Description
Technical field
The utility model relates to a kind of single direction rotation damper, particularly a kind of rotation damper for the hinge axis during opening and closing such as automotive trim, small household appliances, furniture, sanitary equipment.
Background technique
At present, the parts of some devices rotate around axle, as automobile seat arm, lavatory lid etc., main adopt three kinds of structures: the first directly uses pinned connection, and can send the very large sound opening, when putting down, the impact caused is large; The second adopts spring buffer, and easily again cannot use because of spring corrosion, working life is short; The third, install a kind of rotation damper realizing buffering by damping grease, but the resistance produced when this design exists unlatching or resets is identical, makes the shortcoming comparing effort the side opening or close direction.
In the past, delayed slow-motion object for the cover plate etc. made to side's reinforcing of opening or closing direction, there is the device employing rotation damper.Common rotation damper main body has: damper shell, and its inside is sealed with viscous fluid (damping oil); And rotor, it possesses rotor blade and rotor shaft, this rotor blade is contained in damper shell, and this rotor shaft is projecting and give prominence to from damper shell on rotor blade, and rotation damper is combined with rotary components such as the transmission devices that rotates of should decaying at rotor shaft place.The general transmission device combined in the outer end of rotor shaft is planetary gear structure, as shown in open source literature [CN10368808].The planetary gear device structure of this transmission is more complicated, and structure takes up room greatly, and assembly is many, application of not easily accomplishing scale production.
Model utility content
The purpose of this utility model is to provide a kind of unidirectional resistance rotation damper with independent fitting seat, only produces damping force to unidirectional rotation, and structure is simple, is easy to batch production.
Above-mentioned purpose is achieved through the following technical solutions:
With the unidirectional resistance rotation damper of independent fitting seat, include damping main body, it is characterized in that: described damping main body is outside equipped with fitting seat, damping bodied rotor shaft extension goes out fitting seat mesopore and is connected with gear, between rotor shaft and fitting seat mesopore, there is space, the outer side wall of damping body shell has outer teeth, and described outer teeth match with the interior teeth of fitting seat inner ring, and wherein fitting seat inner ring only has sub-fraction to have interior teeth.
Described damping main body includes at the bottom of housing lid, seal ring, rotor shaft and housing, be connected to form closed cavity at the bottom of housing lid and housing, cavity inside is equipped with damping grease, in rotor shaft build-in cavities, rotor shaft outer end is stretched out outside shell, and seal ring seals up coordinating of rotor shaft and cavity.
The both sides of described fitting seat have the extending end of fixed screw holes, and extending end is symmetrical with central axis.
In described fitting seat, teeth are positioned on the inwall of one of them extending end, and another extending end inwall is without interior teeth.
The outer side wall of described damping body shell is evenly equipped with outer teeth.
Adopt the unidirectional resistance rotation damper of said structure, during unlatching, the gear of damper is by external force, and be close to fitting seat inner ring without interior teeth side by rotor shaft band dynamic damping entire body, now damping main body dallies in fitting seat, does not stress; During reset, the stressed fitting seat that is close to of damper has interior teeth side, and the outer teeth of damping main body engage with teeth in fitting seat, thus damping main body is started working, and realizes damping buffering.Have employed independently fitting seat structure, structure is very simple, utilizes teeth meshing engagement structure open between fitting seat and damping main body, is easy to realize, production can reduces cost of production, can be mass-produced.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1 ~ 3, with the unidirectional resistance rotation damper of independent fitting seat, include damping main body 3, described damping main body 3 to include at the bottom of housing lid 4, seal ring 5, rotor shaft 6 and housing 7, at the bottom of housing lid 4 and housing, 7 are connected to form closed cavity, and cavity inside is equipped with damping grease, in rotor shaft 6 build-in cavities, rotor shaft 6 outer end is stretched out outside shell, and seal ring 5 seals up coordinating of rotor shaft 6 and cavity.
As shown in figures 1-8, described damping main body 3 is outside equipped with fitting seat 2, damping bodied rotor axle 6 stretches out fitting seat mesopore 21 and is connected with gear 1, between rotor shaft outer end 61 and fitting seat mesopore 21, there is space, the outer side wall of damping main body 3 housing have outer teeth 71, described outer teeth 71 match with the interior teeth 22 of fitting seat inner ring, and wherein fitting seat 2 inner ring only has sub-fraction to have interior teeth 22.The both sides of described fitting seat 2 have the extending end 23 of fixed screw holes, and extending end 23 is symmetrical with central axis.In described fitting seat, teeth 22 are positioned on the inwall of one of them extending end 23, and another extending end inwall is without interior teeth.
During unlatching, the gear 1 of damper is by external force, and be with dynamic damping main body 3 entirety to be close to fitting seat 2 inner ring without interior teeth side by rotor shaft 6, now damping main body 3 dallies in fitting seat 2, does not stress, as shown in Figure 4,5.During reset, the stressed fitting seat 2 that is close to of damper has interior teeth side, and the outer teeth 71 of damping main body engage with teeth in fitting seat 22, thus damping main body 3 is started working, and realizes damping buffering.Have employed independently fitting seat structure, structure is very simple, utilizes teeth meshing engagement structure open between fitting seat 2 and damping main body 3, is easy to realize, production can reduces cost of production, can be mass-produced.
The above, it is only better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solutions of the utility model.
