Description

Technical Field

[0001] This utility model relates to the technical field of boardwalk splicing connectors, specifically to splicing connectors for wooden boardwalks in garden landscapes. Background Technology

[0002] Landscape wooden boardwalk splicing connectors refer to specialized metal or composite material components used in outdoor gardens, parks, wetlands, scenic areas, and other environments to connect and secure wooden boardwalk panels, such as those made of preservative-treated wood, wood-plastic composites, and carbonized wood. These connectors are typically concealed between or beneath the planks, serving to connect, secure, support, and adjust the boardwalk. They are generally made of stainless steel, aluminum alloy, or high-strength engineering plastics, possessing excellent corrosion resistance, aging resistance, and structural strength to withstand the damp, sun- and rain-exposed outdoor environment.

[0003] Common wooden boardwalk splicing connectors typically use a fixed structure, which cannot adjust the gap between boards according to environmental changes. They are prone to arching or cracking due to thermal expansion and contraction of the wood, affecting their service life. In addition, they mostly rely on screws or bolts for fastening, which makes the installation process cumbersome, requires special tools, and has low construction efficiency. Furthermore, the exposed fasteners are susceptible to corrosion, affecting aesthetics and safety. The overall connection method lacks convenience and adaptability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a splicing connector for wooden boardwalks in garden landscapes. The connector has an adjustable gap width to accommodate the expansion and contraction of wood, preventing arching and cracking. It requires no screws, locks upon pushing in, and is positioned with a reinforcing block and groove guide. Springs automatically lock it in place, making installation quick, precise, and reliable. This solves the problems of common wooden boardwalk connectors, which are fixed structures, cannot adjust the gap, are prone to arching and cracking due to wood expansion and contraction, rely on screws and bolts, are cumbersome to install, require special tools, are inefficient, have exposed fasteners that are susceptible to corrosion, affect aesthetics and safety, and lack convenience and adaptability.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a splicing connector for a wooden boardwalk in a garden landscape, including a splicing plate; it also includes a ratchet single lock assembly disposed in a groove on the right end face of the splicing plate, and a ratchet single lock assembly disposed on the left end face of the splicing plate. There are two splicing plates, and each splicing plate is respectively provided with a ratchet single lock assembly and a ratchet single lock assembly. The ratchet single lock assembly on the splicing plate is used to connect with the ratchet single lock assemblies on other splicing plates. The ratchet single lock assembly includes a replica ratchet set inside the splicing plate, and the ratchet single lock assembly includes a replica ratchet set at the left end of the splicing plate. There are two replica ratchets and two replica ratchet teeth. The rim of the replica ratchet teeth is provided with unidirectionally inclined teeth. The replica ratchet teeth are strip-shaped and their tooth shape is adapted to the teeth of the replica ratchet teeth.

[0006] Furthermore, the ratchet single-lock assembly includes a rotating rod rotatably mounted on the right end of the splicing plate, a replica ratchet located on the outside of the rotating rod, and a resistance-increasing pad located at the lower end of the rotating rod. The rotating rod can rotate to drive the replica ratchet to rotate, and the resistance-increasing pad is set to prevent the replica ratchet from easily rotating when the two splicing plates are spliced ​​together.

[0007] Furthermore, the upper end of the rotating rod is provided with a special-shaped groove, which is used to insert a locking rod after subsequent splicing, so that the rotating rod cannot rotate.

[0008] Furthermore, the ratchet single-lock assembly includes two docking frames installed on the left end face of the splicing plate, a connecting rod rotatably installed inside the docking frames, a replica ratchet fixed on the outside of the connecting rod, a spring installed on the docking frames, and a mounting plate installed on the other end of the spring. The mounting plate is connected to the replica ratchet, which is fixed elastically. When the replica ratchet engages with the replica ratchet wheel, the replica ratchet elastically resets to form a one-way snap-lock engagement.

