Description

Technical Field

[0001] The utility model relates to the technical field of sunshade nets, in particular to a new type of windproof and dustproof sunshade net. Background Art

[0002] With the continuous expansion of the scale of greenhouse construction and the gradual improvement of internal facilities, the production function of greenhouses has become more and more important. The sunshade net is a very important supporting product for greenhouses. The sunshade net is a new type of special protective covering material for agriculture, fishery, animal husbandry, windbreak, soil covering, etc. It plays a role in blocking light, rain, moisturizing and cooling after covering in summer.

[0003] Existing sunshade nets generally use a reduction motor and a rotating rod to drive a small gear to rotate, and use the small gear, large gear and cross bar to drive the winding wheel to rotate, so as to automatically reel in the sunshade net body. Farmers do not need to reel it in manually, which saves time and effort, reduces farmers' workload and reduces labor costs.

[0004] However, during actual use of the above-mentioned equipment, when the net is automatically rolled up or unfolded, the sunshade net has strong toughness and ductility, and the net may fall from the slide grooves on both sides of the fixed frame, causing the net to swing significantly when blown by the wind, affecting the service life of the sunshade net. At the same time, due to the long net body, it is impossible to easily reinsert the edge of the net into the slide groove, which will cause friction between the net body and the fixed frame when rolling or unfolding, and will also affect the service life of the sunshade net. In view of this, we propose a new wind and dustproof sunshade net. Summary of the invention

[0005] The utility model aims to provide a new windproof and dustproof sunshade net to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new windproof and dustproof sunshade net, comprising a fixed frame, the inner wall surfaces of the front and rear sides of the fixed frame are provided with limit grooves, a reel is fixedly installed at the right end of the bottom surface of the fixed frame, a net body is arranged inside the reel, and a limit assembly is arranged inside the limit groove, and the limit assembly comprises:

[0011] The thin iron sheet is fixedly mounted on the front and rear ends of the mesh body, and can drive the thin iron sheet to move synchronously when the mesh body moves.

[0012] Preferably, the two air delivery ends at the bottom and side of the air pump respectively penetrate the upper and lower ends of the fixing frame and the installation frame and are fixedly connected to the outer walls of the airbag on the upper and lower sides of the limiting groove, so that the airbag can be inflated and deflated when the air pump is started.

[0013] Preferably, the magnet roller is located inside the through hole, so as to avoid the limiting plate from hindering the contact between the magnet roller and the mesh body, and the outer wall of the magnet roller fits with the outer wall of the thin iron sheet.

[0016] Preferably, a guide fillet is provided on one side of the through hole close to the center of the fixing frame, and chamfers are provided on both the front and rear ends of the limiting rod.

[0017] Compared with the prior art, the utility model provides a new windproof and dustproof sunshade net, which has the following beneficial effects:

[0018] 1. The new windproof and dustproof sunshade net can initially limit the unfolding of the net body through the cooperation of the set limit rod and the installation frame, thereby improving the stability of the net body when unfolded, and through the cooperation of the set grooves, rotating shafts, magnet rollers, limit plates and through holes, the front and rear ends of the net body can be limited during the unfolding of the net body to prevent it from escaping from the inside of the limit groove and causing the edge of the net body to fall off, affecting the stability of the net body after unfolding, and at the same time, it can prevent the limit rod from being inserted into the inside of the groove and causing obstruction of the unfolding or winding of the net body. Through the cooperation of the set airbags and air pumps, the edge of the net body can be clamped and limited after the net body is fully unfolded, thereby further improving the stability of the net body and preventing the net body from swinging greatly due to wind after it is fully unfolded, thereby affecting the service life of the sunshade net.

[0019] 2. This new windproof and dustproof sunshade net has a set guide fillet to prevent the limit rod from being slightly offset during movement, causing the through hole to hinder the movement of the limit rod. At the same time, the chamfer can reduce the friction force on the limit rod when it moves, thereby improving the smoothness of the net when it is unfolded or rolled up.

DETAILED DESCRIPTION

[0025] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a new type of windproof and dustproof sunshade net, including a fixed frame 1, the inner wall surfaces on the front and rear sides of the fixed frame 1 are provided with limiting grooves 2, a reel is provided at the bottom front end of the fixed frame 1, a connecting wire is provided inside the reel, the right end of the connecting wire is fixedly connected to the left end of the limiting rod 501, a winder 3 is fixedly installed at the right end of the bottom surface of the fixed frame 1, a net body 4 is provided inside the winder 3, the outer walls at the front and rear ends of the net body 4 are in contact with the inner walls of the limiting grooves 2 on the front and rear sides of the fixed frame 1, when the winder 3 is released, the winder starts synchronously, and the net body 4 can be unfolded, and the net body 4 can also be rolled up. This is the existing technical means in the field and will not be elaborated here. A limiting component is provided inside the limiting groove 2.

