Description

BACKGROUND OF THE INVENTION

Field of the Invention:

[0001] The present invention relates to an improved frame of a partition plate of a storage rack for solving disadvantages generated when the frame of a conventional partition plate is welded with a sleeve tube; the present invention utilizes concave slots formed at corners defined at a top and a bottom folding sheets of a frame for accommodating a sleeve tube, thereby enabling the frame to be combined with the sleeve tube with an ultrasonic welding means.

2. Description of Related Art:

[0002] The structural design for a conventional metal storage rack as such as a wave-shaped rack is shown in FIG. 1 and FIG. 2, at least four vertical posts (10) are installed, and the peripheral circumference of each of the posts (10) is formed with a plurality of annular concave slots (11) spaced with an equal interval, plastic sleeve members (12), (13) are provided for being selectively sleeved for the purpose of combination, ribs (14) formed at inner edges of the plastic sleeve members (12), (13) are served to be mounted and latched in the annular concave slots (11) of the post (10) for obtaining an initial positioning relation, and with the conical design for the plastic sleeve members (12), (13) and the inner conical design for sleeve tubes (21) at four corners of a partition plate (20), the partition plate (20) and the posts (10) are enabled to be stably positioned and combined through the plastic sleeve members (12), (13) being positioned, and the above-mentioned partition plate (20) is mostly formed through welding a plurality of metal strips so as to form a grid-like carrying surface (22), meanwhile a frame (23) of the partition plate (20) is also formed through welding one or a plurality of metal strips and decorative strips for providing a better structural strength, so an effect of allowing objects to be places is achieved; moreover, the skilled people in the art have also developed a metal lath sheet for replacing the grid-like surface, thereby preventing small objects from falling through gaps formed between grids.

[0003] However, no matter a grid-like design or a metal lath sheet is adopted as the carrying surface of the partition plate, the assembly of the partition plate and the sleeve tube of the vertical post is achieved by a welding means, in other words four corners of the frame of the partition plate are respectively formed with a notch or a concave slot for allowing the additionally-made sleeve tube to be installed, then a welding agent is provided for the purpose of welding and positioning so as to finish the assembly of the partition plate and the sleeve tube, and with the conical design for the inner diameter of the sleeve tube, the sleeve tube is able to form a positioning relation with the plastic sleeve member after the sleeve tube is sleeved on the vertical post, and the distance defined between two adjacent partition plates can be adjusted according to the actual needs.

[0004] However, because the frame of the partition plate and the sleeve tubes at four corners are combined with a welding means, unattractive welding marks may be formed and the appearance may be affected, and the whole quality may depend on the technical level and experience of an operator who is in charge of the welding operation; in addition, the whole operation procedure is complicated, thus the disadvantages existed in prior art shall be improved.

SUMMARY OF THE INVENTION

[0005] In view of the conventional storage rack having the frame and the sleeve tubes at four corners being welded for assembly which may cause the disadvantages such as the process is time consuming, the quality is uneasy to be controlled and the appearance may be affected by welding marks, the applicant of the present invention has devoted himself for inventing a novel design for improving the above-mentioned disadvantages, thus an improved frame of a partition plate is provided

[0006] The present invention is aimed to solve the disadvantages generated when the frame of a conventional partition plate is welded with a sleeve tube; accordingly, the present invention provide a design that the top and the bottom edge of a frame of a partition plate is respectively folded for forming a horizontal folding sheet having a predetermined width, and four corners thereof are respectively formed with a concave slot respectively allowing an additionally-made sleeve tube to be sleeved therein, and the dimensions of the concave slots formed on the top and the bottom folding sheets are matched with the conical status of the sleeve tube, so after the sleeve tubes are respectively sleeved at the four corners of the frame, an ultrasonic welding operation is able to processed for welding the frame and the sleeve tubes, thereby achieving an effect of stably combining without forming any welding mark.

[0007] The present invention is aimed to improve the assembly of a frame of a partition plate of a storage rack and sleeve tubes at four corners thereof, in which an ultrasonic welding means is adopted for replacing the conventional welding means, so the operation can be simplified, the structural stability can be greatly enhanced, and no unattractive welding mark is formed, thereby allowing the whole appearance and quality to be improved; accordingly, the present invention is novel and more practical in use comparing to prior art.
