Technical Field

[0001] The utility model relates to the field of pump body functional parts, in particular to a hinge-type limit clip for a push pump. Background Art

[0002] The push pump limiter is used to limit the pumping action of the push pump. It can prevent accidental pump operation during transportation or carrying outside. It is commonly found in push pump bottles, such as shower gel, shampoo, facial cleanser, etc. Push pump limiters are generally packaged as disposable limiters before leaving the factory, which means that they need to be destructively dismantled to release the limiter for use, or they are separated limiters, which require cumbersome operations to remove the limiter before unlocking and use. The removed limiter is extremely easy to lose and cannot be used a second time. Utility Model Content

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer, the following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solution of the utility model through the implementation method. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Example 1

[0035] One of the implementation methods of the present application of a press pump hinged limit clamp is as follows: Figures 1 to 6 , applied to a pressing pump bottle 1, the pressing pump bottle 1 is provided with a pressing head 2, including: an annular seat 3, at least one elastic bridge 4 and at least one limiting hinge 5. In this embodiment, the limiting hinge 5 is provided with two pieces.

[0036] In a preferred embodiment, the bottom end of the limit hinge 5 is elastically connected to the annular seat 3 via an elastic bridge 4, so that the limit hinge 5 swings around the elastic bridge 4 as an axis and switches between an open state and a closed state.

[0037] A limiting platform 521 is provided on the limiting hinge 5; a limiting protrusion 5211 is provided on the upper surface of the limiting platform 521 for engaging and connecting with the lower edge 21 of the pressing head in the closed state.

[0038] When in use, the limiting protrusion 5211 switches positions between the inner side and the outer side of the lower edge of the pressing head 2 as the limiting hinge 5 rotates and opens and closes, and the inner side of the lower edge of the pressing head is on the pumping path of the pressing head 2. When the limiting protrusion 5211 is on the inner side of the lower edge of the pressing head 2, that is, when the limiting protrusion 5211 is on the pumping path of the pressing head 2, the limiting protrusion 5211 will limit the pumping action of the pressing head 2.

[0039] Specifically, a support 522 is provided below the limiting platform 521. The support 522 is vertically abutted against the lower surface of the limiting platform 521. The support 522 is used to enhance the stability and reliability of the limiting platform 521. The height of the limiting protrusion 5211 is adaptively selected according to the elastic deformation degree of the material.

[0040] More specifically, the limiting hinge 5 is entirely or partially made of elastic material, which provides a stress deformation basis for switching the limiting state.

[0041] More specifically, the elastic bridge 4 is made of elastic material to provide a stress deformation basis for switching the limit state.

[0042] More specifically, the elastic bridge 4 is in the shape of an arc bridge; the bridge head and the bridge tail are respectively connected to the bottom end of the limit hinge 5 and the annular seat 3; the bridge body 41 of the elastic bridge 4 is arched toward the center.

[0043] More specifically, the upper edge of the limiting protrusion 5211 is inclined to facilitate guiding and opening and closing with less effort.

[0044] More specifically, the upper end of the limit hinge 5 is an arc-shaped inclined surface 51, which is arranged outside the annular seat 3. The arc-shaped inclined surface 51 can facilitate the user to apply force and feel comfortable when pressing the limit hinge 5, and on the other hand, because the arc-shaped inclined surface 51 is arranged at the upper end of the limit hinge 5 and outside the annular seat 3, the center of gravity of the limit hinge 5 will be biased to the outside, and when the limit hinge 5 is opened, it is ensured to fall outward naturally in a natural state to prevent mis-limitation.

[0045] More specifically, the limiting protrusion 5211 in the position switching is higher than the lower edge of the pressing head 2 .

[0046] The working principle of the utility model is:

[0047] When installing the push pump bottle 1, the annular seat 3 is sleeved and fixed on the bottle mouth of the push pump bottle 1, and the limit hinge 5 is closed, so that the limit hinge 5 is engaged and connected with the lower edge 21 of the push head through the limit platform 521. Under the action of the limit platform 521, the push head 2 cannot move downward, and the limit locking is realized, which can prevent the push head 2 from squeezing out the liquid in the push pump bottle 1 or the foam foamed by the liquid due to external force interference when not in use.

[0048] When the push pump bottle 1 needs to be used, the limit hinge 5 connected to the lower edge 21 of the push head is opened, and the two limit hinges 5 are unfolded to the outside. After the expansion, the limit platform 521 on the limit hinge 5 is located on the outside of the lower edge 21 of the push head. At this time, the push head 2 is pressed, and the push head 2 can move up and down to squeeze out the liquid in the push pump bottle 1 or squeeze out the foam foamed from the liquid. After use, if the push pump bottle 1 needs to be limited and locked again, it is only necessary to apply external force inward on the outside of the limit hinge 5, such as pinching with two fingers, so that the limit platform 521 is again engaged with the lower edge 21 of the push head.

[0049] In addition, the upper end of the limit hinge 5 is an arc-shaped inclined surface 51, which can better fit the fingertips, conform to ergonomic design, and save effort to prevent slipping when pinching.

[0050] The pressing pump limiter designed in the utility model is not only simple in structure, but also has an ergonomically designed limit hinge 5 with an arc-shaped inclined surface 51, which is convenient and labor-saving to operate. The pressing pump does not need to be disassembled for use and will not be lost.
