The upper end of the top tube and the ropes at various locations can be used to fix the pergola fabric. The outer ropes pass through the extension tube end rope support at the outer end of the extension tube. After the outer ropes are tightened, a closed loop is formed to hold up the extended fabric.

[0008] A further solution is that the hinge of the rigid hinge device and the upper and lower hinges of the cross-plane rigid hinge device are hinged engagement structures for clamping long grooves, which are hinged with the rigid hinge at the other side end through an eccentric hole in the same plane, and the horizontal cross tube or straight hinge tube fixed to the rigid hinge at the other side end extends a certain length in the direction of the rigid hinge of the clamping long groove structure; one end of the rigid hinge is fixed to the horizontal cross tube or the straight hinge tube, and the other end is also a clamping long groove structure, and the clamping long groove structure is along the hinge point. The cross tubes are connected to the horizontal cross tubes on different planes and the straight cross tubes on different planes through the same hinge point on the axis line; the axes of the clamped long groove structures on the upper hinge of the cross plane rigid hinge device and the lower hinge of the cross plane rigid hinge device deviate from the center line of the upper and lower hinges of the cross plane rigid hinge device, and are symmetrically tangentially radially arranged. On the upper and lower hinges, those are respectively connected to the straight cross tubes on the inner side of the cross plane, the oblique cross tubes on the inner side of the cross plane, the single cross tubes, the horizontal single cross tubes and the oblique cross tubes. The hinge points of the single cross tube hinges are either hinged with the same hole axis in pairs, or deviate from the same hole axis by a certain distance, and then hinged in parallel with each other. When the folding awning is unfolded, the axis lines of the side horizontal cross tube and the middle horizontal cross tube, the middle horizontal cross tube and the middle horizontal cross tube, the straight cross tube on the inner side of the cross plane and the straight cross tube on the outer side of the cross plane are either basically on the same axis line, or basically parallel, and their top crossing angles are less than 5 degrees. At the same time, the horizontal single cross tube and the oblique single cross tube, or the cross plane The inner straight cross tube and the oblique cross tube can also be hinged and clamped by the long clamping grooves on the upper and lower hinges of the matching cross plane rigid hinge device. After the awning is unfolded, the horizontal cross tube and the straight cross tube either fall into the long clamping groove structure of the rigid hinge or fall into the long clamping groove structure extended from the rigid hinge, so that the horizontal cross tube and the straight cross tube are rigidly connected. At the same time, the straight cross tube and the single cross tube on the inner side of the cross plane also fall into the long clamping grooves of the upper and lower hinges of the cross plane rigid hinge device, so as to achieve a rigid connection of clamping engagement.

[0009] A further solution is: the above-mentioned one-way locking device, vertical tube one-way sliding sleeve device and leg one-way sliding sleeve device, wherein the lock sleeve of the one-way locking device, the sliding sleeve of the vertical tube one-way sliding sleeve device and the leg sliding sleeve of the leg one-way sliding sleeve device can all slide unidirectionally on the vertical sleeve or the leg tube, the locking tongue is pin-hinged on the locking sleeve or the sliding sleeve, and the spring is either installed behind the locking tongue or in front of the locking tongue, pushing the locking tongue to always be close to or telescope against the side wall of the leg tube, the side wall of the vertical sleeve or the side wall of the leg tube, thereby realizing one-way clutch locking. The one-way locking device is one-way locking and has stepless adjustment. In the free state, the telescopic leg tube can be smoothly pulled downward, and locked when moving upward; similarly, the vertical tube one-way sliding sleeve device and the leg one-way sliding sleeve device are also one-way locking and have stepless adjustment. In the free state, the vertical tube one-way sliding sleeve device and the leg one-way sliding sleeve device can be smoothly pushed upward on the vertical sleeve or the leg tube, and locked when moving downward; only when the lock tongue is pressed or pushed open, the one-way locking device, the vertical tube one-way sliding sleeve device and the leg one-way sliding sleeve device can be unlocked, and the telescopic leg tube, the vertical tube one-way sliding sleeve and the leg one-way sliding sleeve can move up and down freely, and the folding shed can be folded. The one-way locking device can also include a lock lining and a rivet. The lock sleeve of the one-way locking device is fixed to the bottom of the vertical sleeve by the rivet, and the lock lining is hinged to the lock lining by an elastic pin.

