Definitions
- the present invention relates to the technical field of flooring, and particularly to a floor board of rapid side-slide installation.
- Solid wood floor board refers to the decorative floor board produced after the drying and machining of the wood, which is characterized by its natural patterns, comfortable foot feelings, and application safety. Hence, the solid wood board is commonly used in the floor decoration of a bedroom, living room, study room, and the like as a high-grade material.
- the traditional solid wood flooring has high requirements on the environment and conditions of use, because it tends to expand and deform after being affected with damp or absorbing water, and it tends to contract, deform, and even fracture after removing the water by heating. As a result, the floor boards would become damaged, so the application of the traditional solid wood floor boards is limited.
- a high-temperature heat treatment for carbonization or a secondary moisture balance is usually applied to the solid wood blank. Then, the tongue and the groove of the wood board are sprayed with the edge sealing paint, the bottom surface is sprayed with the paint, and the tongue, the groove, and the bottom surface are subjected to a film-coating process. Alternatively, after the bottom surface is sprayed with the paint, and the tongue and the groove of the wood board are sealed with the wax, the bottom surface is subjected to the film-coating process to block the access of wood surface to water or moist air.
- the adverse effects of environmental temperature and humidity changes on the wood can be reduced to achieve the moisture-proof and moisturizing effects.
- the above flooring still have the following drawbacks.
- the heat treatment can change many natural properties of the wood, such as weakened physical properties, and darker wood color, etc.
- the secondary moisture balance treatment although can protect the natural properties of the wood, it still has the following drawbacks.
- the paint coated on the tongue and the groove cannot completely cover the surface of the wood, so it only provides partial protection on moisture-proof and moisturizing.
- the tongue and the groove are sealed with the wax, after the wax is applied, the wax film tends to get damaged and falls off due to the crashing during the movement and installation when the tongues and grooves of different boards are being put together, so the function of the wax is affected.
- the plastic material tends to overflow to the surface of the board body, and the plastic frame around the floor board is quite outstanding after direct flooring, which affects the appearance of the floor board; hence, a secondary treatment is required to remove the redundant plastic material on the surface of the board body after the injection molding.
- a secondary treatment is required to remove the redundant plastic material on the surface of the board body after the injection molding.
- a floor board of rapid side-slide installation includes a board body and a plastic frame covering around the board body.
- a plurality of sets of limiting connectors are provided on the plastic frame.
- Two adjacent board bodies are fixed by an engagement of corresponding limiting connectors on the plastic frames around the board bodies.
- a first groove is provided on a periphery of the board body near an upper surface of the board body, and a protruding boss having an inclined side surface is formed between a top surface of the first groove and the upper surface of the board body.
- An angle between the inclined side surface and the top surface of the first groove is an acute angle.
- the plastic frame is provided under the protruding boss and is embedded in the first groove, and an outer side wall of the plastic frame and a protruding edge of the protruding boss are on the same vertical plane.
- the protruding boss on the periphery of the board body is fitted with an inner wall of a mold. Since the protruding boss has the inclined side surface, the protruding edge of the inclined side surface of the protruding boss and a side wall of the mold make an injection molding space isolated with the upper surface of the board body to prevent a plastic material from overflowing to the upper surface of the board body.
- the plastic frame is formed on the periphery of the board body, and the plastic frame is partially embedded in the first groove to enhance a firmness of the board body and the plastic frame.
- the plastic frame is provided under the protruding boss and an outer side wall of the plastic frame and the protruding edge of the protruding boss are on the same vertical plane. Therefore, after the injection molding of the board body, the plastic frame is hidden under the board body, and the plastic frame is invisible by vertically viewing from the upper surface of the board body, so the appearance of the flooring will not be affected after installation. No redundant plastic material is left on the upper surface of the board body, so no secondary treatment is required.
- the angle between the inclined side surface and the top surface of the first groove ranges from 80° to 89°.
- an area of the upper surface of the board body is larger than an area of a bottom surface of the board body, the periphery of the board body is between the upper surface and the bottom surface, the periphery of the board body is configured with a stepped shape, a second groove is provided on the periphery of the board body near the bottom surface of the board body, and the plastic frame is embedded in the second groove.
- the step shape is configured to set aside space for a formation of the limiting connectors for the slide installation, and a sliding rail surface for assembling the limiting connectors can be formed on the step.
