[42] described box body 6 comprises a support accessory 30 in this example, and the lower limb of this support member is formed above-mentioned middle lower limb, and described conduit 22 nestles its extension.This support member is seen better on Fig. 3, and wherein, the part of a wall of described box body is taken away.Described support accessory 30 can be in described main body 20 slides along described Vertical direction, and by resetting means for example spring 32 be reset to described bottom towards described conduit.Described resetting means is default to be used for the power of regulating reposition force and applying, and described device comprises a for example control button 34, and it is placed in the top edge of described main body 20.Therefore, the described spring 32 of can regulate is applied to described supravasal power, and described conduit self nestles against described pulley.
[43] naturally, only described described pump head at this, known described pump self comprises other member, the drive unit of for example described rotation system 14, and control gear or the like, these are traditional types.
[44] described pump head 4 is included in the support device of the box body in the described cache 12.Described device comprises two spars 40,42, and described spar is parallel to described axle 18 ground and extends to another wall 8,10 ground from a described wall 8,10.This between centers places between described two spars.Described two spars extend in the plane identical with described axle 18.
[45] especially as seen, one of two support arms 24 of described box body 6 have a hook shaped ends 44, and this end has a protruding pin, and this protruding pin extends on described support arm outer surface as Fig. 3 to Fig. 5.To the position of each described box body 6, described spar 42 comprises a hole 46, and extend on the inner surface of described spar in this hole.Described hole 46 is designed for and receives described hook shaped ends 44, to stop described corresponding support arm moving towards the top.The main body 20 of described box body 6 is bearing on the rib of this spar by a convex shoulder 48 of this same support arm in addition.
[46] for described box body is installed, described box body 6 is vertically put into described cache 12 down on described pump head 4, note its inclination so that described hook end 44 can enter in the described hole 46 between the same time.In case this joint is finished, the described box body 6 that just tilts is so that another support arm 24 is near corresponding described spar 40.By part that described box body 6 lockings are in place then, described part is described below.
[47] for the position of each box body, described spar 40 comprises that a followup device 50 and a design are used for the locked groove 52 that cooperates with described followup device 50.
[48] described followup device 50 illustrates with front view on Fig. 7 to Figure 13 especially.It consists essentially of a cylindrical body that elongates, but intermediate portion 51 is shapes of the parallelepiped at right angle, is vertical between four outer surfaces of this intermediate portion, and is parallel to the main shaft of described followup device 50.Described followup device 50 has an outer end 54, and this outer end extends to outside the described spar 40.Described followup device has an inner end 56 in addition, and this inner end extends in described spar 40.This inner end is half spheroid form, and the equatorial plane of described spheroid constitutes the internal surface of described head, and with described body be adjacent.Therefore, the outer surface of described head is a semi-spherical shape.
[49] for each followup device 50, the elongation shape seat groove 60 that described spar 40 comprises.Design this groove 60 so that described followup device 50 radial direction along described followup device 50 in described seat groove 60 is free to slide.But, described spar 42 comprises the obstruction part 63 of a plane shape, this obstruction part has the fork-shaped opening on top on one day, in this fork-shaped opening, imbedded the part of described body between described part 51 and head 56, to form a block of described head, forbid that described followup device 50 escape to outside the described seat groove 60 fully.
[50] described seat groove 60 also is formed so that described followup device 50 in described seat groove around one 64 free turn, described axle is especially shown in Figure 11 and 13, and described axle 64 vertically extends.Therefore, this is especially perpendicular to the glide direction of described followup device 50.This extends in the plane of the part 61 of described fork-shaped opening, and is determined by described fork-shaped opening.Guiding in the process that the described followup device of intermediate portion 51 assurances of described followup device 50 moves in its groove 60.
[51] described spar 40 comprises the reset components that the compartment of terrain is arranged in addition, this reset components is elastic board chip 66 forms on a plane, and it extends facing to described head, and stimulates the spherical circumferential surface of described head, leave its groove to promote described followup device 50, promptly towards described box body.In this example, described plate 66 can freely rotate around a lower shaft 62, and this lower shaft is perpendicular to the radial direction of described axle 64 and described followup device 50, and perpendicular to the plan of doing of accompanying drawing 12.In this example, described obstruction part 63 and described plate 66 cutting formings, and steel plate rolls (pliage d ' unet le).Therefore they form a single part.
[52] especially with reference to Fig. 5 and Fig. 6, described locked groove 52 extends on an outer surface of the support arm 24 of described box body, and it is relative with described followup device 50 that described locked groove is designed.This outer surface is an indent, so that, relative and by described locked groove surface and described followup device 50 perpendicular to described followup device---on the front view of Fig. 6 especially as seen, make described locked groove 52 be designed to the outer end 54 that guides and stimulate described followup device 50, there is the bus that is basically parallel to described followup device radial direction on described locked groove surface.
[53] with reference to Fig. 6, described locked groove comprises a zone 70, and these 70 whiles of zone are as the inlet region and the outlet area of described followup device 50.Described zone with shown in the inner 72 of support arm 24 adjacent.
[54] on described regional intermediate portion, extending has a convex portion 74, protrudes from described regional 70 towards described followup device.
[55] above the right of the above convex portion 74 of Fig. 6 and described regional 70, described locked groove 52 comprises that one enters pipe 76, and this enters pipe 76 and extends along described Vertical direction.
[56] described enter pipe after, described locked groove 52 has left an arrival bend 78, this bend is particularly including a supporting surface 80, described supporting surface 80 is towards described bottom and be cylindrical sector.
[57] in described locked groove 52, then this bend is a locking or maintenance district 82, and it extends on described convex portion 74, and particularly including a supporting surface 84, this supporting surface is that cylinder is fan-shaped, and towards described top.
[58] after described regional 84, described locked groove comprise shown in Fig. 6 front view one day a left side come off the curve 86, its shape with described arrival bend 78 is the same.Described coming off the curve self also is associated with a supporting surface 88, and this supporting surface is that cylinder is fan-shaped, and towards described bottom.
[59] described surperficial 80 and 88 radian is centered close to the below on these surfaces, and is relative with described surperficial 84 radian center, and described surperficial 84 radian is centered close on its surface.
[60] come off the curve along described, be extended with one and leave pipe 90, the formation of this pipe is described come off the curve and described outlet area 70 between linking.
[61] described convex portion 74 has a lower support surface 92, this surface on Fig. 6 towards described bottom and the right.At idle position, extend above described followup device 50 on this plane, and when this surface contacts with described followup device, described plane will guide described followup device to the described direction that enters pipe 76.
[62] increase ground, the described pipe 76 that enters has a basal surface, and this basal surface extends with plane form facing to described followup device 50, and slightly towards described bottom.Like this, when described followup device passes through this basal surface, be pushed into its groove towards described plate 66.Described inclination especially on Fig. 8 as seen.
[63] basal surface of described arrival bend 78 be the plane with vertical.The ingress edge of this basal surface 78 has difference on the degree of depth with respect to the described edge that leaves that enters pipe 76 basal surfaces, enters described inlet duct 76 to forbid described followup device 50 from described arrival bend 78.Similar mode, the difference of a degree of depth of existence between described maintenance district and described arrival bend 78 so that described followup device 50 can enter into described maintenance district from described arrival bend, can not oppositely move along described passage.At last, between the bottom surface in described maintenance district 82 and described 86 the bottom surface of coming off the curve, there is a similar difference,, can not oppositely moves along described passage so that described followup device 50 can enter described coming off the curve from described maintenance district.These three difference especially on Fig. 8 as seen.
Be pointed out that [64] the described barrel surface 80 and 88 towards the bottom that enters bend and come off the curve passes through the butt joint of one of their edge, to constitute a rib ridge.This rib ridge cooperates with depth difference between described arrival bend 78 and the described maintenance district 82, guides described followup device 86 to leave described maintenance district towards described coming off the curve.
[65] therefore, the basal surface of described arrival bend 78, described maintenance district 82 basal surfaces and described 86 the basal surface of coming off the curve are arranged by the degree of depth, so that end 54 cascades of described followup device 50 move, can arrive described bend 86 then from described bend 78 " decline " to described maintenance district 82.The described pipe 76 that enters allows to be positioned at the directly stroke place of arrival " height " that be made of described arrival bend 78 of described regional 70 described followup device.
[66] with reference to Fig. 7 to 11, therefore, for described locking and release, the operation of described mechanism is continuous.
[67] when described box body is positioned at the position of Fig. 4, in order to carry out locking, the user stimulates described cartridge body, and is for example surperficial from it, vertically applies a pressure 90 towards described bottom.This action is in order that make the surface 92 of described convex portion 74 contact with described followup device 50.Then, initially below this surface 92, there is the described followup device 50 that spacing ground extends to be drawn towards the described direction that enters pipe 76.
[68] Fig. 7 shows at the described followup device that leaves described regional 70 described 76 o'clock described support and the box body of pipe that enter of passing through.Therefore can find that described followup device is actuated and abutted against this plate towards the direction of described plate 66 by the described pipe 76 that enters.Then, in order to follow the described pipe 76 that enters, described followup device 50 slightly changes towards Thuban.
[69] along with the user is applied to pressure on the described box body, described followup device leaves and describedly enters pipe 76, and arrives described arrival bend 78, as shown in Figure 2.Described surperficial 80 form a block of described followup device, and it indicates end towards described box body bottom process for the user.
[70] intuitively, the user alleviates the pressure 90 that is applied on the described box body.Known this pressure and 22 opposite effects of pipeline that are bearing on the described pulley, the elasticity of described pipeline is shifted to top with described support arm 24.Consider the structure of described locked groove, this is accommodated in the described reserved area 82 described followup device 50, and described followup device is bearing on described surperficial 84.Because this supporting, described box body is limited up in its stroke.Described box body is positioned at the operation locked position.
[71] for the described box body of release, the user carries out identical action, described action effect difference at this moment.Be to add a new pressure 90 on the top of described box body equally, this pressure is used to make described servo-actuated rotary device 50 to enter from described reserved area 82 describedly to come off the curve 86.Described followup device is bearing on described surperficial 88, and the user is meaned that described box body finishes towards the stroke on top, and the user weakens its pressure intuitively.
[72] elasticity of described pipeline rises described box body again, and this causes that described followup device moves towards described outer pipe 90, then moves towards described district 70.
[73] thus the user can turn described box body release so that described support arm 24 is therefore free away from relevant spar 42, separate described hook end 44 from described spar 42 then, in order to remove described box body from described support.
[74] can observe, in the process that described followup device 50 moves in described district 78,82 and 86, described followup device 50 slides into outside its groove gradually, so that from the configuration of leaving basically shown in Figure 13 of being configured to of the indentation basically shown in Figure 12.Equally, in the same movement process, described followup device rotates around described axle 64.In the time of in described followup device is received within described reserved area 82, described followup device is positioned at the right, promptly is parallel to described pipeline.When described followup device arrives described bend 86, described followup device towards anticlockwise until leaving described outer pipe 90.When arriving described district 70, described followup device is again in a location right.
[75] therefore, the present invention allows the user by a simple pressure that is applied on the described box body top described box body to be locked on the described support.Then, the user can be with the identical described box body of action release.Therefore, these actions can be carried out quickly and easily, and, if necessary, simultaneously a plurality of box bodys of described pump are carried out one by one.The carrying out that is to be noted that these operations do not need the user to contact with any of described pipeline.But because the flexible intervention of described pipeline, these lockings are conciliate the action of locking and have been determined limited stroke, and described stroke prevents the described pipeline of excessive excitation, especially to the operation when described box body is in running position on described pump head.Especially, described pipeline does not have the danger that suffers an excessive excitation in operating process.This life-span to described pipeline is even more important, and when suffering excessive excitation, its life-span shortens widely by the highly excited pipeline of the operation of described pump.
[76] certain, can design numerous modifications that does not exceed the scope of the invention.
[77] especially can revise the structure of described locked groove and described followup device.Can design described followup device and on described box body, extend, and described locked groove extends on described support.
