[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the term "provided with" that may appear should be understood in a broad sense. For example, the object "provided with" may be a part of the body, or may be arranged separately from the body and connected to the body, and the connection may be a detachable connection or an inseparable connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] The present invention is further described in detail below in conjunction with the embodiments.

[0025] The specific embodiment of the elastic sliding bed bottom plate provided by the utility model is as follows:

[0026] See also Figure 1-5 The elastic slide bed bottom plate includes a base plate 1, two pressure tongues 2 and a guide iron 3; the base plate 1, the pressure tongue 2 and the guide iron 3 are all machined steel structures. The base plate 1 is a flat steel structure, the pressure tongue 2 is a strip steel structure with a U-shaped cross section, and the guide iron 3 is a block steel structure with a right-angle trapezoidal cross section.

[0027] Bolt holes 102 are provided at both ends of the base plate 1. The bolt holes 102 are used to fix the base plate with bolts when the elastic slide bed plate is installed on the track.

[0028] The advantages of machining are fast production and processing speed, flexible size, and good controllability of overall quality and surface quality.

[0029] The two pressing tongues 2 are symmetrically connected to both sides of the base plate 1 by welding, and the U-shaped openings of the two pressing tongues 2 are opposite to each other. The pressing tongues 2 are used for connecting and limiting the elastic slide bed plate and the lower part of the pressing tongue 2 corresponds to the base plate 1 during welding; the guide iron 3 is connected to the upper side of the base plate 1 by welding, the plane of the guide iron 3 is connected to the base plate 1, and the upper side surface of the guide iron 3 is an inclined surface.

[0030] Machining and welding connections are fast and efficient. Compared with the cast elastic slide bed bottom plate, the production efficiency can be significantly improved and the labor cost required for a single finished product can be reduced.

[0031] Grooves 101 cooperating with the tongue 2 are symmetrically provided on both sides of the substrate 1. The grooves 101 are used to limit the tongue 2 when welding the tongue 2 to ensure the accurate position of the tongue 2. In some other embodiments, the length of the groove 101 may be the same as the length of the tongue 2. In this embodiment, the length of the groove 101 is less than the length of the tongue 2, and a notch 202 is provided at the lower part of one end of the tongue 2. The notch 202 is used to fit with the outer side of the side wall of one end of the groove 101, and the depth of the notch 202 is less than the depth of the groove 101, so that there is a gap between the lower part of the tongue 2 and the bottom of the groove 101, that is, there is a gap between the welding connection surfaces of the substrate 1 and the tongue 2; the gap ensures that the root of the weld can be penetrated, so that the welding connection between the tongue 2 and the substrate 1 is more firm.

[0032] In this embodiment, a welding groove 201 is provided at the connection between the tongue 2 and the substrate 1, and the welding groove 201 can improve the strength and durability of welding, ensure welding quality and sealing, reduce welding stress, reduce deformation and cracking risks, ensure the cleanness of the joint surface, reduce welding defects, and improve welding quality. In some embodiments, a groove is also provided at the connection between the guide iron 3 and the substrate 1 to improve welding quality.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
