SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent mistake and open bowl cover that has locking function.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a cup cover with a locking function comprises an upper cover and a lower cover, wherein a locking piece is arranged between the upper cover and the lower cover and can be switched between a locking state and an unlocking state; the control piece rotates relative to the locking piece to enable the abutting portion to fall in the area of the notch portion or the area of the abutting portion selectively, when the abutting portion falls in the area of the notch portion, the locking piece can move axially to switch between the locking state and the unlocking state, and when the abutting portion falls in the area of the abutting portion, the locking piece is prevented from moving axially to be incapable of switching between the locking state and the unlocking state.
The beneficial effects of the utility model are that through the cooperation between control and the locking piece, can realize the locking of upper cover, improve the safety in utilization of cup, effectively prevent to miss uncapping.

Detailed Description
As shown in fig. 1 to 4, a cup cover with a locking function includes an upper cover 1 and a lower cover 2, and a locking member 3 is disposed between the upper cover 1 and the lower cover 2.
The lower cover 2 is provided with a mounting hole 21, the outer wall of the locking member 3 is provided with a guide groove 31 extending axially, the side wall of the mounting hole 21 is provided with a guide rib 22 corresponding to the guide groove 31, the guide groove 31 is in fit connection with the guide rib 22, the locking member 3 slides back and forth along the length direction (i.e. axial direction) of the guide groove 31 and can be switched between a locking state and an unlocking state, when the locking member 3 is in the locking state, the upper cover 1 and the lower cover 2 can be locked (as shown in fig. 1, 5, 7 and 8), and when the locking member 3 is in the unlocking state, the upper cover 1 can be turned over relative to the lower cover 2 (as shown in fig. 2, 6 and 9).
The locking member 3 is fitted with a control member 4 axially fixed to the lower cover 2 and rotatable in the circumferential direction about the central axis of the locking member 3.
Specifically, the control member 4 is rotatable about the central axis of the locking member 3 by being fitted over the locking member 3, and referring to fig. 10 and 11, the outer peripheral wall of the second end of the control member 4 is provided with a blocking lip 41, and when the locking member 3 is axially movably mounted in the mounting hole 21, the blocking lip 41 of the control member 4 is axially fixed to the lower cover 2 by abutting against the end of the mounting hole 21.
The first end of the control piece 4 is provided with a resisting part 42 and a notch part 43, and the locking piece 3 is provided with a resisting part 32; the control member 4 rotates relative to the locking member 3 to selectively enable the abutting portion 32 to fall in the area of the notch portion 43 or the area of the abutting portion 42, when the abutting portion 32 falls in the area of the notch portion 43, the locking member 3 can move axially to switch between the locking state and the unlocking state, and when the abutting portion 32 falls in the area of the abutting portion 42, the locking member 3 is prevented from moving axially to switch between the locking state and the unlocking state. Specifically, the control member 4 is cylindrical, and the abutting portion 42 and the notch portion 43 are protruded inward from the inner wall of the control member 4 and extend circumferentially around the central axis of the control member 4 as a rotation axis.
Referring to fig. 12 and 13, a shaft portion 33 is disposed at a first end of the locking member 3, the control member 4 is sleeved on the shaft portion 33, and the abutting portion 32 is convexly disposed on an outer wall of the shaft portion 33.
The upper cover 1 is provided with a locking plate 11, and the locking plate 11 is provided with a locking plate hole 12; a locking portion 34 is provided on the second end of the locking member 3, and the locking portion 34 falls into or leaves the lock plate hole 12 by the axial movement of the locking member 3 to provide the locking state and the unlocking state of the locking member 3.
The side wall of the mounting hole 21 close to the upper cover 1 is provided with a butt joint through hole 23, and the locking part 34 is a locking bulge formed on the side wall of the butt joint through hole 23; when the upper cover 1 can be covered on the lower cover 2, the locking plate 11 is inserted into the butt through hole 23 to make the locking plate hole 12 correspond to the locking protrusion.
A return spring 5 is provided between the locking member 3 and the control member 4, and the locking protrusion is kept in a state of falling into the locking piece hole 12 by the return spring 5, and the return spring 5 is compressed by pressing a button 6 described below, and the locking protrusion is separated from the locking piece hole 12. More specifically, the locking member 3 is connected with the button 6, the button 6 includes a pressing portion 61 and a clamping portion 62, the return spring 5 is sleeved on the shaft portion 33, after the clamping portion 62 is in butt joint with the end portion of the shaft portion 33, one end of the return spring 5 abuts against the pressing portion 61, and the other end abuts against the abutting portion 42.
The control member 4 is further provided with a toggle part 44 for facilitating the rotation of the toggle control member.
The periphery wall of the control piece 4 is further provided with a limiting part 45, the limiting part 45 forms two opposite limiting surfaces, the control piece 4 is sleeved on the locking piece 3 and then is installed in the installation hole 21, the guide rib 22 just falls in the area of the limiting part 45, and the rotating angle of the control piece 4 is limited between the two opposite limiting surfaces formed by the limiting part 45.
The limiting groove 24 has been seted up on the lateral wall of mounting hole 21, the lateral wall of locking piece 3 is provided with the spacing rib 35 that can radial inside elastic deformation, and the tip of spacing rib 35 is provided with convex rib 36, and locking piece 3 inserts the mounting hole 21 in-process, and spacing rib 35 restores to the original state after radial inside elastic deformation earlier and makes convex rib 36 card prevent that locking piece 3 from leaving mounting hole 21 in limiting groove 24.
