Detailed description of the invention

As depicted in figs. 1 and 2, a kind of hollow foot that the utility model one embodiment provides, comprises two fixed blocks be oppositely arranged 10 and two insertion blocks 20 be oppositely arranged.The inner surface 100 of fixed block 10 and the inner surface 200 of insertion block 20 enclose formation one cavity 101 jointly.

In embodiment shown in figure, the cross section of fixed block 10 and insertion block 20 is square, and is in particular rectangle, thus the hollow foot formed is roughly in hollow flat column.Understandably, in some other embodiment, fixed block 10 and insert the cross section of block 20 can be curved, thus the hollow foot formed is roughly in hollow cylindric.

In certain embodiments, described hollow foot also comprises the end plug 30 in the cavity 101 that is plugged in and is enclosed to form by the inner surface 100 of fixed block 10 and the inner surface 200 that inserts block 20.Be appreciated that end plug 30 can be two, lay respectively at the two ends of cavity 101.

Simultaneously with reference to figure 3, described fixed block 10 has relative inner surface 100 and outer surface 102, and the inner side end 103 that two relative, and inner side end 103 is connected between inner surface 100 and outer surface 102.

The inner surface 100 of described fixed block 10 is recessed to form draw-in groove 12, and draw-in groove 12 is two, and be respectively used to be connected together the dependency structure inserted on block 20.The relative Liang Ge edge of the inner surface 100 of described fixed block 10 forms breach 14, and also, breach 14 is formed in two inner side end 103 places of fixed block 10.Described breach 14 inserts the corresponding construction on block 20 for being connected.The degree of depth D2 of described breach 14 is greater than the degree of depth D1 of described draw-in groove 12.

Simultaneously with reference to figure 4, described insertion block 20 also has relative inner surface 200 and outer surface 202, and the inner side end 203 that two relative, and inner side end 203 is connected between inner surface 200 and outer surface 202.The inner side end 203 of described insertion block 20 extends to form trip 22.When two insertion blocks 20 are connected with two fixed blocks 10 respectively, two described trip 22 correspondences inserted on blocks 20 are fastened in the draw-in groove 12 of two fixed blocks 10.In embodiment shown in figure, each inner side end 203 extends to form a trip 22, understandably, in different embodiment, on an inner side end 203 also extensible formation two or three wait the trip 22 of varying numbers, correspondingly, the draw-in groove 12 of also quantity of formation coupling on the inner surface 200 of fixed block 10.Described insertion block 20 extends from inner side end 203 projection 24 coordinated with the breach 14 on fixed block 10, and the outer surface of described projection 24 is concordant with the outer surface 202 inserting block 20.

Refer again to Fig. 1, after fixed block 10 and insertion block 20 combine, draw-in groove 12 engages with trip 22, projection 24 coordinates with breach 14, and breach 14 is opened in end, and the degree of depth of breach 14 is greater than the degree of depth of draw-in groove 12, the joint line of fixed block 10 and insertion block 20 can be made as far as possible near the outer surface 102 of fixed block 10, thus, in the process of following process hollow foot, such as paint waits in the process of surface treatment procedure, and hollow foot can not easily ftracture.Arranged by this kind, hollow foot not only has lighter weight, consumes timber less, and has more reliable quality, can not produce the quality problems such as cracking in following process process.

In certain embodiments, the position that the edge of the outer surface 102 of described fixed block 10 is corresponding with breach 14 forms circular arc chamfering 13, and the outer surface 102 of described fixed block 10 is by the outer surface 202 of described circular arc chamfering 13 rounding off to described insertion block 20.So, the joint line of fixed block 10 and insertion block 20 is more hidden, and the outward appearance of hollow foot is more attractive in appearance, and also inhibited to phenomenons such as the issuable cracking of subsequent treatment operation such as paint.

In certain embodiments, breach 14 degree of depth D2 of described fixed block 10 is the 73%-80% of the thickness D of described fixed block 10, and draw-in groove 12 degree of depth D1 of described fixed block 10 is the 30%-50% of the thickness D of described fixed block 10.

In one specific embodiment, as shown in Figure 3, the thickness D of described fixed block 10 is 15mm, and the degree of depth D2 of described breach 14 is 11.5mm, and the degree of depth D1 of described draw-in groove 12 is 6mm.Adapt with the degree of depth D2 of described breach 14, the width of the projection 24 of described insertion block 20 is 11.5mm.Adapt with the degree of depth D1 of described draw-in groove 12, the width of the trip 14 of described insertion block 20 is 6mm.

As shown in Figure 3, the width W 1 of described fixed block 10 is 75mm.Composition graphs 1 and Fig. 4, it is foursquare hollow cylinder that described insertion block 20 and fixed block 10 enclose formation one cross section, and the width W 2 of described insertion block 20 is 45mm.

Further, the thickness T of described insertion block 20 is 16mm, and the thickness T1 of described trip 22 is 6mm, and the thickness T2 of described projection 24 is 5mm.

Further, the inner surface of described trip 22 is concordant with the inner surface 200 inserting block 20, forms gap 23 between the trip 22 on the inner side end 203 of described insertion block 20 and projection 24.In the embodiment shown in fig. 4, the thickness T2 of the thickness in gap 23 and the thickness T1 of trip 22, projection 24 is suitable, is roughly 1/3rd of the thickness T inserting block 20.

The utility model adopts hollow foot, compared with solid pin, can save the material of 27%, reduce the consumption to timber, reduce costs.Hollow foot arranges the larger breach of the degree of depth on fixed block in addition, and breach is positioned at the edge of the inner surface of fixed block, the joint line of fixed block and insertion block can be made as far as possible near the outer surface of fixed block, avoid subsequent handling hollow core pin to ftracture, promote the quality of hollow foot.

The utility model also provides a kind of brace table, comprises any one hollow foot above-mentioned.Brace table can be the tables such as table platform, workbench, also can be the platform such as chair, stool, and hollow foot is as the feet of these tables and platform.

Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.

The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
