Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and in particular to a trolley luggage that can be effectively locked and fixed. Background Technology

[0002] In daily life, rolling suitcases are a core tool for storing clothes and belongings when traveling, and are widely used on public transportation such as buses, trains, and long-distance buses, as well as in crowded public places such as airports, high-speed rail stations, bus stations, and shopping malls. With the increase in travel frequency and the value of carried items, users' needs for the security and stability of suitcases when not in use are becoming increasingly prominent. However, current rolling suitcases on the market have significant shortcomings in locking and securing functions, making it difficult to meet the actual needs of use in public scenarios.

[0003] On public transportation such as buses and trains, frequent starts, stops, turns, and bumps during travel can cause unsecured rolling suitcases to slide and tip over due to inertia. This can lead to damage to the contents and potential safety hazards such as bumps and trips to other passengers. Furthermore, in public areas like waiting areas and rest areas at airports and high-speed rail stations, users often need to temporarily leave their luggage (e.g., to use the restroom or buy items). When this happens, the luggage is unattended, and existing suitcases only have combination locks or zipper locks to secure the door. These locks cannot be properly connected to fixed structures in public places (such as seat supports, railings, or luggage racks), making them easy targets for thieves and resulting in the loss of valuables and financial losses for users.

[0004] Further analysis of the existing structural design of rolling suitcases reveals that their core functions focus on suitcase storage, handle extension, and wheel movement. The handle structure serves only as an operational component for lifting and pushing the suitcase, without considering the need for locking and securing. Existing handles are mostly one-piece or separate structures, used only to assist in suitcase movement and lacking the function of locking to external objects. Furthermore, the suitcase as a whole lacks a locking mechanism for connection to fixed objects. Even if users carry additional locks, it is difficult to find suitable connection points to secure the suitcase, rendering locking impossible. Clearly, the existing technology requires improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a pull-rod suitcase that can be effectively locked and fixed, so as to solve one or more problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pull-rod suitcase capable of effective locking and fixing, comprising a main body consisting of a left and a right body hinged together, and a handle unit and a locking unit for locking the handle unit. The handle unit is composed of a left handle and a right handle with the same shape and structure. The left handle is respectively disposed on the front, upper and lower sides of the left body, and the right handle is correspondingly disposed on the front, upper and lower sides of the right body. The left handle and the right handle are combined to form a single handle unit. The locking unit is fixed to a fixed object.

[0007] In one embodiment of the present invention, the locking unit includes a lock seat and an elastic latch hinged to the lock seat, and the handle unit is locked between the elastic latch and the lock seat.

[0008] In one embodiment of the present invention, the main housing is provided with a latch, which is symmetrically distributed on the left and right sides of the handle unit.

[0009] In one embodiment of the present invention, the latch is provided with protective wings on its periphery.

[0010] In one embodiment of the present invention, a strip-shaped pad is provided on the rear side of the main housing, and the strip-shaped pad extends along the width direction of the main housing.

[0011] In one embodiment of the present invention, pads are distributed on the outer wall of the left compartment, and grooves are formed on the outer wall of the right compartment. The pads are embedded in the groove of another adjacent suitcase to form a fixed shape.

[0012] In one embodiment of the present invention, the main housing is provided with a pull rod mechanism, the pull rod mechanism including a pull rod body, a cover plate and a pull rod handle, the cover plate is fixed to the outside of the right housing, the pull rod body is slidably disposed between the cover plate and the right housing, and the pull rod handle is disposed on the top of the pull rod body.

[0013] In one embodiment of the present invention, a plurality of rollers are provided at the bottom of the main housing.

[0014] As described above, the trolley suitcase of this invention, which can be effectively locked and fixed, has the following beneficial effects: By setting a handle unit integrated with the main body and a matching locking unit, the stability and safety of the suitcase in public transportation and public places are significantly improved. When the suitcase is in a bus, train carriage, or airport waiting area, the user can quickly connect the locking unit to fixed objects such as seat brackets, handrails, and guardrails, so that the suitcase is reliably restrained by the handle unit and the fixed object, effectively preventing the suitcase from sliding due to vehicle start-stop, bumps, or crowds. This design not only avoids the risk of the suitcase blocking the aisle, colliding with other people's items, or tipping over, but also allows the user to ensure the stability of the luggage without continuous hand support, especially maintaining the position of the suitcase during sudden braking or sudden shaking of the train. In addition, the handle unit adopts a left-right split splicing structure, which provides a structural basis for the locking function, achieving a coordinated unity of portability and functionality, and fully meeting the actual needs of modern travel scenarios for the safe parking of luggage.

