Description

Technical Field

[0001] The present invention relates to the technical field of plastic wood boards, and more particularly to a plastic wood board mounting column and a plastic wood board assembly. Background Art

[0002] Plastic wood board, or wood plastic board, is a high-tech, green and environmentally friendly new decorative material mainly made of wood (wood cellulose, plant cellulose) as the base material with thermoplastic polymer materials (plastics) and processing aids, which are mixed evenly and then heated and extruded by mold equipment. It has the performance and characteristics of both wood and plastic and is a new composite material that can replace wood and plastic.

[0003] Based on the waterproof and moisture-proof properties of plastic wood boards, it fundamentally solves the problem that wooden products are prone to rotting, swelling and deformation after absorbing water in humid and watery environments. Therefore, it can be used in environments where traditional wooden products cannot be used, especially for forming outdoor fence structures.

[0004] Outdoor fences generally include mounting posts and plastic wood panels installed between two adjacent mounting posts. In order to adapt to the diversity of outdoor terrain, the mounting posts are generally provided with grooves on the three outer walls for inserting the ends of the plastic wood panels. In this way, the plastic wood panels can be adaptively selected to be connected to the mounting posts, forming a straight or curved fence structure. At the same time, in order to prevent the plastic wood panels from falling off and improve the installation stability of the plastic wood panels, a clamping structure is generally provided between the ends of the plastic wood panels and the mounting posts to prevent the plastic wood panels from lateral separation. For example, in a new type of semi-enclosed fence disclosed in Chinese patent application number CN201920667614.3, a clamping slot extending along the length of the pillar and having a cross-shaped cross-section is provided, and a plurality of spaced-apart wood-plastic fence panel assemblies are clamped into the clamping slot.

[0005] It should be noted that: at the same time of installation, generally only the grooves on two side walls of the installation column will have plastic wood boards installed. At this time, the grooves on the remaining side walls are open structures without panels installed. As a result, outdoor dust, debris, and rainwater will enter the grooves from the groove openings, causing dirt to accumulate inside the grooves. In particular, dirt is easily accumulated in the card slots used to adapt to the card slots for connecting plastic wood boards. This not only easily causes erosion to the installation column and shortens the service life of the installation column, but also when the installation position of the plastic wood board needs to be adjusted later, the plastic wood board cannot be directly inserted into the card slot due to the accumulation of debris, and additional cleaning must be performed, which is very troublesome. Summary of the Invention

[0006] The purpose of the present invention is to address the shortcomings of the existing technology and provide a plastic wood board installation column equipped with a protective cover, which can shield and protect the insertion slots on the installation column where no panels are installed, and prevent external debris, rainwater, etc. from entering the insertion slots and the card slots, thereby reducing the possibility of foreign objects accumulating in the insertion slots and corroding the installation columns; at the same time, when the installation position of the plastic wood board needs to be adjusted, the installation space can be released by removing the protective cover, which reduces the need for cleaning and improves the convenience of adjusting the installation position of the plastic wood board.

[0007] On the basis of the above, a plastic wood board assembly using the above plastic wood board mounting column is provided.

[0008] The technical solutions of the present invention are as follows:

[0009] A plastic wood board mounting column, used for mounting a board provided with a clamping portion, the mounting column comprising:

[0010] The column comprises a plurality of outer side surfaces provided with insertion slots for inserting the plate, wherein the insertion slots comprise a first side wall and a second side wall which are arranged opposite to each other;

[0014] In the above scheme, in order to solve the problem that foreign debris, rainwater, etc. easily enter and accumulate in the insertion slots where no panels are installed, especially in the first and second card slots provided on the side walls of the insertion slots, resulting in the accumulation of foreign objects in the card slots, which occupies the installable space of the panels on the column, hindering the adjustment of the panel installation position, and corroding the column, a protective cover is provided that is detachably inserted into the insertion slots. During installation, depending on which outer side surface of the column the panel needs to be installed on, the protective cover located at that outer side surface can be removed to release the installation space for the panel, while the insertion slots on the outer sides where no panels are installed are installed with protective covers, which can prevent foreign debris, rainwater, etc. from entering the insertion slots and card slots, thereby reducing the possibility of foreign objects accumulating in the insertion slots and corroding the installation column. At the same time, when the installation position of the plastic wood board needs to be adjusted, the installation space can be released by removing the inserted protective cover, which reduces the need for cleaning and improves the convenience of adjusting the installation position of the plastic wood board.

