Abstract
The utility model discloses an improved sealing structure of a press oil pipe. The press oil pipe comprises a vertically-extending stand pipe body and a transversely-extending transverse pipe body. The lower end of the stand pipe body is connected with the right end of the transverse pipe body, a first connecting flange is arranged at the upper end of the stand pipe body, a second connecting flange is arranged at the left end of the transverse pipe body, the second connecting flange transversely extends to form a sealing connecting part, the periphery of the middle of the sealing connecting part is provided with a fixing groove, a combination sealing piece is arranged in the fixing groove and comprises an O-type sealing ring and a copper sealing ring, and the O-type sealing ring is attached to the copper sealing ring. In this way, the improved sealing structure of the press oil pipe is simple in structure, the double-layer sealing structure of the O-type sealing ring and the copper sealing ring is adopted, the sealing effect is good, leakage is avoided, and the sealing structure is fixed through the groove without falling.
Description
Technical field
The utility model relates to a kind of improved seal structure of press oil pipe.
Background technique
When press carries out oil pressure, need oil pipe to transmit hydraulic oil, and oil pipe connects, be sealed to as important, there is following defect in existing oil pipe connecting means:
1, conventionally adopt O-ring seal to seal, sealing effect is not good, easily produces and reveals;
2, O-ring seal is easily dislocated, and causes the leakage of a large amount of hydraulic oil, causes occurring engineering accident.
For this reason, artificer of the present utility model is because above-mentioned defect, by concentrating on studies and designing, is comprehensively engaged in for a long time experience and the achievement of related industry for many years, and research and design goes out a kind of improved seal structure of press oil pipe, to overcome above-mentioned defect.
Model utility content
The improved seal structure that a kind of press oil pipe is provided during the purpose of this utility model, it is simple in structure, and good sealing effect has been avoided leakage, and position stability, can not come off.
For achieving the above object, the utility model discloses a kind of improved seal structure of press oil pipe, the transverse tube that wherein oil pipe comprises vertically extending standpipe and horizontal expansion, is characterized in that:
The lower end of described standpipe is connected with the right-hand member of transverse tube, and the upper end of described standpipe is provided with the first flange connector, and the left end of described transverse tube is provided with the second flange connector;
Described the second flange connector laterally extends the portion that is tightly connected, described in the be tightly connected middle part periphery of portion be provided with fixed groove, in described fixed groove, be provided with combination seal;
Described combination seal comprises O RunddichtringO and the copper seal ring mutually reclining.
Wherein: described the first flange connector is circular, and its periphery is provided with the connecting screw hole that a plurality of equi-spaced apart are arranged.
Wherein: described the second flange connector is rectangular, its four bights are respectively equipped with positioning hole.
Known by said structure, the improved seal structure of press oil pipe of the present utility model has following technique effect:
1, simple in structure, adopted the double-layer sealing structure of O RunddichtringO and copper seal ring, good sealing effect, has avoided leakage;
2, by groove, carry out the fixing of sealing configuration, can not come off.
Detailed content of the present utility model can obtain by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the front view of the improved seal structure of the utility model press oil pipe;
Fig. 2 is the side view of the improved seal structure of the utility model press oil pipe;
Fig. 3 be in Fig. 2 A to view;
Fig. 4 is the enlarged diagram of B part in Fig. 2;
In figure, 11-standpipe, 12-transverse tube, 13-the first flange connector, 131-connecting screw hole, 14-the second flange connector, 141-positioning hole; The 15-portion that is tightly connected, 151-fixed groove, 16-combination seal.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described, following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figures 1 to 4, the concrete technological scheme of implementing of the utility model is: the improved seal structure of press oil pipe, the transverse tube 12 that oil pipe comprises vertically extending standpipe 11 and horizontal expansion, the lower end of described standpipe 11 is connected with the right-hand member of transverse tube 12, the upper end of described standpipe 11 is provided with the first flange connector 13, and the left end of described transverse tube 12 is provided with the second flange connector 14.
Wherein, described the second flange connector 14 laterally extends the portion 15 that is tightly connected, described in the portion 15 that is tightly connected can stretch in another oil pipe, described in the be tightly connected middle part periphery of portion 15 be provided with fixed groove 151, in described fixed groove 151, be provided with combination seal 16.
Wherein, referring to Fig. 4, described combination seal 16 comprises O RunddichtringO and the copper seal ring mutually reclining, thus, when sealing, copper seal ring can provide certain intensity, avoid O-ring seals transition deformation, thereby make combination seal 16 that sufficient sealing effect can be provided.
Wherein, referring to Fig. 3, described the first flange connector 13 is circular, and its periphery is provided with the connecting screw hole 131 that a plurality of equi-spaced apart are arranged.
Wherein, referring to Fig. 1, described the second flange connector 14 is rectangular, and its four bights are respectively equipped with positioning hole 141.
As can be seen here, the utility model has the advantage of:
1, simple in structure, adopted the double-layer sealing structure of O RunddichtringO and copper seal ring, good sealing effect, has avoided leakage;
2, by groove, carry out the fixing of sealing configuration, can not come off.
The above is only preferential mode of execution of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
