Description

A kind of Collapsible rack double locking member

Technical field

The utility model is related to a kind of Collapsible rack locking device, to ensure the stability after Collapsible rack expansion.

Background technology

The desktop of conventional tables is typically to use an integrally-built desktop, therefore strong by manufacturing process, desktop The limitation of degree etc., desktop tends not to do too much.And in order to meet the needs of market is to big specification desktop, using double desktops Harden structure solves the problems, such as this, and by configuring two Collapsible racks in desktop bottom, make two desktops not only can folding, but also Stent can be hidden in two desktops after combining.

Common Collapsible rack, for tool there are one U-shaped feet, the upper end passes through shaft and the bottom surface phase of desktop Even, and supporting item is provided between desktop and feet, which is articulated by one end, jointly in the distribution of Y types Three-link forms, and wherein two middle side parts of the other end of first connecting rod, second connecting rod respectively with U-shaped feet are hinged, and the 3rd It is hinged in the middle part of the other end of connecting rod and the bottom surface of desktop.And three-link folding in order to prevent, in the three-link Articulated section is cased with slidable blocker ring.But there are the problem of to be such blocker ring easily unclamp if not lockking and slides, because This depends merely on blocker ring to lock three-link, can't ensure the stability after stent expansion completely.

The content of the invention

First technical problem to be solved in the utility model is present situation for the above-mentioned prior art, provides a kind of structure The Collapsible rack locking device being simple and convenient to operate, it combines the blocker ring on former stent, to stent double locking, it is ensured that It supports, eliminates safe hidden trouble reliable and stablely after stent expansion.

Technical solution is used by the utility model solves above-mentioned technical problem：A kind of Collapsible rack double locking dress Tool is put there are one generally U-shaped supporting rack, the upper end can be turned back by shaft with respect to panel, and between panel and supporting rack Be provided with supporting item, which is articulated jointly by one end, the three-link that is distributed in Y types forms, wherein first connecting rod, The other end of second connecting rod is hinged respectively with two middle side parts of U-shaped supporting rack, and the other end of third connecting rod is rotatably connected On the suitable position of panel bottom, and slidable blocker ring is cased in the articulated section of the three-link, it is characterized in that Neighbouring three-link hinged place, a /V catch is also hinged on the first connecting rod or second connecting rod, works as Collapsible rack During opening, the /V catch is close to behind the end of the third connecting rod or the /V catch and described the The end of three-link is mutually hit against.

The /V catch can be designed to " L " shapes.

Compared with prior art, the utility model has the advantage of：One is added again on the basis of original Collapsible rack /V catch, the rotary spacing catch when Collapsible rack is opened, makes the third connecting rod of itself and stent mutually hit against, and limitation the 3rd connects Bar is turned back；As long as the then rotary spacing catch when Collapsible rack is folded, makes it no longer stop third connecting rod；Thus Simple in structure, easy to use, it combines the blocker ring on former stent, to stent double locking, it is ensured that reliable steady after stent expansion Surely support, eliminate safe hidden trouble.

Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing embodiment.

Reference Fig. 1-Fig. 4, to be equiped with the folding table of the Collapsible rack double locking member according to the utility model, Mainly include by the identical left/right panel of two sizes, shape, be separately fixed at left/right panel bottom left and right frame, with The two movable Collapsible racks folded that left and right frame is connected, and connection cross bar 1 is equipped at left/right panel docking, Left and right frame includes the connection montant 4 being mutually parallel, and is separately fixed at the both sides of left/right panel bottom, two connection montants Shaft 6 is rotatably provided between 4.Wherein, hollow blow molding panel, but desktop, desktop bottom may be employed in left/right panel Frame structure not /V the present embodiment figure shown in scheme, can retrofit or using other well known technology.

Described Collapsible rack tool is there are one generally U-shaped supporting rack 5, and upper end and corresponding above-mentioned shaft 6 It mutually welds so that supporting rack 5 is rotated compared with desktop.In order to make energy support desk panel after above-mentioned supporting rack rotates, in desktop Supporting item is respectively arranged between plate and supporting rack, the three-link which by one end is articulated, is distributed in Y types jointly Composition, wherein first connecting rod 3, the other end of second connecting rod 8 are hinged respectively by two middle side parts of axis pin and supporting rack 5, and The other end of third connecting rod 9 is sleeved on connection cross bar 1, can be rotated around connection cross bar 1.Certainly tied according to the difference of desktop bottom Structure, the other end of third connecting rod 9 are also attached on different components, such as fix a fixed seat, third connecting rod in desktop bottom The other end can be also connected with the fixed seat by pin so that it can be rotated compared with desktop, be not limited to this reality in a word Apply the embodiment of example.

And support desk panel can be consolidated after being opened in order to ensure above-mentioned Collapsible rack, except in above-mentioned three-link 3,8,9 Articulated section be cased with it is slidable, for preventing outside the blocker ring 2 of three-link folding, in neighbouring three-link hinged place, described Also there is a /V catch 7 by pin hinges on first connecting rod 3 or second connecting rod 8, which can be implemented with design cost " L " shape of example, so can further limit the inadvertently folding of third connecting rod 9 by the /V catch 7.Specifically, After Collapsible rack is opened, rotary spacing catch 7 makes it go to behind the end of third connecting rod 9 and offset on one side to touch (such as Fig. 5 It is shown), naturally it is also possible to be do not collide but adjacent relation can also, can also reach same effect；It can be rolled over when wanting folding During folded stent, then /V catch 7 is rotated further by, releasing it can (as shown in Figure 6) to the stop of third connecting rod 9.This /V catch Setting do not influence the folding of entire Collapsible rack, design is simple, rationally, effectively ensures reliable and stable after stent is opened Ground supports, and eliminates safe hidden trouble, promotes the quality of entire folding table.
