Description

Technical Field

[0001] The present application relates to the technical field of door and window structures, and in particular to a retractable screen window housing. Background Art

[0002] The retractable screen is a common window accessory for mosquito prevention, dust prevention and ventilation in modern homes. Its feature is that the screen can be automatically rolled back into the container inside the window frame, pulled down when in use, and retracted when not in use, without taking up extra space.

[0003] The outer shell of the roll-up screen window (i.e. the window frame) is usually tightly combined with the outer frame of the window to provide a stable installation foundation. One side of the outer shell of the roll-up screen window (usually the top side or any side side) is a screen box, and the screen box is installed with a winding drum for releasing the screen or winding up the recovered screen. In order to reserve sufficient installation space for the winding drum and the wound screen, the thickness of the screen box is greater than the thickness of the other sides of the outer shell of the roll-up screen window, resulting in the overall size of the roll-up screen window outer shell being inconsistent, and the protruding part of the roll-up screen window outer shell (i.e. the screen box) is more susceptible to scratches or collisions than other parts of the roll-up screen window outer shell, resulting in a shorter service life of the protruding part of the roll-up screen window outer shell. Utility Model Content

[0004] The purpose of the present application is to provide a rewinding screen window housing with coordinated dimensions and a longer service life in order to improve the above problems.

[0005] This application is achieved through the following technical solutions:

[0006] In some embodiments, the present application provides a retractable screen window housing, which includes a first beam, a second beam and two third beams connected end to end, the first beam and the second beam are arranged opposite to each other along a first direction, the two third beams are arranged opposite to each other along a second direction, and the first direction is perpendicular to the second direction; the first beam has a cavity for installing a winding drum, the second beam has a positioning groove for the entry and exit of the screen, and the third beam has a sliding groove for the passage of the screen; the surface of the first beam facing the room, the surface of the second beam facing the room and the surface of the third beam facing the room are flush with each other; the surface of the first beam facing the outside of the room, the surface of the second beam facing the outside of the room and the surface of the third beam facing the outside of the room are flush with each other.

[0007] In the technical solution of the embodiment of the present application, the first beam has a cavity for installing a yarn winding cylinder, the second beam has a positioning groove for the screen mesh to enter and exit, the screen mesh has a fixed end and a movable end, the fixed end of the screen mesh is fixedly connected to the yarn winding cylinder, the movable end of the screen mesh is connected with a positioning edge, when the screen mesh is fully unfolded, the positioning edge of the screen mesh is inserted into the positioning groove and engaged with the positioning groove to keep the screen mesh in the unfolded state; the third beam has a chute for the screen mesh to pass through, during the unfolding and winding of the screen mesh, the screen mesh and the positioning edge move along the chute to reduce the risk of the screen mesh moving in a direction deviating from the internal opening of the retractable screen window housing towards the retracting direction; the surfaces of the first beam facing the interior, the second beam facing the interior and the third beam facing the interior are flush with each other in pairs; the surfaces of the first beam facing the exterior, the second beam facing the exterior and the third beam facing the exterior are flush with each other in pairs, so that the dimensions of the first beam, the second beam and the third beam in the third direction are equal, making the overall dimensions of the retractable screen window housing provided by the present application coordinated and consistent, enhancing the integrity of the retractable screen window housing, and making the retractable screen window housing provided by the present application have higher strength; and different from the existing retractable screen window, the scratches or collisions on the existing retractable screen window are likely to concentrate on the protruding part of the retractable screen window housing for installing the yarn winding cylinder, resulting in a shorter service life of this part. The surfaces of the retractable screen window housing provided by the present application facing the interior side and the interior side are both smooth planes. When the retractable screen window housing provided by the present application is scratched or collided, the damage will be irregularly distributed everywhere on the retractable screen window housing provided by the present application, reducing the risk of premature damage to the first beam (equivalent to the screen mesh box in the existing retractable screen window housing) for installing the yarn winding cylinder, thereby enhancing the service life of the first beam for installing the yarn winding cylinder.

