Description

The anchor clamps that are used for the soft barred body of clamping

Technical field

The utility model relates to a kind of anchor clamps, relates to a kind of anchor clamps that are used for the soft barred body of clamping particularly.

Background technology

Filter stick is an ingredient of Cigarette, plays part and filter the objectionable impurities in the flue gas or the effect of other particle when people suck cigarette.

When cigarette the time is accidentally impacted in transportation or carrying, and striking face is by chance when cigarette has that end face of pipe tobacco, and the quality problems of drop-head just might take place filter tip.Trace it to its cause, mainly contain following 2 points: 1) in the filter stick manufacture process, filter stick center glue does not apply or center glue applies the interrupted shape of inhomogeneous one-tenth; 2) it is narrower or applied amount is less that center glue applies width, causes the cohesive strength between filter core and forming paper not enough.Therefore, need that the cigarette before dispatching from the factory is carried out filter stick and detect, whether reach qualified index with the cohesive strength of check filter stick in cigarette.

Filter stick drop-head detector is exactly the instrument that detects above-mentioned filter stick bonding strength.It detects principle substantially: filter stick is cut into 〉=10.0mm or≤30.0mm long (or cigarette is propped up filter tip partly cut down), and clamp, use the thimble roof pressure filter stick end face certain hour of certain load then, whether be ejected with filter core as criterion.Wherein, the clamping of filter stick is finished by unit clamp.

The utility model content

The technical problems to be solved in the utility model provides a kind of novel clamp, but clamping is similar to the soft barred body of cigarette.

The utility model is by the following technical solutions:

A kind of anchor clamps that are used for the soft barred body of clamping, comprise shell, establish groove on the shell, the tripod claw sets up separately in the groove and along groove and moves, establish movable disk in the shell, correspondingly on the rotating disk establish three wire casings, every wire casing comprises first, second end, described first, second end is different with distance between the rotating disk center of circle, comprises that also three web members that move in described wire casing are fixed under the claw.

Preferably, described wire casing is a helix groove.

Preferably, described web member comprises axostylus axostyle and bearing, and axostylus axostyle one end connects claw, other end connection bearing, and bearing is embedded in the wire casing.

Preferably, be provided with the projection that can lead relatively on the described groove sidewall, correspondingly, each recessing of claw both sides.

Further, described shell is fixed in base, establishes deep gouge on the base, comprises first cavity that holds rotating disk, and described first cavity is established breach; Establish driving lever on the rotating disk, driving lever is positioned at indentation, there.

Further, on shell, bidding chi on the breach of base deep gouge is established dismountable register pin on the scale.

Preferably, the front end face of described claw is an inner concave arc surface, establishes sponge leather on the described inner concave arc surface.

The utility model adopts the tripod claw structure.Wire casing on the rotating disk can be realized the flexible of tripod claw through particular design in the time of rotation, claw can clamp barred body thus.The utility model is simple in structure, easy to operate, and is respond well.

Fig. 2 is the explosive view of Fig. 1.

Fig. 3 is the vertical view of base, and base is connected with bearing among the figure.

Fig. 4-5 launches and the view of shrinking for claw.

Embodiment

See Fig. 1～2, anchor clamps comprise shell 1, the third-class identical shaped groove 11 that sets up separately on described shell 1 periphery, and described groove 11 has guide effect, and claw 3 is located at respectively in the groove 11, forms the tripod claw, slides along groove 11 and realizes stretching motion.The front end face of tripod claw is inner concave arc surface 32, and when claw 3 one when shrink at the center in the same way, inner concave arc surface 32 neat effects can clamp filter stick.The cross sectional shape of claw 3 should be adaptive mutually with the shape of groove 11, preferably, is provided with the projection 12 that can lead on groove 11 sidewalls relatively, correspondingly, and each recessing 31 of claw 3 both sides.Be that groove 11 is " H " shape, claw 3 cross sections also are " H " shape, see Fig. 2.Paste certain thickness sponge leather on the inner concave arc surface 32, can play anti-skidding during with clamping filter stick (filter tip) and the buffering effect, guarantee the minimum deformation of filter stick (filter tip), and can in claw 3, not skid off during its end face bearing certain pressure.Hole 14 is opened in shell 1 upper surface, and thimble is exerted pressure by 14 pairs of filter stick end faces of this through hole.

Shell 1 is fixed in base 7, sees Fig. 2, and at the bear 13 of groove 11, shell 1 is spirally connected by this hole 13 with base 7.Be provided with movable disk 5 at

shell

1 and 7 of bases, peripheral hardware driving lever 6 on rotating disk 5 side direction works rotating disk 5 effects of stirring.Dig deep gouge on the base 7, comprise first cavity 71 and second cavity 72 that hold rotating disk 5, first cavity 71 is an imperfect circle jaggy, barbed portion is in communication with the outside by second cavity 72, second cavity 72 also is the space that restriction driving lever 6 moves, driving lever 6 is stirred in second cavity 72, can drive rotating disk 5 and rotate around the center.Establish the identical helix groove of three strips (being the arc groove) on the rotating disk 5, be connected with claw 3 by web member 4.Web member 4 can relative motion in helix groove, and web member 4 comprises axostylus axostyle 41 and the bearing 42 that is sheathed on axostylus axostyle 41 1 ends, and bearing 42 is embedded in the arc groove, and axostylus axostyle 41 other ends are fixed in claw 3 times.Promote driving lever 6, bearing 42 rolls along sidewall in helix groove, and axostylus axostyle 41 drives the tripod claw along " H " shape groove 11 synchronous expansions or contraction.See Fig. 3, the shape of helix groove on rotating disk 5 is through particular design, comprise first,

second end

52,53, by first end, 52 gradual change to the second ends 53, described first end 52 is near from rotating disk 5 centers of circle, and described second end 53 is far away from rotating disk 5 centers of circle, center of arc does not overlap with rotating disk 5 centers of circle, therefore, rotating disk 5 rotates the distance that can change between the web member 4 and rotating disk 5 centers of circle, realizes the stretching motion of claw 3 afterwards.When web member 4 during at first end 52, claw 3 is a contraction state, sees Fig. 5; Web member 4 is when second end 53, and claw 3 is a deployed condition, sees Fig. 4.Described first,

second end

52,53 with respect to distance of center circle from difference be that the tripod claw shrinks and the inner diameter range that launches.

Shell 1 surface, bidding chi 2 on second cavity 72.Scale 2 cooperates driving lever 6 and register pin 8, can show the diameter of claw 3 clamping filter sticks.Each scale on the scale 2 has all been represented the inner diameter value of tripod claw, and register pin 8 is detachable.Driving lever 6 is shifted the tripod claw onto maximum deployed condition earlier, and when the diameter of certain numerical value of needs, driving lever 6 moves to this numerical value position shown in the graduated

scale

2,8 pairs of driving levers of register pin, 6 location.

Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only.Any modification or partial replacement that does not break away from spirit and scope of the invention all should be encompassed in the middle of the claim scope of the present utility model.
