Description

Technical Field

[0001] The present invention relates to the technical field of door and window hardware, and in particular to an automatic locking structure and a window sash structure. Background Art

[0002] In the modern building curtain wall industry, many curtain wall sashes lack automatic locking systems. This means that in high winds or typhoon conditions, the window sashes are affected by outdoor wind pressure and automatically close, but then open due to negative indoor wind pressure. This cycle of closing and opening severely impacts the window sashes, causing damage and raising safety concerns. This is particularly true in high-rise buildings, where the impact of outdoor wind pressure is particularly severe. To address this issue, a typhoon lock hook with automatic locking is designed, ensuring both regular use and durability in high winds or typhoon conditions. Summary of the Invention

[0003] The object of the present invention is to provide an automatic locking structure and a window sash structure to solve one or more technical problems existing in the prior art and at least provide a beneficial option or create conditions.

[0004] The technical solutions adopted to solve the above technical problems are:

[0005] The present invention provides an automatic locking structure, including a sliding component and a positioning component. The sliding component includes a sliding hook seat, a hook elastic member, and a hook body. The hook body is rotatably arranged on the sliding hook seat, and the hook elastic member is arranged on the sliding hook seat; the positioning component includes a positioning seat, a stop plate body, and a stop plate elastic member. The positioning seat is provided with a positioning and fixing column, and the stop plate body is provided with a stop plate hook body with an opening facing the sliding hook seat. The stop plate body is rotatably arranged on the positioning seat, and the stop plate elastic member is arranged on the positioning seat. The stop plate elastic member is used to provide a first elastic force that causes the stop plate hook body to engage with the positioning and fixing column, and the hook elastic member is used to provide a second elastic force that causes the hook body to contact the stop plate body and causes the stop plate body to move away from the positioning and fixing column while the hook body engages with the positioning and fixing column.

[0006] The beneficial effects of the present invention are:

[0007] The sliding hook seat is installed on the window body, and the positioning seat is installed on the window frame. Under the action of wind, the window body approaches the window frame, the hook body contacts the stop plate body and causes the stop plate body to move away from the positioning and fixing column, and the hook body is engaged with the positioning and fixing column, thereby achieving free locking under the action of wind;

[0008] When locked, as the handle rotates, the sliding hook seat moves to the left relative to the positioning seat, the hook body is no longer locked with the positioning and fixing column and no longer abuts the stop plate body, and the stop plate hook body is locked with the positioning and fixing column under the action of the stop plate elastic member;

[0009] When opening, as the handle rotates, the sliding hook seat moves to the right relative to the positioning seat. During the movement, the stop plate hook body blocks the hook body. The hook body rotates under the action of the stop plate hook body and cannot be locked with the positioning fixed column. The opening of the stop plate hook body faces the sliding hook seat, which does not restrict the opening of the fan body, thereby opening it smoothly.

[0010] As a further improvement to the above technical solution, the sliding hook seat is provided with a hook spring limiting post, the hook elastic member includes a hook spring body, and the hook spring body is provided with a first ear hook and an extension rod at each end. The first ear hook abuts the hook spring limiting post, and the extension rod is provided with a second ear hook that engages with the hook body. The provision of the first ear hook and the second ear hook better provides rotational force for the hook body.

[0011] As a further improvement of the above technical solution, the hook body is provided with an arc-shaped guide portion that rotates around the hook spring limiting column. When the hook body is engaged, it cooperates with the hook elastic member to facilitate the hook body to smoothly lock with the positioning fixing column.

[0012] As a further improvement of the above technical solution, the sliding hook seat is provided with a hook positioning column, the hook body is rotatably arranged on the hook positioning column, and the hook spring body is sleeved on the hook positioning column, with a compact structure.

[0013] As a further improvement of the above technical solution, the positioning and fixing column and the hook positioning column are both sleeved with a sleeve to facilitate the hook spring body to provide torsional force.

[0014] As a further improvement of the above technical solution, the hook body is provided with a first abutting surface abutting against the stop plate hook body. When there is wind to close freely, it is more conducive to the hook body to push open the stop plate hook body, thereby realizing the locking of the hook body with the positioning fixing column and automatically locking the fan body.

[0015] As a further improvement to the above technical solution, the hook body is provided with a first abutting surface that abuts the stop plate hook body, and the stop plate body is provided with a second abutting surface that abuts the hook body. During opening, the second abutting surface causes the hook body to be pressed against and rotated, preventing the hook body from locking with the positioning post, allowing the door to open smoothly.

[0016] As a further improvement of the above technical solution, the stop plate elastic member includes a stop plate spring body, and both ends of the stop plate spring body are respectively provided with a first abutting rod abutting against the positioning seat and a second abutting rod abutting against the stop plate body.

