Description
Technical field
The convenient chin bracket regulating height, relates to technical field of living goods, particularly relates to a kind of chin bracket.
Background technology
Be sitting in the office staff of office edge of table for a long time, be sitting in the personnel of the inteilectual before desk and Long-Time Service computer for a long time, head can feel unable, sometimes can only live with hand rest, can affect working and learning efficiency like this, and the cervical spondylosis that is easy to get.
Summary of the invention
The object of the invention is the deficiency in order to overcome above-mentioned present situation, a kind of convenient chin bracket regulating height is provided.
A kind of convenient chin bracket of height that regulates mainly comprises U-shaped holder, support bar and base plate.U-shaped holder adopts plastics or metal material to make.U-shaped holder is connected by support bar with base plate.Support bar comprises movable ratch, fixing square tube and height adjustment mechanism.Movable ratch upper end is fixed on below U-shaped holder, and fixing square tube lower end is fixed on the center of base plate.Movable ratch inserts in fixing square tube.Leaving a blank a breach in right side in the middle part of fixing square tube, facilitates the left-hand component of gear to enter in fixing square tube and engage with the straight-tooth of movable ratch.Height adjustment mechanism comprises stem gear, gear handle, support, positioning ejection reed and spring leaf shadoof.Gear handle and gear are fixed on one end of gear shaft coaxially, and the other end of gear shaft is arranged on right section of support by oilless bearing, and the left end of support is vertical with fixing square tube to be connected.Rotate clockwise gear handle movable ratch can be made to increase thus promote U-shaped holder to raise.The left end of positioning ejection reed is fixedly mounted in fixing square tube, and installation site is higher than gear, and positioning ejection reed tilts to the right, and the right-hand member of positioning ejection reed is pressed on the top tooth of gear, prevents gear from rotating counterclockwise, and namely prevents movable ratch automatic descending.If need reduce movable ratch, should mention spring leaf shadoof, unclamp the constraint of positioning ejection reed to gear, transmitting gear then can make movable ratch decline counterclockwise.
This convenience regulates the chin bracket of height that cervical vertebra can be made to keep normal position and not bending especially, can also alleviate neck fatigue, be conducive to healthy.If pad in U-shaped holder Heat-insulation cloth also can cold-proof guarantor dim.This convenience regulates the chin bracket of height to be applicable to the librarian use before being sitting in platform for a long time; Also be suitable for medical, be used as to correct cervical vertebra; Also be applicable to disabled person to drink water uses, water tumbler be placed in the front of this bracket, with suction pipe water suction, conveniently to locate.
Accompanying drawing explanation
Fig. 1 is a kind of convenient schematic diagram regulating the chin bracket of height of the present invention; Fig. 2 is the partial enlarged drawing at height adjustment mechanism position in Fig. 1.
In figure: 1-U shape is held in the palm; 2-support bar, the movable ratch of 21-, 22-fixes square tube; 3-base plate; 4-height adjustment mechanism, 41-gear, 42-gear handle, 43-support, 44-positioning ejection reed, 45-spring leaf shadoof.
Detailed description of the invention
Below in conjunction with accompanying drawing, 1 ~ 2 couple of the present invention is illustrated.
A kind of convenient chin bracket of height that regulates mainly comprises U-shaped holder 1, support bar 2 and base plate 3.U-shaped holder 1 adopts plastics or metal material to make, and outsourcing fabric, fabric adopts cloth or cladding.U-shaped holder 1 can make different specification forms according to the chin shape of different people.U-shaped holder 1 is connected by support bar 2 with base plate 3.Support bar 2 comprises movable ratch 21, fixing square tube 22 and height adjustment mechanism 4.Movable ratch 21 upper end is fixed on below U-shaped holder 1, and fixing square tube 22 lower end is fixed on the center of base plate 3.Movable ratch 21 inserts in fixing square tube 22.Leaving a blank a breach in right side in the middle part of fixing square tube 22, facilitates the left-hand component of gear 41 to enter in fixing square tube 22 and engage with the straight-tooth of movable ratch 21.Height adjustment mechanism 4 comprises stem gear 41, gear handle 42, support 43, positioning ejection reed 44 and spring leaf shadoof 45.Gear handle 42 and gear 41 are fixed on one end of gear 41 axle coaxially, and the other end of gear 41 axle is arranged on right section of support 43 by oilless bearing, the left end of support 43 is vertical with fixing square tube 22 to be connected.Rotate clockwise gear handle 42 movable ratch 21 can be made to increase thus promote U-shaped holder 1 to raise.The left end of positioning ejection reed 44 is fixedly mounted in fixing square tube 22, installation site is higher than gear 41, and positioning ejection reed 44 tilts to the right, and the right-hand member of positioning ejection reed 44 is pressed on the top tooth of gear 41, prevent gear 41 from rotating counterclockwise, namely prevent movable ratch 21 automatic descending.If need reduce movable ratch 21, should mention spring leaf shadoof 45, unclamp the constraint of positioning ejection reed 44 pairs of gears 41, transmitting gear 41 can make movable ratch 21 decline counterclockwise.Base plate 3 is rectangle.
