Abstract

The utility model relates to a self-locking hook typed safe relay which has the advantages of convenient installation and fixation, simple structure and being suitable for field application. The utility model comprises a relay, a self-locking hook and a socket, and wherein, the self-locking hook is arranged in the inside or the outside of the socket by bolts, and the hook of the self-locking hook hangs on a shell of the relay and is milled with a platform. The utility model is especially suitable for the application of an installation typed relay used in railways.

Description

Self-locking coupling type safety type relay

Technical field:

The utility model relates to railway equipment technical field, and exactly it is a kind of self-locking coupling type safety type relay.

Background technology:

Safety type relay is the important equipment of railways train operation, and operation principle and mounting means are different from the relay of other type, and the quality of its operating state directly affects the safety of railways train operation.For guaranteeing the safety type relay reliably working, between relay and socket, use special metal extension spring (as Fig. 1) or plate (as Fig. 2) to fix usually.The shortcoming of this dual mode is: the former is owing to the operational environment vibrations are big, and is loosening easily, and relay is come off, and extension spring production technology is complicated, the production cost height, and the latter installs inconvenience, is unfavorable for on-the-spot the use especially.China Patent No.: 96230714 disclose the utility model patent that a kind of name is called " relay of integrative-structure ", China Patent No.: 99226129 disclose the utility model patent that a kind of name is called " relay socket of improvement ".The goal of the invention of above-mentioned two patents also is the convenience that installs and fixes for relay, but the safety type relay that its structure is not suitable for using in the railway adopts.

Summary of the invention:

The purpose of this utility model provides a kind of self-locking coupling type safety type relay, and it has the convenience of installing and fixing, and is simple in structure, is fit to the on-the-spot characteristics of using.It comprises relay, from locking and hanging hook and socket, it is characterized in that: be installed in socket (3) inboard or the outside from locking and hanging hook (2) with bolt (5), hang on the housing of relay (1) from the hook of locking and hanging hook (2).The hook place is milled with platform (6) on the housing of relay (1).The hook place can have groove (7) on the housing of relay (1).

The utility model has the advantages that: easy to use, safe and reliable, appearance is neat, attractive in appearance, has reduced the parts kind, has reduced production cost, and can be as required installs from locking and hanging hook at both direction up and down.

Description of drawings:

Fig. 1 hangs the fixing structural representation of spring for existing safety type relay uses metal.

Fig. 2 uses the fixing structural representation of plate for existing safety type relay.

Fig. 3 is a structural representation of the present utility model.

The structural representation of Fig. 4 when to be the utility model use on existing plate fixation type safety type relay.

Embodiment:

Embodiment 1:

The structure of the utility model repeat circuit 1 does not change, just changed the fixed form between relay 1 and the socket 3, be milled with platform 6 on the shell of relay 1, step is used for hanging from locking and hanging hook 2, during use, socket 3 is fixed on the mounting panel 4, relay 1 is contained on the socket 3, use from locking and hanging hook 2 and hang the jail.The socket outside can be contained in from locking and hanging hook 2 as required, also the socket inboard can be contained in.

Embodiment 2:

For the fixing mount type relay 1 of existing plate, can will hang over from locking and hanging hook 2 on the groove that plate is installed (seeing accompanying drawing 4).
