High-strength working table

Abstract

Disclosed is a high-strength working table. The high-strength working table comprises a table surface and two ladder pillars hinged to the two ends of the table surface. Hinged points of the ladder pillars and the table surface are located on a side profile of the table surface. The two end parts of the table surface are sealed through an end cover structure. The end cover structure includes an end cover profile and a connecting piece. The inner side surface, facing the table surface, of the end cover profile is horizontally provided with a reinforced transverse rib. The reinforced transverserib and the bottom surface of the table surface are attached and fixed. A reinforced strip is fixedly arranged in the middle of the bottom of the table surface. Each ladder pillar is provided with anunlocking structure. Each unlocking structure comprises an operation knob, a rotating lock tongue and a first elastic part. The rotating lock tongues are rotationally arranged in a stand column, the upper ends of the rotating lock tongues are provided with locking hooks, and the locking hook locks a lock piece located at the bottom of the table surface. The first elastic parts act between the rotating lock tongues and the stand column and drive the locking hooks to be positioned towards the lock piece to achieve locking of the ladder pillars and the table surface. The operation knobs act on the rotating lock tongues and drive the locking hooks to move in the opposite direction of the lock piece to achieve unlocking of the ladder pillars and the table surface. The high-strength working table has practical progressive performance such as high table surface structural strength, low thickness after being folded and convenient unlocking operation.

Description

technical field [0001] The invention relates to a folding workbench for climbing work, in particular to a high-strength workbench. Background technique [0002] The workbench, also known as the workbench, is a commonly used tool for climbing work. It is mainly used to provide a work platform above the ground for the user to stand on, so as to facilitate operations such as car washing. The workbench can be used not only indoors, but also outdoors, and can be used for car washing, decoration, maintenance, picking up and storing things, etc. [0003] like figure 1 , 2 As shown, the existing workbench usually includes two ladder columns 1 and a table top 2, the upper ends of the two ladder columns 1 are respectively hinged below the front and rear ends of the table top 2, and the table top 2 is used as a working surface for use The person stands; the bottom of the table 2 is provided with several crosspieces 3 at intervals in parallel along its length direction, which is used...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the existing unlocking structure 5 is arranged on the side of the table top 2 in the width direction, on the one hand, the user does not operate smoothly when unlocking it; , sometimes directly lead to damage to the unlocking structure 5, causing the workbench to be unable to be unlocked;

[0006] 2. The overall structural strength of the table top 2 needs to be guaranteed by multiple crosspieces 3. There are problems with the large number of crosspieces 3 in the existing structure, which leads to an inability to reduce costs and many assembly processes;

[0007] 3. In order to prevent the ladder columns 1 from overlapping each other after being folded, the folded thickness of the workbench is reduced to increase the packing capacity during shipment. Therefore, without reducing the height of the ladder columns 1, it is necessary to adjust the length of the table 2 The extension was carried out, but the middle part of the extended table top 2 had poor stress and could not pass the stress test;

[0008] 4. The hinge point of the ladder column 1 and the table top 2 is relatively high, that is, the hinge point is not on the same plane as the table top 2, but has a certain distance from the side of the table top 2 in the height direction, so that the ladder column 1 is retracted Finally, it cannot be completely attached to the table 2, which makes the thickness of the workbench too large, which affects the packing volume during shipment
