Description

Swivel wheels and luggage with brakes

technical field

The utility model relates to a universal wheel with a brake and a suitcase with a brake function using the universal wheel, which belongs to the field of daily travel articles.

Background technique

Suitcase is the requisite daily necessities for people to go out on a trip, because the suitcase has flexible wheels, it is convenient and labor-saving and is favored by users. Wheels are flexible and labor-saving, but they also bring some disadvantages. For example, on trains, cars and other vehicles, the shaking of the car body will make the suitcase move by itself. The more flexible the wheels, the more serious this problem.

The commonly used method to limit the brake of the universal wheel is to install the brake device on the universal wheel, move the brake device to complete the brake, and then move it in the opposite direction to complete the brake release. This method is very inconvenient to use, and generally requires the user to bend over to operate .

Contents of the invention

One of purpose of the utility model is: design can conveniently brake the universal wheel.

Two of the purpose of this utility model is: design can conveniently brake the suitcase.

In order to solve the above-mentioned technical problems, the utility model is realized through the following technical solutions: a universal wheel with brakes, including brake pads, a lower pressing shaft, and a sleeve, and a spring is connected between the bottom of the sleeve and the lower pressing shaft, wherein: The brake pad is connected to the top of the lower final shaft, the side wall of the lower final shaft has an inward groove, the diameter of the lower final shaft above the groove is different from the diameter of the lower final shaft below the groove, and one or two fixed frame, the fixed frame withstands the groove when the pressing shaft is pressed down.

The diameter of the lower final shaft above the groove is greater than the diameter of the lower final shaft below the groove; the fixed frame can rotate at the central fulcrum, and a corner rod is connected to the top of the fixed frame, and the corner rod and the fixed frame are connected by an elastic member.

The slope of the angled rod is the same as the slope of the upper slope of the groove when it is extended to the maximum extent, and the extension of the angled rod cannot touch the lower pressing shaft below the groove.

The suitcase with brakes includes universal wheels, wherein the universal wheels are universal wheels with brakes.

The main beneficial effect of the utility model is that on a shaking vehicle or a place where the suitcase does not need to be moved, the user only needs to press down on the suitcase to complete the brake, and then press it again to reset without bending over Easy to operate and use.

detailed description

Further description will be made below in conjunction with drawings and embodiments.

The basic idea of the utility model is: the brake is completed by pressing the trunk, and the reset is reset by pressing again, which is convenient to use.

Embodiment 1: In this embodiment, a fixing frame 6 is fixedly connected to the side wall of the sleeve, and the sleeve is fixed at the central axis of the wheel 10. When the suitcase is in normal use, the universal wheel structure is shown in Figure 2: the brake The disc 1 and the wheel are in the stage of separation. At this time, the internal structure is shown in the state 1 of Figure 3. When the universal wheel needs to be braked, press the trunk, and the pressing shaft 2 compresses the spring 4 and moves down to the state 2 position in Figure 3; continue Pressing down, the angled rod 7 connected to the top of the fixed frame 6 touches the upper slope of the lower final shaft groove 5, and the angled rod 7 is forced to bend itself inward, and at the same time, this force acts on the upper end of the fixed frame 6 to make the fixed frame pass through the central fulcrum 9 along the Clockwise rotation, the bottom end of the fixed bracket is stuck in the groove, and the top of the fixed bracket contacts the inner wall of the sleeve pipe 3 and cannot move again, as shown in state 3 of Figure 3, at this time the brake pads and the wheels contact to play a braking role.

When the brake needs to be released, continue to press down on the trunk, move the lower pinch down and hit the upper slope of the groove on the lower end of the fixing frame, as shown in state 4 in Figure 3, so that the fixed frame rotates counterclockwise to state 5; at this time, the spring at the bottom of the down pinch Under the active force, the lower pressure shaft moves up, and the automatic reset passes through state 6 and reaches state 1 to complete the brake release.

Embodiment 2: In this embodiment, two fixing frames with the same structure are symmetrically fixedly connected to the side wall of the casing, which can better play the role of braking stability, and the other parts are the same as in Embodiment 1.
