Technical field
The present invention relates to student appliance technical field, specially a kind of student's seat special with elevating function.
Background technology
Seat is that a kind of have the also armed thing to sit on of backrest, some.Ancient times sit on the ground, and original does not have chair, and " chair " is originally
Wooden name.High school student's upper class hour is, it is necessary to use seat, because the height of each high school student is different, so what each high school student needed
Seat height is also different, so people have invented height-adjustable seat, most of high school student's seat in the market is all
Be with hand adjustment section height, so as to waste the muscle power of high school student, and make the regulation of height of seat very inconvenient.
The content of the invention
It is an object of the invention to provide a kind of student's seat special with elevating function, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides following technical scheme:A kind of student's seat special with elevating function,
Including bottom plate, the upper surface of the bottom plate is fixedly connected with lowering or hoisting gear, and seat is fixedly connected with the top of the lowering or hoisting gear
Body.
The lowering or hoisting gear includes retractor device, and the retractor device includes housing, and the housing is internally provided with cunning
Bar, the front of the slide bar and side are fixedly connected with limited location block, and one end of the limited block is slidably connected at the interior of housing
On wall, the top of the slide bar is fixedly connected with top plate, and the lower surface of the top plate is fixedly connected with sliding bar, the sliding bar
Bottom be fixedly connected with movable pulley, the surface of the sliding bar is socketed with slip rod set, and the back side for sliding rod set is fixed
The first fix bar is connected with, one end of first fix bar is fixedly connected with the side of housing, under first fix bar
Surface is fixedly connected with the first contiguous block, and the front of first contiguous block is fixedly connected with pull rope, and the one of the pull rope
End sequentially passes through movable pulley and quiet pulley and with setting second contiguous block on electric expansion bar top to be fixedly connected, described electronic to stretch
The bottom of contracting bar is fixedly connected on the upper surface of bottom plate, and the lower surface of first fix bar is fixed with the top of quiet pulley to be connected
Connect, the sliding bar is between the first contiguous block and quiet pulley.
Preferably, the seat body includes seat support, and the front of the seat support is fixedly connected with handrail, the side of the seat support
Face is fixedly connected with the chair back, and the side of the chair back is fixedly connected with one end of handrail.
Preferably, the upper surface of the top plate is fixedly connected with the lower surface of seat support, the upper surface of the bottom plate and housing
Bottom be fixedly connected.
Preferably, the quantity of the lowering or hoisting gear is two, and two lowering or hoisting gears are fixedly connected with the upper table in bottom plate
Face, and each lowering or hoisting gear includes two retractor devices, the electric expansion bar is between two retractor devices.
Compared with prior art, the beneficial effects of the invention are as follows:This has student's seat special of elevating function, by setting
Electric expansion bar is put, shortens electric expansion bar, the second contiguous block is declined simultaneously pulling traction rope, is slided so that movable pulley drives
Lever rises, so that the height rise of seat support body, the height without high school student with hand adjustment section seat body, is reduced
The amount of labour of high school student, the muscle power of high school student is saved, make the regulation of height of seat more convenient, by setting retractor device, make
The raising and lowering of seat body is more steady, by setting movable pulley, quiet pulley and pull rope, make seat body rising and
It is more convenient to decline.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme:A kind of student's seat special with elevating function, bag
Bottom plate 1 is included, the upper surface of bottom plate 1 is fixedly connected with lowering or hoisting gear 2, by setting lowering or hoisting gear 2, makes the rising of seat body 3
More convenient with declining, the quantity of lowering or hoisting gear 2 is two, and two lowering or hoisting gears 2 are fixedly connected with the upper table in bottom plate 1
Face, and each lowering or hoisting gear 2 includes two retractor devices 201, by setting retractor device 201, make the rising of seat body 3 with
Decline is more steady, and for electric expansion bar 208 between two retractor devices 201, the top of lowering or hoisting gear 2 is fixedly connected with seat
Chair body 3, seat body 3 include seat support 31, and the front of seat support 31 is fixedly connected with handrail 32, and the side of seat support 31 is fixedly connected
There is the chair back 33, the side of the chair back 33 is fixedly connected with one end of handrail 32.
Lowering or hoisting gear 2 includes retractor device 201, and retractor device 201 includes housing 21, by setting housing 21, makes slide bar
22 more facilitate in interior slide of housing 21, and housing 21 is internally provided with slide bar 22, the front of slide bar 22 and the side company of fixation
Limited block 23 is connected to, by setting limited block 23, makes the raising and lowering of slide bar 22 more steady, one end of limited block 23 is slided
It is connected on the inwall of housing 21, the top of slide bar 22 is fixedly connected with top plate 202, upper surface and the seat support 31 of top plate 202
Lower surface is fixedly connected, and the upper surface of bottom plate 1 is fixedly connected with the bottom of housing 21, and the lower surface of top plate 202 is fixedly connected with
Sliding bar 209, by setting sliding bar 209 and sliding rod set 2010, sliding bar 209 is being slided slip in rod set 2010, make
The raising and lowering of seat body 3 is more convenient, and the bottom of sliding bar 209 is fixedly connected with movable pulley 205, by setting dynamic slide
Wheel 205, pull rope 204 is set to drive the raising and lowering of movable pulley 205 more convenient, the surface of sliding bar 209 is socketed with sliding bar
Set 2010, the back side for sliding rod set 2010 are fixedly connected with the first fix bar 2011, by setting the first fix bar 2011, make the
