BRIEF DESCRIPTION OF DRAWINGS

[0016] Fig. 2 It is the upside-down three-dimensional structure diagram of the stool embodiment inserted with one height increasing piece. DETAILED DESCRIPTION

[0017] The utility model will be further explained in connection with the drawings.

[0018] As attached Figs. 1-2 The utility model discloses a plug-in type height adjusting workstation board stool stool foot, including stool body 1, height increasing piece 2 and foot pad 3, the lower part of stool body 1 and height increasing piece 2 can insert foot pad 3, any height increasing piece 2 can be inserted in the lower part of stool body 1, and two height increasing pieces 2 can be inserted upside down, wherein height increasing piece 2 as a kind of universal plug-in piece, main part can be provided with multiple height dimensions, to meet the different height increasing demand of stool.

[0019] Two high pieces can be inserted up and down to each other, and the stacked combination of multiple high pieces can be inserted to meet the demand of height adjustment more flexibly. On the other hand, the size of a single high component can be further reduced, and the demand of larger height adjustment can be realized by the combination of more high pieces, which can further reduce the occupied space of the standby storage.

[0020] Preferably, the stool body and the high piece are integrally injection molded by polypropylene (PP) engineering plastic, which has excellent properties such as non-toxicity, environmental protection, antibacterial, aging resistance, etc. The overall structure is light and the relative cost is low, which is more suitable for workstations. The foot pad can be made of special TPV material, which has good anti-skid effect and good wear resistance and corrosion resistance in complex working environment, and has a longer service life.

[0021] On this basis, since the stool body and the high piece integrally formed by plastic material have a box-shaped thin-walled structure, and the stool mainly contacts the ground through the foot pad, and the foot pad plays a major role in bearing, the interface for inserting the foot pad 3 in the stool body 1 and the high piece 2 is provided with a longitudinal stress component 4, and the stress component 4 forms a supporting force on the inserted part of the foot pad 3. By setting the longitudinal stress component in the interface for inserting the foot pad, the force transmitted from the stool surface to the foot pad through the stool is mainly transmitted to the foot pad through the stress component, thereby avoiding the deformation of the outer thin wall of the stool body 1 and the high piece 2 due to the bearing pressure, ensuring the structural stability of the stool body and the high piece, enhancing the durability, and prolonging the service life.

[0022] The interface for inserting the foot pad 3 in the stool body 1 and the high piece 2 is a first insertion interface 5, and the upper part of the high piece 2 is provided with a support block 21, which can be inserted into the first insertion interface 5 and contact the stress component 4. When the lower part of the stool body is inserted with one or more high pieces, the stress transmission between the stool body and the high piece or the stress transmission between the adjacent two high pieces is effected by the corresponding stress component 4 acting on the corresponding support block 21, and the stress component of the bottommost high piece acts on the foot pad, thereby forming the main bearing structure of the spliced stool with the bottommost foot pad by the multiple sets of stress components 4 and support blocks 21, so that the outer thin wall of the stool body 1 and the high piece 2 can avoid deformation due to bearing pressure, thereby having stability, reliability and durability when adjusted to any height.

[0023] The support block 21 on the upper part of the high piece 2 is aligned with the first insertion interface 5 on the lower part, so that the force between the stress component 4 and the support block 21 is vertically transmitted longitudinally.

[0024] The inner contour size of the first insertion interface 5 is larger than the outer contour size of the support block 21. The support block 21 is only subjected to longitudinal pressure, plays a major supporting role, and is not interfered by stress in other directions, further ensuring the stability of the stool structure and avoiding deformation of the stool structure.

[0025] The upper part of the heightening member 2 is provided with an embedded block 22. The stool body 1 and the heightening member 2 are used to insert the interface of another heightening member 2 as a second insertion interface 6. The embedded block 22 can be inserted into the second insertion interface 6 and transversely fitted and embedded. Unlike the support block 21, the embedded block 22 is only subjected to horizontal pressure and is mainly subjected to longitudinal static friction, plays a role in maintaining the vertical alignment of the stool body and the plurality of heightening members, avoids lateral misalignment or lateral bending of the stool after insertion and heightening, and further maintains the stability of the stool structure. In order to avoid the interference of longitudinal pressure, a sufficient gap is left between the upper end surface of the embedded block and the upper end surface of the second insertion interface. In summary, the support block 21 and the embedded block 22 respectively play the roles of longitudinal load bearing and fastening connection.

