Embodiment Construction

[0019] As shown in the figure, the dual spring reaction force structure of this railway signal relay includes a dual spring reaction force structure composed of two outer springs 3 and inner springs 6 with different stiffnesses arranged on a square-head screw rod, and a spring fixing cover 4. The spring reaction force structure composed of the square head screw 5, the nut and the armature 1, the inner spring 6 provides the reaction force at the beginning, and the outer spring 3 and the inner spring 6 provide the reaction force together when it moves to a certain displacement.

[0020] Reference figure 1 , The armature 1 acts under the action of the attraction generated by the magnetic field and the reaction force provided by the spring reaction structure 2.

[0021] Reference figure 2 , Two outer springs 3 and inner springs 6 with different stiffnesses are used to provide the reaction force. At the beginning, only the inner spring 6 provides the reaction force. After a certain peri...

Abstract

The invention discloses a dual-spring counter-force structure of a railway signal relay, which comprises a spring counter-force structure formed by a spring, a spring fixing cover (4), a square-head screw rod (5), a nut, and a keeper (1), and is characterized in that the spring is formed by an outer spring and an inner spring (6) with different stiffness arranged on the square-head screw rod; and at the beginning stage, the inner spring (6) provides a counter force, and in the case of movement to a certain displacement, the outer spring (3) and the inner spring (6) together provide the counter force. The defect that adjustability of counter-force features of a single-spring counter-force structure is not high can be solved, improvement of anti-vibration performance of the relay is facilitated, movement features of the keeper can be well ensured, and the dual-spring counter-force structure of railway signal relay has the advantages of reasonable and compact structure, good reliability and simplicity.

Description

Technical field [0001] The invention relates to a spring reaction force structure of a railway signal relay, in particular to a double spring reaction force structure of a railway signal relay, belonging to the technical field of low-voltage electrical equipment. Background technique [0002] Most of the existing railway signal relays adopt a single spring reaction force structure, which is less adjustable for the suction and reaction force coordination; the initial speed of the armature movement process is not high, and the speed is too high when closing, resulting in bounce phenomenon; single spring reaction force structure vibration The environment is too stable. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art. Aiming at the defects of the existing single spring reaction force structure of the existing railway signal relay, it provides a double spring reaction of a railway signal relay wit...
