The specific embodiment
Below in conjunction with Figure of description the utility model is done further description.
Shown in Fig. 1-3; The described tables and chairs lowering or hoisting gear of the utility model embodiment; Assembled by lifters that cooperatively interacts 1 and installed part 2, lifters 1 is T type structure with installed part 2, on the web of lifters 1, has hole 3; Its web inside is hollow shape, and installed part 2 tops are placed in the lifters 1; On the web of installed part 2, have through hole 5, this through hole 5 comprises some manholes 51 vertically arranged in a uniform and the square through hole 52 that is communicated with adjacent two manholes 51, and wherein, the length of said square through hole 52 is less than the diameter of manhole 51.Also comprise a peg button 4, an end of this peg button 4 is located in the above-mentioned hole 3, and is movably connected in the through hole 5 on the installed part 2, flexibly connects with installed part 2.
As shown in Figure 4; Said peg button 4 comprises fixture 41, spring 42 and button 43; The cross section of fixture 41 is I-shaped, and it is made up of first cylinder 411, second cylinder 412 and the joint pin 413 that connects first cylinder 411 and second cylinder 412, wherein; Said second cylinder 412 connects spring 42, and spring 42 connects button 43.
The diameter of manhole 51 is corresponding on the bottom surface diameter of said first cylinder 411 and the installed part 2; The bottom surface diameter of joint pin 413 is less than the length of square through hole 52 on the installed part 2.
Like Fig. 5, shown in Figure 6, during normal condition, first cylinder 411 is arranged in the manhole 51, and when pressing the button 43, button 43 exerts pressure for fixture 41 through spring 42, and first cylinder 411 is extruded from manhole 51; This moment, lifters 1 was an active state with installed part 2; Scalable peg button 4; Joint pin 413 is moved in another manhole 51 along square through hole 52 up or down, decontrol button 43 subsequently, fixture 41 ejects; This moment, first cylinder 411 was arranged in the above-mentioned manhole 51 automatically, thereby had realized the liter of desk and chair or fall.Simple in structure, easy to operate, device stability is strong, and does not have any noise.
More than; Be merely the preferred embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claim was defined.
