Preferably, also axle sleeve is set with between described bolster and torque spring.
Preferably, the mode that described supporting base is threaded connection is connected with sleeve.
Preferably, the two ends of described bolster are also provided with bearing, and described supporting base comprises the external thread part carrying out with the inwall of sleeve being connected and the recess holding also rigid bearing, and the opening of described recess is towards torque spring.
Preferably, the inwall of described sleeve is provided with groove, the radially outer edge of the second back-up ring is provided with the projection extended in groove.
Preferably, the two ends of described bolster are also provided with the snap ring with the clamping of left and right bearing phase, and the cross section of the spindle nose of described bolster is polygon, and card Ring current distribution is provided with the polygonal through hole with the spindle nose phase clamping of bolster.
Preferably, described snap ring is fixed by screws in the end of bolster.
Preferably, described bolster is also set with silica gel pad.
Beneficial effect is: compared with prior art, meal stove lid buffer device of the present utility model, owing to have employed said structure, thus make the power that stores of torque spring can play power-assisted effect to opening overturn cover, and overturn cover is contacted with water pond lentamente, avoids overturn cover and water pond to occur to clash into fiercely.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the decomposing schematic representation of meal stove lid buffer device of the present utility model;
Fig. 2 is the partial sectional perspective view of meal stove lid buffer device of the present utility model;
Fig. 3 is spring structure schematic diagram of the present utility model;
Fig. 4 is the structural representation of the second back-up ring of the present utility model.
Detailed description of the invention
Meal stove lid buffer device as Figure 1-Figure 4, it comprises the left and right bearing 11,12 for being arranged on grate, is provided with bolster 2 and sleeve 4 between left and right bearing 11,12.Sleeve 4 is for being connected with overturn cover, and it is outside and can rotate relative to bolster 2 that sleeve 4 is arranged on bolster 2, and the two ends of sleeve 4 are provided with support bolster 2 and the supporting base 7 be removably connected with sleeve 4.Torque spring 3, first back-up ring 51 and the second back-up ring 52 is also set with between bolster 2 and sleeve 4.The two ends of torque spring 3 respectively with the first back-up ring 51 and the second back-up ring 52 phase clamping, wherein, first back-up ring 51 is fixedly arranged on bolster 2, the second back-up ring 52 to be set on bolster 2 and with the inwall phase clamping of sleeve 4, the power that stores of torque spring 3 increases gradually in overturn cover closing lid process.This device makes the power that stores of torque spring 3 can play power-assisted effect to opening overturn cover, and overturn cover is contacted with water pond lentamente, avoids overturn cover and water pond to occur to clash into fiercely.
Preferably, the radially outer edge that the two ends of torque spring 3 are provided with on clamping part 30, first back-up ring 51 and the second back-up ring 52 that arrange along its axis direction is provided with the breach 53 matched with clamping part 30.
Preferably, for reducing the radial dimension of bolster 2 and being convenient to processing and manufacturing, be also set with axle sleeve 20 between bolster 2 and torque spring 3, axle sleeve 20 can adopt plastic material to make.
