Abstract
The utility model relates to a chain-disassembling device, in particular to the chain-disassembling device for a bicycle and a motor cycle. The chain-disassembling device comprises a working platform, a main seat, fixing devices, a spiral pressing shaft, and a force-adding bar. The chain-disassembling device is characterized in that the working platform and the main seat are assembled together through the fixing devices. A groove is formed at the front end of the working platform, and a pin outlet is formed in the middle of the groove. The front section of the spiral pressing shaft is provided with a pin which is matched with the pin outlet, and a threaded hole is formed at the front end of the main seat. The spiral pressing shaft is inserted inside from the threaded hole, and the pin at the front section of the spiral pressing shaft is aligned at the pin outlet. The force-adding bar traverses the spiral pressing shaft from the middle upper portion of the spiral pressing shaft. The chain-disassembling device overcomes the problems that when a knocking method is used, a hand is easily knocked, when a common tool extruding method is used, alignment is not easy to achieve and sliding is easy to occur and the like, and effects that chain disassembling is safe, easy, convenient and fast are achieved.
Description
Technical field
The utility model relates to a kind of chain device of tearing open, particularly a kind of device of tearing bicycle and motorcycle chain open.
Background technology
Current, the time that the motorcycle bicycle chain is ridden has been grown chain and also can elongate, chain has been grown by bike can jump chain, seriously also can cause the chain rupture phenomenon, occurs suddenly then easily generation accident of chain rupture phenomenon during driving, therefore occur for solving this phenomenon, several joints of chain must being dismantled, the method for tearing chain open has two kinds: a kind of is the method for beaing, and a same large iron staff with the chain pin is aimed at the chain pin beat, make its pin from the below out, thus removal; Be to use the general tool extrusion in addition, with a kind of instrument of U font, chain put into the inner end, a spiral last item backspin of top, the spiral last item is aimed at the chain pin it is extruded from the lower end aperture.All there is defective in these the two kinds methods of unloading, and the method for beaing easily knocks hand, and the general tool extrusion is difficult for aligning and slips out easily, and dismounting is relatively more difficult.
Summary of the invention
The purpose of this utility model provides a kind of chain device of tearing open, reaches to unload chain safety, effect easily and efficiently.
The technical solution adopted in the utility model is: tear chain device open, it comprises workbench 1, the seat of honour 2, fixture 3, spiral last item 4, afterburning rod 5, it is characterized in that: workbench 1 is assembled together by fixture 3 with the seat of honour 2, described workbench 1 front end is fluted 6, is provided with out pin-and-holes 7 in the middle of the groove 6; Described spiral last item 4 leading portions have and the pin 8 that goes out pin-and-hole 7 and be complementary; The described seat of honour 2 front ends have screwed hole 9; Described spiral last item 4 inserts from screwed hole 9, and the pin 8 of spiral last item 4 leading portions is aimed at out pin-and-hole 7; Afterburning rod 5 passes across from top intermediate conveyor screw last item 4.
After described workbench 1 assembled with the seat of honour 2, front end became horizontal U font or Contraband font.
Described groove 6 is middle in the arc-shaped.
Described fixture 3 can be screw.
The beneficial effect that the utility model is obtained is: when using the utility model to tear chain open, only need chain is put on the workbench, the profile of Chain link for chain grate circular arc is embedded in the groove centre of workbench, by afterburning rod the spiral last item is rotated down, the chain pin is pushed by the pin of spiral last item leading portion, squeeze and to be forced out going out pin-and-hole, namely finished and torn chain open.The utility model has overcome when tearing chain open, and the method for beaing easily knocks hand, and the general tool extrusion is difficult for the problems such as aligning slips out easily, reach unload chain safer, easily, effect easily and efficiently.
Description of drawings
Fig. 1 is that the utility model is torn chain device open and assembled positive two and survey views;
Fig. 2 is that the utility model is torn chain device open and decomposed positive two and survey views;

Concrete accompanying drawing indicates as follows: 1. workbench, and the 2. seat of honour, 3. socket cap screw, 4. spiral last item, 5. afterburning rod, 6. groove 7. goes out pin-and-hole, 8. pin, 9. screwed hole.
Specific embodiments
Such as Fig. 1～4, tear chain device open, it comprises workbench 1, the seat of honour 2, fixture 3, spiral last item 4, afterburning rod 5, and it is characterized in that: workbench 1 is assembled together by fixture 3 with the seat of honour 2, and after workbench 1 assembled with the seat of honour 2, front end became horizontal Contraband font; Described workbench 1 front end is fluted 6, and is in the arc-shaped in the middle of the groove 6, is provided with out pin-and-hole 7; Described spiral last item 4 leading portions have and the pin 8 that goes out pin-and-hole 7 and be complementary; The described seat of honour 2 front ends have screwed hole 9; Described spiral last item 4 inserts from screwed hole 9, and the pin 8 of spiral last item 4 leading portions is aimed at out pin-and-hole 7; Afterburning rod 5 passes across from top intermediate conveyor screw last item 4.Groove 6 is middle in the arc-shaped.Fixture 3 is screw.
When using the utility model to tear chain open, only need chain is put on the workbench, the profile of Chain link for chain grate circular arc is embedded in the groove centre of workbench, by afterburning rod the spiral last item is rotated down, the chain pin is pushed by the pin of spiral last item leading portion, squeeze and to be forced out going out pin-and-hole, namely finished and torn chain open.The utility model has overcome when tearing chain open, and the method for beaing easily knocks hand, and the general tool extrusion is difficult for the problems such as aligning slips out easily, reach unload chain safer, easily, effect easily and efficiently.
