Description

Sliding door buffering restorer with tripping reset function

Technical Field

The utility model relates to a hardware fitting specifically is a sliding door buffering restorer with dropout reset function.

Background

Generally, a large-sized sliding door is heavy, and therefore, when the sliding door starts to move, the door may collide with the door-closing side end portion with a large impact force due to the momentum of the sliding door. This condition may degrade the quality of the furniture. In order to prevent the collision state when the door is closed on the door closing side of the sliding door as described above, the momentum of the sliding door when it is closed is finally as weak as possible, which may cause the sliding door to be untimely closed. This is also the cause of the reduction in the quality of the furniture. So the last strand of push-and-pull door of current furniture has all used attenuator (buffer), and the shifting block of stirring the attenuator of installation in the last track of push-and-pull door, when promoting the push-and-pull door and leaning on the limit, the shifting block card is on the moving part of attenuator, drive the slow movement of push-and-pull door, until stopping at the frame next door of door, because the buffering reset action of attenuator, make the push-and-pull door can not bump when being close to the door frame, avoid sending the noise because of the collision, the protection push-and-pull door can not consequently and the collision damage even, consequently, enjoy consumers.

The basic structure of the 'sliding door buffer device' in the current market is basically that the 'sliding door buffer device' is provided with a support, a gas-liquid buffer cylinder is fixed on the support, a sliding block is connected with the telescopic rod end of the buffer cylinder, a shifting block for shifting the sliding block is arranged on a door frame, and a transverse pin is inserted in the sliding block. When the sliding door is opened, the shifting fork drives the sliding block guide groove to move and drives the buffer cylinder to extend out, the extending buffer cylinder has a returning driving force, and if the opened sliding door does not reach the self-locking position, the buffer cylinder drives the door frame to return to the closed state. Therefore, the buffer device needs to be provided with a self-locking mechanism, the front end of the guide groove is bent in an L shape, when the shifting fork brings the sliding block to the bent position of the L-shaped guide groove, the sliding block enters the self-locking guide groove deviated from the main guide groove, the sliding block is separated from the shifting fork, and after the sliding block is self-locked, the door frame can continue to move forwards. When the door is closed, the shifting fork takes the sliding block away from the self-locking guide groove, and the sliding block drags the door frame back to a closed state under the action of the cylinder. However, when the sliding block enters the self-locking guide groove, if the door frame is impacted or vibrated, the sliding block is easy to separate from the self-locking slideway for resetting when the door frame is not shifted by the shifting block, so that the shifting fork is separated from the sliding block, the door is not closed by the buffer and the automatic resetting, and meanwhile, the sliding door cannot be completely closed due to the limitation of the installation position. Therefore, the door frame needs to be disassembled and then reinstalled to be used, which is very inconvenient.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a sliding door buffering restorer with dropout reset function which characterized in that: the sliding type LED display panel comprises a main board 1 and a panel 2 which are mutually buckled, a lower panel 3 is clamped and fixed between the main board 1 and the panel 2, a guide groove 4 is formed in the lower panel 3, and a guide post is arranged on a sliding block 5 and is positioned in the guide groove 4 to slide; the panel 2 is provided with a clearance groove 21, a hanging needle 61 positioned on the shifting plate 6 passes through the clearance groove 21 to be hung and buckled or separated with an anti-disengaging hook 51 on the sliding block 5, a damping tube 7 and a reset tension spring 8 are arranged between the panel 2 and the sliding block 5, and the reset tension spring 8 always pulls the shifting block towards the door closing direction; the anti-disengaging hook 51 comprises a first supporting block 511 and a second supporting block 512 which are integrated with the shifting block, the first supporting block 511, the second supporting block 512 and the shifting block main body are distributed in a triangular shape, the free end of the second supporting block 512 is provided with an anti-disengaging block 513 which is buckled into a positioning groove 52 arranged on the slider 5 body for fixation, a hook area 54 is formed between the outer side of the second supporting block 512 and the accommodating groove 53 of the slider 5, and the hanging needle 61 is hung and buckled in the hook area 54.

The first supporting block 511, the second supporting block 512, the anti-dropping block 513 and the shifting block are integrally made of plastic materials.

The anti-falling block 513 and the second supporting block 512 are distributed in a T shape.

The first supporting block 511, the second supporting block 512 and the anti-dropping block 513 are suspended.

The guide groove 4 include the groove that resets 41 and the trip groove 42, reset groove 41 and mainboard 1 parallel arrangement, trip groove 42 is located the end of the groove 41 that resets, sets up towards the slope of the groove 41 lateral wall direction that resets, switches on through circular arc groove 43 between the groove 41 that resets and the trip groove 42.

The working principle is as follows: when the flat sliding door is installed, the buffer body can be installed on a doorframe of the flat sliding door, the shifting plate is installed in a guide rail of the doorframe, and when the buffer body is installed, the sliding block is required to be in a reset state, and the flat sliding door is in a closed state, and at this time, the hanging needle is hung and buckled in the hanging and buckling area 54 on the sliding block. When the door is opened, the door plate is opened outwards, the hanging needle is stressed on the anti-disengaging hook 51 of the sliding block, therefore, the sliding block is dragged to enter the disengaging groove from the resetting sliding groove, the front end of the swinging sliding block swings towards the side wall direction, the hanging needle is separated from the sliding block, and the door frame can be continuously opened.

When the door is closed, the door leaf moves towards the door frame, when the hanging needle collides with the sliding block, the sliding block is separated from the tripping groove, the hanging needle is hung with the anti-tripping hook again, and simultaneously, under the pulling of the spring in the buffer, the fixed sliding block drags the swinging sliding block to move towards the door frame, so that the door leaf is dragged to close, and the effect of buffering the door closing is achieved.

When the door frame is impacted and vibrated or other reasons cause the sliding block to break away from the tripping groove and return to the reset sliding groove, when the door is closed, a user pushes the hanging needle to be in contact with the first supporting block of the anti-tripping hook through the door leaf and pushes the hanging needle to swing inwards, and finally the hanging needle is hung and buckled with the anti-tripping hook again to restore the normal working state. During normal use, the needle is forced on the second supporting block 512, and the anti-drop block 513 plays a role in positioning the first and second supporting blocks, so that the needle can only deform in one direction.

Compared with the prior art, the utility model has the advantages of simple structure, low in production cost, long service life, the reliable operation can easily reset after the unexpected reseing of buffer slider, need not to dismantle door frame rerun installation buffering slider and stop the piece.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
