Utility model content
In order to overcome the shortcomings in the prior art, after the utility model provides a kind of installation, plate will not surround connecting rod
Rotate the double-end joint lever to skid.
A kind of double-end joint lever is connected between two plates by the mounting hole on plate, has bar core, and bar core both ends are equal
Equipped with head, the head and bar core are integrated, and the bar core is equipped with elastic fixing sleeve, the elastic fixing sleeve and bar core
It is fixed together so that connecting rod both ends form two necks, the flexible fastening is put on equipped with positioning protrusion, the positioning
Protrusion can prevent double-end joint lever from rotating and sliding in mounting hole.
Specifically, the positioning protrusion include be parallel to axial facade structures and be parallel to radial facade structures, and
Pyramid is formed, the pyramid tip is located at bar core neutrality line to head direction, pyramid plane perpendicular elastic fixing sleeve
On.
Specifically, the pyramid is arranged around elastic fixing sleeve interval, and the pyramid tip is respectively directed to two heads.
Specifically, the elastic fixing sleeve is laemodipodiform.
Specifically, the flexible fastening puts on convex stupefied along being axially arranged with.
Specifically, the positioning protrusion be set to it is convex it is stupefied on.
Specifically, the flexible fastening is put on equipped with hollow out, hollow out quilt when elastic fixing sleeve both ends are squeezed
It flattens, and hollow out surrounding plastic is in swelling state.
Specifically, the hollow out is cross, and cross is axially disposed vertically.
Specifically, the elastic fixing sleeve end is equipped with perpendicular to axial notch, and the notch is in elastic fixing sleeve two
Narrow when end is squeezed.
The beneficial effects of the utility model are: double-end joint lever, can be applied to the connection between both side plate, it is inclined using both sides
The locking of heart wheel tenses both sides side plate secured.Conventional double threaded screw is compared, it is fixed that utility model double-end joint lever adds center
Position convex design makes connecting rod make both sides pulling force consistent when no longer eccentric wheel is locked in shaking and both sides during installation, not will cause
The phenomenon that loosening on one side the tight while and encapsulated inflated design of elastic fixing sleeve squeezes eccentric wheel when locking eccentric wheel
It is encapsulated that it is allowed to expand, the secured of connecting rod and side plate is improved, is not easy to loosen.
Detailed description of the invention
Fig. 1 is the utility model structure diagram.
Fig. 2 is the utility model usage state diagram.
Fig. 3 is the utility model partial enlarged view.
Specific embodiment
The utility model is described in further detail now in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of double-end joint lever 1, has bar core 103 and two heads 101, head 101 and bar core 103 are
One, bar core 103 are equipped with elastic fixing sleeve 102, and elastic fixing sleeve 102 is fixed together with bar core 103 so that double end is connect
Bar 1 forms a neck 106, and the other end is symmetrical.Elastic fixing sleeve 102 is equipped with positioning protrusion, and positioning protrusion includes that can prevent
The parallel axial facade structures 151 that double-end joint lever 1 rotates in mounting hole can be inserted mounting hole edge when installing and open
The gap of slot, double-end joint lever 1 is fixed.It further includes prevent double-end joint lever 1 from sliding in mounting hole parallel radial
Facade structures 161, which can need the plate mounting hole unslotted relative position connected to offset with another piece, to reach double
Head connecting rod 1 will not be slided in mounting hole along axially bored line, with reference to Fig. 2 and Fig. 3, not mark slotting position in Fig. 3, it is possible to understand that
It is the slot for being bonded positioning protrusion shape for it.Positioning protrusion in embodiment is used along axial facade structures and radially facade
Structure forms pyramid 111,112, and 111,112 tip of pyramid is respectively to two head directions, 111,112 plane perpendicular of pyramid
Elastic fixing sleeve 102, and be located on 103 neutrality line of bar core.Pyramid 111,112 is arranged around the interval of elastic fixing sleeve 102, with
Just it offsets respectively with two boards joint face, 111,112 tip of pyramid is respectively directed to two heads 101, convenient when to install to insert
Enter to reserve in fluting.
On the other hand, elastic fixing sleeve 102 is to be designed using laemodipodiform, three sections of the present embodiment point, but specific merogenesis number is not
Implementation result is influenced, in Fig. 1, positioning protrusion is fixed on convex stupefied 105 along being axially arranged with convex stupefied 105 by an intermediate section, convex stupefied
105 design so that set middle part is more solid firm, such design it is same it is solid in the case where, more saving material.
Elastic fixing sleeve 102 is equipped with hollow out 108, and hollow out 108 is crushed when elastic fixing sleeve both ends are squeezed, and
108 surrounding elastomeric material of hollow out is in swelling state.It is preferred that hollow out 108 be it is cross, cross is axially disposed vertically, has in this way
Bigger elastic space.102 end of elastic fixing sleeve is equipped with perpendicular to axial notch 107, and notch 107 is in elastic fixing sleeve two
Narrow when end is squeezed, is similarly installation and provides more elastic spaces.
When the utility model is installed, please side plate 3 is drilled according to size, double-end joint lever 1 is inserted into side plate 3,
When positioning protrusion is caught in such as fluting in Fig. 2, stop；Side plate 3 is packed into dedicated eccentric wheel 2, and rotates clockwise locking.It is suitable
Hour hands rotating eccentricity wheel >=225 ° are locking state.Eccentric wheel has squeezed double-end joint lever 1 at this time, elastic fixing sleeve is wrapped
Glue makes its expansion, and double-end joint lever 1 is firmly installed with side plate 3.Another eccentric wheel is packed into other one block of side plate, then by two sides
Plate merges installation, locks eccentric wheel, and both side plate link at this time is completed.
The utility model is not limited to above-mentioned specific embodiment, and persons skilled in the art are according to the utility model public affairs
The content opened can be implemented the utility model or all using the utility model using other a variety of specific embodiments
Design structure and thinking, do simple change or change, both fall within the protection scope of the utility model.
