Referring to fig. 1 and 2, the present application provides a quick-plug structure 100 for metal pipes of an automobile, which is used when connecting metal pipes in an automobile, for example, connecting two metal pipes.

As shown in fig. 1, the metal pipe quick connect structure 100 for an automobile includes a male connector 10 and a female connector 20 that are inserted into each other. One of the female end fitting 20 or the male end fitting 10 is secured to an external metal pipe. Here, the female connector 20 is fixed to an external metal pipe, and the male connector 10 is used as a movable member for pre-mounting to a corresponding metal pipe, and then plugging with the female connector 20, thereby realizing connection between two metal pipes.

In an embodiment, the male connector 10 includes a body 11, a quick-insertion tube 12, a connecting tube 13, and a metal tube 14, wherein the quick-insertion tube 12 is disposed at one end of the body 11 and is connected with the female connector 20 in a plugging manner, the connecting tube 13 is disposed at the other end of the body 11, and the metal tube 14 is connected to one end of the connecting tube 13 far away from the body 11 for welding connection of an external metal pipeline. By means of the arrangement, the male connector 10 and the female connector 20 are in plug connection and matched, and finally, the two external metal pipelines are connected and communicated. It can be appreciated that, since the metal tube 14 is disposed on the male connector 10, the metal tube 14 can be directly welded with an external metal pipeline, and an additional component is not required to be added in a welding manner, so that the cost is reduced and the space occupied by the external metal pipeline during connection is reduced while the use of the component is reduced, thereby being beneficial to the arrangement of the internal pipeline of the automobile.

In one embodiment, the metal tube 14 is integrally provided with the connection tube 13, and the metal tube 14 is formed by flaring an end of the connection tube 13 away from the body 11 such that the inner diameter of the metal tube 14 is larger than the inner diameter of the connection tube 13. The metal tube 14 may be an iron tube, copper tube, steel tube, or the like. Of course, the metal tube 14 is preferably of the same material as the external metal tubing to be connected to facilitate a welded connection therebetween.

As shown in fig. 2, the connecting tube 13 includes a connecting section 131 and a connecting section 132, the connecting section 131 is bent, the connecting section 131 is connected with the body 11, the connecting section 132 is located between the connecting section 131 and the metal tube 14, one end of the connecting section 132 is connected with the connecting section 131, and the other end is connected with the metal tube 14. It should be noted that, the bending arrangement of the adaptor section 131 can change the orientation of the connection pipe 13, thereby facilitating the arrangement of the internal pipes of the automobile.

In one embodiment, the degree of curvature of adapter segment 131 is 90 degrees. Thus, the replacement direction of the installation of the external metal pipeline can be realized; at the same time, the size of the male end 10 as a whole in the axial direction of the main body 11 is reduced. Of course, the degree of bending of the adapter segment 131 may be 30 degrees, 45 degrees or 60 degrees, depending on the particular vehicle plumbing arrangement.

Specifically, a divergent pipe 133 is further disposed between the connecting pipe 13 and the metal pipe 14, one end of the divergent pipe 133 has the same diameter as the metal pipe 14, and the other end has the same diameter as the connecting pipe 13, and the surface of the divergent pipe 133 is changed in a straight line or an arc line, so that the liquid smoothly flows between the connecting pipe 13 and the metal pipe 14. That is, the diameter of the diverging pipe 133 gradually increases along the axis of the connecting pipe 13 in the direction from the connecting pipe 13 to the metal pipe 14.

It will be appreciated that by providing the diverging pipe 133, this also corresponds to forming a limiting step between the metal pipe 14 and the diverging pipe 133, thereby avoiding the external metal pipe from extending into the connecting pipe 13 in transition. And can also be positioned as a single piece to facilitate the welded connection between the metal tube 14 and the external metal piping.

As shown in fig. 1, a guiding structure 15 is provided between the male connector 10 and the female connector 20 to guide during the insertion movement between the male connector 10 and the female connector 20. The male connector 10 and the female connector can be conveniently connected in a pairing mode, and assembly efficiency is improved.

Specifically, the guiding structure 15 includes a guiding strip 151 and a guiding groove 152, one of the male terminal 10 and the female terminal 20 is provided with the guiding strip 151 on an outer sidewall, the other is provided with the guiding groove 152, and the guiding groove 152 extends along an axial direction of the male terminal 10 or the female terminal 20. In the plugging process of the male connector 10 and the female connector 20, the guide strip 151 can extend into the guide groove 152, so that the male connector 10 and the female connector 20 can be quickly and accurately plugged under the guidance of the guide groove 152. Here, the male connector 10 may be provided with a guide bar 151, and the female connector 20 may be provided with a guide groove 152. The male connector 10 may be provided with a guide bar 151, and the female connector 20 may be provided with a guide groove 152.

