[0001] The utility model relates to the technical field of luggage, in particular to a luggage with a small table structure. Background Technique

[0002] A luggage case, also known as a traveling case or a rolling suitcase, is a box used to carry items when going out. It is one type of luggage. Usually, a luggage case is used to place clothes, personal care products and souvenirs needed during a journey.

[0003] For example, the patent with the publication number CN201767241U discloses a luggage case, which can effectively solve the problem that the existing luggage case is easily deformed under pressure. A luggage case includes a case cover and a case body. The case cover includes four side plates and a top plate. The case body includes four side plates and a bottom plate. One side plate of the case cover is hinged to one side plate of the case body. A first reinforcing plate is provided in a circle on the four side plates of the case cover, and a second reinforcing plate is provided in a circle on the four side plates of the case body.

[0004] Through the above settings, the utility model in the prior art strengthens the strength of the side plates of the case cover and the case body, so that the luggage case is not easily deformed under pressure. However, the luggage case in the prior art solution has the following defects during operation:

[0005] The functions of the above-mentioned luggage case for transporting and storing items are too single to meet the needs of most people. Business people often travel on business and often waste a lot of time waiting for trains or flights. The luggage case should not only meet the needs of people for transporting items, but also consider the needs of temporary work or rest. Therefore, a luggage case with a small table structure is proposed. Content of the Utility Model

[0006] The utility model aims to provide a luggage case with a small table structure, which is mainly used to solve the technical problem that the existing technology has too single functions and does not provide the needs of rest or work for users.

[0007] To solve the above technical problems, the utility model provides the following technical solutions:

[0008] A luggage case with a small table structure includes a case body. Two rollers are symmetrically and fixedly connected to the bottom of the case body. A pull rod is slidably connected to the top of the case body. An installation groove is provided on the side wall of the case body. A table board is rotatably connected to the inner side wall of the installation groove. A telescopic component is fixedly connected to the lower side wall of the installation groove. Rectangular sliding grooves are symmetrically provided on the side wall of the installation groove at the lower end of the table board. A limiting component is slidably connected to the inner side wall of the rectangular sliding groove.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When in use, when the user needs to unfold the tabletop for work or rest, the tabletop can be made perpendicular to the box body by pulling the tabletop. During the rotation of the tabletop along the inner side wall of the installation groove, the telescopic component and the limit component work simultaneously, and the tabletop is always kept perpendicular to the box body through the limit component.

[0011] 2. Beneficial effects:

[0012] The prior art solves the technical problem that the suitcase is not easily deformed after being pressed by setting the strength of the box cover side plate and the box body side plate. However, the existing technology has the technical problems of being too single in function and not meeting the needs of providing rest or office for users. In this solution, the set limit component enables the tabletop to always be perpendicular to the box body, facilitating the user to work or rest on the top of the tabletop. The set telescopic component enables the tabletop to automatically retract into the installation groove after use, achieving the technical problem of convenience.

[0013] Preferably: The telescopic component includes a first mounting seat fixedly connected to the lower side wall of the installation groove. The inner side wall of the first mounting seat is rotatably connected to a sleeve. The inner side wall of the sleeve is slidably connected to a rod. The outer side wall of the end of the rod away from the sleeve is rotatably connected to a second mounting seat. The end of the second mounting seat is fixedly connected to the side of the tabletop close to the installation groove. When the tabletop rotates along the inner side wall of the installation groove, rotation occurs between the second mounting seat and the rod. As the tabletop rotates, the rod will slide outwards along the inner side wall of the sleeve until the rod is pulled to the maximum extent. At this time, the tabletop is perpendicular to the box body.

[0014] Preferably: The telescopic component further includes a first spring fixedly connected to the inner side wall of the sleeve. The other end of the first spring is fixedly connected to the end of the rod. When the rod slides outwards along the inner side wall of the sleeve, the first spring is stretched. After use, under the action of the stretched first spring, the tabletop can be quickly and automatically retracted into the installation groove, thus achieving the purpose of convenience.

[0015] Preferably: The length of the sleeve is much greater than the moving length of the rod to prevent the rod from detaching from the sleeve.

[0016] Preferably: The limit component includes a contact block slidably connected to the inner side wall of the rectangular chute. The end of the contact block is fixedly connected to a second spring. The other end of the second spring is fixedly connected to the inner side wall of the rectangular chute. During the rotation of the tabletop along the inner side wall of the installation groove, the side wall of the tabletop will contact the end of the contact block, and then the contact block will slide inwards along the inner side wall of the rectangular chute. At this time, the second spring is compressed. When the tabletop does not contact the contact block, the contact block is reset under the action of the compressed second spring, and the top of the contact block contacts the bottom of the tabletop, thereby preventing the tabletop from rotating back into the installation groove under the action of gravity.

