In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected" and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The specific embodiment is as follows:

example 1, as shown in figures 1-4, a ladder stand for construction purposes comprises two uprights 1 and a number of foot members. Two erects to prop 1 parallels and the clearance setting, and a plurality of pedal spare vertical connection are between two erects to prop 1, and the person of facilitating the use scrambles.

The footrest member comprises two cross-braces 2 and a hinge assembly 3. Specifically, two crossbearers 2 are symmetrically arranged, and the two crossbearers 2 are respectively connected with two vertical braces 1 in a rotating manner. The vertical braces 1 are provided with the stop blocks 11, when the cross braces 2 rotate to be perpendicular to the vertical braces 1 and between the two vertical braces 1, the cross braces 2 are lapped on the stop blocks 11, so that the stop blocks 11 support and stop the cross braces 2, and the cross braces 2 are prevented from continuously rotating downwards.

The hinge assembly 3 comprises two U-shaped plates 31, a coupling lug 33 and a locking mechanism. Specifically, two engaging lugs 33 are arranged at the end of each U-shaped plate 31, and the two engaging lugs 33 respectively overhang from two side walls of the U-shaped plate 31, so that the two engaging lugs 33 are parallel and have a gap. The two U-shaped plates 31 are respectively connected to the lower side surfaces of the two cross braces 2, the openings of the U-shaped plates 31 face downwards, the connecting lugs 33 on the two U-shaped plates 31 are partially overlapped and staggered, and the four connecting lugs 33 penetrate through the second rotating shaft 32 to realize the hinging of the two U-shaped plates 31; therefore, the two cross braces 2 are connected in a rotating mode, the two cross braces 2 synchronously rotate downwards towards the space between the two vertical braces 1, and the two cross braces 2 are perpendicular to the two vertical braces 1 under the support of the stop block 11, so that the ladder stand is unfolded to be climbed by a user; and when not using, tighten up two crossbearers 2 synchronous upwards rotatory together, two crossbearers 2 are rotatory 1 vertical braces relatively for two vertical braces 1 tighten up together, have reduced the occupation space of this cat ladder like this, convenient storage.

In this embodiment, as shown in fig. 2, the left and right width of the connecting lug 33 is smaller than the left and right width of the U-shaped plate 31, so that the two U-shaped plates 31 can be more tightly folded together when being folded.

This embodiment is a cat ladder for building when using, struts the pedal piece between two erects props 1 downwards, and two studding 2 of every pedal piece are rotatory downwards and make and keep perpendicular with two erects props 1 to support this cat ladder in certain holding surface, the person of being convenient for uses scrambles. When not using, upwards rotate and tighten up together two stull 2 of every pedal piece, the relative erector strut 1 of the 2 other ends of stull is rotatory to make two erector struts 1 tighten up together, in order to reduce the area occupied of this cat ladder, convenient storage.

Further, the second rotating shaft 32 is riveted to achieve the movable riveting of the two U-shaped plates 31 of each hinge assembly 3. The riveting has the advantages of simple process equipment, shock resistance, impact resistance, firmness, reliability and the like.

Furthermore, the U-shaped plates 31 are connected with the corresponding cross braces 2 in a welding mode, so that the connection performance is good, the rigidity of a welding structure is high, and the integrity is good.

Further, the locking mechanism includes a telescopic column 311 and a limit groove. Specifically, a telescopic hole is formed in the inner side of one side wall of one of the U-shaped plates 31, the telescopic column 311 extends into the telescopic hole, and an elastic member is arranged in the telescopic hole and connected with the telescopic column 311, so that the telescopic column 311 is stretched. Be provided with the spacing groove in the lateral wall outside of another U template 31, when two U templates 31 receipts were closed together, flexible post 311 corresponds with the spacing groove position for flexible post 311 tip stretches into the spacing inslot, realizes locking when articulated subassembly 3 receipts are closed, appears rocking at will when effectively avoiding this cat ladder to pack up, and stability is high.

Further, the end of the telescopic column 311 extending out of the telescopic hole is a spherical surface, and the limit groove is an arc groove body matched with the spherical surface of the telescopic column 311, so that the telescopic column 311 is smoother when passing in and out of the limit groove.

Further, the connecting block 21 is arranged on the upper side face of the end portion, close to the left vertical support 1, of the left cross support 2, the connecting block 21 stretches upwards in an overhanging mode, the connecting block 21 penetrates through the first rotating shaft 22 to achieve rotating connection of the connecting block 21 and the vertical support 1, and then rotating connection between the cross support 2 and the vertical support 1 is achieved. In this way, the arrangement of the connecting block 21 makes the two vertical supports 1 close to each other when the ladder is folded, and the occupied space is reduced.

In the embodiment, the first rotating shaft 22 is a rivet, so that the connecting block 21 and the vertical support 1 are movably riveted.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without the technical solutions of the present invention, or the present invention can be directly applied to other occasions without the improvements, and all are within the protection scope of the present invention.
