Technical field

The utility model relates to a kind of furniture, is specifically related to a kind of removable sofa.

Background technique

In the modern life, sofa is the furniture of household indispensability.Because sofa size is larger, all-in-one-piece sofa is unfavorable for carrying, limit by the corridor of house and door opening, affect the travelling comfort of sofa, so market there is detachable sofa, can guarantee that sofa has larger size, ensure travelling comfort, also convenient carrying, original assembly process completed in factory is changed into and directly installs in field of employment, but existing detachable sofa is undertaken affixed by fastening pieces such as bolts when mounted, specific instrument is needed during dismounting, and the fastening piece after breaking easily is lost, impact is assembled again, inconvenience is brought to user.

Model utility content

In order to solve the deficiencies in the prior art, the utility model provides a kind of sofa with integrated type fast assembling disassembling structure, both easy disassembly, also avoids the situation losing fastening piece to occur.

The utility model realizes in the following manner: a kind of sofa with integrated type fast assembling disassembling structure, comprise sofa frame, the cushion being wrapped in the external member on sofa frame and being placed in external member, some cross bars that described sofa frame comprises two symmetrically arranged stiles and is connected between described stile, described cross bar two ends are equipped with integrated type fast assembling disassembling structure, described fast assembling disassembling structure comprises a fixing part and being located at cross bar end face and is connected to movable latch on described fixing part, the end of described cross bar is through the mounting hole be located on described stile, and located by described latch.Be integrated type bolt connection structure by the linkage structure between cross bar and stile by original fastening piece Innovation of Connection, whole disassembly process is made only to need free-hand completing, without the need to preparing particular tool, effectively can also solve the problem of breaking rear fastening piece loss impact and again assembling, after breaking, movable latch still hangs on fixing part, guarantees the next time of assembling smoothly.The two ends of cross bar are all fixed on two lateral vertical frames by integrated type fast assembling disassembling structure.

As preferably, be provided with inside described crossbar end with described stile inside the mounting hole edge step surface of conflicting, the distance between described step surface with described fixing part is mated with described mounting hole hole depth.Crossbar end is through after the mounting hole of stile, and step surface is conflicted on the forward surface of stile, and coordinates the object realizing gripping stile with latch.

As preferably, described latch is strip, its connecting end is provided with a strip and wears groove, described fixing part is the latch closure of a band positioning hole, described latch by it wear groove movably articulating on described positioning hole, described latch with described latch closure for axle switches laterally placing between state and vertical stationary state.When latch is in and laterally places state, latch and the cross bar of strip are located along the same line, convenient overall through described mounting hole, when latch is in vertical stationary state, latch utilizes long limit, its side to conflict in the side dorsad of stile, and coordinates with the step surface on cross bar and grip stile; Wearing groove for latch closure provides activity space, and latch is all connected with latch closure when laterally placing state, vertical stationary state or being in both switching states.

As preferably, described flute length sidewall and the long sidewall of described latch worn is for be arrangeding in parallel, and form straight line active section, the end face of described latch connecting end and the described end face of groove near described connecting end of wearing are all in being arc, and forming arc active section, the thickness of described straight line active section and arc active section is all less than described positioning hole aperture.When latch is in vertical stationary state, described straight line active section, for the formation of the resistance surface with stile side dorsad, improves join strength and stability by increasing conflict area; Arc active section can guarantee latch laterally place switch between state and vertical stationary state time smoothly by the positioning hole on latch closure, realizing latch laterally placing between state and vertical stationary state changes.

The beneficial effects of the utility model: be integrated type bolt connection structure by original fastening piece Innovation of Connection by the linkage structure between cross bar and stile, whole disassembly process is made only to need free-hand completing, effectively can also solve the problem of breaking rear fastening piece loss impact and again assembling, after breaking, movable latch still hangs on fixing part, guarantees the next time of assembling smoothly.

Embodiment

Below in conjunction with specification drawings and specific embodiments, substantive distinguishing features of the present utility model is further described.

A kind of sofa with integrated type fast assembling disassembling structure as shown in Figure 1, by sofa frame, be wrapped in the external member 1 on sofa frame and the cushion 2 be placed in external member 1 forms (as Fig. 7, shown in 8), some cross bars 4 that described sofa frame comprises two symmetrically arranged stiles 3 and is connected between described stile 3, described cross bar 4 two ends are equipped with integrated type fast assembling disassembling structure, described fast assembling disassembling structure comprises a fixing part and being located at cross bar 4 end face and is connected to movable latch 5 on described fixing part, the end of described cross bar 4 is through the mounting hole 6 be located on described stile 3, and located by described latch 5, described cross bar 4 tip inside be provided with described stile 3 inside the mounting hole 6 edge step surface 7 of conflicting, described step surface 7 mates with described mounting hole 6 hole depth with the distance between described fixing part, described latch 5 is in strip (as shown in Figure 2), its connecting end is provided with a strip and wears groove 9, described fixing part is the latch closure 8 in a band articulating hole 10, articulating is on described articulating hole 10 (as shown in Figure 6) movably by the groove 9 of wearing on it for described latch 5, and described latch 5 is that axle is laterally placing state and vertically switching between stationary state with described latch closure 8, the described long sidewall of groove 9 and the long sidewall of described latch 5 worn is for be arrangeding in parallel, and form straight line active section, the end face of described latch 5 connecting end and the described end face of groove 9 near described connecting end of wearing are all in being arc, and forming arc active section, the thickness of described straight line active section and arc active section is all less than aperture, described articulating hole 10.

In practical operation, the both sides orifice edge of described stile 3 mounting hole 6 is burnishing surface, is respectively used to conflict step surface 7 and latch 5 straight line working part.

In practical operation, realize sofa assembling by following steps:
