[0002] Screen door is a common mosquito-proof device, which is installed on the door frame to prevent mosquitoes from entering the room. It is a mosquito-proof device with good mosquito-proof effect and beautiful appearance, and is deeply loved by consumers. The existing screen door is generally made by first cutting the raw gauze into two gauze sheets, then sewing the magnetic material to the gauze sheets in the form of hemming, sewing the two gauze sheets into a screen door, sewing the fur surface of the Velcro on the screen door, and using the Velcro to stick the screen door to the door frame during installation.

[0003] After an ordinary screen door has been used for a period of time, the weight of the magnetic material and the screen door itself will constantly pull down the load-bearing part of the Velcro on the top of the screen door, causing the Velcro to slowly tear and separate, eventually causing the top of the screen door to loosen, making it difficult for the screen door to close automatically, thereby affecting the use of the screen door and reducing its service life; the service life of existing screen doors is not ideal.

[0016] Preferably, the middle edge reinforcement structure is set as a fourth fixed plate, and the fourth fixed plate includes two L-plates. The L-plate is sewn between the reinforcing edge cloth and the fleece surface, and an L-plate is sewn on each of the two gauze pieces.

[0021] Preferably, a fixing column is further provided above the fixing frame, which can block the transverse piece, and when the transverse piece rotates along its connection with the first middle piece to a predetermined angle and contacts the fixing column, only one corner of the square piece is stuck in the fixing frame.

[0022] After adopting the above technical solution, the beneficial effects of the utility model are:

[0023] 1. By setting the first fixed plate and using the first horizontal plate to hang the reinforced edge cloth at the top of the middle edge, when the screen door tends to fall due to gravity, the middle part falls first, and the first horizontal plate hangs the reinforced edge cloth at the top of the middle edge. The gravity of the gauze sheet and the magnetic material is shared by the Velcro and the first horizontal plate, thereby avoiding the situation where only the Velcro bears the gravity, and avoiding the hook surface and the fleece surface from slowly separating. Before the first horizontal plate breaks and does not separate, the middle edge of the gauze sheet will not fall, so that the firmness of the bonding between the gauze sheet and the door frame is greatly increased, the service life is longer, and the user experience is better; the contact area between the first bottom plate and the door frame is larger, compared with only one layer of hook surface glued to the door frame, the first bottom plate is more firmly bonded to the door frame, reducing the possibility of degumming and falling.

[0024] Second, by setting self-tapping screws and fixing holes, while using the first horizontal plate to hang the top of the middle side, you can choose to use self-tapping screws to penetrate the reinforcing edge cloth and gauze to fix the reinforcing edge cloth and the first horizontal plate, further increasing the supporting effect of the first horizontal plate. The self-tapping screws only penetrate the reinforcing edge cloth and gauze. Compared with the nail plate commonly used in the prior art, the screws need to penetrate the hook surface, the rough surface, the reinforcing edge cloth and the gauze, while the self-tapping screws only penetrate the reinforcing edge cloth and gauze that are relatively easy to penetrate, which is more convenient for installation.

[0025] 3. When weaving the yarn, a certain number of elastic threads are added between the weft monofilaments. When the density of the elastic threads increases, the light transmittance of the yarn will decrease. The density of the elastic threads is increased locally to reduce the local light transmittance of the yarn, so that the yarn can partially achieve the effect of a privacy curtain. Compared with the prior art, the warp monofilaments and the weft monofilaments have the same density. After the weaving of the flat net is completed, patterns are sewn on the flat net with thread, or cloth pieces are sewn. The production method of using elastic threads is simpler and the integrity of the yarn is better. The density of the elastic threads can be gradually changed to achieve a gradual effect, and different light transmittances can be customized according to usage requirements, thereby providing a better user experience.

[0026] 4. Use the weft monofilament to limit the elastic wire. After adding the elastic wire, the elasticity of the elastic wire is different from that of the weft monofilament. Therefore, when subjected to pulling force in the horizontal direction, the elastic wire can withstand the pulling force, thereby greatly reducing the situation of wire slippage; due to the large number of elastic wires, in the vertical direction, it can also increase stability to a certain extent and reduce the possibility of wire slippage; the screen door is generally pushed open during the opening and closing process, and the tensile resistance of the yarn in the horizontal and vertical directions is increased, thereby making the yarn more resistant to deformation and having a longer service life.

