Description

Technical Field

[0001] The utility model relates to the field of water cups, in particular to a knob-type flip cover. Background Art

[0002] Most of the current water cups have lids that are tightened by threads. Users need to hold the lid tightly and rotate it several times on the cup body before opening it. Users need to use a lot of force when rotating the lid. However, this type of lid is prone to leaking when not screwed in place, or being screwed too tightly, making it difficult to open the cup, making the cup inconvenient to use.

[0003] Therefore, there is a need on the market for a cup lid with a relatively small rotation range, which allows users to open the cup faster and with less effort, making it easier for users to drink water in various usage scenarios. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a knob-type flip cover, which solves the problem that the traditional threaded cup cover is not convenient to open.

[0005] The technical solution adopted by the utility model is: a knob-type flip cover, comprising a flip cover and a base rotatably connected to each other, the base being provided with a drinking water unit, the flip cover being provided with a mounting hole, the mounting hole being rotatably connected to a rotating member, the rotating member being fixedly connected to a movable member, and the movable member being rotatably connected to the flip cover; a follower is also provided, the follower comprising a claw portion and a driven block, the flip cover being provided with a avoidance opening for the claw portion to pass through, the drinking water unit being further provided with a clamping portion, the claw portion and the clamping portion being clamped or disengaged, the movable member comprising a pushing portion, the pushing portion abutting against the driven block, a baffle being provided on the flip cover, the baffle and the driven block jointly abutting against a first elastic member, and points A and B being provided on the edges of the pushing portion in contact with the driven block, and a distance from a rotation center of the rotating member on a transition path from point A to point B gradually becomes smaller.

[0006] Through the above technical solution, the user drives the rotating part on the flip cover to rotate, thereby driving the movable part to rotate, so that the contact position of the driven block with the pushing part transitions from point A to point B. During this process, the movable part gradually slides toward the direction close to the rotation center of the rotating part until the claw part and the clamping part are disengaged; the user only needs to rotate the rotating part at a single small angle to realize the opening action of the cup lid, which is very convenient to use.

[0007] Furthermore, a point C is provided on the edge of the push portion that contacts the driven block, and the distance from the rotation center of the rotating member on the transition path from point A to point C gradually decreases, and points B and C are located on both sides of point A respectively.

[0008] Through the above technical solution, the user can drive the rotating part on the flip cover to rotate in the opposite direction, thereby driving the movable part to rotate in the opposite direction, so that the contact position of the driven block with the pushing part transitions from point A to point C. During this process, the movable part gradually slides toward the direction close to the rotation center of the rotating part until the claw part and the clamping part are disengaged; the user can quickly open the cup lid regardless of forward or reverse rotation, which greatly expands the usage scenarios of the cup lid.

[0009] Furthermore, a force-bearing inclined surface is provided on the side of the driven block facing the pushing portion. There are two force-bearing inclined surfaces on the driven block, which are symmetrically arranged with each other, and the two force-bearing inclined surfaces are arranged at an obtuse angle to each other.

[0010] Through the above technical solution, the arrangement of the force-bearing inclined surface greatly reduces the driving force required by the push portion to push the driven block, which saves the user more effort when turning the cup cover and is extremely convenient to use.

[0011] Furthermore, the movable part further includes a connecting portion, the connecting portion and the pushing portion are integrally formed, and the driven block is always located in the pushing portion.

[0012] Through the above technical solution, the driven block is always located in the push part, so that the connection between the driven block and the push part is very stable, avoiding deformation or even breakage of the push part, and greatly extending the service life of the movable part; at the same time, the movement path of the driven block is very stable, avoiding the driven block from leaving the predetermined position alone.

[0013] Furthermore, a positioning groove is provided on the rotating part, and a mounting column is provided on the connecting part. The mounting column is clamped with the positioning groove. A limiting protrusion is provided in the positioning groove, and a limiting notch is correspondingly provided on the mounting column. The limiting protrusion is clamped with the limiting notch.