[0017] Preferably, one side of the abutting block close to the tabletop is provided with an inclined surface, so that when the tabletop abuts against the abutting block, the abutting block can be retracted into the rectangular chute.

[0018] Preferably, an arc-shaped chute is formed in the outer side wall of the box body at the position of the rectangular chute, and the arc-shaped chute is communicated with the rectangular chute. A connecting rod is fixedly connected to the side wall of the abutting block, and the connecting rod is slidably connected to the inner side wall of the arc-shaped chute. After the tabletop is used up, by pushing the connecting rod, the connecting rod slides inside the arc-shaped chute. During the movement of the connecting rod, the abutting block is driven to slide into the rectangular chute, so that the tabletop is not restricted. Under the action of the stretched first spring, the tabletop quickly and automatically retracts into the installation groove, thus achieving the purpose of convenience. Description of the Drawings

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0025] Such as Figures 1-4As shown in the figure, a trolley case with a small table board structure includes a box body 2. Two rollers 4 are symmetrically and fixedly connected to the bottom of the box body 2. A pull rod 1 is slidably connected to the top of the box body 2. An installation groove 3 is formed in the side wall of the box body 2. A table board 5 is rotatably connected to the inner side wall of the installation groove 3. A telescopic assembly is fixedly connected to the lower side wall of the installation groove 3. When the table board 5 rotates along the inner side wall of the installation groove 3, rotation occurs between the second mounting seat 10 and the sleeve rod 9. As the table board 5 rotates, the sleeve rod 9 will slide outwards along the inner side wall of the sleeve 6. When the sleeve rod 9 slides outwards along the inner side wall of the sleeve 6, the first spring 8 is stretched until the sleeve rod 9 is pulled to the maximum limit. At this time, the table board 5 is perpendicular to the box body 2. After the table board 5 is used up, by pushing the connecting rod 15, the connecting rod 15 slides inside the arc-shaped chute 11. During the movement of the connecting rod 15, the abutting block 12 is driven to slide inside the rectangular chute 13, so that the table board 5 is not restricted. Under the action of stretching the first spring 8, the table board 5 quickly and automatically retracts into the installation groove 3, thus achieving the purpose of convenience. Rectangular chutes 13 are symmetrically formed in the side wall of the installation groove 3 at the lower end of the table board 5. A limiting assembly is slidably connected to the inner side wall of the rectangular chute 13. The limiting assembly includes an abutting block 12 slidably connected to the inner side wall of the rectangular chute 13. The end of the abutting block 12 is fixedly connected with a second spring 14. The other end of the second spring 14 is fixedly connected with the inner side wall of the rectangular chute 13. While the table board 5 rotates along the inner side wall of the installation groove 3, the side wall of the table board 5 will abut against the end of the abutting block 12, so that the abutting block 12 will slide inwards along the inner side wall of the rectangular chute 13. At this time, the second spring 14 is compressed. When the table board 5 is not in contact with the abutting block 12, the abutting block 12 is reset under the action of the compressed second spring 14, and the top of the abutting block 12 abuts against the bottom of the table board 5, thereby preventing the table board 5 from rotating back into the installation groove 3 under the action of gravity.

[0026] When the device is in use, when the user needs to unfold the table top 5 to work or rest, the user can pull the table top 5 to make it perpendicular to the box body 2. When the table top 5 rotates along the inner wall of the installation groove 3, the second mounting seat 10 and the sleeve rod 9 rotate. As the table top 5 rotates, the sleeve rod 9 will slide outward along the inner wall of the sleeve 6. When the sleeve rod 9 slides outward along the inner wall of the sleeve 6, the first spring 8 is stretched until the sleeve rod 9 is pulled to the maximum limit. At this time, the table top 5 is perpendicular to the box body 2. When the table top 5 rotates along the inner wall of the installation groove 3, the side wall of the table top 5 will conflict with the end of the interference block 12, and the interference block 12 will slide along the rectangular slide. The inner wall of the groove 13 slides inward, and the second spring 14 is compressed at this time. When the table top 5 is not in contact with the resistance block 12, the resistance block 12 is reset under the action of the compressed second spring 14, and the top of the resistance block 12 is in conflict with the bottom of the table top 5, thereby preventing the table top 5 from rotating back to the inside of the installation groove 3 under the action of gravity. When the table top 5 is used up, the connecting rod 15 is pushed to make the connecting rod 15 slide inside the arc-shaped slide groove 11. During the movement of the connecting rod 15, the resistance block 12 is driven to slide to the inside of the rectangular slide groove 13, and the table top 5 is not restricted. Under the action of the stretched first spring 8, the table top 5 is quickly and automatically retracted to the inside of the installation groove 3, thereby achieving the purpose of convenience.

[0027] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