[0018] This utility model provides a pull-rod suitcase that can be effectively locked and fixed. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up, down, left, right," etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Please see Figures 1 to 3 This utility model provides a pull-rod suitcase capable of effective locking and fixing, including a main body 3 formed by hinged left body 1 and right body 2, and a handle unit 4 and a locking unit 5 for locking the handle unit 4. The handle unit 4 is composed of a left handle and a right handle with identical shapes and structures. The left handle is respectively located on the front, top, and bottom sides of the left body 1, and the right handle is correspondingly located on the front, top, and bottom sides of the right body 2. The left and right handles are combined to form a single handle unit 4. The locking unit 5 is fixed to a fixed object. Please refer to [link / reference]. Figure 2 When the rolling suitcase is placed horizontally on the ground, the handle unit 4 at the bottom of the main body 3 is locked and fixed by the locking unit 5. The locking unit 5 can be fixed in public transportation or public places, such as a special fixing frame in a subway car, a baggage fixing post in an airport waiting area, or a locking device under a train seat. At this time, the overall structure formed by the left and right handles is tightly engaged with the locking unit 5. Through the mechanical interlocking or electronic induction locking mechanism between the two, the displacement of the main body 3 in the horizontal and vertical directions can be effectively restricted. Even if there is a bump or sudden braking during the operation of public transportation, the suitcase can be prevented from sliding or tipping over, thus ensuring the safe placement of the luggage.

[0020] Please see Figure 3The locking unit 5 includes a lock base 51 and a resilient locking tongue 52 hinged to the lock base 51. The handle unit 4 is locked between the resilient locking tongue 52 and the lock base 51. When it is necessary to unlock the rolling suitcase from the locked state, the user only needs to press the unlock button on the side of the lock base 51. The button drives the resilient locking tongue 52 to rotate upward against its own elasticity through the internal linkage structure. At this time, the engagement between the resilient locking tongue 52 and the handle unit 4 is released, and the user can easily take the suitcase out of the locking unit 5. The bottom of the lock base 51 is provided with mounting holes that match the fixing devices of public transportation or public places. It can be quickly fixed by bolts, buckles or magnets. The surface of the lock base 51 is made of wear-resistant and rust-proof alloy material, which can adapt to the long-term use needs in different environments. The inner edge of the elastic locking tongue 52 is designed with anti-slip texture, which increases friction when it contacts the handle unit 4, further improving the stability of locking. At the same time, a buffer spring is built into its hinge, which can play a shock-absorbing and buffering role during locking and unlocking, preventing the parts from wearing out due to frequent operation.

[0021] Understandably, the resilient bolt 52 can also be locked to the lock base 51 via an external lock body. For example, a keyhole corresponding to the position of the resilient bolt 52 can be added to the side of the lock base 51. When the resilient bolt 52 is in the locked state, the shank of an external padlock or combination lock can be passed through the keyhole and the resilient bolt 52 to form a double locking structure, which can further improve security and prevent the resilient bolt 52 from being accidentally pressed to unlock when unattended. This is especially suitable for crowded public places such as airports and train stations. The installation position of the external lock body should be kept at a certain distance from the unlock button to avoid affecting the normal unlocking operation.

[0022] In this embodiment, the main body 3 is provided with a latch 6, which is symmetrically distributed on the left and right sides of the handle unit 4. A protective wing 7 is provided around the latch 6. The protective wing 7 is made of flexible rubber with rounded edges. When the rolling suitcase is subjected to external impact, it can buffer and protect the latch 6 and the surrounding suitcase structure, preventing the latch 6 from deforming or being damaged by direct impact. At the same time, the height of the protective wing 7 is slightly higher than the surface of the latch 6, which can effectively prevent dust, water stains, and other impurities from entering the gaps inside the latch 6, ensuring that the contact area between the latch 6 and the elastic locking tongue 52 remains clean for a long time, and ensuring smooth locking and unlocking operations.

[0023] A strip-shaped foot 31 is provided on the rear side of the main housing 3, extending along the width direction of the main housing 3. Optionally, the thickness of the strip-shaped foot 31 is 8-12mm, which allows the rear side of the main housing 3 to maintain a certain gap with the ground, preventing the bottom of the housing from directly contacting the damp ground or getting dirty. In addition, several rollers 34 are provided on the bottom of the main housing 3.

