Description

Technical Field

[0001] The utility model relates to the technical field of railway signal equipment, in particular to a railway signal relay protection device. Background Art

[0002] The existing railway signal relay is mainly composed of an electromagnetic system, a contact system, a protective cover and a base. The protective cover and the base are fixed with symmetrical bolts at four corners to form the protection mechanism of the relay. The relay is horizontally inserted into the relay socket of the combination cabinet through the metal copper sheet in the base.

[0003] In this structure, when tightening the protective cover fixing bolts, torque is transmitted to the contact group, which will cause changes in technical indicators such as contact pressure and contact gap, resulting in changes in the mechanical and electrical characteristics of the relay, and even unstable characteristics. Patent CN221125817U discloses "A railway signal relay housing protection structure." Although it solves the problem of torque transmission between the relay contact group and the base, its structure and installation method make the relay subject to gravity. Over time, looseness or tilting will occur between the base and the socket, which will also cause changes and instability in the electrical characteristics.

[0004] Therefore, there is an urgent need for a railway signal relay protection device with a stable connection between the relay base and the socket. Summary of the Invention

[0005] The purpose of the utility model is to provide a railway signal relay protection device, so as to at least solve the problem of unstable connection between the relay base and the socket in the prior art.

The base and the outer cover are fixed to the socket by a second fixing component. The second fixing component passes through the outer cover and the base in sequence and is fixedly connected to the socket.

[0008] Furthermore, the base is a rectangular parallelepiped, and short sides are symmetrically extended outward on both sides of the opening end of the outer cover, and the outermost ends of the short sides are flush with the upper and lower end surfaces of the base.

[0009] Furthermore, the base and the outer cover are in a convex shape as a whole.

[0014] Furthermore, the second fixing assembly includes a second bolt and a third bolt, the third bolt is fixed to the socket, and the second bolt passes through the second opening and the through hole in sequence and is fixedly connected to the third bolt.

[0015] Furthermore, an internal thread is provided inside the nut of the third bolt.

[0016] Furthermore, a handle is provided on the side wall of the outer cover away from the base.

[0029] Example:

[0030] like Figure 1 As shown, this embodiment provides a railway signal relay protection device, including a base 1 and an outer cover 2. The base 1 is a rectangular parallelepiped, and one end of the outer cover 2 is set to be open. The upper and lower sides of the open end of the outer cover 2 extend symmetrically outward, and the outermost ends of the short sides are flush with the upper and lower end surfaces of the base 1. The base 1 and the outer cover 2 are generally convex, and the relay is arranged in the outer cover 2.

[0031] Furthermore, the open end of the outer cover 2 is fixed to the side wall of the base 1 through a first fixing component, and the first fixing component is provided on both sides of the outer cover 2 .

[0032] Two first openings are respectively formed on the short sides of the outer cover 2. The two first openings on the same short side are symmetrically distributed near the left and right ends of the short side. The first openings on the two short sides are symmetrically arranged.

[0033] The first fixing assembly includes four first bolts 4 and four nuts. The four nuts are respectively embedded in the four corners of the side wall of the base 1, and the four nuts respectively correspond to the four first openings on the outer cover 2. The first bolts 4 pass through the first openings and are screwed into the nuts to fix the outer cover 2 on the base 1.

[0034] Furthermore, the base 1 and the outer cover 2 are fixed to the socket via a second fixing assembly, and the second fixing assembly passes through the outer cover 2 and the base 1 in sequence and is fixedly connected to the socket.

[0035] A second opening is provided between the two first openings on the upper short side of the outer cover 2 , and a through hole is provided at a position on the side wall of the base 1 close to the upper end and corresponding to the second opening.

[0036] The second opening is consistent in size with the through hole.

[0037] like Figure 2 and Figure 3 As shown, the second fixing assembly includes a second bolt 5 and a third bolt 6. The third bolt 6 is fixed to the socket and is used to fix the socket to the combination cabinet. The nut 601 of the third bolt 6 is provided with an internal thread 602. The second bolt 5 passes through the second opening and the through hole in turn and is screwed into the internal thread 602 of the third bolt 6 to fix it, thereby fixing the base 1 and the outer cover 2 to the socket.

[0038] The second bolt 5 passes through the outer cover 2 and the base 1 in sequence and is fixed to the third bolt 6 of the socket, thereby fixing the outer cover 2 and the base 1 to the socket. After the relay is installed in the relay socket, the influence of the relay's own gravity can be offset, ensuring that there will be no loosening or tilting between the base and the socket after the relay is installed, thereby ensuring the stability of the mechanical and electrical characteristics between the relay and the relay socket.

[0039] Furthermore, in order to facilitate the removal and installation of the outer cover 2 and the base 1, a handle 3 is provided on the side wall of the outer cover 2 away from the base 1, and a third opening for installing the handle 3 is symmetrically opened on the side wall of the outer cover 2. The handle 3 is an elastic structure, and the elasticity can ensure that it is in a clamped state after being installed on the outer cover 2 and will not fall off.

[0040] In this embodiment, the fixing bolt on the relay socket is replaced with a third bolt 6 having an internal thread 602 inside the nut 601. The second bolt 5 passes through the outer cover 2 and the base 1 in sequence and is fixedly connected to the third bolt 6, thereby fixing the outer cover 2 and the base 1 to the socket. This ensures that the relay base 1 and the socket are not loosened or tilted due to gravity, making the connection between the base 1 and the socket stable, thereby effectively ensuring the stability of the electrical characteristics of the relay. At the same time, in this embodiment, only the fixing bolts of the relay socket need to be replaced, and the relay socket does not need to be replaced. Therefore, this embodiment is suitable for both new construction projects and existing renovation projects.

[0041] The installation method of this embodiment is as follows:

[0042] When this embodiment is used for renovation of an existing project, the existing fixing bolts on the relay socket are first replaced with the third bolts 6, without removing the internal wiring of the socket. Then, the new relay cover 2 is fixed to the base 1 by the first bolts 4, and then the cover 2 and the base 1 are fixed to the third bolts 6 of the socket by the second bolts 5, and the installation is completed.

[0043] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
