Specific embodiment
Make further with substantive distinguishing features of the specific embodiment to the utility model with reference to the accompanying drawings of the specification
It is bright.
A kind of step assembling structure delimited with buckle-type side as shown in Figs 1-4, by symmetrically arranged tripod 1, across
It connects the crossbeam 2 between 1 top of tripod, the pedal 3 being mounted on above 2 middle part of crossbeam and is mounted on 2 liang of upper sides of crossbeam
4 compositions are delimited in side, and 2 both ends of crossbeam offer vertically communicated button hole 5, and the side is delimited 4 bottom surfaces and is downwardly extending
Fastener 6(is as shown in Figure 2), the side delimits 4 and is mounted on 3 liang of pedal from top to bottom by that can match the fastener 6 of snapping with button hole 5
Side is connected so that the side is delimited 4 top surfaces and flushed with 3 top surface of pedal.
During installation, first transverse part is inserted into diagonally forward in limit slot, so that after positioning column 12 and fastener 6 avoid crossbeam 2
Edge is simultaneously respectively moved to 5 top of corresponding location hole 13 and button hole, and later, side delimits 4, and to limit, slot and transverse part are up-front to be supported
Touching is swung centered on region, so that positioning column 12 and fastener 6 are planted respectively is connected to corresponding location hole 13 and button hole 5
It is interior, realize that 4 installations are delimited in side.
After completing assembly, positioning column 12 is vertically plugged in location hole 13, is delimited 4 to crossbeam 2 and side and is played horizontal direction
The effect of positioning；Fastener 6 is vertically buckled in button hole 5, is delimited 4 to crossbeam 2 and side and is played the role of vertically positioning；Transverse part leading edge
Holding effectively prevent side to delimit 4 and deviates backward in limit slot.At this point, the bottom surface that side delimits 4 is overlapped on the top of supporting table 7
On face, the top surface that side delimits 4 is flushed with 3 top surface of pedal, and the side wall that side delimits 4 is bonded with the matching of the side wall of pedal 3, is effectively reduced
Gap between the two, it is ensured that aesthetics and safety.
In actual operation, protuberance forms the supporting table 7(such as Fig. 3 institute being arranged along its length in the middle part of the crossbeam 2
Show), contradicted with 3 bottom surface of pedal in the middle part of the top surface of the supporting table 7, top surface both ends open up the button hole 5, the fastener 6 and its
The button hole 5 of lower section corresponds to one by one.The section of the supporting table 7 is square, and can delimit 4 for pedal 3 and side and provide gentle support,
The anti-deformation nature of crossbeam 2 can also be effectively improved.Crossbeam 2 both plays the role of that pedal 3 and side is supported to delimit 4, moreover it is possible to ensure two
1 relative position of tripod is fixed, so that step has preferable anti-deformation nature, improves safety in utilization, it is ensured that service life.
In actual operation, the fastener 6 includes two elastic rods 8 disposed in parallel, and two 8 bottom ends of elastic rod are backwards
Side is equipped with button block, and the top surface of the button block is overlap joint plane, and the bottom surface of the button block is oblique to be arranged towards 5 edge of button hole
Face.Matching backwards to side wall distance between the surface with the width of the button hole 5 for the elastic rod 8, is equipped between deformation between the elastic rod 8
Gap, 8 deformation of elastic rod is drawn close so that button block passes through the button hole 5 from top to bottom.Deformation clearance gap between elastic rod 8
From the thickness for being greater than the button block, deformation gap can provide sufficient deformation space for elastic rod 8, enable button block in elastic rod
5 edge of button hole is effectively avoided after 8 deformation, it is ensured that button block resets deformation using elastic rod 8 after smoothly passing through button hole 5 and holding exists
On the front port periphery of button hole 5.The elastic rod 8 is arranged in each other on the wall surface of side in the button block, it is ensured that button block can be
Limit (as shown in Figure 4) is fastened with crossbeam 2 after the reply deformation of elastic rod 8.It is moulding made of integral type that the side, which is delimited, really
Protecting elastic rod has preferable structural strength and elastic-restoring force.
In actual operation, the fastener 6 at least two, and equidistantly split on the bottom surface that the side delimits 4.It is preferred that
Scheme, the fastener 6 are three, and 5 quantity of button hole is corresponding with 2 quantity of crossbeam, and the top surface span of the tripod 1 is connected to three
A crossbeam 2, the both ends of each crossbeam 2 open up button hole 5 respectively, and 2 installation site of crossbeam and 6 position of fastener are corresponding one by one, it is ensured that
When 4 installation is delimited in side, each fastener 6 is synchronous to be inserted into corresponding button hole 5, effectively improves assembly efficiency, and facilitate later period demolition and maintenance.
In actual operation, the crossbeam 2 includes a preposition beam for being connected across 1 top surface front of tripod, the tripod 1
Front side wall be equipped with a front apron 9, the front apron 9 include be bonded with preposition soffit be arranged transverse part and with tripod 1
The affixed vertical part of front side wall.The side delimits 4 front end bottom surfaces and is downwardly extending a barb 10, and 10 bottom of barb has court
The coupler body 11 extended to form afterwards is enclosed between 11 top surface of coupler body and side 4 bottom surfaces of demarcation and inserts for the transverse part leading edge level
The limit slot set.Barb 10 had both played the role of constrained side demarcation 4 and had deviated backward, and also acting as, which prevents side from delimiting 4, is vertically detached from
The effect of 2 step of crossbeam.
Preferably, the notch of the limit slot is horizontally disposed, the side delimited between 4 bottom surfaces and transverse part top surface, coupler body
Fit-up gap is equipped between 11 top surfaces and transverse part bottom surface.It is arranged after limiting the notch horizontal direction of slot, is inserted into convenient for transverse part leading edge.
The size of fit-up gap should be set according to 6 length of fastener and 12 length of positioning column, met evacuation and required.
In actual operation, the side delimits 4 bottom surfaces and is downwardly extending positioning column 12, opens on the end of the crossbeam 2
If opening up the avoid holes being arranged with the matching of corresponding positioning column 12 on the transverse part for the location hole 13 that positioning column 12 is vertically planted,
The positioning column 12 passes through location hole 13 from top to bottom and is plugged in the avoid holes.Positioning column 12 is right one by one with location hole 13
It answers, the quantity of the location hole 13, which can according to need, to be adjusted, and at least two, preferred embodiment, 13 quantity of location hole is
Two, and split on different crossbeams 2, it prevents side from delimiting 4 and is occurring to rotate horizontally offset.In addition, the location hole 13
Quantity can also be adjusted to three, four etc., be regarded as specific embodiment of the utility model.
