As shown in Fig. 1 a and 1b, emulsion pumps 1 comprises pressure head 10, facing 20, cylinder 30 and piston rod 40.The upper end of cylinder 30 is connected with facing 20, and lower end is stretched in container 2(is shown in that Fig. 8 a).The upper end of piston rod 40 is connected with pressure head 10, and lower end is stretched in the space in cylinder 30, and the inner space of piston rod 40 is connected with the outlet of pressure mouth 11 on pressure head 10.Between cylinder 30 and piston rod 40, be provided with spring 50,50 pairs of piston rods 40 of this spring apply power upwards.
Fig. 2 a～2c shows the pressure head 10 of emulsion pumps 1 of the present utility model, and wherein Fig. 2 a is section drawing, and Fig. 2 b is upward view, and Fig. 2 c is block diagram.Fig. 3 a～3d shows the facing 20 of emulsion pumps 1 of the present utility model, and wherein Fig. 3 a is front elevation, and Fig. 3 b is birds-eye view, and Fig. 3 c is block diagram, and Fig. 3 d is face upwarding stereogram.
As shown in Figure 2 a, the pressure mouth 12 that pressure head 10 comprises head sleeve 12 and extends from head sleeve.On head sleeve inside face, be provided with negative thread 13 and at least one perpendicular gear piece 14.This perpendicular gear piece 14 comprises spigot surface 141 and blocking surface 142.Spigot surface 141 starts to extend along the direction of opening of pressure head 10 from the inside face of head sleeve, and with the tangential direction of pressure head 10 at an angle.Blocking surface 142 is arranged in a side contrary with spigot surface 141 of perpendicular gear piece 14.The tangential direction angulation of spigot surface 141 and pressure head 10 is less than the tangential direction angulation of blocking surface 142 and pressure head 10.
Accordingly, as shown in Figure 3 a, on the outside face of facing 20, be provided with outside thread 23 and at least one perpendicular tooth piece 24.This perpendicular tooth piece 24 also comprises spigot surface 241 and blocking surface 242.The spigot surface 241 of perpendicular tooth piece 24 starts to extend along the locking direction of pressure head from the outside face of facing, and angled with the tangential direction of facing 20.The blocking surface 242 of perpendicular tooth piece 24 is arranged in a side contrary with spigot surface 241 of perpendicular tooth piece 24.The tangential direction angulation of spigot surface 241 and facing 20 is less than the tangential direction angulation of blocking surface 242 and blocking surface facing 20.
At this, it should be noted that, because pressure head 10 and facing 20 are roughly installed coaxially, so the tangential direction of the tangential direction of pressure head 10 and facing 20 is also roughly consistent.
In Fig. 2 b, with long and short dash line, show the inscribed circle 16 of the perpendicular gear piece 14 of pressure head 10, in Fig. 3 b, show the circumscribing circle 26 of the perpendicular tooth piece 24 of facing 20.In the utility model, the radius of inscribed circle 16 is less than the radius of circumscribing circle 26.Like this, when pressure head 10 turns to while making position that perpendicular gear piece 14 contacts with perpendicular tooth piece 24 with respect to facing 20, erect between gear piece 14 and perpendicular tooth piece 24 and will produce interference fit.
As shown in Fig. 4 a～4d, by the perpendicular gear piece 14 and the perpendicular tooth piece 24 that arrange according to said structure, when along locking direction rotary press head 10, the spigot surface 141 of the perpendicular gear piece 14 of pressure head 10 and spigot surface 241 move toward one another of the perpendicular tooth piece 24 of facing 20.Now, the interaction between spigot surface 141 and spigot surface 241 will make perpendicular gear piece 14 elastic deformations, thereby make perpendicular gear piece 14 can cross perpendicular tooth piece 24, as shown in Fig. 4 b～4c.And when when opening direction rotation pressure head 10, the perpendicular blocking surface 142 of gear piece and blocking surface 242 move toward one another of perpendicular tooth piece, both interfere with each other, thereby stop that pressure head is further rotated, as shown in Fig. 4 a and 4d.Only have when further applying the more high pulling torque that is enough to destroy perpendicular gear piece 14 to pressure head 10, pressure head 10 just can be further rotated and open.
