[0030] The following is a detailed description with reference to the accompanying drawings and embodiments:

[0031] Please also read Figures 1 to 5The embodiment of the present application provides a plug assembly, which includes a plug pin 10 and a sleeve 20. A chamber 201 is formed inside the sleeve 20. A socket 202 is provided on one side of the sleeve 20. The plug pin 10 can penetrate the socket 202 along the axial direction and extend into the chamber 201. The sleeve 20 is also provided with a notch 203 on the outer periphery of the socket 202. The notch 203 is communicated with the socket 202. The sleeve 20 is also provided with a stopper 21 in the chamber 201. The plug pin 10 includes a main body 11, a pulling part 12 and a locking part 13. The shape of the inner circumferential wall of the chamber 201 is adapted to the cross-sectional shape of the main body 11 along the axial direction. The pulling part 12 and the locking part 13 are respectively arranged on opposite sides of the main body 11 along the axial direction. When the plug pin 10 and the sleeve 20 are in a connected state, The locking portion 13 is placed at the bottom of the chamber 201, the portion of the main body 11 adjacent to the locking portion 13 is placed in the chamber 201, and the pulling portion 12 is placed outside the chamber 201. The outer periphery of the pulling portion 12 radially protrudes relative to the outer periphery of the main body 11. After the latch 10 passes through the socket 202 and extends into the chamber 201, the user aligns the pulling portion 12 with the recess 203 by twisting the main body 11 in the circumferential direction, so that part of the pulling portion 12 is stuck in the recess 203, and the stopper 21 limits the axial movement of the locking portion 13, so that the latch 10 can be firmly installed in the sleeve 20. The user can pull the pulling portion 12 in the axial direction to disengage the pulling portion 12 from the recess 203, so as to facilitate the disassembly between the latch 10 and the sleeve 20.

[0032] Specifically, by arranging the latch 10 and the sleeve 20 to cooperate with each other, when the latch 10 is installed in the sleeve 20, the user only needs to insert the latch 10 through the socket 202 into the bottom of the chamber 201, and twist the main body 11 in one direction by a certain angle so that part of the pulling portion 12 is stuck in the recess 203, thereby completing the assembly between the latch 10 and the sleeve 20.

[0033] Specifically, when removing the latch 10 from the sleeve 20, the user only needs to pull the pulling portion 12 axially to disengage from the notch 203, and twist the main body 11 in another direction by the same angle, so that the latch 10 can be pulled out from the bottom of the chamber 201, thereby completing the disassembly between the latch 10 and the sleeve 20.

[0034] In application, the installation and disassembly operations between the latch 10 and the sleeve 20 are simpler, the alignment between the pulling portion 12 of the latch 10 and the notch 203 of the sleeve 20 is more accurate, the assembly efficiency of the plug-in assembly is higher, and the use is more convenient. The notch 203 can limit the circumferential rotation of the pulling portion 12, and the stopper 21 can limit the axial movement of the locking portion 13, so that the connection between the latch 10 and the sleeve 20 is more stable.

[0035] In one embodiment, please refer to Figures 1 to 5The main body 11 is provided with a first through groove 101, and openings of the first through groove 101 are respectively formed on opposite sides of the main body 11 in the radial direction. The pulling part 12 includes a mounting seat 121, an elastic member 122 and a sliding member. The mounting seat 121 and the elastic member 122 are both placed in the first through groove 101, the elastic member 122 is connected to one side of the mounting seat 121 in the axial direction, the sliding member is connected to one side of the mounting seat 121 in the radial direction, and the side of the sliding member away from the mounting seat 121 extends out from the opening of the first through groove 101, and the sliding member is used to engage with the notch 203.

[0036] In application, the user can pull the sliding member along the axial direction of the main body 11. After the sliding member leaves the initial position, it can disengage from the recess 203 and drive the mounting seat 121 to move so that the elastic member 122 is squeezed and deformed. After the pulling effect applied by the user to the sliding member disappears, the squeezing deformation of the elastic member 122 is restored, thereby driving the mounting seat 121 to drive the pulling member to move to the initial position.

[0037] In one embodiment, please refer to Figures 1 to 5 There are two notches 203 and two sliding members, and the two notches 203 correspond to the two sliding members one by one. The two sliding members are respectively arranged at the two openings of the first through groove 101, and the two sliding members are symmetrically arranged to make it easier for users to pull out the sliding members.

[0038] In one embodiment, please refer to Figures 1 to 5 The mounting seat 121 is provided with a first groove 102, and the elastic member 122 is installed in the first groove 102. The elastic member 122 can be a spring. Along the axial direction of the main body 11, one end of the elastic member 122 is connected to the bottom wall of the first groove 102, and the other side is connected to the top wall of the first through groove 101, so that the elastic member 122 can be deformed along the axial direction and the radial displacement of the elastic member 122 can be limited, thereby making the sliding member move more smoothly along the axial direction.

