Description

Technical Field

[0001] The invention belongs to the technical field of desks and relates to a flippable desk. Background Art

[0002] Due to the limited space in the classroom, students' desks usually need to have good storage functions. When lying down for lunch break, the existing desks and chairs are usually tilted forward to make room for lunch break, and the backs of the chairs are folded back and placed on the desk for lunch break, so as to achieve lying down and sleeping. The above structure requires a large front and back space for lying down, and the angle for lying down is not comfortable enough, resulting in insufficient space and poor comfort for students when lying down. The existing desks with single-sided legs can make room on the other side for students to enter and exit, but they are located under the desk when lying down, which will produce a sense of depression when sleeping, and easily cause students to feel uncomfortable.

[0003] The folding mechanism of the table top sub-plate of the table is disclosed in the Chinese patent application [CN216165909U], which comprises a folding arm, a limiting block, a folding bolt and a fixing seat, wherein the fixing seat comprises a rear plate and two side plates, the rear plate of the fixing seat is fixedly mounted on the outer side of the fixing frame at the bottom of the table, the folding arm is fixed to the bottom of the table top sub-plate, and the rear end of the folding arm is inserted between the two side plates of the fixing seat, a U-shaped long groove is provided at the rear end of the folding arm, a round hole is provided at the rear end of the U-shaped long groove, the folding bolt passes through the U-shaped long groove of the folding arm horizontally, and its two ends are fixed to the two side plates of the fixing seat, and the cross-section of the column of the folding bolt is oval, and its two parallel surfaces cooperate with the U-shaped long groove of the folding arm, the limiting block is arranged on the rear part of the fixing seat, the limiting block has a slot, and the rear end of the folding arm has a protrusion that cooperates with the slot of the limiting block.

[0004] When the desktop sub-plate of the above structure is in use, the protrusion on the flip arm is inserted into the slot on the limit block, so that the two parallel surfaces of the flip bolt cooperate with the U-shaped long slot of the flip arm, thereby realizing the limitation of the flip arm. The limitation only adopts the surface-to-surface clamping cooperation. For the desktop sub-plate that will not be used for a long time, its stability can be guaranteed. However, for student desks, more books need to be stacked on the desk top during normal use, and during the study process, the student's arms will be placed on the desk top, so that the desk top needs higher stability when in use to avoid shaking of the desk top, which affects the normal use of the desk top. However, the above structure does not have high stability, which affects the normal use of the desk with single-sided legs. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and to propose a flippable desk. The technical problem to be solved by the present invention is: how to solve the problem that the existing desk with single-sided legs that can flip the table top has poor stability during normal use.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A flip desk comprises a table top and at least one table leg, wherein one side of the table top is connected to the upper end of the table leg, and the other side of the table top is suspended. The desk is characterized in that the upper end of the table leg has a tubular support bar which is arranged inwardly along the transverse direction, the outer end of the support bar has a plug-in hole opened along the transverse direction, and the upper side surface of the inner end has a clearance opening, a sliding rod which is arranged along the transverse direction is connected to the table top, and the outer end of the sliding rod can be inserted and fixed in the plug-in hole; a strip hole which is arranged along the transverse direction is opened on the sliding rod, and a support shaft is fixed to the inner end of the support bar, the sliding rod is inserted into the strip hole through the support shaft and is hinged to the support bar, and the sliding rod can also slide laterally to make its outer end fall out of the plug-in hole.

[0008] During normal use, the outer end of the sliding rod is inserted and fixed in the plug-in hole of the support strip, and the vertical and horizontal positioning between the sliding rod and the support strip are realized by embedding the end of the sliding rod in the plug-in hole of the support strip horizontally, thereby realizing a stable connection between the sliding rod and the support strip during normal use. When a nap is needed or the desk is to be stored, the sliding rod can also slide horizontally along the strip hole to make the outer end of the sliding rod escape from the plug-in hole, and the sliding rod can rotate downward around the support axis and make the table top vertically arranged, thereby realizing the table top being close to the inner side of the table leg. At this time, the chair part can be placed on the side of the desk where no table legs are set, and with the help of part of the aisle space, lying down and sleeping can be realized without the need for the front and rear tables to give way and cooperate, thereby improving the space utilization rate of the desk when lying down and sleeping. The cooperation between the plug-in hole on the strip and the outer end of the sliding rod adopts a plug-in and fixing method to realize the vertical and horizontal positioning of the sliding rod. When the table board needs to be flipped, the giving way is set so that when the outer end of the sliding rod slides laterally out of the plug-in hole, the giving way will make way for the sliding rod, so that the sliding rod rotates around the support shaft. The cooperation between the strip hole and the support shaft avoids the problem of a large stroke of the sliding rod when it moves laterally. The strip hole and the support shaft realize support for the middle part of the sliding rod. The connection between the plug-in hole and the outer end of the sliding rod can realize the support of the outer end of the sliding rod by the support strip, thereby realizing multi-point support for the table board, improving the pressure-bearing capacity and practical stability of the table board, so that the desk with single-sided legs has a folding function without affecting the stability of the desk with single-sided legs in normal use.

[0009] In actual use, two desks with vertically arranged desks can be inserted into each other after flipping, thereby reducing storage space, saving storage space when the desks are not in use, and facilitating storage. The present application adopts horizontal sliding and flipping, and can also prevent the desk from interfering with the table legs during the flipping process when a large desk is connected under the desk, and also improve the stability of the flip structure when there is a large storage space.

