Utility model content
The technical problems to be solved in the utility model is, for the drawbacks described above of prior art, there is provided a kind of regulation side
Become this low projecting apparatus and easily adjust leg.
Technical scheme is used by the utility model solves its technical problem：
Construct a kind of projecting apparatus and easily adjust leg, including projecting apparatus；Wherein, the projecting apparatus lower surface is close to front end both sides
Leg is provided with angle；The leg includes reciprocating screw rod, and the reciprocating screw rod includes screw axis and feed screw nut；The throwing
Blind hole corresponding with the screw axis is provided with shadow instrument；Described screw axis one end is goed deep into inside the blind hole, and the other end rotates
It is connected with feet；The blind hole opening is provided with the annular groove coordinated with the feed screw nut, and the annular groove bottom is set
There is ball and accommodate the cavity of the ball；The projecting apparatus lower surface sets the spacing limited block of the promising feed screw nut；
Also include corresponding described in the motor set, the power supply for motor power supply and control with the feed screw nut
The toggle switch of motor power on/off.
Projecting apparatus described in the utility model easily adjusts leg, wherein, the projecting apparatus upper surface be provided with air level and
The mounting groove of the air level is installed.
Projecting apparatus described in the utility model easily adjusts leg, wherein, the feet bottom is provided with silica gel sheath.
The beneficial effects of the utility model are：When needing regulation, it is powered by stirring toggle switch motor
Rotate, the motion of drive screw nut so that projecting apparatus prolongs screw axis motion, reaches the purpose of regulation, and easy to adjust and structure is simple
Single, cost is low；Coordinated by ball and feed screw nut, limited block is spacing to feed screw nut, avoids feed screw nut and projecting apparatus machine
Shell directly rubs, compact-sized, and it is small to take projecting apparatus inner space.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below in conjunction with accompanying drawing and reality
Applying example, the utility model is described in further detail, and drawings in the following description are only the section Example of the present invention, for this
For the those of ordinary skill of field, on the premise of not paying creative work, it is attached other can also to be obtained according to these accompanying drawings
Figure：
Fig. 1 is that the projecting apparatus of the utility model preferred embodiment easily adjusts stand bar structure schematic diagram.
Embodiment
In order that the purpose, technical scheme and advantage of the utility model embodiment are clearer, below in conjunction with this practicality
Technical scheme in new embodiment carries out clear, complete description, it is clear that described embodiment is portion of the present utility model
Divide embodiment, rather than whole embodiments.Based on embodiments of the invention, those of ordinary skill in the art are not paying creation
Property work on the premise of the every other embodiment that is obtained, belong to the scope of protection of the utility model.
The projecting apparatus of the utility model preferred embodiment easily adjusts leg as shown in figure 1, including projecting apparatus 1, under projecting apparatus 1
Surface is provided with leg 10 close to the edge of front end two；Leg 10 includes reciprocating screw rod 100, and reciprocating screw rod 100 includes screw mandrel
Axle 101 and feed screw nut 102；Blind hole 11 corresponding with screw axis 101 is provided with projecting apparatus 1；The one end of screw axis 101 is goed deep into blind
Inside hole 11, the other end is rotatably connected to feet 12；The opening of blind hole 11 is provided with the annular groove coordinated with feed screw nut 102
13, the bottom surface of annular groove 13 is provided with ball 130 and accommodates the cavity 131 of ball 130；The lower surface of projecting apparatus 1 sets promising screw mandrel
The spacing limited block 14 of nut 102；Also including corresponding the motor 15 set with feed screw nut 102, being motor
The power supply (not shown) of 15 power supplies and the toggle switch 16 of the control power on/off of motor 15；When needing regulation, by dialling
Dynamic toggle switch 16 causes motor 15 is powered to rotate, and drive screw nut 102 moves so that projecting apparatus 1 prolongs screw axis 101
Motion, reaches the purpose of regulation, easy to adjust and simple in construction, cost is low；Coordinated by ball 130 and feed screw nut 102, limited
Position block 14 is spacing to feed screw nut 102, avoids feed screw nut 102 from directly being rubbed with the casing of projecting apparatus 1, compact-sized, accounts for
It is small with projecting apparatus inner space.
As shown in figure 1, the upper surface of projecting apparatus 1 is provided with air level 17 and installs the mounting groove 170 of air level 17, it is easy to see
Examine whether level-off, regulation is more convenient.
As shown in figure 1, the bottom of feet 12 is provided with silica gel sheath 120, bumper and absorbing shock and good antiskid effect.
