Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors and windows, in particular to a translation extrusion structure for sealing sliding doors and windows. Background Art

[0002] The sealing method of sliding windows mainly relies on the use of sealing strips. The sealing strip is a material used to fill the gap between the window sash and the window frame. The sealing strip has elasticity and can achieve the sealing performance between the window sash and the window frame.

[0003] The gap between the window sash and the window frame of the existing sliding window is fixed. The sealing between the window sash and the window frame can only be achieved by the resilience of the sealing strip. Over time, the sealing strip will gradually age, lose its elasticity and sealing performance, and cannot guarantee the sealing between the window sash and the window frame.

[0004] To improve the sealing between the window sash and the window frame, in the prior art, there is a sliding window hardware system that squeezes the window sash tightly against the window frame. The existing sliding window hardware includes a handle, a transmission mechanism arranged on three sides of the window sash, and driving locking points. The transmission mechanism includes a corner piece installed at the corners of the window sash. The driving locking points are located on the upper and lower sides of the window sash. A pulley housing cooperating with the driving locking points is provided on the window sash, and a pulley slidably connected to the window frame is installed therein. By switching the state of the handle, the transmission mechanism can be driven to move up and down outside the window sash, and then drive the driving locking points to squeeze the pulley and the corresponding part of the window sash tightly against the window frame. However, the sliding window hardware system of the prior art is only installed on three sides of the window sash, and there are disconnected parts in the hardware system, so that when the window sash is opened or closed, the spring pieces in the corner piece are respectively subjected to thrust or tension. After long-term use, the spring pieces are prone to breakage. Content of the Utility Model

[0005] To solve the technical problems existing in the above background art, the utility model provides a translation extrusion structure for sealing sliding doors and windows.

[0006] The technical solution of the utility model is as follows:

[0007] A translation extrusion structure for sealing sliding doors and windows is arranged on the sliding doors and windows. The translation extrusion system includes a handle and a transmission mechanism connected in transmission. The transmission mechanism includes corner pieces arranged at the four corners of the window sash. The corner piece includes a spring tension piece. Adjacent spring tensions are connected by transmission parts. A plurality of transmission parts and the corner pieces surround the edge of the window sash. Squeezing units are arranged on one side in the horizontal direction of the four corner pieces. The squeezing units are arranged between the window sash and the window frame of the sliding doors and windows;

[0008] A single extrusion unit includes a mounting base which is arranged above or below a neighboring corner fitting. A moving member that is slidably connected to the window frame is provided inside the mounting base near the window frame side. The moving member is connected to a transmission member and is slidably connected to the mounting base. The sliding direction is perpendicular to the vertical plane where the pushing and pulling direction of the window sash is located. The moving member can drive the window sash to laterally move as a whole in a direction perpendicular to the vertical plane where it is located.

[0009] A plurality of transmission members and spring tension pieces that are connected end to end are arranged around the outer frame of the window frame. When closing the window sash, the position of the operating handle is switched. The rotation of the operating handle drives the transmission members and the spring tension pieces of the corner fitting to move in the same direction. The spring tension pieces are pulled to move, causing the lock to act on the slide rail, and moving the corner fitting and the window sash inward as a whole, squeezing the sealing strip to achieve the sealing between the window sash and the window frame. When opening the window sash, the rotation of the operating handle drives the transmission members and the spring tension pieces of the corner fitting to move in the opposite direction together, causing the spring tension pieces to also be pulled and move, and preventing the phenomenon that the spring tension pieces push the transmission members, thus improving the service life of the spring tension pieces.

[0010] A single extrusion unit further includes a slide rail which is located between a neighboring mounting base and the spring tension piece and is connected to the spring tension piece. An "S"-shaped chute is provided inside the slide rail. A lock is provided on the upper part of the mounting base located below. The lower part of the lock is connected to the mounting base. The lock can be slidably connected in the "S"-shaped chute, enabling the window sash to laterally move as a whole in a direction perpendicular to the vertical plane where it is located, and be able to approach or move away from the window frame.