[0039] In one embodiment, please refer to Figures 1 to 5 The sliding member includes a paddle 123 and a pin 124 . The paddle 123 defines a first through hole 103 . The mounting seat 121 defines a second groove 104 . A portion of the pin 124 passes through the first through hole 103 and is installed in the second groove 104 . The shape of another portion of the pin 124 matches the shape of the recess 203 .

[0040] In application, the pin 124 may be threadedly assembled with the inner wall of the second groove 104 . It is understandable that the pin 124 may also be snap-fitted with the inner wall of the second groove 104 .

[0041] In one embodiment, please refer to Figures 1 to 5A plurality of ridges 125 are provided on the side of the paddle 123 facing away from the mounting seat 121, which are used to enhance the friction coefficient on the surface of the paddle 123. A third groove 105 is provided on the side of the paddle 123 facing the mounting seat 121. The mounting seat 121 is provided with a flange 126 that matches the shape of the third groove 105. By inserting the flange 126 into the third groove 105, the connection stability between the sliding member and the mounting seat 121 can be enhanced, making the pulling portion 12 more durable.

[0042] In one embodiment, please refer to Figures 1 to 5 The main body 11 is also provided with a slide groove 106 at the opening of the first through groove 101, and the paddle 123 is placed in the slide groove 106. The outer contour shape of the paddle 123 is adapted to the inner wall shape of the slide groove 106. The slide groove 106 is used to limit the movable range of the paddle 123 and reduce the deviation of the paddle 123 during the axial movement, so that the user's pulling operation on the pulling part 12 is smoother.

[0043] In one embodiment, please refer to Figures 1 to 5 The stopping member 21 is provided with a second through slot 204, and openings of the second through slot 204 are respectively formed on opposite sides of the stopping member 21 along the axial direction. The locking portion 13 can extend to the second through slot 204 so that the stopping member 21 is sleeved on the outer periphery of the locking portion 13, and the locking portion 13 can rotate in the second through slot 204 as the main body 11 rotates.

[0044] In one embodiment, please refer to Figures 1 to 5 The stopping member 21 is provided with a first boss 211 on the inner circumferential wall of the second through groove 204. The main body 11 is a cylindrical structure. The main body 11 and the locking part 13 are integrally made of alloy or plastic material. An annular groove 107 is formed inwardly at the connection between the main body 11 and the locking part 13. The annular groove 107 is for the first boss 211 to be placed, so that the first boss 211 can be snap-fitted and installed in the annular groove 107.

[0045] In application, along the axial direction of the main body 11 , the distance between the adjacent two side walls of the annular groove 107 is the same as the height of the first boss 211 .

[0046] In one embodiment, please refer to Figures 1 to 5 The first boss 211 extends from a side opening of the second through groove 204 adjacent to the main body 11 toward the middle of the second through groove 204. There are two first bosses 211, which are symmetrically arranged on the inner circumferential wall of the second through groove 204. The locking portion 13 is provided with second bosses 131 on opposite sides along the radial direction so that the outer contour shape of the locking portion 13 is adapted to the shape of the side opening of the second through groove 204.

[0047] In application, along the axial direction of the main body 11, the sum of the height of the second boss 131 and the height of the first boss 211 is not greater than the height of the inner circumferential wall of the second through groove 204. When the pin 10 is fixed to the sleeve 20, along the radial direction of the main body 11, the opposite sides of the first boss 211 are respectively in contact with the main body 11 and the second boss 131.

[0048] In application, the two first bosses 211 , the two recesses 203 , the two second bosses 131 and the two pins 124 are arranged in the same plane.

[0049] Specifically, when the latch 10 is installed on the sleeve 20, each pin 124 is first placed between the two recesses 203 at the middle position along the circumference of the main body 11; then the locking portion 13 is axially extended into the socket 202 until the pin 124 is placed at the end of the slide groove 106 away from the socket 202. At this time, the elastic member 122 is compressed and deformed, and the second boss 131 is located on the side of the first boss 211 away from the socket 202, and the first boss 211 is located in the annular groove 107; finally, the main body 11 is rotated circumferentially until the pin 124 is located above the recess 203. At this time, the compression deformation of the elastic member 122 is restored to drive the pin 124 to move to the end of the slide groove 106 close to the socket 202 and placed in the recess 203, and the opposite sides of the first boss 211 are respectively pressed against the main body 11 and the second boss 131.

[0050] Specifically, when the latch 10 is removed from the sleeve 20, the paddle 123 is first pulled axially until the pin 124 is disengaged from the notch 203 and placed at the end of the slide groove 106 away from the socket 202; then the main body 11 is rotated circumferentially until each pin 124 is placed in the middle position between the two notches 203 along the circumference of the main body 11, at which time the abutment between the first boss 211 and the second boss 131 disappears; finally, the locking portion 13 is pulled out of the socket 202 axially.

[0051] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
