Description

Anti-falling draw-bar suitcase

Technical Field

The utility model relates to the technical field of draw-bar boxes, in particular to an anti-falling draw-bar box.

Background

In the travel and luggage fields, draw-bar boxes are a common luggage carrier. As the demands of people for travel increase, protection and improvement of durability and protection performance of draw-bar boxes are becoming a focus of attention. The conventional trolley case has some disadvantages in providing basic protection functions, and more advanced technology is required to solve the following problems:

The protection performance is poor: the conventional draw-bar box lacks sufficient protection performance in the face of external factors such as impact, drop and bump. They often fail to absorb and disperse the impact force, resulting in a case that is vulnerable.

Poor durability: the shell structure of the traditional draw-bar box is generally weak, and the problems of breakage, deformation and the like are easy to occur in long-time use and travel. This reduces the life of the trolley case and may result in ineffective protection of the interior items.

Pressure imbalance: conventional draw-bar boxes are not generally designed for an even distribution of impact forces and gravity. When the box body is impacted or subjected to heavy objects, certain parts are subjected to larger pressure, and damage or deformation is easy to cause.

In general, the conventional draw-bar box has disadvantages in terms of protection performance, stability, durability, pressure distribution, and the like. In order to solve the problems, the new generation of anti-falling draw-bar luggage combines innovative designs and technologies, and has more excellent protection performance and use experience.

Therefore, the technical proposal provides the anti-falling draw-bar suitcase to solve the problems.

Referring to fig. 1-6 of the specification, the utility model provides an anti-falling draw-bar box, wherein a box body 1 of the anti-falling draw-bar box is made of a firm and durable material and has proper rigidity and strength.

The front and back corners of each case 1 are provided with an outer protection assembly 5 including an outer protection frame 51, corner protection arms 52, a buffer assembly 53 and limit guide teeth 54.

The outer protective frame 51 is integrally located outside the edges of the front and rear sides of the case 1, and provides an additional protective layer.

The corner protection arms 52 are located at four corner ends of the inner side end surface of the outer protection frame 51 and are located at the outer side of the side edge of the case 1, so as to provide a better corner protection effect.

The buffer components 53 are uniformly distributed on the inner side end surface of the outer protective frame 51 and are matched with a plurality of plug holes 4 arranged on the same side surface of the box body 1, and the structures of the guide plug posts 531 and the buffer springs 532 are adopted.

The elastic protection plate 6 is installed in the outer protection frame 51 and between the corner protection arms 52 of the upper and lower ends, and has a plurality of diamond-shaped lightening holes 61 uniformly distributed to provide a shock absorbing and buffering effect.

The outer protective frame 51 and the corner protective arms 52 are made of a fluororubber material which is wear-resistant, temperature-resistant and corrosion-resistant, and have good impact resistance and durability.

The pull rod storage box 2 is arranged on the plate surface of the front side elastic protection plate 6 and used for storing and protecting the pull rod 3, and the pull rod 3 is fixed inside the pull rod storage box 2 in a sliding clamping manner.

The center of the front end of the inner side surface of the corner protection arm 52 is provided with a limit guide tooth 54, and the corners of the upper, lower, left and right box walls of the box body 1 are respectively provided with two limit guide grooves 7 which are symmetrically distributed, so that the clamping and sliding of the corner protection arm 52 and the limit guide grooves 7 are realized, and the outer protection component 5 is prevented from being separated from the box body 1.

Protection principle when box 1 falls down:

When the box body 1 falls down, the outer protection component 5 plays an important role in protection. The design structure of the outer protection component 5 can absorb and disperse impact force generated by falling, so that the influence on the articles in the box body 1 is reduced, and the damage to the box body caused by the outside is reduced. The specific protection principle is as follows:

Outer protective frame 51: the outer protective frame 51 serves as a protective layer on the outside of the edge of the case 1, and is first impacted when the case falls. The solid structure can bear the impact force, and the impact force is transferred to other parts through the integral layout and assembly mode, so that the direct impact on the articles in the box body is reduced.

Corner guard arm 52: the corner protection arms 52 are located at four corner ends of the inner side end surface of the outer protection frame 51, and they function to protect the corners of the case. When the case is tilted or impacted, the corner guard arms 52 can absorb and disperse the impact force, reduce the impact on the corners of the case, and reduce the risk of damage to the corners.

Buffer assembly 53: the buffer assembly 53 is composed of a guide insertion post 531 and a buffer spring 532. The guiding plug-in column 531 is connected with the case 1 through the plug-in hole 4 and is fixed on the inner side end surface of the outer protection frame 51. When the case falls down, the buffer spring 532 can absorb and buffer the impact force, reducing the degree to which the impact force is transmitted to the articles inside the case 1.

In summary, when the case 1 falls, the outer protection component 5 can absorb and disperse the impact force through the structures and characteristics of the outer protection frame 51, the corner protection arms 52 and the buffer component 53, so as to reduce the impact and damage to the articles inside the case, and provide effective protection.

When encountering the case 1 and being bumped, the elastic protection plate 6 exerts the following protection principle:

elastic properties: the elastic protection plate 6 is made of a high-elasticity plate and has certain softness and compression capability. When the case collides, the elastic protection plate 6 can absorb and buffer impact force through its elastic characteristic, reducing direct impact to the case and internal articles.

Damping and buffering: the elastic protection plate 6 is uniformly provided with a plurality of weight-reducing holes 61, and the existence of the weight-reducing holes 61 can increase the flexibility and elasticity of the protection plate, thereby further providing the effects of shock absorption and buffering. The lightening holes 61 can play a role of dissipating impact energy and relieving impact strength when the case is bumped.
