Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

Detailed description of the preferred embodiment

Referring to fig. 1, a safety fastener for a pump head, includes a snap ring 11, in this embodiment, the snap ring 11 is oval, and other shapes such as round, rectangular, etc. may also be used, the snap ring 11 itself is hollow, and both ends of the hollow structure extend toward the snap ring 11 to form two symmetrical pressing spaces 12, the two pressing spaces 12 are respectively located at the farthest ends (i.e. the major axis of the oval) of the snap ring 11, a protrusion 13 is disposed outside the snap ring 11, a plurality of pressing blocks are further disposed on the outer wall of the protrusion 13, the pressing blocks can increase the friction force when a finger contacts, the two protrusions 13 are respectively located outside the two pressing spaces 12, so as to facilitate the application of force when the snap ring 11 is pressed, the two protrusions 13 and the snap ring 11 can be integrally formed, and the snap ring 11 is made of a material capable of generating elastic deformation (when the external force is deformed, the original shape can be completely recovered after the external force is removed), whether the lug 13 can not change the function of the lug due to the material, when the lug 13 and the snap ring 11 are integrally formed, the lug 13 is consistent with the snap ring 11 in material, the snap ring 11 can deform along with the deformation of the lug 13, the pressing space 12 is arranged to increase the deformation space of the snap ring 11 and the lug 13, time and labor can be saved when the deformation is caused by pressing, and convenience is brought to the movement of the snap ring 11 after deformation.

Referring to fig. 2, the snap ring 11 is sleeved on the threaded neck 23 between the pump head pressing portion 21 and the pressing cover 22, the diameter of the bottom surface of the pressing portion 21 is a, the length of the snap ring 11 from the nearest two ends (i.e., the minor axis of the ellipse) is b, in a non-use state, b is less than or equal to a, the snap ring 11 can contact with and clamp the bottom surface of the pressing portion 21, and the pump head can be prevented from being pressed when not in use, so that internal liquid leakage is caused; in a use state, the two convex blocks 13 are simultaneously extruded, so that the oval-shaped clamping ring 11 deforms towards the circular direction, at the moment, b is larger than a, the clamping ring 11 can be pushed upwards and then sleeved on the pressing part 21, and the pressing cover 22 can be pressed to enable the internal liquid to flow out; when the outlet of the pump head needs to be closed again, the snap ring 11 is simply moved downward from the pressing portion 21 to the threaded neck 23.

Detailed description of the utility model

The difference between this embodiment and the first embodiment is that the inner portion (i.e., the hollow structure) of the snap ring 11 is provided with a limiting piece, the limiting piece and the snap ring 11 can be integrally formed, and the limiting piece is made of a material capable of generating elastic deformation, i.e., can generate deformation along with the deformation of the snap ring 11;

the two limiting pieces are arc-shaped, the two limiting pieces are oppositely arranged at two ends of the clamping ring 11 which are close to each other, the distance between the two limiting pieces is c, in a non-use state, c is less than or equal to a, the limiting pieces can be in contact with the bottom surface of the pressing part 21 and clamp the pressing part, and the stability is higher compared with that of the specific embodiment; in the using state, the two limiting pieces deform towards the direction tending to the circle, at the moment, c is larger than a, so that the clamping ring 11 can be pushed upwards, and then the two limiting pieces are sleeved on the lower half part of the pressing part 21;

the position and the number of the limiting pieces can be changed in practical use, for example, one or more than two limiting pieces are adopted, and when the number is two or more than two limiting pieces, the positions can be arranged symmetrically or asymmetrically.