[0015] Further as a preferred embodiment, the connecting portion includes a covering section arranged near the slot of the insertion slot, and a first connecting section and a second connecting section respectively connected to the two ends of the covering section, the first connecting section being connected to the first plug-in portion, and the second connecting section being connected to the second plug-in portion.

[0016] As a further preferred solution, a third card slot is provided on the first side wall, and the third card slot is placed between the bottom surface of the insertion slot and the first card slot;

[0017] A fourth card slot is provided on the second side wall, and the fourth card slot is located between the bottom surface of the slot and the second card slot;

[0018] The third card slot and the fourth card slot together form a second plug-in structure for connecting with the card slot of the panel.

[0019] As a further preferred solution, an accommodating space capable of accommodating the connecting portion of the protective cover is formed between the first plug-in structure and the second plug-in structure.

[0020] As a further preferred solution, the column includes a support rod and a sleeve member sleeved on the support rod, and the insertion groove is provided on the outer side wall of the sleeve member.

[0021] As a further preferred solution, a mounting seat is provided at the bottom of the support rod, and a connecting hole for installing a connecting piece is provided on the mounting seat.

[0022] As a further preferred solution, the mounting seat is provided with a plurality of upwardly protruding limiting portions, and the limiting portions are provided with threaded holes for threaded installation of fastening screws, and the fastening screws are used to fasten the sleeve member.

DETAILED DESCRIPTION

[0044] The present invention is specifically described below with reference to the embodiments:

[0045] Example 1:

[0046] A plastic wood board installation column, refer to the attached Figure 1 To the attached Figure 10 , including a column 1 extending vertically. In this embodiment, the column 1 is a square structure with four outer sides, three of which are provided with insertion slots 1b1 opening outward. Figure 3 , Attachment Figure 4 As shown, the insertion slot 1b1 is a vertically extending strip-shaped slot that runs through the top and bottom. During installation, the end of the plate 2 is inserted downwardly into the insertion slot 1b1 from the upper opening of the insertion slot 1b1. The two opposing side walls of the insertion slot 1b1 are the first side wall 1b11 and the second side wall 1b12.

[0047] Furthermore, there is a transverse snap-fit ​​structure between the end of the panel 2 inserted in the insertion slot 1b1 and the column 1 to prevent the panel 2 from laterally detaching from the insertion slot 1b1; therefore, a first plug-in structure is provided on the column 1 to adapt to the snap-fit ​​portion provided at the end of the panel 2.

[0048] Specifically, as attached Figure 7 As shown, a first clamping portion 201 is protrudingly provided on one side of the plate 2 close to the first side wall 1b11, and a second clamping portion 202 is protrudingly provided on one side of the plate 2 close to the second side wall 1b12. The first clamping portion 201 and the second clamping portion 202 together form the clamping portion of the plate 2.

[0049] Suitable, as attached Figure 1 As shown, a first clipping slot 1b13 extending vertically and extending vertically through the first side wall 1b11 is provided, and a second clipping slot 1b14 extending vertically and extending vertically through the second side wall 1b12 is provided. The first clipping slot 1b13 and the second clipping slot 1b14 together form a first plug-in structure. When the end of the panel 2 is inserted downwardly into the insertion slot 1b1 through the upper opening of the insertion slot 1b1, the first clipping portion 201 is adapted to be inserted downwardly into the first clipping slot 1b13 through the upper opening of the first clipping slot 1b13, and the second clipping portion 202 is adapted to be inserted downwardly into the second clipping slot 1b14 through the upper opening of the second clipping slot 1b14.

