Abstract
The invention relates to a chain demounting device for demounting the driving chain of motor or non-motor vehicle, which comprises a screw and a concave shaped carriage; the screw has a threaded center hole and is screwed in the threaded hole of an end ear of the concave shaped carriage; the rotating arm part 5 of a thimble screw is screwed in the threaded center hole of the screw 1; the other endear of the concave shaped carriage is formed with a pin locking hole on the inner end face opposite to the thimble of the thimble screw. Advantages: 1, the invention not only realizes the reliable lo cking to the chain needing demounting, but also realizes easiness, rapid and high efficiency in chain demounting; 2, because the thimble screw is fitted with the screw with center threaded hole by screwing, the force applied on the thimble screw by the rotating arm is applied on the chain pin directly by the thimble, and forces the chain pin contacting the thimble to separate from the outer chain board; 3, the invention achieves the advantages of novel structure design, unique, simple, convenient for hand operation and long service life.
Description
Technical field
The present invention relates to a kind of chain rivet remover that is used for demountor motor-car, non-motor-driven driving chain, belong to chain rivet remover and make the field.
Background technology
Open notification number CN2535195Y, title " chain rivet remover " have the spill bearing, turn round the screw rod that has projection at screw head at an end of bearing, have the hole that adapts with projection in the another side and the screw rod corresponding position of bearing.Rotating screw bolt, the projection of screw rod are pushed down the chain articulated pin of chain, the chain articulated pin can be extruded the dismounting chain.There is weak point in it: the one, and this screw rod had both been thought fixedly chain on structure Design, want again to push up and tear chain open, but in the operation of reality, because the bearing pin that constitutes chain for protruding die shape, has no idea chain for convenience detach also just can't be realized in tearing open chain location therefore at all at all; The 2nd, the spill bearing does not have handle, can't use hand operated at all, and not only operation easier is big, and the dismounting chain is very difficult.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of both convenient locking chain, the chain rivet remover of chain for convenience detach again.
Design: in order to realize above-mentioned purpose of design.1, macaroni yarn hole screw rod be screwed in the silk hole of concave cradle one end ear and with the design that the macaroni yarn hole spins, be one of feature of designing of the present invention.The purpose of doing like this is: because macaroni yarn hole screw tip face has fluted, this groove can allow formation chain hinge pin die be positioned at it just and match with the bearing pin lock hole of concave cradle other end ear inner face, the end face that makes macaroni yarn hole screw rod plays the effect that fixes to clamp chain with dismantling between the bearing pin lock hole that chain hinge pin is locked in macaroni yarn hole screw rod and concave cradle other end ear inner face firmly.2, the swing arm portion of thimble screw rod is screwed in the design of hollow core silk hole screw rod, is two of the feature that designs of the present invention.The purpose of doing like this is: because the swing arm portion of thimble screw rod is screwed in the screw rod of hollow core silk hole and with the bearing pin that will dismantle all on same center line, the dismounting force that the thimble screw rod is produced is just on the central axis of bearing pin, therefore can be easily, quickly and easily bearing pin is ejected, reach the purpose of tearing chain fast open, and chain damage or dismounting situation of difficult can not take place.3, the design of carriage bottom handle is three of the feature that designs of the present invention.The purpose of doing like this is: during chain, can make things convenient for, hold easily chain rivet remover in dismounting, not only improve the efficient of dismounting chain effectively, and reduce the person's that tears the chain open labour intensity.
Technical scheme: chain rivet remover, it comprises screw rod and concave cradle, described screw rod is in macaroni yarn hole screw rod and the silk hole that is screwed in concave cradle one end ear, the swing arm portion 5 of thimble screw rod spins with macaroni yarn hole in the screw rod 1, and the other end ear inner face of concave cradle has bearing pin lock hole and relative with thimble in the thimble screw rod.
The present invention compares with background technology, and the one, not only realized will dismantling the positive lock of chain, and realized easily, fast, efficiently tearing open the purpose of chain; The 2nd, because the thimble screw rod is to spin with macaroni yarn hole screw rod and cooperates, the power that acts on the push rod screw rod by the rotation hand lever acts directly on the bearing pin of chain by thimble, forces the chain hinge pin that touches mutually with thimble to separate with outer plate; The 3rd, structural design novelty, uniqueness, simple, be convenient to manual operation and long service life.

Fig. 3 is a chain rivet remover swing arm schematic diagram.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1～3.Chain rivet remover, it comprises screw rod and concave cradle, carriage 2 bottoms are provided with handle 6.Described screw rod is in macaroni yarn hole screw rod 1 and the silk hole that is screwed in concave cradle 2 one end ears, the swing arm portion 5 of thimble screw rod spins with the macaroni yarn hole in the screw rod 1, and macaroni yarn hole screw tip face has fluted and has the bearing pin lock hole with the other end ear inner face of concave cradle 2 and matches.The other end ear inner face of concave cradle 2 has bearing pin lock hole and relative with thimble in the thimble screw rod, and the swing arm top in the thimble screw rod is provided with rotation hand lever jack 7, and the thimble 4 in the thimble screw rod is overall structure with swing arm portion 5.The hole of the other end ear inner face of concave cradle 2 is threaded bore and is screw thread with top heart borehole jack 3 and spins and cooperate, described screw rod 1, swing arm 5, top heart borehole jack 3 be positioned at same center line.
During use, hold the handle 6 of the concave cradle bottom of chain rivet remover, the another hand is entrapped in chain hinge pin one end of required dismounting in the top heart borehole jack 3, regulate macaroni yarn hole screw rod 1, make macaroni yarn hole screw tip face have fluted pinning (blocking) and will tear the chain hinge pin other end open, be plugged on hand lever on the rotary jack 7 by rotation, thimble 4 can be like a cork ejects the articulated pin (bearing pin) of chain in the thimble screw rod.
What need understand is: though the foregoing description is to the present invention's detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than to the restriction of mentality of designing of the present invention; any combination, increase or modification that does not exceed mentality of designing of the present invention all falls within the scope of protection of the present invention.
