Abstract
The utility model provides a chain wrench belonging to the technical field of machinery. The chain wrench solves the technical problem that the whole wrench can not stably work and is possible to slip when in use as the frictional force between a chain of the existing chain wrench and a part to be screwed is difficult to be ensured, and the wrench is not suitable for conditions with great moment as a casing pipe has fixed length and occupies large space and the arm of force can be not adjusted, and the like. The chain wrench comprises a handle and the chain; one end of the chain is fixedly connected with the inner end of the handle; the chain wrench is characterized in that the inner end of the handle is also fixedly provided with a locking head which can be clamped and connected between two sleeves of the chain; when the inner side of the chain suffers the force, the locking head can keep the clamping connection with the chain. The chain wrench has the advantages of good working stability, difficult slipping and flexile structure, the adjustable arm of force and adaptation to the condition with great moment.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of spanner, particularly a kind of Chain wrench.
Background technology
In the middle of the maintenance of equipment, many times to use the cylinder throw, for example dismantle filter, various pipeline, valve, common wrench can not be satisfied the demand, use traditional box spanner to impact to piece surface, shell as filter is generally plastics, cup is broken in the process of screwing easily, and the spanner versatility that carries is poor.
The Chinese patent file once disclosed a kind of chain and had worn pipe wrench [China Patent No. ZL200520101491.5; Granted publication CN2790684Y], it comprises sleeve pipe, is connected with chain on sleeve pipe, an outside that is hinged on sleeve pipe one end of chain, the other end of chain is passed sleeve pipe from the same end of the hinged chain of sleeve pipe and is passed from the other end.Chain wears pipe wrench can be according to the diameter difference of workpiece, arbitrarily shrink or emit the chain link of chain, chain is closely contacted with workpiece, when screwing, owing to the angle of screwing of sleeve pipe can not get loose chain link, thereby only must can conveniently turn on or screw the workpiece of different-diameters such as filter core with one pair of spanner.
Chain wears pipe wrench the chain fixed mechanism is not set, during use only by sleeve pipe screw the fixed angle chain, chain is difficult to assurance with the frictional force of being screwed between the part, skidding may appear in whole spanner job insecurity in use.And casing length fixes, and it is big to take up space, and the arm of force can't be regulated, and is not suitable for big moment situation.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist at existing technology, and a kind of good operating stability, non-slip Chain wrench are provided.
The purpose of this utility model can realize by following technical proposal: a kind of Chain wrench, comprise handle and chain, one end of described chain and the inner end of handle are connected mutually, it is characterized in that, also be installed with a locking head between two sleeves that can be connected to chain on the inner end of described handle, and when chain inboard when stressed described locking head can keep fixing with described chain and be connected.
The chain of this Chain wrench can adopt hinged connected mode and handle inner end to be connected.Locking head plays a part fixedly chain when Chain wrench uses, according to the diameter of being screwed part, locking head can be connected to the position, sleeve gap of diverse location, regulate the circle diameter that chain surrounds, make spanner and screwed part to adapt the chain good rigidly, be enclosed within screwed on the part after, frictional force between the two is big, and is non-slip when screwing, good operating stability.
In above-mentioned a kind of Chain wrench, the head of described locking head is wedge shape, and slightly to the outer end of handle lateral bending song.The head of locking head is connected between two sleeves of chain during use, and the stressed back of spanner locking head keeps fixing with chain and is connected; The head of wedge shape has the auto lock function, and chain fixes to be connected on the locking head and can not get loose.
In above-mentioned a kind of Chain wrench, be arranged with extension rod on the described handle, be provided with the adjustment structure that can adjust the handle overhang between described extension rod and the handle.The time spent can not taken in extension rod with handle, saves the space; Can guarantee that Chain wrench has the sufficiently long arm of force in pulling the part process by the overhang of adjustment structure joystick during use.
In above-mentioned a kind of Chain wrench, described adjustment structure comprises the gathering sill that is opened on the handle, is equipped with bolt on the described extension rod, and described bolt passes above-mentioned gathering sill, and the head that described bolt is positioned at the extension rod opposite side is bolted with nut.Unclamp nut, the extension rod that is equipped with bolt can slide along gathering sill; After screwing nut, the fixed relative position of extension rod and handle has played the effect of regulating whole chain decreased food.
In above-mentioned a kind of Chain wrench, described adjustment structure comprises several locating holes that are opened on the handle, it is evenly distributed that described locating hole is a straight line, be equipped with alignment pin on the described extension rod, alignment pin be plugged on the above-mentioned locating hole by the relative position of adjusting above-mentioned handle and extension rod.When regulating the chain decreased food, extract alignment pin, adjust the position of handle and extension rod, alignment pin is inserted locating hole; Plug conveniently connected reliable when alignment pin connected adjustment during work.
In above-mentioned a kind of Chain wrench, described chain is a short pitch roller chain.Short pitch roller chain be normal pitch and roller outer diameter ratio less than 2 and roller outer diameter less than the roller chain of chain plate height, the adjustable range of the circle diameter that chain surrounds is wider, the part that is fit to screw is more.
In above-mentioned a kind of Chain wrench, described chain is single chain.
In above-mentioned a kind of Chain wrench, described chain is a double strand chain.
Compared with prior art, the advantage of this Chain wrench is: locking head is reliable to the location of chain when 1, using, the Chain wrench good operating stability; 2, the chain and the frictional force of being screwed between the part are big, are difficult for skidding; 3, Collapsible structure, the arm of force can be regulated, and can adapt to big moment situation.
