Description

Technical Field

[0001] The present invention belongs to the technical field of learning utensils, and relates to a flip - type desk, in particular to a flip - top desk with a self - closing slot and its operation method. Background Art

[0002] A desk refers to a table for writing or reading, usually having a schoolbag compartment for storing schoolbags and textbooks. Many existing desks adopt a flip - top form to facilitate the access and search for schoolbags and textbooks.

[0003] Existing flips usually use a damping rod for support, and the damping rod needs to be embedded in the receiving groove of the schoolbag compartment during storage. The receiving groove on the existing schoolbag compartment is in an open state, which easily causes sundries to fall into the receiving groove. First, it pollutes the inside of the groove, bringing trouble for regular cleaning, and it is difficult to clean the dead corners at the parts installation positions. Second, the fallen sundries are easily stuck around the parts, resulting in poor swing of the damping rod, and even jamming the damping rod, affecting its rotation out or retraction.

[0004] In addition, the fixing screw holes on the existing schoolbag compartment are usually external holes, which affects the flatness of the outer wall of the schoolbag compartment and reduces the overall aesthetic appearance. Summary of the Invention

[0005] The purpose of the present invention is to address the above - mentioned problems in the existing technology and propose a flip - top desk with a self - closing slot that adds an automatically adjustable cover in the damping rod receiving groove to form an automatic cleaning measure and its operation method.

[0006] A flip - top desk with a self - closing slot includes support legs, on which a schoolbag compartment is fixedly arranged. The inner side of the schoolbag compartment has an open mouth, and an outward - turned mounting edge is arranged at the top mouth of the schoolbag compartment. An assembly interlayer is opened below the mounting edge. A desk panel covers the top mouth of the schoolbag compartment and the mounting edge. The desk panel has a flip - cover plate, the front edge of the flip - cover plate is a transition edge, a damping rod is arranged between the flip - cover plate and the schoolbag compartment, the bottom end of the damping rod extends into the assembly interlayer to form a hinge, the top end of the damping rod is hinged to the bottom surface of the flip - cover plate. A groove for accommodating the damping rod is arranged in the assembly interlayer, a lifting plate is slidably embedded in the groove, and an elastic lifting assembly is connected below the lifting plate and fixedly installed in the assembly interlayer.

[0007] In the above - mentioned flip - top desk with a self - closing slot, the elastic lifting assembly includes a positioning plate fixedly installed in the assembly interlayer by screws. A sleeve is recessed at the bottom of the positioning plate, the top surface of the sleeve is open, a spring is inserted into the sleeve, the upper part of the spring extends out of the sleeve in a free state, and the top end of the spring is fixedly connected to the bottom surface of the lifting plate.

[0008] In the above-mentioned flip-top desk with a self-closing slot, the desk panel further comprises a fixing plate, which is fixed to the front edge of the top opening of the backpack bucket by screws, and the front edge of the flip-top plate is hinged to the fixing plate.

[0009] In the above-mentioned flip-top desk with a self-closing slot, a rotating shaft is passed through the front edge of the flip-top plate, and adapter sleeves are fixed at both ends of the rear side of the fixed plate. The two ends of the rotating shaft extend into the two adapter sleeves one by one to form a rotating connection.

[0010] In the above-mentioned flip-top desk with a self-closing notch, the front edge of the flip-top plate and the rear edge of the fixed plate are connected via a plurality of hinges, so that the flip-top plate and the fixed plate form a flip connection.

[0011] In the above-mentioned flip-top desk with a self-closing slot, there is a mounting platform in the assembly interlayer, on which a first hinge seat is fixed by screws, and the bottom end of the damping rod is connected to the first hinge seat; a second hinge seat is fixed on the bottom surface of the flip plate by screws, and the top end of the damping rod is connected to the second hinge seat.

[0012] In the above-mentioned flip-top desk with a self-closing slot, there are two damping rods, which are symmetrically arranged on the two sides below the flip plate; two grooves are correspondingly arranged on the left and right, and the lifting plate and the elastic lifting assembly are arranged in each groove, and the damping rods correspond to the grooves one by one to form a storage fit.

