Description

Technical Field

[0001] The utility model relates to the technical field of composite floors, in particular to a wear-resistant and flame-retardant multi-layer composite floor. Background Art

[0002] Composite wood flooring, also known as "laminate wood flooring", is wear-resistant and suitable for places with concentrated traffic. The existing composite multi-layer environmentally friendly flame-retardant and wear-resistant flooring is cumbersome to lay, which increases the workload of workers in laying the floor.

[0003] The patent with application number 202123361234.3 discloses a composite multi-layer environmentally friendly flame-retardant and wear-resistant floor, including a floor main body, a fixing groove is provided on one side of the floor main body, a protrusion is provided on the other side, and also includes a stabilizing mechanism, and the stabilizing mechanism includes a card slot, a receiving slot, a movable block, a fixing ring one, a spring and a fixing ring two, and a symmetrically distributed card slot is provided on the outer side of the protrusion; the beneficial effect of the utility model is: through the designed stabilizing mechanism, the two floor main bodies can be quickly spliced ​​together, reducing the workload of workers in laying the floor.

[0004] The above technical solution inserts the protrusion into the fixing groove and keeps the protrusion fixed by the fastener elastically arranged in the fixing groove. Since the protruding protrusion will block the composite floor moving downward, it is necessary to move the two composite floors to the same horizontal position with a certain gap during the laying process, and slide horizontally to insert the protrusion into the fixing groove. However, for the composite floor laid to the edge of the wall, the composite floor has no space for horizontal movement due to the obstruction of the wall, so the composite floor at the edge cannot be laid due to the obstruction of the protrusion. Utility Model Content

[0005] The purpose of the utility model is to provide a wear-resistant and flame-retardant multi-layer composite floor in view of the shortcomings of the prior art. The function of moving and installing the composite floor body is achieved by cooperating with the slot structure on the composite floor body through the elastically arranged clamping part structure, thereby solving the problem that the composite floor at the edge cannot be laid due to the obstruction of the protrusions.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant and flame-retardant multi-layer composite floor, which includes a composite floor main body connected end to end and a card slot opened on the side wall of the composite floor main body, the composite floor main body is provided with a telescopic groove at one end away from the card slot, a card connecting part is elastically inserted in the telescopic groove, one end of the card connecting part extending out of the telescopic groove is fitted in the card slot, and a plurality of grooves are provided at the other end of the card connecting part, wherein a plurality of accommodating holes are provided on the inner wall of the card connecting part, and a spring that abuts against the inner wall of the telescopic groove is embedded in the accommodating hole.

[0007] When the wear-resistant and flame-retardant multi-layer composite floor of the present technical solution is used, a card slot is provided at one end of the composite floor body, and a telescopic slot is provided at the other end of the composite floor body, and a spring in the telescopic slot pushes the card slot to protrude from the side wall of the composite floor body. When the composite floor body is installed, the arc portion abuts against the side wall of the composite floor body, thereby squeezing the card slot to shrink into the telescopic slot. When the two composite floor bodies are connected end to end, the spring in the telescopic slot pushes the card slot to be inserted into the card slot, thereby keeping the two composite floor bodies fixed, facilitating the shrinkage of the protruding card slot, and avoiding the card slot blocking the composite floor body and making it impossible to install. A plurality of grooves are provided on the card slot, and support blocks are provided in the grooves. The support blocks support the telescopic slot, thereby avoiding the situation where the strength of the composite floor body is weakened due to the telescopic slot on the composite floor body, and the nano flame retardant coating can prevent the composite floor body from burning, and the melamine resin wear-resistant coating increases the wear resistance of the top of the composite floor body.

[0008] Preferably, a plurality of leveling grooves are provided at the bottom end of the composite floor main body, and beautifying grooves are provided at both sides of the top end surface of the composite floor main body.

[0009] Furthermore, a nano flame retardant coating is provided on the top of the composite floor main body, and a melamine resin wear-resistant coating is sprayed on the top of the nano flame retardant coating.

[0010] Furthermore, a support block is embedded in the groove, and both ends of the support block are fixedly connected to the inner wall of the telescopic slot.

[0011] Furthermore, one end of the clamping portion extending out of the telescopic slot is symmetrically provided with an arc portion, and the arc portion abuts against the top end of the composite floor body.

[0012] Furthermore, positioning rods are fixed equidistantly on the inner wall of the telescopic slot, and one end of the spring extending out of the accommodating hole is sleeved on the positioning rod.

[0013] The beneficial effects of the utility model are:

[0014] (1) The utility model provides a card slot at one end of the composite floor body and a telescopic slot at the other end of the composite floor body. The spring in the telescopic slot pushes the card slot to protrude from the side wall of the composite floor body. When the composite floor body is installed, the arc-shaped portion abuts against the side wall of the composite floor body, thereby squeezing the card slot to shrink into the telescopic slot. When the two composite floor bodies are connected end to end, the spring in the telescopic slot pushes the card slot to be inserted into the card slot, thereby keeping the two composite floor bodies fixed, facilitating the contraction of the protruding card slot, and avoiding the card slot blocking the composite floor body and making it impossible to install it.

[0015] (2) The utility model has a plurality of grooves on the clamping part, and support blocks are arranged in the grooves. The support blocks support the expansion grooves, thereby avoiding the situation where the strength of the composite floor is weakened due to the expansion grooves on the composite floor body. The nano flame retardant coating can prevent the composite floor body from burning, and the melamine resin wear-resistant coating increases the wear resistance of the top of the composite floor body.
