Description

Buffer

Technical field

This practical cupboard cabinet bucket that relates to pushes the returning device new varieties automatically.

Background technology

Existing cupboard cabinet bucket pushes returning device automatically and realizes with the single spring power of crispaturaing, when the cabinet bucket is extracted out, finger stretches the coil spring that is in the normal state, when being stretched to the limit, positioner is located the spring extended state, when the cabinet bucket is pushed into certain depth, finger is removed the spring positioning states, the spring power of crispaturaing just hauls finger rapidly and the cabinet bucket pushes return automatically, there is following drawback in this device: vibration and noise are big, and each connector is easily loosening, and it is unreliable to work, product is not durable, and product specification is low.

Summary of the invention

The purpose of this utility model is to provide a kind of can overcome the silk ribbon attached to an official seal or a medal of above-mentioned drawback towards device.

This device comprises oil cylinder group, joint, slide block, take-up housing and spring; The oil cylinder group comprises cylinder body, piston, piston rod; Cylinder body one side has U-lag, and an end has pipe joint, and piston is a valve shape, and it comprises valve body, flap and flap seat; Valve body has uniform axial hole, the valve body mesopore is equipped with piston rod, the valve body top is equipped with the flap seat, there is outward flange flap seat end, flap is a flange shape, be sleeved on flap seat outside, slide block top has U-shaped to dial hook, and a hook is arranged at the bottom, there is guide finger at two ends, the take-up housing joint is connected with the cylinder ends pipe joint, in the middle of the take-up housing cannelure is arranged, and there is gathering sill both sides, rearward end has hold-down hook, front end has mounting groove, and slide block is installed in the take-up housing cannelure, and the two ends guide finger is inserted in the take-up housing gathering sill, slide block is connected with joint with the piston rod end, spring is installed in the cylinder body U-lag, and an end is fixed in the bayonet socket of U-lag outer end, and the other end is fixed in the take-up housing hook, this device is installed on the cabinet bucket fixed guide, the take-up housing hold-down hook hooks on stomidium behind the fixed guide, and movable lug is pressed on the anterior mounting groove of take-up housing on the fixed guide, and oil cylinder group cylinder body is in the fixed guide rear portion.

Operation principle: when cupboard cabinet bucket is pulled out, shift fork falls in the slide block U-shaped hook, and the drive slipper piston moves ahead, when piston moves ahead, flap leaves valve body, open valve hole, the oil of cylinder body leading portion flows into the cylinder body back segment from the through hole non-resistance, and when slide block has arrived crook under the take-up housing guide groove, the slide block front portion is fallen in the bending guide groove, hook moves down before the slide block U-shaped hook, slide block is positioned in the there, and spring is in extended state, and this moment, piston was in cylinder body foremost, the accessible continuation of shift fork moves ahead, and the cabinet bucket is pulled out entirely; When the cabinet bucket was pushed certain depth, shift fork arrived the slide block place, and shift fork is set upright slide block, removed the location, and the spring power of crispaturaing just pushes full return to slide block, shift fork and cabinet bucket automatic slowly together, and slide block promotes to move behind piston rod, the piston, and flap is adjacent to valve body.Valve hole is sealed, and the oil in the cylinder body back segment can only carry out the cylinder body leading portion from the slit, forms resistance, makes the spring return slow, reaches the purpose of buffering.

The utility model characteristics: one is to use this device cabinet bucket automatic slowly to push return, and vibration and noise are little, and each connector is difficult for loosening, reliable operation, and product is durable, the product specification height.
