Abstract
Description
Technical Field
[0001] The utility model relates to the field of luggage accessories, and particularly relates to a silent universal wheel for luggage. Background Art
[0002] When the existing universal wheel for luggage is dragged on the ground, since the wheel body of the universal wheel for luggage is generally made of a relatively hard material such as plastic, when it rolls in contact with the ground, it will generate a relatively large noise, which has an adverse impact on others and oneself. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is aimed at the deficiencies of the above-mentioned prior art.
[0004] Provide a silent universal wheel for luggage to reduce noise and reduce the impact on others or oneself caused by the noise generated during dragging.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a silent universal wheel for luggage, including a mounting seat connected to the luggage, a wheel seat rotatably connected to the mounting seat, and a wheel body rotatably connected to the wheel seat, characterized in that: an outer wheel coaxially arranged is provided in the circumferential direction of the wheel body, and an airbag is provided between the outer wheel and the wheel body.
[0006] A further setting of the utility model is: the airbag includes three annular airbags, each of the annular airbags is arranged on the outer surface of the circumferential direction of the wheel body, and each of the annular airbags is arranged along the axial direction of the wheel body. A first installation groove adapted to the annular airbag is axially opened on the outer surface of the circumferential direction of the wheel body. The inner wall of the outer wheel is provided with a second installation groove with the same number and adapted to the annular airbag corresponding to the first installation groove. Each of the annular airbags is sleeved between the corresponding first installation groove and the second installation groove.
[0007] The utility model with the above characteristics: the airbag plays a role in shock absorption, reduces the hardness of the wheel, and thus reduces the generation of noise.
[0008] A further setting of the utility model is: the axial height of the wheel body is the same as the axial height of the outer wheel. The first installation grooves are respectively arranged at both axial ends and the middle part of the outer surface of the circumferential direction of the wheel body. The second installation grooves are respectively arranged at both axial ends and the middle part of the inner wall of the outer wheel.
[0009] The utility model with the above characteristics: makes the annular airbags distributed at two poles and one midpoint of the wheel body and the outer wheel, so that the force is more uniform.
[0010] A further setting of the utility model is: each of the annular airbags is fixedly connected to the corresponding first installation groove and the second installation groove through an adhesive.
[0011] The utility model with the above characteristics: the annular airbag is fixedly connected with the wheel body and the outer wheel, avoiding mutual dislocation.
[0012] A further setting of the utility model is that the outer wheel is made of rubber.
[0013] The utility model with the above characteristics: has a relatively soft texture and will not make a large noise when contacting the ground.
[0014] The beneficial effect of the utility model is: reducing noise and reducing the impact on others or oneself caused by the noise generated during dragging.
[0015] The following further describes the present utility model in detail with reference to the drawings and embodiments. Description of the Drawings
[0016] Figure 1 It is a three-dimensional schematic diagram of an embodiment of the present utility model.
[0017] Figure 2 It is a cross-sectional schematic diagram of the wheel body, the outer wheel and the annular airbag of an embodiment of the present utility model. Detailed Embodiment
[0018] As Figure 1 、 Figure 2 shown, a silent type luggage universal wheel includes a mounting seat 1 connected to the luggage, a wheel seat 2 rotatably connected to the mounting seat 1, and a wheel body 3 rotatably connected to the wheel seat 2. An outer wheel 4 coaxial with the wheel body 3 is provided circumferentially on the wheel body 3. An airbag is provided between the outer wheel 4 and the wheel body 3. The airbag includes three annular airbags 5. Each annular airbag 5 is arranged on the circumferential outer surface of the wheel body 3, and each annular airbag 5 is arranged axially along the wheel body 3. A first mounting groove 6 adapted to the annular airbag 5 is axially formed on the circumferential outer surface of the wheel body 3. The inner wall of the outer wheel 4 is provided with the same number of second mounting grooves 7 corresponding to the first mounting groove 6 and adapted to the annular airbag 5. Each annular airbag 5 is sleeved between the corresponding first mounting groove 6 and the second mounting groove 7. The axial height of the wheel body 3 is the same as the axial height of the outer wheel 4. The first mounting grooves 6 are respectively arranged at both axial ends and the middle of the circumferential outer surface of the wheel body 3. The second mounting grooves 7 are respectively arranged at both axial ends and the middle of the inner wall of the outer wheel 4. Each annular airbag 5 is fixedly connected to the corresponding first mounting groove 6 and the second mounting groove 7 by glue. The outer wheel 4 is made of rubber.
[0019] The airbag absorbs shock, reduces the hardness of the wheel, and thus reduces the generation of noise. The annular airbags 5 are distributed at two poles and one midpoint of the wheel body 3 and the outer wheel 4, making the force more uniform. The annular airbags 5 are fixedly connected to the wheel body 3 and the outer wheel 4, avoiding mutual dislocation. The outer wheel 4 is made of rubber, has a relatively soft texture, and will not make a large noise when contacting the ground.
