Abstract

The utility model relates to a silencing and buffering device for a telescopic sliding rail, which is used in a mechanical sliding or pushing mechanism. The end of the scraping plate of a chip scraping device is provided with a scarf-joint groove which is connected with a silencing block in scarf joint. The side ends of the sliding box plates of the telescopic sliding rail which are mutually inserted are provided with silencing blocks to make the soft silencing blocks play a role in the buffer action to reduce noise when the actions of two opposite sliding box plates are mutually touched.

Description

Muffler buffer unit of expansion sliding rail

The utility model relates to a kind of noise reduction buffer unit that is used for the flexible slide rail of machinery slip or pushing mechanism, mainly be to be provided with scarfing slot and silencing block interlocking at the scraper plate end of scraping the bits device, slip boxboard inlay card side at flexible slide rail is embedded with silencing block, make two relative slip boxboards when start is touched mutually, play cushioning effect to reduce the noise that produces because of collision with soft silencing block.

General flexible slide rail as shown in Figure 6, it is in order to drive or to promote the device of other mechanisms in the mechanical device, mainly be just can stacked mutually slip boxboard 40 by multi-disc such as ㄇ font and size, 401,402 form, please cooperate three to see Fig. 6, shown in 7, second later slip boxboard 40 at flexible slide rail, 401 front end be provided with by scraper plate 60 and wiper sheet 70 form scrape bits device 1, this scraper plate 60 is in the stepped and solid welding folded mutually with a slip boxboard 40 of the square after a while one-tenth of front end, form dovetail groove 62 in scraper plate 60 lower ends, wiper sheet 70 is to form sphenoid in the front portion, the upper end then forms dovetail seat 71, wiper sheet 70 is matched with the dovetail groove 62 of scraper plate 60 with its dovetail seat 71, and the front end of wiper sheet 70 just pastes the below that is butted on scraper plate 60 front ends, then when two relative slip boxboards 40, when 401 past relatively superimposed directions advance, then the wiper sheet 70 of top slip boxboard 40 promoted to push remove slip boxboard 401 end faces residual chip, and when two slip boxboards 40, during 401 starts when relatively stretching, then promptly can touch mutually with scraper plate 60 ends 61 of the slip boxboard 40 on upper strata than the riser 41 of slip boxboard 401 ends of lower floor, and this one touches the generation source that is a kind of noise, and make easily to produce vibrations between this two impingement members, and reduce mechanism stability.

Because traditional slip boxboard is when action, sliding in twos has the situation of collision contact unavoidably between boxboard, so easily produce noise, can cause vibrations simultaneously, can lower the steadiness and the life-span of structure, the utility model designs on the slip boxboard has the noise reduction buffer unit to improve the shortcoming of traditional structure.

Main purpose of the present utility model is: the noise reduction buffer unit that a kind of flexible slide rail is provided, it is provided with scarfing slot and silencing block interlocking at the scraper plate end of scraping the bits device, slip boxboard inlay card side at flexible slide rail is embedded with silencing block, make two relative slip boxboards when start is touched mutually, play cushioning effect with soft silencing block, and reduce noise and vibrations.

The noise reduction buffer unit of the flexible slide rail that the utility model provides, it is characterized in that: the scraper plate rear below the slip boxboard is formed with the scarfing slot of several inverted T-shapeds, be provided with as I-shaped soft silencing block, then silencing block is forced in the scarfing slot with the one end and the other end forms convex shape to prevent to collide the noise of generation.

The riser that is formed with several scarfing slots of tool is protruded in the both sides of described slip boxboard end, compels to establish several silencing blocks on scarfing slot.

I-shaped body two ends of described silencing block can form different length.

Effect of the present utility model is: by the noise reduction buffer unit, make a plurality of silencing blocks play noise reduction and shockproof effect, can obtain the effect that reduces noise and slow down vibrations, and solved the shortcoming of similar traditional mechanism.

Further specify architectural feature of the present utility model and purpose below in conjunction with accompanying drawing.

Fig. 4 is embodiment of the present utility model (twos') a profile.

Fig. 5 is a part cutaway view of the present utility model.

Fig. 6 is the structure outside drawing of flexible slide rail.

Fig. 7 is traditional slide rail partial section view.

As shown in Figure 1, flexible slide rail of the present utility model is spliced by 40,401,402 of a plurality of slip boxboards and forms, slip boxboard 40,401 except foremost is provided with in front end and scrapes bits device 1, slip boxboard except rearmost end 401,402 tops in rear end, side are formed with riser 41 and fin 42 respectively again, wherein are formed with several scarfing slots 43 on riser 41 and the fin 42; Front end and another mechanism of slip boxboard 402 foremost join, and the end of the slip boxboard 40 of rearmost end then forms fixedly wing plate 44 to be fixed in a certain fixed point or another mechanism.

Scrape bits device 1 structure as shown in Figure 2, constituted by scraper plate 10, wiper sheet 30 and silencing block 20, please cooperate three to see shown in Fig. 2,3, scraper plate 10 forms a flight 11 in the top, just can hold the thickness of slip boxboard 40 and the two is mutually combined fixing in these flight 11 formed depressions, and its front end below forms brush film trap 13, below then be formed with dovetail groove 12; Be formed with the scarfing slot 14 of several inverted T-shapeds again endways.

Silencing block 20 forms as is I-shaped, and the length of its two end can be different slightly, and silencing block 20 stage casings can be embedded in the scarfing slot 14 by an end button.

Wiper sheet 30 is a soft brush body, and its upper end forms dovetail seat 31 can be matched with dovetail groove 12, its front end is just pasted be butted on brush film trap 13 places and have strike off chip 50(ask three see shown in Fig. 3) function.

Shown in Fig. 2,3,4, when a relative position is that the slip boxboard 401 of front end is when moving forward, 41 of the risers of its tail end forward with the slip boxboard 40 in the place ahead on the set silencing block 20 of scraper plate 10 tail ends collide, but because the setting of soft silencing block 20 is arranged, it has cushioning effect, can slow down noise and vibrations.

Shown in Fig. 1,5, because silencing block 21 also can be embedded on the scarfing slot 43 of fin 42, at two slip boxboards 40,401 relatively during action, all side flanges that this fin 42 that is provided with silencing block 21 touches another slip boxboard 40 also can form the cushioning effect of a noise reduction.
