Description

TECHNICAL FIELD

[0001] The utility model relates to door and window lock technical field, concretely relates to a linkage pushing structure and switch lock linkage device. BACKGROUND

[0002] At present, the windows widely used in factory buildings, stadiums, office buildings, teaching buildings, apartment buildings, houses and commercial-residential buildings and the like in the market are mostly manually operated out-pushing windows, which are composed of a pair of wind stays and a pair of friction hinges installed at the upper middle parts of both sides of the window frame, a handle at the bottom edge of the window sash and a pushing connecting rod aluminum slot lock point assembly in the slot of the bottom edge, and the opening and closing of the window is completed through manual pushing and pulling operation. In the era of the increasingly popular application of intelligent automation and intelligent remote control technology, such manually operated windows are not suitable for the times.

[0003] There are windows on the market that use electric control to realize the functions of suspension opening and closing, unlocking and locking, which are divided into two types: one is an external type, that is, most of the window openers are chain type or electric telescopic rod type, but such externally mounted windows have exposed mechanisms and wires, which are not only unsightly but also unsafe, and also make people feel that there is no grade. The other is a concealed type, that is, an electric window opener is installed on one side of the window frame to control the opening and closing of the window, and an electric lock box is installed at the bottom edge of the window sash to control the unlocking and locking of the window sash. This concealed type of window opener combined with an electric lock box is not only aesthetically pleasing but also safe to use. However, the mechanism arrangement and control system are more complex, and the production and installation are difficult. The more mechanisms there are, the more problems may occur, and the cost of after-sales service and quality complaints will also increase. Due to the addition of multiple mechanisms, the direct cost increases.

[0004] Therefore, the applicant previously applied for a Chinese utility model patent with the application number CN202411485083.8, but the linkage pushing structure of this scheme is slightly complex, and the pushing and pulling stroke is small. The actual arrangement position of the lock point stop block provided at the bottom edge of the window frame often deviates from the theoretical position. Because the pushing and pulling stroke of this scheme is small, after the window is completely closed, the connecting rod lock point pin sleeve does not move or does not fully move to the position for being clamped with the lock point stop block, and the connecting rod lock point pin sleeve and the lock point stop block cannot be locked or cannot be fully locked, resulting in that the window cannot be locked or cannot be fully locked after being closed, which affects the locking effect of the window. UTILITY MODEL CONTENTS

[0005] Therefore, the utility model provides a linkage pushing structure and a switch lock linkage device to solve the problem of the small pushing and pulling stroke of the current linkage pushing structure, which affects the locking effect of the window.

[0006] In the first aspect, the utility model provides a linkage pushing structure, which comprises:

[0007] The first connecting piece is vertically slidingly arranged on the connecting support, and is adapted to be connected with the push-pull mechanism;

[0008] The second connecting piece is transversely slidingly arranged on the connecting support, and is adapted to be connected with the bottom groove connecting rod with the push-pull protruding pin;

[0010] Under the action of external force, the first connecting piece pushes the second connecting piece to move transversely through the free-bending push-pull connecting piece, so that the vertical stroke of the first connecting piece is completely converted into the transverse stroke of the second connecting piece; or, under the action of external force, the second connecting piece pushes the first connecting piece to move vertically through the free-bending push-pull connecting piece, so that the transverse stroke of the second connecting piece is completely converted into the vertical stroke of the first connecting piece.

[0076] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0077] The utility model discloses a window opening and closing and lock linkage mechanism, which eliminates the electric lock box and simplifies the mechanism. The rack drives the connecting rod to press down, drives the rocker arm to rotate, and the rocker arm push-pull protrusion pushes and pulls the bottom groove connecting rod when the rocker arm rotates, so as to realize the unlocking or locking of the sash. However, the rack and rocker arm structure of the scheme is slightly complex, and because the rotation range of the rocker arm of the scheme is limited, the pushing and pulling stroke of the bottom groove connecting rod is small.

[0078] The actual arrangement position of the lock point stop block arranged at the bottom edge of the window frame often deviates from the theoretical position, and the accurate clamping of the connecting rod lock point pin sleeve and the lock point stop block cannot be ensured. Because the pushing and pulling stroke of the scheme is small, after the window is completely closed, the connecting rod lock point pin sleeve does not move or does not move sufficiently to the position of clamping with the lock point stop block, the connecting rod lock point pin sleeve and the lock point stop block cannot be locked or cannot be fully locked, which affects the locking effect of the window.

[0079] Therefore, the utility model provides a window opening and closing and lock opening and closing linkage device, which can be pushed and pulled in a wider range through the free bending push-pull connecting piece, so as to significantly increase the pushing and pulling stroke. The increased pushing and pulling stroke ensures that the connecting rod lock point pin sleeve can move sufficiently to the position of clamping with the lock point stop block, and improves the locking reliability after the window is closed.

