All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model aims to provide a pipeline connector with a self-locking device, which is used for solving the problems in the prior art, and when a product is subjected to external force such as vibration, the rotation of a rotating ring in the returning direction is prevented through the matching of a plug connector and a slot, so that the working stability of the pipeline connector is ensured.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As shown in fig. 1-4, the present embodiment provides a pipeline connector with a self-locking device, including a connector main body 1 and a rotating ring 2, wherein the rotating ring 2 is sleeved outside the connector main body 1, and the rotating ring 2 is provided with a quick-connection structure for screwing in a pipe joint connected thereto; in the embodiment, a french type pipeline connector is taken as an example for improvement, the quick connection structure is an intermittent protrusion 11 with a spiral side surface, a lug 12 for screwing the intermittent protrusion 11 into is arranged at the end part of the connector main body 1, and any quick connection structure which is assembled and disassembled by screwing in and screwing out is in the protection scope of the utility model;

the connector comprises a connector body 1, and is characterized in that a mounting seat 3 is arranged on a rotating ring 2, the mounting seat 3 can be detachable and fixed on the rotating ring 2 through a bolt 6, a jack is formed in the mounting seat 3 and penetrates from the outer end face of the mounting seat 3 to the inner surface of the rotating ring 2, a plug connector 4 capable of moving along the axis of the jack is arranged in the jack, an elastic resetting piece is arranged on the plug connector 4, a plurality of slots 8 matched with the plug connector 4 are circumferentially arranged on the outer wall of the connector body 1, and the cross section shape of the bottom of the plug connector 4 is matched with that of the slots 8, so that the plug connector 4 can be smoothly inserted into the slots 8, and the rotating ring 2 is prevented from returning; when the connector is installed, the rotating ring 2 is sleeved outside the connector main body 1, and the rotating ring 2 is rotated along the screwing direction, so that the discontinuous protrusions 11 on the rotating ring 2 are screwed into the lugs 12 on the connector main body 1 which are oppositely arranged on the other side and are gradually screwed, at the moment, the plug connector 4 is inserted into the slot 8, the elastic reset piece provides pressure for the plug connector 4 to be inserted into the slot 8 and tightly matched with the slot 8, and the rotating ring 2 is limited by the plug connector 4 and the slot 8 and cannot be retracted; when needs are dismantled, with plug connector 4 pull-up, plug connector 4 and slot 8 separation, at this moment, plug connector 4 no longer by slot 8 restriction, therefore swivel becket 2 can be followed and unscrewed the direction rotation, accomplishes the dismantlement work.

Furthermore, a unidirectional tooth structure 7 is arranged on the outer wall of the connector main body 1 along the circumferential direction, one side surface of the unidirectional tooth structure 7 is a surface vertical to the rotating direction, the other side surface is an inclined surface, a slot 8 is formed between the two unidirectional tooth structures 7, teeth 9 matched with the slot 8 are arranged at the bottom of the plug connector 4, and the shapes of the teeth 9 are the same as those of the slot 8; when the installation is started, after the rotating ring 2 is sleeved on the connector main body 1, the plug connector 4 can be inserted into the slot 8, the inclined plane of the tooth 9 is matched with the inclined plane of the slot 8, the vertical plane of the tooth 9 is matched with the vertical plane of the slot 8, when the rotating ring 2 needs to be screwed, the inclined plane of the tooth 9 and the inclined plane of the slot 8 move relatively, the plug connector 4 cannot obstruct the screwing-in action of the rotating ring 2, and after the installation is completed, under the action of external force, if the rotating ring 2 wants to retreat along the reverse direction, the vertical plane of the tooth 9 and the vertical plane of the slot 8 are in direct contact, so that the obstruction is formed, and the rotating ring 2 cannot retreat.

In this embodiment, the elastic reset piece selects spring 5, spring 5 is sleeved on plug connector 4, the 9 ends of teeth of plug connector 4 are provided with bosses, and spring 5 is located between the bosses and the outer end face of the jack.

Furthermore, a pull ring 10 is arranged at the end of the non-tooth 9 of the plug connector 4, a long groove 13 for accommodating the pull ring 10 is arranged on the end surface of the mounting base 3, and the direction of the long groove 13 is consistent with the direction of the pull ring 10 when the tooth 9 is inserted into the slot 8, in the embodiment, when the tooth 9 is inserted into the slot 8, the pull ring 10 is parallel to the end surface of the rotating ring 2, therefore, the length direction of the long groove 13 is also parallel to the end surface of the rotating ring 2, when the tooth 9 of the plug connector 4 needs to be inserted into the slot 8, the plug connector 4 falls down integrally, the pull ring 10 enters the long groove 13, and due to the limitation of the long groove 13 to the direction of the pull ring 10, the direction of the tooth 9 can be just aligned with the slot 8, so as to be inserted into the slot 8 accurately, thereby avoiding the situation that the tooth 9 and the slot 8 cannot be observed inside the device to cause poor alignment and insertion; when plug connector 4 is pulled up as required, plug connector 4 is pulled up through pull ring 10 to rotation 90, pull ring 10 is located the up end of mount pad 3 this moment, and the up end of mount pad 3 contacts with pull ring 10, thereby has restricted plug connector 4 and has moved downwards, thereby can be more convenient, smooth completion dismantlement work.

Furthermore, the corresponding locking marks that are arranged on the connector 4 and the rotating ring 2, and in the locking state, the locking marks are arranged at the corresponding positions on the same side of the connector 4 and the rotating ring 2, and because the connector body 1 is provided with the one-way tooth structure 7, the locking marks are arranged to enable the connector 4 to accurately find the locking position, so that the situation that the connector 4 cannot be smoothly inserted into the slot 8 due to the fact that the connector 4 rotates 90 degrees in the same direction instead of rotating 90 degrees when the connector is required to be connected is avoided.

Furthermore, the unidirectional tooth structure 7 can be arranged on the outer wall of the connector main body 1 in a whole circle or in a section, when only one section is arranged, the total circumferential length of the unidirectional tooth structure 7 is not less than the screwing-in stroke of the rotating ring 2, and the manufacturing cost of the pipeline connector can be reduced on the premise that the self-locking function can be guaranteed.

Furthermore, the width of the one-way tooth structure 7 is not less than the sum of the width of the teeth 9 and the axial displacement of the rotating ring 2, so that the teeth 9 are always matched with the slots 8 in the screwing process of the rotating ring 2.

Further, the connector comprises two sets of connector bodies 1 and rotating rings 2 which are arranged oppositely, when the connector is installed, the discontinuous protrusions 11 on the two rotating rings 2 are respectively screwed into the lugs 12 arranged on the connector body 1 on the opposite side, and the rotating rings 2 are locked on two sides to prevent the rotating rings from moving back and loosening.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