[0008] In some embodiments, the first beam includes a first frame and a second frame. The first frame includes a first side and a second side that are perpendicular to each other, and the second frame includes a third side and a fourth side that are perpendicular to each other. The first side, the second side, the third side and the fourth side enclose a cavity for installing a yarn winding cylinder. The first side and the third side are arranged opposite to each other in the first direction, and the second side and the fourth side are arranged opposite to each other in the third direction. The first direction, the second direction and the third direction are perpendicular to each other in pairs; the second side is rotatably connected to the third side, and the first frame rotates about the second direction as the axis. In the third direction, there is a gap between the first side and the fourth side to form an opening facing the second beam and for the screen mesh to pass through.

[0009] In the technical solution of the embodiment of the present application, the first frame includes a first side and a second side that are perpendicular to each other, and the second frame includes a third side and a fourth side that are perpendicular to each other. The first side, the second side, the third side, and the fourth side enclose a cavity for installing a yarn winding cylinder. The yarn winding cylinder is rotatably arranged in the cavity. The first side and the third side are arranged opposite to each other in the first direction, and the second side and the fourth side are arranged opposite to each other in the third direction. The second side is rotatably connected to the third side, and the first frame rotates around the second direction as the axis. In the third direction, there is a gap between the first side and the fourth side to form an opening for the screen mesh to pass through and face the second beam. The first frame can rotate around the third side to expand the opening for the screen mesh to pass through between the first side and the fourth side, facilitating the user to extend a cleaning tool between the first frame and the second frame to clean the yarn winding cylinder. The user can scrub the inner side of the screen mesh wound around the yarn winding cylinder while unfolding the screen mesh, and scrub the outer side of the screen mesh continuously wound around the yarn winding cylinder when winding up the screen mesh, eliminating the trouble of disassembling a part of the structure of the existing retractable screen window housing for installing the yarn winding cylinder to scrub the yarn winding cylinder and a part of the screen mesh close to the yarn winding cylinder. The operation is simple and convenient to use.

[0010] In some embodiments, a rotating shaft is fixedly arranged on the third side, the axial direction of the rotating shaft is parallel to the second direction, a rotating member is fixedly arranged on the second side, and the rotating member is rotatably sleeved on the rotating shaft.

[0011] In the technical solution of the embodiment of the present application, a rotating shaft is fixedly arranged on the third side, a rotating member is fixedly arranged on the second side, the rotating member is rotatably sleeved on the rotating shaft, the inner wall of the rotating member is in contact with the outer peripheral surface of the rotating shaft, and the contact area between the two is large, enabling the rotating shaft to limit the rotation direction of the rotating member and reducing the risk of the axial deviation of the rotating member from the second direction during rotation. The connection between the rotating member and the rotating shaft is stable, the structure is simple, and the difficulty of maintenance and disassembly is low.

[0012] In some embodiments, an avoidance groove is arranged on the outer peripheral surface of the rotating shaft, and a first convex portion is arranged on the inner surface of the rotating member. The first frame has an open state and a closed state. When the first frame is in the open state, the first convex portion extends into the avoidance groove, and the first frame rotates away from the second frame around the second direction as the axis. When the first frame is in the closed state, the first convex portion presses against the outer peripheral surface of the rotating shaft, the first side is opposite to the third side, and the second side is opposite to the fourth side.

[0013] In the technical solution of the embodiment of the present application, the first frame has an open state and a closed state. When the first frame is in the open state, the first protrusion extends into the avoidance groove, and the first frame rotates away from the second frame with the second direction as the axis, so that the opening between the first side and the fourth side is widened to facilitate the user to scrub the screen and the yarn winding cylinder; when the first frame is in the closed state, the first side is opposite to the third side, the second side is opposite to the fourth side, and the first protrusion presses against the outer peripheral surface of the rotating shaft, so that the first frame cannot rotate relative to the second frame by itself, and the opening for the screen to pass through between the first side and the fourth side can be close to the screen to limit it.

