Description

Technical Field

[0001] The invention relates to the technical field of building-related techniques, in particular to an adjustable connecting mechanism for a curtain wall and a canopy. Background Art

[0002] As is known, a canopy is installed above the gate in front of the curtain wall in places such as shopping malls. Generally, a canopy structure is formed by laying glass panels and other materials on a horizontal support structure. The canopy structure mainly serves to prevent falling objects from high altitudes, provide shade, block rain, and serve as decoration.

[0003] The installation of the awning must ensure that its structure is stable and firm. In the existing technology, the installation structure of the awning is generally to connect one end of the awning to one side of the curtain wall, and the other end is cantilevered and reinforced by an inclined beam. During the specific installation, a rigid direct connection and fixation method is adopted. First, the connection structure is not firm enough and is prone to shaking due to strong winds. Second, after being affected by shaking, the connection rigidity is not stable enough, and subsequent maintenance and reinforcement are difficult.

[0004] Therefore, the overall installation structure of the canopy is not stable enough and is not easy to maintain in the later stage. In order to improve this situation, a canopy installation structure is designed in the patent with the announcement number CN222649263U and the announcement date of March 21, 2025, entitled "A canopy installation structure on a curtain wall", which specifically includes a building wall and a curtain wall vertically arranged in front of the building wall, and also includes: a canopy support structure, which is horizontally arranged on the side of the curtain wall opposite to the building wall; an end support connection mechanism, which is arranged at one end of the canopy support structure to fix the canopy support structure on the building wall; an inclined reinforcement rod, which is obliquely arranged between the curtain wall and the canopy support structure to reinforce and support the end of the canopy support structure opposite to the curtain wall; a first connection mechanism, which is arranged on the curtain wall at a position above the canopy support structure to connect the upper end of the inclined reinforcement rod; and a second connection mechanism, which is arranged on the end of the canopy support structure opposite to the curtain wall to connect the lower end of the inclined reinforcement rod.

[0005] Including the above, the shortcomings of the existing technology are that the inclined reinforcement rods of the awning are fixedly connected to the long cantilever beams, and the long cantilever beams are fixedly connected to the curtain wall. When affected by strong winds, the fixed positions will be worn and deformed due to shaking, and the direction of vibration is random, so the worn and deformed parts are also uncertain. Even if the connection tightness between the inclined reinforcement rods and the long cantilever beams is adjusted later, the adjustment direction is single, and it is difficult to say that the overall connection rigidity of the awning is stable enough. Obviously, in this case, the safe use of the awning is still insufficient. Summary of the Invention

[0008] As mentioned above, the third ring body is provided with an abutment surface and a support surface, the area of ​​the abutment surface is larger than that of the support surface, and the support surface is arc-shaped; when the socket body and the ball head body remain axially parallel, the abutment surface forms surface contact with the base; when the long cantilever beam is disturbed by wind and swings, the support surface forms point contact with the base.

[0009] As mentioned above, the glass plate includes a main plate and two sub-plates slidingly arranged on both sides of the main plate. The main plate is installed on the long cantilever beam through a docking claw. A first rod body is swingably provided on the long cantilever beam. The sub-plates are installed on the first rod body through a docking claw. During the swinging stroke of the long cantilever beam caused by wind disturbance, the two sub-plates are close to each other based on the swinging action of the long cantilever beam.

[0010] As mentioned above, the ball socket body is provided with a first cavity for the ball head body to be swung, and a second cavity is provided on the side of the first cavity close to the first ring body. A second rod body is provided for the axial upward sliding of the ball head body, and in the sliding direction, a second elastic member is provided between the second rod body and the long cantilever beam, and a rack is installed on the second rod body. A gear is installed at the end of each first rod body connected to the long cantilever beam, and the gear is meshed with the rack; in the swing stroke of the long cantilever beam, the wall of the second cavity produces an extrusion effect on the second rod body.

[0011] As mentioned above, the two first rods corresponding to the rack are arranged in a long V-shaped structure. When the two sub-plates approach each other, they will also approach the base.

[0012] As mentioned above, a driving motor is provided on the curtain wall, a winch is provided at the power output end of the driving motor, and a steel cable is provided between the winch and the long cantilever beam.

