Description

Technical Field

[0001] The utility model belongs to the technical field of desks and relates to a storage desk. Background Art

[0002] Existing students have a lot of schoolwork, so they have a lot of study books, extracurricular books and school supplies. Generally, some of the books are placed on the table and some are placed in the book drawer under the table. However, in order to improve the comfort of students during lunch break, it is generally necessary to use the space under the table drawer for students to place their legs, which leads to the small size of the table drawer and inability to place many books, making it inconvenient for students to place their books. Especially for junior and senior high school students, when the book drawer is not big enough, the books are usually piled on the table, which affects the use space of the table and causes inconvenience for students.

[0003] Therefore, existing desks usually adopt a multifunctional desk such as the Chinese patent application [Authorization Announcement No.: CN202146068U], which includes a desktop, a desk hole fixedly connected to the front end of the desktop, and supporting legs fixedly connected to the four corners of the bottom of the desk hole. The desktop is divided into two parts, left and right, and the rear end is connected to the bottom of the desk hole by a snap-fit. A foldable bookend is provided in the front right side of the desktop, a sandwich net is provided on one side of the supporting leg, a cup holder is provided on the other side, and a pedal is provided at the bottom.

[0004] Although the above structure is achieved by arranging a sandwich net on one side of the supporting leg, the sandwich net is a mesh with limited load-bearing capacity and cannot hold too many things. Only some sundries can be placed in the sandwich net, but books cannot be placed in the sandwich net. Therefore, the above desk usually places books on the pedal, but the pedal occupies the space under the table hole, which makes it inconvenient for students to place their legs, and the setting of the pedal also makes it inconvenient to clean the desk. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to propose a storage desk. The technical problem to be solved by the utility model is: how to solve the problem that students have difficulty storing books and the storage parts have poor installation stability.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A storage desk comprises a table top, two table feet and two supporting legs connected to the table top, characterized in that the lower ends of the two supporting legs are fixed to one of the table feet and are respectively arranged near the front and rear ends of the table foot. The storage desk also comprises a longitudinal rod, a transverse rod and a storage tray with a placement opening, the longitudinal rod and the transverse rod are arranged at the same height, the longitudinal rod is fixed between the two supporting legs, one end of the transverse rod is connected to the longitudinal rod or one of the supporting legs, and the other end is connected to the other table foot, the storage tray is located between the two supporting legs, and the bottom of the storage tray is arranged on the longitudinal rod and the transverse rod.

[0008] Working principle: two supporting legs, two table feet, a longitudinal rod and a transverse rod are arranged under the table board, the lower ends of the two supporting legs are connected to the lower end of one of the table feet, and the supporting legs are respectively arranged close to the front and rear ends of the table feet, and the upper ends of the supporting legs are connected to the table board. The larger distance between the supporting legs makes the space between the supporting legs larger, which is convenient for placing the storage tray between the two supporting legs, and is fixed between the two supporting legs by the longitudinal rod, and the transverse rod is connected to the longitudinal rod or one of the supporting legs, and the other end is connected to the other table foot, thereby realizing stable support for the supporting legs and the table board. By adding a storage tray, the bottom of the storage tray is arranged on the longitudinal rod and the transverse rod, and the storage tray is located between the two supporting legs, occupying more of the space between the supporting legs, and also The space under the table board near the supporting legs is partially used, and the storage space of the desk is increased while reducing the space under the table board. The storage tray not only realizes three-point support through the longitudinal rod and the cross rod at the bottom, but also can realize the limit in the front and rear directions through the supporting legs, and further enhances the strength of the supporting legs and other components, and improves the stability of the lower part of the entire desk. At this time, the longitudinal rod and the cross rod can achieve dual purposes. On the one hand, the strength of the lower part of the desk can be strengthened, and on the other hand, the storage tray can be installed. By setting the longitudinal rod and the cross rod at the same height, it is only necessary that the contact part of the storage tray with the longitudinal rod and the cross rod is in the same plane, and the outer bottom surface of the existing storage tray is a plane, so that the existing storage tray can be used in the storage desk of the present application, and the versatility of the installation of the longitudinal rod and the cross rod is relatively strong. When more books are placed in the storage tray, the overall center of gravity of the desk moves down, and the chassis of the desk is more stable. And through the placement opening facing upward, it is convenient to take and put books and other items, which is convenient for students to use. In addition, the storage tray is set on one side of the desk and does not block the space under the desk board, which makes it convenient for students to clean the bottom of the desk and improves cleaning efficiency.

[0009] The storage tray can be in a grid shape and can be made of plastic or metal material.

[0010] In the above-mentioned storage desk, one end of the horizontal rod is connected to the outer side wall of the front end of the longitudinal rod.

[0011] By arranging the cross bar at the front end of the longitudinal bar, it is convenient for students to place their legs during normal classes, and at this time the outer part of the bottom surface of the storage tray will fit into the longitudinal bar, so that the middle and outer parts of the bottom surface of the storage tray can be supported simultaneously by the longitudinal bar and the cross bar, further improving the stability of the bottom plate setting, so that even if a larger storage tray is set up, the storage tray and the longitudinal bar can be fixed, further preparing for increasing the storage space.

[0012] In the above-mentioned storage desk, the lower bottom surface of the bottom of the storage tray has at least one pair of clamping blocks, each pair of clamping blocks is clamped with the longitudinal rod, and the lower ends of the clamping blocks have hooks for hooking the bottom of the longitudinal rod.

[0013] By setting the clamping block and the hook, it is not necessary to improve the longitudinal rod during installation, but only further processing is required on the bottom of the storage tray. In addition, the hook is used to hook and clamp, which improves the convenience of loading and unloading the storage tray.

