Description

Technical Field

[0001] This utility model relates to the field of high-altitude escape equipment technology, and in particular to a high-altitude safety escape window. Background Technology

[0002] In emergencies such as fires and earthquakes, traditional escape routes, such as staircases and elevators, are often blocked, trapping people and making escape difficult. In such critical situations, high-altitude safety escape windows play a crucial role. Equipped with deceleration devices, these escape windows create a fast and safe high-altitude escape route for residents, helping them escape safely.

[0003] However, escape windows on the market generally have shortcomings, such as limited functionality, complex operation, long activation time, low reliability, and large placement space requirements, making them impractical for the general public. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a high-altitude safety escape window, which adopts a unique mechanical structure design. Even in the event of a fire, there is no risk of failure, and the reliability is extremely high. This solves the problems of existing high-altitude safety escape devices, which require large placement space, have complex usage methods, and are prone to failure in special circumstances.

[0005] The technical solution of this utility model is as follows:

[0006] A high-altitude safety escape window includes a window frame, with a rope storage compartment and a deceleration mechanism respectively located on the upper two sides of the window frame, a fixing post for S-shaped winding of the escape rope located on the upper inner side of the window frame, and a quick-opening mechanism located on the lower side of the window frame; the escape rope is stored in the rope storage compartment.

[0007] The reduction mechanism includes a grooved rope gear, an escape wheel, and an escape fork. The grooved rope gear is connected to the escape wheel through a reduction gear, and the escape wheel cooperates with the escape fork.

[0008] The quick-opening mechanism includes a baffle, a switch plate, and a locking assembly. The baffle is located on the lower side of the window frame, and its inner side is arrayed with several columns for S-shaped winding of the escape rope. The locking assembly is located below the deceleration mechanism and includes an arc hook lock and a connecting rod. The arc hook lock is rotatably connected to the window frame, with one end connected to the window frame via an elastic member. The other end of the arc hook lock has a hook and is movably connected to one side of the switch plate via the connecting rod. The other side of the switch plate is rotatably connected to the window frame. The baffle has a latch, the position of which corresponds to the position of the hook, and the two cooperate to form a self-locking mechanism. At least two springs are provided on both sides of the lower part of the window frame. The springs extend horizontally, with one end fixed to the window frame and the other end in contact with the baffle.

[0009] One end of the escape rope is fixed inside the rope storage compartment, and the other end is S-shaped wound between the column and the fixed column, then leads out around the rope groove gear. Pulling down the switch plate rotates the arc hook lock via the connecting rod, causing the hook of the arc hook lock to disengage from the lock. Under the elastic force of the spring, the baffle is popped open, the column is released from the S-shaped wrapped escape rope, and pulling the end of the escape rope drives the rope groove gear to rotate. Under the interaction of the escape wheel and escape fork, the rope decelerates. The rope groove gear is a gear with rope grooves on its outer surface.

[0010] This technical solution involves installing a baffle plate with the column pointing towards the window frame, pressing the spring to engage the hook of the arc-shaped hook lock with the baffle plate's latch. Under the tension of the elastic component, both remain in a self-locking state. The escape rope is led out from the rope storage compartment, sequentially winding around the lower column and the upper fixed column in an S-shape, finally passing over the rope groove gear and leading out. When the escape function needs to be activated, pulling the switch opens the elastic component, causing the arc-shaped hook lock to rotate. The hook disengages from the latch, and the spring releases the baffle plate, freeing the escape rope within the window frame. The user can then secure the escape rope to their body and escape through the middle of the frame. During the pulling of the escape rope, the rope drives the rope groove gear to transmit power to the escape wheel, causing the escape wheel and escape fork to interact. In this continuous transmission, friction occurs between the escape fork and the escape wheel teeth, further slowing down the escapee's descent and ensuring a safe landing speed for self-rescue.

[0011] As a further improvement of this utility model, the elastic member is a tension spring.

[0012] As a further improvement of this utility model, the fixing column and the top inner side of the window frame are provided with holes for the escape rope to pass through.

[0013] As a further improvement of this utility model, the switch plate is provided with a handle strip.

[0014] As a further improvement of this utility model, the cross-section of the switch plate is "F" shaped.