[0027] 5. By setting fixing strips and fixing grooves, the fixing strips are opened with fixing grooves in advance, and scale lines are set on the fixing strips to facilitate the operation of production personnel, and the fixing grooves are opened uniformly in advance, and the spacing between the fixing grooves is the same. Compared with using non-woven fabrics to fix magnetic materials, when the screen door is closed, there are two layers of non-woven fabrics and two layers of reinforced edge cloths between the corresponding group of magnetic materials. When the fixing strips are used to fix the magnetic materials, there are only two layers of reinforced edge cloths between the corresponding group of magnetic materials. The magnetic loss of the magnetic material is reduced, and the relative magnetic force is increased, which makes it easier to close the screen door and increases the user experience.

[0028] Sixth, by clamping the square piece on the horizontal piece in the fixed frame, the bottoms of the two gauze pieces are connected together, and the bottoms cannot be opened outwards. When the pet pushes the horizontal piece upward, the horizontal piece rotates along the pin for a certain distance, and the top of the horizontal piece contacts the fixed column to prevent the horizontal piece from continuing to rotate. At this time, one corner of the square piece is still in the fixed frame, so the square piece and the fixed frame will not be separated, thereby preventing the screen door from opening from the bottom; when the user needs to open the screen door, he only needs to lift the gauze piece on one side of the first middle piece upward, and the horizontal piece is kept in a horizontal state under the action of the stopper. Before the horizontal piece contacts the bottom of the fixed column, the square piece and the fixed frame can be separated, thereby opening the screen door, which is simple and convenient to operate; and the reinforced edge cloth is made of harder polyester material in the vertical direction, which is also convenient for the user to pull one of the gauze pieces. The two gauze pieces are dislocated in the vertical direction to a certain extent, and the fixed piece itself also strengthens the anti-deformation ability of the bottom of the gauze piece, thereby facilitating the square piece to be moved out of the fixed frame; the fixed piece has a certain weight, and the weight of the first middle piece and the second middle piece is greater than the weight of the remaining fixed pieces, which can enhance the natural closing ability of the screen door.

DETAILED DESCRIPTION

[0046] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples.

The installation method, connection method or setting method of all the above-mentioned components are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0048] The utility model is a durable screen door with a reinforced structure. Unless otherwise specified, the directional words contained in the terms such as "up, down, left, right, front, back, inside, outside, vertical and horizontal" only represent the directions of the terms in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms. At the same time, the number series nouns such as "first", "second" and "third" do not represent specific quantities and sequences, but are merely used to distinguish names. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or equipment that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or equipment.

[0049] Embodiment 1:

[0050] like Figure 1-Figure 6 As shown:

[0051] The middle edge reinforcement structure is set as a first fixed plate, which includes a first bottom plate 6 and a first cross plate 7. The first bottom plate 6 and the first cross plate 7 are fixedly connected by a connecting plate 8. The first bottom plate 6 is set between the hook surface 4 and the door frame 3, and one end of the first cross plate 7 can hang the top of the middle part of the two gauze sheets 1; during installation, first use double-sided tape to fix the first bottom plate 6 to a predetermined position on the door frame 3, and then stick the hook surface 4 with adhesive backing on the door frame 3, the hook surface 4 covers the first bottom plate 6, and the fur surface 5 of the edge of the gauze sheet 1 is stuck on the corresponding hook surface 4, the first cross plate 7 is inserted between the two gauze sheets 1, and the two sides of the two gauze sheets 1 close to each other are called middle edges. After using the first cross plate 7 to hang the reinforced edge cloth 2 of the middle edge, the screen door can be used normally. Under the influence of gravity, when the screen door has a tendency to fall, the middle parts of the two gauze sheets 1 are provided with magnetic materials 22, so the middle part will fall first. At this time, the first cross plate 7 hangs the reinforced edge cloth 2 at the top of the middle edge. When sewing the reinforced edge cloth 2 and the gauze piece 1, a reinforcement line is provided at the top of the middle edge of the gauze piece 1, so that the top of the middle edge of the gauze piece 1 is not easy to break. After the first cross plate 7 hangs the reinforced edge cloth 2 at the top of the middle edge, the gravity of the gauze piece 1 and the magnetic material 22 is shared by the Velcro and the first cross plate 7, thereby avoiding the situation where only the Velcro bears the gravity, and avoiding the hook surface 4 and the fur surface 5 to slowly separate. Before the first cross plate 7 breaks and does not separate, the middle edge of the gauze piece 1 will not fall, so that the firmness of the gauze piece 1 and the door frame 3 is greatly increased, the service life is longer, and the use experience is better; the width of the first bottom plate 6 can be increased as needed, thereby increasing the contact area between the first bottom plate 6 and the door frame 3. Compared with only one layer of hook surface 4 glued to the door frame 3, the first bottom plate 6 is more firmly bonded to the door frame 3, reducing the possibility of degumming and falling.

