Description

Technical Field

[0001] The utility model relates to the technical field related to screen window locks, and in particular to a linkage lock and a screen window system. Background Art

[0002] As modern residential buildings demand ever-increasing living environments, screens, as an integral feature of windows, must not only provide ventilation but also effectively protect against insects, dust, and certain safety features. The locking and closing properties of screens are particularly important in windy environments or where a tight seal is required. Traditionally, rotary screens employ multiple locking mechanisms around the closing edge to enhance sealing and stability. While this design effectively addresses the inadequate sealing of a single lock, it also comes with the added disadvantages of complex and inefficient unlocking.

[0003] Currently, the rotary switch screen locking structure on the market mostly adopts an independent lock design, that is, each locking point needs to be unlocked separately. While this design increases the number of locking points, it also greatly increases the number of actions the user needs to complete when unlocking. Especially in emergency situations or when the screen is frequently opened and closed, the user experience is greatly reduced. Utility Model Content

[0004] In order to overcome at least one of the above-mentioned defects of the prior art, the present invention provides a linkage lock and screen window system, which can solve the problem of difficulty in unlocking at multiple locking points.

[0005] The technical solution adopted by the present invention to solve the problem is:

[0006] A linkage lock comprises: at least two locks, wherein the lock comprises a lock shell, a lock tongue movable in the lock shell and a reset member for resetting the lock tongue and extending it, an unlocking member is provided on the lock tongue, and the unlocking member is used to drive the lock tongue to move along a first direction of contraction of the lock tongue so that the lock tongue is retracted into the lock shell, and the lock is arranged between the locks along a second direction perpendicular to the first direction; a linkage member, a driving member is provided on the linkage member corresponding to the unlocking member of each of the locks, a waist-shaped hole is provided on the driving member, and the waist-shaped hole is inclined to the first and second directions, the unlocking member is slidably arranged in the waist-shaped hole, and when the driving member displaces along the second direction, it drives the unlocking member of each of the locks to displace synchronously.

[0007] By adopting the above solution and the design of the linkage parts, the user only needs to operate the linkage parts to simultaneously drive the unlocking parts of multiple locks, so that all the lock tongues are unlocked synchronously. This greatly reduces the number of actions the user needs to complete, especially when there are many locking points, significantly improving the simplicity and efficiency of the unlocking operation. In emergency situations or when the screen window needs to be opened and closed frequently, the linkage lock design can respond quickly, avoiding the cumbersome unlocking process of traditional independent lock designs, thereby improving the user experience. The number and layout of the locks can be adjusted according to actual needs to accommodate screen windows of different sizes and shapes, which provides strong flexibility.

[0008] Furthermore, the lock case includes: a lock body, a lock groove with an opening on one side of the lock body, and the lock groove is used to accommodate a lock tongue; a lock cover, the lock cover is arranged to cover the opening, and the lock cover is provided with a limiting hole for partially extending the lock tongue; an assembly part, the assembly part is arranged on the side of the lock body away from the opening.

[0009] By adopting the above solution, the lock body, lock cover and assembly part together constitute the complete structure of the lock shell, providing necessary support and guarantee for the extension and retraction of the lock tongue and the fixation of the lock, thereby realizing efficient and convenient unlocking operation.

[0010] Furthermore, the lock tongue includes: a sliding block, which is slidably arranged in the lock groove; a locking portion, which is located on one side of the sliding block and is used to extend from the limiting hole; an unlocking portion, which is located on the other side of the sliding block, and the unlocking member is assembled on the unlocking portion.

[0011] By adopting the above solution, the sliding block and the locking portion can be driven to slide by operating the unlocking portion, thereby achieving unlocking, and the user can complete the unlocking operation easily and quickly.

[0012] Furthermore, the unlocking member is arranged along a third direction, which is perpendicular to the first direction and the second direction. Both ends of the unlocking member protrude from the unlocking portion. Slide rails arranged along the first direction are provided on both sides of the lock body. Both ends of the unlocking member are respectively slidably arranged in the slide rails on both sides of the lock body.

