Description

A full-extension drawer slide rail limit assembly

technical field

The utility model relates to a drawer slide rail, in particular to a full-extension drawer slide rail limit assembly.

Background technique

There are two types of drawer installations at present. One is to directly slide and frictionally push the drawer frame into the cabinet or table. The drawer and the frame rub against each other during the process of pulling, pushing, and opening. It is used in a large area office, which has higher requirements for drawer materials, and the drawer will tilt after being pulled out, which is not conducive to the neat placement of items; the other is to install slide rails and drawer frames on both sides of the drawer, and the drawer can be It is stable and does not tilt and has low noise, low friction and less wear.

The slide rail drawer has a simple form, which slides and can be taken out by overlapping the wheels and rails, but its thin and fragile structure is not durable. So there is a slide rail drawer with a more stable structure and two slide rails that slide each other. However, the two slide rails of this kind of drawer cannot be completely staggered, and the drawer box cannot be fully pulled out, that is, the drawer cannot be fully expanded. There are difficulties in storing items, and the only way to shorten the drawer box is to give up a certain space. Then there is a slide rail structure using three rails, which can make full use of the space. Later, a two-and-a-half-section slide rail appeared, which welded and fixed a half-section auxiliary rail at the inner end of the surface rail, so that the drawer could be fully extended in a horizontal and stable state, making it easy to pick and place items.

No matter what kind of track needs to be braked at the final limit position after the drawer is pulled out, the current brake parts use two parts in contact, and when they touch, they are cushioned by the elasticity of the material itself, or by rigid collision Implement braking.

As an improvement of the technical solution of the full-extension drawer slide rail limit assembly of the utility model, the stretching frame is in the shape of a sun.

As an improvement of the technical solution of the full-extension drawer slide rail limiting assembly of the present invention, the coupling parts respectively connect the sides of the blocking part and the bottom of the mounting block.

The beneficial effect of the utility model is that the cladding shell can further slide for a certain distance on the basis of the surface rail sliding, so that the drawer can be fully unfolded, which is convenient for picking and placing items, and can also keep the drawer with the largest space and be stable and not tilted. The state of the item in full bloom. A stopper is set to hinder the brake arm so that it cannot pass over the stopper. The brake arm is used as a stopper, and the stopper and the stopper are mutually restricted to achieve pull-out braking, thereby stopping the relative sliding movement between the cladding shell and the surface rail. Make the drawer stop pulling out when it is fully extended, to prevent the drawer from sliding out and falling.

Detailed ways

The specific embodiment of the utility model will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 6, the utility model is a full-extension drawer slide rail limit assembly, the full-extension drawer slide rail includes a bottom rail 11 fixedly connected to the inner surface of the side panel of the cabinet body, which can be slidably installed on The surface rail 21 of the bottom rail, the roller slide support assembly 12 located between the bottom rail 11 and the surface rail 21, the cladding shell 31 that is buckled and covered on the top and both sides of the surface rail 21 and fixedly connected with the drawer box, the surface rail 21 is provided with a stopper 22 that is fixedly connected to the surface rail 21 and protrudes from the periphery of the surface rail 21. The middle part of the cladding shell 31 is provided with a brake that corresponds to the position of the stopper 22 and prevents the cladding shell 31 from sliding out excessively. arm33. The covering shell 31 can slide a certain distance further on the basis of the sliding of the surface rail 21, so that the drawer can be fully unfolded, which is convenient for picking and placing items, and can also keep the drawer with the largest space and a stable and non-tilting state for holding items. The stopper 22 is set to hinder the brake arm 33 so that it cannot cross the stopper 22, the brake arm 33 is used as a brake, and is mutually restricted with the stopper 22 to realize the braking of pulling out, so that the gap between the cladding shell 31 and the surface rail 21 Stop the relative sliding movement in between, so that the drawer stops being pulled out when it is fully extended, and prevents the drawer from sliding out and falling.

More preferably, the outer end of the covering shell 31 is provided with a crosspiece arm 32 corresponding to the position of the blocking member 22, and without the action of other linkage mechanism, the covering shell 31 is pushed synchronously when the drawer is retracted. In, the surface rail 21 can be driven back and retracted by the crosspiece arm 32. In the case that the cladding shell 31 is fully linked with the surface rail 21, the crosspiece arm 32 can be used as a brake for the return stroke to stop when the return stroke reaches the end point.

More preferably, the blocking member 22 includes a mounting block 25 for fixed connection with the surface rail 21, a coupling portion 26 inclined and deflected to form an introduction slope 23, U-shaped and jacketed inside and outside the wall plate of the surface rail 21 The blocking portion 28 on the side is swingable and can be pressed back, and the connecting portion 26 is integrally connected with the mounting block 25 and the blocking portion 28 respectively. The coupling part 26 has the effect of deformation and bending, so that the rear part of the blocking part 22 away from the mounting block 25, that is, the blocking part 28, can be pressed and deformed, so that the brake arm 33 can pass over the blocking part 22 to pull the cladding shell 31 away from the surface rail. Disassemble. The introduction slope 23 can facilitate the assembly of the cladding shell 31 and the surface rail 21 to guide the brake arm 33 over the stopper 22 , so as to facilitate the assembly of the new surface rail 21 and the cladding shell 31 .

More preferably, the coupling part 26 is provided with a transverse through hole so that the main body retains the connecting stem, making it easier to deform so as to facilitate the pushing of the blocking part 28 to change its position, remove the hindrance to the brake arm 33, and facilitate the smooth removal of the surface rail 21 and cladding shell 31.

More preferably, the connecting stems are in the shape of a sun, and the connecting stems are pulled together to maintain a stable shape, which is easy to achieve elastic deformation and quickly restore the shape.

More preferably, the blocking portion 28 is provided with a transverse elongated perforation so that it retains a stretcher, which acts as a deformation buffer when the brake arm 33 contacts it, absorbs shock and noise, and achieves buffering through structural elasticity.

More preferably, the stretching frame is in the shape of a sun, and the stretching frames are pulled together to maintain a stable shape, which is easy to achieve elastic deformation and quickly restore the shape.

More preferably, the coupling portion 26 is respectively connected to the side of the blocking portion 28 and the bottom of the mounting block, respectively connected to different parts so that its length can be extended so as to have sufficient elastic deformation space and elasticity, and can form an introduction slope 23 .

What is disclosed above is only the preferred embodiment of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, the equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
