Description

Self-locking tensioning bolt for corrugated board and hollow board
Technical Field
The invention relates to the technical field of corrugated board tensioning devices, in particular to a self-locking tensioning bolt for corrugated boards and hollow boards.
Background
The novel corrugated paper material is used for replacing exhibition works made of traditional wood board materials, has the advantages of environmental protection, light luxury, high efficiency, low cost and the like, and can achieve the four-party win-win effect of venue parties, contractors, service providers and exhibitors. When corrugated paper is processed into artware, exhibition showcases, furniture and other products, the products need to be tensioned to prevent cracking and abnormal sound. The traditional wood furniture uses iron nails, wood glue, screws and other methods to reinforce and form the furniture and the exhibition stand. After the blank is made, the hole sites such as iron nails and screws are filled with materials such as putty powder, glue and the like on the surface, and the used surface is smooth and clean and has uniform color. Then the surface treatment is carried out by paint and coating to prepare the finished product of furniture. The corrugated paper is made of paper on two sides and corrugated filling is used in the middle. The surface is smooth, the interior is hollow, and corrugated paper all has the limitation in using above-mentioned material in the installation. Due to the weight of the product, the structure is different from that of the wood board. And under the requirements of appearance, environmental protection, beauty and the like, the existing materials can not meet the requirements from the aspect of recycling of new products.
For example, chinese patent document discloses a fixing screw [ application No.: CN201220586521.6], including: the screw rod is divided into two symmetrical halves by the through groove. When the light barrier is used, the alloy needle penetrates through the screen firstly, then the alloy needle is fixed on the light barrier by the fixing screw, and the notch of the screw is slightly larger than the alloy needle, so that the alloy needle can have a certain moving space under the condition of fixing. Such a screen is not only light and fast but also has a very small patchwork effect, in which the slotted screws play a very important role. The product has low cost, convenient transportation and ensures the safety of the connecting piece. Above-mentioned scheme, though can play fixed connection's effect, nevertheless difficult dismantlement is not fit for reuse, and installs and also not pleasing to the eye enough on level and smooth corrugated paper surface.
In view of the above disadvantages, there is a need for a corrugated cardboard tensioning bolt which can fixedly connect two or more corrugated cardboards or hollow boards, can be detached at any time and any place, is convenient and practical, and can be reused; the bolt appearance material needs to be smooth and mellow for installing and need have certain aesthetic property on glossy corrugated paper stand surface.
