[0037] like Figures 1 to 7As shown, this embodiment provides a clamping device for clamping bottles, comprising a mounting base 1, a clamp 2, a first fastener 3, a fixing plate 4, and a second fastener 5. The mounting base 1 is provided with two symmetrical assembly areas 11, each of which is provided with a first assembly hole 111. The clamp 2 is located on the upper surface of the mounting base 1, and the fixing plate 4 is located below the mounting base 1. The first fastener 3 passes through the first assembly holes 111 on the clamp 2 and the mounting base 1 in sequence and is then threadedly connected to the fixing plate 4. Thus, the clamp 2 and the mounting base 1 are initially connected via the fixing plate 4 and the first fastener 3. Two clamps 2 are provided, and the two clamps 2 are assembled correspondingly to the two assembly areas 11. Since the two assembly areas 11 are symmetrically arranged, the two clamps 2 are arranged opposite each other. The second fastener 5 is used to secure the fixing plate 4 to the mounting base 1. The first fastener 3 is threadedly connected to the fixing plate 4 to initially secure the clamp 2 to the mounting base 1. Simultaneously, the second fastener 5 secures the fixing plate 4 to the mounting base 1. This ensures a more secure connection between the first fastener 3 and the fixing plate 4, reducing the risk of the clamp 2 moving up and down after prolonged operation. By slightly turning the first fastener 3, the tightening force between the clamp 2 and the mounting base 1 can be adjusted without affecting the stability of the assembly, ensuring smooth opening and closing of the clamp 2 during operation and better gripping of the bottle.

[0038] In this embodiment, the mounting base 1 is provided with a protruding rod, wherein the protruding rod is used to mount to an external workpiece. The external workpiece can be a bracket or a lifting component, without specific limitation. The operating principle and specific mechanism of the lifting component can be referred to in the prior art and will not be elaborated here.

[0039] Regarding the threaded connection between the first fastener 3 and the fixing plate 4, for example, Figure 1 、 Figure 2 and Figure 8 As shown in , the first fastener 3 includes a through-area 31 and a threaded area 32, and the fixing plate 4 is provided with a first fixing hole 41 corresponding to the first assembly hole 111 on the mounting base 1, and the first fixing hole 41 has an internal thread, wherein the through-area 31 in the first fastener 3 is placed in the first assembly hole 111 on the clamp 2 and the mounting base 1, and the threaded area 32 and the internal thread of the first fixing hole 41 are screwed together. Furthermore, part of the threaded area 32 is exposed on the fixing plate 4, and the clamping device also includes a locking nut 6, which is screwed together with the threaded area 32. The provision of the locking nut 6 can further lock the first fastener 3 and the fixing plate 4, reduce the risk of the threaded area 32 on the first fastener 3 and the first fixing hole 41 on the fixing plate 4 loosening during the operation of the clamp 2, and further improve the stability of the assembly of the clamp 2 and the mounting base 1.

[0040] In this embodiment, the fixing plate 4 further includes a second fixing hole 42, and a second assembly hole 112 is provided on the mounting base 1 opposite to the second fixing hole 42, wherein the second fastener 5 passes through the second fixing hole 42 and is threadedly connected to the second assembly hole 112. For example, the second fastener 5 can be a bolt. The clamp 2 in the clamping device in this embodiment is located below the filling valve of the filling equipment and is used to clamp the bottle to be filled with liquid. Therefore, after the staff assembles the clamp 2, the fixing plate 4, the first fastener 3 and the second fastener 5 to the mounting base 1, the staff can first adjust the clamp 2 so that the clamp 2 is aligned with the filling valve, and then tighten the second fastener 5 and the first fastener 3 to firmly assemble the clamp 2 to the mounting base 1. Then, slightly reversely twist the first fastener 3 to adjust the tightening force of the clamp 2 and the mounting base 1 so that the clamp 2 can be opened and closed smoothly. Of course, the second fastener 5 can also be made of glue to stick the fixing plate 4 to the bottom surface of the mounting base 1. Before sticking, the positions of the fixing plate 4 and the clamp 2 are determined so that the clamp 2 and the filling valve are aligned. There is no specific limitation on the selection of the second fastener 5.

[0041] In this embodiment, Figure 1 、 Figure 4 、 Figure 5 and Figure 9 As shown in , the clamping device also includes an elastic member 7 and a limiting plate 8, wherein the limiting plate 8 is positioned at the center of the two clamps 2, and the elastic member 7 connects the two clamps 2. By using the elastic member 7 to connect the two clamps 2, the two clamps 2 can be quickly reset after moving away from each other. After assembly, the two clamps 2 are aligned with the two opposite sides of the limiting plate 8. The provision of the limiting plate 8 ensures the opening between the two clamps 2, preventing the two clamps 2 from getting too close to each other under the action of the elastic member 7, which would affect the clamping of the bottle. Preferably, a protrusion 21 is provided on the clamp 2, and a connecting portion 71 is provided at each end of the elastic member 7. During assembly, the connecting portion 71 is connected to the protrusion 21. Specifically, the protrusion 21 is a protruding column provided on the upper surface of the clamp 2, and the connecting portion 71 is a hook or a fixing ring. During assembly, the hook or fixing ring is placed on the protruding column. In this embodiment, the elastic member 7 can be a spring.

[0042] Preferably, a avoidance groove 12 is provided on the mounting seat 1. Specifically, the avoidance groove 12 is provided between the two assembly areas 11, wherein the limit plate 8 is placed in the avoidance groove 12 and fixed to the fixed plate 4. The provision of the avoidance groove 12 can make the layout of the overall structure of the clamping device more reasonable. The height of the limit plate 8 is greater than the height of the avoidance groove 12, so that the clamp 2 can fit with the side of the limit plate 8. Specifically, the clamping device also includes a third fastener 9, wherein a third fixing hole 43 is provided on the fixed plate 4, the third fastener 9 is used to fix the fixed plate 4 and the limit plate 8, and the third fastener 9 is threadedly connected to the third fixing hole 43. An external thread is provided on the third fastener 9, and an internal thread is provided on the third fixing hole 43 of the fixed plate 4. The external thread of the third fastener 9 and the internal thread of the third fixing hole 43 are screwed together. In this embodiment, the third fastener 9 can be a bolt.

[0043] Preferably, a positioning hole 22 corresponding to the first assembly hole 111 on the mounting seat 1 is provided on the clamp 2, wherein a spacer is provided in the positioning hole 22. The provision of the spacer can further reduce the risk of loosening of the first fastener 3, making the assembly between the clamp 2 and the mounting seat 1 more stable, and improving the stability of the overall structure of the clamping device.

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