In this way, the coordination structure of the ball socket and the ball head is the position between the canopy and the curtain wall that is most prone to shaking due to wind force. That is, when affected by strong winds, the elastic force of the first elastic part is utilized to buffer the wind disturbance, so that the entire canopy can swing slightly to reduce the wear of the connecting mechanism. Moreover, the elastic force of the first elastic part can be adjusted, thereby increasing the elastic force of the first elastic part according to the change of elastic fatigue and the magnitude of wind force, so that the canopy can be stably installed on the curtain wall.

[0020] In order to make those skilled in the art better understand the technical solution of the present invention, Figure 1 To the attached Figure 6 The present invention is further described in detail.

[0021] In an embodiment of the present invention, an adjustable connecting mechanism for a curtain wall and a canopy is provided, which is used to install a long cantilever beam 10 on a curtain wall 1. A plurality of long cantilever beams 10 are provided, and a glass plate 11 is installed on each long cantilever beam 10 through a connecting claw 12. The adjustable connecting mechanism 2 includes a base 20 connected to the curtain wall 1, a ball socket 21 is installed inside the base 20, and a ball head 22 is installed at the end of the long cantilever beam 10, and the ball head 22 is swingably arranged in the ball socket 21; a first elastic member 23 capable of elastic adjustment is provided on the base 20, and based on the elastic force of the first elastic member 23, the ball socket 21 and the ball head 22 remain axially parallel.

[0022] Specifically, the canopy is composed of a number of long cantilever beams 10 arranged horizontally on the curtain wall 1 and a glass plate 11 installed on each long cantilever beam 10 by a connecting claw 12. The length direction of the common long cantilever beam 10 is basically perpendicular to the curtain wall 1 surface, and the two adjacent glass plates 11 are tightly fitted together. The connecting claw 12 is a commonly used glass plate 11 installation mechanism, and its structure can be adjusted according to actual needs. It is a prior art and will not be described in detail here. In the prior art, in order to ensure the stability of the canopy installation, an inclined reinforcement rod will be added between the long cantilever beam 10 and the curtain wall 1, and in order to increase the connection rigidity, an inclined reinforcement rod will be added between the long cantilever beam 10 and the curtain wall 1. A rigid adjustment mechanism is provided at the connection between the reinforcement rod and the curtain wall 1, and a rigid adjustment mechanism is also provided at the connection between the inclined reinforcement rod and the long cantilever beam 10. However, its disadvantage is that when affected by strong winds, the fixed position will be worn and deformed due to shaking, and the direction of vibration is random, so the wear and deformation part is also uncertain. In the prior art, the adjustment direction of the rigid adjustment mechanism is relatively single. Even if the connection tightness between the inclined reinforcement rod and the long cantilever beam 10 is adjusted later, it does not mean that the overall connection rigidity of the canopy is stable enough. Obviously, in this case, the safe use of the canopy is still insufficient.

[0023] Based on the above technical problems, in this embodiment, a base 20 for installation is added to the connection between each long cantilever beam 10 and the curtain wall 1. The base 20 and the curtain wall 1 are fixed by bolts. A space for installing a socket body 21 is opened inside the base 20. The socket body 21 is a cylindrical structure with a spherical groove at one end. It can be fixed inside the base 20, and then a ball head body 22 is swung inside the spherical groove. The ball head body 22 is a cylindrical rod with a spherical structure at one end. The socket body 21 and the ball head body 22 are two The two have a clearance fit, and the fitting surface is smooth. The long cantilever beam 10 is fixedly connected to the end of the ball head body 22 away from the spherical end, so that the long cantilever beam 10 can swing in any direction relative to the base 20. However, a canopy is required to prevent objects from falling from high altitudes, provide sunshade, block rain, and provide decoration. Therefore, the length direction of the long cantilever beam 10 needs to be kept perpendicular to the curtain wall 1. Therefore, a first elastic member 23 is provided on the base 20. At this time, the first elastic member 23 is used to connect the base 20 and the ball head body 22, and the elastic force of the first elastic member 23 is used to ensure that the long cantilever beam The length direction of the beam 10 is kept perpendicular to the curtain wall 1, wherein the elastic force of the first elastic member 23 is initially set to what value to ensure that the length direction of the long cantilever beam 10 is kept perpendicular to the curtain wall 1. In this embodiment, the wind force is divided into levels 0 to 12. For example, when the wind force is between 0 and 8, the elastic force provided by the first elastic member 23 can make the long cantilever beam 10 basically not swing, that is, the axial direction of the socket body 21 is kept parallel to the axial direction of the ball head body 22. When the wind force is between 8 and 12, the long cantilever beam 10 is kept parallel to the axial direction of the ball head body 22. Under the action of elastic force, it can swing in any direction with an amplitude of about 0 to 10 degrees (the above explanation is for the convenience of understanding and description, and it needs to be arranged according to specific circumstances in actual application). The elastic force of the first elastic member 23 can be adjusted, that is, the elastic member will have elastic fatigue after long-term use. In addition, according to the wind force changes in the area where the awning is located, the elastic force of the first elastic member 23 can be appropriately increased to make the installation of the awning more stable. The adjustable elastic force of the first elastic member 23 is an existing technology and will not be described in detail here.

