Abstract
The utility model discloses a limit ring used in a pipeline connector. The limit ring is arranged on a pipe mouth of the pipeline connector, a plurality of symmetrical lock snap feet which radially outwards protrude are formed on the outer side of the front end of the axial direction of the limit ring, one end of the limit ring is connected with a clamping groove which is disposed on the inner wall of the pipeline connector in a clamping mode through the lock snap feet, the other end of the limit ring extends to the outside of a pipe, a plurality of protruded strips are arranged on the limit ring, and the protruded strips are connected with an axial notch which is disposed on the inner wall of the pipeline connector in a clamping mode. By means of the limit ring used in the pipeline connector, locking effects among seal parts in the pipeline connector are reliable and secure, the sealing performance is good, the pressure-bearing capacity of a pipeline on water is high, the connection and changing of a pipe joint can be easily and rapidly performed, even though the limit ring is used for a long time, the loosing of the limit ring to pipes can not occur, the sealing performance can not be reduced, the usage is convenient, and the cost is lowered.
Description
Technical field
The utility model relates to the pipeline connection area, particularly relates to a kind of lock ring that is used in the pipeline connecting head.
Background technique
Pipeline is industrial requisite basic facilities.Assembling pipe joint is its requisite connection means.
Usually be provided with seal arrangement in the pipeline connecting head.Yet the existing lock ring locking effect that is used for the lock sealing device in the pipeline connecting head is bad, and lock ring can be deviate from from the draw-in groove of inner-walls of duct, and sealing effect is poor, and the dismounting maintenance is inconvenient.
The model utility content
The technical problem that the utility model mainly solves provides a kind of good sealing effect, long service life, can reduce component transposings frequency, reduces cost, easy to use be used for the lock ring in the pipeline connecting head.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of lock ring that is used in the pipeline connecting head is provided, is arranged on the pipeline connecting head mouth of pipe, the said lock ring axial forward end outside is formed with the locking button pin of a plurality of radially evaginations of symmetry; Lock ring one end is through the draw-in groove clamping of locking button pin and pipeline connecting head inwall; The other end extends to outside the pipe, and lock ring is provided with some raised lines, the axial notch clamping of said raised line and pipeline connecting head inwall.
In preferred embodiment of the utility model, the end of said locking button pin forms a taper buckle, the draw-in groove clamping of said buckle and mouth of pipe inwall.
In preferred embodiment of the utility model, said buckle end is a cammed surface.
In preferred embodiment of the utility model, the angle of inclination of said cammed surface is 86 degree-89 degree.
In preferred embodiment of the utility model, said locking button pin is eight, evenly is arranged on the lock ring axial forward end outside.
In preferred embodiment of the utility model, said raised line is 2-4, evenly is arranged on the lock ring axial rearward end outside.
The beneficial effect of the utility model is: the lock ring that the utility model is used in the pipeline connecting head is reliable, firm for the locking effect that respectively seals in the pipeline connecting head between the component; Good seal performance; And make pipeline bigger, can carry out the connection and the transposing of pipe joint easily, apace, lock ring can not take place after the use a very long time yet descend with sealability the card of tubing is only loosening for the bearing capacity of water; Easy to use, and reduced cost.
Description of drawings
Fig. 1 is the perspective view that the utility model is used for the lock ring in the pipeline connecting head;
Fig. 2 is that the A-A that is used for the lock ring in the pipeline connecting head shown in Figure 1 is to sectional view;
Fig. 3 is that the utility model is used for the structural representation that the lock ring in the pipeline connecting head is connected with the pipeline connecting head.
The mark of each parts is following in the accompanying drawing: 1, lock ring, 2, locking button pin, 3, raised line, 4, buckle, 5, cammed surface, 6, draw-in groove, 7, axial notch, 8, lock tooth snap ring, 9, the pipeline connecting head.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the utility model is embodiment comprise:
A kind of lock ring that is used in the pipeline connecting head; Be arranged on pipeline connecting head 9 mouths of pipe; The said lock ring 1 axial forward end outside is formed with the locking button pin 2 of a plurality of radially evaginations of symmetry, and said lock ring 1 one ends are through draw-in groove 6 clampings of locking button pin 2 with pipeline connecting head 9 inwalls, and the other end extends to outside the pipe; Lock ring 1 is provided with some raised lines 3, axial notch 7 clampings of said raised line 3 and pipeline connecting head 9 inwalls.
As shown in Figure 3; Said lock ring 1 one ends are through lock tooth snap ring 8 butts in locking button pin 2 and the pipeline connecting head 9, and the other end extends to outside the pipe, and the lock ring 1 axial forward end outside is formed with eight of the symmetry radially locking button pin 2 of evagination; The end of locking button pin 2 forms the taper buckle 4 that an insertion end external diameter reduces gradually; Buckle 4 bottoms and lock tooth snap ring 8 butts, the mouth of pipe inwall of pipeline connecting head 9 are formed with the draw-in groove 6 corresponding with buckle 4, buckle 4 and draw-in groove 6 clampings.Lock ring 1 is provided with 2-4 bar raised line 3, and the mouth of pipe inwall of pipeline connecting head 9 is formed with the axial notch 7 corresponding with raised line 3, raised line 3 and axial notch 7 clampings on the lock ring 1.Said buckle 4 ends are cammed surface 5, and the angle of inclination is the 86-89 degree, and the utility model is preferably 89 degree.
When lock ring 1 pressurized; Because buckle 4 ends are connected on the lock tooth snap ring 8, and buckle 4 ends employing 89 degree cammed surface 5, buckle 4 promptly can outwards squint; Then buckle 4 contacts tighter with draw-in groove 6; Axial notch 7 clampings of the raised line on the lock ring 13 and pipeline connecting head 9 inwalls simultaneously, thus can prevent that the buckle 4 on the lock ring 1 from deviating from draw-in groove 6, make that the sealability in the pipeline connecting head 9 is better.
This lock ring that is used in the pipeline connecting head is reliable, firm for the locking effect that respectively seals in the pipeline connecting head 9 between the component; Good seal performance; And make pipeline bigger for the bearing capacity of water, can carry out the connection and the transposing of pipe joint easily, apace, the card that 1 pair of tubing of lock ring can not take place after the use a very long time yet ends loosening and sealability decline; Easy to use, and reduced cost.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
