Description

Technical Field

[0001] The utility model relates to a double-shaped chain window opening device, belonging to the technical field of chain transmission. Background Art

[0002] Top-hung windows, commonly known as outward-opening windows, are a type of window that has hinges installed on the upper side of the window and opens inward or outward. It is a new form developed on the basis of casement windows, with a unique opening method and multiple advantages. Top-hung windows can be opened horizontally like casement windows, or pushed open from the top and hung in the air. Due to their unique opening method and advantages, top-hung windows are widely used in various architectural scenes, such as high-rise buildings, public places, commercial places, and kitchens, bathrooms and other areas in homes.

[0003] When top-hung windows are installed at higher places, they are often equipped with automatic opening and closing hinge devices for opening and closing the top-hung windows. However, during the movement of such hinges, the chain plates will rotate relative to each other, which will cause greater wear. Therefore, the hinges used for opening and closing often need to be repaired and replaced. Each replacement requires the entire opening and closing device to be disassembled, which is more troublesome. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a double-shaped chain window opening device, which solves the problem of inconvenient maintenance of the hinge device for automatic opening and closing of the top-hung window in the prior art.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical solution: comprising a pair of special-shaped chain components that can move synchronously and mesh with each other, and two symmetrically arranged chain frames,

[0006] The two special-shaped chain components are in meshing state to form a support chain extending in the direction of movement, and the two special-shaped chain components are in a separated state to be accommodated in the two chain frames respectively.

[0007] The special-shaped chain assembly includes an inner link and an outer link,

[0008] The inner cavity of the chain frame is symmetrically provided with linking slide rails, the connecting slide rails include a central slide rail and a side slide rail, and the outer end of the chain frame is detachably connected with a U-shaped steering member.

[0009] By adopting the above technical solution, during the process of the special-shaped chain components meshing with each other and extending in the outward movement direction, the two meshed special-shaped chain components push the casement window. After the casement window is pushed open, it can remain in the open state under the support of the special-shaped chain components. When it is necessary to close the casement window, the control driver drives the sprocket to rotate, driving the special-shaped chain components to move into the chain frame respectively, and the two special-shaped chain components are separated from each other. During this process, the outward-extended special-shaped chain components contract inward, driving the casement window to close inward. When the casement window is completely closed, the ends of the special-shaped chain components are still connected to the casement window, which can play a continuous locking role for the casement window.

[0010] The present utility model is further configured as: both the inner link and the outer link include link plates and shaft rods.

[0011] A pair of connection holes are provided on the link plates. Two link plates are rotatably connected by the shaft rod at different plate spacings to respectively form the outer link and the inner link. The plate spacing of the outer link is greater than that of the inner link.

[0012] One of the connection holes of multiple said outer links and inner links is connected end to end by sharing a shaft rod to form a special-shaped chain component. A rotatable rolling ring is sleeved on the shaft rod.

[0013] By adopting the above technical solution, sharing a shaft rod to connect the heads and tails of multiple links greatly simplifies the assembly process of the chain and reduces the production cost. At the same time, this design also makes the maintenance and replacement of parts of the chain easier and faster. Through the setting of the rolling ring, the frictional loss generated when the hinge performs the receiving movement is reduced.

[0014] The present utility model is further configured as: the link plate is provided with a hook-shaped structure. The hook-shaped structures of the link plates on the two special-shaped chain components face the same direction. When the special-shaped chain components are meshing, the hook-shaped structures on the link plates of different special-shaped chain components mesh and engage with each other.

[0015] By adopting the above technical solution, the two special-shaped chain components are meshed with each other through the hook-shaped structure. When the hook-shaped structures on the two meshed link plates are meshing, the end portions of the hook-shaped structures of each other are inserted into the inner ring of the hook-shaped structure to achieve mutual meshing.

[0016] The present utility model is further configured as: a turning inner support is provided at the center of the U-shaped turning member. The two ends of the U-shaped turning member are respectively inserted into the two side sliding rails of the chain frame.

