It is worth noting that the limiting rod 16 and the abutting block 19 are made of steel materials, so that the limiting rod 16 is prevented from being stressed and deformed to influence the firmness of the limiting rod, the first-stage bolt 11 and the second-stage bolt 12 are made of silica gel materials, and silica gel filled in a gap between the first-stage bolt 11 and the second-stage bolt 12 has a buffering effect and can be deformed randomly when being subjected to external force.

Wall body 1 adopts the flat plate structure, and wall body 1 overall height is 7-9cm, the interval is 3-4.5cm between 9 lower extremes of plastic backing plate and the 14 upper ends of layer board, nine root sleeve pipes 2 adopt the equidistance distribution of triplex row three rows, in order to adapt to the curved surface pad 8 in the different atress condition of different positions, and horizontal pole 5 quantity is nine, nine horizontal poles 5 level respectively run through the cover and locate in long chamber 3, and

horizontal pole

5 and 3 clearance fit in long chamber, curved surface pad 8 corresponds with nine bearing plates 7 on being close to one side of telescopic link 6 and has seted up nine recesses, and nine bearing plates 7 respectively with embedded in nine recesses, and bearing plate 7 bonds through the powerful glue with the recess.

The upper end face of the plastic cushion plate 9 is of an inclined structure, the middle end of the plastic cushion plate 9 is provided with a U-shaped groove 13, the U-shaped groove 13 is convenient for limiting the arm, the falling off of the anti-pressing and relieving device due to the movement of the arm is avoided, a silica gel plate is connected between the upper end face and the two side faces of the curved cushion 8 and the plastic cushion plate 9, the first-stage bolts 11 and the second-stage bolts 12 are distributed in an interlaced and equidistant mode, and silica gel is filled between the first-stage bolts 11 and the second-stage bolts 12.

The sucking disc 17 is located layer board 14 top, and second grade spring 18 is located layer board 14 lower extreme, and second grade spring 18 lower extreme welds mutually with supporting piece 19, and second grade spring 18 upper end offsets with layer board 14 lower extreme, and accessible second grade spring 18 opens and shuts the effort and drive sucking disc 17 and adsorb with the table along the lower extreme and be connected, just helps promoting its stability.

The working principle of the invention can be realized by the following operations:

firstly, the limiting rod 16 is pulled downwards by manpower, the limiting rod 16 slides downwards in the through cavity 15, meanwhile, the sucker 17 is propped against the upper end face of the supporting plate 14 under the driving of the limiting rod 16, at the moment, the secondary spring 18 is stressed and stretched, when the table edge thickness is determined to be clamped between the plastic cushion plate 9 and the supporting plate 14, the limiting rod 16 is loosened, under the driving of the condensation acting force of the secondary spring 18, the limiting rod 16 vertically rises in the through cavity 15, meanwhile, the sucker 17 is driven to rise, so that the sucker 17 is adsorbed on the lower end face of the table edge, at the moment, the lower end face of the plastic cushion plate 9 is attached to the table top, the outer wall of one side of the wall body 1, which is far away from the sleeve 2, is tightly propped against the table edge, and therefore the anti-collision relieving device.

In the working and learning process, the arms can be placed on the plastic cushion plate 9, and it is noted that the arms can be placed in the U-shaped grooves 13, the arms can be relatively fixed in the U-shaped grooves 13, and the plastic cushion plate 9 is connected with the upper ends of the wall body 1 and the curved surface cushion 8 through the silica gel plate, so that a gap is formed between the arms when the arms are in contact with the device, and the arms are completely attached to the device.

When the arm is to the application of force to plastic backing plate 9, thickened plate 10 carries out the gravity extrusion to second grade bolt 12, make second grade bolt 12 lower extreme deepen gradually in the gap between the one-level bolt 11, meanwhile, second grade bolt 12 is when extrudeing one-level bolt 11, silica gel also produces plastic deformation and produces the motion in plastic backing plate 9, carry out the support of reverse effort to second grade bolt 12 through one-level bolt 11, thereby support 19 grades of plastic backing plates 9 upper ends of thickening pad through second grade bolt 12, utilize the different positions of arm to the difference of the dynamics of second grade bolt 12, thereby make thickening pad 10 and plastic backing plate 9 produce the sunken or protruding of different degrees, in order to adapt to the arm structure, thereby provide comparatively soft support for the arm, avoid desktop and table to cause the strangling mark along transition department to the arm.

When a user has a rest, part of the users are used to prop legs against the edge of the table, at the moment, the legs can be attached to the curved surface pads 8, when the legs apply pressure to the curved surface pads 8, the curved surface pads 8 extrude the nine bearing plates 7, the bearing plates 7 prop against the telescopic rods 6, the corresponding cross rods 5 are further extruded, and the cross rods 5 horizontally slide in the long cavities 3 in the sleeves 2 due to stress, so that the primary springs 4 are compressed; meanwhile, under the tension effect of one-level spring 4 to carry out reverse support to horizontal pole 5, telescopic link 6 and bearing plate 7, thereby fill up 8 not applied not equidimension external force of position to the curved surface according to the shank and warp the support, help curved surface pad 8 to carry out inseparabler laminating support to the shank, curved surface pad 8 avoids shank and table to follow directly offset, thereby carries out elastic support to the shank.

It should be noted that, in this prevent pressing against and relieve device, wall body 1, bearing plate 7, curved surface pad 8, plastic backing plate 9, thickening pad 10, one-level bolt 11 all adopt the silica gel material with second grade bolt 12, as long as the composition is silica, its stable nature has fire behavior, and difficult water-soluble has certain gentle degree, suitable being used for preventing pressing against and relieve the device.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
