Cover with safety buckle device

Technical Field

The utility model relates to the technical field of pump head parts, in particular to a cover with a safety buckle device.

Background

The prior cosmetic liquid or washing and protecting article containing device generally uses a bottle body with a pump head, so that the cosmetic liquid or washing and protecting article can be conveniently pumped out. However, when the cosmetic or the washing and protecting article used by carrying the bottle is out, the cosmetic or the washing and protecting article is easily extruded and pumped out by mistake, so that the waste of the cosmetic or the washing and protecting article and the dirt of the case are caused.

In order to avoid the problem, the existing operation is to install a safety buckle on the pump head to prevent the pressing part from descending to pump out cosmetics or washing and protecting articles, but the existing safety buckle needs to be taken down when the cosmetics or washing and protecting articles are used, so that forgetting to clamp the safety buckle back is easy to cause, and even the safety buckle is lost. The other half of the safety buckles which are also used for solving the problem are fixed on the pump head, the other half of the safety buckles can be pulled to enable the pump head to be pressed downwards, but when the pump head is clamped by the half of the fixed safety buckles, the half of the pump head is in contact with the safety buckles, the other half of the pump head is suspended, the pump head can incline to one suspended side when being extruded by the outside, cosmetics or washing and protecting products can be pumped out in a small amount, and even the pump head is damaged.

Disclosure of Invention

To overcome the above-mentioned drawbacks, an object of the present utility model is to provide a cap with a safety catch device that can be fixed to a pump head to prevent loss, and can be in uniform contact with the pump head when the pump head is caught, can prevent a small amount of liquid from being pumped out, and can prevent damage to the pump head.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a take safety buckle device's lid, is applied to the pump head, includes lid and safety buckle device, safety buckle device includes annular snap ring, be provided with fixed part in the axial of snap ring, fixed part fixed connection is on the lid, fixed part is fixed on the lid, prevents that the operator from forgetting to install safety buckle device on the pump head to prevent that safety buckle device from losing after taking down. The snap ring is characterized in that an opening is formed in the position, opposite to the fixing portion, of the snap ring, the opening is formed in the axial direction of the snap ring, the snap ring is divided into two ring pieces by the fixing portion and the opening, and an elastic piece is connected between the fixing portion and the ring pieces, so that the two ring pieces are elastic, the two ring pieces can spring towards the inside or the outside of the snap ring relative to the fixing portion, and the diameter of a cavity formed by the two ring pieces can be increased and reduced. One end of each ring piece far away from the fixing part is connected through a buckling structure, so that the opening is closed. When the pump head needs to be limited to be pressed down, the buckling structure is pulled to enable the buckling structure to close the opening, at the moment, the two annular sheets spring towards the inside of the clamping ring relative to the fixing part, at the moment, the diameter of a cavity surrounded by the two annular sheets is smaller than that of the pump head, so that the pump head can be supported, the pump head cannot be pressed down relative to the safety buckling device, and cosmetics or washing and protecting articles and the like cannot be pumped out; at this moment, the upper end face of the ring piece is in uniform contact with the cover body and has larger contact area, so that the pump head can be supported, and the pump head is prevented from being inclined when being extruded, so that liquid in the bottle is prevented from being pumped out by a small amount, and the pump head can be prevented from being damaged due to the inclination of the pump head under the action of external pressing force.
