Description

Technical Field

[0001] The present invention relates to the technical field of thresholds, and particularly to an adjustable aluminum alloy zero-barrier threshold structure. Background Art

[0002] In the prior art, traditional threshold designs often have a large height difference problem. Especially for the passage of the elderly, the disabled, or wheelchair users, the height difference of the threshold is likely to cause passage obstacles. This height difference not only affects the barrier-free design of buildings but also brings inconvenience and potential safety hazards. Most existing threshold structures do not consider the adjustment requirements for different ground heights during design. Therefore, the height of the threshold is often fixed after installation and is difficult to adjust according to actual usage needs.

[0003] Aluminum alloy, as a lightweight, high-strength, and corrosion-resistant material, is widely used in threshold structures. However, despite the excellent physical properties of aluminum alloy, existing aluminum alloy threshold designs still face some problems. For example, many aluminum alloy thresholds lack an effective adjustment mechanism and cannot flexibly adjust according to the ground height difference, which makes them perform poorly in barrier-free design. In addition, existing aluminum alloy thresholds often lack effective guiding and supporting mechanisms during the adjustment process, resulting in instability, jamming, or deviation during height adjustment. This problem not only affects the installation accuracy and usage experience of the threshold but also increases the difficulty of later maintenance. Moreover, the connection components of many aluminum alloy threshold structures are relatively simple and lack sufficient stability, and may become loose or damaged during long-term use, resulting in the failure of the threshold function and affecting its service life.

[0004] Therefore, the present invention proposes an adjustable aluminum alloy zero-barrier threshold structure to solve the deficiencies of the prior art. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an adjustable aluminum alloy zero-barrier threshold structure, which solves the problem that traditional thresholds are difficult to flexibly adjust according to the ground height difference.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An adjustable aluminum alloy zero-barrier threshold structure includes two aluminum alloy profiles and two covers. On both sides of the interiors of the two aluminum alloy profiles, there are fixedly connected teeth, and on both sides of the exteriors of the two covers, there are provided a plurality of slots. The teeth are engaged with the slots. Between the bottom of the aluminum alloy profile and the cover, there are provided a guiding component and a strengthening component, and a connecting bar is provided between the two covers.

[0007] Preferably, the guiding assembly includes two groups of guiding columns. One group of guiding columns is fixedly connected to one side of the bottom of one of the cover plates, and the other group of guiding columns is fixedly connected to one side of the bottom of the other cover plate. The number of guiding columns in each group is two. Two guiding grooves are provided on one side of the top of the two aluminum alloy profiles, and the guiding columns are inserted and matched with the guiding grooves.

[0008] Preferably, the strengthening assembly includes two installation cavities. One installation cavity is provided on the other side of the top of one of the aluminum alloy profiles, and the other installation cavity is provided on the other side of the top of the other aluminum alloy profile. A moving plate is slidably connected to the inner side of the installation cavity. A strengthening plate is fixedly connected to the top of the moving plate. Strengthening grooves are provided on the other side of the bottom of the two cover plates, and the strengthening grooves are inserted and matched with the strengthening plates.

[0009] Preferably, a plurality of springs are fixedly connected between the bottom of the moving plate and the inner bottom wall of the installation cavity, and the plurality of springs are equidistantly distributed in the spring.

[0010] Preferably, two heat insulation strips are provided between the two aluminum alloy profiles.

[0011] Preferably, a heat insulation filling strip is provided between the two heat insulation strips.

[0012] Preferably, the heat insulation filling strip is made of polystyrene or polyurethane.

[0013] Preferably, a pre-buried part is provided at the bottom of the aluminum alloy profile.

[0014] The present invention provides an adjustable aluminum alloy zero-barrier threshold structure. It has the following beneficial effects:

[0015] 1. Through the cooperative design of the teeth and the slots, the present invention can adjust the threshold height according to different ground height differences, achieving a zero-barrier effect. This design not only eliminates the height difference problem of traditional thresholds but also ensures that different users, including those with mobility impairments, can easily enter and exit, improving the applicability and convenience of the threshold.

