Description

Technical Field

[0001] The utility model relates to the field of cups, and particularly to a straight cup with a rotary knob for opening the lid. Background Art

[0002] For containers, especially water cups, the lids thereof are usually connected to the ports of the cup bodies by threads. When opening or closing such a water cup, the lid needs to be rotated relative to the cup body for several turns to achieve the purpose. The operation is not convenient enough. If the lid is screwed too close, it is not easy to open. If the lid is not screwed tightly, water leakage is likely to occur.

[0003] How to replace the traditional thread structure on the market to realize the connection between the cup body and the lid, and enable the user to quickly open the lid is a technical problem to be solved in the design. Summary of the Utility Model

[0004] To solve the above problems, the utility model provides a straight cup with a rotary knob for opening the lid, which solves the problem that the cup body and the lid connected by the traditional thread cannot be quickly opened.

[0005] The technical solution adopted by the utility model is as follows: a straight cup with a rotary knob for opening the lid, including a cup body and a lid. The cup body includes a cup mouth part, and an annular groove is provided on the cup mouth part. The lid includes a bottom lid and a twist lid which are rotatably connected to each other. An active part is slidably connected in the radial direction of the bottom lid, and an elastic device for applying an elastic force to the active part towards the inner direction of the lid is provided on the bottom lid. The active part includes a hook part and a driven block. A through groove for the hook part to pass through is opened on the bottom lid. A pushing bar is connected inside the twist lid. The driven block is located between the pushing bar and the twist lid. Points a and b are provided on the edge of the pushing bar in contact with the driven block. The distance from the path from point a to point b to the rotation center of the twist lid gradually increases.

[0006] Through the above technical solution, when the user rotates the twist lid relative to the bottom lid, the contact point of the driven block with the pushing bar transitions from point a to point b. During this process, the active part gradually slides in a direction away from the rotation center of the twist lid until the hook part is disengaged from the annular groove. The user can open the lid by rotating the twist lid with a small angle once, and the use is very convenient.

[0007] Furthermore, a point c is also provided on the edge of the pushing bar in contact with the driven block. The distance from the path from point a to point c to the rotation center of the twist lid gradually increases. Points b and c are respectively located on both sides of point a.

[0008] Through the above technical solution, when the user rotates the twist cap in the reverse direction relative to the bottom cover, the contact point on the driven block that contacts the pushing strip transitions from point a to point c. During this process, the movable member gradually slides in a direction away from the center of rotation of the twist cap until the hook portion is disengaged from the annular groove; the user can quickly open the cup lid by rotating the twist cap forward and backward at a small angle, which is very convenient to use.

[0009] Further, a force-receiving inclined surface is provided on one side of the driven block facing the pushing strip. The number of force-receiving inclined surfaces on the driven block is two and they are symmetrically arranged. The two force-receiving inclined surfaces are arranged at an obtuse angle to each other.

[0010] Through the above technical solution, the provision of the force-receiving inclined surface makes it more labor-saving for the pushing strip to push the driven block and more convenient to use.

[0011] Further, both ends of the pushing strip are connected to the twist cap, and the driven block is always located within the range enclosed by the pushing strip and the twist cap.

[0012] Through the above technical solution, the connection relationship between the pushing strip and the twist cap is made more firm, avoiding deformation or even breakage of the pushing strip and having a longer service life; it also makes the working state of the driven block more stable and prevents it from detaching from the predetermined position alone.

[0013] Further, the movable member includes a slider, and a limiting strip is provided on the bottom cover. The limiting strips are arranged in pairs, and the slider is connected between a pair of the limiting strips.

[0014] Through the above technical solution, the structure of the limiting strip is simple, the forces on both sides of the slider are more uniform, and the sliding connection state is very stable.

[0015] Further, the movable member includes a connecting rod, and a positioning block is provided on the connecting rod; the elastic device includes an elastic member and a baffle. The baffle is provided on the bottom cover, and an avoidance notch for the connecting rod to pass through is provided on the baffle. The elastic member abuts between the baffle and the positioning block.

[0016] Through the above technical solution, the structure of the elastic device is simple and easy to manufacture; the provision of the avoidance notch makes the internal structure of the cup lid more compact, which is beneficial to reducing the overall volume of the cup lid.

[0017] Further, a top cover is fixedly connected to the bottom cover, and the bottom cover closes the port of the avoidance notch.

[0018] Through the above technical solution, the situation where the connecting rod disengages from the avoidance notch during use is avoided, making the installation state of the connecting rod more stable. The top cover, the twist cap and the bottom cover form an internal space, reducing the pollution and erosion of the parts installed in this space. Description of the Drawings

Points a 71 and b 72 are provided on the edge of the pushing bar 7 in contact with the driven block 602. The distance from the path from point a 71 to point b 72 to the rotation center of the twist lid 4 gradually increases.

[0035] When the user rotates the twist lid 4 relative to the bottom lid 3, the contact point of the driven block 602 with the pushing bar 7 transitions from point a 71 to point b 72. During this process, the movable member 6 gradually slides in a direction away from the rotation center of the twist lid 4 until the hook part 601 is disengaged from the annular groove 102. The user can achieve the opening action of the cup lid 2 by rotating the twist lid 4 with a small angle once, which is very convenient to use.

[0036] Referring to Figures 5 - 7, a point c 73 is further provided on the edge of the pushing bar 7 in contact with the driven block 602.

[0037] When the user rotates the torsion cap 4 in the reverse direction relative to the bottom cover 3, the contact point of the driven block 602 with the pushing bar 7 transitions from point a 71 to point c 73. During this process, the moving member 6 gradually slides away from the rotation center of the torsion cap 4 until the hook portion 601 is disengaged from the annular groove 102. The user can quickly open the cup cover 2 by rotating the torsion cap 4 forward and backward at a small angle, which is very convenient to use. Preferably, the shape of the pushing bar 7 is symmetrically arranged, and the path shape and distance from point a 71 to point b 72 are equal to those from point a 71 to point c 73.

[0038] Reference Figure 8 , a force-receiving inclined surface 603 is provided on the side of the driven block 602 facing the pushing bar 7. The number of the force-receiving inclined surfaces 603 on the driven block 602 is two and they are symmetrically arranged with respect to each other.

[0043] The limit bars 302 have a simple structure, and the forces on both sides of the slider 604 are more uniform, and the sliding connection state is very stable.

[0044] The moving member 6 includes a connecting rod 605, and a positioning block 606 is provided on the connecting rod 605; the elastic device includes an elastic member 8 and a baffle 303. The baffle 303 is provided on the bottom cover 3, and an avoidance notch 304 for the connecting rod 605 to pass through is formed on the baffle 303. The elastic member 8 abuts between the baffle 303 and the positioning block 606.

[0045] The structure of the elastic device is simple and easy to manufacture; the provision of the avoidance notch 304 makes the structure inside the cup cover 2 more compact, which is beneficial to reducing the overall volume of the cup cover 2.
