Description
Technical Field
[0001] This utility model relates to the field of dining table technology that is easy to fold and unfold, specifically a dining table that is easy to fold and unfold. Background Technology
[0002] As the core of family life, the dining table is not only an essential place for daily meals but also an important space for family communication and emotional connection; its necessity is self-evident. The design of a portable folding dining table greatly enhances the flexibility and adaptability of space utilization. In today's increasingly compact living spaces, its foldable feature provides ample tabletop space during meals to meet functional needs; during non-meal times, it can be easily folded away, instantly freeing up valuable floor space and effectively alleviating the cramped feeling of small apartments or open spaces, making the room appear more spacious and tidy. Especially for urban apartments, studios, or families requiring multifunctional areas, the portable folding dining table perfectly resolves the contradiction between limited space and functional needs, balancing practicality and space efficiency. It is an ideal choice for achieving a modern, minimalist, and efficient lifestyle, embodying both practical and emotional value.
[0003] The patent document with publication number "CN 221307593 U" mentions that "after long-term use, the connection points are prone to wear, which will make the stability of the tabletop decrease and easily cause safety hazards." The device uses an electric lifting rod to keep the tabletop in a fixed position and limit its movement, so that the tabletop can have good support. Multiple connecting rods are used to cooperate in support, which further improves the support strength. However, the connection method of the device makes it impossible to flexibly control the height of the tabletop. This may be inconvenient for short children, while the device being too low may be inconvenient for adults. It is not conducive to meeting different needs and occasions. Moreover, the universal wheels of the device do not provide a means of removal. Hiding them inside the fixed cabinet will further increase space consumption, making the device bulky and making it difficult to fold the attached connecting parts. Utility Model Content

[0025] Please see Figure 1-5 The present invention provides a technical solution: a dining table that is easy to fold and unfold, including a support 1 and a pillar 2 fixedly connected inside the support 1, a flexible support mechanism 3 is provided inside the support 1, and a convenient support mechanism 4 is provided on one side of the flexible support mechanism 3;
[0026] This mechanism is used to flexibly adjust the height of the table 305. This mechanism solves the problem of insufficient flexibility of traditional devices. The flexible support mechanism 3 includes a housing 301, which is fixedly connected to the lower surface of the support 1. A motor 302 is fixedly connected inside the housing 301. A screw 303 is fixedly connected to the output end of the motor 302. The screw 303 is rotatably connected inside the support 1. A slide 304 is threadedly connected to the outer wall of the screw 303. The slide 304 is slidably connected to the outer wall of the support column 2. A table 305 is rotatably connected to one side of the slide 304. Fastening platforms 306 are fixedly connected to the upper surfaces of both the table 305 and the slide 304. Fasteners 307 are inserted inside the right fastening platform 306. The fasteners 307 are threadedly connected to the inner wall of the left fastening platform 306. A sliding plate 308 is slidably connected inside the table 305. Bolts 309 are threadedly connected to both sides of the table 305.
[0027] Furthermore, the lower side of the bracket 1 has multiple square slots.
[0028] Furthermore, adjacent fastening tables 306 are set as a group, and multiple groups of fastening tables 306 are provided, with multiple groups of fastening tables 306 evenly distributed between the slide table 304 and the table 305.
[0029] Furthermore, a sliding cavity is provided inside the tabletop 305. Example
[0030] This mechanism provides additional support for the 305 tabletop, improving storage convenience and reducing space occupation. Please refer to [link / reference]. Figure 1-5Furthermore, in conjunction with Embodiment 1, the convenient support mechanism 4 includes a threaded seat 401, which is fixedly connected to the lower surface of the tabletop 305. A threaded post 402 is threadedly connected inside the threaded seat 401. A support cylinder 403 is fixedly connected to the lower end of the threaded post 402. A sliding plate 404 is slidably connected inside the support cylinder 403. A sliding rod 405 is fixedly connected to the lower end of the sliding plate 404. Multiple elastic support plates 406 are fixedly connected to the lower end of the support cylinder 403. The elastic support plates 406 are evenly distributed on the lower side of the support cylinder 403. A threaded wire 407 is fixedly connected to the outside of each elastic support plate 406. A nut 408 is threadedly connected to the outside of the threaded wire 407. The nut 408 is slidably connected to the outer wall of the sliding rod 405. A universal wheel 409 is fixedly connected to the lower end of the sliding rod 405. The connection between the elastic support plates 406, the threaded wire 407, and the nut 408 in this mechanism is a conventional fit, and its structural principle is the same as that of a telescopic clothes rod.
[0031] Furthermore, the slide plate 404 has multiple square slots inside, and the support cylinder 403 has a square limiting strip fixedly connected inside.
[0032] Furthermore, the nut 408 has a groove inside that mates with the elastic support plate 406 and the spiral line 407, so that the nut 408 can collect the elastic support plate 406 to provide a limit for the slide bar 405.
[0033] In actual operation, when this device is in use, the user pulls the table 305 out of the bracket 1 and engages it with the fastener 307 through the threaded connection with the fastening platform 306, thus supporting the table 305. Then, the user can loosen the sliding plate 308 from the clamping limit state by turning the bolt 309. The user can then pull out the sliding plate 308 and reposition it by rotating the bolt 309. At this point, both the table 305 and the sliding plate 308 are unfolded. Depending on the application, the user can drive the screw 303 via the motor 302. The screw 303 outputs using a threaded structure. The drive slide 304 moves, thereby adjusting the height of the table 305 and providing flexibility to the device. If the user needs to place heavy objects on the table 305, the user can connect the support cylinder 403 to the table 305 by rotating the threaded column 402. Then the user can pull out the slide rod 405 and make the caster wheel 409 contact the ground. Then the user can tighten the nut 408 to retract the multiple elastic support plates 406 inward. The friction between the inner wall of the elastic support plate 406 and the slide rod 405 allows the slide rod 405 to stably provide additional support to the table 305, making the device easy to store.