[0014] In some embodiments, a set of connection components are provided at each of the two opposite ends of the first beam along the second direction. The connection components include an end cap and a positioning member. The end cap is used to close the opening at the end of the first beam, and the end cap is connected to the third beam. The positioning member is located between the end cap and the first beam, and the positioning member is fixedly connected to the end cap; the positioning member is used to connect the yarn winding cylinder, and the positioning member is provided with a first hole coaxial with the yarn winding cylinder, and the end cap is provided with a second hole coaxial with the first hole.

[0015] In the technical solution of the embodiment of the present application, the connection components include an end cap and a positioning member. The end cap is used to close the opening at the end of the first beam, and the end cap is connected to the third beam. The first beam is connected to the third beam through the end cap, reducing the risk of damaging the overall strength of the first beam by opening through holes in the first beam, and the positioning member is fixedly connected to the end cap; the positioning member is used to connect the yarn winding cylinder, and the positioning member enables the yarn winding cylinder to be in the center of the inner cavity of the first beam, reserving enough space for the screen on the yarn winding cylinder. The positioning member is provided with a first hole coaxial with the yarn winding cylinder, and the end cap is provided with a second hole coaxial with the first hole. The user can insert tools such as a screwdriver through the first hole and the second hole into the cavity inside the first beam to rotate the yarn winding cylinder to adjust the tightness of the unfolded screen, so that the screen can adapt to various usage environments.

[0016] In some embodiments, one end of the third beam facing the first beam in the first direction is stepped, and the end cap fits and adheres to the third beam.

[0017] In the technical solution of the embodiment of the present application, one end of the third beam facing the first beam in the first direction is stepped. By making the surface tortuous, one end of the third beam facing the first beam has a larger surface area. The end cap fits and adheres to the third beam. Since the contact area between the third beam and the end cap is large, the adhesion effect between the end cap and the third beam is relatively stable and the connection strength is high.

[0018] In some embodiments, the end cap is connected to the third beam by screws, and the positioning member is connected to the end cap by screws.

[0019] In the technical solution of the embodiment of the present application, the end cover is connected to the third beam by screws. The screws connecting the third beam and the end cover extend in the first direction. The positioning member is connected to the end cover by screws. The screws connecting the positioning member and the end cover extend in the second direction. The connection by screws has a simple structure, high connection strength and stable connection effect.

[0020] In some embodiments, a part of the positioning member extends into the third beam, and a second protrusion is further provided on the part of the positioning member extending into the third beam. The second protrusion abuts against the inner wall of the third beam.

[0021] In the technical solution of the embodiment of the present application, a part of the positioning member extends into the third beam. A part of the positioning member can extend into the third beam prior to the end cover to preliminarily determine the relative position between the third beam and the first beam. Then, the end cover is brought into contact with and connected to the third beam, reducing the probability of misalignment between the third beam and the end cover. A second protrusion is further provided on the part of the positioning member extending into the third beam. The second protrusion abuts against the inner wall of the third beam, so that the position of the two can be limited after a part of the positioning member extends into the third beam, reducing the risk of displacement of the third beam relative to the end cover during the subsequent connection of the end cover and the third beam.

[0022] In some embodiments, one end of the third beam facing the second beam in the first direction is stepped, and the second beam is attached to and adhesively bonded to the third beam.

[0023] In the technical solution of the embodiment of the present application, one end of the third beam facing the second beam in the first direction is stepped. By making the surface tortuous, the end of the third beam facing the second beam has a larger surface area. The second beam is attached to and adhesively bonded to the third beam. Since the contact area between the third beam and the second beam is large, the adhesion effect between the second beam and the third beam is relatively stable and the connection strength is high.

[0024] In some embodiments, the second beam is connected to the third beam by screws.

[0025] In the technical solution of the embodiment of the present application, the second beam is connected to the third beam by screws. The screws connecting the second beam and the third beam extend in the first direction. The connection by screws has a simple structure, high connection strength and stable connection effect.

