Embodiment Construction

[0016] Further explanation is given below in conjunction with accompanying drawings:

[0017] Such as figure 1 As shown, the invisible magnetic connection device of the present invention consists of two parts: an inserting part and a locking part.

[0018] Before installation, the threaded section of the insert 1 is connected with the expansion bolt previously fixed in the connecting body. Put the ball 4 into the radial through hole of the ball sleeve 3, then put the ball sleeve 3 with the ball 4 into the connecting sleeve 2, and then put the spring 5 and the pressure rod 6 into the connecting sleeve. Press the assembled locking piece into the pre-drilled hole of another connecting body to ensure that the locking piece is firmly connected with the connecting body.

[0019] When installing, insert the insert 1 into the positioning hole of the locking piece connecting sleeve 2 and the hole of the ball sleeve 3, and the ball 4 is always stuck on the insert section of the insert...

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: [0001] The invention relates to a connection device, in particular to an invisible magnetic connection device used for vertical connection between two boards. Background technique: [0002] At present, in the furniture industry, a detachable panel structure is usually used, and an embedded connector (that is, a three-in-one) connection is often used in the vertical connection between panels. Three-in-one is composed of three parts: expansion bolt, bolt and eccentric part. There are raised barbs on the outer surface of the expansion bolt to increase the friction with the plate, and the expansion bolt has internal threads to connect with the bolt. One end of the bolt is threaded and can be connected with the expansion bolt, and the other end has a neck, which can be embedded in the locking groove of the eccentric. The eccentric has an eccentric locking groove and can be rotated in the hole. Before installation, among the two plates to be connected, one has ...
