Abstract
The utility model provides a ladder fixing device for the ladder is the fixing device the during operation on being similar to the cylinder, has solved present people safety problem and the extravagant problem of manpower during with the ladder on the cylinder, by U -shaped card, hinge, dead lever, rotation axis, and torsion spring, the pin, the constitution is violently stepped on to aperture, ladder. The opening of U -shaped card outwards opens certain angle, and the center that hinge and ladder foot bar were crossed to the U -shaped cartoon combines, and the hinge can be 90 degrees within ranges upsets, and the extreme point position of U -shaped card both ends pole has an aperture respectively, and above the fixed axle lay in the U -shaped card, the extreme point position that rotation axis and U -shaped card are passed through to the one end of fixed axle linked to each other, and it is rotatory to make the fixed axle wind the rotation axis, and the other end passes through torsion spring and the U -shaped card is fixed links to each other to the fixed axle extreme point has an aperture. This design cost is low, simple and practical, easy production and popularization.
Description
Technical field
The utility model relates to a kind of ladder securement device, especially a kind ofly ladder can be fixed on the device be similar on the object of cylinder.
Background technology
At present, when ladder uses on the object being similar to cylinder, stability is strong, needs people to help to hold up or with rope binding, and the former waste of manpower the latter safety is not high yet.
Summary of the invention
The design be in order to solve ladder be similar to cylindrical object uses time instability problem, and a kind of ladder securement device provided.
Technical scheme:
The utility model is by U-shaped card, and hinge, fixed bar, axis of rotation, torsionspring, pin, aperture, ladder is horizontal steps on formation.The outward opening opened with certain angle of U-shaped card, U-shaped cartoon is crossed hinge and is combined with the center of ladder treadle, hinge can overturn within the scope of 90 degree, the endpoint location of U-shaped card two ends bar has an aperture respectively, fixed axis is positioned at above U-shaped card, and one end of fixed axis is connected by the endpoint location of axis of rotation with U-shaped card, and fixed axis can be made to rotate around axis of rotation, the other end to be fastened with U-shaped by torsionspring and is connected, and fixed axis end points has an aperture.
Beneficial effect:
The design's structure is simple, can effectively prevent ladder from sliding, to improve the safety and stability of ladder.Hold up ladder when ladder operation without the need for people, thus improve the safety of ladder and effectively saved manpower.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and enforcement, the utility model is further illustrated.
(in each figure, same section label is consistent)
Fig. 1 is a kind of structural representation of ladder securement device.
Fig. 2 is the structural representation of a kind of ladder securement device operation on the cylinder.
Fig. 3 is the structural representation taking out a kind of ladder securement device.
In figure: 1.U shape is blocked, and 2. hinge, 3. fixed bar, 4. axis of rotation, 5. torsionspring, 6. pin, 7. aperture, 8. ladder is horizontal steps on, 9. cylinder.
Detailed description of the invention
As shown in Figure 1, the utility model is by U-shaped card 1, and hinge 2, fixed bar 3, axis of rotation 4, torsionspring 5, pin 6, aperture 7, ladder is horizontal steps on 8 formations.
The utility model is by U-shaped card 1, and hinge 2, fixed bar 3, axis of rotation 4, torsionspring 5, pin 6, aperture 7, ladder is horizontal steps on 8 formations.The outward opening opened with certain angle of U-shaped card 1, the center that U-shaped card 1 steps on 8 by hinge 2 and ladder is combined, hinge 2 can overturn within the scope of 90 degree, during use, U-shaped card 1 plane is parallel to the ground, the endpoint location of U-shaped card 1 two ends bar has an aperture 7 respectively, fixed bar 3 is positioned at above U-shaped card 1, one end of fixed bar 3 is connected with the endpoint location of U-shaped card 1 by axis of rotation 4, fixed bar 3 can be made to rotate around axis of rotation 4, the other end is fixedly linked by torsionspring 5 and U-shaped card 1, and fixed bar 3 end points has an aperture 7.
As shown in Figure 2, ladder when idle and U-shaped card 1 stick in two aperture 7 pins 6 of fixed bar 3, fixed bar 3 is connected with U-shaped card 1 torsionspring 5.When we during operation, first take off pin 6 with ladder on the object being similar to cylinder 9 from U-shaped Ka1Chu, then adjust U-shaped card 1, make itself and ladder at an angle.In the process that ladder is put on cylinder 9, cylinder 9 and fixed bar 3 extrude, torsionspring 5 shrinks to the inside, fixed bar 3 is driven also inwardly to shrink, until after cylinder 9 enters U-shaped card 1, fixed bar 3 and cylinder 9 without extruding, thus make torsionspring 5 drive fixed bar 3 outwards to stretch, thus fixed ladder, fixed effect is as shown in Figure 3.
Claims (1)
