Abstract
The invention relates to a flange connection device which comprises a first flange and a second flange, wherein a first sleeve is fixedly arranged on the first flange, a second sleeve is fixedly arranged on the second flange, the first sleeve is inserted into the second flange, an outer thread is arranged on the outer wall of the first sleeve, and an inner thread matched with the outer thread is arranged on the inner wall of the second sleeve. A plurality of assembly blind holes are formed between the outer thread of the first sleeve and the first flange, each assembly blind hole is perpendicular to the axial direction of the first flange, and the assembly blind holes are positioned on the same radial plane of the first sleeve. A limit groove is formed in the outer side of the inner thread of the second sleeve, and an elastic limit mechanism for being clamped into the limit groove is arranged in each assembly blind hole. The flange connection device is simple in structure, reasonable in design and capable of ensuring firm connection of the two flanges and long firm connection.
Description
Technical field
The present invention relates to a kind of flange connecting apparatus.
Background technique
In prior art, by two Flange joint to time together, adopt connecting bolt to be fixed connection, although such Placement is more firm, service time long afterwards, just can cause connectivity robustness to reduce, and impact normally uses.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of structure simple, reasonable in design, the firm connection of two flanges can be ensured and connect firm flange connecting apparatus of a specified duration.
Realize technological scheme of the present invention as follows:
Flange connecting apparatus, comprise the first flange, second flange, first flange is fixedly installed the first sleeve pipe, second flange is fixedly installed the second sleeve pipe, described first sleeve pipe inserts in the second sleeve pipe, the outer wall of the first sleeve pipe is provided with outside thread, the inwall of the second sleeve pipe is provided with the internal thread coordinated with outside thread, outside thread on the first sleeve pipe and be provided with multiple assembling blind hole between the first flange, each assembles, and blind hole is vertical with the axial direction of the first flange to be arranged, and each assembling blind hole is in the same radial plane of the first sleeve pipe, restraining groove is offered outside the internal thread of the second sleeve pipe, the elastic spacing mechanism for snapping in above-mentioned restraining groove is provided with in each assembling blind hole.
Have employed technique scheme, when assembling two flanges, first screw thread is adopted to be connected the first sleeve pipe and the second sleeve pipe, a half is threaded onto at the two, the compression that elastic spacing mechanism is subject to the second sleeve pipe is shunk in assembling blind hole, and then the first sleeve pipe, the second sleeve pipe continue to be threaded, after being threaded and putting in place, elastic spacing mechanism then can stretch in restraining groove, realizes spacing object like this.
Further, described elastic spacing mechanism comprises the spring be arranged in assembling blind hole, and the limit body of Compress Spring, in the deep enough restraining groove of this limit body energy.
Further, in order to make, limit body is smooth and easy enters assembling blind hole, and the oral area of described assembling blind hole is cone structure.
Further, described first flange adopts connecting bolt to be fixedly connected with the periphery of the second flange.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
See Fig. 1, flange connecting apparatus, comprise the first flange 1, second flange 2, first flange is fixedly installed the first sleeve pipe 3, second flange is fixedly installed the second sleeve pipe 4, first sleeve pipe inserts in the second sleeve pipe, the outer wall of the first sleeve pipe is provided with outside thread 5, the inwall of the second sleeve pipe is provided with the internal thread 6 coordinated with outside thread, outside thread on the first sleeve pipe and be provided with multiple assembling blind hole 7 between the first flange, each assembles, and blind hole is vertical with the axial direction of the first flange to be arranged, and each assembling blind hole is in the same radial plane of the first sleeve pipe, restraining groove 8 is offered outside the internal thread of the second sleeve pipe, the elastic spacing mechanism for snapping in above-mentioned restraining groove is provided with in each assembling blind hole.Wherein, elastic spacing mechanism comprises the spring 9 be arranged in assembling blind hole, and the limit body 10 of Compress Spring, and in the deep enough restraining groove of this limit body energy, limit body is spheroid.The oral area 11 of assembling blind hole is cone structure.First flange adopts connecting bolt 12 to be fixedly connected with the periphery of the second flange.Second sleeve pipe 4 having the dismounting through hole 13 be communicated with restraining groove 8, like this when dismantling, being convenient to, by inserting cylinder compression limit body in dismounting through hole, limit body be shunk in assembling blind hole, is convenient to mounting or dismounting like this.Be enlarging 14 in the end of the second sleeve pipe, be convenient to the handling of limit body.
