Abstract

The utility model relates to a scald-proof safe water tap which comprises a plug body, a casing, a movable shaft core, a slide shaft, a spring, a handle and a cover body, wherein, the movable shaft core is arranged in the plug body; a spring is sheathed outside the movable shaft core; the slide shaft is transversely arranged in a round hole arranged at the top of the movable shaft core; the slide shaft and a shaft hole of the handle are connected; the shaft hole of the handle is designed into an n shape; the back side of the bottom of the handle is bulged downwards, forming a step, and thus, a self-locking angle is formed. The utility model has the advantages of artful structure and safe operation. A child can not know the skill, and the child has no force to open and close the water tap. In this way, the function of preventing scalding is performed.

Description

Anti-scald safe water tap

The utility model belongs to a kind of anti-scald safe water tap.

One press water tap and can dash one cup of boiling hot aromatic hot tea or coffee immediately gently, drinking machine has replaced hot-water bottle to enter huge numbers of families as a kind of household electric appliance owing to its convenient and swift health, but bring this while easily to have brought potential safety hazard also for the child of family to people, present household drinker generally all is to be placed in the place that child is very easy to run in the parlor.Child's imitation ability is strong especially, active, and the adult of family does not notice that slightly child will drink water or play with the water tap of drinking machine, accidentally will be scalded, even stays lifelong regretting.

The purpose of this utility model provides a kind of water tap that can self-locking, and the unlatching of this water tap needs certain skill and dynamics.

The utility model comprises cock body, housing, sliding shaft core, sliding axle, spring, handle, lid, shelve sliding shaft core in the cock body, sliding shaft core overcoat upper spring, the horizontal sliding axle of sliding shaft core top circular hole, sliding axle is inserted in the axis hole of handle, the axis hole of handle is designed to " n font ", and the bottom rear side of handle convexes to form one downwards from the locking angle.

Aforementioned " n font " axis hole comprises original area and self-locking zone, and separate by low sill in original area and self-locking zone, and along with the rotation of handle, sliding axle is displaced to the self-locking zone from original area in axis hole.

Particularly, " n font " axis hole, by equal tangent the forming of roundlet of two radiuses, the bottom, hole keeps tangent profile, form the low sill of projection like this at the place, point of contact, the top, hole allows one section bigger circular arc of radius that two roundlets are connected and forms one section bigger arc transition profile, and little circle radius and sliding axle radius make sliding axle can make certain displacement movement with the rotation of handle in this axis hole about equally.

The utility model structure is ingenious, and is safe in utilization, and especially child can not get a thorough understanding of skill wherein, also do not have strength to finish switch motion, so just plays the effect of anti-scald.

Accompanying drawing 1 is the utility model original shut state structural representation.

Accompanying drawing 2 is the utility model opening state structural representation.

Accompanying drawing 3 is the utility model self-locking closed condition structural representation.

Accompanying drawing 4 is the utility model self-locking closed condition structural representation.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises cock body (1), housing (2), sliding shaft core (3), sliding axle (4), spring (5), handle (6), lid (7), shelve sliding shaft core (3) in the cock body (1), the outer spring (5) that is inserted in of sliding shaft core (3), sliding shaft core (3) the top horizontal sliding axle of circular hole (4), sliding axle (4) is connected with the axis hole (12) of handle (6), the axis hole (12) of handle (6) is designed to " n font ", the bottom rear side of handle (6), stepped to lower convexity, form one from the locking angle (10).

Aforementioned " n font " axis hole (12), comprise original area (8) and self-locking zone (9), separate by low sill (11) original area (8) and self-locking zone (9), and along with the rotation of handle (6), sliding axle (4) is displaced to self-locking zone (9) from original area (8) in axis hole (12).

Particularly, " n font " axis hole (12), by equal tangent the forming of roundlet of two radiuses, the bottom, hole keeps tangent profile, form the low sill (11) of projection like this at the place, point of contact, the top, hole allows one section bigger circular arc of radius that two roundlets are connected and forms one section bigger arc transition profile, and little circle radius and sliding axle (4) radius makes sliding axle (4) can make certain displacement movement with the rotation of handle (6) in this axis hole (12) about equally.

Process is as follows: as shown in Figure 1, it is the original shut state of water tap, the same with common drinking machine water tap, sliding axle (4) is in the original area (8) of " n font " axis hole (12), as long as one press handle (6) gently, because arriving the radius of handle (6) fulcrum, sliding axle (4) changes (increasing), cock body (1) is raised, thereby tap is opened, and flow of hot water is come out; When opening state as shown in Figure 2, " n font " axis hole (12) were in smaller or equal to the direction of 45 degree, sliding axle (4) still was in the original area (8) of " n font " axis hole (12); Self-locking closed condition as shown in Figure 3, after making hot water, press toward next again, sliding axle (4) is owing to the pulling force of spring (5) and be directed downwards (more than or equal to 90 degree) of " n font " axis hole (12), sliding axle (4) will be displaced to self-locking zone (9) along " n font " axis hole (12) toward gliding, the fulcrum radius R that sliding axle this moment (4) is gone up any position to handle (6) equates, block lid (7) from the locking angle (10) on the handle (6), thereby make handle (6) no matter continue to rotate or upwards rotation, all cock body (1) up can not be carried, water tap can't be opened; As shown in Figure 4, to open again, pull outward after handle (6) up lifted, make from the locking angle (10) lid (7) that staggers, sliding axle (4) is walked around the original area (8) that protruding low sill (11) are displaced to " n font " axis hole (12), water tap returns to original closed condition, as shown in Figure 1.The continuous action that these are a series of, child can not get a thorough understanding of skill wherein, does not also have strength to finish, and so just plays the effect of anti-scald.
