Abstract
The present invention relates to a kind of drawer for refrigerator cushioning self-tightening, belong to refrigerator manufacturing technology field.Comprise: be located at the bumping post on the refrigerator madial wall relative with drawer side surface, be located at the L bracket of the side of drawer; The horizontal side of the L shape of support is shaped with dog hole, the vertical side of support L shape is fixed with spring, the other end of spring is towards drawer afterbody and be fixedly connected with sketch plate, sketch plate is divided into two pieces of baffle plates and hook plate of being connected with each other, the bottom of hook plate is shaped with the hook that can hook dog hole, the junction of baffle plate and hook plate is formed and is positioned at identical level height with bumping post and the groove that can hold bumping post, and baffle plate and hook plate extend two hypotenuses in sharp clevis angle respectively from its junction to the afterbody of drawer.Present invention, avoiding the defect that existing Drawer of freezer uses, fully cushioned with contacting of contact by column cap before door seal contact casing, then by the pulling force of spring, drawer is tightened up, thus realizes self-locking.
Description
Technical field
The present invention relates to a kind of drawer for refrigerator cushioning self-tightening, belong to refrigerator manufacturing technology field.
Background technology
General known Drawer of freezer on the market generally adopts magnet door seal at present, and drawer slides and relies on scroll wheel.When drawer try hard to recommend outside dynamic under, door seal is close to casing, and when being close to a certain degree, when the attraction of magnet is greater than the frictional force of drawer runner system, drawer just no longer needs external force to fasten voluntarily.But when external force is larger, the impact casing that drawer can be fierce, door seal and casing are all subject to larger impulsive force, and thus, namely the corner welding place of door seal has the risk of cracking, reduce service life.Meanwhile, vibrations and the noise that also can cause casing of impulsive force, bring impact to the experience of user.
Summary of the invention
The technical problem that the present invention solves is: propose a kind of can to cushion and can the Drawer of freezer structure of self-locking.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: a kind of drawer for refrigerator cushioning self-tightening, and the madial wall that described refrigerator is relative with described drawer side surface is provided with bumping post, is provided with the support of L shape in the side of described drawer, the horizontal side of the L shape of described support is shaped with dog hole, the vertical side of described support L shape is fixed with spring, the other end of described spring is towards described drawer afterbody and be fixedly connected with sketch plate, described sketch plate is divided into two pieces of baffle plates and hook plate of being connected with each other, the bottom of described hook plate is shaped with the hook that can hook described dog hole, the junction of described baffle plate and hook plate is formed and is positioned at identical level height with described bumping post and the groove that can hold described bumping post, described baffle plate and hook plate extend two hypotenuses in sharp clevis angle respectively from its junction to the afterbody of described drawer, when described drawer is closed, described sketch plate moves towards bumping post, first the hypotenuse that described bumping post presses described hook plate makes described sketch plate rotate backward around bumping post, after described drawer is continued to advance, described bumping post enters groove and forms the fulcrum making sketch plate form lever, described sketch plate rotates forward around bumping post and levers up, described hook departs from described dog hole, described sketch plate and described bumping post clamp, described Drawer of freezer is fastened under the active force of described spring, when described drawer open, described sketch plate dorsad bumping post moves, and described bumping post departs from groove, and described sketch plate rotates backward around bumping post and falls, and described hook hooks described dog hole, described spring is in extended state.
Further improvement of the present invention is:
1. spring described in is extension spring.
2. bumping post described in is cylindrical.
3. groove described in is square.
4. described in, hook is in tip-angled shape.
The beneficial effect that the present invention brings is: present invention, avoiding the defect that existing Drawer of freezer uses, when the end of closing drawers (before door seal contact casing), fully cushioned with contacting of sketch plate by bumping post, the impact produced under external force when effectively avoiding drawer to close, reduce the damage of drawer, extend drawer life cycle.When entering the groove on sketch plate afterwards when bumping post; even if unclamp external force; drawer makes drawer be fastened with contacting of sketch plate by the pulling force of spring by bumping post; thus self closing is realized to drawer and forms fully buffering; when Drawer of freezer needs to be opened time; the strength opening Drawer of freezer must be greater than the pulling force that spring produces and Drawer of freezer could be pulled open, and makes children not open Drawer of freezer like this, and then protects the safety of children.

Detailed description of the invention
Embodiment one
The drawer for refrigerator of the buffering self-tightening of the present embodiment, as depicted in figs. 1 and 2, the madial wall that refrigerator 10 is relative with drawer 1 side is provided with bumping post 9, and bumping post 9 is cylindrical; The support 3 of L shape is provided with in the side of drawer 1; The horizontal side of the L shape of support 3 is shaped with dog hole 7, the vertical side of support 3L shape is fixed with spring 2, in the present embodiment, spring 2 adopts extension spring, and spring 2 is in the state of stretching always, the other end of spring 2 is towards described drawer afterbody and be fixedly connected with sketch plate 11, sketch plate 11 is divided into two pieces of baffle plates be connected with each other 4 and hook plate 5, and the bottom of hook plate 5 is shaped with the hook 6 that can hook dog hole 7, and linking up with 6 outward appearances is tip-angled shape.The junction of baffle plate 4 and hook plate 5 is formed and is positioned at identical level height with bumping post 9 and the groove 8 that can hold bumping post 9, and groove 8 is square.Baffle plate 4 and hook plate 4 extend two hypotenuses in sharp clevis angle respectively from its junction to the afterbody of drawer, when drawer 1 is closed, sketch plate 11 moves towards bumping post 9, first the hypotenuse that bumping post 9 presses hook plate 5 makes sketch plate produce small rotating backward around bumping post 9, and then make spring 2 produce small stretching, this part generation by spring 2 is stretched, and cushions drawer 1; When overcoming spring 2 for after the active force that cushions, drawer 1 is advanced by continuation, bumping post 9 enters groove 8 and forms and makes sketch plate 11 form the fulcrum of lever, sketch plate 11 rotates forward around bumping post 9 and levers up, hook 6 departs from dog hole 7, sketch plate 11 and bumping post 9 clamp, and drawer 1 is fastened under the active force of spring 2; When drawer 1 pulls open, sketch plate 11 dorsad bumping post 9 moves, and bumping post 9 departs from groove 8, and sketch plate 11 rotates backward around bumping post and falls, and hook 6 hooks dog hole 7.
The drawer for refrigerator of buffering self-tightening of the present invention is not limited to the concrete technical scheme described in above-described embodiment, and all employings are equal to replaces the shape etc. that the technical characteristic formed such as changes groove, bumping post, hook, is the protection domain of application claims.
