Description

Technical Field

[0001] This utility model belongs to the field of drainage ditch splicing and installation technology, specifically, it relates to an adjustable-angle drainage ditch module connecting buckle. Background Technology

[0002] In municipal construction, road engineering, and landscaping, drainage ditch systems are widely used for the collection and discharge of rainwater and wastewater. Traditional drainage ditch modules typically use straight connections or fixed angle connectors, which are simple but lack flexibility. In complex terrain or situations requiring reversal, current technology mainly relies on prefabricated connectors with specific angles or on-site cutting and adjustment. This not only increases the variety of materials in stock but may also lead to insufficient strength and reduced sealing performance at the joints. Especially in areas with uneven ground or a risk of settlement, rigid connections are prone to breakage or deformation at the joints due to stress concentration. Currently available adjustable connectors mostly use rubber flexible connections or metal hinge structures. The former's sealing performance is prone to deterioration over time, while the latter is prone to failure due to corrosion. At the same time, the installation of existing connectors usually requires specialized tools and techniques, increasing construction difficulty and time costs. In addition, traditional connection methods are extremely inconvenient for later maintenance and replacement. Once damage occurs, it often requires the replacement of the entire drainage ditch module, resulting in unnecessary waste of resources and environmental damage.

[0003] In summary, existing drainage ditch module connection structures can typically only achieve connections at fixed angles, making it difficult to adapt to changes in terrain or complex pipe network design requirements. Furthermore, the connection strength is insufficient, making it prone to loosening or breakage due to factors such as ground settlement and temperature changes, which in turn affects the overall function and service life of the drainage system. Utility Model Content

[0004] In view of this, the present invention provides an adjustable angle drainage ditch module connecting buckle, which can solve the problem that existing drainage outlet module connecting buckles cannot be adjusted according to changes in terrain.

[0005] This utility model is implemented as follows:

[0006] This utility model provides an adjustable-angle drainage ditch module connecting buckle, comprising: a main connecting plate, a first buckle assembly, a second buckle assembly, an angle adjustment mechanism, and a fixing device; the main connecting plate has a rectangular plate structure, with a first connecting end and a second connecting end at each end; the first buckle assembly is fixedly disposed at the first connecting end of the main connecting plate, and includes an upper jaw and a lower jaw, which are respectively fixed to the upper and lower surfaces of the main connecting plate, and both the upper and lower jaws have an arc-shaped structure with their openings facing opposite directions; the second buckle assembly is connected to the second connecting end of the main connecting plate through the angle adjustment mechanism, and includes a rotating body and a locking part, the rotating body being rotatably connected to the second connecting end of the main connecting plate through the angle adjustment mechanism; the locking part is fixedly disposed at the outer end of the rotating body, and the locking part has a barb-shaped structure; the fixing device includes a fastening bolt and a locking nut, the fastening bolt passing through an elongated through hole in the main connecting plate and an arc-shaped groove on the rotating body, and being locked and fixed to the rotating body by the locking nut.

[0007] The technical advantages of the adjustable-angle drainage ditch module connection buckle provided by this utility model are as follows: By setting a main connecting plate, a first buckle component, a second buckle component, an angle adjustment mechanism, and a fixing device, a complete drainage ditch module connection system is formed. The first buckle component is fixed to ensure a stable and reliable connection. The second buckle component is adjustable in angle through the angle adjustment mechanism, which can adapt to the connection needs of drainage ditch modules in different terrain environments. This solves the limitation of traditional drainage ditch modules that can only be connected in a straight line. The fixing device ensures that the adjusted angle is stable and does not deform, thus improving the adaptability and flexibility of the drainage system.

[0008] Based on the above technical solution, the adjustable-angle drainage ditch module connecting buckle of this utility model can be further improved as follows:

[0009] The angle adjustment mechanism includes a central shaft, a limiting block, and an elastic washer. One end of the central shaft is fixed to the center of the second connecting end of the main connecting plate, and the other end is rotatably connected to the rotating body. The limiting block is fixed to the surface of the second connecting end of the main connecting plate, and the outer edge of the limiting block has an arc-shaped structure. The elastic washer is sleeved on the central shaft and located between the main connecting plate and the rotating body to provide friction to maintain the angular position of the rotating body.