[0015] As a further improvement of this utility model, the front frame plate on the lower side of the window frame is provided with a plurality of guide holes for the column to pass through.

[0016] As a further improvement of this utility model, the lower rear frame plate of the window frame is provided with a fixing hole corresponding to the position of the guide hole, and the column extends into the fixing hole through the guide hole.

[0017] As a further improvement of this utility model, the locking assembly includes two components, which are located at both ends of the lower side of the window frame and correspond to the position of the baffle.

[0018] As a further improvement of this utility model, the deceleration mechanism includes a deceleration chamber housing, the grooved gear, the escape wheel and the escape fork are located inside the deceleration chamber housing, a flywheel is provided inside the deceleration chamber housing, the flywheel is rotatably connected to the deceleration chamber housing through a mainspring, and the fork head of the escape fork is connected to the axis of the flywheel.

[0019] As a further improvement of this utility model, the bottom of the deceleration chamber housing is provided with a hole for the escape rope to pass through below the rope groove gear.

[0020] As a further improvement of this utility model, the fixed column is provided with reinforcing ribs, and the groove of the window frame is provided with "X"-shaped reinforcing ribs.

[0021] As a further improvement of this utility model, the free end of the escape rope is connected to a safety strap.

[0022] As a further improvement of this utility model, the latch is a latch groove that matches the hook body.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] This utility model's technical solution combines the functions of a window and an escape route. It can be used as a window and also as an escape aid. It is simple to use, opens quickly, and is suitable for all personnel. Furthermore, this high-altitude safety escape window is a purely mechanical mechanism, requiring no electricity and eliminating the risk of failure in various special circumstances.

[0039] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figures 1 to 8 As shown, a high-altitude safety escape window includes a window frame 1. The upper two sides of the window frame 1 are respectively provided with a rope storage compartment 2 and a deceleration mechanism 3. The upper inner side of the window frame 1 is provided with a fixing post 11 for the escape rope 5 to be wound in an S-shape. The lower side of the window frame 1 is provided with a quick opening mechanism 4. The escape rope 5 is provided in the rope storage compartment 2.

[0041] The reduction mechanism 3 includes a grooved gear 31, an escape wheel 33, and an escape fork 34. The grooved gear 31 is connected to the escape wheel 33 through a reduction gear 32, and the escape wheel 33 cooperates with the escape fork 34.

[0042] The quick-opening mechanism 4 includes a baffle 41, a switch plate 42, and a locking assembly. The baffle 41 is located on the lower side of the window frame 1, and its inner side is arrayed with several columns 43 for S-shaped winding of the escape rope 5. In this embodiment, there are two locking assemblies, located at both ends of the lower side of the window frame 1, corresponding to the positions of the baffle 41. One of the locking assemblies is located below the deceleration mechanism 3. The locking assembly includes an arc-shaped hook lock 44 and a connecting rod 45. The arc-shaped hook lock 44 is rotatably connected to the window frame 1. One end of the arc-shaped hook lock 44 is connected to the window frame 1 via a tension spring 46, and the other end of the arc-shaped hook lock 44 is provided with a hook body 47. The other end of the arc-shaped hook lock 44 is movably connected to one side of the switch plate 42 via the connecting rod 45. The other side of the switch plate 42 is rotatably connected to the window frame 1. The baffle 41 is provided with a latch 48, the position of which corresponds to the position of the hook body 47, and the two cooperate to form a self-locking mechanism. At least two springs 12 are provided on both sides of the lower part of the window frame 1. Spring 12 extends horizontally, with one end fixed to the window frame 1 and the other end in contact with the baffle 41; one end of the escape rope 5 is fixed in the rope storage compartment 2, and the other end is S-shaped wound between the column 43 and the fixed column 11, and then led out by passing around the rope groove gear 31; pull down the switch plate 42, and drive the arc hook lock 44 to rotate through the connecting rod 45, so that the hook body 47 of the arc hook lock 44 disengages from the lock 48, and under the elastic force of spring 12, the baffle 41 is popped open, the column 43 is disengaged from the S-shaped wrapped escape rope 5, and the end of the escape rope 5 is pulled, and the escape rope 5 drives the rope groove gear 31 to rotate, and deceleration is performed under the interaction of the escape wheel 33 and the escape fork 34.

