Description

Technical Field

[0001] This utility model belongs to the field of door and window technology, and in particular relates to a locking mechanism and a door / window. Background Technology

[0002] As a crucial component of building structures, doors and windows primarily function to divide space, regulate ventilation and lighting, and ensure security. With advancements in materials technology, doors and windows have evolved from traditional wood and metal to utilize new materials such as aluminum alloys, PVC, and composite materials, combining lightweight design with high strength, while also emphasizing energy efficiency, sound insulation, and weather resistance. In recent years, the rise of smart home technology has driven the intelligent transformation of doors and windows, with electric control, sensor integration, and remote management functions making them key components of smart buildings.

[0003] As the core of security, the locking mechanism of doors and windows is mainly based on mechanical locks. There are two common types of locking mechanisms on indoor floor-to-ceiling windows and windows. One type uses a vertical push to open and close the window, and then slides the window horizontally. This method can ensure the flatness of the operating end, but it is not very convenient because it requires two operations, one vertical and one horizontal. Moreover, the window must be completely closed to lock. If it is not completely closed, it is necessary to operate back and forth. The other type uses a rotating opening and closing mechanism, which also requires additional horizontal auxiliary parts (anti-slip plate, concave / convex block) to push. It is not very convenient to operate, and the locking mechanism may also be subject to impact and bumping at the overlapping position of the inner and outer windows.

[0004] Secondly, the inward-facing keyhole structure can accumulate debris and dust, increasing the risk of jamming and resulting in poor protection.

[0005] To address the aforementioned problems, this application proposes a locking mechanism and a door / window. Utility Model Content

[0006] The purpose of this utility model is to provide a locking mechanism and a door / window that solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a locking mechanism, comprising a first plate and a second plate. The second plate has an integrated baffle on its side near the first plate. A plug is fixed to one end of the second plate near the first plate, and a vertical lock hole is formed in the plug. The first plate has a locking plate inside that engages with the lock hole. A transition plate is connected to the upper end of the locking plate via a locking spring. A socket inside the first plate engages with the plug and also contains a spring-loaded sliding block. When the block is normally pushed to the left, the movable rib, under the action of a transmission component, pushes the transition plate downwards and stores the locking spring. At this time, after the plug pushes the block inwards, the locking plate can engage with the lock hole under the action of the locking spring. When the movable rib is pushed to the right, during the upward movement of the transition plate, the locking plate is pulled upwards by a pull rod and a pull block, disengaging from the lock hole. The direction of the movable rib's movement is consistent with the opening and closing direction of the second plate.

[0009] Furthermore, the transmission component includes a horizontal toothed plate fixed to the movable rib and located inside the first plate, and a driving gear rotatably disposed inside the first plate. The horizontal toothed plate meshes with the driving gear, the driving gear is coaxially fixed with the transition gear, the transition gear meshes with the driven gear, and a vertical toothed plate meshing with the driven gear is fixed on the top of the adapter plate.

[0010] Furthermore, the upper end of the locking plate is provided with a positioning plate, the pull rod extends downward and passes through the positioning plate and is fixed to the pull block, the side of the adapter plate is provided with a guide groove, and the inside of the first plate is fixed with a guide rail that slides with the guide groove.

[0011] Furthermore, a sinkhole is formed in the first plate, the movable rib slides in the sinkhole, a protective plate that fits against the sinkhole is fixed to the side of the movable rib, and a fixing rib is also fixed in the sinkhole.

[0012] Furthermore, the rear end of the blocking block is fixed with a guide rod that passes through the rear end of the socket and a protective spring that abuts against the guide rod and the outside of the rear end of the socket. The blocking block is blocked at the bottom of the locking plate by the protective spring, and the front end of the blocking block is flush with the end of the first plate near the second plate.

[0013] This utility model also provides a door or window, including the locking structure described above.

[0014] This utility model has the following beneficial effects:

[0015] This utility model features a horizontally sliding movable rib that works in conjunction with a transmission component, a locking plate, and a locking spring. It can automatically store force using the horizontal thrust of closing the window. When the first plate and the second plate are in contact, the locking plate automatically locks itself through the stored locking spring, improving ease of operation.

[0016] This utility model can protect the socket when the door or window is opened by setting a blocking block, and at the same time support the locking plate to store force, so that the whole locking mechanism can work together tightly, which has both reliability and protection.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please see Figures 1-7 As shown, this utility model is a locking mechanism, including a first plate 1 and a second plate 2. The second plate 2 has an integrated baffle 21 on its side near the first plate 1. A plug 22 is fixed to one end of the second plate 2 near the first plate 1, and a vertical locking hole 221 is formed in the plug 22. The first plate 1 has a locking plate 3 inside that inserts into the locking hole 221. A connecting plate 4 is connected to the upper end of the locking plate 3 via a locking spring 5. A socket 11 inside the first plate 1 engages with the plug 22 and also has an elastic sliding mechanism inside. When the movable block 8 is in its normal state, it pushes the movable rib 6 to the left. Under the action of the transmission component 7, the movable rib 6 pushes the adapter plate 4 down and stores the locking spring 5. At this time, after the insert block 22 pushes the block 8 inward, the locking plate 3 can be inserted and locked with the lock hole 221 under the action of the locking spring 5. When the movable rib 6 is pushed to the right, during the upward movement of the adapter plate 4, the locking plate 3 is pulled upward by the pull rod 41 and the pull block 42 and disengaged from the lock hole 221. The direction of the movable rib 6 is consistent with the opening and closing direction of the second plate 2.

