Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. 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.

As shown in fig. 1 to 5, the utility model provides a special staircase instrument, this staircase instrument is applicable to the single face wall body that needs frequently to change clean position, specifically including imbedding pulley yoke 1 in the wall body and setting up subaerial staircase 5, pulley yoke 1 includes hollow inner chamber, pulley yoke 1's inside is equipped with two and can follows the gliding assembly pulley 2 of pulley yoke 1 inner chamber, and two assembly pulley 2 are connected with handrail frame 3 respectively through the bolt, handrail frame 3 is "V" type, and handrail frame 3 keeps away from the one end of pulley yoke 1 and is connected with staircase 5.

The handrail frame 3 is driven to move along the pulley frame by sliding the two groups of pulley blocks 2 in the pulley frame 1; when the handrail frame 3 is pulled, because the two groups of pulley blocks 2 are clamped in the pulley frame 1, one end of the handrail frame 3 is difficult to separate from the pulley frame 1, thereby enhancing the connection strength of the handrail frame 3.

The lower extreme of staircase 5 is equipped with two sets of universal wheels 6 that can the free rotation, and the user pushes away the wall body through the side on staircase 1 clear in-process for the device removes about pulley yoke 1 under the effect of two sets of assembly pulley 2 and two sets of universal wheels 6, need not the user and makes a round trip to scramble the position of adjusting staircase 1, realizes the cleaning work to whole wall, improves the convenience of use, improves work efficiency, alleviates work burden.

The one end that pulley yoke 1 was kept away from to handrail frame 3 is connected with staircase 5, and the lateral surface branch of two handrail frames 3 all is equipped with connecting bolt 4, and the upper end of staircase 5 is equipped with the spout 501 that sets up along length direction, and connecting bolt 4 runs through to be installed in spout 501, and connecting bolt 4 can be driven and slide along spout 501. The connecting bolt 4 is in threaded connection with the armrest frame 3 through a threaded hole, and the outer end of the connecting bolt 4 is provided with an operating handle.

When 5 inclination great lead to the user of staircase far away from the wall, need adjust 5 gradients of staircase, the user sits at the wall of 3 departments of handrail frame, loosen two sets of connecting bolt 4 through twisting the operating handle, and tighten up staircase 5 to the wall is interior, make the gradient of staircase 5 adjusted, it makes the angle of staircase 5 fixed to screw up two sets of connecting bolt 4 this moment, convenient to use person is clean the wall of different distances on staircase 5, the accommodation of staircase has been promoted, the practicality of staircase has been increased.

When staircase 5 is the biggest inclination, connecting bolt 4 is located the top in draw-in groove 501 this moment, along with staircase 5 is constantly to the internal contraction, can drive connecting bolt 4 and be located the relative position decline of draw-in groove 501, when staircase 5 was close perpendicular ground's state, connecting bolt 4 was located draw-in groove 501 below the bottom this moment, has strengthened staircase 5's factor of safety.

As shown in fig. 1 and 3, the one end that is close to pulley yoke 1 between two sets of handrail frame 3 is equipped with connects dull and stereotyped 301, and two sets of handrail frame 3 are through connecting dull and stereotyped 301 fixed connection, connect dull and stereotyped 301 with two sets of handrail frame 3 fixed connection, the steadiness that handrail frame 3 is connected has been promoted, and through welded support flat board 302 fixed connection between the both ends of handrail frame 3, make handrail frame 3 by supporting dull and stereotyped 302 and ground contact when being pulled, consequently handrail frame 3 can not incline, the probability that handrail frame 3 damaged has been reduced.

As shown in fig. 1, one end of the handrail frame 3, which is located on the connecting bolt 4, is provided with a limiting clamping groove 8, the side surface of the top end of the handrail frame 5 is provided with a limiting clamping block 502 matched with the limiting clamping groove 8, when the handrail frame 5 is installed on the outer side of the handrail frame 3, the handrail frame 5 is matched with the limiting clamping groove 8 through the limiting clamping block 502, so that the rotation angle of the handrail frame 5 is limited at the position perpendicular to the ground or at the position parallel to the joint of the handrail frame 3, the user is not easy to generate excessive inclination in the process of adjusting the angle of the handrail frame 5, the handrail frame is matched with the limiting sliding groove 501 and.

As shown in fig. 1, pulley yoke 1 is provided with two sets of adjustable pulley stopper 7, pulley block stopper 7 is including running through and block the spacing bolt 701 of pulley block stopper 7, and there is a spacing slider 702 at the bottom of spacing bolt 701 through threaded connection, spacing slider 702 activity block is in pulley yoke 1's inside, can contact with pulley stopper 7 when assembly pulley 2 slides to spacing region, make staircase 5 can't continue to slide, through loosening the position that adjustable pulley block stopper 7 of spacing bolt 701 is located on pulley yoke 1, because pulley block stopper 7 and the spacing slider 702 extrusion pulley yoke 1 that area of contact is great after spacing bolt 701 screws up, consequently be difficult for causing the damage to pulley yoke 1.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
