Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, the present solution provides an embodiment: a small bed table with adjustable height comprises a table top 1, wherein the front and the back of the bottom of the table top 1 are respectively provided with a first chute 5 along the length direction, two sliders 4 are arranged inside the first chutes 5 in a sliding manner, racks 3 are fixedly connected to the bottoms of the sliders 4, a connecting plate 15 is fixedly connected to one side of each of the two racks 3 close to each other, the top of the connecting plate 15 is fixedly connected with the inner wall of the top of the first chute 5, two bidirectional screws 7 are rotatably connected inside the two connecting plates 15, a protective frame 10 is fixedly connected to the bottom of the table top 1, two support rods 13 are hinged inside the bottoms of the two sides of the protective frame 10, rotating shafts 9 are fixedly connected to the tops of the two support rods 13 on the left side and the right side, half gears 2 are fixedly sleeved outside the front and the back of the rotating shafts 9, the half gears 2 are meshed with the racks 3 for transmission, and protective rods 11 are slidably sleeved outside the support rods 13, the guard bar 11 is provided with a second sliding groove along the height direction thereof, and the support bar 13 is slidably mounted inside the second sliding groove.
In this embodiment, a plurality of circular through holes 14 are all opened in the inside of bracing piece 13, and the inside of fender rod 11 is equipped with bolt 12, and bolt 12 threaded sleeve is established in the inside of circular through hole 14.
In this embodiment, the external fixation cover of the bidirectional screw 7 is provided with a protection sleeve 6, and the external of the protection sleeve 6 is provided with anti-skid lines.
In this embodiment, the left side of the bidirectional screw 7 is fixedly connected with the stop block 8, and the vertical sections of the first chute 5 and the slide block 4 are both in a T-shaped structure.
In this embodiment, the two-way screw 7 is located inside the protection frame 10, and the cross section of the table top 1 is a rectangular structure.
In this embodiment, the number of the circular through holes 14 is three, and the circular through holes 14 are respectively formed on the sides of the two support rods 13 away from each other.
The working principle is that firstly, the protective sleeve 6 is rotated, the rotation of the protective sleeve 6 can drive the two-way screw 7 to rotate, under the limit of the first chute 5 to the connecting plate, the rotation of the two-way screw 7 can drive the two connecting plates 15 to approach or separate from each other, the approach or separation of the two connecting plates 15 can drive the left and right racks 3 to approach or separate from each other, the approach and separation of the left and right racks 3 can drive the half gear 2 and the rack 3 to carry out meshing transmission, further, the half gear 2 can also rotate, the rotation of the half gear 2 can drive the supporting rod 13 to rotate, the rotation of the supporting rod 13 can adjust a certain angle, and meanwhile, the bolt 12 is rotated, so that the supporting rod 13 can longitudinally slide in the protective rod 11, further, the height of the desktop 1 can be adjusted, the use of a user is more convenient, and through the arrangement of the rack 3, the two-way screw 7 and the like, the angle of two bracing pieces 13 can be adjusted in the rotation of two-way screw 7, rotates bolt 12, can make bracing piece 13 slide in the inside of protection rod 11, and then adjusts the height of desktop 1, has made things convenient for the use more.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
