Description

An emergency escape lock sleeve device for an anti-theft door

technical field

The invention relates to an emergency escape lock sleeve device for an anti-theft door, belonging to the technical field of locks.

Background technique

People indoors cannot avoid encountering some accidents, and fire is a common accident. When running into sudden accidental danger, people in the room are very likely to be unable to open the door due to panic, especially when the door is locked indoors. Therefore, designing an unlocking device that can escape quickly is of great significance to ensuring the life safety of indoor personnel.

Usually the anti-theft door lock is designed to use the movement of the pull rod and the knob fixed on the door to pull the deadbolt to open the door. The blockage of the pull rod mechanism makes the door temporarily stuck or takes too long to unlock, which delays the precious time for people to escape from danger and poses a threat to life.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings of the existing anti-theft doors that are slow to unlock indoors, and provide an emergency escape lock sleeve device for anti-theft doors, which can be conveniently and quickly opened for emergency escape locks for anti-theft doors in case of sudden accidents such as fire set.

The technical solution adopted by the present invention to solve the problems of the technologies described above is:

The present invention is an emergency escape lock sleeve device for anti-theft doors, which is mainly composed of a lock sleeve, a slider, a chute, a screw and a pin. The pin hole, the lock sleeve and the slider are connected by screws and the holed end face of the lock sleeve is aligned with the slider. There is a combined through hole at one end of the slider. The combined through hole is composed of a lower large-diameter hole and an upper small-diameter hole. A through hole with the same diameter as the large diameter hole in the lower part of the slider combined through hole is opened at the position where the groove and the slider combined through hole are coaxial. The groove and the slide block are limited by a pin combination, and the pin combination is composed of a pin, a spring and a nut. One end of the pin has a boss for fixing the spring, and the other end of the pin is a threaded joint for connecting the nut.

The shape of the chute of the chute is dovetail-shaped, the chute of the chute is partially opened, the length of the chute should be opened to ensure that the lock sleeve slides to the position where the lock tongue is completely exposed, and the diameter of the through hole on the chute Larger than the largest diameter of the pin, allowing the pin to move up and down easily.

The shape of the slider is dovetail, the diameter of the boss of the pin is larger than the diameter of the small hole of the combined through hole in the slider, the large diameter end of the pin is smaller than the diameter of the big hole of the combined through hole in the slider, and the diameter of the boss The height is smaller than the height of the large-diameter hole at the bottom of the combined through hole, so that the boss can all be moved to the inside of the slider, so that the pin does not limit the sliding of the slider.

Beneficial effect and advantage of the present invention are as follows:

The present invention changes the previous way of opening the door by opening the lock bolt to the way of opening the door by moving the lock sleeve, and transforms the complex and cumbersome emergency unlocking mechanism inside the lock into the emergency unlocking by the lock sleeve. The structure is simple, convenient and fast to use, and the structure is reliable. High durability and long service life.

detailed description

The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

As shown in Fig. 1, Fig. 2 and Fig. 3, an emergency escape lock sleeve device for an anti-theft door of the present invention is mainly composed of a lock sleeve 1, a slider 2, a chute 3, screws (4, 5) and a pin combination 9 One end of the lock sleeve 1 is provided with a cuboid deadbolt hole 10 and two cylindrical anti-lock pin holes 11, the lock sleeve 1 and the slider 2 are connected by screws (4, 5) and the end face with holes of the lock sleeve 1 is connected with the The slider 2 is aligned; one end of the slider 2 is provided with a slider combination through hole 12, the slider combination through hole 12 is composed of a lower large-diameter hole and an upper small-diameter hole, and the chute 3 is coaxial with the slider combination through-hole 12 There is a through hole with the same diameter as the large diameter hole in the lower part of the slider combination through hole 12 at the position of the slider; the chute 3 is fixed on the door frame position where the bolt hole 10 of the lock sleeve 1 can work with the lock tongue, and the chute 3 and the chute Block 2 is limited by pin combination 9, and described pin combination 9 is made up of pin 6, spring 7 and nut 8, and one end of pin 6 has boss 13, is used for fixing spring 7, and the other end of pin 6 is threaded joint, uses To connect the nut 8.

The shape of the chute of the chute 3 is dovetail-shaped, the chute of the chute 3 is partially open, the length of the chute should be opened to ensure that the lock sleeve 1 slides to the position where the dead bolt is completely exposed, and the upper chute 3 The diameter of the through hole is larger than the maximum diameter of the pin 6, so that the pin 6 is easy to move up and down.

The shape of the slider 2 is dovetail, the diameter of the boss 13 of the pin 6 is larger than the small hole diameter of the slider combination through hole 12, and the large diameter end of the pin 6 is smaller than the large hole diameter of the slider combination through hole 12 , the height of the boss 13 is smaller than the height of the large-diameter hole at the bottom of the slide block combination through hole 12, so that the boss 13 can all be moved to the inside of the slide block 2, so that the pin 6 does not limit the sliding of the slide block 2.

In Fig. 1, under normal circumstances, the lock sleeve 1 is fixed on one end of the chute 3 by the pin 6, so that the lock sleeve 1 is accurately fixed on the correct position of the door frame, and the lock can work normally; During an accident, the people in the house pull the nut 8 on the pin 6 immediately, and the lock sleeve 1 can be quickly slid from the original position to the other end of the chute 3 by compressing the spring 7, and the lock sleeve 1 fixedly connected with the slide block 2 Also brought to the other end away from the deadbolt, so that the deadbolt is fully exposed and not restricted by the deadbolt hole 10 and the cylindrical anti-lock pin hole 11 of the lock sleeve 1 .

In Fig. 1, the lock sleeve 1 can slide together in the chute 3 through the inner dovetail slider 2 connected thereto, and the baffle plate at the right end of the slideway of the chute 3 prevents the lock sleeve 1 from sliding down.

In Fig. 2, the spring 7 passes through the pin 6, the boss 13 at the large diameter end of the pin 6 blocks one end of the spring 7, and the threaded small diameter end of the pin 6 passes through the combined through hole on the slider 2 and is connected with the nut 8.

In Fig. 3, the chute 3 has a through hole, and the chute 3 and the cylindrical section of the boss 13 on the pin 6 adopt a clearance fit, which is convenient for the pin 6 to come in and out freely, and the slider 2 on the lock sleeve 1 has a slider combination Through hole 12, the diameter of the large-diameter hole at the bottom of the combined through-hole 12 of the slider and the large-diameter end boss 13 of the pin 6 adopt a clearance fit, and the depth of the large-diameter hole at the bottom of the combined through-hole 12 of the slider is greater than that of the boss of the pin 6 13 heights are large, and the diameter of the small hole on the upper part of the slide block combination through hole 12 is smaller than the inner diameter of the spring 6.
