Abstract

The utility model relates to a rolling-ball rail self-opening sliding door. Two rows of rolling balls arranged in parallel on a movable rail roll on a roller path combined with a fixed rail to transmit force and connect to achieve the translational motion of the door. The door lock is a self-opening latch, and the door lock hook pulls a pull wire to make a counterweight move up and down by compressing and turning a handle to achieve self-opening and self-locking of the door. The utility model has the advantages of flexible opening, low noise and small occupation area. The utility model is suitable for various buildings and especially for doors of kitchens and toilets of household.

Description

Rolling-ball rail self-opening sliding door

The utility model belongs to a kind of building door.

At present, the door and window kind and the quality of building can't satisfy needs of economic development, particularly the door of house kitchen, washroom adopts vertical hinged doors, because the unlatching of door leaf, makes originally with regard to accounted for the again area of a similar square meter of hard up floor space.Therefore, a lot of places are all want to replace vertical hinged door with sliding door.Existing sliding door is to use two pair rollers, is installed in top (deck type) or following (lower support type) of door, and roller rolls on trapped orbit and realizes the switching of door.Problems such as the weight of this sliding door all concentrates on 2, causes push-and-pull dumb easily, blocks rail, and noise is big, and take a metope, also also uneconomical.In addition, existing sliding door does not have the self-opening door lock, can not solve both hands because of taking thing, the problem that can't open the door with hand.

The purpose of this utility model provides a kind of improved sliding door, and the change point load is evenly distributed load, the power of reducing friction, elimination card rail, the defective that noise is big, unlatching is dumb, floor space is big, and the automatic unlatching of realization door.

Ball slide rail self-opening sliding door of the present utility model is made up of doorframe, door leaf, track, roller, door lock, it is characterized in that:

Track is divided into fixed track and movable rail, elongated two medial surfaces that are fixed on hollow wall of fixed track, which is provided with arc groove, movable rail is fixed on the top margin both sides of door leaf, the corresponding arc groove that also is provided with the fixed track arc groove, the parallel ball of two rows is evenly arranged in the groove of movable rail, and rolls in the raceway that is synthesized by fixed track and movable rail arc groove;

Door lock is the self-opening latch, in door two side handles, respectively be fixed with a sleeve pipe, be fixed with a spring in the sleeve pipe, be provided with a push rod in the spring, one end of push rod is fixed on the handle, another termination is the inclined-plane, with door lock hook rear portion overlap joint, the middle part of door lock hook is fixed, and hook portion can upper and lower action under the promotion of push rod, and link to each other with draught line, draught line links to each other with a counterweight through doorframe top and turning pulley, and the door lock hook is hung mutually with the doorframe hook, the top of door lock hook is provided with a reed, and an end of reed is fixed on the lock housing.

Be fixed with grid spacer around the push rod in the door lock sleeve pipe.On a grid spacer, be fixed with a locking reed, when handle rotates, can stir, lock push rod.

When the trapped orbit translation of door in hollow wall, door leaf is mounted on two row's ball power transmission and connections in raceway in the movable rail arc groove.

When door is in closed condition, make the handle pressurized by a part of people, the spring in the handle is compressed, promote push rod the rear portion of door lock hook is forced down, make door lock hook compression spring, break away from the doorframe hook, and affect draught line to affect counterweight to fall by the turning pulley, and drive door slowly from opening; At closing time, counterweight rises, and the door lock hook overlaps mutually with the doorframe hook, and door promptly is in closed condition.

When this door is used for washroom etc. and need pins in door, handle is rotated, drive the locking reed push rod is dialled the decentre position, make it can not promote the door lock hook door is opened.

The utility model evenly distributes owing to ball, and like the ball bearing that flattens, so stressed even, frictional force reduces, and has switching flexibly, and noise is low, is difficult for blocking the advantage of rail; Because this door is walked in hollow wall, changed that present sliding door single face hangs and the use that influences a metope, saved building area greatly, improved function of use, if every fan door can be saved 0.5 square metre of area, annual newly-built 3,000,000 covers of then national cities and towns dwelling house (kitchen, washroom need 6,000,000 cover doors altogether) can be saved 3,000,000 square meters, average by the calculating of 600 yuan/square meter, 1,800,000,000 yuan of annual saving investments.The self-opening latch need not electronic grade than complex appts, utilize a small amount of energy that stores at closing time, when opening the door, discharge, can realize the opening certainly of door, locking function.