- the second groove is configured to make the plastic frame partially embedded in the second groove during the injection molding, thereby further enhancing the firmness of the board body and the plastic frame.
- the plastic frame includes a bottom frame and a side frame provided inside the bottom frame and integrally formed with the bottom frame.
- Each set of the limiting connectors includes a first engaging member and a second engaging member which are adjacent to each other.
- the first engaging member protrudes outward from a side wall of the side frame, and the first engaging member is connected to a bottom surface of the bottom frame.
- the second engaging member protrudes downward from the bottom surface of the bottom frame, and the first engaging member and the second engaging member on two sides of the side frame are arranged in a staggered manner, wherein, a distance between the first engaging member in one set of limiting connectors and the second engaging member in the adjacent set of limiting connectors is greater than a length of the first engaging member.
- the first engaging member and the second engaging member of the two adjacent floor boards are matched and engaged with each other.
- the same engaging members, i.e. the first engaging members or the second engaging members, of the two adjacent floor boards are staggered, and the mating engaging members of the two adjacent floor boards are aligned and matched to each other.
- one of the two floor boards is side slid to make them assembled together through a limiting function of the first engaging member and the second engaging member, and a displacement is avoided.
- the installation process is quite simple, and floor boards are reusable. Moreover, it is unnecessary to distinguish the left and right of the limiting connectors of the floor boards, so the installation efficiency can be further improved and the installation difficulty can be reduced.
- an upper surface of a protruding portion of the first engaging member is provided with a first engaging portion that protrudes upward.
- a first limiting groove is formed between the first engaging portion and a side wall of the bottom frame.
- a second limiting groove is formed between the second engaging member and a side wall of the side frame.
- a width of the first limiting groove is greater than or equal to a width of the second engaging member, and a width of the second limiting groove is greater than or equal to a width of the first engaging portion.
- the width of the first limiting groove is equal to the width of the second engaging member, and the width of the second limiting groove is equal to the width of the first engaging portion, so as to improve the stability.
- the first engaging portion is a strip block having a semicircular or square cross-section, and chamfers are provided at both ends of the strip block. The two ends of the first engaging portion are provided with the chamfers to facilitate the engagement during assembling.
- the second engaging member is a strip block having a semicircular or square part, and chamfers are provided at both ends of the strip block. The two ends of the second engaging member are provided with the chamfers to facilitate the engagement of during assembling.
- a length of the first engaging portion is equal to a length of the second limiting groove.
- a length of the second engaging member is equal to a length of the first limiting groove.
- a length of the first engaging portion is equal to a length of the second engaging member, and a height of the first engaging portion is equal to a height of the second engaging member.
- the board body is composed of a front board provided on the upper surface of the board body and a back board connected to the front board and provided on the bottom surface of the board body.
- the first groove is provided at a periphery of the front board
- the second groove is provided at a periphery of the back board
- the bottom frame is provided at a back surface of the front board.
- the back board is provided in a receiving cavity surrounded by the side frame.
- an outer edge of the bottom frame is aligned with an outer edge of the front board.
- the back board is composed of a plurality of board cores, and a spacing between adjacent board cores ranges from 0.5 mm to 1.5 mm.
- the bottom surface of the board body is provided with a waterproof film, a cross-section of the waterproof film is U-shaped, and an outer edge of the waterproof film is located between the bottom frame and the board body.
- an end of the outer edge of the waterproof film is connected in the second groove in an overlapping manner.
- the waterproof film has a thickness ranging from 0.08 mm to 0.12 mm.
- a first paint layer is further provided between the waterproof film and the board body, and the first paint layer has a thickness ranging from 0.05 mm to 0.25 mm.
- the bottom surface of the board body is provided with a second paint layer, and the second paint layer has a thickness ranging from 0.05 mm to 0.25 mm.
- the upper surface of the board body is provided with a third paint layer.
- the present invention has the following advantages.
- the protruding boss on the periphery of the board body is fitted with the inner wall of the mold.
- the protruding edge of the inclined side surface of the protruding boss and the side wall of the mold make an injection molding space isolated with the upper surface of the board body to prevent the plastic material from overflowing to the upper surface of the board body.
- No redundant plastic material is left on the upper surface of the board body and no secondary treatment is required. Therefore, the cost for the secondary treatment of the redundant plastic material is saved and the production efficiency is improved.
