Technical Field
[0001] The utility model relates to the technical field of gooseneck skeleton vehicles, and specifically, to a new front positioning rotary lock seat for a gooseneck skeleton vehicle. Background Art
[0002] When a gooseneck skeleton vehicle is matched with a gooseneck body, since the front part area of the gooseneck body is a gooseneck groove structure, the corner fitting positions of the gooseneck skeleton vehicle here need to be designed according to the drop of this gooseneck groove structure. Among them, the existing front positioning rotary lock seat for locking and connecting with the front corner fitting of the gooseneck body through a locking mechanism is assembled and welded by multiple components, with low self-strength and complex manufacturing. Moreover, when the existing front positioning rotary lock seat is welded on the front sealing frame, it is necessary to additionally weld a reinforcing plate at the contact part between the front positioning rotary lock seat and the front sealing frame to improve the connection strength between the front positioning rotary lock seat and the front sealing frame. This will cause stress concentration, large welding amount, increase the processing process and welding time, be time-consuming and laborious, and have high labor costs.
[0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Summary of the Invention
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide a new front positioning rotary lock seat for a gooseneck skeleton vehicle. The front positioning rotary lock seat of the utility model is an integrally formed component with high self-strength, without the need to additionally weld a reinforcing plate, greatly reducing the welding amount, reducing the processing process and welding time, saving time and effort, and having low labor costs.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a new front positioning rotary lock seat for a gooseneck skeleton vehicle, which is respectively arranged on the rear side surfaces of the left and right end parts of the front sealing frame. The two new front positioning rotary lock seats for gooseneck skeleton vehicles have the same structure and are symmetric left and right. The left new front positioning rotary lock seat for a gooseneck skeleton vehicle includes a lock seat body. The lock seat body is a U-shaped groove plate structure integrally die-cast and open at the lower, front and rear sides. The front side edge of the upper side plate of the lock seat body is also integrally die-cast with a vertical plate bent upwards. The vertical plate is attached to and welded with the rear side surface of the front sealing frame. The lower side parts of the front side edges of the left side plate and the right side plate of the lock seat body are both integrally formed with vertical ribs extending forward and located below the front sealing frame. The upper side edges of the vertical ribs are attached to and welded with the lower side surface of the front sealing frame. A lock head pin hole for locking and connecting with the left front corner fitting of the gooseneck body is punched on the upper side plate of the lock seat body. A U-shaped groove with an open upper side is punched on the vertical plate. The U-shaped groove corresponds to the positioning hole on the front sealing frame for installing the front positioning device before and after.
[0006] Based on the above, an inner reinforcing plate is welded at the front side part between the left side plate and the right side plate of the lock seat body.
[0007] Based on the above, there are arc transitions and integrally formed connections between the left side edge of the upper side plate of the lock seat body and the upper side edge of the left side plate, and between the right side edge of the upper side plate of the lock seat body and the upper side edge of the right side plate.
[0008] Based on the above, the lower rear parts of the left side plate and the right side plate of the lock seat body are both provided with bevel edges that are lower in the front and higher in the rear.
[0009] Based on the above, the vertical plate is a trapezoidal plate, with the upper side edge of the vertical plate as the upper base and the lower side edge of the vertical plate as the lower base.
[0010] The front positioning rotary lock seat of the present utility model has substantial features and progress compared with the prior art. Specifically, the front positioning rotary lock seat of the present utility model is an integrally die-cast component, with higher self-strength and simple production. The front side edge of the upper side plate of the lock seat body is integrally die-cast with a vertical plate that bends upward. The vertical plate is attached to and welded to the rear side surface of the front sealing frame, increasing the welding contact area between the front positioning rotary lock seat and the front sealing frame. Moreover, the lower side parts of the front side edges of the left side plate and the right side plate of the lock seat body are integrally formed with vertical ribs. The vertical ribs support the bottom of the front sealing frame and are welded to the front sealing frame, effectively improving the overall connection strength between the front positioning rotary lock seat and the front sealing frame. There is no need to weld any reinforcement plates at the contact part between the front positioning rotary lock seat and the front sealing frame, which can meet the locking requirements of the front corner parts of the gooseneck box body and the gooseneck frame vehicle when the gooseneck box body is matched with the gooseneck frame vehicle. It effectively avoids the stress concentration caused by welding reinforcement plates in the existing front positioning rotary lock seat and front sealing frame, and greatly reduces the welding amount, reduces the processing process and welding time, saves time and effort, and has a low labor cost.
[0011] Furthermore, an internal reinforcement plate is welded at the front part between the left side plate and the right side plate of the lock seat body to ensure the self-strength of the lock seat body and high reliability. Description of the Drawings
