Description

Technical Field

[0001] The utility model relates to the technical field of luggage wheels, in particular to a simple luggage wheel with a shock-absorbing function. Background Art

[0002] Luggage is one of the most commonly used daily necessities. While providing the convenience of carrying items, it also has obvious characteristics of the times and obvious fashion characteristics. In order to clearly reflect these characteristics, people have been constantly developing and experimenting with various materials, structures, aesthetics and performance used to make luggage. Common luggage is generally composed of multiple parts, among which the pulley assembly is an essential part of the trolley case. The traditional pulley assembly is generally fixed to the case body with a rigid connection, which causes severe vibration when dragging the suitcase on a relatively shaking road surface, which reduces the service life of the pulley itself and easily causes damage to the items in the case.

[0003] A bag using a spring shock-absorbing universal wheel disclosed in Chinese utility model CN202222905605.8 includes a box body and a pulley assembly. The pulley assembly includes a mounting shell, a snap-on shell, a wheel body, and a shock-absorbing assembly. The snap-on shell and the mounting shell are mutually buckled and fixed by fasteners. The shock-absorbing assembly includes a rotating shaft, a ball bearing, a top ring, a fixing bolt, and a spring. The outer ring of the ball bearing is fixedly connected to the snap-on shell, and the inner ring is sleeved on the rotating shaft. Compared with the prior art, the utility model provides a rotating shaft that can slide up and down in the vertical direction, and provides a spring for shock absorption, so that the external force is buffered and vibration-absorbed, the pulley is protected from damage, and the storage of items in the bag is facilitated. And by providing a ball bearing, when the wheel body rotates, the friction force will not be increased due to the elastic load caused by the elastic force, so that the pulley assembly rotates smoothly and rotates freely.

[0004] Although the use of springs allows the pulley and the box to have a buffering and shock-absorbing function, the use of ball bearings for horizontal rotation is more labor-saving, but the ball bearings may break due to excessive load, high temperature, insufficient lubrication, and insufficient hardness. At the same time, the entry of water and dust will also affect the service life of the ball bearings. The difficulty and cost of replacing bearings in the corresponding structure are high, so it is necessary to design a simpler shock-absorbing structure. Summary of the invention

[0005] In view of this, the utility model provides a simple luggage wheel with a shock-absorbing function to solve the above technical problems.

[0006] A simple luggage wheel with a shock-absorbing function comprises a mounting shell mounted on a luggage, a pulley arranged on one side of the mounting shell, and a shock-absorbing assembly connecting the mounting shell and the pulley. The mounting shell is provided with a plug hole for inserting the shock-absorbing assembly, a plurality of reinforcing ribs arranged around the plug hole, and a limiting sleeve arranged outside the plug hole. The plug hole is a circular through hole. The limiting sleeve is a cylindrical structure arranged around the plug hole and is located on the side of the plug hole close to the shock-absorbing assembly. The pulley comprises a connecting sleeve connected to the shock-absorbing assembly and at least one wheel body arranged on the connecting sleeve. A connecting hole is provided at one end of the connecting sleeve, and a cylindrical fixing sleeve is provided at the other end. The fixing sleeve is a cylindrical structure with a hollow axis. The shock-absorbing assembly comprises a rotating shaft inserted in the connecting sleeve, a rotating ring sleeved on the rotating shaft, a top ring sleeved on the rotating shaft, and a spring sleeved on the rotating shaft. One end of the rotating shaft passes through the jack, and the other end passes through the fixed sleeve and extends out from the opening at the bottom. Both ends of the rotating shaft are fixed in position by rivets. The rotating shaft is provided with an annular abutment top and a movable end. The movable end is the end of the rotating shaft away from the mounting shell. The diameter of the movable end is smaller than the main body diameter of the rotating shaft. The rotating ring, spring and abutment ring are sequentially sleeved on the rotating shaft starting from the abutment top. The spring is located between the rotating ring and the abutment ring, and abuts against the rotating ring and the abutment ring respectively. The abutment ring is located on the movable end.

[0007] Furthermore, the reinforcing rib is arranged around the insertion hole, extends in the axial direction of the insertion hole, and is located on a side of the mounting shell away from the shock-absorbing assembly.

[0008] Furthermore, the connecting hole is a through hole, and the opening direction is consistent with the horizontal plane.

[0009] Furthermore, the bottom of the fixing sleeve is open, and a plurality of reinforcing ribs are arranged at the opening, and the aperture of the opening is smaller than the diameter of the barrel of the fixing sleeve.

[0010] Furthermore, the wheel body is arranged on both sides of the connecting sleeve through fasteners and is located at an end away from the mounting shell.

[0011] Furthermore, the rotating shaft, rotating ring, spring and abutting ring are all made of metal.

[0012] Furthermore, the friction between the rotating ring and the rotating shaft, and between the abutting ring and the movable end is reduced by applying lubricating oil.

[0013] Furthermore, the abutment top portion is a metal ring integrally formed with the rotating shaft.

[0014] Compared with the prior art, the simple luggage wheel with shock-absorbing function provided by the utility model is provided with the shock-absorbing component, and the spring is used to push against the rotating ring and the push-up ring, so that when the wheel body is impacted, the push-up ring will slide along the rotating shaft, compress the spring, and play a role in shock absorption and buffering. At the same time, lubricating oil is applied between the rotating ring and the rotating shaft, and between the push-up ring and the movable end to further reduce the rotational friction between the metals, so that the rotation of the wheel body on the plane is more labor-saving, and will not be worn or aged due to long-term use. By setting the structure in which the fixed sleeve is inserted into the limiting sleeve, on the one hand, the movement range of the pulley is limited, and at the same time, the impact of wading and dust entering on the structure is reduced.