[0010] A further solution is that the horizontal cross ropes and the oblique cross ropes are arranged diagonally and tightened at the top of the folding pergola, and the oblique side orthogonal ropes are arranged obliquely and tightened. The horizontal cross ropes cross through the holes in the lower part of the top tube and are fixed at the diagonal part of the truss at the top of the pergola, or are connected to the top of the extension tube. The oblique cross ropes cross through the holes in the top tube, the single top tube, the telescopic top tube, or the top of the cross plane rigid hinge device, and are respectively fixed at the diagonal part of the top of the folding pergola or connected to the top of the extension tube; the oblique side orthogonal ropes cross through the holes in the upper part of the top tube and are respectively fixed at the hinges of the four cross tubes on the top of the folding pergola. The horizontal annular ropes are connected to the fixed supports on all sides and are tightened to form a rectangle. When the folding pergola is unfolded, the horizontal cross ropes, the oblique cross ropes, the oblique side orthogonal ropes and the horizontal annular ropes are tightened to tighten the four corners of the pergola, which improves the system rigidity of the pergola on the one hand, and at the same time The shape of the fabric on the top of the pergola can also be supported. The outer edge rope is connected to the extension tube end rope support at the outer end of the extension tube. When the folding pergola is unfolded, the horizontal cross rope and the oblique cross rope are tightened, the extension tube is pulled up, and the outer edge rope arranged in the annular direction is also lifted and tightened to form a closed rectangular shape. On the one hand, the system rigidity of the pergola is improved, and at the same time, the shape of the fabric on the top of the pergola can also be supported. The horizontal parallel ropes are connected to the sliding side tubes to form a horizontal parallel arrangement. Various ropes can be connected to the pergola top fabric by pasting, bolting, velcro, etc., so that the fabric and truss of the folding pergola have better integrity and better wind resistance. The horizontal cross ropes, oblique cross ropes, oblique side orthogonal ropes, outer edge ropes and horizontal parallel ropes are flexible ropes, or elastic, partially elastic, or inelastic, or flexible steel wire ropes, or plastic, cotton, linen ropes, or their combination. To ensure that the shape of the unfolded folding pergola is more regular.

[0011] A further solution is: the above-mentioned four-corner extension ceiling device, wherein the extension tube is respectively hinged with the fixed extension support, the sliding extension support and the hinge support, and the extension tube is hinged with them by ordinary hinge, sliding hinge, or rigid hinge after being fixed with the hinge support, wherein the axis of the hinge hole of the hinge support and the extension tube deviates from the angle of the hinge hole by 10 to 70 degrees; the axis of the hinge hole is mutually orthogonal, the horizontal cross rope and the oblique cross rope are connected to the upper end of the extension tube, and the outer rope is connected to the extension tube end rope support at the outer end of the extension tube. When the folding pergola is unfolded, the horizontal cross rope and the oblique cross rope are tightened, the extension tube can be pulled up, and the outer rope is tightened to form a closed rectangular shape, which supports the extension fabric of the pergola.

[0012] A further solution is: when the total number of cross groups composed of the horizontal cross tubes and the oblique cross tubes, the middle horizontal cross tubes and the middle oblique cross tubes on one of the four sides of the folding awning is an odd number, a fixed support is installed on the vertical sleeve at one corner, or a sliding extension support or a fixed extension support in the four-corner extension ceiling device is installed, and a sliding support is required to be installed on the vertical sleeve at the other adjacent corner, and a rope support or a fixed extension support in the four-corner extension ceiling device is equipped on the top of the vertical sleeve, and a two-way limit block is fixed at a certain position between the sliding support and the vertical sleeve sleeve or the vertical sleeve one-way sliding sleeve device, which can limit the sliding height of the vertical sleeve sleeve and the downward sliding range of the sliding support. When the total number of cross groups on one side is an even number, the tops of the four-corner vertical sleeves are all equipped with fixed supports or sliding extension supports or fixed extension supports in the four-corner extension ceiling device, and a one-way limit block is fixed at a certain position below the top of the vertical sleeve sleeve to limit the sliding height of the vertical sleeve sleeve or the vertical sleeve one-way sliding sleeve.

