A kind of cabinet door buffer structure
Technical field
The present invention relates to a kind of cabinet door buffer structure, be particularly useful for the cabinet door moving up and down switch, belong to door hinge construction applications.
Background technology
In the prior art, the cabinet gate open moving up and down switch often adopts the linkages such as hinge to be connected in cabinet main body.Such cabinet door be pulled outwardly open time, both hands must keep buttressing cabinet door, otherwise cabinet door just may impinge upon on wall or other platform, send huge noise, also can reduce the life-span of cabinet door, under upwards pushing away and closing state that cabinet door or cabinet door be in closedown, due to non-locking or the reason such as not fasten simultaneously, cabinet door is likely landing and opening also, can cause above-mentioned consequence equally.
Summary of the invention
In order to solve the problems of the prior art, make cabinet door use reliable, the life-span is long, the invention provides a kind of cabinet door buffer structure, for cabinet door is connected to cabinet main body.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cabinet door buffer structure, for connecting cabinet door and cabinet, described cabinet door buffer structure comprises the pawl base be fastenedly connected with cabinet door and the holder be fastenedly connected with cabinet, described pawl base is provided with a groove, the lug of pawl base and holder is provided with circular hole, and one has the ratchet of spring to be positioned in described groove at end cover, a ratchet and described click-fit, described ratchet also has circular hole, and a rotating shaft is inserted in the circular hole of pawl base, holder, ratchet also fixing.
Wherein, described pawl base, ratchet, ratchet, holder are at least one.
Preferably, described pawl base, ratchet, ratchet, holder are one.
Further, rotating shaft insert pawl base, holder, ratchet circular hole in and fixed by cottor pin at the two ends of rotating shaft.
Preferably, described pawl base, ratchet, ratchet, holder use all in pairs.
Preferably, described rotating shaft is multidiameter, to insert in the circular hole of pawl base, ratchet, holder and to be fixed between two pawl bases, and the length that pawl base is given prominence at the two ends of described multidiameter is sufficient to extend through the circular hole on ratchet, holder.
Preferably, described rotating shaft is multidiameter, and inserting in the circular hole of pawl base, ratchet and to be fixed between two pawl bases, and the length that pawl base is given prominence at the two ends of described multidiameter can only flush with the circular hole of ratchet at most.
Further, described holder is outstanding circular hole, described ratchet is also provided with the counterbore coordinated with the outstanding circular hole of described holder.
Further, damping grease is coated with between the counterbore of ratchet and the outstanding hole of holder.
The invention has the beneficial effects as follows: when using external force to pull cabinet door downwards, unidirectionally between ratchet with ratchet coordinate, under the effect of damping grease, ratchet is stuck on ratchet, and slowly rotates decline centered by rotating shaft, and drops on reposefully on platform; When using external force upwards to pull cabinet door, ratchet imposes reaction force to ratchet makes ratchet retract in pawl base, can be shut by cabinet door like a cork.After pulling out, cabinet door slowly lands, and the noise sent when reducing cabinet door contact wall or other platform, also extends the application life of cabinet door simultaneously, and after pulling, does not with the hands keep buttressing cabinet door; After upwards pulling, cabinet door can be pulled effortlessly to close, the impact of damping grease can not be subject to; When to pull way in, hand decontrol cabinet behind the door, ratchet can block ratchet, and cabinet door slowly can rotate decline, and can not decline fast and clashes into generation huge noise.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Figure 1 shows that the schematic diagram of an embodiment according to cabinet door buffer structure of the present invention;
Figure 2 shows that the exploded perspective view of embodiment shown in Fig. 1;
Fig. 3 A-3C is depicted as the process schematic opening cabinet door.
Detailed description of the invention
See figures.1.and.2, be an embodiment of cabinet door buffer structure of the present invention, wherein Figure 1 shows that the closed condition of cabinet door.
In the present embodiment, described cabinet door buffer structure comprises the pawl base 2 be fastenedly connected with cabinet door 1 and the holder 7 be fastenedly connected with cabinet, described pawl base 2 is provided with a groove, the lug of pawl base 2 and holder 7 is provided with circular hole, and one has the ratchet 4 of spring 3 to be positioned in described groove at end cover.One ratchet coordinates with described ratchet 4, and described ratchet also has circular hole, and a rotating shaft 5 is inserted in the circular hole of pawl base 2, holder 7, ratchet also fixing.
As the improvement to above-described embodiment, described pawl base 2, ratchet 4, ratchet 6,8, holder 7 uses all in pairs.
As the further improvement to above-described embodiment, described rotating shaft 5 is multidiameter, insert pawl base 2, ratchet 6,8, be fixed between two pawl bases 2 in the circular hole of holder 7, and the length that pawl base 2 is given prominence at the two ends of described multidiameter be sufficient to extend through ratchet 6,8, circular hole on holder 7.
In another preferred embodiment, described rotating shaft 5 is multidiameter, and inserting in the circular hole of pawl base 2, ratchet 6,8 and to be fixed between two pawl bases 2, and the length that pawl base 2 is given prominence at the two ends of described multidiameter can only flush with the circular hole of ratchet 6,8 at most.
As the improvement to above-described embodiment, described holder 7 is outstanding circular hole, described ratchet 6,8 is also provided with the counterbore coordinated with the outstanding circular hole of described holder 7.
In another preferred embodiment, described pawl base 2, ratchet 4, ratchet 6,8, holder 7 is one.
As the improvement to above-described embodiment, rotating shaft 5 to be inserted in the circular hole of pawl base 2, holder 7, ratchet 6,8 and is fixed by cottor pin at the two ends of rotating shaft 5.
As the further improvement to above-described embodiment, between the counterbore of ratchet 6,8 and the hole of the outstanding of holder 7, be coated with damping grease.
As shown in figs. 3 a-3 c, for opening the process of cabinet door, the flute profile of ratchet and ratchet can be designed to, and in this process, because ratchet coordinates with the unidirectional of ratchet, ratchet is stuck on ratchet and produces braking action, and slowly rotate decline centered by rotating shaft; In like manner, in the process of closing cabinet door, ratchet imposes reaction force to ratchet makes ratchet retract in pawl base, can be shut by cabinet door like a cork.
The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should fall within protection scope of the present invention.
