Cushioning device fitting for furniture

Abstract

The invention relates to a cushioning device fitting for furniture. The cushioning device fitting comprises a sway block which is slidably arranged in a sliding seatr through a spring and a touch part which is connected with the sway block by collision claspng, wherein the sway block is provided with a positioning buckle, the sliding seat is provided with a buckle position corresponding to the positioning buckle; a damper is arranged behind the sway block, the piston rod of the damper extends towards the sway block, the sway block is provided with a touch end surface corresponding to the end part of the piston rod, one end of the spring is connected with the sliding seat, and the other end is connected with the sway block by a sliding block; the sliding block is slidably arranged in the sliding seat and rotatably connected with the sway block; and the end part of the piston rod is provided with a cushion head, the sliding block is provided with a clamp block corresponding to the cushion head, and the clamp block is positioned behind the cushion head. The sway block is rotatably connected with the sliding block, and the sliding block is connected with one end of the spring, therebyavoiding the bending of the spring during the deflection of the sway block, and improving the operational smoothness degeree of the sway block. In addition, because the sliding block is provided withthe clamp block corresponding to the back side of the cushion head, the sliding block can drive the clamp block to move forward when the sway block sways out; and because the clamp block and the cushion head are blocked by each other, the piston rod can be effectively drawn to be in place synchronously.

Description

technical field [0001] The invention relates to a buffer device accessory, in particular to a buffer device accessory for furniture suitable for drawers, drawer slide rails, sliding doors and windows and the like. Background technique [0002] see figure 1 , figure 2 , are schematic structural diagrams of buffer device accessories in the prior art, including pendulum blocks 13, 13' slidably arranged in sliding seats 11, 11' through tension springs 12, and contact pieces that collide with the pendulum blocks and snap into contact 16. The pendulum block is provided with a positioning buckle, and the sliding seat is provided with a buckle corresponding to the positioning buckle, and the buckle is engaged with the positioning buckle of the deflected pendulum block; a damper 14 is also provided behind the pendulum block. The sliding seat and the touch piece are respectively arranged on the relative moving parts. The parts include stationary parts and movable parts. The station...

Problems solved by technology

Since the pendulum block and one end of the tension spring are fixedly connected, when the pendulum block deflects (after the deflection, the pendulum block is positioned by its positioning buckle and the buckle of the slide seat), the tension spring that was originally stretched in a straight line is also bent. (See figure 1 Middle A), which affects the smoothness of the pendulum block when it deflects and slides; at the same time, on the one hand, because the joint between the pendulum block and the front end of the piston rod is hinged through the opening slot (see figure 1 A' of the pendulum block), it is easy to separate the pendulum block from the piston rod when the pendulum block is pulled out or deflected, causing the pendulum block to fail to pull the piston rod out in place; Part of the component force that separates the positioning buckle of the pendulum block from the buckle of the slide seat makes the pendulum block (when the drawer is still in the open state) easy to automatically return to the state when the drawer is closed without collision with the contact parts, and causes damping The piston rod 15 of the drawer retracts into the damper, and when the drawer needs to be closed, the damper loses its buffering effect

[0004] in addition, figure 2 The middle damper is a piston rod automatic reset type damper, and assuming that the above-mentioned buffer device accessories are installed in the drawer slide rail, when the fast drawer is pulled out, the pendulum block 13' will be in place quickly, and the piston rod of the damper is not in contact with the pendulum block. Therefore, it often occurs that the pendulum block is in place, but the piston rod does not automatically extend out; or, when the damper is used for a long time, due to some unavoidable factors, the speed of automatic extension of the piston rod is relatively slow (much slower than the pull-out speed of the drawer under normal circumstances), and even, the piston rod cannot be automatically stretched out in place at all, so that when the drawer is closed again, the buffering effect of the damper is not significant