[0009] Furthermore, the teeth of the ratchet and the tooth shape of the ratchet are both designed with an offset right angle. The force-bearing surface is a blocking surface that is approximately perpendicular to the direction of movement, and the guiding surface is a smooth inclined guide surface. This allows the components to slide in along the inclined surface and drive the corresponding parts to rotate and make way during the splicing process. When subjected to reverse tension, the vertical surface effectively prevents relative separation.

[0010] Furthermore, an external tool is inserted into the irregular groove to drive the rotating rod to rotate, which in turn drives the imitation ratchet to adjust the position of its teeth. When it engages with the imitation ratchet on the left end of the adjacent splicing plate, different engagement starting points allow for adjustment of the axial relative position between the two splicing plates, thereby controlling the width of the splicing gap.

[0011] Furthermore, a reinforcing block is provided on the left end face of the splicing panel, and a reinforcing groove is provided on the right end face of the splicing panel. The reinforcing groove and the reinforcing block are used for the jointing of two splicing panels. The reinforcing block on one splicing panel is inserted into the reinforcing groove of another splicing panel to form a mortise and tenon interlocking structure to enhance the structural strength.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. By rotating the rotating rod with an external tool, the imitation ratchet is driven to adjust the circumferential position of its teeth, changing the initial engagement point with the ratchet, thereby controlling the axial relative position between the two splicing boards and realizing the active adjustment of the gap width. The gap can be pre-adjusted according to the temperature and humidity changes in different seasons, such as leaving a small gap in the humid season and a large gap in the dry season, effectively coping with the expansion and contraction of wood and preventing arching, cracking or excessive gaps. 2. No screws, bolts or other tools are needed. The connection can be completed simply by pushing and connecting, achieving instant locking. This greatly improves on-site construction efficiency and reduces labor costs. The cooperation between the reinforcing block and the reinforcing groove plays a guiding and positioning role, avoiding problems such as misalignment and misalignment during the splicing process, improving installation accuracy and overall flatness. The ratchet assembly is pre-tensioned by a spring, and automatically springs back and engages after the ratchet slides past the tooth tip, achieving passive automatic locking. It is simple to operate and highly reliable. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 The garden landscape wooden boardwalk splicing connector in this embodiment includes a splicing plate 1; it also includes a ratchet single lock assembly disposed in the groove on the right end face of the splicing plate 1, and a ratchet single lock assembly disposed on the left end face of the splicing plate 1. There are two splicing plates 1, and each splicing plate 1 is respectively provided with a ratchet single lock assembly and a ratchet single lock assembly. The ratchet single lock assembly on the splicing plate 1 is used to dock with the ratchet single lock assemblies on other splicing plates 1.

[0017] In this embodiment, the connector can adjust the position of the ratchet by rotating it to change the starting point of engagement, thereby making the joint width adjustable. This adapts to the thermal expansion and contraction of the wood, preventing arching and cracking. At the same time, it does not require screws; it locks as soon as it is pushed in. With the guidance and positioning of the reinforcing block 6 and the groove, and the automatic rebound locking of the spring 9, the installation is quick, the alignment is accurate, and the operation is reliable.

[0018] Please see Figures 1-5 In this embodiment, in order to adjust the size of the gap by rotating the ratchet according to changes in weather humidity, and to prevent the wood from deforming and cracking due to expansion and contraction, the ratchet single lock assembly in this embodiment includes a replica ratchet 4 disposed in the splicing plate 1, and a ratchet single lock assembly includes a replica ratchet 4 disposed at the left end of the splicing plate 1. There are two replica ratchet 4 and two replica ratchet teeth 11. The rim of the replica ratchet teeth 11 is provided with unidirectional inclined teeth. The replica ratchet teeth 11 are strip-shaped and their tooth shape is adapted to the teeth of the replica ratchet 4.

