Abstract
The utility model relates to a multistage switch which is formed by that a seat and a movable contact are connected through a shaft, wherein, the plane of the seat is provided with a platform, and the center of the seat is provided with a shaft hole; a plurality of cam bearings are radially and uniformly distributed on the platform centered with the shaft hole as a center; the cam bearings divide the platform into many pairs of zones symmetrical with a shaft center, wherein, contacts are not arranged in a pair of zones, and contacts are arranged in the residual zones according to different lamp fittings; lamp caps in the lamp fittings are respectively connected to the corresponding contacts; the central part of the movable contact is provided with a shaft hole, and positions of both ends corresponding to fixed contacts are provided with contacts. The utility model has the advantages of simple structure, reliable work and convenient operation.
Description
The utility model is a kind of multi-gear on-off, and the pendent lamp, the wall lamp that are particularly useful for having many lamp holders are suitable for.
Existing switch can only be realized simple on-off action, and this switch is used to have the pendent lamp of many lamp holders, during light fixtures such as wall lamp, perhaps connects whole lamp holders, perhaps disconnects whole lamp holders, and the brightness of these light fixtures can not be adjusted.
The purpose of this utility model is to provide a kind of multi-gear on-off, can connect different lamp holders selectively, thereby adjusts brightness of illumination.
Multi-gear on-off described in the utility model is to be formed by connecting with one by base, movable contact, wherein base plane is established a platform, its center is an axis hole, be the protruding beam of the radial even distribution even number bar in center with the axis hole on this platform, these protruding beams are separated into this platform some to the zone about the axle center symmetry, do not establish the contact in the wherein a pair of zone, in all the other zones, the contact is set according to different lamps, each lamp holder in the light fixture promptly is connected on the corresponding contact, the centre of movable contact is established an axis hole, and two ends and fixed contact corresponding position are the contact.
Owing to connect with axle, movable contact can relatively rotate, thereby enters each to the zone, if this is to non-contact in the zone, then all lamp holders all cut off the power supply, realization is turned off the light, and when this had contact in to the zone, the lamp that is connected on these contacts promptly can be energized, movable contact turns to diverse location, can light different lamp holders, the quantity and the power of the lamp that is connected on each contact rationally is set, can realize the open and close and the brilliance control of many gears of light fixture.
Advantage of the present utility model is simple in structure, and reliable operation is easy to operate.
The utility model is described in further detail below in conjunction with embodiment:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A-A cut-away view of Fig. 1
Fig. 3 is the structural representation of the utility model base
Fig. 4 is the relative position schematic diagram that shows shift fork and shifting block among the utility model embodiment 2
Embodiment 1: the structure of many driving switch shown in the present embodiment wherein, becomes totally 8 zones about four couple of axis hole symmetry by four protruding beams (4) with base (2) plane separation as shown in Figure 1, the cross sectional shape of each protruding beam (4), as shown in Figure 2.Have in above-mentioned four pairs of zones and do not establish the contact in a pair of zone, other three couple respectively establishes the live wire that a contact (1) is used to connect lamp holder in totally six zones, as shown in Figure 3.Power firestreak is connected central shaft (10) bottom.The movable contact that adopts in this example (5) is an arc flexure strip, establish ratchet (a 6) the center that has 8 teeth at its back of a bow place and be one with hole, the corresponding garden of base upper shaft hole, be used to be enclosed within central shaft (10).The plectrum that uses in this example (7) is sleeved on the central shaft (10), and a side that contacts with ratchet (6) on the movable contact (5) at it is provided with and the corresponding ratchet of this ratchet, and this plectrum and stay rod (12) are fixed together.Present embodiment is established a spring (9) and compressing tablet (11) in stay rod (12) top, one end of this spring (9) is fixed on the stay rod (12), the other end is fixed on the compressing tablet (11), and the tension force of this spring (9) can guarantee that ratchet positive engagement and movable contact (5) reliably contact with fixed contact (1).And when stay rod (12) rotated, this spring can produce moment of torsion on (9), and when unclamping backguy, this moment of torsion resets stay rod (12), gets ready for spur backguy next time.For guaranteeing Electrical Safety, the described many driving switch of present embodiment also comprise the upper casing (3) that a usefulness insulating material is made.
In this example, matching used lamp is 5 lamp holders, and wherein lamp (13
