Description

A kind of Pressing pump with only pressure ring

Technical field

The present invention relates to daily washing utensil, the Pressing pump of fluid product packing box upper end liquid outlet is specifically mounted to, Particularly a kind of simple structure, the convenient a kind of Pressing pump with only pressure ring of press juice and self-locking by mistake can be prevented.

Background technology

It is well known that the product packing box such as bathing lotion, shampoo upper end has Pressing pump, as long as being pressed down on just when using It can conveniently go out liquid, but usually when not in use or be placed in luggage people in travelling way and be not intended to it and go out liquid, be that this people has thought one A little methods such as clamp drain pipe with an additional clip, have thus had more an accessory, it is clear that this does not do simply The method of method, and a kind of Pressing pump with only pressure ring can solve this problem easily.

The content of the invention

In order to solve the above problems and meet the market requirement, a kind of Pressing pump with only pressure ring is provided with only pressure ring Cause to go out liquid by mistake to prevent liqiud outlet head from pushing, simple structure, it is easy to operate and self-locking is effective.

Scheme of the present invention is：

A kind of Pressing pump with only pressure ring it is main by cylinder body, cup cylinder cap, drain pipe, only pressure ring, cannelure, go out Liquid head, waling, piston, spring and check valve are constituted, and the drain pipe is conductively cut with scissors through described only pressure ring, its lower end Be connected to above piston, liqiud outlet head described in the grafting of upper end, the piston is connected with spring and check valve and is respectively positioned in turn below In the cylinder body, the cup cylinder cap is in interference fit with the cylinder body upper end, only pressure ring and the cup cylinder cap coaxial one Body is simultaneously located at inner ring, and the upper edge hole of the only pressure ring, which includes two sections and every section, a low bead and high bead, the low bead and There is roundlet pit, described two sections only have two cannelures between pressure ring between the high bead, it is described go out liquid The inserted terminal of head and the drain pipe is barrel-shaped in two rings, and the drain pipe, which is plugged between inner ring, described two ring buckets, to be had Two walings, two walings can be slided up and down in two cannelures.Described in during assembling It is crimped on the bottleneck of packing box upper end, therefore the cylinder body, only cup cylinder cap, pressure on cup cylinder cap by screw cap along face Ring is solidified as a whole with packing box, and the liqiud outlet head can rotate within the specific limits, and the liqiud outlet head is press head.

The beneficial effects of the invention are as follows：

A kind of Pressing pump simple structure cost with only pressure ring is low, easily realizes, easy to operate and self-locking is effective, Discharging liquid by extruding by mistake can be prevented.

Brief description of the drawings

Further illustrated with reference to the figure of the present invention：

Fig. 1 is the cylinder body, only cup cylinder cap, pressure ring, drain pipe position relationship schematic diagram；

Fig. 2 is Fig. 1 top view；

Fig. 3 is the liqiud outlet head outside drawing；

Fig. 4 is Fig. 3 upward view；

Fig. 5 is outside drawing of the present invention.

In figure, 1. cylinder bodies, 2. cup cylinder caps, 3. drain pipes, 4. only pressure ring, 5. cannelures, 6. liqiud outlet heads, 7. is longitudinally reinforced Muscle.

Embodiment

If Fig. 1 is the cylinder body, only cup cylinder cap, pressure ring, drain pipe position relationship schematic diagram, the mistake of cup cylinder cap 2 It is full of and is matched with the upper end of cylinder body 1, the only pressure ring 4 is with the coaxial one of the cup cylinder cap 2 and positioned at inner ring, the drain pipe 3 are conductively articulated with above piston through the only pressure ring 4, its lower end, liqiud outlet head 6 described in the grafting of upper end, under the piston Face is connected with spring and check valve in turn and is respectively positioned in the cylinder body 1, and the upper edge hole of the only pressure ring 4 includes two sections and every section There are low bead and high bead, there is a roundlet pit between the low bead and the high bead.

If Fig. 2 is Fig. 1 top view, described two sections only have between pressure ring and reflect described in two cannelures 5, figure The upper port of cannelure 5.

If Fig. 3 is the liqiud outlet head outside drawing, such as Fig. 4 is Fig. 3 upward view, the liqiud outlet head 6 and the drain pipe 3 Inserted terminal is barrel-shaped in two rings, and the drain pipe 3 is plugged in described longitudinally reinforced with two between inner ring, described two ring buckets Muscle 7, two walings 7 can be slided up and down in two cannelures 5, and the waling 7 is reflected in Fig. 4 End face.

If Fig. 5 is outside drawing of the present invention.

A kind of Pressing pump with only pressure ring is main by cylinder body 1, cup cylinder cap 2, only drain pipe 3, pressure ring 4, longitudinal direction Groove 5, liqiud outlet head 6, waling 7, piston, spring and check valve are constituted, and the drain pipe 3 is through the only pressure ring 4, under it End is conductively articulated with above piston, liqiud outlet head 6 described in the grafting of upper end, and the piston is connected with spring and unidirectional in turn below Valve is simultaneously respectively positioned in the cylinder body 1, the cup cylinder cap 2 in interference fit with the upper end of cylinder body 1, the only pressure ring 4 with it is described The coaxial one of cup cylinder cap 2 is simultaneously located at inner ring, and the upper edge hole of the only pressure ring 4, which includes two sections and every section, low bead and high edge Mouthful, there is roundlet pit, described two sections only have described in two between pressure ring between the low bead and the high bead Cannelure 5, the inserted terminal of the liqiud outlet head 6 and the drain pipe 3 is barrel-shaped in two rings, and the drain pipe 3 is plugged in inner ring, institute Stating between two rings bucket has two walings 7, and two walings 7 can be in two cannelures 5 Inside slide up and down, the length of slip is piston stroke.

In use, the cup cylinder cap 2 on the bottleneck of packing box upper end is crimped on by screw cap along face, it is lower to press institute Liqiud outlet head 3 is stated, the waling 7 is along the slide downward of cannelure 5, and the drain pipe 3 promotes piston downwards, under piston The cylinder space in face, which reduces, causes liquid to force the fluid into the drain pipe 3 by the check valve on piston area；In institute when letting go State spring effect lower piston upwards, cause the cylinder space below piston expands to produce negative pressure, and pass through the lower spring end Liquid in the check valve suction packing box, so repeatedly.Can be as needed in the suction pipe of cylinder body lower end grafting certain length.

When the liqiud outlet head 6 is rotated into an angle relative to the only pressure ring 4, the at this moment end of the waling 7 Face along it is described only pressure ring 4 the low bead slide into fall into the roundlet pit untill, cause the liqiud outlet head 6 under by And self-locking is, it is necessary to slightly firmly reversely rotate the liqiud outlet head 6, the end face of the waling 7 is departed from roundlet when using Pit simultaneously returns to the top of cannelure 5 along the low bead, at this moment because the side of another section of high bead has propped up institute Waling 7 is stated, prevents the liqiud outlet head 6 from being rotated further, you can press down again, accurate positioning.The liqiud outlet head 6 rotates The drain pipe 3 is driven to have rotation during one angle, but piston does not rotate, because the drain pipe 3 is articulated with piston, because This rotates dynamics very little needed for the liqiud outlet head 6.
