Description

Pot with rotary cover

The utility model relates to a kind of Pot with rotary cover, and it belongs to tea set, the pottery of cooker or metallic article.

Now with kettle (as teapot, wine pot) though pot lid be to get the convenience, use smoothly, in use (when especially liquid is about to use up in kettle, when the former pot lid that is in horizontal direction progressively turns to vertical direction) pot lid always is easy to come off.So people in use always like a hand-held kettle, a hand steered lid, in case meet accident by chance, What is more, with a cord pot lid and handle connected together, this just can be regarded as is perfectly safe.In fact, this is also dangerous firm, health also not attractive in appearance.

The purpose of this utility model just provides in use a kind of, and pot lid can rotate voluntarily, blocks the Pot with rotary cover that closes and can not come off voluntarily automatically, uses safer, convenient.For achieving the above object, the utility model is taked following solution:

Circumference evenly leaves certain breach in the Tuo Gaitai upper edge; The stalk bar of certain thickness and width is set respectively in the circumference relevant position of pot lid body again; When breach on Tuo Gaitai of the stalk bar of pot lid body, the stalk bar can pass breach easily, lid and kettle can be coincide well, be positioned at holder this moment and cover stalk bar below the platform breach with the rotation of pot lid, can rotate at the Tuo Gaitai lower plane thereupon, as long as pot lid rotates, pot lid stalk bar and its breach that then passes the stalk bar well on one's body will produce dislocation, stalk bar after the dislocation will be covered decometer by holder, and firmly (this is because the stalk bar rotates the circular diameter that is drawn, interior circular diameter greater than Tuo Gaitai) pot lid can freely not come off, we can say, so long as stalk bar and its breach misplace, pot lid is then got being difficult for, so pot lid just more can freely not come off.

This line that obstructs the bar mid point as if the mid point vertical vertical line arrival the other side through the pot lid center of circle with a certain stalk bar on the pot lid is a countershaft, so parallel this countershaft and just have or not several through the parallel lines of the pot lid center of circle vertical vertical line, parallel lines are wherein arranged, it just in time passes through the periphery of pot lid cap, these parallel lines are symmetry axis if we make, so, on its symmetry axis, and the off-centre that all increases certain mass at the surfaces externally and internally of pot lid cap increases the weight of materials, make the suffered gravity off-centre of its pot lid, like this, pot lid after coincideing with kettle, in its use when progressively favouring vertical direction (be pot lid) by original horizontal direction since pot lid when first seated position, its off-centre increases the weight of particle not on the line of gravity of pot lid, so the pot lid after tilting will produce twisting under the gravity effect, we can say, liquid in kettle is more, when the angle of inclination of pot lid is very little, though pot lid can not twist, but it also can produce a twisting trend, minimizing along with liquid in the kettle, when the angle of inclination of pot lid increases to a certain degree, it just produces twisting, automatically deflection, pot lid after the deflection misplaces because of pot lid stalk bar on one's body covers the platform breach with holder, and pot lid just can freely not come off certainly yet.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 gives an example with the material object of kettle now, and marks each toponym.

Fig. 2 (a) is the upward view of Fig. 1 (a), and Fig. 2 (b) is the vertical view of Fig. 1 (b).

Fig. 3 is practical figure of the present utility model.

When Fig. 4 uses for the utility model, the optimum positional relationship figure that pot lid and kettle body are kept.

Fig. 5 (a) is the upward view of Fig. 3 (a), and Fig. 5 (b) is the vertical view of Fig. 3 (b).

Fig. 6 (a ') is that the A shown in Fig. 3 (a) is to view; Fig. 6 (a) is along the cutaway view of B-B line among Fig. 6 (a ').More than among each figure, figure (a) is pot lid; Figure (b) is the kettle body.

Wherein: 1, pot lid turn-knob, 2, pot lid cap, 3, pot lid off-centre increase the weight of decoration, 4, the interior off-centre of pot lid adds double-layer, 5, pot lid body, 6, pot lid stalk bar, 7, kettle mouth outer rim, 8, Tuo Gaitai, 9, holds in the palm and cover platform breach, 10, Hu Kou, 11, kettle body, 12, Hu Zui, 13, kettle handle.

Embodiment: Fig. 3 and Fig. 4 are pictorial diagram of the present utility model, from Fig. 3 (a) and Fig. 4 (a) as can be seen, on pot lid body 5, every 90 degree one section stalk bar 6 is set along circumference, on the holder lid platform 8 of Fig. 3 (b) and Fig. 4 (b), correspondingly spend every 90 along circumference, leave a long and wide breach 9 that obstructs bar 6 that is a bit larger tham, when pot lid any stalk bar 6 on one's body during over against the breach 9 of Tuo Gaitai, pot lid should be able to fall automatically, and is identical naturally with the kettle body on Tuo Gaitai 8.Hand is pinched pot lid turn-knob 1, twisting a little, the pot lid that coincide with kettle just can rotate on kettle, pot lid after the rotation, pot lid stalk bar covers the platform breach with holder and also misplaces thereupon, pot lid after the dislocation can only rotate, and can't separate, this is because the pot lid after coincideing, and its stalk bar is positioned at holder and covers the platform lower plane, and with its near, and there is not pressure again mutually, although pot lid body overall diameter is slightly less than holder and covers platform internal diameter (kettle mouth diameter), (otherwise the pot lid body can't insert Hu Kou) because the stalk bar is to place on the pot lid body, its two couples symmetry stalk diameter that bar connects is just necessarily greater than pot lid body diameter, (the pot lid body only can pass freely in the kettle mouth in pot lid body diameter as if kettle mouth slightly larger in diameter, not showing frame swings) so, two stalk bars institute diameters also should be greater than kettle mouth diameter, thereby the stalk bar that cover insertion of platform breach from holder is when misplacing because of the rotation of pot lid and breach generation, just covered decometer by holder, lid and kettle can only be relatively rotated, and can't separate, pot lid more can not come off voluntarily.Breach that platform stays 9 is covered in holder and pot lid stalk bar 6 circumferential positions are that symmetry is corresponding, as shown in Figure 5.