[0017] The present invention also provides a window sash structure, comprising any one of the above-described automatic locking structures, a window frame, and a sash body, wherein the sliding assembly slidably mounts the sash body, and the positioning assembly is disposed on the window frame. The window sash structure equipped with the automatic locking structure can automatically lock under the action of wind, is not affected by negative indoor wind pressure, and cyclically closes and opens the sash, effectively protecting the sash and reducing the risk of damage to the sash. Manual opening and closing is also possible.

[0018] As a further improvement of the above technical solution, the fan body is provided with a transmission rod structure and a handle, and the handle is transmission-connected to the sliding hook seat via the transmission rod structure. The handle drives the sliding hook seat to move, thereby realizing manual opening and closing.

[0019] As a further improvement to the above technical solution, the sash body is provided with multiple lock seats, and the window frame is provided with multiple locking members that engage with the lock seats. These locking members are in driving connection with the transmission rod structure. The multiple lock seats and lock seat structure improve the airtightness and locking security of the window sash structure. Combined with the automatic locking mechanism, the window sash structure can be opened and closed manually while also being able to be locked freely under wind pressure.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] In the modern building curtain wall industry, many curtain wall fan bodies 300 do not have an automatic locking system, that is, in windy or typhoon weather, the window sash is affected by the outdoor wind pressure and automatically closes the window, and is affected by the indoor negative wind pressure to open the window sash. This cycle of closing and opening will seriously affect the window sash, causing damage to the window sash (hereinafter also referred to as the fan body 300), and will also cause safety problems. Especially in high-rise buildings, the impact of outdoor wind pressure is particularly serious. In view of the above situation, a set of dynamic locking structures that can automatically lock is designed, which can be used for both conventional use and strong wind or typhoon weather. In the present invention, when used conventionally or in typhoon weather, the fan body 300 can be locked after closing, and the automatic locking structure plays a major role. When operating the fan body 300, the automatic locking structure does not affect the normal locking and opening of the fan body 300. Reference Figures 1 to 18 The present invention provides an automatic locking structure and a window sash structure, and makes the following embodiments:

[0044] In some embodiments, reference Figure 6 and Figure 7A window sash structure includes an automatic locking structure of the following embodiment, a window frame 400, and a sash body 300. The automatic locking structure includes a sliding assembly 100 and a positioning assembly 200. The sliding assembly 100 is slidably installed on the lower edge of the sash body 300. The positioning assembly 200 is set on the window frame 400. The sash body 300 is provided with a transmission rod structure 500 and a handle 600. The handle 600 is connected to the sliding hook seat 110 through the transmission rod structure 500. The transmission rod structure 500 includes multiple aluminum connecting rods and multiple anglers. The aluminum connecting rods and the anglers are connected. The handle 600 and the transmission rod structure 500 are existing technologies and will not be described in detail here. By rotating the handle 600, the aluminum connecting rods and the anglers are driven to move, so that the sliding assembly 100 moves relative to the positioning assembly 200, thereby achieving manual locking and closing. After the automatic locking structure is added, the automatic locking structure is described in detail below. The automatic locking structure allows the window structure to automatically lock under the action of wind, and is not affected by the negative wind pressure in the room. The window sash is closed and opened in a cycle, which effectively protects the window sash and reduces the occurrence of window sash damage. At the same time, it does not affect the manual opening and closing of the window sash.

[0045] The automatic locking structure is described in detail below.

[0046] Reference Figures 1 to 4 An automatic locking structure includes a sliding assembly 100 and a positioning assembly 200. The sliding assembly 100 includes a sliding hook seat 110, a hook elastic member 120, and a hook body 130. The sliding hook seat 110 is set on the edge of the fan body 300. The two ends of the sliding hook seat 110 are respectively connected to aluminum connecting rods. It can move left and right relative to the fan body 300 under the action of the handle 600. The hook body 130 is rotatably mounted on the sliding hook seat 110. The hook elastic member 120 is mounted on the sliding hook seat 110. The hook body 130 is the main component for achieving free wind locking.

[0047] The positioning assembly 200 includes a positioning seat 210, a stop plate body 220, and a stop plate elastic member 230. The positioning seat 210 is fixed on the window frame 400, and can be fixed by screws or rivets. The positioning seat 210 is provided with a positioning fixing column 211, and the positioning fixing column 211 can be locked with the hook body 130 under the action of wind force. The stop plate body 220 is provided with a stop plate hook body 221 with an opening facing the sliding hook seat 110. The opening of the stop plate hook body 221 faces the sliding hook seat 110, so that when the fan body 300 is opened, the stop plate hook body 221 hooks the positioning fixing column 211, and the fan body 300 can also be opened, and it cannot play the role of fixing the fan body 300.

