Description

Technical Field

[0001] The invention relates to the technical field of door and window locks, and in particular to a linkage pushing structure and a switch lock linkage device. Background Art

[0002] At present, the windows widely used in factories, stadiums, office buildings, teaching buildings, apartment buildings, houses, commercial and residential buildings, etc. are mostly manually operated outward-pushing windows, which are composed of a pair of wind braces and a pair of friction hinges installed in the middle and upper parts of both sides of the window frame, a handle at the bottom of the window sash, and a push-link aluminum groove locking point assembly in the bottom groove to form a hanging opening and closing and unlocking and locking mechanism, and the window is opened and closed by manual push-pull operation. In the era of the increasing popularization of intelligent automation and intelligent remote control application technologies, this kind of manual window seems out of date.

[0003] There are two types of windows on the market that use electric control to achieve suspended opening and closing, unlocking and locking: one is the external type, that is, most of them use chain-type window openers or electric telescopic rod window openers, but when this type of external window is in use, the mechanism and wires are exposed, which is not only unsightly, but also unsafe, and also makes people feel that it is not classy. The other is the concealed type, that is, an electric window opener is concealed on one side of the window frame to open and close the window, and then an electric lock box is concealed on the bottom of the window sash to unlock and lock the window sash. This concealed installation method of the window opener superimposed on the electric lock box is both beautiful in appearance and safe to use. However, the mechanism layout and control system are more complicated, and it is difficult to manufacture and install. The more mechanisms there are, the more possible problem links will increase accordingly, and the after-sales service costs and quality complaints will also increase. Due to the addition of multiple mechanisms, direct costs increase.

[0004] To this end, the applicant has previously applied for a Chinese invention patent with application number CN202411485083.8, but the linkage push structure of the scheme is slightly complicated and the push-pull stroke is relatively small. The actual arrangement position of the locking point block set at the bottom of the window frame often deviates from the theoretical position. Because the push-pull stroke of the scheme is relatively small, after the window is fully closed, the connecting rod locking point pin sleeve does not move or does not fully move to the position for engagement with the locking point block, and the connecting rod locking point pin sleeve and the locking point block cannot be locked or cannot be fully locked, resulting in the window being unable to be locked or unable to be fully locked after closing, affecting the locking effect of the window. Summary of the invention

[0005] In view of this, the present invention provides a linkage push structure and a switch lock linkage device to solve the problem that the current linkage push structure has a small push and pull stroke, which affects the window locking effect.

[0006] In a first aspect, the present invention provides a linkage driving structure, comprising:

[0007] A first connecting member, the first connecting member is vertically slidably disposed on the one-piece bracket, and the first connecting member is suitable for connecting with the push-pull mechanism;

[0008] A second connecting member, the second connecting member is transversely slidably arranged on the one-piece bracket, and the second connecting member is suitable for connecting with a bottom groove connecting rod with a push-pull convex pin;

[0009] A free-bending push-pull coupling member, the free-bending push-pull coupling member is arranged in a limiting groove at a corner of the conjoined bracket, one end of the free-bending push-pull coupling member is connected to a first connecting member, and the other end of the free-bending push-pull coupling member is connected to a second connecting member, and the free-bending push-pull coupling member is a push-pull member that can move freely in the limiting groove;

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

[0011] The beneficial effects of the above linkage driving structure are:

[0012] By introducing the free-bending push-pull connector, the component can move freely in the limit groove and connect the first connector and the second connector. The design of the free-bending push-pull connector enables the entire linkage structure to perform push-pull operations 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 fully move to the position where it is engaged with the locking point block, thereby improving the locking reliability after the window is closed.

[0013] The design of the free-bending push-pull connector allows it to be adjusted in the limit slot according to actual needs to adapt to different installation errors and position deviations. The first connector and the second connector slide vertically and horizontally respectively, ensuring that the components can be flexibly adjusted during the entire push-pull process, and ultimately achieving precise engagement between the connecting rod locking point pin sleeve and the locking point block, thereby improving the locking accuracy and reliability, ensuring that the window can be completely locked after closing, and improving safety and sealing.

[0014] This embodiment reduces unnecessary complex components and simplifies the overall structure by optimizing the design. The design of the free-bending push-pull connector not only simplifies the structure, but also enhances the stability and durability of the system and reduces the failure rate. It simplifies the manufacturing and assembly process, improves the reliability and service life of the system, and reduces maintenance costs.

[0015] In an optional embodiment, the free-bending push-pull connecting member is a chain.

