Description

Technical Field

[0001] The utility model relates to the technical field of window openers, in particular to a novel anti-jamming chain-type electric window opener. Background Art

[0002] A chain-operated window opener is a common electric window-opening device that opens and closes windows by retracting and extending a chain. Its compact structure allows it to maintain a wide range of travel and opening angles, even without changing its appearance during operation. This significantly improves the visual quality of the window. Chain-operated window openers are commonly used on top-hung, tilt-in, tilt-out, casement, center-hung, sliding, and skylight windows.

[0003] The current chain-type window openers have more or less some problems when in use. Most of the current window openers use guide rails to guide the chain to slide. This will easily cause the chain to stretch when it gets stuck, which is not conducive to better sliding of the chain. When the chain needs to be maintained, the chain needs to be pulled out from the guide rail little by little, which is not only inefficient but also inconvenient to re-install the chain in the guide rail, which easily increases the workload of the operator.

[0004] Therefore, a novel anti-stuck chain type electric window opener is invented to solve the above problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] When the existing window opener is in use, a guide rail is generally used to guide the chain to slide. This will easily cause the chain to be stretched when it gets stuck, causing the chain to be stuck in the guide rail, which is not conducive to better sliding of the chain. When the chain needs to be maintained, the chain needs to be pulled out from the guide rail little by little, which is not only inefficient but also inconvenient to reinstall the chain in the guide rail, which easily increases the workload of the operator. Therefore, this embodiment is specially invented to solve the above problems.

[0026] like Figure 1-Figure 5 As shown, a new type of anti-stuck chain-type electric window opener according to an embodiment of the present invention includes a shell 1, in which two sprockets 2 distributed along the length direction are rotatably connected, and a chain 3 is meshed between the two sprockets 2. Two clamping plates 4 are slidably connected in the shell 1, and each clamping plate 4 is U-shaped. The two clamping plates 4 can slide relative to or back to each other, and the chain 3 is located between the two clamping plates 4. Each clamping plate 4 can contact the side wall of the chain 3, and a guide groove 5 with the same shape as the clamping plate 4 is provided on the clamping plate 4, which can guide the movement of the chain 3.

[0027] A longitudinally extending support plate 6 is slidably connected in the shell 1, and guide grooves 7 are provided on both sides of the longitudinal direction of the support plate 6. Each clamping plate 4 is fixedly connected to an insertion rod 8 at one end close to the support plate 6, and each insertion rod 8 can be extended into the corresponding guide groove 7. A vertically extending screw rod 9 is rotatably connected in the shell 1, and the screw rod 9 passes through the support plate 6 and is threadedly connected to the support plate 6. The two guide grooves 7 form an eight-shaped shape, and one end of the screw rod 9 is coaxially fixedly connected to a rotating cap 20. Each clamping plate 4 is fixedly connected to a longitudinally extending telescopic rod 10 at one end away from the support plate 6, and the free end of each telescopic rod 10 is fixedly connected to the inner wall of the shell 1.

[0028] Two rotating shafts 11 corresponding to the sprocket 2 are rotatably connected in the shell 1, and each rotating shaft 11 is coaxially fixedly connected to the corresponding sprocket 2. One end of each rotating shaft 11 is coaxially fixedly connected to a pulley 12, and the two pulleys 12 are connected by a belt 13. A worm gear 14 is coaxially fixedly connected to the rotating shaft 11 near the support plate 6. A motor 15 is provided in the shell 1, and the output end of the motor 15 is coaxially fixedly connected to a worm 16 engaged with the worm gear 14. An outlet plate 17 is provided on the shell 1, and the free end of the chain 3 extends out of the outlet plate 17 and is fixedly connected to a mounting frame 18. Both lateral ends of the shell 1 are fixedly connected to a fixing frame 19. The chain 3 includes multiple chain plates 301 and chain shafts 302, and the multiple chain plates 301 and the multiple chain shafts 302 are hinged in sequence.

