Those of ordinary skill in the art can understand the specific meanings of the above terms in the present invention in specific situations.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Example 1

As shown in Figure 1-9, a multifunctional escalator for interior decoration includes a panel 1. The panel 1 is a square wooden board with a thickness of 3-4cm, which is light in weight and has good load-bearing capacity. The four corners of the lower end surface of the panel 1 The base 8 is fixed by bolts, and the four bases 8 are located on the same circumference. The base 8 is an aluminum alloy part, which is light in weight and easy to process. Straight down, the angle between the inner end wall and the outer end wall of the opening 801 is 20°, the symmetrical plane of the opening 801 passes through the center line of the panel, the upper end of the opening 801 is a cavity 802, and the lower end of the base 8 is equipped with two-stage telescopic rods 2. The telescopic rod 2 includes an outer tube 201. The outer tube 201 is pierced with an inner rod 202. The inner rod 202 and the outer tube 201 are in clearance fit. In order to ensure the strength and reduce the weight, the outer tube 201 is an aluminum alloy square tube with a wall thickness of The inner rod 202 is also an aluminum alloy square tube with a wall thickness of 3 mm. The upper end of the inner rod 202 is welded and fixed with a ball head 204. The ball head 204 is installed in the cavity 802. The inner rod 202 extends downward through the opening 801. The rod 202 can swing along the opening 801 , and the gap between the inner rod 202 and the side wall of the opening 801 prevents shaking.

A telescopic sleeve device is installed between two adjacent outer tubes 201. The telescopic sleeve device includes a first telescopic sleeve 3 whose two ends are hinged to the upper end of the outer tube. The telescopic sleeve device also includes two ends hinged to the middle of the outer tube. position, the second telescopic sleeve 4 includes a base pipe 401, and rods 402 are installed in both ends of the base pipe 401. Since the telescopic sleeve device is used as a beam of an escalator during use, The inner cavity section of the base pipe 401 is rectangular, and the two ends of the cross-section are arc-shaped. The base pipe 401 is made of stainless steel, with patterns on the surface, and the wall thickness is 3mm. A vertical strip-shaped through-hole 203 is opened at a position corresponding to the rod 402, and the connecting plate 5 pointing to the rod is welded and fixed on both sides of the long-strip-shaped through-hole 203, and the end of the rod 402 is welded with an upward bending part 403. The included angle between the bending part 403 and the rod 402 is 90-130°, and in this embodiment it is specifically 120°. The joint between the bending part 403 and the rod 402 is equipped with a pin shaft 6, and the two ends of the pin shaft 6 are mounted on the connection. On the plate 5, when the second telescopic sleeve 4 is stretched, the end of the bent part 403 can pass through the elongated through hole 203 and extend into the inner cavity of the outer tube 201, and the outer end of the bent part 403 is arc-shaped.

In this embodiment, the difference between the first telescopic sleeve 3 and the second telescopic sleeve 4 is that the outer end of the rod of the first telescopic sleeve 3 is not equipped with a bending portion, and the outer tube 201 is connected to the first telescopic sleeve 3 . There is no long strip-shaped through hole at the corresponding position,

The cross section of the rod 402 is rectangular, the inner end of the rod is provided with a groove 404, and a stop pin 7 is installed on the outer wall of the base pipe corresponding to the groove. After the installation is completed, the inner end of the stop pin is located in the groove and does not contact the bottom surface of the groove.

The usage principle of this embodiment is as follows:

When used as a table, the four telescopic rods are vertically downward. At this time, the inner rods are attached to the inner end wall of the opening, the rods are in line with the connecting plate, and the outermost side of the bending part is even with the inner wall of the outer tube. The telescopic rods cannot be Pull outward to ensure the stability during use. When moving, both the first telescopic sleeve and the second telescopic sleeve can be moved, which is convenient for movement.

When using it as an escalator, pull up the desktop until the lower end of the inner rod moves to the upper side of the bending part. At this time, pull the outer tube outward. Since the four outer tubes are linked by the telescopic sleeve device, the four outer tubes move evenly Swing outward until the stop pin is pressed against the inner end wall of the groove to obtain an escalator capable of climbing in four directions, and the outer end of the bending part extends through the elongated through hole to the inner cavity of the outer tube.

In addition, it is worth noting that in this embodiment, when used as an escalator, the operator can stand on the panel, which has a high safety factor.

After a long time of use, due to wear and deformation, when used as an escalator, the inner rod will move downward along the outer tube. At this time, the bending part can prevent the inner rod from continuing to move downward to ensure the normal use of the escalator. In order to prevent the lower end of the inner rod Deformation, the lower end of the inner rod is also fixed with a short square tube 205 made of stainless steel, the cross section of the short square tube is the same as the cross section of the inner rod.

It should also be noted that the angle between the inner end wall and the outer end wall of the opening is 20°. When any telescopic sleeve device is damaged, the telescopic rod swings outward until the inner rod fits with the outer end wall of the opening, and then stops. Swing, that is, the escalator will not continue to fall, has a very good safety effect.

After being used as an escalator, push the telescopic rod inward until the inner rod fits the inner end wall of the opening, and the panel drives the inner rod to fall to obtain the table state.

In order to ensure the safety of use, when changing from the table form to the escalator form, first lift the tabletop to the upper side of the bending part, pull the telescopic rod 2-3° outward, and press the panel down at this time, due to the processing tolerance and the material itself Elasticity, the panel can move down to contact with the bending part. At this time, continue to pull the telescopic rod outward until the stop pin is pressed against the inner end wall of the groove to obtain an escalator shape. At this time, the telescopic rod can no longer be shortened. Safety factor.

Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still It is possible to modify the technical solutions recorded in the foregoing embodiments, or to perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. within the spirit and principles of the present invention shall be included in the within the protection scope of the present invention.
