Problems solved by technology

[0002]The existing furniture assembly connectors are generally two-in-one, three-in-one eccentric parts that are directly tightened or embedded in positioning and tightened. The main disadvantages are: (1 ) There are many assembling procedures for furniture, which are cumbersome and inefficient. For example, the most commonly used three-in-one (glue seat, screw, eccentric lock cap) disassembly and assembly parts not only need to drive the screw rubber seat on the surface of the board, but also need wooden pins to cooperate. Positioning; while there are many drilling processes for furniture panels, especially for embedded positioning connectors, the drilling process of panels is complex and precise positioning is required; (2) The screw is screwed into the rubber seat too deep or too shallow, which is prone to eccentricity The nut cannot be hooked to the screw head, resulting in the situation that it cannot be locked; (3) The tightening method causes the lock to be unstable and shakes, and the assembled furniture must be fixed separately; if the backboard is fixed with screws, it can be placed independently; ( 4) The exposed eccentric nut hole of the plate is large and unsightly; (5) The cost of use is high

Embodiment 1

[0025] Embodiment 1: Fast assembly connector structure for multifunctional furniture

[0026] see Figure 1 to Figure 10 :

[0027] The fast assembly connector for multifunctional furniture consists of two parts, the outer expansion sleeve A and the built-in movable push rod B.

[0028] The outer expansion sleeve is divided into a base 1 and an insertion section 2 with a diameter slightly smaller than the base; the end of the base is an expansion point 3-1, and the insertion section is provided with two expansion points 3-2 and 3-3 Each expansion point is provided with several expansion sheets 4; the built-in movable push rod is provided with hammer heads 5 corresponding to the number of expansion points.

[0029] The opening direction of the expansion piece 4-2 at the expansion point 3-2 in the middle of the insertion section of the outer expansion sleeve is consistent with the opening direction of the base expansion piece 4-1, and is designed in an inner arc. When it expan...

Embodiment 2

[0034] Example 2: 90° right-angle connection without disassembly of the panels

[0035]In this embodiment, the base hole 13 is first punched on the surface of the vertical furniture board H, the insertion hole 14 is punched at the side end of the horizontal furniture board D, and the T-shaped head 8 end of the movable push rod of the connector is punched in the base hole of the outer expansion sleeve. until the tapered hammer head 5-2 in the middle of the push rod enters its positioning area 7 in the casing, the T-shaped head 8 of the push rod extends out of the tail end of the casing, and the dome gasket 9 is put on to complete the assembly of the finished connector , put the base section 1 of the connector into the base hole 13 on the surface of the vertical plate H, exposing the insertion section 2, and the base positioning cylinder section 1-2 is closely matched with the hole wall to keep the connector stable; press down the movable push rod T by hand Squeeze the hammer he...

Embodiment 3

[0036] Example 3: Detachable 90° right-angle connection

[0037] The difference from Embodiment 2 is that a removal hole 15 is added at the bottom of the insertion hole 14 at the corresponding side end on the surface of the horizontal furniture board D, and the hole diameter is equal to or slightly smaller than the insertion hole, so that the detachable 90° right-angle connection of the furniture board can be realized , after the furniture panels are assembled, the dismounting hole 15 can be covered with a decorative cover 10 . When the board needs to be disassembled, remove the decorative cover 10, use the special hook 11 to hook out the dome gasket 9 on the T-shaped head 8 of the movable push rod of the connector, make room for a certain space, and insert the Y-shaped special tool 12 into the disassembly hole 15 Inside, pry the T-shaped head 8 to loosen and retreat, and complete the disassembly of the board.

Abstract

A multifunctional connecting piece for quickly assembling furniture consists of an outer-layer expandable sleeve and a built-in movable push rod. The outer-layer expansion sleeve includes a base and an inserting section with diameter smaller than the base. The base includes an end expansion section and a base positioning section. An expansion point is arranged at the end expansion section, and a plurality of expansion pieces are arranged on the expansion point. Two to five expansion points are arranged at the inserting section, wherein the tail end is an expansion point, one to four expansionpoints are arranged at the middle of the inserting section, and a plurality of expansion pieces are arranged on each expansion point. The built-in movable push rod is provided with cone-shape hammerssame as the expansion points in number. The multifunctional connecting piece integrates a positioning function and a fastening function, can used for connecting furniture plates at 90-degree right angle or in a 180-degree straight line mode, and can used for detachable connection and non-detachable connection. Assembly efficiency of the furniture plates is high, and the furniture plates are connected and locked firmly and stably. After the plates are connected, the appearance is natural and attractive and free of exposed holes and screw heads, the structure is simple, and using cost is low.
