Description

Technical Field

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

[0002] With the continuous improvement of living standards, the comfort level for students' lunch breaks has gradually increased. The desks and chairs in existing classrooms are usually replaced with desks and chairs that can be used for lying down and sleeping during lunch breaks. However, there are a large number of students in a classroom and the space in the classroom is limited. Single-leg desks are usually used. Single-leg desks can maximize the space under the desk when lying down and sleeping, and also facilitate students' entry.

[0003] For example, the applicant's prior application [Application Publication No.: CN117179450A] discloses a desk, including a desk top, a cantilever beam, a left table leg and a right table leg. There are two cantilever beams distributed front and back, and both cantilever beams are arranged horizontally. The desk top is laid on the two cantilever beams, and a vertically arranged table leg is connected between the left ends of the two cantilever beams and the left table leg. When the above desk is in use, students usually press on the back of the desk top, and the pressure on the suspended side of the desk top is transmitted to the table leg through the cantilever beam, so that the force at the connection between the cantilever beam and the table leg is relatively large, which is easy to cause deformation at this place.

[0004] The existing method usually adopts adding a reinforcement plate at the connection between the cantilever beam and the table leg. Regarding the structure of the reinforcement plate here, the Chinese patent application [Authorization Announcement No.: CN21501543U] discloses a new type of stool, including an inner frame bracket, an outer frame bracket, a rotating shaft and a fixed panel, the inner frame bracket and the outer frame bracket are rotatably connected by the rotating shaft, the inner frame bracket and the outer frame bracket are connected and fixed by the fixed panel, the rotating shaft is composed of a female buckle extending into the inner cavity of the outer frame bracket and a male buckle matching the female buckle, and the male buckle and the female buckle are matched and installed to limit the rotating shaft and the outer frame bracket, the bottom of the inner frame bracket and the outer frame bracket are both provided with a U-shaped base, the top of the inner frame bracket and the outer frame bracket are both provided with a U-shaped top plate, and the connection between the inner frame bracket and the U-shaped base and the U-shaped top plate, and the connection between the outer frame bracket and the U-shaped top plate are both provided with riveted reinforcement members.

[0005] A plurality of riveted reinforcements are arranged at the connection between the inner frame bracket and the outer frame bracket of the above-mentioned stool, and it can be clearly seen from the drawings in the specification of the above-mentioned application that the riveted reinforcements are a plurality of plate-shaped structures, which are used to increase the strength of the connection and the load-bearing capacity of the stool. The structure is applied to the connection between the cantilever beam and the table leg. Since the suspended side of the cantilever beam is subjected to greater force, a plate-shaped reinforcement structure is adopted. When the plate-shaped structure is pressed downward at the lower end of the cantilever beam, the cantilever beam exerts downward pressure on the reinforcement block. The lower end of the reinforcement block is likely to squeeze the table leg and cause the table leg to deform. The upper end of the reinforcement plate is likely to cause the cantilever beam to deform under the influence of the interaction force, which affects the normal use of the single-leg desk and reduces the stability of use. Utility Model Content

[0006] The object of the present utility model is to address the above problems existing in the prior art and propose a high-strength desk. The technical problem to be solved by the present utility model is: how to solve the problem of low stability of the reinforcing piece between the cantilever beam and the table leg of the existing single-leg desk.

[0007] The object of the present utility model can be achieved by the following technical solutions:

[0008] A high-strength desk, comprising a tabletop, a cantilever beam, and table legs arranged vertically. The tabletop is laid on the cantilever beam. One end of the cantilever beam is connected to the table legs. The upper end of the table legs is fixedly connected to the tabletop. The side walls on the front and rear sides of the table legs are both support walls, and the support walls are both located between two chamfered walls. It is characterized in that a reinforcing piece formed by bending is provided at the connection between the cantilever beam and the table legs. The reinforcing piece is U-shaped. Both the front and rear sides of the reinforcing piece have triangular reinforcing parts. The upper wall of the reinforcing part is connected to the outer side wall of the cantilever beam, and the side wall of the reinforcing part is connected to the side wall of the support wall.