[0013] By adopting the above solution, the unlocking piece cooperates with the slide rails on both sides of the lock body, ensuring that the unlocking piece can be stably installed in the slide rails and maintain close contact with the slide rails during the sliding process, reducing shaking and friction; the user can drive the unlocking piece to slide along the slide rail by operating the linkage piece, thereby synchronously driving the unlocking of all lock tongues.

[0014] Furthermore, a through hole is provided on the lock body along the second direction, and the driving member is passed through the through hole.

[0015] By adopting this solution, when the linkage moves in a specific direction, it connects to the unlocking element of each lock through the driver, and drives them synchronously. The position and size of the perforation must match the driver to ensure that the driver can be stably inserted into the perforation and maintain close contact with the lock body during movement.

[0016] Furthermore, an operating portion is provided on the linkage member, and the operating portion is used to operate the linkage member to move along the second direction.

[0017] By adopting the above solution, the main function of the operating part is to transmit the user's operating force to the linkage part, thereby driving the unlocking part to move synchronously.

[0018] Furthermore, it also includes an assembly plate, the assembly plate has a sliding groove, a plurality of the locks slide in the sliding groove, and a locking member is provided between the sliding groove and the locks.

[0019] By adopting the above solution, the assembly plate serves as a support and installation platform for the locks, so that the locks can be neatly arranged and slide along the sliding grooves, allowing the number and position of the locks to be adjusted according to actual needs to accommodate screens of different sizes and shapes.

[0020] Furthermore, the locking member is arranged toward a bottom edge in the sliding groove, so that the locking member acts on two edges in the sliding groove at the same time.

[0021] By adopting the above solution, such a design enables the locking member to act more directly on the contact surface between the lock and the sliding groove, increasing the contact area between the locking member and the sliding groove, thereby improving the stability and reliability of the locking, while reducing the depth of the groove and reducing the space occupied by the assembly.

[0022] A screen window system comprises a first screen window frame, a second screen window frame, a screen window body and a linkage lock, wherein the lock is assembled on the first screen window frame along a first direction, the screen window body is hinged to the second screen window frame, and a locking groove for engaging with a lock tongue is provided on the side of the screen window body facing the lock.

[0023] By adopting the above scheme, when the user operates the linkage part of the interlocking lock, the driving part can drive the unlocking part to move, thereby driving the lock tongue to move in the direction away from the locking groove to reach the unlocked state. At this time, the screen window can be rotated to open. The overall structure is compact and easy to operate. It can effectively prevent the screen window from being accidentally opened in the unlocked state.

[0024] Furthermore, a recessed portion for accommodating a lock is provided on the edge of the first screen frame facing the locking groove, an assembly groove for assembling the lock is provided on the side of the recessed portion opposite to the locking groove, and a clamping edge for clamping the lock is provided on the side of the recessed portion adjacent to the locking groove.

[0025] By adopting the above scheme, the synergistic effect of the recessed portion, the assembly groove and the clamping edge allows the lock to be firmly installed on the first screen frame and form an effective locking relationship with the locking groove on the screen window body. At the same time, before the lock is fixed, the lock can slide along the recessed portion, that is, between the assembly groove and the clamping edge, without falling off, making assembly more convenient and the quantity and position adjustment more flexible.

[0026] In summary, the interlocking lock and screen window system provided by the present invention has the following technical effects:

[0027] 1. Through the design of the linkage parts, the user only needs to operate once to activate the unlocking parts of multiple locks simultaneously, so that all the lock tongues are unlocked simultaneously. This greatly reduces the number of actions required by the user, especially when there are many locking points, and significantly improves the efficiency and convenience of the unlocking operation;

[0028] 2. Since the interlocking lock can drive multiple locks at the same time, it ensures that all locking points of the screen window are tightly locked when closed, thereby improving the sealing and stability of the screen window. This is especially important in environments that require better sealing, such as areas with strong winds or indoor spaces that need to be isolated from mosquitoes.

[0029] 3. The design of the interlocking lock and screen system is highly flexible. The number and layout of the locks can be adjusted according to actual needs to accommodate screens of different sizes and shapes. This design enables the system to be widely used in various residential and architectural environments.

