Description
Technical Field
[0001] This application relates to the technical field of plug connection structures, and in particular to a waterproof plug connection structure with a locking reminder function. Background Art
[0002] A waterproof plug connection structure generally consists of a male plug, a female plug, and a nut, and has certain requirements for the waterproof level; due to the requirements for the waterproof level and sealing performance, whether the waterproof plug connection structure is locked during connection has an obvious impact on the overall use effect of the structure.
[0003] In the prior art, the locking of the waterproof plug during connection completely depends on the manual experience of the operator. There are differences among different operators during operation, resulting in the locking effect not being guaranteed, which may affect the subsequent normal use of the corresponding equipment. Utility Model Content
[0004] In order to improve the consistency of different operators during the locking operation, thereby ensuring the locking effect of the connection structure, this application provides a waterproof plug connection structure with a locking reminder function.
[0005] This application provides a waterproof plug connection structure with a locking reminder function, and adopts the following technical solutions:
[0006] A waterproof plug connection structure with a locking reminder function includes a male plug and a female plug. One end of the female plug is inserted into the male plug. An external thread is provided on the circumferential outer wall of the male plug near the female plug. A nut for threaded connection with the external thread is sleeved on the circumferential periphery of the female plug. A waterproof gasket for waterproofing is sleeved on the female plug. A locking reminder assembly is jointly provided on the female plug and the nut, and the locking reminder assembly is used to remind the locking degree of the connection structure. A locking indication assembly is jointly provided on the nut and the male plug, and the locking indication assembly is used to indirectly display the locking degree of the connection structure.
[0007] By adopting the above technical solutions, the waterproof gasket helps to seal and waterproof the connection structure. The locking reminder assembly helps to remind the locking degree of the connection structure when the operator performs the locking operation. The locking indication assembly helps to indirectly display the locking degree of the connection structure to the operator. The combined action of the locking reminder assembly and the locking indication assembly helps to improve the consistency of different operators during the locking operation, thereby helping to ensure the locking effect of the connection structure.
[0008] In a specific feasible implementation, the locking reminder component includes a spiral protrusion and an abutting ring. The spiral protrusion is provided on the inner wall of the nut at the end away from the male plug, the abutting ring is provided on the circumference of the female plug, and a biting surface for biting interference with the spiral protrusion is provided on the side of the abutting ring facing away from the male plug.
[0009] By adopting the above technical solution, when the operator performs a locking operation on the connection structure, when the nut rotates, it will drive the spiral protrusion to move synchronously towards the abutting ring; when the nut rotates to a set position, the spiral protrusion will bite and interfere with the corresponding biting surface on the abutting ring, so that the operator's operating feel changes, which helps to remind the operator that the connection structure is about to be locked. At this time, when the operator rotates the nut by a set angle, the connection structure can be locked in place, which helps to improve the consistency of different operators during the locking operation and helps to ensure the locking effect of the connection structure.
[0010] In a specific feasible implementation, a plurality of spiral protrusions are provided, and the plurality of spiral protrusions are arranged in a circumferential inner wall of the nut in an annular array. A plurality of biting surfaces are provided and the number is the same as that of the spiral protrusions, and the plurality of biting surfaces are arranged in an annular array on the abutting ring.
[0011] By adopting the above technical solution, the arrangement of the plurality of spiral protrusions and the biting surfaces helps to enhance the change in the operating feel when the spiral protrusions and the biting surfaces bite and interfere, which helps to improve the operator's perception of the change in the operating feel, and further improves the reminder effect on the operator.
[0012] In a specific feasible implementation, the locking indication component includes an indicating arrow, a first limit line and a second limit line. The indicating arrow is provided on the nut and points to the male plug, and the first limit line and the second limit line are spaced apart on the circumferential outer wall of the male plug.
[0013] By adopting the above technical solution, when the nut rotates, the indicating arrow rotates synchronously. Using the position where the indicating arrow points between the first limit line and the second limit line helps to indirectly show the locking degree of the connection structure to the operator, which helps to facilitate the operator to observe whether the connection structure is locked in place.