[0024] The beneficial effect of this embodiment is that: by utilizing the swinging cooperation of the socket body 21 and the ball head body 22, the installation of the long cantilever beam 10 on the curtain wall 1 can be swung in any direction. In this way, the cooperation structure of the socket body 21 and the ball head body 22 is the position between the canopy and the curtain wall 1 that is most prone to shaking due to wind force. That is, when affected by strong winds, the elastic force of the first elastic member 23 is utilized to buffer the wind disturbance, so that the entire canopy can swing slightly to reduce the wear of the connecting mechanism. Moreover, the elastic force of the first elastic member 23 can be adjusted, thereby increasing the elastic force of the first elastic member 23 according to the change of elastic fatigue and the magnitude of wind force, so that the canopy can be stably installed on the curtain wall 1.

[0025] Preferably, the first elastic member 23 includes an adjusting rod 230 slidably arranged on the base 20, the adjusting rod 230 is threadedly connected to the ball socket body 21, a first ring body 231 is rotatably provided on the adjusting rod 230, a second ring body 232 is provided in the base 20, a spring 233 is installed between the first ring body 231 and the second ring body 232, and a third ring body 24 is installed at the end of the long cantilever beam 10, and the third ring body 24 is in contact with the base 20.

[0026] Specifically, in the aforementioned embodiment, when the long cantilever beam 10 is not swinging, the first elastic member 23 needs to ensure that the length direction of the long cantilever beam 10 is perpendicular to the curtain wall 1. When the long cantilever beam 10 swings, it needs to have a swinging force in multiple directions. Therefore, for the elastic element in the first elastic member 23, such as the spring 233, its arrangement needs to use the position change of the long cantilever beam 10, then the deformation of the spring 233 will not only need to be along its own axis but also in other directions. In this way, the spring 233 is more prone to metal fatigue, resulting in a decrease in the elastic force provided to the long cantilever beam 10.

[0027] Therefore, in this embodiment, another method is adopted, in which the elastic force of the first elastic member 23 is used to ensure that the length direction of the long cantilever beam 10 is perpendicular to the surface of the curtain wall 1 and that during the swinging of the long cantilever beam 10, the spring 233 only undergoes axial elastic deformation, that is, the socket body 21 is arranged to slide axially in the space inside the base 20 (when the length direction of the long cantilever beam 10 is perpendicular to the surface of the curtain wall 1, the length direction of the long cantilever beam 10 is parallel to the sliding direction of the socket body 21), and an adjusting rod 230 is also provided on the base 20 for sliding along this direction. The adjusting rod 230 is screwed to the socket body 21, and a first ring body 231 is provided when the adjusting rod 230 rotates, and a second ring body 232 is correspondingly provided in the space inside the base 20, and a spring 233 is connected between the first ring body 231 and the second ring body 232. At this time, the position of the second ring body 232 inside the base 20 is fixed, which is adjusted by rotation. The rod 230 can drive the first ring body 231 to move closer to or away from the ball socket body 21, and the distance between the first ring body 231 and the second ring body 232 will also change, thereby realizing the adjustment of the stretching length of the spring 233, wherein a third ring body 24 is installed at the end of the long cantilever beam 10 close to the base 20, and the third ring body 24 is in contact with the surface of the base 20 facing the long cantilever beam 10. When the long cantilever beam 10 is swung by wind disturbance, the contact point between the third ring body 24 and the base 20 can be used to form a lever structure. When the ball head body 22 and the ball socket body 21 swing relative to each other, the ball head body 22 will move in the direction away from the base 20, thereby pulling the ball socket body 21 and the adjusting rod 230 to move together, so that the spring 233 is stretched, the elastic force of the spring 233 is increased, and the elastic force of the spring 233 is used to buffer the wind disturbance on the long cantilever beam 10.

