Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1-2, the utility model discloses a detachable fixed knot constructs between ladder and grid for install ladder 2 on grid 1 fixedly, and will when not using ladder 2 with grid 1 separation, the ladder has the supporting leg, install vertical fixed hook 3 of arranging on the connecting beam 4 of supporting leg, fixed hook includes that the bottom is provided with montant 31, the suit of coupler body 32 and is in pressure spring 33 on the montant, the montant dress is in connecting beam's hole, the bottom of pressure spring with connecting beam's last surface contact and the top is pushed down by the bottom of installing the operating handle 35 at the montant top.

The operating handle 35 may be a quincuncial handle or other available shapes or structures.

The hook portion 32 may be formed by welding or fixing an L-shaped plate on the bottom plane of the vertical rod, and the free end of the L-shaped plate is bent upward, for example, 90 degrees, so as to form the hook portion 32.

As an alternative embodiment, the operating handle is in threaded connection with the top end of the vertical rod.

As an alternative embodiment, a reset-type indexing pin 34 is installed on the side surface of the connecting cross beam in the radial direction of the vertical rod, and is matched with a pin hole radially formed on the vertical rod.

As an alternative embodiment, the support legs comprise two first support legs 6 and two second support legs 7; the two first support legs are arranged at intervals relative to the two second support legs, and when the two first support legs are in contact with the horizontal plane, the bottom ends of the two second support legs are away from the horizontal plane by a certain distance and are not in contact with the horizontal plane.

Under the technical scheme, the ladder can be a ladder with inconsistent supporting legs as shown in the figure, so that the ladder can be conveniently matched and connected with a step-type grating platform.

As an alternative embodiment, a movable leg 5 is mounted in each of the two first support legs. The movable supporting leg is sleeved in a cavity in the first supporting leg, so that the length or height of the first supporting leg is increased.

As an alternative embodiment, the movable leg is locked to the first leg by a radially arranged locking pin 8 which passes radially through corresponding holes in the movable leg and the first leg to secure them.

Wherein, the connecting beam can also be connected between the two movable legs.

When the ladder is used, a user puts the ladder on the grid plate platform, pulls out the reset type indexing pin with one hand, presses down the plum blossom handle with the other hand, rotates the plum blossom handle when the fixed hook exceeds the bottom of the grid plate, so that the fixed hook can be hooked on the vertical edge of the grid plate, and then loosens the handle; the fixed hook moves upwards automatically under the action of the pressure spring, the reset type indexing pin resets at the moment, the fixed hook can be locked, and the ladder and the platform are fixed together at the moment.

The utility model discloses a ladder and the supporting use of fixed hook, can be stable fix the ladder on the grid board, make the ladder more stable, safe. And the ladder fixing hook has simple structure and easy operation.

The utility model discloses can install the ladder fixed and will when not using the ladder on the grid the ladder with the grid separation, convenient operation, and fixed stable has important meaning.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and embellishments can be made without departing from the principle of the present invention, and these modifications and embellishments should also be regarded as the protection scope of the present invention.