- the plastic frame is formed on the periphery of the board body of the floor board, and the plastic frame is partially embedded in the first groove to enhance the firmness of the board body and the plastic frame. Meanwhile, the plastic frame is provided under the protruding boss and the outer side wall of the plastic frame and the protruding edge of the protruding boss are on the same vertical plane. Therefore, after the injection molding of the board body, the plastic frame is hidden under the board body, and the plastic frame is invisible by vertically viewing from an upper surface of the board body, so the appearance of the floor board will not be affected after installation.
- the angle between the inclined side surface and the top surface of the first groove is an acute angle. Since the solid wood blank is exposed to the natural environment during the processing, due to the influence of temperature and humidity, wet makes the wood itself expand and dry makes it contract, so deformation occurs.. However, since the density of a piece of wood varies at different parts, the deformation is also irregular, so the side wall of the protruding boss of the board body fitted with the plastic frame is unsmooth, which will lead to material leakage. In order to ensure that there is no gap between the side wall of the protruding boss of the board body at the wood-plastic fitting surface and the mold, the wood is machined to a certain extent to provide an inclination angle.
- the inclination angle is greater than 90 degrees, the expected effect will not be achieved. If a sharp inclination is provided, an unexpected gap will be left between the two floor boards in assembling, thereby affecting the appearance of floor board.
- the range of the inclination angle provided by the comparison tests is 80° to 89°. Moreover, the experiments leaded by the inventor found that similar technical effects can be obtained for other base materials with such an arrangement.
- the first engaging member and the second engaging member of the two adjacent floor boards are matched and engaged with each other.
- the same engaging members, i.e. the first engaging members or the second engaging members, of the two adjacent floor boards are staggered, and the mating engaging members of the two adjacent floor boards are aligned and matched to each other.
- one of the two floor boards is side slid to make them assembled together through a limiting function of the first engaging member and the second engaging member, and a displacement is avoided.
- the installation process is quite simple, and floor boards are reusable. Moreover, it is unnecessary to distinguish the left and right of the limiting connectors of the floor boards, so the installation efficiency can be further improved and the installation difficulty can be reduced.

Abstract
Description
- This application is a continuation application of U.S. patent application Ser. No. 16/398,302, filed on Apr. 30, 2019, the entire contents of which are incorporated herein by reference.
- The present invention relates to the technical field of flooring, and particularly to a floor board of rapid side-slide installation.
- Solid wood floor board refers to the decorative floor board produced after the drying and machining of the wood, which is characterized by its natural patterns, comfortable foot feelings, and application safety. Hence, the solid wood board is commonly used in the floor decoration of a bedroom, living room, study room, and the like as a high-grade material. However, due to the natural characteristics that wet makes the wood expand and dry makes it contract, the traditional solid wood flooring has high requirements on the environment and conditions of use, because it tends to expand and deform after being affected with damp or absorbing water, and it tends to contract, deform, and even fracture after removing the water by heating. As a result, the floor boards would become damaged, so the application of the traditional solid wood floor boards is limited.
- In order to gain a competitive edge in the market and meet the high requirements of the floor heat resistance for the flooring as the living standards of the consumers are upgraded, a high-temperature heat treatment for carbonization or a secondary moisture balance is usually applied to the solid wood blank. Then, the tongue and the groove of the wood board are sprayed with the edge sealing paint, the bottom surface is sprayed with the paint, and the tongue, the groove, and the bottom surface are subjected to a film-coating process. Alternatively, after the bottom surface is sprayed with the paint, and the tongue and the groove of the wood board are sealed with the wax, the bottom surface is subjected to the film-coating process to block the access of wood surface to water or moist air. Alternatively, the adverse effects of environmental temperature and humidity changes on the wood can be reduced to achieve the moisture-proof and moisturizing effects. However, the above flooring still have the following drawbacks. The heat treatment can change many natural properties of the wood, such as weakened physical properties, and darker wood color, etc. The secondary moisture balance treatment, although can protect the natural properties of the wood, it still has the following drawbacks. First, the paint coated on the tongue and the groove cannot completely cover the surface of the wood, so it only provides partial protection on moisture-proof and moisturizing. Second, the tongue and the groove are sealed with the wax, after the wax is applied, the wax film tends to get damaged and falls off due to the crashing during the movement and installation when the tongues and grooves of different boards are being put together, so the function of the wax is affected.