[0016] The beneficial effects of the above technical solution are as follows: the chain has good bending and stretching performance, can move freely in the limit groove, and adapt to the space limitation at the corner of the connected bracket. This flexibility enables the chain to adjust its position according to actual needs, ensuring that the linkage between the first connecting member and the second connecting member is smoother, so that the entire linkage structure can be pushed and pulled in a wider range, significantly increasing the push-pull stroke. Specifically, when the user pushes or pulls the window, the chain will bend and stretch as needed to ensure that the connecting rod locking point pin sleeve can fully move to the position where it is engaged with the locking point block.

[0017] On the other hand, the chain is composed of multiple links, each of which can serve as an independent connection point to effectively transmit push and pull forces. Through the multi-point connection characteristics of the chain, the push and pull forces can be evenly distributed to each link, avoiding damage or failure caused by excessive force at a single point.

[0018] In an optional embodiment, the two ends of the free-bending push-pull coupling are respectively provided with a first positioning pin and a second positioning pin;

[0019] A first connecting hole is provided at the lower end of the first connecting member, and the first positioning pin is hinged to the first connecting hole;

[0020] A second connecting hole is provided on the side of the second connecting member, and the second positioning pin is hinged to the second connecting hole.

[0021] The beneficial effects of the above technical solution are: the first positioning pin and the second positioning pin connected in a hinged manner allow the free-bending push-pull connecting part to adjust the angle in the limit groove according to actual needs, ensuring that the connecting rod locking point pin sleeve and the locking point block are accurately engaged.

[0022] In a second aspect, the present invention provides a switch-lock linkage device, comprising:

[0023] A one-piece bracket, wherein a limiting groove is provided at a corner of the one-piece bracket, and the one-piece bracket is suitable for being installed on a window sash;

[0024] A push-pull mechanism, which is arranged on the integrated bracket and is suitable for driving the linkage pushing structure to perform a push-pull action under the action of an external force;

[0025] The linkage push structure has one end connected to the push-pull mechanism and the other end connected to the bottom slot connecting rod;

[0026] A bottom groove connecting rod is provided with a push-pull convex pin, and the push-pull convex pin is suitable for being snap-connected with a locking point stopper on the window frame.

[0027] In an optional embodiment, an outer guide groove plate and an inner guide groove plate are provided in the limit groove, and the outer guide groove plate and the inner guide groove plate are buckled to form a circular arc segment push-pull movable friction track, and the free bending push-pull connecting part moves along the circular arc segment push-pull movable friction track.

[0028] The above technical solution has the following beneficial effects: since the free-bending push-pull connector has good bending and telescopic properties, it can move freely in the limit groove, significantly increasing the push-pull stroke. It ensures that the connecting rod locking point pin sleeve can fully move to the position of engaging with the locking point block, thereby improving the locking accuracy. It improves the locking accuracy and reliability, ensures that the window can be completely locked after closing, and improves safety and sealing. The chain design simplifies the overall structure, reduces unnecessary complex components, and reduces the difficulty of manufacturing and assembly.

[0031] In an optional embodiment, the one-piece bracket comprises a one-piece bracket body and a one-piece bracket cover;

[0032] The one-piece bracket body is provided with a bending push-pull connecting piece groove on one side opposite to the one-piece bracket cover, and the one-piece bracket cover is provided with a cover bending push-pull connecting piece sliding groove on one side opposite to the one-piece bracket body. The one-piece bracket cover is buckled on the bottom of the one-piece bracket body, so that the bending push-pull connecting piece groove and the cover bending push-pull connecting piece sliding groove are surrounded to form the limiting groove;

[0033] The one-piece bracket body includes a bracket long arm, a bracket single arm and a bracket bottom support plate connected therebetween; a bracket bottom support plate is provided in the middle of the main side of the bracket long arm; a bracket mounting portion is provided at the top end of the bracket single arm, and the bracket mounting portion is fixed on the window sash frame assembly.

[0036] In an optional embodiment, a rotary groove unlocking piece is provided on the single arm of the bracket, and the rotary groove unlocking piece is rotatably provided on the single arm of the bracket through an unlocking piece pin;

[0037] The end of the rotary groove unlocking piece close to the rotary groove is provided with an unlocking piece hook portion, which can lock the rotary groove when the unlocking piece hook portion abuts against the rotary groove, and can unlock the rotary groove when the unlocking piece hook portion is separated from the rotary groove; the end of the rotary groove unlocking piece away from the rotary groove is a long strip structure, and the end of the unlocking piece is provided with an unlocking piece pressing tail end;

[0038] A T-shaped flange for unlocking piece is arranged at the top of the rotary groove unlocking piece, and a second torsion spring is sleeved on the unlocking piece pin. One of the torque arms of the second torsion spring abuts against the T-shaped flange for unlocking piece, and the other torque arm of the second torsion spring is suitable for abutting against the bracket mounting part.