[0080] The following will be combined with Figures 1 to 12 to describe the linkage pushing structure of the first aspect of the utility model and the opening and closing and lock linkage device of the second aspect of the utility model in detail.

[0081] According to the embodiment of the utility model, first, a linkage pushing structure is provided, which is combined with Figures 1 to 7 As shown in the figure, it comprises a first connecting piece 6, a second connecting piece 5 and a free bending push-pull connecting piece 12.

[0082] The first connecting piece 6 is vertically slidingly arranged on the connected support, and the first connecting piece 6 is adapted to be connected with the push-pull mechanism.

[0083] The second connecting piece 5 is transversely slidingly arranged on the connected support, and the second connecting piece 5 is adapted to be connected with the bottom groove connecting rod 13 with the push-pull protruding pin 52.

[0084] The free bending push-pull connecting piece 12 is arranged in the limiting groove 113 at the corner of the connected support, one end of the free bending push-pull connecting piece 12 is connected with the first connecting piece 6, the other end of the free bending push-pull connecting piece 12 is connected with the second connecting piece 5, and the free bending push-pull connecting piece 12 is a push-pull member which can move freely in the limiting groove.

[0085] Under the action of external force, the first connecting piece 6 pushes the second connecting piece 5 to move transversely through the free bending push-pull connecting piece 12, so that the vertical stroke of the first connecting piece 6 is completely converted into the transverse stroke of the second connecting piece 5. Or under the action of external force, the second connecting piece 5 pushes the first connecting piece 6 to move vertically through the free bending push-pull connecting piece 12, so that the transverse stroke of the second connecting piece 5 is completely converted into the vertical stroke of the first connecting piece 6.

[0086] The above-mentioned linkage pushing structure introduces the free bending push-pull connecting piece 12, which can move freely in the limiting groove 113 and is connected with the first connecting piece 6 and the second connecting piece 5. The design of the free bending push-pull connecting piece 12 enables the entire linkage structure to perform push-pull operation in a wider range, thereby significantly increasing the push-pull stroke. The increased push-pull stroke ensures that the connecting rod locking point pin sleeve can be fully moved to the position of being clamped with the locking point stop block, thereby improving the locking reliability after the window is closed.

[0087] The design of the free bending push-pull connecting piece 12 allows it to be adjusted in the limiting groove 113 according to actual needs to adapt to different installation errors and position deviations. The first connecting piece 6 and the second connecting piece 5 respectively slide in the vertical direction and the transverse direction, which ensures that each component can be flexibly adjusted during the entire push-pull process, so that the connecting rod locking point pin sleeve and the locking point stop block can be accurately clamped, thereby improving the accuracy and reliability of the locking, ensuring that the window can be completely locked after being closed, and improving the safety and sealing performance.

[0088] This embodiment reduces unnecessary complex components and simplifies the overall structure through optimized design. The design of the free-bending push-pull connector 12 not only simplifies the structure but also enhances the stability and durability of the system, reducing the failure rate. It simplifies the manufacturing and assembly process, improves the reliability and service life of the system, and reduces maintenance costs.

[0089] In some embodiments, the free-bending push-pull connector 12 is a chain. The chain has excellent bending and stretching properties, allowing it to move freely within the limiting groove 113, adapting to the space constraints at the corners of the integrated bracket. This flexibility allows the chain to adjust its position according to actual needs, ensuring smoother linkage between the first connector 6 and the second connector 5. This enables the entire linkage structure to perform push-pull operations over a wider range, significantly increasing the push-pull stroke. Specifically, when the user pushes or pulls the window, the chain bends and stretches as needed, ensuring that the linkage locking pin sleeve can move fully to the position where it engages with the locking stop block.

[0090] On the other hand, a chain is composed of multiple links, each of which can serve as an independent connection point, thus effectively transmitting push and pull forces. Through the multi-point connection characteristic of the chain, the push and pull forces can be evenly distributed across each link, avoiding damage or failure caused by excessive force at a single point.

[0091] In some embodiments, the two ends of the free-bending push-pull connector 12 are respectively provided with a first positioning pin 121 and a second positioning pin 122. The side of the second connector 5 is provided with a second connecting hole 51, and the second positioning pin 122 on the free-bending push-pull connector 12 is hinged to the second connecting hole 51; the lower end of the first connector 6 is provided with a first connecting hole 63, and the first positioning pin 121 on the free-bending push-pull connector 12 is hinged to the first connecting hole 63. When the free-bending push-pull connector 12 is a chain, the first positioning pin 121 and the second positioning pin 122 are the chain shafts at both ends of the chain. In this embodiment, the first positioning pin 121 and the second positioning pin 122, connected by a hinge, allow the free-bending push-pull connector 12 to be angled within the limiting groove 113 as needed, ensuring precise engagement between the connecting rod locking pin sleeve and the locking stop block.