[0016] 2. By designing guiding grooves on the top of the aluminum alloy profile and guiding columns at the bottom of the cover plate, the present invention makes the threshold height adjustment process smooth and stable. The cooperation between the guiding columns and the guiding grooves effectively avoids the offset or jamming of the cover plate during the adjustment process, ensuring that the installation and use of the threshold are more accurate and convenient.

[0017] 3. The present invention enhances the connection strength between the cover plate and the aluminum alloy profile by designing reinforcing plates, reinforcing grooves, springs, etc. The reinforcing groove at the bottom of the cover plate is automatically inserted into the reinforcing plate at the top of the aluminum alloy profile to ensure a firm connection between the two. At the same time, the spring at the bottom of the moving plate provides an elastic thrust, making the contact surface between the cover plate and the aluminum alloy profile more fitting when adjusting the height of the cover plate, further enhancing the connection stability. This design effectively improves the stability and load-bearing capacity of the threshold, ensuring that the threshold remains stable during use and avoiding loosening or imbalance problems caused by external forces.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to the attachedFigure 1 -Attached Figure 8 The embodiment of the present invention provides an aluminum alloy adjustable zero-barrier threshold structure, comprising two aluminum alloy profiles 1 and two cover plates 3, wherein the bottom of the aluminum alloy profile 1 is provided with an embedded portion 2, the inner sides of the two aluminum alloy profiles 1 are fixedly connected with latch teeth 5, the outer sides of the two cover plates 3 are provided with a plurality of latch grooves 6, the latch teeth 5 are engaged with the latch grooves 6, a guide assembly and a reinforcement assembly are provided between the bottom of the aluminum alloy profile 1 and the cover plate 3, a connecting strip 4 is provided between the two cover plates 3, the guide assembly comprises two groups of guide columns 12, one group of the guide columns 12 is fixedly connected to one side of the bottom of one of the cover plates 3, and the other group of the guide columns 12 is fixedly connected to one side of the bottom of the other cover plate 3, and the number of the guide columns 12 in each group is two, and two guide grooves 13 are provided on one side of the top of the two aluminum alloy profiles 1. , the guide column 12 is plugged into the guide groove 13, the reinforcement component includes two installation cavities 7, one of the installation cavities 7 is opened on the other side of the top of one of the aluminum alloy profiles 1, and the other installation cavity 7 is opened on the other side of the top of the other aluminum alloy profile 1, the inner side of the installation cavity 7 is slidably connected with a movable plate 8, and the top of the movable plate 8 is fixedly connected with a reinforcement plate 9, and the other side of the bottom of the two cover plates 3 is provided with a reinforcement groove 11, and the reinforcement groove 11 is plugged into the reinforcement plate 9, and a plurality of springs 10 are fixedly connected between the bottom of the movable plate 8 and the inner bottom wall of the installation cavity 7, and the plurality of springs 10 are equidistantly distributed in the spring 10, and two thermal insulation strips 15 are arranged between the two aluminum alloy profiles 1, and a thermal insulation filling strip 14 is arranged between the two thermal insulation strips 15, and the material of the thermal insulation filling strip 14 is polystyrene or polyurethane.

[0029] Specifically, the aluminum alloy profile 1 is the core component of the threshold structure, which has high strength, corrosion resistance and excellent wear resistance. The bottom of the aluminum alloy profile 1 is provided with an embedded part 2, which is used to firmly fix the threshold structure on the ground foundation to ensure the stability of the threshold in long-term use. Between the two aluminum alloy profiles 1, there are placed insulation strips 15, which are respectively located on both sides of the aluminum alloy profile 1. The insulation filling strips 14 between the insulation strips 15 are made of high-quality polystyrene or polyurethane materials, which can effectively prevent the conduction of external temperature, improve the energy efficiency of the threshold, and ensure good comfort during the use of the threshold.

[0030] The cover plate 3 is the upper covering part of the threshold structure. Besides serving as a covering function, it also undertakes the function of adjusting the threshold height. Multiple card slots 6 are provided on the outer side of the cover plate 3, and through these card slots 6, a snap-fit connection is achieved with the teeth 5 inside the aluminum alloy profile 1, ensuring that the cover plate 3 can be adjusted according to the ground height difference. Between the two cover plates 3, a connecting bar 4 is provided, which plays a role in connecting and stabilizing the cover plate 3, preventing the cover plate 3 from shifting during use, and enhancing the stability of the overall structure.

