However, when the existing flange is installed and fixed, only a gasket is generally arranged, and other effective anti-loosening measures are lacked, so that the problem of looseness of the bolt is easy to occur after the bolt is assembled, and further medium leakage is caused.
SUMMERY OF THE UTILITY MODEL
To the not enough in the background art, the utility model provides a locking steel pipe flange.
The utility model adopts the technical proposal that: the utility model provides a locking steel pipe flange, includes left steel pipe, right steel pipe, left flange dish and right flange dish, be equipped with the fixed orifices on left flange dish and the right flange dish, left flange dish and right flange dish link firmly through hex bolts, still include the stabilizer ring, be equipped with the hexagon through-hole in the middle of the stabilizer ring, the both ends of stabilizer ring are equipped with the restriction strip, the tip of the fixed orifices of left flange dish and right flange dish all is equipped with the flaring, the both sides of flaring be equipped with above-mentioned restriction strip assorted restriction groove, form the embedded groove that is used for the stabilizer ring embedding between the spiral shell head or the nut of flaring outer wall and hex bolts.
Furthermore, the screw head and the nut of the hexagon bolt are both of an equihexagonal structure.
Furthermore, the limiting groove is provided with a linear groove crossed with the limiting groove, and the depth of the linear groove is greater than that of the limiting groove.
Further, the stabilizing ring and the limiting strip are integrally formed.
Further, the stabilizing ring and the restraining strip are made of plastic.
The utility model has the advantages that: the utility model discloses an increase the flaring on original ring flange, form the embedded groove between the spiral shell head or the nut of flaring and bolt, install the stationary ring that has the restriction strip on the embedded groove, the restriction strip card of stationary ring goes into the restriction inslot at flaring both ends to restriction bolt rotation appears the not hard up problem of bolt after avoiding assembling, improves the stability and the reliability of connecting.
In addition to the objects, features and advantages described above, other objects, features and advantages of the present invention are also provided.
The present invention will be described in further detail below with reference to the drawings.
Drawings
Fig. 1 is a schematic cross-sectional view of the present invention.
Fig. 2 is a left side view of the present invention.
FIG. 3 is a schematic view of a stabilizing ring
In the figure: 1. a left steel tube; 2. a right steel tube; 3. a left flange plate; 4. a right flange plate; 5. a fixing hole; 6. a hexagon bolt; 7. a stabilizing ring; 8. a through hole; 9. a restriction strip; 10. flaring; 11. a limiting groove; 12. a groove is embedded; 13. a straight slot.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.
The utility model provides a locking steel pipe flange.
In this embodiment, refer to fig. 1 to 3, this locking steel pipe flange, including left steel pipe 1, right steel pipe 2, left flange 3 and right flange 4, be equipped with fixed orifices 5 on left flange 3 and the right flange 4, left flange 3 and right flange 4 link firmly through hex bolts 6, still include stabilizer ring 7, be equipped with hexagon through-hole 8 in the middle of stabilizer ring 7, stabilizer ring 7's both ends are equipped with restriction strip 9, the tip of the fixed orifices of left flange 3 and right flange 4 all is equipped with flaring 10, the both sides of flaring 10 be equipped with above-mentioned restriction strip assorted restriction groove 11, form the embedded groove 12 that is used for stabilizer ring embedding between 10 outer walls of flaring and the spiral shell head or the nut of hex bolts.
Among the above-mentioned technical scheme, through increasing the flaring on the ring flange originally, form the embedded groove between the spiral shell head or the nut of flaring and bolt, install the stabilizer ring that has the restriction strip on the embedded groove, the restriction strip card of stabilizer ring is gone into in the restriction groove at flaring both ends to restriction bolt rotation avoids appearing the not hard up problem of bolt after the equipment, improves the stability and the reliability of connecting.
The utility model discloses a in the time of, link firmly two ring flanges with hexagon bolt earlier, then imbed the stable ring 7 in the embedded groove that forms between flaring and nut and flaring and spiral shell head, can restrict the stable ring and rotate owing to be provided with the restriction strip on the stable ring to the restriction bolt rotation improves the stability of connecting.
Specifically, the head and the nut of the hexagon bolt are both of an equihexagonal structure.
Specifically, the limiting groove is provided with a straight groove 13 crossed with the limiting groove, and the depth of the straight groove 13 is greater than that of the limiting groove. When the stabilizing ring needs to be disassembled, the rod-shaped body can be extended into the straight groove to tilt the stabilizing ring, and then the stabilizing ring can be disassembled by a wrench. The straight groove is mainly arranged to facilitate the removal of the stabilizing ring.
Specifically, the stabilizing ring and the limiting strip are integrally formed; the stabilizing ring and the restraining strip are made of plastic. The integrally formed stabilizing rings and the limiting strips have better mechanical strength, are convenient for batch matched production, and reduce the cost. In addition, the stabilizing ring and the limiting strip are made of plastics, so that the cost can be reduced, the stabilizing ring can be directly destroyed to be detached under the condition that the stabilizing ring cannot be taken out after long-term use, and the stabilizing ring can be reinstalled during assembly, so that the use is convenient.
The skilled person should understand that: although the present invention has been described in terms of the above embodiments, the inventive concepts are not limited to the embodiments, and any modifications that utilize the inventive concepts are intended to be included within the scope of the appended claims.
