Description

Technical Field

[0001] This utility model belongs to the field of luggage technology, and in particular relates to a luggage with a detachable pull rod. Background Technology

[0002] Most suitcases on the market currently have their pull rods directly installed inside the side of the case to connect and secure the rod to the main body. Since the pull rod occupies space inside for storing luggage, the internal volume of the suitcase is reduced. At the same time, the rod divides the originally regular square space inside the case, making it difficult to stably place larger items, resulting in low utilization of the internal space. On the other hand, if the pull rod is placed directly on the outer surface of the suitcase, it will increase the overall volume of the suitcase, and the external structure will be irregular, resulting in poor aesthetics and instability when the suitcase is stacked horizontally.

Detailed Implementation

[0028] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of a detachable pull-rod type bag according to this utility model. The advantages and features of this utility model will become clearer from the following description and claims.

[0029] See Figures 1 to 3 This embodiment provides a bag with a detachable pull rod, including a bag body 1, a pull rod 2 and a buckle kit. The buckle kit can be used to realize a detachable connection between the bag body 1 and the pull rod 2.

[0030] Specifically, the buckle kit includes a male buckle assembly and a female buckle assembly, which must be used together. The male buckle assembly has a first male buckle 3 and a second male buckle 4, which are fixedly installed at the middle and bottom positions of the pull rod 2, respectively, along the length of the pull rod 2. The female buckle assembly has a connecting plate 5, which can be fixedly connected to the outer surface of the back of the bag body 1. The female buckle assembly also has a first female buckle 6 and a second female buckle 7. The first female buckle 6 is located at one end of the connecting plate 5 and is rotatably connected to the connecting plate 5, that is, the first female buckle 6 can rotate around the installation direction of the female buckle and is fixedly positioned at one end of the plane of the connecting plate 5. The second female buckle 7 is located at the other end of the connecting plate 5 and is fixedly connected to the connecting plate 5.

[0031] The first female fastener 6 and the second female fastener 7 each have a recessed portion 8 on the side facing the male fastener assembly. The first male fastener 3 and the second male fastener 4 each have a protrusion 9 on the side facing the female fastener assembly that matches the recessed portion 8 of the corresponding female fastener. During the docking and fixing process of the male fastener assembly and the female fastener assembly, the protrusions 9 of the first male fastener 3 and the second male fastener 4 can be simultaneously fitted into the recessed portions 8 of the first female fastener 6 and the second female fastener 7. At this time, the male fastener assembly and the female fastener assembly are fixed in relative position in the fastener installation direction.

[0032] Furthermore, the first female fastener 6 and the second female fastener 7 are each provided with a fastener opening 10 in the fastener plane extension direction. The fastener opening 10 connects the recessed portion 8 to the external space in the fastener plane extension direction, and the width of the fastener opening 10 is greater than the maximum cross-sectional dimension of the protrusion 9 of the first male fastener 3 and the second male fastener 4. That is, the protrusion 9 of the first male fastener 3 and the second male fastener 4 can move synchronously from the external space to the recessed portion 8 of the first female fastener 6 and the second female fastener 7 through the fastener opening 10, or move synchronously from the recessed portion 8 of the first female fastener 6 and the second female fastener 7 to the external space.

[0033] In summary, this embodiment provides a bag with a detachable pull rod. The bag body 1 and the pull rod 2 are detachably connected by a buckle assembly. Specifically, in the locked state, the protrusions 9 of the first male buckle 3 and the second male buckle 4 are respectively fitted into the recesses 8 of the first female buckle 6 and the second female buckle 7. In the buckle installation direction, the male buckle assembly and the female buckle assembly are fixed in relative position. At this time, the first female buckle 6 is rotated so that its buckle opening 10 faces opposite to the buckle opening 10 of the second female buckle 7, so that the male buckle assembly and the female buckle assembly also maintain a relative position lock in the extension direction of the pull rod 2, thereby achieving the fixing effect between the pull rod 2 and the bag body 1. In the unlocked state, the first female buckle 6 is rotated until its buckle opening 10 faces the same direction as the buckle opening 10 of the second female buckle 7. At this time, the protrusions 9 of the first male buckle 3 and the second male buckle 4 can be simultaneously disengaged or fitted into the recesses 8 of the first female buckle 6 and the second female buckle 7 through the buckle opening 10, thereby realizing the disassembly or assembly of the pull rod 2 and the bag body 1. This embodiment achieves a detachable connection between the bag body 1 and the pull rod 2, allowing the pull rod 2 to be fixed to the outer surface of the bag body 1 without occupying the internal space of the bag body 1, thereby increasing the carrying capacity of the bag body 1. Furthermore, it maintains the square shape of the internal carrying space of the bag body 1, facilitating stacking, storage, and stable transportation of large luggage. At the same time, based on the structural design of the male and female buckle components, the pull rod 2 can be easily separated from or fixed to the bag body 1 by rotating the first female buckle 6, enabling convenient disassembly or assembly of the pull rod 2. In scenarios where the pull rod 2 is not needed, it can be disassembled and stored separately without affecting the external shape and structure of the bag body 1.

