Detailed description of the invention
Below in conjunction with accompanying drawing to this
inventionbe further described.
As shown in Figure 1,
a kind of emulsion pumps that inside and outside locking closure is set, comprise head 1, thread 2, locking closure, body 3, principal post 4, subpost 5, piston 6, spring 7, upper glass bead 81 and lower-glass ball 82, described in
inlet 31 bottom body 3there is lower-glass ball seat at place, and there is upper glass ball seat the upper end of principal post 4; Lower-glass ball 82 and lower-glass ball seat form lower check valve, and upper glass bead 81 and upper glass ball seat form upper check valve; The mozzle 1B described head 1 having liquid outlet 1A and be communicated with liquid outlet, mozzle 1B has outside thread; The upper end of principal post 4 to be inserted in mozzle 1B and is fixed together; The lower end grafting of subpost 5 upper end and principal post 4, piston 6 is arranged on subpost 5; The lower end of spring 7 coordinates with the base plate of the inner chamber of body 3, upper end is connected with the spring perch 51 of the lower end of subpost 5.
Upper inner chamber 32 bearing fit of piston 6 and body 3, lower inner cavity 32 bearing fit of spring perch 51 and body 3.
Described locking closure is divided into inner lock cover 10 and outer locking closure 11,
As shown in Figure 3, described outer locking closure 11 comprises lid 111, is positioned at the mouth piece 112 at lid center and the inserting groove 113 around mouth piece, the inwall of mouth piece 112 has annular protrusion 1121, the inside face of the outer shroud wallboard of inserting groove 113 has annular slot 1131; The top surface of lid 111 there is the stop block 114 at diameter line two ends;
