Description

Linkage built-in lock structure of drawer

Technical Field

The invention relates to the technical field of drawers, in particular to a linkage built-in lock structure of a drawer.

Background

The drawers are very important storage spaces in daily life, and the cabinets and the tables are provided with the drawers which are used for storing small articles, are easy to classify, convenient to store and very wide in use. The drawer lock is an important guarantee for ensuring the safety of the property in the drawer and an important measure for protecting the privacy.

At present, most of locks in the market are provided with jacks, lock holes or lock heads are exposed outside to influence the appearance to a certain extent, and meanwhile, the locks are directly exposed outside and are easy to rust to cause lock necrosis, namely, the locks have the defect of short service life, in addition, the safety of the locks can be reduced due to obvious lock positions, the locks have the defect of low safety, and the locks are too many and are not favorable for management. Therefore, the design of the built-in lock is very necessary in many occasions and has great market demand.

Disclosure of Invention

The invention aims to provide a linkage built-in lock structure of a drawer, which aims to solve the problems in the background technology and has the advantages of simple structure, convenience in use and good safety performance.

In order to achieve the purpose, the invention provides the following technical scheme: a linkage built-in lock structure of a drawer at least comprises a first drawer and a second drawer which are arranged up and down, wherein the first drawer and the second drawer are both positioned in a cavity for placing the drawers; an air bag is arranged in the driving space, an air inlet is arranged on an upper partition plate at the driving space, the air bag is connected to the air inlet in a sealing mode, air can provide the air inlet to enter the air bag, a fulcrum seat is arranged on a lower partition plate and is hinged to the middle of a lever, one end of the lever is connected with the tail portion of a lock tongue of the lock tongue assembly, and the other end of the lever is connected with the bottom of the air bag; the outer side of the back plate exhaust hole of the first drawer is covered with a sealing plate, and the upper end of the sealing plate is fixed on the back plate.

In the initial state, because the gas in the air bag is in an atmospheric state, the bolt of the bolt assembly extends out under the action of the spring in the bolt assembly, and the bolt locks the second drawer; when the first drawer is pushed out after being opened, the first drawer is pushed rapidly by force, air in the first drawer enters a rear cavity through an air exhaust hole of the first drawer and then enters an air inlet hole in the upper partition plate, the air enters the air bag, the air bag is enlarged, the lever which is pushed out is driven to move downwards, due to the action of the lever, the tail of the tongue at the other end of the lever moves upwards, the spring tongue is separated from the locking position of the second drawer, and the second drawer can be opened at once. Certainly, the second drawer can be directly pushed in when the second drawer is closed, and the locking tongue with the inclined opening is usually adopted, so that the locking tongue is pushed up after the second drawer is closed, and then the second drawer is naturally locked by the locking tongue. The outside of the rear plate exhaust hole of the first drawer is covered with a sealing plate, the upper end of the sealing plate is fixed on the rear plate, when the first drawer is pushed out, the first drawer is rapidly pushed by force, air of the first drawer enters the exhaust hole of the first drawer into the rear cavity after the sealing plate is pushed open, then the air pressure of the rear cavity is increased, the sealing plate is naturally restored to close the exhaust hole, and the air is ensured to enter the air bag.

Preferably, when the spring bolt stretches out, the spring bolt pushes against the back plate of the second drawer, and the spring bolt can lock the second drawer in a locking structure.

Preferably, the latch bolt assembly includes a housing and a spring within the housing, the spring bearing against the end of the latch bolt. Under the normal state of the air bag, the spring drives the lock tongue to enter the lock tongue hole.

Preferably, a third drawer is arranged between the lower partition plate and the upper partition plate, and the driving space is positioned behind the third drawer.

The air bag is formed by filling compressed air or water medium into a flexible rubber capsule; the spring action is achieved by the compressibility of air and the fluidity of water.

Compared with the prior art, the invention has the beneficial effects that: the technical scheme has the advantages of simple structure, convenience in use, attractive appearance, good safety performance and the like, and has higher popularization and use values.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-7, the present invention provides a technical solution: the utility model provides a linkage built-in lock structure of drawer, includes first drawer 1, second drawer 2 and the third drawer 301 of arranging from top to bottom at least, and first drawer 1 and second drawer 2 all are located the chamber 3 of placing the drawer, and the back plate 101 of first drawer 1 is equipped with exhaust hole 102, and the outside of the back plate 101 exhaust hole 102 of first drawer 1 is covered with closing plate 103, and closing plate 103 upper end is fixed on back plate 101. The sealing plate 103 is typically a rubber sealing plate or a felt plate or the like. A built-in lock driving space 4 is arranged between the rear parts of the first drawer 1 and the second drawer 2, a third drawer 301 is arranged between the lower partition plate 303 and the upper partition plate 302, and the driving space 4 is positioned behind the third drawer 301. The driving space 4 is formed by a lower partition plate 303, an upper partition plate 302, a rear side panel 304 and a front partition plate 305, a bolt assembly 5 penetrates through the lower partition plate 303, the bolt assembly 5 comprises a bolt 501, a shell 502 and a spring in the shell 502, one end of the spring abuts against the tail end of the bolt 501, the other end of the spring abuts against the end surface of the shell 502, the bolt 501 extends out under the action of the spring in an initial state, and the bolt assembly 5 is a common structure in the prior art and is not described in more detail herein. When the latch 501 extends out, the latch 501 abuts against the back plate 201 of the second drawer 2, so that the latch 501 can lock the second drawer 2. The air bag 401 is arranged in the driving space 4, the air inlet hole 306 is formed in the upper partition plate 302 at the position of the driving space 4, the air bag 401 is connected to the position of the air inlet hole 306 in a sealing mode, air can be supplied to the air inlet hole 306 to enter the air bag 401, the lower partition plate 303 is provided with the fulcrum seat 402, the fulcrum seat 402 is hinged to the middle of the lever 403, one end of the lever 403 is connected with the tail portion of the bolt 501 of the bolt assembly 5, and the other end of the lever 403 is connected with. Bladder 401 of the present embodiment is a flexible rubber bladder that utilizes the flowability of air compressibility to achieve a resilient action.

In an initial state, because the gas in the air bag 401 is in an atmospheric state, the bolt 501 of the bolt assembly 5 extends out under the action of the spring in the bolt assembly 5, and the bolt 501 locks the second drawer 2; when the first drawer 1 is pushed out after being opened, the first drawer 1 is pushed fast by force, after the sealing plate 103 is pushed open by the air of the first drawer 1, the air enters the air outlet 102 of the first drawer 1 and enters the rear cavity 3, then the air pressure of the rear cavity 3 is increased, the sealing plate 103 is naturally restored to close the air outlet 102, and the air is ensured to enter the air bag 401.