[0034] The following will provide a more detailed description of the specific structure of a detachable pull rod luggage provided in this embodiment:

[0035] In this embodiment, the recessed portions 8 of the first female fastener 6 and the second female fastener 7 adopt a necking structure design. That is, the sidewalls of the recessed portions 8 of the first female fastener 6 and the second female fastener 7 gradually narrow from the bottom of the recessed portion 8 to the top opening of the recessed portion 8 along the installation direction of the female fastener. Moreover, the inner diameter of the top opening of the recessed portion 8 is smaller than the maximum cross-sectional size of the protrusions 9 of the first male fastener 3 and the second male fastener 4, respectively. This allows the protrusions 9 and the recessed portions 8 to be locked in position in the fastener installation direction through the interference fit between the top opening of the female fastener recessed portion 8 and the male fastener protrusion 9, making it difficult for them to come out easily.

[0036] Furthermore, in one embodiment, the protrusions 9 of the first male fastener 3 and the second male fastener 4 adopt a tapered tube structure design. That is, the cross-sectional dimensions of the protrusions 9 of the first male fastener 3 and the second male fastener 4 gradually increase from the end near the pull rod 2 to the end away from the pull rod 2 along the installation direction of the male fastener. The cross-sectional dimensions of the end away from the pull rod 2 are respectively larger than the inner diameter of the top opening of the recessed portion 8 of the first female fastener 6 and the second female fastener 7, and respectively smaller than the inner diameter of the bottom cavity of the recessed portion 8 of the first female fastener 6 and the second female fastener 7. The cross-sectional dimensions of the end near the pull rod 2 are respectively smaller than the inner diameter of the top opening of the recessed portion 8 of the first female fastener 6 and the second female fastener 7. Moreover, the length of the protrusions 9 of the first male fastener 3 and the second male fastener 4 is smaller than the depth of the recessed portion 8 of the first female fastener 6 and the second female fastener 7. This allows the protrusions 9 and the recessed portions 8 to be locked in position in the fastener installation direction, while being able to smoothly move relative to each other in the fastener plane extension direction, which facilitates the disassembly and assembly of the pull rod 2 and the bag body 1.

[0037] Furthermore, during the rotation of the first female fastener 6, the spatial position of the recessed portion 8 of the first female fastener 6 remains unchanged. That is, the first female fastener 6 takes the center point of its recessed portion 8 as its rotation center point, and the distance from the recessed portion 8 of the first female fastener 6 to the recessed portion 8 of the second female fastener 7 is the same as the distance from the protrusion 9 of the first male fastener 3 to the protrusion 9 of the second male fastener 4. This allows the male and female fastener components to achieve a tight fit when the pull rod 2 and the bag body 1 are in the locked state and during the unlocking process, thereby improving the connection tightness and stability of the pull rod 2 and the bag body 1 in the locked state.

[0038] In this embodiment, the back surface of the bag body 1 is provided with a plurality of threaded holes 11, and the connecting plate 5 is provided with a plurality of fixing holes corresponding to the threaded holes 11. A plurality of fixing screws are provided to pass through the fixing holes and be threadedly connected to the threaded holes 11, so as to realize the fixed connection between the bag body 1 and the connecting plate 5.

[0039] Furthermore, the back of the bag body 1 is also provided with a mounting groove 12, and a number of threaded holes 11 are provided in the mounting groove 12. The shape of the mounting groove 12 is adapted to the shape of the connecting plate 5, and the depth of the mounting groove 12 is the same as the thickness of the connecting plate 5. This ensures that when the connecting plate 5 is fixed to the bag body 1, the back of the bag body 1 is still a relatively flat plane, thereby achieving stable stacking of the bag body 1 when placed horizontally. Moreover, after removing the pull rod 2, there is no need to remove the female buckle assembly.

[0040] In this embodiment, the pull rod 2 is a single rod structure, and the pull rod 2 is provided with at least two telescopic rod sections. The extension and retraction of the pull rod 2 and the length locking can be realized by the pull rod button provided on the handle of the pull rod 2. Through extension and retraction adjustment, the bag body 1 can be conveniently dragged in different usage scenarios.

[0041] Further, see Figure 4When the pull rod 2 is in the retracted state, its length and width are both smaller than the length and width of the internal storage space of the bag body 1. This means that after the pull rod 2 is disassembled, it can be easily placed in the internal storage space of the bag body 1, reducing the overall space occupied by the bag when it is not in use.

[0042] Furthermore, see Figure 5 A rubber base is fitted at the bottom of the lever 2. After the lever 2 is disassembled, it can also be used independently. For example, the lever 2, which is a single rod structure, can be extended and locked to a suitable size, and then used as a cane, realizing the multi-functional applicability of the lever 2.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
