[0006] The utility model has the advantages that the general steel rail fixed fishplate can adapt to steel rails with different bolt hole positions by setting the sliding slot, the pressing plate and the tooth groove, reduces the demand for customized fishplates, has strong universality, saves time and labor cost, improves the efficiency of railway track construction and maintenance, significantly shortens the installation period, avoids additional costs caused by customized non-standard fishplates, and reduces the cost.

[0007] On the basis of the above technical scheme, the utility model can be further improved as follows.

[0008] Further, the pressing plate is provided with a plurality of thread holes corresponding to a plurality of bolt hole positions of a single track.

[0009] The above further beneficial effects are that the multi-hole connection is stable and has high strength.

[0010] Further, a plurality of thread holes have a plurality of different hole spacings.

[0011] The above further beneficial effects are that on the basis of adapting to steel rails with different bolt hole positions, different bolt hole spacings can also be adapted. BRIEF DESCRIPTION OF DRAWINGS

[0017] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not to limit the scope of the utility model.

[0018] Example 1

[0019] As shown in Figure 1 and Figure 2 , a general steel rail fixed fish tail plate includes a fish tail plate body 2, a sliding groove 22 is formed in the middle of the fish tail plate body 2, and tooth grooves 21 are provided on the upper and lower sides of the sliding groove 22 on the outer side of the fish tail plate body 2; it also includes a pressing plate 3 and a fixed bolt 4, one side of the pressing plate 3 is toothed so that the pressing plate 3 can engage with the tooth groove 21, and the fixed bolt 4 is used to pass through the threaded hole 31 in the middle of the pressing plate 3, the sliding groove 22, and the bolt hole position 5 on the steel rail 1 in sequence and is screwed with the bolt hole position 5.

[0020] When the steel rail 1 with non-standard bolt hole position is connected, the fish tail plate body 2 is placed outside the connection between the two steel rails 1, the position of the pressing plate 3 on the tooth groove 21 is adjusted according to the bolt hole position 5 of the steel rail 1, the threaded hole 31 of the pressing plate 3 is aligned with the bolt hole position 5 of the steel rail 1, the fixed bolt 4 is inserted from the pressing plate 3, and the pressing plate 3, the fish tail plate body 2 and the steel rail 1 are fixed in sequence; the general steel rail fixed fish tail plate can adapt to steel rails 1 with different bolt hole positions 5 by setting the sliding groove 22, the pressing plate 3 and the tooth groove 21, reducing the need for customized fish tail plates, and having strong universality; time and labor costs are saved, the efficiency of railway track construction and maintenance is improved, the installation period is significantly shortened; additional costs caused by customized non-standard fish tail plates are avoided, and costs are reduced.

[0021] Example 2

[0022] As shown in Figure 1As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0023] The pressure plate 3 has multiple threaded holes 31 corresponding to the multiple bolt holes 5 of a single track 1. The multi-hole connection is stable and has high strength.

[0024] Example 3

[0025] like Figure 2 As shown, this embodiment is a further improvement on embodiment 2, as detailed below:

[0026] There are various hole spacings between multiple threaded holes 31. This further improves the compatibility of the universal rail fixing fishplate with rails 1 with different bolt hole positions.