[0024] To enrich the usage scenarios and methods of the suitcases, pads 32 are distributed on the outer wall of the left suitcase 1, and grooves 33 are formed on the outer wall of the right suitcase 2. The pads 32 are embedded into the grooves 33 of the adjacent suitcase to form a fixed position. When the two suitcases are placed side by side, the cooperation between the pads 32 and the grooves 33 not only achieves lateral positioning, but also enhances the stability of the connection through elastic deformation, preventing relative sliding of the suitcases during transportation or storage. In addition, the gap between the pads 32 and the grooves 33 is controlled between 0.5-1mm, which ensures the convenience of assembly and effectively restricts the horizontal displacement of the suitcases. This is suitable for carrying multiple suitcases together when traveling with family, or for the centralized fixing of a batch of suitcases during logistics transportation, significantly improving the space utilization and usage flexibility of the suitcases.

[0025] Preferably, the main housing 3 is provided with a pull rod mechanism 8, which includes a pull rod body 81, a cover plate 82, and a pull rod handle 83. The cover plate 82 is fixed to the outside of the right housing 2, the pull rod body 81 is slidably disposed between the cover plate 82 and the right housing 2, and the pull rod handle 83 is disposed on the top of the pull rod body 81. More specifically, several positioning holes are symmetrically distributed on both sides of the pull rod body 81, and elastic buckles are provided at corresponding positions on the inner side of the cover plate 82. When the pull rod body 81 is extended to different heights, the elastic buckles can be inserted into the positioning holes to achieve height locking, meeting the usage needs of users of different heights.

[0026] In summary, the present invention provides a trolley suitcase that can be effectively locked and fixed. Through the unique combination structure of the handle unit 4 and the locking unit 5, it significantly solves the problem that existing trolley suitcases cannot be effectively locked and fixed in public transportation and public places, and has many outstanding beneficial effects.

[0027] From the perspective of structural fit and locking effectiveness, the handle unit 4 consists of a left handle and a right handle with the same shape and structure. The left handle is positioned on the front, top, and bottom of the left compartment 1, and the right handle is positioned on the front, top, and bottom of the right compartment 2. The two are combined to form a single-structure handle unit 4. This multi-positional split-combination design not only retains the basic functions of traditional handles for lifting and pushing the compartment, but also provides a stable and compatible connection point for the locking unit 5. When the locking unit 5 is fixed to a fixed object in public transportation (such as seat supports and luggage racks on buses and trains) or public places (such as railings in waiting areas of airports and high-speed rail stations, and fixed structures in shopping mall rest areas), it forms a firm lock with the assembled handle unit 4. This avoids the problem of existing suitcases being difficult to lock or easily loosening after locking due to the lack of compatible connection points, ensuring that the compartment cannot be moved at will when locked, and effectively improving the reliability of locking.

[0028] From the perspective of improving safety and practicality in various usage scenarios, on mobile transportation such as buses and trains, when the vehicle starts, stops, turns, or experiences bumps, the locking unit 5 and handle unit 4 work together to securely fix the suitcase to a fixed object, preventing it from sliding or tipping over due to inertia. This avoids damage to the contents of the suitcase due to collisions and eliminates safety hazards such as bumps and trips to surrounding passengers caused by the suitcase sliding. In public areas such as waiting areas and rest areas at airports and high-speed rail stations, when users temporarily leave their suitcases (such as to go to the restroom or to buy items), the locking unit 5 and handle unit 4 can securely connect the suitcase to a fixed object. Compared to existing suitcases that rely solely on a combination lock or zipper lock for anti-theft, this method fundamentally prevents the entire suitcase from being stolen, significantly reducing the risk of losing valuables inside and providing users with more comprehensive security.

[0029] Furthermore, no complex modifications to the main body 3 of the rolling suitcase are required. The separate left and right handles and their corresponding assembly structure are simple and easy to manufacture and assemble. The locking unit 5 can also be adapted to various common fixing structures in public scenes, eliminating the need for users to carry additional special fixing accessories. While ensuring the locking function, it also takes into account the portability and ease of use of the suitcase, meeting users' locking needs in different public scenes and further improving the overall user experience of the rolling suitcase. This aligns with the current trend of users demanding both "secure fixing" and "convenient use" in their suitcases, and has broad practical application value. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial utilization value.

[0030] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