[0017] By adopting the above technical solution, during the accommodation process of the special-shaped chain assembly, as the chain frame moves to the outermost end of the chain frame, under the guiding action of the turning inner support and the U-shaped turning member, the movement direction can be changed, so that the length of the special-shaped chain assembly that the entire chain frame can accommodate is greatly increased.

[0018] The U-shaped turning member can be quickly disassembled, which greatly reduces the maintenance difficulty of the entire device. By directly opening and closing the end cover to disassemble the U-shaped turning member, the special-shaped chain assembly can be directly repaired.

[0019] The present utility model is further configured as: a pushing member is fixedly connected to one end where the two special-shaped chain assemblies are permanently meshed, and the pushing member is used to push or pull the casement window after being connected to the casement window.

[0020] By adopting the above technical solution, the pushing member is connected to one end where the two special-shaped chain assemblies are permanently meshed, which can ensure the stability of the special-shaped chain assembly during movement. And by connecting the special-shaped chain assembly to the casement window through the pushing member, it is avoided that the chain links of the special-shaped chain assembly directly contact the casement window, making it more convenient to install and disassemble the device.

[0021] The present utility model is further configured as: a sprocket support and a guide support are respectively arranged on the left and right sides of the meshing center line of the two special-shaped chain assemblies. A driving sprocket meshing with one of the special-shaped chain assemblies is arranged at the center of the sprocket support, and the driving sprocket is connected to the driving component through a transmission shaft. Guide rounded corners are arranged on the two side edges of the guide support that are in contact with the special-shaped chain assembly.

[0022] By adopting the above technical solution, the sprocket support is equipped with a driving sprocket that meshes with the special-shaped chain assembly and drives the special-shaped chain assembly to move. At the same time, the sprocket support plays the same guiding role as the guide support and can assist the special-shaped chain assembly in turning.

[0023] The present utility model is further configured as: including a protective housing, the protective housing encloses the remaining components of the device in the inner cavity, and an extension opening for the special-shaped chain assembly to extend outward after meshing is arranged in the middle area.

[0024] By adopting the above technical solution, the protective housing frames most of the components in the device into the inner cavity, making the entire device more beautiful, and can effectively prevent environmental factors such as dust from damaging the device, and can effectively protect the internal structure of the device. Since lubricant inevitably needs to be added for lubrication when the entire device is running, which further reduces the frictional loss, it is necessary to isolate the inside of the device from the outside as much as possible to prevent dust from adhering and causing the lubricant to fail.

[0025] The present utility model is further configured as: a guide plate is arranged at the corner where the special-shaped chain assemblies are meshed.

[0026] By adopting the above technical solution, the guide plate enables the hinge to quickly turn during the accommodation process.

[0027] The beneficial effect of the present utility model is that through the chain frame and the U-shaped turning member provided at the end of the chain frame, the window opening device can be quickly repaired without complete disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0035] As Figure 1As shown in the figure, the double-shaped chain window opening device includes a protective housing 3. The protective housing 3 encloses the rest of the device components in its inner cavity. The protective housing 3 frames most of the components of the device into the inner cavity, making the whole device more beautiful and effectively preventing environmental factors such as dust from damaging the device, and can effectively protect the internal structure of the device. Since it is inevitable to add lubricant for lubrication when the whole device is running, which further reduces the frictional loss, it is necessary to isolate the inside of the device from the outside as much as possible to prevent the lubricant from failing due to dust adhesion.

[0036] An extension port for the extended outward engagement of the shaped chain assembly 1 is provided in the middle area of the protective housing 3.

[0037] Among them, the protective housing 3 is made of aluminum alloy material and is formed by folding and flipping. It is integrally strip-shaped, and the left and right ends are fixed by bolts to the opening and closing end covers 14.

[0038] When maintenance or replacement of internal components is required, only need to open the opening and closing end covers 14 at both ends to quickly repair the shaped chain assembly 1 inside the protective housing 3.

