Description
Technical field
The utility model belongs to mechanical assembly technique, relates to the improvement to the gland nut of connecting tube joint.
Background technique
The structure of the gland nut of present a kind of connecting tube joint is referring to Fig. 1, it is the nut 3 that a right-hand member opens wide, left end has internal shoulder 3a, outside thread on the convex shoulder 2a of the internal thread of nut 3 and the pipe joint 2 that has inner conical surface matches, and the center hole of internal shoulder 3a is greater than the external diameter of pipe of the pipe joint 1 that has male cone (strobilus masculinus) and less than the external diameter of the pipe joint 1 convex shoulder 1a that has male cone (strobilus masculinus).During use, the center hole of nut 3 internal shoulder 3a is enclosed within on the pipe joint 1 that has male cone (strobilus masculinus), and the outside thread engagement on the internal thread of nut 3 and the convex shoulder 2a of pipe joint 2 that has inner conical surface makes the inner conical surface of pipe joint 1 male cone (strobilus masculinus) and pipe joint 2 fit to form and seals.Its shortcoming is: the dismounting and change difficulty of gland nut.This gland nut can only be in the situation of open state for an other end of pipe joint, when the other end of pipe joint when other structure is connected, because nut 3 can't be enclosed within on the pipe joint 1 that has male cone (strobilus masculinus), therefore can't finish and being connected of pipe joint 2.In addition, when the pipe joint that has connected needs dismounting and change nut 3, whole pipeline all must be disassembled, otherwise nut 3 also can't take out from pipe joint 2.Above-mentioned shortcoming brings difficulty for the maintenance and repair of equipment, has increased maintenance cost.
Summary of the invention
The purpose of this utility model is: propose a kind of gland nut of the connecting tube joint that is easy for installation and removal, with the maintenance and repair difficulty of simplified apparatus, reduce maintenance cost.
The technical solution of the utility model is: a kind of gland nut of connecting tube joint is characterized in that it is made up of swivel nut 4, baffle ring and 4～8 countersunk head lock screws 6; The outer surface of swivel nut 4 is outer six sides, and the outside thread on the convex shoulder 2a of the internal thread of swivel nut 4 and the pipe joint 2 that has inner conical surface matches, and 4～8 tapped blind holes that are uniformly distributed along the circumference are arranged in the left side of swivel nut 4; Baffle ring is combined to form by two half identical baffle rings 5 of structure, the diameter of bore of baffle ring is greater than the external diameter of pipe of the pipe joint 1 that has male cone (strobilus masculinus) and less than the external diameter of the pipe joint 1 convex shoulder 1a that has male cone (strobilus masculinus), the outer surface of baffle ring is outer six sides corresponding with the outer surface of swivel nut 4, the sunk screw via hole that quantity is identical and the position is corresponding of tapped blind hole on quantity and the swivel nut 4 is arranged in the left side of baffle ring, and countersunk head lock screw 6 is fixed on baffle ring on the left side of swivel nut 4.
The utility model has the advantages that: can mount and dismount the gland nut of connecting tube joint easily, simplify the maintenance and repair difficulty of equipment, reduce maintenance cost.
Description of drawings
Fig. 1 is the structural representation of the gland nut of present a kind of connecting tube joint.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below the utility model is described in further details.Referring to Fig. 2, a kind of gland nut of connecting tube joint is characterized in that, it is made up of swivel nut 4, baffle ring and 4～8 countersunk head lock screws 6; The outer surface of swivel nut 4 is outer six sides, and the outside thread on the convex shoulder 2a of the internal thread of swivel nut 4 and the pipe joint 2 that has inner conical surface matches, and 4～8 tapped blind holes that are uniformly distributed along the circumference are arranged in the left side of swivel nut 4; Baffle ring is combined to form by two half identical baffle rings 5 of structure, the diameter of bore of baffle ring is greater than the external diameter of pipe of the pipe joint 1 that has male cone (strobilus masculinus) and less than the external diameter of the pipe joint 1 convex shoulder 1a that has male cone (strobilus masculinus), the outer surface of baffle ring is outer six sides corresponding with the outer surface of swivel nut 4, the sunk screw via hole that quantity is identical and the position is corresponding of tapped blind hole on quantity and the swivel nut 4 is arranged in the left side of baffle ring, and countersunk head lock screw 6 is fixed on baffle ring on the left side of swivel nut 4.
Using method of the present utility model is: if need an other end of the pipe joint that has male cone (strobilus masculinus) of connection to be in the situation of open state, baffle ring and swivel nut are locked with the countersunk head lock screw, an end that is in open state from the pipe joint that has male cone (strobilus masculinus) is inserted in, and swivel nut is connected with the pipe joint outside thread that has inner conical surface that needs to be connected to get final product then.If need an other end of the pipe joint that has male cone (strobilus masculinus) of connection to be in the state that connects or seal, at first swivel nut is inserted in from the pipe joint that has male cone (strobilus masculinus), and then baffle ring and swivel nut locked with the countersunk head lock screw, swivel nut is connected with the pipe joint outside thread that has inner conical surface that needs be connected get final product at last.
An embodiment of the present utility model has 6 tapped blind holes that are uniformly distributed along the circumference in the left side of swivel nut 4, and 6 sunk screw via holes are arranged in the left side of baffle ring, and their position is corresponding with 6 tapped blind holes on swivel nut 4 left sides respectively.
