Abstract

The utility model discloses a safety switch of a cup cover. A movable cover is pivoted on a cover body, a switch and a safety button are pivoted on the movable cover, one end of the switch is provided with a fastening hook capable of being fastened in a groove of the cover body and can be used as a force-resisting end, the other end of the switch is used as a force-applying end, a spring is arranged between the movable cover and the cover body, and the safety button is disposed on the movable cover, can move relative to the movable cover and is provided with a projection. When the movable cover covers the cover body and the switch is not stressed by external force, the elasticity of the spring is acted on the force-applying end of the switch so that the hook is fastened to the groove of the cover body, and the safety button can be pushed so that the projection stops the force-applying end of the switch and the force-applying end can not be pressed to avoid opening the movable cover mistakenly. When the movable cover is required to be opened, the safety button is pushed so that the projection is separated from the force-applying end of the switch, the force-applying end of the switch can be pressed so that the fastening hook is separated from the groove of the cover body, and the movable cover flicks by the aid of the torsion spring.

Description

The bowl cover safety switch

Technical field

The utility model relates to the switching device that is used for as containers such as thermos cup, vacuum flask, and particularly a kind of have the user's of preventing false touch switch and open lid accidentally, the safety switch that causes content liquid to flow out.

Prior art

The small-sized vacuum flask or the thermos cup that at present generally are used and conveniently carry, all include a vessel and a lid, this lid and vessel have two kinds of compound modes: first kind is to adopt spiral way that lid is locked in vessel, in the time will drinking boiling water, lid must be outwarded winding, after finishing off again with the lid screwing hermetic, in case cup in water ooze out, the vacuum flask of the sealed lid of this kind spiral or thermos cup are owing to using by one-handed performance, so comparatively inconvenient.Second kind then is the opening edge that lid is articulated in vessel, and torque spring is set in its articulated section, and the fastening switch being set in vessel port and lid edge, the user can be covered on vessel port with lid, utilizes simultaneously to fasten switch lid is fixed in vessel port and sealing; In the time will drinking water, the user can make Cover opening by the elastic force of torque spring as long as run the pass jointly with the one-handed performance Pressing fastener, when finishing off, lid is covered again.The design of aforementioned second kind of known vacuum flask or thermos cup is no doubt because can one-handed performance and more convenient, but its shortcoming be fasten switch easily by false touch and mistake with Cover opening.

The utility model content

The purpose of this utility model is, the lid that solves existing vacuum flask or thermos cup is adopted the pivot joint mode with vessel and cooperated and fastens switch, easily when not using by false touch fastening switch and by mistake with the problem of Cover opening.

The bowl cover safety switch that the utility model provides, be at a lid body removable cover that is pivoted, and removable cover be pivoted a switch with a safety knobs is set, one end of switch has can fasten the clasp that is located at the groove that covers body and as the drag end, the relative other end of switch is as the force side, and a spring is located between removable cover and the lid body; Safety knobs is located at removable cover and can be relatively moved with removable cover, and has a teat in safety knobs.When covering, removable cover covers body and switch is not subjected under the state of external force, act on the force side of switch by the elastic force of spring, clasp is fastened cover the groove of body, this moment, the user can promote the force side that safety knobs makes its teat stop switch, the force side can't be pressed and opened by mistake and opened removable cover; When desire was opened removable cover, the user needs to promote earlier safety knobs broke away to the stopping of the force side of switch its teat, force side that can push switch and make clasp break away from the groove that covers body, and then by torque spring removable cover is flicked.

As a kind of selection, can one guide block be set at removable cover, safety knobs then is provided with a guide groove that is used for being slidingly matched this guide block, when the user promotes safety knobs, system moves guide block in guide groove, safety knobs and removable cover are relatively moved, with the teat force side that whether stops switch of control safety knobs.

The utility model has the advantages that at the lid body removable cover that is pivoted, then a be pivoted a switch and safety knobs is set of removable cover, when removable cover when being covered on the state of body, the user can promote safety knobs toward first direction, lid make safety knobs switch be pinned and can't be pressed, even also can't be unlocked; Otherwise, when the user desires to drink water, can one-handed performance this safety knobs be promoted toward second direction, just can remove the switch that is lockable, and then can push switch and open removable cover.

The specific embodiment

Fig. 1 shows the embodiment of safety switch application in thermos cup or vacuum flask, and it includes lid body 1, a removable cover 2 and a vessel 3; Lid body 1 is the upper end of being located at

vessel

3,2 of removable covers are located at and are covered body 1 top, removable cover 3 further is provided with a switch 23 and a safety knobs 25, when switch 23 is pressed, removable cover 2 can be opened, 25 of safety knobs are used for switch 23 is pinned and can't be pressed, but or remove the locking of switch 23 and push switch.

As shown in Figure 2, the bowl cover safety switch that provides, be provided with internal thread for the external screw thread that is locked on vessel 3 upper ends below lid body 1, the top of lid body 1 then is provided with an outlet 11 of flowing out for liquid, and the outer side surface of lid body 1 is provided with the groove 12 of a suitable size.Lid body 1 top one side is provided with a lug, and articulates a removable cover 2 with a pivot 21, and the removable cover 2 of pivot 21 peripheries is provided with a torque spring 22 with covering between the body 1, and torque spring 22 has and puts on removable cover 2 with its elastic force that flicks; The top of removable cover 2 is provided with a guide block 24 that is level.One switch 23 and a safety knobs 25 are provided in addition; Switch 23 is L-shaped, switch 23 is hubbed at removable cover 2 with a tip axle 232, one end of switch 23 has the clasp 231 that can fasten described groove 12 and as the drag end, the relative other end of switch 23 is as the force side, one spring 233 is located between removable cover 2 and the lid body 1, spring 233 can apply elastic force to the force side of switch 23, makes switch 23 rotation and make clasp 231 shift to groove 12.The structure of safety knobs 25 ties up to the one end one teat 251 is set, the other end of safety knobs 25 then forms a guide groove 252 that can be slidingly matched with aforementioned guide block 24, guide block 24 is matched with guide groove 252 and safety knobs 25 and removable cover 2 are finished cooperate, the user can promote safety knobs 25 and removable cover 2 relatively moves.
