When the two clamps are opened, they will be linked to each other through the linkage structure between them. Setting the linkage structure will increase the processing and assembly requirements of the parts in the bottle clamp, increase the manufacturing cost, and make the overall structure of the bottle clamp complicated.

Compared with the double-open active bottle clamp with two clamps linked, the single-open active bottle clamp with a single clamp action has a simpler structure and is more convenient to manufacture; in addition, when the dynamic clamp and the static clamp clamp clamp the bottle mouth, the radial direction of the rotating shaft where the swing rod is located and the angle between the swing arm can be a mechanical self-locking angle, so that the dynamic clamp can be in a self-locking state. At this time, when the swing rod is not driven, the dynamic clamp cannot be opened due to self-locking, and the self-locking of the dynamic clamp can improve the clamping stability; in addition, the single-open active bottle clamp can realize the arbitrary conversion between the left opening structure and the right opening structure without adding parts, so that the versatility of the bottle clamp can be improved; because the pressure angle is small when the dynamic clamp moves and the tension of the tension spring is controllable, the phenomenon of clamping the bottle mouth can be avoided.

[0020] The present invention is further described in detail below in conjunction with specific embodiments and drawings.

[0021] like Figure 1 , Figure 2As shown, a single-opening active bottle clamp comprises: a bottom plate 1, and a dynamic clamping piece 2 and a static clamping piece 3 are respectively arranged on the left and right sides of the front end of the bottom plate 1. The single-opening active bottle clamp in this embodiment is a left-opening structure. At this time, the dynamic clamping piece 2 is arranged on the left side of the bottom plate 1, and the static clamping piece 3 is arranged on the right side of the bottom plate 1; Fig. 9 As shown, in actual production, the single-open active bottle clamp can also be set as a right-opening structure, in which the dynamic clamping piece 2 is set on the right side of the bottom plate 1, and the static clamping piece 3 is set on the left side of the bottom plate 1; the rear end of the static clamping piece 3 is fixed to the bottom plate 1, and the rear end of the dynamic clamping piece 2 is hinged to the bottom plate 1, so that the dynamic clamping piece 2 can swing left and right, and the dynamic clamping piece 2 can cooperate with the static clamping piece 3 to clamp the bottle mouth after swinging inward, and a swing arm 4 for driving the dynamic clamping piece 2 to swing is also provided on the rear end of the dynamic clamping piece 2, and a rotating shaft 5 is fixed on the bottom plate 1, and the rotating shaft 5 and the static clamping piece 3 are located on the bottom plate 1. On the same side of the swing arm 4 and behind the static clamp 3, a rotating frame 6 is provided between the rotating shaft 5 and the dynamic clamp 2, one side of the rotating frame 6 is passed through by the rotating shaft 5 and is hinged to the rotating shaft 5, so that the rotating frame 6 can swing back and forth around the rotating shaft 5, a coaxial swing rod 8 and a roller 7 are installed on the rotating frame 6, and the roller 7 can rotate on the rotating frame 6, and a curved groove 9 is provided on the rear end of the swing arm 4, and one end of the swing rod 8 is inserted into the curved groove 9. When the rotating frame 6 swings back and forth with the swing rod 8, the swing rod 8 can move along the curved groove 9, and on the rear end of the bottom plate 1 A positioning column 10 is provided, and a tension spring 11 is provided between the positioning column 10 and the rotating frame 6. One end of the tension spring 11 is connected to the positioning column 10, and the other end of the tension spring 11 is connected to the rotating frame 6. Under the action of the tension spring 11, the rotating frame 6 will swing backward with the swing rod 8. At this time, the swing rod 8 can drive the movable clamping piece 2 to swing inward by interacting with the curved groove 9, so that the movable clamping piece 2 and the static clamping piece 3 can clamp together. When the movable clamping piece 2 and the static clamping piece 3 clamp the bottle mouth, the angle α between the radial direction of the rotating shaft 5 where the swing rod 8 is located and the swing arm 4 can be a mechanical self-locking angle. Thereby, the movable clamp can be put into a self-locking state. In the present embodiment, the mechanical self-locking angle is 90 degrees. At this time, when the swing rod 8 is not driven, the movable clamp 2 cannot be opened due to self-locking. The self-locking of the movable clamp 2 can improve the clamping stability. When the roller 7 contacts the cam and rolls along the cam wheel surface, the roller 7 can drive the rotating frame 6 to overcome the tension of the tension spring 11 and swing forward around the rotating shaft 5. After the swing rod 8 swings forward driven by the rotating frame 6, it can interact with the curved groove 9 to drive the movable clamp 2 to swing outward, so that the movable clamp 2 and the static clamp 3 can be opened.

