Description

Technical Field

[0001] The invention belongs to the field of building structures, and more specifically relates to a canopy. Background Art

[0002] Awnings are a kind of building assembly used to block rain, wind and prevent injuries from falling objects from high altitude. Existing awnings mainly include steel support frames and sheet materials covering and fixed thereon, and the sheet materials can be tempered glass, membrane materials, metal plates and fiberglass; the above-mentioned awnings can block rain and prevent falling objects from high altitude, and at the same time have certain wind resistance; however, due to the changes in climate, frequent extreme weather and high wind levels, the wind resistance of existing forms of awnings has certain problems, and the probability of awnings being blown over increases. In order to make the awnings have a higher wind resistance effect, there are two conventional methods, one is to reinforce the support frame, and the other is to open ventilation holes on the awning. The first method is costly and the overall structural mass is large, and effective reinforcement cannot be achieved in some occasions. Although the other method can achieve the effect of dispersing wind flow and reducing wind resistance, the rain-proof effect of the awning becomes worse. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a canopy with a simple and reliable structure and good wind resistance and rain protection effects.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a canopy comprises a support frame and a ceiling, the ceiling comprises a guide support pipe, a mounting frame and a guide cover plate, a plurality of guide support pipes are provided and are fixedly mounted on the top of the support frame, the plurality of guide support pipes are parallel to each other and are arranged at intervals along the left and right directions, the center lines of the plurality of guide support pipes jointly define a reference plane 1 which is arranged obliquely in the front and rear directions relative to the horizontal plane, and the front end position of the reference plane 1 is lower than the rear end position; the left and right walls of the guide support pipe are oblique outer walls which are arranged oppositely, and the top lateral spacing between the left and right walls of the guide support pipe is smaller than the bottom lateral spacing; the left and right outer walls of the guide support pipe are respectively fixedly provided with guide trough bodies with a top opening, the extension direction of the guide trough bodies is the same as the length direction of the guide support pipe, and the front end of the guide trough bodies is an open structure; the rear side of the mounting frame is hinged to the rear side of the top end of the support frame and there is a A hinge axis line 1 is arranged horizontally and extends along the left-right direction; a plurality of guide covers are provided and are all fixed on the mounting frame, the length direction of the guide cover and the length direction of the guide support tube are both perpendicular to the hinge axis line 1, and the plurality of guide covers are arranged in sequence along the length direction of the hinge axis line 1, and the center lines of the plurality of guide covers in the length direction jointly define a reference plane 2; a guide support tube is arranged between each two adjacent guide covers, and in a natural state, the left and right sides of the lower surface of the guide cover are respectively overlapped on the top of the guide trough body, and the left and right side edges of the guide cover are respectively in contact with the corresponding oblique outer walls or have a preset spacing; the mounting frame is equipped with a travel limiter for controlling the upward rotation stroke of the front side of the mounting frame relative to the front side of the support frame, and when the external force that causes the front side of the mounting frame to rotate upward relative to the front side of the support frame disappears, the mounting frame and the guide cover can rely on their own gravity to return to the natural state.

[0005] It can be known from the above technical scheme that compared with the prior art, the ceiling in the present invention includes a guide support pipe fixed relative to the supporting column and a guide cover plate that can rotate around a hinge axis. In the case of no wind or weak wind, the guide cover plate is in a natural state. Under the action of its own gravity, the left and right sides of the lower surface of the guide cover plate are respectively overlapped on the top of the guide trough body. Most of the rainwater will flow obliquely downward toward the front side of the upper surface of the guide cover plate to the ground, and a small amount of rainwater may pass between the long side of the guide cover plate and the oblique outer wall and flow into the guide trough body. The rainwater in the guide trough body can also flow obliquely downward toward the front side to the ground, thus ensuring the rainproof effect. In the case of strong wind, the wind will blow the front side of the guide cover plate to rotate upward around the hinge axis. At this time, a ventilation gap will be formed between the lower surface of the guide cover and the top wall of the guide trough body, or the ventilation gap will gradually increase. The ventilation gap can effectively disperse the wind flow, reduce wind resistance, weaken the impact of strong winds on the ceiling, and prevent the entire ceiling from being blown over by the wind. The travel limiter can control the guide cover to rotate within a safe travel range. When the wind decreases, the guide cover and the mounting frame can return to their original positions under the action of their own gravity; if it is accompanied by rainfall, even if the wind blows the rain to fall obliquely, the oblique outer wall will effectively block the rain and prevent the rain from passing through the above-mentioned ventilation gap, and the rainwater splashing on the oblique outer wall will flow into the guide trough body; even if the present invention encounters a situation where strong winds and rainfall occur at the same time, the ceiling can effectively disperse the wind flow while playing a rain-proof effect to prevent it from being blown over by the wind.

