Description

Technical Field

[0001] This utility model relates to the technical field of escape devices, and in particular to a support arm structure for an escape barrier. Background Technology

[0002] An escape window is a window installed inside a building, usually located on a security grille, and has specific dimensions and opening mechanisms to provide an escape route in an emergency.

[0003] For example, Chinese patent application number 202310704057.9, entitled "A Glass Railing Hidden Escape Device," describes it as "comprising a railing frame and a glass block enclosing the railing frame. The railing frame and at least one glass block are connected by a locking structure, and an escape basket is attached to the railing frame via a wire-laying mechanism. The escape basket has a folded form and an unfolded form; the folded form is used for storage within the railing frame, and the unfolded form is used for escape." Existing escape windows all rely on... A hinged lever serves as the support rod after the escape barrier is deployed. This lever needs to bear the combined weight of the escapee and the escape barrier. However, because the lever needs to be hinged to be stored inside the escape window, when the escape barrier is deployed, the hinge point of the lever almost has to bear the combined weight of the escapee and the escape barrier. This makes the hinge point of the lever prone to breaking due to the inability to withstand such a heavy weight. Since the escape window is used at a high altitude, if the hinge point of the lever breaks, the escapee will be at risk of falling. Utility Model Content

[0004] The purpose of this invention is to provide a support arm structure for an escape hatch.

[0005] To achieve the above objectives, the present invention adopts the following solution:

[0006] An escape hatch support arm structure includes a window frame, a storage cavity on the top crossbeam of the window frame, and swing rods symmetrically hinged within the storage cavity.

[0007] The swing arm consists of a fixed base and a rotating rod. The fixed base is symmetrically fixed to the top of the storage cavity, and the rotating rod is rotatably set at the bottom of the fixed base.

[0008] The suspension rope assembly is hollow, with the fixed base and the rotating rod arranged in a hollow manner. The suspension rope assembly is located on one side of the fixed base in the storage cavity. One end of the suspension rope assembly passes through the fixed base and extends out from the front end of the rotating rod. The end of the suspension rope assembly extending out of the rotating rod is connected to the escape barrier.

[0009] A reinforcing structure is provided on the inner wall of the storage cavity and at the front end of the rotating rod to increase the load-bearing capacity of the swing rod.

[0010] As a further embodiment of this utility model, the fixing base includes a fixing shaft symmetrically fixed to the top of the storage cavity, a limiting plate fixed to the bottom of the fixing shaft, and a bearing sleeved on the fixing shaft.

[0011] As a further embodiment of this utility model, the fixed shaft is designed to be inclined, with one end of the fixed shaft extending inclinedly into the storage cavity.

[0012] As a further embodiment of this utility model, the rotating rod includes a rotating sleeve disposed at the bottom of the fixed shaft and covering the limiting plate and the bearing, and a load-bearing rod is fixed at the bottom of the rotating sleeve.

[0013] As a further embodiment of this utility model, the load-bearing rod is L-shaped.

[0014] As a further embodiment of this utility model, the suspension rope assembly includes a fixed plate fixed inside the storage cavity on one side of the fixed seat, a suspension rope fixed on the fixed plate, a rotating shaft provided at the front end of the load-bearing rod for lateral rotation, one end of the suspension rope passing through the fixed shaft and extending out of the load-bearing rod after passing around the rotating shaft, and the end of the suspension rope extending out of the load-bearing rod is connected to the escape barrier.

[0015] As a further embodiment of this utility model, the fixing plate and the storage cavity are provided with screw holes, and the fixing plate is fixed to the storage cavity by screws.

[0016] As a further embodiment of this utility model, the reinforcing structure includes a first ring fixedly disposed at the bottom of the storage cavity at the front end of the fixed shaft, a second ring fixedly disposed at the front end of the load-bearing rod, and a steel rope connected between the first ring and the second ring.

[0017] In summary, the advantages of this utility model over existing technologies are as follows: In the event of a fire, after the escape route is unfolded, the reinforcing structure located between the inner wall of the storage cavity and the front end of the rotating rod will share some of the weight at the connection point between the fixed seat and the rotating rod on the swing arm. This prevents the total weight of the escape route and the escape route from being entirely applied to the connection point between the fixed seat and the rotating rod, thereby increasing the maximum weight the escape window can withstand and preventing the connection point between the fixed seat and the rotating rod from breaking and causing the escapee to fall. Furthermore, the fixed shaft on the swing arm is inclined, so when the escape window is opened, the rotating rod will automatically unfold under the weight of the swing arm itself. Once unfolded, the rotating rod will not close automatically without external force and will remain in the unfolded state. Attached Figure Description

[0026] The utility model will be further described below with reference to the accompanying drawings and specific embodiments: Figures 1 to 5 The escape hatch support arm structure shown includes a window frame 1, a storage cavity 2 on the top crossbeam of the window frame 1, and swing rods 3 symmetrically hinged within the storage cavity 2.

