Abstract
A kind of structure of locking gap of worm, including：Worm gear for driving cloud platform rotation is rotatablely installed in holder；Worm screw fixed seat, inner rotation are equipped with worm screw, and worm and wheel is meshed, and are provided with slot hole in fixed seat, screw pass through screw after slot hole in holder；Fixed plate is fixed in holder, and N number of adjusting screw is combined in fixed plate, and N is the natural number more than or equal to 2, and the axis of adjusting screw and the axis perpendicular of worm screw, the tail end of adjusting screw are in contact with worm screw fixed seat.Worm screw fixed seat can be pushed along slot hole transverse shifting by turning adjusting screw, so that worm and wheel is in close contact, keep meshing state, under the shock environment of vibration, the gap of the worm and gear of holder will not change, so that it is guaranteed that the precision of holder operation all day.
Description
Technical field
The utility model is related to security tripod head fields, and in particular to the structure of gap of worm is locked in a kind of holder.
Background technology
Jerk is suffered from the work of security tripod head word, under jerk environment, the gap of holder worm and gear
Can be increasing with the increase of vibratory impulse, and therefore influence the precision of holder entirety.
Invention content
The utility model provides a kind of guarantee worm and gear movement clearance and keeps not to overcome the shortcomings of the above technology
The structure of the locking gap of worm of change.
Technical solution is used by the utility model overcomes its technical problem：
A kind of structure of locking gap of worm, including：
Worm gear for driving cloud platform rotation is rotatablely installed in holder；
Worm screw fixed seat, inner rotation are equipped with worm screw, and the worm and wheel is meshed, and is arranged in the fixed seat
Have a slot hole, screw pass through screw after slot hole in holder；
Fixed plate is fixed in holder, and N number of adjusting screw is combined in fixed plate, and N is the natural number more than or equal to 2, institute
The axis of adjusting screw and the axis perpendicular of worm screw are stated, the tail end of the adjusting screw is in contact with worm screw fixed seat.
Further include coaxial package in the spring in adjusting screw, one end of the spring is in contact with fixed plate, another
End is in contact with worm screw fixed seat.
Further include the plain cushion and spring washer being set between the head of screw of adjusting screw and fixed plate.
Further include the stressed plate being set in worm screw fixed seat, the tail end of the adjusting screw is in contact with stressed plate.
The utility model has the beneficial effects that：Worm screw fixed seat can be pushed along slot hole transverse direction by turning adjusting screw
It is mobile, so that worm and wheel is in close contact, keeps meshing state, thus under the shock environment of vibration, the worm and gear of holder
Gap will not change, so that it is guaranteed that the precision of operation holder all day.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 1. worm gear, 2. worm screw, 3. worm screw fixed seat, 4. stressed plate, 5. slot hole, 6. screw, 7. fixed plate 8. is adjusted
Save 9. spring of screw, 10. plain cushion, 11. spring washer.
Specific implementation mode
1 pair of the utility model is described further below in conjunction with the accompanying drawings.
A kind of structure of locking gap of worm, including：Worm gear 1 for driving cloud platform rotation, rotational installation in
In holder；Worm screw fixed seat 3, inner rotation are equipped with worm screw 2, and worm screw 2 is meshed with worm gear 1, and length is provided in fixed seat 3
Hole 5, screw 6 pass through slot hole 5 after screw in holder；Fixed plate 7, is fixed in holder, and N number of adjusting screw 8 is combined on fixation
In plate 7, N is the natural number more than or equal to 2, the axis perpendicular of the axis and worm screw 2 of adjusting screw 8, the tail end of adjusting screw 8
It is in contact with worm screw fixed seat 3.Worm screw fixed seat 3 can be pushed along 5 transverse shifting of slot hole by turning adjusting screw 8, made
Worm screw 2 is in close contact with worm gear 1, keeps meshing state, thus under the shock environment of vibration, the gap of the worm and gear of holder
It will not change, so that it is guaranteed that the precision of holder operation all day.Since adjusting screw 8 is more than or equal to 2, so as to effective
Prevent worm screw fixed seat 3 from deflecting power, it is ensured that molar behavior it is reliable.
Further, further include coaxial package in the spring 9 in adjusting screw 8, one end of spring 9 connects with fixed plate 7
It touches, the other end is in contact with worm screw fixed seat 3.Increasing spring 9 in original adjusting screw 8 can be in screw pretightning force
On the basis of be further added by initial tension of spring, even if to structure interval under vibratory impulse environment between worm gear 1 and worm screw 2
It will not change.Can also include the plain cushion 10 and spring washer 11 being set between the head of screw of adjusting screw 8 and fixed plate 7.
Adjusting screw 8 can be effectively prevent to loosen by the way that plain cushion 10 and spring washer 11 is arranged.Can also include being set to worm screw to fix
Stressed plate 4 on seat 3, the tail end of adjusting screw 8 are in contact with stressed plate 4.By the way that stressed plate 4 is arranged, can prevent from adjusting spiral shell
Nail 8 is in direct contact with worm screw fixed seat 3, causes the damage of screw holder 3.