[0006] In order to make the structure simple and reliable, easier to process and assemble, and at the same time beneficial to the overall rainwater drainage effect, in a preferred solution, under the natural state, reference plane 1 and reference plane 2 are parallel or coplanar with each other.

[0007] In order to make the structure simple and reliable, easier to process and assemble, in the preferred solution, the installation frame is a rectangular frame composed of a transverse beam and a longitudinal beam, the guide cover is fixedly arranged in the inner ring area surrounded by the rectangular frame, the longitudinal center line of the transverse beam and the longitudinal center line of the longitudinal beam jointly define a reference plane three, and the reference plane three is parallel to or coplanar with the reference plane two; the front end face of the guide trough body and the front end face of the guide support pipe are both flush, and the rear end face of the guide trough body and the rear end face of the guide support pipe are both flush, and there is a preset spacing between the front end face of the guide support pipe and the inner ring end wall of the rectangular frame, and between the rear end face of the guide support pipe and the inner ring end wall of the rectangular frame, respectively, and the preset spacing can be comprehensively determined according to the rotation space required when the installation frame rotates around the hinge axis line one and the space size required for the drainage channel in this area. This design can effectively ensure the reliability of the overall rotation structure of the guide cover and the installation frame, and is also conducive to the smooth discharge of rainwater.

[0009] In order to effectively ensure the rain-shielding effect, in the preferred scheme, the stroke limiter can limit the front end of the guide cover plate to the area below the plane where the top side edge of the oblique outer wall of the guide support tube is located. The stroke limit design is conducive to ensuring the rain-shielding effect of the guide cover plate in the extreme position, that is, to ensure that in rainy weather and when encountering strong winds, the obliquely falling rain water will not pass through between adjacent guide support tubes.

[0010] In a preferred embodiment, the support frame includes a support column, a mounting frame, a strut and a positioning bolt. The axis of the support column is arranged vertically, and at least two support columns are provided and are arranged at intervals along the left and right directions. The rear end of the mounting frame is hinged to the upper end of the support column and there is a second hinge axis line between the two, and the second hinge axis line is parallel to the first hinge axis line. Multiple guide support tubes are fixed on the mounting frame; at least two struts are provided, one end of the strut is hinged to the middle part of the mounting frame and the two have a third hinge axis line, and the other end of the strut is provided with a socket, and the third hinge axis line and the hole center line of the socket are both parallel to the second hinge axis line; the support column is provided with a plurality of positioning holes arranged at intervals along its axial direction, and the hole center lines of the positioning holes are parallel to the second hinge axis line, and the socket can be opposite to any one of the positioning holes; the positioning bolts are inserted into the socket and a positioning hole opposite to the socket to connect the strut and the support column. This design can adjust the angle between the reference plane 1 and the horizontal plane, and select the positioning hole at the appropriate height according to the actual situation to match and connect with the jack through the positioning bolt. This design can improve the wind resistance of the canopy, and can also ensure that the rainwater in the diversion trough body and the rainwater on the diversion cover can flow down to the ground quickly and smoothly.

[0011] In order to make the structure simple and reliable and easier to process and assemble, in the preferred solution, the travel limiter is a limit rope, one end of the limit rope is fixedly connected to the front end of the mounting frame, and the other end is fixedly connected to the front end of the mounting frame.

