Description

Technical Field

[0001] The invention relates to the technical field of assembled floor installation, and in particular to a fastener structure for assembled floor installation. Background Art

[0002] Flooring is the surface layer of the ground or floor of a house. It is made of wood or other materials. There are many types of flooring. According to the structure, there are: solid wood flooring, laminate flooring, three-layer solid wood composite flooring, bamboo flooring, anti-corrosion flooring, cork flooring and the most popular multi-layer solid wood composite flooring; according to the use, there are: home use, commercial use, anti-static flooring, outdoor flooring, stage dance flooring, sports hall flooring, track and field flooring, etc.; according to the environmental protection level, there are: E0 flooring, E1 flooring, F4 flooring, JAS star standard F4 star flooring, etc.

[0003] The floors seen on the market today, such as solid wood floors, generally have wooden grooves and wooden tenons around them. When laying the floor, first the ground is paved with cement sand, then the keel is set up on the ground, the plywood is fixed, and then the floor is fixed with nails. This installation method has many defects: first, it is difficult to install, repair and disassemble, and it is very easy to damage the floor; second, the amount of wooden auxiliary materials (such as keels, plywood, etc.) used in the installation is large and the cost is high; third, before installation, the ground must be leveled with cement, sand and gravel, which increases the load on the building; fourth, it cannot solve the problem of cracks and arches caused by the shrinkage and swelling of wood due to changes in environmental humidity.

[0004] In order to solve the above defects, third-party fasteners are increasingly being used in wooden floor paving. For example, the Chinese utility model patent with announcement number CN2630371Y discloses a wooden floor fixing fastener, whose cross-sectional shape includes a clamping end that matches the tongue and groove of the floor and a fixed end connected to the clamping end, the bottom of the fixed end is flush with the bottom of the wooden floor, and there is a fixing hole on the fixed end. The fastener also has the following problems: 1. When the use environment of the wooden floor changes, the wooden floor is prone to shrinkage and swelling, and the floor paving method using the fastener cannot adjust the shrinkage and swelling of the wooden floor. Once the use environment changes, it is easy to cause cracks and arches in the floor; and the wooden floor shrinks due to changes in moisture content, resulting in large gaps between wooden floors, which are prone to accumulation of dust and flies, reducing the user's living quality. 2. The wooden floor paving method using the fastener cannot limit the lateral movement of the floor. The wooden floor is prone to lateral movement, and it is also easy to cause gaps between wooden floors. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a fastener structure for installing an assembled floor.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A fastener structure for installing an assembled floor, comprising a body and a mounting plate arranged at the bottom end of the body, the body comprising a bottom plate, side walls arranged at both ends of the bottom plate, a column arranged in the middle of the bottom plate and protrusions movably arranged on both sides of the column, the column is a hollow structure, one end of the protrusion located in the column is provided with a first inclined surface, both sides of the protrusion are provided with a fixing plate, a spring is arranged in the column, one end of the spring is connected to the fixing plate, and the other end of the spring is connected to the inner wall of the column, the bottom end of the column is provided with an opening, a mounting column is movably arranged in the opening along the axial direction of the column, the top end of the mounting column is provided with a second inclined surface, when the mounting column moves upward, the second inclined surface abuts against the first inclined surface, so that the protrusion moves toward the outside of the column, the bottom end of the mounting plate is provided with a groove, an adjustment plate is rotatably connected in the groove, and the bottom end of the bottom plate is provided with a fixing groove, and the adjustment plate can be clamped and fixed in the fixing groove. During installation, the adjustment plate is clamped and fixed in the fixing groove, the top end of the adjustment plate abuts against the bottom end of the column, and after the first inclined surface abuts against the second inclined surface, the outer part of the protruding box column moves, and the spring is compressed to generate elastic force. When disassembly is required, the knob is turned in the opposite direction, and the knob can drive the adjustment plate to rotate through the rotating rod. After the adjustment plate is separated from the fixing groove, the installation column moves downward under the elastic force of the spring, and the protrusion is retracted into the column, separating the body from the wooden floor.

[0008] Preferably, a mounting groove is provided at the bottom end of the base plate along the length direction of the main body, and the mounting plate is arranged in the mounting groove.

[0009] Preferably, a rotating rod is rotatably connected to the mounting plate, the adjustment plate is fixed to one end of the rotating rod, one end of the rotating rod passes through the adjustment plate and is connected to the rotating plate, and a knob is provided on the rotating plate.

[0010] Preferably, a rotation groove is provided at one end of the knob away from the rotation rod.

[0011] Preferably, a female groove wooden floor and a male tenon wooden floor are provided at the top of the main body, and the column and the protrusion extend into the female groove wooden floor and the male tenon wooden floor to form a fastener structure.

[0012] Preferably, a movable hole is provided on the top side wall of the column, and the protrusion is movably arranged in the movable hole. There are multiple movable holes, and the multiple movable holes are evenly arranged along the length direction of the body.

[0013] Preferably, the cross-sectional shape of the fixing groove is circular, the adjustment plate is in the shape of an elongated strip, and the length of the adjustment plate is smaller than the diameter of the cross-sectional circular shape of the fixing groove.

[0014] Preferably, a buffer pad is provided at the bottom end of the body.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention rotates the adjustment plate so that the adjustment plate can be clamped and fixed in the fixing groove, and the top end of the adjustment plate abuts against the bottom end of the mounting column, so that the first inclined surface on the mounting column abuts against the second inclined surface at one end of the protrusion, thereby causing the protrusion to move toward the outside of the column. At the same time, the spring is compressed to generate elastic force, and the column, the protrusion protruding outward, and the side wall form a fixing fastener with the wooden floor, which can prevent the wooden floor from moving longitudinally.

[0017] 2. In the initial state of the present invention, the protrusion is located inside the column. When the column is matched with the wooden floor, the mounting plate is installed so that the mounting column moves inside the column and abuts against the end of the protrusion. After the protrusion is further clamped and fixed with the wooden floor to form a stable fixing fastener, the adjustment plate is rotated and clamped and fixed in the fixing groove, so that the mounting column always abuts against the protrusion, forming a stable structure, and the installation is more convenient and efficient.

[0018] 3. The column of the present invention has a hollow structure, which makes the column more elastic as a whole. When the wooden floor shrinks or swells, the lateral spacing of the wooden floor can be effectively adjusted to achieve gap compensation between wooden floors. This not only solves the problems of cracks and arching that have always plagued solid wooden floors, but also avoids the generation of large gaps between wooden floors, which leads to the accumulation of dust and flies, thereby improving the living quality of users.