[0030] 4. In the unlocked state, the interlocking lock can effectively prevent the screen window from being accidentally opened, thereby improving the safety of the family. This design is especially important for families with children or pets. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, they cannot be understood as limiting the present invention.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0042] Example 1 of the present utility model is shown in FIG. Figures 1-6 As shown, a linkage lock is disclosed, comprising: at least two locks 1 and a linkage member 2, the lock 1 comprising a lock housing 11, a lock tongue 12 movable in the lock housing 11 and a reset member 13 for resetting the lock tongue 12 and extending it, preferably, the reset member 13 is a spring, the lock tongue 12 is provided with an unlocking member 14, the unlocking member 14 is used to drive the lock tongue 12 to move along a first direction in which the lock tongue 12 contracts, so that the lock tongue 12 contracts into the lock housing 11, and the lock 1 and the lock 1 are connected along a second direction perpendicular to the first direction. The linkage member 2 is provided with a driving member 3 corresponding to the unlocking member 14 of each of the locks 1. A waist-shaped hole 31 is provided on the driving member 3. The waist-shaped hole 31 is inclined to the first direction and the second direction. The unlocking member 14 is slidably arranged in the waist-shaped hole 31. When the driving member 3 moves along the second direction, it drives the unlocking member 14 of each of the locks 1 to move synchronously. Thus, through the design of the linkage member 2, the user only needs to operate the linkage member 2 to simultaneously drive the unlocking members 14 of multiple locks 1, so that all the lock tongues 12 are unlocked synchronously. This greatly reduces the number of actions the user needs to complete, especially when there are many locking points, and significantly improves the simplicity and efficiency of the unlocking operation. In an emergency or when the screen window needs to be opened and closed frequently, the design of the linkage lock can respond quickly, avoiding the tedious unlocking process in the traditional independent lock buckle design, thereby improving the user experience. The number and layout of the locks 1 can be adjusted according to actual needs to adapt to screen windows of different sizes and shapes, and has strong flexibility.

[0043] In a specific embodiment, the lock housing 11 includes a lock body 111, a lock cover 112 and an assembly portion 113. The lock body 111 has a lock slot 1111 with an opening 1112 on one side. The direction of the opening 1112 is kept horizontal with the first direction. The lock slot 1111 is used to accommodate the lock tongue 12. The lock tongue 12 includes a sliding block 121, a locking portion 122 and an unlocking portion 123. The sliding block 121 is slidably arranged in the lock slot 1111. The lock cover 112 is covered with the opening 1112. The assembly portion 113 is arranged away from the lock body 111. On one side of the opening 1112, the lock cover 112 is provided with a limiting hole 1121 for partially extending the lock tongue 12. The locking portion 122 is located on one side of the sliding block 121 and is used to extend from the limiting hole 1121. The unlocking portion 123 is located on the other side of the sliding block 121. The unlocking member 14 is assembled with the unlocking portion 123. That is, the locking portion 122 and the unlocking portion 123 are respectively provided on two side surfaces of the sliding block 121 in the first direction. The lock cover 112 and the assembly portion 113 are respectively provided on two side surfaces of the lock body 111 in the first direction. With this configuration, the lock body 111, the lock cover 112 and the assembly portion 113 together constitute the complete structure of the lock housing 11, providing the necessary support and guarantee for the extension and retraction of the lock tongue 12 and the fixation of the lock 1, thereby achieving efficient and convenient unlocking operation. By operating the unlocking portion 123, the sliding block 121 and the locking portion 122 can be driven to slide, thereby achieving unlocking, and the user can easily and quickly complete the unlocking operation. It should be noted that the projected area of the sliding block 121 on the lock cover 112 needs to be larger than the projected area of the locking portion 122 on the lock cover 112, and the projected area of the locking portion 122 on the lock cover 112 is not larger than the area of the limiting hole 1121, so that the locking portion 122 can extend more smoothly into the lock slot 1111, and the sliding block 121 will not disengage from the lock slot 1111. In this embodiment 1, the unlocking portion 123 is a structure that protrudes from the sliding block 121 in the first direction, and the unlocking portion 123 is located in the center of the sliding block 121. A reset member 13 is provided on both sides of the unlocking portion 123, and the reset member 13 abuts against the lock slot 1111 and the sliding block 121 respectively. The unlocking portion 123 can limit the deformation range and direction of the reset member 13. The two reset members 13 can maintain the stability of the overall contraction of the lock tongue 12.

