Description

Technical Field

[0001] The utility model relates to the technical field of a connecting structure of a track model, in particular to a swing arm type coupler of a simulation track model. Background Art

[0002] Track model is a technology that restores real rail transit vehicles in a certain proportion. Due to the small size of the track model and the limited placement space, it is impossible to completely restore the use scenario of the large turning radius of the real rail transit vehicle. Therefore, the vehicle in the track model needs to pass through a smaller diameter curve. One of the final factors that affect the vehicle passing through the curve is the coupler connecting the two adjacent carriages. The coupler of the traditional rail transit model adopts a handshake connection coupler with a fixed rotation center. When the vehicle passes through a small radius track, the handshake connection coupler is prone to decoupling due to insufficient steering angle of the coupler, which is inconvenient.

[0003] Based on the above, the utility model proposes a swing-arm type coupler of a simulated track model. Utility Model Content

[0022] 1. In this solution, when the train model turns on the arc section of the track, the two limit grooves, two limit posts and the tension spring cooperate to enable the sway seat to swing toward the inner circle of the turn. At this time, the sway seat deflects with the limit post close to the inner circle of the turn as the center line of the limit post.

[0033] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0034] Embodiment 1

[0036] It should be noted that a set of connection units are respectively provided at both ends of each set of carriage chassis 1. In the following description, the end of the carriage chassis 1 refers to the end closest to the connection unit, and the connection unit is explained with reference to this end:

[0037] Reference Figure 3An assembly hole 2 is provided on the carriage chassis 1 in the vertical direction, and the assembly hole 2 is close to the end of the carriage chassis 1. A limiting column 3 is vertically extended from the upper end surface of the carriage chassis 1. Two groups of limiting columns 3 are provided and are respectively located on both sides of the assembly hole 2 along the length direction of the carriage chassis 1. A holder 4 is also provided on the upper end surface of the carriage chassis 1, and the holder 4 is located on the side of the assembly hole 2 away from the end of the carriage chassis 1.

[0038] Reference Figure 2 and Figure 4 The connecting unit includes a deflection seat 5 located on the upper end surface of the vehicle chassis 1, and the deflection seat 5 is in a horizontally arranged butterfly shape.

[0039] A limit groove 6 is respectively provided on the two side surfaces of the sway seat 5 along the width direction of the car chassis 1. The limit groove 6 penetrates to the upper and lower end surfaces of the sway seat 5 and the two groups of limit columns 3 are respectively located in the two limit grooves 6 when the hook 15 is returned to the center. The limit groove 6 is in the shape of a semi-arc groove and the two ends of the limit groove 6 along the arc length direction are chamfered.

[0040] A limiting tail hook 7 is respectively extended from two side surfaces of the deflection seat 5 along the width direction of the chassis 1 , and the limiting tail hook 7 is located on a side of the limiting groove 6 away from the end of the chassis 1 .

This is the James-type coupler technology in the prior art, so it will not be described in detail.

[0043] The limiting column 3 is made of plastic, and can form a fixed motion curve with the limiting groove 6 and the limiting tail hook 7 on the deflection seat 5, or in other words, the motion curve of the outer part of the limiting column 3 and the deflection seat 5 along the width direction of the chassis 1 is fixed. Figure 2 and Figure 6 The sway seat 5 can sway in a non-fixed circle along a fixed line on both sides of the car chassis 1 along the length direction, that is, when the train model turns at the arc section of the track, the sway seat 5 can sway toward the inner circle of the turn. At this time, the sway seat 5 deflects with the limit column 3 close to the inner circle of the turn as the rotation axis until the limit column 3 on the other side slides into its corresponding limit tail hook 7.
