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 to 6, a building construction ladder, includes two ladder poles 1 and connects a plurality of climbing poles 2 of two ladder poles 1, and ladder pole 1 lower extreme still is equipped with and accomodates groove 10 and put through and accomodate groove 10 and external first sliding tray 11, and this building construction ladder still includes:

the swing rod 3 is hinged on the ladder rod 1 and can swing into the accommodating groove 10, and a second sliding groove 30 is formed in the swing rod 3 along the length direction of the swing rod 3;

the two ends of the diagonal brace 4 are connected with the locking assemblies 40, and the two locking assemblies 40 can penetrate through the first sliding groove 11 and the second sliding groove 30 respectively.

It is concrete, pull out rocking rod 3 from accomodating the inslot 10 during the use at first, then support the upper and lower both ends of terraced pole 1 respectively on the high wall and subaerial, later let rocking rod 3 support subaerial at terraced pole 1 below again, thereby let terraced pole 1 lower extreme, rocking rod 3 and ground form the isosceles triangle structure, then move suitable position back along first sliding tray 11 and second sliding tray 30 respectively with 4 both ends of diagonal brace, the locking Assembly 40 of screwing again, with the relative position between rocking rod 3 and the terraced pole 1 through 4 locking diagonal braces, thereby strengthen the bearing structure of terraced pole 1 bottom, not only can prevent the slide of terraced pole 1 lower extreme, and make the bearing structure of this construction ladder nearer from its focus, stability is better. On the other hand, when the ladder is used in an area with uneven terrain or an area where the swing lever 3 cannot be opened, the swing lever 3 can be accommodated in the accommodating groove 10 without affecting the use of the ladder as a general ladder. On the other hand, in order to facilitate the storage of the swing rod 3 and prevent the swing rod 3 from shaking randomly when being stored in the storage groove 10 again, in the embodiment, magnetic members can be arranged in the swing rod 3 and the storage groove 10, so that the two magnetic members attract each other to provide locking force for the storage of the swing rod 3.

Further, in order to allow the sway bar 4 to remain attached to the sway bar 3 and the ladder bar 1 without being detached after the sway bar 3 is placed in the accommodating groove 10, in this embodiment, the ladder bar 1 is further provided with a positioning through groove 12 communicating with the accommodating groove 10, and a locking member 40 disposed through the second sliding groove 30 can be disposed in the positioning through groove 12. When the swing rod 3 needs to be stored, firstly, the two locking assemblies 40 are loosened, then the group of locking assemblies 40 connected with the swing rod 3 is moved to the uppermost position of the second sliding groove 30, then the swing rod 3 is swung and placed into the storage groove 10, and meanwhile, the group of locking assemblies 40 just enter the positioning channel 12, so that the storage work of the swing rod 3 cannot be hindered.

Furthermore, the ladder bar 1 is also provided with a first fastening groove 13 extending along the first sliding groove 11 in the accommodating groove 10, and a second fastening groove 31 extending along the second sliding groove 30 is also arranged on one side of the swinging rod 3;

the locking assemblies 40 comprise rotating members 401 and nuts 402, one end of the rotating member 401 penetrates through the diagonal brace 4, the rotating members 401 of the two locking assemblies 40 are further respectively arranged through the first sliding groove 11 and the second sliding groove 30, and the nuts 402 of the two locking assemblies 40 are respectively arranged in the first fastening groove 13 and the second fastening groove 31 and are respectively in threaded connection with the two rotating members 401.

Specifically, in the set of locking assemblies 40 connected to the ladder bar 1, the nut 402 is located in the first fastening groove 13, and the rotating member 401 is inserted into the first fastening groove 13 and is not inserted into the accommodating groove 10, so that when the swing rod 3 is placed into the accommodating groove 10, the rod body portion of the swing rod 3 does not touch the set of locking assemblies 40; in another set of the locking assembly 40 connected to the swing lever 3, the nut 402 is located in the second fastening groove 31, and the rotating member 401 does not penetrate the second fastening groove 31, so that when the swing lever 3 is placed in the accommodating groove 10, neither the rotating member 401 nor the nut 402 touches the wall surface of the accommodating groove 10. Therefore, the above structure can prevent the swing lever 3 from being caught outside the housing groove 10 and not entering.

Further, in order to balance the stress of the ladder bars 1 on the two sides, in this embodiment, the building construction ladder further includes a connecting rod 5, two swinging rods 3 and two inclined supporting rods 4 are respectively connected to the two ladder bars 1, and two ends of the connecting rod 5 are respectively connected to the two swinging rods 3. The arrangement of the connecting rod 5 enables the two oscillating rods 3 to move simultaneously to accelerate the adjustment of the support structures on both sides.

Further, in order to prevent the existence of the connecting rod 5 from obstructing the storage operation of the swing rod 3, in this embodiment, the rear side of the climbing rod 2 is further provided with a storage groove 20 communicating with the storage grooves 10 on both sides, the connecting rod 5 can be placed in the storage groove 20, and on the other hand, the arrangement is also beneficial to thickening the connecting rod 5.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of exemplary embodiments according to the application. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