[0010] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the angle adjustment mechanism composed of the central shaft, the limiting block and the elastic washer realizes the smooth rotation of the rotating body relative to the main body connecting plate. The limiting block provides rotation guidance and the elastic washer increases friction to ensure that the position can be maintained after the angle is adjusted, avoiding angle changes due to external forces during use. At the same time, it provides operational comfort and precise control during the angle adjustment process.

[0011] Furthermore, the inner surface of the rotating body is provided with an arc-shaped groove that matches the outer edge of the limiting block. The curvature of the arc-shaped groove is the same as the curvature of the arc-shaped edge of the limiting block, so that the rotating body slides along the arc-shaped edge of the limiting block when rotating. The two ends of the limiting block are respectively provided with a first limiting protrusion and a second limiting protrusion, which are used to limit the maximum rotation angle range of the rotating body. The included angle between the first limiting protrusion and the second limiting protrusion is 90 degrees.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the arc-shaped groove is matched with the outer edge of the limiting block, so that the rotating body slides along the arc-shaped edge of the limiting block, providing a rotational guidance function. The limiting protrusions at both ends can limit the maximum rotation angle range of the rotating body, avoiding excessive rotation and structural damage. Furthermore, the maximum rotation angle of 90 degrees meets the corner requirements of most drainage systems, enabling the drainage ditch module to achieve right-angle turns or connections at any small angle.

[0013] Furthermore, the second connecting end of the main connecting plate is provided with a scale mark, and the edge of the rotating body is provided with an indicator mark. The indicator mark and the scale mark are used together to indicate the current angular position of the rotating body. The scale mark is evenly distributed along an arc, and the angular interval between adjacent scale marks is 5 degrees.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting scale marks at the second connection end of the main connecting plate and setting indicator marks on the edge of the rotating body, the visual control of angle adjustment is realized, so that the operator can clearly understand the current angle value being adjusted. The 5-degree scale interval provides sufficient precision to ensure the accuracy and consistency of angle adjustment, which facilitates the accurate adjustment of the connection angle of the drainage ditch module according to the design requirements during construction, thereby improving construction efficiency.

[0015] Furthermore, the inner surfaces of the upper and lower claws are provided with anti-slip textures, which are arranged in a herringbone pattern to increase the friction between the claw and the drainage ditch module; the inner surface of the latching part is also provided with the same anti-slip texture structure, and the depth of the anti-slip texture is 2 mm to 5 mm.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: Herringbone anti-slip texture is set on the inner surface of the upper claw, lower claw and the locking part, which significantly increases the friction between the upper claw and the drainage module, preventing slippage or detachment due to vibration or external force during use. The texture depth of 2 mm to 5 mm can ensure sufficient friction without causing excessive damage to the surface of the drainage module, thus improving the stability and safety of the connection.

[0017] Furthermore, the two sides of the main connecting plate are provided with reinforcing ribs. The reinforcing ribs extend along the length of the main connecting plate. The cross-section of the reinforcing ribs is triangular. The height of the reinforcing ribs gradually decreases from the middle of the main connecting plate to both ends. The height at the middle is twice the thickness of the main connecting plate, and the height at both ends is the same as the thickness of the main connecting plate.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: Triangular cross-section reinforcing ribs are set on both sides of the main connecting plate, and the height of the ribs gradually decreases from the middle to both ends, which significantly improves the bending strength and rigidity of the main connecting plate and prevents deformation when bearing load. In particular, the design that the height in the middle is twice the thickness of the main connecting plate can provide the maximum structural support while ensuring material economy and extending the service life of the buckle.

[0019] Furthermore, the main connecting plate, the first buckle assembly, and the second buckle assembly are all made of high-strength engineering plastics, which have the characteristics of corrosion resistance and aging resistance.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the main connecting plate, the first buckle assembly and the second buckle assembly are made of high-strength engineering plastics, which make full use of the corrosion resistance and anti-aging properties of such materials, so that the buckles can be used for a long time in humid and corrosive environments without being easily degraded. At the same time, the appropriate elasticity of engineering plastics also provides a certain buffering effect, increasing the overall elasticity and adaptability of the drainage system and reducing the stress concentration of the connection caused by factors such as ground settlement.

