Description

Technical Field

[0001] The utility model relates to the technical field of window openers, in particular to an electric single-screw window opener. Background Art

[0002] An electric window opener is a device that uses an electric drive mechanism to automatically open and close windows. It is widely used in building automation, smart homes, industrial ventilation and other fields, including screw window openers, chain window openers and folding window openers. Among them, the screw electric window opener performs well in many applications, especially in situations where stable and strong push-pull forces are required.

[0003] Screw-type window openers generally use a motor to drive the internal screw to extend or shorten to open or close the window. The opening and closing speed of screw-type electric window openers is usually slow, and the screw drive takes a long time to complete a full stroke of movement. The friction between the screw and the nut will cause wear, and regular maintenance and lubrication are required to keep it in good operating condition. Long-term use may cause serious wear of the screw or nut, thereby affecting the transmission efficiency and accuracy. At the same time, in the event of a sudden power outage, the drive motor is powered off, and it may be difficult to manually close the window due to the integrity of the screw window opener or the damping of the drive motor, resulting in losses. Therefore, we designed an electric single-screw window opener. Utility Model Content

[0004] The utility model aims to provide an electric single-screw window opener, which can respond quickly to complete the window opening and closing action. At the same time, in the case of power failure, the clutch component design can be conveniently rotated to manually close or open, thereby preventing accidents or losses and solving the problems raised in the background technology.

[0006] A disc is arranged in the rotating ring, and the outer side of the disc is fixedly connected to the inner wall of the rotating ring; a rotating tube is arranged in the main pipeline and fixedly connected to the disc; a telescopic rod is inserted in the rotating tube, a threaded hole is arranged on the outer side of the rotating tube, a limiting rod is fixedly connected to the outer side of the telescopic rod, and one end of the limiting rod away from the telescopic rod passes through the threaded hole; a limiting groove is arranged on the inner wall of the main pipeline, and one end of the limiting rod away from the telescopic rod is slidably connected in the limiting groove; a clutch assembly is arranged in the secondary pipeline.

[0007] Through the above technical solution, when the disc rotates, the rotating tube will be driven to rotate. Since the limit rod is limited by the limit groove, the rotating tube with a threaded hole on the rotating tube will drive the limit rod to move in the limit groove, that is, the telescopic rod can move linearly to extend and shorten, thereby realizing the window opening and closing action. At the same time, the rotating ring can be operated from the outside to drive the disc to rotate, thereby manually opening and closing the window, so as to adapt to different usage scenarios, improve its practicality and safety, and solve the problems raised in the background technology.

[0008] Preferably, the clutch assembly comprises: a fixed disk, a rotating rod, a special-shaped block, a strip hole, a toggle rod and a bearing, the disk is fixedly connected to the fixed disk on the side away from the rotating tube, the output end of the driving motor is fixedly connected to the rotating rod through a coupling, the outer side of the rotating rod is movably connected to the special-shaped block, the outer side of the auxiliary pipeline is provided with a strip hole, the toggle rod is inserted in the strip hole, the toggle rod extends into the auxiliary pipeline and is movably connected to the outer side of the special-shaped block through a bearing, the fixed disk is provided with a special-shaped groove adapted to the special-shaped block, and the special-shaped block is inserted in the special-shaped groove.

[0009] Through the above technical scheme, when the driving motor of the present application is energized, the special-shaped block is clamped in the special-shaped groove in the fixed disk, so that when the driving motor rotates, the disc is driven to rotate to electrically open and close the window; when the driving motor is powered off, the toggle rod is moved to disengage the special-shaped block from the special-shaped groove, that is, the special-shaped block is disengaged from the fixed disk, and the rotating ring can be manually operated from the outside to open and close the window, wherein the special-shaped block is movably connected to the outside of the rotating rod, that is, the rotating rod can normally drive the special-shaped block to rotate, and the special-shaped block can normally move up and down on the outside of the rotating rod, so that the special-shaped block can be driven to move by the toggle rod, and at the same time, the toggle rod is movably connected to the special-shaped block through the bearing, that is, the special-shaped block will not affect the position of the toggle rod during rotation, and will not be limited by the toggle rod, thereby ensuring the overall operation.

