The second hinge portion includes two ear plates 203 integrally formed with the transition neck portion 202, respectively, the ear plates 203 being provided with the hinge shaft second mounting holes, and the first hinge portion 120 being located between the two ear plates 203.
The hinge shaft 500 includes a bolt passing through the hinge shaft first mounting hole and the hinge shaft second mounting hole and fixed between the two lugs 203 of the second hinge part by the nut.
The cross section of the tensioning head is oblong or rectangular, and the length direction of the tensioning head is consistent with the length direction of the sunk groove 301 of the first member or the T-shaped groove 401 of the second member during assembly. The long side limits the relative rotation between the two members when the connector 200 is inserted into the T-shaped slot.
The assembly process of invisible connection of two members by using the connecting component is as follows:
as shown in fig. 2 and 4, a groove is formed at an end of the first member 300, a sinking groove 301 is formed at the groove, the fastening member 100 of the invisible connection assembly of any angle is first placed in the first sinking groove 301, the contact surface of the fixing portion is contacted with the groove bottom of the sinking groove 301, and a fastening member 302 (e.g., a screw) is passed through the fastening member mounting hole 111 to fasten the fastening member 100 in the sinking groove 301 of the first member 300. The first hinge portion 120 of the connector 100 and the second hinge portion of the connector 200 are both lower than the tapered surface 303 of the first member, so that when the tensioning head 201 of the connector 200 is inserted from the wide slot end of the T-shaped slot 401, the connection assembly does not interfere with the attachment and locking of the assembly surfaces of the two members.
As shown in fig. 3, a T-shaped groove 401 is opened on one outer surface of the second member 400, and the T-shaped groove 401 has a wide groove end and a narrow groove end.
As shown in fig. 4, when assembling, the bevel surface 303 of the first member 300 is opposite to the outer surface plane 402 of the second member 400, and the assembling angle of the two is α, that is, the opening angle of the bevel, and the angle may be an acute angle or a right angle. Since the plug 200 is hinged to the rigid connection member 100, they can rotate relatively, so that it can adapt to the assembling angle of the two members. The plug connector 200 is pushed into the narrow groove end along the length direction of the T-shaped groove 401, the inner side end surface of the tensioning head 201 is overlapped with the locking end surface of the T-shaped groove 401, and the bevel surface 303 of the first component is attached to and locked with the outer surface plane 402 of the second component.
The width of the tensioning head 201 is matched with the width of the T-shaped groove, so that the plug connector 200 can be inserted from the wide groove end and can generate a guiding effect, and the width of the transition neck 202 is smaller than the width of the narrow groove of the T-shaped groove, so that the plug connector 200 can be inserted into the narrow groove end of the T-shaped groove and then positioned and locked at the narrow groove end.
The invisible connecting structure can be applied to various occasions with aesthetic requirements, is particularly suitable for the furniture industry, preferably adopts plate pieces as the two components, and can be made of engineering plastics without being limited by hardware.
The present invention is not limited to the above embodiments, and all improvements based on the concept, principle, structure and method of the present invention will fall within the protection scope of the present invention.