[0026] Preferably, the stool body 1 is provided with two first insertion interfaces 5, and the two first insertion interfaces 5 are respectively located at the two ends of the lower part of the stool body 1. The downward pressure transmitted by the stool can be dispersed to the two ends, the load bearing capacity of the stool is improved, the stool is not easy to be damaged under pressure, and the stool has higher reliability and stability. In addition, the contact area of the foot pad with the ground is reduced, which achieves the effect of preventing slipping and does not make the stool difficult to move. Usually, the stool is installed at the two ends of the load bearing beam in the length direction of the stool, and the length direction of the stool is perpendicular to the length direction of the stool. According to the sitting habit of employees, they usually tend to one side in the width direction of the stool, which will cause the foot pad on the sitting side to be more seriously worn. The foot pad is arranged at the two ends, and when the stool is too inclined due to serious wear, only the foot pad on the side with serious wear needs to be replaced.

[0027] Preferably, the plurality of the inserts 22 are arranged between the two support blocks 21. The connection between the upper and lower inserts can be further stabilized, and the relative position of the middle structures of the two is further constrained and limited, so as to avoid horizontal lateral bending deformation. When the stool leg body and the heightening component are integrally injection molded by polypropylene (PP) engineering plastic, the second insertion interface 6 and the insert 22 are respectively a thin-walled groove and a protruding structure, and the end profiles of the two can be correspondingly provided in a circular or square shape, and the corners are appropriately rounded to reduce the insertion resistance. Since the plastic part has a certain toughness and elasticity, when the insert 22 is inserted into the second insertion interface 6, a certain deformation occurs, thereby generating an interference fit effect. The protruding structure and the corresponding groove structure generate vertical mutual friction resistance, and also generate horizontal extrusion force. A single insert 22 exerts a ring-shaped force on the groove wall from the inside, and the adjacent two inserts 22 clamp the groove wall therebetween. The insertion strength between the heightening component and the stool leg body or between two heightening components is greatly improved, and when a person sits, the fitting relationship becomes tighter, and the thin-walled protruding structure expands outward when subjected to pressure, thereby generating greater locking force on the inserted groove wall, so that the stool leg structure is more stable.

[0028] Preferably, the stress component 4 is a cross-shaped reinforcing rib. The two reinforcing ribs are orthogonal to each other, and the intersection point is located at the center of the first insertion interface 5. When the stool leg body and the heightening component are injection molded parts, the support block 22 is a thin-walled protruding structure, the lower cavity thereof is in communication with the inner cavity of the first insertion interface 5 at the bottom side, and the upper end of the stress component 4 directly extends upward to be integrated with the lower cavity of the support block 22, thereby forming a more stable bearing structure.

[0029] In addition, a threaded counterbore can be arranged at the center of the cross-shaped reinforcing rib at the lower part of the stool leg body, a through hole can be arranged at the lower part of the cross-shaped reinforcing rib of the heightening component, and a through hole can also be correspondingly arranged at the center of the foot pad. When a plurality of heightening components are simultaneously inserted, the through holes on the foot pad and the through holes on the plurality of heightening components are aligned with the threaded counterbore at the lower part of the stool leg body, so that a long bolt can be inserted from the bottom center hole of the foot pad, sequentially penetrate through the plurality of heightening components, and finally be screwed with the threaded counterbore at the lower part of the stool leg body. Thus, the plurality of stress components 4, the plurality of support blocks 21, and the foot pad are connected to form an integral whole and are screwed and fixed at the lower part of the stool leg body. The connection strength is further improved on the basis of the original insertion, and the longitudinally arranged stud additionally functions as a core bearing part. Compared with the stool leg body and the heightening component, the metal material has stronger bearing capacity. The reliability and stability of the stool leg are further ensured.

[0030] The above are only preferred embodiments of the present application, and it should be pointed out that: for ordinary skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered the same as the scope of the present application.
