Description
Technical field
The utility model relates to the walking-replacing tool such as bicycle, child's bicycle field, particularly a kind of quick detach jockey pulley device.
Background technology
Children for learning by bike generally need to be by other people's auxiliary balance, and in this case, auxiliary people is very arduous, and in the process of begining to learn riding bicycle, it is very common thing that wrestling is fallen, and particularly for children, has certain potential safety hazard.For this reason, occurred some auxiliary devices on market, modal is jockey pulley bar is installed on child's bicycle trailing wheel both sides two less auxiliary wheels by bolt, and in the time of riding bicycle, auxiliary wheel can support to ground, avoids falling.In order to dwindle packing measurements, in the time that whole bicycle needs packed and transported, jockey pulley and vehicle frame divide often and are arranged, just user need to can carry out dismounting operation by the dismantling devices such as spanner, pliers, and operation inconvenience.And children grasp balance, after driving a light carriage on a familiar road, just jockey pulley can be disassembled, become two-wheel children bicycle.But problem is, use after a period of time, as the reasons such as bolt gets rusty cause more difficult that the dismounting of jockey pulley becomes.Also have on the market some device for quickly disassembling, but problem is, the complicated structure of these device for quickly disassembling, and the part exposing is more, and maloperation easily occurs.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of compact conformation is provided, is difficult for occurring all very convenient, quick detach jockey pulley devices of putting in place and having felt of maloperation, installation and location.
The technical scheme in the invention for solving the above technical problem is: a kind of quick detach jockey pulley device, comprise vehicle frame, be installed on the Connection Block on vehicle frame, for jockey pulley bar and the detent mechanism of jockey pulley are installed, described detent mechanism comprises the mount pad that is installed on jockey pulley bar end, be provided with the mount pad in quartet connection hole, push rod, steel ball and spring, one end of described mount pad is the seat that is threaded being connected with described jockey pulley bar, the other end of described mount pad is and the quartet connection head coordinating of pegging graft of the quartet connection hole on Connection Block, described mount pad is provided with the through hole axially running through, described pusher slide is actively tied in described through hole, and be located at the button evagination of push rod one end in the end face of the described seat that is threaded, the outer circumference surface of described push rod is provided with the mounting groove matching with steel ball, described mounting groove is made up of the first mounting groove arranging continuously and the second mounting groove, and the degree of depth of the first mounting groove is less than the degree of depth of the second mounting groove, and one side of steel ball is embedded in the first described mounting groove in the time that jockey pulley bar assembles, in the time that jockey pulley bar separates, one side of steel ball is embedded in the second described mounting groove, the corresponding mounting hole matching with steel ball that is provided with on the sidewall of described quartet connection head, and the part spheroid of described steel ball opposite side by described mounting hole evagination in a quartet connection sidewall, the hole wall in described quartet connection hole is uniformly distributed circumferentially four for being embedded the deep-slotted chip breaker of steel ball opposite side, described spring fit is installed on the outer wall of described push rod, and one end of spring is butted on described button, and the other end of described spring is butted on the inwall of mount pad.
Compared with prior art, the utility model has the advantage of: on the Connection Block of this quick detach jockey pulley device, offer quartet connection hole, one end of mount pad is the seat that is threaded being connected with jockey pulley bar, the other end of mount pad is and the quartet connection hole quartet connection head coordinating of pegging graft, and detent mechanism is by steel ball and positioning in mounting groove and quartet connection hole coordinating of deep-slotted chip breaker.In the time that jockey pulley need to be installed, only need be by the quartet connection hole of jockey pulley axle the quartet connection phase fit with mount pad, and can by the chimeric positioning instant of steel ball and deep-slotted chip breaker.When jockey pulley bar needs dismounting, press the button, button drives push rod to move forward, at this moment, steel ball enters the second mounting groove from the first mounting groove, because the degree of depth of the first mounting groove is less than the degree of depth of the second mounting groove, be that steel ball reduces from the spherical part of mounting hole evagination, steel ball is deviate from the deep-slotted chip breaker in quartet connection hole, and Connection Block separates with mount pad, installs and removes all very convenient.Because button is evagination in the end face of the seat that is threaded, be difficult for occurring maloperation.And due to the structure that has adopted quartet connection head and quartet connection hole to match, the deep-slotted chip breaker for chimeric steel ball in cubic hole is also four, that is to say that any insertion quartet connection steel ball all can locate, locate very conveniently, and put in place and feel.
As preferably, the first described mounting groove and the side of the second mounting groove are equipped with the inclined-plane for leading.Like this, entering of steel ball is more smooth, more convenient to operate.
As preferably, four sidewalls of described quartet connection head are equipped with transition tangent plane.Like this, can effectively avoid interfering, operate more convenient.
As preferably, the hole wall in described quartet connection hole is circular-arc transitional slot along being circumferentially with four.Like this, can effectively avoid interfering, operate more convenient.
As preferably, the surrounding of a described quartet connection front end face is equipped with arc surface.Like this, can effectively avoid interfering, operate more convenient.
As preferably, described mount pad is provided with sheathing near button place.Like this, can further avoid occurring maloperation.
