Abstract
The utility model aims to provide a novel falsely-unlocking preventing device, which is mainly composed of a shaft sleeve, a turning wheel with a special line slot, a thimble, a spring, a lock bar and a nut, wherein a round hole in the bottom of the shaft sleeve can cause the lock bar to penetrate, and the lock bar and the nut causes the turning wheel to be put in the middle through threaded connection to form a synchronous rotation body; and the synchronous rotation body is arranged in the shaft sleeve, then the thimble and the spring are arranged in a cylindrical hole in the side edge, and the rear end of the spring is tightly abutted. The shaft sleeve and the turning wheel is formed by alloy die-casting or injection molding processing, and the lock bar, the nut and the thimble are formed by metal rod mechanical processing. The novel falsely-unlocking preventing device has a simple structure, low cost and simple manufacture process, can be put into standardized mass production by utilizing industrial copy, is convenient to operate and use, is matched with hardware locks such as single-point locks so as to obviously increase the safety performance of the locks, and is particularly suitable for households, public places and hotels.
Description
Technical field
The utility model relates to the five metals field of lockset, especially a kind of important accessory of single-point locking device, a kind of mistaken opening preventer.
Background technology
Present some traditional five metals locksets, particularly for the lockset on the window, do not have locking functions or the simple exposed part that have are used as the lockset safeties, and this is opened by the baby is virgin easily, thereby makes lockset lose due protective action; What have then selects conventional lock cylinders, possessed to prevent the virgin function of opening lockset of baby, yet this is easy to cause because forgeing key and causes escape difficult.
Summary of the invention
The utility model is for the deficiency of existing product, technology, and it is ingenious to aim to provide a kind of design, makes, mistaken opening preventer easy to use.
The purpose of this utility model is achieved in that a kind of mistaken opening preventer, formed by an axle sleeve, runner with special wire casing, thimble, spring, locking bar and nut, its structure is that axle sleeve top is provided with nut, axle sleeve inside is provided with a runner, the axle sleeve bottom is provided with a circular hole, and from top to bottom, nut is threaded connection runner, locking bar places the axle sleeve bosom, form a synchronous rotary body, locking bar passes circular hole.Runner is irregular by 1/4th circles, be transitioned into the arc of horizon wire casing of runner cylindrical from certain degree of depth, the crossing screw thread wire casing of two sections degree of depth differences, opposite direction, and straight-line groove forms; Arrange one at an end of larger that section screw thread of the degree of depth and connect the starting point of first screw thread and the terminal point of second screw thread with vertical direction straight-line groove at an angle.A hole of placing thimble and spring is set in the side of axle sleeve, and the height of runner arc of horizon wire casing all is slightly larger than the diameter of thimble, spring thimble can push up in the arc of horizon wire casing wire casing of runner.
The utlity model has following beneficial effect:
This device design is ingenious, and it is convenient to open, and need not by key; Action behavior ability according to baby child designs, and has the effect that very strong anti-baby child opens by mistake; According to the effect characteristics, the intensity of each component of reasonable distribution; Low cost, sound construction, applied range.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model rotaring wheel structure schematic diagram.
Number in the figure explanation: axle sleeve 1, runner 2, thimble 3, spring 4, locking bar 5, nut 6, arc of horizon wire casing 7, screw thread wire casing 8, straight-line groove 9, hole 10.
The below further describes structure of the present invention and principle:
The specific embodiment:
A kind of mistaken opening preventer, formed by an axle sleeve 1, runner 2 with special wire casing, thimble 3, spring 4, locking bar 5 and nut 6, its structure is that axle sleeve 1 top is provided with nut 6, axle sleeve 1 inside is provided with a runner 2, axle sleeve 2 bottoms are provided with a circular hole 10, and from top to bottom, nut 6 is threaded connection runner 2, locking bar 5 places axle sleeve 1 bosom, form a synchronous rotary body, locking bar 5 passes circular hole 10.Runner 2 is irregular by 1/4th circles, be transitioned into 7, two sections degree of depth differences of arc of horizon wire casing of runner 2 cylindricals, the crossing screw thread wire casing 8 of opposite direction from certain degree of depth, and straight-line groove 9 forms; Arrange one at an end of larger that section screw thread of the degree of depth and connect the starting point of first screw threads and the terminal point of second screw thread with vertical direction straight-line groove 9 at an angle.A hole 10 of placing thimble 3 and spring 4 is set in the side of axle sleeve 1, and the height of runner 2 arc of horizon wire casings 7 all is slightly larger than the diameter of thimble 3, spring thimble 3 can push up in the arc of horizon wire casing 7 of runner 2.
Embodiment: this device is installed on the product, only needs one aperture to be set than the slightly large circular hole of locking bar 5 bottom diameters in the lower end of locking bar 5 flexible directions, by rotary nut 6, locking bar 5 can be realized stretching.When the unlatching track rotary nut 6 according to design; first toward a direction rotation nut 6; thimble 3 stretches into second segment screw thread wire casing 8 from first paragraph screw thread wire casing 8; the synchronous rotary axon is to the first paragraph distance that moves up; locking bar 5 is retracted to a height; this hour locking lever 5 does not stretch out circular hole fully; toward rightabout nut 6 is rotated to the end again; the rotary body second segment distance that axially moves up; locking bar 5 shrinks fully; this hour locking lever 5 stretches out circular hole fully, removes this unit protection state, namely remove the product component that will limit play limit its with locking bar 5 axially vertical directions move.This moment, thimble 3 was blocked by the sidewall of the axially directed groove of runner 2, can't continue rotation.And nut 6 is pressed downwards, thimble 3 upwards slides into from the straight-line groove 9 at the other end of larger that section screw thread of the degree of depth, and the synchronous rotary axon can realize that to moving down the synchronous rotary body returns to locking bar 5 and stretches out the longest position, axle sleeve 1 lower end.So, repeatedly work.
By above-mentioned opening ways, this device has increased the difficulty of child greatly, has played the effect that anti-children open by mistake, and has effectively protected children's safety.
The stroke height of this device first paragraph and second segment screw thread and direction can be carried out adjusted design according to the concrete mated condition of product, thereby reach the exact matching with product.
Protection domain of the present utility model is not limited only to above example, and all contents identical with the technical solution of the utility model or that be equal to all fall into the protection domain of the utility model.
