Description
Technical Field
The utility model belongs to the technical field of the furniture technique and specifically relates to a structure is inserted tightly fast.
Background
With the development of economy, the living standard of people is gradually improved, the sofa also becomes a piece of common furniture, at present, the armrests and the backrest of the sofa on the market are usually directly connected by fasteners such as bolts or screws and the like,
there is certain clearance after the current structure installation of tightly inserting fast for there is rocking between sofa handrail after the installation and the back, and stability is relatively poor, needs to consolidate through the screw once more, wastes time and energy.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a carry out quick installation and dismantlement, tightly insert the structure and closely cooperate, improve the quick tight structure of inserting of the stability of being connected between sofa handrail and the back.
The utility model provides a technical scheme that its technical problem adopted is: a quick tight-insertion structure comprises a tight-insertion body, wherein the tight-insertion body comprises a first tight-insertion piece and a second tight-insertion piece, one tight-insertion piece is inserted into the other tight-insertion piece, the first tight-insertion piece and the second tight-insertion piece are both in a long strip plate shape with downward gradually reducing, and the first tight-insertion piece and the second tight-insertion piece are in clearance fit; the first fastening plug-in unit and the second fastening plug-in unit both comprise a base plate, and bending portions bent towards the middle of the fastening plug-in units are arranged on two sides of the base plate.
Furthermore, the surfaces of the first clamping piece and the second clamping piece are provided with mounting holes and adjusting holes.
Further, the first fastening-inserting piece is installed on the backrest of the sofa, and the second fastening-inserting piece is installed on the armrest of the sofa; or the first fastening piece is arranged on the armrest of the sofa, and the second fastening piece is arranged on the backrest of the sofa.
Furthermore, the cross section of the bending part is in a cross section shape of < shape.
Further, the range of clearance fit between the first and second fastener elements is 0-1 mm.
Furthermore, the length of tightly inserting the body is 180mm, in order to improve the steadiness of tightly inserting the body, prevent to influence the steadiness because length is too little, and length is too long and the resource is wasted, improves economic nature.
The utility model has the advantages that: the utility model discloses simple structure can carry out quick installation and dismantlement, tightly inserts the structure and closely cooperates, does not have gapped existence, improves the stability of being connected between sofa handrail and the back, and labour saving and time saving.

The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a perspective view of embodiment 1 of the present invention;
fig. 2 is a usage state diagram of embodiment 1 of the present invention;
in the figure: 11. a first fastener, 12, a second fastener, 13, a mounting hole, 14, an adjusting hole, 15, a base plate, 16, a bent portion,
Detailed Description
The present invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Example 1:
as shown in fig. 1-2, a quick tight-inserting structure comprises a tight-inserting body 1, wherein the tight-inserting body 1 comprises a first tight-inserting piece 11 and a second tight-inserting piece 12, one of the tight-inserting pieces is inserted into the other of the tight-inserting pieces, the first tight-inserting piece 11 and the second tight-inserting piece 12 are both in a long-strip plate shape tapering downward, and the first tight-inserting piece 11 and the second tight-inserting piece 12 are in clearance fit; the first fastening plug-in unit 11 and the second fastening plug-in unit 12 both comprise base plates 15, bending parts 16 which are bent towards the middle of the fastening plug-in units are arranged on two sides of each base plate 15, and the cross section of each bending part 16 is in a cross shape of < on.
The plate surfaces of the first fastening piece 11 and the second fastening piece 12 are provided with mounting holes 13 and adjusting holes 14, the first fastening piece 11 is mounted on the backrest of the sofa, and the second fastening piece 12 is mounted on the armrest of the sofa;
the range of clearance fit between the first tight inserting piece 11 and the second tight inserting piece 12 is 0-1 mm, and the length of the tight inserting body 1 is 180mm.
The installation process comprises the following steps:
as shown in fig. 2, the first sub-body 11 is installed on the side of the backrest of the sofa, and the second sub-body 12 is installed slantingly on the side of the armrest of the sofa.
When the sofa armrest is installed, the sofa armrest is lifted, the bent part 16 of the second split body 12 is aligned with the bent part 16 of the first split body 11, and the sofa armrest is inserted into the first split body 11, so that the installation between the sofa armrest and the backrest can be completed, at the moment, a gap is basically not formed between the first split body 11 and the second split body 12, so that a large shaking feeling cannot be generated between the first split body 11 and the second split body 12, the inner surface of the bent part 16 of the first split body 11 is attached to the outer surface of the bent part 16 of the second split body 12, and the installation between the sofa armrest and the backrest is completed.
When the sofa armrest is detached, the sofa armrest can be conveniently and quickly separated from the backrest only by lifting the sofa armrest upwards and separating the second sub-body 12 from the first sub-body 11.
Example 2:
the difference from example 1 is that: the first fastener piece 11 is mounted on the arm of the sofa and the second fastener piece 12 is mounted on the back of the sofa.
While the foregoing description describes only certain embodiments of the invention, it is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
