[0030] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0031] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0032] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0033] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0034] It should be noted that the terms "distal" and "proximal" are used as directional terms, which are commonly used in the field of interventional medical devices. "Distal" refers to the end furthest from the operator during the procedure, while "proximal" refers to the end closest to the operator. Axial direction refers to the direction parallel to the line connecting the center of the distal and proximal ends of the medical device; radial direction refers to the direction perpendicular to the aforementioned axial direction.

[0035] Figure 1 This is a schematic diagram of the bolt anti-loosening device of this utility model installed on a turnout pad.

Figure 1 and Figure 2 As shown, the bolt anti-loosening device 100 of this utility model is adapted to the turnout pad plate. Due to the narrow space at the tip of the switch rail 500 of the turnout switch, the setting of the turnout sleeper bolt 121 is limited. According to the space requirements, it is set at the position of the slide plate and sunk on the surface of the slide plate. In order to prevent it from loosening and protruding from the surface of the slide plate, affecting the switching of the switch rail 500, the turnout sleeper bolt anti-loosening device 100 needs to be set.

[0036] The bolt anti-loosening device 100 provided by this utility model is adapted to the turnout pad plate. The turnout sleeper bolt 121 is made of polyethylene nut sleeve. The nut sleeve, turnout sleeper bolt 121 and slide plate 400 are connected by cotter pin 123 to prevent the turnout sleeper bolt 121 from loosening and falling out above the surface of slide plate 400.

[0037] The existing nut sleeve only has a hole in one direction for the cotter pin 123 to pass through, which is inconvenient for the cotter pin 123 to pass through. Because the nut sleeve is embedded in the slide plate 400, it is difficult to remove the nut sleeve, which is inconvenient for disassembling the turnout sleeper bolt 121. Therefore, this utility model provides a bolt anti-loosening device 100 adapted to the turnout pad plate.