[0048] The stop plate body 220 is rotatably set on the positioning seat 210, and the stop plate elastic member 230 is set on the positioning seat 210. The stop plate elastic member 230 is used to provide a first elastic force so that the stop plate hook body 221 is engaged with the positioning and fixing column 211, and the hook elastic member 120 is used to provide a second elastic force so that the hook body 130 contacts the stop plate body 220 and makes the stop plate body 220 move away from the positioning and fixing column 211 and the hook body 130 is engaged with the positioning and fixing column 211.

[0049] The principle of the automatic locking structure: the sliding hook seat 110 is installed on the window body 300, and the positioning seat 210 is installed on the window frame 400. Under the influence of wind, the window body 300 approaches the window frame 400, and the hook body 130 contacts the stop plate body 220, causing the stop plate body 220 to move away from the positioning and fixing column 211. The hook body 130 is engaged with the positioning and fixing column 211, achieving free locking under the influence of wind.

[0050] When locking, as the handle 600 rotates, the sliding hook seat 110 moves leftward relative to the positioning seat 210, and the hook body 130 is no longer locked with the positioning and fixing column 211 and no longer abuts the stop plate body 220. The stop plate hook body 221 is locked with the positioning and fixing column 211 under the action of the stop plate elastic member 230. At this time, the locking of the door sash 300 and the window frame 400 mainly depends on other components, such as the lock seat 310 and the locking point member 320 mentioned below;

[0051] When opening, as the handle 600 rotates, the sliding hook seat 110 moves to the right relative to the positioning seat 210. During the movement, the stop plate hook body 221 will block the hook body 130. The hook body 130 rotates under the action of the stop plate hook body 221 and cannot be locked with the positioning fixing column 211. The opening of the stop plate hook body 221 faces the sliding hook seat 110, which does not restrict the opening of the fan body 300, thereby opening smoothly.

[0052] It should be noted that the sliding assembly 100 slides to install the window frame 400, and the positioning assembly 200 is set on the fan body 300. The present invention does not make specific limitations. That is to say, the positions of the sliding assembly 100 and the positioning assembly 200 can be interchanged, and the specific setting method can be adjusted accordingly by those skilled in the art.

[0053] Further improvement, the sliding hook seat 110 is provided with a hook positioning column 111, and the hook body 130 is rotatably provided on the hook positioning column 111, referring to Figures 9 to 12 During the engagement process, the hook body 130 rotates around the hook positioning column 111, making the movement of the hook body 130 more stable. The hook spring body 121 is sleeved on the hook positioning column 111, and the structure is compact, which is conducive to better providing elastic force to the hook body 130.

[0054] Furthermore, the sliding hook base 110 is provided with a hook spring limiting post 112. The hook elastic member 120 includes a hook spring body 121, with a first ear hook 122 and an extension rod 123 at each end. The first ear hook 122 abuts the hook spring limiting post 112, and the extension rod 123 is provided with a second ear hook 124 that engages with the hook body 130. The hook spring body 121 provides torsional force, allowing the hook body 130 to engage with the positioning and fixing post 211. The provision of the first ear hook 122 and the second ear hook 124 further enhances the rotational force of the hook body 130.

[0055] In some other embodiments, the two ends of the hook spring body 121 can be adjusted accordingly according to the shape of the hook body 130 to form a hook shape or a straight torsion arm.

[0056] As a further improvement, the hook body 130 is provided with an arc-shaped guide portion 133 that rotates around the hook spring limit column 112, which is conducive to the rotation of the hook body 130 around the hook positioning column 111, and then when the hook body 130 is engaged, it cooperates with the hook elastic part 120, which is conducive to the smooth locking of the hook body 130 with the positioning and fixing column 211.

[0057] The positioning and fixing column 211 is sleeved with a sleeve 113 to facilitate the hook spring body 121 to provide torque.

[0058] For further improvement, refer to Figure 2 、 Figure 11 and Figure 12 The hook body 130 is provided with a first abutting surface 131, which abuts against the stop plate hook body 221. When there is wind to freely close, it is more conducive for the hook body 130 to push open the stop plate hook body 221, thereby realizing the locking of the hook body 130 with the positioning fixing column 211 and automatically locking the fan body 300.

[0059] As a further improvement, the hook body 130 is provided with a first abutting surface 131 that abuts the stop plate hook body 221, and the stop plate body 220 is provided with a second abutting surface 132 that abuts the hook body 130. During opening, the second abutting surface 132 causes the hook body 130 to be supported and rotated, and the hook body 130 cannot be locked with the positioning and fixing column 211, allowing the door 300 to open smoothly.

[0060] Furthermore, the sliding hook seat 110 includes a mounting plate 114, with support connecting parts 115 connected to both ends of the mounting plate 114, and the hook elastic member 120 and the hook body 130 are disposed on the mounting plate 114. The support connecting part 115 is connected to the aluminum connecting rod.

