Embodiment Construction

[0011] See figure 1 , shows an elastic limit mechanism, its structure includes: retaining ring, upper shell, lower shell, large end cap, small end cap, switch position swing block, guide rod, spring, steel ball, light-transmitting cover , lights and other parts.

[0012] Such as figure 1 As shown: the upper housing 5 and the lower housing 12 are fixed by M3 screws and M3 nuts. The first guide rod 6 and the second guide rod 7 are vertically installed inside the upper casing, and grooves are provided on the guide rods. Two steel balls 9 are horizontally installed inside the upper casing, and a spring 8 is arranged between the two steel balls. support. When the guide rod moves vertically, the steel ball and the groove of the guide rod move relative to each other. When the steel ball enters the groove, with the help of the spring force, the steel ball and the groove are closely matched to play a position-limiting role. The upper end surface of the first guide rod 6 fixes the t...

Abstract

The invention relates to an elastic limiting mechanism. The elastic limiting mechanism comprises a housing and is characterized in that two guide rods are vertically installed inside the housing, the two guide rods are provided with grooves; the inside of the housing is provided with two limiting steel balls cooperating with the two guide rod grooves; a spring is installed between the two limiting steel balls; the upper ends of the two guide rods are respectively provided with end covers; and the lower ends of the two guide rods are respectively connected with a switch position swing block. During a guide rod motion process, the switch position swing block swings along with the guide rods. A turning switch is installed on a lower housing, a switch handle is arranged inside the switch position swing block, and when the switch position swing block swings, the turning switch is driven to perform handle position conversion. At the same time, the switch position swing block exerts limiting effects. The advantages are as follows: the structure is simple, and the operation is convenient and rapid. The pressing surface of the elastic limiting mechanism is provided with a protective back-up ring to prevent wrong operation so that operation safety is improved. The elastic limiting mechanism is internally provided with an indication lamp for realizing operation demands for a switch under different luminous environment conditions.

Description

technical field [0001] The invention relates to the improvement of a switch, in particular to an elastic limit mechanism, which is used to change the operation form of a toggle switch from a toggle type to a push type. technical background [0002] The handle of the toggle switch is short, and it is difficult for the operator to pull it; the toggle switch has no design to prevent misoperation, and it is easy to cause misoperation of the switch during actual use; in addition, the operator cannot clearly identify the position of the switch in a dark environment state. Therefore, it is urgent to improve the existing toggle switch operation form, and at the same time, it can indicate the position state of the switch. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the toggle switch in the prior art, and provide an elastic limit mechanism, which changes the operation mode of the toggle switch from the...