[0039] In an optional embodiment, a rotation slot limiting boss is provided on the top of the long arm of the bracket, and the rotation slot limiting boss is suitable for limiting the rotation stroke of the rotation slot and providing slot side support for the rotation slot;

[0040] And / or, a rack tooth portion and a rack mounting elongated hole are provided on the first connecting member, the first connecting member is positioned on the long arm of the bracket by a rack rivet pin passing through the rack mounting elongated hole, and a tooth plate fan-shaped portion is provided on the spiral groove tooth plate, and the tooth plate fan-shaped portion is meshed with the rack tooth portion.

[0041] The present invention has an extremely simple structure and a flat design. It is installed in a wrap-around manner on a corner of the window sash and is used in conjunction with a concealed window opener. When the window is about to be closed, the rotary groove unlocking piece is pressed down to rotate the rotary groove structure, and then the latter pushes the rack push-pull assembly to push the bottom groove connecting rod to lock the window sash, thereby realizing window closing and locking.

[0076] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0077] The Chinese invention patent with application number CN202411485083.8 discloses a window switch and lock linkage mechanism, which eliminates the need for an electric lock box and simplifies the mechanism. The solution uses a rack to drive the connecting rod downward, driving the rocker arm to rotate. When the rocker arm rotates, the rocker arm pushes and pulls the bottom groove connecting rod to unlock or lock the window sash. However, the rack rocker arm structure of the solution is slightly complicated, and because the rocker arm rotation range of the solution is limited, the push-pull stroke of the bottom groove connecting rod is relatively small.

[0078] However, the actual arrangement position of the locking point block set at the bottom edge of the window frame often deviates from the theoretical position, and the precise engagement between the connecting rod locking point pin sleeve and the locking point block cannot be ensured. Since the push-pull stroke of this solution is too small, after the window is fully closed, the connecting rod locking point pin sleeve does not move or does not move fully to the position for engagement with the locking point block, and the connecting rod locking point pin sleeve and the locking point block cannot be locked or cannot be fully locked, resulting in the window being unable to be locked or unable to be fully locked after closing, affecting the locking effect of the window.

[0079] Based on this, the present invention provides a window switch and lock linkage device, which enables the entire linkage structure to perform push-pull operations in a wider range through a free-bending push-pull link, thereby significantly increasing the push-pull stroke. The increased push-pull stroke ensures that the connecting rod locking point pin sleeve can fully move to the position where it is engaged with the locking point block, thereby improving the locking reliability after the window is closed.

[0080] Combine the following Figures 1 to 12 , the linkage pushing structure of the first aspect of the present invention and the switch lock linkage device of the second aspect of the present invention are elaborated in detail.

[0081] According to an embodiment of the present invention, in the first aspect, a linkage driving structure is provided, Figures 1 to 7As shown, it includes a first connecting member 6, a second connecting member 5 and a free-bending push-pull connecting member 12.

[0082] The first connecting member 6 is vertically slidably arranged on the integrated bracket, and the first connecting member 6 is suitable for connecting with the push-pull mechanism.

[0083] The second connecting member 5 is transversely slidably arranged on the integrated bracket, and the second connecting member 5 is suitable for connecting with the bottom groove connecting rod 13 with the push-pull convex pin 52.

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

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

[0086] The above linkage push structure, by introducing the free bending push-pull connector 12, can move freely in the limit groove 113 and connect the first connector 6 and the second connector 5. The design of the free bending push-pull connector 12 enables the entire linkage structure to perform push-pull operations 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 fully move to the position of engaging with the locking point block, thereby improving the locking reliability after the window is closed.

[0087] The design of the free-bending push-pull connector 12 allows it to be adjusted in the limit groove 113 according to actual needs to adapt to different installation errors and position deviations. The first connector 6 and the second connector 5 slide vertically and horizontally respectively, ensuring that each component can be flexibly adjusted during the entire push-pull process, and finally the connecting rod locking point pin sleeve and the locking point block are accurately engaged, improving the locking accuracy and reliability, ensuring that the window can be completely locked after closing, and improving safety and sealing.

[0088] This embodiment reduces unnecessary complex components and simplifies the overall structure by optimizing the 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 and reduces the failure rate. It simplifies the manufacturing and assembly process, improves the reliability and service life of the system, and reduces the maintenance cost.