[0028] In the aforementioned embodiment, at levels 0 to 8, the elastic force provided by the first elastic member 23 can prevent the long cantilever beam 10 from swinging basically. At levels 8 to 12, the long cantilever beam 10 can swing with an amplitude of about 0 to 10 degrees in any direction under the elastic force of the first elastic member 23. Based on this, in an optional embodiment, the third ring body 24 is provided with an abutment surface 240 and a support surface 241, the area of ​​the abutment surface 240 is larger than the support surface 241, and the support surface 241 is arc-shaped; in the process of the socket body 21 and the ball head body 22 remaining axially parallel, the abutment surface 240 forms a surface contact with the base 20; in the process of the long cantilever beam 10 swinging due to wind disturbance, the support surface 241 forms a point contact with the base 20.

[0029] Specifically, when the long cantilever beam 10 is not swung by wind disturbance, the abutting surface 240 is in surface contact with the base 20, and the surface contact forms multiple points of support in the circumferential direction, so that the wind resistance of the long cantilever beam 10 is enhanced, and when the wind force is between 0 and 8, the elastic force of the spring 233 can be used to resist the wind disturbance. When the wind force is between 8 and 12, the supporting effect of the surface contact and the elastic force of the spring 233 at this time are insufficient to prevent the long cantilever beam 10 from swinging, and the arc-shaped supporting surface 241 on the third ring body 24 is in contact with the base 20, and as the long cantilever beam 10 swings, the contact between the supporting surface 241 and the base 20 The contact position changes accordingly, but due to the cooperation between the socket body 21 and the ball head body 22, the position of the point contact between the support surface 241 and the base 20 will change with the swing amplitude of the long cantilever beam 10, forming a lever support point for the swing of the long cantilever beam 10, that is, the abutment surface 240 can increase the contact area with the base 20, so that the long cantilever beam 10 can basically not swing under certain wind disturbances, and point contact is formed between the arc-shaped support surface 241 and the base 20, providing point support for the long cantilever beam 10 when it swings due to wind disturbances, so as to reduce swing restrictions and wear, thereby facilitating the use of the elastic force of the spring 233 to buffer wind disturbances.

[0030] Preferably, the glass plate 11 includes a main plate 110 and two sub-plates 111 slidingly arranged on both sides of the main plate 110. The main plate 110 is installed on the long cantilever beam 10 through a docking claw 12. A first rod body 112 is swingably provided on the long cantilever beam 10. The sub-plates 111 are installed on the first rod body 112 through the docking claw 12. During the swinging stroke of the long cantilever beam 10 caused by wind disturbance, the two sub-plates 111 are close to each other based on the swinging action of the long cantilever beam 10.

[0031] Specifically, in the prior art, the canopy is composed of a number of long cantilever beams 10 arranged horizontally on the curtain wall 1 and a glass plate 11 installed on each long cantilever beam 10 through a docking claw 12. It is an integral structure with a large wind-exposed area. When disturbed by wind, the entire structure will shake, which will cause a rigid interaction force between two adjacent glass plates 11, which may seriously cause damage to the glass plates 11. Therefore, in this embodiment, the glass plates 11 corresponding to each long cantilever beam 10 are arranged in a split manner, that is, each glass plate 11 includes a main plate 110 connected to the long cantilever beam 10, and two sub-plates 111 slidably arranged on both sides of the width direction of the main plate 110. During the swinging process of the long cantilever beam 10, the two sub-plates 111 can be close to each other under the action of external force, so that the interaction between the glass plates 11 corresponding to the two adjacent long cantilever beams 10 will be reduced, and the rigid effect will disappear, thereby protecting the glass plates 11.

[0032] Furthermore, the socket body 21 is provided with a first cavity 211 for the ball head body 22 to be swung, and a second cavity 212 is provided on the side of the first cavity 211 close to the first ring body 231. A second rod body 113 is provided for sliding in the axial direction of the ball head body 22, and in the sliding direction, a second elastic member 114 is provided between the second rod body 113 and the long cantilever beam 10, and a rack 115 is installed on the second rod body 113. A gear 116 is installed at the end of each first rod body 112 connected to the long cantilever beam 10, and the gear 116 is engaged with the rack 115; during the swing stroke of the long cantilever beam 10, the wall of the second cavity 212 exerts an extrusion effect on the second rod body 113.