[0010] Preferably, the length of the special-shaped block is greater than the depth of the special-shaped groove, and the length of the strip-shaped hole is adapted to the length of the special-shaped block.

[0011] Through the above technical solution, when the toggle rod drives the special-shaped block to move so that a part of the special-shaped block is inserted into the special-shaped groove in the fixed plate for limiting, the toggle rod will not affect the insertion effect.

[0013] Through the above technical scheme, when the rotation of the rotating tube drives the change of the threaded hole, the limit rod will drive the movement of the limit rod in the limit groove. The cooperation between the limit rod and the limit groove can not only play a limiting effect, but also reduce the friction between the limit rod and the limit groove, thereby ensuring the smoothness of movement.

[0015] Preferably, one end of the telescopic rod away from the disc extends to the outside of the main pipe and is provided with a connecting piece, and an anti-slip layer is provided on the outside of the rotating ring.

[0016] Through the above technical solution, the telescopic rod of the present application is installed and connected with the mounting piece on the window through the top connecting piece, thereby ensuring stability during use. The anti-skid layer on the outside of the rotating ring can enhance friction to prevent hand slippage.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. The electric single-screw window opener, through the cooperation of the main body, disc, rotating tube, telescopic rod, threaded hole, limit rod and limit groove, makes the rotating tube driven by the disc when it rotates, that is, the limit rod moves in the limit groove so that the telescopic rod can be extended and shortened to complete the window opening and closing action. At the same time, the rotating ring can be operated from the outside to manually open and close the window, ensuring the practicality and safety of the window opener.

[0019] 2. The electric single-screw window opener is designed with a clutch assembly. When the drive motor is powered on, the special-shaped block is clamped in the special-shaped groove in the fixed disk, so that the drive motor rotates to drive the disk to rotate for electric window opening and closing. When the drive motor is powered off, the toggle rod is moved to separate the special-shaped block from the fixed disk. At this time, the rotation of the disk is not damped by the drive motor, and the rotating ring can be operated from the outside to quickly open and close the window, thereby avoiding losses to the greatest extent.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: an electric single-screw window opener, comprising a main body 1, the main body 1 comprising a main pipe 101, a secondary pipe 102, a rotating ring 103 and a connecting rod 104, the rotating ring 103 is arranged between the main pipe 101 and the secondary pipe 102, and the rotating ring 103 is movably connected to the main pipe 101 and the secondary pipe 102, the outer sides of the main pipe 101 and the secondary pipe 102 are fixedly connected by the connecting rod 104, and a driving motor 2 is fixedly installed on the side of the secondary pipe 102 away from the main pipe 101;

[0027] A disc 3 is arranged in the rotating ring 103, and the outer side of the disc 3 is fixedly connected to the inner wall of the rotating ring 103. A rotating tube 4 is arranged in the main pipeline 101 and is fixedly connected to the disc 3. A telescopic rod 5 is inserted in the rotating tube 4.

A clutch assembly 9 is arranged in the secondary pipeline 102.

[0028] Through the above technical scheme, when the disc 3 rotates, the rotating tube 4 will be driven to rotate. Since the limiting rod 7 is limited by the limiting groove 8, the rotating tube 4 with the threaded hole 6 on the rotating tube 4 will drive the limiting rod 7 to move in the limiting groove 8, that is, the telescopic rod 5 can move linearly to extend and shorten, thereby realizing the window opening and closing action. At the same time, the rotating ring 103 can be operated from the outside to drive the disc 3 to rotate, thereby manually opening and closing the window, so as to adapt to different usage scenarios, improve its practicality and safety, and solve the problems raised in the background technology.