[0014] In a specific feasible implementation, a first alignment plane is provided on the circumferential outer wall of the nut, the indicating arrow is provided on the first alignment plane, a second alignment plane is provided on the circumferential outer wall of the male plug, and the first limit line and the second limit line are spaced apart on the second alignment plane.
[0015] By adopting the above technical solution, when the connection structure is locked in place, the first alignment plane and the second alignment plane will align with each other, which helps to further facilitate the operator to observe whether the connection structure is locked in place.
[0016] In a specific feasible implementation, anti-slip protrusions are provided on both the male plug and the nut.
[0017] By adopting the above technical solution, the anti-slip protrusions help to increase the friction between the operator and the outer wall of the nut when turning the nut, which helps to play an anti-slip role, and further helps to improve the convenience of the operator during the locking operation.
[0018] In a specific feasible implementation, a guiding groove is provided on the circumferential outer wall of the female plug, the length direction of the guiding groove is arranged along the axial direction of the female plug, and a guiding strip for inserting into the guiding groove is provided on the inner wall of the male plug.
[0019] By adopting the above technical solution, when one end of the female plug is inserted into the male plug, the insertion of the guiding strip into the guiding groove helps to guide and limit the insertion position of the female plug, which helps to improve the accuracy of the position where the female plug is inserted into the male plug. When the operator performs the locking operation, the guiding strip inserted into the guiding groove helps to prevent relative rotation between the male plug and the female plug, which helps to facilitate the operator to perform the locking operation.
[0020] In summary, the present application includes at least one of the following beneficial technical effects:
[0021] 1. Through the setting of the locking reminder component and the locking indication component in the present application, the locking reminder component helps to remind the locking degree of the connection structure, and the locking indication component helps to indirectly show the locking degree of the connection structure to the operator, which helps to facilitate the operator to observe whether the connection structure is locked in place. The combined action of the locking reminder component and the locking indication component helps to improve the consistency of different operators during the locking operation, and further helps to ensure the locking effect of the connection structure.

Detailed implementation manners
[0026] The present application will be further described in detail below with reference to the accompanying drawings.
[0027] An embodiment of the present application discloses a waterproof plug connection structure with a locking reminder function. Referring to Figure 1 and Figure 2 , it includes a male plug 1 and a female plug 2. One end of the female plug 2 is correspondingly inserted into the inside of the male plug 1. A guiding groove 11 is axially formed on the circumferential outer wall of the end of the female plug 2 inserted into the male plug 1 along its own axis, and a guiding strip 12 is integrally formed on the inner wall of the male plug 1 along its own axis.
[0028] Referring to Figure 1 and Figure 2 , when the operator inserts one end of the female plug 2 into the inside of the male plug 1, the guiding strip 12 is correspondingly inserted into the guiding groove 11, which helps to guide and limit the position of the female plug 2 inserted into the inside of the male plug 1, and thus helps to improve the accuracy of the insertion position of the female plug 2. At the same time, the insertion of the guiding strip 12 into the guiding groove 11 also helps to prevent relative rotation between the male plug 1 and the female plug 2, and thus helps to improve the stability of the connection between the male plug 1 and the female plug 2.
[0029] Referring to Figure 1 and Figure 2 , an external thread 3 is integrally formed on the circumferential outer wall of the male plug 1 near one end of the female plug 2. A nut 4 is movably sleeved on the circumferential periphery of the female plug 2, and the nut 4 is threadedly connected to the external thread 3. A waterproof gasket 5 is fixedly sleeved on the circumferential outer wall of the female plug 2, and the waterproof gasket 5 is located inside the nut 4. A plurality of anti-slip protrusions 10 are integrally formed on the circumferential outer walls of the male plug 1 and the nut 4.
[0030] Referring to Figure 1 and Figure 2 , when performing the locking operation on the connection structure, the operator grasps the male plug 1 and the nut 4, and at the same time rotates the nut 4, so that the nut 4 moves towards the male plug 1 under the guiding action of the external thread 3, thereby locking the connection between the male plug 1 and the female plug 2. The anti-slip protrusions 10 help to play an anti-slip role when the operator rotates the nut 4, and thus help to improve the convenience of the operator during the locking operation.
