Abstract
The utility model relates to a switch spring operation mechanism. The utility model is characterized in that the operation mechanism is composed of a four-link rod mechanism and a five-link rod mechanism in the mode of connection; one branch crank arm is shared by the four-link rod mechanism and the five-link rod mechanism; one side surface of one link rod in an interlink rod mechanism is provided with a tilting surface of which the upper part is provided with a clamp block or a clamp shaft, and a hinge position on the end is provided with a roller contacted with a cam in a spring energy accumulation mechanism. The mechanism of the utility model is also provided with a brake mechanism through which two link rods in the five-link rod mechanism can be locked when the two link rods are arranged on a dead position. The utility model uses one part to replace a plurality of original parts; accordingly, the structure of the operation mechanism is simplified, the volume is decreased, the cost is reduced, and the maintenance is convenient.
Description
The utility model is a kind of spring operating mechanism of power switch.
Many power switches adopt spring operating mechanism to handle, and existing spring operating mechanism is owing to its complex structure, so cause its volume very big, production cost is higher, bring its manufacturing and maintenance to be difficult for simultaneously.
The purpose of this utility model provides a kind of novel power switch spring operating mechanism, and it can overcome existing shortcoming in the prior art, makes designs simplification, volume-diminished.
The purpose of this utility model is achieved in that it comprises spring energy agency and operating mechanism, it is characterized in that operating mechanism is by a four-link mechanism and continuous the forming of 5-linked linkage, wherein a connecting lever is a common arm, a link rod side in the 5-linked linkage has the inclined-plane, top, inclined-plane is provided with a projection, and roller is housed in the hinged place, end, this roller contacts with cam in the stored energy mechanism, locked brake mechanism when also being provided with two link rods that make in the 5-linked linkage being in the dead-centre position in mechanism.
Above-mentioned said brake mechanism can be that a protrusion is adorned on connecting rod top in the 5-linked linkage, when connecting rod and roller rise to the dead-centre position it is blocked; Or be provided with elongation end at the link rod tail end that has the inclined-plane, and on coupled link rod, adorn a projection, when two link rods were in the straight line position, elongation end promptly was stuck on the projection, and mechanism is locked.
The utility model adopts above-mentioned link mechanism to realize the operational motion of switch, replaced original a plurality of parts with one of them part, so that the structure of operating mechanism obtains simplifying, make volume-diminished, because the simplification of structure brings the convenience of the reduction and the maintenance of cost of goods manufactured again.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic diagram of a vital part among the embodiment of the present utility model.
Fig. 3 to Fig. 5 is an operating principle schematic diagram of the present utility model.
Fig. 6 is the schematic diagram of brake mechanism in the utility model.
As shown in the figure, the 1st, cam, it is connected with spring energy agency, and obtains power thus and move, and the pivoted arm 5 among the figure, link rod 6 and pivoted arm 7 constitute a four-link mechanism, pivoted arm 7, link rod 8,11 and pivoted arm 12 constitute a 5-linked linkage, wherein pivoted arm 7 is a common arm, and roller 9 is equipped with in connecting rod 8 and 11 hinged place, and the link rod 8 in the 5-linked linkage as shown in Figure 2, its side has an inclined-plane A, and its afterbody has elongation end B.As shown in Figure 1, above above-mentioned inclined-plane, be provided with a projection 13, be used to limit the movement locus of link rod, in the middle of link rod 11, be provided with a projection 10, be used to block elongation end B, brake the motion of each link rod.The 5-linked linkage links to each other with switch by a pull bar 15, splits and puts line operate into, and the pivoted arm 5 in the four-link mechanism is a covering of the fan shape, and its side and a semiaxis 4 join, and semiaxis links the operation when pull bar 2 is used for separating brake by a bent plate 3 and pull bar 2.
Fig. 3 to Fig. 5 has represented the moving principle of doing of the present utility model, wherein shown in Figure 3 is the separating brake position, when carrying out energy storage by switching-in spring, driving cam 1 rotates, cam promotes roller 9 and moves upward, and when link rod 11 and 8 was pushed over the dead point, the elongation end of link rod 8 tail ends was blocked by fixture block 10, realizing closing a floodgate keeps (position as shown in Figure 4), and cam forwards original position (being the energy storage initial position) under the drive of spring mechanism afterwards.When the needs separating brake, pulling pull bar 2, drive semiaxis 4 by bent plate 3, making pivoted arm (being fanning strip) 5 drive link mechanism together rotates counterclockwise, link rod 8 according to specific orbiting motion, rotates counterclockwise pivoted arm 12 because the inclined-plane is subjected to the restriction of projection 13, drive pull bar 15 and move right, finish the separating brake action.
Brake mechanism of the present utility model also can promptly be provided with a projection 16 as shown in Figure 6 on five-bar mechanism, when connecting rod rises to this moment, it is blocked, and limits the action of connecting rod.
