Abstract
A connection device comprises an internal screw assembly and an external screw assembly, wherein the internal screw assembly is composed of an internal screw piece (1), a positioning ring (2), a clamp ring (3), six springs (4) and a shell (5); the external screw assembly is composed of a seal ring (6) and an external screw piece (7). The anti-loosing device is composed of the positioning ring (2), the clamp ring (3), the spring (4) and the shell (5). Three uniformly distributed grooves (B) are arranged on the positioning ring (2) and three correspondingly uniformly distributed bosses (A) are arranged on the clamp ring. When the internal screw piece is screwed with the external screw piece, the positioning is performed by the key (C) on the shell (5) and the key groove (D) on the external screw piece (7) to realize the relative fixation of the shell (5) and the external screw piece (7). The device is suitable for coupling the quick carry-over moment and quick coupling and uncoupling of the screw connection and is used for optical and electric connectors, a gas and liquid pipeline connector.
Description
Affiliated technical field
The utility model relates to a kind of being threaded and locking device, and this device is suitable for the quick joint and the disengagement of threaded connector, can be used for electric coupler, gas and fluid pipeline connector.
Background technique
Known square threaded form connection set with connection and release function, general by rotation internal thread or outside thread realization, be fit to use in some big threaded connection occasions, but the speed of these device rotations is slower, there is not locking device simultaneously, in vibration environment, screw thread has the possibility of release.From the use angle of product, in some important occasions, this product does not possess locking device, and operational safety is lower.
Summary of the invention
The utility model provides a kind of new double end rectangle to connect fast and locking device.The quick linkage function that realizes product that screws by internal and external threads spare, this device adopts double end square threaded form structure, and the speed of screwing that improves product reaches one times, the quick connection of implement device, by the effect of hold-down ring and positioning ring and spring, realize that product screws the locking functions after putting in place.This worm structure can carry bigger moment, is fit to use in bigger moment occasion.
The technical solution adopted in the utility model is: this connection set comprises outside thread assembly and threaded component, and the outside thread assembly is made up of seal ring and external thread piece, and threaded component is made up of inner thread piece, positioning ring, hold-down ring, spring, housing.Wherein positioning ring, hold-down ring, spring are contained between housing and the inner thread piece, spring is contained between inner thread piece and the positioning ring, and after the assembling certain pretightening force is arranged, design has boss on hold-down ring, design is fluted on positioning ring, during assembling, the boss on the hold-down ring matches with groove on the positioning ring.Simultaneously, design is fluted on external thread piece, design has protruding key on housing, when this device screws, at first the protruding key on the housing is inserted the groove of external thread piece, its the two relative position is fixed, when the rotation inner thread piece, make the external thread piece rotation relatively together of inner thread piece, positioning ring, spring, thereby reach purpose of connecting, connect when putting in place, the boss on the product hold-down ring just in time falls into the groove on the positioning ring; During the product release, at first will overcome the elastic force that spins out the groove of boss from positioning ring on the hold-down ring, this elastic force is produced by spring, thereby reaches the purpose that prevents the screw thread release.
The utility model has the advantages that: this connection set has been realized the quick purpose of connecting of the big moment of transmission, and connection speed doubles, and simultaneously, the defective that having overcome is threaded frees has easily improved connection reliability, and is simple to operation.Simultaneously, have seal ring on this connection set, can be out of doors, use in the water, play good waterproof effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the sectional drawing of connection set, has represented the threaded component insertion outside thread assembly relation of each several part before.
Sectional drawing when Fig. 2 rotates from the groove of positioning ring for the boss of hold-down ring in the threaded component.

Among the figure: 1. inner thread piece, 2. positioning ring, 3. hold-down ring, 4. spring, 5. housing, 6. seal ring, the boss on the 7 external thread piece A. hold-down rings, the groove on the B. positioning ring, the key on the C. housing, the keyway on the D. external thread piece.
Embodiment
In Fig. 1～Fig. 2, this connection set comprises threaded component (1～5) and outside thread assembly (6～7), threaded component (1～5) is made up of inner thread piece (1), positioning ring (2), hold-down ring (3), spring (4), housing (5), and outside thread assembly (6～7) is made up of seal ring (6) and external thread piece (7).Spring (4) is installed between inner thread piece (1) and the positioning ring (2), then, boss (A) on the hold-down ring (3) is pressed into the groove (B) on the positioning ring, simultaneously, step on the housing (5) is pushed down hold-down ring (3), guarantees that spring (4) is a pressurized between inner thread piece (1) and positioning ring (2).When this mechanism connects, at first in the inner thread piece that turns clockwise (1), drive hold-down ring (A) rotation together, at this moment, need overcome the pressure that is subjected to spring (4) when boss (A) on the hold-down ring groove (B) from positioning ring screws out, connect when putting in place, the boss on the hold-down ring (A) falls into the groove (B) on the positioning ring again, have tangible feel this moment or hear " " one, show that product connects to put in place; During this mechanism release, need be rotated counterclockwise inner thread piece (1), inner thread piece (1) drives positioning ring (2) rotation, at this moment, need overcome the elastic force of the spring (4) that rotates the groove (B) of boss (A) from positioning ring on the hold-down ring, fall into groove (B) on the positioning ring again until the boss on the hold-down ring (A), show the release of this mechanism.
At present, square threaded form does not also have standard, when practical application, can select with reference to the diameter and the pitch (GB5796.3-86) of trapezoidal thread the diameter and the pitch of metric system square threaded form, can design voluntarily according to actual needs yet.
Key (C) on the device middle shell described in the utility model can use power transmission parts such as pin, screw to replace.
