Abstract
The invention relates to a chuck for overload protection. The chuck for overload protection is used for connecting an upper plate and a lower plate. The chuck is axisymmetric. The chuck comprises a head portion, waist portions and tail portions. Elastic protrusions are arranged on the two sides of the head portion. The waist portions are connected with the two tail ends of the head portion. The tail portions are connected with the waist portions. The tail portions are perpendicular to the axis. The tail portions are clamped in the lower plate. The head portion is clamped in the upper plate. Compared with the prior art, the chuck for overload protection is simple in structure, convenient to install and capable of achieving an overload protection effect.
Description
Technical field
The present invention relates to plate mounting technology field, be specifically related to a kind of chuck for overload protection.
Background technology
Assembling between the material such as metalwork, working of plastics, generally adopts chuck to realize. The chuck of prior artFor link assembling, existing chuck has fixed assembly relation completely, is prone to plate distortion, cracking in assembling process,There is the shortcoming of dismounting trouble, fragile, poor durability, and chuck can not play overload protective function, cannotMeet the quality requirement day by day promoting.
Summary of the invention
Object of the present invention is exactly to provide a kind of simple in structure, tool in order to overcome the defect that above-mentioned prior art existsThere are overload protection characteristics, the chuck for overload protection that cost is low.
Object of the present invention can be achieved through the following technical solutions:
For a chuck for overload protection, for being connected of upper plate and lower plate, described chuck is about axis symmetry,This chuck comprises head, waist and afterbody, and described head both sides are elastic bumps, described waist and headTwo ends connect, described afterbody is connected with waist, and afterbody is vertical with axis, described trailer card is located atIn lower plate, described head is fastened in upper plate.
Described head comprises two sidewalls, and two described sidewall one end are connected to form the upper end of head, sidewallThe press section of two outwardly convexs is formed at bottom.
When described press section is squeezed power, press section is inwardly compressed, and the distance between two press sections reduces. ?Head is in the time assembling or dismantle, and when the suffered power in press section slowly becomes greatly, two sidewalls of head will be inwardsDraw close, in the time that power radially reaches a certain particular value, head just can insert or come off, this machine in the draw-in groove of upper plateReason 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 sectionBetween distance, be the structure of " head large waist thin ".
Described chuck processes by mould punching.
Described upper plate arranges upper plate hole slot, in the time that upper plate is not connected with chuck, and the diameter of described upper plate hole slot notchBe less than the distance between described two press sections.
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 comprise bottom translot andVertically notch, in the time that chuck is installed on lower plate, described trailer card is located in the bottom translot of lower plate draw-in groove, described inWaist be fastened in vertical notch.
When chuck assembling of the present invention, afterbody is first mounted in lower plate, after fixing, then assemble with upper plate,When upper plate assembling, head is aimed to upper plate hole slot and compress into, along with the change of pressure is large, head both sides width can be graduallyDiminish, when pressure reaches after a certain particular value, head narrows down to and can just stick in upper plate hole slot, continue downwards,The effect of head two side force reduces, and it is slightly wide that head both sides become, and clamping upper plate, fits tightly upper plate and lower plateTogether, just completed assembling. When dismounting, when pulling force is greater than after a certain particular value, head both sides width is reduced toUpper plate hole slot is size equally, and upper plate will separate from chuck, thereby realizes the overload protection of upper and lower plates.
Compared with prior art, beneficial effect of the present invention is embodied in following several respects:
(1) the art of this patent be skillfully constructed, modern design, can realize overload protection function, and only need be by chuckBe installed and can complete installation into installing plate.
(2) the art of this patent is also good project for the investor, drops into not highly, and the large market of small item, investsReturn rate is quite high.
(3) safe and reliable: but pulling force is when excessive, and chuck returns realizes Automatic-falling.
(4) increase work efficiency: original chuck can only play the effect of being linked and packed, and cannot realize overload protection. And thisThe installing hole that patent only need snap in chuck installing plate can complete installation, and reaches after a certain particular value at pulling force,Can also play overload protection function.
(5) reduce costs: this chuck structure is simple, and bulk strength is high, die cost and process-cycle thanOriginal chuck all shortens greatly.
Brief description of the drawings
Fig. 1 is the structural representation of chuck of the present invention;
Fig. 2 is the assembling schematic diagram of chuck of the present invention.
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
Below embodiments of the invention are elaborated, the present embodiment enters under taking technical solution of the present invention as prerequisiteRow is implemented, and provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to downThe embodiment stating.
Embodiment 1
For a chuck for overload protection, as shown in Figure 1, this chuck 1 comprises compressible head to its structure successivelyPortion 11, waist 12 and afterbody 13, head 11 comprises two sidewalls, one end of two sidewalls is connected to form head11 upper end, the press section of two outwardly convexs is formed at the bottom of sidewall, and head 11, in the time being squeezed, is pressedDistance between portion can be dwindled, in the time that the power of extruding is dwindled, and head 11 resilients. Afterbody 13 and chuck 1Axis vertical, waist 12 connects head 11 and afterbody 13, head 11 is " the large waist of head is thin " with waist 12Structure.
When this chuck 1 is for connecting two boards material, its assembly structure as shown in Figure 2. Upper plate 2 is offered hole slot, underPlate 3 is offered inverted T shape draw-in groove, and this inverted T shape draw-in groove comprises bottom translot and vertical notch, when chuck 1 is installed onWhen lower plate 3, afterbody 13 is fastened in the bottom translot of lower plate 3 draw-in grooves, and waist 12 is fastened in vertical notch.After fixing, then assemble with upper plate 2, when upper plate 2 assembles, head 11 is aimed to the hole slot of upper plate 2Compress into, along with the change of pressure is large, head 11 both sides width can diminish gradually, when pressure reaches a certain particular valueAfter, 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 headReduce, head 11 both sides become slightly wide, and clamping upper plate 2 makes together with upper plate 2 fits tightly with lower plate 3,Just complete assembling. When dismounting, when pulling force is greater than after a certain particular value, head 11 both sides width are reduced to upper plate2 hole slot is size equally, and upper plate 2 will separate from chuck 1, thereby realizes the overload protection of upper and lower plates.