[0050] It should be noted that: Figure 5 , Attachment Figure 6 As shown, the above-mentioned column 1 generally only has two outer sides equipped with plates 2, so that the insertion slot 1b1 on the remaining outer side is open. Outdoor dust, debris and rainwater will enter the insertion slot 1b1 from the slot opening of the insertion slot 1b1, causing dirt to accumulate inside the insertion slot 1b1, especially dirt is easily accumulated in the first card slot 1b13 and the second card slot 1b14 used to adapt to the card plate 2.

[0051] Based on this, a protective cover 3 with a strip-shaped structure extending vertically is added in this embodiment. By inserting the protective cover 3 downward into the insertion slot 1b1 from the upper end opening of the insertion slot 1b1, the internal space of the insertion slot 1b1 is blocked from the external space.

[0052] Specifically, as attached Figure 1 and attached Figure 4As shown, based on the number and position of the insertion slots 1b1 on the column 1, three protective covers 3 are adapted to be installed on one column 1 in this embodiment. Each protective cover 3 is removably inserted into one insertion slot 1b1 via an inserting portion that matches the clamping portion of the plate 2. Specifically, the inserting portion includes a first inserting portion 301 adapted to be inserted into the first clamping slot 1b13 and a second inserting portion 302 adapted to be inserted into the second clamping slot 1b14. A connecting portion 303 connects the first inserting portion 301 and the second inserting portion 302.

[0053] In this way, as attached Figure 4 As shown, when a panel 2 needs to be installed in a slot 1b1 on a particular outer side, the protective cover 3 inserted in that slot 1b1 can be pulled upward and removed, freeing up space in the slot 1b1 and allowing the end of the panel 2 to be inserted into the slot 1b1. Meanwhile, the protective covers 3 remain inserted in the remaining slots 1b1 where no panel 2 is required, preventing foreign matter, rainwater, etc. from entering the slot 1b1 and the first and second mounting slots 1b13 and 1b14.

[0054] As attached Figure 1 As shown, the connecting portion 303 includes a covering segment 3031 positioned near the notch of the insertion slot 1b1, and a first connecting segment 3032 and a second connecting segment 3033 connected to the ends of the covering segment 3031. The first connecting segment 3032 connects to the first plug-in portion 301, and the second connecting segment 3033 connects to the second plug-in portion 302. Positioning the covering segment 3031 near the notch of the insertion slot 1b1 increases the space covered by the connecting portion 303 over the insertion slot 1b1, thereby achieving a better barrier effect.

[0055] Furthermore, as attached Figure 2 As shown, a third clipping slot 1b15 extending vertically and extending vertically through the first side wall 1b11 is provided. This slot is positioned between the bottom surface 1b17 of the insertion slot 1b1 and the first clipping slot 1b13. A fourth clipping slot 1b16 extending vertically and extending vertically through the second side wall 1b12 is provided. This slot is positioned between the bottom surface 1b17 and the second clipping slot 1b14. Together, the third and fourth clipping slots 1b15 and 1b16 form a second plug-in structure for connecting with the clipping portion of the panel 2. When the end of the plate 2 is inserted downward into the insertion slot 1b1 from the upper end opening of the insertion slot 1b1, the first clamping portion 201 can be adapted to be inserted downward into the third clamping slot 1b15 from the upper end opening of the third clamping slot 1b15, and the second clamping portion 202 can be adapted to be inserted downward into the fourth clamping slot 1b16 from the upper end opening of the fourth clamping slot 1b16.

[0056] Specifically, the first plug-in structure and the second plug-in structure have the same structure, but are arranged at different positions of the plug-in slot 1b1.

[0057] In this way, as attached Figure 7 , Attachment Figure 9 and attached Figure 10 As shown, the clamping portion of the panel 2 can be selectively connected to the first plug-in structure or the second plug-in structure, so that the connection position of the panel 2 on the column 1 can be adjusted, and then the length of the plastic wood board assembly below can be adjusted, so that certain adaptive adjustments can be made according to the specific installation environment.

[0058] Similarly, the protective cover 3 may be inserted into the insertion slot 1 b 1 by inserting the insertion portion of the protective cover 3 into the second insertion structure.

