Description

A kind of annular clamp

Technical field

The utility model belongs to hand-operated tools correlative technology field more particularly to a kind of annular clamp.

Background technique

Production is worked, often needs to be removed transfer sphere, column, ring using annular clamp in life, but conventional Annular clamp be all made of two hinged semi-circular arc pieces, the radius of semicircle arcs is fixed, and clamps object The diameter of body is different, and when clamping object every time, is only in contact there are two stress bite with object, and bite position It is not necessarily symmetrically, when weight of object is larger, the chucking power needed will also be increased accordingly, and otherwise clamped object is easy It falls off from clamp, the degree of fatigue of user's hand in use is very big, and biggish clamping force is easy to make object again Body deformation is serious or damages object.

Utility model content

Contact point is few when to overcome the problems, such as existing annular clamp to clamping object and is unevenly distributed, and the utility model mentions For a kind of annular clamp, the utility model structure is simple, easy to use, has equidistant multiple spot pressure, clamps, offloading functions.

Technical solution provided by the utility model is: a kind of annular clamp, including integrated ring and swivel hook, the one The inside of swivel hook is arranged in ring, and integrated ring is coaxial with swivel hook, and integrated ring is enclosed construction, and swivel hook is open structure, Swivel hook includes multiple head and the tail successively hinged curved rod, and every two curved rod hinged place is hinged with a crank simultaneously, The other end of crank is hinged on integrated ring, and the crank end of integrated ring side has the claw of arc, the length of each crank Identical, the angle between every two adjacent crank is equal, the oriented swivel hook of crank band of the swivel hook indentation, there side The flexible handle of outer extension is connected with fixed handle on integrated ring corresponding to swivel hook notch.

Fixture block is connected on the claw, the axis of the fixture block is vertical with the plane where the integrated ring； The flexible handle and fixed handle is cylindrical structure, and the outside of flexible handle and fixed handle has anti-slip layer； The fixed handle and integrated ring is in the same plane.

The utility model has the following beneficial effects: the utility model when clamping has the object of circular cross-section, has equidistant Multiple spot pressure clamps, offloading functions, so the utility model is more firm when clamping object, it is not easily to fall off, because bite Increase, so that chucking power becomes smaller, reduces the degree of fatigue of worker；The utility model has certain scope of application, can clamp Sphere, column, the ring of different-diameter；The utility model is suitable for center except material part has circular cross-section simultaneously Object, when the outer profile of object is irregular, and when common clamp block difficulty or outside is all wrapped no stuck point, this Clamp in utility model can be supported from the inside of object clamps object, and then is loaded and unloaded, compressed or shifted.

Specific embodiment

The utility model is described further below in conjunction with attached drawing:

The present embodiment includes integrated ring 2 and swivel hook, and the integrated ring 2 is on the inside of swivel hook and coaxial with swivel hook, Integrated ring 2 is enclosed construction, and swivel hook is open structure, and swivel hook includes the connecting rod 1 of multiple head and the tail successively hinged arc, 1 hinged place of every two curved rod is hinged with a crank 3 simultaneously, and the other end of crank 3 is hinged on integrated ring 2, integrated ring 2 3 end of crank of side has the claw 31 of arc, and the length of each crank 3 is identical, the folder between every two adjacent crank 3 Angle is equal, and the crank 3 of the swivel hook indentation, there side is with the flexible handle 4 extended outside oriented swivel hook, swivel hook notch Fixed handle 5 is connected on corresponding integrated ring 2, the fixed handle 5 and integrated ring 2 in the same plane, change and live Angle between fixed handle 4 and fixed handle 5 can make integrated ring 2 and swivel hook that circumferential relative rotation occur, at this time claw 31 length stretched out in integrated ring 2 change, and then have adapted to the clamping of the circular object of different-diameter.

The loading method of the present embodiment chucking power can directly be applied by manually, as shown in Figure 1, ought manually apply chucking power, When making the angle α between flexible handle 4 and fixed handle 5, each vertex of claw 31 is real to the outer circle multiple spot that diameter is M at this time Existing pressure relief function；As shown in Fig. 2, ought manually apply chucking power, make the angle β between flexible handle 4 and fixed handle 5 When, pressure relief function is realized to the outer circle multiple spot that diameter is N in each vertex of claw 31 at this time.

The utility model is by changing the angle between flexible handle 4 and fixed handle 5, it can be achieved that with circular cross-section The various functions such as the clamping of object, equidistant multiple spot pressure, unloading.

Change the quantity of compression point by changing the quantity of crank 3,3 quantity of crank is more, and compression point quantity is more.

Change the maximum gauge of clamping circle by changing the internal diameter of integrated ring 2, the internal diameter of integrated ring 2 is bigger, clamping circle Diameter it is relatively bigger.

Change the artificial size for applying chucking power by changing the length of two handles, according to lever principle, theoretically Handle is longer, and the chucking power manually applied is smaller.

In order to increase the comfort level that worker holds handle, the flexible handle 4 and fixed handle 5 are cylindrical knot Structure, in order to reduce it is hand-held during the probability that falls off of handle, the outside of flexible handle 4 and fixed handle 5 has anti-slip layer.

In order to further increase the scope of application of the utility model, as shown in Figure 3,4, it is connected on the claw 31 Fixture block 6, the axis of the fixture block 6 is vertical with the plane where the integrated ring 2, applies it and is removing material portion with center Point, and except the section of material part is on circular object.When the outer profile of object is irregular, when common clamp block difficulty, or When being that outside is all wrapped no stuck point, the fixture block 6 in the utility model protrudes into held object center, from the inside of object Object is supported, and then is loaded and unloaded or is compressed.