[0089] In some embodiments, the free-bending push-pull connector 12 is a chain. The chain has good bending and stretching properties, and can move freely in the limit slot 113 to adapt to the space limitations at the corners of the integrated bracket. This flexibility allows the chain to adjust its position according to actual needs, ensuring that the linkage between the first connector 6 and the second connector 5 is smoother, so that the entire linkage structure can perform push-pull operations in a wider range, significantly increasing the push-pull stroke. Specifically, when the user pushes or pulls the window, the chain will bend and stretch as needed to ensure that the connecting rod locking point pin sleeve can fully move to the position where it is engaged with the locking point block.

[0090] On the other hand, the chain is composed of multiple links, each of which can serve as an independent connection point to effectively transmit push and pull forces. Through the multi-point connection characteristics of the chain, the push and pull forces can be evenly distributed to 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 coupling 12 are respectively provided with a first locating pin 121 and a second locating pin 122. The side of the second connecting member 5 is provided with a second connecting hole 51, and the second locating pin 122 on the free-bending push-pull coupling 12 is hinged to the second connecting hole 51; the lower end of the first connecting member 6 is provided with a first connecting hole 63, and the first locating pin 121 on the free-bending push-pull coupling 12 is hinged to the first connecting hole 63. When the free-bending push-pull coupling 12 is a chain, the first locating pin 121 and the second locating pin 122 are chain axes at both ends of the chain. In this embodiment, the first locating pin 121 and the second locating pin 122 connected by an articulated manner allow the free-bending push-pull coupling 12 to be adjusted in angle according to actual needs in the limiting groove 113, ensuring that the connecting rod locking point pin sleeve and the locking point block are accurately engaged.

[0092] According to an embodiment of the present invention, in a second aspect, a switch lock linkage device is provided, comprising a conjoined bracket, a push-pull mechanism, a linkage push structure and a bottom groove connecting rod 13. A limit groove 113 is provided at the corner of the conjoined bracket, and the conjoined bracket is suitable for being installed on a window sash. The push-pull mechanism is provided on the conjoined bracket, and the push-pull mechanism is suitable for driving the linkage push structure to perform a push-pull action under the action of an external force. One end of the linkage push structure is connected to the push-pull mechanism, and the other end of the linkage push structure is connected to the bottom groove connecting rod 13. The bottom groove connecting rod 13 is provided with a push-pull convex pin 52, and the push-pull convex pin 52 is suitable for being snap-connected with a locking point block on the window frame.

[0093] The above-mentioned switch lock linkage device is applied to the locking and unlocking of windows, and can also be applied to other structures that need to be positioned. Taking the application of the switch lock linkage device to windows as an example, when the user applies external force (for example, through the sliding push piece at the end of the 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 limit groove 113, driving the bottom groove connecting rod 13. The push-pull convex pin on the bottom groove connecting rod 13 contacts the locking point block on the window frame, and finally realizes the snap connection, completing the closing and locking action of the window. When the user applies external force in the reverse direction, the push-pull mechanism drives the linkage push structure to move in the reverse direction. The push-pull convex pin disengages from the locking point block, unlocking the window and allowing the window to be opened.

[0094] Since the free-bending push-pull connector 12 has good bending and telescopic properties, it can move freely in the limit groove 113, significantly increasing the push-pull stroke. It ensures that the connecting rod locking point pin sleeve can fully move to the position of engaging with the locking point block, improving the locking accuracy. The locking accuracy and reliability are improved, ensuring that the window can be completely locked after closing, and improving safety and sealing. The chain design simplifies the overall structure, reduces unnecessary complex components, and reduces the difficulty of manufacturing and assembly.

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

[0096] In this embodiment, the outer guide groove plate 3 and the inner guide groove plate 4 are both main arc-shaped plate structural parts with hardened surface, which are respectively clamped on the outer and inner groove surfaces of the arc-shaped groove sections of the bending push-pull connecting part slide of the one-piece bracket body 1 and the one-piece bracket cover 2, so as to provide a friction support surface for the free bending push-pull connecting part 12 for back and forth pushing and pulling activities, and to prevent the free bending push-pull connecting part 12 from scratching and wearing the slide groove surfaces of the one-piece bracket body 1 and the one-piece bracket cover 2 during movement.

[0097] In some embodiments, the linkage push structure is a rack push-pull assembly, and the first connecting member 6 in the linkage push structure is a rack. The push-pull mechanism includes a rotating slot structure, which is arranged on the integrated bracket, and the rotating slot structure has a rotating tooth portion meshing with the rack. Under the action of external force, the rotating slot structure rotates to push or pull the linkage push structure to move, so as to push and pull the bottom slot connecting rod 13 to perform the window sash unlocking or locking stroke movement.