[0092] According to an embodiment of the present invention, in a second aspect, a switch-lock linkage device is provided, including a supporting bracket, a push-pull mechanism, a linkage pushing structure, and a bottom groove connecting rod 13. A limiting groove 113 is provided at the corner of the supporting bracket, and the supporting bracket is suitable for installation on a window sash. The push-pull mechanism is disposed on the supporting bracket and is adapted to drive the linkage pushing structure to perform a push-pull action under the action of external force. One end of the linkage pushing structure is connected to the push-pull mechanism, and the other end of the linkage pushing structure is connected to the bottom groove connecting rod 13. The bottom groove connecting rod 13 has a push-pull protrusion 52, which is adapted to be snapped into place with a locking point stop on the window frame.

[0093] The switch lock linkage device described above is applied to the locking and unlocking of a window, and can also be applied to other structures that need to be positioned. Taking the application of the switch lock linkage device to a window as an example, when a user applies an external force (for example, through a sliding push piece at the end of a window opener actuator) to the push-pull mechanism, the push-pull mechanism transmits the force to the linkage push structure. The linkage push structure moves in the limiting groove 113, driving the bottom groove connecting rod 13. The push-pull protruding pin on the bottom groove connecting rod 13 comes into contact with the lock point stop block on the window frame, and finally realizes the snap connection, completing the closing and locking action of the window. When the user applies an external force in the opposite direction, the push-pull mechanism drives the linkage push structure to move in the opposite direction. The push-pull protruding pin is disengaged from the lock point stop block, allowing the window to be unlocked and opened.

[0094] Due to the good bending and stretching performance of the free bending push-pull connecting piece 12, it can move freely in the limiting groove 113, significantly increasing the push-pull stroke. It ensures that the connecting rod lock point pin sleeve can move to the position of being fully connected with the lock point stop block, improving the locking accuracy. The accuracy and reliability of the locking are improved, ensuring that the window can be completely locked after being closed, improving the safety and sealing performance. The chain design simplifies the overall structure, reduces unnecessary complex components, and reduces the manufacturing and assembly difficulty.

[0095] In some embodiments, the limiting groove 113 is provided with an outer guide groove piece 3 and an inner guide groove piece 4, and the outer guide groove piece 3 and the inner guide groove piece 4 are buckled to form a circular arc segment push-pull movable friction track, and the free bending push-pull connecting piece 12 moves along the circular arc segment push-pull movable friction track.

[0096] In this embodiment, the outer guide groove piece 3 and the inner guide groove piece 4 are both main body arc piece structural members with surface hardening treatment, and are respectively buckled to the outer and inner groove surfaces of the bending push-pull connecting piece sliding groove arc groove segment of the connected support body 1 and the connected support cover 2, to provide a back-and-forth push-pull movable friction support surface for the free bending push-pull connecting piece 12, and to separate the free bending push-pull connecting piece 12 from the sliding groove surface of the connected support body 1 and the connected support cover 2 during movement.

[0097] In some embodiments, the linkage push structure is a rack push-pull assembly, and the first connecting piece 6 in the linkage push structure is a rack. The push-pull mechanism includes a rotating groove structure, which is provided on the connected support and has a rotating gear portion that engages with the rack. Under the action of an external force, the rotating groove structure rotates to push or pull the linkage push structure to move, so as to push or pull the bottom groove connecting rod 13 to move in the window sash unlocking or locking stroke.

[0098] Two rack and pinion 8 are positioned in the upper part of the bracket long arm 108 of the integrated bracket body 1. Specifically, the rack and pinion 8 are riveted in the rack and pinion mounting hole 105 of the integrated bracket body 1. The two rack and pinion 8 pass through the two rack mounting elongated holes 62 on the first connector 6 respectively, so that the vertical movement of the first connector 6 is limited by the rack and pinion 8.

[0099] The free-bending push-pull connector 12 is a push-pull component with pins at both ends, capable of free-flowing through the groove and achieving zero or very small length compression. One end is hinged to the first connecting hole 63 at the lower end of the rack via a pin hole, and the other end is hinged to the connecting hole at the tail end of the second connector 5 via a pin hole. The free-bending push-pull connector 12 is installed in the sliding groove cavity after the integrated bracket body 1 and the integrated bracket cover 2 are fastened together, or directly using the arc-shaped friction surface of the side wall of the sliding cavity groove, or using the outer guide groove plate 3 and the inner guide groove plate 4 to provide an arc-shaped push-pull movement friction track surface. The second connector 5 is a rod with a large and a small end. The small end has a connecting hole for hinged to the pin hole of the free-bending push-pull connector 12, and the large end has a push-pull protrusion.
