Technical Field
[0001] This utility model belongs to the field of handle technology, specifically relating to a handle with a rotation locking mechanism. Background Technology
[0002] Handles are devices installed on door and window sashes, serving both an opening and closing locking function. When the door or window is closed, the handle, along with other accessories, securely locks the opening door or window sash to the fixed frame, thus fixing the relative positions of the inner and outer frames. Handles are commonly made of materials such as aluminum alloy, copper, stainless steel, plexiglass, and plastic. They come in various forms and sizes. Besides meeting the requirements of comfortable handling and reasonable force distribution, they also have a decorative effect; therefore, the materials and shapes are selected from pre-made products or custom-designed according to the architectural design requirements.
[0003] Traditional window handles can only be used to lock the window sash, but cannot lock the handle after rotation. Anyone can operate it to open the window sash, which not only poses the risk of accidental opening of the handle, but also poses a safety hazard, especially if a child opens the window without permission, which may cause an accident. In this regard, this application proposes a handle with a rotation locking mechanism. Utility Model Content
[0004] The purpose of this invention is to provide a handle with a rotary locking mechanism in order to solve the above-mentioned problems.
[0005] This utility model achieves the above objectives through the following technical solutions:
[0006] A handle with a rotary locking mechanism includes a handle rod, a handle seat rotatably disposed on one side of the handle rod, and a rotary locking mechanism disposed between the handle rod and the handle seat. The handle rod has a plurality of limiting holes, a tooth is fixedly disposed on one side of the handle rod, the tooth is rotatably connected to the handle seat, and a plurality of first arc-shaped holes communicating with the limiting holes are fixedly disposed on the outer wall of one end of the tooth.
[0007] The rotary locking mechanism includes a cover plate rotatably disposed on the side of the handle seat near the handle rod, a rotating ring fixedly disposed in the cover plate, and a second arc-shaped hole opened in the rotating ring and communicating with the limiting hole.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0024] Example
[0025] like Figure 1-6 As shown, a handle with a rotary locking mechanism includes a handle rod 1, a handle seat 2 and a rotary locking mechanism. The handle seat 2 is rotatably disposed on one side of the handle rod 1. The handle seat 2 can be installed on doors and windows using screws or other components. The handle rod 1 can rotate on the handle seat 2.
[0026] like Figure 2-4 As shown, the handle rod 1 has several limiting holes 22 inside, and a tooth 3 is fixedly provided on one side of the handle rod 1. The tooth 3 is rotatably connected to the handle seat 2. Several first arc-shaped holes 31 communicating with the limiting holes 22 are fixedly provided on the outer wall of one end of the tooth 3. A connecting post 11 is fixedly provided between one side of the handle rod 1 and the inside of the tooth 3. The connecting post 11 can connect the handle rod 1 and the tooth 3, so that the tooth 3 will rotate when the handle rod 1 rotates.
[0027] like Figure 2-5 As shown, a fixing groove 21 is provided in the handle seat 2. The tooth 3 is rotatably connected in the fixing groove 21 of the handle seat 2. Two sets of damping seats 33 are fixedly provided in the fixing groove 21 of the handle seat 2. A first steel ball 34 is movably provided in the damping seat 33. Several tooth holes 32 are provided on the outer side wall of the tooth 3. One end of the first steel ball 34 is inserted into the tooth hole 32. The handle seat 2 can support and fix the damping seat 33 through the fixing groove 21. Through the insertion of the first steel ball 34 in the damping seat 33 into the corresponding tooth hole 32 after the tooth 3 rotates, the handle rod 1 can be provided with limiting force and resistance during the rotation of the handle rod 1 and the tooth 3, and the position of the handle rod 1 after rotation can be fixed.
[0028] like Figure 2-6 As shown, the rotary locking mechanism is located between the handle rod 1 and the handle seat 2. The rotary locking mechanism includes a cover plate 4 rotatably disposed on the side of the handle seat 2 near the handle rod 1, a rotating ring 41 fixedly disposed in the cover plate 4, and a second arc-shaped hole 42 opened in the rotating ring 41 and communicating with the limiting hole 22. Several second steel balls 43 are rotatably disposed in the second arc-shaped hole 42 for fully entering the limiting hole 22 and the first arc-shaped hole 31 after the cover plate 4 is rotated ninety degrees. The connecting column 11 is located inside the rotating ring 41.
[0029] By rotating the cover plate 4 on one side of the handle seat 2 by 90 degrees while keeping the handle rod 1 and handle seat 2 stationary, the rotating ring 41 and other components can be rotated accordingly. After rotating 90 degrees, the rotating ring 41 can be guided through the arc surface of the second arc hole 42, and the second steel ball 43 inside it is completely pressed into the limiting hole 22 of the handle seat 2 and the first arc hole 31 of the tooth 3. At this time, the rotated second steel ball 43 will disengage from the second arc hole 42 and abut against the inner wall of the rotating ring 41 to lock and fix the cover plate 4, handle seat 2 and handle rod 1, thereby enabling the handle to be rotated and locked to prevent accidental opening.
[0030] Furthermore, when it is necessary to cancel the rotation lock, the cover plate 4 can be rotated 90 degrees in the opposite direction to return to its original position. Then, the handle rod 1 can be rotated to drive the tooth 3 and other components to rotate. After the tooth 3 rotates, it can be guided by the inner arc surface of the first arc hole 31, and push the second steel ball 43 inside it back into the second arc hole 42 and the limiting hole 22, thereby resetting the second steel ball 43.
[0031] like Figure 2 , Figure 5 and Figure 6 As shown, countersunk holes 23 extending toward the cover plate 4 are provided on both sides of the outer wall of the handle seat 2. When it is necessary to rotate the cover plate 4 by 90 degrees, the operator can use his / her fingers to pull the cover plate 4 toward the handle rod 1 from the countersunk hole 23 to create a large gap between the cover plate 4 and the handle seat 2, and then rotate the cover plate 4 by 90 degrees through the gap.
[0032] It should be noted that when the handle with the rotating locking mechanism needs to be rotated and locked, the operator can use his fingers to move the cover plate 4 towards the handle rod 1 from the countersunk hole 23, so that a large gap appears between the cover plate 4 and the handle seat 2. Then, the cover plate 4 is rotated 90 degrees through the gap, while keeping the handle rod 1 and the handle seat 2 stationary. At this time, the cover plate 4 will drive the rotating ring 41 and other components to rotate. After rotating 90 degrees, the rotating ring 41 can be guided through the arc surface of the second arc hole 42, and the second steel ball 43 inside it is completely pressed into the limiting hole 22 of the handle seat 2 and the first arc hole 31 of the tooth 3.
[0033] At this time, the rotated second steel ball 43 will disengage from the second arc-shaped hole 42 and abut against the inner wall of the rotating ring 41, thereby locking the cover plate 4, handle seat 2 and handle rod 1 from the inside, thus locking and fixing the cover plate 4, handle seat 2 and handle rod 1, and thus rotating and locking the handle to prevent accidental opening, making it less likely for children to open the window and cause accidents, and improving the safety performance of the handle.
[0034] Furthermore, when it is necessary to cancel the rotation lock, the cover plate 4 can be rotated 90 degrees in the opposite direction to return to its original position. Then, the handle rod 1 can be rotated to drive the tooth 3 and other components to rotate. After the tooth 3 rotates, it can be guided by the inner arc surface of the first arc hole 31, and push the second steel ball 43 inside it back into the second arc hole 42 and the limiting hole 22, thereby resetting the second steel ball 43.
[0035] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