[0061] Furthermore, the stop plate elastic member 230 includes a stop plate spring body 231 , and a first abutting rod 233 and a second abutting rod 234 are respectively provided at both ends of the stop plate spring body 231 . The first abutting rod 233 abuts against the positioning seat 210 , and the second abutting rod 234 abuts against the stop plate body 220 .

[0062] Furthermore, the positioning seat 210 is provided with a stop plate positioning column 212, the stop plate body 220 is rotatably provided on the stop plate positioning column 212, and the stop plate spring body 231 is sleeved on the stop plate positioning column 212, so that the stop plate body 220 rotates more stably.

[0063] Furthermore, the positioning seat 210 includes a positioning fixing plate 213 and an upper fixing plate 214. A side abutment plate 215 is connected between the positioning fixing plate 213 and the upper fixing plate 214 to abut against the first abutment rod 233. The present invention has a simple structure, does not require milling for installation (milling-free installation), and is easy and quick to repair and replace.

[0064] The opening and closing of the window sash structure are further introduced in detail.

[0065] The present invention also provides an embodiment of a window sash structure, in which the sash body 300 is provided with a plurality of lock seats 310, and the window frame 400 is provided with a plurality of locking point components 320. The lock seats 310 are locked with the lock seats 310, and the locking point components 320 are connected to the transmission rod structure 500 in a transmission manner. The multiple lock seats 310 and the lock seat 310 structure improve the air tightness of the window sash structure and the firmness of the locking. Combined with the automatic locking structure, the window sash structure can be opened and closed manually while being freely locked under the action of wind. When the window is closed, the present invention can achieve a better sealing effect by linking the locking point components 320 around the sash body 300 with the handle 600, as shown in FIG. Figure 8 .

[0066] After rotating the handle 90° 600 to open, see Figure 5 When the sliding assembly 100 is closed normally or automatically closed due to typhoon, the hook body 130 of the sliding assembly 100 of the present invention hooks the positioning fixing column 211 of the positioning assembly 200. Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 Under typhoon environmental factors, after the fan body 300 is closed, the hook body 130 hooks the positioning fixing column 211 and the fan body 300 is automatically locked to prevent the fan body 300 from being affected by wind pressure, opening and closing back and forth, and avoiding damage to the fan body 300 and other safety problems.

[0067] Locking details (hook body 130 hooks the positioning fixing column 211): When the window sash is closing, the hook spring body 121 acts on the hook body 130, and the stop plate spring body 231 acts on the stop plate body 220; when the window sash approaches the window frame 400, the hook body 130 first contacts the stop plate body 220 (see Figure 10 ); The sash continues to close the hook body 130 contacts the positioning fixing column 211 (see Figure 11 ); The stop plate body 220 is pushed by the hook body 130 under the action of the stop plate spring body 231, avoiding the hook body 130 to avoid mutual interference; when the window sash is finally closed, the hook body 130 completely hooks the positioning fixing column 211 (see Figure 12 ), to achieve the purpose of automatic locking under wind pressure.

[0068] After the handle 600 is closed (see Figure 9 ), rotate the handle 600° to 0° (see Figure 13 ), the surrounding locking parts 320 buckle the lock seat 310, and the fan body 300 is completely locked to achieve the best state of sound insulation, heat insulation and air tightness.

[0069] When the handle 600 rotates from 90° to 0°, the aluminum connecting rod moves in the direction of the arrow, thereby driving the sliding assembly 100 to move. At this time, the hook body 130 of the sliding assembly 100 of the present invention is separated from the positioning and fixing column 211 of the positioning assembly 200. The stop plate body 220 is tightly attached to the positioning and fixing column 211 under the action of the stop plate spring body 231. The surrounding locking points buckle the lock seat 310, and the fan body 300 is in a completely locked state (see Figure 13 、 Figure 14 、 Figure 15 ).

[0070] After the handle 600 is fully locked (see Figure 13 、 Figure 14 、 Figure 15 ), rotate the handle 600 90° ( Figure 16 ), the surrounding locking points are separated from the lock seat 310, and the fan body 300 is in the ready-to-open mode.

[0071] When the handle 600 rotates from 0° to 90°, the aluminum connecting rod moves in the direction of the arrow, thereby driving the sliding assembly 100 to move. The stop plate body 220 is pressed against the positioning and fixing column 211 under the action of the stop plate spring body 231. At this time, the hook body 130 in the sliding assembly 100 of the present invention is supported by the positioning and fixing column 211 of the positioning assembly 200. The hook body 130 cannot hook the positioning and fixing column 211, and the surrounding locking points are separated from the lock seat 310, and the fan body 300 can be opened (see Figure 16 、 Figure 17 、 Figure 18 ).

[0072] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
