Description

Technical Field

[0001] The invention relates to a window opening machine, in particular to an annular chain window opening machine. Background Art

[0002] In the prior art, window openers have been widely used in various building scenes to improve the convenience and efficiency of window operation. For example, the electric window opener and window opening mechanism disclosed in CN107013122A adopt a single chain mode to open and close the window. However, with the continuous advancement of technology and the increasing diversification of application requirements, higher requirements are placed on the performance of window openers.

[0003] Although the single-chain mode window opener meets the basic window operation requirements to a certain extent, its force-bearing method has certain limitations. Since only one side of the chain bears the tension, when facing a window of heavy weight or special material, the single-chain mode may seem powerless, and may even cause the chain to break or the window opener to be damaged. Summary of the invention

[0004] In view of the above-mentioned defects of the prior art, the object of the present invention is to provide an annular chain window opening machine.

[0005] The technical solution of the present invention is: an annular chain window opener, which includes a window opener body and a chain. The window opener body includes a shell, a chain storage bin is fixed in the shell, a first sprocket and a second sprocket are respectively installed at the left and right ends of the chain storage bin, the chain is annular, and the chain storage bin has a chain storage groove for accommodating the chain, and the chain is wound around the first sprocket and the second sprocket, the first sprocket is connected to a first driving device for driving the first sprocket to rotate, and a locking mechanism for locking or unlocking the second sprocket is installed at the right end of the shell; it also includes a steering wheel installed on the window sash, and the chain bypasses the steering wheel.

[0006] Furthermore, the first driving device is a motor, which is fixed at the lower left end of the chain storage bin, and the output shaft of the motor extends into the chain storage bin and is connected to the first sprocket.

[0007] Furthermore, the locking mechanism includes a cylinder, a connecting seat, a stop rod, a stop wheel and a long shaft. The cylinder is fixed outside the right end of the outer shell, the piston rod end of the right end of the cylinder is fixedly connected to the connecting seat, the stop rod is fixed on the connecting seat extending forward and backward, the long shaft extends up and down and its upper end is fixedly connected to the second sprocket, the stop wheel is fixed to the lower end of the long shaft, and the stop rod is clamped with the stop wheel.

[0008] Furthermore, a clamping block is protruded from the outer side of the front end of the blocking rod, and a clamping groove for the clamping block to be clamped into is provided on the outer side of the blocking wheel.

[0009] Furthermore, a sliding hole which penetrates inside and outside is provided at the right rear end of the shell, and the blocking rod passes through the sliding hole.

[0010] The beneficial effect of applying the ring chain window opener provided by the present invention is that the ring chain design allows the chains on both sides of the window opener to be stressed, thereby effectively improving the overall tension. Compared with the traditional single chain mode, the load-bearing capacity is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] In order to more intuitively and completely understand the technical solution of the present invention, a non-limiting feature description is now provided in conjunction with the accompanying drawings of the present invention as follows: like Figure 1 — Figure 6 As shown, the ring chain window opener includes a window opener body 100 and a chain 200. The window opener body 100 includes a housing 1, a chain storage bin 2 is fixed in the housing 1, and a first sprocket 3 and a second sprocket 4 are respectively installed at the left and right ends of the chain storage bin 2. The chain 200 is annular, and the chain storage bin 2 has a chain storage groove 21 for accommodating the chain 200, and the chain 200 is wound around the first sprocket 3 and the second sprocket 4. The first sprocket 3 is connected to a first driving device for driving the first sprocket 3 to rotate, and a locking mechanism for locking or unlocking the second sprocket 4 is installed at the right end of the housing 1; the ring chain window opener also includes a steering wheel 6 installed on the window sash (not shown in the figure), and the chain 200 bypasses the steering wheel 6. The window opener body 100 is fixed on the window frame (not shown in the figure). There are two steering wheels 6, and the two steering wheels 6 are respectively installed at the left and right ends of the window sash. The left front end and the right front end of the chain storage bin 2 both have a gap for the chain 200 to pass through.

[0014] like Figure 2As shown, the first driving device is a motor 5, which is fixed at the lower left end of the chain storage bin 2, and the output shaft of the motor 5 extends into the chain storage bin 2 and is connected to the first sprocket 3. The motor 5 is accommodated in the housing 1.

[0015] like Figure 2 , Figure 5 As shown, the locking mechanism includes a cylinder 7, a connecting seat 8, a blocking rod 9, a blocking wheel 10 and a long shaft 11. The cylinder 7 is fixed outside the right end of the housing 1. The piston rod end of the right end of the cylinder 7 is fixedly connected to the connecting seat 8. The blocking rod 9 is fixed on the connecting seat 8 to extend forward and backward. The long shaft 11 extends up and down and its upper end is fixedly connected to the second sprocket 4. The blocking wheel 10 is fixed to the lower end of the long shaft 11, and the blocking rod 9 is engaged with the blocking wheel 10. A block 91 is convexly provided on the outer side of the front end of the blocking rod 9, and a slot 101 is provided on the outer side of the blocking wheel 10 for the block 91 to be engaged. When the cylinder 7 is working, it can drive the connecting seat 8 and the blocking rod 9 to move left and right, so the block 91 can be engaged in the slot 101 or removed from the slot 101.

[0016] A cover shell 12 covering the cylinder 7 is fixed outside the housing 1 .

[0017] like Figure 6 As shown, in order to facilitate the movement of the blocking rod 9, a sliding hole 1.1 penetrating from inside to outside is provided at the right rear end of the housing 1, and the blocking rod 9 passes through the sliding hole 1.1.

[0018] Electric opening and closing mode: When the motor 5 rotates forward, the motor 5 drives the first sprocket 3 to rotate, and the chain 200 stored in the chain storage bin 2 is released, and the window sash opens (the lower-hung window can be opened by gravity, and the upper-hung window can be opened by the support rod). After the chain 200 is released, the cylinder 7 controls the blocking rod 9 to move to the left, so that the block 91 of the blocking rod 9 is stuck in the slot 101 of the blocking wheel 10, and the blocking wheel 10 is locked, so that the second sprocket 4 is also locked, and the motor 5 stops being powered due to overload protection, and the window is opened. To close the window, the motor 5 reverses, the second sprocket 4 remains locked, and the chain 200 is recovered. When the chain 200 in the chain storage bin 2 is fully collected or the window sash is closed, the motor 5 stops being powered due to overload protection, and the window is closed.

[0019] Manual opening mode: the cylinder 7 is ventilated to disengage the blocking rod 9 from the blocking wheel 10. At this time, the second sprocket 4 is not restricted and is in a free state, and the chain 200 can extend from the right end of the chain storage bin 2 (the lower hanging window can be opened by gravity, and the upper hanging window can be opened with the help of a support rod).

[0020] The present invention adopts the design of the ring chain 200, so that the chains 200 on both sides of the window opener can be stressed, thereby effectively improving the overall pulling force. Compared with the traditional single chain mode, the load-bearing capacity is significantly improved.

[0021] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the contents of the specification and drawings of the present invention should be included in the patent protection scope of the present invention.