[0021] Furthermore, the outer surface of the rotating body is provided with a plurality of annular protrusions, which are evenly distributed along the circumference of the rotating body, and the height of the annular protrusions is 3 mm to 5 mm.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: multiple annular protrusions are set on the outer surface of the rotating body and evenly distributed along the circumference, which increases the surface roughness of the rotating body, provides a better feel and grip, and allows the operator to apply force evenly when adjusting the angle, avoiding slippage. The protrusion height of 3 mm to 5 mm can ensure sufficient friction without affecting the overall aesthetics or causing scratches to surrounding objects, thus optimizing the user experience.

[0023] Furthermore, the cross-section of the snap-fit ​​part is trapezoidal, with the width of the upper base being smaller than the width of the lower base, and the height of the trapezoid being 1.5 times the width of the snap-fit ​​part.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the cross-section of the snap-fit ​​part is designed as a trapezoidal structure, and the width of the upper base is smaller than the width of the lower base, forming an inwardly contracting wedge design, which makes it easy to insert the snap-fit ​​into the slot of the drainage ditch module, while generating greater resistance when pulling it out, thus achieving a one-way locking effect. The design of the trapezoidal height being 1.5 times the width ensures sufficient strength and toughness, preventing breakage due to external forces during use.

[0025] Furthermore, the arc length of the arc groove is one-third of the circumference of the rotating body, and the width of the arc groove is 2 to 4 millimeters larger than the diameter of the fastening bolt, so as to allow the fastening bolt to move within the arc groove to adjust the angle of the rotating body.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the arc length of the arc groove is designed to be one-third of the circumference of the rotating body, providing a sufficient range of angle adjustment. The design of the groove width being 2 to 4 millimeters larger than the diameter of the fastening bolt provides an appropriate gap for the fastening bolt to move within the arc groove, making it easy for the operator to smoothly adjust the angle of the rotating body. At the same time, it ensures the stability after locking, prevents loosening due to excessive gap, and improves the reliability and service life of the overall connection.

[0027] Compared with the prior art, the advantages of the adjustable-angle drainage ditch module connecting buckle provided by this utility model are:

[0028] This utility model provides an adjustable-angle drainage ditch module connecting buckle. Through the design of the main connecting plate and the rotatably connected second buckle assembly, it achieves continuous angle adjustment from 0 to 90 degrees, meeting the drainage ditch connection needs under different terrain conditions. A locking mechanism ensures the adjusted angle remains stable and is not easily loosened even under external force. The anti-slip texture and reinforcing ribs effectively improve connection strength and stability, enabling it to withstand greater lateral pressure and stress caused by temperature changes. The buckle is made of high-strength engineering plastic with excellent corrosion resistance, maintaining stable performance in humid environments for a long time. The trapezoidal snap-fit ​​design makes the connection tighter, easy to assemble and disassemble but not prone to falling off on its own. The annular protrusion on the outer surface provides a good operating feel, facilitating on-site construction, installation, and adjustment. The design of scale markings and indicator marks makes angle adjustment more intuitive and precise, effectively improving construction efficiency and connection accuracy. This utility model has a simple structure, low manufacturing cost, and long service life, significantly improving the flexibility, adaptability, and reliability of drainage systems.