[0013] In the above-mentioned flip-top desk with a self-closing notch, the interior of the backpack compartment has a stepped accommodating cavity, and a plurality of ventilation holes are evenly opened on the bottom wall of the accommodating cavity.

[0014] In the above-mentioned flip-top desk with a self-closing slot, the support leg includes a support leg and a support that are integrally connected, the support leg includes two symmetrically arranged bent legs, the support is a semi-frame frame, and the two bent legs are symmetrically fixed to the bottom of the semi-frame frame.

[0015] The function of the flip desk with self-closing slot includes the following:

[0016] 1) When the flip cover is rotated around its transition edge and flipped upward, the damping rod is simultaneously stretched and swings out of the groove of the assembly interlayer. As a result, the lifting plate is no longer pressed by the damping rod. Under the restoring elastic force of the spring below, the lifting plate rises freely until it is flush with the installation edge of the backpack bucket, while tightly sealing the notch of the cover groove. At this time, the lifting plate not only maintains the flatness of the installation edge, but also prevents debris from falling into the groove and causing pollution or affecting the storage of the damping rod;

[0017] 2) When the flip cover plate is rotated downward around its transfer edge to close the lower cover, the damping rod is synchronously shortened and gradually enters the groove of the assembly sandwich layer. When the damping rod is completely retracted into the groove, the damping rod presses the lifting plate, and the spring below the lifting plate is synchronously compressed and retracted into the sleeve. At this time, the lifting plate forms a supporting effect on the damping rod.

[0018] Compared with the prior art, the flip-top desk with self-closing grooves and its operation method have the following beneficial effects:

[0019] 1. By adding an automatically adjustable cover structure in the traditional damping rod storage groove, using the elastic supporting force and elastic reset force of the spring, and cooperating with the rotation in and out of the damping rod, the automatic lowering or rising operation is completed. It can not only provide a supporting effect for the damping rod storage, avoid the instability and fatigue caused by its being suspended in the air, but also automatically cover the groove opening when the damping rod rotates out, ensure flatness, and effectively prevent dirt caused by sundries falling in or the damping rod being blocked from being smoothly stored due to sundries. This structure does not require manual operation and is completed by its own elastic force, bringing convenience in use and being conducive to market promotion.

[0020] 2. All the traditional external screw holes are changed to screw holes inside the schoolbag pocket, thus ensuring the flatness of the appearance of the schoolbag pocket and improving the overall aesthetic degree of the appearance. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, through the lifting plate 8, the flatness of the installation edge is maintained, and sundries are prevented from falling into the groove to cause pollution or affect the storage of the damping rod 6;

[0040] 2). When the flip cover plate 4 is rotated downward around its transfer edge to close, the damping rod 6 is synchronously shortened and gradually enters the groove of the assembly sandwich layer. When the damping rod 6 is completely received in the groove, the damping rod 6 presses the lifting plate 8, and the spring 11 below the lifting plate 8 is synchronously compressed and retracted into the sleeve 10. At this time, the lifting plate 8 forms a supporting effect on the damping rod 6.

[0041] Compared with the prior art, the flip desk with a self-closing groove opening and its operation method have the following beneficial effects:

[0042] 1. By adding an automatically adjustable sealing structure in the traditional storage groove of the damping rod 6, using the elastic supporting force and elastic reset force of the spring 11, and cooperating with the rotation in and out of the damping rod 6, the automatic lowering or rising operation is completed. It can not only provide a supporting effect for the storage of the damping rod 6, avoid the instability and fatigue caused by its being suspended in the air, but also automatically seal the notch of the groove when the damping rod 6 rotates out, ensure the flatness, and effectively prevent the dirt caused by sundries falling in or the smooth storage of the damping rod 6 being blocked by sundries. This structure does not require manual operation and is all completed by its own elastic force, bringing convenience in use and being conducive to market promotion.