[0052] The first transverse plate 7 protrudes a certain distance to the side away from the door frame 3, and the protruding distance is equal to the sum of the thicknesses of the hook surface 4 and the rough surface 5. A fixing hole 9 is opened on the first transverse plate 7, and a self-tapping screw 10 is arranged in the fixing hole 9. The self-tapping screw 10 can penetrate the reinforcing edge cloth 2 and the gauze sheet 1; while using the first transverse plate 7 to hang the top of the middle side, the self-tapping screw 10 can be selected to penetrate the reinforcing edge cloth 2 and the gauze sheet 1 to fix the reinforcing edge cloth 2 and the first transverse plate 7, so as to further increase the supporting effect of the first transverse plate 7. The self-tapping screw 10 only penetrates the reinforcing edge cloth 2 and the gauze sheet 1, which is relatively different from the conventional method in the prior art. The nail plate needs to penetrate the hook surface 4, the rough surface 5, the reinforcing edge cloth 2 and the gauze piece 1, and the self-tapping screws 10 only penetrate the reinforcing edge cloth 2 and the gauze piece 1 which are relatively easy to penetrate, which is more convenient for installation; the first fixing plate can be stamped and formed by a metal plate, and the connecting plate 8 can be bent during stamping. The strength of the metal plate is relatively high and the anti-aging ability is relatively strong; since the first horizontal plate 7 protrudes a certain distance, it is convenient to hang the top of the middle edge of the two gauze pieces 1 on the first horizontal plate 7. When installing the first bottom plate 6, the first horizontal plate 7 can be suspended in the air, or it can be installed on a plane so that the first horizontal plate 7 is not suspended in the air, thereby increasing the use range of the screen door.

[0053] In order to facilitate the closing of the screen door, when sewing the reinforcing edge cloth 2 and the gauze sheet 1, the tops of the middle edges of the two gauze sheets 1 will overlap to a certain extent, such as Figure 2 As shown, however, during the production process, the front and rear positions of the left yarn piece 1 and the right yarn piece 1 when they overlap are random, that is, the left pressing the right and the right pressing the left may occur. Both ends of the first horizontal plate 7 can hang on the top of the middle edge of the yarn piece 1, so that the first horizontal plate 7 can be inserted between the two yarn pieces 1 under any circumstances, thereby hanging on the top of the middle edge of the yarn piece 1, which is convenient for personnel to install during use.

