Several anti-slip strips 42 are provided and are arranged at equal intervals. An elastic plate 43 is installed on the bottom of the support leg 3.

[0026] As a technical optimization of this utility model, by setting the elastic buffer component 4, the anti-slip strip 42 at the bottom of the rubber block 41 can not only increase the friction between the support leg 3 and the ground, preventing the support leg 3 from sliding randomly during use and ensuring the safety of students, but also the anti-slip strip 42 is made of elastic material, which can avoid collision noise during use. Moreover, the elastic material of the rubber block 41 and the elastic plate 43 can effectively buffer the impact force between the support leg 3 and the ground when moving, greatly reducing the noise generated when dragging the support leg 3, making the movement of the desk and chair more stable and quiet.

[0027] refer to Figure 2 The buffer protection component 5 includes anti-collision blocks 51, and several anti-collision blocks 51 are provided and are arranged at equal distances. Elastic blocks 52 are installed on the outer side of the anti-collision blocks 51. A rubber plate 54 is installed on the back of the desk and chair body 1, and a buffer groove 53 is opened on the back of the rubber plate 54.

[0028] As a technical optimization of this utility model, by setting up a buffer protection component 5, the anti-collision block 51 and the elastic block 52 on its outer side can play a good buffering role when the desk and chair body 1 accidentally collides with other objects or is collided with, reducing the noise generated by the collision. The rubber plate 54 and buffer groove 53 on the back of the desk and chair body 1 further enhance the overall buffering performance, preventing damage to the desk and chair body 1 from the collision, while effectively absorbing the energy generated by the collision and reducing the transmission of noise.

[0029] refer to Figure 3The top of the rubber block 41 is provided with a connecting groove 6, and a support block 7 is installed inside the connecting groove 6. The top of the support block 7 is installed with the bottom of the support leg 3.

[0030] As a technical optimization of this utility model, by setting the connecting groove 6 and the support block 7, the support block 7 can effectively support the interior of the rubber block 41 through the connecting groove 6, so that the bottom of the support leg 3 is separated from the ground, thereby reducing the noise generated by the friction between the support leg 3 and the ground during use.

[0031] refer to Figure 3 An elastic strip 8 is installed on the outer side of the support leg 3. Several elastic strips 8 are provided and are arranged at equal intervals. Connecting blocks 9 are installed between the elastic strips 8.

[0032] As a technical optimization of this utility model, by setting elastic strip 8 and connecting block 9, elastic strip 8 can play a buffering role on the outside of support leg 3. When the desk and chair collide slightly with other objects, elastic strip 8 can reduce collision noise. Connecting block 9 enhances the connection strength between elastic strips 8, making the entire protective structure more stable and further improving the protection and noise reduction capabilities of support leg 3.

[0033] refer to Figure 2 The outer side of the elastic block 52 is arc-shaped, and a sponge block 10 is installed between the elastic blocks 52. An anti-slip plate 11 is installed on the front of the backing plate 2.

[0034] As a technical optimization of this utility model, by setting up an elastic block 52, a sponge block 10 and an anti-slip plate 11, the arc-shaped design of the outer side of the elastic block 52, together with the sponge block 10, can better disperse the impact force when the desk and chair are hit, and reduce the collision noise. The anti-slip plate 11 on the front of the backrest 2 can prevent the student's body from sliding down when leaning on the backrest 2, improve the stability of the student's sitting posture, and also indirectly reduce the possibility of noise from the desk and chair caused by body shaking.

[0035] refer to Figure 2 A buffer block 12 is installed on the front of the desk and chair body 1. Several buffer blocks 12 are provided, and the several buffer blocks 12 are arranged at equal distances.

[0036] As a technical optimization of this utility model, by setting a buffer block 12, the buffer block 12 on the front of the desk and chair body 1 can play a buffering role when the desk and chair body 1 collides with the object in front or when the student accidentally collides with the front of the desk and chair body 1, reducing the noise generated by the collision, protecting the desk and chair body 1 and the user, and creating a quieter and safer learning environment for students.

[0039] The working principle and usage process of this utility model are as follows: When the desk and chair need to be moved, the rubber block 41 at the bottom of the support leg 3 and the anti-slip strip 42 at its bottom first contact the ground. The anti-slip strip 42 is made of elastic material, which not only increases the friction with the ground and prevents the support leg 3 from sliding, but also avoids collision noise caused by friction. At the same time, the rubber block 41 and the elastic plate 43 will buffer the impact force of the support leg 3 on the ground when it moves, greatly reducing the noise generated when dragging the support leg 3, ensuring a smooth and quiet movement. When the desk and chair body 1 accidentally collides with other objects during use, the anti-collision block... The elastic block 51 and its outer side 52 will initially absorb the impact force, providing good cushioning through their own elastic deformation and reducing noise generated by the collision. The rubber plate 54 and buffer groove 53 on the back of the desk and chair body 1 can further absorb the energy generated by the collision, enhancing the overall cushioning performance and preventing damage to the desk and chair body 1 due to the collision. At the same time, it reduces noise transmission. The support block 7 supports the interior of the rubber block 41 through the support groove, allowing the rubber block 41 to be supported by the anti-slip strip 42 and the ground. This creates a certain gap between the bottom of the support leg 3 and the ground, reducing the noise generated by the direct friction between the support leg 3 and the ground. In daily use, when students lean against the backrest 2, the anti-slip plate 11 on the front of the backrest 2 can prevent the body from sliding down, improve the stability of the sitting posture, and indirectly reduce the noise caused by body swaying. The combination of the elastic block 52 and the sponge block 10 can better disperse the impact force when the desk and chair body 1 is hit, reducing the collision noise. The buffer block 12 on the front of the desk and chair body 1 can buffer the impact force when the desk and chair collides with the object in front or when the student accidentally bumps into the front of the desk and chair body 1, protecting the desk and chair body 1 and the user, and reducing the collision noise. The buffer plate 13 on the top of the desk and chair body 1 and its opening The buffer groove 53 is designed to absorb vibration energy when the top is impacted or when objects are placed on it, reducing noise generation, protecting the top structure of the desk and chair, and extending its service life. During the entire use process, the elastic strip 8 and connecting block 9 on the outside of the support leg 3 also play a role. When the desk and chair collide slightly with other objects, the elastic strip 8 can buffer the impact and reduce collision noise, while the connecting block 9 enhances the connection strength between the elastic strips 8, making the protective structure more stable and further improving the protection and noise reduction capabilities of the support leg 3, achieving the effect of moving and reducing noise, and enhancing the use effect of the desk and chair.

[0040] In summary, this desk and chair design that reduces noise during movement reduces noise generated during collisions by using an elastic buffer component 4 in conjunction with a buffer protection component 5 to provide elastic cushioning to the outer sides of the desk and chair body 1, backrest 2, and support legs 3. This solves the problem that existing desks and chairs generate noise during movement, which can disrupt classroom order, affect teachers' teaching and students' listening, and cause students to experience irritability, anxiety, and other negative emotions when in a noisy environment for a long time, reducing their enthusiasm and initiative for learning, causing inconvenience in use, and reducing the effectiveness of the desks and chairs.
