The term is used only to distinguish one component from another. For example, a first component may be referred to as a second component, and similarly, a second component may be referred to as a first component, without departing from the teachings of the utility model concept. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] The terminology used herein is for the purpose of describing various embodiments only and is not intended to be limiting. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.
[0027] refer to Figures 1 to 5 According to a preferred embodiment of the present utility model, a vehicle overload warning flag is provided, wherein the structure of the vehicle overload warning flag is as follows: Figure 1 As shown, the vehicle overload warning flag includes a flagpole 10, and the flagpole 10 can be fitted with an external warning flag.
[0028] Furthermore, the vehicle overload warning flag includes a spring tube 20 and a connecting cap 30. The end of the connecting cap 30 mates with the end of the spring tube 20. Simultaneously, the end of the flagpole 10 passes through the connecting cap 30 and is placed inside the spring tube 20. Specifically, one side of the connecting cap 30 has a mating cavity, and the bottom wall forming the mating cavity also has an insertion hole. The end of the flagpole 10 can sequentially pass through the insertion hole and the mating cavity and be placed inside the spring tube 20. It is worth mentioning that the end of the spring tube 20 can be pressed into the mating cavity by compression to form an interference fit, or the spring tube 20 can be fixed by welding.
[0029] Specifically, the vehicle overload warning flag also includes a connecting block 40, which has a protrusion 41 that engages with the other end of the spring tube 20, i.e., the end of the spring tube 20 that faces away from the flagpole 10. It is worth noting that the protrusion 41 and the end of the spring tube 20 can be fixed by interference fit or welding.
[0030] It is worth mentioning that the end of the connecting block 40 away from the connecting cover 30 also has an inner cavity, and the outer wall of the connecting block 40 also has a limiting groove 401 with an opening. The limiting groove 401 is a hook-shaped limiting groove 401, and the limiting groove 401 is also connected to the inner cavity.
[0031] It should be noted that the vehicle overload warning flag also includes a quick-release component 50, which cooperates with the connecting block 40 and is configured to be quickly installed or removed by plugging and unplugging. Specifically, the quick-release component 50 includes an elastic element 51 and a movable block 52, with the elastic element 51 disposed in the inner cavity. The connection between the end of the elastic element 51 and the inner cavity can be either a movable fit, i.e., directly placed inside the inner cavity; or a fixed fit, using welding or other methods to limit the position of the end of the elastic element 51, wherein the elastic element 51 is a general-purpose spring. Specifically, one end of the movable block 52 is movably disposed in the inner cavity and abuts against the end of the elastic element 51, so as to compress the elastic element 51 by pressing it towards the protrusion 41, thereby compressing the elastic element 51. At the same time, the end of the movable block 52 pressing the elastic element 51 can move towards the protrusion 41. It is worth mentioning that the movable block 52 is cylindrical with a hollow inner cavity, allowing it to rotate around itself. The outer wall of the movable block 52 also has a limiting block 521, which is welded to the surface of the movable block 52. When the movable block 52 is inserted into the inner cavity, the limiting block 521 passes through the notch of the limiting groove 401 and moves towards the other end of the limiting groove 401. When the limiting block 521 has moved a predetermined distance, the user rotates the movable block 52, and through the force of the elastic element 51, the limiting block 521 directly abuts against the other end of the limiting groove 401, thereby limiting the position of the movable block 52.
[0032] Specifically, the vehicle overload warning flag also includes a connecting plate 60. The end of the movable block 52 opposite to the connecting cover 30 has a connecting portion, which is fixedly connected to the connecting plate 60. Specifically, the connecting portion can penetrate the connecting plate 60, so that the end of the movable block 52 abuts against the surface of the connecting plate 60. Simultaneously, the end of the connecting portion passing through the connecting plate 60 is threadedly connected to an external nut, thereby defining the position of the connecting plate 60. It is worth mentioning that the connecting plate 60 also has holes for installing bolts and nuts, allowing the connecting plate 60 to be installed on an external vehicle. Specifically, as... Figure 1 As shown, the connecting plate and the movable block are installed perpendicularly, i.e., at a 90° angle, and as... Figure 5 As shown, the connecting plate and the movable block are installed at an angle of 45°, which improves the installation versatility of this application by providing two different installation methods.
[0033] In summary, the vehicle overload warning flag described in the embodiments of this application is explained, which provides advantages such as ease of use, convenient installation and removal, and high practicality.
[0034] It is worth mentioning that, in this embodiment, the vehicle overload warning flag has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the vehicle overload warning flag provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.
