[0043] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0044] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A luggage wheel brake device includes a shell 1, which can wrap the bottom corner of the luggage and is fixedly connected to the luggage. The bottom of the shell 1 is a fan-shaped transition surface, and a wheel frame 2 is connected to the shell 1. Guide wheels 3 are arranged on both sides of the wheel frame 2. The guide wheels 3 on both sides are distributed correspondingly to each other. The guide wheels 3 on both sides are connected by a connecting member 4, and the connecting member 4 is provided with a wheel frame 2. The wheel frame 2 is provided with a brake mechanism 5 for braking the guide wheel 3, which not only makes the brake more stable and is more conducive to meeting the use requirements, but also has a simpler structure, which is convenient for production and manufacturing, greatly reduces the cost of production and manufacturing, is conducive to mass production and manufacturing, and is also conducive to large-scale promotion and application. That is, the shell 1 of the utility model can be a part of the box, which is more conducive to a more stable structure.

[0045] like Figure 1 As shown, when in use, one only needs to step on the brake mechanism 5 with one's foot, and the brake mechanism 5 will clamp the guide wheels 3 on both sides of the wheel frame 2, so that the guide wheels 3 on both sides of the wheel frame 1 will not roll, thereby achieving a braking effect. When the brake mechanism 5 is stepped on with one's foot again, the brake mechanism 5 will withdraw from clamping the guide wheels 3 on both sides of the wheel frame 1, and finally the guide wheels 3 on both sides of the wheel frame 1 can move and rotate again.

[0046] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the brake mechanism 5 includes a push rod 51 arranged on the wheel frame 2 and capable of moving back and forth under external force, and a rotating body 52, a slider 53 and a block member 54 arranged inside the wheel frame 2. The lower end of the push rod 51 is provided with a rotating body 52, and the lower end surface of the rotating body 52 is provided with a slider 53. The lower end surface of the slider 53 cooperates with the block member 54. The up and down movement of the slider 53 causes the block member 54 to move back and forth horizontally. The push rod 51 and the rotating body 52 cooperate with each other to drive the slider 53 to move up and down. The lower end surface of the slider 53 is provided with a return member 55 for returning the slider 53. In the utility model, the guide wheel 3 is placed on the ground as a conventional form, and then the internal components perform various movements, such as up and down movement and horizontal movement, etc., which enables the slider 53 to move up and down, and the up and down movement of the slider 53 causes the block member 54 to move back and forth horizontally, and the wheel The frame 2 is provided with a reset member 56 for resetting the block member 54, and the corresponding guide wheels 3 are provided with a latching position 57 for cooperating with the block member 54. When in use, by pressing the push rod 51, the descent of the push rod 51 will cause the rotating body 52 to also move downward, and the rotating body 52 also prompts the slider 53 to move downward. The slider 53 will cause the block member 54 to move in the latching position 57 in the direction of the guide wheel 3. At this time, the guide wheel 3 can be stuck and cannot rotate. At the same time, when the slider 53 moves downward, the return member 55 is compressed, which is conducive to the upward return of the slider 53, and the reset member 56 on the block member 54 is also in a compressed state. When the push rod 51 is pressed again, the block member 54 and the slider 53 will return to their original positions under the action of the return member 55 and the reset member 56, so that the guide wheel 3 is unlocked and can rotate and walk again.

[0047] Among them Figure 2 As shown, a lower ratchet gear 511 is disposed on the lower end surface of the push rod 51, and an upper ratchet gear 521 is disposed on the upper end surface of the rotating body 52. ​​The lower ratchet gear 511 and the upper ratchet gear 521 cooperate with each other to enable the rotating body 52 to move up and down.

[0048] Among them Figure 2As shown, the slider 53 includes a column 531 arranged on the lower end surface of the rotating body 52, and a block 532 is arranged on the column 531. In the present embodiment, the column 531 and the block 532 are integrally formed, which greatly improves the firmness of the structure. The lower end surface of the block 532 is provided with an inclined surface 533, and the clamping member 54 includes a main block 541 and a clamping body 542 arranged on the main block 541. A reset member 56 is sleeved on the clamping member 54, and an inclined matching surface 543 is provided on the main block 541. The inclined surface 533 and the inclined matching surface 543 cooperate with each other so that the clamping member 54 and the clamping position 57 are clamped with each other to achieve a braking effect. When the slider 53 moves downward, the inclined surface 533 of the lower end surface of the block 532 will cooperate with the inclined matching surface 543 on the main block 541 to promote the horizontal movement of the block 54, so that the guide wheel 3 cannot rotate after the block 542 is inserted into the locking position 57, which has the effect of braking. When the block 542 is out of the locking position 57, the guide wheel 3 will rotate. It is worth noting that the lower end surface of the block 532 is provided with a positioning column 534 for positioning the return member 55, and this arrangement is more conducive to the installation of the return member 55. It is also worth noting that in this embodiment, the block members 54 are distributed in pairs, and each block member 54 is provided with a reset member 56, which is conducive to the automatic reset of the block member 54.