[0033] Specifically, in the aforementioned embodiment, the swing of the long cantilever beam 10 is utilized to cause the two sub-plates 111 at the adjacent positions between the two adjacent glass plates 11 to interact with each other, and the two sub-plates 111 corresponding to each long cantilever beam 10 are brought closer to each other, so that the rigid effect disappears. However, the swing direction of the long cantilever beam 10 is random, and the direction of the action between the glass plates 11 is difficult to determine. Therefore, in order to further protect the glass plates 11 from being damaged, in this embodiment, the second rod 113 is squeezed by the wall of the second cavity 212 to drive the rack 115 to move. The rack 115 drives the gear 116 to rotate, and the gear 116 drives the first rod 112 to swing, so that the sub-plate 111 is passively moved toward the corresponding long cantilever beam 10, rather than relying on the squeezing between the glass plates 11 and the glass plates 11, so that the glass plates 11 can be better protected. The second rod 113 includes a first section slidably arranged on the ball head 22 and a second section slidably arranged on the long cantilever beam 10, and the two are abutted by the elastic force of the second elastic member 114, so as to facilitate the disassembly and assembly of the second rod 113.

[0034] In an optional embodiment, the two first rod bodies 112 corresponding to the rack 115 are arranged in a long V-shaped structure, and when the two sub-plates 111 approach each other, they will also approach the base 20; specifically, since the swing point of the long cantilever beam 10 is at the ball head body 22 and the ball socket body 21, the end of the long cantilever beam 10 away from the base 20 swings at the same angle as the end close to the center, and the swing path of the end of the long cantilever beam 10 away from the base 20 is longer. Therefore, the two first rod bodies 112 corresponding to each rack 115 are arranged in a V-shaped structure, and when the two sub-plates 111 approach each other, they can also approach the base 20, so that the center of the glass plate 11 is offset toward the base 20, and the stability of the long cantilever beam 10 will be effectively improved.

[0035] Preferably, the curtain wall 1 is provided with a drive motor, a winch 13 is provided at the power output end of the drive motor, and a steel cable 14 is provided between the winch 13 and the long cantilever beam 10; specifically, when the swing amplitude of the long cantilever beam 10 exceeds the amplitude of about 0 to 10 degrees mentioned in the aforementioned embodiment, the canopy should be protected, that is, in this embodiment, the drive motor is used to drive the winch 13 to rotate, and then the steel cable 14 is wound to pull the canopy to flip upward, preferably flip upward 90 degrees or more, that is, in the optional embodiment, a notch 210 is provided on the socket body 21, and when the part of the ball head body 22 connected to the long cantilever beam 10 completely enters the notch 210, the long cantilever beam 10 flips upward at an angle of 90 degrees, so that the canopy can be better protected when disturbed by wind. The drive motor, winch 13 and steel cable 14 are all existing technologies and will not be repeated.

[0036] Preferably, the radial dimensions of the first cavity 211 and the second cavity 212 are the same; when the long cantilever beam 10 does not swing, based on the elastic force of the second elastic member 114, the length of the end of the second rod body 113 on the ball head body 22 extending therefrom is the longest; in the swinging stroke of the long cantilever beam 10 in any direction, based on the squeezing effect of the wall of the second cavity 212, the length of the end of the second rod body 113 on the ball head body 22 extending therefrom gradually shortens; when the long cantilever beam 10 is flipped upward at an angle of 90 degrees, the end of the second rod body 113 on the ball head body 22 is completely retracted into the ball head body 22.

[0037] Specifically, for each of the two sub-plates 111 corresponding to the long cantilever beam 10, the distance between the two sub-plates 111 and the first sub-plates 211 should change with the swing amplitude of the long cantilever beam 10 during the swinging process of the long cantilever beam 10, that is, the radial dimensions of the second cavity 212 and the first cavity 211 are set to be the same. When the long cantilever beam 10 does not swing, based on the elastic force of the second elastic member 114, the length of the end of the second rod body 113 on the ball head body 22 extending is the longest. When the ball head body 22 swings in the first cavity 211, the second rod body 113 will be squeezed by the wall of the second cavity 212 and change accordingly with the change of the swing amplitude. In this way, the moving distance of the sub-plate 111 becomes larger as the swing amplitude of the long cantilever beam 10 increases. When the two sub-plates 111 at similar positions corresponding to the two long cantilever beams 10 can avoid mutual collision, the distance between the two is controlled within an appropriate range according to the wind disturbance, which can still play a certain role in preventing falling objects from high altitude, shading and keeping out rain.