- There is a solid wood plastic flooring which can obtain a good moisture-proof effect by providing a plastic edge-sealing frame on the side surface of the board body. However, in the injection molding of the plastic edge-sealing frame of the above solid wood plastic flooring, the plastic material tends to overflow to the surface of the board body, and the plastic frame around the floor board is quite outstanding after direct flooring, which affects the appearance of the flooring. Hence, a secondary treatment is required to remove the redundant plastic material on the surface of the board body after the injection molding. Thus, besides the increase of the production cost of the floor board, it is easy to damage the plastic edge-sealing frame during the secondary treatment which has complicated processes and is difficult. Meanwhile, the existing solid wood plastic floor boards are inconvenient and difficult to install.
- In order to solve the following problems, in the injection molding of the plastic edge-sealing frame of the existing solid wood plastic floor board or the plastic floor board of other base material, the plastic material tends to overflow to the surface of the board body, and the plastic frame around the floor board is quite outstanding after direct flooring, which affects the appearance of the floor board; hence, a secondary treatment is required to remove the redundant plastic material on the surface of the board body after the injection molding. Thus, besides the increase of the production cost of the floor board, it is easy to damage the plastic edge-sealing frame during the secondary treatment which has complicated processes and is difficult. Therefore, the present invention overcomes the above problems by providing a floor board of rapid side-slide installation.
- In order to achieve the above objective, the following technical solutions are used in the present invention.
- A floor board of rapid side-slide installation includes a board body and a plastic frame covering around the board body. A plurality of sets of limiting connectors are provided on the plastic frame. Two adjacent board bodies are fixed by an engagement of corresponding limiting connectors on the plastic frames around the board bodies. A first groove is provided on a periphery of the board body near an upper surface of the board body, and a protruding boss having an inclined side surface is formed between a top surface of the first groove and the upper surface of the board body. An angle between the inclined side surface and the top surface of the first groove is an acute angle. The plastic frame is provided under the protruding boss and is embedded in the first groove, and an outer side wall of the plastic frame and a protruding edge of the protruding boss are on the same vertical plane.
- In an injection molding of the floor board of the present invention, the protruding boss on the periphery of the board body is fitted with an inner wall of a mold. Since the protruding boss has the inclined side surface, the protruding edge of the inclined side surface of the protruding boss and a side wall of the mold make an injection molding space isolated with the upper surface of the board body to prevent a plastic material from overflowing to the upper surface of the board body. After the injection molding, the plastic frame is formed on the periphery of the board body, and the plastic frame is partially embedded in the first groove to enhance a firmness of the board body and the plastic frame. Meanwhile, the plastic frame is provided under the protruding boss and an outer side wall of the plastic frame and the protruding edge of the protruding boss are on the same vertical plane. Therefore, after the injection molding of the board body, the plastic frame is hidden under the board body, and the plastic frame is invisible by vertically viewing from the upper surface of the board body, so the appearance of the flooring will not be affected after installation. No redundant plastic material is left on the upper surface of the board body, so no secondary treatment is required.

The step shape is configured to set aside space for a formation of the limiting connectors for the slide installation, and a sliding rail surface for assembling the limiting connectors can be formed on the step. The second groove is configured to make the plastic frame partially embedded in the second groove during the injection molding, thereby further enhancing the firmness of the board body and the plastic frame.
- As a further improvement, the plastic frame includes a bottom frame and a side frame provided inside the bottom frame and integrally formed with the bottom frame. Each set of the limiting connectors includes a first engaging member and a second engaging member which are adjacent to each other.

The second engaging member protrudes downward from the bottom surface of the bottom frame, and the first engaging member and the second engaging member on two sides of the side frame are arranged in a staggered manner, wherein, a distance between the first engaging member in one set of limiting connectors and the second engaging member in the adjacent set of limiting connectors is greater than a length of the first engaging member. By configuring the first engaging member and the second engaging member on the two sides of the side frame in the staggered manner, the first engaging member and the second engaging member of the two adjacent floor boards are matched and engaged with each other. During the installation, the same engaging members, i.e. the first engaging members or the second engaging members, of the two adjacent floor boards are staggered, and the mating engaging members of the two adjacent floor boards are aligned and matched to each other. Then, one of the two floor boards is side slid to make them assembled together through a limiting function of the first engaging member and the second engaging member, and a displacement is avoided. The installation process is quite simple, and floor boards are reusable. Moreover, it is unnecessary to distinguish the left and right of the limiting connectors of the floor boards, so the installation efficiency can be further improved and the installation difficulty can be reduced.