[0027] The swing arm 3 is composed of a fixed base 110 and a rotating rod 120. The fixed base 110 is symmetrically fixed to the top of the storage cavity 2, and the rotating rod 120 is rotatably disposed at the bottom of the fixed base 110.

[0028] The suspension rope assembly 130 is hollow, and the fixed base 110 and the rotating rod 120 are hollow. The suspension rope assembly 130 is provided in the storage cavity 2 on one side of the fixed base 110. One end of the suspension rope assembly 130 passes into the fixed base 110 and extends out from the front end of the rotating rod 120. The end of the suspension rope assembly 130 extending out of the rotating rod 120 is connected to the escape rail.

[0029] A reinforcing structure 140 is provided on the inner wall of the storage cavity 2 and at the front end of the rotating rod 120 to increase the load-bearing capacity of the swing rod 3.

[0030] A further embodiment of the fixing seat 110 in this utility model: The fixing seat 110 includes a fixing shaft 111 symmetrically fixed to the top of the storage cavity 2, a limiting plate 112 fixed to the bottom of the fixing shaft 111, and a bearing 113 sleeved on the fixing shaft 111.

[0031] A further embodiment of the fixed shaft 111 in this utility model: the fixed shaft 111 is designed with an inclination, and one end of the fixed shaft 111 extends inclination into the storage cavity 2.

[0032] A further embodiment of the rotating rod 120 in this utility model: The rotating rod 120 includes a rotating sleeve 121 disposed at the bottom of the fixed shaft 111 and covering the limiting plate 112 and the bearing 113, and a load-bearing rod 122 is fixed at the bottom of the rotating sleeve 121.

[0033] A further embodiment of the load-bearing rod 122 in this utility model: the load-bearing rod 122 is L-shaped.

[0034] A further embodiment of the suspension rope assembly 130 of this utility model: The suspension rope assembly 130 includes a fixing plate 131 fixed in the storage cavity 2 and located on one side of the fixing seat 110. A suspension rope 132 is fixed on the fixing plate 131. A rotating shaft 133 is provided at the front end of the load-bearing rod 122 for lateral rotation. One end of the suspension rope 132 passes through the fixing shaft 111 and passes around the rotating shaft 133 before extending out of the load-bearing rod 122. One end of the suspension rope 132 extending out of the load-bearing rod 122 is connected to the escape railing.

[0035] A further embodiment of the fixing plate 131 in this utility model: the fixing plate 131 and the storage cavity 2 are provided with screw holes, and the fixing plate 131 is fixed to the storage cavity 2 by screws.

[0036] A further embodiment of the reinforcing structure 140 in this utility model: The reinforcing structure 140 includes a first ring 141 fixedly disposed at the bottom of the storage cavity 2 at the front end of the fixed shaft 111, a second ring 142 fixedly disposed at the front end of the load-bearing rod 122, and a steel rope 143 connected between the first ring 141 and the second ring 142.

[0037] When using, such as Figure 2 and Figure 5 As shown in the figure, the fixed shaft 111 is designed with an inclination. One end of the fixed shaft 111 extends inward into the storage cavity 2. Therefore, when a fire occurs and the escape window is opened, the rotating rod 120 will automatically unfold along the axis of the fixed shaft 111 under its own weight. Because the front end of the rotating rod 120 is inclined downward after unfolding, it will not close on its own without external force and will remain in the unfolded state. This can prevent the escaper from accidentally closing the rotating rod 120 during escape. Because the fixed shaft 111 is designed with an inclination, the rotating rod 120 will also automatically unfold. This prevents the escape barrier from being accidentally opened during escape due to the rotating rod 120 not being fully unfolded. The reinforcing structure 140 can share part of the weight of the connection point between the fixed seat 110 and the rotating rod 120 after the escape barrier is fully unfolded, so that the total weight of the escaper and the escape barrier is not entirely applied to the connection point between the fixed seat 110 and the rotating rod 120.

[0038] The foregoing has shown and described the basic principles and main features of the utility model, as well as its advantages. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the utility model.
