Description

Technical Field

[0001] This utility model relates to the field of window handle technology, specifically to a rotatable window handle structure. Background Technology

[0002] Handles are devices installed on door and window sashes that serve both to open and close the door and to secure them. They are mostly made of materials such as aluminum alloy, copper, stainless steel, plexiglass, and plastic. They come in various forms and sizes. In addition to meeting the requirements of comfortable feel and reasonable force distribution, they also have a decorative effect. Therefore, the materials and shapes are selected from finished products or designed separately according to the architectural design requirements.

[0003] Chinese patent CN219910348U discloses a door and window handle and a door / window. It has a pressing groove on the surface of the handle base, the surface of the pressing groove is in contact with the surface of the rotating shaft, the side end surface of the rotating shaft is fixedly connected to the side end surface of the limiting block, and the side end surface of the limiting block is fixedly connected to the side end surface of the rotating square shaft. To open the window, you need to hold the handle and press it backward to make the rotating square shaft engage with the square shaft locking block. Children have less strength and it is not easy for them to press the handle, which reduces the probability of safety accidents.

[0004] Although the above solution uses a spring to elastically separate the rotating shaft from the fixed block to prevent children from opening and closing the handle, the square shaft block does not have a limit after the rotating shaft is pulled out of it. The limiting structure connected to it will shift under the action of gravity, thus affecting the sealing effect of the handle on the window.

[0005] Therefore, this utility model provides a window rotatable handle structure to solve the above problems. Utility Model Content

[0006] In order to overcome the defects of the prior art, this utility model provides a window rotatable handle structure to solve the problem that the spring can be used to elastically separate the rotating shaft from the fixed block to prevent children from opening and closing the handle. However, since the square shaft is not limited after it is pulled out from the square shaft locking block, the limiting structure connected to it will be offset under the action of gravity, which will affect the sealing effect of the handle on the window.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A rotatable window handle structure includes a fixed base, a mounting block, a handle, and a second spring. The fixed base has a sliding groove, the mounting block has a rotating groove, the handle has a movable connecting component, the mounting block is rotatably connected to a linkage shaft, one end of the linkage shaft is fixedly connected to a linkage box, a movable plate is slidably connected inside the linkage box, one end of the movable plate is provided with a linkage component, and the handle drives the linkage box to rotate through the connecting component and the linkage component. The other end of the movable plate is fixedly connected to a push-out block, the linkage box has a through hole adapted to the push-out block, the fixed base is provided with an elastic support component, and the telescopic end of the elastic support component is inserted into the through hole.

[0009] Preferably, the connecting assembly includes a slider slidably connected in a groove, one end of the slider being fixedly connected to a square insert rod, the other end of the slider being fixedly connected to a connecting rod, the end of the connecting rod away from the slider passing through the groove and being fixedly connected to the handle, and the connecting rod being slidably connected to the fixed base.

[0010] Preferably, one end of the second spring abuts against the slider, and the other end of the second spring abuts against the inner wall of the rotating groove.

[0011] Preferably, the linkage component includes a linkage block fixedly connected to the movable plate, one end of the linkage block passing through the linkage box and extending to the outside of the linkage box, and the linkage block having a square groove that matches the square plug rod.

[0012] Preferably, the elastic support assembly includes a control box fixedly connected to a fixed base, a support plate slidably connected inside the control box, a limit rod fixedly connected to the support plate, one end of the limit rod passing through the control box and extending to the outside of the control box, and the limit rod matching the through hole.

[0013] Preferably, the control box is provided with a first spring, one end of which abuts against the mounting block and the other end of which abuts against the support plate.

[0014] Preferably, the mounting base has two mounting slots.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Through the coordinated setup of the linkage component and the elastic support component, after the square insert rod is inserted into the square slot, the linkage block drives the moving plate to move, so that the top block pushes the telescopic end of the elastic support component out of the perforation, releasing the limit on the linkage box, effectively preventing the limit structure from shifting due to gravity, thereby enhancing the sealing effect of the window.

