Description

A kind of drawer of any latched position

Technical field

The utility model belongs to the drawer technical field of desk, cabinet or this kind of furniture, specifically discloses a kind of any lock Position the drawer set.

Background technique

Drawer is a kind of article with function of containing articles, is usually integrally occurred with cabinet, drawer is typically designed as to extract out With the form of push-in cabinet, article is picked and placed from a drawer convenient for people.

Existing drawer usually realizes the extraction and push-in of drawer by pulley and sliding rail, but existing drawer is being taken out When out and being pushed into, can not making drawer, any position is positioned on the slide rail, so as to cause people when picking and placing the article in drawer, is taken out Drawer can generate sliding by the power that is applied when people pick and place article, and people is just needed to be determined with a hand drawer at this time Position, then gone to pick and place the article in drawer with another hand, this brings big inconvenience to the routine use of people.

Utility model content

The utility model discloses a kind of drawers of any latched position, and utility model aims to solve existing Drawer can not position on the slide rail, and lead to the drawer stress when picking and placing article and lead to the problem of sliding.

The base case of the utility model are as follows: a kind of drawer of any latched position, including drawer and guide rail, the drawer Pull ring is rotatably connected on lateral wall, the drawer lower end surface is equipped with positioning convex platform, is rotatablely connected on the positioning convex platform with teeth Wheel, the guide rail are located at below gear, and the guide rail is equipped with rack gear, and the wheel and rack engagement, the gear is for making Drawer is moved along rail length direction, and the gear is equipped with retaining mechanism for being positioned to gear, on the drawer Equipped with for driving the control mechanism of retaining mechanism, the control mechanism is controlled by pull ring.

The technical principle and beneficial effect of the utility model are: by setting retaining mechanism and control mechanism, so that working as When user picks and places the article in drawer, pull ring is pulled, so that drawer band moving gear, since wheel and rack engages, So that gear moves on rack gear under the pulling of pull ring, so that drawer moves on guide rail, when drawer pulls out enough distances Afterwards, pull ring is rotated, so that pull ring drive control mechanism, and then drive retaining mechanism by wheel gear locking by control mechanism, so that Gear can not rotate on rack gear, and then drawer during picking and placing article is avoided to slide under the effect of external force.It draws Ring is applied not only to pull out in drawer, is also used to drive control mechanism, and then drive retaining mechanism by control mechanism.

Further, the control mechanism is included out in the mounting groove on drawer outside wall, and the pull ring is in " [" font, institute It states pull ring both ends to be rotatablely connected with mounting groove two sidewalls respectively, is fixedly connected with shaft between the pull ring both ends, it is same in shaft Axis is fixedly connected with driving bevel gear, and driving bevel gear is engaged with the first drive bevel gear, and the first drive bevel gear is coaxially fixed It is connected with the first transmission shaft, the first transmission shaft other end is fixedly connected with the second drive bevel gear, the engagement of the second drive bevel gear There is third drive bevel gear, third drive bevel gear has been fixedly and coaxially connected second driving shaft, and the second driving shaft other end is fixed It is connected with the 4th drive bevel gear, the 4th drive bevel gear is engaged with output bevel gear wheel, and output bevel gear wheel has been fixedly and coaxially connected Output shaft, the output shaft other end stretch out drawer lower end surface and have been fixedly and coaxially connected output gear, and the output gear is for driving Dynamic retaining mechanism.By above-mentioned design, so that pull ring is pulled to drive shaft simultaneously, so that driving bevel gear rotates, thus The first drive bevel gear, the first drive bevel gear and then the first transmission shaft of drive and the second drive bevel gear are driven, so that Third drive bevel gear, second driving shaft and the 4th drive bevel gear are driven to rotate, and the 4th drive bevel gear drives defeated in turn Bevel gear and output shaft rotation out, so that the driving to retaining mechanism is realized in output gear rotation.

Further, the retaining mechanism includes the lock for being slidably connected on the positioning convex platform and being parallel to drawer lower end surface Mandrel is fixedly connected with locking plate on the lock shaft, and the lock shaft is rotated coaxially with gear to be connect, and is set on the lock shaft There is the tooth engaged with output gear.By above-mentioned design, so that lock shaft is driven, so that lock shaft when output gear rotation Sliding is generated relative to positioning convex platform, so that locking plate is subjected to displacement relative to gear, so that the golden disk of institute and gear push against, And then positioning of the realization to gear.

Further, the guide rail is equipped with limiting slot, and the rack gear is located in limit groove bottom.By above-mentioned design, make It obtains gear both ends of the surface and is limited groove sidewall limit, gear is avoided to skid off guide rail in the process of movement.

Further, drive cavity, first drive bevel gear, the second drive bevel gear, third are provided in the drawer wall Drive bevel gear, the 4th drive bevel gear, output bevel gear wheel, the first transmission shaft and second driving shaft are set in drive cavity, institute Output shaft one end is stated to be located at other end stretching drive cavity in drive cavity and be rotatablely connected with transmission cavity wall.By above-mentioned design, make It obtains control mechanism and is integrally located at drawer, reduce drawer volume, so that compact overall structure, is convenient for routine use.

Further, it is provided in the installation groove sidewall equipped with groove, positioning ball, the positioning steel is equipped in the groove Pressure spring is equipped between pearl and groove, the pull ring is equipped with the locating slot entered for steel ball close to the one side of groove.By above-mentioned Design, so that positioning ball is just sprung into locating slot under the action of pressure spring when pull ring turns to locating slot and is aligned with groove, So that pull ring is by steel ball card tightening position, so that compression plate keeps the state pushed against with gear.