[0013] A further solution is: the above-mentioned deflection hinge has one end fixed to the side tube through a hinge hole, and the other end hinged to the middle oblique cross tube through a hinge hole, the two hinge holes are located on the same axis, the cross-sectional shape of the deflection hinge is in the shape of a liquid crystal digital font 6 or 9, and a space larger than the thickness of the middle horizontal cross tube 4 is left on the axis of the two hinge holes.

[0014] A further solution is that the upper and lower hinges of the rigid hinged device and the cross plane rigid hinged device are made of metal or non-metallic materials such as plastic, and the various pipes can be steel pipes or high-strength fiber plastic pipes - glass fiber reinforced plastic pipes.

[0015] The present invention adopts the above technical solution, which has the advantages of:

[0016] 1. The use of rigid cross-hinged trusses and a flexible and elastic rope tensioning structure can greatly reduce the material consumption of the folding awning, thereby reducing the manufacturing cost.

[0017] 2. The folding awning of the present invention adopts a rigid hinged structure, which greatly improves the hinged rigidity compared with the traditional folding awning.

[0018] 3. Since flexible ropes are used to replace some pipes, the weight of the folding awning is greatly reduced, making it particularly suitable for portability and travel.

[0019] 4. Using soft elastic ropes as a supporting method for the pergola fabric is also a unique idea of ​​the present invention, which helps to improve the wind resistance and rain-repelling performance of the pergola, while improving the appearance of the pergola.

[0020] 5. The rigid hinged structure of the folding pergola can make up for the problem of low rigidity of the pergola system caused by the use of high-strength fiber plastic-glass reinforced plastic pipes, thereby making the folding pergola both light and cheap.

[0021] 6. Multiple groups of rigid hinged structures are compositely hinged, which can not only form a regular rectangular fabric projection pergola, but also facilitate the formation of a general rectangular or even polygonal face projection pergola, meeting the structural needs of folding pergolas of different shapes.

