34 slides against the inner wall of the arc-shaped arch beam 11. The arc-shaped long plate 34 slides into the U-shaped rod 14. When the arc-shaped long plate 34 slides against the lower surface of the arc-shaped arch beam 11, the arc-shaped long plate 34 presses against the inclined surface below the sliding block 17, and the sliding block 17 is pressed into the sliding groove 16. When the insertion rod 15 is fully inserted into the slot 33, the locking groove 341 is located below the sliding block 17. The spring 19 pushes the connecting plate 18 to move downward. The connecting plate 18 drives the sliding block 17 to move out of the sliding groove 16. The sliding block 17 is inserted into the locking groove 341, locking the arc-shaped long plate 34, so that the fixing block 31 cannot be attached to the arc-shaped arch beam 11. After beam 11 is separated, the same operating steps are followed to install the second arch beam mechanism 2 on the other side of the fixing block 31. At this time, the fixing block 31, the first arch beam mechanism 1 and the second arch beam mechanism 2 form a complete greenhouse arch frame. In the event of strong winds and heavy snow, one end of the connecting rod 352 is inserted into the inverted U-shaped plate 351. The connecting rod 352 is fixed in the inverted U-shaped plate 351 by passing a bolt through the through hole on the connecting rod 352 and the inverted U-shaped plate 351. The through hole at the other end of the connecting rod 352 is aligned with the through hole on the connecting short plate 12. The other end of the connecting rod 352 is fixed to the connecting short plate 12 by bolts. This increases the strength of the arch beam 11, so that the arch beam 11 will not collapse due to insufficient support in the event of strong winds and heavy snow, thus affecting greenhouse planting.