During assembling, the first engaging portion slides into the second limiting groove of a floor board to be assembled with the floor board of the first engaging portion, and the second engaging member slides into the first limiting groove of the floor board to be assembled for matching and positioning. During installation, the first engaging portion of the floor board is engaged with the second limiting groove of the floor board to be assembled.

- As a further improvement, the bottom surface of the board body is provided with a second paint layer, and the second paint layer has a thickness ranging from 0.05 mm to 0.25 mm.
- As a further improvement, the upper surface of the board body is provided with a third paint layer.
- Compared to the prior art, the present invention has the following advantages.
- 1. In the injection molding of the floor board of the present invention, the protruding boss on the periphery of the board body is fitted with the inner wall of the mold. The protruding edge of the inclined side surface of the protruding boss and the side wall of the mold make an injection molding space isolated with the upper surface of the board body to prevent the plastic material from overflowing to the upper surface of the board body. No redundant plastic material is left on the upper surface of the board body and no secondary treatment is required. Therefore, the cost for the secondary treatment of the redundant plastic material is saved and the production efficiency is improved.
- 2. After the injection molding, the plastic frame is formed on the periphery of the board body of the floor board, and the plastic frame is partially embedded in the first groove to enhance the firmness of the board body and the plastic frame. Meanwhile, the plastic frame is provided under the protruding boss and the outer side wall of the plastic frame and the protruding edge of the protruding boss are on the same vertical plane. Therefore, after the injection molding of the board body, the plastic frame is hidden under the board body, and the plastic frame is invisible by vertically viewing from an upper surface of the board body, so the appearance of the floor board will not be affected after installation.
- 3. The angle between the inclined side surface and the top surface of the first groove is an acute angle. Since the solid wood blank is exposed to the natural environment during the processing, due to the influence of temperature and humidity, wet makes the wood itself expand and dry makes it contract, so deformation occurs.. However, since the density of a piece of wood varies at different parts, the deformation is also irregular, so the side wall of the protruding boss of the board body fitted with the plastic frame is unsmooth, which will lead to material leakage. In order to ensure that there is no gap between the side wall of the protruding boss of the board body at the wood-plastic fitting surface and the mold, the wood is machined to a certain extent to provide an inclination angle. If the inclination angle is greater than 90 degrees, the expected effect will not be achieved. If a sharp inclination is provided, an unexpected gap will be left between the two floor boards in assembling, thereby affecting the appearance of floor board. The range of the inclination angle provided by the comparison tests is 80° to 89°. Moreover, the experiments leaded by the inventor found that similar technical effects can be obtained for other base materials with such an arrangement.
- 4. By configuring the first engaging member and the second engaging member on the two sides of the side frame in the staggered manner, the first engaging member and the second engaging member of the two adjacent floor boards are matched and engaged with each other. During the installation, the same engaging members, i.e. the first engaging members or the second engaging members, of the two adjacent floor boards are staggered, and the mating engaging members of the two adjacent floor boards are aligned and matched to each other. Then, one of the two floor boards is side slid to make them assembled together through a limiting function of the first engaging member and the second engaging member, and a displacement is avoided. The installation process is quite simple, and floor boards are reusable. Moreover, it is unnecessary to distinguish the left and right of the limiting connectors of the floor boards, so the installation efficiency can be further improved and the installation difficulty can be reduced.

- The present invention is further described with reference to the embodiments. The described embodiments are merely a part of embodiments of the present invention, rather than all. Based on the embodiments of the present invention, other embodiments achieved by those of ordinary skill in the art without creative efforts should be considered as falling within the scope of the present invention.