[0041] According to some embodiments of this application, optionally, such as Figures 1 to 2 and Figure 6As shown, the present application provides a rewinding screen window housing 1, which includes a first beam 10, a second beam 11 and two third beams 12 connected end to end, the first beam 10 and the second beam 11 are relatively arranged along a first direction X, and the two third beams 12 are relatively arranged along a second direction Y, and the first direction X is perpendicular to the second direction Y; the first beam 10 has a cavity for installing a yarn drum 3, the second beam 11 has a positioning groove for the entry and exit of a gauze net 2, and the third beam 12 has a slide groove for the gauze net 2 to pass through; the surface of the first beam 10 facing the room, the surface of the second beam 11 facing the room and the surface of the third beam 12 facing the room are flush with each other; the surface of the first beam 10 facing the outside of the room, the surface of the second beam 11 facing the outside of the room and the surface of the third beam 12 facing the outside of the room are flush with each other.

[0042] The top mentioned in the present application is the side of the rewinding screen window facing away from the ground, and the bottom mentioned in the present application is the side of the rewinding screen window close to the ground or the work platform.

[0043] The indoor side mentioned in the present application means the inner side of the building where the rewinding screen is installed; the outdoor side mentioned in the present application means the outer side of the building where the rewinding screen is installed.

[0044] In addition to the rewinding screen window housing 1 provided in the present application, the rewinding screen window also includes a screen 2, a spring device, a guide wheel and a yarn reel 3. The yarn reel 3 rotates to wind the screen 2 around itself or release the screen 2. The spring device is usually located at the upper edge of the screen 2 and is connected to the rewinding screen window housing 1 through a torsion spring curtain mechanism to control the reeling and unfolding of the screen 2. The guide wheel is located at the lower edge of the screen 2 and is connected to the yarn reel 3 to ensure that the screen 2 can move smoothly when reeling. When the screen window needs to be opened, the user gently pulls the screen 2, which will cause the spring device to twist. When the screen 2 is fully opened, the spring device remains in a relaxed state. When the screen window is retracted, just push the screen 2 gently, the spring device will tighten the screen 2, make it reel back to the yarn reel 3, and restore it to its original state when the screen 2 is fully reeled, ready for the next opening.

[0045] The retractable screen window housing 1 provided in the present application is fastened to the wall through the outer frame 3 .

[0046] The X direction shown in the figure is a first direction.

[0047] The Y direction shown in the figure is the second direction.

[0048] The Z direction shown in the figure is the third direction.

[0049] The first beam 10 has a cavity for mounting the yarn reel 3, the second beam 11 has a positioning groove for the screen 2 to enter and exit, the screen 2 has a fixed end and a movable end, the fixed end of the screen 2 is fixedly connected to the yarn reel 3, the movable end of the screen 2 is connected with a positioning edge. When the screen 2 is fully extended, the positioning edge of the screen 2 is inserted into the positioning groove and engaged with the positioning groove to keep the screen 2 in the extended state; the third beam 12 has a sliding groove for the screen 2 to pass through. During the process of the screen 2 being extended and retracted, the screen 2 and the positioning edge move along the sliding groove to reduce the risk of the screen 2 moving in a direction deviating from the internal opening of the retractable screen window housing 1; the surfaces of the first beam 10 facing the interior, the second beam 11 facing the interior and the third beam 12 facing the interior are flush with each other in pairs; the surfaces of the first beam 10 facing the exterior, the second beam 11 facing the exterior and the third beam 12 facing the exterior are flush with each other in pairs, so that the dimensions of the first beam 10, the second beam 11 and the third beam 12 in the third direction Z are equal, making the overall dimensions of the retractable screen window housing 1 provided by this application coordinated and consistent, enhancing the integrity of the retractable screen window housing 1, and making the retractable screen window housing 1 provided by this application have higher strength; and different from the existing retractable screen windows, the scratches or collisions on the existing retractable screen windows are easily concentrated on the protruding part of the retractable screen window housing 1 where the yarn reel 3 is installed, resulting in a shorter service life of this part. The surfaces of the retractable screen window housing 1 provided by this application facing the interior side and the interior side are both smooth planes. When the retractable screen window housing 1 provided by this application is scratched or collided, the damage will be irregularly distributed everywhere on the retractable screen window housing 1 provided by this application, reducing the risk of premature damage to the first beam 10 for mounting the yarn reel 3, thereby enhancing the service life of the first beam 10 (equivalent to the screen 2 box in the existing retractable screen window housing 1) for mounting the yarn reel 3.

