Description

A kind of floor lock button

Affiliated technical field

The utility model relates to a kind of floor lock button constructional device.

Background technology

At present, the floor button of selling on the market comprises that mostly tenon and groove form the snap close of structure, and the weak point of its existence is, at first, has wasted base material, because the complexity of its structure needs the moulding of a large amount of base materials ability of cutting; Secondly, the fastening dynamics is little; The 3rd, cutter consumption required during fluting is many; The 4th, the work dynamic strength of soils is big during assembly unit.

Summary of the invention

Its purpose of the utility model just is a kind of floor lock button is provided, and has simple in structurely, saves base material, the fastening great efforts, and the grooving tool consumption is few, easily the characteristics of assembly unit.

Realize technical scheme above-mentioned and that take, comprise tenon and groove, tenon top is provided with to recessed shape camber line upper buckle side, half garden, the bottom is provided with convex straight line lower buckle side, and the upper buckle side and the outside, lower buckle side are provided with projection, and corresponding tenon upper buckle side, groove top is provided with shape camber line upper buckle side, half garden, corresponding tenon lower buckle side, bottom is provided with the straight line lower buckle side, groove upper buckle side and inboard, lower buckle side are provided with groove, and be narrow outer wide in the described tenon, the outer narrow inner width of described groove.

Compared with prior art this device has the following advantages:

1, owing to adopted the structure design of last lower buckle side, thereby reaches the big purpose of locking force, had the strong characteristics of coupling mechanism force.

2, owing to adopted structure more simply design, thereby have the characteristics of saving base material, and the grooving tool consumption is few.

3,, thereby have the characteristics of easy assembly unit owing to once established the structure design of upper buckle side.

Description of drawings

The utility model is described in further detail for following structure accompanying drawing.

Fig. 1 is this apparatus structure schematic front view;

Fig. 2 is the structural representation of A among Fig. 1;

Fig. 3 is the structural representation of B among Fig. 1.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, comprise tenon A and groove B, tenon A top is provided with to recessed shape camber line upper buckle side, half garden 3, the bottom is provided with convex straight line lower buckle side 5, and the

upper buckle side

3 and 5 outsides, lower buckle side are provided with projection, and corresponding tenon A upper buckle side, groove B top 3 is provided with shape camber line upper buckle side, half garden 4, corresponding tenon A lower buckle side, bottom 5 is provided with straight line lower buckle side 6, groove B

upper buckle side

4 and 6 inboards, lower buckle side are provided with groove, and are narrow outer wide in the described tenon A, the outer narrow inner width of described groove B.

The fastening angle 13 of tenon A and groove B

upper buckle side

3,4 is 35 °-45 °, and the fastening angle 14 of

lower buckle side

5,6 is 30 °-45 °.

Tenon A and groove B positive 1 is seamless spliced, and the back side can be seam 11 splicings.

Tenon A machines away the sub-fraction base material in the front 1 of floor edge and the back side 2 parts, middle remaining base material can form a tenon A, tenon A is designed to the upper and lower surface inner end and falls in to the opposite, and the fovea superior area is long-pending greater than little concave surface, it is wide to make it to become an outer end, the tenon that the inner end is narrow, tenon A fovea superior partial design becomes one and half garden shape camber lines 3, tenon A is provided with a sliding limit 7 of the expansion to 5 directions to the downside outer end, groove part is the opposite side at tenon, a part is waved in the middle base material cutting at the front 1 of floor edge and the back side 2, space with the centre forms a groove, groove B two lateral surfaces are on same vertical line, be that the recess outside maintains an equal level, groove all protrudes to the opposite at base material external port place, both sides up and down, groove has just formed the big shape in the outer space, the narrow inner end of end spaces of a notch, and groove B goes up projection upper buckle side 4 and tenon fovea superior part upper buckle side 3 shapes are identical substantially, just the camber in the middle of the groove upper buckle side 4 is slightly less than the camber of tenon upper buckle side 3, the good formation of splicing cracks 9, groove B inner end spatial altitude has been set up a little groove 10 inwards greater than the base material thickness of tenon A outer end on the lower side at the middle part, space of groove B inner end.

The distance of tenon A upper buckle side 3 and lower buckle side 5 is greater than the distance of groove upper buckle side 4 and lower buckle side 6.Groove upper buckle side 4 rides on the tenon upper buckle side 3 during splicing; it is stressed fulcrum with tenon upper buckle side 3 that groove upper buckle side 4 can be played in tenon upper buckle side 3; and protection groove upper buckle side 4 is difficult for outside landing; groove B lower end is provided with the sliding limit 8 of assembly unit; and be close to the sliding limit 7 of tenon; with the groove upper buckle side 4 that turns clockwise; outwards expand along the sliding limit 7 of tenon simultaneously and slide in the sliding limit 8 of assembly unit; upper end when the sliding limit 8 of assembly unit had moved the lower end on the sliding limit 7 of tenon; 180 ° of the positive one-tenth in two floors; thereby reach tenon lower buckle side 5 and groove lower buckle side 6 are close to mutually; allow groove bottom elastic substrate 12 be in all the time in a kind of upwards state that reduction resets, finally play the purpose that the two places edges of boards connect locking.

Tenon A and groove B splicing, after the locking, inner meeting produces three

slits

9,10,11, its mark sheet makes on two splice floor boards front surface splicing both sides be close to unobstructed mutually now, reach and do not have the requirement of cracking, the requirement that floor two front surfaces are slightly larger than 180 ° also can be satisfied in slit 10,11, thereby guarantees that the polylith floor when splicing both sides can not take place and be upturned.The middle part, space of groove inner end has additional a little groove 10 inwards on the lower side, the base material of a last positive side that it is characterized in that dividing groove is thicker than groove bottom elastic substrate 12, allow groove expand behind the both sides base material interlock tenon up and down, allowing expands only occurs on the groove bottom elastic substrate 12, does not influence the requirement of the difference of height of front surface on the floor thereby reach.

Be passive assembly unit with tenon A during assembly unit, groove B is initiatively assembly unit, pin passive assembly unit plate, catch initiatively one side of assembly unit plate again, ride on the tenon upper buckle side 3 with groove upper buckle side 4 then, the sliding limit 8 of groove assembly unit is close to the sliding limit 7 of tenon, so form initiatively the tenon of the assembly unit plate scope of activities that is no more than 45 that overhead is upturned on one side, then earthward, slightly apply the downward pressure amount to passive assembly unit plate direction, to turn clockwise 4, outwards expand along the sliding limit 7 of tenon simultaneously and slide in limit, groove lower end 8, be moved beyond the lower end on the sliding limit 7 of tenon when the upper end on groove downslide limit 8,180 ° of the positive one-tenth in two floors are close to tenon lower buckle side 5 and groove lower buckle side 6 thereby reach mutually, and assembly unit is finished.
