Description
Technical field：
Fixture product mechanical field is the utility model is related to, refers in particular to a kind of modified clamp for preventing from loosening.
Background technology：
Clamp is often used in production and processing, it is a kind of fastening tool, the 4 axle serial verb constructions set by itself
Clamped object is clamped.
Clamp is when in use, it usually needs be fixed on a fixation means, then adjust clamp in chuck in pressure arm
In position.It will need to be fixed on below chuck by fixed object, then rotate the handle on clamp, pass through clamp itself
4 axle interlinked mechanisms, pressure arm is driven by rotational handle, makes pressure head compress object, object is fixed.State is compacted in object
When, using lever principle, now pressure arm is in a relatively steady state, except non-user rotates backward handle again,
Pressure arm can be driven to rotate, release and object is fixedly clamped.
For the clamp of this 4 axle interlinked mechanism due to simple in construction, application is very extensive, but its there is also certain
Deficiency.Because the clamp using 4 axle interlinked mechanisms is when object is compacted state, it is to make pressure arm be in one using lever principle
Individual relatively steady state.It is very small that the arm of force of handle is now acted on by pressure arm, pressure arm at all can not driving handle rotate,
So whole clamp is theoretically to be in a kind of state of stabilization.But in actual use, because clamp may pacify
Dress is fixed on any facility, if its facility fixed is in continuous shaking or inverted state, in such a case, hand
Handle may depart from original position under continuous vibration, certain deflection occur, after handle deflects certain angle, this
The stable critical condition of kind will be broken, and pressure arm may lose restriction, so as to cause clamped object to come off.

The utility model is further illustrated with reference to specific embodiments and the drawings.
As shown in Fig. 1-5, the utility model is a kind of modified clamp, and it includes：By base 1, handle 2, pressure arm 3 and connect
The four axle interlinked mechanisms that bar 4 is formed, wherein, described handle 2 is be hinged by handle fulcrum 20 and base 1, and described pressure arm 3 is logical
Overstress arm fulcrum 30 rivets with base 1, and the described both ends of connecting rod 4 rivet with handle 2 and pressure arm 3 respectively；By handle 2 along hand
The rotational band dynamic pressure arm 3 of handle fulcrum 20 rotates along pressure arm fulcrum 30, and the clamp also includes a lockup arm 5, described lockup arm 5
Elasticity is riveted on handle 2, is provided with the ejection position 51 of a protrusion, on described pressure arm 3 to position 51 should be ejected
Position is formed with corresponding stop position 31.Described handle 2, pressure arm 3, connecting rod 4 and lockup arm 5 is transported at grade
It is dynamic.
Load bearing component of the base 1 as whole clamp, it is made up of the symmetrical fixed seat of two panels, the shape between two fixed seats
Cheng Youke houses the storage tank 10 of pressure arm 3, extends in the bottom of base 1 to both sides formed with fixed plate, in being opened up in fixed plate
There is fixing hole 11.In use, base 1 is fixed on corresponding facility with the cooperation of fixing hole 11 by screw.
With reference to shown in Fig. 3, described handle 2 includes：Grip portion 21 and holder 22, holder 22 is by symmetrical jig arm structure
Into；Two jig arm of described holder 22 are sandwiched in outside base 1, and are passed through handle fulcrum 20 and riveted with base.For the ease of
User grips, in the outside installation PVC gum covers 210 of grip portion 21.Meanwhile in order to avoid the anglec of rotation of handle 2 is excessive, the bottom of at
Formed with salient point 12, this fixes 12 on the rotational trajectory of handle 2, plays and stops what handle 2 excessively rotated for the outer surface of seat 1
Function.
With reference to shown in Fig. 1,2,3, in the storage tank 10 of the described base 1 of described one end of pressure arm 3 insertion, and pass through pressure arm
Fulcrum 30 rivets with solid bottom 1；The one end of pressure arm 3 away from pressure arm fulcrum 30 is provided with a slide groove portion 32, is set in the slide groove portion 32
Can be along the pressure head 6 of slide.The pressure head 6 can utilize the lateral adjustments position of slide groove portion 32.Described pressure head 6 includes：Threaded shank
61st, the nut 62 being threadedly coupled with threaded shank 61, wherein passing through in described threaded shank 61 through the slide groove portion 32 on pressure arm 3
Threaded shank 61 is clamped in slide groove portion 32 by the nut 62 positioned at the upper and lower ends of slide groove portion 31；It is provided with the lower end of threaded shank 61
Pressing head seat 63.In addition, pad 64 is additionally provided between nut 62 and slide groove portion 32.Described pressing head seat 63 uses rubber material
Material, when clamp works, it will need to be compressed by fixed product by pressing head seat 63, so pressing head seat 63 can be prevented using elastomeric material
Only impression is caused to being compacted product.
Described one end of connecting rod 4 is riveted by rivet 41 and handle 2, and its other end is riveted by rivet 42 and pressure arm 3, and
And formed with a baffle plate 43 on described connecting rod 4.Connecting rod 4 is equally made up of two blocks of symmetrical sheet materials and connected by baffle plate 43
It is integrally formed.During installation, the first end that connecting rod 4 installs rivet 42 sandwiches pressure arm 3, is then riveted by rivet 42.So when
When clamp is in clamped condition, as shown in Figure 1, baffle plate 43 is just compressed on the upper surface of pressure arm 3, and backstop is produced to pressure arm 3
Effect.
Described lockup arm 5, connecting rod 4 are riveted with handle 2 by rivet 41；Set in lockup arm 5 close to the side of handle 2
There is an extending column 52, a back-moving spring 50 is sheathed on the extending column 52, and against between handle 2 and lockup arm 5.It is described
Lockup arm 5 on the distal end of extending column 52 is provided with a spacing preiection 53, lockup arm 5 acts in the elastic force of back-moving spring 50
It is spacing to lockup arm 5 by stop of the handle 2 to spacing preiection 53 down with the trend being turned out along rivet 41.
With reference to shown in Fig. 4, when the utility model is in clamped condition, the baffle plate 43 of connecting rod 4 first is just suppressed
In the upper surface of pressure arm 3, the effect of backstop is produced to pressure arm 3.Now the reaction force suffered by pressure arm 3 can not pass through the company of promotion
Bar 4 carrys out driving handle 2 and rotated.Simultaneously as described lockup arm 5 is flexibly riveted on handle 2, and the top on lockup arm 5
Go out on the stop position 31 that position 51 is just acted against on pressure arm 3, so 51 pairs of the ejection position of lockup arm 5 pressure arm 3 also forms limitation.Together
When, handle 2 limits because lockup arm 5 is blocked position 31, and handle 2 can not also rotate, even if whole clamp is in constantly vibrations
Environment, handle 2 will not also rotate, and whole device is at stable clamped condition.As shown in Figure 5, when needs open folder
During pincers, first have to press lockup arm 5, make lockup arm 5 overcome the elastic force of back-moving spring 50, rotate, now on lockup arm 5
Ejection position 51 will depart from the stop position 31 on pressure arm 3, and handle 2 loses restriction, it is possible to and turn right handle 2, and simultaneously
Drivening rod 4 deflects.Connecting rod 4 will start drag pressure arm 3 and be rotated up after certain angle is deflected, so as to which pressure head 6 be lifted
Rise, clamped product loses thrust, can be removed.
Certainly, specific embodiment of the utility model is the foregoing is only, is not to implement to limit the utility model
Scope, all equivalent change or modifications done according to construction, feature and principle described in present utility model application the scope of the claims, all should be wrapped
Include in present utility model application the scope of the claims.
