[0002] In existing cups, the cup body and the cup lid are usually arranged to be threadedly connected; when the cup lid of such a structure needs to be opened, the user grasps the cup body with one hand and holds the cup lid tightly with the other hand, and rotates the cup lid relative to the cup body for several circles to separate the cup body and the cup lid; the lid opening action is not convenient enough.

[0003] Therefore, non-threaded cup lids have also appeared on the market, with reference to application number 201510474971.4, and the name is an invention patent for a propped-open container sealing plug. The container plug structure of this patent requires pressing the unlocking pin blocks on both sides inward when unlocking, and the container plug structure of this patent requires driving the push-pull part relatively upward when locking so that the columnar inner plug slides upward relative to the annular outer plug until the locking pin block engages with the locking hole; the operation of unlocking and locking the cup lid is not convenient enough; and the elastic seal is used for sealing, and the structural connection to the cup body is not firm enough. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an easy-to-use threadless cup cover, which solves the problems that the cup cover is not convenient to use and is not stably connected to the cup body.

[0005] The technical solution adopted by the utility model is: a threadless cup cover that is easy to use, comprising an outer shell and a movable plug body, the movable plug body being vertically slidably connected to the outer shell, a first elastic member being commonly abutted between the outer shell and the movable plug body, the first elastic member being used to drive the movable plug body to move downward relative to the outer shell, a locking device being provided on the outer shell and / or the movable plug body; a plurality of locking members are rotatably connected to the movable plug body in the circumferential direction, and a limiting member is protrudingly provided on the inner wall of the outer shell; when the locking device locks the outer shell and the movable plug body, the limiting member abuts and limits the outward deflection angle of the locking member, and the locking member is in a tightened state; after the locking device is unlocked and the movable plug body slides downward relative to the outer shell, the limiting member reduces or releases the limiting effect on the outward deflection angle of the locking member, and the locking member is in a loosened state.

[0006] With the above technical solution, the utility model is used in cooperation with the cup body. A circular protruding portion is provided near the opening of the cup body. When the user brings the cup cover of the utility model close to and closes the opening of the cup body, the movable plug body moves upward relative to the outer shell until the movable plug body and the outer shell are locked by the locking device. Each locking member in the circumferential direction is inwardly contracted under the abutting and limiting action of the limiting member and is buckled with the circular protruding portion. By directly applying pressure, the overall cup cover can be automatically connected to the cup body. After the user operates the locking device to unlock and the movable plug body slides downward relative to the outer shell, the angle that each locking member can deflect outward increases, and each locking member releases the circular protruding portion. At this time, the user can remove the overall cup cover from the cup body. The connection and detachment of the cup cover and the cup body of the utility model require few operations and are very convenient to use. In addition, the connection between the circular protruding portion and the locking member is very stable.

[0007] Further, the limiting member includes a connecting strip and a buckling rod connected to each other. The buckling rod is arranged horizontally. The limiting member includes a first limiting rib for abutting and limiting the buckling rod. The first limiting rib extends vertically. When the locking member is in the released state, the buckling rod is located below the bottom surface of the first limiting rib.

[0008] With the above technical solution, the horizontally extending buckling rod is used in cooperation with the circular protruding portion. When the cup cover is buckled on the cup body, the buckling rod contacts the circular protruding portion at various positions, so that the contact angle range between the locking member and the circular protruding portion in the circumferential direction is larger and the connection is more stable.

[0009] Further, the bottom of the first limiting rib is provided with a first inclined surface, and the first inclined surface is inclined towards the inside and downward.

[0010] With the above technical solution, during the process of buckling the cup cover on the cup body, the buckling rod can more smoothly pass through the bottom of the first limiting rib and deflect inward and contract, making it more convenient to use.

[0011] Further, the connecting strip is connected to the middle of the buckling rod, and the parts of the two ends of the connecting strip exceeding the side of the connecting strip are respectively matched with a corresponding first limiting rib.

[0012] With the above technical solution, the extending length of the buckling rod in the horizontal direction is further increased, the contact angle range between the locking member and the circular protruding portion in the circumferential direction is further increased, and the connection is more stable. The buckling rod is used in cooperation with the two first limiting ribs, so that the forces on both sides of the buckling rod are more uniform.

