Abstract
The existing handle type speed regulation controller has larger rotating operation force when in use, and the steel rope which is detached after use can only be scrapped. The utility model provides a pair of handle formula speed governing controller, the sliding flat key is connected the back through convex-concave interlock form and the space curve on the overcoat inner wall and is fixed and slide in the sliding groove that the endotheca set up on the surface, and the sliding flat key that is linear motion directly pulls the derailleur motion through manipulating the steel cable, and the revolving force of just greatly reduced handle speed regulator is adjusted to angle of rise and helical pitch, improves the sensitivity of derailleur. Novel structure and convenient operation.
Description
The utility model belongs to the speed setting controller of bicycle.
Existing gripping type speed setting controller, rotary manipulation power is bigger during use, and the steel cable that disassembles after the use can only be scrapped.
The purpose of this utility model is at above-mentioned deficiency, and a kind of later-model speed setting controller is provided, and it can more help improving the fixed shelves of calibration precision, reduces latching force and speed control operating effort, has improved group accuracy that the chain device puts in place greatly.
The utility model is realized in the following manner: the slip flat key by convex-concave interlock form be fixed on after space curve on the outer casing inner wall is connected in the cover surface go up in that be provided with and slide slot the utility model parallel axes and slide, an end of handling steel cable is fixed in the groove of slip flat key end, and the other end directly passes (back) group chain device before the external connection along axis direction from nearby bottom.Rotary sleeve (or interior cover) drives the slip flat key and carries out straight-line motion along axis direction in the slide slot of interior cover, dials the accurately group chain of chain device by (back) before the mobile drive of handling steel cable.
The utility model is fixed on the handlebar transverse tube by collet, steel cable need not twine and be crooked and directly pass externally, and lift angle and the helical pitch of adjusting space curve (cam or groove curve) just can make the rotational force of handle governor reduce and improve the sensitivity of group chain greatly.The utility model is simple for structure, compact, operation is light.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation.
Fig. 2 is an axially cutaway view of the utility model overcoat (1).
As Fig. 1, shown in 2, the utility model is by overcoat (1), interior cover (2), slip flat key (3), ratchet (4), compact heap (5) constitutes, be fixed on after slip flat key (3) is connected by the space cam curve (10) on the groove (9) on the slip flat key (3) and overcoat (1) inwall on interior cover (2) surface and slide in setting and the slide slot (6) the utility model parallel axes, an end of handling steel cable (8) is fixed in the groove (7) of slip flat key (3) end, and the other end directly passes external connection along axis direction from nearby bottom and dials the chain device.
The space curve interlock form of slip flat key of the present utility model (3) and overcoat (1) inwall also can adopt following method, promptly is designed to projection on slip flat key (3), and the space curve on overcoat (1) inwall is designed to groove.
As revolving part, interior cover (2) is as connecting element in the utility model as overcoat (1), and rotary sleeve (1) can make slip flat key (3) do straight-line motion; As overcoat (1) as connecting element, interior cover (2) is as revolving part, cover (2) can make slip flat key (3) do straight-line motion equally in the rotation.
Claims (5)
1, a kind of gripping type speed setting controller, comprise overcoat (1), interior cover (2), ratchet (4), compact heap (5), the flat key (3) that it is characterized in that sliding slides with being fixed in the slide slot (6) that is provided with on interior cover (2) surface after space curve on overcoat (1) inwall is connected by convex-concave interlock form, an end of handling steel cable (8) is fixed in the groove (7) of slip flat key (3) end, and the other end directly passes external connection along axis direction and dials the chain device.
2, a kind of gripping type speed setting controller according to claim 1, the interlock form of flat key (3) and the space curve of overcoat (1) inwall of it is characterized in that sliding can be that the slip flat key is provided with groove (9), the space cam curve (10) that overcoat (1) inwall is provided with.
3, a kind of gripping type speed setting controller according to claim 1, the interlock form of flat key (3) and the space curve of overcoat (1) inwall of it is characterized in that sliding also can be that slip flat key (3) is provided with projection, and overcoat (1) inwall is provided with space groove curve.
4, according to the arbitrary described a kind of gripping type speed setting controller of claim 1 to 3, it is characterized in that overcoat (1) as revolving part, interior cover (2) is as connecting element.
5, according to the arbitrary described a kind of gripping type speed setting controller of claim 1 to 3, it is characterized in that overcoat (1) as connecting element, interior cover (2) is as revolving part.
