Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a connector that is easy to lock and unlock. Background Art

[0002] At present, after the connected body is docked with the connector joint, the threaded connection between the nut on the connector joint and the connected body is usually used to lock the connected body. During the locking and unlocking process, the nut needs to be rotated several times, and sometimes tools such as wrenches are needed. This undoubtedly has the defects of low efficiency and inconvenient operation. After long-term use, the nut will become loose, causing the connector joint to separate from the connected body. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a connector joint that is easy to lock and unlock, which can quickly, conveniently and reliably realize locking and unlocking between the connector joint and the connected body.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a connector joint that is easy to lock and unlock, comprising:

[0005] shell;

[0006] A screw sleeve is axially movably mounted on the housing;

[0007] an elastic body, disposed between the housing and the screw sleeve, and configured to be supported by the screw sleeve during the process of the screw sleeve moving toward the housing to allow the connected body to pass over it, and to abut against the connected body that has passed over it after the elastic body and the screw sleeve are reset in the axial direction to prevent the connected body from being separated;

[0008] The locking assembly is adapted to lock the relative positions of the screw sleeve and the housing in the axial direction after the screw sleeve is reset in the axial direction.

[0009] A specific structure of a locking assembly with a simple structure is further provided, wherein the locking assembly includes a limiting pin and a limiting groove used in conjunction with each other, one of which is provided on the housing and the other is provided on the screw sleeve, and the limiting groove includes an axial groove and a circumferential groove that are interconnected; wherein,

[0010] During the movement of the screw sleeve toward the housing, the limit pin moves in the axial groove. After the screw sleeve is reset in the axial direction, the limit pin faces the opening of the circumferential groove and can enter the circumferential groove.

[0011] In order to further ensure that the sleeve can automatically reset after the connected body passes over the elastomer, the locking assembly also includes an elastic member, which is arranged between the sleeve and the shell and is suitable for being compressed during the movement of the sleeve toward the shell and driving the sleeve to reset during its reset process.

[0012] The specific structure of another locking assembly with a simple structure is further provided, wherein the locking assembly includes a limit pin and a limit groove used in conjunction with each other, one of which is provided on the outer shell and the other is provided on the screw sleeve, and the limit groove is an inclined groove, which is used to cooperate with the limit pin during the rotation of the screw sleeve to cause the screw sleeve to be displaced in the axial direction.

[0013] A specific structure of an elastic body that is easily expanded is further provided, wherein the elastic body is a non-closed ring body.

[0014] Furthermore, the elastic body has an inner conical surface, and the screw sleeve moves along the inner conical surface of the elastic body in the process of moving toward the outer shell to expand the elastic body.

[0015] Furthermore, the outer shell has an outer ring body and an inner ring body that are spaced apart from each other. The outer ring body is provided with an annular groove opening toward the inner ring body, and the elastic body is located in the annular groove.

[0016] In order to further achieve a sealed connection between the connector joint and the connected body, the outer wall of the inner ring body is provided with an O-ring groove, and an O-ring is arranged in the O-ring groove.

[0017] In order to further prevent the elastic member from shifting, the screw sleeve includes an outer sleeve and an inner sleeve that are connected to each other, and a space is left between the inner circumferential wall of the outer sleeve and the outer circumferential wall of the inner sleeve. The elastic member is located in the space, and the free end of the inner sleeve supports the elastomer during the movement of the screw sleeve toward the outer shell.

[0018] Furthermore, the connector joint that is easy to lock and unlock further includes an insulator and a pin, wherein the insulator and the pin are respectively installed in the shell, and the insulator is separated between the pin and the shell.

[0019] After adopting the above technical solution, the screw sleeve moves toward the shell side in the axial direction, stretching the elastomer, and the connecting part of the connector passes over the elastomer and enters the space in front of the elastomer. Then, after the screw sleeve is reset in the axial direction, the elastomer loses the extrusion of the screw sleeve and is also reset. After the reset, the opening becomes smaller and blocks the rear side of the connecting part of the connected body, thereby preventing the connected body from detaching from the connector joint. Finally, the relative position of the screw sleeve and the shell in the axial direction is locked by the locking assembly, so that the screw sleeve cannot move toward the shell, thereby achieving locking between the connector joint and the connected body; the locking assembly is released, the screw sleeve moves toward the shell side, stretching the elastomer, and the connected body can be withdrawn from the connector joint. This embodiment can conveniently and reliably achieve locking and unlocking between the connector joint and the connected body, with high efficiency and easy operation.

[0028] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0029] like Figure 1-7 As shown, a connector joint that is easy to lock and unlock, comprising:

[0030] Shell 1;

[0031] The screw sleeve 2 is axially movably mounted on the housing 1;

[0032] The elastic body 4 is provided between the housing 1 and the screw sleeve 2 and is configured to be supported by the screw sleeve 2 during the movement of the screw sleeve 2 toward the housing 1 to allow the connected object to pass over it, and to abut against the connected object that has passed over it after the elastic body 4 and the screw sleeve 2 are reset in the axial direction to prevent the connected object from being separated;

[0033] The locking assembly is suitable for locking the relative positions of the screw sleeve 2 and the housing 1 in the axial direction after the screw sleeve 2 is reset in the axial direction.