[0043] The switch plate 42 is provided with a handle strip. Furthermore, the cross-section of the switch plate 42 is U-shaped. The flared lower part of the switch plate 42 serves as a handle.

[0044] The front frame plate 13 on the lower side of the window frame 1 is provided with a plurality of guide holes 14 for the column 43 to pass through. The rear frame plate 15 on the lower side of the window frame 1 is provided with fixing holes 16 corresponding to the positions of the guide holes 14, and the column 43 passes through the guide holes 14 and extends into the fixing holes 16.

[0045] The deceleration mechanism 3 includes a deceleration chamber housing 37. The grooved gear 31, escape wheel 33, and escape fork 34 are located inside the deceleration chamber housing 37. A flywheel 35 is provided inside the deceleration chamber housing 37. The flywheel 35 is rotatably connected to the deceleration chamber housing 37 via a mainspring 36. The fork head of the escape fork 34 is connected to the axis of the flywheel 35. The bottom of the deceleration chamber housing 37, below the grooved gear 31, has a hole for the escape rope 5 to pass through.

[0046] Furthermore, the fixed column 11 is provided with reinforcing ribs, and the slot of the window frame 1 is provided with "X"-shaped reinforcing ribs.

[0047] Furthermore, the free end of the escape rope 5 is connected to a safety strap.

[0048] During installation, the rope storage compartment 2 is installed in the mounting position on one side above the window frame 1, and the deceleration mechanism 3 is installed on the other side above the window frame 1. On the lower side of the window frame 1, the baffle 41 is positioned with the column 43 facing the window frame 1, so that the column 43 passes through the guide hole 14 and extends into the fixing hole 16. This process will compress the spring 12. Then, the arc hook lock 44 is rotated so that the hook 47 of the arc hook lock 44 engages with the latch 48 of the baffle 41. Under the tension of the tension spring 46, the arc hook lock 44 and the latch 48 are kept in a self-locking state. Then, the escape rope 5 is led out from the rope storage compartment 2, passed into the window frame 1, and successively wrapped around the column 43 on the baffle 41 and the fixing post 11 on the upper side of the window frame 1 in an S-shape, and finally led out by passing around the rope groove gear 31. When the escape function needs to be activated, pull the switch plate 42. This causes the connecting rod 45 to rotate the arc hook lock 44, pulling open the tension spring 46. Under the action of the tension spring 46, the hook 47 of the arc hook lock 44 disengages from the latch 48. The spring 12 then pushes open the baffle 41, releasing the escape rope 5 inside the window frame 1. The user can then secure the escape rope 5 to their body and escape through the middle of the frame. During the pulling of the escape rope 5, the rope 5 drives the rope groove gear 31 to transmit power to the escape wheel 33. The escape wheel 33 interacts with the escape fork 34. During the continuous transmission, friction occurs between the teeth of the escape fork 34 and the escape wheel 33, further slowing down the descent of the escapee and ensuring that the escapee lands on the ground at a safe descent speed, thus achieving self-rescue.

[0049] The high-altitude safety escape window in this embodiment is installed in the user's home and can be fixed with expansion bolts, possessing strong load-bearing capacity. Through a mechanical mechanism, the user can easily open the escape window by simply pulling the switch plate 42. If the initial opening fails, simply continue pulling the switch plate 42 outwards; there's no need to release the switch plate 42 and pull again, saving time and preventing the user from missing the best escape opportunity due to panic. After successful opening, if subsequent use is required, simply pull the switch plate 42 outwards again and manually reinstall the baffle 41 back into the frame for normal use.

[0050] The high-altitude safety escape window of this embodiment has a simple structure, is easy to assemble, and has a low rate of disassembly failure. Its ingenious structural design allows it to serve as both a window and an escape route. It is simple and quick to use, suitable for all personnel, and requires minimal opening force, making it suitable for all self-rescue operators. Furthermore, this high-altitude safety escape window is a purely mechanical mechanism, requiring no electricity and eliminating the risk of failure in various special circumstances. Moreover, the main components of this high-altitude safety escape window can be injection molded from high-strength plastic, making it suitable for low-cost mass production.
