Abstract

The utility model discloses a kind of plug assembly, it comprises base, inserted link, spring, snap ring, socket.Described inserted link activity is plugged in the slot of base, and snap ring is connected in the draw-in groove in the middle part of plunger body and between two slots, spring housing is connected on the body of inserted link.Because the projection end of the utility model inserted link inserts in receptacle sockets, holding inserted link can be fixed firmly in the jack of socket on the cascaded surface of receptacle sockets after projection half-twist, inserted link can not be separated with socket, connect very firm.

Description

Plug assembly

Technical field

The utility model relates to a kind of latch, particularly relates to a kind of plug assembly.

Background technology

Latch is a kind of simple components preventing door from opening, and is generally metal, point two parts, and a part is with mobilizable bar, and a part is a socket.The partial fixing of usual band bar is on door, and socket is fixed on doorframe, and position will be corresponding to.During use, bar is inserted in socket.In foldable children bed, also use latch as the use of the connection between bed board, bedside rails, cabinet base, but the top tube head of the latch in this traditional foldable children bed is sharp or level and smooth, may easily try to shirk responsibility because the reason such as to rock when reality uses, be separated between bedside rails with bedside rails, between bed board with bedside rails, between bedside rails with cabinet base, cause folding bed unstable, unsafe factor served by band.

Utility model content

The purpose of this utility model is to provide a kind of plug assembly be connected firmly.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of plug assembly, and it comprises base, inserted link, spring, snap ring, socket; Described base is made up of base plate, two slots and two pieces of baffle plates; Described base plate side is provided with two slots, and two slot intervals arrange and are positioned on same axis, and one end of base plate is installed with two pieces of baffle plates vertically upward, and two pieces of baffle intervals are arranged, between two pieces of baffle plates, form draw-in groove; One end bent outward of described inserted link is converted into L shape, and the other end of inserted link has a projection extended radially outward, and plunger body activity is located in two slots of base; In the draw-in groove that described snap ring is connected in the middle part of plunger body and between two slots, spring housing is connected on the body of inserted link, one end of spring leans on the inner face of inner slot, and the other end of spring leans on snap ring; Described socket has a jack, and this jack is a shoulder hole, and the aperture of shoulder hole is from increasing step by step outside to inside; One end that described inserted link has projection penetrates in the jack of socket, and after projection half-twist, inserted link fixes in the jack of socket by holding on the cascaded surface of receptacle sockets, and the L shape bending end of inserted link can in the draw-in groove of holding on base between two pieces of baffle plates.

Lateral dimension on described inserted link projection cross section is less than longitudinal size; Lateral dimension on the cross section of receptacle sockets exit orifice be less than longitudinal size and with the appearance and size matched in clearance of inserted link projection.

After adopting such scheme, because one end of the utility model inserted link has projection, this projection penetrates the jack of socket, can holding be fixed firmly by inserted link in the jack of socket on the cascaded surface of receptacle sockets after projection half-twist, inserted link can not be separated with socket, connect very firm.

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Detailed description of the invention

As shown in Figure 1, the utility model is a kind of plug assembly, and it comprises base 1, inserted link 2, spring 3, snap ring 4, socket 5.

As shown in Figure 1 and Figure 2, described base 1 is made up of base plate 11, two slots 12,13 and two pieces of baffle plates 14,15.Described base plate 11 side is provided with an inner slot 12 and an outer slot 13, two slot 12,13 intervals arrange and are positioned on same axis, one end of base plate 11 is installed with two pieces of baffle plates 14,15 vertically upward, two pieces of baffle plate 14,15 intervals are arranged, between two pieces of baffle plates 14,15, form draw-in groove 16.

One end bent outward of described inserted link 2 is converted into L shape, and be L shape bending end 21, the other end of inserted link 2 has a projection extended radially outward 22, and the activity of inserted link 2 body is located in two slots 12,13 of base 1.Described snap ring 4 to be connected in draw-in groove in the middle part of inserted link 2 body 23 and when assembling between two slots 12,13; Spring 3 is socketed on the body of inserted link 2, and one end of spring 3 leans on the inner face of inner slot 12, and the other end of spring 3 leans on snap ring 4.

Described socket 5 has a jack 51, and this jack 51 is a shoulder hole, and the aperture of shoulder hole is from increasing step by step outside to inside, and outer end is aperture 511, the inner is macropore 512.

During use, one end that described inserted link 2 has projection 22 penetrates in the jack 51 of socket 5, again by inserted link 2 half-twist, inserted link 2 fixes in the jack 51 of socket 5 by projection 22 holding after half-twist on the cascaded surface 52 of socket 5 jack 51, meanwhile, in the draw-in groove 16 of L shape bending end 21 holding of inserted link 2 on base 5 between two pieces of baffle plates 14,15.

Shown in composition graphs 3, Fig. 4, Fig. 5, in order to the jack 51 preventing the projection 22 on inserted link 2 from deviating from socket 5, when designing, the lateral dimension on described inserted link 2 projection 22 cross section is less than longitudinal size; Socket 5 jack 51 aperture 511(exit orifice) cross section on lateral dimension be less than longitudinal size and with the appearance and size matched in clearance of inserted link 2 projection 22.

In the present embodiment, projection is the cylinder after both sides are scabbled.Projection also can be petal-shaped, and accordingly, the jack on socket is also in petal-shaped.

As shown in Figure 6, Figure 7, on foldable children bed, bed board 10 and bedside rails 20 by the utility model plug assembly in conjunction with schematic diagram.

Emphasis of the present utility model is just: inserted link one end is provided with projection.

The above, be only the utility model preferred embodiment, the shape of projection can have multiple, therefore the scope of the utility model enforcement can not be limited with this, namely the equivalence change done according to the utility model claim and description with modify, all should still belong in scope that the utility model patent contains.
