Description

Workbench supporting structure

Technical Field

The utility model belongs to the technical field of the workstation supports, in particular to workstation bearing structure.

Background

The supporting part of the workbench is basically divided into a fixed part and a foldable part, the foldable structure is divided into a lockable part and an unlockable part (the locking means that the supporting part can be locked and fixed in the supporting state so as to bear certain transverse external force and ensure more stability, and the supporting part can be limited in a folded state during storage so as to be more convenient to move), and the foldable workbench disclosed by the authorization notice number CN212671108U has the function of being locked in the folded and unfolded states, but the supporting part has more combined parts, more hinge points and inconvenient unlocking; there is another foldable work table disclosed in the publication No. CN204743078U, which has a simple support structure but no locking function, and has insufficient stability of support when in use.

Disclosure of Invention

To the defect that above-mentioned prior art exists, the utility model aims to solve the technical problem that a workstation bearing structure is provided, the part of this structural grouping is few relatively, enables the workstation of using and is convenient for fold to for automatic locking when supporting with accomodating, consequently it is more convenient to use.

The invention aims to be realized by the following technical scheme: a supporting structure of a workbench comprises a supporting pillar piece, a sliding rod, a self-locking assembly and an unlocking assembly, wherein the sliding rod is transversely and rotatably arranged at the upper end of the supporting pillar piece; the sliding rod can slide relative to the self-locking assembly and the unlocking assembly, and the support column piece is in a storage state when the sliding rod slides to one end and is in a supporting state when the sliding rod slides to the other end.

Preferably, the self-locking assembly comprises two lock tongues which are arranged in the same direction as the folding direction of the support column piece, a lock tongue mounting seat for mounting the lock tongues, a compression spring arranged in the lock tongue mounting seat and used for pushing the lock tongues outwards, and a slide rod locking seat capable of locking the slide rods together with the lock tongues. The inclined planes of the two lock tongues face to the center of the unlocking assembly, the self-locking assembly is locked to be kept in a normal state through the two opposite lock tongues and the compression spring at the lower part of the lock tongues, and the locking mode is free of manual operation and convenient and fast to use.

Preferably, the slide bar locking seat is integrally rectangular in a box shape, waist-shaped holes are formed in two side faces in the length direction of the box body, the diameter of each waist-shaped hole is equal to that of the slide bar, the length of each waist-shaped hole is set to be the stroke of the slide bar between unfolding and folding of the support column, the two lock tongue inclined planes are inwards arranged at two ends of each waist-shaped hole, and one diameter of the slide bar is reserved between one straight edge side of each lock tongue and the farthest arc face of each waist-shaped hole. The specific positions of the sliding rod to be locked, namely the position of a folded state and the position of an unfolded state, are determined through the design of the sliding rod locking seat, and after unlocking, the sliding rod is switched between the two positions without other operations and only needs to be pulled to normally do folding or unfolding actions.

Preferably, the unlocking assembly comprises an unlocking member disposed in the slide bar lock seat. The unlocking piece is arranged in the sliding rod locking seat in a concealed mode and does not only occupy the used space.

Preferably, one end of the unlocking piece is exposed, the other end of the unlocking piece is sleeved in the sliding rod locking seat in a sliding manner, and the exposed end is arranged as the unlocking pressing part. Only the pressing part is exposed, thereby being convenient for operation.
