Abstract
A buffer device of furniture comprises a cylinder body and an oil cylinder outer cover capable of sealing the cylinder body, wherein the oil cylinder outer cover is connected with a connection rod which is capable of sliding back and forth, one end of the connection rod extends into the cylinder body and is connected with a buffer piston, the other end of the connection rod extends out of the oil cylinder outer cover, the buffer piston is connected with the tail end of the connection rod extending into the cylinder body through an inner hole, the radical size at two ends of the buffer piston is larger than that of the middle section, the length of the middle section of the buffer piston is 2-5 mm, the side wall of the buffer piston is provided with a quincunx-shaped or gear-shaped notch, a gap is formed between the notch and the inner wall of the cylinder body, and an O-shaped sealing ring is sleeved outside the middle section of the buffer piston in a sliding mode and is capable of sealing the gap. When the buffer piston moves back and forth inside the cylinder body, the buffer piston and the O-shaped sealing ring have two different states inside the cylinder body, the flow quantity of silicone oil can be lowered when the buffer piston is closed, so that the buffer effect when the furniture is closed is achieved, and the low quantity of silicone oil can be increased when the buffer piston is opened, so that the opening movement of the furniture can be finished smoothly.
Description
Technical field
The utility model relates to a kind of buffer unit of furniture, specifically can be used for the buffer unit on drawer sliding rail or the switch hinge.
Background technology
In the connecting means for furniture of drawer sliding rail or switch hinge etc., all can be provided with buffer unit at present, make furniture when closing motion, obtain certain buffering, avoid impulsive force to damage furniture, also make its closing motion quieter.A kind of guiding rail buffering mechanism was disclosed on October 27th, 2004 such as Chinese patent literature CN2650617, be installed on the orbit determination of guide rail, in mating connection with the catch that is fixed on the moving rail, comprise oil cylinder cover, oil cylinder spring, piston, piston rod, described oil cylinder spring and piston are arranged in the oil cylinder cover, oil cylinder spring one end apical grafting is inboard at the oil cylinder cover, and other end apical grafting is on piston, and described piston is connected with the piston rod that passes the oil cylinder cover.This buffer unit cost of manufacture is higher, and the necessary spring that relies on of its buffering, causes its internal structure comparatively complicated.Therefore, require further improvement.
The utility model content
The purpose of this utility model aim to provide a kind of simple in structure, reasonable in design, cost of manufacture is low, the buffer unit of the furniture of good buffer effect, to overcome weak point of the prior art.
Press the buffer unit of a kind of furniture of this purpose design, comprise cylinder body, and the oil cylinder enclosing cover of salable cylinder body, its architectural feature is that oil cylinder covers outward and is connected with the connecting rod that can come and go slip, connecting rod one end puts in the cylinder body, and is connected with damper piston, and the other end of connecting rod stretches out the oil cylinder enclosing cover.
Described damper piston is connected to the end that connecting rod puts in cylinder body by its endoporus, and the radial dimension at damper piston two ends is greater than the radial dimension in its stage casing.
The length in described damper piston stage casing is 2-5mm.
Described damper piston sidewall is provided with the breach that is plum blossom-shaped or gear-like, forms the space between breach and the inboard wall of cylinder block, and damper piston stage casing sliding sleeve has the O-ring seals in salable described space.
Also be provided with oil-through hole on the described damper piston.
The end that described connecting rod stretches out cylinder body also is provided with connecting ball head.
Be full of silicone oil in the described cylinder body.
By adopting technique scheme, the end that connecting rod of the present utility model puts in cylinder body is provided with stopper, and is provided with damper piston on the connecting rod, has distance and sliding sleeve that O-ring seals is arranged between stopper and the damper piston.When damper piston moves back and forth in cylinder body, damper piston, O-ring seals have two kinds of different states in cylinder body, damper piston can reduce the amount of flow of silicone oil when closing, thereby reach the buffering effect of furniture when closing motion, damper piston can increase the amount of flow of silicone oil when opening, thereby makes furniture can finish swimmingly opening action.It has simple in structure, reasonable in design, cost of manufacture is low, the characteristics of good buffer effect, can be widely used on all kinds of drawer sliding rails or the switch hinge.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Figure 10, the buffer unit of this furniture comprises cylinder body 1, with the oil cylinder enclosing cover 5 of salable cylinder body 1, be connected with the connecting rod 4 that can come and go slip on its cylinder enclosing cover 5, connecting rod 4 one ends put in the cylinder body 1, and being connected with damper piston 3, connecting rod 4 other ends stretch out oil cylinder enclosing cover 5.The end that connecting rod 4 stretches out cylinder body 1 also is provided with connecting ball head 6.Be full of silicone oil 7 in the cylinder body 1.Connecting rod 4 is draw point, and intensity is larger, can satisfy instructions for use.
Referring to Fig. 8, Fig. 9, when furniture is closed (when drawer or hinge etc. are closed), damper piston 3 inwardly advances, and its direction of propulsion as shown in Figure 8.At this moment, silicone oil 7 pressurizeds on damper piston 3 right sides, thereby drive O RunddichtringO 2 to left movement and seal up damper piston 3 and cylinder body 1 inwall between the space, cause the silicone oil 7 on damper piston 3 right sides can only flow to by the oil-through hole 3.1 on the damper piston 3 left side of damper piston 3, as shown in Figure 9.Because these oil-through hole 7 apertures (present embodiment oil-through hole 7 apertures are 0.8 millimeter) are less, cause the flowing velocity of silicone oil 7 slower, make damper piston 3 obtain the effect of buffering, simultaneously, furniture is closed (being that drawer or hinge etc. are closed) and is slowed down, and buffering effect is remarkable.
Referring to Figure 10, when furniture is opened (when drawer or hinge etc. are opened), damper piston 3 pulls out, and its pull-out direction as shown in figure 10.At this moment, silicone oil 7 pressurizeds in damper piston 3 left sides, thereby driving O RunddichtringO 2 moves right, space between damper piston 3 and cylinder body 1 inwall is got through, greatly increased silicone oil 7 flows to damper piston 3 right sides from damper piston 3 left sides speed, more smooth and easy when damper piston 3 is pulled out, simultaneously, it is also smooth and easy that furniture is closed (being that drawer or hinge etc. are closed), do not have sluggish sense.
