Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-3, the present embodiment provides a movable platform ladder for suspended ceiling construction, which includes two oppositely arranged ladder frames 1, wherein the two ladder frames 1 are approximately in an inverted U shape, and include two side diagonal rods 12 and a crosspiece 11 horizontally arranged between the two diagonal rods 12; a cat ladder 2 is respectively arranged between the two sides of the two ladder frames 1.

A platform 3 is arranged at the upper position between the two ladders 2, and a user can climb onto the platform 3 from any one ladder 2.

As shown in fig. 1, in order to enable the platform 3 to be capable of height adjustment, in this embodiment, a plurality of vertically extending guide rods 4 are fixedly arranged at the top positions of the two ladder frames 1, and the platform 3 is slidably arranged on the guide rods 4 along the axial direction of the guide rods 4, so that the platform 3 can be vertically adjusted along the guide rods 4.

At least part of the guide rods 4 are provided with supporting members which can move along the axial direction of the guide rods 4, the supporting members can be locked relative to the guide rods 4, and the platforms 3 are stacked on the tops of the supporting members and supported by the supporting members.

It can be seen that the platform 3 is supported by the carrier, in other words, the platform 3 sits directly on the carrier under its own weight, and the platform 3 will not drop down as long as the carrier is locked so as to be kept stationary; in actual use, the height of the platform 3 is correspondingly adjusted as long as the user adjusts the height of the carrier vertically.

In this way, the user can adjust the platform 3 to an adapted height according to his own needs.

In addition, guide arm 4 not only can play the guide effect for the altitude mixture control of platform 3 in this scheme, can also play horizontal positioning effect to platform 3, can make platform 3 be difficult for taking place the skew in the horizontal direction promptly, has guaranteed the horizontal stability of platform 3 to a certain extent.

The specific structure of the carrier is as follows: as shown in fig. 1 and 2, the carrier member includes a screw sleeve 5, wherein the outer wall of a guide rod 4 provided with the screw sleeve 5 is provided with a thread section to form a screw 41, and the screw sleeve 5 is in threaded connection with the screw 41. As shown in fig. 1, in this embodiment, 3 guide rods 4 are disposed on each ladder frame 1, wherein two guide rods 4 located at two sides form the screw 41 structure, and each screw 41 is in threaded connection with a threaded sleeve 5.

When the height of the platform 3 needs to be adjusted, a user only needs to rotate the screw sleeve 5, and the screw sleeve 5 can axially move along the screw 41 so as to adjust the height of the screw sleeve 5, so that the height of the platform 3 is adjusted.

In addition, in order to facilitate the free hand rotation of the screw sleeve 5, in this embodiment, friction ridges are formed on the outer peripheral wall of the screw sleeve 5, so as to increase the friction between the hand and the screw sleeve 5 and reduce slipping.

In this embodiment, the guide rods 4 (two guide rods 4 on two sides) close to the ladder 2 form the screw 41, so that a person can conveniently stand on the ladder 2 to rotate the screw sleeve 5, and if the middle guide rod 4 is set as the screw 41, the person can not easily stand on the ladder 2 to reach the screw sleeve 5 on the screw 41.

In order to improve the connection strength of the guide rod 4, in this embodiment, a fixing rod 13 is fixedly connected to the ladder frame 1, and the upper end of the guide rod 4 is fixed to the crosspiece 11, and the lower end is fixed to the fixing rod 13.

In addition, in order to play a certain role in protecting both sides of a person when the person stands on the platform 3, in this embodiment, the two ladder frames 1 are provided with handrail members 6 which can stretch vertically, and both sides of the person are shielded and protected by the handrail members 6, so that the handrail members 6 are arranged to be vertically stretchable, and the purpose is that if the handrail members 6 cannot stretch, the height of the whole platform ladder is higher, so that the person cannot easily enter and exit the room through a door, and the handrail is arranged to be in a stretchable structure, when the person needs to enter and exit the room through the door, the handrail can be folded downwards firstly, as shown in a state shown in fig. 2, and the height of the whole platform ladder is lowered at the moment, so that the person can conveniently pass through the door; when in use, the armrest piece 6 is lifted up again, as shown in fig. 1.

The specific structure of the handrail member 6 is that the handrail member 6 includes a telescopic rod 61 and a stop rod 62, the telescopic rod 61 is movably arranged on the guide rod 4 along the vertical direction, in this embodiment, the telescopic rod 61 is movably arranged on the guide rod 4 of the screw 41 structure, specifically, in combination with fig. 3, a channel 411 axially penetrating the top of the crosspiece 11 is arranged in the screw 41, and the telescopic rod 61 is movably arranged in the channel 411 to realize the telescopic of the telescopic rod 61.

The stop lever 62 is horizontally fixed at the top of the telescopic rod 61, the position of the crosspiece 11 of the ladder frame 1 corresponding to the telescopic rod 61 is in threaded connection with the locking bolt 7, and the inner end of the locking bolt 7 is used for abutting against the telescopic rod 61 to lock the telescopic rod 61. When the telescopic rod 61 is required to be telescopic, the locking bolt 7 can be unscrewed, the abutting relation between the locking bolt 7 and the telescopic rod 61 is released, and the telescopic rod 61 can be freely telescopic; when the telescopic rod 61 is required to be locked, the locking bolt 7 is only required to be screwed so that the inner end of the locking bolt abuts against the outer peripheral wall of the telescopic rod 61.

In addition, the entire ladder frame 1 is moved for convenience. In this embodiment, rollers 8 are disposed at the bottoms of the two ends of the ladder frame 1, and the rollers 8 are preferably universal rollers with brake self-locking structures.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