[0045] The following is a specific embodiment of this utility model: The adjustable-angle drainage ditch module connecting buckle of this embodiment mainly includes five parts: a main connecting plate, a first buckle assembly, a second buckle assembly, an angle adjustment mechanism, and a fixing device. The main connecting plate is made of polyamide-modified nylon material, with a thickness of 8 mm, a length of 200 mm, and a width of 60 mm, forming a rectangular plate structure. The main connecting plate has a first connecting end and a second connecting end at each end. The width of the first connecting end is slightly larger than that of the second connecting end, forming a slightly trapezoidal appearance. This design makes the stress distribution more uniform. Reinforcing ribs are provided on both sides of the main connecting plate. The reinforcing ribs are integrally formed using the same material as the main connecting plate, with a triangular cross-section. The base width is 8 mm, the middle height is 16 mm, and it gradually decreases to 8 mm towards both ends, forming a streamlined appearance while improving structural strength. The first buckle assembly is fixed to the first connecting end of the main connecting plate and includes an upper clip and a lower clip. Both are made of the same material as the main connecting plate, but with 5% glass fiber reinforcement added, improving toughness and strength. Both the upper and lower jaws are arc-shaped with a radius of 15 mm and an arc length two-thirds the width of the main connecting plate. Their opening directions are opposite, forming a clamping structure. The inner surface of the jaws features a 3 mm deep herringbone anti-slip pattern with a 45-degree angle and a 2 mm spacing, significantly increasing contact friction with the drainage module. The second latch assembly is connected to the second connecting end of the main connecting plate via an angle adjustment mechanism, primarily consisting of a rotating body and a latching part. The rotating body is disc-shaped, 70 mm in diameter and 10 mm thick, made of polyamide reinforced with 10% glass fiber, providing excellent strength and durability. The outer surface of the rotating body is surrounded by eight equidistant annular protrusions, each 4 mm high and 6 mm wide, providing a good tactile feel during operation. The latching part is fixed to the outer end of the rotating body, featuring a hook-shaped structure with a trapezoidal cross-section, an upper base width of 8 mm, a lower base width of 12 mm, and a height of 15 mm. The inner surface of the locking part also features the same anti-slip texture as the upper and lower locking claws. The angle adjustment mechanism includes a central shaft, a limiting block, and an elastic washer. The central shaft is made of stainless steel, with a diameter of 10 mm and a length of 25 mm. One end is fixed to the center of the second connecting end of the main body connecting plate via an interference fit, and the other end is connected to the rotating body via a bearing. The limiting block is made of the same material as the main body connecting plate, is fan-shaped, and is fixed to the surface of the second connecting end of the main body connecting plate. Its outer edge is an arc with a radius of 25 mm. The limiting block has a first limiting protrusion and a second limiting protrusion with a height of 5 mm at both ends, and the included angle between the two is 90 degrees, limiting the maximum rotation range of the rotating body. The inner surface of the rotating body has an arc-shaped groove that matches the outer edge of the limiting block, with a depth of 5 mm and a width of 10 mm.The elastic washer is made of neoprene rubber, 2 mm thick, with an inner diameter of 10 mm and an outer diameter of 30 mm. It is fitted onto the central shaft between the main connecting plate and the rotating body. The fixing device includes fastening bolts and locking nuts, both made of 304 stainless steel. The fastening bolts are 8 mm in diameter and 40 mm long, passing through a 30 mm long, 10 mm wide elongated through-hole on the main connecting plate and an arc-shaped groove on the rotating body with an arc length one-third of the rotating body's circumference and a width of 12 mm. The locking nuts are M8 size and have nylon anti-loosening rings to ensure they will not loosen over long-term use. The second connecting end of the main connecting plate is engraved with angle markings, ranging from 0 to 90 degrees, with 5-degree intervals, a line depth of 0.5 mm, and a width of 0.5 mm, making them clear and easy to read. Indicating arrows are located on the edge of the rotating body as indicator marks, used in conjunction with the scale markings. In use, this invention can adapt to any angle connection within the range of 0 to 90 degrees, meeting the design requirements of most drainage systems. By rotating the anti-slip texture on the main body, the operator can easily adjust the angle, while the combination of scale markings and indicator marks ensures precise and controllable adjustment. After adjustment, tightening the locking nut secures the angle, preventing loosening even after long-term use in harsh environments. The design of this invention fully considers the actual operating conditions of drainage systems, particularly the impact of uneven ground and temperature changes on connection stability. Through structural optimization and material selection, it provides a reliable and easy-to-operate solution.

[0046] Specifically, the principle of this utility model is as follows: Based on the optimization of the connector structure and the rational utilization of material properties, this utility model designs a drainage ditch module connecting buckle that can freely adjust the connection angle within a fixed range. Its core principle is to divide the connection structure into two parts: a fixed end and an adjustable end. The fixed end is firmly connected to a drainage ditch module via upper and lower jaws, while the adjustable end achieves angle adjustment through a rotating body supported by a central shaft. The relative position between the rotating body and the main connecting plate can be steplessly adjusted via an arc-shaped groove and fastening bolts, and is fixed by a locking nut after adjustment. To ensure accurate angle adjustment and reliable locking, a limit block and an indicating system are designed. The former provides physical limits to ensure the angle range is within a safe range, while the latter provides visual reference to ensure adjustment accuracy. Simultaneously, through material selection and surface treatment, the problem of traditional connectors being prone to corrosion and aging in humid environments is solved. The trapezoidal cross-section of the snap-fit ​​part utilizes the wedge principle to make the connection more robust, while the surface anti-slip texture increases friction to resist the effects of vibration and lateral forces. The design of the triangular reinforcing ribs is based on stress distribution laws, maximizing structural strength and rigidity while using materials economically.

[0047] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
