Description

Technical Field

[0001] This utility model relates to the field of rope fixing structure technology, specifically a simple seedbed rope fixing device that facilitates rope replacement. Background Technology

[0002] In modern agricultural planting, seedbeds are crucial facilities for cultivating seedlings, and ropes, as key components of the seedbed's fixing structure, play a vital role in supporting the seedbed netting and securing the plants. Because seedbeds are constantly exposed to moisture and sunlight, ropes are prone to wear and aging, and their strength and toughness decrease over time, seriously affecting the stability and safety of the seedbed. Furthermore, crops at different growth stages have different requirements for rope tightness and fixing methods; to ensure healthy seedling growth, ropes must be replaced promptly according to actual conditions.

[0003] Currently, most existing seedbed rope fixing devices use bolt fastening and clip connections. When replacing ropes, multiple bolts need to be disassembled or clips repeatedly adjusted using tools, which is cumbersome and time-consuming. Especially in large-scale planting scenarios, frequent rope replacements consume a lot of manpower and time, seriously affecting production efficiency. Utility Model Content

A top cover is threadedly connected to the top of the outer sleeve, and a mounting plate is fixedly connected to the side end of the top cover. A ratchet is fixedly connected to the top of the rope bolt, a rotating shaft is fixedly connected to the top surface of the ratchet, a square rod is fixedly connected to the top of the rotating shaft, a rotating handle is inserted into the outer surface of the square rod, a pin is rotatably connected inside the top cover, a pawl is threadedly connected to the bottom end of the pin, a lever is threadedly connected to the upper surface of the pawl, a pin is threadedly connected to the lower surface of the top cover, and an arc-shaped spring is sleeved on the outer surface of the pin.

[0013] Compared with the prior art, this utility model provides a simple seedbed rope fixing device that facilitates rope replacement, and has the following beneficial effects:

[0014] In terms of rope fixing, this utility model uses fixing nails to weave the ropes into a mesh to support the seedbed.

[0020] 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.

[0021] Please see Figures 1-4 A simple seedbed rope fixing device for easy rope replacement includes a rope bolt 1, a rectangular groove 2 through which the outer surface of the rope bolt 1 is opened, and an outer sleeve 3 is rotatably connected to the bottom of the rope bolt 1. A top cover 4 is threadedly connected to the top of the outer sleeve 3. An mounting plate 5 is fixedly connected to the side end of the top cover 4. A ratchet 6 is fixedly connected to the top of the rope bolt 1. A rotating shaft 7 is fixedly connected to the top surface of the ratchet 6. A square rod 8 is fixedly connected to the top of the rotating shaft 7. A rotating handle 9 is inserted into the outer surface of the square rod 8. A pin 10 is rotatably connected inside the top cover 4. A pawl 11 is threadedly connected to the bottom end of the pin 10. A lever 12 is threadedly connected to the upper surface of the pawl 11. A pin 13 is threadedly connected to the lower surface of the top cover 4. An arc-shaped spring piece 14 is sleeved on the outer surface of the pin 13.

[0022] Specifically, the outer surface of the outer sleeve 3 is provided with slots through which the seedbed ropes can pass, and the mounting plate 5 is fixedly connected to the side wall of the seedbed outer frame 15 by bolts.

[0023] Specifically, multiple fixing nails 16 are fixedly connected to the top edge of the seedbed outer frame 15, and the multiple fixing nails 16 are used to attach ropes 17.

[0024] The advantage is that by welding multiple fixing nails 16 onto the outer frame 15 of the seedbed, and by alternately looping ropes 17 around the outer surface of the fixing nails 16, the ropes 17 can be woven into a net to support the seedbed. When tightening the fixing ropes 17, one end of the rope 17 is passed through the slot on the outer surface of the outer sleeve 3, and then the other end of the rope 17 is passed through the rectangular slot 2. By rotating the handle 9 clockwise, the square rod 8 is rotated, which in turn drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the ratchet 6 and the rope bolt 1 to rotate, so that the rope bolt 1 can wind up the rope 17, thus tightening the rope 17. By setting the pawl 11 to limit the ratchet 6, and because the arc-shaped spring piece 14 abuts against the outer wall of the pawl 11, the ratchet 6 will not rotate in the opposite direction, thus keeping the rope 17 in a taut state.

[0025] Specifically, the ratchet 6 and the pawl 11 are mechanically engaged, and the outer surface of the pawl 11 is fitted with an arc-shaped spring piece 14.

[0026] Specifically, a knob 18 is fixedly connected to the top surface of the top cover 4, and a rotating shaft 7 is inserted through the center of the knob 18.

[0027] Specifically, an arc-shaped groove is provided through the top surface of the top cover 4, and a lever 12 is inserted into the arc-shaped groove. The bottom end of the lever 12 is threadedly connected to a pawl 11.

[0028] The advantage is that by fixing a knob 18 to the top surface of the top cover 4, the outer sleeve 3 and the top cover 4 can be easily separated by turning the knob 18. When the rope 17 needs to be replaced, the lever 12 is simply turned to cause the pawl 11 to shift. In this way, the pawl 11 can overcome the resistance of the arc-shaped spring 14 and no longer resist the outer surface of the ratchet 6. Then, by turning the handle 9 in the opposite direction, the rope bolt 1 can be turned in the opposite direction, thereby quickly releasing the rope 17. When the rope 17 becomes loose, it can quickly break free from the constraint of multiple fixing nails 16, achieving the purpose of quickly removing the rope 17 and making it possible to quickly replace the new rope 17.

[0029] In use, firstly, the mounting plate 5 is fixed to the side wall of the seedbed outer frame 15 with bolts. Multiple fixing nails 16 at the top edge of the seedbed outer frame 15 are used to alternately loop the rope 17 around its outer surface to weave a net to support the seedbed. Next, one end of the rope 17 is passed through the slot on the outer surface of the outer sleeve 3, and then through the rectangular slot 2 on the outer surface of the rope bolt 1. Then, the handle 9 is rotated clockwise, causing the square rod 8, the shaft 7, the ratchet 6, and the rope bolt 1 to rotate, thereby winding up the rope 17 and tightening it. At this time, the pawl 11, under the action of the arc-shaped spring piece 14, limits the ratchet 6, keeping the rope 17 taut. When the rope 17 needs to be replaced, the lever 12 is moved to shift the pawl 11, causing it to overcome the resistance of the arc-shaped spring piece 14 and no longer contact the ratchet 6. Then, the handle 9 is rotated in the opposite direction to rotate the rope bolt 1 in the opposite direction, releasing the rope 17 and freeing it from the constraint of the fixing nails 16, completing the removal process. After that, a new rope 17 can be replaced.
