Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, specifically a guide rail locking structure for a magnetically controlled insulated glass curtain wall. Background Technology

[0002] Magnetic-controlled insulated glass curtain walls are widely used in the architectural decoration field because they integrate the dual advantages of "insulated glass heat and sound insulation" and "built-in louvered sunshade adjustment". Their core principle is that the magnetic handle on the outside of the glass connects to the inner magnet assembly, which in turn magnetically attracts the magnets built into the controller within the louvers. This magnetic attraction causes the controller to rise and fall, thus controlling the opening and closing of the louvers. During louver inspection, the operator holds a controller that is attracted to the controller built into the louvers to open and close the louvers.

[0003] Based on the above, the inventors have discovered the following problems: When the magnetic control handle of the current insulated glass curtain wall is slidable, it is easy to shift laterally or tilt, which causes the relative position of the handle to be misaligned with the inner magnet assembly. This results in a sudden drop in magnetic attraction strength or even failure, leading to demagnetization, interruption of operation, and inability to adjust the louver angle.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a guide rail locking structure for a magnetically controlled insulated glass curtain wall, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a guide rail locking structure for a magnetically controlled insulated glass curtain wall to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A guide rail locking structure for a magnetically controlled insulated glass curtain wall includes an inner magnet assembly, a magnetic control handle, a guide rail assembly, and a locking assembly. The inner magnet assembly is disposed within the inner cavity of the insulated glass. The magnetic control handle is disposed on the outer side of the insulated glass and opposite to the inner magnet assembly. The guide rail assembly is disposed on one side of the magnetic control handle. The locking assembly is disposed on the magnetic control handle. The guide rail assembly is used to constrain the sliding path of the magnetic control handle, and the locking assembly is used to provide braking conditions to prevent the movement of the magnetic control handle. The guide rail assembly includes a tail rail, with an inner rib installed inside the tail rail. A serrated retaining strip is installed inside the inner rib, and several slots are formed on the serrated retaining strip. A sliding groove is formed on one side of the tail rail, and a pair of T-shaped sliding strips are slidably connected inside the sliding groove. The pair of T-shaped sliding strips are fixedly connected to the outer wall of the magnetic control handle at the end away from the serrated strip.

[0008] Furthermore, the magnetic control handle has an opening between a pair of T-shaped slide bars. The locking assembly includes a rotating shaft located inside the magnetic control handle. Both ends of the rotating shaft are rotatably connected to the inner wall of the magnetic control handle. A stop bar is fitted on the outside of the rotating shaft. One end of the stop bar abuts against one of the slots of the serrated locking bar through the opening. One end of the stop bar is inclined.

[0009] The beneficial effect of adopting the above-mentioned further solution is that when the stop bar is in the locked state, one end of the stop bar abuts against the slot, making it impossible for the magnetic control handle to slide up or down under the cooperation of the stop bar and the serrated slot; when the stop bar is in the unlocked state, one end of the stop bar no longer abuts against the slot, and at this time, the inner magnet assembly can be moved up or down by pulling up or pushing down the magnetic control handle; rotating the stop bar clockwise, one end of the stop bar is located in the slot of the adjacent serrated slot, which is the locked state; rotating the stop bar counterclockwise, one end of the stop bar is no longer located in the slot of the adjacent serrated slot, which is the unlocked state.

[0010] Furthermore, the locking assembly also includes a mounting box, which is installed at the bottom of the magnetic control handle. The bottom end of the rotating shaft extends through the mounting box into the interior. A ratchet is installed at the bottom end of the rotating shaft. A connecting shaft is fixedly installed inside the mounting box on the side near the rotating shaft. A pawl is fitted on the upper end of the connecting shaft. The ratchet and the pawl engage with each other.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of ratchet and pawl, the ratchet and pawl are linked with the rotating shaft. When the stop bar is locked in the slot, the ratchet is engaged by the pawl in one direction. The double locking structure can withstand greater external force. Even if the stop bar is temporarily disengaged from the slot due to extreme vibration, the ratchet and pawl can still lock the rotating shaft to prevent the magnetic control handle from sliding and demagnetizing. When unlocking is required, only by pressing the pawl can the pawl and ratchet be disengaged. At this time, the rotating shaft can be rotated counterclockwise to separate the stop bar from the serrated pawl slot.

[0012] Furthermore, a spring is installed on the inner wall of the mounting box on the side near the pawl, and one end of the spring is fixedly connected to the outer wall of the end of the pawl away from the connecting shaft.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the setting of the spring, the spring provides a continuous preload force to the pawl, ensuring that the pawl is always engaged with the ratchet. Even if the handle is vibrated and the pawl briefly disengages from the ratchet, the spring will quickly push the pawl back to re-engage, avoiding the magnetic control handle from demagnetizing due to the locking failure caused by the pawl loosening.