[0044] In some embodiments, in order to make it easier for the driving member 3 on the linkage member 2 to drive the unlocking member 14 to move, the unlocking member 14 is designed as a rod-shaped body, and the unlocking member 14 is arranged along a third direction, and the third direction is perpendicular to the first direction and the second direction. The unlocking member 14 is passed through the unlocking portion 123 along the third direction, and both ends of the unlocking member 14 protrude from the unlocking portion 123. Slide rails 1113 arranged along the first direction are provided on both sides of the lock body 111, and the two ends of the unlocking member 14 are respectively slidably arranged in the slide rails 1113 on both sides of the lock body 111. It should be noted that the slide rail 1113 can be a slide groove arranged along the first direction, or a waist-shaped hole 31 arranged along the first direction. Thus, the unlocking member 14 cooperates with the slide rails 1113 on both sides of the lock body 111, ensuring that the unlocking member 14 can be stably installed in the slide rails 1113 and maintain close contact with the slide rails 1113 during the sliding process, reducing shaking and friction; the user can drive the unlocking member 14 to slide along the slide rails 1113 by operating the linkage member 2, thereby synchronously driving the unlocking of all lock tongues 12.

[0045] It should be noted that the driving member 3 and the linkage member 2 can be integrally connected, fixedly connected, or detachably connected. In a specific embodiment, multiple driving members 3 and linkage members 2 are provided, and the two are staggered and connected. Driving members 3 and linkage members 2 of different lengths can be replaced according to the number and position of the locks 1. In a specific embodiment, a linkage member 2 can also be provided, and multiple driving members 3 are assembled on the linkage member 2. The linkage member 2 is provided with multiple holes for assembling the driving members 3, so that the position of the driving member 3 on the linkage member 2 can be adjusted according to the number and position of the locks 1.

[0046] In some embodiments, in order to ensure that the linkage member 2 can stably displace along the second direction, a through-hole 1114 is provided on the lock body 111 along the second direction, and the driving member 3 is provided through the through-hole 1114, so that when the linkage member 2 moves along the second direction, the lock 1 can limit the movement of the driving member 3. It should be noted that the position and size of the through-hole 1114 must match the driving member 3 to ensure that the driving member 3 can stably penetrate the through-hole 1114 and maintain close contact with the lock body 111 during movement. It should be noted that the size of the through-hole 1114 also needs to determine the connection method between the driving member 3 and the linkage member 2. When the driving member 3 and the linkage member 2 are fixed together, the through-hole 1114 must ensure that both can pass through.

[0047] In some embodiments, to facilitate user operation of the linkage member 2, an operating portion 21 is provided on the linkage member 2. The operating portion 21 is used to cause the linkage member 2 to move in the second direction. The primary function of the operating portion 21 is to transmit the user's operating force to the linkage member 2, thereby driving the unlocking member 14 to move synchronously. In this first embodiment, the operating portion 21 is a hole-like structure located on the linkage member 2. The user can pull the hole-like structure with their finger to cause the linkage member 2 to move. In other embodiments, the operating portion 21 may be a pull cord, a pull ring, or a block-like structure.

[0048] To facilitate the overall assembly of the lock 1, in some embodiments, an assembly plate 4 is further provided. The assembly plate 4 has a sliding groove 41, within which multiple locks 1 slide. A locking member 5 is provided between the sliding groove 41 and the lock 1. The locking member 5 allows the required number of locks 1 to be assembled in the sliding groove 41 in advance, facilitating overall assembly within the door frame of the screen system. The assembly plate 4 serves as a support and mounting platform for the locks 1, allowing the locks 1 to be neatly arranged and slide along the sliding groove 41, allowing the number and position of the locks 1 to be adjusted according to actual needs to accommodate screens of different sizes and shapes.

[0049] Optionally, the locking member 5 is arranged toward one bottom edge of the sliding groove 41, so that the locking member 5 acts on both edges of the sliding groove 41 at the same time. The locking member 5 is preferably a screw, which enables the locking member 5 to act more directly on the contact surface between the lock 1 and the sliding groove 41 during installation, thereby increasing the contact area between the locking member 5 and the sliding groove 41, thereby improving the stability and reliability of the locking, and at the same time reducing the depth of the groove and reducing the space occupied by the assembly.

