Description

Technical Field

[0001] This utility model relates to the field of trailer components, specifically a pin-type column for semi-trailers. Background Technology

[0002] Semi-trailers play a crucial role in modern logistics transportation. Their pin-type uprights, as key components connecting the trailer body and frame and ensuring overall structural stability, directly impact transportation efficiency and safety. These uprights support and secure the cargo baskets, together forming the side or end structure of the semi-trailer body. They provide enclosure and support for the cargo, preventing it from falling during transport and ensuring its safety. During loading and unloading, the cargo baskets can be opened or lowered as needed, facilitating cargo entry, exit, and stacking, thus improving loading and unloading efficiency.

[0003] Traditional uprights typically use a direct insertion and removal of locating pins to fix and release their positioning. Conventional pin-type uprights lack a positioning device for the locating pins, so the locating pins need to be frequently inserted and removed during loading and unloading. Frequent and laborious insertion and removal operations can easily lead to wear and tear on the locating pins and other related components, reducing their service life and increasing maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to provide a pin-type column for semi-trailers to solve the problem mentioned in the background art of conventional columns lacking positioning pin limit.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a semi-trailer pin-type upright, comprising an upright and an extension column slidably installed within the upright, a positioning pin fixedly installed on the side wall of the extension column, a sliding hole for accommodating the positioning pin on one side of the upright, a hanging plate rotatably installed above the sliding hole on the upright, and a U-shaped groove for accommodating the positioning pin on the side wall of the hanging plate.

[0006] Preferably, the mounting plate has a protrusion integrally formed at the center position, and the U-shaped groove is located at the protrusion position.

[0007] Preferably, a screw is fixedly installed at the end of the positioning pin, and a roller is rotatably sleeved on the screw.

[0008] Preferably, the main body of the hanging plate has an inclined section located below the protrusion.

[0009] Preferably, the bottom of the inclined segment extends vertically from the main body to form a flange.

[0010] Preferably, the corners of the hanging plate are rounded for a smooth transition.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, through the cooperation of a hanging plate, a positioning pin, and rollers, allows the operator to simply lift the positioning pin equipped with rollers during the process of releasing the anchor post positioning. The clever mechanical cooperation between the rollers and the inclined section of the hanging plate automatically drives the hanging plate to deflect, allowing the positioning pin to slide smoothly to the limit position at the opening of the U-shaped groove. This enables the anchor post positioning to be released and repositioned quickly and conveniently, effectively improving the efficiency of trailer anchor post assembly and disassembly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: a semi-trailer pin-type upright, including an upright 1 and an extension column 2 slidably installed in the upright 1. A positioning pin 4 is fixedly installed on the side wall of the extension column 2. A sliding hole for accommodating the positioning pin 4 is provided on one side of the upright 1. A hanging plate 3 is rotatably installed on the upright 1 above the sliding hole. A U-shaped groove for accommodating the positioning pin 4 is provided on the side wall of the hanging plate 3. The U-shaped groove facilitates the positioning of the positioning pin 4. When the trailer basket needs to be opened, the extension column 2 can be fixedly inserted into the upright 1 through the hanging plate 3. The corners of the hanging plate 3 are all rounded for a smooth transition. The advantage of this design is to avoid sharp corners that could scratch the skin. A protrusion 7 is integrally formed at the center of the hanging plate 3. The U-shaped groove is located at the position of the protrusion 7. A screw 6 is fixedly installed at the end of the positioning pin 4. A roller 5 is rotatably sleeved on the screw 6. The roller 5 converts sliding friction into rolling friction, greatly reducing the wear of the parts. An inclined section 8 is provided below the protrusion 7 on the main body of the hanging plate 3. The inclined section 8 works in conjunction with the roller 5. When it is necessary to release the positioning of the column 1, the positioning pin 4 with the roller 5 is lifted upwards. When the positioning pin 4 slides until the roller 5 abuts against the inclined section 8 of the hanging plate 3, it will cause the hanging plate 3 to deflect to the right until the positioning pin 4 slides to the opening of the U-shaped groove. The hanging plate 3 then rotates back to its original position by its own gravity, and the positioning pin 4 is inserted into the U-shaped groove to limit the extension column 2. The bottom of the inclined section 8 extends vertically from the main body to form a flange 9. The flange 9 is designed to facilitate gripping the hanging plate 3. This application utilizes the cooperation of the mounting plate 3, the positioning pin 4, and the roller 5. During the process of releasing the positioning of the upright 1, the operator only needs to lift the positioning pin 4 equipped with the roller 5 upwards. The clever mechanical cooperation between the roller 5 and the inclined section 8 of the mounting plate 3 will automatically drive the mounting plate 3 to deflect, allowing the positioning pin 4 to slide smoothly to the opening of the U-shaped groove. This eliminates the need for back-and-forth insertion and removal when the upright 1 is opened, enabling quick and convenient release and repositioning of the upright 1, effectively improving the efficiency of trailer upright assembly and disassembly.
