Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of relays, and specifically relates to a protective structure for the shell of a railway signal relay. Background Art
[0002] A railway signal relay refers to a special electromagnetic switch device in various railway signal devices or systems. It consists of an electromagnetic coil, a contact group, a transmission system, and components that ensure the closure or disconnection of the contacts. The main types include: DC non-polar relays, polarized relays, polarity-retaining relays, etc. In the railway operating environment, it may face various accidental impacts, such as tool drops, cargo collisions, etc. A strong shell protection structure can effectively resist these impacts and protect the internal relay components from damage.
[0003] The patent document with the prior art publication number CN221125817U provides a protective structure for the shell of a railway signal relay, which is characterized by including: a base, an outer cover, a handle, an insertion plate, an inlaid nut, and a screw; 4 inlaid nuts are symmetrically arranged at the four corners of the base; there is a rabbet on the upper end surface of the base, and 4 counterbore holes are symmetrically arranged on the outer sides of the four corners of the outer cover; the depth of the inner end surface of the four corners of the outer cover is less than the height of the rabbet of the base. This protective structure for the shell of a railway signal relay is used to ensure that before and after installing the outer cover of the relay, the relay technical indicators such as the contact pressure and contact gap of the relay do not change, thereby effectively ensuring the stability of the mechanical and electrical characteristics of the relay.
[0004] However, during the use of existing railway signal relays, since railway signal relays are usually installed outdoors or in harsh environments, they are faced with the erosion of rain, dust, and moisture. Due to the poor waterproof and dustproof effects of the protective structure of the railway signal relay shell, and rain, dust, and moisture are easily introduced into the protective structure, resulting in the rusting and corrosion of the internal components of the relay, thus affecting its performance and service life.
[0005] Therefore, those skilled in the art have proposed a protective structure for the shell of a railway signal relay to solve the problems raised in the background art. Summary of the Utility Model
[0006] In order to solve the above technical problems, the utility model provides a protective structure for the shell of a railway signal relay to solve the problems in the prior art that the waterproof and dustproof effects of the protective structure of the railway signal relay shell are poor, and rain, dust, and moisture are easily introduced into the protective structure, resulting in the rusting and corrosion of the internal components of the relay, thus affecting its performance and service life.
[0007] A protective structure for the housing of a railway signal relay, comprising an installation unit and a protection unit. Among them, the installation unit includes a base, and a docking frame is fixedly connected to the center of the top of the base. A first gasket is fixedly connected to the top of the docking frame, and a second gasket is movably connected to the outside of the docking frame. An installation groove is formed inside the installation unit;
[0008] The protection unit includes a protective cover fixedly connected to the outer surface of the docking frame. An installation seat is fixedly connected to the outside of the protective cover, and a fixing screw is threadedly connected through the top of the installation seat. A protection groove is formed inside the protection unit, and a clamping plate is fixedly connected to the inner wall of the protection groove.
[0009] Preferably, clamping grooves are formed above the outside of the docking frame away from the second gasket. There are eight clamping grooves, and the eight clamping grooves are arranged in pairs symmetrically.
[0010] Preferably, both the first gasket and the second gasket are made of rubber material, and both the first gasket and the second gasket are solid structures.
[0011] Preferably, the base and the docking frame are of an integral structure, and the outer surfaces of the base and the docking frame are smooth.
[0012] Preferably, a handle frame is fixedly connected to the top of the protective cover, and a handle rod is movably connected to the outside of the handle frame.
[0013] Preferably, the protective cover is made of plastic material, and the protective cover is of a transparent structure.
[0014] Compared with the prior art, the present utility model has the following beneficial effects:
[0015] 1. By setting the docking frame, the first gasket and the second gasket, when using the protective structure for the housing of the railway signal relay, the staff installs the components of the relay in the installation groove of the base. After installation, the staff docks the protection groove of the protective cover on the docking frame. At this time, the clamping plate will enter the clamping groove, thus playing a role in clamping and fixing. At the same time, the bottom of the protective cover will press against the second gasket to form a first sealing structure, and the first gasket on the docking frame will press against the inner wall of the protective cover to form a second sealing structure. Then, it can be fixed with fixing screws. In this way, the waterproof and dustproof effect of the protective structure for the housing of the railway signal relay is improved, and it is avoided that rainwater, dust and moisture enter the protective structure, resulting in rust and corrosion of the internal components of the relay. Therefore, the performance and service life of the railway signal relay are guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS
