Abstract
The utility model belongs to the technical field of pump body connection equips and specifically relates to a rapid seal connects pump connection structure of hard tube. The utility model aims to solve the technical problem that a rapid seal connects pump connection structure of hard tube that can let the quick and sealing connection of the pump body and hard tube is provided. Rapid seal connects pump connection structure of hard tube imports and exports end and hard tube including the pump body of taking the threaded connection end, and still include and hug closely the sealing washer that cup joints in one section outer fringe surface of hard tube, the hard tube has still cup jointed the nut lid outward, the sealing washer sets up between threaded connection end and hard tube, the nut lid is connected hard tube and pump body exit end through the screw -thread fit between holding with threaded connection. The utility model relates to a retrench, it is minimum to the change of existing equipment, have wide marketing prospect, the utility model discloses needing to be particularly useful for the occasion of the pump body and hard tube high -speed joint.
Description
Technical field
This utility model relates to the pump housing and connects equipment field, and a kind of fast sealing connects the pump attachment structure of hard tube.
Background technology
The capital equipment that pump shifts as liquid, is widely used in daily life.But the pump housing of pump mostly uses plastics at present
Structure, therefore, during connecting line, imports and exports two ends and is tightly connected to be able to realization, mostly use hose connection mode.When even
When connecing hard tube, structure is the most relative complex.Nesting metal tube when being molded generally by the pump housing, then with Quick Connect Kit by pump
Metal tube be connected with main body pipeline, but this structure is owing to being to mould structure covered with gold leaf, can produce stress cracking when ambient temperature is too low.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can allow the pump housing and hard tube quickly and be tightly connected the closeest
Envelope connects the pump attachment structure of hard tube.
This utility model solves the technical scheme is that fast sealing of its technical problem and connects the pump attachment structure of hard tube, bag
Include pump housing entrance end and the hard tube of threaded connection end, also include the sealing ring being close to be socketed on one section of outer fringe surface of hard tube,
Also being socketed with nut cap outside described hard tube, described sealing ring is arranged between threaded ends and hard tube, described nut cap by with
Threaded engagement between threaded ends and hard tube and pump housing entrance end are connected.
Further, including being arranged at the sealing ring collar stop of sealing ring termination, described sealing ring collar stop and nut cap
It is close to.
Further, including being arranged at the annular groove of hard tube outer fringe surface, described annular groove is arranged at hard tube outer fringe surface
And between sealing ring.
Further, the shape of cross section of described nut cap is polygon.
The beneficial effects of the utility model are: when actually used, only need to first be close to sealing ring be socketed on one section of outer rim of hard tube
Surface, then receives in pump housing entrance end by sealing ring set, finally, by the nut cap being socketed on outside hard tube and threaded ends
Between threaded engagement and hard tube and pump housing entrance end are connected.In like manner, during dismounting also it is very convenient.This reality
Simplifying by new design, the change to existing equipment is minimum, has wide marketing prospect, and this utility model is especially suitable
In the occasion needing the pump housing to be quickly connected with hard tube.
Accompanying drawing explanation
Fig. 1 is the explosive view of this utility model structure.
Fig. 2 is the schematic diagram after this utility model structure connects.
Figure is labeled as: pump housing entrance end 1, threaded ends 11, sealing ring 2, sealing ring collar stop 21, nut cap
3, hard tube 4, annular groove 41.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
Fast sealing as shown in Figure 1 and Figure 2 connects the pump attachment structure of hard tube, and the pump housing including threaded connection end 11 passes in and out
Mouth end 1 and hard tube 4, also include the sealing ring 2 being close to be socketed on 4 one sections of outer fringe surfaces of hard tube, and described hard tube 4 is outer to be also socketed
Having nut cap 3, described sealing ring 2 to be arranged between threaded ends 11 and hard tube 4, described nut cap 3 is by with screw thread even
Connect the threaded engagement between end 11 and hard tube 4 and pump housing entrance end 1 are connected.
When actually used, owing to sealing ring 2 is arranged between threaded ends 11 and hard tube 4, therefore can well ensure
Sealing.Next, due to the threaded engagement between nut cap 3 to be ensured and threaded ends 11, hard tube 4 and the pump housing are entered
The port of export 1 connects, and therefore, needs to ensure that nut cap 3 needs to obtain the support force that sealing ring 2 provides when screwing, and this
The counteracting force of support force is then as the driving force connecting hard tube 4 and pump housing entrance end 1.General, for the ease of installing and
Dismounting, the shape of cross section of described nut cap 3 is preferably polygon.
In order to further improve the steadiness being connected between sealing ring 2 with nut cap 3, such scheme can be selected: include
Being arranged at the sealing ring collar stop 21 of sealing ring 2 termination, described sealing ring collar stop 21 is close to nut cap 3.Such as Fig. 1
Shown, nut cap 3, as a raised structures, preferably can be played the effect of clamping by sealing ring collar stop 21, from
And ensure sealing property and nut cap 3 stability when connecting.
In order to further improve sealing, such scheme can be selected: include that the annular being arranged at hard tube 4 outer fringe surface is recessed
Groove 41, described annular groove 41 is arranged between hard tube 4 outer fringe surface and sealing ring 2.As shown in Figure 1, the ring set up
Connected in star 41 can allow sealing ring 2 overstock in annular groove 41 when screwing, thus further improves sealing.
This utility model design is simplified, and the change to existing equipment is minimum, has wide marketing prospect.