[0011] The structures of the moving members at different upper and lower positions are different and can correspond to the upper and lower positions inside the window frame. There is no guide rail above the window frame. The moving member located above the window frame is set as a side shift wheel, and the sliding direction of the side shift wheel is the same as the pushing and pulling direction and the side shift direction of the window frame. A guide rail is provided below the window frame for connecting to the window sash and also serving as a load-bearing function. The moving member located below the window frame is set as a roller, and the roller is slidably connected to the guide rail of the window frame, and its sliding direction is the same as the pushing and pulling direction of the window frame.

[0012] The sliding connection structure between the above-mentioned slide rail and the corner fitting is that a long groove is opened on the housing of the corner fitting. The ratio of the length of the long groove to the length of the slide rail is 1 - 1.5, enabling the slide rail to cooperate with the window sash and the transmission member to effectively move in the long groove, facilitating the overall lateral movement of the window sash and the transmission member. The slide rail is slidably connected in the long groove, and the sliding direction is the same as the pushing and pulling direction of the window sash. Its upper part is connected to the spring tension piece through a connecting member.

[0013] Regarding the specific structure of the "S"-shaped chute, the length direction of the "S"-shaped chute is set along the sliding direction of the slide rail, including an arc-shaped locking groove, a transition groove, and an arc-shaped opening groove that are connected in sequence. The arc directions of the arc-shaped locking groove and the arc-shaped opening groove are opposite. The arc direction of the arc-shaped locking groove faces the window frame. When the window sash is in the locked state, the lock is located in the arc-shaped locking groove. When the window sash is in the open state, the lock moves from the arc-shaped locking groove to the arc-shaped opening groove.

[0014] To facilitate the disassembly and installation of the sliding rail, the upper part of the sliding rail is detachably connected with a quick-release plate, which is located above the elastic pull tab and is slidably connected with the corner fitting.

[0015] Regarding the structure of the window sash, the window sash includes two vertically arranged vertical frames. The handle is arranged on one of the vertical frames and is connected with the transmission mechanism. The transmission part on the other vertical frame is provided with an L-shaped plate that is slidably connected with the window frame. When the window sash moves inward as a whole, the L-shaped plate can play a limiting role in the window sash to prevent the window sash from detaching from the outer side of the window frame.

[0016] The moving direction of the L-shaped plate is that one side of the L-shaped plate is hooked on one side of the window frame, and the sliding direction with the window frame is the moving direction and the side-moving direction of the window sash along the sliding rail. When the window sash moves inward as a whole, the L-shaped plate can hook the window frame to prevent the window sash from detaching from the window frame.

[0017] Regarding the connection mechanism between the L-shaped plate and the transmission part, the L-shaped plate is connected with the transmission part through a limit seat. The length direction of the limit seat is consistent with the length direction of the vertical frame. A U-shaped plate is slidably connected in the limit seat, and its sliding direction is consistent with the side-moving direction of the window sash. The two ends of the U-shaped plate along the length direction are connected with the limit seat through pin shafts, so that the U-shaped plate can slide along the width direction of the limit seat to cooperate with the movement of the L-shaped plate along the side-moving direction of the window sash.

[0018] The moving distance of the U-shaped plate is that the maximum sliding length of the U-shaped plate in the limit seat is greater than the maximum sliding length of the L-shaped plate and the window sash in the side-moving direction.

[0019] To facilitate that the window sash does not shake after being integrally extruded inward or integrally moved inward, the vertical distance between the centers of the arc-shaped locking groove and the arc-shaped opening groove is consistent with the maximum side-moving distance of the window sash.

