Description
Technical Field
The invention relates to a furniture connecting piece, in particular to a hidden connecting rod with wedging connection.
Background
The modern plate furniture is mostly assembled furniture, and is convenient to transport and assemble and disassemble, so that the modern plate furniture becomes a mainstream product in the market, but the furniture is assembled by the most commonly used two-in-one or three-in-one connecting piece, the connecting mode is simple and convenient, the application is mature, wherein the two-in-one or three-in-one connecting piece needs a connecting rod and a core-offset locking wheel, the connecting rod is divided into two types, namely an all-metal polished rod or embossing rod, the rods are straight rods with shoulder threads or step rods, the other type is a plastic-coated rod, the metal rod is coated with plastic, when the plastic-coated rod is subjected to a large force in the axial direction towards the screw head, the plastic-coated body is separated from the base body, the plastic-coated body can slide towards the screw head direction, the tops of the rod parts of the two types of products are designed as the mounting and positioning functions, and the rod parts are provided with steps, the universal connecting piece is adopted to process a pre-buried hole for installing the eccentric locking wheel on a furniture vertical plate or a laminated plate surface in advance before assembly, the hole is always exposed outside after the assembly is finished, the appearance of a product is seriously influenced, the existing solution is to conceal the hole through near-color stickers or plastic covers, the solution is easy to fall off, only a temporary coping method is needed, labor and time are wasted, the integral consistency of the appearance cannot be achieved, and the maximum appearance defect of modern plate type assembled furniture is overcome.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides the hidden connecting rod with wedging connection, so that the connecting rod can be used as a common connecting rod and can also be used as a hidden connecting rod.
In order to achieve the above object, the present invention provides the following technical solutions.
Have the hidden connecting rod of wedging connection concurrently, scheme one, all metal connecting rod, including the screw head of connecting rod, the neck, pole portion and screw thread portion, screw head, neck, pole portion and screw thread portion component as an organic whole, pole portion front end be equipped with guide bar portion, the rear end is equipped with wedging pole portion, guide bar portion and wedging pole portion component as an organic whole, wedging pole portion lean on guide bar portion end little, and lean on screw thread portion end big.
Furthermore, the wedging rod part is provided with at least two symmetrical bulges which are uniformly distributed in the radial direction.
Further, the wedging rod part can be a multi-surface cone or a special-shaped body with a small front end and a large rear end.
Have the hidden connecting rod that wedging was connected concurrently, scheme two, the connecting rod is moulded to the package, including screw head, neck, pole portion and screw thread portion, screw head, neck, pole portion and screw thread portion metal component as an organic whole, pole portion in the middle of carry out the undergauge to wrap outside the undergauge and mould, establish guide bar portion in the front end periphery of the package body, wedging pole portion is established to the rear end, front end package all guide bar portion with rear end wedging pole portion be integrative component, wedging pole portion lean on guide bar end little, and it is big to lean on screw thread end.
Furthermore, the wedging rod part is provided with at least two symmetrical bulges or ribs which are uniformly distributed in the radial direction.
Further, the wedging rod part can be a multi-surface cone or a special-shaped body with a small front end and a large rear end.
When the connecting rod is used as a hidden connecting rod for wedge connection, the front end of the guide part of the connecting rod can be conveniently inserted into the corresponding hole, so that the installation can be initially positioned, and the original conventional eccentric locking wheel pre-buried hole is not punched on the vertical plate or the laminated plate of the furniture, the invention has the advantages that the wedging connection is carried out through the wedging part, the initial positioning and the wedging connection can be realized no matter the first scheme metal rod or the second scheme plastic-coated rod is adopted, the failure caused by vibration separation of the plastic-coated body of the wedging part in the installation working process is avoided, the hiding of the eccentric lock wheel hole at the optical connection part of the furniture is realized, the universal connecting rod can be connected in a conventional mode or in a wedging mode during assembly, the universal connecting rod can be flexibly applied well, the connecting rod adopting the wedging connection can be assembled and disassembled only by reversely hitting the connecting rod adopting the wedging connection through a vertical plate or a laminated plate of the furniture, the disassembly is difficult due to the separation of the plastic-coated body of the wedging part and a base body, the disassembly mode of other common rods is the same as the original conventional mode when the common rods are used, the integral consistency of the appearance of the furniture is well realized, and the convenience is realized, the installation is firm, has obtained fine beneficial effect.
Although the appearance of the common connecting rod in the market has certain similarity with the invention, the common connecting rod does not have the wedge connecting function when in use, because the all-metal rod is a polished rod or a straight rod of an embossing rod and does not have the function of an independent wedge part, if the all-metal rod is used as the wedge part, the initial positioning function is lost when in installation, and the common plastic-coated rod cannot be assembled into furniture, the iron rod in the plastic-coated part of the common plastic-coated rod is as large as the neck part, and if the common plastic-coated rod is used as the wedge connecting, the plastic-coated body can be separated from the base iron rod coated by the common plastic-coated rod in the vibration process of assembling, beating or moving, and the like, so that the close connection and firm installation of the furniture cannot be realized.
