Description

Column-type clamping structure

This invention relates to a simple locking structure that allows users to quickly adjust the height of the adjustment bracket relative to the base.

When displaying and selling goods, merchants usually arrange the goods on display racks and hang promotional or advertising banners or panels on the racks so that consumers can obtain relevant information about the goods or the merchants.

Since the positions of the racks on which promotional or advertising banners or panels are hung are fixed and cannot be adjusted, when the products displayed on the racks are changed, some products may obscure the promotional or advertising panels, making it impossible for consumers to directly see the information on the banners or panels.

To address the aforementioned issues, display racks are typically equipped with adjustable shelves, allowing merchants to hang fabric strips or panels on them. The height of the shelf relative to the base of the display rack can be finely adjusted to accommodate different products, preventing the fabric strips or panels from being obscured by the merchandise.

The adjustment frame and the base are usually connected by a locking structure. A common locking structure is to have multiple positioning holes or long holes that are spaced apart on the base or adjustment frame, and to use fasteners to pass through one of the positioning holes or long holes to lock the adjustment frame to the base.

However, when making adjustments, it is usually necessary to use tools (such as screwdrivers, wrenches, etc.) to loosen the fasteners, adjust the height of the adjustment frame, and then re-tighten the fasteners, which is not conducive to quick reconfiguration at the display site.

Therefore, the existing clip-on structure is rather cumbersome to use and does not allow merchants to quickly adjust the position of the fabric strips or panels relative to the display rack according to different products.

In view of the aforementioned shortcomings, the main objective of this invention is to provide a column-type locking structure that allows for quick adjustment of the position of the adjustment bracket relative to the base without the need for tools.

To achieve the aforementioned objectives, the column-type locking structure provided by this invention comprises: a base; an adjusting frame, the adjusting frame including a limiting member and at least one sleeve extending downward from the limiting member; and a plurality of positioning groups, the plurality of positioning groups being arranged at intervals on the base, each positioning group including at least one positioning sleeve extending upward and downward, the at least one positioning sleeve being used to sleeve the at least one sleeve of the adjusting frame and to support the limiting member, the adjusting frame being selectively inserted into one of the positioning groups, such that the sleeve is sleeved on the positioning sleeve of the positioning group, and the limiting member of the adjusting frame supporting the end face of the positioning sleeve of the positioning group.

Utilizing the aforementioned technical features, when adjusting the position of the adjustment frame relative to the base, the user only needs to lift the adjustment frame upwards and insert the connecting pin into the positioning sleeve of another positioning assembly. The limiting member can be used to support and limit the position at the end face of the positioning sleeve. The height of the adjustment frame relative to the base can be adjusted quickly and conveniently without the use of tools, and the adjustment frame and the base are stably connected.

Please refer to Figures 1, 4 and 6. A preferred embodiment of the column-type fastening structure provided by this invention includes a base 10, an adjustment frame 20 and a plurality of positioning groups 30.

Referring to Figures 2, 3, and 5, the adjustment frame 20 includes a limiting member 23 and at least one sleeve post 215 extending downward from the limiting member 23. A plurality of positioning groups 30 are arranged at intervals on the base 10, each positioning group 30 including at least one positioning sleeve 31 extending upwards and downwards. Each positioning sleeve 31 can be a cylindrical tube and is used to engage the sleeve post 215 of the adjustment frame 20 and support the limiting member 23. Therefore, the sleeve post 215 of the adjustment frame 20 can be selectively inserted into the positioning sleeve 31 of one of the positioning groups 30, and the limiting member 23 of the adjustment frame 20 can be supported on the end face of the positioning sleeve 31, thus limiting the assembly position of the adjustment frame 20 relative to the base 10.

Specifically, the adjustment bracket 20 includes a plurality of horizontally spaced socket posts 215, each socket post 215 being a round rod. The limiting member 23 extends horizontally and engages with the plurality of socket posts 215, and the limiting member 23 is positioned on the side of the socket posts 215 away from the base 10. Each positioning assembly 30 includes a plurality of horizontally spaced positioning sleeves 31, the plurality of socket posts 215 being respectively inserted into the plurality of positioning sleeves 31, and supported on the end faces of the plurality of positioning sleeves 31 by the limiting member 23.

In this preferred embodiment, the adjustment frame 20 may include a plurality of spaced uprights 21 and at least one crossbar 22 connecting the plurality of uprights 21. The limiting member 23 extends laterally and connects the plurality of uprights 21. The section of each upright 21 extending downward from the limiting member 23 forms the socket post 215. The lengths of the plurality of socket posts 215 extending downward from the limiting member 23 are different.

Preferably, referring to Figures 2, 3 and 6, the positioning sleeves 31 of each positioning group 30 are not aligned with the positioning sleeves 31 of another positioning group 30, so that there are no other positioning sleeves 31 directly above each positioning sleeve 31. When the socket post 215 of the adjusting frame 20 is inserted into the positioning sleeve 31, it is blocked and interfered with by the positioning sleeves 31 of other positioning groups 30.

Please refer to Figures 3, 7, and 8. When adjusting the position of the adjusting bracket 20 relative to the base 10, the user only needs to lift the adjusting bracket 20 upwards to completely separate the socket 215 from the positioning sleeve 31, and then insert the socket 215 into the positioning sleeve 31 of another positioning assembly 30. The limiting member 23 can be used to support the end face of the positioning sleeve 31 for limiting.

Since the connecting post 215 of the adjusting frame 20 is fitted inside the positioning sleeve 31 of each positioning group 30, it can stably support the adjusting frame 20, making the adjusting frame 20 less prone to tilting. It can also be supported and limited by the limiting member 23. Without the need for tools and fasteners, the height of the adjusting frame 20 relative to the base 10 can be quickly and conveniently adjusted, and the adjusting frame 20 and the base 10 can be stably connected.
