Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a herringbone ladder fixed stainless steel angle-adjustable hinge comprises a left hinge 1 and a right hinge 2, wherein the left hinge 1 and the right hinge 2 are both of an L-shaped structure, the upper right corner of the left hinge 1 is hinged with the upper left corner of the right hinge 2 through a connecting piece 3, the left hinge 1 and the right hinge 2 rotate relatively by taking the connecting piece 3 as an axis, a plurality of fixed connecting holes 4 are respectively formed in the left hinge 1 and the right hinge 2, an outer edge 5 is arranged on the left side edge of the left hinge 1 and the right side edge of the right hinge 2 to be tightly connected with a fixed object so as to improve safety, inner edges 6 are arranged on the lower right part of the left hinge 1 and the lower left part of the right hinge 2 to be more attached to the wrapped object and be connected seamlessly so as to improve safety, a fixing bolt 7 is fixedly arranged on the lower end of the right side protrusion of the left hinge 1, a waist-shaped hole 8 is formed in the lower end of, the rotation angle of right hinge 2 is by waist shape hole 8 length restriction, through fixing bolt 7 and waist shape hole 8's combined use, and the double ladder that makes when fixing bolt 7 activity to waist shape hole 8's top, the angle reaches the biggest, can not unrestricted increase, has guaranteed double ladder's normal use promptly, can not bring the potential safety hazard because of the span of opening is too big again to great promotion holistic practicality.
Furthermore, at least five fixed connecting holes 4 are formed in each hinge of the left hinge 1 and the right hinge 2 and are concave with inward openings, and at least five fixed connecting holes 4 are formed, so that the connection between the hinges and the herringbone ladder is firmer, and the overall stability is improved.
Furthermore, the outer wrapping edge 5 and the inner wrapping edge 6 are perpendicular to the plane of the hinge at an angle of 90 degrees, and the connection between the hinge and the herringbone ladder can be further reinforced through the attachment of the wrapping edges and the herringbone ladder, so that the stability is improved.
Furthermore, the hinge is fixedly connected with the herringbone ladder body through the self-tapping screws arranged in the fixed connecting holes 4, and the self-tapping screws and the herringbone ladder body are connected, so that the self-tapping screws and the herringbone ladder body can be combined more firmly, and the overall safety is improved.
Further, the interval of outsourcing limit 5 and endocyst limit 6 is the same with double ladder stand width, and interval between them is the same, can make outsourcing 5 and endocyst limit 6 more laminate with the double ladder main part, can not destroy easily.
The working principle is as follows: the double ladder is fixed with stainless steel hinges, firstly, the hinges are connected with the top of the double ladder through the inner and outer wrapping edges on the left and right hinges and the fixed connecting holes 4 by screws, then the herringbone ladder is opened, so that the fixing bolt 7 moves to the top of the waist-shaped hole 8, a person goes up to carry out operation work, and in the using process of the herringbone ladder, through the combined use of the fixing bolt and the waist-shaped hole, when the fixing bolt moves to the top end of the waist-shaped hole, the angle reaches the maximum and can not be increased without limit, not only ensures the normal use of the herringbone ladder, but also can not bring potential safety hazard due to overlarge opening span, by combining the combination of the inner and outer wrapping edges and the plurality of fixed connecting holes 4, the hinge is more attached to the top end of the herringbone ladder, can be more effectively fixed on a product, plays a role in safety and firmness, and through the design, thereby expanding the whole application range on the basis of effectively improving the whole comprehensive use performance.