[0014] Through the above technical solution, the mounting column and the positioning groove are clamped together, making the assembly of the rotating part and the movable part very convenient; the limiting protrusion and the limiting notch are clamped together, making the connection between the rotating part and the movable part tighter and the overall structure more solid.

[0015] Furthermore, an elastic device for connecting the movable part is provided on the flip cover, and extension parts are provided on both sides of the connecting part. The elastic device includes a second elastic part and a connecting column. The connecting column is provided on the flip cover, the second elastic part is connected to the connecting column, and the two ends of the second elastic part are respectively connected to the two extension parts.

[0016] Through the above technical solution, the two ends of the second elastic member are respectively connected to the two extension parts so that the movable member can be reset in time after rotation, which is more convenient to use.

[0017] Furthermore, a limiting groove is provided at the bottom of the connecting portion, and a limiting block is correspondingly provided on the flip cover, and the limiting block is rotatably connected to the limiting groove.

[0018] Through the above technical solution, the rotational connection between the limiting block and the limiting groove makes it very convenient to install the movable part on the flip cover, which is beneficial to the production and assembly in the factory.

[0019] Furthermore, the first elastic member is a spring, a positioning notch is provided on the driven block, a positioning column is provided in the positioning notch, one end of the spring extends into the positioning notch and is sleeved on the positioning column, and the other end of the spring abuts against the baffle.

[0020] Through the above technical solution, the spring structure is simple and the cost is low, which can greatly reduce the production cost; the setting of the positioning notch and the positioning column makes the installation of the spring more convenient, the overall structure is more compact, and the volume of the cup cover is greatly reduced.

[0021] Furthermore, the drinking water unit is a drinking water port, and the clamping portion is located on the outer side wall of the drinking water port.

[0022] Through the above technical solution, the arrangement of the water spout enables the user to drink water very conveniently, and is very easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

The movable member 5 includes a push portion 502, which abuts against a driven block 602. The flip cover 1 is provided with a baffle 8, which abuts against a first elastic member 9. Points A 10 and B 11 are provided on the edge of the push portion 502 that contacts the driven block 602. The distance from the rotation center of the rotating member 4 gradually decreases along the transition path from point A 10 to point B 11. When a user rotates the rotating member 4 on the flip cover 1, the movable member 5 rotates, causing the contact point on the driven block 602 with the push portion 502 to transition from point A 10 to point B 11. During this process, the movable member 5 gradually slides toward the rotation center of the rotating member 4 until the claw portion 601 disengages from the latching portion 26. The user only needs to rotate the rotating member 4 by a single, small angle to open the cup lid, making it very convenient to use.

[0043] See Figure 3 、 4As shown in Figures 5, 11, and 12, a point C 12 is further provided on the edge of the push portion 502 that contacts the driven block 602. The distance from the rotation center of the rotating member 4 gradually decreases along the transition path from point A 10 to point C 12, with points B 11 and C 12 located on either side of point A 10. The user can drive the rotating member 4 on the flip cover 1 to rotate in the opposite direction, thereby driving the movable member 5 to rotate in the opposite direction, causing the contact point on the driven block 602 with the push portion 502 to transition from point A 10 to point C 12. During this process, the movable member 5 gradually slides toward the rotation center of the rotating member 4 until the claw portion 601 disengages from the engaging portion 26. The user can quickly open the cup lid regardless of whether the cup lid is rotated forward or reverse, greatly expanding the usage scenarios of the cup lid.

[0044] See Figure 9 As shown, a force-bearing inclined surface 13 is provided on the side of the follower block 602 facing the push portion 502. There are two force-bearing inclined surfaces 13 on the follower block 602, which are symmetrically arranged and set at an obtuse angle to each other. The provision of the force-bearing inclined surfaces 13 significantly reduces the driving force required by the push portion 502 to push the follower block 602, saving the user effort when turning the cup lid, making it extremely convenient to use.
