Description

Technical Field

[0001] This application relates to the field of end caps, and more specifically, to an end cap that is universal for co-extruded wood-plastic composites. Background Technology

[0002] Co-extruded wood-plastic square tubes need to be sealed with end caps to prevent external debris from entering the tubes and to make them more aesthetically pleasing. However, the end caps require a high degree of tightness during sealing and are not easily damaged during installation and disassembly.

[0003] Existing technologies often use sealant to fix the end caps, which is cumbersome. Now, a universal end cap for co-extruded wood-plastic composites is provided. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a universal end cap for co-extruded wood-plastic square tubes, comprising: an end cap body mounted on a co-extruded wood-plastic square tube. A common type of end cap for co-extruded wood-plastic composites also includes, The first snap-fit ​​structure has several sets distributed along the upper end face of the head body. Each group of first snap-fit ​​structures consists of two first snap-fit ​​plates symmetrically distributed from left to right. The second snap-fit ​​structure has several sets distributed along the upper end face of the head body. Each set of the second snap-fit ​​structure consists of two second snap-fit ​​plates symmetrically distributed front and back. In each of the first snap-fit ​​structures, the first snap-fit ​​plates are fixedly connected to each other with a first protrusion close to one end face; in each of the second snap-fit ​​structures, the second snap-fit ​​plates are fixedly connected to each other with the first protrusion close to one end face; in each of the first snap-fit ​​structures, the first snap-fit ​​plates are fixedly connected to each other with two second protrusions away from one end face; in each of the second snap-fit ​​structures, the second snap-fit ​​plates are fixedly connected to each other with two second protrusions away from one end face.

[0006] Furthermore, The end face of the end cap body that does not contact the co-extruded wood-plastic square tube is provided with a brushed texture that is consistent with the surface texture of the co-extruded wood-plastic square tube.

[0007] Furthermore, The first snap-fit ​​plate and the second snap-fit ​​plate are fixedly connected to the head body.

[0008] Furthermore, Both the first and second protrusions are made of plastic, which can deform slightly under force to prevent damage when the end cap is inserted into the square tube, and can increase the tightness through deformation.

[0009] Furthermore, The first snap-fit ​​plate and the second snap-fit ​​plate are fixedly connected to an mounting plate. The mounting plate is fixedly connected to the end cap body through a plurality of mounting structures provided on the end cap body. When the first snap-fit ​​plate and the second snap-fit ​​plate are damaged, the end cap body can be used by replacing the mounting plate.

[0010] Furthermore, The installation structure includes a fixing block fixedly connected to the upper end face of the head body, a sliding plate slidably connected to the fixing block, and a traction plate fixedly connected to the end face of the fixing block away from the center point of the upper end face of the head body. Magnetic blocks are fixedly connected to the end faces of the traction plate and the fixing block that are close to each other. The two magnetic blocks can attract each other, thereby limiting the traction plate when the sliding plate limits the installation plate.

[0011] The beneficial effects of this application are as follows: It provides a universal end cap for co-extruded wood-plastic square tubes. The first protrusion can be locked onto the inner hole of the square tube when the end cap is connected to the square tube, thereby improving the tightness. The second protrusion can increase the strength when deforming inward, and at the same time make the end cap less likely to break when pulled outward. Attached Figure Description

[0017] It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0018] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are used only to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0019] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0020] It should be noted that the terms "front," "back," "left," and "right" used in this disclosure are supplementary. Figure 1 The concepts described are illustrative and not intended to limit the direction of use or the performance of this disclosure.

[0021] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example 1, refer to Figures 1-3A universal end cap for co-extruded wood-plastic square tubes includes: an end cap body 11 mounted on a co-extruded wood-plastic square tube; the upper end of the end cap body 11 is provided with several sets of first snap-fit ​​structures distributed along the upper surface of the end cap body 11, each set of first snap-fit ​​structures consisting of two first snap-fit ​​plates 12 symmetrically distributed laterally; the upper surface of the end cap body 11 is provided with several sets of second snap-fit ​​structures distributed along the upper surface of the end cap body 11, each set of second snap-fit ​​structures consisting of two second snap-fit ​​plates 13 symmetrically distributed front-backward; in each set of first snap-fit ​​structures, the first snap-fit ​​plates 12 are fixedly connected to each other at one end face with a first protrusion 1. 5. In each group of the second snap-fit ​​structure, the second snap-fit ​​plates 13 are fixedly connected to the first protrusion 15 close to one end face; in each group of the first snap-fit ​​structure, the first snap-fit ​​plates 12 are fixedly connected to two second protrusions 14 far away from one end face; in each group of the second snap-fit ​​structure, the second snap-fit ​​plates 13 are fixedly connected to two second protrusions 14 far away from one end face. The first protrusion 15 can be snapped into the inner hole of the square tube when the end cap is connected to the square tube, thereby improving the tightness and offsetting thermal expansion and contraction deformation during use without falling off. The second protrusion 14 can increase the strength when deforming inward, and at the same time make the end cap less likely to break when pulled outward.

[0023] The end face of the head body 11 that does not contact the co-extruded wood-plastic square tube is provided with a brushed texture that is consistent with the surface texture of the co-extruded wood-plastic square tube, so that the overall visual effect of the product is consistent.

[0024] The first snap-fit ​​plate 12 and the second snap-fit ​​plate 13 are fixedly connected to the end cap body 11.

[0025] Both the first protrusion 15 and the second protrusion 14 are made of plastic, which can deform slightly when subjected to force to avoid damage when the end cap is inserted into the square tube, and can increase the tightness through deformation.

[0026] Example 2, reference Figure 4-6 The difference from Example 1 is that: The first snap-fit ​​plate 12 and the second snap-fit ​​plate 13 are fixedly connected to the mounting plate 16. The mounting plate 16 is fixedly connected to the end cap body 11 through a plurality of mounting structures 20 provided on the end cap body 11. When the first snap-fit ​​plate 12 and the second snap-fit ​​plate 13 are damaged, the end cap body 16 can be replaced for use.

[0027] The installation structure 20 includes a fixing block 21 fixedly connected to the upper end face of the head body 11, a sliding plate 22 slidably connected to the fixing block 21, and a traction plate 23 fixedly connected to the end face of the fixing block 21 away from the center point of the upper end face of the head body 11. Magnetic blocks 24 are fixedly connected to the end faces of the traction plate 23 and the fixing block 21 that are close to each other. The two magnetic blocks 24 can attract each other, thereby limiting the traction plate 23 when the sliding plate 22 limits the installation plate 16. Magnetic adsorption limiting is a common technical means in this field. For example, a furniture design dimension measuring device with publication number CN115875582B uses the magnetic attraction between a magnetic limiting block and a magnetic card block, and cooperates with a first elastic element to squeeze the slider into the magnetic limiting block for limiting.

[0028] The end of the sliding plate 22 away from the traction plate 23 is chamfered to facilitate pushing the mounting plate 16 to fit tightly against the end cap body 11 when the sliding plate 22 moves.

[0029] By manually moving the traction plate 23, the sliding plate 22 can be moved to cooperate with the end cap body 11 to fix the mounting plate 16, or to contact and fix the mounting plate 16, thereby completing the installation and disassembly of the mounting plate 16.

[0030] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
