[0034] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following, in combination with the attached drawings and preferred embodiments, details the specific implementation modes, structures, features, and effects of the direct insertion locking mechanism proposed according to the present utility model as follows.

[0035] Please refer to Figure 1, which is a schematic diagram of the structures of various parts of the direct insertion locking mechanism of the present utility model. The direct insertion locking mechanism includes a male head end and a female head end that are inserted into each other at the front end. The male head end includes a male head end housing 1, and the female head end includes a female head end housing 6 that is adapted to be inserted and mated with the male head end housing 1. An actuating ring 4 is provided on the outer periphery of the front end of the female head end housing 6, and the actuating ring 4 can slide back and forth along the axial direction of the female head end housing 6; a sliding ring 2 is further provided between the actuating ring 4 and the female head end housing 6, and the sliding ring 2 can slide back and forth along the axial direction of the female head end housing 6 relative to the female head end housing 6 and the actuating ring 4. An elastic member 5 that expands and contracts along the axial direction of the female head end housing 6 is further provided between the sliding ring 2 and the actuating ring 4, and the elastic member 5 can provide power for the sliding ring 2 to slide axially forward relative to the female head end housing 6, and provide power for the actuating ring 4 to move axially backward relative to the actuating ring 2 and the female head end housing 6. A first stop portion 61 for axially forward limiting the sliding ring 2 and a second stop portion 62 for axially backward limiting the actuating ring 4 are further provided on the female head end housing 6. The first stop portion 61 is used to prevent the sliding ring 2 from being disengaged from the front end of the female head end housing 6 under the action of the elastic member 5, and the second stop portion 62 is used to prevent the actuating ring 4 from being disengaged from the rear end of the female head end housing 6 under the action of the elastic member 5. In this embodiment, the elastic member is a spring, and the spring can be a cylindrical spring or a corrugated spring, etc.

[0036] A plurality of hole and groove structures are provided on the outer periphery of the front end of the sliding ring 2, and a locking member 3 is provided in the hole and groove structures, and the locking member 3 can move radially on the sliding ring 2. When the sliding ring 2 is axially forward blocked by the first stop portion 61 on the female head end housing 6 and the actuating ring 4 is axially backward blocked by the second stop portion 62, the inner peripheral surface of the front end of the actuating ring 4 is in sliding fit with the outer peripheral surface of the sliding ring 2 with a small gap. The locking member 3 is circumferentially limited by the inner peripheral surface of the front end of the actuating ring 4 and cannot move radially outward to protrude from the sliding ring 2. In this state, the surface of the actuating ring 4 that circumferentially limits the locking member 3 is defined as a locking surface 41, and the locking surface 41 is in contact with the outer peripheral end surface of the position where the locking member 3 is provided on the sliding ring 2. An avoidance groove 42 is further provided on the inner periphery of the front end of the actuating ring 4, and the avoidance groove 42 can provide a space for the locking member 3 to move radially outward to prevent the locking member 3 from interfering with the components entering the sliding ring 2.

[0037] A locking groove 11 for cooperating with the locking member 3 for locking is provided on the outer periphery of the front end of the male head end housing 1. When the male head end housing 1 is inserted and mated with the female head end housing 6 in place, the lower end of the locking member 3 falls into the locking groove 11. When there is no external force, under the action of the elastic member 5, the locking surface 41 on the actuating ring 4 radially limits the locking member 3, so that the locking member 3 is kept in the locking groove, thereby realizing the locking of the male head end and the female head end.

[0038] In this embodiment, the toggle ring 4 is slidably engaged with the sliding ring 2, and an inner boss 43 is provided on the inner circumference of the rear end of the toggle ring 4. The inner boss 43 is used to achieve axial stop and limit with the second stop portion 62 on the outer circumference of the female end housing 6. In this embodiment, the second stop portion 62 is an annular boss on the outer circumference of the female end housing 6. In other embodiments of the present invention, the second stop portion 62 can also be a stop structure fixed to the female end housing 6, such as a nut, a retaining ring, and a retaining plate. Preferably, the inner boss 43 also slides in contact with the outer circumference of the female end housing 6, but is not limited to this.

[0039] In this embodiment, the sliding ring 2 achieves axial forward stoppage through the cooperation of its inner circumferential protrusion and the first stopper 61 on the outer periphery of the front end of the female end housing 6. Preferably, the first stopper 61 is a protrusion on the outer periphery of the female end housing 6. In other embodiments of the present invention, the first stopper 61 can also be a stopper structure fixed to the female end housing 6.

[0040] In this embodiment, an annular protrusion is formed on the outer periphery of the front end of the sliding ring 2, and the locking member 3 is located in the hole groove feature on the annular protrusion. The locking surface 41 at the front end of the dial ring 4 slides in contact with the annular protrusion, thereby restricting the locking member 3 in the sliding ring 2 and preventing it from extending from the outer periphery of the sliding ring 2.