[0054] The yarn sheet 1 is woven from warp monofilaments 17, weft monofilaments 19 and elastic yarns 18, and a predetermined number of elastic yarns 18 are arranged in the intervals between the weft monofilaments 19; when the yarn sheet 1 is weaving, the density of the weft monofilaments 19 and the elastic yarns 18 can be changed by controlling the wire feeding speed of the warp monofilaments 17, and a certain number of elastic yarns 18 are added between the weft monofilaments 19. The materials of the warp monofilaments 17 and the weft monofilaments 19 are different. When the density of the elastic yarns 18 increases, the light transmittance of the yarn sheet 1 will decrease; the density of the elastic yarns 18 is increased locally, so that the yarn sheet 1 partially achieves the effect of a privacy door curtain. Compared with the prior art, in which the warp monofilaments 17 and the weft monofilaments 19 have the same density, after the weaving of the flat net is completed, a pattern is sewn on the flat net with thread, or a cloth piece is sewn. The production method using the elastic yarns 18 is simpler, and the integrity of the yarn sheet 1 is better, and the density of the elastic yarns 18 can be gradually changed to achieve The gradient effect is customized according to the usage requirements, so as to provide a better user experience; the flat net woven by ordinary warp monofilaments 17 and weft monofilaments 19 is prone to thread slippage when subjected to local force, resulting in local deformation of the yarn sheet 1, affecting the use of the yarn sheet 1, and the weft monofilaments 19 are used to limit the elastic wire 18. After adding the elastic wire 18, the elasticity of the elastic wire 18 is different from that of the weft monofilaments 19, so when subjected to pulling force in the horizontal direction, the elastic wire 18 can withstand the pulling force, thereby greatly reducing the thread slippage; due to the large number of elastic wires 18, in the vertical direction, the stability can also be increased to a certain extent, reducing the possibility of thread slippage; in the process of opening and closing, the screen door is generally pushed open, and is subjected to relatively more force in the horizontal direction. The tensile strength of the yarn sheet 1 in the horizontal and vertical directions is increased, thereby making the yarn sheet 1 more resistant to deformation and having a longer service life.

[0055] The warp of the reinforced edge cloth 2 is made of polyester, and the weft is made of nylon. Polyester has poor elasticity, which makes the reinforced edge cloth 2 more stable in the vertical direction and will not be deformed. It has stronger tensile resistance in the vertical direction, which can avoid the misalignment of the two gauze sheets 1 and the loss of magnetic force of the magnetic block 22. At the same time, the harder polyester material can also be easier to reset after the screen door is opened; in the horizontal direction, nylon has a little elasticity, which makes the reinforced edge cloth 2 better when wrapping the magnetic material 22, and a little elasticity in the horizontal direction also facilitates the attraction of the magnetic material 22; the reinforced edge cloth 2 made of polyester and nylon is also superior to the commonly used coated edge cloth in terms of damage resistance and service life.

[0056] The fixing strip 20 is used to fix the magnetic material 22, and the fixing strip 20 is wrapped by the reinforcing edge cloth 2; when sewing the reinforcing edge cloth 2 of the middle edge of the yarn piece 1, the fixing strip 20 is wrapped in the reinforcing edge cloth 2, and the fixing strip 20 uses a sponge material. The fixing strip 20 is uniformly provided with a fixing groove 21 in advance, and a scale line is provided on the fixing strip 20, which is convenient for production personnel to operate, and the fixing grooves 21 are uniformly provided in advance. The spacing of the fixing grooves 21 is the same. When the screen door is closed, the magnetic material 22 is accurately positioned to avoid the misalignment of the magnetic material 22 and the loss of magnetic force; in the prior art, non-woven fabric is generally used to pre-fix the magnetic material 22, and the non-woven fabric is pressed at a predetermined position to limit the position of the magnetic material 22. Whether the operator manually sews the package or uses automated equipment to sew the package, the size of the pre-fixed package must be larger than the size of the magnetic material 22, so that it can be easily sewn during sewing. The magnetic material 22 is placed in the pre-fixed package, and each yarn sheet 1 needs to be individually packaged when the package is ordered, which is prone to size errors, and the magnetic material 22 will have a certain sliding space in the pre-fixed package, which is prone to misalignment of the magnetic material 22, resulting in magnetic force loss, affecting the closing effect of the screen door; and when the non-woven fabric is used to fix the magnetic material 22, when the screen door is closed, there are two layers of non-woven fabric and two layers of reinforcing edge cloth 2 between the corresponding group of magnetic materials 22, and when the fixing strip 20 is used to fix the magnetic material 22, there are only two layers of reinforcing edge cloth 2 between the corresponding group of magnetic materials 22, the magnetic force loss of the magnetic material 22 is reduced, the relative magnetic force is increased, and it is more convenient to close the screen door, and the use experience is increased; at the same time, when the screen door is about to close and the corresponding magnetic material 22 is about to be sucked, there is a sponge on the side of the magnetic material 22 as a buffer, which can reduce the impact force of the magnetic material 22 and reduce the possibility of damage to the magnetic material 22. The cross-sectional size of the fixing groove 21 is slightly smaller than the cross-sectional size of the magnetic material 22, so that the magnetic material 22 is more stable in the fixing groove 21 and will not slide.