[0020] The beneficial effects of the present utility model are as follows:

[0021] The transmission mechanism is arranged around the outer frame of the window sash. A spring pull tab is arranged in the corner fitting, and the spring pull tab is connected with the transmission part. When the handle is switched from the open state to the closed state, by pulling the transmission part and the spring pull tab around the window frame for one week, the sliding rail is driven to move, so that under the action of the "S"-shaped sliding groove of the sliding rail, the rotator and the window sash are driven to move inward by a certain distance, and the sealing strip between the window sash and the window frame is extruded, improving the sealing performance between the window sash and the window frame;

[0022] When the handle is switched from the closed state to the open state, the spring pull tab and the transmission part are pulled in the reverse direction. The sliding rail moves along the pushing and pulling direction of the window frame. The position of the lock catch relative to the position in the "S"-shaped sliding groove moves from one end to the other end, driving the rotator and the window sash to move inward by a certain distance, and the window sash can be pushed and pulled to move;

[0023] When the window sash is opened and closed, the spring pull piece is always subjected to tension. Compared with the prior art spring pull piece which is subjected to both tension and thrust, the spring pull piece can be prevented from breaking and its service life can be increased.

[0024] The window sash and window frame are sealed by overall side pressure, and the window sash presses the sealing strip inward. Compared with the prior art which only squeezes on three sides of the window frame, this sealing method makes the window sash evenly stressed and avoids the phenomenon of poor sealing in the part of the window sash where no hardware is set.

[0042] According to the above structure, the functions that the present utility model can achieve are as follows. Refer to Figure 1 、 Figure 2 and Figure 3 As shown, when the handle 3 switches from the open state to the closed state (window sash 2 in the closed state), by pulling the transmission part 5 and the spring tab 41 that surround the window frame 1 for one week, the slide rail 9 is driven to move, so that under the action of the "S"-shaped chute 91 of the slide rail 9, the lock 8 drives the rotator and the window sash 2 to move inward by a certain distance, and squeezes the sealing strip between the window sash 2 and the window frame 1, improving the sealing performance between the window sash 2 and the window frame 1;

[0043] Refer to Figure 5 、 Figure 6 and Figure 7 As shown, when the handle 3 switches from the closed state to the open state (window sash 2 in the open state), the spring tab 41 and the transmission part 5 are pulled in the reverse direction, and the slide rail 9 moves along the pushing and pulling direction of the window frame 1. The lock 8 moves from one end to the other end relative to its position in the "S"-shaped chute 91, driving the rotator and the window sash 2 to move inward by a certain distance, and the window sash 2 can be pushed and pulled to move.

[0044] ​​When the window sash 2 is closed, the handle 3 rotates to drive the transmission member 5 and the spring tab 41 of the corner fitting 4 to move in the same direction. The spring tab 41 is pulled to move, so that the lock catch 8 acts on the slide rail 9, and the corner fitting 4 and the window sash 2 as a whole move inward integrally, squeezing the sealing strip to achieve the sealing between the window sash 2 and the window frame 1; when the window sash 2 is opened, the handle 3 rotates to drive the transmission member 5 and the spring tab 41 of the corner fitting 4 to move in the opposite direction together, so that the spring tab 41 is also pulled to move, and the phenomenon that the spring tab 41 pushes the transmission member 5 will not occur, improving the service life of the spring tab 41.

[0045] The sliding connection structure between the above-mentioned slide rail 9 and the corner fitting 4 is that a long groove 42 is formed on the housing of the corner fitting 4, and the length ratio of the long groove 42 to the length of the slide rail 9 is 1 - 1.5. The slide rail 9 is slidably connected in the long groove 42, and the sliding direction is the same as the pushing and pulling direction of the window sash 2, and its upper part is connected to the spring tab 41 through a connecting member.

[0046] See Figure 8 、 Figure 9 and Figure 10 As shown in, the specific structure of the "S"-shaped chute 91 is that the length direction of the "S"-shaped chute 91 is arranged along the sliding direction of the slide rail 9, including an arc-shaped locking groove 911, a transition groove 912 and an arc-shaped opening groove 913 that are connected in sequence.