[0009] Working principle: A reinforcing piece is provided at the connection between the cantilever beam and the table legs. The reinforcing piece is bent and U-shaped, and both the front and rear sides of the reinforcing piece have triangular reinforcing parts. The use of the U-shaped plate enables the reinforcing piece to withstand greater pressure and increases the connection area between the reinforcing piece and the cantilever beam and the table legs. The reinforcing part is triangular in shape and has high stability. By connecting the upper wall of the reinforcing part to the outer side wall of the cantilever beam and the side wall of the reinforcing part to the side wall of the support wall, the force application points of the reinforcing part transmitted to the table legs are on both sides. When the suspended side of the cantilever beam is pressed down by pressure, the pressure is transmitted to the table legs. The connection between the cantilever beam and the table legs is subjected to an inclined downward pressure. After the reinforcing part is subjected to pressure, the pressure is transmitted from the side to the support wall. The support wall is stressed on one side in the thickness direction, and it is not easy to deform in the thickness direction and can provide greater support force. To deform, the entire table leg needs to undergo lateral deformation, not just simply adding a force application point. The connection position is also utilized to prevent the table leg from deforming during use, improving the load-bearing capacity of the reinforcing part. Through the setting of the shape of the reinforcing piece and the connection relationship, the compressive resistance performance can be enhanced through its own shape. By connecting to the outer side wall of the cantilever beam and the support wall, the strength of the support wall of the table leg is relatively high, and it is not easy to cause the table leg to deform, improving the force-bearing effect of the reinforcing piece, thereby achieving the purpose of increasing the load-bearing capacity and use stability of the high-strength desk.

[0010] In the above high-strength desk, the support wall is in a flat plate shape.

[0011] The support wall in a flat plate shape can provide better support for the reinforcing part, enabling the force transmitted to the support wall by the reinforcing part to be stably supported, thereby improving the stability of the desk.

[0012] In the above-mentioned high-strength desk, the reinforcing part is in the shape of a flat plate, and the outer wall of the reinforcing part is flush with the outer wall of the corresponding supporting wall.

[0013] By making the outer wall of the reinforcing part flush with the outer wall of the corresponding supporting wall, when the reinforcing part is subjected to pressure, the pressure is completely transmitted to the supporting wall from the side. One side of the thickness of the supporting wall is stressed, and this stress direction enables the supporting wall to provide a relatively high supporting force to the reinforcing part; the reinforcing part does not protrude from the side relative to the supporting wall, so that the reinforcing part does not bulge outward relative to the supporting wall from the side, which does not affect the appearance and use of the table legs, and the aesthetics of the desk is better.

[0014] In the above-mentioned high-strength desk, the table legs have chamfered walls that are distributed left and right and are arc-shaped. The supporting walls are all located between the two chamfered walls. The reinforcing piece further includes a connecting part that is inclined downward from top to bottom. The connecting part is arc-shaped. The upper end of the connecting part is connected to the cantilever beam, the lower end of the connecting part is connected to the corresponding chamfered wall, and the connecting part is located between the two reinforcing parts.

[0015] The setting of the connecting part avoids scratching of the connecting part when the student's hand is placed under the tabletop, improves the safety performance of the desk, and through the arc-shaped setting, improves the supporting effect of the reinforcing piece, thereby improving the stability of the desk during use.

[0016] In the above-mentioned high-strength desk, both the upper and lower ends of the connecting part have arc-shaped connecting walls. The connecting wall at the upper end is fixedly attached to the lower wall of the cantilever beam, and the connecting wall at the lower end is fixedly attached to the chamfered wall.

[0017] The setting of the connecting wall improves the connection strength with the cantilever beam and the corresponding chamfered wall, places the cantilever beam and the corresponding chamfered wall inside the reinforcing piece, and enhances the connection strength between the reinforcing piece and the cantilever beam and the chamfered wall.

[0018] In the above-mentioned high-strength desk, there are two table legs that are distributed front and back along the tabletop. This high-strength desk further includes table feet one and table feet two arranged on the left and right sides of the tabletop. Both table legs are connected to table feet one. A connecting crossbar is connected to the table legs, and the connecting crossbar is connected to the front end of table feet two. The front ends of table feet one and table feet two are flush, and the rear end of table feet two is shorter than the rear end of table feet one.

