Description

Positioning connector for wood trim for upholstery

The invention relates to a positioning connector for a wooden profile for interior decoration, in particular to a technical field of interior decoration, and relates to a connector for interior decoration, in particular to a positioning connector for a wooden profile for interior decoration. .

With the progress and development of society, people are increasingly demanding interior decoration. From the aspects of the comfort of the living and the plasticity of the materials, it is often the first time that the wooden decoration materials are used for the interior decoration.

In the decoration industry, pneumatic nails of different types and sizes with magnetic properties - fixed joints as decorative materials have been widely used. Using pneumatic nails and other tools to instantly nail the gas nails, it can realize wood including solid wood flooring, siding, door and window covers, skirting boards, and wooden lines (including the Yinxian, Yangxian, waistline, top edge, and door and window frame edges). Quick connection between profiles and walls or concrete floors or wooden keels. Its outstanding advantages are: it helps to shorten the construction period of the decoration; thereby reducing the time cost of the decoration.

However, practice shows that there are many defects in the use of such connectors and connection methods, including: 1. After the pneumatic nails as the connecting members are nailed, each gas nail is completely exposed to the decorative profiles. The outer surface, and the local depression around each gas nail, directly affecting The overall decoration effect; therefore, it is only suitable for far-sightedness, it is not suitable for close-up; 2. Once the gas nail is damp, it will produce rust. Over time, the joint between the joint and the profile will be loose, and finally it will be separated from the profile; Once the nail is nailed in, if there is a design change or if the construction is found to be in need of rework, it can only be destructively removed. In this way, not only will expensive wood resources be wasted, but also the cost of materials filled by users and the time cost of rework will be increased. 4. For the installation structure of the skirting board, the female or male feet in the indoor wall In other parts, it is generally used to cover the end face of the skirting board assembled on two mutually perpendicular walls by using a single corner component; in actual use, whether people walk or drag normally indoors When sweeping the floor, it is often inadvertently knocked out, which is very troublesome. In addition, for the installation of solid wood flooring, although the current solid wood flooring is processed and produced, both sides of the length of the wooden floor and both ends in the width direction are There is a matching "male and female 榫" structure, but it turns out that although this "male and female 榫" structure can realize the overall assembly of the wooden floor, it still cannot guarantee the use of the wooden floor after a period of use. It is not affected by external forces or is affected by moisture or cold expansion and contraction.

To this end, the industry has added an installation program: first drill a nail on the male weir on the side of the length of the wooden floor, and then nail the nail into the nail on the floor of the wooden keel. In order to prevent the floor from being turned over during the future use.

However, as we all know, in the overall budget of interior decoration, especially home decoration, the proportion of the cost of solid wood flooring is often large, when the user needs to maintain the previous maintenance When a good wooden floor is moved into a new home as a whole, it is almost impossible to remove the floor nail one by one without causing damage to the wooden floor. For this reason, people are eagerly expecting a connector to be introduced as soon as possible. Depending on the function of the connector, the quick positioning and installation of the above-mentioned wooden profile including solid wood flooring can be realized; if necessary, it can be connected with the connector. Dismantled together intact, realizing the installation and re-use of wooden profiles such as wooden floors and siding, and reusing them, thereby greatly reducing the consumption of expensive wood resources; at the same time, it is expected that such connectors can be completely concealed in the above-mentioned indoors. The back of the profile used for the decoration greatly enhances the overall quality of the interior decoration, which should be the best solution.