After being mutually hinged in multiple groups, the tube and the middle oblique cross tube are hinged to each other through multiple groups, and then hinged to the fixed support on the vertical sleeve at another adjacent side angle or the vertical tube one-way sliding sleeve through the side horizontal cross tube. The side oblique cross tube is hinged to the fixed support on the vertical sleeve, or to the vertical tube sliding sleeve or the vertical tube one-way sliding sleeve, or to the sliding support on the vertical sleeve. After cross-hinging, there are one-way limit blocks or two-way limit blocks for limiting. When unfolding the folding pergola, the tube axis center lines of the side horizontal cross tube, the rigid hinge device and the middle horizontal cross tube are either concentric or basically parallel, and the top crossing angle is less than 5 degrees. A one-way locking device is installed at the lower part of the vertical sleeve, and the telescopic leg tube can be telescoped, slid and locked in the one-way locking device and the vertical sleeve. The shed can also be equipped with a four-corner extension ceiling device, with a sliding extension support, a fixed extension support, a sliding pin, and an extension tube fixedly hinged or slidably hinged thereto installed on the top of the vertical sleeve; horizontal cross ropes are connected to the fixed support, the rope support or the upper end of the extension tube, and the horizontal cross ropes 18 cross and pass through the holes in the lower part of the top tube, and are fixed at the diagonals of the four corners of the top of the folding shed, or are connected to the tops of the extension tubes 102 and 113 at the four corners. When the folding shed is unfolded, the horizontal cross ropes are tightened, which can tighten the diagonals of the shed and lift the top tube upward. At the same time, the tightened horizontal cross ropes can also pull up the extension tubes arranged at the four corners, forming an extension and unfolding of the ceiling canopy fabric, thereby greatly improving the system rigidity of the shed.The folding pergola can also be equipped with oblique cross ropes 30 and oblique side orthogonal ropes 31. The oblique cross ropes 30 and oblique side cross ropes 31 cross and pass through the upper holes of the top tube and are respectively fixed at the diagonals of the four corners of the top of the folding pergola and the hinges of the four side cross tubes. The oblique cross ropes can also be directly connected to the top of the extension tube like the horizontal cross ropes. When the folding pergola is unfolded, the extension tube is pulled up, and the extension tube end rope support is installed at the outer edge of the extension tube. The outer edge rope is connected to the rope support on the extension tube end. The upper part of the top tube and various ropes can be used to fix the pergola fabric; the two sides of the folding pergola can also be equipped with deflection hinges. After the side tubes are fixed to the deflection hinges, they slide through the side tube sliding sleeves. The horizontal parallel ropes are fixed to the upper ends of the side tubes, and the two sides are arranged symmetrically or diagonally. When folding the folding shed, firstly, the vertical tube sliding sleeve or the unlocked vertical tube one-way sliding sleeve device is pulled downward along the vertical sleeve to drive various cross tubes to move, and the vertical sleeves at the four corners gradually come together, then, the one-way locking device is unlocked, and the vertical sleeves at the four corners move downward along the telescopic leg tubes to reduce the height of the folding shed, and finally the folding shed is completely folded; when unfolding the folding shed, first, the unlocking is cancelled to make the one-way locking device and the vertical tube one-way sliding sleeve device in a working state that can be self-locked in one direction, and then the vertical tube sliding sleeve or the vertical tube one-way sliding sleeve device is pushed upward to the one-way limit block and the two-way limit block to drive various cross tubes to move, and the vertical sleeves at the four corners gradually separate to the surroundings to achieve a plane unfolding, and then, the telescopic leg tube is pulled downward to the required height to realize the complete unfolding of the folding shed; at the same time, under the action of each cross tube, the top tube also moves upward, the horizontal cross ropes and the oblique cross ropes are tightened, the extension tube is pulled up, the outer edge rope is tightened, and the tightening is a closed rectangular shape to support the extended fabric of the shed.

[0095] Furthermore, the hinged parts of the rigid hinged device are hinged meshing structures with long troughs, which are hinged with the rigid hinged parts 8, 11, 29 at the other side end through eccentric holes 8.1, 10.1, 29.1 in the same plane, and the horizontal cross tube fixed with the rigid hinged parts 8, 11, 29 at the other side end extends a certain length in the direction of the rigid hinged parts 7, 9, 10, 28 with the long trough structure; one end of the rigid hinged parts 50, 65 is fixed on the horizontal cross tube, and the other end is also a long trough structure, which also extends a certain distance outward along the hinge points 50.1, 65.01. The horizontal cross tubes in different planes are hinged respectively through the same hinge points 50.1 and 65.01 on the axis line; when the folding awning is unfolded, the axis lines of the side horizontal cross tube and the middle horizontal cross tube, and the middle horizontal cross tube and the middle horizontal cross tube are either basically on the same axis line, or basically parallel, and their top crossing angles are less than 5 degrees. After the folding awning is unfolded, the horizontal cross tubes either fall into the long groove-shaped hinged meshing structure of the rigid hinge parts in the same plane, or fall into the long groove-shaped structure extended by the rigid hinge parts 50 and 65 in parallel planes, so that the horizontal cross tubes are rigidly connected.

