Description

Technical Field

[0001] This utility model relates to the field of desk technology, and in particular to a foldable desk. Background Technology

[0002] Desks and chairs are a common type of teaching facility, designed to meet students' learning needs. Desks come in various types, including height-adjustable desks, solid wood desks, and plastic desks, but they all consist of a tabletop, drawers, a support frame, and legs. Two legs are vertically fixed to either side of the support frame, and the drawers are fixed to the support frame for storing bags, books, and other supplies. The tabletop is laid horizontally on the support frame and covers the drawers. While this type of desk has a relatively stable overall structure, classroom space limitations mean that the distance between adjacent desks is limited, and the chairs, when moved between desks, are somewhat cramped. Especially to accommodate students' nap time, some chairs are designed to unfold, resulting in a large extended length that requires more space.

[0003] As disclosed in announcement number CN220045300U, a desk and chair for convenient lunch breaks includes a table and a seat. The table includes table legs and a cabinet, with the cabinet angle-adjustable and mounted on the table legs. An adjustable footrest is provided below the cabinet. The seat includes a seat and a backrest, with the backrest angle-adjustable and mounted on the seat. A cushion that can be flipped up and placed on the cabinet behind the seat during lunch breaks is also provided on top of the backrest. This utility model of a desk and chair for convenient lunch breaks allows the cabinet angle to be adjusted and tilted forward during rest, increasing legroom. The backrest can be placed against the cabinet behind the table for stable support. The cushion allows the back to rest comfortably while seated, and the head to rest on during lunch breaks, greatly improving comfort.

[0004] However, while the above structure can theoretically solve the problem of students' lunch break, the placement of the tables and chairs and the space for movement are limited. In addition, there are significant differences in the height of individual students, and it is difficult for tall people with long legs to fully stretch out. Furthermore, the desks in the existing design are usually designed with legs supporting the sides, which means that no matter how the desktop is adjusted, it is always positioned horizontally above the student's body. As a result, students are prone to bumping into the desktop when they get up after lying down to sleep, and in severe cases, they may even fall, affecting the effectiveness of use. Utility Model Content

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0033] Combination Figures 1 to 9 As shown, this utility model discloses a foldable desk, including a desktop portion 100 and a frame portion 200. The frame portion 200 includes a frame base 220 and a support base 210, with the support base 210 located on one side of the frame base 220. A locking mechanism 300 is fitted between the desktop portion 200 and the support base 210. When the locking mechanism 300 is unlocked, the desktop portion 200 can be flipped and folded to the side of the support base 210, forming an open space 600 on one side of the support base 210. When the locking mechanism 300 is unlocked, the desktop portion 200 can be flipped and folded to the side of the support base 210, forming an open space 600 on the side of the support base 210. When locked, the desktop 200 is horizontally positioned above the support base 210. The optimized design of the table frame 200 structure, utilizing the support base 210 located on one side of the table frame base 220, creates an open space 600. After the desktop 100 and support base 210 are unlocked directly through the locking mechanism 300, the desktop 100 can be folded to the side of the support base 210, forming the open space 600. This frees up the space occupied by the desk, providing students with a good space for lunch break.

[0034] In conjunction with the above, the desktop section 100 includes a desktop body 110, which is typically a school desk. A desktop hinge seat 120 is provided on the desktop body 110, and a desktop mounting platform 211 is provided on the upper part of the support base 210. The desktop hinge seat 120 and the desktop mounting platform 211 are hinged together. Preferably, there are two desktop hinge seats 120, located on the front and rear sides near the support base 210, facilitating their connection with the desktop mounting platform 211. The desktop mounting platform 211 has a horizontal overhanging design, and it is typically horizontally parallel to the desktop body 110. Preferably, the hinge point between the desktop hinge seat 120 and the desktop mounting platform 211 is located at the intersection of the two, allowing the desktop body 110 to be laterally suspended on the inner wall of the support base 210 after being hinged and flipped by the desktop hinge seat 120, thus forming an effective folding space between them.

[0035] In combination with the above, the locking mechanism 300 includes a locking component 310 and a locking base 320. Either the locking component 310 or the locking base 320 is used to be installed in conjunction with the desktop body 110, and the other is used to be installed in conjunction with the desktop mounting platform 211.

[0036] In its specific structure, the locking assembly 310 includes a locking shaft 312, a lock housing 311, an unlocking part 316, and a reset part 314. The unlocking part 316 is used to move the locking shaft 312 to achieve the unlocking operation, which is convenient for users. Normally, when the locking mechanism 300 is in the locked state, the user pulls the unlocking part 316 to achieve the unlocking operation. One end of the locking shaft 312 is provided with a locking tongue 3121, and the other end cooperates with the reset part 314. The reset part 314 is used to reset the locking shaft 312. After the unlocking part 316 is unlocked, the user releases the unlocking part 316 to reset the locking shaft 312. The lock seat 320 is provided with a locking groove 321. The locking tongue 3121 is used to lock into the locking groove 321. The lock seat 320 is used to lock with the locking tongue 3121 to facilitate locking.

