Abstract
The utility model discloses a clamping tooth pressing ring used in a pipeline joint. The clamping tooth pressing ring comprises an annular clamping tooth pressing ring body, wherein a plurality of clamping teeth are uniformly arranged in the circumferential direction on the inner side of the clamping tooth pressing ring body and are inclined downwards to form a conical surface. By the clamping tooth pressing ring used in the pipeline joint, bulges on the clamping tooth pressing ring in the prior art are canceled, so that a pipe can be guided into the pipeline joint so as to optionally rotate, the clamping tooth pressing ring is not clamped with the pipeline joint and can simultaneously rotate along with the pipe, an inner wall of the pipe joint is not scratched, water leakage of the pipeline joint is avoided because the pipeline joint is pulled, and a sealing effect is good; and moreover, after being pressed, the clamping tooth pressing ring can be detached and assembled and has long service life, and the cost is reduced.
Description
Technical field
The utility model relates to the pipeline connection area, particularly relates to a kind of latch pressure ring that is used in the pipeline connecting head.
Background technique
Pipeline is industrial requisite basic facilities.The pipeline connecting head is its requisite connection means.
Usually be provided with seal arrangement in the pipeline connecting head, yet the latch pressure ring of existing pipeline connecting head inner sealing device is provided with some protruding 6 (as shown in Figure 4), the groove clamping of this convexity and pipeline connecting head inwall usually in the outer ring; Fix the latch pressure ring; If but pipeline inner conduit rotation then can drive the latch pressure ring and rotate simultaneously, thus the scratch tube wall, and the latch pressure ring also can damage simultaneously; Then can cause pipeline connecting head sealing effect to reduce, reduce working life.
The model utility content
The technical problem that the utility model mainly solves provides the latch pressure ring in the pipeline connecting head that is used for of a kind of simple in structure, good sealing effect, long service life.
For solving the problems of the technologies described above; The technological scheme that the utility model adopts is: a kind of latch pressure ring that is used in the pipeline connecting head is provided; Comprise annular snap tooth pressure ring body, said latch pressure ring body inner circumferential evenly is provided with some latches, the downward-sloping formation conical surface of said latch.
In preferred embodiment of the utility model, said latch pressure ring is arranged between the seal joint and lock tooth snap ring in the pipeline connecting head, and the latch pressure ring is connected with seal joint and lock tooth snap ring respectively through latch.
In preferred embodiment of the utility model, said latch and the interior corresponding setting in plane of inclination of seal joint, the flanged lip on the said lock tooth snap ring is connected on the latch.
In preferred embodiment of the utility model, said latch is trapezoidal, and the angle of inclination of latch is 60 degree-70 degree, and the latch end is provided with the arc tooth.
In preferred embodiment of the utility model, said latch pressure ring is stainless steel gear ring.
In preferred embodiment of the utility model, said latch is the elasticity latch.
The beneficial effect of the utility model is: the utility model is used for the latch pressure ring in the pipeline connecting head owing to cancelled the convexity on the existing technology latch pressure ring, can let pipe import to realize in the pipeline connecting head rotation arbitrarily, the latch pressure ring not with the clamping of pipeline connecting head; Can rotate simultaneously with pipe, can scratch pipeline connecting head inwall, prevent that the pipeline connecting head from leaking because of pulling; Good sealing effect; And can dismantle and assemble behind the pressurized, longer service life has reduced cost.
Description of drawings
Fig. 1 is the perspective view that the utility model is used for latch pressure ring one preferred embodiment in the pipeline connecting head;
Fig. 2 is the front elevation of Fig. 1;
Fig. 3 is the structural representation that the utility model latch pressure ring is connected with the pipeline connecting head;
Fig. 4 is the structural representation of the interior latch pressure ring of pipeline connecting head in the existing technology;
The mark of each parts is following in the accompanying drawing: 1, latch pressure ring body, 2, latch, 3, seal joint, 4, lock tooth snap ring, 5, the pipeline connecting head, 6, convexity.
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 latch pressure ring that is used in the pipeline connecting head 5 comprises annular snap tooth pressure ring body 1, and said latch pressure ring body 1 inner circumferential evenly is provided with some latches 2, the said latch 2 downward-sloping formation conical surfaces.
Wherein, said latch pressure ring is stainless steel gear ring, and said latch 2 is the elasticity latch, and easy to make, cost is lower.
As shown in Figure 3; Said latch pressure ring is arranged between the seal joint 3 and lock tooth snap ring 4 in the pipeline connecting head 5; The latch pressure ring is connected with seal joint 3 and lock tooth snap ring 4 respectively through latch 2, the corresponding setting in plane of inclination that said latch 2 and seal joint 3 are interior, and the flanged lip on the said lock tooth snap ring 4 is connected on the latch; It is reliable, firm that this structure connects, and sealability is better.
This is used for the latch pressure rings in the pipeline connecting head 5 owing to cancelled the convexity 6 on the existing technology latch pressure ring, can let pipe import to realize in the pipeline connecting head rotation arbitrarily, the latch pressure ring since not with the clamping of pipeline connecting head; Can rotate simultaneously with pipe, can scratch pipeline connecting head 5 inwalls, prevent that pipeline connecting head 5 from leaking because of pulling; Good sealing effect; And can dismantle and assemble behind the pressurized, longer service life has 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.