[0096] Furthermore, the lock sleeve 14 of the one-way lock device and the sliding sleeve 60 of the vertical tube one-way sliding sleeve device can both slide unidirectionally on the vertical sleeve. The lock tongue 15 is hinged to the lock sleeve or the sliding sleeve by the pin 26. The spring is either installed behind the lock tongue or in front of the lock tongue to push and press the lock tongue to always be close to the side wall of the telescopic leg tube or the side wall of the vertical sleeve, thereby realizing one-way clutch locking. The one-way locking device is one-way locking and has stepless adjustment. In the free state, the telescopic leg tube can be smoothly pulled downward, and locked when it moves upward; similarly, the vertical tube one-way sliding sleeve device is also one-way locking and has stepless adjustment. In the free state, the vertical tube one-way sliding sleeve device can be smoothly pushed upward on the vertical sleeve, and locked when it moves downward; only when the lock tongue is pressed or pushed open, the one-way locking device and the vertical tube one-way sliding sleeve device can be unlocked, and the telescopic leg tube and the vertical tube one-way sliding sleeve can move up and down freely, and the folding shed can be folded. The one-way locking device also includes a lock lining and rivets. The lock sleeve of the one-way locking device is fixed to the bottom of the vertical sleeve by rivets, and is hinged to the lock lining by an elastic pin.

[0097] Furthermore, the horizontal cross ropes 18 and the oblique cross ropes 30 are arranged diagonally and tightened at the top of the folding pergola, and the oblique side orthogonal ropes 31 are arranged obliquely and orthogonally and tightened. The horizontal cross ropes 18 cross through the holes at the bottom of the top tube 17 and are fixed at the diagonal parts of the trusses at the top of the pergola, or are connected to the top of the extension tubes. The oblique cross ropes 30 cross through the holes at the top of the top tube 17 and are respectively fixed at the diagonal parts of the top of the folding pergola or are connected to the top of the extension tubes; the oblique side orthogonal ropes 31 cross through the holes at the top of the top tube 17 and are respectively fixed at the hinges of the four cross tubes at the top of the folding pergola. When the folding pergola is unfolded, the horizontal cross ropes, the oblique cross ropes and the oblique side orthogonal ropes are tightened, which can tighten the four corners of the pergola, thereby improving the system rigidity of the pergola and supporting the pergola at the same time. The shape of the fabric on the top of the shed, the outer edge ropes 105 and 115 are connected to the extension tube end rope support at the outer end of the extension tube. When the folding shed is unfolded, the extension tube is pulled up, and the outer edge ropes arranged in the annular direction are also lifted and tightened. The horizontal parallel ropes 19 are connected to the slidable side tubes 22 to form a horizontal parallel arrangement. Various ropes can be connected to the fabric on the top of the shed by pasting, bolting, velcro, etc., so that the fabric and truss of the folding shed have better integrity and better wind resistance. The horizontal cross ropes 18, the oblique cross ropes 30, the oblique side orthogonal ropes 31, the outer edge ropes 105, 115 and the horizontal parallel ropes 19 are flexible ropes, or elastic, partially elastic, or inelastic, or flexible steel wire ropes, or plastic, cotton, linen and other ropes, or their combination. To ensure that the shape of the folding shed after unfolding is more regular, wherein the flexible steel wire ropes are in the form of multiple strands, and their strength and rigidity are the highest.

[0098] Furthermore, in the extension ceiling device arranged at the four corners, the extension tubes 102 and 113 are respectively hinged with the fixed extension supports 110 and 112 and the sliding extension support 101. The hinge between the extension tube and them can be a common hinge 110.1 and 112.1, or a sliding hinge 101.1. The horizontal cross ropes and the oblique cross ropes are connected to the upper ends of the extension tubes, and the outer ropes are connected to the extension tube end rope supports at the outer ends of the extension tubes. When the folding pergola is unfolded, the horizontal cross ropes and the oblique cross ropes are tightened, the extension tubes can be pulled up, and the outer ropes are tightened to form a closed rectangular shape, thereby supporting the extension fabric of the folding pergola.