[0013] In a preferred solution, the cross-section of the upper surface of the guide cover is V-shaped, so that the guide cover can more effectively block rain and guide rainwater to flow to the ground.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figures 1 to 9The present invention discloses a canopy, including a support frame and a ceiling, the ceiling including a guide support pipe 2, a mounting frame 3 and a guide cover plate 4, a plurality of guide support pipes 2 are provided and fixedly mounted on the top of the support frame, the plurality of guide support pipes 2 are parallel to each other and arranged at intervals along the left and right directions, the center lines of the plurality of guide support pipes 2 jointly define a reference plane 1 which is arranged obliquely in the front and rear directions relative to the horizontal plane, the front end position of the reference plane 1 is lower than the rear end position; the left side wall and the right side wall of the guide support pipe 2 are oblique outer side walls 20 which are arranged oppositely, the top lateral spacing between the left side wall and the right side wall of the guide support pipe 2 is smaller than the bottom lateral spacing (for the same guide support pipe 2, that is, equivalent to two oblique outer side walls 2 0 in the direction from bottom to top, they are inclined to extend toward each other); the left outer wall and the right outer wall of the guide support pipe 2 are respectively fixedly provided with a guide trough body 21 with a top opening. In order to simplify the device structure, in the preferred solution, the outer side wall of the guide support pipe 2 can be directly used as the trough wall of the guide trough body 21 close to the guide support pipe 2. The extension direction of the guide trough body 21 is the same as the length direction of the guide support pipe 2 (that is, it is equivalent to the axis of the guide trough body 21 being arranged obliquely in the front-to-back direction, and the front end position is lower than the rear end position), and the front end of the guide trough body 21 is an open structure, and the front end opening is mainly used for the drainage of rainwater in the guide trough body 21. There is no mandatory requirement for the rear end of the guide trough body 21, which can be It can be closed or retain the open structure; the rear side of the mounting frame 3 is hinged to the rear side of the top end of the support frame and there is a hinge axis line 1 arranged horizontally and extending in the left-right direction between the two, which is equivalent to the mounting frame 3 as a whole being able to rotate around the hinge axis line 1; there are multiple guide cover plates 4 and they are all fixed on the mounting frame 3, the length direction of the guide cover plates 4 and the length direction of the guide support tube 2 are both perpendicular to the hinge axis line 1, and the multiple guide cover plates 4 are arranged in sequence along the length direction of the hinge axis line 1. The center lines of the multiple guide cover plates 4 in the length direction jointly define a reference plane 2, and the "center line of the guide cover plate 4 in the length direction" refers to the geometric center of its cross section perpendicular to its length direction. Connecting line; a guide support tube 2 is arranged between each two adjacent guide cover plates 4 (that is, the guide cover plates 4 and the guide support tubes 2 are arranged alternately in the left and right directions in sequence). In the natural state, the left and right sides of the lower surface of the guide cover plate 4 are respectively overlapped on the top of the guide slot body 21 (it can be directly overlapped on the top of the slot wall of the guide slot body 21, or it can be overlapped on the oblique outer wall 20, or it can be overlapped on the oblique outer wall 20, which position also corresponds to the limit position of the downward rotation stroke of the installation frame 3), and the left and right side edges of the guide cover plate 4 are respectively in contact with the corresponding oblique outer wall 20 or have a preset spacing (the specific spacing can be determined comprehensively according to the rainproof effect and wind resistance performance);The installation frame 3 is provided with a travel limiter 8 for controlling the upward rotation travel of the front side of the installation frame 3 relative to the front side of the support frame. When the external force causing the front side of the installation frame 3 to rotate upward relative to the front side of the support frame disappears, the installation frame 3 and the guide cover 4 can return to a natural state by their own gravity.

