Abstract

The invention relates to an opening and closing mechanism, in particular to a parallel opening and closing mechanism, which is used for furniture and box covers of storage boxes of household appliances. The parallel opening and closing mechanism comprises a main body, two upper connecting rods, a parallel connecting rod, an inner shifting fork, an outer shifting fork, an outer shifting rod and a tension spring, and the two upper connecting rods, the parallel connecting rod, the inner shifting fork, the outer shifting fork, the outer shifting rod and the tension spring are mounted on the main body. The outer shifting rod is mounted on a box body capable of reciprocating, the box body corresponds to a box cover, when the box body moves towards the inside of a cabinet, namely towards the right side in a graph, the outer shifting rod on the box body can contact with the outer shifting fork before approaching to an end point of a stroke, at the moment, the outer shifting fork is positioned at the left end of the main body, a left half step of the outer shifting fork is positioned on the upper portion of an L-shaped track and hidden in the main body, the outer shifting rod only can contact with the right half portion of the outer shifting fork and can drive the outer shifting fork to move rightwards, the outer shifting fork drives the inner shifting fork to move rightwards, while a U-shaped fork of the inner shifting fork drives the parallel connecting rod to move rightwards via a small shaft in the middle of the parallel connecting rod, at the moment, the parallel connecting rod can drive the two upper connecting rods which are hinged with the parallel connecting rod to rotate around small shafts in middles of the two upper connecting rods, and front ends of upper portions of the two upper connecting rods are in arc movement towards the left lower sides. Accordingly, the box cover which is hinged with ends of the two upper connecting rods via two points can move towards the left lower side, and the box cover is closed. The box cover is opened by the aid of a reverse movement process.

Description

Parallel open-and-close mechanism

Technical field:

The present invention relates to a kind of open-and-close mechanism, particularly a kind of parallel open-and-close mechanism that is used for the storage tank case lid of furniture and family expenses apparatus.

Background technology:

Mostly the case lid of the storage tank of existing furniture and family expenses apparatus is to raise manually, also has some to use line to draw upset and gravity upset; But it is reliable and stable inadequately that its shortcoming is work; And taken bigger space, reduced storage space, degree of automation is also not enough.Therefore, be necessary to develop and a kind ofly take up room for a short time, lid can easily be opened when looking on the bright side of things with storage tank, the parallel open-and-close mechanism of the storage tank case lid of the automation that can fit together perfectly again when closed.

Summary of the invention:

The present invention realizes through following technical scheme: the parallel open-and-close mechanism of the present invention is by main body, and be installed in two boxed rods on the main body, flat connecting rod, interior shift fork, outer shift fork, outer driving lever, extension spring, form.Outer driving lever be installed in the corresponding reciprocating casing of case lid on, when casing when cabinet inside just illustrates right-hand motion, the outer driving lever on it can be before near end of run; Touch outer shift fork; This moment, outer shift fork was the left end in main body, and half step of an outer shift fork left side is hidden in the main body on the top of L shaped track; Outer driving lever can only be run into the right-hand part of outer shift fork; To drive outer shift fork and move to right-hand, outer shift fork drives interior shift fork to right-hand mobile, and the U-shaped of interior shift fork fork will move right through the flat connecting rod of little drive at flat connecting rod middle part; Flat connecting rod can drive and the little axle rotation along the intermediate portion of two boxed rods of its pivotally attached this moment, and makes its top front end do a circular motion to the lower left.Then with 2 case lids that are hinged in its end, just motion is down left closed case lid, otherwise is then opened case lid.

Interior shift fork is one will through the fork of the U-shaped on it, drive parallel rod by the parallel crank motion of outer driving lever transmission, and two boxed rods are moved in the stepping of going forward side by side, and describe the key element of oscillating motion.

By two boxed rods, case lid, and flat connecting rod has been formed four-bar linkage.

An ability and interior shift fork U-shaped groove are processed in flat connecting rod middle part, cooperate the little axle that slides.

Outside on main body, making shift fork and in shift fork slip therein be roughly L shaped groove.

The present invention and original compared with techniques are uncapped like the wire-pulling type of original technology, and when storage tank offerd for sale, case lid had been drawn one and half gardens aloft; Open case lid, when returning in the locker, backguy is loosened, and case lid is closed; Obvious case lid has been drawn one and half gardens aloft, and occupied than large space, thereby reduced the space of storing, and the case lid among the present invention; Just make a parallel opening and closing movement, above casing, take up space, be no more than 20 millimeters; Bigger saving the space, the storage tank volume is heightened, thereby can store more article.

Among the figure: 1, main body, 2, case lid, 2a, casing, 3, boxed rod 1, axle on 3a, the boxed rod 1; 3b, boxed rod 1 axis, 3C, boxed rod 1 lower shaft, 4, boxed rod 2, axle on 4a, the boxed rod 2,4b boxed rod 2 axis, 4C boxed rod 2 lower shafts; 5, flat connecting rod, 5a, flat connecting rod tween drive shaft, 6, interior shift fork, little axle behind 6a, the interior shift fork, little axle before 6b, the interior shift fork, 7, outer shift fork; 7a, outer driving lever, the little axle of 7b, outer shift fork, 8, guide groove, 9, extension spring, 10, the escapement main body, 11, the escapement shift fork; 12, the reefer chamber of refrigerator, 13, slide rail, 14, backguy, 15, stay-supported storage tank case lid, 16, S. A..

The specific embodiment:

Embodiment: be used for the preservation of vegetables case that refrigerator and cooled is hidden cabinet: see Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8:

Fig. 5, Fig. 6 are the lateral plans of refrigerator, and the preservation of vegetables case is positioned at the bottom of reefer chamber; When needs are got, during glove, open refrigerator doors, touch casing with have gentle hands; Then escapement 10 discharges casing 2a, and outwards ejects, and this moment, outer shift fork 7 of outer driving lever 7a drive as figure were to left movement.Shift fork 6 left movements in outer shift fork 7 drives through the little axle of interior shift fork 6b; Interior shift fork 6 drives flat connecting rod tween drive shaft 5a through the fork of the U-shaped on it; And drive flat connecting rod 5 through 5a and do parallel motion to the upper left side, flat connecting rod 5 drives boxed rod 3 and boxed rod 4 around little axle 3b and little axle 4b clickwise through little axle 3c and little axle 4c, and boxed rod 3 and boxed rod 4 tops little axle 3a and 4a and case lid 2 are hinged; So cover 2 mutually also to the upper right side parallel motion, also promptly opened case lid 2.This moment, casing was ejected when left terminal point, just desirable, glove.

Be recovered to right-hand and close case lid like the need casing, only with hand touches casing to end of run, and at this moment, mechanism action is opposite with the lid of unpacking, and escapement pins casing, and mechanism closes case lid.

Same principle of work, this parallel open-and-close mechanism can also be used for clothing and store occasions such as rubbish storage.
