Abstract
The invention relates to an invisible magnetic connecting device for vertically connecting two plates. The invisible magnetic connecting device can be automatically and unidirectionally locked through the movement of a ball between a connecting sleeve and the conical surface of a ball sleeve, and the automatically locked invisible connecting device can be loosened outside a connecting plate by using the attractive force of a magnet to a steel material, so that the problem that a part of the common detachable connecting piece is always exposed outside the connecting plate is solved, and the device can be used for connecting panel furniture.
Description
Technical field:
The present invention relates to a kind of connection set, specifically is a kind of hidden magnetic connection set connected vertically between two plates that is used for.
Background technique:
At present, in furniture industry, adopt dismountable plank frame usually, plate and plate are vertical be connected in often a kind of embedded link of utilization (promptly three-in-one) connect.Three-in-onely form by the bolt that rises, bolt, eccentric part three parts.The bolt outer surface that rises has the hangnail of projection can increase friction with sheet material, and the bolt that rises has internal thread to be connected with bolt.One end of bolt is that screw thread can connect with rising to tie, and the other end has neck, can embed in the locking slot of eccentric part.Eccentric part has the Camlock groove and can rotate in the hole.Before the installation, in two plates of preparing to connect, beat straight hole at attachment face for one and be used for installing the bolt that rises, another piece is at attachment face and inner side surface is beaten mutual UNICOM and vertical hole is used for construction bolt and eccentric part.During installation, the bolt that will rise earlier is pressed in the straight hole of accomplishing fluently in advance, is installed on bolt in the bolt that rises and tightens, and has neck one end to insert in the hole of another piece plate attachment face on bolt, and the hole that eccentric part is put into inner side surface is caught on the neck of bolt and tightened.This Placement need be rotated eccentric part from the outside with screw-driver, and the silhouette that eccentric part can be exposed at plate rings attractive in appearance; Eccentric part after the locking is loosening easily under external force effects such as vibration, twisting, influences working life.
Summary of the invention:
The object of the present invention is to provide a kind of magnetic connector of stealth, can utilize magnet that the attraction force of ferrous materials is unclamped the stealthy connection set of auto lock outside connecting plate, always some is exposed to the problem of connecting plate outside to have solved common removable connector.
Design proposal of the present invention: a kind of hidden magnetic connection set, form by inserting member, locking element two-part.Inserting member is stepped axle shape, divides thread section, taper positioning section and inserts section.Locking element is made up of connecting sleeve, ball cover, spring and depression bar.Connecting sleeve is made up of coaxial positioning hole, cone shape hole and straight hole, and positioning hole cooperates with the taper positioning section of inserting member, and cone shape hole is installed the ball cover, and straight hole is used for mounting spring and depression bar.The ball cover is an internal diameter inserts the section diameter greater than inserting member a sleeve.Ball cover circumferencial direction has radial direction through hole, the shape of radial direction through hole is a cone shape hole, the through-hole diameter that is positioned at the connecting sleeve cone shape hole conical surface one end is greater than the through-hole diameter that is positioned at ball cover internal diameter one end, and is positioned at the diameter of the through-hole diameter of ball cover internal diameter one end less than ball 4.The ball cover can move along axial direction in connecting sleeve.Ball places in the radial direction through hole and can move radially along through hole.Spring is connected with depression bar with ball holder cover respectively.Depression bar is step-like cylindrical body, and an end is connected with spring in connecting sleeve, and step is pushed down the connecting sleeve end face.
The auto lock of hidden magnetic connection set of the present invention is realized with unclamping in the following way.
Ball is packed in the radial direction through hole of ball cover, in the connecting sleeve of again the ball cover being packed into, in the connecting sleeve of then spring and depression bar being packed into.When inserting member inserts, ball is enclosed within the effect lower compression spring of inserting member thrust and moves to the spring direction, ball outwards moves in radial direction through hole, when that formed diameter of a circle of the most close ball cover of the ball axis on being installed on ball cover circumferencial direction equals the diameter of inserting member insertion section, ball in the ball cover just in time is stuck in inserting member and inserts between the section and the connecting sleeve cone shape hole conical surface, because the effect of the cone shape hole conical surface, at this moment, inserting member can only move and can not oppositely extract out to the spring direction, reaches the purpose of automatic one-way locking.When be given a shock, external force such as twisting does the time spent because the pressure of spring, ball will be stuck in inserting member all the time and insert between the section and the connecting sleeve cone shape hole conical surface, can not produce loosening.When needs are taken apart, place strong magnet in fixing body outer lock piece proceeds posterolateral, under the effect in strong magnet magnetic field, the ball cover moves with pressure spring and to the spring direction, be installed on the ball cover circumferencial direction ball radially through hole outwards move, when that formed diameter of a circle of the most close ball cover of the ball axis on being installed on ball cover circumferencial direction inserted the diameter of section greater than inserting member, ball no longer produced active force to the insertion section of inserting member, can like a cork inserting member be extracted out.
The present invention compares with existing connection set and has the following advantages
1, use this hidden magnetic connection set can realize auto lock.
2, this hidden magnetic connection set is hidden in two connecting plate inside fully.
3, use the installation and removal of this hidden magnetic connection set convenient,

Embodiment:
Be described further below in conjunction with accompanying drawing:
As shown in Figure 1, hidden magnetic connection set of the present invention is made up of inserting member and locking element two-part.
Before the installation, earlier with the thread section of inserting member 1 be fixed in rising in the connecting body in advance and tie and connect.Ball 4 is packed in the radial direction through hole of ball cover 3, and the ball cover 3 that ball 4 will be housed is again packed in the connecting sleeve 2, in the connecting sleeve of then spring 5 and depression bar 6 being packed into.The locking element that assembles is pressed in the hole that another connecting body accomplishes fluently in advance, guarantees that locking element and connecting body are connected firmly.
During installation, inserting member 1 is inserted in the hole of the positioning hole of locking element connecting sleeve 2 and ball cover 3, ball 4 inserts between the section and the connecting sleeve 2 cone shape hole conical surfaces being stuck in inserting member 1 under the effect of spring 5 all the time, realizes automatic one-way locking.
During dismounting, place strong magnet in fixing body outer lock piece proceeds posterolateral, under the effect in strong magnet magnetic field, ball cover 3 moves with pressure spring 5 and to spring 5 directions, be installed on ball overlap on 3 circumferencial directions ball 4 radially through hole outwards move, ball 4 no longer produces active force to the insertion section of inserting member 1, can like a cork inserting member 1 be extracted out.
