Abstract
A pulling-out type stair tread belongs to the field of stair treads and comprises a core plate, an inner side plate and two end plates. Tenons which are outwards protruded are formed on three sides of the core plate, grooves matching with the tenons are arranged on the inner side plate and the end plates, rabbets extending outwards are disposed at two ends of the inner side plate, one end of each end plate is provided with a mortise matching with the corresponding rabbet, the rabbets at the two ends of the inner side plate are respectively in joggle joint with the mortises on the two end plates, so that a 'C'-shaped frame is formed, the core plate is clamped in the frame, and a circular lock block is further disposed at the other end of each end plate. The pulling-out type stair tread has the advantages of simple structure and convenience in detachment and replacement.
Description
Technical field
The utility model relates to the broadstep field, especially relates to a kind of pull-out type broadstep.
Background technology
At present, often cover one deck broadstep on stair or the step, can revise stairway step or increase attractive in appearance.Broadstep mostly uses firm wear-resisting and have a pleasing precious wood of outward appearance; But in use, broadstep wearing and tearing still can occur or damage, or because of weather former thereby cracking; Change broadstep like this and just bother very much, therefore a kind of appearance of removable broadstep is necessary.
Summary of the invention
In order to overcome existing shortcoming, the purpose of the utility model provides a kind of simple in structure, is convenient to a kind of pull-out type broadstep of dismounting and change.
The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of pull-out type broadstep; Comprise central layer, interior side plate and two end plates, three limits of said central layer all are formed with outwards outstanding tenon, in said, all offer the groove that is complementary with said tenon on side plate and the said end plate; The two ends of side plate also are provided with outward extending tenon in said; One end of said end plate is provided with the mortise that is complementary with said tenon, said on the side plate two ends said tenon respectively with two said end plates on said mortise joggle mutually, to form " C " type framework; Said central layer is placed in the said framework, also is provided with a circular lock dog at the other end of said end plate.
Be provided with a breach at said lock dog, said breach is identical with said groove.Being 90 degree joggles between side plate and the said end plate in said, is 45 degree joggles between said interior side plate and the said end plate.
The beneficial effect of the utility model is simple in structure, is convenient to dismounting and change.
Description of drawings
Fig. 1 is the utility model: the overall structure sketch map of a kind of pull-out type broadstep embodiment 1;
Fig. 2 is the utility model: the overall structure sketch map of a kind of pull-out type broadstep embodiment 2.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Embodiment 1, and with reference to shown in Figure 1, it is the technical scheme of 90 degree joggles that present embodiment has proposed between interior side plate 2 and the end plate 3.Comprise central layer 1, interior side plate 2 and two end plates 3 in the present embodiment; Three limits of said central layer 1 all are formed with outwards outstanding tenon 4; In said, all offer the groove 5 that is complementary with said tenon 4 on side plate 2 and the said end plate 3, the two ends of said interior side plate 2 also are provided with outward extending tenon 8, and an end of said end plate 3 is provided with the mortise 9 that is complementary with said tenon 8; Said tenon 8 in said on side plate 2 two ends respectively with two said end plates 3 on said mortise 9 joggle mutually; To form " C " type framework, said central layer 1 is placed in the said framework, also is provided with a circular lock dog 6 at the other end of said end plate 3; Be provided with a breach 7 at said lock dog 6, said breach 7 is identical with said groove 5.
When the tenon 4 of central layer 1 places in the groove 5 fully, rotation lock dog 6, central layer just can not skid off in groove 5 like this; When needing to change central layer 1, rotation lock dog 6 makes breach 7 parallel with groove 5, and central layer 1 just can be pulled out in groove 5 easily.
Embodiment 2, and is as shown in Figure 2, and it is the technical scheme of 45 degree joggles that present embodiment has proposed between interior side plate 2 and the end plate 3.Comprise central layer 1, interior side plate 2 and two end plates 3 in the present embodiment; Three limits of said central layer 1 all are formed with outwards outstanding tenon 4; In said, all offer the groove 5 that is complementary with said tenon 4 on side plate 2 and the said end plate 3, the two ends of said interior side plate 2 also are provided with outward extending tenon 8, and an end of said end plate 3 is provided with the mortise 9 that is complementary with said tenon 8; Said tenon 8 in said on side plate 2 two ends respectively with two said end plates 3 on said mortise 9 joggle mutually; To form " C " type framework, said central layer 1 is placed in the said framework, also is provided with a circular lock dog 6 at the other end of said end plate 3; Be provided with a breach 7 at said lock dog 6, said breach 7 is identical with said groove 5.
When the tenon 4 of central layer 1 places in the groove 5 fully, rotation lock dog 6, central layer just can not skid off in groove 5 like this; When needing to change central layer 1, rotation lock dog 6 makes breach 7 parallel with groove 5, and central layer 1 just can be pulled out in groove 5 easily.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
