DETAILED DESCRIPTION
[0017] In the description of the utility model, it needs to be explained that the orientation or position relation that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate is based on the orientation or position relation shown in the drawing, and is only for the convenience of describing the utility model and simplifying the description, and is not to indicate or imply that the indicated device or element must have a particular orientation, to be constructed and operated in a particular orientation, therefore can not be understood as the limitation to the utility model.
[0018] In the description of the utility model, it needs to be explained that unless another explicit provision and limitation, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixed connection, also can be detachable connection, or integrally connected, for the ordinary skill in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0019] The following will be combined with the embodiment and the drawing Figs. 1-4 The technical scheme of the utility model is further described.
[0020] Example 1
[0021] A rotating lifting buckle mechanism, comprising a buckle base 1, a positioning block 2, a sealing bottom cover 3, a rotating handle 4 and a spring 5 arranged between the positioning block 2 and the sealing bottom cover 3, a sliding groove 11 is arranged through the side end of the buckle base 1, the positioning block 2 is slidingly arranged in the sliding groove 11, the sealing bottom cover 3 is fixedly arranged at the bottom end of the buckle base 1 and a through hole 31 is arranged through the middle part of the sealing bottom cover 3, the rotating handle 4 is rotatably arranged in the positioning block 2 through the through hole 31, the lower end of the sealing bottom cover 3 is provided with an inverted U-shaped clamping groove 32, and the middle part of the rotating handle 4 is provided with a limiting pin 41, and the inverted U-shaped clamping groove 32 and the limiting pin 41 are correspondingly arranged.
[0022] As shown in the drawings, in the clamping process, the positioning block 2 moves upward under the elastic force of the spring 5, at this time, the limiting pin 41 on the rotating handle 4 is located in the inverted U-shaped clamping groove 32 at the upper end of the sealing bottom cover 3, and due to the obstruction of the limiting pin 41, the positioning block 2 cannot further rise, and the clamping end thereof is in contact with the workpiece and realizes positioning clamping. Figs. 1-4
[0023] When it is necessary to release the clamping, the operator pulls down the rotating handle 4, so that the limiting pin 41 is separated from the inverted U-shaped clamping groove 32, then the operator rotates the rotating handle 4, so that the limiting pin 41 is not collinear with the projection of the inverted U-shaped clamping groove 32 on the horizontal plane, after the rotating handle 4 is loosened, the rotating handle 4 moves upward due to the elastic force of the spring 5, at this time, since the limiting pin 41 is not collinear with the projection of the inverted U-shaped clamping groove 32 on the horizontal plane, the limiting pin 41 on the rotating handle 4 abuts against the lower end of the sealing bottom cover 3, so that the positioning end on the positioning block 2 is located in the sliding groove 11, thereby avoiding that the positioning end of the positioning block 2 protrudes from the buckle base 1, so that the workpiece can freely move.
[0024] The buckle mechanism can be quickly switched between the locked and unlocked states, and the stability of the workpiece in the clamping state and the mobility of the workpiece in the unlocked state are ensured, the elastic force of the spring 5 can be adjusted to adapt to workpieces of different weights and sizes, so that the buckle mechanism is more flexible and reliable.
