Abstract
The utility model provides a relay installation structure, which uses integrative screw and nut. The problem needed to be solved is: a pole bolt is arranged in the iron core of the magnetic circuit assembly of the relay. A contact assembly, a splint and a model distinction cap are arranged on the pole bolt, and orderly fixed by three nuts. Three nuts, which are of the same type and have the same torsion, are screwed into one screw. The former nut can be loosened by the torsion of the later nut, produced in screwing, so that the contact assembly and the magnetic circuit assembly are to become flexible. The key point of the utility model is: a screw of the integrative screw and nut is adopted. The magnetic circuit assembly is positioned in the positioning hole on the base. Therefore, the magnetic assembly can be prevented from being loosened. The model distinction cap is fixed to the base by the combination of a screw and a nut of integrative screw and nut. The usage of the utility model is: to be used in the rail signal relay.
Description
Technical field
The utility model relates to a kind of relay mounting structure that uses incorporate bolt and nut.
Background technology
The AX series relay that railway signal uses by pull bar with magnetic circuit assembly and node component couple together the back, be installed on the base and constitute again.Concrete grammar is: two screws are arranged on the yoke of magnetic circuit assembly, with two nuts and two " headless screws " contact bracket on the contact unit and yoke are fixed together; And then with two nuts with clamping plate are installed are fixed on the relay base; With two nuts the type lid is fixed on the base more at last.The defective that exists is: be screwed into three identical nuts on a bolt, three torsion that nut produced are identical, the torsion that the nut of back produces when tightening can draw pine to the nut of front, cause contact unit and magnetic circuit assembly loosening, because the firm performance of contact unit and magnetic circuit assembly is bad, the reliability of relay work is reduced.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is to provide a kind of relay mounting structure that can avoid the incorporate bolt and nut of use of above-mentioned deficiency.
The purpose of this utility model is achieved in that railway signal relay is made up of base, magnetic circuit assembly and contact unit, the magnetic circuit assembly is fixed on the base by the cooperation of iron core screw bolt and nut, it is characterized in that: with the screw rod of integrated bolt and nut, by the location hole on the base, the magnetic circuit assembly is located, can prevent that the magnetic circuit assembly is loosening, screw cooperates with the nut of integrated bolt and nut type covered and is fixed on the base.
Said incorporate bolt and nut is that the end at screw rod is a nut, and the two is an one, and the diameter of screw rod is greater than the internal diameter of nut.
The utility model is compared with the prior art scheme, has the following advantages:
1, used integrated bolt and nut, and the diameter of screw rod has changed the phenomenon that cooperates three nuts on a bolt greater than the diameter of nut, can not become flexible when fastening, the assembling fastness of magnetic circuit and base strengthens, and the reliability when relay is used improves greatly.
2, owing to increased anchor point, can stop magnetic circuit assembly and base assembling back to produce loosening effectively in the both sides of iron core bolt.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of integrated bolt and nut.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, said incorporate bolt and nut is that the end at screw rod 2 is a nut 1, and the two is an one, and the diameter of screw rod is M5, and the internal diameter of nut is M3.Because the torsion of the two generation is inequality, can be when fastening postorder nut, firm good integrated bolt and nut is loosening.
Referring to Fig. 2, railway signal relay is made up of base 5, magnetic circuit assembly 3 and contact unit 10, the magnetic circuit assembly is fixed on the base by iron core bolt 4 and nut 7 cooperations, screw rod with integrated bolt and nut 9, by the location hole on the base, with magnetic circuit assembly location, can prevent that the magnetic circuit assembly is loosening, screw 6 cooperates with the nut of integrated bolt and nut and type is covered 8 is fixed on the base.
Claims (2)
1, a kind of relay mounting structure that uses incorporate bolt and nut, form by base, magnetic circuit assembly and contact unit, the magnetic circuit assembly is fixed on the base by the cooperation of iron core screw bolt and nut, it is characterized in that: with the screw rod of integrated bolt and nut, by the location hole on the base, with magnetic circuit assembly location, screw cooperates with the nut of integrated bolt and nut type covered and is fixed on the base.
2, according to the described railway signal relay of claim 1, it is characterized in that: said incorporate bolt and nut is a nut for the end at screw rod, and the two is an one, and the diameter of screw rod is greater than the internal diameter of nut.
