Improved Structure of Laminates of Pillar Sleeve Combination Frame

technical field

The utility model relates to a laminate structure of a column sleeve type combined frame.

Background technique

In the traditional column-sleeved combination frame (please refer to Fig. 1 and Fig. 1-A), because the laminates 2 placed at intervals in each layer are simply matched with pitch-shaped positioning concave rings 31, and the height can be adjusted. The assembled side column 3 and the two-piece positioning clip 4 are pre-selected on the concave ring 31 of the side column 3. After the relative clamping position is selected, a ring-shaped limit sleeve 22 is provided at the corner position, and the downward sleeve is provided. The positioning of the laminate 2 can be achieved by staying on the periphery of the positioning clip 4; its structure is convenient for disassembly, assembly and position adjustment, that is, it is widely used in product display in stores or multi-layered storage in homes.

However, the laminate 2 of this post-sleeved combination frame is made of structure (please still refer to shown in Fig. 1), it is at first welded connecting rods 213 (usually made into waves) with metal wire rods on the upper, The middle sections of the lower support frame rods 211, 212 are made into side panels 21; and the hollow conical spacer sleeves 22 that are small at the top and large at the bottom provide two adjacent side panels 21 above and below each end. A welding point P is welded to form a frame 2A; and then the supporting surface 23 (usually straight or mesh-shaped connecting rods to form a mesh surface) is fixed and connected to the inner periphery of the top side of the frame 2A to complete the production of the laminate 2. The shortcoming of this layer plate 2 structure is firstly that the forming and making of the hollow conical spacer sleeve 22, materials, etc. all consume more cost; By means of multi-point welding, each rectangular laminate 2 basically has four sleeves 22, that is, there are at least sixteen welding points. In addition to the disadvantages of cumbersome welding procedures and high processing costs, such a structure Welding accuracy, fastness requirements, etc. are all potential factors for the high price, difficulty in manufacturing, and high defect rate of finished products of this type of laminate structure.

Detailed ways

First of all, please refer to Fig. 2 and Fig. 2-A as shown in Fig. 2-A: the structural improvement of the laminate 5 of the column sleeve type combination frame in this case is mainly composed of two-by-two sets of ring-shaped limit sleeves 51A and 51B, which are respectively installed in the The rectangular or polygonal corner positions formed by the fixed connection of metal wires constitute the laminate 5;

Among them, each group of ring-shaped limit sleeves 51A, 51B is formed by a ring made of metal wire, and the upper part is small, the lower part is larger, and the same axis is symmetrically arranged, thereby providing the upper and lower support rods 521, 522 with metal rings. The side piece 52 formed by the fixed connection of the wire welding connecting rod 523 (usually made into a wave shape) is used to weld and fix the upper and lower welding endpoints P1 and P2 on both sides to form a relay sleeve for two adjacent side pieces 52 turning at right angles. Connect, thereby linking into a rectangular or polygonal laminate 5 frame 5A; thus the frame 5A is then fixedly connected to the object-bearing surface 53 (usually a straight or mesh connecting rod, forming a mesh surface) through the inner circumference of the top side, The production of laminate 5 can be completed;

In this way, each set of upper and lower ring-shaped limit sleeves 51A, 51B with fixed inner circumference specifications provides side columns 3 with pitch-shaped positioning concave rings 31, and cooperates with two-piece positioning clips 4 in the concave ring 31. After the upper pre-selection of the relative clamp, the lower large-size limit sleeve 51B is inserted from top to bottom, and the positioning clamp can not be disengaged or displaced due to the inner circumference of the limit sleeve 51A and 51B. Sheet 4 becomes a stop assembly that provides clamping and positioning of the upper small size limit sleeve 51A; thus, the ring-shaped limit sleeves 51A, 51B that are configured symmetrically with the same axis center are sufficient to replace the existing structure 1. The larger hollow conical spacer sleeve 22 (shown in FIG. 1 ) achieves the practical and economic benefits of simplifying the manufacturing process and effectively reducing the manufacturing cost, which is its feature.

Please refer to Fig. 3 and Fig. 3-A, Fig. 3-B, and Fig. 3-C in conjunction with the continuation: the structural improvement of the laminate 6 of the column sleeve type combined frame in this case is made of metal wires at the corners of the laminate 6. The ring-shaped limit sleeves 61A and 61B (please refer to Fig. 4 for cooperation) can be formed by automatic and continuous machine tools for continuous ring making and turning of metal wires, and welding at the end point P3 at the end of the last ring , respectively make the whole section single-rod type upper section frame 6A which continuously includes the upper support frame rod 621 of each section and the smaller ring-shaped limit sleeve 61A, and continuously includes the lower support frame rod 622 of each section and the larger ring-shaped limit sleeve 61B's full-section single-rod lower frame surrounds 6B;

Then, between the upper and lower support frame rods 621 and 622 of the upper and lower frame enclosures 6A and 6B, the connecting rod 623 (usually made into a wave shape) is welded with a metal wire, and the upper frame enclosure 6A is then fixed through the inner circumference. Connecting the supporting surface 6C (usually straight or mesh-shaped connecting rods to form a mesh surface), it can be made into a laminate 6 structure with the upper and lower limit sleeves 61A and 61B symmetrically arranged on the same axis;

In this way (please refer to Fig. 5 for cooperation), the upper and lower ring-shaped limit sleeves 61A, 61B of each group of fixed inner circumference specifications can provide the same side column 3 that is provided with a pitch-shaped positioning concave ring 31, and cooperate with the two After the piece-type positioning clip 4 is pre-selected on the concave ring 31 and the relative sleeve is clamped, the lower large-size limit sleeve 61B is inserted from top to bottom to fit, so that it can be placed in the limit sleeves 61A and 61B. The positioning clip 4, which cannot be disengaged or displaced, becomes a stop assembly that provides the clamping and positioning of the upper small size limit sleeve 61A; thus, the laminate 6 has the upper and lower frame circumferences 6A, 6B and only single welding The strongest and simplest structure of the point can significantly reduce the welding operation requirements in the manufacturing process, achieve the excellent economic efficiency of greatly improving manufacturing efficiency and reducing manufacturing costs, which is another important feature of this project.

The above description is only illustrative, rather than restrictive, of the present utility model. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the claims. But all will fall within the limitable scope of the claims of the present utility model.
