Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

For ease of understanding, the specific structure and operation of the utility model will be further described herein with reference to the accompanying drawings:

the specific structure of the utility model is shown by referring to fig. 1-9, and the main structure of the cover body 10 comprises a connecting part 11 with a liquid outlet 111 eccentrically arranged at the top and a rotary cover part 12 coaxially and rotatably matched with the top of the connecting part 11 for opening or sealing the liquid outlet 111 in the rotating process. The rotary opening and closing mode of the cap screwing part 12 is adopted, and the situation of false touch opening is not easy to happen relative to the button opening mode. In addition, in the practical implementation, the size of the spiral cover part 12 can be controlled, so that the coverage area of the spiral cover part 12 to the liquid outlet 111 is larger, and even if the spiral cover part 12 deflects due to the false touch or vibration, the good sealing effect on the liquid outlet 111 can be maintained. Further, a locking part 14 capable of moving up and down is slid on the limit groove A of the connecting part 11, the positioning pin 142 of the locking part 14 can form locking fit with the pin hole 121 of the cap screwing part 12 in the closed state along the axial direction, unlocking operation of the pin hole 121 and the positioning pin 142 can be realized when the locking part 14 moves down along the axial direction, and when the locking part 14 is in implementation, the cap screwing part 12 can be opened in a rotating way only by pressing down the locking part 14 to separate the positioning pin 142 from the pin hole 121, so that unlocking of the locking part 14 and opening of the cap screwing part 12 are convenient and fast, and the cap screwing part 12 has better locking effect.

Further, as shown in fig. 1, an unlocking button 13 capable of moving up and down is further provided on the connection portion 11, and during the process of descending the unlocking button 13, the locking portion 14 can be pressed to slide down until the positioning pin 142 is separated from the pin hole 121 to unlock, and the unlocking of the locking portion 14 is achieved by pressing the unlocking button 13. After that, after the unlocking button 13 continues to press the locking portion 14 downward to separate from the limiting groove a, the locking portion 14 rotates around the axis of the connecting portion 11, so that the positioning pin 142 and the pin hole 121 are dislocated in a top view, and in this state, the positioning pin 142 cannot be locked with the pin hole 121 in an inserting manner due to the dislocating of the positioning pin 142 and the pin hole 121 in a top view, so that the cap screwing portion 12 is in a state capable of being turned and opened at any time. In this embodiment, the unlocking state of the rotary cover 12 can be maintained continuously without applying downward pressing force to the unlocking button 13 after the unlocking button 13 is pressed downward, so that the rotary cover 12 can be rotated again after the unlocking button 13 is pressed in the opening process, and the rotary cover 12 is applied again without pressing the unlocking button 13, thereby further ensuring the convenience of opening the rotary cover 12.

In order to realize that after the unlocking button 13 continues to press down and the locking portion 14 is separated from the limiting groove a, the locking portion 14 rotates around the axis of the connecting portion 11, so that the positioning pin 142 and the pin hole 121 are dislocated in a top view, and in practical implementation, there are various embodiments.

In embodiment 1, specifically, as shown in fig. 4 and 5, a wedge 141 and a limiting groove a are used as a driving unit, and the driving unit is configured as several groups circumferentially distributed around the axis of the sleeve 112, and in the present application, four groups of driving units are preferably used. The locking part 14 is lifted and slid in the limit groove A by the wedge 141, the bottom of the unlocking button 13 and the top wedge surface of the wedge 141 form wedge matching, in the descending process of the unlocking button 13, the unlocking button 13 presses down the wedge 141 until the wedge 141 is separated from the current limit groove A, then, the unlocking button 13 continues to press down the wedge 141, and the wedge 141 drives the locking part 14 to rotate along the forward direction due to the wedge matching until the wedge 141 slides into the limit groove A of the next driving unit, and at the moment, the spiral cover part 12 is in the forward direction openable rotation state. In this embodiment, since the plurality of driving units are provided, when the wedge 141 enters the next limit groove a, the wedge is opened along with the forward rotation of the cap screwing part 12 until the pin hole 121 rotates right above the positioning pin 142 again, the positioning pin 142 can be reset and inserted into the positioning pin 142 upwards, so that the opened cap screwing part 12 can be locked again, and the phenomenon that the opened cap screwing part 12 generates spin action to disturb the pouring of the liquid from the liquid outlet 111 is prevented.

