Abstract
The utility model relates to a kind of Special rotary spanner for the assembling of microtubule special joint, belongs to communications optical cable equipment technical field.Special rotary spanner is made up of pullover, set lever and bearing pin, and pullover is U-shaped, and the pullover bottom of U-shaped has trepanning, and the pullover top of U-shaped forms draw-in groove, and the both sides of draw-in groove have the first pin shaft hole.One end of set lever has finger hole, and the other end has the second pin bore axis, and the edge of the other end of set lever is arc, forms locking arc.The arc tips of set lever stretches in pullover draw-in groove, and bearing pin inserts in the second pin bore axis of set lever and the first pin shaft hole of draw-in groove both sides.This Special rotary spanner, utilizes the locking circular arc of set lever and the bias of bearing pin to be locked by workpiece, then continues to rotate, and is screwed by workpiece.Be suitable for rotary distance longer, threaded engagement is comparatively tight, the work that work batch is larger, and workman can be made to work laborsaving, operating efficiency improves greatly.
Description
Technical field
The utility model relates to a kind of Special rotary spanner for the assembling of microtubule special joint, belongs to communications optical cable equipment technical field.
Background technology
The applicant in order to correctly, carry out the construction of communications optical cable fast, propose a kind of special joint of the microtubule that communicates, its structure as shown in Figure 1, in use, because locknut and core pipe adopt screw thread self-locking tight, internal and external threads has certain interference to this special joint, therefore in an assembling process, labor strength is large, under efficiency, but the instrument that market is not applicable to again.
Summary of the invention
The purpose of this utility model proposes a kind of Special rotary spanner for the assembling of microtubule special joint, to reduce labor strength, increases work efficiency, reduce entreprise cost.
The Special rotary spanner for the assembling of microtubule special joint that the utility model proposes, be made up of pullover, set lever and bearing pin, described pullover be U-shaped, the pullover bottom of U-shaped has trepanning, the top formation draw-in groove that U-shaped is pullover, the both sides of draw-in groove have the first pin shaft hole; One end of described set lever has finger hole, and the other end of set lever has the second pin bore axis, and the edge of the other end of set lever is arc, forms locking arc; The arc tips of described set lever stretches in described pullover draw-in groove, and described bearing pin inserts in the second pin bore axis of set lever and the first pin shaft hole of draw-in groove both sides.
A kind of Special rotary spanner for the assembling of microtubule special joint that the utility model proposes, utilizes the locking circular arc of set lever and the bias of bearing pin to be locked by workpiece, then continues to rotate, is screwed by workpiece.Be suitable for rotary distance longer, threaded engagement is comparatively tight, the work that work batch is larger, and workman can be made to work laborsaving, operating efficiency improves greatly.

In Fig. 2-Fig. 4,1 is pullover, and 1-1 is draw-in groove, and 1-2 is the first pin shaft hole, and 1-3 is trepanning, and 2 is set levers, and 2-1 is locking arc, and 2-2 is finger hole, and 2-3 is the second pin shaft hole, and 3 is bearing pins.
Detailed description of the invention
The Special rotary spanner for the assembling of microtubule special joint that the utility model proposes, its structure as shown in Figure 2, is made up of pullover 1, set lever 2 and bearing pin 3.The structure of pullover 1 as shown in Figure 3, is U-shaped, and the pullover bottom of U-shaped has trepanning 1-3, and the pullover top of U-shaped forms draw-in groove 1-1, and the both sides of draw-in groove have the first pin shaft hole 1-2.As shown in Figure 4, its one end has finger hole 2-2 to the structure of set lever 2, and the other end of set lever has the second pin bore axis 2-3, and the edge of the other end of set lever 2 is arc, forms locking arc 2-1.The arc tips of set lever stretches in the draw-in groove of described pullover 1, and bearing pin inserts in the second pin bore axis of set lever and the second pin shaft hole of draw-in groove both sides.
The Special rotary spanner for the assembling of microtubule special joint that the utility model proposes, its use procedure is: set lever 2 inserts in the draw-in groove 1-1 of pullover 1, the first pin shaft hole 1-2 is alignd with the 2nd 2-3, then bearing pin 3 is inserted pin shaft hole.During work, the threaded special joint part of the endoporus that will assemble is inserted in trepanning 1-3, finger is put into finger hole 2-2 to rotate, make pullover 1 and set lever 2 around bearing pin 3 relative movement, locking arc 2-1 and the second pin shaft hole 2-3 is eccentric, thus along with rotation lock arc 2-1 can incision trepanning 1-3 gradually, joint part is locked, be rotated further, just the tapped collar nut rotation set in communication microtubule special joint be as shown in Figure 1 with on externally threaded joint part.
The Special rotary spanner for the assembling of microtubule special joint that the utility model proposes, is suitable for rotary distance longer, and threaded engagement is comparatively tight, the work that work batch is larger, and workman can be made to work laborsaving, operating efficiency improves greatly.
