Description

Desk with antiskid function

Technical Field

The invention relates to the technical field of teaching equipment, in particular to a desk with an anti-skidding function.

Background

In the teaching places of primary schools, middle schools and the like, the desk is a necessary teaching facility in classrooms. When a teacher goes to school, students can place books, stationery and the like on a desk. In order to ensure the tidiness in the classroom, the desks and the chairs need to be arranged tidily. And the pupils are often playful in the afterclass time due to the characteristics of liveliness and good movement and the like, and inevitably touch the desk in the process, so that the desk is inclined. For this reason, it is often necessary for students to rearrange the desks after school, which takes a long time. The school students can consume large physical strength due to the fact that the school students are younger and have little strength. Therefore, the valuable learning time of the students is wasted, and the students are subjected to large physical burden. Therefore, the existing desk has the defect of easy sliding, and causes great burden to students.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provides a desk with an anti-skidding function.

The invention solves the technical problems through the following technical scheme:

a desk with an anti-skid function comprises a desktop, wherein at least three desk legs are arranged below the desktop, vertical plates are fixedly connected to the desk legs, and cross beams are fixedly arranged on the vertical plates; a stud is arranged on the cross beam in a penetrating way and is in threaded connection with the cross beam; a sucker is arranged at the bottom of the stud, a shell is arranged above the sucker, an annular pressing plate is arranged above the shell, and a first spring is arranged between the shell and the pressing plate; the stud penetrates through the shell, the first spring and the pressing plate simultaneously; a wrench capable of extruding the pressing plate downwards is arranged above the pressing plate and connected to the stud through a pin shaft; the wrench is positioned below the cross beam; the lower edge of the shell is abutted against the upper surface of the sucker; and a pressing mechanism capable of applying downward force to the stud is further arranged on the stud.

The sucking disc can be sucked on the floor of a classroom, so that the desk has an anti-skidding function and cannot damage the floor. The stud is adjusted to move downwards, so that the stud can extrude the sucker, and the sucker is further sucked on the floor; the adjusting stud moves upwards to enable the bolt to drive the sucker to move upwards, so that the sucker is separated from the floor. The first spring can extrude the shell by applying force on the wrench, and the shell is extruded on the sucker, so that the sealing performance of the sucker is improved, air leakage is avoided, and the anti-skid performance of the desk is further improved.

The table legs are provided with a plurality of vertically distributed mounting holes which are distributed at equal intervals along the table legs; the vertical plate is fixedly connected to the table legs through screws which are in threaded connection with the mounting holes.

The top of the stud is provided with a knob; the knob is located above the cross beam. The distance between the stud and the ground can be adjusted through the knob. When the sucker needs to be separated from the ground, the stud can be moved upwards through the knob; when the sucker is required to be sucked on the floor, the stud can be moved downwards through the knob. The knob is arranged, so that the adjustment is easier, more convenient and faster.

The lower edges of the sucking disc and the shell are both circular, and the radius of the lower edge of the sucking disc is larger than that of the lower edge of the shell. The lower edge of the shell is abutted to the upper surface of the sucker, so that the contact between the lower surface of the sucker and the ground is guaranteed, the sealing performance of the sucker is improved, and the anti-skidding capacity of the desk is further improved.

The shell comprises a conical shell body and an annular part arranged at the lower end part of the shell body; the annular parts are transversely distributed; the lower surface of the annular part is provided with clamping grooves which are distributed annularly; the upper surface of the sucker is provided with first bulges which are distributed annularly; the first bulge is clamped in the clamping groove. The clamping groove is clamped with the first protrusion, the annular part can prevent the sucker from deforming at the position abutted to the annular part, and the edge of the sucker is guaranteed to be in contact with a floor completely, so that the sealing performance of the sucker during use is improved, the suction force is improved, and the anti-skidding capacity of the desk is further improved.

The lower surface of the shell body is provided with second bulges which are distributed annularly; the second bulge is abutted to the upper surface of the sucker. When the first spring exerts force on the shell, the second bulge is abutted to the sucker to extrude the space between the sucker and the floor, so that the effect of further exhausting is achieved, the suction force of the sucker is improved, and the anti-skidding capacity of the desk is further improved.

The upper surface of the sucker is also provided with a lifting part, and the lifting part is positioned on the outer side of the shell. When the desk needs to be moved, the lower end of the sucking disc can be easily lifted only by pulling the lifting part, so that air enters the bottom of the sucking disc, and the sucking disc is easily separated from the floor.

The pressing mechanism comprises a baffle and a second spring; the baffle is annular; the baffle is fixedly arranged on the stud, and the second spring is sleeved on the stud; the baffle is arranged between the cross beam and the wrench, and two ends of the second spring are respectively abutted against the baffle and the cross beam. The second spring is arranged between the baffle and the cross beam, the second spring generates force towards two ends after being extruded, the cross beam is fixed, the baffle is fixedly arranged on the double-screw bolt, downward force can be applied to the double-screw bolt, the double-screw bolt is prevented from driving the sucker to move upwards, the sealing performance of the sucker is further improved, the suction force of the sucker is improved, and the anti-skidding capacity of the desk is further improved.

The stud and the sucker are integrally formed. Therefore, the sealing performance of the sucker can be ensured, and the assembly is convenient.

The positive progress effects of the invention are as follows: the suckers at the table legs are sucked on the floor of a classroom, so that the desk has an anti-skid function and cannot damage the floor; after force is applied to the wrench, the shell can be extruded on the sucker, so that the sealing performance of the sucker is improved, air leakage is avoided, and the anti-skid performance of the desk is further improved; by adjusting the stud, the suction cup can be quickly sucked on the ground or separated from the ground.
