Description

Technical Field

[0001] This utility model belongs to the field of greenhouse technology, specifically relating to a stable connection structure for greenhouse frame. Background Technology

[0002] The main function of a greenhouse is to provide a suitable growing environment for plants, ensuring that planting and cultivation can continue even during seasons unsuitable for open-field growth. Through its light transmission and heat preservation functions, a greenhouse can provide the necessary growing conditions for plants during cold seasons, increasing yields. It is widely used for the cultivation and seedling raising of warm-loving vegetables, flowers, and trees during cold seasons.

[0003] During greenhouse installation, the frame rods are fixed to pre-embedded parts in the ground, and then the side connecting rods are welded to the outside of the frame rods. This type of greenhouse is relatively inconvenient to disassemble. To solve this problem, Chinese patent document CN 221554108 U discloses an assembled greenhouse frame structure. By using a limiting plate set on the outside of the frame rods, and in conjunction with the side connecting rods, the side connecting rods are slidably connected to the outside of the limiting plate through through holes. At this time, the two ends of the pressure plate are inserted into the inside of the limiting groove, and the rotating rod is rotatably connected to the inside of the threaded groove through the round hole, ensuring the connection stability between the pressure plate and the limiting groove.

[0004] However, the above technical solution has the following drawbacks: 1. It requires many components such as side connecting rods, limiting plates, pressure plates, long plates, and baffles, which are difficult to process and manufacture due to the large number of parts; 2. Its main limiting structure is to limit the position by inserting the pressure plate into the limiting groove of the limiting plate. The limiting groove is a through groove structure, which greatly reduces the stability of the structure and results in insufficient overall stability; 3. The overall structure is complex and not conducive to quick assembly and disassembly. Utility Model Content

[0027] Specifically, the fixing mechanism includes a mounting groove 5 formed on the portion of the connector 3 that extends into the receiving cavity, and the connecting rod 2 also has a corresponding mounting groove 5. Fixing members 6 are installed in both mounting grooves 5. In this embodiment, the fixing member 6 can be selected from a variety of structures, not limited to the locking structure disclosed in this application. Conventional structures such as screw fixing of the mounting groove 5 can also be used.

[0028] Specifically, the mounting groove 5 of the connector 3 is provided with a larger diameter receiving groove 7, and the receiving groove 7 is provided with limiting grooves 8 on both sides of the top of the mounting groove 5. The top of the fixing member 6 is provided with a limiting protrusion 9 that is stuck in the limiting groove 8. In this embodiment, the limiting protrusion 9 enters the limiting groove 8 to limit and position the fixing member 6, and further positions the connector 3.

[0029] Specifically, one end of the fixing member 6 that extends into the receiving groove 7 is provided with a cylinder 10, and a strong spring 11 is fixedly installed inside the cylinder 10. The strong spring 11 is pressed between the fixing member 6 and the top of the receiving groove 7. In this embodiment, under the strong compression of the strong spring 11, the limiting protrusion 9 enters the limiting groove 8 for limitation, thereby locking the skeleton arch rod 1, connecting rod 2, and connecting member 3. During use, under the strong compression of the strong spring 11, the limiting protrusion 9 will not completely disengage from the limiting groove 8, thus ensuring stability.

[0030] Specifically, the top of the receiving groove 7 is provided with a positioning groove 12 corresponding to the strong spring 11, and the opening of the positioning groove 12 is an open structure; in this embodiment, the upper and lower ends of the strong spring 11 are located inside the cylinder 10 and the positioning groove 12 respectively, which is conducive to positioning during installation and the strong spring 11 is not easy to tilt or shift; the open structure is conducive to the spring entering.

[0031] Specifically, the mounting groove 5 has a vertical sliding groove 13 through its inner wall, and the sliding groove is corresponding to the limiting protrusion 9; in this embodiment, the sliding groove 13 is provided to provide an entry and exit channel for the limiting protrusion 9.

[0032] Specifically, the bottom end of the fastener 6 is provided with a cross-shaped groove 14; in this embodiment, the fastener 6 is rotated through the cross-shaped groove 14 by an external screwdriver.

[0033] Specifically, the fixing mechanism is installed on the upper, lower or side part of the connecting rod 2. In this embodiment, the installation position of the fixing mechanism is rotated according to the actual situation. For example, when the connecting rod is low and close to the ground, the fixing mechanism is set on the top to facilitate operation. When the connecting rod is at the top, the fixing mechanism can be set on both sides.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] Working principle: During connection, insert connector 3 into the connection point of frame arch rod 1 and connecting rod 2. Limiting plate 4 limits connector 3 on one side. Install connecting rod 2 at the other end of connector 3. After it is in place, use an external screwdriver to install fixing part 6 along mounting groove 5 through cross-shaped groove 14. Fixing part 6 is a cylindrical column. When fixing part 6 enters mounting groove 5, limiting protrusion 9 slides upward along sliding groove 13 until the top of fixing part 6 enters receiving groove 7. Strong spring 11 will enter positioning groove 12. Then, forcefully squeeze strong spring 11 to make fixing part 6 continue to move upward, so that fixing part 6 is fully inserted into receiving groove 7. Then, rotate fixing part 6 ninety degrees with screwdriver. Position the limiting protrusion 9 directly above the limiting groove 8, then loosen the fixing piece 6. Under the strong compression of the strong spring 11, the limiting protrusion 9 enters the limiting groove 8 for positioning, thus locking the frame arch rod 1, connecting rod 2, and connecting piece 3. During use, under the strong compression of the strong spring 11, the limiting protrusion 9 will not completely detach from the limiting groove 8, thus ensuring stability. When disassembly is required, follow the same principle but operate in reverse order of installation. First, insert a screwdriver into the cross-shaped groove 14 to lift the fixing piece 6, causing the limiting protrusion 9 to completely detach from the limiting groove 8. Then, rotate it 90 degrees so that the limiting protrusion 9 aligns with the sliding groove 13. Finally, remove the fixing piece 6 to achieve complete disassembly.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
