Abstract

The utility model belongs to steel ball braking type mortise lock. In the utility model, the inner of a lock box is provided with a sliding rack, when two steel balls are compressed in steel ball holes and under the action of a spring which is arranged behind the sliding rack, the sliding rack slides forward and a bolt is ejected from a bolt mouth, and under the action of a turning button, the bolt drives the sliding rack to slide downwardly, the steel balls brake automatically when the steel balls slide to the steel ball holes. The utility model has the advantages of artful structure, convenient use, convenient installation, flexible action and reliable performance, and the utility model can be widely used for doors, windows and furniture.

Description

Steel ball braking type mortise lock

The utility model relates to a kind of latch or affixed device that is used for door or window, particularly a kind of steel ball brake type latch.

At present because the develop rapidly of modern architecture, interior decoration is the explicit culture artistic color, door and window by senior aluminium close, the steel moulding material replaces.For annexes such as those door and windows and locksets, it is of poor quality still to keep appearance so far, and material is single, and the latch of functional defect, handle, hinge etc. form strong contrast with the door and window of the building in modern times and modern life style.For overcoming these problems, the utility model has designed a kind of brake type latch, and it has the appearance exquisiteness, and technology is simple, the characteristics of dependable performance.

The purpose of this utility model provides a kind of steel ball brake type latch.

The technical program is: streamlined steel ball brake type latch is a metal sheet of selecting for use 0.8-1.0mm thick, through punching press, blanking, pull and stretch, technology such as curved manufactures streamlined lock box, stamp out the two ends ear at its lock box end place, on its two ends ear, has fixing hole, on its lock box, stamp out the switch knob slide groove respectively, steel ball hole and lock-tongue port, in its lock box, has a travelling carriage, travelling carriage is the ⊥ font, one end of ⊥ font has a dead bolt, the other end has a groove-shaped frame, in its groove-shaped frame, have two springs, front end at two springs is equipped with a steel ball, has a spring anchorage bracket in the centre of two springs, a spring is housed in spring anchorage bracket, dead bolt stretches out by lock-tongue port, the steel ball of two springs is fixed by the steel ball hole, spring in spring anchorage bracket touches mutually with a end face in the lock box, when making two steel balls be compressed in the steel ball hole under the active force of a spring thereafter, make travelling carriage to front slide, and dead bolt is ejected from lock-tongue port, when dead bolt drive travelling carriage was slided backward, braking was fixing when making steel ball slide into the steel ball hole.This moment, dead bolt was with setback lock-tongue port antetheca zero line position, and simultaneously propelling spring to be becoming the full load compressive state, and two springs are implemented to discharge in the travelling carriage, and the area in two steel balls contact steel ball hole only is 2/5ths of steel ball hole.

On dead bolt, connect a switch knob by the switch knob slide groove.

Have a base plate in the bottom surface of its lock box, the fixing hole on the two ends ear on base plate and the lock box is become one by the coupling ring riveted joint.

The utility model compared with prior art, have simple in structure, deft design, easy to install and use, flexible movements, dependable performance, the characteristics that have attractive appearance, and can be widely used in door, window and furniture.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is a sectional structure schematic diagram of the present utility model;

Fig. 3 is Fig. 1 broken section structural representation.

Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.

Embodiment

See shown in Fig. 1-3: streamlined steel ball brake type mortise lock is a metal sheet of selecting for use 0.8-1.0mm thick, through punching press, blanking, pull and stretch, technology such as curved manufactures streamlined lock box 1, stamp out two ends ear 5 at its lock box 1 end place, on its two ends ear 5, has fixing hole 4, on its lock box 1, stamp out switch knob slide groove 2 respectively, steel ball hole and lock-tongue port, in its lock box 1, has a travelling carriage 13, travelling carriage 13 is the ⊥ font, one end of ⊥ font has a dead bolt 7, the other end has a groove-shaped frame, in its groove-shaped frame, have two springs 9, front end at two springs is equipped with a steel ball 3, has a spring anchorage bracket 11 in the centre of two springs 9, a spring 12 is housed in spring anchorage bracket 11, dead bolt 7 stretches out by lock-tongue port, the steel ball 3 of two springs 9 is fixed by the steel ball hole, spring 12 in spring anchorage bracket 11 touches mutually with a end face in the lock box 1, when making two steel balls 3 be compressed in the steel ball hole under the active force of a spring 12 thereafter, make travelling carriage 13 to front slide, and dead bolt 7 is ejected from lock-tongue port, when dead bolt 7 drive travelling carriages 13 were slided backward, braking was fixing when making steel ball 3 slide into the steel ball hole.This moment, dead bolt 7 was with setback lock-tongue port antetheca zero line position, and simultaneously propelling spring 12 to be becoming the full load compressive state, and two springs 9 are implemented to discharge in the travelling carriage 13, and the area in two steel balls, 3 contact steel ball holes only is 2/5ths of steel ball hole.

On dead bolt 7, connect a switch knob 8 by switch knob slide groove 2.

Have a base plate 6 in the bottom surface of its lock box 1, the fixing hole 4 on the two ends ear 5 on base plate 6 and the lock box 1 is connected into by coupling ring riveting 10 and is one.