Therefore, in transportation, if when pressure head 10 is subject to the moment of torsion along locking direction, spigot surface 141 and 241 move toward one another, thus perpendicular gear piece 14 can be crossed perpendicular tooth piece 24, so pressure head 10 can be with respect to facing 20 idle running.And if pressure head 10 in transportation because of collision or fall and be subject to along opening the moment of torsion of direction, between blocking surface 142 and 242, will have the effect mutually stopping, and moment of torsion is now not enough to destroy perpendicular gear piece 14 conventionally, therefore can prevent that pressure head 10 from opening.
As shown in Fig. 2 a and 3a, on the inside face of head sleeve 12, be also provided with smooth surface 15, on the outside face of facing 20, be also provided with smooth surface 25.The height of this smooth surface 15 is made as to h1, and the height of negative thread 13 is made as h2.The height of outside thread 23 is made as to H1, the height of smooth surface 25 is made as to H2.
By structure and the size of negative thread 13, outside thread 23 and smooth surface 15,25 are set, make the pressure head 10 can be with respect to facing 20 idle running when the moment of torsion being subject to along locking direction.Specifically, the height h1 of the smooth surface on pressure head 10 15 is arranged to be more than or equal to the height H 1 of the outside thread 23 on facing 20, the height h2 of the negative thread on pressure head 10 13 is arranged to be less than or equal to the height H 2 of the smooth surface 25 on facing 20.Like this, between pressure head 10 and facing 20, form " jumping tooth " structure.Specifically, when pressing pressure head 10 downwards and with respect to facing 20 during towards locking direction rotary press head 10, the negative thread 13 of pressure head 10 is meshed with the outside thread 23 of facing 20.Along with pressure head 10 continues rotation, negative thread 13 will all enter on the smooth surface 25 of facing 20, and outside thread 23 will all enter into the smooth surface 15 of pressure head 10.Like this, allow pressure head 10 to continue with respect to facing 20 idle running along locking direction.
Preferably, the quantity of the perpendicular gear piece 14 on pressure head 10 is two or more.In this case, can suitably choose the angular transposition between adjacent two perpendicular gear pieces, make when a perpendicular gear piece 14 is when perpendicular tooth piece 24 on facing 20 contacts, at least one in all the other perpendicular gear pieces can not contact with any one in all the other perpendicular tooth pieces.For example, the angular displacement alpha 1(between adjacent two perpendicular gear pieces 14 can be shown in to Fig. 5) and facing 20 on adjacent two perpendicular tooth pieces 24 between angular displacement alpha 2(see Fig. 6 a and 6b) be arranged to unequal, and angle [alpha]
1with angle [alpha]
2integral multiple also unequal.In addition, if the shared angular range of each perpendicular gear piece 14 is made as to β
1(Fig. 4), will be made as β every the perpendicular shared angular range of tooth piece
2(Fig. 5), above-mentioned angle [alpha]
1should be greater than angle beta
2, angle [alpha]
2should be greater than angle beta
1.Further, suppose that the effective contact angle between perpendicular gear piece and perpendicular tooth piece is θ, that is, make to have between perpendicular gear piece and perpendicular tooth piece the angle of at least part of contact, angle [alpha]
1should be in angle [alpha]
2outside the scope of ± θ.
Or at least one in perpendicular gear piece 14 or perpendicular tooth piece 24 distributes with fitfull spacing, this can increase the probability that at least one perpendicular gear piece 14 does not contact with any one perpendicular tooth piece 24 equally.For example, the angular transposition between the adjacent perpendicular gear piece in perpendicular gear piece and one side can be greater than and its opposite side on adjacent perpendicular gear piece between angular transposition, and both differences are at least the twice of the shared angular range of single perpendicular tooth piece, i.e. 2 β 2.
