Description
Technical Field
[0001] The utility model relates to the technical field of folding scooter accessories, and specifically, to a high-toughness aluminum alloy folding joint. Background Technique
[0002] A folding scooter is a means of transportation that combines the characteristics of a skateboard and a motorcycle. It has the advantages of being foldable and portable, and can fold the body into a smaller size, which is convenient for carrying and storing. The overall components of a folding scooter are relatively numerous, but its folding parts are generally connected through folding joints. There are many types of folding joints on the market, and most of the folding joints are made of aluminum alloy materials. The aluminum alloy materials have relatively high hardness and toughness, are not easily worn or broken, and are beneficial to extending the service life.
[0003] When a conventional aluminum alloy folding joint is in use, since the two components are rotatably connected, the folding operation is more convenient. However, some aluminum alloy folding joint parts lack corresponding limiting components and cannot perform limiting operations, resulting in the inability to fix the rotatable connection part, and it is easy to rotate during use, affecting the stability of the handle part. There are also some aluminum alloy folding joint parts that are provided with limiting components, but the limiting components use torsion springs, etc. for limiting. Since the torsion spring has elasticity and is prone to displacement when stressed, it will also cause the situation of insufficient firmness of the limit, affecting the use effect. In view of this, we have proposed a high-toughness aluminum alloy folding joint. Content of the Utility Model
[0004] The purpose of the utility model is to provide a high-toughness aluminum alloy folding joint to solve the defects mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution:
[0006] A high-toughness aluminum alloy folding joint, including a hinge seat. An assembly groove is provided on the hinge seat. A clamping groove is provided on one side groove wall of the assembly groove. A storage groove is provided on the rear side groove wall of the assembly groove. A column is provided on the hinge seat.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a high-toughness aluminum alloy folding joint, including a hinge seat 1, an assembly groove 10 is provided on the hinge seat 1, a card slot 11 is provided on one side wall of the assembly groove 10, a storage groove 12 is provided on the rear side wall of the assembly groove 10, a column 2 is provided on the hinge seat 1, a hinge disc 20 is fixedly installed at the bottom end of the column 2, and the hinge disc 20 is located in the assembly groove 10 and is hinged to the hinge seat 1, so that the column 2 can rotate normally to realize the unfolding and folding operations;
[0026] Specifically, two limit grooves 21 with an included angle less than 90 degrees are provided on the hinge disc 20, a limit component 3 is provided in the assembly groove 10, and the limit component 3 includes an end card plate 30 arranged in the storage groove 12 and slidably connected to the storage groove 12. The end card plate 30 is inserted into the corresponding limit groove 21 for limit operation to realize the limit of the hinge disc 20 and further ensure that the column 2 will not rotate easily;
[0027] Specifically, a plurality of springs 34 arranged at equal intervals are provided between the rear side surface of the end clamping plate 30 and the rear side wall of the storage groove 12. Both ends of the spring 34 are fixedly installed on the rear side surface of the end clamping plate 30 and the rear side wall of the storage groove 12 respectively, so that the spring 34 will not become loose; further ensuring that under the elastic force of the spring 34, the end plate body of the end clamping plate 30 is more stably clamped into the corresponding limiting groove 21.
[0028] In this embodiment, a U-shaped seat 35 is fixedly installed on the top surface of the end clamping plate 30. A handle 36 is rotatably connected to the U-shaped seat 35. The handle 36 is in clamping fit with the clamping groove 11, which is convenient for performing a limiting operation on the handle 36, realizing the limiting of the end clamping plate 30, so that the handle 36 and the end clamping plate 30 will not move back and forth, achieving the effect of double limiting.
[0029] In this embodiment, the whole device is made of aluminum alloy material, and the aluminum alloy material is quenched, so that the overall hardness and toughness are greater, it is not easy to break, and it is beneficial to extend the service life.
[0030] Specifically, sliding grooves 13 are provided on the left and right side walls of the assembly groove 10. Sliders 33 are fixedly installed on the left and right side surfaces of the end clamping plate 30. The sliders 33 are located in the sliding grooves 13 and are slidably connected to the sliding grooves 13, which is convenient for guiding the movement of the end clamping plate 30.
[0031] Furthermore, a guide rod 131 arranged along the length direction of the sliding groove 13 is fixedly installed on the front side wall of the sliding groove 13. A guide hole 331 is provided in the slider 33. The guide rod 131 passes through the guide hole 331, and the slider 33 is slidably connected to the guide rod 131, so that the slider 33 slides more smoothly.
[0032] In addition, the size of the sliding groove 13 is adapted to the size of the sliding groove 13, and the size of the end clamping plate 30 is adapted to the size of the storage groove 12, making the overall structure more stable.
[0033] It should be noted that a front end head 31 is fixedly installed at the front end of the end clamping plate 30. The thickness of the front end head 31 is smaller than the thickness of the end clamping plate 30, which is used for smoothly inserting into the limiting groove 21, so that the front end head 31 is inserted more smoothly along the limiting groove 21.
[0034] It should be noted that an arc surface 32 is provided between the rear end of the front end head 31 and the front side surface of the end clamping plate 30. The arc surface 32 is used to reduce friction, so that the front end head 31 and the front end plate body of the end clamping plate 30 are inserted more smoothly along the storage groove 12.
[0035] When the high-toughness aluminum alloy folding joint of the utility model is in use, the handle 36 is first pushed backward until the rear end plate body of the end clamping plate 30 is stored in the storage groove 12, and then the column 2 is unfolded or closed. After the unfolding or closing is completed, the handle 36 is released. At this time, under the elastic force of the spring 34, the end clamping plate 30 can be driven to slide forward, so that the end plate body and the front end head 31 of the end clamping plate 30 are inserted into the limiting groove 21, thereby limiting the hinge plate 20 and making the hinge plate 20 unable to rotate easily. Then, the handle 36 is turned to clamp the handle 36 into the clamping groove 11. At this time, the groove walls on the left and right sides of the clamping groove 11 limit the handle 36, so that the handle 36 will not move forward and backward, and the end clamping plate 30 will not move forward and backward, thereby ensuring that the end clamping plate 30 will not detach from the limiting groove 21, thereby completing double fixation.
[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