- As shown in
FIG. 1 andFIG. 2 , a floor board of rapid side-slide installation includes theboard body 1 and theplastic frame 2 covering around theperiphery 13 of the board body. In the present embodiment, theboard body 1 may be any one of a shaving board, a solid wood board, a hardwood integrated board, a wood particle board, and a particle board, etc., and the water content of theboard body 1 is controled to be within 8% to 10% by weight. A plurality of sets of limiting connectors 3 are provided on theplastic frame 2. Twoadjacent board bodies 1 are fixed with each other by an engagement of corresponding limiting connectors 3 on the plastic frames 2 of theperipheries 13 of the board bodies. Thefirst groove 14 is provided on theperiphery 13 of the board body near theupper surface 101 of the board body, and the protrudingboss 15 having theinclined side surface 130 is formed between thetop surface 140 of the first groove and theupper surface 101 of the board body. An angle between theinclined side surface 130 and thetop surface 140 of the first groove is an acute angle, as shown inFIG. 3 . Specifically, the protrudingedge 131 is formed at the intersection of theinclined side surface 130 of the protrudingboss 15 and thetop surface 140 of the first groove. Theplastic frame 2 is provided under the protrudingboss 15 and embedded in thefirst groove 14. The cross-section of thefirst groove 14 has a shape of a horizontal dovetail groove having its opening facing outward. As shown inFIG. 4 , in the present embodiment, the cross-section of thefirst groove 14 has a horizontal U shape with its opening facing outward or a horizontal U shape with an acute angle and its opening facing outward. There are various shapes that could be applied to thefirst groove 14, which are not listed herein. An outer side wall of theplastic frame 2 and the protrudingedge 131 of the protrudingboss 15 are on the same vertical plane. The angle between theinclined side surface 130 and thetop surface 140 of the first groove ranges from 80° to 89°. Preferably, the angle α is 87°. - Since the blank of the
board body 1 is exposed to the natural environment during the processing, with the influence of temperature and humidity, wet makes the wood expand and dry makes it contract. However, since the density of a piece of wood varies at different parts, the deformation is also irregular, so the side wall of the protrudingboss 15 of theboard body 1 fitted with theplastic frame 2 is unsmooth, which will lead to a material leakage. In order to ensure that there is no gap between the side wall of the protrudingboss 15 of theboard body 1 at the wood-plastic fitting surface and the mold, the wood is machined to a certain extent to provide an inclination angle. If the inclination angle is greater than 90 degrees, the expected effect will not be achieved. If there is a sharp inclination, an unexpected gap will be left when two floor boards are assembled together, thereby affecting the appearance. The range of the inclination angle a provided by the comparison test is 80° to 89°. - In the injection molding of the floor board according to the present invention, protruding
boss 15 on theperiphery 13 of the board body is fitted with the inner wall of a mold. Since the protrudingboss 15 has theinclined side surface 130, the protrudingedge 131 of theinclined side surface 130 of the protrudingboss 15 and a side wall of the mold make an injection molding space isolated with theupper surface 101 of the board body to prevent the plastic material from overflowing to theupper surface 101 of the board body. After the injection molding, theplastic frame 2 is formed on theperiphery 13 of the board body, and theplastic frame 2 is partially embedded in thefirst groove 14 to enhance a firmness of theboard body 1 and theplastic frame 2. Meanwhile, theplastic frame 2 is provided under the protrudingboss 15 and the outer side wall of theplastic frame 2 and the protrudingedge 131 of the protrudingboss 15 are on the same vertical plane. Therefore, after the injection molding of theboard body 1, theplastic frame 2 is hidden under theboard body 1, and theplastic frame 2 is invisible by vertically viewing from theupper surface 101 of the board body, and the appearance of the floor board is not affected after assembling. No redundant plastic material is left on theupper surface 101 of the board body, and no secondary treatment is required. - As shown in
FIG. 2 , this embodiment is an optimized solution ofembodiment 1. The description of the present embodiment focuses on the improvements onembodiment 1, and the identical contents are not repeated herein. In the present embodiment, an area of theupper surface 101 of the board body is larger than an area of thebottom surface 102 of the board body, theperiphery 13 of the board body is located between the upper surface and the bottom surface, theperiphery 13 of the board body is provided with a stepped shape, thesecond groove 16 is provided on theperiphery 13 of the board body near thebottom surface 102 of the board body, and theplastic frame 2 is embedded in thesecond groove 16. The cross-section of thesecond groove 16 is a horizontal dovetail groove with its opening facing outward. As shown inFIG. 4 , in the present embodiment, the cross-section of thesecond groove 16 has a horizontal U shape with its opening facing outward or a horizontal U shape with an acute angle and its opening facing outward. There are various shapes can be applied to thesecond groove 16, which are not listed herein. The stepped shape is configured to set aside a space for the formation of the limiting connectors 3 for sliding assembling, and a sliding rail surface for the assembling of the limiting connectors 3 is formed on the step. Thesecond groove 16 is configured to make theplastic frame 2 partially embedded in thesecond groove 16 during the injection molding, thereby further enhancing the firmness of theboard body 1 and theplastic frame 2. - As shown in
FIG. 5 , this embodiment is an optimized solution ofembodiment 2. The description of the present embodiment focuses on the improvements onembodiment 2, and the identical contents are not repeated herein. In the present embodiment, theplastic frame 2 includes thebottom frame 21 and theside frame 22 provided inside thebottom frame 21 and integrally formed with thebottom frame 21. Each set of the limiting connectors 3 includes the first engagingmember 31 and the second engagingmember 32 which are adjacent to each other. The first engagingmember 31 protrudes outward from a side board of theside frame 22, and the first engagingmember 31 is connected to a bottom surface of thebottom frame 21. The second engagingmember 32 protrudes downward from the bottom surface of thebottom frame 21, and the first engagingmember 31 and the second engagingmember 32 on two sides of theside frame 22 are arranged in a staggered manner. - The
side frame 22 includes the first side board 221, thesecond side board 222, thethird side board 223, and thefourth side board 224.

