Description
Technical field the utility model relates to the connection fittings between overturn cover and fixed body, especially for the rotation connection structure of overturn cover.
Background technique overturn cover is as a kind of turning shaft structure, on all multi-products application very extensive, overturn cover use such as buffet pot, washing machine, notebook computer, baking box, refrigerator-freezer and control box.Existing overturn cover is connected through the hinge mostly, while uncapping, to pay the power suitable with covering weight, when closing lid, because Action of Gravity Field overturn cover need support with hand, have the potential safety hazard that hand is arrived, when overturn cover falls rapidly, also easily produce Strike note, and long-term shock can affect product use; Moreover, to renovate with closing lid and all need to be all on board, overturn cover can not be parked halfway voluntarily, takes a lot of trouble inconvenience when use.
Model utility content the technical problems to be solved in the utility model is to avoid above-mentioned the deficiencies in the prior art part and proposes the rotation connection structure for overturn cover, laborsaving convenience while adopting the overturn cover of this rotation connection structure to uncap, when closing lid, can avoid clashing into, safe, not fragile, and overturn cover halfway arbitrary position stops voluntarily, easy to use.
The utility model solve the technical problem can be by realizing by the following technical solutions:
Design, make a kind of rotation connection structure for overturn cover, comprise rotating shaft, rotary shaft rack and rotating shaft end cap; Described rotating shaft is arranged in rotary shaft rack, and described rotating shaft end cap is installed in rotation on outside, rotary shaft rack two end part; At least one end of described rotating shaft inwardly has dell vertically, in the rotating shaft end cap of corresponding end, friction output shaft is installed, and this friction output shaft is in described dell; On described friction output shaft, be movably installed with fixed friction sheet and movable friction plate, fixed friction sheet is fixed in described dell; Also comprise torque spring, one end of this torque spring is fixed on rotary shaft rack, and the other end is fixed on friction output shaft; Described overturn cover is fixedly connected with rotating shaft, can rotate relative to rotary shaft rack, and overturn cover can drive rotating shaft end cap and the output shaft rotation that rubs while rotating.
The two ends of described rotating shaft all inwardly have dell vertically, in two rotating shaft end caps, friction output shaft are all installed, and fixed friction sheet, movable friction plate and torque spring are all provided with two covers.
Compared with the existing technology, the utility model is for the technique effect of the rotation connection structure of overturn cover: 1. due to the twisting force of torque spring, spring torsion can support the gravity of a part of overturn cover, laborsaving light while uncapping; When closing lid, the relative overturn cover gravity of torque spring produces reverse torsion moment, can offset a part of gravity, effectively avoids overturn cover to fall rapidly produced shock because of Action of Gravity Field; 2. the matching design of fixed friction sheet and movable friction plate, in the rotation process of overturn cover, produce friction torque, the torsion moment acting in conjunction of friction torque and spring can overcome the Action of Gravity Field of overturn cover, thereby ensure when overturn cover is arbitrarily angled at an arbitrary position to stop voluntarily, without by external force, easy to use.
Brief description of the drawings
Fig. 1 is the sectional structure schematic diagram of the utility model for the rotation connection structure of overturn cover;
Fig. 2 is the perspective view that described rotation connection structure is applied to buffet pot embodiment.
Embodiment
The utility model, for the rotation connection structure of overturn cover, as shown in Figure 1, comprises rotating shaft 10, rotary shaft rack 20 and rotating shaft end cap 30; Described rotating shaft 10 is arranged in rotary shaft rack 20, and described rotating shaft end cap 30 is installed in rotation on rotary shaft rack 30 outsides, two end part; The two end part of described rotating shaft 10 all inwardly have dell 11 vertically, and friction output shaft 40 is all installed in the rotating shaft end cap 30 at two ends, and this friction output shaft 40 is in described dell 11; On described friction output shaft 40, be movably installed with fixed friction sheet 50 and movable friction plate 60, fixed friction sheet 50 is fixed in described dell 11; Also comprise torque spring 70, one end of this torque spring 70 is fixed on rotary shaft rack 20, and the other end is fixed on friction output shaft 40; Described overturn cover 80 is fixedly connected with rotating shaft 10 by connecting plate 90, can rotate relative to rotary shaft rack 30, and overturn cover 80 can drive rotating shaft end cap 30 while rotating and the output shaft 40 that rubs rotates.
The utility model is applicable to the various products with flip horizontal lid, such as buffet pot, washing machine, notebook computer, baking box, refrigerator-freezer and control box etc. for the rotation connection structure of overturn cover.In different application, if process conditions allow, described rotating shaft end cap 30 can be one-body molded with friction output shaft 40.
Fig. 2 only provides the utility model and is applied to this embodiment's situation of buffet pot, and other is applied in this and does not enumerate.Below in conjunction with Fig. 1 and Fig. 2, lower working principle process of the present utility model is described.
In Fig. 2, mark 100 refers to buffet pot bottom support 100, and when use, bottom bracket 100 maintains static, and described rotary shaft rack 20 is fixed on described bottom bracket 100, and overturn cover 80 is rotated up and down relative to bottom bracket 100.When overturn cover 80 closure or openness, drive rotating shaft end cap 30 and friction output shaft 40 to rotate by connecting plate 90, friction output shaft 40 drive activity friction plates 60 rotate.
While opening overturn cover 80, the moment of torsion that torque spring 70 produces can partly overcome the gravity torque of overturn cover 80 rotation angles of living in, overturn cover 80 is opened easily laborsaving, in process after overturn cover 80 is unlocked, torque spring 70 is in being reversed energy accumulating state, can relative overturn cover 80 produce reverse torsion, movable friction plate 60 is with the 40 rotary synchronous rotations of friction output shaft simultaneously, produce surface friction drag with fixed friction sheet 50, the surface friction drag acting in conjunction that the reverse torsion of torque spring 70 and friction plate group produce, can overcome the Action of Gravity Field of overturn cover 80 completely, thereby overturn cover 80 can be stopped at an arbitrary position automatically, when closed overturn cover 80, overturn cover 80 drives rotating shaft end cap 20 and friction output shaft 40 to rotate by connecting plate 90, torque spring 70 is reversed produces reverse torsion, movable friction plate 60 is again with the 40 rotary synchronous rotations of friction output shaft simultaneously, produce surface friction drag with fixed friction sheet 50, movable friction plate 60 and the fricative resistive torque of fixed friction sheet 50 add that moment of torsion that torque spring 70 produces is greater than the gravity torque of overturn cover 80 corresponding operating angles, resist overturn cover 80 and fallen fast closure, only have and apply external force with hand and just can make overturn cover 80 drop to operating position.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
