Abstract

The utility model relates to a locking mechanism used on furniture. The locking mechanism comprises a fixed plate, a rotating plate, a lock tongue, a torsion spring and an unlocking rod. The fixed plate is provided with a rivet nut locking hole, a rivet pin locking groove, a lock tongue sliding groove which is matched with the rivet pin locking groove, an unlocking through groove which penetrates through the lock tongue sliding groove, a torsion spring positioning pin and a torsion spring positioning groove; a rivet nut and a rivet pin are arranged at the two ends of a rotating plate body; an unlocking rod installation hole and a torsion spring positioning hole are arranged on the lock tongue; the torsion spring is sheathed on the torsion spring positioning pin, one end of the torsion spring is arranged in the torsion spring positioning groove on the fixed plate, and the other end of the torsion spring is sheathed in the torsion spring positioning hole on the lock tongue in an inserting manner; the lock tongue is arranged in the lock tongue sliding groove of the fixed plate, and the unlocking rod is fixed in the unlocking rod installation hole of the lock tongue by penetrating through the unlocking through groove. The locking mechanism can reduce transportation cost without installation by clients, thus avoiding complaints due to the clients cannot assembly products after buying; moreover, the locking mechanism is firm, the intensity is high and the utilization is convenient.

Description

Be used for the locking framework on the furniture

Technical field:

The utility model relates to the furniture technical field, more specifically to the seat, the backboard locking framework that are used on the furniture.

Background technique:

In modern furniture was made, a particularly big furniture for the ease of transporting and moving, generally all was to be designed to removably, and for reaching this purpose, some office chairs all are the bindiny mechanisms that adopts hook-shaped or bolt-type structure on the market.Its deficiency is not located, and 1, bindiny mechanism's intensity difference of hook-shaped or bolt-type structure; 2, bindiny mechanism hook-shaped or the bolt-type structure needs the client to install voluntarily according to product descritption, after some client buys back, can not install and can complain product, brings the prestige infringement to producer, uses extremely inconvenient.

The model utility content:

The utility model is exactly at above-mentioned hook-shaped or bindiny mechanism's intensity difference of bolt-type structure, the deficiency that needs the client to install voluntarily, and a kind of locking framework that is used on the furniture is provided.It has been removed the client from and has installed voluntarily, and product strength is firm.

Technology solution of the present utility model is as follows:

Be used for the locking framework on the furniture, comprise fixed plate 1, swivel plate 2, dead bolt 3, torsion spring 4, trip lever 5;

Fixed plate 1 has Insert Nut locking aperture 11, riveting pin locking slot 12, the dead bolt sliding-groove 13 that matches with riveting pin locking slot 12, penetrates release groove 14, torsion spring locating stud 15, the torsion spring locating slot 16 of the moving groove 13 of dead bolt bone;

Swivel plate 2 has Insert Nut 22, riveting pin 23 for two ends at plate body 21;

Have trip lever mounting hole 31, torsion spring positioning hole 32 on the pin tongue 3;

Torsion spring 4 is enclosed within on the torsion spring locating stud 15, and an end of torsion spring 4 places the torsion spring locating slot 16 on the fixed plate 1, in the torsion spring positioning hole 32 of the other end sleeve on dead bolt 3;

Dead bolt 3 is installed in the dead bolt sliding-groove 13 of fixed plate 1, and trip lever 5 passes in the trip lever mounting hole 31 that release groove 14 is fixed on dead bolt 3.

The top of described dead bolt sliding-groove 13, torsion spring locating stud 15, torsion spring locating slot 16 is fixed with cover sheet 6.

Described cover sheet 6 has riveting post 61, and cover sheet 6 is riveted in the cover sheet rivet hole 17 on the fixed plate 1 that cooperates with cover sheet 6.

The beneficial effects of the utility model are:

1, it is widely used on Office furniture and the Home furniture, because whole chair packaging volume is big, the utility model can make some furnitur manufacturers can reduce packing cost, reduces cost of transportation, makes product have more the power of striving unexpectedly.

2, it can remove client's installation from, avoids product to buy back the complaint of can not adorning and causing the client, adopts the office chair client of this mechanism design only need gently put forward back pad and one pushes away back pad and automatically lock backward.

3, locking framework intensity of the present utility model is firm, and avoiding on the market some office chairs to adopt collapsible all is some bindiny mechanism's intensity differences hook-shaped or the bolt-type structure, uses inconvenient.

Embodiment:

See shown in Fig. 1～6: be used for the locking framework on the furniture, comprise fixed plate 1, swivel plate 2, dead bolt 3, torsion spring 4, trip lever 5;

Working principle and mounting type, dead bolt 3 is installed in the dead bolt sliding-groove 13 in mechanism's fixed plate 1, and screw-in trip lever 5, and torsion spring 4 is fixed in the torsion spring fixing pin 15, and with an end torsion spring as for torsion spring locating slot 16, the other end is caused torsion spring positioning hole 32 on dead bolt, pulling trip lever 5 in back is installed, check the dynamics and the elasticity of dead bolt 3 and torsion spring 4.And cover sheet 6 is buckled in the cover sheet rivet hole 17 in mechanism's fixed plate 1.

With the pivot point hole on the swivel plate 2 upper end Insert Nuts 22 insertion mechanism fixed plates 1, and lock screw 7, and be fulcrum with the upper end Insert Nut, and rotate and to touch dead bolt 3 when riveting pin 23 on the swivel plate 2 imports rotational lock grooves 12, when running into external pressure, dead bolt 3 upwards slides, this moment, torsion spring 4 two ends produced torsion, produce after torsion spring 4 pressure relieves when riveting pin 23 on the swivel plate 2 imports riveting pin locking slot 12 locking bits reset response " clickly " a sound lock tongue 3 slips into, dead bolt 3 blocks the riveting pin 2 on the swivel plate 2.Remove 3 need of dead bolt with up pull-up of trip lever 5, the riveting pin 23 on the swivel plate 2 is removed the shelves thing and can be produced, and dead bolt 3 automatically resets by the pressure of torsion spring 4.