More than the arrangement of perpendicular gear piece 14 and perpendicular tooth piece 24 is also interchangeable,, the description of perpendicular gear piece is applicable to perpendicular tooth piece that is, and the description of perpendicular tooth piece is also applicable to perpendicular gear piece.
By the distribution of perpendicular gear piece 14 and perpendicular tooth piece 24 is so set, can guarantee that at least one perpendicular gear piece 14 is not because being subject to for a long time the compacting yield deformation of perpendicular tooth piece 24, to guarantee the barrier functionality of perpendicular gear piece 14.
The blocking surface 242 of perpendicular tooth piece 24 can along the radially extension of facing 20 (as Fig. 6 a), also can with facing 20 be radially an angle γ (as Fig. 6 b) who is less than 90 °.
Pressure head 10 is locked onto in the process on facing 20, when horizontally rotating pressure head 10, pressure head 10 need to be pressed downwards along axis.Move downward and match with this of pressure head 10, in the upper end of the perpendicular tooth piece 24 of facing 20, on that one end of perpendicular gear piece 14, chamfering or inclined-plane 243 are set, as shown in Figure 3 c.By this chamfering or inclined-plane 243, when the perpendicular gear piece 14 of pressure head and the perpendicular tooth piece 24 of facing contact, perpendicular gear piece can successfully slip over perpendicular tooth piece in chamfering or inclined-plane on perpendicular tooth piece.
In structure described above, perpendicular gear piece is set on pressure head 10, perpendicular tooth piece is set on facing 20.Perpendicular gear piece herein and perpendicular tooth piece can exchange, that is, perpendicular tooth piece is set on pressure head 10, and perpendicular gear piece is set on facing 20, can realize above-mentioned the purpose of this utility model equally.
In above-described structure, perpendicular tooth piece 24 is arranged on facing 20, but it also can be arranged on the cylinder cover of cylinder 30.
Further, as shown in Figure 3 d, in the bottom of the inside face of the facing sleeve pipe 21 of facing 20, be provided with at least one second perpendicular gear piece 27.Answer in contrast ground, on the opening of container 2, be provided with the second perpendicular tooth piece 67, as shown in Fig. 7 a and 7b.Connection structure between the opening of facing 20 and container 2 is presented in Fig. 8 a and 8b, therefrom can see, the set-up mode of the second perpendicular gear piece 27 and the second perpendicular tooth piece 67 and principle of work and above-mentioned perpendicular gear piece 14 and perpendicular tooth piece 24 are basic identical, can prevent that facing 20 is from the opening accidental release of container 2.
Above perpendicular gear piece 14 and the described structure of perpendicular tooth piece 24 are also applicable to the second perpendicular gear piece 27 and the second perpendicular tooth piece 67 with arranging.
Further, facing is moved back to required moment of torsion from vessel port pine and be preferably greater than pressure head is opened to required moment of torsion from facing, prevent thus when rotary press head, occur that pressure head also do not open the situation that facing and vessel port are first unclamped.For this reason, can take at least one in following mode: by the perpendicular gear piece at the connecting portion place between facing and vessel port with perpendicular tooth piece is arranged to the perpendicular gear piece at the connecting portion place between specific head and facing and perpendicular tooth piece wall thickness is thicker, more and/or the magnitude of interference is larger.In addition, also can take alternate manner as known in the art.
In addition,, in order to make sealing effectiveness better, the direction that facing is got loose from vessel port is arranged to the opposite direction of opening from facing with pressure head.For example, if pressure head is opened and needed clickwise pressure head from facing, left-hand revolution facing will make facing get loose from vessel port, otherwise if the direction of opening of pressure head is anticlockwise direction, clickwise facing will make facing get loose from vessel port.