[0010] In actual use, the strip-shaped holes can also be opened on the support strips, and the support shafts can be fixed on the sliding rods, so as to realize the sliding and flipping structure.

[0011] In the above-mentioned flippable desk, a clearance gap is formed between the lower wall of the desk board and the upper wall of the outer end of the sliding rod.

[0012] The setting of the clearance gap ensures that when the sliding rod is inserted into the support bar, there is a clearance gap between the table top and the sliding rod for the upper wall of the support bar to be inserted, and also allows the upper wall of the support bar to be located between the table top and the sliding rod. Through the mutually plug-in structure, the stability of the table top during normal use is further improved.

[0013] In the above-mentioned flippable desk, the sliding rod is U-shaped, the sliding rod is fixed around the circumference of the table top, the above-mentioned two support strips are provided on the table legs along the front-to-back direction, and the two outer ends of the sliding rod can be inserted into the corresponding support strips.

[0014] The shape of the sliding rod can provide stable support for the table top, making the connection between the table top and the table legs more stable, and through the setting of a sliding rod, it can be connected with two support bars, making installation more convenient.

[0015] During the production process, for cost considerations, sliding rods may be provided at the front and rear ends of the table top respectively, so as to realize the sliding and flipping functions.

[0016] In the above-mentioned flip desk, the lower end of the table top is connected to a table drawer, the table legs are provided with two and distributed along the front-to-back direction, the upper ends of the two table legs are connected by a connecting rod, the table legs can be vertically extended and retracted, and the connecting rod is always located on the outside of the table drawer.

[0017] Since it is a desk with single-sided legs, when the legs are extended or retracted vertically, you only need to pull the upper end of one of the legs to move vertically, and the connecting rod can drive the other leg to move synchronously. In order not to occupy the aisle space, the connecting rod is directly set between the two legs. Therefore, while ensuring that the desk drawer has a large storage space, the desk drawer can avoid the connecting rod and the legs by sliding horizontally first, making the flipping more stable.

[0018] In the above-mentioned flippable desk, a limiting opening is provided on the lower side of the inner end of the support bar, and the sliding rod can be partially located in the limiting opening after flipping and the outer wall of the sliding rod is laterally against the wall of the limiting opening.

[0019] By setting the limiting opening, after the table top is rotated around the supporting shaft by the sliding rod, the outer wall of the sliding rod will laterally abut against the wall of the limiting opening, thereby realizing the lateral limitation of the table top after flipping, so that the table top can be stably set vertically, thereby improving the stability of positioning after flipping.

[0020] In the above-mentioned flippable desk, the outer end surface of the sliding rod is a yielding surface which is inclined downward and outwardly arranged, and when the support shaft abuts against the outer end of the strip hole, the yielding surface is located outside the plug hole.

[0021] The setting of the giving way surface can prevent the sliding rod from being moved out of the plug-in hole and then being guided and given way when flipping, thereby making the flipping smoother and more stable.

[0022] In the above-mentioned flippable desk, a fastener is connected to the support bar, a positioning hole is provided on the sliding rod, and the fastener is plugged into the positioning hole when the outer end of the sliding rod is inserted into the plug hole.

[0023] With the arrangement of this structure, the fastener can be inserted into the positioning hole to realize the positioning of the outer end of the sliding rod and the support bar, and the plug-in limiting method is adopted to realize the stable limiting of the sliding rod and the support bar, thereby improving the convenience and stability of positioning.

[0024] In the above-mentioned flippable desk, a fastener is connected to the support bar, and the fastener passes through the support bar and is threadedly connected to the support bar.

[0025] The fastener passes through the support bar and is threadedly connected to the support bar, thereby pressing the side wall of the sliding rod against the hole wall of the plug-in hole to achieve compression positioning. The compression positioning method is used to achieve rapid positioning of the sliding rod, thereby improving the convenience and stability of positioning.

[0026] In the above-mentioned flippable desk, the fastener is located on the side wall or the bottom wall of the outer end of the support bar, and the stem portion of the fastener is located outside the support bar.

[0027] The fastener can be located on the outer side wall or bottom wall of the support bar, with its rod portion located outside the support bar, so that the fastener can also be used for hooking. When located on the side wall, it is convenient for students to adjust. When located on the bottom wall, it can prevent students from getting hung up when using it, thereby improving safety.

[0028] In the above-mentioned flippable desk, a storage tray is provided between the lower ends of the two table legs.

[0029] The storage tray can also increase the storage space of the desk without affecting the aisle space, making it easier for students to use.

[0030] Compared with the prior art, the reversible desk has the following advantages:

[0031] 1. Through the setting of the yielding opening, when the outer end of the sliding rod slides out of the plug-in hole laterally, the yielding opening gives way to the sliding rod, so that the sliding rod rotates around the support shaft. Through the setting of the support shaft and the sliding rod plugged in the plug-in hole, the inner and outer ends of the support bar provide support for the sliding rod when the desk is in normal use, thereby realizing multi-point support for the table board, improving the pressure-bearing capacity and stability of the table board, and allowing the desk with single-sided legs to have a folding function without affecting the stability of the desk with single-sided legs in normal use.

[0032] 2. Since it is a desk with single-sided legs, when the legs are extended or retracted vertically, you only need to pull the upper end of one of the legs to move vertically, and the connecting rod can drive the other leg to move synchronously. In order not to occupy the aisle space, the connecting rod is directly set between the two legs. Therefore, while ensuring that the desk drawer has a large storage space, the desk drawer can avoid the connecting rod and the legs by sliding horizontally first, making the flipping more stable.
