Description

Workbench column

This disclosure is about a workbench column, especially a workbench column with protection and decoration parts.

A typical working table, such as a medical operating table, generally has a base and a working table column on which the lifting unit is arranged, and a working platform is provided on the top surface of the working table column (lifting unit) to accommodate the surgical patient and related Surgical instruments, medical supplies or medicines and even medical records. For the sake of beauty, hygiene and convenience of cleaning, a decorative plate (tube) is generally placed to cover the lifting unit.

The conventional fixing methods of the workbench column trim (cylinder) are all fixed by screw locking. However, if the bolt has a nut, if it protrudes from the surface of the decorative plate (tube), it will not only increase the joint of the decorative plate (tube), but also affect the overall visual beauty, and require additional space and structure to hide it. In addition, the bolts are locked by means of thread locking, which is not easy to disassemble and assemble, and is relatively time-consuming to assemble.

Therefore, there is a need to provide an advanced workbench column to solve the problems faced by conventional technology.

An embodiment of the present specification provides a workbench column. The workbench column includes: a lifting unit, a first trim panel, a second trim panel, a first fitting, and a second fitting. The lifting unit has a lifting direction. The first trim panel has a first surface and a first side wall connected to the first surface. The second trim panel has a second surface and a second side wall connected to the second surface. The first fitting member is fixed on the first surface and partially extends outward beyond the first side wall. The second fitting is fixed on the second surface and is adjacent to the second side wall for engaging with the first fitting, so that the first surface and the second surface surround the elevator unit together.

According to the above-mentioned embodiment, the embodiment of the present specification provides a workbench column with a lifting unit. Adopt the way of fitting pieces to fix, at least two trim plates are snapped together to form at least one trim tube surrounding the lifting unit, so as to save the number of parts (screws), shorten assembly time and ensure that the trim tube will not fall off when moving The purpose of the smooth operation of the workbench column.

In some embodiments, the table column includes a plurality of decorative cylinders coaxially sleeved with each other, and combined with each other in a movable manner, and cooperates with the lifting of the lifting unit, and relatively moves along the lifting direction of the lifting unit, to Make a plurality of decoration cylinders present the appearance of stretching and condensation. A hook piece can be used to limit the connection between the two upper and lower adjacent decoration tubes, so that the decoration tube still maintains the coaxial sleeve state when it shows a stretched appearance.
