Description

Technical Field

[0001] The utility model relates to the field of desks and chairs, and particularly relates to a set of desks and chairs that is convenient to move. Background Art

[0002] Desks and chairs are the desks and chairs used by students in class. They are a type of desks and chairs, also called student desks and chairs. Schools in our country have always continued to use traditional miscellaneous wood to manufacture desks and chairs. Desks and chairs are necessities in students' school days. Desks and chairs of various materials and types have their own advantages. For example, desks and chairs with table tops and those with plastic seats are relatively strong and durable, and desks and chairs with middle drawer boards have the advantages of large capacity and good corrosion resistance.

[0003] However, the existing desks and chairs are not convenient to move. The desks and chairs in the classroom are often placed in a mess, and when moving, the table and the chair need to be moved separately, which is time-consuming and laborious.

[0004] Therefore, it is very necessary to propose a set of desks and chairs that is convenient to move to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a set of desks and chairs that is convenient to move, so as to solve the problems that the existing desks and chairs are not convenient to move, the desks and chairs in the classroom are often placed in a mess, and when moving, the table and the chair need to be moved separately, which is time-consuming and laborious.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A set of desks and chairs that is convenient to move, including a table body and a chair body. The table body includes two support legs. Telescopic lifting rods are arranged at the tops of the two support legs. A tabletop is fixed at the tops of the two lifting rods. First bottom plates are fixed at the bottoms of the two support legs. Protruding blocks are fixed on both sides of the tops of the two first bottom plates. Inner embedding grooves are opened on both sides of the bottoms of the two first bottom plates. Inner cavities are opened in the two protruding blocks. The two inner cavities communicate with the corresponding inner embedding grooves. Springs are fixed at the tops of the two inner cavities. A fixing seat is fixed at the bottom of the spring. A moving wheel is rotatably connected to the bottom of the fixing seat. The bottom of the moving wheel extends out of the bottom of the corresponding first bottom plate. Two second bottom plates are rotatably connected to the bottom of the chair body.

[0007] Preferably, through holes are opened on one side of the two first bottom plates. Plug posts are inserted into the through holes. A connection hole for the plug post to pass through is opened on one side of the fixing seat.

[0008] Preferably, sliding tracks are fixed on both sides of the bottom of the tabletop. A drawer is slidably installed between the two sliding tracks.

[0009] Preferably, sliding grooves are formed at the tops of both support legs, two lifting rods are slidably arranged inside the corresponding sliding grooves, fixing screws are arranged on one side of the two support legs facing each other, and one ends of the two fixing screws are pressed against the surfaces of the corresponding lifting rods.

[0010] Preferably, a magnet is arranged on the outer side of the protruding block, and the two second bottom plates are magnetically connected to the outer sides of the corresponding protruding blocks.

[0011] Preferably, anti-slip pads are wrapped around the bottoms of the two first bottom plates and the two second bottom plates.

[0012] The technical effects and advantages of the present utility model:

[0013] 1. In the actual operation of the present utility model, when it is necessary to move the table body, the first bottom plate can be lifted, so that the fixing seat and the moving wheels inside the first bottom plate automatically pop out by the elastic force of the spring. After the popping is completed, the position of the fixing seat can be fixed by the insertion post, so that the overall table body can be moved. At the same time, the two second bottom plates at the bottom end of the chair body can be rotated to 90 degrees, so that the second bottom plates can be attached to the top of the first bottom plate. When the table body moves, the chair body can be driven to move synchronously, reducing the time for personnel to move.

[0014] 2. When the desks and chairs are moved, the insertion post can be pulled out. At this time, the self-pressure of the table body will squeeze the moving wheels, so that the moving wheels and the fixing seat can retract into the inner cavity. By inserting the insertion post again, the bottom end of the moving wheels can be supported to prevent the moving wheels from popping out and causing the table body to move.

[0015] 3. When the second bottom plate is placed on the top of the first bottom plate, one side of the second bottom plate can be magnetically attracted to the protruding block to play a fixing role. At the same time, the protruding block can intercept the second bottom plate to prevent the chair body from moving and falling during the moving process. Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a kind of desks and chairs convenient for moving as shown in Figure 1 - Figure 4 The desks and chairs include a table body and a chair body 8. The table body includes two support legs 2. Telescopic lifting rods 3 are arranged at the tops of the two support legs 2. A table board 4 is fixed at the tops of the two lifting rods 3. First bottom plates 1 are fixed at the bottoms of the two support legs 2. Chutes are opened at the tops of the two support legs 2. The two lifting rods 3 are slidably arranged inside the corresponding chutes. Fixing screws are arranged on one side of the two support legs 2 facing each other. One ends of the two fixing screws are pressed against the surfaces of the corresponding lifting rods 3.

[0023] The height of the table body can be adjusted by sliding the two lifting rods 3 in the chutes to adjust the positions of the lifting rods 3 in the chutes, so as to meet the needs of different students. And the height of the lifting rods 3 can be fixed by using the fixing screws.

[0024] Protruding blocks 10 are fixed on both sides of the tops of the two first bottom plates 1. Inner embedding grooves are opened on both sides of the bottoms of the two first bottom plates 1. Inner cavities 12 are opened in the two protruding blocks 10. The two inner cavities 12 communicate with the corresponding inner embedding grooves. Springs 13 are fixed at the tops of the two inner cavities 12. The bottoms of the springs 13 are fixed with fixed seats 14. The bottoms of the fixed seats 14 are rotatably connected with movable wheels 11. The bottoms of the movable wheels 11 extend out of the bottoms of the corresponding first bottom plates 1. The bottoms of the chair body 8 are rotatably connected with two second bottom plates 9.

[0025] Through holes are opened on one side of the two first bottom plates 1. Insertion posts 5 are inserted into the through holes. Connecting holes for the insertion posts 5 to pass through are opened on one side of the fixed seats 14.

[0026] In the actual operation of the present utility model, when it is necessary to move the table body, the first bottom plate 1 can be lifted, so that the fixing seat 14 and the moving wheels 11 inside the first bottom plate 1 are automatically ejected by the elastic force of the spring 13. After the ejection is completed, the position of the fixing seat 14 can be fixed by the insertion post 5, so that the overall table body can be moved. At the same time, the two second bottom plates 9 at the bottom end of the chair body 8 can be rotated to 90 degrees, so that the second bottom plate 9 can be attached to the top end of the first bottom plate 1.