[0014] Furthermore, both ends of the inner rib are provided with breaks, the longitudinal section of the serrated strip is "T" shaped, the distance between the two breaks is consistent with the length of the serrated strip, and the opposite sides of the two breaks are respectively attached to the two sides of the end of the serrated strip away from the slot.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, due to the stamped breaks at both ends of the inner rib, the snap-fit ​​installation of the breaks at both ends of the inner rib with the T-shaped serrated clip replaces the traditional screw fixing. During production, workers can directly insert the serrated clip into the breaks and use the T-shaped structure for self-locking to improve the installation stability of the serrated clip.

[0016] Furthermore, both the inner rib and the serrated strip are made of aluminum alloy.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting the inner ribs and serrated strips to aluminum alloy, the density of aluminum alloy is less than that of metal steel, which can reduce the weight of the guide rail assembly and reduce the excessive load on the insulated glass curtain wall. At the same time, aluminum alloy has good tensile and compressive strength, which meets the locking requirements.

[0018] Furthermore, the inner magnet assembly and the magnetically controlled handle are magnetically attracted to each other.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The guide rail locking structure of this magnetically controlled hollow glass curtain wall, with its tail rail, has a tail that can be pressed against the bottom of the door and window trim line for better fixation. When the stop bar is in the locked state, one end of the stop bar abuts against the slot, preventing the magnetic control handle from sliding up or down under the cooperation of the stop bar and the serrated slot. At the same time, the ratchet and pawl are linked with the rotating shaft. When the stop bar is locked in the slot, the ratchet is engaged by the pawl in one direction. The double locking structure can withstand greater external force. Even if the stop bar temporarily disengages from the slot due to extreme vibration, the ratchet will still engage. The pawl can still lock the shaft, preventing the magnetic handle from slipping and demagnetizing. When unlocking is required, only by pressing the pawl can the pawl and ratchet be disengaged. At this time, rotating the shaft counterclockwise can separate the stop bar from the serrated locking groove, and the stop bar is in the unlocked state. One end of the stop bar is no longer in contact with the groove. At this time, the magnetic handle can be pulled up or pushed down to move the inner magnet assembly up or down. Rotating the stop bar clockwise will cause one end of the stop bar to be in the groove of the adjacent serrated locking groove, which is the locked state. Rotating the stop bar counterclockwise will cause one end of the stop bar to be no longer in the groove of the adjacent serrated locking groove, which is the unlocked state.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5This utility model provides a technical solution: a guide rail locking structure for a magnetically controlled insulated glass curtain wall, comprising an inner magnet assembly 1, a magnetic control handle 2, a guide rail assembly 3, and a locking assembly 4. The inner magnet assembly 1 is disposed within the inner cavity of the insulated glass, the magnetic control handle 2 is disposed on the outer side of the insulated glass and opposite to the inner magnet assembly 1, the guide rail assembly 3 is disposed on one side of the magnetic control handle 2, and the locking assembly 4 is disposed on the magnetic control handle 2. The guide rail assembly 3 is used to constrain the sliding path of the magnetic control handle 2, and the locking assembly 4 is used to provide braking conditions to prevent the movement of the magnetic control handle 2. Component 3 includes a tail rail 31, with an inner rib 32 installed inside the tail rail 31. A serrated retaining strip 35 is installed inside the inner rib 32. Several slots 36 are provided on the serrated retaining strip 35. A sliding groove is provided on one side of the tail rail 31. A pair of T-shaped sliders 34 are slidably connected inside the sliding groove. The pair of T-shaped sliders 34 are fixedly connected to the outer wall of the magnetic control handle 2 at the end away from the rack. Through the cooperation of the sliding groove and the T-shaped sliders 34, the sliding path of the magnetic control handle 2 is constrained, allowing the inner magnet assembly 1 to slide up and down along the rail.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-5This utility model provides a technical solution: the magnetic control handle 2 has an opening between a pair of T-shaped slide bars 34. The locking assembly 4 includes a rotating shaft 41, which is disposed inside the magnetic control handle 2. Both ends of the rotating shaft 41 are rotatably connected to the inner wall of the magnetic control handle 2. A stop bar 42 is fitted outside the rotating shaft 41. One end of the stop bar 42 abuts against one of the slots 36 of the serrated locking bar 35 through the opening. The locking assembly 4 also includes a mounting box 43, which is installed at the bottom of the magnetic control handle 2. The bottom end of the rotating shaft 41 is through-mounted. The housing 43 extends inward, and a ratchet 44 is installed at the bottom end of the rotating shaft 41. A connecting shaft 45 is fixedly installed inside the housing 43 on the side near the rotating shaft 41. Pads 46 are fitted onto the upper end of each connecting shaft 45. The ratchet 44 and pawls 46 engage. A spring 47 is installed on the inner wall of the housing 43 on the side near the pawls 46. One end of the spring 47 is fixedly connected to the outer wall of the end of the pawls 46 away from the connecting shaft 45. One end of the stop bar 42 is inclined. When the stop bar 42 is in the locked state, one end of the stop bar 42 abuts against the slot 36. This prevents the magnetic handle 2 from sliding up or down under the cooperation of the stop bar 42 and the serrated slot 36. Simultaneously, the ratchet 44 and pawl 46 are linked to the rotating shaft 41. When the stop bar 42 is locked into the slot 36, the ratchet 44 is engaged unidirectionally by the pawl 46. This double-locking structure can withstand greater external force. Even if the stop bar 42 briefly disengages from the slot 36 due to extreme vibration, the ratchet 44 and pawl 46 can still lock the rotating shaft 41, preventing the magnetic handle 2 from sliding and demagnetizing. When unlocking is required, only by pressing the pawl 46 can the pawl 46 and ratchet 44 be disengaged. Rotating the shaft 41 counterclockwise will separate the stop bar 42 from the slot 36 of the serrated locking bar 35, putting the stop bar 42 in the unlocked state. One end of the stop bar 42 will no longer be in contact with the slot 36. At this time, the inner magnet group 1 can be moved up or down by pulling the magnetic control handle 2 upward or downward. Rotating the stop bar 42 clockwise will put one end of the stop bar 42 into the slot 36 of the adjacent serrated locking bar 35, which is the locked state. Rotating the stop bar 42 counterclockwise will put one end of the stop bar 42 out of the slot 36 of the adjacent serrated locking bar 35, which is the unlocked state.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5This utility model provides a technical solution: both ends of the inner rib 32 are provided with breaks 33, the longitudinal section of the serrated clip 35 is T-shaped, the distance between the two breaks 33 is the same as the length of the serrated clip 35, and the opposite sides of the two breaks 33 are respectively attached to the two sides of the end of the serrated clip 35 away from the slot 36. The inner rib 32 and the serrated clip 35 are both made of aluminum alloy. The inner magnet assembly 1 and the magnetic control handle 2 are magnetically attracted to each other. Due to the stamped breaks 33 at both ends of the inner rib 32, the breaks 33 at both ends of the inner rib 32 and the T-shaped cross section are connected. The snap-fit ​​installation of the serrated clip 35 replaces the traditional screw fixing. During production, workers can directly insert the serrated clip 35 into the break 33. The T-shaped structure self-locks, improving the installation stability of the serrated clip 35. The components and working principle of the inner magnet assembly 1 are the contents of the manual hollow glass window built-in sunshade product lifting device in patent publication number CN202280409U. The components and working principle of the magnetic control handle 2 are the contents of the hollow louver aluminum-plastic combination magnetic control handle 2 in patent publication number CN219012211U.

