[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Please refer to Figures 1-6 In the embodiments of the present application, a rotating lock cup cover includes a cover 1 and a switch 2. The cover 1 is composed of an upper cover 11 and a lower cover 12. One side of the upper cover 11 and the lower cover 12 is a hinged side, and the other side is an opening and closing side. The opening and closing side of the upper cover 11 and / or the lower cover 12 is provided with a mounting groove 13. The switch 2 located in the mounting groove 13 is clamped into the corresponding matching part of the lower cover 12 or the upper cover 11 through the horizontal hinging action of the hinge shaft, and is used for locking the opening and closing side in the closed state. The rotating lock cup cover further includes a limiting piece 3, which penetrates the switch 2. With the hinge shaft as a boundary, one end of the switch 2 for locking the opening and closing side is a proximal end, and the other end is a distal end. The contact area between the bottom working end of the limiting piece 3 and the groove bottom of the mounting groove 13 is located at least in the upper locking area between the distal end and the hinge shaft. At this time, the limiting piece 3 limits the horizontal hinging unlocking action of the switch 2, realizes the locking of the switch 2, and the limiting piece 3 can be away from the upper locking area of the groove bottom of the mounting groove 13 through rotating action or swinging action or telescopic action, thereby unlocking the switch 2, so that the switch 2 can complete the horizontal hinging unlocking action, realizes the unlocking of the opening and closing side of the cover 1, and opens the cover 1. The cooperation of the limiting piece 3 and the switch 2 makes the locking effect of the cover 1 better and more secure.

[0029] The limiting piece 3 is a rotating limiting structure, including a rotating column 32 which is perpendicular to the axis of the hinge shaft and co-planar, the rotating column 32 is rotatably fitted on the switch 2 through a guide groove, a guide hole or a guide edge, and rotates according to the guide direction provided by the guide groove, the guide hole or the guide edge, and limits the rotation size of the rotating column 32; the eccentric outer convex limiting block 33 at the inner end of the rotating column 32, the limiting block 33 constitutes the bottom working end of the limiting piece 3, the arc length of the limiting block 33 is less than or equal to half of the arc length of the rotating column 32, so that the end surface of the rotating column 32 without the limiting block 33 is between the groove bottoms of the mounting groove 13, and there is a gap, therefore at least half of the cross section of the rotating column 32 is in a suspended state and does not contact the mounting groove 13, the eccentric limiting block 33 makes the limiting piece 3 have a space to rotate along the axis of the hinge shaft to ensure that the switch 2 can complete the horizontal hinge unlocking action, complete the separation of the opening and closing sides of the upper cover 11 and the lower cover 12, and open the cover body 1; through the rotation of the limiting piece 3, the limiting block 33 switches between the far end to the hinge shaft area, i.e. the locking area, and the near end to the hinge shaft area, i.e. the unlocking area, thereby realizing the switching of the switch state.

[0030] The rotating column 32 is provided with at least two through holes 34 of the same height, and the hinge shaft of the switch 2 penetrates the through holes 34 to provide a space for the rotation of the limiting piece 3, the through holes 34 simultaneously constitute guide holes to provide a guide direction for the movement of the limiting piece 3 and limit the rotation distance of the limiting piece 3, thereby avoiding excessive rotation of the limiting piece 3, excessive friction between the contact surface of the limiting piece 3 and the switch 2, and affecting the connection effect and locking effect.

[0031] The limiting piece 3 further includes a handle 31 coaxially arranged at the outer end of the rotating column 32, the diameter of the handle 31 is greater than that of the rotating column 32, the handle 31 protrudes from the outer surface of the switch 2, and a recess is formed at the end of the handle 31 away from the switch 2, so that the middle part of the end surface of the handle 31 forms a protrusion, which is convenient for a user to place a finger in the recess to hold the protrusion part and exert force to drive the limiting piece 3 to rotate.

[0032] The switch 2 is provided with a mounting hole 21, and the limiting piece 3 is connected with the switch 2 through the mounting hole 21, a first positioning groove 22 and a second positioning groove 23 are formed on the end surface of the mounting hole 21 away from the cover body 1, a positioning block 35 is arranged on the end surface of the handle 31 towards the rotating column 32, the positioning block 35 is clamped with the first positioning groove 22 or the second positioning groove 23, and the first positioning groove 22 and the second positioning groove 23 correspond to the contact of the limiting block 33 with the locking area on the groove bottom of the mounting groove 13, respectively Case and limit block 33 with anThe unlocking area of the groove bottom of the groove 13 contacts, that is, the unlocking state and the locking state of the switch 2 correspond, the clamping of the limiting piece 3 and the switch 2 is realized by the clamping of the positioning block 35 and the first positioning groove 22 or the second positioning groove 23, and the unlocking state or the locking state of the switch 2 is better maintained.

[0033] The working principle of the utility model is: when the utility model is used, the rotation of the limiting piece 3 is realized by holding the handle 31, the contact position of the limiting block 33 at the bottom of the limiting piece 3 with the mounting groove 13 is changed, and the contact position of the limiting block 33 with the mounting groove 13 is changed.

[0034] When the contact position of the limiting block 33 with the mounting groove 13 is located in the unlocking area between the proximal end of the switch 2 and the hinged shaft, the switch 2 is in the unlocking state, at this time, the distal end part of the switch 2 is pressed, the switch 2 rotates around the hinged shaft, the upper hook 24 arranged at the proximal end of the switch 2 gradually separates from the lower hook 14 arranged on the upper cover 11, the lower hook 14 is located in the mounting groove 13, the clamping of the upper cover 11 and the lower cover 12 on the opening side is realized by the contact of the upper hook 24 and the lower hook 14, at this time, the limiting block 33 also rotates with the switch 2 and separates from the groove bottom of the mounting groove 13, when the distal end of the switch 2 contacts the bottom of the mounting groove 13, the switch 2 stops rotating, at this time, the upper hook 24 and the lower hook 14 completely separate, and the unlocking of the opening side of the upper cover 11 and the lower cover 12 is completed.

[0035] When the contact position of the limiting block 33 with the mounting groove 13 is located in the locking area between the distal end of the switch 2 and the hinged shaft, the switch 2 is in the locking state, at this time, the distal end part of the switch 2 is pressed, at this time, due to the limitation of the limiting block 33, the switch 2 cannot rotate around the hinged shaft or the distal end of the switch 2 cannot rotate to contact the bottom of the mounting groove 13, at this time, the upper hook 24 and the lower hook 14 cannot separate, and the clamping state of the opening side of the upper cover 11 and the lower cover 12 cannot be released, and the cover body 1 is locked (it should be noted that the upper cover 11, the lower cover 12, the upper hook 24, the lower hook 14, the mounting groove 13 and the hinged shaft are all common structures in the prior art, and the present scheme does not improve them, and in order to better reflect the cooperation relationship between the structures, the hinged shaft is omitted in the drawings of the specification, but it does not affect the understanding of the setting position, therefore, it will not be described again).
