[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a passive reversible container clamping device comprises: a base 1 and a reversing seat 2, wherein a reversing shaft 3 is fixedly arranged on both sides of the reversing seat 2, and the reversing seat 2 is movably supported on the base 1 through the reversing shaft 3. In this embodiment, each reversing shaft 3 is movably supported in a flange bearing on the base 1.

[0020] A pair of clamping blocks 4 are arranged on the flip seat 2, each of which includes a clamping block body 41 and a clamping block connecting rod 42. A clamping portion 411 is arranged on the inner side of each clamping block body 41. The clamping portions 411 of the two clamping block bodies 41 are arranged facing each other, and each clamping block connecting rod 42 is hingedly connected to the flip seat 2 through a pin shaft 5. An elastic component is arranged between each clamping block body 41 and the flip seat 2. Under the elastic force of the pair of elastic components, the clamping portions 411 of the pair of clamping block bodies 41 always have a tendency to be in a clamping state of being close to each other and being able to clamp the mouth of the container 6. The flip seat 2 is provided with a driving component for driving the flip seat 2 to drive the flip shaft 3 thereon to rotate on the base 2.

[0021] The elastic components between each clamp body 41 and the flip seat 2 are compression springs 7, each flip shaft 3 protrudes from the side wall of the flip seat 2 in the direction of the clamp body 41 inside, and the compression spring 7 is mounted on the flip shaft 3 protruding from the side wall of the flip seat 2. The two ends of the compression spring 7 are respectively pressed in the side wall of the flip seat 2 and the blocking groove 401 opened on the outer wall of the clamp body 41. In this embodiment, each clamp body 41 is provided with a drainage hole 402 that is connected to the blocking groove 401. The setting position of the drainage hole 402 ensures that when the clamping part 411 clamps the container 6, the drainage hole 402 is located outside the end of the mouth of the container 6. The setting of the drainage hole 402 can prevent the blocking groove 401 from accumulating stains and bacteria, thereby ensuring the cleanliness of the clamping device.

[0022] In this embodiment, a limiting mechanism is provided between each clamp block connecting rod 42 and the flip seat 2, and the structure of each limiting mechanism includes: a limiting slot 421 is provided on the clamp block connecting rod 42, and a limiting shaft 201 is provided on the flip seat 2 corresponding to the position of each limiting slot 421, and both ends of the limiting slot 421 can be blocked by the limiting shaft 201. The setting of the limiting mechanism is used to limit the range of rotation of each clamp block around the pin shaft 5. The limiting mechanism has a simple structure and is easy to clean, without sanitary dead corners, and is not easy to accumulate dirt.

[0023] In this embodiment, the flip seat 2 includes a flip seat body 21, which is a rectangular frame, and a flip seat connecting ear 22 is provided on both sides of the flip seat body 21; each clamp body 41 is located on the inner side of a flip seat connecting ear 22, the flip shaft 3 is fixedly connected to the flip seat connecting ear 22, and the pin 5 and the limit shaft 201 are installed on the flip seat body 21. The flip seat body 21 with a rectangular frame structure is hollowed out with the clamp 4, the pin 5, the limit shaft 21, the flip shaft 3, and the compression spring 7, which is not only reliably installed, but also ensures that stains can be removed as soon as possible during cleaning, without sanitary dead corners, so that dirt will not accumulate, and the cleanliness of the entire clamping device is greatly improved.