[0098] The two rack rivet pins 8 are positioned in the upper and middle section of the long arm 108 of the one-piece bracket body 1. Specifically, the rack rivet pins 8 are riveted in the rack pin mounting holes 105 of the one-piece bracket body 1. The two rack rivet pins 8 respectively pass through the two rack mounting long strip holes 62 on the first connecting member 6, and then the up and down movement position of the first connecting member 6 is limited by the rack rivet pins 8.

[0099] The free-bending push-pull connector 12 is a push-pull component with pins at both ends that can be freely slotted to completely achieve no length compression or very little length compression.

[0112] In some embodiments, the bottom groove connecting rod 13 is installed in the bottom frame groove of the window sash frame assembly, and the bottom groove connecting rod 13 is an associated execution structure for realizing the locking and unlocking of the window sash. The push-pull hole at one end of the bottom groove connecting rod 13 is nested and connected with the push-pull convex pin gap at the large end of the second connecting member 5, and is driven by the second connecting member 5 in the bottom frame groove of the window sash frame assembly to perform the travel movement of unlocking or locking the window sash.

[0113] The window closing and locking operation of the mechanism of the present invention is as follows:

[0114] During the window closing process, the sliding member at the actuator end of the window opener obliquely joins the sliding groove 19 to close the window, and near the window closing position, the sliding member enters the groove of the rotating groove 9 and continues to push the window sash to close the window. When the window sash is about to close the window, the unlocking piece hook 115 at the tail end of the long arm of the rotating groove unlocking piece 11 hits the side of the window frame and is pressed down, that is, the rotating groove unlocking piece 11 overcomes the elastic torque of the second torsion spring 16 and withdraws the unlocking piece hook 115 originally pressed against the upper end of the rotating groove 9, that is, the side of the end of the rotating groove 9 is unlocked.

[0115] When the sliding member continues to slide down, the rotating groove 9 of the rotating groove structure is moved, overcoming the elastic torque applied by the torque arm of the first torsion spring 15 to the lower side of the fan-shaped tooth portion, driving the rotating groove tooth piece 7 to rotate with the rotating groove shaft column 104 on the integrated bracket as the rotating axis ( Figure 2 The toothed portion of the rotating groove structure drives the rack meshing with the toothed portion to slide downward, and the rack drives the second connecting member 5 of the free bending push-pull connecting member 12 to be pushed out, and the push-pull convex pin at the large end of the second connecting member 5 pushes the bottom groove connecting rod 13 to slide ( Fig.12 The window sash locking action is completed by riveting the connecting rod locking point pin sleeve on the bottom groove connecting rod 13 to the locking point block on the bottom edge of the window frame.

[0116] The unlocking and window opening working actions of the above switch-lock linkage device are as follows:

[0117] During the window opening process, the sliding member at the actuator end of the window opener first moves the rotating groove 9 of the rotating groove structure in the window opening direction, and with the assistance of the elastic torque applied by the torque arm of the first torsion spring 15 in the originally compressed state to the side surface of the lower end of the fan-shaped tooth portion, the rotating groove sticking tooth piece 7 is driven to rotate with the rotating groove shaft column 104 on the integrated bracket as the rotating axis ( Figure 2 The toothed portion of the rotating groove structure drives the rack meshing with the toothed portion to slide upward, and the rack drives the free bending push-pull coupling member 12 and the second connecting member 5 to pull back, and the push-pull convex pin at the large end of the second connecting member 5 drives the bottom groove connecting rod 13 which is nested in the bottom groove of the window frame assembly 20 with a gap to slide ( Fig.12 The window sash unlocking action is completed by riveting the connecting rod locking point pin sleeve on the bottom groove connecting rod 13 and the locking point block on the bottom edge of the window frame.

[0118] At the same time, the unlocking piece hook 115 of the rotating groove unlocking piece 11 gradually separates from the window frame and rotates under the elastic torque of the second torsion spring 16. After the unlocking piece hook 115 rotates to the groove of the rotating groove 9 to align with the oblique sliding groove 19, it rotates back to the position. At this time, the unlocking piece hook 115 presses on the side surface of the upper end of the rotating groove 9, that is, the side of the end of the rotating groove 9 is locked. If the sliding member at the actuator end of the window opener continues to slide along the groove of the rotating groove 9 to the oblique sliding groove 19, and then slides in the groove of the oblique sliding groove 19, and continues to push the window sash, the window sash continues to open to the large angle range.

[0119] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