[0059] Based on this, and further considering that plastic wood board mounting columns are primarily used for outdoor installation, it is difficult to transport or store the disassembled protective cover 3. Therefore, by adjusting the size of the connecting portion 303 of the protective cover 3 and the spacing between the first plug-in structure and the second plug-in structure, a space is formed between the first plug-in structure and the second plug-in structure to accommodate the connecting portion 303 of the protective cover 3.

[0060] In this way, as attached Figure 8 As shown, when the left end of the right panel 2 is inserted into the insertion slot 1b1 on the right side of the column 1, and the clamping portion at the left end of the panel 2 is connected to the first plug-in structure, the protective cover 3 originally removed from the first plug-in structure can be plugged into the second plug-in structure to insert the protective cover 3 into the insertion slot 1b1, without the need to carry and place the protective cover 3 separately.

[0061] Furthermore, as attached Figure 8 As shown, the structure and size of the connecting portion 303 in the protective cover 3 can be further adjusted according to the end structure of the panel 2; or the end structure and size of the panel 2 can be adjusted according to the structure of the connecting portion 303 in the protective cover 3, so that the protective cover 3 plugged into the second plug-in structure forms a transverse support structure that fits the panel 2 plugged into the first plug-in structure.

[0062] As attached Figure 3As shown, the column 1 includes a support rod 1a and a sleeve member 1b. A mounting seat 1a1 is provided at the bottom of the support rod 1a. The mounting seat 1a1 is provided with a connection hole 1a11 for mounting a connector (e.g., a screw). This allows the support rod 1a to be fixed to the ground using screws, eliminating the need for buried piles, making installation more convenient. The sleeve member 1b is fitted onto the support rod 1a, and a mounting slot 1b1 is provided on the outer wall of the sleeve member 1b. In this way, if the external sleeve member 1b becomes damaged, it can be directly replaced without having to replace the entire mounting column, reducing the cost of subsequent maintenance and replacement and improving the convenience of replacement.

[0063] As attached Figure 3 and attached Figure 4 As shown, mounting base 1a1 is provided with a plurality of upwardly protruding stoppers 1a12, each of which is provided with threaded holes for fastening screws to be screwed in and secure sleeve member 1b. Specifically, the threaded ends of the fastening screws pass through the stoppers 1a12 and are screwed into or pressed against sleeve member 1b, thereby positioning and securing sleeve member 1b to support rod 1a and enhancing the secure installation of sleeve member 1b.

[0064] As attached Figure 4 As shown, the top of the column 1 is connected to a top cover 4 that covers the column 1 from above to prevent rainwater and the like from flowing into the column 1 through the opening at the top of the column 1.

[0065] Example 2:

[0066] Based on implementation 1, a plastic wood board assembly for outdoor enclosure, refer to the attached Figure 5 To the attached Figure 10 , including several columns 1, several panels 2 preferably made of plastic wood boards, and several protective covers 3.

[0067] Specifically, as attached Figure 7 , Attachment Figure 9 , Attachment Figure 10 As shown, several columns 1 are placed at intervals, each plate 2 is installed between two adjacent columns 1, and the end of the plate 2 is adapted to be inserted into the insertion slot 1b1 of a column 1 close to the end, and the end of the plate 2 is also provided with a clamping portion formed by a first clamping portion 201 and a second clamping portion 202, which is adapted to be inserted into the first plug-in structure or the second plug-in structure; and a protective cover 3 can be detachably inserted into the insertion slot 1b1 of any column 1 where the plate 2 is not installed.

[0068] Furthermore, as attached Figure 8As shown, when the panel 2 is adapted to be plugged into the first plug-in structure, there is a protective cover 3 adapted to be plugged into the second plug-in structure. At the same time, the size structure of the protective cover 3 is adjusted according to the end face structure of the panel 2, so that the protective cover 3 adapted to be plugged into the second plug-in structure is laterally connected to the end face of the panel 2, and the protective cover 3 is used as a lateral support structure for the left / right end faces of the panel 2, thereby reducing the possibility of the first clamping part 201 and the second clamping part 202 being broken after the panel 2 is subjected to lateral force.