[0019] In order to make room for the space at the bottom of the table, the connecting cross bar is set close to the front end to facilitate students' entry and exit. However, after being set forward, the distance between the rear end of the second table foot and the connecting cross bar is large, and the force arm is long. When the table top is subjected to downward pressure, the connection between the connecting cross bar and the second table foot is prone to downward deformation, causing the front end of the second table foot to tilt upward and deform significantly. By making the rear end of the second table foot shorter than the rear end of the first table foot, the length of the force arm between the rear end of the second table foot and the connecting cross bar is reduced, the overall length of the second table foot is shortened, and the downward deformation of the connecting cross bar is reduced, so that the front end of the second table foot is not easy to tilt up, and the stability of the desk is achieved as much as possible. In addition, the length of the rear end of the second table foot is shortened, making it more convenient for students to enter and exit.

[0020] In the above-mentioned high-strength desk, the length ratio of the first table leg to the second table leg is 8 / 10 to 9 / 10.

[0021] The setting of this length ratio ensures that the length of the second table leg can not only meet the purpose of supporting stability, but also enhance the supporting strength of the connecting cross bar when the suspended side of the table top is subjected to force, thereby improving the stability of the setting.

[0022] In the above-mentioned high-strength desk, a reinforcing longitudinal rod is provided between the two table legs, one end of the connecting cross rod is connected to the front end of the reinforcing longitudinal rod, and the other end of the connecting cross rod is bent downward and vertically connected to the second table foot.

[0023] The setting of the reinforced longitudinal rod improves the connection strength of the two table legs, and also makes the connecting cross bar connected horizontally and vertically to the reinforced longitudinal rod. The connecting cross bar is set parallel to the cantilever beam above. One end of the connecting cross bar is bent downward and vertically connected to the second bottom foot of the table. The force of the table legs can be vertically applied to the second bottom foot of the table, making the effect more stable. The second bottom foot of the table can provide a relatively stable supporting force to the connecting cross bar.

[0024] In the above-mentioned high-strength desk, the reinforcing portion is triangular in shape, and the outer edge of the reinforcing portion is welded to the outer side wall of the table leg and the outer side wall of the cantilever beam.

[0025] The triangular shape enables the reinforcement part to provide better support while avoiding occupying a large space and causing interference to students' entry and exit. The welding method can both ensure the sealing effect of the reinforcement cavity and simplify the installation.

[0026] Compared with the prior art, this high-strength desk has the following advantages:

[0027] 1. By setting the shape of the reinforcing piece and its connection relationship, the compressive resistance can be enhanced through its own shape. By connecting to the outer wall and the supporting wall of the cantilever beam, the strength of the supporting wall of the table leg is relatively high, which can provide a large supporting force. To deform, the entire table leg needs to undergo lateral deformation, not just simply adding a stress point. Also, by using the connection position, it can prevent the table leg from deforming during use, making it difficult for the table leg to deform and improving the stress effect of the reinforcing piece, thereby achieving the purpose of increasing the load-bearing capacity and use stability of the high-strength desk.

[0028] 2. By making the rear end of the first table bottom foot shorter than the rear end of the second table bottom foot, the lever arm length between the rear end of the first table bottom foot and the connecting cross bar is reduced, and the overall length of the first table bottom foot becomes shorter, so that the connecting cross bar reduces the downward deformation amount. As a result, the front end of the first table bottom foot is not easy to tilt, achieving the stable effect of the desk as much as possible. And by shortening the length of the rear end of the first table bottom foot, it is more convenient for students to enter and exit. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following are specific embodiments of the present utility model, in conjunction with the accompanying drawings, to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0039] As Figure 1 and Figure 2 shown, this high-strength desk includes a tabletop 1, cantilever beams 2, and table legs 3 arranged vertically. There are two cantilever beams 2 distributed in the front-rear direction of the tabletop 1. The tabletop 1 is laid on the cantilever beams 2. One end of the cantilever beam 2 is perpendicularly connected to the table leg 3. The upper end of the table leg 3 is fixedly connected to the tabletop 1. The table leg 3 has two chamfered walls 31 distributed left and right and in an arc shape, and two support walls 32 distributed front and rear and in a planar shape. The support walls 32 are both located between the two chamfered walls 31.

[0040] Specifically, as Figures 1-8 shown, at the connection between the cantilever beam 2 and the table leg 3, there is a reinforcing piece 4 formed by bending. The reinforcing piece 4 is U-shaped. Both the front and rear sides of the reinforcing piece 4 have triangular reinforcing parts 41. The upper wall of the reinforcing part 41 is connected to the outer side wall of the cantilever beam 2, and the side wall of the reinforcing part 41 is connected to the side wall of the support wall 32.