[0019] In this embodiment, to achieve the ability to adjust the joint width by rotating the ratchet according to changes in weather humidity, preventing the wood from expanding and contracting and deforming, the splicing plate 1 is used to support the connecting structure and transmit loads. The ratchet single-lock assembly is installed on the right end of the splicing plate 1. By adjusting the position of the imitation ratchet 4, the engagement starting point is changed to achieve active control of the joint width, adapting to the thermal expansion and contraction of the wood and preventing arching and cracking. The ratchet single-lock assembly is set on the left end of the splicing plate 1. The engagement of the imitation ratchet 11 with the imitation ratchet 4 achieves a one-way locking function. The two imitation ratchet 4 and the two imitation ratchet 11 enhance the connection stability and load-bearing capacity. The imitation ratchet 4 has a rotatable tooth structure for adjusting the circumferential position. The imitation ratchet 11 is a strip-shaped, one-way inclined tooth shape that can match and engage with the imitation ratchet 4 to achieve instant locking upon pushing. The overall structure requires no tools for installation, splicing is quick, the gap is adjustable, and the connection is firm, making it suitable for the splicing needs of wooden boardwalks in outdoor environments with varying conditions.

[0020] It should be noted that when an external tool is inserted into the shaped groove, it drives the rotating rod 2 to rotate, causing the imitation ratchet 4 to adjust its tooth position. When it mates with the imitation ratchet 11 on the left end of the adjacent splicing plate 1, different engagement starting points adjust the axial relative position between the two splicing plates 1, thereby controlling the width of the splicing gap. The external tool is used to apply rotational torque to drive the component's movement. The shaped groove receives the insertion of the external tool and transmits rotational power. The rotating rod 2, as a transmission shaft, transmits the rotational motion to the imitation ratchet 4. The imitation ratchet 4 adjusts the engagement starting point by changing the circumferential position of its teeth. The tooth position determines the initial contact point and axial offset during splicing. The splicing plate 1, as a load-bearing structure, realizes the connection and fit between the plates. The imitation ratchet 11 has... The unidirectional inclined tooth profile allows for unidirectional forward engagement. The imitation ratchet 11 rotates and repositions under pressure, then springs back and locks after passing the apex. The spring 9 provides a restoring force to enable the imitation ratchet 11 to complete the automatic engagement action. The mounting plate 10 connects the spring 9 and the imitation ratchet 11 to transmit force. The docking frame 7 supports the connecting rod 8 and the spring 9 to maintain the stability of the component structure. The connecting rod 8 serves as the rotation axis, allowing the imitation ratchet 11 to rotate flexibly. The resistance pad 3 increases the rotational resistance of the rotating rod 2 to prevent the imitation ratchet 4 from rotating accidentally. The reinforcing block 6 and the reinforcing groove 5 cooperate to form a lateral limiting structure to improve splicing accuracy. The reinforcing groove 5 accommodates the reinforcing block 6 to achieve alignment and fitting between the splicing plates 1. The width of the splicing gap is actively controlled by adjusting the engagement position.

[0021] Please see Figures 1-5In this embodiment, to achieve a lock that doesn't require screwing and locks with a simple push, with blocks and slots to help align it quickly and stably, the ratchet single-lock assembly in this embodiment includes a rotating rod 2 rotatably mounted on the right end of the splicing plate 1, a replica ratchet 4 disposed on the outside of the rotating rod 2, and a resistance-increasing pad 3 disposed on the lower end of the rotating rod 2. The rotating rod 2 can rotate to drive the replica ratchet 4 to rotate. The resistance-increasing pad 3 prevents the replica ratchet 4 from easily rotating when the two splicing plates 1 are spliced. The ratchet single-lock assembly includes two docking frames 7 mounted on the left end face of the splicing plate 1, a connecting rod 8 rotatably mounted inside the docking frames 7, a replica ratchet 11 fixed on the outside of the connecting rod 8, a spring 9 mounted on the docking frames 7, and a mounting plate 10 mounted on the other end of the spring 9. The mounting plate 10 is connected to the replica ratchet 11. 1. Fixed by elastic means, when the imitation ratchet 11 is connected to the imitation ratchet 4, the imitation ratchet 11 elastically resets to form a one-way snap-fit ​​engagement. The teeth of the imitation ratchet 4 and the tooth shape of the imitation ratchet 11 are both designed with an offset right angle. Its force-bearing surface is a blocking surface that is approximately perpendicular to the direction of movement, and the guiding surface is an inclined and smooth guide slope, which allows it to slide in along the slope and drive the corresponding parts to rotate and make way during the splicing process. When subjected to reverse tension, the vertical surface effectively prevents relative separation. A reinforcing block 6 is provided on the left end face of the splicing plate 1, and a reinforcing groove 5 is provided on the right end face of the splicing plate 1. The reinforcing groove 5 and the reinforcing block 6 are used for the connection of two splicing plates 1. The reinforcing block 6 on one splicing plate 1 is inserted into the reinforcing groove 5 of the other splicing plate 1 to form a mortise and tenon interlocking structure to enhance the structural strength.