In embodiment 2, a torsion spring is provided on the rotation shaft of the locking portion 14, and after the locking portion 14 is separated from the limiting groove a, the torsion spring drives the locking portion 14 to rotate around the axis of the connecting portion 11.

In order to further improve the convenience of closing the screw cap 12 after opening, on the basis of the embodiment 1, as shown in fig. 2-5, the limit groove a comprises a return inclined tooth groove 1123 which can form inclined wedge fit with the wedge 141, the chute bottom 11232 of the return inclined tooth groove 1123 gradually inclines upwards along the forward rotation direction of the screw cap 12, the deep groove side of the return inclined tooth groove 1123 is axially penetrated with a through hole 1122 for inserting the unlocking button 13, and the vertical groove wall 11231 of the deep groove side forms a guide wall for keeping the wedge 141 to generate vertical lifting motion. When the unlocking button 13 presses the wedge 141 to slide below the current vertical groove wall 11231, the unlocking button 13 continues to press the wedge 141 and causes the wedge 141 to rotate in the forward direction until the wedge 141 slides into the next return inclined tooth groove 1123, after which the screw cap 12 rotates in the forward rotation direction to open, so that the positioning pin 142, which is originally dislocated in the top view, is realigned to the pin hole 121 and elastically returns upward and is inserted into the pin hole 121. Since the wedge 141 is elastically abutted against the chute bottom 11232 in this state, a friction force preventing the wedge 141 from rotating in the reverse rotation direction is formed between the wedge 141 and the chute bottom 11232, that is, an elastic locking state in which the opened screw cap portion 12 rotates in the reverse rotation direction is formed between the wedge 141 and the chute bottom 11232 of the next return chute slot 1123, and in this elastic locking state, not only a certain locking friction force preventing the wedge 141 from rotating in the reverse rotation direction is provided, but also when a greater locking friction force is manually applied to the screw cap portion 12 in the reverse rotation direction, the positioning pin 142 is pushed by the hole wall of the pin hole 121 of the screw cap portion 12 to move, thereby driving the locking portion 14 and the wedge 141 to rotate in the reverse direction as a whole until the wedge 141 moves into the previous return chute slot 1123. In this embodiment, after the cap screwing part 12 is opened in the forward direction, when the cap screwing part 12 is closed in the reverse direction, the cap screwing part 12 can be closed in the reverse direction without pressing the unlocking button 13 again, and the convenience of opening and closing the cap screwing part 12 is further improved.

In addition, in order to prevent the cap 12 from rotating reversely in the initial closed state, as shown in fig. 2, a connection block 113 is further fixed to the connection portion 11. When the cap portion 12 is in the closed state and the positioning pin 142 is axially locked with the pin hole 121, the positioning pin 142 abuts against the connection block 113 to prevent the cap portion 12 in the closed state from rotating in the reverse rotation direction.

Further, as shown in fig. 2, the lower portion of the positioning pin 142 is outwardly protruded to form a rotation stopping block 1421, the connection blocks 113 are provided in at least two, and one of the connection blocks 113 prevents the rotation of the cap 12 in the closed state in the reverse rotation direction, where the connection block 113 is defined as a first connection block 113, and the other connection block 113 defines a rotation angle at which the locking portion 14 rotates in the forward rotation direction, where the connection block 113 is defined as a second connection block 113, preventing the user from pressing the unlocking button 13 again after the cap 12 is opened, causing the locking portion 14 to rotate again in the forward rotation direction, and eventually causing the first connection block 113 to fail to exert an effect of preventing the cap 12 in the closed state from rotating in the reverse rotation direction, whereby the closing direction of the cap 12 is effectively defined by the second connection block 113.
