Connecting hinge for table panel and rear panel support of mahjong table

Abstract

The invention discloses a connecting hinge supported by a mahjong desktop board and a rear panel, which includes an upper hinge and a lower hinge. The upper hinge includes an upper connecting plate on which a plurality of vertically arranged long Strip-shaped waist-shaped holes, each waist-shaped hole is movably connected with the desktop board through connecting bolts, and each connecting bolt and the front and rear sides of the corresponding waist-shaped hole leave a movable gap; the two sides of the back of the upper connecting plate are respectively provided with an upper connection A hinge shaft is arranged between the bottom of the two upper connecting walls; the lower hinge includes a connecting plate, and a connecting wall is provided on both sides of the back of the lower connecting plate, and a connecting wall is provided near the top side of the two connecting walls. In the shaft hole of the hinge shaft, the distance between the outer walls of the two lower connecting walls is smaller than the distance between the inner walls of the two upper connecting walls to form an axial movement gap. The present invention is designed to provide left and right and front and rear small gap adjustments for the installation of the mahjong table top board, which facilitates the actual assembly of the table top board and the back panel support, and has the characteristics of simple and practical structure.

Description

technical field [0001] The invention relates to a mahjong table, in particular to a connecting hinge supported by a mahjong table tabletop and a rear panel. Background technique [0002] At present, for the convenience of overhaul and post-maintenance, the desktop boards on the mahjong table can be rotated and opened towards one side. In the existing structure, its structure is as follows: figure 1 and 2 As shown, the rotation and opening is realized by at least two multi-hinge hinges 1', and the upper hinge 11' of the above multi-hinge hinges 1' is fixedly connected to one side of the desktop board 2' through a plurality of screws 111', and more The lower hinge 12' of the hinge hinge 1' is also fixedly connected with the rear panel support 3' on the side of the mahjong table by a plurality of screws 121', and the rear panel support is connected with the iron plate 4' by a plurality of screws. [0003] Here, the above multi-hinge hinge 1' does not have the function of gap ...

AI Technical Summary

Problems solved by technology

[0003] Here, the above multi-hinge hinge 1' does not have a gap adjustment function, and the upper and lower hinges 11', 12' cannot be adjusted in front, back, left and right.

However, in practice, due to errors in the processing of the rear panel support 3', there are also assembly errors when the desktop board 2' and the rear panel support 3' are assembled. After the multi-hinge hinge 1' is connected to the rear panel support 3' during assembly, it is easy to The fixing hole of the desktop board 2' is offset from the fixing hole of the multi-hinge hinge 1'. At this time, the rear panel support 3' must be manually knocked to correct it. The operation is very troublesome and seriously affects the assembly efficiency of the mahjong table.

[0004] In addition, when the upper hinge 11' of the above multi-hinge hinge 1' rotates about 96° relative to the lower hinge 12', it will stop against the lower hinge 12'. This structure makes the opened desktop board 2' completely suspended , all its weight acts on the multi-hinge hinge 1′, if it is improperly operated or used for a long time, it is easy to cause deformation and damage to the multi-hinge hinge 1′