[0014] In the above-mentioned storage desk, the lower bottom surface of the storage tray has two pairs of positioning strips, which are symmetrically arranged along the front and back of the bottom plate. The cross bar is embedded in one pair of positioning strips, and the side walls of each pair of positioning strips are relatively arranged and fit with the outer side walls of the cross bar.

[0015] Since the storage desk can be open without supporting legs on the left side or on the right side, two pairs of positioning strips are required to adapt to the positioning of the bottom plate and the cross bar in the above two types of storage desks, so as to improve the stability of the storage tray setting without affecting the overall structure.

[0016] In the above-mentioned storage desk, the storage tray includes a base plate arranged on the longitudinal rod and the transverse rod, and an L-shaped extension plate is slidably connected to the base plate along the left and right directions. The storage tray has a clearance opening on the side away from the longitudinal rod, and one end of the extension plate passes through the clearance opening and is connected to the base plate.

[0017] The setting of the extension board allows students to temporarily extend the horizontal space of the bottom plate by pulling out the extension board when in use, thereby facilitating the taking out and placing of books in the storage tray, and improving the convenience of taking out and placing the storage tray. When some books are large in area, the extension board can be pulled out to appropriately extend the horizontal width of the entire storage tray, thereby achieving the purpose of adjusting the storage space of the storage tray according to actual conditions, so that the storage capacity of the storage tray can be adjusted according to one's own needs.

[0018] In the above-mentioned storage desk, a strip-shaped adjustment hole is provided on the bottom of the storage tray, and the length direction of the adjustment hole is arranged along the left-right direction. A nut is fixedly connected to the longitudinal rod, and the bottom of the storage tray is fixedly connected to the nut by a screw passing through the adjustment hole and pressing the bottom of the storage tray against the longitudinal rod.

[0019] The setting of the adjustment hole enables the bottom of the storage tray to move left and right along the longitudinal rod, and the travel of movement can be limited by the length of the adjustment hole. When adjusted to the appropriate position, the positioning with the longitudinal rod can be achieved through the cooperation of the screw and the nut. The above structure can adjust the position of the storage tray by the distance between two adjacent rows of storage desks, realize the adjustable lateral position of the storage tray, and further improve the applicability of the storage tray. Therefore, the appropriate fixed position can be selected according to the size of the teacher's space, and the space of the aisle can be appropriately borrowed.

[0020] In the above-mentioned storage desk, a plurality of fixing holes are provided on the bottom of the storage tray, and the plurality of fixing holes are distributed along the length direction of the longitudinal rod. The bottom of the storage tray is fixedly connected to the longitudinal rod by fasteners passing through the fixing holes.

[0021] The setting of the fixing holes allows the bottom of the storage tray to be directly connected to the longitudinal rod through fasteners. The common and simple structure is adopted, which is convenient for processing the storage tray and also enables convenient loading and unloading of the storage tray.

[0022] In the above-mentioned storage desk, at least two positioning holes are provided on the bottom of the storage tray, and one of the positioning holes is arranged above the cross bar and is fixedly connected to the cross bar by a fastener.

[0023] The positioning holes are set and simple fasteners are used to achieve the positioning between the bottom of the storage tray and the cross bar, further improving the stability of the storage tray installation.

[0024] In the above-mentioned storage desk, at least two groups of the above-mentioned fixing holes are opened on the bottom of the storage tray, and each group of fixing holes is arranged in the longitudinal direction. The lower bottom surface of the bottom of the storage tray has an L-shaped auxiliary positioning plate, and the auxiliary positioning plate has a limit plate arranged at the bottom of the longitudinal rod. The limit plate can slide along the bottom of the longitudinal rod and at least one group of fixing holes is located on the longitudinal rod and is fixed to the longitudinal rod by fasteners.

[0025] The auxiliary positioning plate can be used to form a vertical pre-position between the bottom plate and the longitudinal rod before the fasteners are installed, and then the lateral position adjustment of the storage tray can be achieved through multiple sets of fixing holes opened on the bottom plate. After adjusting to the appropriate position, the limit plate always slides horizontally along the bottom of the longitudinal rod, and at least one set of fixing holes of the bottom plate is located on the longitudinal rod and is fixed to the longitudinal rod by fasteners, thereby achieving the fixation of the storage tray after the lateral adjustment. Therefore, the appropriate fixing position can be selected according to the size of the teacher's space, and the space of the aisle can be appropriately borrowed.

[0026] Then fix it with fasteners to facilitate the installation of the storage tray.

[0027] Compared with the prior art, this storage desk has the following advantages:

[0028] 1. By connecting a storage tray to the longitudinal rod, the storage tray is located between the two supporting legs, occupying more of the space between the supporting legs, and also borrowing part of the space under the table board near the supporting legs, thereby reducing the impact on the desk for lying down and sleeping, while increasing the storage space of the desk.

[0029] 2. The cooperation of the horizontal bar and the vertical bar realizes the L-shaped support of the bottom plate, so that the middle part and the outer edge of one end of the bottom plate can be supported synchronously by the vertical bar and the horizontal bar, further improving the stability of the bottom plate setting.

[0030] 3. The bottom plate can be fixed by means of snap-on connection or fastener connection. When the bottom plate needs to be adjusted laterally, the bottom plate can be adjusted by setting multiple gears, so that the position adjustment and positioning of the storage tray are more stable. Therefore, the appropriate fixed position can be selected according to the size of the teacher's space, and the space in the aisle can be appropriately borrowed. BRIEF DESCRIPTION OF THE DRAWINGS
