Abstract

The utility model relates to a pipe joint, which comprises a pipe sleeve, a gasket and two eccentric handles, wherein, two pairs of lugs are arranged on the pipe sleeve, and the two eccentric handles are respectively positioned between each pair of lugs of the pipe sleeve. The utility model is characterized in that the position on the outer side of a rotary shaft hole on each lug corresponding to the outer margin of the eccentric minor axis of the handle is added with a plug pin hole, two bolts are inserted into the two corresponding holes for tightly pinning the handle. The utility model has the advantages of simple structure, easy fabrication, convenient use and good pinning effect. In addition, the handle which is locked tightly has the strong stress bearing ability.

Description

Pipe joint

The utility model relates to a kind of pipe joint, relates in particular to a kind of oil pipe and liquid medium pipe joint of being used for.

Existing liquid medium pipe joint, its pipe joint (outer tube) and the mode that compresses of being taken between (interior pipe) are to realize (see figure 1) by handle eccentrically weighted shaft structure set on the pipe joint, when managing in its eccentric major axis packing after handle 4 rotations, make the inner and outer pipe combination; During disengaging, mat handle base draw ring 5 pull-up handles 4 make the eccentric minor axis of handle towards interior pipe, and inner and outer pipes can separate.This pipe joint does not have locking device because of its handle, therefore when the handle ring is pullled by his thing collision, in case the eccentric major diameter of handle leaves when managing the position in the packing, liquid state in the pipe is just excessive, for example large car such as common trailer finishes when departing when refueling, and easily brushes up against the draw ring of pipe joint on the transport pipe and produces the excessive problem of above-mentioned handgrip displacement oil.For this reason, someone once designed a kind of have prevent the openhanded liquid medium pipe joint that takes off, its structure mainly adds a lug at the lug tail end, and penetrates grip hole and lug hole simultaneously when reaching handle and managing with latch in eccentric major diameter packing, no longer can be shifted because of brushing up against.Though this structure can realize the purpose that handle is anti-loose, but need add a lug, and need aim at simultaneously when using on the handle and two lugs on three holes, so more time-consuming, use inconvenience, need the holes of boring in the middle of the handle shank more in addition, this reduces the ability that meets with stresses of handle, so still undesirable.

The purpose of this utility model is to design liquid medium pipe joint that a kind of new having prevent that handle from getting loose, and it can overcome the shortcoming of prior art, make its installation, easy to use, the ability that meets with stresses is stronger, and is and simple in structure, make easily.

The purpose of this utility model is achieved in that this pipe joint, by pipe box, packing ring, be arranged at two pairs of lugs on the pipe box, place the rotating shaft between every pair of lug and two eccentric handgrips being arranged in two rotating shafts are formed, it is characterized in that eccentric minor axis outer rim corresponding section respectively adds a hinge last under the rotating shaft position outside and handgrip packing state on two pairs of lugs, two latches can insert in respectively in two pairs of hinge lasts.

In the said structure, when managing in the eccentric major axis packing of handgrip, that is eccentric minor axis is when outer, insert the effect that just can play the locking handgrip in two pairs of holes that newly add with latch, (referring to Fig. 6) then pulls out these two latches earlier in the time will unclamping, rotate handgrip then, make its eccentric minor axis near in it, inner and outer pipe just unclamps.The pipe joint of this structure compared with the prior art, and is simple in structure, makes easily, and cost is low, and mortise lock only needs second eyelet during locking, and this makes things convenient for manyly than wearing three eyelets, and speed is also faster, in addition, it does not need on handgrip to make a call to a hole more yet again, so that meeting with stresses of handgrip is strong.

Further illustrated with drawings and Examples below.

Description of drawings:

Fig. 1 is existing liquid medium pipe joint front view.

Fig. 2 is Fig. 1 sectional view.

Fig. 3 is the existing liquid medium pipe joint front view that has the handgrip locking device.

Fig. 4 is Fig. 3 sectional view.

Fig. 5 is the structural representation of the utility model liquid medium pipe joint.

The schematic representation that Fig. 6 is in the lock state for the eccentric handgrip of pipe joint among Fig. 5.

As seen from Figure 5, liquid medium pipe joint of the present utility model, by pipe box 1, packing ring 3, be arranged at two pairs of lugs 2 on the pipe box 1, place the rotating shaft 6 of lug 2 and place the eccentric handgrip 4 in the rotating shaft 6 to be formed, eccentric handgrip 4 ends are provided with draw ring 5, it is characterized in that eccentric minor axis outer rim corresponding section respectively adds 22, two latches 8 of a hinge last under two pairs of lugs, 2 upper spindle holes, 21 outsides and handgrip 4 packing states can insert in respectively in two pairs of hinge lasts 22 (referring to Fig. 6).

Claims

1, a kind of pipe joint, by pipe box, packing ring, be arranged at two pairs of lugs on the pipe box, place the rotating shaft between every pair of lug and two eccentric handgrips being arranged in two rotating shafts are formed, it is characterized in that eccentric minor axis outer rim corresponding section respectively adds a hinge last under the rotating shaft position outside and handgrip packing state on two pairs of lugs, two latches can insert in respectively in two pairs of hinge lasts.