[0031] On one side of the bottom of each cover plate 3, two groups of guide posts 12 are fixed, and each group includes two guide posts 12. These guide posts 12 are inserted into the guide grooves 13 at the top of the aluminum alloy profile 1 during installation. Through the plug-in fit, it is ensured that the cover plate 3 can move smoothly when adjusting the height, avoiding deviation or jamming.

[0032] On one side of the top of each aluminum alloy profile 1, an installation cavity 7 is provided, and a moving plate 8 is slidably connected inside the cavity. A reinforcing plate 9 is fixed to the top of the moving plate 8, and the reinforcing plate 9 cooperates with the reinforcing groove 11 at the bottom of the cover plate 3, significantly enhancing the connection strength between the cover plate 3 and the aluminum alloy profile 1.

[0033] To further improve the stability and flexibility of the threshold structure, multiple springs 10 are also designed in the enhancing assembly. These springs 10 are installed between the bottom of the moving plate 8 and the inner wall of the installation cavity 7 and are evenly distributed to provide the necessary elastic support. The elastic effect of the springs 10 makes the contact surface between the cover plate 3 and the aluminum alloy profile 1 closer, thereby enhancing the connection strength between the two.

[0034] The design of this threshold structure also pays special attention to the heat insulation effect. Through the reasonable layout of the heat insulation strip 15 and the heat insulation filling strip 14, the threshold can effectively isolate external heat and cold, maintaining the stability of the indoor temperature. The excellent performance of the heat insulation material not only improves the living comfort but also reduces the energy loss caused by the indoor-outdoor temperature difference, playing an energy-saving role.

[0035] After the installation and adjustment of the aluminum alloy adjustable zero-barrier threshold structure, it not only realizes the zero-barrier function and is suitable for various places requiring barrier-free design but also has a good heat insulation effect and improves the energy efficiency.

[0036] Working principle: First, assemble the aluminum alloy profile 1, the heat insulation strip 15, and the heat insulation filling strip 14 into a whole, and at the same time assemble the cover plate 3 and the connecting bar 4 into another whole. Then, firmly fix the embedded part 2 at the bottom of the aluminum alloy profile 1 to the ground foundation structure, and then stably install the aluminum alloy profile 1 to build the basic framework of the threshold.

[0037] Subsequently, the height of the cover plate 3 can be adjusted according to the height between the ground and the aluminum alloy profile 1 to achieve a zero-barrier threshold structure. The bottom guide posts 12 of the cover plate 3 can be inserted into the upper guide grooves 13 on the top of the aluminum alloy profile 1, and then the cover plate 3 moves towards the aluminum alloy profile 1, which plays a guiding role in the installation of the cover plate 3 and facilitates the installation of the cover plate 3. Since a plurality of card slots 6 are provided on both outer sides of the cover plate 3, after being adjusted to a suitable height, the card teeth 5 on both inner sides of the aluminum alloy profile 1 can be engaged with the corresponding card slots 6. The plurality of card slots 6 provide a flexible adjustment range. Regardless of the height difference between the ground and the aluminum alloy profile 1, the card teeth 5 can be engaged by selecting the card slots 6 adapted thereto, so that the cover plate 3 is in a suitable height position, eliminating the height difference barrier of the traditional threshold and achieving a zero-barrier effect. At the same time, the reinforcement groove 11 on the other side of the bottom of the cover plate 3 will be automatically inserted and matched with the reinforcement plate 9 protruding from the installation cavity 7 on the top of the aluminum alloy profile 1. The spring 10 at the bottom of the moving plate 8 provides a thrust force, and when the height of the cover plate 3 is adjusted, the contact surface on one side is more closely attached to the contact surface on one side of the aluminum alloy profile 1, further enhancing the connection strength between the cover plate 3 and the aluminum alloy profile 1 and ensuring the stable installation of the threshold.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
