Examples

Referring to fig. 1-2, the present invention provides a knob 30 type lifting structure, which includes a fixing rod 10, a telescopic rod 20, a knob 30 and a locking block 40. The fixed rod 10 is a hollow rod, and the telescopic rod 20 is slidably connected to the inner wall of the fixed rod 10. One end of the knob 30 penetrates through the sidewall of the fixing rod 10, and one end of the knob 30 is in threaded connection with a fixture block 40 disposed in the inner cavity of the fixing rod 10, and the knob 30 is rotatably connected with the fixing rod 10. The telescopic rod 20 is provided with a concave limiting groove 21, the clamping block 40 is a convex clamping block 40, and the convex clamping block 40 is matched with the concave limiting groove 21. The convex fixture block 40 comprises a block body 41 and a protrusion 42, wherein the block body 41 is partially positioned in the limiting groove 21 and clamped, and the protrusion 42 of the fixture block 40 is positioned at the opening of the limiting groove 21 and is in threaded connection with the knob 30. When the knob 30 is rotated, the block 41 of the fixture block 40 cannot rotate in the limiting groove 21, and at this time, the fixture block 40 moves close to or away from the telescopic rod 20 along with the rotation of the knob 30, so that the telescopic rod 20 can be fixed at any position after being extended for a certain length, and the extension and the fixation of the telescopic rod 20 are further realized.

The outer wall of the knob 30 is typically knurled to provide greater friction between the knob 30 and the operator's finger when turning the knob 30, thereby facilitating turning of the knob 30.

Referring to fig. 3 and 4, the opening width of the limiting groove 21 is greater than the width of the protrusion 42 of the latch 40, the width of the limiting groove 21 is matched with the width of the block 41 of the latch 40, and at this time, the latch 40 cannot rotate under the limiting of the limiting groove 21. The thickness of the block 41 of the latch 40 should be smaller than the depth of the limiting groove 21, so that the latch 40 can move up and down in the depth direction of the limiting groove 21, and further lock and release the telescopic rod 20.

It should be noted that the height of the protrusion 42 is generally lower than the opening height of the stopper groove 21 so that the latch 40 can normally move up and down.

Further, the fixture block 40 is usually made of polyoxymethylene, and the friction between the block 41 of the polyoxymethylene fixture block 40 and the connection part of the telescopic rod 20 is extremely low, so that the telescopic rod 20 can be smoothly extended.

In order to facilitate the knob 30 type lifting structure to be conveniently mounted on other devices or structures, a mounting seat 60 and a connecting block 50 are disposed at one end of the fixing rod 10, a mounting seat 60 and a connecting block 50 are disposed at one end of the telescopic rod 20, the mounting seat 60 and the connecting block 50 are rotatably connected, and the two connecting blocks 50 are respectively fixedly connected with the telescopic rod 20 or the fixing rod 10.

When the knob 30 type lifting structure is required to be connected with other structures or devices, the mounting seat 60 at one end of the fixing rod 10 is connected with an object, the mounting seat 60 at one end of the telescopic rod 20 is connected with another object, and the distance between the two objects can be controlled through the movement of the telescopic rod 20 and the matching of the knob 30 and the fixture block 40.

In order to make the angle between the object of connecting in telescopic link 20 and dead lever 10 adjustable, mount pad 60 includes pedestal 61 and pivot 62, and the both sides of pedestal 61 are provided with the mounting hole to the both sides of pivot 62 are provided with the ruled knurling, and pivot 62 can firmly combine the inner wall at the mounting hole, and pivot 62 is difficult for taking place relative slip and then making pivot 62 not hard up with mount pad 60, and mount pad 60 can be more of a specified duration to telescopic link 20 pivoted time this moment.

Referring to fig. 5, the rotation shaft 62 includes a first portion 621, a second portion 622, and a third portion 623 that are sequentially connected end to end and have sequentially decreasing outer diameters, and knurling is provided on the first portion 621 and the third portion 623, the decreasing outer diameters allowing the rotation shaft 62 to be more conveniently inserted into the mounting hole.

Similarly, in order to facilitate the connecting block 50 to rotate smoothly relative to the rotating shaft 62, the connecting block 50 is also made of polyoxymethylene and is used as the connecting block 50. The polyformaldehyde connecting block 50 has small friction when rotating with the rotating shaft 62, and meanwhile, damping exists between the polyformaldehyde connecting block 50 and the mounting seat 60, so that the telescopic rod 20 and the fixing rod 10 can rotate smoothly, and the telescopic rod 20 and the fixing rod 10 can bear objects with certain weight.

Referring to fig. 6-7, the present invention also discloses a support, which comprises a bottom plate 70, a placing plate 80 and the above-mentioned knob 30 type lifting structure. Wherein one end of the fixing rod 10 is connected with the bottom plate 70, and one end of the telescopic rod 20 is connected with the object placing plate 80. Loosen the fixture block 40 through the knob 30, so that the telescopic rod 20 can be extended, and then extend the telescopic rod 20 and then tightly abut the fixture block 40 on the telescopic rod 20 through the knob 30, so that the relative distance between the object placing plate 80 and the bottom plate 70 can be changed, and the bracket can be suitable for more scenes.

When one end of the fixing rod 10 is provided with the mounting seat 60 and the connecting block 50, and one end of the telescopic rod 20 is provided with the mounting seat 60 and the connecting block 50, the object placing plate 80 and the bottom plate 70 of the bracket can rotate relatively, the object placing plate 80 can rotate to a proper angle and height, and the application range of the bracket is further widened.

Specifically, the lower portion of the object placing plate 80 is bent to form a bent portion 81, and the bent portion 81 is used for supporting an object. The bending portion 81 is typically bent 90 °, i.e. the bending portion 81 is perpendicular to the main portion of the object placing plate 80. At this time, the bent portion 81 can satisfactorily support the object placed on the placement board 80.

The object placing plate 80 is further provided with heat dissipation holes 82, the heat dissipation holes 82 are formed in the main body position of the object placing plate 80, the heat dissipation holes 82 correspond to heat dissipation areas of placed objects such as a notebook computer or a tablet computer, and normal heat dissipation of placed products is not affected by the object placing plate 80.

The working surface of the object placing plate 80 (the abutting surface between the placed object and the object placing plate 80) is usually provided with a non-slip pad 83, so that the object is not easy to slip off when placed on the object placing plate 80.

Specifically, the anti-slip pads 83 are usually disposed at four corners and the bent portions 81 of the storage board 80, so that an object placed on the storage board 80 can be sufficiently contacted with the anti-slip pads 83, and the placed object can be better prevented from slipping off.

Likewise, a non-slip mat 83 is also provided on the bottom plate 70, the non-slip mat 83 being arranged to significantly reduce the grip of the lifting carriage, i.e. to prevent the carriage from slipping down in an accidental touch.

The bottom plate 70 is also typically provided with through holes for aesthetic or weight reduction purposes to make the stand lighter and more aesthetically pleasing.

The non-slip pad 83 usually selects a silica gel pad, the silica gel pad is low in price, and the softer silica gel pad can provide a good buffer for the object, so that the object is prevented from being collided and damaged.

The utility model also discloses a display, this display includes foretell link structure or foretell support of using ladder pivot 62 to this display possesses all advantages of using the link structure of ladder pivot 62 or support.