In this embodiment, the guide bar 151 is formed with a guide angle 153 inwardly contracted toward one end of the guide groove 152, and the guide angle 153 plays a role in guiding the insertion of the guide bar 151 into the guide groove 152, so that the insertion of the guide bar 151 into the guide groove 152 is facilitated, and the assembly process is more convenient.

It is understood that the guiding structure 15 is not limited to the above-mentioned structure of the guiding strip 151 and the guiding groove 152, and may be configured as a type structure as long as guiding during the plugging process of the two structures can be achieved.

As shown in fig. 1 and 2, a locking structure 16 is arranged between the male connector 10 and the female connector 20, and the locking structure 16 is used for locking after the male connector 10 and the female connector 20 are inserted.

In one embodiment, the latch structure 16 includes a latch 161, a first latch slot 162 and a second latch slot 163, the first latch slot 162 is located on an outer sidewall of the female terminal 20 and is in communication with the interior of the female terminal 20, and the second latch slot 163 is open on an outer sidewall of the male terminal 10 and corresponds to the first latch slot 162. After the male terminal 10 and the female terminal 20 are inserted, part of the lock catch 161 is located in the first locking groove 162, and the other part of the lock catch is clamped into the second locking groove 163 through the first locking groove 162, so that locking between the male terminal 10 and the female terminal 20 is achieved.

Specifically, the lock catch 161 is in a U shape, the lock catch 161 is provided with a lock body 161a and two lock arms 161b, the two lock arms 161b are symmetrically arranged at two ends of the lock body 161a and form a U shape together with the lock body 161a, and the lock arms 161b can elastically deform relative to the lock body 161a under the action of external force. When the latch 161 is installed on the outer sidewall of the female terminal 20, the latch arm 161b expands under the compression of the outer peripheral wall of the female terminal 20; then, with the continued movement of the lock catch 161, the lock arm 161b is reset, and at this time, the lock arm 161b is snapped into the second lock groove 163 through the first lock groove 162, and another portion abuts against the side wall of the first lock groove 162 along the axial direction of the female connector 20, so as to form a limit. This achieves a locking between the male end 10 and the female end 20.

Further, a limiting portion 164 is disposed at one end of each locking arm 161b away from the lock body 161a, a third limiting groove 21 is further disposed on the outer wall of the female connector 20, and the third limiting groove 21 is located at the middle position of the female connector 20. When the lock catch 161 is erected on the outer peripheral wall of the female connector 20, the limit portion 164 abuts against the outer peripheral wall of the female connector 20. The limit portion 164 can enter the third limit groove 21 or move out of the third limit groove 21 along with the movement of the lock body 161a, thereby unlocking the male terminal 10 and the female terminal 20.

It will be appreciated that the movement of the shackle 161 to the female connector 20 may be divided into three processes, the first of which is the movement of the locking arm 161b, which is the outward expansion of the locking arm 161b relative to the lock body 161a (in the radial direction of the female connector 20) as the shackle 161 moves. In the second process, when the lock arm 161b moves to the horizontal position of the female terminal 20, i.e., the middle position of the female terminal 20, the outward expansion position of the lock arm 161b is the largest, i.e., the deformation degree is the largest. In the third stage, as the lock catch 161 moves continuously, the lock arm 161b is reset, and at this time, part of the lock arm 161b is also snapped into the second lock slot 163 from the first lock slot 162.

Therefore, when the limiting portion 164 moves into the third limiting groove 21, the locking arm 161b moves from the third process to the second process, and at this time, the locking arm 161b moves from the second locking groove 163 into the first locking groove 162, thereby releasing the locking between the female terminal 20 and the male terminal 10. In contrast, when the stopper 164 is disengaged from the third stopper groove 21 to abut against the outer peripheral wall of the female terminal 20, the lock arm 161b undergoes a movement from the second process to the third process, and locking between the female terminal 20 and the male terminal 10 is effected. In this way, a quick unlocking and locking between the female end 20 and the male end 10 can be achieved.

As shown in fig. 2, the body 11 is provided with a plurality of weight-reducing grooves 111, and the plurality of weight-reducing grooves 111 are arranged at intervals along the circumferential direction of the body 11, so that the weight of the body 11 is reduced as much as possible. Specifically, the number of the weight-reducing grooves 111 may be 4, 6, or 8. In the present embodiment, the weight-reducing groove 111 is provided as a square groove, but of course, the weight-reducing groove 111 may be provided in other shapes, such as a triangle, a circle, and the like.

The application also provides a technical scheme as follows:

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
