Abstract
The utility model relates to a chuck for overload protection for upper plate and lower joining of plates, the chuck about axis symmetry, this chuck includes head, waist and afterbody, the head both sides be elastic bulge, two end -to -end connections of waist and head, the afterbody be connected with the waist, and the afterbody is perpendicular with the axis, the afterbody card establish inboard under, the head card establish at last inboard. Compared with the prior art, the utility model discloses simple structure, simple to operate can play overload protection's effect.
Description
Technical field
This utility model relates to plate mounting technology field, is specifically related to a kind of chuck for overload protection.
Background technology
Assembling between the material such as metalwork, working of plastics, general employing chuck realizes.The chuck of prior art
For link assembling, existing chuck has fixed assembly relation completely, easily occurs plate deformation, cracking during assembling,
There is dismounting trouble, fragile, the shortcoming of poor durability, and chuck can not play overload protective function, it is impossible to
Meet the prescription day by day promoted.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of structure letter is provided
Singly, there is the chuck for overload protection of overload protection characteristics, low cost.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of chuck for overload protection, for the connection of upper plate Yu lower plate, described chuck is symmetric about the axis,
This chuck includes that head, waist and afterbody, described head both sides are elastic bumps, described waist and head
Two ends connect, described afterbody is connected with waist, and afterbody is vertical with axis, and described trailer card is located at
In lower plate, described head is fastened in upper plate.
Described head includes that two sidewalls, two described sidewall one end connect the upper end forming head, sidewall
The press section of two outwardly convexs is formed at bottom.
Described press section be squeezed power time, press section inward compression, distance between two press sections reduces.I.e.
Head is when carrying out assembly or disassembly, and when the power suffered by press section slowly becomes big, two sidewalls of head will be inwards
Drawing close, when power radially reaches a certain particular value, head will be inserted into from the draw-in groove of upper plate or come off, this machine
Reason can also play overload protective function.
The two ends of described waist are connected with afterbody with described head respectively, and the distance between waist is less than press section
Between distance, in the structure of " the big waist of head is thin ".
Described chuck is processed by mould punching.
Described upper plate arranges upper plate hole slot, when upper plate is not connected with chuck, and the diameter of described upper plate hole slot notch
Less than the distance between said two press section.
Described lower plate arranges lower plate draw-in groove, and this lower plate draw-in groove is inverted T shape, lower plate draw-in groove include bottom translot and
Vertically notch, when chuck is installed on lower plate, described trailer card is located in the bottom translot of lower plate draw-in groove, described
Waist be fastened in vertical notch.
During the assembling of this utility model chuck, afterbody is first mounted in lower plate, to be fixed good after, then fill with upper plate
Join, during upper plate assembling, head alignment upper plate hole slot is pressed into, along with the change of pressure is big, the width meeting of head both sides
Tapering into, after pressure reaches a certain particular value, head narrows down to and can just stick in upper plate hole slot, continue to
Under, the effect of head two side force reduces, and head both sides become the widest, clamping upper plate so that upper plate is tight with lower plate
Fit together, just complete assembling.During dismounting, after pulling force is more than a certain particular value, head both sides width subtracts
Little to the same size of upper plate hole slot, upper plate will separate from chuck, thus realize the overload protection of upper and lower plates.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) the art of this patent be skillfully constructed, novel in design, overload protection function can be realized, and only need to be by chuck
It is installed and can complete to install into installing plate.
(2) the art of this patent is also good project for the investor, puts into the highest, the big market of small item, investment
Return rate is at a relatively high.
(3) safe and reliable: but when pulling force is excessive, chuck returns and realizes Automatic-falling.
(4) work efficiency is increased: original chuck can only play the effect of being linked and packed, it is impossible to realizes overload protection.And this
Chuck only need to be snapped in the installing hole of installing plate and can complete to install by patent, and after pulling force reaches a certain particular value,
Overload protection function can also be played.
(5) reducing cost: this chuck structure is simple, bulk strength is high, die cost and process-cycle compared to
Original chuck is all greatly shortened.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model chuck；
Fig. 2 is the assembling schematic diagram of this utility model chuck.
Wherein, 1 is chuck, and 11 is head, and 12 is waist, and 13 is afterbody, and 2 is upper plate, and 3 is lower plate.
Detailed description of the invention
Elaborating embodiment of the present utility model below, the present embodiment with technical solutions of the utility model is being
Implement under premise, give detailed embodiment and concrete operating process, but protection of the present utility model
Scope is not limited to following embodiment.
Embodiment 1
A kind of chuck for overload protection, its structure is as it is shown in figure 1, this chuck 1 includes compressible head successively
Portion 11, waist 12 and afterbody 13, head 11 includes two sidewalls, and one end of two sidewalls connects formation head
The upper end of 11, the press section of two outwardly convexs is formed at the bottom of sidewall, and head 11, when being squeezed, presses
Distance between portion can reduce, when the power of extruding reduces, and head 11 resilient.Afterbody 13 and chuck 1
Axis vertical, waist 12 connects head 11 and afterbody 13, and head 11 and waist 12 are in " the big waist of head is thin "
Structure.
When this chuck 1 is used for connecting two boards material, its assembling structure is as shown in Figure 2.Upper plate 2 offers hole slot, under
Inverted T shape draw-in groove offered by plate 3, and this inverted T shape draw-in groove includes bottom translot and vertical notch, when chuck 1 is installed on
During lower plate 3, afterbody 13 is fastened in the bottom translot of lower plate 3 draw-in groove, and waist 12 is fastened in vertical notch.
To be fixed good after, then assemble with upper plate 2, when upper plate 2 assembles, head 11 be directed at the hole slot of upper plate 2
Being pressed into, along with the change of pressure is big, head 11 both sides width can taper into, when pressure reaches a certain particular value
After, head 11 narrows down in the hole slot that can just stick into upper plate 2, continues downwards, the effect of 11 liang of side force of head
Reducing, head 11 both sides become the widest, clamping upper plate 2 so that together with upper plate 2 fits tightly with lower plate 3,
Just complete assembling.During dismounting, after pulling force is more than a certain particular value, head 11 both sides width is reduced to upper plate
The same size of hole slot of 2, upper plate 2 will separate from chuck 1, thus realize the overload protection of upper and lower plates.