[0057] The magnetic material 22 includes magnetic strips, magnetic blocks or a combination thereof.

[0058] Example 2

[0059] like Figure 7 As shown:

[0060] The difference between Example 2 and Example 1 is only the difference in the middle edge reinforcement structure;

[0061] The middle edge reinforcement structure is set as a second fixed plate, and the second fixed plate includes a second bottom plate 11, and the second bottom plate 11 is arranged between the hook surface 4 and the door frame 3. A convex plate 12 for increasing strength is provided on the side of the second bottom plate 11 away from the door frame 3, and a second cross plate 13 is fixedly connected to the side of the convex plate 12 away from the second bottom plate 11, and the second cross plate 13 can hang the top of the middle part of the two gauze sheets 1; during installation, the second bottom plate 11 is fixed to a predetermined position on the door frame 3 by double-sided tape, and the hook surface 4 with adhesive backing is attached to the door frame 3, the hook surface 4 covers the second bottom plate 11, and the fur surface 5 of the edge of the gauze sheet 1 is attached to the corresponding hook surface 4, and the second cross plate 13 is inserted between the two gauze sheets 1. The second cross plate 13 is used to hang the top of the middle edge, and a rounded corner is provided at the connection between the second cross plate 13 and the convex plate 12 to increase the tensile strength;

[0062] The second fixing plate can be integrally injection molded, or only the convex plate 12 and the second transverse plate 13 can be injection molded, and then the convex plate 12 and the second transverse plate 13 are bonded to the second bottom plate 11. Using PC, PS and other materials for injection molding can reduce production costs.

[0063] Example 3

[0064] like Figure 8-Figure 10 As shown:

[0065] The difference between Example 3 and Example 1 is only the difference in the middle edge reinforcement structure;

[0066] The middle edge reinforcement structure is set as a third fixed plate, and the third fixed plate includes a third bottom plate 14 and two hook plates 15. The third bottom plate 14 is set between the hook surface 4 and the door frame 3, and the top of the third bottom plate 14 is provided with a bend, which is toward the side away from the door frame 3. The hook plate 15 is sewn between the reinforcing edge cloth 2 and the fleece surface 5. A hook plate 15 is sewn on the top of the two yarn pieces 1 on the side close to each other, and a hook that is matched with the upper bend of the third bottom plate 14 is provided on the top of the hook plate 15. During installation, the third bottom plate 14 is fixed to a predetermined position on the door frame 3 by using double-sided tape, and the hook surface 4 with adhesive backing is attached to the door frame 3. The hook surface 4 is covered on the third bottom plate 14, and the fur surface 5 on the edge of the gauze sheet 1 is attached to the corresponding hook surface 4. At the same time, the hook on the hook plate 15 is also hung on the bend of the third bottom plate 14. When the gauze sheet 1 tends to fall, the third bottom plate 14 and the hook plate 15 can support the gauze sheet 1 to prevent the gauze sheet 1 from falling, thereby making the bonding between the gauze sheet 1 and the door frame 3 more stable and increasing the service life; the hook plate 15 is pre-sewn between the fur surface 5 and the reinforced edge cloth 2, which is more convenient and easy to operate when installing the screen door; and there are two hook plates 15, which are respectively installed on the two gauze sheets 1, so as to facilitate the storage and folding of the two gauze sheets 1.