[0029] When in use, first install the free end of the chain 3 on the edge of the window sash through the mounting bracket 18, then install the housing 1 on the windowsill through the fixing bracket 19, connect the motor 15 to the external power supply, and when opening the window, start the motor 15, and the motor 15 rotates forward to drive the worm wheel 14 to rotate through the worm 16, so that the worm wheel 14 drives one of the rotating shafts 11 to rotate. Under the action of the pulley 12 and the belt 13, the two rotating shafts 11 drive the two sprockets 2 to rotate forward synchronously, so that the two sprockets 2 drive the chain 3 to extend from the outlet plate 17 to the housing 1, so that the chain 3 pushes the window sash to open, wherein the chain 3 is composed of multiple chain plates 301 and chain shafts. 302 is hingedly connected, so that when the chain 3 moves in the shell 1, the chain shaft 302 of the chain 3 can be inserted into the guide groove 5 of the clamping plate 4 on the corresponding side, so that the chain 3 can slide better along the clamping plate 4, which not only can better guide the movement of the chain 3, but also can constrain the state of the chain 3 through the clamping plate 4, and at the same time can avoid the problem of irregular movement when the chain 3 is loose. After the window is opened, the motor 15 is turned off, and the worm gear 14 and worm 16 structure has a certain self-locking property, which can make the sprocket 2 and the rotating shaft 11 in a stable position, so that the chain 3 can support the stable state of the window sash being opened.

[0030] When closing the window, start the motor 15 to reverse it, and then repeat the above movement in the reverse direction, so that the chain 3 can be collected into the housing 1 through the outlet plate 17, and the chain 3 is again located between the two clamping plates 4 to complete the window closing action. When the chain 3 needs to be maintained or repaired, first rotate the screw rod 9 through the rotating cap 20, and the screw rod 9 rotates to drive the support plate 6 to slide along the housing 1. Since the two guide grooves 5 form an eight-shaped shape, the support plate 6 drives the two clamping plates 4 to move back to each other along the housing 1 through the guide grooves 5 and the insertion rod 8. The two clamping plates 4 drive the telescopic rods 10 on the corresponding sides to retract. At this time, the multiple chain shafts 302 on the chain 3 are no longer inserted into the guide grooves 5, so that the two clamping plates 4 no longer clamp the chain 3 After the chain 3 is installed again, the chain 3 is engaged between the two sprockets 2 and the chain 3 is in a taut state. Then, the screw rod 9 is rotated in the opposite direction by the rotating cap 20. The screw rod 9 drives the support plate 6 to slide in the opposite direction along the shell 1, so that the support plate 6 drives the two clamping plates 4 to slide relative to each other along the shell 1 through the guide groove 7 and the insertion rod 8. The clamping plate 4 drives the telescopic rod 10 on the corresponding side to extend. At this time, the two ends of the chain shaft 302 on the chain 3 are gradually inserted into the guide groove 5 of the corresponding clamping plate 4, guiding and constraining the position of the chain 3, so that the chain 3 can move better in the shell 1 and better open and close the window.

[0031] In summary, by setting the clamping plate 4 and the guide groove 5, not only can the chain shaft 302 on the chain 3 be guided and constrained by the guide groove 5, thereby reducing the situation where the chain 3 is stretched, but also avoiding the situation where the chain 3 is stuck, it is convenient to keep the chain 3 in a taut state, and facilitate the stable movement of the chain 3 under the action of the sprocket 2, thereby improving the window opening and closing effect, and the two clamping plates 4 that can slide back to back or relative to each other can make the chain shaft 302 on the chain 3 no longer located in the guide groove 5 on the clamping plate 4, so that the clamping plate 4 no longer constrains and guides the chain 3, thereby facilitating the removal of the chain 3 from the sprocket 2 for maintenance, and also facilitating the reinstallation of the chain 3 on the sprocket 2 for use, further improving the movement effect of the chain 3, and facilitating the maintenance and installation of the chain 3, and the operation is simple and convenient.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