[0029] It is understandable that the limitations on the front, rear, left, right, etc. in the present invention are only for the purpose of facilitating the understanding of the technical solution. The support frame can be implemented in a variety of ways according to different application scenarios, as long as it can meet the overall support strength of the canopy and the top position can provide an installation infrastructure that meets the requirements of the guide support pipe 2 and the installation frame 3.

[0030] The support frame in the present invention can be independently fixed vertically on the ground, that is, the canopy is an independent canopy and is not attached to the building; it can also be fixed on the outer wall of the building, see Fig.10 , the support frame in this embodiment is fixed on the outer wall of the building. When the support frame is fixed on the outer wall of the building, after the ceiling and the support frame are installed, it is usually necessary to install a water channel 9, which is located above the rear area of ​​the installation frame 3. The length direction of the water channel 9 is inclined relative to the horizontal plane in the left-right direction. The hinge position of the installation frame 3 and the support frame is located between the two side walls of the water channel 9. One side wall of the water channel 9 is close to the outside of the building. This design can prevent rainwater from flowing down from the gap between the building and the installation frame 3. Rainwater falling on the outer wall of the building will flow into the water channel 9 and flow to one side of the ceiling; the width and installation height of the water channel 9 are appropriate to ensure that the guide cover plate 4 will not interfere with the water channel 9 when it rotates upward around the hinge axis. In some alternative embodiments, the water channel 9 can also drain water from other positions, for example, diverting water to the upper surface of the ceiling for drainage, or draining water from both sides at the same time, etc. When the support frame is fixed to the inlet and outlet area on the outer wall of the building, the support frame can usually adopt a door-shaped frame structure, that is, it includes support columns 1 located on both sides of the inlet and outlet, and a cross beam located above the inlet and outlet, the axis of the support column 1 is vertically arranged, the cross beam is fixedly connected to the support column 1, and the top area of ​​the cross beam and the support column 1 is then installed with a mounting frame 5 for arranging the guide support pipe 2.

[0031] The ceiling in the present invention includes a guide support tube 2 fixed relative to the support frame and a guide cover plate 4 that can rotate around a hinge axis. In the case of no wind or weak wind, the left and right sides of the lower surface of the guide cover plate 4 are respectively overlapped on the top of the guide trough body 21, and the oblique outer side wall 20 is in close contact with the long side of the guide cover plate 4 or has a small gap. If it is accompanied by rainfall, most of the rainwater will flow obliquely downward to the ground through the upper surface of the guide cover plate 4, and a small amount of rainwater may pass between the long side of the guide cover plate 4 and the oblique outer side wall 20 and flow into the guide trough body 21. The rainwater in the guide trough body 21 can also flow obliquely downward to the ground, that is, to ensure the rainproof effect. In the case of strong wind, the wind will blow The dynamic guide cover plate 4 rotates upward around the hinge axis. At this time, a ventilation gap will be formed or increased between the lower surface of the guide cover plate 4 and the top wall of the guide trough body 21. The ventilation gap is wedge-shaped, which can disperse the wind flow, reduce wind resistance, weaken the impact of strong winds on the ceiling, and prevent the entire ceiling from being blown over by the wind; if it is accompanied by rainfall, even if the wind blows the rain to fall obliquely, the inclined outer wall 20 will effectively block the rain and prevent the rain from passing through the above-mentioned ventilation gap, and the rain splashing on the inclined outer wall 20 will flow into the guide trough body 21; even if the present invention encounters a situation where strong winds and rainfall occur at the same time, the ceiling can not only play a rain-proof effect, but also effectively disperse the wind flow to prevent it from being blown over by the wind. The deflector cover 4 is reliably fixed in the mounting frame 3, and the deflector cover 4 and the mounting frame 3 as a whole can reliably rotate around the hinge axis; the travel limiter 8 can control the rotation of the deflector cover 4 within the safe travel range. When the wind decreases, the deflector cover 4 and the mounting frame 3 can return to their original positions under the action of their own gravity.

