In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A connection structure between a bottle lock cap and a bottle body, which includes a bottle mouth and a bottle lock cap that seals the bottle mouth, and is characterized in that a circle of inwardly protruding flanges is provided at the lower part of the inner wall of the bottle lock cap, and The upper part is provided with a circle of protruding ribs, and the flange of the bottle lock cap is fastened to the lower edge of the ribs. On the top of the bottle lock cap, there is a ring-shaped sealing ring matching the bottle mouth. The outer wall of the ring is close to the inner wall of the bottle mouth, and an anti-rotation structure is arranged on the outer wall of the bottle mouth and the inner wall of the lock bottle cap to prevent the lock bottle cap from rotating.

The connection structure between the bottle lock cap and the bottle body as described above is characterized in that the anti-rotation structure includes ribs on the inner wall of the bottle lock cap and grooves on the outer wall of the bottle mouth, and the ribs are located on the flange Above, grooves are provided on the ribs, and the ribs are placed in the grooves.

The connection structure between the bottle lock cap and the bottle body as described above is characterized in that the anti-rotation structure includes a groove on the inner wall of the bottle lock cap and ribs on the outer wall of the bottle mouth, and the groove is set On the flange, the ribs are located under the convex ribs, and the ribs are placed in the grooves.

The connection structure between the bottle lock cap and the bottle body as described above is characterized in that the anti-rotation structure includes ribs arranged on the inner wall of the bottle lock cap and a plurality of ribs evenly distributed on the outer wall of the bottle mouth. The strips get stuck between adjacent ribs.

The connection structure between the bottle lock cap and the bottle body as described above is characterized in that the number of ribs is 12.

Compared with the prior art, the utility model has the following advantages: the combination of the lock bottle cap and the bottle mouth of the utility model is a bayonet type, and the positioning and fastening are performed by the engagement of the flange and the rib, and the traditional screw connection method is abandoned , improving production efficiency. The sealing ring is sealed with the bottle mouth, no gasket is needed, material is saved, energy saving and environmental protection are achieved. In addition, it has the characteristics of simple structure and easier assembly.

【Detailed ways】

The utility model is described in detail below in conjunction with accompanying drawing:

A connection structure between a bottle lock cap and a bottle body, comprising a bottle mouth 1 and a bottle lock cap 2 that seals the bottle mouth 1, and a pump body that can pump out the liquid in the bottle body 7 is connected to the bottle lock cap 2 8.

As shown in FIG. 1 , a ring of inwardly protruding flanges 3 is provided at the lower part of the inner wall of the bottle lock cap 2 . On the upper part of the outer wall of the bottle mouth 1, a circle of outwardly protruding ribs 4 is arranged. When the bottle lock cap 2 is pressed toward the bottle mouth 1, the flange 3 of the bottle lock cap 2 will be fastened on the lower edge of the rib 4, so that the bottle lock cap 2 is fastened on the bottle body 7. An annular sealing ring 5 matching the bottle mouth 1 is arranged on the top of the bottle lock cap 2 . When the flange 3 of the locking bottle cap 2 is fastened on the rib 4 lower edge, the outer wall of the sealing ring 5 will be close to the inner wall of the bottle mouth 1 to seal it.

An anti-rotation structure 6 for preventing the rotation of the locking bottle cap 2 is provided on the outer wall of the bottle mouth 1 and the inner wall of the locking bottle cap 2 . The anti-rotation structure 6 can be realized in many ways.

As shown in FIG. 2 , way one, the anti-rotation structure 6 includes a rib provided on the inner wall of the locking bottle cap 2 and a groove 62 provided on the outer wall of the bottle mouth 1 . The ribs are located on the flange 3 , and the grooves 62 are arranged on the raised ribs 4 . Described rib is placed in the groove 62, then lock bottle cap 2 can not rotate.

As shown in FIG. 3 , mode 2, the anti-rotation structure 6 includes a groove provided on the inner wall of the locking bottle cap 2 and a rib 64 provided on the outer wall of the bottle mouth 1 . The groove is provided on the flange 3 , and the rib 64 is located under the convex rib 4 . Described rib 64 places in the groove, then lock bottle cap 2 can not rotate.

As shown in FIG. 4 , mode 3, the anti-rotation structure 6 includes a rib provided on the inner wall of the locking bottle cap 2 and a plurality of ribs 66 evenly distributed on the outer wall of the bottle mouth 1 . In this embodiment, the number of ribs 66 is 12. The ribs are stuck between the adjacent ribs 66, so the lock bottle cap 2 cannot rotate.