In the longitudinal direction (i.e., the Y-axis direction inFIG. 5 ), the first engagingmember 31 and the second engagingmember 32 on both sides of theside frame 22 are arranged in the staggered manner, namely, the first engagingmember 31 on the outer side of thesecond side board 222 corresponds to the second engagingmember 32 on the outer side of thefourth side board 224, and the second engagingmember 32 on the outer side of thesecond side board 222 corresponds to the first engagingmember 31 on the outer side of thefourth side board 224. In the present application, the term “correspond” means that, when two floor boards are assembled, the first engagingportion 310 at the outer side of the first side board 221 of thefirst floor board 100 is matched and engaged with the second engagingmember 32 at the outer side of thethird side board 223 of thesecond floor board 200, and the second engagingmember 32 at the outer side of the first side board 221 of thefirst floor board 100 is matched and engaged with the first engagingportion 310 at the outer side of thethird side board 223 of thesecond floor board 200. - Specifically, a distance between the first engaging
member 31 in one set of limiting connectors 3 and the second engagingmember 32 in the adjacent set of limiting connectors 3 is greater than a length of the first engagingmember 31. The first engagingmember 31 and the second engagingmember 32 on the two sides of theside frame 22 are arranged in the staggered manner, so that the first engagingmember 31 and the second engagingmember 32 of the adjacent two floor boards are matched and engaged with each other. In the assembling, the same engaging members, i.e. the first engagingmembers 31 and the second engagingmembers 32, of the adjacent two floor boards are staggered, and the mating engaging members of the adjacent two floor boards are aligned and matched with each other. Then one of the two floor boards is side slid to make them assembled through a limiting function of the first engagingmember 31 and the second engagingmember 32, and a displacement is avoided. The installation process is quite simple, and floor boards are reusable. Moreover, it is unnecessary to distinct the left and right of the limiting connectors of the floor boards, so the installation efficiency is further improved, and the installation difficulty is reduced. - As shown in

Theboard body 1 is composed of a front board 11 provided on the upper surface and a back board 12 connected to the front board 11 and provided on the bottom surface, and the back board 12 is provided on the back surface of the front board 11. In the present embodiment, a hardwood of miscellaneous tree is selected as the raw material for the front board 11. For example, the wood may be a valuable wood such as an oak wood, an elm wood, a black walnut wood, etc., having a water content ranging from 8% to 10% by weight, a thickness ranging from 3 mm to 4 mm. The length and width should meet the requirements of the mold size of the injection molding machine after milling and shaping. A softwood of miscellaneous tree is selected as the raw material for the back board 12. For example, the softwood may be from a fast-growing wood species such as a pine wood, or a spruce wood, having a water content ranging from 8% to 11% by weight, and a thickness ranging from 10 mm to 15 mm. - The back board 12 is composed of a plurality of
board cores 120. A glue is evenly coated on the back surface of the front board 11. Theboard cores 120 are initially bonded to the back surface of the front board 11. Then, the front board 11 is placed in a pressing machine with the its back surface facing upward for pressing to obtain a unfinished double-layer solid wood board. The spacing betweenadjacent board cores 120 ranges from 0.5 mm to 1.5 mm to avoid problems of appearance and quality such as the curling up caused by the phenomenon that dry makes the wood contract and wet makes it expand. Thefirst groove 14 is provided at a periphery of the front board 11, thesecond groove 16 is provided at a periphery of the back board 12, and thebottom frame 21 is provided at a back surface of the front board 11. The back board 12 is provided in a receiving cavity surrounded by theside frame 22. The above embodiments are merely the preferred embodiments of the present invention, and there may be more variations in practical applications. For example, the back board 12 is an unbroken board instead of being spliced by a plurality ofboard cores 120. - Preferably, an outer edge of the
bottom frame 21 is aligned with an outer edge of the front board 11. - As shown in
