Abstract
The utility model belongs to a quick adjustment jack, wherein, the middle part of an adjusting rod is provided with a cross hole for inserting a pulling lever; the wall of each of the adjusting rods arranged at both ends of the cross hole is provided with left thread and right thread which are screwed up with a pressing nut, a locknut, a locking nut and a base; moreover, the left thread and the right thread are reverse threads. The utility model has the advantages of a simple structure, convenience for use, high safety and reliability and quick adjustment.
Description
Technical field
The utility model belongs to a kind of velocity modulation jack.
Background technology
At present, both at home and abroad need use jack in the adjustment of horizontal adjustment, displacement and the various well lids of machinery manufacturing industry, remanufactured-vehicle business, building industry, large-scale, ultra-large type base part etc., jack is widely used, yet, in the majority at jack commonly used with hydraulic type, spiral hydraulic type jack.These two kinds of jack manufacturing process complexity, the cost height, use inconvenient, the time have release and slide fastener phenomenon that the hidden danger that causes the accident takes place.
Summary of the invention
The purpose of this utility model is a kind of velocity modulation jack of design, has simple in structure, esy to use, safe and reliable and the quick-adjustsing advantage of energy.
For this reason, the cross bore of inserting for moving bar is established at adjusting lever of the present utility model middle part, the adjusting lever perisporium at cross bore two ends is provided with left and right screw thread, left and right screw thread on the adjusting lever is spirally connected successively from top to bottom and holds out against nut, black nut, jam nut and base, and described left and right screw thread is a reverse thread.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that: simple in structure, esy to use, safe and reliable and energy quick adjusting.
Description of drawings
Figure is a structural representation of the present utility model
Specific embodiments
As shown in the figure, a kind of velocity modulation jack is by base 1, jam nut 2, adjusting lever 3, black nut 4, hold out against nut 5 and moving rod 6 is formed.The cross bore of inserting for moving bar is established at the adjusting lever middle part, the adjusting lever perisporium at cross bore two ends is provided with left and right screw thread, left and right screw thread on the adjusting lever is spirally connected successively from top to bottom and holds out against nut, black nut, jam nut and base, and described left and right screw thread is a reverse thread.
Obviously, the perisporium of the cross bore of adjusting lever upper end is provided with left-hand thread, and being spirally connected successively from top to bottom on the left-hand thread holds out against nut and black nut.The perisporium of the cross bore lower end of adjusting lever is provided with right-hand thread, and jam nut and base from top to bottom successively are spirally connected on the right-hand thread.
During use, with base with hold out against nut and put on ground and between by the jack-up thing, in the cross bore that moving bar inserts, the rotation moving bar drives the adjusting lever rotation, make the left and right threads turn on the adjusting lever make base and hold out against the reverse left and right screw thread that is provided with in nut edge to adjusting lever two ends inverted running, finishing lifting is put in place by the jack-up thing, after being put in place by the jack-up thing, respectively black nut and jam nut are gone to hold out against nut and base bottom and hold along left and right screw thread and fixedly hold out against nut and base on adjusting lever.Finish lifting by the jack-up thing.Otherwise, then reduce by the jack-up thing, so be not repeated.
In a word, the utlity model has simple in structure, esy to use, safe and reliable and the quick-adjustsing advantage of energy, can promote the use of.