[0050] According to some embodiments of the present application, optionally, as Figures 3 to 5 shown, the first beam 10 includes a first frame 100 and a second frame 101. The first frame 100 includes a first side 1000 and a second side 1001 that are perpendicular to each other. The second frame 101 includes a third side 1010 and a fourth side 1011 that are perpendicular to each other. The first side 1000, the second side 1001, the third side 1010 and the fourth side 1011 enclose a cavity for mounting the yarn reel 3. The first side 1000 and the third side 1010 are arranged opposite to each other in the first direction X, and the second side 1001 and the fourth side 1011 are arranged opposite to each other in the third direction Z. The first direction X, the second direction Y and the third direction Z are perpendicular to each other in pairs; the second side 1001 is rotatably connected to the third side 1010, and the first frame 100 rotates about the second direction Y as the axis. In the third direction Z, there is a gap between the first side 1000 and the fourth side 1011 to form an opening facing the second beam 11 and for the screen 2 to pass through.

[0051] The fourth side 1011 is further provided with a third protrusion extending towards the first side 1000 along the third direction Z. The size and position of the opening for the screen 2 to pass through between the first side 1000 and the fourth side 1011 are controlled by the size of the third protrusion in the third direction Z, so as to adapt to the installation requirements of the screen 2 in different unfolded positions in various usage environments.

[0052] The first frame 100 includes a first side 1000 and a second side 1001 that are perpendicular to each other. The second frame 101 includes a third side 1010 and a fourth side 1011 that are perpendicular to each other. The first side 1000, the second side 1001, the third side 1010, and the fourth side 1011 enclose a cavity for installing the winding cylinder 3. The winding cylinder 3 is rotatably arranged in the cavity. The first side 1000 and the third side 1010 are arranged opposite to each other along the first direction X, and the second side 1001 and the fourth side 1011 are arranged opposite to each other along the third direction Z. The second side 1001 is rotatably connected to the third side 1010, and the first frame 100 rotates about the second direction Y as the axis. In the third direction Z, there is a gap between the first side 1000 and the fourth side 1011 to form an opening facing the second beam 11 and for the screen 2 to pass through. The first frame 100 can rotate around the third side 1010 to expand the opening for the screen 2 to pass through between the first side 1000 and the fourth side 1011, facilitating the user to extend the cleaning tool between the first frame 100 and the second frame 101 to clean the winding cylinder 3. The user can scrub the inner side of the screen 2 wound around the winding cylinder 3 while unfolding the screen 2, and scrub the outer side of the screen 2 continuously wound around the winding cylinder 3 when winding up the screen 2, eliminating the trouble of disassembling a part of the structure of the existing retractable screen window housing 1 for installing the winding cylinder 3 to scrub the winding cylinder 3 and a part of the screen 2 close to the winding cylinder 3. The operation is simple and convenient to use.

[0053] According to some embodiments of the present application, optionally, as Figures 3 to 5 shown, a rotating shaft 1012 is fixedly arranged on the third side 1010. The axial direction of the rotating shaft 1012 is parallel to the second direction Y. A rotating member 1002 is fixedly arranged on the second side 1001. The rotating member 1002 is rotatably sleeved on the rotating shaft 1012.

[0054] The rotating member 1002 can be an incomplete cylinder. The opening on the rotating member 1002 is used to avoid the connection between the rotating shaft 1012 and the third side 1010.