If we couple together the mid point of the mid point of Hu Zui and kettle handle with straight line, for Hu Zui and the very symmetrical standard kettle of handle, this line just should be through the center of circle vertical line of Hu Kou.When being noted that design, the position of the breach that stays will be symmetry axis with this above-mentioned line on the Tuo Gaitai, and each breach should be lived apart symmetrically in the both sides of its symmetry axis.If each breach mid point is considered as the arm of angle of summit in the center of circle to this straight line in the Hu Kou center of circle, so, platform breach mid point cover in four holders, and to guide the minimum angle of the four edges of the kettle heart and above-mentioned symmetry axis into should be 45 to spend, shown in Fig. 5 (b).

Shown in Fig. 3 (a) and Fig. 4 (a), at the upper surface of pot lid cap 2 off-centre is set and increases the weight of to decorate 3, its objective is: 1. utilize material therefor to increase the quality at this place, make the particle off-centre of pot lid; 2. will locate the materials of increase quality and make decoration, as, can make flowers, plants and trees, dragon and phoenix mountain celestial being, the beastly fowl of people and animals and worm for fishing honeybee butterfly etc., make it existing certain artistic characteristics, high enjoying value is arranged again; 3. this decoration also is the mark of pot lid to kettle mouth relative position, for strengthening the eccentric mass of pot lid, the off-centre of depending the pot lid outer surface alone increases the weight of to decorate, can't be met, off-centre adds double-layer 4 in the lid of certain thickness width so increased again within the inner surface of pot lid cap 2 and pot lid body 6, as shown in Figure 6.Simultaneously, the barycenter that should as far as possible make above the pot lid cap eccentric barycenter that increases the weight of to decorate and Gai Nei off-centre add double-layer during design is distributed in that to be connected two stalk bar mid points by pot lid center of circle vertical line be on the parallel lines of diameter, that is to say, look to periphery from the pot lid center of circle, their barycenter should be over against the mid point of a certain stalk bar.Certainly, under the prerequisite that does not influence the pot lid beautiful decoration, the barycenter that pot lid face off-centre increases the weight of to decorate is away from the pot lid center of circle, and its eccentric effect is just more comparatively obvious.

During use, increasing the weight of decoration on the pot lid cap is positioned at kettle mouth one side substantially, about twisting pot lid turn-knob, in the time of on the platform breach is covered in the holder below pot lid stalk bar on one's body forwards it to, but pot lid is free-falling just, coincide on Tuo Gaitai, at this moment, the radius lines that center of mass point that off-centre on the whole pot lid increases the weight of and kettle mouth mid point point to the kettle center of circle should constitute the angle (can be considered as angular vertex to the Hu Kou center of circle this moment) of 45 degree when hand-held kettle handle, when Hu Zui is progressively sagging, (as pouring) be not because the barycenter that initialization pot lid off-centre increases the weight of is on the vertically sagging gravity vertical of pot lid, so its particle can produce motion (will produce a movement tendency that is directed downwards at least) when pot lid slopes downwardly into certain angle under the gravity effect, twisting moment increases, pot lid deflects, and after the rotation, the pot lid breach that passes with it of the stalk bar of face on one's body misplaces, stalk bar after the dislocation is stuck in holder and covers in the platform, thereby pot lid can not come off voluntarily, be exactly Hu Zui straight down, pot lid can not come off yet.On the contrary, because Hu Zui straight down, the angle of inclination of pot lid increases, and the degree of misalignment of stalk bar and breach also strengthens, and pot lid is more firm.Because Hu Zui's is progressively downward-sloping, the barycenter that pot lid off-centre increases the weight of is also progressively near the line of gravity of pot lid, that is: pot lid is decorated and is progressively rotated to kettle mouth direction, when pot lid is decorated on the line of gravity that forwards pot lid to, when just pot lid is decorated kettle mouth over against vertical direction, pot lid just stops operating, and this moment, pot lid and kettle body just kept the position relation an of the best, as shown in Figure 4.

Need get when covering, hand is pinched to cover about turn-knob and is twisted, when each obstructs bar over against each breach, pot lid just can take off (to keeping the kettle and the lid of optimum position, only need twisting 45 degree, promptly desirable lid), this is because the breach that stays above the platform is covered in pot lid respectively obstruct bar and the holder of face on one's body, all be every 90 degree along circumference, and carry out equally distributed, so no matter be which root stalk bar, as long as at will over against a certain breach, other respectively obstructs bar also all is just in time to have aligned corresponding breach, and pot lid can both cover arbitrarily and get.Put the purpose that lid back pot lid is easy to forward to best location status for reaching, preferably putting when cover, just consciously with the pot lid decoration slightly to kettle mouth one side.