The benefit arranging is like this leak tightness that can further guarantee container.Its principle is, when pressure head 10 rotates along locking direction, it is corresponding to the direction of opening between facing 20 and container 2, but because pressure head 10 can be with respect to facing 20 idle running, therefore not having moment of torsion is delivered to the connecting portion office between facing 20 and the opening of container 2.And if pressure head 10 is when opening direction rotation, it is corresponding to the locking direction between facing 20 and container 2, now, although because the barrier effect between perpendicular gear piece 14 and perpendicular tooth piece 24 transfers torque to the connecting portion office between facing 20 and the opening of container 2, but its effect is further to tighten facing 20 and container 2, therefore can not cause leakage.
Fig. 9 a and 9b show respectively section drawing and the block diagram of cylinder 30.As shown in Fig. 9 a, the lower surface on cylinder flange limit 31 extends ring sealing plug 32 downwards.The overall diameter of this ring sealing plug 32 is slightly larger than the diameter of the opening of container 2.Like this, when the facing linking together 20 and cylinder 30 are installed in vessel port, ring sealing plug 32 is inserted in vessel ports, and with vessel port interference fit, play the effect of airtight container, as shown in Fig. 8 a.In addition, in the bottom in ring sealing plug 32 outsides, inclined-plane or chamfering are set, ring sealing plug 32 are coupled in vessel port being conducive to.
By ring sealing plug 32 is set, can save the pad that plays sealing function, thereby reduce number of components.And, owing to being side seal between sealing plug and vessel port, and thering is certain length, even if therefore have some pines to move back between facing and bottleneck, still can guarantee not occur to leak.
As shown in Figure 10, in the endoporus top of piston rod 40, be provided with feather valve 41.The overall diameter of this feather valve 41 is slightly larger than the diameter on piston rod 40 endoporus tops.Like this, this feather valve 41 is press fitted in the endoporus of piston rod 40.As shown in Figure 11 a, feather valve 41 is cylindric, its lower ending opening, and upper end is 42 closures of thin-walled.From the birds-eye view shown in Figure 11 b, on the thin-walled 42 of feather valve 41 upper ends with " cross " shape joint-cutting 43.Should " cross " shape joint-cutting 43 under normal condition, be closed, while only having difference of pressure when thin-walled 42 both sides very large, should just open by " cross " shape joint-cutting 43, thereby the liquid in container can flow out.
By feather valve 41 is set, at container, when horizontal, because the difference of pressure on thin-walled 42 both sides of feather valve 41 is little, thereby feather valve can not open, thereby can prevent the leakage of liquid in container.
Contriver of the present utility model also imagines from the structure of the pressure mouth 11 of pressure head 10 and solves anti-loose technical matters of the present utility model.
As shown in Figure 12 a and 12b, the pressure mouth on pressure head 10 11 is arranged to telescopic form.In transportation, pressure mouth 11 may compress into the inside of pressure head 10, as shown in Figure 12 a.In use, can directly pressure mouth 11 be pulled out and can be used.Handle 111 can be set in the front portion of pressure mouth 11, and when pressure mouth indentation pressure head 10, handle 111 partly exposes, so that end user pulls out pressure mouth 11.
As shown in Figure 13 a～14b, pressure mouth 11 can be arranged to folding, for example upwards turnover (Figure 13 a, 13b) or downwards turnover (Figure 14 a, 14b).Between pressure mouth 11 and pressure head 10, by hinge 112, be connected.
As shown in Figure 15 a and 15b, can the pressure mouth of pressure head 10 11 be arranged to split type.As shown in Figure 15 a, in transportation, pressure mouth 11 can be separated with pressure head 10.When using, pressure mouth 11 can be inserted to the corresponding aperture arranging on pressure head 10, to use.
The design of above-mentioned scalable, collapsible and split type pressure mouth 11 makes pressure mouth in transportation, can not be subject to the effect of moment of torsion again, therefore can reduce the risk that pressure head 10 and facing 20 get loose.And such setting also can reduce the risk of pressure mouth 11 fractures.