[0041] The outer circumference of the male end housing 1 is a stepped shaft structure with a small front and a large rear, and the small diameter section 12 at the front end of the male end housing 1 is used to adapt and plug with the female end housing 6, and the large diameter section 13 at the rear end is used to lock with the sliding ring 2 through the locking member 3. That is, the locking groove 11 is located on the outer circumference of the large diameter section 13 at the rear end of the male end housing 1. The small diameter section 12 and the large diameter section 13 of the male end housing 1 are connected by a transition section 14. When the male end and the female end are plugged into each other, the locking member 3, whose outer circumference is limited by the locking surface 41 on the toggle ring 4, is axially stopped and limited by the transition section 14 on the male end housing 11, so that the sliding ring 2 can move axially backward with the male end housing 1. When the locking member 3 on the sliding ring 2 moves to the position corresponding to the avoidance groove 42 on the toggle ring 4, the locking member 3 moves upward under the pressure of the transition section 14 and enters the avoidance groove 42. At the same time, the large diameter section 13 of the male end housing 1 Move to the bottom of the locking piece 3 and continue to push the male end housing 1. When the locking groove 11 on the male end housing 1 moves to the bottom of the locking piece 3, the locking piece 3 falls into the corresponding locking groove 11. At this time, the male end housing 1 is released. Under the action of the elastic piece 5, the sliding ring 2 drives the male end housing 1 to retreat until the sliding ring 2 is stopped by the first limit part. At this time, the locking surface 41 is located above the locking piece 3, limiting it circumferentially, so that the locking piece and the locking groove remain in the locked position.

[0042] In this embodiment, the transition section 14 is conical, that is, the small diameter section 12 and the large diameter section 13 are connected by a conical slope, so that when the male end shell is inserted into the female end, the transition section 3 can provide the locking part 3 with a force to move it upward into the avoidance groove 42, making the advancement of the male end more labor-saving and the insertion of the male end and the female end more labor-saving.

[0043] In this embodiment, the front end of the avoidance groove 42 also has a guiding slope for guiding the locking member 3 to enter, which can further reduce the insertion force between the male end and the female end.

[0044] In this embodiment, the locking groove 11 is a circular or rectangular annular groove. When the locking groove 11 is a rectangular annular groove, the front end of the rectangular annular groove is an inclined surface for guiding the locking member 3 to disengage and unlock, thereby reducing the unlocking force of the locking mechanism. Of course, in other embodiments of the present invention, the locking groove can also be a trapezoidal annular groove, etc.

[0045] In this embodiment, a guide structure for guiding the entry of the male end housing 1 is further provided on the inner side of the front end of the female end housing 6. Preferably, the guide structure is a chamfer.

[0046] In this embodiment, the male end housing 1 is an integrated structure. However, in other embodiments of the present invention, for ease of assembly, the male end housing 1 may also be a split structure consisting of two or more parts.

[0047] In this embodiment, the female end housing 6 and the sliding ring 2 are both integral structures, but in other embodiments of the present invention, for ease of assembly, the female end housing 6 and the sliding ring 2 may also be composed of two or more parts.

[0048] In this embodiment, the locking member 3 is a ball, but in other embodiments of the present invention, the locking member 3 may also be other structures.

[0049] When the direct plug locking mechanism of the utility model is in use, the action process of each component is described in detail as follows:

[0050] When the straight-insert locking mechanism is inserted and locked, it pushes the male end into the female end. When the male end is gradually inserted into the female end, the transition section 14 on the male end shell 1 will contact the locking piece 3 of the female end. At this time, the locking piece 3 is radially constrained by the locking surface 41 on the dial ring 4 and cannot be radially displaced in the sliding ring 2. Therefore, the male end shell 1 will push the locking piece 3 to move axially, and the locking piece 3 drives the sliding ring 2 to move axially. At this time, the sliding ring 2 further compresses the elastic piece 5.

[0051] When the locking piece 3 moves to the avoidance groove 42 on the toggle ring 4, the locking piece 3 is freed from the radial constraint of the locking surface 41 and will move radially under the push of the transition section 14 and enter the avoidance groove 42, thereby releasing the axial constraint between the male end housing 1 and the sliding ring 2, so that axial relative movement is generated between the male end housing 1 and the sliding ring 2. Since the locking piece 3 is blocked by the toggle ring 4, the sliding ring 2 cannot move forward under the action of the elastic piece.

[0052] When the locking groove 11 on the male end housing 1 moves to below the locking member 3, the locking member 3 is released from radial limitation, and under the action of the elastic member 5, the sliding ring 2 drives the locking member 3 to fall into the locking groove 11 on the male end housing. After loosening the male end housing 1, under the action of the elastic member 5, the sliding ring 2 drives the male end housing 1 to retreat together until the sliding ring 2 is axially limited by the first stop portion of the female end housing 6. At this time, the locking surface 41 of the toggle ring radially limits the locking member 3 to achieve locking between the male end and the female end; the whole process of straight insertion locking is now completed.

[0053] When unlocking the straight-insert locking mechanism, it is only necessary to move the toggle ring 4 toward the male end so that the avoidance groove 42 on the toggle ring 4 moves above the locking member 3, and the radial limit of the locking member 3 can be released. At this time, under the action of external force, the locking member 3 will radially enter the avoidance groove 42 from the locking groove 11, thereby realizing the unlocking and separation of the male end and the female end.

[0054] The straight-insert locking mechanism of the present invention can be a straight-insert locking connector. In this case, the male end is a connector plug and the female end is a connector socket.

[0055] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
