Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of connecting plates for the side frames of bullet trains, and particularly relates to a connecting plate for the side frames of bullet trains. Background Art
[0002] A bullet train, the full name of which is a powered vehicle, refers to a vehicle equipped with a power device in a rail transit system, including two categories: locomotives and powered carriages. A bullet train is equipped with driving wheels, and correspondingly, a vehicle without a driving device is a trailer. During the installation process of the side frames of bullet trains, connecting plates are used for fixation;
[0003] There is a connecting plate for the gap between the side roof plates of a bullet train with the application number CN202021882922.7. Among them, it is connected to the reserved card holes on the side roof plate through buckles, which is convenient for installing the connecting plate at the splicing position of two side roof plates. Then, it is connected to the reserved screw holes on the side roof plate through fastening bolts, realizing the fixation of the connecting plate between two side roof plates, improving the installation stability, being able to connect and fix two adjacent side roof plates, avoiding the generation of gaps, not having the phenomenon of dust accumulation in the gaps, being able to improve the sanitary environment inside the carriage, and facilitating the subsequent cleaning work inside the carriage;
[0004] However, the fastening bolt passes through the buckle and is connected to the reserved screw hole on the side roof plate of the bullet train. Once the installation position needs to be adjusted between the buckle and the roof plate of the bullet train, since the position of the reserved hole is fixed, it is easy to cause the fastening bolt to be unable to pass through the buckle and be connected to the reserved screw hole on the side roof plate of the bullet train, and the overall length of the connecting plate cannot be adjusted, resulting in a reduced installation range and reduced practicality.
[0005] Therefore, this application provides a connecting plate for the side frames of bullet trains to meet the requirements. Content of the Utility Model
[0006] The purpose of the utility model is to solve the problems existing in the above background art, and to propose a connecting plate for the side frames of bullet trains.
[0007] The technical problem to be solved by the utility model is to provide a connecting plate for the side frames of bullet trains to solve the problems that the size of the existing connecting plate for the side frames of bullet trains cannot be adjusted and the fixing holes are not easy to adjust.
[0008] To solve the above technical problems, the utility model provides the following technical solutions:
[0009] A connecting plate for the side frames of bullet trains, comprising: a first connecting plate, a second connecting plate is arranged on the front surface of the first connecting plate, a first slider is fixedly connected to the middle of the rear end of the second connecting plate, the side of the first slider away from the second connecting plate is embedded in the front surface of the first connecting plate, and bidirectional bolts are fixedly connected to both sides of the front surface of the first connecting plate and the left and right sides of the rear end of the second connecting plate through threads.
[0010] Preferably, chutes are provided around the tops of the first connecting plate and the second connecting plate. A second slider is slidably connected inside the chutes, and fixing holes are provided at the tops of the second sliders.
[0011] Preferably, limiting holes are provided on both the left and right sides of the top of the first connecting plate at equal longitudinal intervals. Limiting blocks are embedded on both the left and right sides of the top of the second slider. Springs are fixedly connected between the limiting blocks and the second slider, and the limiting blocks are arranged to match the limiting holes.
[0012] Preferably, the cross-section of the limiting block is frustum-shaped.
[0013] Preferably, moisture-proof boards are embedded in the middle of the tops of the first connecting plate and the second connecting plate.
[0014] Compared with the prior art, the present utility model has at least the following beneficial effects:
[0015] In the above solution, by setting the second slider, when it is necessary to adjust the position of the fixing hole and the installation area, the user can press the limiting block downward and contract it into the second slider by inserting a finger into the limiting hole, so that the slider can slide through the chute to a suitable position. After the limiting block is not squeezed, it will be snapped into the limiting hole upward by the elastic force of the spring, so as to quickly fix the second slider and the chute, thus facilitating the installation by the user.
[0016] In the above solution, by setting the bidirectional bolt, when it is necessary to adjust the overall size of this connecting plate, the user can use an external tool to turn the bidirectional bolt, and drive the first connecting plate and the second connecting plate to move towards each other or in the opposite direction through the thread, so as to adjust the overall size of this connecting plate, thus facilitating the installation according to the user's needs.

[0026] As Figure 1 、 Figure 2 and Figure 3 shown, an embodiment of the present invention provides a connecting plate for the side frame of a bullet train, including: a first connecting plate 1, a second connecting plate 101 is disposed on the front surface of the first connecting plate 1, a first slider 104 is fixedly connected to the middle of the rear end of the second connecting plate 101, and one side of the first slider 104 away from the second connecting plate 101 is embedded in the front surface of the first connecting plate 1. Bi-directional bolts 103 are fixedly connected to both sides of the front surface of the first connecting plate 1 and the left and right sides of the rear end of the second connecting plate 101 by threads;
[0027] When the user needs to adjust the overall size of this connecting plate, the user can rotate two bidirectional bolts 103 through an external tool, so that the bidirectional bolts 103 drive the first connecting plate 1 and the second connecting plate 101 to move towards each other or in the opposite direction through the threads, so as to adjust the overall size of this connecting plate.
[0028] In this embodiment, as Figures 2 - 3 shown;
[0029] Chutes 2 are provided around the top ends of the first connecting plate 1 and the second connecting plate 101. A second slider 201 is slidably connected inside the chutes 2, and a fixing hole 202 is provided at the top end of the second slider 201;
[0030] When there is a deviation in the position of the installation holes of this mounting plate, the fixing hole 202 can slide along the chute 2 through the second slider 201, so as to adjust the position of the fixing hole 202 and the fixing area, so as to facilitate installation;
[0031] Limiting holes 3 arranged longitudinally at equal distances are provided on the left and right sides of the top end of the first connecting plate 1 inside the chute 2.
