Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Refer to fig. 1 to 4. Multi-angle location rocking arm, including rocking arm 1, rotate piece 2, positioning cam 3, connecting rod 4, head rod 5 and second connecting rod 6, head rod 5 runs through rocking arm 1 back, the cover is established in rotating piece 2, second connecting rod 6 runs through connecting rod 4 back, the cover is established in positioning cam 3, be equipped with the pawl 21 on the rotation piece 2, be equipped with on the positioning cam 3 with pawl 21 matched with latch 31, positioning groove 32 has been seted up to positioning cam 3 one side, install setting element 7 on the connecting rod 4, positioning groove 32 corresponds the setting with setting element 7, when positioning cam 3 rotates promptly, positioning groove 32 rotates when setting element 7 department, setting element 7 card is in positioning groove 32 department, can prevent positioning cam 3 further rotation, realize the locate function. Therefore, when the multi-angle positioning rotating arm is used, the door leaf can be positioned at the maximum opening angle, the closing angle of the door leaf and the matched positions of the positioning groove 32 and the positioning piece 7, the use requirements are met, the opening and closing times of the door leaf are reduced, and the service life of the whole body is prolonged.
The utility model discloses a multi-angle location rocking arm is when using, and rocking arm 1 is connected with the organism of external door closer, and connecting rod 4 is installed on the door leaf. When the rotating arm 1 rotates, the rotating member 2 is driven to rotate by the first connecting rod 5. Since the rotating teeth 21 of the rotating member 2 are engaged with the latch teeth 31 of the positioning cam 3, when the rotating member 2 rotates, the rotating teeth 21 act on the latch teeth 31 and drive the positioning cam 3 to rotate. Along with the rotation of the positioning cam 3, when the positioning groove 32 rotates to the position of the positioning part 7, the positioning part 7 is clamped in the positioning groove 32, the positioning effect on the positioning cam 3 is realized, the positioning cam 3 is effectively prevented from further rotating, and then the positioning of the rotating part 2 and the rotating arm 1 is realized through the interaction of the clamping tooth 31 and the rotating tooth 21.
The multi-angle positioning rotating arm further comprises a supporting arm 8, a through hole 81 is formed in one end of the supporting arm 8, the rotating part 2 is sleeved in the through hole 81, and the supporting arm 8 is fixed with the connecting rod 4.
The lower end surface of the connecting rod 4 is provided with a mounting part 41, the supporting arm 8 is fixed with the bottom end of the mounting part 41 through welding or screws, and the positioning piece 7 is positioned on one side of the mounting part 41. The mounting portion 41 and the link 4 are integrally formed.
The positioning member 7 includes a compression spring 71 and a ball 72, a mounting hole 411 is formed in one side of the mounting portion 41, one end of the compression spring 71 is fixed in the mounting hole 411, the other end of the compression spring abuts against the ball 72, and the positioning groove 32 of the positioning cam 3 is arranged corresponding to the ball 72. Wherein, both ends of the compression spring 71 are respectively hooked on the inner wall of the mounting hole 411 and the ball 72. Through the resilience of the compression spring 71, when the positioning groove 32 of the positioning cam 3 rotates to the positioning part 7, the compression spring 71 pushes the ball 72 to be clamped in the positioning groove 32, so that the door leaf position is positioned. When the door leaf needs to be opened or closed further, external force acts on the door leaf, and finally the positioning cam 3 continues to rotate, so that the ball 72 is pressed into the mounting hole 411 by the positioning cam 3, and the positioning effect of the ball 72 is relieved.
The first connecting rod 5 is provided with external threads, the rotating part 2 is provided with internal threads, and the first connecting rod 5 is matched with the rotating part 2 through threads. Therefore, the first connecting rod 5 is convenient to be matched with the rotating part 2, when the first connecting rod 5 rotates along with the rotating arm 1, the first connecting rod 5 drives the rotating part 2 to rotate together, and force and motion are convenient to transmit.
