Abstract
The utility model discloses an emulsion pump with a spring being arranged outside, and belongs to the technical field of precision parts of emulsion pumps. The emulsion pump comprises a press head, a main column, a nut and a lock cover mounted on the nut, wherein one end of the main column is spliced into the press head; the other end of the main column is spliced into the lock cover; the main column is sleeved with a spring piece, one end of the spring piece pushes against the press head; and the other end of the spring piece pushes against a boss arranged at the bottom end of the inner side of the lock cover. The emulsion pump is simple in structure and convenient to use, and the emulsion pump can be prevented from being corroded and stained by the metal spring piece.
Description
Technical field
The utility model relates to a kind of lotion pump with external spring, belongs to emulsion pumps precision component technical field.
Background technology
Emulsion pumps is very common in daily life, for our life provides great convenience, is widely used in daily use chemicals and pharmaceuticals industry.Present emulsion pumps mainly is made of emulsion pumps body, principal post, pair post, piston, nut, head, pump pearl and spring, pump pearl and spring all are installed in the emulsion pumps body, contact fully with emulsion, because pump pearl and the spring of existing product all adopt the metal manufacturing, long period of soaking is in emulsion, just might go bad, and then pollute emulsion.
Summary of the invention
For addressing the above problem, the utility model provides lotion pump with external spring a kind of simple in structure, easy to use.
The utility model is that the technical scheme that its problem of solution adopts is:
A kind of lotion pump with external spring, comprise head, principal post, nut and be installed in locking closure on the nut, one end of principal post is plugged in the head, its other end is plugged in the locking closure, described principal post is arranged with spring installation outward, described spring installation one end is supported on head, and its other end is supported on the boss that is arranged on the inboard bottom of locking closure.
Preferably, be provided with the protection ring that does not expose for the protection of spring installation on the described head.
Preferably, the outside of described protection ring is arranged with dismantled and assembled anti-pressure folder to prevent that head is pressed.
The beneficial effects of the utility model are: the two ends of spring installation are supported respectively on head and locking closure, when the user presses head, principal post moves down, and spring installation is compressed and produce elastic energy, when the user unclamps head, the elastic energy of spring installation is released, head is up pushed away, simultaneously principal post is taken up, the utility model is simple in structure, easy to use, can prevent that emulsion pumps from being infected by the corrosion of metal spring spare.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structure cutaway view of the present utility model;
Fig. 2 is the enlarged drawing of A section among Fig. 1.
The specific embodiment
A kind of lotion pump with external spring shown in accompanying drawing 1, accompanying drawing 2, comprise head 1, principal post 2, nut 3 and be installed in locking closure 4 on the nut 3, one end of principal post 2 is plugged in the head 1, its other end is plugged in the locking closure 4, the described principal post 2 outer spring installations 5 that are arranged with, described spring installation 5 one ends are supported on head 1, and its other end is supported on the boss 41 that is arranged on locking closure 4 inboard bottoms.
Preferably, be provided with the protection ring 11 that does not expose for the protection of spring installation 5 on the described head 1.Protection ring 11 has enough length, makes head 1 when not being pressed, and the bottom of protection ring 11 is positioned at locking closure 4 inside, and spring installation 5 just can not expose.And the external diameter of protection ring 11 is less than the internal diameter of locking closure 4, and locking closure 4 inside are provided with enough spaces, when the user presses head 1, protection ring 11 can be moved down in locking closure 4, until be arranged on the boss 41 of locking closure 4 inboard bottoms.
Further, the outside of described protection ring 11 is arranged with dismantled and assembled anti-pressure folder 6 to prevent that head 1 is pressed.When milk tank in transportation, or the user just can prevent pressing folder 6 to be enclosed within on the protection ring 11 need not use milk tank the time, head 1 just can't be pressed.
Principle of work of the present utility model is, the two ends of spring installation 5 are supported respectively on head 1 and locking closure 4, and when the user pressed head 1, principal post 2 moved down, spring installation 5 compressed and generation elastics energy, when the user unclamped head 1, the elastic energy of spring installation 5 was released, and head 1 is up pushed away, simultaneously principal post 2 is taken up, the utility model is simple in structure, and is easy to use, can prevent that emulsion pumps from being infected by the corrosion of metal spring spare.
Above specification sheets is described, only is principle of the present utility model and embodiment, everyly carries out any simple modification and variation according to essence of the present utility model, all belongs within the desired protection domain of the utility model.
