At the moment, the idler wheels play a main supporting role, the student rotates the whole desk and chair towards the position far away from the seat plate to incline the desk and chair, the cross rod can be held to be matched with the idler wheels to push the desk and chair, carrying is not needed, and more labor is saved.

Description

Technical Field

[0001] The utility model relates to the technical field of desks and chairs, in particular to a freely adjustable multifunctional desk and chair. Background Art

[0002] Desks and chairs are desks and chairs used by students in class. They are a type of desks and chairs, also called student desks and chairs, school desks and chairs. Desks and chairs can be divided according to age, material, and function. The ingredients of desks and chairs are based on quality and size requirements. The process of sawing finished materials and various artificial boards into raw materials of various specifications is called batching.

[0003] Today's desks and chairs have a simple structure and single function. Especially when there are outdoor activities, such as cultural performances, students may have to carry their chairs out and gather on the playground. Some students have less strength and will be tired after moving chairs for a long time. Therefore, we provide a freely adjustable multifunctional desk and chair. Utility Model Content

[0004] The purpose of the utility model is to provide a freely adjustable multifunctional desk and chair to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A freely adjustable multifunctional desk and chair comprises a seat plate, the bottom of which is fixedly connected to a seat leg, there are four seat legs in total, and the four seat legs are symmetrically distributed, a first groove is provided at the bottom of the seat leg, and oblique grooves are provided on the corresponding two side edges of the seat leg, a vertical groove is provided inside the seat leg and on one side of the oblique groove, the vertical groove is connected to the oblique groove, and the oblique groove and the vertical groove are both connected to the first groove, a slide rod is slidably connected inside the vertical groove, and a roller is fixedly connected between the two slide rods.

[0007] The slide bar can slide back and forth in the oblique groove and the vertical groove to change the position of the roller in the first groove. When the slide bar is in the upper position of the oblique groove, the seat legs are in contact with the ground, and the rollers are also in contact with the ground, but the seat legs still play a major supporting role. When the desks and chairs need to be moved as a whole, students can lift the desks and chairs slightly upwards through the cross bar. At this time, due to the weight of the rollers themselves, the rollers will drive the slide bar to slide from the oblique groove into the vertical groove. Then the students put down the desks and chairs, and the slide bar will enter the upper position of the vertical groove. At this time, the rollers play a major supporting role. The students can then turn the desks and chairs as a whole away from the seat plate to tilt them, and then they can hold the cross bar and cooperate with the rollers to push the desks and chairs. There is no need to carry them, which is more labor-saving.

[0008] Preferably, the top of the seat seat is fixedly connected to a support rod, there are two support rods in total, the two support rods are symmetrically distributed, the top of the support rod is fixedly connected to a cross rod, the outside of the cross rod is rotatably connected to a seat back, the inside of the seat back is threadedly connected to a positioning bolt, and a first positioning hole is opened on the inside of the cross rod away from the seat back, and the first positioning hole is used in conjunction with the positioning bolt.

[0009] The seat back can be rotated on the cross bar to adjust the position of the seat back. When the seat back is adjusted to be parallel to the ground, it can be used as a table, and the adjusted seat back is positioned by the positioning bolts and the first positioning holes.

[0010] Preferably, a second positioning hole is formed inside the cross bar on a side close to the seat back, and the second positioning hole is used in conjunction with a positioning bolt.

[0011] The second positioning hole is used to receive the positioning bolt to prevent the positioning bolt from abutting against the cross bar, causing the positioning bolt to protrude and get hooked.

[0012] Preferably, a second groove is formed on the top of the seat back, and the second groove is used in conjunction with a positioning bolt.

[0013] The second groove is used to receive the bolt head of the positioning bolt, and cooperates with the second positioning hole to prevent the positioning bolt from protruding out of the seat back.

[0014] Preferably, a third groove is formed on a side of the seat back close to the support rod, and the third groove cooperates with the support rod.

[0015] The third groove is used to store the support rod to prevent the seat back from colliding with the support rod after being lowered.

[0016] Preferably, a fourth groove is formed on the top of the seat back.

[0017] The fourth groove is designed to allow students to hold the crossbar without hindrance.

[0018] Preferably, the outer side wall of the slide bar is in contact with the inner side wall of the vertical groove.

[0019] The slide bar is limited to ensure the stability of the slide bar moving in the vertical groove.

[0020] Preferably, the outer side wall of the slide bar is in contact with the inner side wall of the inclined groove.

[0021] Make sure the slide bar slides smoothly in both the vertical and diagonal slots.

[0022] The beneficial effects achieved by the utility model are as follows: through the arrangement of the seat plate, the seat legs, the first groove, the inclined groove, the vertical groove, the sliding rod, the roller, the support rod, the cross bar, the seat back, the positioning bolts, the first positioning hole, the second positioning hole, the second groove, the third groove and the fourth groove, the sliding rod can slide back and forth in the inclined groove and the vertical groove, and the position of the roller in the first groove can be changed. When the sliding rod is in the upper position of the inclined groove, the seat legs are released from the ground, and the rollers are also released from the ground. However, the seat legs still play a major supporting role. When the desks and chairs need to be moved as a whole, the students can lift them slightly upwards through the cross bar. The desks and chairs, at this time, due to the weight of the rollers themselves, the rollers will drive the slide bar to slide from the oblique groove into the vertical groove. Then the students put down the desks and chairs, and the slide bar will enter the upper position of the vertical groove. At this time, the rollers play a major supporting role. The students then turn the desks and chairs as a whole away from the seat plate to tilt them, and then they can hold the cross bar and cooperate with the rollers to push the desks and chairs. There is no need to carry them, which is more labor-saving. The seat back can be rotated on the cross bar to adjust the position of the seat back. When the seat back is adjusted to be parallel to the ground, it can be used as a table, and the adjusted seat back is positioned by the positioning bolts and the first positioning hole.
