Technical Field

[0001] This utility model relates to the field of luggage manufacturing technology, and more specifically, it relates to a high-pressure-bearing trolley case. Background Technology

[0002] When a suitcase is placed flat, the pressure is concentrated on the front. If the front of the suitcase cannot withstand sufficient pressure, it is prone to collapse and deformation, and in severe cases, it may break, resulting in poor overall performance. Therefore, this utility model proposes a high-pressure-bearing suitcase. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high-pressure trolley case with the characteristics of high pressure resistance and deformation resistance.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The utility model relates to a high-pressure bearing trolley case, which includes a front case and a rear case that are hinged to each other. The inner end face of the front case is provided with a number of longitudinal reinforcing ribs extending along the length direction and transverse reinforcing ribs extending along the width direction. At the intersection of any transverse reinforcing rib and all longitudinal reinforcing ribs or at the intersection of any longitudinal reinforcing rib and all transverse reinforcing ribs, a reinforcing column extending along the height direction is provided.

[0005] The present invention is further configured such that: a central hole is provided on the reinforcing column, a central column is slidably connected in the central hole, a pressure plate is provided at one end of the central column extending out of the central hole, an elastic element is sleeved on the central column with one end abutting against the central column and the other end abutting against the pressure plate, and a plurality of limiting holes extending axially are arranged around the outer periphery of the central hole, and limiting blocks are slidably connected in the limiting holes, and the limiting blocks are provided on the central column.

[0006] The present invention is further configured such that: a clearance hole is provided in the center of the central column, and a number of grooves equal to the number of limiting holes are arranged around the outer periphery of the clearance hole. Both the inner and outer ends of the grooves are connected to the outside. The groove openings are arranged facing away from the pressure plate. A spring piece integral with the central column is formed between two adjacent grooves. The limiting block is provided on the spring piece.

[0007] The present invention is further configured such that the end of the limiting block facing away from the pressure plate has a chamfered portion.

[0008] The present invention is further configured such that the elastic element is a compression spring.

[0009] In summary, this utility model has the following beneficial effects:

[0010] 1. Built-in interwoven reinforcing ribs enhance the bearing capacity in the end face direction, prevent deformation, and have strong compressive strength.

[0011] 2. Adding pressure plates that provide elastic compression creates a multi-support structure inside the box, further enhancing the end-face pressure-bearing capacity. Attached Figure Description

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0016] Example 1

[0017] See Figure 1 and Figure 2 As shown, the high-pressure bearing trolley case involved in this embodiment includes a front box 100 and a rear box (not shown) that are hinged to each other. The inner end face of the front box 100 is provided with a plurality of longitudinal reinforcing ribs 1 extending in the length direction and transverse reinforcing ribs 2 extending in the width direction. A reinforcing column 3 extending in the height direction is provided at the intersection of any transverse reinforcing rib 2 and all longitudinal reinforcing ribs 1 or at the intersection of any longitudinal reinforcing rib 1 and all transverse reinforcing ribs 2.

[0018] Furthermore, the reinforcing column 3 has a central hole 4, and a central column 5 is slidably connected in the central hole 4. A pressure plate 6 is provided at one end of the central column 5 that extends out of the central hole. An elastic element 7, which is a compression spring, is fitted on the central column 5, with one end abutting against the central column and the other end abutting against the pressure plate. Several limiting holes 8 extending axially are arranged around the outer periphery of the central hole 4. Limiting blocks 9 are slidably connected in the limiting holes 8 and are provided on the central column 5.

[0019] Furthermore, the center post 5 has a clearance hole 10 in the center, and the clearance hole 10 has grooves 11 with the same number as the limiting holes around its outer periphery. Both the inner and outer ends of the grooves 11 are connected to the outside. The groove openings of the grooves 11 are arranged facing away from the pressure plate 6. A spring piece 12 integrated with the center post is formed between two adjacent grooves 11. The limiting block 9 is provided on the spring piece 12.

[0020] Furthermore, the end of the limiting block 9 facing away from the pressure plate has a chamfered portion (not marked).

[0021] In this embodiment, when the suitcase is closed, the elastic pressure plate 6 presses against the items inside the suitcase, creating local support at that location. Combined with the longitudinal and transverse reinforcing ribs (including longitudinal reinforcing rib 1 and transverse reinforcing rib 2), the front suitcase 100 can form better pressure resistance and bearing capacity in the end face direction.

[0022] The combination of clearance hole 10, groove 11 and spring piece 12 facilitates the insertion of the center post 5, making assembly more convenient.

[0023] The chamfered portion serves as a sliding guide for the central post 5 during insertion.

[0024] The high-pressure-bearing trolley case involved in this utility model improves the end-face pressure-bearing capacity by incorporating internal interwoven reinforcing ribs, preventing deformation and providing strong pressure resistance; in addition, it is equipped with a pressure plate that provides elastic clamping, forming a multi-support structure inside the case, further enhancing the end-face pressure-bearing capacity. The overall function is complete and the practicality is strong.