[0041] Working principle: At the connection between the cantilever beam 2 and the table leg 3, there is a reinforcing piece 4. The reinforcing piece 4 is bent and U-shaped, and both the front and rear sides of the reinforcing piece 4 have triangular reinforcing parts 41. The use of a U-shaped plate enables the reinforcing piece 4 to withstand greater pressure and increases the connection area between the reinforcing piece 4 and the cantilever beam 2 and the table leg 3. The reinforcing part 41 is triangular in shape and has high stability. By connecting the upper wall of the reinforcing part 41 to the outer side wall of the cantilever beam 2 and the side wall of the reinforcing part 41 to the side wall of the support wall 32, the force application points of the reinforcing part 41 transmitted to the table leg 3 are on both sides. When the suspended side of the cantilever beam 2 is pressed down by pressure, the pressure is transmitted to the table leg 3. When the connection between the cantilever beam 2 and the table leg 3 is subjected to an inclined downward pressure, after the reinforcing part 41 is subjected to the pressure, the pressure is transmitted from the side to the support wall 32. One side of the thickness of the support wall 32 is stressed, and the support wall 32 is not easily deformed when stressed in the thickness direction and can provide a large supporting force. To deform, the entire table leg 3 needs to undergo lateral deformation, not just simply adding a force application point. The connection position is also utilized to prevent the table leg 3 from deforming during use, improving the load-bearing capacity of the reinforcing part 41. Through the shape setting and connection relationship of the reinforcing piece 4, the compressive resistance performance can be enhanced through its own shape. By connecting with the outer side wall of the cantilever beam 2 and the support wall 32, the strength of the support wall 32 of the table leg 3 is high, and the table leg 3 is not easily deformed, improving the force application effect of the reinforcing piece 4, thereby achieving the purpose of increasing the load-bearing capacity and use stability of the high-strength desk.

[0042] A closed reinforcing cavity is formed by enclosing between the outer sidewalls of the above-mentioned reinforcing piece 4 and the cantilever beam 2 and the outer sidewall of the table leg 3. The closed reinforcing cavity has higher stability than a single plate-like structure and is less likely to deform.

[0043] As Figures 3-8 shown, the reinforcing portion 41 is in the shape of a flat plate, and the outer wall of the reinforcing portion 41 is flush with the outer wall of the corresponding supporting wall 32. The reinforcing piece 4 further includes a connecting portion 42 that is inclined downward from top to bottom. The connecting portion 42 is arc-shaped. The upper end of the connecting portion 42 is connected to the cantilever beam 2, and the lower end of the connecting portion 42 is connected to the chamfered wall 31. The connecting portion 42 is located between the two reinforcing portions 41. Both the upper and lower ends of the connecting portion 42 have arc-shaped connecting walls 42a. The connecting wall 42a at the upper end is fixedly attached to the lower wall of the cantilever beam 2 in a fitting manner, and the connecting wall 42a at the lower end is fixedly attached to the corresponding chamfered wall 31 in a fitting manner.

[0044] As Figures 1-4 shown, there are two table legs 3, which are distributed front and back along the tabletop 1. This high-strength desk further includes table feet one 6 and table feet two 7 provided on the left and right sides of the tabletop 1. Both table legs 3 are connected to the table feet one 6. A connecting cross bar 8 is connected to the table leg 3. The connecting cross bar 8 is connected to the front end of the table feet two 7. The front end of the table feet one 6 is flush with the front end of the table feet two 7. The rear end of the table feet two 7 is shorter than the rear end of the table feet one 6. The length ratio of the table feet one 6 to the table feet two 7 is 8 / 10 to 9 / 10. There is a reinforcing longitudinal bar 33 between the two table legs 3. One end of the connecting cross bar 8 is vertically connected to the front end of the reinforcing longitudinal bar 33, and the other end of the connecting cross bar 8 is bent downward and vertically connected to the table feet two 7.

[0045] As Figure 1 、 Figure 2 and Figure 5 shown, the outer edge of the reinforcing portion 41 is welded to the outer sidewall of the table leg 3 and the outer sidewall of the cantilever beam 2.

[0046] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model belongs can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
