Abstract

The utility model relates to a chain rivet remover for removing driving chains of locomotive cars and non-mechanized vehicles. The chain rivet remover comprises a screw and a concave bracket, whereinthe screw is a hollow thread hole screw and is screwed in a thread hole of an end ear of the concave bracket, a rotary bar part 5 of a thimble screw is screwed with the hollow thread hole in the screw1, and a pin shaft locking hole is arranged on the inner end surface of the other end ear of the concave bracket and is opposite to the thimble in the thimble screw. The chain rivet remover has the advantages that the chain rivet remover not only realizes reliably locking chains which need detaching, but also realizes the purpose of removing chains easily, rapidly and efficiently, secondly, sincethe thimble screw is screwed and matched with the hollow thread hole screw, the chain pin shaft contacted with the thimble and an outer chain plate are separated through rotating force of a hand barapplied on a post rod screw and directly applying the force on the pin shaft of the chains through the thimble, thirdly, the structure and design are novel, unique, simple, and is convenient for manual operation, and the service life is long.

Description

Chain rivet remover

Technical field

The utility model relates to a kind of chain rivet remover that is used for demountor motor-car, non-motor-driven driving chain, belongs to chain rivet remover and makes 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 utility model.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, be the utility model design feature two.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, be the utility model design feature three.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 utility model is compared 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.

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 utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