[0032] Specifically, the working principle of the guide rail locking structure of this magnetically controlled insulated glass curtain wall is as follows: In use, the tail-type guide rail 31, compared to traditional tracks, has a tail that can be pressed against the bottom of the door / window trim for better fixation. Due to the magnetic attraction between the magnetic control handle 2 and the inner magnet assembly 1, when the magnetic control handle 2 moves up or down, it will cause the inner magnet assembly 1 to move up or down. One end of the stop bar 42 abuts against the slot 36, and the stop bar 42 is in a locked state. This prevents the magnetic control handle 2 from sliding up or down under the cooperation of the stop bar 42 and the serrated slot 36. Simultaneously, the ratchet 44 and pawl 46 are linked with the rotating shaft 41. When the stop bar 42 is locked into the slot 36, the ratchet 44 is stopped by the pawl 46. The unidirectional engagement and double locking structure can withstand greater external forces. Even if the stop bar 42 is temporarily disengaged from the slot 36 due to extreme vibration, the ratchet 44 and pawl 46 can still lock the rotating shaft 41 to prevent the magnetic control handle 2 from sliding and demagnetizing. When unlocking is required, pressing the pawl 46 will cause the pawl 46 to disengage from the ratchet 44. At this time, the rotating shaft 41 can be rotated counterclockwise to separate the stop bar 42 from the slot 36 of the serrated strip 35. The stop bar 42 is in the unlocked state, and one end of the stop bar 42 is no longer in contact with the slot 36. At this time, the magnetic control handle 2 can be pulled up or pushed down to make a pair of T-shaped sliders 34 on one side of the magnetic control handle 2 slide stably inside the groove, thereby moving the inner magnet group 1 up or down.

[0033] It should be noted that all standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
