Abstract

The utility model discloses a connection box and a joint device thereof, which are used for the installation in the building or the electric appliance circuit, comprising a connection box, a transfer joint, an anti-seepage cushion ring, a wire bolt pipe, etc. When the wiring needs carrying out in the construction, the wire bolt pipe is sheathed into the transfer joint and fixed on a device through bolts; the transfer joint is sheathed with the anti-seepage cushion ring and then embedded into the connection box and rotated in an angle, and the transfer joint and the connection box can be tightly clamped and fixedly sheathed. The utility model has the advantages of simple structure, easy fabrication, convenient assembly, low cost, labor saving, time saving, stable and fast scarf joint, and beautiful wiring.

Description

Connection box and quick joint thereof

Terminal box and piecing devices thereof that the utility model belongs in the building or installs and uses in the electric appliance circuits.

At present, in house service, the wiring of decoration formula of residential housing and office block, the fast-wiring that electrical equipment is installed in the factory often adopts various wire casings or keeps somewhere the circuit mouth in advance, utilizes the bolt lock tube, but need bury underground in advance before the fill water cement concrete.Its circuit mouth also must be with re-laying cement concrete behind the screw locking, its moisture content can be invaded wire casing inside or connection jaws, and it is stuck that thread is got rusty, can't breakdown when causing wiring, and electric wire is moist easily, also cause loose contact, when wire casing is constructed, also necessary online crossing tapping one by one, take a lot of work, time-consuming, easy damaged in collision when handling and loading, both uneconomical, inconvenient again.

The purpose of this utility model, it is shortcoming at above wiring construction, a kind of thread locking that structurally do not need is provided, but adopt novel terminal box and anodontia snap joint, make it both have tight kayser function, have certain good waterproof effect again, be a kind of simple in structure, easy to process, install fast, cost is low, economical and practical, wiring wiring attractive in appearance is closed and snap joint.

The utility model is achieved in that a kind of novel terminal box of design and anodontia snap joint.On the surface of terminal box box body, be shaped on circular hole, and be shaped on two embeded slots of symmetry in circular hole periphery both sides.Adapter coupling is a hollow cylinder, is shaped on and the corresponding convex clamping point of embeded slot in its head end cylinder outer surface upper and lower position, is shaped on gasket groove near the convex clamping point rear side.After embedding in the circular hole of terminal box behind the adapter coupling suit antiseepage packing ring, rotating an angle position, just can closely fix socket, to reach the purpose of waterproof.Be shaped on integrated convex ring body at the adapter coupling cylinder outer surface again, and above convex ring body, be shaped on two and penetrate screw.When circuit is installed, need only earlier line bolt pipe box be gone in the adapter coupling, again bolt is screwed in screw, it is installed, and then, rotate a position embedding in the terminal box behind the adapter coupling suit antiseepage packing ring, can closely fix socket, to reach the purpose of quick socket.If when connecing not wiring of box, can connect a stopper.To avoid interface to damage.

The utility model is described in further detail below in conjunction with description of drawings and embodiment:

1--terminal box 2--adapter coupling 3--antiseepage packing ring 4--line bolt pipe

10--circular hole 11--embeded slot 12--convex clamping point 22--convex ring body

23--screw 24--bolt 30--gasket groove

To shown in Figure 3, make a cuboid terminal box 1 and members such as the quick adapter coupling 2 of anodontia, antiseepage packing ring 3 by Fig. 1.Be shaped on circular hole 10 on the upper surface of cuboid terminal box 1 and side surface, each surface is gone up and can be made 1 to 4 circular hole 10, and is shaped on two symmetrical embeded slots 11 in circular hole periphery both sides, and embeded slot 11 can be arc groove or square groove.Adapter coupling 2 is a hollow cylinder, in cylinder front end outer surface upper and lower position, be shaped on and embeded slot 11 shapes and all corresponding convex clamping point 21 of size, rear side near convex clamping point 21 is shaped on gasket groove 30, be shaped on integrated convex ring body 22 at cylinder outer surface again, and above adapter coupling 2 rear end convex ring bodies 22, be shaped on two and penetrate screw 23, when embedding behind the adapter coupling 2 suit antiseepage packing rings 3 in terminal box 1 circular hole 10, just can closely fix socket after rotating an angle position, to reach the waterproof purpose.

If during terminal box 1 not wiring, a stopper can be installed, to avoid interface to damage, when distribution is installed circuit if will construct, only need earlier line bolt pipe 4 to be inserted in the adapter coupling 2, again bolt 24 is screwed in screw 23, it is installed, and then adapter coupling 2 suit waterproof washers 3 back embedded in the circular hole 10 of terminal boxes 1, rotate an angle position after, can closely fix and connect cover.Otherwise, if will dismantle adapter coupling 2 time, then only need counter-rotating, make convex clamping point 21 on the adapter coupling 2 break away from the box body of terminal boxes 1, can reach fast and convenient dismounting.(referring to Fig. 4)

In sum, the utility model terminal box and snap joint thereof, owing on adapter coupling 2, be shaped on convex clamping point 21, on terminal box 1, be shaped on embeded slot 11 mutual build-ins and cooperate, changed traditional thread locking, not only simple in structure, and interlocking is firm, easy to process, and installation and removal all easily and fast, with low cost, save time, the saving of labor, economical and practical.Owing to the front end sleeve at adapter coupling 2 is equipped with antiseepage packing ring 3, not only make adapter coupling 2 can't throw off terminal box 1 again, and sealing, can reach waterproof, damp-proof effect.Also, during as if not wiring, a stopper can be installed because adapter coupling 2 of the present utility model can be installed different line bolt pipes 4, in case the interface damage, so quite practical, and it is attractive in appearance to connect up.
