Abstract

The utility model discloses a kind of stacked switch shells, including shell, the first throttle string holes and the second throttle string holes are offered on the shell, first throttle string holes includes preceding hole and rear hole, and the central axis of preceding hole is parallel with the central axis of the second throttle string holes, the central axis of rear hole intersects with the central axis of the second throttle string holes.By using above structure, the utility model provides a kind of stacked switch shell convenient for threading and demoulding.

Description

A kind of stacked switch shell

Technical field

The utility model relates to a kind of stacked switch shells, specially the stacked switch shell on motorcycle or electric vehicle etc. Body.

Background technique

Currently, usually all opening up on the stacked switch shell of motorcycle or electric vehicle etc., there are two throttle string holes, that is, supply two Throttle connecting line is each passed through, but since two throttle string holes are close to each other, and the central axis of the two throttle string holes is in phase Setting is handed over, therefore not only two throttle connecting lines will appear interference after passing through, but also in shell shaping and demoulding, also will appear mutually The case where interference, needs successively to be demoulded twice, reduces processing efficiency so as to cause the two throttle string holes.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of stacked switch shell convenient for threading and demoulding.

To achieve the above object, the utility model provides a kind of stacked switch shell, including shell, opens on the shell Equipped with the first throttle string holes and the second throttle string holes, the first throttle string holes includes preceding hole and rear hole, and the center of preceding hole Axis is parallel with the central axis of the second throttle string holes, the central axis phase of the central axis of rear hole and the second throttle string holes It hands over.

The beneficial effects of the utility model are: using the above structure, since the utility model is by the first throttle line therein Hole splits into preceding hole and rear hole, and keeps the central axis of preceding hole parallel with the central axis of the second throttle string holes, after The central axis of hole intersects with the central axis of the second throttle string holes, therefore is both convenient for throttle connecting line from the first throttle in this way It is penetrated in the rear hole of string holes, and it is connect when being pierced by from preceding hole with another throttle being pierced by the second throttle string holes Line keeping parallelism, to effectively avoid the occurrence of interference, similarly, when demoulding, also can effectively avoid the occurrence of the case where interfering, from And once to demould the processing that just can be completed to two throttle string holes.

It is also equipped with inwardly on hole and the inner wall of the second throttle string holes in arc before the utility model can be further arranged to Shape is arched the elastic slice of setting.By be arranged elastic slice, the throttle connecting line passed through can be formed elasticity pre-tighten positioning and it is effective It avoids forming friction between throttle connecting line and corresponding aperture inner wall.

The utility model, which may further be provided, is additionally provided with positioning region, the preceding hole and for the both ends of the elastic slice It is corresponding on the inner wall of two throttle string holes to offer the groove that location fit is constituted with the positioning region.By the positioning region with it is recessed The elastic slice can be fixed on the inner wall of corresponding aperture by the cooperation of slot.

The utility model, which may further be provided, forms the positioning region for the both ends end inward curl of the elastic slice.This Sample setting, structure is simpler, fixed stronger reliable.

The utility model may further be provided to be had multiple for the elastic slice, and is circumferentially uniformly arranged.In this way, Structure is more rationally symmetrical.

The utility model, which may further be provided, to be connected between the preceding hole and rear hole by arc surface transition.This Sample is more conducive to the progress of demoulding.

Detailed description of the invention

Fig. 2 is the portion the A enlarged drawing of Fig. 1；

Fig. 3 is the cross-sectional view of shell in the utility model.

Specific embodiment

A kind of stacked switch shell, including shell 1 are given as shown in Figure 1, 2, 3, and the first oil is offered on the shell 1 Door string holes 2 and the second throttle string holes 3, the first throttle string holes 2 include preceding hole 21 and rear hole 22, and the central axis of preceding hole 21 Line is parallel with the central axis of the second throttle string holes 3, the central axis of the central axis of rear hole 22 and the second throttle string holes 3 Intersection.It is connected between the preceding hole 21 and rear hole 22 by 23 transition of arc surface.

Using the above structure, hole 21 and back segment before being split into the first throttle string holes 2 therein due to the utility model Hole 22, and keep the central axis of preceding hole 21 parallel with the central axis of the second throttle string holes 3, the central axis of rear hole 22 Intersect with the central axis of the second throttle string holes 3, therefore is both convenient for rear hole of the throttle connecting line from the first throttle string holes 2 in this way It is kept when being penetrated in 22, and it being pierced by from preceding hole 21 with another throttle connecting line being pierced by the second throttle string holes 2 In parallel, to effectively avoid the occurrence of interference, similarly, when demoulding, also can effectively avoid the occurrence of the case where interfering, so that Primary demoulding just can complete the processing to two throttle string holes.

The elastic slice 4 of inside arc-shaped setting of arching also is equipped on preceding hole 21 and the inner wall of the second throttle string holes 3.It is described The both ends of elastic slice 4 are additionally provided with positioning region 41, corresponding on the inner wall of the preceding hole 21 and the second throttle string holes 3 to offer and institute State the groove 5 that positioning region 41 constitutes location fit.The both ends end inward curl of the elastic slice 4 forms the positioning region 41.Institute The elastic slice 4 stated has multiple, and is circumferentially uniformly arranged.By the way that elastic slice 4 is arranged, elasticity can be formed to the throttle connecting line passed through Positioning is pre-tightened, and can effectively avoid forming friction between throttle connecting line and corresponding aperture inner wall.
