Description

[Technical field]

[0001] The utility model relates to a luggage case castor brake structure. [Background technology]

[0002] A suitcase is a storage box that is convenient for people to carry items when going out, on business trips, or traveling. It is equipped with a telescopic pull rod and casters to facilitate users to drag it. Currently, suitcases on the market have brakes at the caster position. Usually, the brake is stepped on with the foot and then hooked upward to release the brake. Although this method has a good effect of stopping the caster, the user often slips when using the foot to hook the brake device to unlock it, resulting in failure to release the caster brake. [Contents of the utility model]

[0003] The purpose of the present invention is to overcome the above problems. We provide a luggage case caster brake structure, which can improve the success rate of users operating the brakes and releasing the brakes.

[0004] To achieve the above-mentioned purpose, the utility model provides a luggage case caster brake structure, including a caster frame and a caster mounted on the caster frame, the caster frame is provided with a brake assembly for stopping the caster, the brake assembly includes a mounting frame, a brake pad, a first foot pedal and a second foot pedal, the mounting frame is fixed to the caster frame, the brake surface of the brake pad is arranged toward the caster and is rotatably connected to the mounting frame, the first foot pedal is arranged on the outer side of the brake pad and is rotatably connected to the brake pad, and the second foot pedal is arranged on the outer side of the first foot pedal and is rotatably connected to the first foot pedal and the mounting frame respectively.

[0005] In one or more embodiments, a pivot seat is provided on the outer side surface of the brake pad, a pivot shaft portion connected to the pivot seat is provided on the first pedal portion, and the brake pad is rotatably connected to the mounting frame via the first pivot shaft.

[0006] In one or more embodiments, the first foot-operated portion has a first pivot axis hole, the second foot-operated portion has a second pivot axis hole, and the first pivot axis hole and the second pivot axis hole are connected via a second pivot.

[0007] In one or more embodiments, third pivot holes are provided on both sides of the mounting frame, and shaft columns connected to the third pivot holes are provided on both sides of the second footrest portion.

[0008] In one or more embodiments, the outer side surfaces of the first footrest portion and the second footrest portion are provided with anti-slip structures.

[0009] In one or more embodiments, the outer side surfaces of the first foot-resting portion and the second foot-resting portion are foot-resting surfaces, and the foot-resting area of ​​the first foot-resting portion is larger than the foot-resting area of ​​the second foot-resting portion.

[0010] In one or more embodiments, a plurality of convex ribs are distributed on the braking surface of the brake pad.

[0011] Compared with the background technology, the utility model has the following effects: the caster brake structure is different from the brake structure currently on the market, and is provided with a first foot-operated part and a second foot-operated part. The brake structure can be braked or unlocked by stepping on different foot-operated parts. Compared with the operation of hooking the brake and unlocking it with the foot, the success rate of the operation is higher.

[0014] Figure 3 It is an exploded view of the brake structure of the utility model. [Specific implementation method]

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0016] Please see Figure 1-3 The present application provides a luggage case caster brake structure, including a caster frame 1 and a caster 2 mounted on the caster frame, the caster frame 1 is provided with a brake assembly for stopping the caster, the brake assembly includes a mounting frame 3, a brake pad 4, a first pedal portion 5 and a second pedal portion 6, the mounting frame 3 is fixed to the caster frame 1, the brake surface of the brake pad 4 is arranged toward the caster 2 and is rotatably connected to the mounting frame, the first pedal portion 5 is arranged on the outside of the brake pad 4 and is rotatably connected to the brake pad, the second pedal portion 6 is arranged on the outside of the first pedal portion 5 and is rotatably connected to the first pedal portion and the mounting frame 3 respectively. With this structure, the brake pad, the first pedal portion and the second pedal portion are linked to each other. When the user steps on the second pedal portion, as shown in FIG. Figure 2 As shown in FIG. 1 , the brake pad leaves the caster and is in a state of unlocking the caster; when the user steps on the first pedal, as shown in FIG. Figure 1 As shown, the brake pad is pressed against the caster to stop the caster. Since the switching between the unlocking and braking states is performed by "stepping down", the success rate of the user's braking and unlocking is higher, and it is more convenient for the user to operate and use.

[0017] Specifically, a pivot seat 7 is provided on the outer side surface of the brake pad 4, and a pivot shaft portion 8 connected to the pivot seat is provided on the first pedal portion 5. The brake pad 4 is rotatably connected to the mounting frame via a first pivot shaft 9. The pivot structure can improve the reliability and linkage speed of the brake pad and the first pedal portion when they cooperate with each other.

[0018] The first foot pedal part 5 has a first pivot axis hole 10, and the second foot pedal part 6 has a second pivot axis hole 11. The first pivot axis hole and the second pivot axis hole are connected by a second pivot 12. With this structure, the first foot pedal part and the second foot pedal part are easy to assemble and disassemble, and the coordination and linkage between the two are better and more stable.

[0019] The mounting frame 3 is provided with a third pivot axis hole 13 on both sides, and the second foot-operated portion 6 is provided with a shaft column portion 14 connected to the third pivot axis hole on both sides. An arc-shaped transition structure is provided at the connecting end of the pivot column portion to facilitate easier insertion into the third pivot axis hole, which has the advantages of easy installation and disassembly, good reliability and linkage.

[0020] In order to prevent the user from slipping and improve the success rate of stepping on the pedal, the outer side surfaces of the first pedal portion 5 and the second pedal portion 6 are provided with anti-slip structures, which can be various raised pattern structures.

[0021] The outer side surfaces of the first foot-stepping portion 5 and the second foot-stepping portion 6 are foot-stepping surfaces, and the foot-stepping area of ​​the first foot-stepping portion is larger than that of the second foot-stepping portion. Since the second foot-stepping portion is located on the outer side of the first foot-stepping portion, in order to facilitate the user to step on the first foot-stepping portion more accurately, the foot-stepping area of ​​the first foot-stepping portion is set to be larger, which will be more conducive to the user stepping accurately.

[0022] The brake surface of the brake pad 4 is provided with a plurality of convex ribs 15 , which can increase the friction force and provide a better brake locking effect on the caster.

[0023] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
