Description

Technical Field

[0001] The utility model relates to the technical field of silent trolley bags, in particular to a trolley bag with ultra - silent movement. Background Art

[0002] With the acceleration of the modern social life rhythm, people's demand for traveling and carrying items is increasing day by day. As a convenient carrying tool, the trolley bag has been widely used in people's daily life. However, there are still certain limitations in the design and function of traditional trolley bags, especially in terms of noise control and moving convenience. First of all, during the movement of traditional trolley bags, due to the friction between the wheels and the ground, and the collision of the connecting parts between the trolley and the bag body during movement, relatively large noises are often generated. This not only affects the user experience but may also cause unnecessary embarrassment or interference in specific situations. Secondly, although the trolley bag is designed to facilitate carrying heavy objects, in actual use, when there are more or heavier items in the bag, the wheels and the trolley of traditional trolley bags often cannot bear this weight, resulting in difficult movement, and may even damage the bag body or the wheels. Moreover, the intensity of the noise will increase with the weight in the bag. Content of the Utility Model

[0003] To overcome the technical defects existing in the prior art, the utility model provides a trolley bag with ultra - silent movement. The wheels at the bottom of this utility model adopt double - row aircraft wheels. The outer part of the hub of the sound - absorbing universal wheel is also wrapped with a wheel skin, and sound - absorbing cotton is arranged in the sound - insulating cavity around the sound - absorbing universal wheel, ensuring the silent effect during the movement of the trolley bag. A buffer material is added at the connection between the bag body and the metal, further improving the silent performance of the trolley bag during movement, and ensuring that relatively small noises are generated during the movement of the trolley bag.

[0004] The technical solution adopted by the utility model is: a mobile ultra-quiet trolley bag, including a bag body. A side handle is provided on the side of the bag body, which can facilitate the user to carry the trolley bag by hand when the roller cannot be used. A back plate is provided on the vertical surface of the bag body. Two telescopic cavities are symmetrically arranged inside the back plate. Buffer cotton is provided at the contact part between the telescopic cavity and the back plate, which can reduce the noise generated by the collision between the bag body and the metal. Telescopic rods are arranged inside both of the two telescopic cavities. A rod handle is provided at the top of the telescopic rod, which is convenient for the user to support and pull away the bag body and can also support the bag body. A lifting button is provided on the top of the rod handle. Pressing the lifting button can pull out the telescopic rod. A limiting device is provided at the connection between the telescopic rod and the telescopic cavity. The limiting device can position the pulled-out telescopic rod to prevent it from retracting into the telescopic cavity. An uneven cushion plate is provided at the bottom of the bag body. The uneven cushion plate can support the bag body and can also prevent the bag body from being soiled or wetted when placed on the ground. A sound insulation cavity is provided at one end of the bottom of the bag body. The sound insulation cavity can reduce the noise generated when the roller rolls to a certain extent. A sound-absorbing universal wheel is arranged inside the sound insulation cavity.

[0005] Preferably, a top plate is arranged inside the rod handle. The bottom of the lifting button is connected to the upper surface of the top plate. When the lifting button is pressed, the top plate can move downward. Limiting long rods are arranged inside both of the two telescopic rods. The top of the limiting long rod is connected to the lower surface of the top plate. When the top plate moves downward, the two limiting long rods will move downward accordingly. Springs are arranged at the tops of both of the two telescopic rods. The top of the spring is fixed on the lower surface of the top plate. When the limiting long rod moves downward, the spring stretches. When the lifting button is released, the spring retracts and the top plate moves upward, and the limiting long rod moves upward accordingly.

[0006] Preferably, the limiting device includes a limiting ball and an elastic piece. The limiting ball is located in a circular hole opened on the bottom surface of the telescopic rod. One end of the elastic piece is connected to the limiting ball, and the other end is connected to the limiting long rod. When the limiting long rod moves downward, the elastic piece bends, and the limiting ball moves out of the circular hole and enters the inside of the telescopic rod. At this time, the telescopic rod can be retracted into the telescopic cavity for storage. When the telescopic rod is pulled out from the inside of the telescopic cavity, the elastic piece straightens, and the limiting ball pops out into the circular hole. At this time, the pulled-out telescopic rod can be fixed.

