Abstract
The utility model belongs to the technical field of machinery, and provides a safe high-level bracket which can prevent a screw rod from rotating along with a threaded sleeve and has the advantages of high safety performance, wide application and simple structure, so as to solve the problems of in the prior part. The technical scheme provided by the utility model is that the safe high-level bracket comprises a tubular column vertically arranged on a base plate, a threaded sleeve with a rotating handle is connected to the top of the column through a bearing, a screw rod matched with the threaded sleeve is arranged in the cavity of the column, a top tray is arranged at the top of the screw rod, an anti-rotation structure for restricting the rotation of the screw rod is arranged on the bracket and comprises a positioning groove or a positioning plane axially formed on the circumferential surface of the screw rod and a positioning pin located on the column, and the positioning pin is inserted into the positioning groove through a through hole on the column.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of high-order support, the high-order support of particularly a kind of safety.
Background technology
Support important document when high-order support generally is auto repair at present, though common vehicle support stand kind is more, is a tripod type or with the fixed of steel plate drawing or have the support of tooth bar pawl type, screw mandrel formula mostly.But the some shortcomings part that present high-order support generally all exists; Such as, regulate in the support process operating personnel, when handle rotates, screw mandrel is that the swivel nut of following on the handle rotates together, thereby can't realize the lifting effect of screw mandrel, needs like this with the fixing screw mandrel of an other hand, just can make and regulate height, potential safety hazard is so just arranged.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind ofly to avoid that screw mandrel and swivel nut rotate together, security performance height, the high-order support of safety widely applicable, simple in structure.
The purpose of this utility model can realize by following technical proposal: the high-order support of a kind of safety, comprise the pipe support that vertically is built up on the chassis, the swivel nut that is provided with turning handle is connected in the column top by bearing, be provided with in the cavity of column and the swivel nut fit screw rod, the screw mandrel top is provided with, and it is characterized in that; The anti-rotation structure that one restriction screw mandrel rotates is set on this support, and this structure comprises locating slot or the plane of orientation that axially is provided with along the screw mandrel circumferential surface, and an alignment pin that is positioned on the column, and alignment pin inserts locating slot by the through hole on the column.
Alignment pin with just realized the circumferential location of screw mandrel after locating slot or plane of orientation cooperate, but do not influence moving up and down of screw mandrel.
In the above-mentioned high-order support of a kind of safety, described through hole is a circular hole, and described alignment pin is a cylinder.
In the above-mentioned high-order support of a kind of safety, described alignment pin outer surface is provided with screw thread, and described through hole is a screwed hole.
Compared with prior art, the high-order support of safety has the following advantages: insert at alignment pin under the situation of locating slot or plane of orientation, make the rotation of screw mandrel be restricted, do not rotate with swivel nut and cause screw mandrel can't realize the result of lifting thereby screw mandrel can not occur.The utility model is relatively simple for structure in addition, service life is long, be convenient for carrying screw mandrel working stability, difficult absent-mindedness, security performance height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A place among Fig. 1.
Among the figure, 1, the chassis; 2, column; 3, bearing; 4, turning handle; 5, swivel nut; 6, screw mandrel; 7, take over a business; 8, plane of orientation; 9, alignment pin; 10, through hole.
The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, 2, the high-order support of a kind of safety comprises vertically being built up in The One On The Chassis pipe support 2 that the swivel nut 5 that is provided with turning handle 4 is connected in column 2 tops by bearing 3, be provided with in column 2 cavitys and swivel nut 5 fit screw rod 6, screw mandrel 6 tops are provided with 7; The above structure all structure in the high-order support of existing safety is identical.
The utility model offers locating slot or plane of orientation 8 at described screw mandrel 6 circumferential surfaces, and locating slot or plane of orientation 8 are along the axial setting (as seen, having formed plane of orientation 8 after the part screw thread on screw mandrel 6 surfaces is removed among the figure) of screw mandrel 6.
Column 2 is provided with alignment pin 9 and through hole 10, and alignment pin 9 inserts locating slot or plane of orientation 8 by through hole 10.Alignment pin 9 is a cylinder, and alignment pin 9 outer surfaces are provided with screw thread.When handle rotates, because alignment pin 9 inserts locating slot or plane of orientation 8, can prevent that so just screw mandrel 6 from rotating with swivel nut 5, thereby cause screw mandrel 6 can't realize the result of lifting, also prevented the contingent absent-mindedness of high-order support.
In this structure described locating slot or plane of orientation 8 axially are provided with longly, alignment pin 9 still can realize that in that it is not circumferentially hindered moving axially of screw mandrel 6 during the location yet screw mandrel 6 moves up and down normally under the rotation of turning handle 4 like this; Letter, alignment pin 9 mainly is the circumferential location of screw mandrel 6, does not hinder screw mandrel 6 axial moving.