[0055] The third side 1010 is fixedly provided with a rotating shaft 1012, and the second side 1001 is fixedly provided with a rotating member 1002. The rotating member 1002 is rotatably sleeved on the rotating shaft 1012. The inner wall of the rotating member 1002 fits with the outer peripheral surface of the rotating shaft 1012, and the contact area between the two is relatively large, enabling the rotating shaft 1012 to limit the rotation direction of the rotating member 1002 and reducing the risk of the axial deviation of the rotating member 1002 from the second direction Y during rotation. The connection between the rotating member 1002 and the rotating shaft 1012 is stable, the structure is simple, and the difficulty of maintenance, disassembly and assembly is relatively low.

[0056] According to some embodiments of the present application, optionally, as Figures 3 to 5 shown, an avoidance groove is provided on the outer peripheral surface of the rotating shaft 1012, and a first protrusion is provided on the inner surface of the rotating member 1002. The first frame 100 has an open state and a closed state. When the first frame 100 is in the open state, the first protrusion extends into the avoidance groove, and the first frame 100 rotates away from the second frame 101 with the second direction Y as the axis; when the first frame 100 is in the closed state, the first protrusion presses against the outer peripheral surface of the rotating shaft 1012, the first side 1000 is opposite to the third side 1010, and the second side 1001 is opposite to the fourth side 1011.

[0057] When the first frame 100 is in the closed state, the third side 1010 contacts the rotating member 1002 to limit the further rotation of the first frame 100 towards the second frame 101;

[0058] When the first frame 100 is in the open state, the outer frame 3 contacts the second side 1001 to limit the further rotation of the second frame 101 away from the second frame 101.

[0059] The first frame 100 has an open state and a closed state. When the first frame 100 is in the open state, the first protrusion extends into the avoidance groove, and the first frame 100 rotates away from the second frame 101 with the second direction Y as the axis, so that the opening between the first side 1000 and the fourth side 1011 is widened to facilitate the user to scrub the screen 2 and the winding cylinder 3.

[0060] When the first frame 100 is in the closed state, the first side 1000 is opposite to the third side 1010, the second side 1001 is opposite to the fourth side 1011, and the first protrusion presses against the outer peripheral surface of the rotating shaft 1012, so that the first frame 100 cannot rotate relative to the second frame 101 by itself, and the opening for the screen 2 to pass through between the first side 1000 and the fourth side 1011 can be close to the screen 2 to limit it.

[0061] According to some embodiments of the present application, optionally, as Figure 3As shown, a set of connection components 13 are provided at each of the two opposite ends of the first beam 10 along the second direction Y. The connection components 13 include an end cap 130 and a positioning member 131. The end cap 130 is used to close the opening at the end of the first beam 10, and the end cap 130 is connected to the third beam 12. The positioning member 131 is located between the end cap 130 and the first beam 10, and the positioning member 131 is fixedly connected to the end cap 130. The positioning member 131 is used to connect the yarn reel 3. The positioning member 131 is provided with a first hole 1310 coaxial with the yarn reel 3, and the end cap 130 is provided with a second hole 1300 coaxial with the first hole 1310.

[0062] The end cap 130 can be detachably connected to the third beam 12.

[0063] The positioning member 131 can be in contact with the first frame 100 and the second frame 101 in the closed state. When the yarn reel 3 unfolds or winds up the yarn net 2 relatively quickly, the vibration of the positioning member 131 from the yarn reel 3 is restricted by the first frame 100 and the second frame 101, thereby reducing the vibration amplitude of the positioning member 131 and reducing the risk of damage to both due to the collision of the positioning member 131 with components such as the end cap 130 caused by vibration.

[0064] The connection components 13 include an end cap 130 and a positioning member 131. The end cap 130 is used to close the opening at the end of the first beam 10, and the end cap 130 is connected to the third beam 12. The first beam 10 is connected to the third beam 12 through the end cap 130, reducing the risk of damaging the overall strength of the first beam 10 by opening through holes in the first beam 10, and the positioning member 131 is fixedly connected to the end cap 130. The positioning member 131 is used to connect the yarn reel 3. The positioning member 131 enables the yarn reel 3 to be centered in the inner cavity of the first beam 10, reserving enough space for the yarn net 2 on the yarn reel 3. The positioning member 131 is provided with a first hole 1310 coaxial with the yarn reel 3, and the end cap 130 is provided with a second hole 1300 coaxial with the first hole 1310. Users can insert tools such as screwdrivers into the inner cavity of the first beam 10 through the first hole 1310 and the second hole 1300 to rotate the yarn reel 3 to adjust the tightness of the unfolded yarn net 2, so that the yarn net 2 can adapt to diverse usage environments.