[0031] The transmission component 7 includes a horizontal toothed plate 71 fixed to the movable rib 6 and located inside the first plate 1, and a drive gear 72 rotatably disposed inside the first plate 1. The horizontal toothed plate 71 meshes with the drive gear 72, the drive gear 72 is coaxially fixed with the transition gear 73, the transition gear 73 meshes with the driven gear 74, and a vertical toothed plate 75 is fixed on the top of the adapter plate 4 and meshes with the driven gear 74. In this embodiment, the transition gear 73 is larger than the driven gear 74, which can ensure the lifting height of the locking plate 3 and the adapter plate 4 while shortening the sliding stroke of the movable rib 6.

[0032] The upper end of the locking plate 3 is provided with a positioning plate, which is used to position the locking plate 3 after it moves downward, ensuring that the locking plate 3 is in the best engagement position. The pull rod 41 extends downward and passes through the positioning plate before being fixed to the pull block 42. In this state, the pull block 42 acts as a barb. When the adapter plate 4 moves the pull rod 41 and the pull block 42 downward, it will not directly drive the locking plate 3. Only when the locking spring 5 returns to its normal state and the adapter plate 4 continues to move upward can the locking plate 3 be moved upward. This setting can not affect the storage of the locking spring 5, and at the same time ensure the stable disengagement of the locking plate 3 from the lock hole 221, resulting in higher structural reliability. The side of the adapter plate 4 is provided with a guide groove 43. The first plate 1 is fixed with a guide rail 13 that slides with the guide groove 43. The cooperation between the guide groove 43 and the guide rail 13 ensures that the locking plate 3 and the adapter plate 4 move stably in the vertical direction in the first plate 1.

[0033] Among them, a sinkhole 12 is formed in plate 1, and the movable rib 6 slides in the sinkhole 12. A protective plate 61 that fits into the sinkhole 12 is fixed on the side of the movable rib 6. A fixing rib 14 is also fixed in the sinkhole 12. There is an operating space on the right side of the fixing rib 14. When the movable rib 6 moves to the leftmost side, there is also an operating space between it and the sinkhole 12 to avoid contact with the sinkhole 12 and affect the ease of use.

[0034] The block 8 has a guide rod 81 that passes through the rear end of the socket 11 and a protective spring 9 that abuts against the guide rod 81 and the outside of the rear end of the socket 11. The block 8 is blocked at the bottom of the locking plate 3 by the protective spring 9, which is used to lock the stored force of the spring 5. At the same time, the insertion action is linked with the closing action of the first plate 1 to improve convenience. The upper and lower ends of the block 8 are provided with positioning strips that cooperate with the positioning groove inside the socket 11. When the protective spring 9 pushes the block 8 outward, its front end is flush with the end of the socket 11 and the first plate 1 near the second plate 2, ensuring reliable protection and preventing garbage from entering the socket 11 and causing jamming or jamming.

[0035] The socket 11 has a through hole for the locking plate 3 to be inserted through. The through hole is divided into upper and lower parts. The upper part is used as a guide for the lifting and lowering of the locking plate 3, and the lower part is used to strengthen the connection stability. When the locking plate 3 is inserted with the upper and lower ends at the same time, it effectively prevents the insertion point from loosening and deforming.

[0036] This utility model also provides a door and window, including the above-mentioned locking structure, wherein the first plate 1 is a movable door on the door and window, and the second plate 2 can be movable or fixed. The locking mechanism combines convenient opening and closing of the door and window with stable locking.

[0037] It is understood that this utility model adopts a horizontally sliding movable rib linkage transmission component, which, together with the locking plate and locking spring, forms an automatic power-accumulating locking mechanism. It is completed by the horizontal thrust when the window is closed. After the first plate and the second plate are attached, the spring is triggered to automatically lock, making the operation efficient and convenient. The blocking block set at the same time has a dual function: it is a protective socket when the door and window are opened and provides support for the power-accumulating of the locking plate, ensuring that the mechanism operates tightly and reliably, and achieving a dual improvement in protection and stability.

[0038] One specific application of this embodiment is as follows: Figures 1-3 The diagram shows the open state. When locking is required, the movable rib 6 is moved towards the end of the second plate 2 in the socket 11. After the movable rib 6 moves in the socket 11, it drives the horizontal toothed plate 71 to mesh with the driving gear 72. The driving gear 72 drives the transition gear 73 to mesh with the driven gear 74. The driven gear 74 meshes with the vertical toothed plate 75, thereby driving the adapter plate 4 to move down. Since the bottom of the locking plate 3 is against the blocking block 8 at this time, the locking spring 5 stores force when the adapter plate 4 moves down. After the movable rib 6 is moved to the bottom, it continues to apply force, causing the first plate 1 to slide towards the second plate 2. The plug 22 contacts the blocking block 8 and pushes it into the socket 11. The protective spring 9 is stretched. After the plug 22 is fully inserted into the socket 11, the locking plate 3 corresponds to the lock hole 221 and is locked under the action of the locking spring 5.

[0039] When disengagement is required, first press the movable rib 6 and the fixed rib 14, and slide the movable rib 6 in the opposite direction to the end. The movable rib 6 drives the adapter plate 4 to move upward through the transmission component 7. During the upward movement of the adapter plate 4, the locking plate 3 is pulled upward through the pull rod 41 and the pull block 42 until it is disengaged from the lock hole 221. Then, with the help of the movable rib 6 and the fixed rib 14, the first plate 1 is pushed away from the second plate 2, and it can be opened. At the same time, when the plug 22 is withdrawn from the inside of the socket 11, the protective spring 9 pushes the blocking block 8 to the front end of the socket 11 and forms a block at the bottom of the locking plate 3.