[0049] The return member 55 and the reset member 56 are both springs, which are widely available and are convenient for returning the block member 54 and the slider 53 .

[0050] Among them Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, it also includes a sleeve 58 for installing the rotating body 52. ​​The sleeve 58 is provided with a limiting groove inside for the push rod 51 to make axial movement. In this embodiment, the limiting grooves are evenly spaced on the inner wall of the sleeve 58, and the lower position of the push rod 51 is provided with a lower protrusion that cooperates with the limiting groove. The lower protrusion cooperates with the limiting groove so that the push rod 51 can only make axial movement.

[0051] Among them Figure 2 and Figure 6 As shown, a fixing plate 59 for mounting the outer sleeve 58 is disposed on the connecting member 4, and the fixing plate 59 is disposed on the wheel frame 2. This arrangement is reasonable and convenient for disassembly and installation.

[0052] When the push rod 51 is in use, it only needs to press the push rod 51. Since the push rod 51 can only move downward due to the restriction groove in the outer sleeve 58, the ratchet gear 511 on the lower end surface of the push rod 51 will cooperate with the upper ratchet gear 521 on the upper end surface of the rotating body 52, and the rotating body 52 will also cause the slider 53 to move downward, and the slider 53 will cause the block member 54 to move in the block position 57 in the direction of the guide wheel 3. At this time, the guide wheel 3 can be stuck and cannot rotate. At the same time, when the slider 53 moves downward, the return member 55 is compressed, which is conducive to the upward return of the slider 53, and the reset member 56 on the block member 54 is also in a compressed state; and when the push rod 51 is pressed again, the push rod 51 will cause the rotating body 52 and the slider 53 to return to their original positions under the action of the return member 55 and the reset member 56, so that the block member 54 and the slider 53 are unlocked, and the guide wheel 3 can be rotated and walked again.

[0053] Among them Figure 5 and Figure 6 As shown, the latching position 57 is a latching groove evenly spaced apart on the guide wheel 3 , and in this embodiment, the latching grooves are evenly spaced apart on the opposite vertical surface of the guide wheel 3 . This arrangement is reasonable and more conducive to the use in conjunction with the latching block 54 .

[0054] Embodiment 3: It can be explained on the basis of embodiment 1 or embodiment 2 that the guide wheel 3 includes corresponding rollers, and the rollers are connected by a connecting member 4, which is conducive to the installation of the rollers. It is to be noted that the first bearing 31 corresponding to the roller on the connecting member 4 is conducive to preventing the roller 31 from swinging, which is more conducive to meeting the use requirements.

[0055] Embodiment 4: It can be described on the basis of embodiment 1 or embodiment 2 or embodiment 3 that the connecting member 4 includes an intermediate shaft and rivets arranged on both ends of the intermediate shaft. This arrangement is more conducive to a tighter installation of the guide wheel 3 and better meets the use requirements.

[0056] Embodiment 5: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the shell 1 and the wheel frame 2 are connected by a shock-absorbing bracket 6. This arrangement is conducive to achieving a shock-absorbing effect on the shell 1. It should be noted that the shock-absorbing bracket 6 includes a fixing member 61 installed on the wheel frame 2, the other end of the fixing member 61 is fixed on the shell 1, and a second bearing 62 is arranged on the fixing member 61. The second bearing 62 can realize the rotation of the shell 1. A compression member 63 is arranged on the fixing member 61, and the compression member 63 is located below the second bearing 62. This is conducive to achieving a shock-absorbing effect on the luggage of the utility model and can better meet the use requirements. It should be noted that the fixing member 61 is provided with an upper gasket 64 and a lower gasket 65 for protecting the second bearing 62. This arrangement is more conducive to protecting the second bearing 62 to a certain extent and improving the service life.

[0057] The fixing member 61 is a rivet, which is widely available and easy to implement.

[0058] The compression member 63 is a spring, which is convenient for implementation.

[0059] The shell 1 of the utility model can rotate on the second bearing 62, and the compression member 63 can achieve a shock-absorbing effect. The upper side of the shell 1 can also be designed to be compatible with the corners of the bag, so it can be better covered with the bag and effectively protect the corners of the bag without affecting the overall appearance.

[0060] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0061] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
