Background technology
Unidirectional rotary semi-automatic door can be closed under the pulling of puller system after being opened by manpower automatically; Because the effect of kinetic energy, door can produce bump with the frame of door when closure; So before door is closed fully, must cushion and just can not produce bump to consume kinetic energy.The principle of existing snubber is: the rotary buffer that is contained in Men Dingchong; Snubber has buffer gear cold; When door slided to doorjamb fast, the gear on the snubber contacted with the tooth bar that places the doorframe top and produces resistance, reaches the purpose of the movement velocity that reduces door.Present snubber be owing to can not regulate cushion effect, but constantly regulates the length of buffering tooth bar and realize the position and can effectively close, and do not produce the effect of bump again, wastes time and energy.The utility model can effectively change this situation.
Existing semi-automatic door has part to adopt the rubber elastomer buffering, orthoscopic hydraulic cushion and several kinds of patterns of viscous rotary buffer buffering:
Rubber elastomer is owing to be the former device of a kind of accumulation of energy, and it can not close front reduction gear at door, is absorption portion energy when producing bump, and energy remaining can make a generation bounce-back.
The orthoscopic oil buffer must be provided with back-moving spring because buffer head need reset, and it can cause door to fit badly.
Common rotary buffer; Because the moment of torsion in the time of can not regulating buffering; Can only regulate the position and the length of buffering tooth bar, make when installing and can't control, it is too little to add the buffer gear cold diameter; The snubber rotating cycle too much generates heat, and oil viscosity descends and makes the reduction of buffering moment of torsion and make door when closing, produce bump.
The problem that existing technical scheme mainly exists is: less gear makes the snubber rotating cycle too many, and the snubber inner heat reduces oil viscosity during continuous action, and cushion effect descends, and the impulse force of door and cushion effect do not match and produce bump.
Therefore, prior art awaits to improve and development.

Fig. 3 is the end view of the snubber that provides of the utility model.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, clear and definite, below develop simultaneously embodiment to the utility model further explain with reference to accompanying drawing.
The utility model is a kind ofly to be used for semi-automatic door and door to be opened the buffer under the operating mode of closing automatically under the pulling of back door at puller system at manpower.Because door can produce impulse force when closing, want door and when closing, do not produce bump, just must take place before the bump its kinetic energy to be consumed in it and doorframe, the utility model produces based on this purpose.
Referring to Fig. 1,2 and 3, the snubber that the utility model provides comprises housing (1), end cap (2), gear (3), main damping wheel (4); Secondary damping wheel (5), rotating shaft (9), cut spring (15), adjustment screw (16); Adjusting nut (17), regulating piston (19), piston seal (20), end face meshing gear (21).
Said end cap (2) is full of full-bodied damping grease with hermetic cavity body of the fixing formation of 4 lock screws (22) and housing (1) in the cavity; The arranged outside of said end cap (2) has a bearing (11), and its inboard is provided with bearing seal (12), and said bearing seal (12) is provided with seal cover (14).The bearing (11) on the said end cap (2) is passed in said rotating shaft (9).For the sealing performance end cap that improves end cap (2) is provided with end cap seal part (13).
Be built in that main damping wheel (4) and secondary damping wheel (5) are set on respectively in the said rotating shaft (9) in the cavity, and be meshing with each other, obtain different moments of torsion through end face meshing gear (21).Between said main damping wheel (4) and secondary damping wheel (5), also be provided with cut spring (15), make main damping wheel (4) under only needing, keep separating than the situation of slight drag with secondary damping wheel (5).Main damping wheel and rotating shaft one-shot forming when injection moulding is an one.
Said secondary damping wheel (5) is provided with a regulating piston (19), changes chamber pressure through compression adjustment piston and obtains different moments of torsion.The utility model is through being provided with adjustment screw (16) in housing (1) bottom and adjusting nut (17) is used as regulating the pressure force of said regulating piston (19) to secondary damping wheel (5); Thereby play the engagement dynamics that increases between two damping gears, thereby obtain the moment of torsion of different sizes.In order to prevent between said regulating piston (19) and adjustment screw (16), to be provided with anti-abrasive disc (18) because long-term friction causes regulating piston (19) to damage between adjustment screw (16) and the regulating piston (19).In order to improve the sealing of regulating piston (19), on said regulating piston (19), also be provided with piston seal (20).
The bearing (11) that is arranged on the outside of said end cap (2) is provided with bearing cover (10), and it is last and chimeric with said bearing cover (10) that said gear (3) is set in rotating shaft (9).Littler for the friction that makes the rotation of gear (3) in rotating shaft (9), in said gear (3), be provided with unilateral bearing (6), the needle roller (7) of said unilateral bearing (6) rolls around said rotating shaft (9).Gear (3) is fixed in the rotating shaft (9) with jump ring (8).
This snubber is installed on the suspension arrangement of semi-automatic door, when door is opened or closes with door and move.Operating principle is:
Semi-automatic door normally is in closed condition; The gear of snubber (3) pushes up the terminal engagement of the buffering tooth bar that dashes with being loaded on doorframe, and when the door defendant opened, the unilateral bearing that dashes in the buffer gear cold (6) was in released state with rotating shaft (9); Buffer gear cold (3) idle running, rotating shaft (9) is motionless.Under the pulling of external force disappearance back door at puller system of opening the door, begin to reset; When running to buffer gear cold (3) and buffering tooth bar when contacting; The unilateral bearing that dashes in the buffer gear cold (6) locking rotating shaft (9) drives the rotating shaft rotation, and rotating shaft (9) drives main damping wheel (4) rotation; Main damping wheel (4) produces resistance under the effect of high-viscosity oil liquid, the movement velocity of door is reduced reach door slowly to close.
When door when closing and doorframe clash into, explain that the buffering moment of torsion of snubber is too small, as long as turn adjustment screw (16); Adjustment screw with regulating piston (5) to internal compression; The internal cavity increased pressure, the resistance that main damping wheel (4) produces increases, and continues turn adjustment screw (16); Regulating piston (19) compression cut spring (16) causes plane meshing gear (21) engagement between the major-minor damping wheel; When rotating shaft was rotated, the major-minor damping wheel rotated the bigger resistance of generation together, and the moment that rotating shaft (9) is exported becomes big.Reverse turn adjustment screw (16) then can produce a contrary effect.
The utility model is through adopting primary and secondary two damping wheels, and the engagement through two damping wheels is obtained different moments of torsion with separating; And thereby the snubber inner heat reduces oil viscosity when changing chamber pressure and obtain different moments of torsion and realize preventing continuous action through compression adjustment piston, and cushion effect descends, and the impulse force of door and cushion effect do not match and produce bump.The utility model has not only improved the life-span of snubber; Simplified the Installation and Debugging process; Also make the work of snubber more stable
Should be understood that; The application of the utility model is not limited to above-mentioned giving an example; Concerning those of ordinary skills, can improve or conversion according to above-mentioned explanation, all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims.
