Abstract
This utility model provides a kind of fastener, and including the first jig arm and the second jig arm, the first described jig arm and the root of the second jig arm are fixedly connected to form on straight line by a junction respectively, and the first described jig arm and the end of the second jig arm inwardly encircle structure；Being provided with the cam utilizing connecting shaft fixing on described connecting portion, described cam realized being pressed down against to the first jig arm and the second jig arm place straight line and loosening when connecting shaft rotates.As such, it is possible to clamp lamellar or tabular clamping thing in the structure that the first jig arm and the second jig arm are inwardly encircled, utilize cam and loosen the clamping thing clamping making lamellar or loosen.
Description
Technical field
This utility model relates to connector field, two panels or more sheets is buckled together particularly to one
Fastener.
Background technology
Fastener, as a kind of clamp device, is widely used in various field and fastens, such as building field with
Build scaffold.In the prior art, fastener generally comprises cover plate and pedestal, is formed by bearing pin between cover plate and pedestal
It is rotatably connected.This fastener uses very frequent at building field, is usually used to build scaffold, and use is convenient to,
As China Patent Publication No. CN 105298109 A discloses such a fastener, this fastener includes the first jig arm and the second folder
Arm, the first end of the first jig arm and the first end of the second jig arm are rotatably connected each other by rotatable connection,
The cavity for accommodating this object when clamping object, wherein, this rotatable connection is formed between first and second jig arm
Including bearing pin and wind this bearing pin and around the rotatable winder of this bearing pin, this winder is with its first end and first and
One of two jig arm connect or as one part, and this bearing pin is connected or conduct with another in described first and second jig arm
One part, and the second end of this winder is positioned in described cavity and rubs with this object when this fastener clamping object
Contact.In use, clamping thing is the steel pipe that some cylinders use when such as building scaffold to this fastener, but can not use
In clamping tablet if desired for two block plates connected, being even clamped together by two boards material when mounted lamp, it is solid to play
Determine the effect of two boards material.
Utility model content
This utility model can not clamp sheet material not to overcome current fastener to be suitable for clamping the tubing such as steel pipe
Foot, it is provided that a kind of for clamping two pieces or the fastener of more parallel sheet material.
The technical solution of the utility model is a kind of fastener, including the first jig arm and the second jig arm, the first described jig arm
It is fixedly connected to form straight line, the first described jig arm and the second jig arm by a junction respectively with the root of the second jig arm
End inwardly encircles；Being provided with the cam utilizing connecting shaft fixing on described connecting portion, described cam revolves around connecting shaft
Realize when turning being pressed down against to the first jig arm and the second jig arm place straight line and loosening.
As such, it is possible to clamp lamellar or tabular clamping thing in the structure that the first jig arm and the second jig arm are inwardly encircled,
Utilize cam and loosen the clamping thing clamping making lamellar or loosen.
Further, in above-mentioned fastener: be additionally provided with the cam described in drive on described cam and revolve around connecting shaft
The handle turned.The side of the described handle radius the shortest with cam is vertical.
Handle is so utilized can preferably to operate fastener, when handle and the shortest radius are that vertical side is near first
During the straight line at jig arm and the second jig arm place, cam no longer extrudes clamping thing, when the opposite side of handle is near the first jig arm and
During the straight line at two jig arm places, cam extends downwardly from the deepest.
Below in conjunction with specific embodiment, this utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model embodiment 1 fastener.
Fig. 2 is the top view of this utility model embodiment 1 fastener.
Fig. 3 is that this utility model embodiment 1 fastener cam is connected figure with handle.
Detailed description of the invention
Embodiment 1, as depicted in figs. 1 and 2, the present embodiment is a kind of fastener used when mounted lamp, can be by
Together, the gross thickness of the two boards material being fixed up is less than 10mm to two boards material clip, can fill in two after gathering into folds
Between jig arm, then make two boards material compress by rotating cam, the radius of current cam from minimum 3mm to maximum 5mm, this
Sample, two boards material, along advancing 2mm, owing to there being tiller effect, can be buckled by cam wheel.
As depicted in figs. 1 and 2, the fastener of the present embodiment has the first jig arm 1 and the second jig arm 2, and two jig arm ends are each
Hooking in arranging one, so, if there being the sheet material of two pieces or more than two pieces to need to buckle, can pass in two jig arm.
The root of the first jig arm 1 and the second jig arm 2 is connected by a connecting portion 3 is fixing, by this connecting portion 3 first jig arm 1 and the
Two jig arm 1 two arms are in a straight line, and the interior hook of two ends does internally encircles shape, on connecting portion 3, arrange two pieces
Buttress, arranges a pavilion axle 5 on knee wall, installs cam 4 in rotating shaft 5, and cam 4 is around the shaft 5 when rotating, it is achieved with the
The straight line that one jig arm 1 and 1 two arms of the second jig arm are in flushes and extrudes on this straight line, and cam 4 rotates and driven by handle 6,
A handle 6 inherently lever, as it is shown on figure 3, cam 4 is one progressive to take turns, its radius progressively increases, the present embodiment
In for the fastener of light fixture, the radius of employing can be 3mm to 5mm, handle 6 vertical with the shortest radius, cam 4
Radius from 3mm to 5mm, so, when handle 6 is in time forwarding another side to, has been pressed downward against 2mm in semi-circumference.
