Positioning device and combined article rack with positioning devices

Abstract

The invention relates to a combined article rack with positioning devices, and the combined article rack provided by the invention comprises a plurality of support units, a plurality of the positioning devices and an article placing unit. Each support unit comprises four supporting rods which are spaced mutually and a plurality of connecting rods mounted and fixed among the supporting rods. Each positioning device comprises a clamping seat and an outer sleeve seat, each clamping seat comprises two inner clamping parts which are relatively clamped outside two supporting rods and one connecting rod, and each outer sleeve seat is sheathed and positioned outside the clamping seat. The article placing unit is mounted and fixed among the outer sleeve seats. Therefore, the combined article rack has the characteristics of being convenient and fast for assembly and detachment.

Description

technical field [0001] The invention relates to a storage rack, in particular to a positioning device and a combined storage rack with the positioning device. Background technique [0002] Such as figure 1 , figure 2 , image 3 As shown, the combined shelf 10 of Taiwan Announcement No. 437341 "Structure of the Combined Shelf" has several vertical pipe fittings 11, several clips 12, several horizontal mesh layers 13, and several collars 14. [0003] Each upright pipe 11 has two first side walls 111 and two second side walls 112 parallel to each other, several equidistant horizontal through grooves 113 arranged on the first side walls 111, and arranged on the first side walls 111. Two upright recesses 114 of the second side wall 112 are described. [0004] Each clip 12 has a connection block 121 located on the outside of the first side wall 111 respectively, and two wing blocks 123 bent from the connection block 121 and provided with a connecting ligament 122 are formed f...

AI Technical Summary

Problems solved by technology

[0007] 1. Inconvenient assembly: because the insert 125 is relatively bent from the wing 123 and partially protrudes into the recess 114, and the width L of the opening 141 of the collar 14 is smaller than that of the vertical pipe 11 passing through the The diameter H of the collar 14 is such that when assembling, the collar 14 must be inserted from the top of the vertical pipe 11, and placed outside the corresponding clip 12, and must be arranged from bottom to top. Assembly

Therefore, when assembling the horizontal mesh layer 13 of the upper layer, it will cause inconvenience in operation for users or women who are shorter in stature.

[0008] 2. Inconvenient height adjustment: when you want to adjust the height of the horizontal mesh layer 13 in the middle, you must push the horizontal mesh layer 13 upwards by one person to make the collar 14 break away from the clip 12, and wait for another person to adjust it. When the clip 12 is at a high or low position, the horizontal mesh layer 13 is put down again, so that the collar 14 is placed outside the clip 12 again, and the operation process is very inconvenient.

[0009] 3. Inconvenience caused when wanting to increase the number of net layers or reduce the number of net layers: no matter whether the user wants to increase or reduce the quantity of the horizontal net layer 13, he must first remove all the horizontal net layers 13 above the predetermined position , another horizontal net layer 13 can be inserted or taken out through the top of the vertical pipe fitting 11, and the operation process is also very inconvenient

[0010] 4. Inconvenience during production: because the cross-section of the vertical pipe 11 is polygonal and special-shaped, it must go through multiple roller processes before it can be manufactured. The production cost is relatively high, and the manufacturer must use the upper and lower molds to stamp relative to each other to produce the penetration. Groove 113, plus the upper and lower molds must extend from one end of the vertical pipe 11 to the other end to punch out the equidistantly arranged through grooves 113, the production is not easy, the cost is relatively high, therefore, it is not easy to meet the requirements of mass production condition