[0067] Example 4

[0068] like Figure 11-Figure 12 As shown:

[0069] The difference between Example 4 and Example 1 is only the difference in the middle edge reinforcement structure;

[0070] The middle edge reinforcement structure is set as a fourth fixed plate, and the fourth fixed plate includes two L plates 16. The L plates 16 are sewn between the reinforcing edge cloth 2 and the fleece surface 5, and one L plate 16 is sewn on each of the two gauze sheets 1. The horizontal end of the L plate 16 coincides with the reinforcing edge cloth 2 at the top of the gauze sheet 1, and the vertical end of the L plate 16 coincides with the reinforcing edge cloth 2 in the vertical direction near the middle of the gauze sheet 1. The middle edge reinforcement structure is set as an L plate. When installing, the hook surface 4 with adhesive backing is attached to the door frame 3, and the fleece surface 5 at the edge of the gauze sheet 1 is attached to the corresponding hook surface 4. The L plate is pre-sewn on the fleece surface 5 Between the gauze sheet 1 and the reinforcing edge cloth 2, the horizontal end of the L-plate 16 overlaps with the reinforcing edge cloth 2 at the top of the gauze sheet 1, and the vertical end of the L-plate 16 overlaps with the reinforcing edge cloth 2 on the vertical direction near the middle side of the gauze sheet 1. When the gauze sheet 1 tends to fall, due to the existence of the L-plate 16, the force on the top of the middle edge of the gauze sheet 1 is relatively uniform, which can avoid the situation where the hook surface 4 and the upper part of the fur surface 5 are torn first, thereby making the bonding between the gauze sheet 1 and the door frame 3 more stable. The two L-plates 16 can facilitate the storage of the gauze sheet 1, and the use of the L-plate 16 is more convenient when installing and removing the gauze sheet 1.

[0071] Example 5

[0072] like Figure 13-Figure 15 As shown:

[0073] The difference between Example 4 and Example 1 is that a protective sheet 23 is added;

[0074] A plurality of protective sheets 23 are installed at the bottom of the gauze sheet 1 to protect the bottom of the gauze sheet 1, especially when there are pets such as cats at home to prevent the cats from scratching the gauze sheet 1. At the same time, the bottom of the gauze sheet 1 is also a part that the user's feet often kick. With the protective effect of the protective sheet 23, the bottom of the gauze sheet 1 is not easy to be damaged or dirty, thereby increasing the service life of the screen door. In order to avoid the excessive weight of the protective sheet 23, the thickness of the protective sheet 23 can be set between 0.3mm and 0.5mm.

[0075] When the user needs to open the door to check the situation inside or outside the room, and needs to open the door, if there are children or other situations where the pet is not wanted to pass through the screen door, the square piece 27 on the horizontal piece 26 can be stuck in the fixed frame 28. Generally, the pet will push the screen door upward from the bottom. At this time, the bottoms of the two screen pieces 1 are equivalent to being connected together, and the bottoms cannot be opened outward, thereby preventing the pet from entering or exiting; when the pet pushes the horizontal piece 26 upward, after the horizontal piece 26 rotates a certain distance along the pin, the top of the horizontal piece 26 contacts the fixed column 29, preventing the horizontal piece 26 from continuing to rotate. At this time, one corner of the square piece 27 is still in the fixed frame 28, so the square piece 27 and the fixed frame 28 will not be separated, thereby preventing the screen door from opening from the bottom; when the user needs to open the screen door, he only needs to lift the first middle piece upward The gauze sheet 1 on one side of 24, under the action of the stopper, all the horizontal sheets 26 move up as a whole, and the horizontal sheets 26 remain in a horizontal state. Before the horizontal sheet 26 contacts the bottom of the fixing column 29, the square sheet 27 and the fixing frame 28 can be out of contact, thereby opening the screen door. The operation is simple and convenient. The reinforced edge cloth 2 is made of harder polyester material in the vertical direction, which is also convenient for the user to pull one of the gauze sheets. The two gauze sheets 1 are dislocated in the vertical direction. The fixed sheet 23 itself also strengthens the deformation resistance of the bottom of the gauze sheet 1, thereby facilitating the square sheet 27 to move out of the fixing frame 28; the fixed sheet 23 has a certain weight, and the weight of the first middle sheet 24 and the second middle sheet 25 is greater than the weight of the remaining fixed sheets 23, which can enhance the natural closing ability of the screen door.

[0076] One end of the transverse piece 26 is rotatably connected to the first middle piece 24 via a pin. When the transverse piece 26 is not in use, the transverse piece 26 is reversely rotated 270°, and the transverse piece 26 is in a naturally drooping state, which will not affect the normal opening and closing of the screen door.

[0077] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