[0034] Specifically, the screw sleeve 2 moves toward the side of the shell 1 in the axial direction, stretching the elastomer 4, so that the connecting portion of the connector passes over the elastomer 4 and enters the space in front of the elastomer 4, and then after the screw sleeve is reset in the axial direction, the elastomer 4 loses the extrusion of the screw sleeve 2 and is also reset. After the reset, the opening becomes smaller and blocks the rear side of the connecting portion of the connected body, thereby preventing the connected body from detaching from the connector joint, and finally the relative position of the screw sleeve 2 and the shell 1 in the axial direction is locked by the locking assembly, so that the screw sleeve cannot move toward the shell, thereby achieving the locking between the connector joint and the connected body; the locking of the locking assembly is released, the screw sleeve 2 moves toward the side of the shell 1, stretching the elastomer 4, and the connected body can be withdrawn from the connector joint. This embodiment can conveniently and reliably achieve the locking and unlocking between the connector joint and the connected body, with high efficiency and easy operation.

[0035] There are many possible structures for the locking assembly, two of which are listed below.

[0036] The first one, such as Figure 1 、 2 As shown in FIG3 , the locking assembly includes a stop pin 5 and a stop slot 9 used in conjunction with each other, one of which is provided on the housing 1 and the other is provided on the screw sleeve 2. The stop slot 9 includes an axial slot 91 and a circumferential slot 92 that are interconnected; wherein,

[0037] When the screw sleeve 2 moves toward the housing 1 , the limit pin 5 moves in the axial groove 91 . After the screw sleeve 2 is reset in the axial direction, the limit pin 5 faces the opening of the circumferential groove 92 and can enter the circumferential groove 92 .

[0038] Specifically, after the connected body and the connector joint are plugged in and docked, the limit pin 5 is screwed into the circumferential groove 92 from the opening of the circumferential groove 92, thereby locking the relative positions of the screw sleeve 2 and the shell 1 in the axial direction, thereby locking the connector joint and the connected body; when unlocking is required, the limit pin 5 is screwed into the axial groove 91 from the opening of the circumferential groove 92, and the screw sleeve 2 can be moved toward the side of the shell 1 to achieve unlocking. The entire locking assembly is simple and reliable.

[0039] In order to automatically reset the screw sleeve 2 after the connected body passes over the elastic body 4 in the axial direction, the locking assembly may further include an elastic member 3, which is arranged between the screw sleeve 2 and the housing 1 and is suitable for being compressed during the movement of the screw sleeve 2 toward the housing 1 and driving the screw sleeve 2 to reset during its reset process. The elastic member 3 may be a spring or the like.

[0040] Among them, Figure 2 As shown, the screw sleeve 2 includes an outer sleeve 21 and an inner sleeve 22 connected to each other. A space is left between the inner circumferential wall of the outer sleeve 21 and the outer circumferential wall of the inner sleeve 22. The elastic member 3 is located in the space. As the screw sleeve 2 moves toward the housing 1, the free end of the inner sleeve 22 expands the elastic member 4. This arrangement can effectively constrain the position of the elastic member 3 and prevent it from shifting.

[0041] The second type, such as Figure 4 、 5 As shown in Figures 6 and 7, the locking assembly includes a limiting pin 5 and a limiting groove 9 used in conjunction with each other. One of the limiting pins 5 is provided on the housing 1, and the other is provided on the screw sleeve 2. The limiting groove 9 is an inclined groove, which is used to cooperate with the limiting pin 5 during the rotation of the screw sleeve 2 to cause the screw sleeve 2 to move in the axial direction.

[0042] Among them, the limiting groove 9 and the end face of the screw sleeve 2 are Figure 3 The angle between the lines formed by the viewing angle is 2-3 degrees.

[0043] Specifically, after adopting this locking assembly, the axial displacement of the screw sleeve 2 relative to the shell 1 can be achieved during the rotation of the screw sleeve 2, and the screw sleeve 2 can be fixed in the position of the stretched elastomer 4 through the cooperation of the limit groove 9 and the limit pin 5, thereby facilitating the connection between the connector joint and the connected body.

[0044] In one embodiment, Figure 7 As shown, the elastic body 4 is a non-closed annular body having an inner conical surface 41 , and the screw sleeve 2 moves along the inner conical surface 41 of the elastic body 4 in the process of moving toward the housing 1 to expand the elastic body 4 .

[0045] The elastic body 4 of this structure is easy to deform elastically, is convenient to be stretched, and can also be easily reset. The structure of the elastic body 4 is not limited to the above description, and can also include an annular ring and a plurality of elastic petals spaced apart on the annular ring, wherein the inner side of the elastic petals is a conical surface or an inclined surface.

[0046] In one embodiment, Figure 3 、 6 As shown, the housing 1 has an outer ring body 11 and an inner ring body 12 that are spaced apart. The outer ring body 11 is provided with an annular groove opening toward the inner ring body 12 , and the elastic body 4 is located in the annular groove.

[0047] Such an arrangement can well constrain the axial position of the elastic body 4, prevent the elastic body 4 from moving along with the screw sleeve 2, and facilitate stable operation.

[0048] In one embodiment, Figure 3 、 6 As shown, the outer wall of the inner ring body 12 is provided with an O-ring groove, and an O-ring 6 is arranged in the O-ring groove.

[0049] Such an arrangement can ensure a sealed connection between the inner ring body 12 and the connected body.

[0050] In one embodiment, Figure 1 、 3 As shown in Figures 4 and 6, the connector joint that is easy to lock and unlock also includes an insulator 7 and a pin 8. The insulator 7 and the pin 8 are respectively installed in the housing 1, and the insulator 7 is separated between the pin 8 and the housing 1.

[0051] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
