Description

Luggage caster structure

This creation belongs to the technical field of a kind of casters. Specifically, it refers to a luggage case caster structure. With the function of selectively stopping, it can prevent the luggage from sliding at will, and further can produce shock-absorbing effect, so that the luggage The box can be more stable when moving, and can reduce the phenomenon of damage to the luggage box due to moving impact, which can effectively extend its service life.

According to recent years, due to the development of lifestyles and means of transportation, the opportunities for people to go out to engage in business activities or travel have increased significantly. In order to facilitate people to carry clothing and personal belongings, luggage has become a must-have for people to travel. In the early days, luggage Only the handle is set up for people to lift and carry. However, because it is quite laborious and inconvenient to lift the suitcase and walk, usually the suitcase is provided with many casters on the bottom side, so that it can be easily moved or pulled.

In order to prevent the luggage box from arbitrarily slipping when it is parked (such as a platform, etc.), the wheel seat of the caster of the conventional luggage box is pivoted with a wheel body, and a trigger is pivoted on the wheel seat. The part has a contact pressure part corresponding to the wheel body, which can be pivoted by the contact pressure and pull part, so that the contact pressure part can contact with the wheel surface of the wheel body to produce a braking effect on the wheel body. However, the contact friction area between the contact pressing part of the above structure and the wheel surface of the wheel body is small, even forming a "point" contact, and the contact point is located on the side deviating from the rotation center of the wheel body, which is suitable for rotating in one direction. [For example, clockwise] the wheel body produces a braking effect, on the contrary, the wheel body rotates in the other direction [counterclockwise] It is not enough to produce an effective braking effect, and further improvement is needed.

Furthermore, because the aforementioned casters do not have a shock-absorbing function, when the towing suitcase is on a flat ground or encounters a depression, the collision between the casters and the ground will increase, and the weight of the suitcase will cause inconvenience on towing. Stable and even breakage of the casters. For this reason, the industry has developed a variety of luggage casters with shock-absorbing effects, such as my country Patent Publication No. M384570 "Shock-absorbing Tug", No. M533440 "Luggage Suspension Wheel" and so on. However, the shock-absorbing design of conventional casters is mainly based on the use of elastic bodies to directly bear the impact. This design can still achieve the shock-absorbing effect when the weight of the suitcase is light, but if the weight of the suitcase is heavier, then The elastic body may lose its shock-absorbing effect, causing the joint to be easily damaged by strong shocks, so it is not practical.

In other words, although the casters of the existing luggage have the functions of stopping and shock-absorbing, the structural design is not perfect, resulting in general problems such as stopping or ineffective shock-absorbing effect. Further improvements are needed. How to solve the aforementioned problems The problem is the subject that the industry is eager to think about, and it is also the subject that this creation wants to explore.

The reason is that the creator has many years of rich experience in design, development and actual production in the related industry, and has researched and improved the problems faced by the existing casters in use. After continuous efforts and trial production, they finally successfully developed a luggage case caster structure. It can effectively overcome the inconvenience and trouble caused by the existing poor practicability.

Therefore, the main purpose of this creation is to provide a luggage case caster structure, so that through a simple and reliable structure, the caster can have the effect of stopping stability and shock-absorbing effect, and can improve the safety and practicality of its use. sex.

In addition, the second main purpose of this creation is to provide a suitcase The caster structure can have a bidirectional stop function, and can be effectively inserted and positioned when stopping, which can prevent it from sliding arbitrarily when parked.

Furthermore, another main purpose of this creation is to provide a luggage case caster structure, which can provide a shock-absorbing effect in the direction of rotation, so that the impact force is effectively dispersed, greatly improving its shock-absorbing effect, and can reduce the impact caused by strong shocks. The phenomenon of damage can effectively extend the service life of the casters.

Based on this, this creation mainly uses the following technical means to specifically achieve the aforementioned goals and effects: it includes a coupling seat, a wheel seat, a wheel frame, at least one wheel body and a stop set;

The wheel base is pivotally pivoted at the bottom end of the coupling base, and the bottom end of the wheel base and the opposite end of the wheel frame respectively have at least one pivot lug that can be pivoted alternately, and the wheel base and the wheel frame There is a first elastic member supporting the opposite side in between;

The other wheel systems are pivoted on the middle section of the wheel frame by using a horizontal wheel shaft, and the side surfaces of the wheel bodies opposite to the wheel frame are formed with a series of teeth on the outer edge of the shaft. The embedding arc piece, and the stop set is formed with a sliding groove on the wheel frame, so that the embedding arc piece can be slidably arranged in the sliding groove, and at least one edge of the two sides of the embedding arc piece is formed with a pair of corresponding A second elastic member is provided between the engagement arc and the inner surface of the sliding groove of the wheel body, so that the engagement arc can selectively generate an engagement and stop function relative to the wheel body. The end of the wheel frame has a slot connecting the outside and the sliding slot, and the pulling member has a cam pivot lug pivoted in the slot, and the embedding arc has a corresponding cam pivot lug to push against Arc push noodles.

As a result, the luggage case caster structure of the present invention can selectively restrict the wheel bodies by using the interlocking arc pieces of the stop set, and cooperates with the design of the multi-teeth engagement that the interlocking arc pieces and the wheel bodies can be in surface contact. To make the wheels turn in any direction Both can be firmly inserted and stopped, and because the relative impact force between the wheel body and the wheel frame can be dispersed obliquely, the impact force can be effectively reduced, the shock-absorbing effect can be greatly improved, and the impact can be improved. Safety and practicality can further realize its economic benefits.

In addition, the present invention uses the following technical means to further achieve the aforementioned objectives and effects; such as:

The coupling seat has a downwardly hanging rotating shaft for the wheel seat to be pivoted and pivoted on the bottom surface of the coupling seat.

The opposite end of the wheel seat has a pivot lug, and the wheel frame has two pivot lugs to form a clamping slot for the pivot lugs of the wheel seat to be clamped, so that the two can be alternately overlapped and pivotally connected.

The wheel base and the wheel frame respectively form an opposite stop surface on the pivot radius of the pivot lug, so that the wheel frame is restricted to pivot within a specific angle range.

The opposite sides of the wheel seat and the wheel frame respectively have a guide rod extending obliquely, and the first elastic member is sleeved outside the guide rods.

The outer side of the wheel body different from the wheel frame is respectively covered with a wheel cover.