[0039] As Figure 2 shown in the figure, the double-shaped chain window opening device includes a pair of shaped chain assemblies 1 that can move synchronously and mesh with each other, and two symmetrically arranged chain frames 2. The chain frames 2 are integrally formed aluminum profiles. When the two shaped chain assemblies 1 are in the meshed state, they form a support chain extending in the moving direction. When the two shaped chain assemblies 1 are in the separated state, they are respectively received in the two chain frames 2.

[0040] When the casement window (not shown) needs to be opened, by controlling the shaped chain assembly 1 to extend outward, the casement window is pushed to flip outward to open the casement window. At the same time, the meshed shaped chain assembly 1 plays a supporting role for the casement window after it is opened.

[0041] When the casement window needs to be closed, by controlling the shaped chain assembly 1 to move into the chain frame 2, the two meshed shaped chain assemblies 1 are separated from each other and move into the left and right chain frames 2 respectively.

[0042] As Figure 3 shown in the figure, chain link slide rails 201 are symmetrically arranged in the inner cavity of the chain frame 2. The connecting slide rails include a central slide rail 2012 and side slide rails 2011.

[0043] Among them, the side slide rails 2011 and the central slide rail 2012 enclose two channel cavities for the movement of the shaped chain assembly 1.

[0044] As Figure 5 shown in the figure, both the inner link 101 and the outer link 102 include chain plates 4 and shaft rods 5.

[0045] A pair of connecting holes 401 are provided on the link plate 4. Two link plates 4 are rotatably connected by the shaft rod 5 at different plate spacings to form an outer link 102 and an inner link 101 respectively. The plate spacing of the outer link 102 is greater than that of the inner link 101. One of the connecting holes 401 of multiple outer links 102 and inner links 101 is connected end to end through sharing a shaft rod 5 to form a special-shaped chain assembly 1. A rotatable rolling ring 6 is sleeved on the shaft rod 5. The setting of the rolling ring 6 reduces the frictional loss generated when the hinge performs the receiving movement.

[0046] As Figure 2 shown, detachable U-shaped turning parts 7 are provided on two relatively far side edges of the two chain frames 2, and a turning inner support 9 is provided at the center of the U-shaped turning part 7. The two ends of the U-shaped turning part 7 are respectively inserted into the side slide rails 2011 on the two side edges of the chain frame 2. The left chain frame 2 in the figure is not shown, and the U-shaped turning part 7 on the side and the protective end cover are in a disassembled state.

[0047] As Figure 2 shown, the right chain frame 2 in the figure, the U-shaped turning part 7 and the protective end cover are in an assembled state.

[0048] Among them, the U-shaped turning part 7 is of an overall U-shaped structure, and the U-shaped ends extend outwards to form clamping blocks and are inserted into the side slide rails 2011 on the side edges of the chain frame 2. Side protection plates 15 are installed on both sides of the U-shaped turning part 7 through bolts. The two side protection plates 15 are fixedly connected by a connecting rod 18 in cooperation with bolts, and the U-shaped turning part 7 is clamped in the middle.

[0049] A center support plate is provided at the center of the U-shaped turning part 7 through the side protection plates 15.

[0050] During the receiving process of the special-shaped chain assembly 1, when the chain frame 2 moves to the outermost end of the chain frame 2, under the guiding action of the turning inner support 9 and the U-shaped turning part 7, the movement direction can be changed, so that the length of the special-shaped chain assembly 1 that the entire chain frame 2 can accommodate is greatly increased.

[0051] As Figure 4 shown, a pusher 10 is fixedly connected to one end where two special-shaped chain assemblies 1 are permanently engaged. The pusher 10 is connected to one end where two special-shaped chain assemblies 1 are permanently engaged. The pusher 10 is used to push or pull the casement window after being connected to the casement window.

