Description
Technical Field
The utility model relates to a novel slide rail pull-out closing clamping point positioning device, in particular to a damping slide rail limited by a positioner.
Background
Drawer type slide rail on the existing market adopts plastic part stuck point location, low quality, and wear resistance is poor, and location pull-out and closing force value are unstable, and the locate function easily became invalid, occupation space.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a novel positioning device for a pull-out closing clamping point of a sliding rail, which adopts the clamping point positioning of an elastic sheet and utilizes a method of complementation of the mechanical principle of a stainless steel elastic sheet to prevent a sliding rail from pulling out a loose core, thereby prolonging the wear-resisting service life and ensuring that the pull-out and closing force values of a drawer sliding rail are more stable and durable.
The technical scheme of the utility model is that the positioning device is characterized by being arranged in the middle of one end in the outer rail, two sides of one end of the positioning device respectively extend forwards to form an elastic clip, the top of the other end of the positioning device is provided with a step bayonet, the front ends of the elastic clips are respectively bent and protruded outwards in an arc shape, and positioning convex blocks are respectively protruded inwards at the positions, corresponding to the elastic clips, of two ends of the inner rail.
The locator is integrally formed by metal through stamping.
The working principle of the utility model is that a metal integrally formed locator with a spring plate is fixed in the middle of one end head in an outer rail, the front end of the spring plate is bent in a sine wave shape and corresponds to the positions of locating lugs at two ends of the inner rail, when the locating lugs at the front end of the inner rail slide to meet the outer convex positions of the spring plate, the locating lugs force the spring plate to contract inwards, when the locating lugs at the front end slide over the rear spring plate and reset until the tail end of the inner rail is clamped to a stepped bayonet of the locator, the locating lugs at the tail end of the inner rail just fall on the inner concave section of the sine wave section of the spring plate, and the effect of clamping the inner rail is achieved.
The utility model has the advantages that product space utilization is high, the high quality, through the resistant tired characteristics of stainless steel shell fragment, improves the wearability, and the location is pulled out and the closure force value is more stable through the resistant tired characteristics of shell fragment, and control is accurate, can realize pulling out and close the high-efficient orderly circulation of more effective location.

fig. 3 is a schematic diagram of the structure of the utility model after sliding.
Detailed Description
According to the drawings of fig. 1, 2 and 3, the utility model is provided with an outer rail 1, an inner rail 2, a guide rail frame 3 and steel balls 4, wherein the guide rail 3 is arranged on a slide rail in the outer rail through the steel balls 4, the utility model is characterized in that the utility model is provided with a positioner 5, the positioner 5 is arranged in the middle of the inner right end of the outer rail 1, both sides of the front end of the positioner 5 respectively extend forwards to form elastic clips, the top of the rear end is provided with a step bayonet, the front end of the elastic clips respectively protrude outwards in a wave type arc bending way, both ends of the inner rail respectively protrude inwards at positions corresponding to the elastic clips to form positioning lugs 6, and the positioner is integrally formed by metal punching.
The utility model is an upgrade and innovation of the current unstable modes of various plastic installation, and overcomes the defect that plastic parts are not wear-resistant; the defects of unstable push-pull force value caused by unstable hardness and different surface smoothness of the plastic part are overcome; the defect that the positioning device is arranged in a narrow space on a shorter slide rail is overcome; the advantage of fatigue resistance of the stainless steel elastic sheet is developed; the advantage of simultaneous performance is developed.
Based on the difference, the slide rail is firstly pulled out to close the positioning clamping point device to be fundamentally transformed:
firstly, the clamping point positioner is made of a plastic material, is changed into a stainless steel material through punch forming, and the sliding rail can be ensured to be pulled out and closed to play a positioning role by generating a friction value with the clamping point at the position where the sliding rail is pulled out and closed.
And secondly, the inner surface of the outer rail of the sliding rail is fixed in a rivet riveting mode, so that the stability is improved, and the accuracy of the center line riveted on the inner surface of the outer rail of the sliding rail is improved by positioning two salient points on the inner surface of the outer rail and two holes on the spring plate clamping point positioner.
Thirdly, because the product draws the characteristic of overlength, use the curved tail of inner rail of plastic locator slide rail to need to hook and be used for guaranteeing to draw length on the slide rail pearl frame, because plastic positioner occupation space, the curved tail of inner rail can only hook slide rail pearl frame a little part, the risk of inefficacy has been increased, change into stainless steel shell fragment locator, can pass through in slide rail pearl frame bottom through stamping forming, the curved tail of inner rail of slide rail hooks on stainless steel shell fragment, stainless steel shell fragment intensity is obviously higher than pearl frame intensity, it is secure to draw intensity, greatly reduced the risk of inefficacy.
Fourthly, changing the plastic rubber of the positioner into a stainless steel elastic sheet; the plastic clamping point positioning device can be because of the temperature, hardness, the wearability, smooth finish and surface oil stain cause and slide rail inner rail clamping point between the frictional force value unstable, the tolerance is great, the risk of inefficacy is great, shell fragment clamping point positioning device obtains guaranteeing through the punching press size, because shell fragment positioning device size, the material is easily managed and controlled, the quality to promoting, frictional force leans on stainless steel shell fragment elastic control between the rail clamping point in the slide rail, fatigue resistance and wearability are strong, change the assurance, no inefficacy risk.
Fifthly, the plastic material has poor wear resistance, and the clipping point positioner will wear differently due to the adjustment of the clipping point height on both sides of the inner rail of the slide rail, resulting in unstable pulling-out and closing force values of the slide rail. The elastic sheet clamping point positioning device is easy to adjust the pulling-out and closing force values of the inner rail of the slide rail, the friction force value can be controlled by adjusting the heights of the clamping points at the two sides of the inner rail of the slide rail, the abrasion resistance is strong, the adjusted force value is stable,
sixthly, secondly, the shell fragment stuck point locator is because the material is thin, and the characteristics that intensity is high are changeed and are processed into less accessory, utilizes rivet fixed mounting at the outer rail internal surface of slide rail through the narrow and small space of slide rail pearl frame, plays stable positioning effect.
And finally, the elastic sheet clamping point positioner is convenient to mount, easy to process, capable of being used in different positions, easy to adjust the force value, strong in fatigue resistance, stable and accurate in control, and can meet the requirements of different force values through adjustment.
