[0039] Preferably, a hook combination guide groove is provided at the front end of the combination buckle part 5 located between the auxiliary support plates 8 of the first shell 1, and the hook combination guide groove and the combination hook part 7 are inserted and limited to cooperate, so that the combination hook part 7 can complete the embedded limit combination with the combination buckle part 5 more accurately.

[0040] Preferably, a semicircular arc limiting bottom plate 10 is provided at the lower ends of the first shell 1 and the second shell 2, and the semicircular arc limiting bottom plate 10 is inserted under the cover body to limit the upward displacement of the anti-opening mechanism so that the anti-opening mechanism will not be pulled upward from the cover body.

[0041] Preferably, a cover body rotation groove 12 is provided at the upper end of the semicircular arc limiting base plate 10, so that the anti-opening mechanism can rotate more freely after the semicircular arc limiting base plate 10 is installed under the cover body.

[0042] Preferably, the combination holes 11 are arranged at the four corners of the combination end surface of the first shell 1, and the combination columns 21 are arranged at the four corners of the combination end surface of the second shell 2.

[0043] Preferably, the outer edge of the combined end of the combined column 21 is provided with a combined chamfer 22, and the diameter of the combined front end surface of the combined column 21 is smaller than the diameter of the cross section of the combined column 21, so that the insertion and installation is faster and more convenient.

[0044] Preferably, shell anti-deformation openings 23 are provided at both ends of the outer wall of the second shell 2 so that the second shell 2 will not be deformed during production and use.

[0045] Preferably, the rear end of the opening component 3 is provided with an arc-shaped reinforcement protrusion 34 to improve the shape stability of the opening component 3 so that the opening component 3 can rebound quickly after being pressed.

[0046] Preferably, a suspension portion is provided on the arc-shaped reinforcement protrusion 34, and a suspension through hole 35 is opened in the middle of the suspension portion. A rope can be installed in the suspension through hole 35, which is convenient for carrying and placing and prevents the opening component 3 from being lost.

[0047] First embodiment:

[0048] When in use, first insert the first shell 1 into the outer side of the container cover from the side, so that the rotation guide grooves of the auxiliary support plate 8 and the shell reinforcement plate 9 contact the outer wall of the container cover, and then assemble and install the second shell 2 from the other side of the container cover, first align the combination column 21 and insert the combination hole 11 to perform initial assembly positioning, and then insert the combination hook part 7 into the combination buckle part 5, the combination sliding inclined surface 72 at the outer end of the combination hook 71 and the combination guide inclined surface 52 at the front end of the combination slot 51 contact and slide with each other, and during the sliding process, the combination guide inclined surface 52 squeezes the combination hook 71 inward until the combination hook 71 passes through the combination guide inclined surface 52 and is clamped into the combination slot 51, completing the combination of the combination hook part 7 and the combination buckle part 5, and the anti-opening structure can be freely rotatably installed on the container cover, and the pressing tube body or other tube body extending from the upper end of the container cover extends from the extension opening 4 without affecting the use.

[0049] Furthermore, during installation, the lower semicircular arc limiting bottom plate 10 of the first shell 1 and the second shell 2 is inserted into the gap between the lower end of the container cover and the container mouth to limit the up and down displacement amplitude of the anti-opening mechanism. The anti-opening mechanism can realize free rotation through the sliding cooperation between the set cover rotation groove 12 and the lower end of the container cover.

[0050] After it is put into use, ordinary guests can only rotate the external anti-opening mechanism when they want to rotate and open the container cover. By utilizing the structure of the rotation guide grooves of the auxiliary support plate 8 and the shell reinforcement plate 9, the anti-opening mechanism will not drive the container cover to rotate when it is rotated, thus avoiding the problem of the container cover being directly opened, reducing the safety hazards of the container during normal use, and allowing guests to use it with more confidence.

[0051] When the service personnel need to open the container cover to replenish the liquid in the container or make other adjustments, they only need to use the opening component 3, hold the fingers on the holding and pressing grooves 32 of the elastic opening pressure plates 31 on both sides, pass the opening protrusion 33 through the opening through hole 6, and make the inner side of the opening protrusion 33 contact the outer side of the combination hook 71, and forcefully clamp the opening component 3 inwards. The opening guide inclined surface 36 on the inner side of the opening protrusion 33 squeezes the combined sliding inclined surface 72, so that the combination hook 71 is bent inwards. After the combination hook 71 is separated from the combination card groove 51, continue to squeeze the combination hook 71 outwards to separate the combination hook part 7 from the combination buckle part 5. After separation, directly take out the first shell 1 and the second shell 2 to complete the unlocking and opening operation of the anti-opening mechanism. Then the service personnel can open the container cover and perform corresponding operations on the container. The unlocking and opening operation is convenient.

[0052] Second embodiment:

[0053] This embodiment is similar to the first embodiment, except that the combination holes 11 in this embodiment are arranged at the four corners of the combination end surface of the first shell 1 , and the corresponding combination columns 21 are arranged at the four corners of the combination end surface of the second shell 2 .

[0054] Furthermore, in this embodiment, a combined chamfer 22 is provided on the outer edge of the combined end of the combined column 21 .

[0055] Through the above structural improvement, the first shell 1 and the second shell 2 can be installed and assembled more accurately, and the combination column 21 can be assembled into the combination hole 11 along the combination chamfer 22 more easily and quickly, and the pre-positioning operation is more convenient.

[0056] Third embodiment:

[0057] This embodiment is similar to the first embodiment and the second embodiment, except that an arc-shaped reinforcement protrusion 34 is provided at the rear end of the opening component 3 in this embodiment, a suspension portion is provided on the arc-shaped reinforcement protrusion 34, and a suspension through hole 35 is provided in the middle of the suspension portion.

[0058] The design of the arc-shaped reinforcement protrusion 34 can further improve the shape stability of the opening component 3, so that the opening component 3 can rebound quickly after being pressed, thereby better protecting the opening component 3, avoiding the opening component 3 from breaking during use, and extending the service life of the opening component 3.

[0059] Furthermore, by providing a suspension structure on the arc-shaped reinforcement protrusion 34, the user can install a rope in the suspension through hole 35, which makes carrying and storage more convenient and more importantly, can prevent the opening component 3 from being lost.

[0060] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