[0007] Preferably, the sound insulation cavity is composed of a universal wheel top plate, two universal wheel side plates and a universal wheel rear plate. Sound-absorbing cotton is added inside the universal wheel top plate, the universal wheel side plates and the universal wheel rear plate. The noise generated when the roller rolls will be absorbed by the sound-absorbing cotton inside the sound insulation cavity.

[0008] Preferably, a number of small bosses are evenly arranged in an array on the concave-convex cushion plate. The concave-convex cushion plate is made of a rubber material with a relatively high hardness, which can effectively isolate the contact between the package body and the bottom surface, preventing it from getting dirty or coming into contact with the water stains on the bottom surface.

[0009] Preferably, the noise-reducing universal wheel includes a top buffer pad. The buffer pad can effectively reduce the impact on the package body when the noise-reducing universal wheel rolls. A wheel column is provided at the bottom of the buffer pad, and the wheel column plays a supporting role for the noise-reducing universal wheel. The buffer pad and the wheel column are connected by a rotating rod, and the rotating rod enables the noise-reducing universal wheel to turn. A wheel shaft is penetrated through the bottom of the wheel column, and wheels are provided at both ends of the wheel shaft, and the wheels rotate on the wheel shaft.

[0010] Preferably, sound-absorbing cotton is filled inside both the buffer pad and the wheel column. The sound-absorbing cotton can reduce the noise generated by the vibration when the wheels rotate.

[0011] Preferably, the wheel is composed of a wheel hub, a shaft sleeve and a wheel skin. The shaft sleeve is sleeved on the inner circle of the wheel hub, the wheel shaft rotates and penetrates inside the shaft sleeve, and the wheel skin is wrapped on the outer circle of the wheel hub. The combination of the wheel hub, the shaft sleeve and the wheel skin can effectively reduce the noise generated when the wheel rolls.

[0012] The beneficial effects of the present utility model are as follows: The noise-reducing universal wheels at the bottom of this utility model adopt double-row aircraft wheels, and the combination of the wheel hub, the shaft sleeve and the wheel skin is also adopted, which can effectively reduce the noise generated when the wheels roll. Sound-absorbing cotton is also provided in the sound-insulating cavity on the periphery of the noise-reducing universal wheel, further ensuring the sound insulation effect during the movement of the rolling suitcase. Buffer materials are added at the connection between the package body and the metal, further improving the sound insulation performance of the rolling suitcase during movement.

Specific embodiments

[0021] The present utility model will be further described below with reference to the accompanying drawings:

[0022] As Figures 1-7 shown, this embodiment provides a mobile ultra-quiet rolling bag, including a bag body 1. A side handle 2 is provided on the side of the bag body 1, which can facilitate the user to carry the rolling bag by hand when the rollers cannot be used. A back plate 7 is provided on the vertical surface of the bag body 1. Two telescopic cavities 6 are symmetrically arranged inside the back plate 7. Buffer cotton is provided at the contact part between the telescopic cavity 6 and the back plate 7, which can reduce the noise generated by the collision between the bag body 1 and the metal. Telescopic rods 3 are arranged inside both telescopic cavities 6. When the bag body 1 is not pulled, the telescopic rods 3 can be retracted into the telescopic cavities 6, reducing the volume of the entire bag body 1. A rod handle 4 is provided at the top of the telescopic rod 3, which is convenient for the user to hold and pull the bag body 1, and can also support the bag body 1. A lifting button 5 is provided at the top of the rod handle 4. Pressing the lifting button 5 can pull out the telescopic rod 3. A limiting device 11 is provided at the connection between the telescopic rod 3 and the telescopic cavity 6. The limiting device 11 can position the pulled-out telescopic rod 3 to prevent it from retracting into the telescopic cavity 6. A concave-convex backing plate 10 is provided at the bottom of the bag body 1. The concave-convex backing plate 10 can support the bag body 1 and can also prevent the bag body 1 from being soiled or wetted when placed on the ground. A sound insulation cavity 8 is provided at one end of the bottom of the bag body 1. The sound insulation cavity 8 can reduce the noise generated by the rolling of the rollers to a certain extent. A sound-absorbing universal wheel 9 is arranged inside the sound insulation cavity 8.