[0017] 2. By utilizing the elastic support of the second spring, the slider is kept on the inner wall of one side of the slide when not in use. This requires children to apply a certain amount of force to move the handle, thereby reducing the risk of children accidentally opening the window and improving safety. Attached Figure Description

Detailed Implementation

[0023] The following will refer to the attached reference. Figures 1 to 4 The various embodiments of this utility model will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0024] A rotatable window handle structure includes a fixed base 1, a mounting block 2, a handle 5, and a second spring 21. The fixed base 1 has two mounting grooves 3 and a sliding groove 7. The mounting block 2 has a rotating groove 9.

[0025] The fixed seat 1 and the mounting block 2 can be connected together by welding, bolts or other means, and the sliding groove 7 and the rotating groove 9 are in an aligned state, that is, the sliding groove 7 and the rotating groove 9 are connected. The fixed seat 1 can be fixed by installing bolts in the mounting groove 3.

[0026] The handle 5 is provided with a movable connecting component, which includes a slider 8 that is slidably connected in the slide groove 7. One end of the slider 8 is fixedly connected to a square insert rod 10, and the other end of the slider 8 is fixedly connected to a connecting rod 4. The end of the connecting rod 4 away from the slider 8 passes through the slide groove 7 and is fixedly connected to the handle 5. The connecting rod 4 is slidably connected to the fixed base 1.

[0027] The handle 5 can drive the slider 8 to move within the slide groove 7 via the connecting rod 4, and the handle 5 can also drive the slider 8 to rotate within the slide groove 7 via the connecting rod 4.

[0028] One end of the second spring 21 abuts against the slider 8, and the other end of the second spring 21 abuts against the inner wall of the rotating groove 9. The second spring 21 supports the slider 8 by its own elasticity, so that the slider 8 is on one side of the inner wall of the groove 7 when it is not in use.

[0029] A linkage shaft 6 is rotatably connected to the mounting block 2. A linkage box 11 is fixedly connected to one end of the linkage shaft 6. A movable plate 14 is slidably connected inside the linkage box 11. A linkage component is provided at one end of the movable plate 14. The handle 5 drives the linkage box 11 to rotate through the connecting component and the linkage component.

[0030] The linkage component includes a linkage block 12 fixedly connected to the movable plate 14. One end of the linkage block 12 passes through the linkage box 11 and extends to the outside of the linkage box 11. A square groove 13 matching the square plug rod 10 is provided on the linkage block 12.

[0031] When driving the linkage box 11 to rotate, the handle 5 needs to move the connecting rod 4 and insert the square rod 10 on the slider 8 into the square groove 13. After rotating the handle 5, the square rod 10 drives the linkage block 12 to rotate in the square groove 13. This causes the linkage block 12 to drive the linkage shaft 6 to rotate through the linkage box 11, and the lock on the linkage shaft 6 to close or open the window.

[0032] The other end of the movable plate 14 is fixedly connected to the ejector block 15. The linkage box 11 has a through hole 16 that matches the ejector block 15. The fixed base 1 is provided with an elastic support component, and the telescopic end of the elastic support component is inserted into the through hole 16.

[0033] When the linkage shaft 6 needs to be rotated, the square insert rod 10 will be inserted into the square slot 13 and then drive the moving plate 14 to move through the linkage block 12. The moving plate 14 will push the telescopic end of the elastic support component out of the through hole 16 through the ejector block 15, thereby releasing the limit on the linkage box 11.

[0034] In this embodiment, the elastic support assembly includes a control box 17 fixedly connected to the fixed base 1. A support plate 18 is slidably connected inside the control box 17. A limit rod 20 is fixedly connected to the support plate 18. One end of the limit rod 20 passes through the control box 17 and extends to the outside of the control box 17. The limit rod 20 matches the through hole 16. The limit rod 20 is the telescopic end. When the limit rod 20 is inserted into the through hole 16, it can limit the linkage box 11.

[0035] The control box 17 is equipped with a first spring 19. One end of the first spring 19 abuts against the mounting block 2, and the other end of the first spring 19 abuts against the support plate 18. The support plate 18 is supported by the elasticity of the first spring 19 itself, so as to ensure the stability of the limit rod 20 inserted into the through hole 16.