[0029] The clutch assembly 9 includes: a fixed disk 901, a rotating rod 902, a special-shaped block 903, a strip hole 904, a toggle rod 905 and a bearing 906. The fixed disk 901 is fixedly connected to the side of the disk 3 away from the rotating tube 4. The output end of the drive motor 2 is fixedly connected to the rotating rod 902 through a coupling. The outer side of the rotating rod 902 is movably connected to the special-shaped block 903. A strip hole 904 is opened on the outer side of the auxiliary pipeline 102. The toggle rod 905 is inserted in the strip hole 904. The toggle rod 905 extends into the auxiliary pipeline 102 and is movably connected to the outer side of the special-shaped block 903 through the bearing 906. A special-shaped groove adapted to the special-shaped block 903 is opened in the fixed disk 901, and the special-shaped block 903 is inserted in the special-shaped groove.

[0030] Through the above technical scheme, when the driving motor 2 is powered on, the special-shaped block 903 is clamped in the special-shaped groove in the fixed disk 901, so that when the driving motor 2 rotates, the disc 3 is driven to rotate to electrically open and close the window. When the driving motor 2 is powered off, the toggle rod 905 is moved to disengage the special-shaped block 903 from the special-shaped groove, that is, the special-shaped block 903 is disengaged from the fixed disk 901, and the rotating ring 103 can be manually operated from the outside to open and close the window, wherein the special-shaped block 903 is movably connected to the outer side of the rotating rod 902, that is, the rotating rod 902 can normally drive the special-shaped block 903 to rotate, and the special-shaped block 903 can move up and down normally on the outer side of the rotating rod 902, so that the special-shaped block 903 can be driven to move by the toggle rod 905, and at the same time, the toggle rod 905 is movably connected to the special-shaped block 903 through the bearing 906, that is, the special-shaped block 903 will not affect the position of the toggle rod 905 during rotation, and will not be limited by the toggle rod 905, thereby ensuring the overall operation.

[0031] The length of the special-shaped block 903 is greater than the depth of the special-shaped groove, and the length of the strip hole 904 is adapted to the length of the special-shaped block 903 .

[0032] Through the above technical solution, when the toggle rod 905 drives the special-shaped block 903 to move so that a part of the special-shaped block 903 is inserted into the special-shaped groove in the fixed disk 901 for limiting, the toggle rod 905 will not affect the insertion effect.

[0033] The diameter of the limiting rod 7 is consistent with the width of the limiting groove 8 , and the shape of the threaded hole 6 is matched with the shape of the limiting rod 7 .

[0034] Through the above technical scheme, in the present application, when the rotation of the rotating tube 4 drives the change of the threaded hole 6, it will drive the limiting rod 7 to move in the limiting groove 8. The cooperation between the limiting rod 7 and the limiting groove 8 can, on the one hand, have a limiting effect, and on the other hand, can reduce the friction between the limiting rod 7 and the limiting groove 8, thereby ensuring the smoothness of the movement.

[0035] The outer side of the rotating ring 103 contacts the inner wall of the main pipe 101 , and the length of the rotating ring 103 is consistent with the length of the main pipe 101 .

[0036] One end of the telescopic rod 5 away from the disc 3 extends to the outside of the main pipe 101 and is provided with a connecting piece, and the outside of the rotating ring 103 is provided with an anti-slip layer.

[0037] Through the above technical solution, the telescopic rod 5 of the present application is installed and connected with the mounting piece on the window through the top connecting piece, thereby ensuring stability during use. The anti-skid layer on the outside of the rotating ring 103 can enhance friction to prevent hand slippage.

[0038] When the electric single-screw window opener is working, the special-shaped block 903 is clamped in the special-shaped groove in the fixed disk 901. At this time, when the drive motor 2 is started to rotate, the disc 3 and the rotating tube 4 are driven to rotate. The threaded hole 6 follows the rotation of the rotating tube 4 to drive the limit rod 7 to move in the limit groove 8, that is, the telescopic rod 5 can move in a straight line to extend and shorten, thereby realizing the window opening and closing action. When the drive motor 2 is powered off, the toggle rod 905 is moved to disengage the special-shaped block 903 from the special-shaped groove, that is, the special-shaped block 903 is disengaged from the fixed disk 901. At this time, the rotating ring 103 can be manually operated from the outside to open and close the window, so as to ensure that the manual operation will not be affected by the damping of the drive motor 2, making the window opening and closing action easier and faster.
