Abstract
The utility model discloses a kind of resilient pin of packing box, including winding the cylindrical body formed by elastic sheet, it is provided with to adjust body diameter size on body and the overlay segment formed that overlapped by elastic sheet.A kind of resilient pin of packing box of the utility model design has many advantages, such as that compression zone is big, serious forgiveness is high, easy to assembly, processing is simple.
Description
Technical field
The utility model is related to a kind of bolt more particularly to a kind of resilient pins of packing box.
Background technology
In the prior art, packing boxes, the upper cover such as similar spectacle case are attached with lower box junction using resilient pin,
Resilient pin with reference to shown in figure 1, current is generally designed using opening, and opening both sides set sawtooth, and both sides close up in open circles
Tubular, sawtooth are mutually aligned the gap for preventing from misplacing and staying one fixed width, resilient pin are gently tapped and is fitted into packing box
In axis hole, because shaft hole diameter is slightly less than resilient pin outer diameter, resilient pin periphery is compressed by shaft hole inner wall, and gap becomes smaller, elasticity
Bolt can provide tensile force to axis hole accordingly makes box be fixed with the relative position covered；But existing resilient pin is lacked there is also following
It falls into：First, compressible amount is fixed and small, cause serious forgiveness low, can cause to compress very few when axis hole bolt bigger than normal is less than normal, elasticity is inserted
It sells tensile force and reduces even 0, box cover cannot keep after opening in open position, experience lf being influenced, and when the small bolt of axis hole is big, bullet
Property bolt gap is stayed to be compressed to its minimum outer diameter can not also meet matching requirements, assembling will cause bullet by force under percussion at this time
Property bolt damage；Second is that since resilient pin vertical opening does not form a complete cylinder type, both sides set sawtooth to add
Difficulty of processing, outer diameter uniformity be difficult to ensure that, when installation easily gets stuck, and influences efficiency of assembling.
The content of the invention
The utility model aims to solve the problem that the technical issues of above-mentioned mentioned, provides that a kind of compression zone is big, serious forgiveness is high, dress
With convenience, process simple resilient pin.
The utility model is realized by following technical solution：A kind of resilient pin of packing box, including by elasticity
The cylindrical body and the both sides of thin slice that winding of webs is formed overlap and are configured to adjust covering for body diameter size
Lid section.
Preferably, the overlay segment becomes smaller with body diameter and winds elongation, remains the cylinder-like structure of body.
Preferably, the covering segment length is less than the body diameter one circumference of circle.
Preferably, the overlay segment is equal with the width of body connecting portion, and overlay segment can be square with body both sides, point
Taper, arc-shaped, stairstepping.
Preferably, the cylindrical body wherein one or both ends are provided with chamfered section, guiding during convenient for assembling, and can
Fabrication hole or technique lines, positioning easy to process are set on body and overlay segment.
Preferably, the elastic sheet is metal.
Advantageous effect is：
Compared with prior art, a kind of resilient pin of packing box of the utility model has the following advantages：Pass through setting
Overlay segment increases the compressible scope of resilient pin outer diameter so that resilient pin adapts to various sizes of axis hole, serious forgiveness
It greatly improves；The resilient pin of the utility model is designed as complete cylindrical shape, avoids the shedding deformation of existing design, non-defective unit
Rate improves, and assembling is good；The resilient pin both sides of the utility model are without sawtooth, and processing is simpler, and shaping outer diameter uniformity is good.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, wherein：
Fig. 1 is prior art opening bolt front view；
Fig. 2 is a kind of graphics of the resilient pin of packing box of the utility model；
Fig. 3 is side schematic view when a kind of resilient pin of packing box of the utility model is uncompressed；
Side schematic view when Fig. 4 is a kind of resilient pin compression of packing box of the utility model；
Fig. 5 is that a kind of resilient pin both ends of packing box of the utility model set the schematic diagram of chamfering embodiment.
Specific embodiment
Refering to what is shown in Fig. 2, a kind of resilient pin of packing box, including winding the cylindrical body 2 formed by elastic sheet,
And the both sides of thin slice overlap and are constructed of overlay segment 1,1 length of overlay segment is less than one circumference of body and is close to body
On for adjusting 2 outer diameter of body.
With reference to shown in figure 3, Fig. 4, cylindrical body 2 along the circumferential direction has elasticity, and overlay segment 1 is by the body 2 in compression
Outer diameter becomes smaller, and overlay segment 1 is close to the winding elongation of body 2 so that body still keeps cylinder-like structure.
Refering to what is shown in Fig. 5, being provided with chamfered section 3 in 2 one or both ends of body, chamfered section diameter is with respect to interlude diameter
It is small, it play the guiding role when resilient pin is inserted into packing box axis hole, convenient for the assembling with packing box axis hole.
In processing, overlay segment is integrated resilient pin with body, and the two quite prevents song in the width of connecting portion
It sticks up, disjunct both ends can be square respectively, sharp cone distal, arc-shaped, stairstepping, be positioned convenient for Fixture Design and equipment；Simultaneously
Fabrication hole or technique lines on body and overlay segment can be set, facilitate locating and machining.
When resilient pin is with peg-in-hole assembly, with reference to shown in figure 3, Fig. 4, both ends are gently tapped, it is elastic under the effect of external force
In bolt insertion packing box axis hole, 2 outer diameter of body is compressed to D2 under the limitation of shaft hole inner wall by D1, and overlay segment 1 is therewith by cba
For segment elongation to cbad, body 2 is always cylindric with overlay segment 1；After being fitted into axis hole, resilient pin continues in compressive state
One corresponding tensile force is applied to shaft hole inner wall, under the action of this tensile force, axis hole once has generation is opposite to turn with bolt
Dynamic trend can all have enough stiction to hinder relative motion；Box cover is broken during use into two with one's hands manually to any part, hand unclamps
Back box cover can keep the position motionless by box cover under the action of stiction.
Above example is only to illustrate the technical solution of the utility model and is not limited, all without departing from this
Any modification of utility model spirit and scope or equivalent substitution should all cover the scope in technical solutions of the utility model
It is interior.