[0026] The limiting assembly includes: a limiting rod 501, an air pump 502, a mounting frame 503, a groove 505 and a thin iron sheet 510. The limiting rod 501 is fixedly installed at the left end of the net body 4. The limiting rod 501 can enhance the strength of the left end of the net body 4 to prevent the left end from falling when the net body 4 moves to the left end for unfolding, thereby affecting the complete unfolding of the net body 4. The air pump 502 is fixedly installed at the top of the fixed frame 1. There are two mounting frames 503. The two mounting frames 503 are respectively fixedly installed at the upper and lower ends of the inside of the limiting groove 2. The outer wall of the mounting frame 503 fits the outer wall of the limiting rod 501. The inside of the mounting frame 503 An airbag 504 is fixedly installed on the surface of one side away from the limiting groove 2, and the outer wall of the airbag 504 fits with the inner wall of the fixing frame 1. The two air delivery ends at the bottom and side of the air pump 502 respectively penetrate the upper and lower ends of the fixing frame 1 and the installation frame 503 and are fixedly connected with the outer walls of the airbag 504 on the upper and lower sides of the limiting groove 2. When the net body 4 is fully unfolded, the air pump 502 can be started to inflate the inside of the airbag 504, so that the airbag 504 expands and clamps the edge of the net body 4, so that the net body 4 can be more stable after unfolding, avoiding serious fluttering of the net body 4 when the wind blows, thereby affecting the service life of the net body 4.

[0027] The groove 505 is opened on one side surface of the limiting groove 2 away from the inner center of the fixed frame 1, and a rotating shaft 506 is fixedly installed inside the groove 505. The outer side of the rotating shaft 506 is rotatably connected to a magnet roller 507. A limiting plate 508 is fixedly installed at one end of the groove 505 close to the inner center of the fixed frame 1. The limiting plate 508 can limit the movement of the limiting rod 501, thereby preventing the limiting rod 501 from being offset and inserted into the inner part of the groove 505 during movement, thereby hindering the unfolding or winding of the net body 4.

[0028] A through hole 509 is provided on one side surface of the limiting plate 508 near the center of the limiting groove 2, and a thin iron sheet 510 is fixedly installed at the front and rear ends of the mesh body 4. The magnet roller 507 is located inside the through hole 509, and the outer wall of the magnet roller 507 fits with the outer wall of the thin iron sheet 510. When the mesh body 4 is unfolded, the edge will fit with the magnet roller 507 and move. During this process, the magnet roller 507 will magnetically attract the thin iron sheet 510. When the mesh body 4 moves, the magnetic attraction between the magnet roller 507 and the thin iron sheet 510 will drive the magnet roller 507 to rotate, thereby avoiding obstruction to the movement of the mesh body 4. At the same time, the edge of the mesh body 4 can be limited to avoid escaping from the limiting groove 2, causing the edge of the mesh body 4 to fall off, affecting the stability of the mesh body 4 after unfolding.

[0029] A guide fillet 601 is provided on one side of the through hole 509 near the center of the fixed frame 1. When the limit rod 501 is slightly offset during movement, it can be moved and corrected along the arc surface of the guide fillet 601 to avoid being stuck inside the through hole 509. Chamfers 602 are provided at the front and rear ends of the limit rod 501. The chamfers 602 can reduce the contact area between the limit rod 501 and the limit plate 508, thereby reducing the friction when the net body 4 is unfolded, making the unfolding of the net body 4 smoother.

[0030] In the utility model, during use, when the net body 4 is unfolded, the net body 4 can be initially limited by the cooperation of the set limit rod 501 and the installation frame 503, and the limit plate 508 can prevent the limit rod 501 from being offset and entering the groove 505 to cause jamming. At the same time, during the unfolding of the net body 4, the magnet roller 507 can limit the thin iron sheet 510 to prevent the front and rear ends of the net body 4 from being separated from the inside of the limit groove 2, thereby affecting the stability of the net body 4 after it is fully unfolded. During the unfolding process, the magnet roller 507 can rotate relative to the net body 4 to avoid obstruction to the unfolding of the net body 4. After full unfolding, the air pump 502 can be started to inflate the inside of the airbag 504, so that the airbag 504 expands to limit and clamp the front and rear ends of the net body 4, further preventing the front and rear ends of the net body 4 from being separated from the inside of the limit groove 2.

[0031] 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.
