Problems solved by technology
[0004] However, due to different external working conditions, the primary and secondary anti-jump mechanisms may fail during the operation of the vehicle. In this case, the beating of the lower lock pin mechanism will push the hook lock to move upward to the unlocked position. Causes the coupler to unlock naturally and the knuckle to open, causing the train to separate

Embodiment Construction
[0036] On the basis of the basic structure of the existing coupler, the present invention provides a latch used in conjunction with the coupler to further restrict the hook lock from moving up to the unlock position, avoid abnormal unhooking phenomenon, and ensure that the coupler is in a reliable locked state.
[0037] Hereinafter, this embodiment will be described in detail with reference to the drawings in the specification.
[0038] See figure 2 , This figure is the front view of the plug described in this embodiment.
[0039] Such as figure 2 As shown, the first pole section 1 is a straight pole, and the second pole section 2 has a curved portion 21 in the middle. Along the length direction, the first pole section 1 and the second pole section 2 are arranged in parallel and one side ends of the two are connected, which is roughly in the shape of a clip. A receiving portion 4 is formed between the curved portion 21 of the second rod section 2 and the first rod section 1.

The invention discloses a bolt for matching a coupler in a locking state to use. The bolt comprises a first rod section and a second rod section, wherein the first rod section is a straight rod; the middle part of the second rod section is provided with a bending part; the first rod section and the second rod section are arranged in parallel along the length direction, and a lateral end part of the first rod section and the lateral end part of the second rod section are connected; and an accommodating part is formed between the bending part of the second rod section and the first rod section.On the basis of the bolt, the invention also discloses a coupler provided with the bolt, and a lower lock pin or a lower lock pin body of the coupler is provided with a bolt mounting hole. The first rod section of the bolt is inserted in the bolt mounting hole of the lower lock pin or the lower lock pin body, and the lower lock pin or the lower lock pin body below the bolt installation hole is arranged in the accommodating part of the bolt. When two bounce prevention mechanisms of the coupler both fail, the straight rod section of the bolt is contacted with a lower lock cavity stud of the coupler body to prevent a lower lock pin mechanism from continuing to move upward, and further prevent lock iron from continuing to move to an upper lock cavity, so that the bounce prevention performanceof the coupler is further strengthened.
Description
Technical field [0001] The invention relates to a rail car connection technology, in particular to a bolt and a coupler with the bolt. Background technique [0002] The coupler is one of the important parts of railway vehicles. Its main function is to ensure the connection between vehicles and realize the operation of train marshalling and traction vehicles. During the operation of freight cars, due to the abnormal opening of the coupler, accidents such as train separation and abnormal parking will be caused, which will seriously affect the normal transportation order of the railway. Therefore, in order to improve the efficiency and safety of railway transportation, prevent the abnormal opening of the coupler. The hook is especially important. At present, the anti-coupling separation of railway freight cars is mainly realized by the anti-jumping mechanism of the lower lock pin and the anti-jumping mechanism of the lower lock pin rod (body) of the coupler itself. Figure 1a Shows ...
