Description
Technical field
The present invention relates to jacking, hanging device technical field, specifically a kind of socket trapezoidal screw Anti-blocking structures.
Background technique
Existing socket trapezoidal screw stall form is mostly that nature is stuck, unshielded measure, and screw rod is rotated by trapezoidal thread
Driving torque, in extreme position since second level screw rod still needs to be driven, so that level-one trapezoidal screw is with nut thereon because of transmitting
Torque is excessive and stuck phenomenon easily occurs.Therefore it is badly in need of a kind of stall structure that can more reasonably transmit torque, makes trapezoidal thread
Will not be excessive and stuck because of torque, cause nut that can not exit.
Summary of the invention
The technical problems to be solved by the present invention are: providing socket trapezoidal screw Anti-blocking structure, can effectively avoid being socketed
Screw rod is stuck, the friction between screw rod is reduced, to increase the service life of screw rod.
The technical solution used in the present invention is: it includes level-one trapezoidal screw, copper spiral shell is arranged with outside level-one trapezoidal screw
Mother, copper nut are threadedly coupled with level-one trapezoidal screw, are arranged with second level screw rod outside level-one trapezoidal screw, second level screw rod bottom end passes through
Axle sleeve offsets with copper nut, and copper nut is equipped with step surface towards the end face of level-one trapezoidal screw, and the end face of level-one trapezoidal screw is set
There is the step surface that can be mutually fitted into therewith, the end face of level-one trapezoidal screw is equipped with the step surface that can be mutually fitted into therewith, level-one ladder
Shape screw rod and copper nut are equipped with several grooves on the end face of step surface, and groove extends radially through, the same step of trench depth
Face height, groove opening size are bigger than bottom.
Preferably, outer tube is arranged with outside level-one trapezoidal screw.
Preferably, outer tube end is equipped with guide sleeve, for fixing level-one trapezoidal screw end.
Preferably, copper nut bottom end end face is equipped with pedestal.
Preferably, axle sleeve is sheathed on copper nut.
Preferably, several grooves are equidistantly distributed in level-one trapezoidal screw and copper nut on the end face of step surface.
The present invention is socketed trapezoidal screw Anti-blocking structure, and advantage is as follows: copper nut is trapezoidal as anti-jamming mechanism and level-one
The mutually chimeric stall face formed between screw rod, not only avoids stall stuck phenomenon, and level-one trapezoidal screw is passed
The efficiency for passing torque to second level screw rod greatly increases, and hard friction is greatly decreased, and screw rod uses trapezoidal screw, and trapezoidal screw has
Certain self-locking performance；It is equipped with groove on the end face of step surface, so that the step surface phase of copper nut and level-one trapezoidal screw
It can play a buffer role in when hitting, groove number more than one, the purpose designed in this way is, since step surface collides, and not
It is disconnected to be squeezed and deform, so that the size of groove slowly becomes smaller, it is several below if the groove near step surface is closed completely
Groove can continue to work as a buffer, in addition, groove opening size is greater than bottom size, so that groove is in reverse trapezoid shape, and this
Just similar to dykes and dams, shock resistance or extrusion capability is greatly enhanced in sample.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, the present invention provides socket trapezoidal screw Anti-blocking structure, it includes level-one trapezoidal screw 1, and level-one is trapezoidal
It is arranged with copper nut 2 outside screw rod 1, copper nut 2 is threadedly coupled with level-one trapezoidal screw 1, and the rotation of level-one trapezoidal screw 1 drives copper spiral shell
Mother 2 moves up and down along level-one trapezoidal screw 1, and second level screw rod 3 is arranged with outside level-one trapezoidal screw 1, and 3 bottom end of second level screw rod is logical
It crosses axle sleeve 7 to offset with copper nut 2, as shown in Fig. 2, copper nut 2 is equipped with step surface 4, level-one towards the end face of level-one trapezoidal screw 1
The end face of trapezoidal screw 1 is equipped with the step surface 4 that can mutually be fitted into therewith, when level-one trapezoidal screw 1 and copper nut 2 reach capacity position
When setting, 1 step surface of level-one trapezoidal screw and the step surface 4 of copper nut 2 overlap, to realize torque transmission effect.
Level-one trapezoidal screw 1 and copper nut 2 are equipped with several grooves 10,10 diameter of groove on the end face of step surface 4
To running through, for 10 depth of groove with step surface height, 10 opening size of groove is bigger than bottom, when two step surfaces 4 bump against, groove 10
The impact force to step surface 4 can be effectively buffered, the deformation of step surface 4 is reduced, it is final to reduce copper nut 2 and level-one trapezoidal screw 1
Torsional pulse power, thus the service life both improved.
2 bottom end end face of copper nut is equipped with pedestal, and axle sleeve 7 is sheathed on copper nut 2, and pedestal holds axle sleeve 7, when pedestal with
When copper nut 2 moves up, axle sleeve one end resists copper nut, and the other end resists second level screw rod end, and axle sleeve is also therewith to moving up
It is dynamic, so that second level screw rod 3 be pushed to also move up, it is arranged with protruded tube 8 outside second level screw rod 3, protruded tube 8 is with second level screw rod 3
Jacking upwards.
