Abstract
The utility model discloses a movable shelf ladder with stable contact. The shelf ladder comprises a vertical post I, a vertical post II, and horizontal supporting plates which are connected between the vertical post I and the vertical post II, wherein the upper end and the lower end of the vertical post I are respectively connected with a hinge pin I, rotating wheels I are mounted on the hinge pins I, supporting posts I are connected to the outer edges of the rotating wheels I, the upper end and the lower end of the vertical post II are respectively connected with a hinge pin II, rotating wheels II are mounted on the hinge pins II, supporting posts II are connected to the outer edges of the rotating wheels II, and the rotating wheels I and the rotating wheels II are opposite and unidirectional in rotation directions. The shelf ladder disclosed by the utility model not only can enlarge the contact areas with ground and with a wall, but also can be applicable to the situation with uneven ground or uneven wall, as well as is safe and reliable in use and easy in implementation.
Description
Technical field
The utility model relates to a kind of ladder, specifically belongs to a kind of mobile ladder.
Background technology
Movable ladder is used widely in the place that all kinds of needs such as daily life, indoor and outdoor building operations, ground observation are climbed temporarily due to easy to use.Yet due to movable ladder, the feet distance is less, and is little with the Area of bearing of ground, metope, dangerous accidents such as easily turning on one's side, slip when the user of service climbs.Simultaneously common ladder shape is fixed, on ground or the place of metope injustice can't normally set up.
Often need the support staff to assist to hold the ladder when at present, using mobile ladder.So not only efficient is low, and as the user of service when uneven situation occurs in the work high above the ground ladder, the support staff is difficult in time remedy.
For addressing the above problem, increase feet and contact area of ground, invented chevron shaped ladder.But in the local and construction point higher place of needs by the wall construction, double ladder is too large due to floor space, and use is restricted.
On ground, the place of metope injustice, common mobile ladder can't be set up safely, can only set up scaffold, workload is large.
The utility model content
The Area of bearing that the purpose of this utility model is to overcome present mobile ladder is little, and unsteady deficiency provides that a kind of contact supporting surface with ground, metope large and firm, the mobile ladder that the contact that applicability is strong is firm.
Realize the technical measures of above-mentioned purpose:
A kind ofly contact firm mobile ladder, formed by vertical bar one, vertical bar two, the cross binding plate that is connected between vertical bar one and vertical bar two, it is: upper end and lower end at vertical bar one are connected with respectively bearing pin one, runner one is housed on bearing pin one, is connected with support bar one on the outer of runner one; Upper end and lower end at vertical bar two are connected with respectively bearing pin two, and runner two is housed on bearing pin two, are connected with support bar two on the outer of runner two; Runner one is with runner two direction of rotation and be unidirectional.
Characteristics of the present utility model are: mobile ladder can increase and the contact area of ground, metope, can also be adapted to the situation of ground, metope injustice, and is safe and reliable, easily enforcement.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-vertical bar one, 2-vertical bar two, 3-cross binding plate, 4-bearing pin, one, 5-runner, one, 6-support bar, one, 7-bearing pin, two, 8-runner, two, 9-support bar two.
The specific embodiment
Be described further below in conjunction with accompanying drawing:
A kind ofly contact firm mobile ladder, formed by vertical bar 1, vertical bar 22, the cross binding plate 3 that is connected between vertical bar 1 and vertical bar 22.Its upper end and lower end at vertical bar 1 connects bearing pin 1 by the hole respectively, and runner 1 is installed on bearing pin 1, and welds support bar 1 on the outer of runner 1; Upper end and lower end at vertical bar 22 connect bearing pin 27 by the hole respectively, and runner 28 is installed on bearing pin 27, welding support bar 29 on the outer of runner 28; Runner 1 is opposite with runner 28 rotation directions and can only single direction rotation.
Use principle
Rotate respectively each support bar 1 and support bar 29, can make easily the contact position of its adjustment and ground, metope, increase support distances; When ground was uneven, support bar 1 that can be by adjusting respectively the lower end or the outside support angle of support bar 29 were so that mobile ladder balance.In use, due to the direction of rotation of runner 1 with runner 28, there is each other braking, from ladder and the upper personnel's of ladder weight, can not produce mobile therefore can keep fixed angle or rock in addition.
Equally, when wall surface not at ordinary times, can be respectively support bar 1 by adjusting the upper end or the outside support angle of support bar 29 so that mobile ladder balance.
Claims (1)
1. one kind contacts firm mobile ladder, formed by vertical bar one, vertical bar two, the cross binding plate that is connected between vertical bar one and vertical bar two, it is characterized in that: upper end and lower end at vertical bar one are connected with respectively bearing pin one, runner one is housed on bearing pin one, is connected with support bar one on the outer of runner one; Upper end and lower end at vertical bar two are connected with respectively bearing pin two, and runner two is housed on bearing pin two, are connected with support bar two on the outer of runner two; Runner one is with runner two direction of rotation and be unidirectional.