[0037] The unlocking part 316 typically includes a lever handle 3161 and a connecting arm 3162. The connecting arm 3162 extends along the outer side wall of the lock housing 311 on both sides, which facilitates its installation with the connecting shaft 313. The lever handle 3161 is convenient for the user to pull and operate.

[0038] In conjunction with the above, the lock housing 311 is provided with a travel slot 3113, which is shaped like a horizontal racetrack. The lock shaft 312 is provided with a connecting shaft 313, which is used to cooperate with the unlocking part 316. The unlocking part 316 can drive the lock shaft 312 to move along the travel slot 3113. The connecting shaft 313 passes through the travel slot 3113. With the drive of the unlocking part 316, the connecting shaft 313 can reciprocate along the travel direction of the travel slot 3113. In one alternative embodiment, the lock shaft 312 is provided with a lock hole, and the unlocking part 316 is provided with a connecting shaft. The connecting shaft cooperates with the lock hole to realize the synchronous fixation of the unlocking part 316 and the lock shaft 312, so that the unlocking part 316 can easily drive the lock shaft 312 to move.

[0039] In accordance with the above, the lock housing 311 has an inner cavity 3114 inside, which facilitates the reciprocating movement of the locking shaft 312. The two are in a sliding fit. The reset part 314 is located in the inner cavity 3114, usually inside the locking shaft 312. The locking shaft 312 is embedded in the inner cavity 3114. One end of the reset part 314 abuts against the lock housing end cap 3111 of the inner cavity 3114, and the other end abuts against the locking shaft 312. The latch 3121 can protrude out of the inner cavity 3114 or be received in the inner cavity 3114 as the locking shaft 312 moves. Under normal conditions without external force, the latch 3121 is normally in the inner cavity 3114. 21 protrudes from the inner cavity 3114 of the lock case, forming an outward convex structure. When the user pulls the unlocking part 316, the unlocking part 316 drives the locking shaft 312 to move into the inner cavity 3114 of the lock case, so that the latch 3121 can be accommodated in the inner cavity 3114 of the lock case. At this time, the reset part 314 is usually in a compressed state. When the user stops pulling the unlocking part 316, the reset part 314 achieves a reset push, causing the locking shaft 312 to move outward from the inner cavity 3114 of the lock case, so that the latch 3121 protrudes from the inner cavity 3114 of the lock case. The inner cavity 3114 of the lock case has a single-sided opening, and the opening is located at the end where the latch 3121 is located.

[0040] In combination with the above, the latch 3121 is provided with an arc-shaped self-locking surface 3122 and a limiting locking surface 3123, and a limiting locking rod 322 is provided on the upper part of the lock groove 321. The arc-shaped self-locking surface 3122 can abut against the limiting locking rod 322 and drive the lock shaft 312 to move towards the inner cavity 3114 of the lock case until the latch 3121 is reset by the reset part 314, so that the limiting locking surface 3123 and the limiting locking rod 322 achieve locking restriction. The structure of the latch 3121 is optimized, making the locking cooperation between the latch 3121 and the lock seat 320 more convenient and improving the convenience of locking and fixing.

[0041] In conjunction with the above, the reset part 314 is a reset spring, and also includes a guide shaft 315. The guide shaft 315 passes through the inner cavity of the reset spring. One end of the guide shaft 315 is fixedly engaged with the inner end of the lock shaft 312, and the other end corresponds to the through hole 3112 in the lock housing end cover 3111. The optimized design of the guide shaft 315 structure makes the reset of the reset spring more accurate and effective, and makes the reciprocating movement of the lock shaft 312 more stable and effective.

[0042] In one preferred embodiment, the locking component 310 is installed on the bottom surface of the desktop body 110 near the support base 210, and the lock seat 320 is installed on the desktop mounting platform 211. The desktop mounting platform 211 is also provided with an abutment 500, which is used to abut and limit the locking component 310. The abutment 500 is preferably designed to improve the positioning accuracy of the locking component 310 and increase the stability of locking.

[0043] In another alternative embodiment, the locking component 310 is mounted on the desktop mounting platform 211, and the lock seat 320 is mounted on the bottom surface of the desktop body 110 near the support base 210. The bottom surface of the desktop body 110 is also provided with an abutment 500, which is used to abut and limit the locking component 310. The abutment 500 is preferably designed to improve the positioning accuracy of the locking component 310 and increase the stability of locking.

[0044] In conjunction with the above, the lower part of the desktop mounting platform 211 is equipped with at least one support leg tube 212, preferably two support leg tubes 212, the upper ends of which are fixedly installed to the bottom ends of the support beam 2112 respectively; the lower part of the support leg tube 212 is used to cooperate with the table frame base 220 for installation.
