Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary intended for explaining the present invention, and should not be construed as limiting the present invention.

With reference to fig. 1 to 5, a limiting device 1 for a trailer according to an embodiment of the present invention includes: the limiting part 12 is arranged on the limiting seat 11 and can be switched between a first state and a second state, and the limiting part 12 is erected on the limiting seat 11 in the first state and is used for limiting articles transported on the trailer; the limiting member 12 is laid on the limiting seat 11 in the second state. That is, the position limiting member 12 on the position limiting base 11 can be adjusted between the standing state and the flat state, so that the user can adjust the position limiting member according to the volume or the shape of the transported object, and the like, thereby achieving the position limiting effect and being beneficial to improving the flexibility and the practicability of the position limiting device 1. For example, when the shape of the article to be transported is special, the limiting member 12 may be switched to the first state, so that the limiting member 12 may abut against the article, thereby improving the stability during transportation; when the object to be transported is large in size or is in a shape which is easy to stably place, the limiting part 12 can be converted into a second state, namely, the limiting part is flatly placed on the limiting seat 11, so that the space suitable for flatly placing the object is enlarged, and the transportation efficiency and the use flexibility are improved. Therefore, according to the utility model discloses stop device 1 can realize the transportation of multiple article, does benefit to and reduces the cost of transportation.

According to the utility model discloses stop device 1 can change the state of locating part 12 on spacing seat 11 to improve the flexibility and the stability of transportation, do benefit to and reduce cost of transportation.

When the trailer is used for transporting the steel coil 20 or round objects, the limiting piece 12 can be erected on the limiting seat 11 and can be abutted against the steel coil 20, so that the steel coil 20 is prevented from sliding off during transportation; when the volume of the transported article is large, the erected limiting part 12 may interfere with the transported article, and therefore the limiting part 12 can be converted into the second state, namely the limiting part 12 is flatly placed on the limiting seat 11, so that the transported article can be directly placed on the limiting seat 11, the transportation convenience is improved, and the transportation effect is improved.

Referring to fig. 1, in some embodiments of the present invention, the limiting member 12 includes: the position-limiting device comprises a first stopping portion 121 and a second stopping portion 122, wherein one end of the first stopping portion 121 is hinged to the limiting seat 11, one end of the second stopping portion 122 is hinged to the other end of the first stopping portion 121, and the other end of the second stopping portion 122 is slidably connected to the limiting seat 11 along the front-back direction, so that the position-limiting member 12 is switched between the first state and the second state. Specifically, when the sliding end of the second stopping portion 122 slides towards the direction close to the first stopping portion 121, the sliding end of the second stopping portion 122 is close to the hinged end of the first stopping portion 121 and the limiting seat 11, the position where the first stopping portion 121 is hinged to the second stopping portion 122 rotates, the first stopping portion 121 and the second stopping portion 122 stand on the limiting seat 11, wherein the height of the limiting member 12 standing on the limiting seat 11 can be adjusted according to the position of the sliding end of the second stopping portion 122, so as to adjust the standing state, and improve the limiting effect. When the sliding end of the second stopping portion 122 slides in a direction away from the first stopping portion 121, the sliding end of the second stopping portion 122 gradually moves away from the first stopping portion 121 and the hinged end of the limiting seat 11, and the first stopping portion 121 and the second stopping portion 122 are rotatably connected, so that the limiting member 12 can be gradually laid flat, and the limiting member 12 can be switched to the second state.