[0031] Referring to Figure 2 andFigure 3 A locking reminder assembly 6 is jointly provided on the male plug 2 and the nut 4. The locking reminder assembly 6 includes a spiral protrusion 61 and an abutting ring 62. In this embodiment, there are four spiral protrusions 61, and the four spiral protrusions 61 are fixedly installed on the circumferential inner wall of the nut 4 away from the male plug 1 and are arranged in a circular array. The abutting ring 62 is integrally formed on the circumferential outer wall of the female plug 2, and four engaging curved surfaces 621 arranged in a circular array are integrally formed on the side of the abutting ring 62 facing away from the male plug 1.
[0032] Refer to Figure 1 and Figure 2 When the nut 4 moves, the four spiral protrusions 61 move towards the abutting ring 62 while rotating. When the nut 4 rotates to the set position, the spiral protrusions 61 will engage and interfere with the corresponding engaging curved surfaces 621 on the abutting ring 62, so that the operating feel of the operator changes, which helps to remind the operator that the connection structure is about to be locked. After that, when the operator rotates the nut 4 by 90 degrees, the connection structure is locked in place, which helps to improve the consistency of different operators during the locking operation, thus helping to ensure the locking effect of the connection structure.
[0033] Refer to Figure 1 and Figure 2 A locking indication assembly 7 is jointly provided on the nut 4 and the male plug 1. The locking indication assembly 7 includes an indication arrow 71, a first limit line 72 and a second limit line 73. There is a first alignment plane 8 on the circumferential outer wall of the nut 4, and the indication arrow 71 is fixedly located on the first alignment plane 8 and points to the male plug 1. There is a second alignment plane 9 on the circumferential outer wall of the male plug 1, and the first limit line 72 and the second limit line 73 are fixedly spaced on the second alignment plane 9.
[0034] Refer to Figure 1 and Figure 2 When the operator feels the change in the operating feel and rotates the nut 4 by 90 degrees, the first alignment plane 8 and the second alignment plane 9 are aligned with each other. At the same time, the arrow direction of the indication arrow 71 points to the middle position between the first limit line 72 and the second limit line 73, which helps the operator observe the locking situation of the connection structure; at this time, the waterproof gasket 5 just meets the waterproof requirements of the connection structure.
[0035] The implementation principle of the embodiment of this application is as follows: When the operator inserts one end of the female plug 2 into the male plug 1, the guiding strip 12 is correspondingly inserted into the guiding groove 11, which helps to guide and limit the position of the female plug 2 inserted into the male plug 1, and thus helps to improve the accuracy of the insertion position of the female plug 2. At the same time, the insertion of the guiding strip 12 into the guiding groove 11 also helps to prevent relative rotation between the male plug 1 and the female plug 2, thus helping to improve the stability of the insertion of the male plug 1 and the female plug 2.
[0036] When performing the locking operation on the connection structure, the operator grasps the male plug 1 and the nut 4 and rotates the nut 4 at the same time, so that the nut 4 moves towards the male plug 1 under the guiding action of the external thread 3, thereby locking the connection between the male plug 1 and the female plug 2. The anti-slip protrusion 10 helps to play an anti-slip role when the operator rotates the nut 4, thus helping to improve the convenience of the operator during the locking operation.
[0037] When the nut 4 moves, the four spiral protrusions 61 move towards the abutting ring 62 while rotating. When the nut 4 rotates to the set position, the spiral protrusion 61 will engage and interfere with the engaging surface 621 on the corresponding abutting ring 62, so that the operating feel of the operator changes, which helps to remind the operator that the connection structure is about to be locked. After that, when the operator rotates the nut 4 by 90 degrees, the connection structure is locked in place, which helps to improve the consistency of different operators during the locking operation, thus helping to ensure the locking effect of the connection structure.
[0038] When the operator feels the change in the operating feel and rotates the nut 4 by 90 degrees, the first alignment plane 8 is aligned with the second alignment plane 9, and at the same time, the arrow direction of the indicating arrow 71 points to the middle position between the first limit line 72 and the second limit line 73, which helps the operator to observe the locking status of the connection structure; at this time, the waterproof gasket 5 just meets the waterproof requirements of the connection structure.
[0039] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
