Description
Technical field
The present invention relates to a kind of meal stove.
Background technology
Existing meal stove, the use state of meal bell is generally; The closed condition of 0 degree, the client who opens about 90 degree uses state and is opened for the use state that waiter about 160 gets the meal basin.Be used for the center of gravity of meal bell not at the pivot of bell of eating, the position of centre of gravity of meal bell and the arm of force of gravity change along with the rotation of meal bell, 0 the degree closed condition the time, see that Fig. 1, gravity vertical overlap with rotating shaft, the arm of force of gravity and moment are 0, and the angle of opening along with the meal bell becomes big, the arm of force of gravity and moment are also along with becoming big, open 90 when spending, see Fig. 2, the arm of force of gravity and moment are maximum.The main effect of damping axle is to produce damping torque, stops the meal bell to rotate under the gravity effect, and the meal bell can both be stopped in free position, optional position, and is easy to use.
A product that generally use in present market, patent announcement number is in the patent of CN201775472U, uses friction-type rotation one-way damper, and the meal stove is opened arbitrarily angled, damping force is all the same, when beginning to open, client's feel resistance maximum, 90 when spending, client's feel resistance minimum, not only feel is bad, and when friction piece weares and teares, will stop incessantly in the use location of 90 degree.In the global design of meal stove, see Fig. 3 in addition, jackshaft 1 is not the axle that connects inside casing 2 and housing 3, and inside casing 2 is connected with housing 3 need arrange connector 4, has both increased cost, not attractive in appearance again, and shell 5 is the sanitation and hygiene that are not easy to again attractive in appearance neither.
Another product that generally use in present market, in the patent of patent announcement C N101617904A, see Fig. 4, use the lip-deep pressure difference of the different radii of flexure strip 6 on friction core 8, be the frictional force difference, the variation of 0 to 90 degree and 90 to 180 degree frictional resistance comes the variation of the moment of balance meal bell gravity.Flexure strip 6 is that line contacts with the surface of friction core 8 or is that facet contacts that the wearing and tearing easily of the surface of friction core 8 influence service life.This patent is not used unilateral bearing, and resistance was bigger when the meal bell was closed, and feel is bad.Working chamber 7 oral areas are outside in addition, and friction core 8 large end faces expose outside, the neither sanitation and hygiene that are not easy to again attractive in appearance.
Summary of the invention
The feel that existing meal stove exists in the meal bell uses is relatively poor, wearing and tearing are big in order to overcome, service life short deficiency, feel is all good when the invention provides a kind of unlatching, closed meal bell, and it is little to wear and tear, the meal stove of long service life.
The present invention is in order to solve the problems of the technologies described above, and the technical scheme of employing is:

Shown in Figure 6, the both sides of described inner frame 17 are installed 16, two adapter sleeves 10 of axis respectively and are fixedlyed connected with the both sides of outside framework 9.Described adapter sleeve 10 is provided with protruding neck 22 towards the inner frame side, and described protruding circle is positioned at described protruding neck 22, has the notch 23 that passes through for block on the described protruding neck 22.
Or fixedly connected with adapter sleeve 10 respectively in the both sides of described inner frame 17, and the both sides of described outside framework 9 are installed axis 16 respectively.Described adapter sleeve 10 frame side outward is provided with protruding neck 22, and described protruding circle is positioned at described protruding neck 22, has the notch 23 that passes through for block on the described protruding neck 22.
More than two kinds of assembling modes can select arbitrarily, wherein a kind of assembling mode is all adopted in both sides, perhaps both sides adopt different assembling modes all can realize the present invention.
Described block is the bending block.Described block can form with bending, can reduce cost.
Further again, described set angle is between 0 ° to 120 °, for example can select 0 °, 30 °, and 60 °, 90 °, 120 ° etc.; Certainly, also can be set at other angles as required, for example 150 °.
Further, the set angle of the limit opening on the protruding circle of two rotary sleeves is identical.For example all be made as 0 °, 30 °, 60 °, 90 °, 120 ° etc.
With reference to Fig. 8 and Fig. 9, in the present embodiment, the set angle of the limit opening on the protruding circle of a rotary sleeve is 0 °, and the set angle of the limit opening on the protruding circle of another rotary sleeve is 90 °.Certainly, also can select other the different compound mode of angle for use.
The meal grate left end of present embodiment is provided with first rotary sleeve 15 of 0 degree opening, and right-hand member is provided with second rotary sleeve 21 of 90 degree openings.
About the meal grate of meal stove, be respectively arranged with damper assembly (being the unidirectional damping axle), on the meal grate outside framework 9 is arranged, described outside framework 9 is provided with adapter sleeve 10, adapter sleeve 10 inwalls cooperate with friction piece 11 cylindricals, the interior circle of friction piece 11 and the cylindrical of expander 12 closely cooperate, interior circle and the unilateral bearing overcoat 13 of expander 12 closely cooperate, the interior circle of unilateral bearing 14, needle roller on definite unilateral bearing 14 inner rings of saying so rolls with rotary sleeve 15 cylindricals and cooperates, the interior circle of first rotary sleeve 15 cooperates with axis 16, and an end of axis 16 cooperates with inner frame 17.Also be combined with swinging fork 18 on the described axis 16, swinging fork 18 and meal bell 19 close-fittings, the block 20 on the swinging fork 18 cooperates with first rotary sleeve 15.
When meal bell 19 was installed, the block 20 of swinging fork 18 was crossed the protruding neck 22 on the adapter sleeve 10, and the notch 23 of last setting enters in the protruding neck 22, fell on first rotary sleeve 15 to arrange in the opening 24, and the bell 19 of eating this moment is 0 degree state.
When client opens meal bell 19 when setting a table, meal bell 19 rotates to 90 degree from 0 degree, this moment is because the opening 24 of second rotary sleeve 21 in the unidirectional damping axle of the right is 90 degree, block 20 on the swinging fork 18 does not contact with the side of the opening 24 of second rotary sleeve 21 when 0 degree is swung to 90 degree, second rotary sleeve 21 does not rotate, namely the right unidirectional damping axle is not worked, to the 19 undamped effects of meal bell.The opening 24 of first rotary sleeve 15 in the unidirectional damping axle of the left side is 0 degree, block 20 on the swinging fork 18 remains with the side of the opening 24 of first rotary sleeve 15 when 0 degree is swung to 90 degree and contacts, first rotary sleeve 15 rotates along with the rotation of meal bell, and left side unidirectional damping axle has damping action all the time to meal bell 19.Open meal bell 19 easily and steadily.When meal bell 19 arrives 90 degree states, block 20 on the swinging fork 18 of the right begins to contact with the side of the opening 24 of second rotary sleeve 21, two unidirectional damping axles all play damping action to the rotation of meal bell 19 about this moment, resistance obviously strengthens, meal bell 19 can rest on 90 degree positions, uses for client.
When will building meal during bell 19, the block 20 on the right swinging fork 18 does not still contact with the side of the opening 24 of second rotary sleeve 21 during swing to 90 degree at 0 degree, to the bell 19 undamped effects of eating.One-way shaft in the unidirectional damping axle of the left side works, to the also undamped effect of meal bell 19.Can easily cover meal bell 19.
If take out or place the interior vessel of meal stove, make meal bell 19 open bigger angle, when spending greater than 90, overcome the resistance that needs two unidirectional damping axles, with bigger power.
