Description

Hook pawl structure
Technical field
It the utility model is related to a kind of connection and hook pawl, it is especially a kind of to be used to connect the hook pawl knot of fork and lower fork on bicycle Structure.
Background technology
Bicycle or electric bicycle have upper fork and lower fork, and upper fork is connected with lower fork junction by hooking pawl, hook pawl For installing the rear axle of bicycle, rear axle is used for rim after installing.Rear axle and axis are passed by driving chain or driving belt Dynamic connection, and existing hook pawl structure is integral type structure, it is necessary to will when needing to install driving chain or driving belt Hook pawl to dismantle with rear axle, then carry out the installation to driving chain or driving belt again, install and repair and be cumbersome.
The content of the invention
The purpose of this utility model is to provide one kind using split type hook pawl structure, installation and maintenance bicycle transmission chain Pawl structure is more easily hooked when bar or driving belt.
In order to achieve the above object, the technical solution of the utility model is:One kind hooks pawl structure, including hooks pawl body, hooks Lower hook pawl that pawl body includes being fixedly connected with lower fork, connector and pitch the contiguous block that is fixedly connected with upper, the lower hook pawl and Contiguous block is removably connected by connector, and lower hook pawl is provided with mounting groove.
It is respectively provided with the lower hook pawl and contiguous block and is respectively protruding into lower fork and upper fork hole convex origin or beginning.
The connector includes isolation boss, and the both sides for isolating boss are equipped with installation inserting end, install and are set on inserting end There is the first mounting hole, lower hook is respectively equipped with and filled the mounting hole that inserting end coordinates, the side wall of mounting hole on pawl and contiguous block Provided with the second mounting hole being used cooperatively with the first mounting hole.
After said structure, when the utility model needs to install and repairs driving chain or driving belt, as long as by under Hook pawl and contiguous block to disengage with connector, it is possible to expose installation gap, it is possible to which driving chain or driving belt are passed through into this The dismounting of individual installation gap or installation, without dismantling lower rear axle again, therefore install and repair very convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model use state figure.
Embodiment
The utility model is described in further detail below in conjunction with the embodiment that accompanying drawing provides.
Shown in Figure 1, one kind hooks pawl structure, including hooks pawl body 20, and hooking pawl body 20 includes being fixedly connected with lower fork 4 Lower hook pawl 1, connector 3 and with the upper contiguous blocks 2 that are fixedly connected of fork 5, the lower hook pawl 1 and contiguous block 2 can by connector 3 The connection of dismounting, and lower hook pawl 1 is provided with mounting groove 11.Improved mat can also be set in mounting groove 11, ensure the lock of bolt Tight effect.
It is shown in Figure 1, it is respectively provided with the lower hook pawl 1 and contiguous block 2 and is respectively protruding into 5 hole internal projections of lower fork 4 and upper fork End 6.Because lower fork 4 and upper fork 5 are fitting structures, therefore protruding end 6 can be respectively protruding into upper fork 5 and lower fork 4 during connection It is spacing accurate in hole, the end of upper fork 5 and lower fork 4 is then fixed on contiguous block 2 with by way of bolt or welding Hook on pawl 1.
Shown in Figure 1, the connector 3 includes isolation boss 31, and the both sides of isolation boss 31 are equipped with installation and stretched into End 32, installation inserting end 32 are provided with the first mounting hole 33, are respectively equipped with and dress inserting end on the lower hook pawl 1 and contiguous block 2 32 mounting holes 7 coordinated, the side wall of mounting hole 7 are provided with the second mounting hole 71 being used cooperatively with the first mounting hole 33.Isolate convex Platform 31 can separate lower hook pawl 1 and contiguous block 2, make to touch between the two.During installation, two installations of connector 3 are stretched Enter in the mounting holes 7 that end 32 is respectively protruding on lower hook pawl 1 and contiguous block 2, then by bolt through the first mounting hole 33 and the Two mounting holes 71, are allowed to connect, are easy for installation and removal.
Referring to shown in Fig. 1,2, because upper fork 5 and lower fork 4 are jag structure, therefore the utility model needs two and made together With.When mounted, axis 8 is arranged on one end of lower fork 4 to the utility model, and rear axle is arranged on mounting groove 11 by nut, And fixed by nut can.After lower hook pawl 1 and contiguous block 2 are connected by connector 3, a dismountable entirety is formed, Lower hook pawl 1 is fixedly connected with lower fork 4, and contiguous block 2 is fixedly connected with upper fork 5.Hook pawl body 20 of the present utility model is due to for can Split type structure is dismantled, it is necessary to when installing and repair driving chain or driving belt, as long as by lower pawl 1 and the contiguous block 2 of hooking with being connected Part 3 disengages, it is possible to exposes installation gap, it is possible to by driving chain or driving belt by this installation gap dismounting or Installation, without dismantling lower rear axle again, therefore install and repair very convenient.
Above-described is only preferred embodiment of the present utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these all belong to In the scope of protection of the utility model.
