The present invention relates to a railing securing joint for securing the railing onto the ground.
Current most of common railing connection structure have a block and a bolt. The block has a first through hole at one end and a second through hole at the other end of the block. The diameter of the first through hole is larger than the second through hole, and the holes are connected to each other. One end of the bolt is formed with a head, and the bolt is inserted through the second through hole, and the head of the bolt is pressed against the end of the first through hole, so that the block can be locked on the ground, and the railing is directly placed on the outer periphery of the block to form a quick connection between the floor and the handrail.
However, the above conventional structure still has the following problems in practical application: 1. The locking distance of the bolt is short, so it is less stable after installation. 2. In order to lock the bolt, a screw locking tool such as a screwdriver or hexagonal wrench is required and it must be aligned with the through holes in order to lock it smoothly. However, sometimes the installation space is too narrow and the screw locking tool cannot be fully upright and rotated, which makes it difficult to lock the block. or it cannot be locked at all, which increases the difficulty of the installation.
Therefore, it is desirable to provide a rolling storage cart with drawers to mitigate and/or obviate the aforementioned problems.
An objective of present invention is to provide a railing securing joint, which is capable of improving the above-mention problems.
In order to achieve the above mentioned objective, a railing securing joint has a stepped shape and a first member having a larger diameter and a second member having a smaller diameter. The second member has a plurality of flexible claws, and each pair of the flexible claws has a dividing gap in between and a plurality of longitudinal ridges, such that each of the dividing gaps has a recess. One end of the first member facing the second member further has an internal flange, the flange is smaller than the second member to define a compression space between the second member and the flange. The flange further has a through hole passing through the first member for accepting a bolt for locking. An edge is formed between the first member and the second member.
Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
First, please refer to
In addition, one end of the first member 11 away from the second member 12 further comprises a sloped surface 113 such that the securing joint can be employed at a slope location.
Also, each flexible claw 121 has a curved shape.
Moreover, one end of each flexible claw 121 away from the first member 11 has a beveled angle 125, When the railing 30 is sleeved onto the securing joint 10, the beveled angle 125 can be used to guide and push each flexible claws 121 to be slightly compressed, so that the second member 12 can be more easily inserted into the railing 30. After the set is completed, the flexible claws 121 slightly rebound back and fully press against the inner wall of the railing 30, thereby greatly improving the engaging strength between the securing joint 10 and the railing 30.
Additionally, each securing joint 10 comprises four dividing gaps 122 in a cross-shaped arrangement.
In actual use, the bolt 20 is put into the through hole 112 from the second member 12, so that the securing joint 10 can be fixed on the ground by using the locking knot of the bolt 20. When the bolt 20 is locked, the recess 124 can also be used to provide space for screwdrivers or hex wrenches and other screw-locking tools 40, so that the screw-locking tools 40 can lean to one side without being in the same straight line as the through hole 112 and still drive the bolt 20 smoothly. Please refer to
The above-mentioned railing securing joint has the following advantages: 1. The securing joint 10 is provided with the flange 111, so that the locking area of the bolt 20 is expanded as the flange 111 to increase the installation og the securing joint, it will be relatively stable. 2. When the bolt 20 is locked, the recess 124 can be used to provide a screwdriver or a hex wrench and other screw-locking tools 40 for installation, so that the screw-locking tools 40 can lean in another direction than the through hole 112, but can still drive the bolt to lock smoothly. In this way, the installation difficulty of the securing joint 10 can be significantly reduced, and it is more suitable for use in narrow spaces. Moreover, the longitudinal ridges 123 reinforce the flexible claw 121, and the compress space 13 makes it easier for the flexible claw 121 to compress inward and then further stretch outward.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
