DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3The utility model provides an embodiment: a luggage caster with overweight prompt, comprising a wheel shell 1, wherein the wheel shell 1 is fixedly connected with luggage via connecting rivets 3 and gaskets 4, the wheel shell 1 is provided with four groups, which are respectively arranged at the four corners of the bottom of the luggage, the outer periphery of the connecting rivets 3 is slidably connected to the inside of the wheel shell 1, the outer periphery of the connecting rivets 3 is riveted to the inside of the luggage, the wheel shell 1 is fixed to the bottom of the luggage, the inner periphery of the gasket 4 is slidably connected to the outer periphery of the connecting rivets 3, the gasket 4 is located between the wheel shell 1 and the luggage, the contact area is increased, and the connection stability is improved. The connecting rivet 3 is slidably connected to the weighing bracket 2 on its outer periphery, and a pin hole 6 is provided inside the weighing bracket 2. A pin 5 for limiting and fixing is slidably connected inside the pin hole 6. A groove is provided on the outer periphery of the lower end of the connecting rivet 3, and the inner side of the pin 5 is clamped in the groove on the outer periphery of the connecting rivet 3, so that the connecting rivet 3 is connected to the weighing bracket 2. The inner wall of the top end of the weighing bracket 2 is elastically connected to a weighing excess limiter 9 through a weighing spring 7. When the weighing bracket 2 is not subjected to force, the weighing spring 7 will push the weighing bracket 2 upward. One end of the weighing spring 7 is fixedly connected to the inner wall of the top end of the weighing bracket 2, and the other end of the weighing spring 7 is fixedly connected to the inner wall of the bottom end of the weighing excess limiter 9. The top of the weighing excess limiter 9 is detachably connected to a weighing limiter 8, and the outer periphery of the weighing excess limiter 9 is provided with an excess color mark 9-1 with a relatively obvious color.

[0031] Reference Figure 2-Figure 4 The bottom end of the over-weighing limiter 9 contacts a weighing stroke positioning member 10, and the outer periphery of the weighing stroke positioning member 10 and the outer periphery of the weighing stroke positioning member 9 are slidably connected to the inside of the weighing bracket 2. The weighing bracket 2 limits the over-weighing limiter 9 and the weighing stroke positioning member 10 to slide up and down along the inner wall of the weighing bracket 2. A weighing stroke positioning hole 11 is provided inside the weighing stroke positioning member 10, and a weighing stroke fixing hole 13 is provided inside the weighing bracket 2. The weighing stroke fixing hole 13 is set to be a long strip with rounded corners at both ends. The inside of the weighing stroke positioning hole 11 is detachably connected to a caster assembly for convenient movement of the luggage through a wheel rivet 14, and the caster assembly includes a wheel 12 for convenient movement of the luggage. There are two groups of wheels 12, and the two groups of wheels 12 are symmetrically arranged on both sides of the weighing bracket 2 to increase the support area and improve the stability of the luggage. The center holes of the two groups of wheels 12 are fixedly connected to the weighing stroke positioning member 10 through wheel rivets 14. The outer periphery of the wheel rivet 14 is slidably connected to the inside of the weighing stroke fixed hole 13, so that the wheel 12 can rotate. The outer periphery of the wheel 12 is detachably connected to a wheel cover 15 for protecting the wheel 12. The top of the weighing bracket 2 is provided with a weight display hole 16. The outer periphery of the excess color mark 9-1 and the outer periphery of the weighing limiter 8 are slidably connected to the inside of the weight display hole 16. When the excess color mark 9-1 on the weighing excess limiter 9 comes out, it indicates that it is overweight.

[0032] Working principle: When you want to conveniently display whether the weight inside the bag exceeds the designed load-bearing capacity of the bag, after placing items inside the bag, lock the bag and place it vertically. At this time, the weight of the bag will be transferred to the weighing bracket 2 through the wheel shell 1. The weighing bracket 2 moves downward under the gravity and squeezes the weighing spring 7. The weighing spring 7 is compressed by the pressure and generates elastic force in the opposite direction. At this time, the wheel rivet 14 will not change its position under the support of the wheel 12, and the wheel rivet 14 will move along the weighing stroke fixed hole 13. Sliding upward, the weighing stroke positioning member 10 is driven to slide upward along the inner wall of the weighing bracket 2, the weighing stroke positioning member 10 drives the weighing excess limit member 9 to move upward, and the weighing excess limit member 9 drives the weighing limit member 8 to move upward. When the weighing limit member 8 just slides out of the weight display hole 16, it indicates that the weight in the suitcase and bag reaches the designed load-bearing capacity of the suitcase and bag. When the excess color mark 9-1 slides out of the weight display hole 16, it indicates that the weight exceeds the designed load-bearing capacity of the suitcase and bag, so that the user can understand the weight inside the suitcase and bag.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
