background
the working platform is also called as a working platform, is a common working tool for ascending height, and is mainly used for providing a working platform higher than the ground for a user to stand so as to conveniently carry out operations such as car washing and the like. The workbench can be used indoors and outdoors, and can be used for washing, decorating, maintaining, fetching, placing objects and the like.
As shown in fig. 1 and 2, the conventional work bench generally includes two ladder posts 1 and a table top 2, wherein the upper ends of the two ladder posts 1 are hinged below the front end and the rear end of the table top 2, respectively, and the table top 2 serves as a work surface for a user to stand; the bottom of the table top 2 is provided with a plurality of crosspieces 3 at intervals along the length direction thereof in parallel for enhancing the structural strength of the table top 2, the number of the crosspieces 3 is in direct proportion to the length of the table top 2, and three and four are common; both ends of the table top 2 in the longitudinal direction are sealed by a cap structure 4.
Two ladder posts 1 of current workstation all are equipped with an unlocking structure 5 with the pin joint of mesa 2, through the state of opening or folding up of two ladder posts 1 of this unlocking structure 5 locking workstation, perhaps two through this unlocking structure 5 unblock ladder post 1 makes it rotate in the below of 2 tip on mesa. The problems existing in the prior art are as follows:
firstly, because the existing unlocking structure 5 is arranged at the side part of the width direction of the table top 2, on one hand, the operation of a user is not smooth when unlocking, on the other hand, the user often collides with the unlocking structure 5 carelessly in the transportation and use processes of the workbench, sometimes, the unlocking structure 5 is directly damaged, and the workbench cannot be unlocked;
secondly, the overall structural strength of the table top 2 needs to be ensured by a plurality of crosspieces 3, and the existing structure has the problem of large number of the crosspieces 3, so that the cost cannot be reduced and the number of assembly processes is large;
in order to prevent the ladder columns 1 from being overlapped after being folded, the folding thickness of the workbench is reduced to improve the packing amount during shipment, so that the length of the table top 2 needs to be prolonged under the condition that the height of the ladder columns 1 is not reduced, but the middle part of the table top 2 after being prolonged is poor in stress and cannot pass a stress test;
Fourth, the hinge point position of halfpace 1 and mesa 2 is higher, and the hinge point is not on the coplanar with mesa 2 promptly, but has certain distance in the lateral part of direction of height and mesa 2 to lead to halfpace 1 can not laminate in mesa 2 completely after the folding, make the thickness of workstation too big, the vanning volume when influencing the shipment.
Therefore, how to solve the above-mentioned deficiencies of the prior art is the subject of the present invention.
