Surge guard.
According to the work characteristics of limiter, limiter design faces following demand:
A. due to the uncertainty in external impact direction, equipment usually requires to carry out impacting in three orthogonal directions anti-
Shield needs limiter to have three-dimensional limit function, and otherwise multiple unidirectional limiters will occupy a large amount of installation space；
B. due to the uncertainty of external impact amplitude, also there is certain error in design limiter time limit interdigit gap.Limit
After the device installation of position, need to adjust limit gap according to the actual situation.Simultaneously as the inconsistency of three-dimensional impact amplitude, three-dimensional
Limit gap need independent adjustment；
C. after equipment runs a period of time, due to vibration isolator creep etc., the position of equipment may change, limit
The limit gap of position device needs corresponding adjustment, and otherwise limiter can weaken or lose surge guard effect.
Currently, existing bump leveller can not meet the above demand simultaneously.
Utility model content
In view of this, the present invention provides a kind of adjustable limiters in three-dimensional gap, can be realized three direction limits

A kind of adjustable limiter in three-dimensional gap, the limiter include upper cover plate, lower cover plate, upper plate, lower plate outer cylinder, core bar
And gag lever post；
The core bar is made of two sections of different cylindrical bodies of diameter, and the outer circle of small cylinder upper end has and upper plate center screw thread
The external screw thread of hole cooperation has the radial screw bore with gag lever post cooperation on the outer circumference surface of big cylindrical body；
There is the internal screw thread with the cooperation of lower plate external screw thread on the inner peripheral surface of the outer cylinder bottom, is between lower plate and lower cover plate
Agree with assembly；
Integral assembling is in outer barrel after connecting gag lever post on the big cylindrical body excircle of the core bar；The upper end of core bar is logical
It crosses screw thread to connect with upper plate, lower plate is connected by the internal screw thread of external screw thread and outer cylinder on its outer circumference surface, rotation core bar adjustment
Vertical gap between core bar and outer cylinder；Rotate the vertical gap between lower cover plate adjustment core bar and lower plate；Rotary spacing bar tune
Lateral clearance between whole core bar and outer cylinder；Adjustment is completed rear upper plate and is fixed with upper cover plate, and bottom surface and the lower cover plate of outer cylinder are fixed.
Further, agreeing between the lower plate and lower cover plate is fitted by the hexagonal through-hole and lower cover at lower plate center
The hexagonal bolt head of plate upper surface, which cooperates, to be realized.
Further, spacing collar is installed on the bottom surface of the core bar and step surface, the surface of the spacing collar is arc
Face.
Further, the surface of the gag lever post is arcwall face.
The utility model has the advantages that
The utility model adjusts the vertical gap between core bar and outer cylinder by rotation core bar, and rotation lower cover plate adjusts core bar
Vertical gap between lower plate, rotary spacing bar adjust the lateral clearance between core bar and outer cylinder；Therefore simultaneously there are three tools
The function in directionally independent adjustment limit gap, limiter compact overall structure, good environmental adaptability are widely portable to equipment
Surge guard.