[0032] In order to make the structure simple and reliable, easier to process and assemble, and at the same time conducive to the overall rainwater drainage effect, in the preferred scheme, under the natural state, the reference plane 1 and the reference plane 2 are parallel or coplanar to each other, which is equivalent to the drainage direction of the guide trough body 21 and the drainage direction of the guide cover plate 4 being completely different. It can be understood that the drainage surface in the present invention is mainly composed of the guide trough body 21 and the guide cover plate 4. As long as the combination of the two-part drainage structure is ensured to be watertight, the drainage surface between the two does not need to be forced to be completely parallel. For example, when there is strong wind, the wind will blow the guide cover plate 4 to rotate upward around the hinge axis 1, and the drainage surface corresponding to the guide cover plate 4 is adjusted within a certain rotation angle range. In some alternative embodiments, under the natural state, the reference plane 1 and the reference plane 2 may also be non-parallel, and there is a small angle deviation. The specific angle size can be determined comprehensively based on the rainproof effect and wind resistance performance.

[0033] In a preferred embodiment, the installation frame 3 is a rectangular frame composed of a transverse beam and a longitudinal beam, the guide cover plate 4 is fixedly arranged in the inner ring area surrounded by the rectangular frame, the longitudinal center line of the transverse beam and the longitudinal center line of the longitudinal beam jointly define a reference plane 3, and the reference plane 3 is parallel to or coplanar with the reference plane 2; the front end face of the guide trough body 21 is flush with the front end face of the guide support pipe 2, and the rear end face of the guide trough body 21 is flush with the rear end face of the guide support pipe 2. There is a preset spacing between the front end face of the guide support pipe 2 and the inner ring end wall of the rectangular frame, and between the rear end face of the guide support pipe 2 and the inner ring end wall of the rectangular frame. The preset spacing can be comprehensively determined according to the rotation space required when the installation frame 3 rotates around the hinge axis 1 and the space size required for the drainage channel in this area. This design can effectively ensure the reliability of the overall rotation structure of the guide cover plate 4 and the installation frame 3, and is also conducive to the smooth discharge of rainwater. In some alternative embodiments, the mounting frame 3 may also have other structural forms or an irregular shape, as long as the drainage structure formed by the guide trough body 21 and the guide cover plate 4 can meet the rainproof effect, and the mounting frame 3 and the guide cover plate 4 can rotate normally around the hinge axis under strong wind.

[0034] In a preferred embodiment, a plurality of flow-guiding support tubes 2 are evenly spaced and a plurality of flow-guiding cover plates 4 are evenly spaced, so that the force is more balanced and the processing and manufacturing are more convenient.

[0035] In a preferred embodiment, the travel limiter 8 can limit the front end of the guide cover plate 4 to the area below the plane where the top side of the oblique outer wall 20 of the guide support tube 2 is located (with the lower surface of the guide cover plate 4 as the judgment reference), and the plane where the top side of the oblique outer wall 20 of the guide support tube 2 is located refers to the reference plane defined by the top side of the oblique outer wall 20 of all the guide support tubes 2. Since the hinge axis is located in the rear area of ​​the guide cover plate 4, as long as the front end of the guide cover plate 4 does not exceed the top side of the oblique outer wall 20 of the guide support tube 2, the guide cover plate 4 as a whole will not exceed the top side of the oblique outer wall 20 of the guide support tube 2. This travel limiter design is conducive to ensuring the rainproof effect of the guide cover plate 4 at the extreme position, that is, to ensure that in rainy weather and strong winds, obliquely falling rainwater will not pass through between adjacent guide support tubes 2.