[0022] In this embodiment, the dynamic clamp 2 and the static clamp 3 are located above the base plate 1, the rotating shaft 5, the rotating frame 6, the swing rod 8, the roller 7, the positioning column 10, and the tension spring 11 are located below the base plate 1, and the upper end of the swing rod 8 passes through the avoidance hole 12 on the base plate 1 and is inserted into the curved groove 9.

The top of the mounting column 18 is provided with a screw hole, the middle part of the static clamping nut 16 is an anti-rotation section 19 that can cooperate with the anti-rotation hole, the lower part of the static clamping nut 16 is a stud section 20, and the middle part of the dynamic clamping nut 17 is a cylindrical section 21 and an anti-rotation section that can cooperate with the anti-rotation hole from top to bottom. 19. The lower part of the dynamic clamp nut 17 is a stud section 20, and the cylindrical section 21 cannot pass through the lower anti-rotation hole 13. When installing the static clamp 3, the anti-rotation section 19 on the static clamp nut 16 is inserted into the upper anti-rotation hole 14 on the static clamp 3 and inserted into a lower anti-rotation hole 13 on the base plate 1. At this time, the anti-rotation section on the static clamp nut 16 can cooperate with the lower anti-rotation hole 13 and the upper anti-rotation hole 14 to prevent the static clamp 3 from rotating. The top of a mounting column 18 is threadedly connected to the stud section 20 of the static clamp nut 16. After tightening the mounting column 18, its top can be against the base plate 1 At this time, the static clamping piece 3 can be fixed on the base plate 1 by the static clamping nut 16 and the mounting column 18; when installing the dynamic clamping piece 2, the cylindrical section 21 on the dynamic clamping nut 17 is inserted into the circular hole 15 of the dynamic clamping piece 2, and the anti-rotation section 19 on it is inserted into another lower anti-rotation hole 13 on the base plate 1. At this time, the anti-rotation section 19 on the dynamic clamping nut 17 can cooperate with the lower anti-rotation hole 13 to prevent the dynamic clamping nut 17 from rotating, and the dynamic clamping piece 2 can swing around the cylindrical section 21. In actual production, a flange bearing is also installed between the dynamic clamping piece 2 and the cylindrical section 21. The top of another mounting column 18 is threadedly connected to the stud section 20 of the dynamic clamp nut 17. After tightening the mounting column 18, its top can be abutted against the base plate 1. At this time, the dynamic clamp 2 can be hinged to the base plate 1 through the dynamic clamp nut 17 and the mounting column 18; a first axial hole 22 and a second axial hole 23 are provided on the base plate 1, and the upper end of the rotating shaft 5 can be detachably inserted in the first axial hole 22, and the upper end of the positioning column 10 can be detachably inserted in the second axial hole 23. The rotating shaft 5 and the first axial hole 22, the positioning column 10 and the second axial hole 23 can be connected by threads. After such arrangement, it is convenient to remove the movable clamping piece 2, the static clamping piece 3, the rotating frame 6, the rotating shaft 5, the swing rod 8, and the positioning column 10 from the bottom plate 1, and then the bottom plate 1 is turned 180 degrees, the movable clamping piece 2 and the static clamping piece 3 are installed in interchangeable positions, and other parts are installed according to corresponding hole positions and positions. The single-opening active bottle clamp can be transformed from a left opening structure to a right opening structure without adding parts, thereby realizing the free conversion of the left opening structure and the right opening structure, which can improve the versatility of the bottle clamp; in addition, the bottle clamp can be fixed on the dial by two mounting columns 18. Fixing by two mounting columns 18 can reduce the contact area between the bottle clamp and the dial, thereby reducing the cleaning dead angle and facilitating cleaning.

[0024] The swing rod 8 is detachably mounted on the rotating frame 6 through a latch, and the roller 7 is movably sleeved on the swing rod 8. This arrangement can simplify the structure.

[0025] A rotatable wear-resistant sleeve is mounted on the end of the swing rod 8 inserted into the curved groove 9. The upper and lower sides of the wear-resistant sleeve are respectively limited by the retaining spring. Driven by the swing rod 8, the wear-resistant sleeve can roll in the curved groove 9 and interact with the curved groove 9 to drive the movable clamp 2 to open and close. The wear-resistant sleeve is more wear-resistant and can extend the service life of the bottle clamp.

[0026] During operation, the cam is installed on the frame at the position where the movable clamping piece 2 needs to be opened. As the dial rotates, the single-opening active bottle clamp opens the movable clamping piece 2 through the cooperation of the roller 7 and the cam. When it is necessary to clamp the bottle, the roller 7 is separated from the cam, and the movable clamping piece 2 is reset under the action of the tension spring 11 and cooperates with the static clamping piece 3 to clamp the bottle mouth; since the pressure angle of the movable clamping piece 2 is small when it moves and the tension of the tension spring 11 is controllable, the phenomenon of clamping the bottle mouth can be avoided.
