Description

Technical Field

[0001] The utility model relates to the technical field of application of engineering construction accessories, in particular to a fastener for high-stability greenhouse construction. Background Art

[0002] Greenhouses are facilities that can transmit light and keep heat. They are used to cultivate plants. In seasons that are not suitable for plant growth, they can provide a greenhouse growth period and increase yields. They are mostly used for cultivating or raising seedlings of warmth-loving vegetables, flowers, trees and other plants in low temperature seasons. During the construction of greenhouses, a large number of fasteners will be used to fix and install beams, roofs and other structures to ensure the stability of the entire greenhouse. Fasteners are the most widely used mechanical basic parts. They are easy and quick to use. They are usually used in conjunction with nuts to connect and tighten.

[0003] However, in the actual use of the above equipment, since the greenhouse needs to have high insulation efficiency, there is a large difference in temperature and humidity inside and outside the greenhouse. At this time, water droplets are easily formed at the top of the beam, and these formed water droplets will also gather to the bottom of the bolts of the fasteners due to the tip effect. When more water droplets gather, larger water droplets will be formed. Eventually, these water droplets will fall downward under the action of gravity, which will have adverse effects whether they drip on the staff or the crops. In view of this, we proposed a fastener for high-stability greenhouse construction. Summary of the invention

[0004] The purpose of the utility model is to provide a fastener for greenhouse construction with high stability, so as to solve the problems raised in the above-mentioned background technology.

[0008] The threaded barrel is fixedly mounted on the inner bottom surface of the water collecting box. When the threaded barrel moves, it can drive the water collecting box to move synchronously. A limited position cavity is arranged at the inner bottom end of the threaded barrel.

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a fastener for high-stability greenhouse construction, comprising a hexagonal head 1, a screw 2 is fixedly installed on the upper surface of the hexagonal head 1, a nut 3 is threadedly connected to the upper end of the screw 2, and an anti-drip component is arranged below the hexagonal head 1.

[0023] The anti-drip assembly includes: a conical base 401, a water collecting box 406 and a threaded cylinder 408. The conical base 401 is fixedly installed on the bottom surface of the hexagonal head 1. A connecting rod 402 is fixedly installed on the bottom surface of the conical base 401. The top size of the connecting rod 402 is the same as the bottom size of the conical base 401. A rhombus 403 is fixedly installed on the outside of the connecting rod 402. The front cross-sectional surface of the rhombus 403 is a rhombus structure, which is composed of two cones arranged in a mirror structure. When the fastener is installed on the beam frame of the greenhouse for fixing and stabilization, if the temperature and humidity difference between the inside and outside of the greenhouse is large, water droplets will easily form at the beam frame, and these formed water droplets will also gather to the hexagonal due to the tip effect. The bottom end of the corner head 1 will form larger water droplets when more water gathers. At this time, these water droplets will continue to slide downward along the bottom inclined surface of the conical base 401 to the outside of the connecting rod 402. When sliding to the upper surface of the rhombus 403, it will slide along the upper inclined surface of the rhombus 403 to the outside of the rhombus 403. When the fastener is disassembled and reused to drain the accumulated water inside the water collecting box 406, the fastener is inverted. At this time, the accumulated water will slide out along the bottom inclined surface of the rhombus 403. The water collecting box 406 and the connecting rod 402 can use heat-insulating materials to avoid excessive water collection in the water collecting box 406, which will cause water droplets to form at the bottom of the water collecting box 406.

[0024] The outer bottom end of the connecting rod 402 is fixedly installed with an external thread 404, and the bottom end of the connecting rod 402 is fixedly installed with a limit block 405. The water collecting box 406 is arranged below the connecting rod 402. The internal size of the water collecting box 406 is adapted to the size of the rhombus 403. The inner upper end of the water collecting box 406 is provided with a chamfer 407. When the water drops slide down along the upper inclined surface of the rhombus 403 to the outside, they will enter the interior of the water collecting box 406 for collection. If the water drops onto the upper edge of the water collecting box 406, it will slide along the inclined surface of the chamfer 407 toward the inside of the water collecting box 406, avoiding accumulation at the upper edge of the water collecting box 406 and causing it to slide toward the outside of the water collecting box 406. When the water droplets enter the water collecting box 406 for collection, it can avoid forming larger water droplets at the bottom of the hexagonal head 1 and dripping onto the workers working inside the greenhouse, or dripping onto the crops planted inside the greenhouse that require strict control of water volume and affect the planting effect.

[0025] The threaded barrel 408 is fixedly mounted on the inner bottom surface of the water collecting box 406. The size of the external thread 404 matches the inner size of the threaded barrel 408. The external thread 404 is connected to the inner thread of the threaded barrel 408. A limiting cavity 409 is provided at the inner bottom of the threaded barrel 408. The limiting block 405 is located inside the limiting cavity 409. The limiting cavity 409 and the limiting block 405 can limit the bottom end of the connecting rod 402 to prevent it from being separated from the inner part of the threaded barrel 408, thereby preventing the water collecting box 406 from being damaged. 6 Excessive rotation may cause the bottom end of the connecting rod 402 to fall off and affect the use. When the fastener needs to be disassembled, the water collecting box 406 can be rotated, and the water collecting box 406 can be driven to move upward through the cooperation of the threaded barrel 408 and the external thread 404, so that the diamond body 403 enters the interior of the water collecting box 406. At this time, the diamond body 403 can seal the interior of the water collecting box 406 to prevent the collected water droplets from leaking from the inside of the water collecting box 406 during the disassembly of the fastener and splashing on the staff.

[0026] The outer side of the water collecting box 406 is provided with anti-slip grooves 501, and the anti-slip grooves 501 can increase the friction between the water collecting box 406 and the palm of the staff, thereby preventing the water collecting box 406 from slipping during rotation. A rubber ring 502 is fixedly installed on the upper end of the interior of the water collecting box 406, and a drainage chute 503 is provided on the upper end of the rubber ring 502. The upper end of the rubber ring 502 and the bottom end of the chamfer 407 are located at the same horizontal plane. When the rhombus 403 enters the interior of the water collecting box 406 for sealing, the rubber ring 502 can seal the gap between the rhombus 403 and the inner wall of the water collecting box 406, further preventing water from leaking from the interior of the water collecting box 406. The drainage chute 503 can make water droplets slide along the inclined surface of the drainage chute 503 toward the inside of the water collecting box 406 when dripping onto the rubber ring 502, avoiding gathering above the rubber ring 502.

[0027] In the utility model, when in use, when there is a large difference in temperature and humidity between the inside and outside of the greenhouse, more water vapor will gather on the beams of the greenhouse. At this time, there is a tip effect, and water droplets may form at the bottom of the hexagonal head 1 of the fastener. At this time, these water droplets will flow to the connecting rod 402 along the guidance of the bottom inclined surface of the conical base 401, and when flowing to the top of the rhombus 403, they will slide outward along the inclined surface of the rhombus 403, and finally enter the interior of the water collecting box 406 along the inclined surface of the chamfer 407 for collection, thereby avoiding the formation of larger water droplets at the bottom of the hexagonal head 1, causing them to drip downward onto crops or workers, causing adverse effects. When the fastener needs to be disassembled for maintenance, the water collecting box 406 can be rotated to drive the water collecting box 406 to move upward, so that the rhombus 403 enters the interior of the water collecting box 406 for sealing, thereby avoiding leakage of accumulated water inside the water collecting box 406 during the disassembly process, causing it to drip onto the workers.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