[0013] Further, the limiting member includes a connecting bar and a fastening rod connected to each other. The fastening rod is horizontally arranged. The limiting member includes a second limiting rib for abutting and limiting the connecting bar. A second inclined surface is provided at the bottom of the second limiting rib, which is inclined towards the inside and downwards; the middle part of the connecting bar is bent and protrudes outwards.

[0014] Through the above technical solution, during the process of the cup cover being buckled on the cup body, the second limiting rib abuts and limits the connecting bar, making the force on the locking member more uniform.

[0015] Further, the movable plug body includes a connecting seat, and a connecting groove with an opening facing outwards is provided on the connecting seat; the limiting member includes a connecting shaft, the fastening rod and the connecting shaft are respectively connected to two ends of the connecting bar, and limiting protrusions are provided on the inner wall of the connecting groove, and the connecting shaft is rotatably connected to the connecting groove and contacts and limits with the limiting protrusions.

[0016] Through the above technical solution, the user presses the connecting shaft towards the connecting groove, the connecting shaft passes through the limiting protrusion and finally snaps into the inside of the connecting groove to realize the rotational connection with the connecting groove, and the assembly of the locking member and the connecting seat is very convenient.

[0017] Further, the movable plug body includes an inner shell fixedly connected to the connecting seat. A through hole is provided on the inner shell. The locking device includes a second elastic member and a positioning pin. The second elastic member is connected to the inner shell and abuts against the positioning pin. One end of the positioning pin extends into the through hole; the outer shell includes a fixing plate, and a locking hole is provided on the fixing plate. When the end of the positioning pin extends into the locking hole, the movable plug body is vertically locked; an avoidance hole is provided on the outer shell, and a button is slidably connected to the avoidance hole. When the button drives the positioning pin to withdraw from the locking hole, the movable plug body is unlocked from the outer shell.

[0018] Through the above technical solution, the user presses the button, the button pushes the positioning pin to withdraw from the locking hole, and then the whole movable plug body automatically slides downwards relative to the outer shell under the action of the first elastic member, so as to switch each locking member to the loosened state, which is very convenient to use.

[0019] Further, a blocking block is provided on the positioning pin. An activity block is vertically slidably connected inside the inner shell. A connecting rod is provided at the bottom of the activity block. An air vent hole is provided on the inner shell or / and the connecting seat. The connecting rod passes through the air vent hole, and a sealing block for blocking the air vent hole is provided at the end of the connecting rod; a third inclined surface is provided on the blocking block, and a fourth inclined surface is correspondingly provided on the activity block, and the third inclined surface is inclined downwards.

[0020] With the above technical solution, when the button is pressed to make the positioning pin withdraw from the locking hole, the fourth inclined surface on the movable block is squeezed by the third inclined surface and slides downward, driving the connecting rod and the sealing block to move downward to open the ventilation hole, avoiding the situation that the cup cover is difficult to open due to the formation of air pressure difference inside and outside the cup body.

A locking device is provided on the housing 1 or / and the movable plug body; A plurality of locking members 3 are rotatably connected to the circumference of the movable plug body, and a limiting member 4 protrudes from the inner wall of the housing 1; When the locking device locks the housing 1 and the movable plug body, the limiting member 4 abuts and limits the angle of outward deflection of the locking member 3, and the locking member 3 is in a tightened state; After the locking device is unlocked and the movable plug body slides downward relative to the housing 1, the limiting member 4 reduces or releases the limiting effect on the outward deflection angle of the locking member 3, and the locking member 3 is in a loosened state.

[0041] The utility model is used in cooperation with a cup body 17. An annular protruding portion 18 is provided near the opening of the cup body 17. When the user brings the cup lid of the utility model close to and covers the opening of the cup body 17, the movable plug body moves upward relative to the housing 1 until the movable plug body and the housing 1 are locked by the locking device. Each locking member 3 in the circumferential direction is inwardly contracted under the abutting and limiting action of the limiting member 4 and is buckled with the annular protruding portion 18. Directly applying pressure can make the overall cup lid automatically connect with the cup body 17; After the user operates the locking device to unlock and the movable plug body slides downward relative to the housing 1, the angle at which each locking member 3 can deflect outward increases, and each locking member 3 releases the annular protruding portion 18. At this time, the user can remove the overall cup lid from the cup body 17.
