Detailed Description
According to the utility model, as shown in fig. 1, fig. 2, fig. 3, fig. 4 and fig. 5, the utility model is characterized in that a lower outer rail 1, an upper outer rail 2, a rubber plug 3, a cylindrical worm nail 4, a rubber joint 5, steel balls 6, an upper inner rail 7, a lower inner rail 8 and a guide rail frame 9 are sequentially superposed from top to bottom and are connected and installed by matching the guide rail frame 9 with the steel balls 6, the rubber joint 5 is fixedly installed at the left end of the lower outer rail 1, and the top of the rubber joint 5 is provided with an inward arch bridge-shaped bayonet; the cylindrical worm nail 4 is arranged in the middle of the left end of the upper outer rail 2 and protrudes towards the inner part of the upper outer rail 2, the position of the cylindrical worm nail is opposite to that of the arch bridge-shaped bayonet of the rubber joint 5, the rubber plug 3 is sleeved on the cylindrical worm nail, and the rubber plug 3 can be forced to be pulled out or pushed in from the arch bridge-shaped bayonet of the rubber joint when the upper outer rail 2 slides back and forth towards the direction of the rubber joint 5. The rubber joint 5 is formed by plastic through integral injection molding, and an arch bridge-shaped bayonet of the rubber joint 5 is a bayonet which is wide in the inner part and narrow in the outer part and has elasticity.
The utility model is an upgrade and innovation of the current various plastic installation and use function modes, and overcomes the defects of single noise reduction and single positioning function of plastic parts; the defects of manufacturing difficulty and function simplification are reduced; the product integration is realized by utilizing the elasticity and the toughness of the plastic and adopting the advantages of the arch bridge and the gourd-shaped opening design, the functions are diversified, the manufacturing simplification is met, and the production efficiency can be improved.
Based on the difference, the utility model firstly makes fundamental improvement on the slide rail closing and positioning device and the noise reduction device:
firstly, rubber joint 5 adopts trilateral mounting means, and 5 section trompils suits of rubber joint are on the curved tail of slide rail outer rail, and rubber joint 5 adopts the anastomotic strengthening rib design with inside and outside rail both sides track, block in inside and outside both sides track, and trilateral location installation makes the installation of rubber joint 5 more firm, more stable.
Second, with traditional positioner by original single plastic part and slide rail inner rail both sides between the stuck point friction production draw power value location, play the positioning action, change into the new design positioner who adopts 5 calabash mouths of rubber joint, at last outer rail inner rail tail end riveted cylinder worm nail, when the slide rail is closed, slide rail inner rail worm nail card is gone into in the plastic part calabash mouth, parcel cylinder worm nail 3/4 surface, in addition there is the fretwork design rubber joint 5 calabash mouth both sides, increase plastic elasticity, make the power value more stable between worm nail and the rubber joint 5, can adjust the location again through adjusting the worm nail diameter and draw the power value size.
Thirdly, through utilizing plastic elasticity and toughness, the arch bridge shape is designed to 5 striking faces of rubber joint, when making the slide rail inner rail closed, the curved tail of inner rail strikes the arch bridge and plays the cushioning effect, has solved the false problem of rocking of closing back imaginary, adopts big fretwork design at the arch bridge back again, and the cushioning effect makes the slide rail slide closed speed reduction, and the arch bridge design of big fretwork at the back can play the noise and give off the effect again, plays striking noise reduction effect together.
Fourth, through redesign, rubber joint 5 installation originally should have two kinds of functional requirements that two kinds of mounting means and two kinds of accessories could be accomplished, and the present unified design realizes on a plastic accessory for two kinds of functions of positioning force value location and noise reduction to can be better promote its function, more stabilize the lifting quality. The perfect adaptation of two kinds of functions is accomplished to accessory, and 5 calabash mouths of rubber joint have played slide rail location power value stability effect with the design of slide rail inner rail cylinder snail nail, and the closed striking buffering of slide rail, greatly reduced noise effect have been played in the design of 5 arched bridges of rubber joint.
Finally, two functions of positioning and noise reduction and two single installation modes are designed into a whole, so that the working procedures are reduced, the production efficiency is improved, the two functions can be perfectly combined, the product quality is improved, and the product stability is improved.
