Description

Connection structure between plates

The technical field is as follows:

the utility model relates to a connection structure between panel.

Background art:

in some industries where sheet materials are needed, a large number of connecting members are needed to connect and fix two sheet materials together. The more ripe of prior art, the use amount is great is trinity connecting piece, and trinity connecting piece is also known as eccentric connecting piece, comprises eccentric wheel, pole, embedded nut, mainly used plate furniture's connecting piece, embedded nut: special reinforcement; connecting rods: the connection is special; an eccentric head: the problem of locking between the plates is solved. In actual use, the problem of loosening of the three-in-one connecting piece often occurs, and the eccentric head needs to be turned by a screwdriver in assembly and disassembly, so that the three-in-one connecting piece is inconvenient to use. After the furniture is assembled, the eccentric head still can be exposed, so that a large number of eccentric head parts are exposed on the plate of the furniture, and the attractiveness of the furniture is seriously affected.

The utility model has the following contents:

The specific implementation mode is as follows:

the present technology is further described below with reference to the accompanying drawings.

The connection structure between the boards of this embodiment includes a first board a, a second board b, a first board fastening seat 1, a second board fastening seat 2 and a bridging fastener 3, wherein counter bores are formed on the facing surfaces of the first board a and the second board b, fixing fastening edges 5 are formed on the side walls of the two sides in the counter bores, the first board fastening seat 1 is placed in the counter bore 6 of the first board, the second board fastening seat 2 is placed in the counter bore 7 of the second board, the two board fastening seats have the same structure, specifically, the two board fastening seats have a groove-shaped structure with an opening, concave structures 9 are formed on the two sides of the middle part in the opening groove 8, the concave structures 9 are multi-stage ladder structures, elastic fastening edges 4 are formed on the outer side walls of the first board fastening seat 1 and the second board fastening seat 2, when the two board fastening seats are pressed, the elastic fastening edges 4 jump over the fixing fastening edges 5 due to elastic deformation, and finally the elastic fastening edges 4 clamp the fixing fastening edges 5, so that the two plate fastener seats are fixed in the two counter bores 6 and 7. Bridge connection fastener 3's both ends tip structure is the same, both sides at the tip all the shaping have the card limit, bridge connection fastener 31 both sides shaping promptly has first card limit 33, second end 32 both sides shaping has second card limit 34, 8 both sides walls of open slot of two panel buckle seats or bridge connection fastener 3's card limit (be first card limit 33 and second card limit 34) both of them have elastic deformation characteristic, bridge connection fastener 3's first end 31 directly injects first panel buckle seat 1 in, inject the in-process because of elastic deformation, 8 both sides lateral walls of open slot can be skipped to first card limit 33, and finally block the ladder face 91 of first panel buckle seat 1 internal concave structure 9 department, make bridge connection fastener 3 fixed mounting on first panel buckle seat 1, the seat structure is the same basically for two above-mentioned panel buckle seats, because second panel buckle seat 2's open slot 8 has two kinds of structures:

the first method comprises the following steps: as shown in fig. 1 to 6, the first structure is to realize the direct insertion engagement. The structure is the structure described in the above paragraph, when assembling, the first end 31 of the bridging fastener 3 is directly inserted into the first board fastener seat 1 for locking, then the second end 32 of the bridging fastener 3 is also directly inserted into the second board fastener seat 2 for locking, the two locks are operated in a hard insertion mode, the insertion process utilizes the elastic characteristics of the first clamping edge 33 and the second clamping edge 34, so that the first clamping edge 33 jumps over the two side walls of the first board fastener seat open slot 8 and then locks the step surface at the first board fastener seat concave structure 9, the second clamping edge 34 jumps over the two side walls of the second board fastener seat open slot 8 and then locks the step surface 91 at the second board fastener seat concave structure 9, and the direct card-inserting structure is characterized in that the two boards cannot be detached after being clamped, i.e. the clamping is irreversible;

and the second method comprises the following steps: referring to fig. 7 to 12, in the second case, the width of the starting section 81 of the second board fastener seat opening slot 8 is greater than the width distance between the second beads 34 at the two sides of the second end 32 of the bridge fastener, and accordingly, the length of the second end 32 of the bridge fastener is shorter than the length of the starting section 81 of the second board fastener seat opening slot 8, and the structures at other places are not changed, when the bridge fastener is installed, the second end 32 of the bridge fastener is inserted into the starting section 81 of the second board fastener seat opening slot 8 first, at this time, the second beads 34 at the two sides of the second end 32 of the bridge fastener are not locked with the second board fastener seat 2, and then the two boards are pushed to slide with each other, at this time, the second end 32 of the bridge fastener slides into the rear section 82 of the second board fastener seat opening slot 8, so that the second beads 34 are locked with the step surface 91 at the concave structure 9 in the second board fastener seat 2, and the two boards are locked together, this way of first inserting and then pushing the snap-fit sideways is possible to achieve a further detachment, i.e. the snap-fit is reversible.

Of course, the first board fastener seat 1 and the bridging fastener 3 in the present technology can also be an integrally formed structure, and such a structure falls within the scope of the present technology.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. The invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications and variations, including those shown in the drawings and described herein. Therefore, the equivalent changes made according to the shape, structure and principle of the present invention should be covered in the protection scope of the present invention.
