Description
Technical field
The utility model is related to a kind of accessory of self-service tableware, and specifically a kind of bell suitable for buffet furnace delays
Falling unit.
Background technology
Buffet furnace is mainly used in restaurant, dining room and hotel, by the upper of service plate as a kind of container for containing food
A upset lid is installed by side can play certain insulation effect.The upset lid of existing meal stove causes it by slow descending device mostly
Uncapping or reversal rate is more uniform and slow when closing lid, such as Patent Office Publication is CN101986973B, entitled
" meal stove lid buffer device ", it, which is provided with the inside of sleeve on inwardly projecting flexure strip, friction core, has and flexure strip interference
The arc-shaped recess band of cooperation, the magnitude of interference between the arc-shaped recess band and flexure strip increases with the decline of upset lid；So its
Damping action power is linear change from small to large, i.e., damping force is in maximum rating when covering, therefore, is opened in upset lid
Starting stage needs to overcome the damping force of maximum and seem and uncap more arduously, thus brings inconvenience to eater.
In view of this, Patent Office Publication is CN104382458B, entitled " a kind of meal stove lid buffer device ", its support shaft
Torque spring, the first back-up ring and the second back-up ring respectively with the two ends phase clamping of torque spring are set between sleeve, wherein,
First back-up ring is fixedly arranged in support shaft, the second shield ring sleeve loaded in support shaft and with the inwall phase clamping of sleeve, torque spring
Store power during upset is covered gradually to increase, slow drop can be played and can easily be uncapped, but structural elements is more, in assembling
When it is complex, furthermore, because this structure is buffered merely by torque spring, spring is when originating buckling and latter end resilience
Elastic force is larger, and screen resilience does not have the soft of hydraulic damping power, though so the characteristics of having buffering and easily renovate, overall slow
Drop and the visual impression renovated or firmly sense when using it is not gentle enough and preferable.
The content of the invention
The purpose of this utility model is to provide for a kind of bell slow descending device suitable for buffet furnace, using existing damping
Buffer and be aided with torsion spring power-assisted, bell is remained at the uniform velocity to delay drop and renovate during upset is covered and easily smooth is more saved
Power, structure is simpler, assemble simpler.
Above-mentioned purpose is realized, the utility model is adopted the following technical scheme that, i.e., a kind of bell suitable for buffet furnace delays
Falling unit, the main peace joint chair that can be socketed including one within the barrel, cylinder is connected with bell, and the peace joint chair is by symmetrically arranged
The first half and lower half fold fastening composition, and the two ends of peace joint chair, which are symmetrically respectively provided with axle bed, axle bed, is equiped with Damping rotation shaft, axle
It is additionally provided with seat in spring base, spring base and is provided with a torque spring being socketed between Damping rotation shaft and axle bed, wherein torque spring
One end be connected to the shaft end of Damping rotation shaft and rotated with the rotation of shaft end, the other end of torque spring is connected on axle bed
In blocked hole, the storage power produced when torque spring is overturn with bell gradually increases or reduced to be rigid, and Damping rotation shaft is covered in meal
The flexible effect of certain damping buffering, mutually auxiliary combination are then kept during upset.
To improve the fastness for folding fastening, the first half tangent plane of above-mentioned peace joint chair is provided with some connecting poles, correspondingly
Lower half is then provided with and connects hole with connecting pole grafting.
For preferably Damping rotation shaft is connected on axle bed, above-mentioned Damping rotation shaft is provided with clamping raised line, and axle bed is provided with and card
Connect the neck of raised line matching.
For convenience of the installation of torque spring, one end of above-mentioned torque spring is bent to a polygonal hole along spring ferrule central
Socket end, socket end be socketed on the matching shaft end of Damping rotation shaft and rotated with the rotation of shaft end, torque spring it is another
End is bent to joint end along the external diameter of spring lasso and is connected in blocked hole.
It is preferred that, it is a slot that above-mentioned socket end matches with the shaft end.
Installed for convenience of bell, above-mentioned peace joint chair is provided with installation screw.
Using compared with prior art, the utility model has the following advantages that after above-mentioned technical proposal：
One is that Damping rotation shaft and torque spring are respectively equiped with the two ends of peace joint chair, and peace joint chair is that upper lower half folds fastening
Form, it is simple in construction and convenient for assembly.
Two be that damping dress axle is aided with torque spring progress power-assisted in rotation process, is produced when torque spring is overturn with bell
Storage power gradually increase or reduce to be rigid, Damping rotation shaft then keeps the flexible of certain damping buffering to make when bell overturn
With, mutually auxiliary combination, because torque spring is in maximum energy accumulating state when being opening bell first, thus can be more easily laborsaving
With it is smooth；Next to that when covering bell, because torque spring is now in the relaxation state of maximum, only Damping rotation shaft is slow
Punching is acted on, light to draw bell just overturn；In addition, this symmetrical configuration is provided with two Damping rotation shafts and correspondingly sets two torsion bullets
Spring, stress and rotation, which are more balanced, to be consolidated, and the torque spring produced by declining with bell deforms bigger, it is ensured that bell can be more at the uniform velocity
Slow drop until cover, perception is more preferably.

Embodiment
As illustrated, a kind of bell slow descending device suitable for buffet furnace, main to be socketed within the barrel including one
Pacify joint chair, cylinder by be located at peace joint chair on installation screw 14 be connected with bell, pacify joint chair by the symmetrically arranged first half with
Lower half by connecting pole 13 and it is corresponding connect hole 5 and plug clip be combined into, the two ends of peace joint chair are symmetrically respectively provided with axle bed
3, spring base 4 is additionally provided with axle bed 3, and one end of torque spring 11 is bent to the socket of a slot 10 along spring ferrule central
End 12, socket end 12 be socketed on the matching shaft end 8 of Damping rotation shaft 7 and rotated with the rotation of shaft end 8, torque spring 11 it is another
External diameter of the one end along spring lasso is bent to joint end 9 and is connected in blocked hole 1, and Damping rotation shaft 7 is provided with clamping raised line 6, card
Raised line 6 is connect to be connected in the neck 2 of matching.The storage power that torque spring 7 is produced when being overturn with bell for it is rigid gradually increase or
Reduce, Damping rotation shaft 7 then keeps the flexible effect of certain damping buffering, mutually auxiliary combination when bell is overturn.
When installing and using, the socket end 12 of torque spring 11 is socketed on Damping rotation shaft 7 by shaft end 8, by torsion spring
Joint end 9 be connected in the blocked hole 1 of peace joint chair, then the upper lower half for pacifying joint chair is interlocked compressions, makes connecting pole 13 slotting
It is connected on to connect and close connection is formed in hole 5, upper bell is connected by installation screw 14 after set upper bush, then shaft end 8 is connected to
Body of heater is fixed, now, as shown in fig. 7, when covering bell, the light clamping drawn bell and drive peace joint chair linkage torque spring 11
End 9 is rotated in the direction of the arrow, and because torque spring 11 is now in the relaxation state of maximum, the only buffering of Damping rotation shaft 7 is made
With, at the uniform velocity delay drop until covering in bell upset, will not be with stove seat water pond hair by clashing.As shown in figure 8, and opening stove
Gai Shi, because torque spring 11 is in maximum deformation energy accumulating state, thus under the effect of its power-assisted, uncapping can seem lighter
Pine is laborsaving and smooth.