[0050] The present invention also relates to a screen window system, comprising a first screen window frame 6, a second screen window frame 7, a screen window window body 8 and a linkage lock, wherein the lock 1 is assembled on the first screen window frame 6 along a first direction, the screen window window body 8 is hinged to the second screen window frame 7, and the screen window window body 8 is provided with a locking groove 81 for engaging with a lock tongue 12 on a side facing the lock 1. When the user operates the linkage member 2 of the linkage lock, the driving member 3 can drive the unlocking member 14 to move, thereby driving the lock tongue 12 to move in a direction away from the locking groove 81 to reach an unlocked state. At this time, the screen window body 8 can be rotated to open. The overall structure is compact and easy to operate, and the screen window window 8 can be effectively prevented from being accidentally opened in the unlocked state.

[0051] When the lock 1 is assembled on the assembly plate 4, the assembly plate 4 can be inserted into the first screen frame 6 as a whole. Specifically, the edge of the first screen frame 6 facing the locking groove 81 is provided with a recessed portion 61 for accommodating the lock 1 or the assembly plate 4, and the side of the recessed portion 61 opposite to the locking groove 81 is provided with an assembly groove 611 for assembling the lock 1 or the assembly plate 4, and the side of the recessed portion 61 adjacent to the locking groove 81 is provided with a clamping edge 612 for clamping the lock 1. 1 is provided with a snap-fit edge 1115 corresponding to the clamping edge 612. Thus, through the coordinated action of the recessed portion 61, the assembly groove 611 and the clamping edge 612, the lock 1 can be firmly installed on the first screen frame 6 and form an effective locking relationship with the locking groove 81 on the screen window body 8. At the same time, before the lock 1 is fixed, the lock 1 can slide along the recessed portion 61 or the assembly plate 4, and at the same time, it is limited by the clamping edge 612 to prevent the lock 1 from falling in a natural state, which makes assembly more convenient and the quantity and position adjustment more flexible.

[0052] In order to facilitate the closing and locking operation of the screen window 8, a sliding surface 124 is provided on one side of the lock tongue 12. The sliding surface 124 is an inclined surface or a curved surface. When the screen window 8 is closed, the lock tongue 12 can be triggered to rebound, and then it is locked in the locking groove 81 to complete the automatic locking. When unlocking is required, the user controls the linkage member 2 and the driving member 3 to move downward by operating the operating part 21, and the unlocking member 14 of all the locks 1 is passively slid upward along the inclined waist-shaped hole 31, thereby causing the unlocking member 14 to slide along the slide rail 1113 toward the driving member 3. At this time, the reset member 13 is compressed, and the lock tongue 12 completely enters the lock groove 1111, thereby disengaging the lock tongue 12 from the locking groove 81 to complete the unlocking.

[0053] In summary, the interlocking lock and screen window system provided by the present invention has the following technical effects:

[0054] 1. Through the design of the linkage member 2, the user only needs to operate once to simultaneously activate the unlocking members 14 of multiple locks 1, so that all lock tongues 12 are unlocked simultaneously. This greatly reduces the number of actions required by the user, especially when there are many locking points, and significantly improves the efficiency and convenience of the unlocking operation;

[0055] 2. Since the interlocking lock can drive multiple locks 1 simultaneously, it ensures that all locking points of the screen window 8 are tightly locked when closed, thereby improving the sealing and stability of the screen window. This is especially important in environments where better sealing is required, such as areas with strong winds or indoor spaces that need to be kept out of mosquitoes.

[0056] 3. The design of the interlocking lock and screen system is highly flexible. The number and layout of the locks 1 can be adjusted according to actual needs to accommodate screens of different sizes and shapes. This design enables the system to be widely used in various residential and architectural environments.

[0057] 4. In the unlocked state, the interlocking lock can effectively prevent the screen window 8 from being accidentally opened, thereby improving the safety of the family. This design is particularly important for families with children or pets.

[0058] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