[0022] In this embodiment, the rotating rod 2 receives the rotation operation and drives the imitation ratchet 4 to achieve angle adjustment. The imitation ratchet 4 has teeth on its outer side, which mesh to achieve connection and locking functions. The resistance pad 3 is installed at the lower end of the rotating rod 2 to increase rotational resistance and prevent the imitation ratchet 4 from rotating accidentally. The docking frame 7 serves as a support structure to fix the connecting rod 8 and the spring 9 and provide a mounting base. The connecting rod 8 acts as a rotary bearing to carry the imitation ratchet 11 and realize its rotational freedom. The imitation ratchet 11 has a unidirectional tooth shape to achieve a unidirectional locking function during docking. The spring 9 provides elastic restoring force so that the imitation ratchet 11 can automatically reset after being compressed. The mounting plate 10 connects the spring 9 and the... The imitation ratchet 11 transmits elastic force to achieve the reset action. The imitation ratchet 4 has an offset right-angle design with a beveled guide surface for easy advancement and a vertical force-bearing surface to prevent disengagement and improve locking reliability when subjected to reverse force. The tooth shape of the imitation ratchet 11 matches that of the imitation ratchet 4 to achieve smooth sliding and reliable locking. The reinforcing block 6 is set at the left end of the splicing plate 1 to be inserted into the reinforcing groove 5 of the adjacent plate. The reinforcing groove 5 is opened at the right end of the splicing plate 1 to accommodate the reinforcing block 6 to form a fitting structure. The reinforcing block 6 and the reinforcing groove 5 cooperate to form a mortise and tenon connection to enhance the overall structural strength. The splicing plate 1 serves as the main component to support all parts and realize quick connection between plates.

[0023] It should be noted that the upper end of the rotating rod 2 has a special groove. The special groove is used to insert the locking rod after subsequent splicing, so that the rotating rod 2 cannot rotate.

[0024] The working principle of the above embodiments is as follows: During use, first align the two splicing plates 1 during installation. Initial positioning is achieved by inserting the reinforcing block 6 into the reinforcing groove 5, ensuring no misalignment during splicing. Then, push the splicing plate 1 so that the imitation ratchet 4 on the right end contacts the imitation ratchet tooth 11 on the left end. The inclined surface of the imitation ratchet 4 pushes the imitation ratchet tooth 11 to rotate, compressing the spring 9. When the tooth passes the tooth tip, the spring 9 releases its elasticity, causing the mounting plate 10 and the imitation ratchet tooth 11 to spring back, forming a snap-fit ​​engagement, achieving immediate locking upon insertion. After connection, if the gap width needs adjustment, an external tool can be inserted into the irregular groove at the upper end of the rotating rod 2. Rotating the rotating rod 2 drives the imitation ratchet 4 to adjust the circumferential position of the teeth, changing the engagement starting point with the imitation ratchet tooth 11, thereby controlling the axial distance between the two plates and achieving the purpose of adjusting the splice. After adjustment, remove the tool. Finally, insert the locking rod into the irregular groove to restrict the rotation of the rotating rod 2, preventing loosening during use. The entire operation requires no screws, is quick to install, accurately positioned, and firmly connected, adapting to changes in wood expansion and contraction.

[0025] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
