Description

Technical Field

[0001] This utility model relates to a window opening machine, specifically a ring chain window opening machine. Background Technology

[0002] In existing technologies, window openers are widely used in various building scenarios to improve the convenience and efficiency of window operation. For example, the electric window opener and opening mechanism disclosed in CN107013122A uses a single-chain mode to realize the opening and closing of windows. However, with the continuous advancement of technology and the increasing diversification of application needs, higher requirements are being placed on the performance of window openers.

[0003] While single-chain window openers meet basic window operation needs to a certain extent, their force distribution has limitations. Because only one side of the chain bears the tension, the single-chain system may be insufficient when dealing with heavy or specially made windows, potentially leading to chain breakage or damage to the window opener. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a ring chain window opener.

[0005] The technical solution of this utility model is: a ring chain window opener, which includes a window opener body and a chain. The window opener body includes a shell, and a chain storage bin is fixed inside 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 ring-shaped. 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. 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 passes around the steering wheel.

[0006] Furthermore, the first driving device is a motor, which is fixed at the lower left end of the storage chain bin, and the output shaft of the motor extends into the storage chain 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 to the outside of the right end of the housing. The piston rod end of the right end of the cylinder is fixedly connected to the connecting seat. The stop rod extends forward and backward and is fixed on the connecting seat. The long shaft extends vertically and its upper end is fixedly connected to the second sprocket. The stop wheel is fixed to the lower end of the long shaft. The stop rod and the stop wheel are engaged.

[0008] Furthermore, a locking block protrudes from the outer side of the front end of the stop lever, and the outer side of the stop wheel has a slot for the locking block to engage.

[0009] Furthermore, the right rear end of the outer casing is provided with a through-hole, through which the stop bar passes.

[0010] The beneficial effects of using the ring chain window opener provided by this utility model are: the ring chain design allows both sides of the chain of the window opener to bear force, thereby effectively improving the overall tensile strength. Compared with the traditional single chain mode, the load-bearing capacity is significantly improved. Attached Figure Description

Detailed Implementation

[0018] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0019] like Figure 1 — Figure 6As shown, the circular chain window opener includes a main body 100 and a chain 200. The main body 100 includes a housing 1, inside which a chain storage bin 2 is fixed. 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 circular. 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 its rotation. A locking mechanism for locking or unlocking the second sprocket 4 is installed at the right end of the housing 1. The circular chain window opener also includes a guide wheel 6 installed on the window sash (not shown), around which the chain 200 passes. The main body 100 is fixed to the window frame (not shown). There are two guide wheels 6, installed at the left and right ends of the window sash respectively. The chain storage bin 2 has notches at its left and right front ends for the chain 200 to pass through.

[0020] like Figure 2 As shown, the first driving device is a motor 5, which is fixed to the lower left end of the chain storage bin 2. 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 housed inside the outer casing 1.

[0021] like Figure 2 , Figure 5 As shown, the locking mechanism includes a cylinder 7, a connecting seat 8, a stop rod 9, a stop wheel 10, and a long shaft 11. The cylinder 7 is fixed to the right end of the outer casing 1, and the piston rod end of the right end of the cylinder 7 is fixedly connected to the connecting seat 8. The stop rod 9 extends forward and backward and is fixedly fixed to the connecting seat 8. The long shaft 11 extends vertically, and its upper end is fixedly connected to the second sprocket 4. The stop wheel 10 is fixed to the lower end of the long shaft 11, and the stop rod 9 and the stop wheel 10 are engaged. A locking block 91 protrudes from the outer side of the front end of the stop rod 9, and the outer side of the stop wheel 10 has a slot 101 for the locking block 91 to engage. When the cylinder 7 is working, it can drive the connecting seat 8 and the stop rod 9 to move left and right, so the locking block 91 can engage in the slot 101 or move out of the slot 101.

[0022] The outer casing 1 is fixed with a cover 12 that covers the cylinder 7.

[0023] like Figure 6 As shown, in order to facilitate the movement of the stop bar 9, the rear right end of the housing 1 is provided with a through-hole 1.1, through which the stop bar 9 passes.

[0024] Electric opening and closing mode: When motor 5 rotates forward, it drives the first sprocket 3 to rotate, releasing the chain 200 stored in the chain storage bin 2, opening the window sash (bottom-hung windows can be opened by gravity, and top-hung windows can be opened with the help of a strut). After the chain 200 is released, cylinder 7 controls the stop lever 9 to move to the left, causing the stop lever 9's locking block 91 to engage with the locking groove 101 of the stop wheel 10, locking the stop wheel 10 and locking the second sprocket 4 as well. The motor 5 stops powering due to overload protection, and the window is opened. To close the window, motor 5 reverses, the second sprocket 4 remains locked, and the chain 200 is retracted. When the chain storage bin 2 is full of chain 200 or the window sash is closed, the motor 5 stops powering due to overload protection, and the window is closed.

[0025] Manual opening mode: Cylinder 7 is ventilated, causing the stop lever 9 to disengage from the stop wheel 10. At this time, the second sprocket 4 is unrestricted and in a free state, and the chain 200 can extend from the right end of the chain storage bin 2 (the lower window can be opened by gravity, and the upper window can be opened with the help of the strut).

[0026] This utility model adopts a ring chain 200 design, which allows both sides of the chain 200 of the window opener to bear force, thereby effectively improving the overall tensile strength. Compared with the traditional single chain mode, the load-bearing capacity is significantly improved.

[0027] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