[0023] Inside the rod handle 4, there is a top plate 401. The bottom of the lifting button 5 is connected to the upper surface of the top plate 401. Inside both telescopic rods 3, there is a limit long rod 402. The top of the limit long rod 402 is connected to the lower surface of the top plate 401. At the top of both telescopic rods 3, there is a spring 403. The top of the spring 403 is fixed on the lower surface of the top plate 401. When the lifting button 5 is pressed, the top plate 401 can move downward, and the two limit long rods 402 will move downward accordingly. At this time, the spring 403 is stretched. When the lifting button 5 is released, the spring 403 retracts, the top plate 401 moves upward, and the limit long rod 402 moves upward accordingly.

[0024] The limiting device 11 includes a limiting ball 1101 and a spring piece 1102. The limiting ball 1101 is located in a circular hole opened on one side of the bottom of the telescopic rod 3. One end of the spring piece 1102 is connected to the limiting ball 1101, and the other end is connected to the limit long rod 402. When the lifting button 5 is pressed, the limit long rod 402 moves downward, the spring piece 1102 bends, and the limiting ball 1101 moves out of the circular hole and into the inside of the telescopic rod 3. At this time, the telescopic rod 3 can be retracted into the telescopic cavity 6 for storage. When the telescopic rod 3 is pulled out from the inside of the telescopic cavity 6, the spring piece 1102 straightens, and the limiting ball 1101 pops out into the circular hole. At this time, the pulled-out telescopic rod 3 can be fixed.

[0025] The sound insulation cavity 8 is composed of a universal wheel top plate 801, two universal wheel side plates 803, and a universal wheel rear plate 802. Sound insulation cotton is added inside the universal wheel top plate 801, the universal wheel side plates 803, and the universal wheel rear plate 802. The sound insulation cotton here can absorb a large amount of the noise generated when the rollers roll. A number of small convex platforms are evenly arranged in an array on the concave-convex cushion plate 10. The concave-convex cushion plate 10 is made of a rubber material with a relatively high hardness. The high hardness can support the bag body 1, and the rubber material can prevent water and isolate the bag body 1 from the ground.

[0026] The sound-absorbing universal wheel 9 includes a top buffer pad 901, which plays a buffering role. At the bottom of the buffer pad 901, there is a wheel column 903, which supports the sound-absorbing universal wheel 9. The buffer pad 901 and the wheel column 903 are connected by a rotating rod 902, and the rotating rod 902 can enable the sound-absorbing universal wheel 9 to turn. The bottom of the wheel column 903 is provided with a wheel shaft 905, and wheels 904 are arranged at both ends of the wheel shaft 905. The wheels 904 rotate on the wheel shaft 905. Sound-absorbing cotton is filled inside the buffer pad 901 and the wheel column 903. The sound-absorbing cotton here can further reduce the noise generated by the vibration when the wheels 904 rotate.

[0027] The wheel 904 is composed of a wheel hub 9041, a bush 9042 and a tyre 9043. The bush 9042 is sleeved on the inner circle of the wheel hub 9041. The axle 905 rotates through the inside of the bush 9042. The tyre 9043 wraps around the outer circle of the wheel hub 9041. The combination of the wheel hub 9041, the bush 9042 and the tyre 9043 can effectively reduce the noise generated when the wheel 904 rolls. The tyre 9043 can buffer when it contacts the ground and produces relatively little noise.