[0065] According to some embodiments of the present application, optionally, as Figure 3 shown, one end of the third beam 12 facing the first beam 10 in the first direction X is stepped, and the end cap 130 is fitted and adhesively bonded to the third beam 12.

[0066] The end cap 130 and the third beam 12 can be adhered through double-sided tape or liquid glue.

[0067] The third beam 12 is stepped at one end towards the first beam 10 in the first direction X. By making the surface tortuous, the end of the third beam 12 towards the first beam 10 has a larger surface area. The end cap 130 fits and adheres to the third beam 12. Since the contact area between the third beam 12 and the end cap 130 is large, the adhesion effect between the end cap 130 and the third beam 12 is relatively stable, and the connection strength is high.

[0068] According to some embodiments of the present application, optionally, as Figure 3 shown, the end cap 130 is connected to the third beam 12 by screws, and the positioning member 131 is connected to the end cap 130 by screws.

[0069] The end cap 130 is connected to the third beam 12 by screws. The screws connecting the third beam 12 and the end cap 130 extend in the first direction X. The positioning member 131 is connected to the end cap 130 by screws. The screws connecting the positioning member 131 and the end cap 130 extend in the second direction Y. The connection by screws has a simple structure, high connection strength, and stable connection effect.

[0070] According to some embodiments of the present application, optionally, as Figure 3 shown, a part of the positioning member 131 extends into the third beam 12, and a second convex portion 1311 is further provided on the part of the positioning member 131 extending into the third beam 12. The second convex portion 1311 abuts against the inner wall of the third beam 12.

[0071] The third beam 12 can be a profile with a cavity inside.

[0072] The second convex portion 1311 can have elasticity.

[0073] The second convex portion 1311 can have a slope surface, and the height gradually rises from the end of the second convex portion 1311 close to the third beam 12 to the end of the second convex portion 1311 away from the third beam 12.

[0074] A part of the positioning member 131 extends into the third beam 12. A part of the positioning member 131 can extend into the third beam 12 prior to the end cap 130 to preliminarily determine the relative position between the third beam 12 and the first beam 10. Then, the end cap 130 is brought into contact with and connected to the third beam 12 to reduce the probability of misalignment between the third beam 12 and the end cap 130. Moreover, a second convex portion 1311 is further provided on the part of the positioning member 131 extending into the third beam 12. The second convex portion 1311 abuts against the inner wall of the third beam 12. After a part of the positioning member 131 extends into the third beam 12, the positions of the two can be limited, reducing the risk of displacement of the third beam 12 relative to the end cap 130 during the subsequent connection of the end cap 130 and the third beam 12.

[0075] According to some embodiments of the present application, optionally, as Figure 3As shown, one end of the third beam 12 facing the second beam 11 in the first direction X is stepped, and the second beam 11 is attached to and adhesively bonded to the third beam 12.

[0076] The second beam 11 and the third beam 12 can be adhered by double-sided tape or liquid glue.

[0077] One end of the third beam 12 facing the second beam 11 in the first direction X is stepped. By making the surface tortuous, one end of the third beam 12 facing the second beam 11 has a larger surface area. The second beam 11 is attached to and adhesively bonded to the third beam 12. Since the contact area between the third beam 12 and the second beam 11 is large, the adhesion effect between the second beam 11 and the third beam 12 is relatively stable and the connection strength is high.

[0078] According to some embodiments of the present application, optionally, as Figure 3 shown, the second beam 11 is connected to the third beam 12 by screws.

[0079] The second beam 11 is connected to the third beam 12 by screws. The screws connecting the second beam 11 and the third beam 12 extend in the first direction X. The connection by screws has a simple structure, high connection strength and stable connection effect.