[0038] Furthermore, the second ring body 232 is slidably arranged in the base 20, and a third rod body 25 is also slidably provided on the base 20, and a third elastic member 26 is provided between the third rod body 25 and the base 20. A first slot 27 is opened on the second ring body 232, and a first plug rod 28 is installed on the third rod body 25. Based on the elastic force of the third elastic member 26, the first plug rod 28 tends to be plugged into the first slot 27, and an extrusion block 29 is provided on the socket body 21. When the long cantilever beam 10 needs to be flipped upward at an angle of 90 degrees, the extrusion block 29 squeezes the third rod body 25 to drive the first plug rod 28 to disengage from the first slot 27, so as to release the lock on the second ring body 232.

[0039] Specifically, when the long cantilever beam 10 needs to be flipped upward at an angle of 90 degrees, the spring 233 of the first elastic member 23 is stretched to generate a force to resist its flipping. At this time, the canopy is protected and the elastic force of the spring 233 is not needed to resist wind disturbance. Therefore, in this embodiment, a first slot 27 is opened on the second ring body 232, and the second ring body 232 can slide along the axial direction of the adjusting rod 230 inside the base 20, and then the third rod body 25 is slidably set on the base 20, and the first plug rod 28 is set on the third rod body 25. When the canopy does not need to be protected, it means that the long cantilever beam 10 is disturbed by wind and the swing is within a reasonable range. In this case, the elastic force of the spring 233 is needed to resist the wind, that is, the third elastic member 25 is used to The elastic force of the elastic member 26 causes the third rod 25 to drive the first insertion rod 28 to be plugged into the first slot 27 to limit the position change of the second ring body 232. When the awning needs to be protected, it means that the swing amplitude of the long cantilever beam 10 has exceeded a reasonable range. The movement of the socket body 21 will drive the extrusion block 29 to squeeze the third rod 25, so that the third rod 25 drives the first insertion rod 28 to be disengaged from the first slot 27, thereby releasing the restriction on the position of the second ring body 232. The position where the third rod 25 is squeezed by the extrusion block 29 is an inclined structure, that is, there is a wedge-shaped fit between the extrusion block 29 and the third rod 25 to form an extrusion action structure, so that when the awning is flipped upward 90 degrees, the elastic force of the spring 233 will not hinder it.

[0040] Furthermore, when the awning is flipped upward by 90 degrees, the pulling force on it comes from the steel cable 14. Therefore, in order to better limit the position of the flipped awning, this embodiment further installs a second plug rod 30 on the third rod body 25, and provides a second slot 31 at the end of the long cantilever beam 10 close to the base 20, that is, after the extrusion block 29 squeezes the third rod body 25 to disengage the first plug rod 28 from the first slot 27, the long cantilever beam 10 will be flipped upward by 90 degrees, which will drive the second slot 31 to gradually connect with the second plug rod 30. By utilizing the elastic force of the third elastic member 26, the second plug rod 30 is connected with the second slot 31 to lock the position of the long cantilever beam 10, thereby better stabilizing the long cantilever beam 10. At this time, the position of the extrusion block 29 is in contact with the second plug rod 30, and the second plug rod 30 follows the ball socket body of the extrusion block 29. 21 is restricted in axial movement along the adjusting rod 230 (the socket body 21 moves in a direction away from the base 20), that is, when the awning needs to be flipped to a horizontal position, the socket body 21 can be driven to move by pushing the adjusting rod 230, and the socket body 21 and the ball head body 22 form relative movement, that is, the ball head body 22 enters the second cavity 212, and the socket body 21 drives the extrusion block 29 to push the second plug rod 30 to disengage from the second slot 31, then the position lock of the long cantilever beam 10 is released, and then the driving motor drives the winch 13 to flip and rotate, releasing the steel cable 14, so that the awning gradually returns to a horizontal state. In the process of the long beam swinging back to the horizontal position, the ball head body 22 also generates a thrust on the socket body 21, so that the second ring body 232 returns to the initial position, and under the elastic force of the third elastic member 26, the first plug rod 28 is plugged into the first slot 27 again.