[0099] Furthermore, when the total number of cross groups composed of the side horizontal cross tubes and the side oblique cross tubes, the middle horizontal cross tubes and the middle oblique cross tubes on one of the four sides of the folding shed is an odd number, a fixed support is installed on the vertical sleeve at one corner, or a sliding extension support 101 or a fixed extension support 110 in the four-corner extension ceiling device is installed, and a sliding support 53 is required to be installed on the vertical sleeve at the other adjacent side corner, and a rope support 54 or a fixed extension support 112 in the four-corner extension ceiling device is installed on the top of the vertical sleeve. A two-way limit block 57 is fixed to the top of the vertical pipe sleeve at a certain position between the sliding support and the vertical pipe sliding sleeve or the vertical pipe one-way sliding sleeve device, which can limit the sliding height of the vertical pipe sliding sleeves 13 and 55 and the downward sliding range of the sliding support. When the total number of cross groups on one side is an even number, the tops of the vertical sleeves at the four corners are all equipped with fixed supports or sliding extension supports or fixed extension supports in the four-corner extension ceiling device, and the one-way limit block is fixed to a certain position below the top of the vertical pipe sleeve 1. The sliding height of the vertical tube sliding sleeve or the vertical tube one-way sliding sleeve is limited, and at the same time, the axis lines of each side horizontal cross tube and the middle horizontal cross tube are made as concentric or parallel as possible, thereby realizing the rigid articulation of the cross tube and the effects of self-locking at a small friction angle and self-locking at the dead point.

[0100] Furthermore, the deflection hinge 20 has one end fixed to the side tube 22 through a hinge hole 20.1, and the other end hinged to the middle oblique cross tube 6 through a hinge hole 20.2. The two hinge holes 20.1 and 20.2 are located on the same axis. The cross-sectional shape of the deflection hinge 20 is in the shape of a liquid crystal digital font 6 or 9. A space 20.3 greater than the thickness of the middle horizontal cross tube 4 is left on the axis of the two hinge holes 20.1 and 20.2 so that there will be no interference when the folding shed is folded.

[0101] Furthermore, the rigid hinged device can be made of metal or non-metallic material, such as non-metallic material, such as plastic, etc., or various pipe fittings can be steel pipes, or large-section thin-walled high-strength fiber plastic pipes - fiberglass pipes. The latter is conducive to further reducing the weight and manufacturing cost of the folding shed.

When the folding pergola is unfolded, the horizontal annular rope is tightened to tighten the four corners of the folding pergola, which improves the system rigidity of the pergola and also supports the shape of the fabric on the top of the pergola. The folding pergola is also equipped with an oblique cross rope 30, which crosses through the hinge 80 on the cross plane rigid hinge device or the upper hole of the top pipe, and is respectively fixed on the fixed supports at the top of the four corners of the folding pergola, or can also be connected to the top of the extension pipe. The outer edge of the extension pipe is equipped with an extension pipe end rope support 104, 114, and the outer ropes 105, 115 are connected to the extension pipe end rope support. When folding the folding pergola, first pull the vertical pipe sliding sleeve or the unlocked vertical pipe one-way sliding sleeve device downward along the vertical sleeve to drive the various radially distributed cross pipes to move, and the vertical sleeves at the four corners gradually approach Then, unlock the one-way lock device, let the vertical sleeves at the four corners move downward along the telescopic leg tubes, so that the height of the folding pergola is lowered, and finally the folding pergola is completely folded; when unfolding the folding pergola, first cancel the unlocking, let the one-way lock device and the vertical tube one-way sliding sleeve device be in a working state that can be self-locked in one direction, push the vertical tube sliding sleeve or the vertical tube one-way sliding sleeve device upward to the one-way limit block and the two-way limit block, drive various cross tubes to move, and the vertical sleeves at the four corners gradually separate to the surroundings to achieve plane unfolding, and then pull out the telescopic leg tubes downward to the required height to realize the complete unfolding of the folding pergola; at the same time, under the action of each radial cross tube, the top tube or the hinge on the cross plane rigid hinge device also moves upward, the horizontal annular rope 72 and the oblique cross rope are tightened, pull up the extension tube, tighten the outer rope, tighten it into a closed rectangular shape, and support the extended fabric of the pergola. ;