FIGS. 7-8 , this embodiment is an optimized solution of embodiment 3. The description of the present embodiment focuses on the improvements on embodiment 3, and the identical contents are not repeated herein. In the present embodiment, thebottom surface 102 of the board body is provided with thewaterproof film 4, a cross-section of thewaterproof film 4 is U-shaped, and an outer edge of thewaterproof film 4 is located between thebottom frame 21 and theboard body 1. An end of the outer edge of thewaterproof film 4 is connected in thesecond groove 16 in an overlapping manner. Thewaterproof film 4 has a thickness ranging from 0.08 mm to 0.12 mm, and can withstand high temperatures. Thewaterproof film 4 may be a polyvinyl chloride (PVC)waterproof film 4. After thewaterproof film 4 is attached to thebottom surface 102 of the board body, the plastic frame can be formed on theperiphery 13 of the board body by the injection molding. In other embodiments, after applying a paint with a certain thickness on thebottom surface 102 of the board body, thewaterproof film 4 is provided on the paint layer, and it is controlled to make the paint have a thickness ranging from 0.05 mm to 0.25 mm after curing. In another embodiment, only the paint with a certain thickness is applied on thebottom surface 102 of the board body, and it is controlled to make the paint have a thickness ranging from 0.05 mm to 0.25 mm after curing without providing thewaterproof film 4. The above two methods can also provide the waterproof function for thebottom surface 102 of the board body, and the application of the base paint can improve the wear resistance of the bottom surface. - As shown in
FIG. 9 , this embodiment is an optimized solution of any one of embodiments 1-8. The description of the present embodiment focuses on the improvements on embodiments 1-8, and the identical contents are not repeated herein. In the present embodiment, theplate body 1 to which thewaterproof film 4 is attached or having itsbottom surface 102 coated with the paint is placed in thelower mold 6 in inversion, so theupper surface 101 of the board body is closely fitted with the surface of thelower mold 6. The first slidingblock 7 is pushed toward the left in the direction of the force F, so that the left and right sides of theboard body 1 are sandwiched between the first slidingblock 7 and the fixedside wall 61 of thelower mold 6. Similarly, the front and rear sides of theboard body 1 are sandwiched between the second sliding block (not shown inFIG. 9 ) and the fixedside wall 61 of thelower mold 6. The protrudingedge 131 of theperiphery 13 of the board body is fitted with the fixedside wall 61 of thelower mold 6, the first slidingblock 7, and the second sliding block, so that thefirst space 300 between the protrudingedge 131 of theperiphery 13 of the board body and theupper surface 101 of the board body is isolated with thesecond space 400 between the protrudingedge 131 of theperiphery 13 of the board body and thebottom surface 102 of the board body. After the upper mold is put on, the injection molding is performed in the injection molding machine. The molten plastic material is injected into thesecond space 400. After the mold is cooled and opened, theplastic frame 2 is formed at theperiphery 13 of the board body. Since thefirst space 300 is isolated with thesecond space 400 by the protrudingedge 131 of theperiphery 13 of the board body, and the molten plastic material cannot enter thefirst space 300 from thesecond space 400, after the injection molding, no redundant plastic material is left on theupper surface 101 of the board body, and no secondary treatment is required. Thus, the processes for manufacturing the floor board of rapid side-slide installation are reduced, and the production cost is lowered. After the injection molding, theupper surface 101 of the board body is painted to form thethird paint layer 5 on the upper surface, so as to achieve the decorative and waterproof properties of the upper surface. - In the present embodiment, the molten plastic material may be polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyoxymethylene, poly chromium carbonate, acrylic plastic, polyolefin and copolymer thereof, polysulfone, polyphenylene ether, a thermoplastic composed of chlorinated polyether, a hot melt adhesive, or a thermoplastic elastomer. The materials listed above are the commonly used thermoplastics, they can be applied in the present invention and achieve good effects.
- The above description merely refers to the preferred embodiments of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be considered as falling within the scope of the present invention.