[0052] In this embodiment, the pusher 10 is made of a metal material by stamping. Bolt holes capable of being connected to the casement window (not shown) are provided on the pusher 10 and are fixed to the casement window through bolts.

[0053] On the left and right sides of the meshing center line of the two special-shaped chain assemblies 1, a sprocket support 12 and a guide support 11 are respectively arranged. A driving sprocket 13 meshing with one of the special-shaped chain assemblies 1 is arranged at the center of the sprocket support 12.

[0054] During the rotation of the driving sprocket, the whole special-shaped chain assembly 1 is driven by the engagement of the teeth of the driving sprocket. When the special-shaped chain assembly 1 moves, it drags the other special-shaped chain assembly 1 to move and meshes with it.

[0055] The driving sprocket 13 is connected to the driving component 8 through a transmission shaft. The driving component 8 consists of a set of reduction gearboxes and a motor. The motor is meshed with a gear in the reduction gearbox through a threaded rod to achieve transmission.

[0056] Guide round corners are arranged on both sides of the guide support 11 that fits with the special-shaped chain assembly 1. The arc radian of the chamfered round corner is the same as the turning radian of the special-shaped chain assembly 1. The sprocket support 12 plays the same guiding role as the guide support 11 and can assist the special-shaped chain assembly 1 in turning.

[0057] The link plate 4 is provided with a hook-shaped structure 402. The hook-shaped structures 402 of the link plates 4 on the two special-shaped chain assemblies 1 face the same direction. When the special-shaped chain assemblies 1 are meshing, the hook-shaped structures 402 on the link plates 4 of different special-shaped chain assemblies 1 are meshed and clamped with each other.

[0058] The two special-shaped chain assemblies 1 are meshed with each other through the hook-shaped structure 402. When the hook-shaped structures 402 on the two meshed link plates 4 are meshing, the ends of their hook-shaped structures 402 are inserted into the inner ring of the hook-shaped structure 402 to achieve mutual meshing.

[0059] The mutual meshing and clamping of the hook-shaped structures 402 can provide a more stable connection and reduce the risk of chain derailment during transmission. The design of the hook-shaped structure 402 enables the chain to be accurately positioned during meshing, ensuring the accuracy and reliability of transmission. The meshing method of the hook-shaped structure 402 can reduce the impact during chain meshing, thereby reducing the noise and vibration during transmission. Stable meshing and low impact contribute to improving the smoothness of transmission and making the equipment operate more smoothly and reliably.

[0060] The design of the guide plate 17 makes the transmission path of the chain at the corner smoother, reducing the energy loss caused by poor path. To a certain extent, it reduces the resistance of the chain during transmission, thereby improving the transmission efficiency. The plug-in design of the guide plate 17 and the chain frame 2 makes the installation process simpler and faster, reducing the installation difficulty and cost. The design of the guide plate 17 makes it more convenient to disassemble and install relevant components when the chain assembly needs to be maintained or replaced.

[0061] Working principle: The special-shaped chain assembly 1 extends outwards or is housed in the chain frame 2 under the drive of the drive sprocket.

[0062] During the extension of the special-shaped chain assembly 1, the chain plates 4 on the two special-shaped chain assemblies 1 mesh with each other and are clamped to each other through the hook-shaped structures 402 on the chain plates 4.

[0063] Among them, the chain plates 4 on the inner chain links 101 mesh with each other in pairs, and the chain plates 4 on the outer chain links 102 mesh with each other in pairs. After the two special-shaped chain assemblies 1 mesh to form a support chain, the inner chain links 101 are clamped between two chain plates 4 on the outer chain links 102.

[0064] In addition, the U-shaped guide members provided on both sides of the chain frame 2 can be disassembled at any time, which enables direct maintenance of the special-shaped chain assembly 1 in the chain frame 2 only by disassembling the U-shaped guide members when components in the whole device are damaged and need to be repaired or replaced.

[0065] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope claimed by the present utility model. The scope claimed by the present utility model is defined by the appended claims and their equivalents.
