Description
Technical field
The utility model is related to drawing-aid devices used in a kind of communications industry high density board.
Background technology
The fiber interface end of the high density board of light communication as is illustrated in the left side of fig. 1, due to ray density height, occupies
The area of entire side, in this way after current drawing-aid device locking, handle will part overlaid optical fiber crystal head interface, lead
Cause optical fiber crystal head that can not be inserted into, the method for routinely solving the problems, such as this is the size of increasing cabinet, but this configuration reduces
The density of pcb board plug-in unit, it is less economical.
Utility model content
Pcb board package density, this practicality are not influenced in order to solve the interference between drawing-aid device and optical fiber crystal head simultaneously
A kind of novel drawing-aid device of offer.The technical solution of the utility model is：By drawing-aid device shaft seat, drawing-aid device handle, drawing-aid device seat,
Movable rotation-shaft, fixed rotating shaft, rotation base shaft, spring composition；On the drawing-aid device shaft seat setting there are one rotary stopper slot,
One shaft seat limiting slot；There are one handle positioning bar, a sliding spacer pin and spring installations on the drawing-aid device handle
Column；There are one waist-shaped hole and spring mounting holes in the rotation base shaft；The drawing-aid device taper knob is in the rotation base
And it can sliding axially along rotation base shaft on bar；One end of the spring is mounted on spring mounting hole, other end installation
In spring mounting post；The sliding spacer pin is placed in waist-shaped hole to limit the drawing-aid device handle along rotation base shaft
Sliding stroke；The handle positioning bar can be inserted into the rotary stopper slot and shaft seat limiting slot.
The utility model is using the advantageous effect of above technical scheme：Using the drawing-aid device that can turn to folding, avoid
Interference between drawing-aid device and optical fiber crystal head improves pcb board package density.
Description of the drawings
Fig. 1, be drawing-aid device application schematic diagram；
Fig. 2,3,4,5 are the structural schematic diagrams of the utility model.
In figure, 1 drawing-aid device shaft seat, 2 drawing-aid device handles, 3 drawing-aid device seats, 4 movable rotation-shafts, 5 fixed rotating shafts, 6 rotation bases
Bar, 7 springs, 111 rotary stopper slots, 112 shaft seat limiting slots, 211 handle positioning bars, 212 sliding spacer pins, 213 springs peace
Fill column, 611 waist-shaped holes, 612 spring mounting holes.
Specific implementation mode
As shown in Figure 2,4, the utility model is by drawing-aid device shaft seat 1, drawing-aid device handle 2, drawing-aid device seat 3, movable rotation-shaft
4, fixed rotating shaft 5, rotation base shaft 6, spring 7 form；As shown in figure 3, there are one rotations for setting on the drawing-aid device shaft seat 1
111, shaft seat limiting slots 112 of limiting slot；There are one the 211, slidings of handle positioning bar on the drawing-aid device handle 2
Spacer pin 212 and spring mounting post 213；As shown in figure 4, there are one waist-shaped holes 611 and spring to install in the rotation base shaft 6
Hole 612；The drawing-aid device handle 2 is sleeved in the rotation base shaft 6 and can sliding axially along rotation base shaft 6；It is described
Spring 7 one end be mounted on spring mounting hole 612 on, the other end be mounted on spring mounting post 213 on；The sliding limit
Pin 212 is placed in the sliding stroke to limit the drawing-aid device handle 2 along rotation base shaft 6 in waist-shaped hole 611；The handle
Positioning bar 211 can be inserted into the rotary stopper slot 111 and shaft seat limiting slot 112.
The operation principle of the utility model is：The original state of drawing-aid device handle 2 as shown in Fig. 2, drawing-aid device handle 2 with help
It pulls out device seat 3 and keeps vertical in the case where handle positioning bar 211 is inserted into rotary stopper slot 111, high density board can be real at this time
Existing intelligent acess extracts operation.When high density board needs to safeguard or replace, first drawn optical fiber, then by drawing-aid device handle
2 extract outward with respect to rotation base shaft 6 so that handle positioning bar 211 disengages rotary stopper slot 111, then rotates drawing-aid device hand
Handle 2 is simultaneously pulled and is pressed onto state as shown in Figure 5, drawing-aid device handle 2 is rotated at this time under the action of spring 7 relative to rotation base shaft 6
It automatically resets and handle positioning bar 211 is inserted into holding handle folded state in shaft seat limiting slot 112；Finally extract board.
The above specific embodiments are only exemplary, is to preferably make skilled artisans appreciate that originally
Patent, be not to be construed as include to this patent range limitation；As long as being made according to technical solution disclosed in this patent
The substantially identical or equivalent any change or modification of technology contents, each fall within the range that this patent includes.