[0036] In a preferred embodiment, the support frame includes a support column 1, a mounting frame 5, a strut 6 and a positioning bolt 7. The axis of the support column 1 is arranged vertically, and the support column 1 is provided with at least two and arranged at intervals along the left and right directions. The rear end of the mounting frame 5 is hinged to the upper end of the support column 1 and there is a hinge axis line 2 between the two. The hinge axis line 2 is parallel to the hinge axis line 1. Multiple guide support pipes 2 are fixed on the mounting frame 5; the rear side of the mounting frame 3 can be hinged to the support column 1 or to the mounting frame 5. At least two struts 6 are provided, and one end of the strut 6 is connected to the middle of the mounting frame 5. The two are hinged and have a hinge axis three. The other end of the support rod 6 is provided with a socket 60. The center lines of the hinge axis three and the socket 60 are parallel to the hinge axis two. The support column 1 is provided with a plurality of positioning holes 10 arranged at intervals along its axial direction. The center lines of the positioning holes 10 are parallel to the hinge axis two. The socket 60 can be directly opposite to any one of the positioning holes 10. The positioning bolt 7 is inserted into the socket 60 and a positioning hole 10 directly opposite to the socket 60 to connect the support rod 6 and the support column 1. Any one of the socket 60 and the positioning hole 10 can be a threaded hole. This design can adjust the angle between the reference plane 1 and the horizontal plane. According to the actual situation, the positioning hole 10 at a suitable height position is selected to match and connect with the socket 60 through the positioning bolt 7. This design can improve the wind resistance of the canopy, and can also ensure that the rainwater in the guide trough body 21 and the rainwater on the guide cover plate 4 can flow down to the ground quickly and smoothly.

[0037] The stroke limiter 8 is preferably a limit rope, one end of which is fixedly connected to the front end of the mounting frame 3, and the other end of which is fixedly connected to the front end of the mounting frame 5. It is understandable that the stroke limiter 8 has a variety of alternative embodiments, and a limit protrusion, a limit block and other structural members can be added to the rotation mating surface where the hinge axis 1 is located, and various limit blocks, limit protrusions and the like can also be added to the front end of the mounting frame 3 and the front end of the mounting frame 5. In order to improve the structural reliability, a shock absorbing structure can be added according to different implementation methods of the stroke limiter 8. For example, the limit rope in the present invention is mainly used to limit the upward rotation stroke of the mounting frame 3. The limit rope in this application is a flexible connection, and generally, no additional shock absorbing structure is considered. The downward rotation stroke of the mounting frame 3 is limited by the top position of the guide groove body 21. The top position of the guide groove body 21 is a rigid structure, so it is generally necessary to add a rubber pad or a spring as a shock absorbing structure.

[0038] In a preferred embodiment, a plurality of through holes 22 are provided on the oblique outer side wall 20 of the guide support tube 2, and the plurality of through holes 22 are arranged at intervals along the length direction of the guide support tube 2. The inner cavity side of the guide trough body 21 is connected to the inner cavity of the guide support tube 2 through the through holes 22. The front end of the guide support tube 2 is an open structure, and the rear end of the guide support tube 2 has no mandatory requirements and can be closed or retain an open structure. When there is too much rainwater in the guide trough body 21, the rainwater in the guide trough body 21 can flow into the guide support tube 2 and be discharged from the front end of the guide support tube 2, thereby preventing the rainwater from overflowing from the top wall of the side of the guide trough body 21 to affect the rainproof effect.

[0039] In a preferred embodiment, the cross section of the upper surface of the guide cover plate 4 is V-shaped, so that the guide cover plate 4 can more effectively block rain and guide rainwater to flow down to the ground, reduce the drainage of the guide trough body 21, and prevent rainwater from overflowing from the top wall of the side of the guide trough body 21 to affect the rain blocking effect. The guide cover plate 4 with this cross-sectional shape can also play a role in guiding wind, that is, wind can more easily pass through the air-permeable gap formed between the lower surface of the guide cover plate 4 and the top wall of the guide trough body 21.

[0040] In a preferred embodiment, the lower surface of the deflector cover 4 is integrally formed with a plurality of strip-shaped protrusions 40 and a plurality of strip-shaped protrusions 41. The extension direction of the strip-shaped protrusion 40 is consistent with the length direction of the deflector cover 4, and the extension direction of the strip-shaped protrusion 41 is perpendicular to the length direction of the deflector cover 4. In this way, the deflector cover 4 is not easily deformed, thereby ensuring the structural reliability under strong wind conditions.

[0041] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0042] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention.
