Abstract

The utility model relates to a guide rail, which comprises an external rail, an internal rail and a buffer which is installed on the external rail and connected with the internal rail. The buffer comprises an internal frame and an external frame which is provided with a guiding groove,and the internal frame is correspondingly provided with a guiding rod capable of sliding inside the guiding groove. Two springs which are capable of enabling the guide rail to enter horizontally and a damper are installed between the internal frame and the external frame. Compared with the prior art, the buffer of the guide rail is simple in structure, low in cost, and good in buffering effect. Meanwhile, the tension of the two springs is even, therefore, the two springs can be fully pulled out when installed on the guide rail. Louder impact sounds do not occur when drawers are opened by pull and closed. The service life of the guide rail and furniture can be effectively prolonged.

Description

A kind of guide rail

Technical field

The utility model relates to a kind of furniture part, particularly a kind of guide rail.

Background technology

Existing each all use guide rail with furniture or office furniture or kitchen appliance major part, employed guide rail comprises outer rail, interior rail and buffer; Buffer is installed on the outer rail and with interior rail and is connected, above-mentioned buffer be single spring, cushion stroke short, be installed on the slide rail can not pull out entirely, mounted component is many, the complex structure cost high and cushion the shortcoming of poor effect.

The utility model content

The utility model is intended to solve the above-mentioned defective of prior art, provide a kind of simple in structure, cost is low and the guide rail of good buffer effect.

The technical scheme that the utility model adopted is: a kind of guide rail; Comprise outer rail, interior rail and buffer; Buffer is installed on the outer rail and with interior rail and is connected, and said buffer is made up of internal frame and outrigger, and outrigger is provided with a guide groove; The corresponding guide rod that can in guide groove, slide that is provided with of internal frame is equipped with two and can makes guide rail flat to the spring and the damper that get between internal frame and the outrigger.

Said outrigger both sides are provided with the cavity that holds spring, and spring one end is connected with internal frame, and the other end is connected with outrigger.

Said spring is two extension springs.

Be provided with the empty chamber that holds damper in the said outrigger, the damper upper end is fixedly connected with internal frame, presents an integral body after installing.

Rail one end is provided with a breach and through hole in said, and a clamping block is installed on breach and the through hole.

Said guide rod is provided with one and connects slide block.

Said connection slide block is processed by kirsite.

Said internal frame upper end is provided with two serpentine legs, plays the crashproof effect of eliminating the noise.

Compared with prior art; That the utility model guide rail buffer has is simple in structure, cost is low, good buffer effect and two spring tensions are even; Be installed on the guide rail and can pull out entirely, when drawing back, can effectively not prolong the service life of guide rail and furniture because of sending bigger impact sound with closing drawers.

Description of drawings

Fig. 1 is that the utility model is the stereogram of guide rail;

Fig. 2 is the exploded view of buffer.

The specific embodiment

Like Fig. 1, shown in Figure 2: a kind of guide rail of the utility model, comprise outer rail 1, interior rail 2 and buffer 3, buffer 3 is installed on the outer rail 1 and with interior rail 2 and is connected; Buffer 3 is made up of internal frame 31 and outrigger 32; Outrigger 32 is provided with a guide groove 321, and the internal frame 31 corresponding guide rods 311 that can in guide groove 321, slide that are provided with are equipped with spring 4 and damper 5 between internal frame 31 and the outrigger 32; Spring 4 is used to make interior rail 2 to reset and makes guide rail flat to entering; Buffering when rail 2 resetted in damper 5 was used for can effectively not prolong the service life of guide rail and furniture because of sending bigger impact sound when drawing back with closing drawers.

Outrigger 32 both sides are provided with the cavity 322 that holds elastic component 4, and cavity 322 is roughly L-shaped; Spring 4 one ends are connected with internal frame 31, and the other end is connected with outrigger 32, and spring 4 is two extension springs; Rail 2 slip ratios were mild in two extension springs made, the life-span is long; Two extension springs are installed on the guide rail and can pull out entirely, such as: the guide rail that 300MM is long, length is pulled out in two extension springs can reach 300MM.Be provided with the empty chamber 323 that holds damper 5 in the outrigger 32, damper 5 upper ends are fixedly connected with internal frame 31, present an integral body after installing.

Interior rail 2 one ends are provided with a breach 21 and are installed on breach 21 and the through hole 22 with through hole 22, one clamping blocks 6.Guide rod 311 is provided with one and connects slide block 7, connects slide block 7 and is processed by kirsite.Internal frame 31 upper ends are provided with two serpentine legs, 312, two serpentine legs 312 and play the crashproof effect of eliminating the noise.