[0019] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0020] like Figures 1 to 4 As shown, it is a schematic diagram of the structure of the simple luggage wheel with shock absorption function provided by the utility model. The simple luggage wheel with shock absorption function comprises a mounting shell 10 mounted on the luggage, a pulley 20 arranged on one side of the mounting shell 10, and a shock-absorbing assembly 30 connecting the mounting shell 10 and the pulley 20. It can be imagined that the simple luggage wheel with shock absorption function also includes some other functional modules such as a pull rod assembly, a zipper assembly, etc., which are well known to those skilled in the art and will not be described in detail here.

[0021] The mounting shell 10 is made of plastic material and can be fixed to the bag by snapping with the mounting part at the bottom of the bag or by fasteners to achieve the installation of the pulley assembly. Accordingly, the mounting shell 10 is provided with a snap portion corresponding to the structure on the mounting part of the box or a fixing hole for the fastener to pass through. The mounting shell 10 is provided with a plug hole 11 for the shock absorber assembly 30 to be inserted, a plurality of reinforcing ribs 12 arranged around the plug hole 11, and a limiting sleeve 13 arranged outside the plug hole 11.

[0022] The insertion hole 11 is a circular through hole for inserting the shock-absorbing assembly 30. The reinforcing rib 12 is arranged around the insertion hole 11, extending in the axial direction of the insertion hole 11, and is located on the side of the mounting shell 10 away from the shock-absorbing assembly 30, so as to improve the structural strength of the insertion hole 11 and prevent it from being broken or damaged due to long-term stress during use. The limiting sleeve 13 is a cylindrical structure arranged around the insertion hole 11, and is located on the side of the insertion hole 11 close to the shock-absorbing assembly 30, so as to allow the relevant structures of the pulley 20 to be inserted.

[0023] The pulley 20 includes a connecting sleeve 21 connected to the shock absorbing assembly 30, and at least one wheel body 22 arranged on the connecting sleeve 21. A connecting hole 211 is provided at one end of the connecting sleeve 21, and a cylindrical fixing sleeve 212 is provided at the other end. The connecting hole 211 is a through hole, and the opening direction is consistent with the horizontal plane, so that at least one wheel body 22 can be fixed to the connecting sleeve 21 by inserting a fastener. The fixing sleeve 212 is a cylindrical structure with a hollow axis, which is inserted into the limiting sleeve 13 during assembly and is used to set the shock absorbing assembly 30. The bottom of the fixing sleeve 212 is open, and a plurality of reinforcing ribs are provided at the opening, and the aperture of the opening is smaller than the diameter of the barrel of the fixing sleeve 212, so as to facilitate the fixing of the shock absorbing assembly 30. The wheel body 22 is arranged on both sides of the connecting sleeve 21 through fasteners and is located at an end away from the mounting shell 10. It is a prior art in itself and should be well known to those skilled in the art. It is not the main content of the present invention, so it will not be described in detail here.

[0024] The shock-absorbing assembly 30 includes a rotating shaft 31 inserted into the connecting sleeve 21 , a rotating ring 32 sleeved on the rotating shaft 31 , a resisting ring 33 sleeved on the rotating shaft 31 , and a spring 34 sleeved on the rotating shaft 31 .

[0025] The rotating shaft 31 is made of metal material, one end of which passes through the socket 11, and the other end of which passes through the fixed sleeve 212 and extends out from the opening at the bottom. Both ends of the rotating shaft 31 are fixed by rivet technology. The rotating shaft 31 is provided with an annular abutting top 311 and a movable end 312. The abutting top 311 is a metal ring integrally formed with the rotating shaft 31, which is arranged close to the socket 11 during assembly, and is used to abut the rotating ring 32 and the spring 34. The movable end 312 is the end of the rotating shaft 31 away from the mounting shell 10, and the diameter of the movable end 312 is smaller than the main body diameter of the rotating shaft 31, so as to limit the movement path of the abutting ring 33.

[0026] The rotating ring 32, spring 34 and abutting ring 33 are sequentially sleeved on the rotating shaft 31 from the abutting top 311, and are all made of metal materials. The spring 34 is located between the rotating ring 32 and the abutting ring 33, and abuts on the rotating ring 32 and the abutting ring 33 respectively. The abutting ring 33 is located on the movable end 312, and the friction between the rotating ring 32 and the rotating shaft 31, and between the abutting ring 33 and the movable end 312 can be reduced by using metal polishing, applying lubricating oil, etc.

[0027] Compared with the prior art, the simple luggage wheel with shock-absorbing function provided by the utility model is provided with the shock-absorbing component 30, and the spring 34 is used to push against the rotating ring 32 and the push-up ring 33, so that when the wheel body 22 is impacted, the push-up ring 33 will slide along the rotating shaft 31, compress the spring 34, and play a role in shock absorption and buffering. At the same time, lubricating oil is applied between the rotating ring 32 and the rotating shaft 31, and between the push-up ring 33 and the movable end 312 to further reduce the rotational friction between the metals, so that the rotation of the wheel body 22 on the plane is more labor-saving, and will not be worn or aged due to long-term use. By setting the structure in which the fixed sleeve 212 is inserted into the limiting sleeve 13, on the one hand, the range of motion of the pulley 20 is limited, and at the same time, the impact of wading and dust entering on the structure is reduced.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
