Abstract
A fast locking pin comprises a locking body, a pull rod, a handle, a spring and a steel bead, wherein a pull bar is arranged inside the locking body; a rotary table is arranged on the lower part of the pull rod and is contacted with the steel bead in the circular hole of the locking body; a spring is sleeved on the middle and upper part of the pull bar; one end of the spring supports on the upperend face of the rotary table of the pull bar and the other end supports on the inner wall of the locking body; the upper end of the pull rod extends out of the locking body and is movably connected with the handle through a shaft lock; when the axis of the handle is coaxial with the axis of the locking body, the steel bead is withdrawn in the locking body; when the axis of the handle is mutually perpendicular to the axis of the locking body, the steel bead protrudes out of the external surface of the locking body under the action of the rotary table. The fast locking pin has the advantages offast locking, accurate positioning and convenient dismounting.
Description
Technical field
The utility model relates to a kind of quick spring bolt that can lock fast and unclamp.
Background technique
Traditional welding does not generally have unified spring bolt, and general welding structural element is exactly to look for a bigger iron plate of thicker area to do basic platform, all is to weld some auxiliary block when participating in the cintest to replace using nut check as locating or compress, and precision not high efficiency is low.This quick spring bolt cooperates platform and annex to use, characteristics such as quick, the accurate location of locking, convenient disassembly.
Summary of the invention
The technical problem that the utility model solves is: a kind of quick spring bolt that can lock fast and unclamp is provided.
Concrete technological scheme of the present utility model is: a kind of quick spring bolt is provided, comprise locking body, pull bar, handle, spring and steel ball, in described locking body, be provided with pull bar, the bottom of described pull bar is a Rotary-table, the described Rotary-table steel ball interior with being arranged on the locking body circular hole contacts, be with spring in described pull bar middle and upper part, spring one end withstands on the last end face of Rotary-table of described pull bar, and the other end withstands on the described locking body inwall; Described pull bar upper end stretches out in outside the locking body, and by shaft lock and the flexible connection of described handle, and order is when the axis of handle is in axis coaxle with described locking body, described steel ball closes in the locking body, when the axis of handle is in axis with locking body when vertical mutually, described steel ball protrudes from the outer surface of described locking body under the effect of Rotary-table.
Upper end at described locking body is provided with nut, and described nut is connected with described locking body screw.
Described locking body is cylindrical.
The utility model in use, earlier locking body of the present utility model is inserted in the hole of locked object, be screwed into low spot with under the handle then, handle drive this moment pull bar up moves, the Rotary-table of pull bar bottom is extruded a part with many steel balls outside locking body, and make the diameter of the diameter on plane, steel ball place greater than locking body, and the utility model can not directly be extracted out from the hole; But when needs take out the utility model, can the axis of handle and the axis of described locking body be on the line up turn of pull bar, at this moment, pull bar is rebounded under the elastic force effect of spring, and steel ball may be withdrawn in the locking body, just can extract locking body smoothly out.Therefore, spring bolt has the advantage of quick, the accurate location of locking, convenient disassembly fast, and on-the-spot use of convenient working personnel operated.

Embodiment
See also Fig. 1 to Fig. 3, what the utility model disclosed is a kind of quick spring bolt, comprise cylindrical locking body 1, pull bar 2, handle 3, spring 4 and steel ball 5, in described locking body 1, be provided with pull bar 2, the bottom of described pull bar 2 is Rotary-tables 21, and the steel ball 5 in described Rotary-table 21 and the circular hole that is arranged on locking body 1 contacts, and is with spring 4 in described pull bar 2 middle and upper parts, spring 4 one ends withstand on the last end face of Rotary-table 21 of described pull bar 2, and the other end withstands on described locking body 1 inwall; Described pull bar 2 upper ends stretch out in outside the locking body 1, and by shaft lock 6 and described handle 3 flexible connections, when the axis of handle 3 is in axis coaxle with described locking body 1 (when the axis of the axis of handle 3 and locking body 1 is straight line), described steel ball 5 closes in the locking body 1, when the axis of handle 3 is in axis with locking body 1 when vertical mutually, described steel ball 5 protrudes from the outer surface of described locking body 1 under the effect of Rotary-table 21.Be provided with nut 7 in the upper end of described locking body 1, described nut 7 is connected with described locking body 1 screw.
The utility model in use, when needs locking object, quick spring bolt can be inserted in the gauge hole on the annex that needs locking, move handle (as shown in Figure 2 to minimum point, locking state), 5 steel balls 5 in the locking body 1 eject into locking state, then with will be locked body locking of spanner adjusting lock nut 7.When needs unclamp the object that is locked, the handle of quick spring bolt can be moved extreme higher position (as shown in Figure 1, releasing orientation), 5 steel balls in the locking body 1 rebound in the locking body, and releasing orientation is locked in locking fast, can take out quick spring bolt.
Fig. 3 is the perspective view of Fig. 1.
Claims (3)
1, a kind of quick spring bolt, it is characterized in that: comprise locking body, pull bar, handle, spring and steel ball, in described locking body, be provided with pull bar, the bottom of described pull bar is a Rotary-table, the described Rotary-table steel ball interior with being arranged on the locking body circular hole contacts, be with spring in described pull bar middle and upper part, spring one end withstands on the last end face of Rotary-table of described pull bar, and the other end withstands on the described locking body inwall; Described pull bar upper end stretches out in outside the locking body, and by shaft lock and the flexible connection of described handle, and order is when the axis of handle is in axis coaxle with described locking body, described steel ball closes in the locking body, when the axis of handle is in axis with locking body when vertical mutually, described steel ball protrudes from the outer surface of described locking body under the effect of Rotary-table.
