Description

Technical Field

[0001] The present invention relates to the technical field of assembled landscape engineering equipment, in particular to a quick connection device for modular landscape components. Background Art

[0002] Modular landscape components are prefabricated units that are constructed using standardized design, factory production, and on-site assembly. This design approach is efficient, flexible, and sustainable, and is widely used in urban public spaces, architectural landscapes, and ecological restoration. Modular landscape components come in a variety of types, including: paving modules: permeable bricks, stone / wood-plastic composite panels, and removable platforms;

[0003] Fences / retaining walls: precast concrete blocks; Seats / flower boxes: multifunctional modular furniture that combines rest and greening functions; Lighting modules: embedded floor lights, solar lighting and paving systems; Greening modules: vertical green wall units, lawn grids, modular planting pools, etc.

[0004] Modular guardrails: Safety protection types include prefabricated anti-fall guardrails (height ≥ 1.1m) for waterside areas: rivers and pools, height difference boundaries: guardrails at the edges of steps, ramps, and roof gardens, and vehicle isolation: modular isolation barriers between motor vehicle lanes and pedestrian areas;

[0005] The decorative guidance type includes space division: movable flower box + guardrail combination, flexible separation of squares / green spaces, visual guidance: guardrail modules with embedded lighting or signs to guide pedestrian flow;

[0006] The ecological composite type includes vertical greening guardrails: guardrail modules with integrated planting troughs (such as climbing plant supports), and animal passages: special guardrail designs reserved for wild animal passages in ecological parks.

[0007] Among them, for modular guardrails, no matter what situation or function they are used in, their installation form needs to be modularly adapted according to the scene. For modular guardrails used in garden landscapes, since the landscape needs to be regularly revised and changed, such as changing the landscape features or local full planning, guardrails used for safety protection, decorative guidance, etc. need to be quickly connected or separated. Especially when connecting, due to different usage scenarios, they need to be stably and quickly connected at a certain angle according to the layout requirements. However, for existing landscape component modular guardrails, they have the defects of high connection difficulty when connecting or disassembling, and easy loosening when adjusting the angle of adjacent guardrails.

[0008] In view of the above problems, this technical solution designs a quick connection device for modular landscape components. Summary of the Invention

[0009] The object of the present invention is to provide a quick connection device for modular landscape components to solve the problems raised in the above background technology.

[0010] To achieve the above object, the present invention provides the following technical solutions:

[0011] The quick connection device of the modular landscape component includes a female connector and a male connector installed on the side walls of the columns at the end ends of the modular landscape guardrail. A connecting unit groove is opened on the columns corresponding to the roots of the female connector and the male connector. When two adjacent groups of modular landscape guardrails are connected horizontally, the female connector and the male connector adopt a two-stage installation and disassembly mode, that is, the first-stage force plug-in positioning, and the second-stage force plug-in separation. The female connector and the male connector are connected to the side facing the inside of the connecting unit groove with a swing connector. The end of the swing connector away from the female connector and the male connector is connected to the inner wall of the connecting unit groove through a rotation limiter. Under the control of the rotation limiter, the end of the swing connector is kept in the lateral limit position inside the connecting unit groove and rotates circumferentially. The swing connector is used to control the female connector and the male connector to swing relative to the rotation limiter, that is, after the female connector and the male connector are plugged and positioned, the modular landscape guardrails on both sides can be adjusted within a certain angle, that is, the protection layout angle of the modular landscape guardrail is adjusted;

[0012] Among them, the rotation limiter on one side of the male connector is away from the column in the direction of the female connector, and an axial movement channel with an open end is opened inside. A transverse movement member rotates inside the axial movement channel. The transverse movement member is manually controlled, and a thread passes through the middle of the rotation limiter. One end of the transverse movement member is rotationally connected to the end of the swing connector, and the other end extends to the opening of the axial movement channel. The transverse movement member is used to control the male connector to move toward the inside of the female connector to perform secondary force insertion and separation;

[0013] A set of fan-shaped gears extending to the outside of the connecting unit slot are fixedly installed in the middle of the bottom of each connecting unit slot through a fixing sleeve. The fan-shaped gears on both sides are meshed with each other when the female connector and the male connector are positioned at the first level of plugging. When the module landscape guardrails on both sides are adjusted in angle, the two sets of fan-shaped gears are relatively meshed and swung to improve the stability and balance of the module landscape guardrail when swinging. A swing bin with an arc structure is provided inside the corresponding column on the lower side of the connecting unit slot. The middle part of the swing bin is connected to a swing positioning plate through a swing shaft. The swing shaft moves upward and extends to the inside of the connecting unit slot and rotates to connect In the middle of the fixed sleeve, a locking piece is provided at the bottom of the swing shaft connected downwardly. The locking piece is used to limit the rotation of the swing shaft, that is, after the modular landscape guardrails on both sides are swung to the desired angle, the rotation of the swing shaft is limited by the locking piece, so as to keep the modular landscape guardrail stable after the angle is adjusted. The ends of the swing positioning plates on both sides are respectively installed with pins and sockets. When the two sets of sector gears are engaged, the pins are plugged into the pins and rotate simultaneously with the swing of the modular landscape guardrails on both sides, so as to further improve the stability of the placement position adjustment after the female connector and the male connector connect the modular landscape guardrails on both sides.

[0014] That is, when two sets of modular landscape guardrails are connected, the corresponding female connectors and male connectors are controlled to be close to each other, the male connector is inserted into the female connector until it is elastically positioned, and then with the cooperation of the rotation limiter, swing connector, fan gear, swing positioning plate, pin, jack and locking part, the modular landscape guardrails on both sides are adjusted to a stable placement angle.

[0015] Compared with the prior art, the present invention has the following advantages: through the two-stage plug-in mechanism: the first stage is elastic positioning and quick locking, and the second stage is double cone ring top opening and separation, which reduces the difficulty of disassembly and assembly;

[0016] The swing connector and sector gear set ensure stable guardrail adjustment, prevent loose connections, and achieve dynamic adjustment.

[0017] The double fixation of the pin-socket linkage and the lock nut enhances the structural stability after angle adjustment;

[0018] Modular adaptation: suitable for connecting various landscape components such as paving, guardrails, lighting, etc. to meet the dynamic layout requirements of garden landscapes. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0037] like Figure 1-Figure 4 、 Figure 7 As shown, the quick connection device of the modular landscape component includes a female connector 13 and a male connector 14 installed on the side walls of the end columns 11 at both ends of the modular landscape guardrail 10. The female connector 13 and the male connector 14 are provided with a connection unit groove 12 on the columns 11 corresponding to the roots of the female connector 13 and the male connector 14. When two adjacent groups of modular landscape guardrails 10 are connected horizontally, the female connector 13 and the male connector 14 adopt a two-stage installation and removal mode, that is, the first-level force plug-in positioning and the second-level force plug-in separation. The female connector 13 and the male connector 14 are connected to one side of the connection unit groove 12. A swing connection is provided. The end of the swing connector 15 away from the female connector 13 and the male connector 14 is connected to the inner wall of the connecting unit groove 12 through a rotation limiter. Under the control of the rotation limiter, the end of the swing connector 15 is kept in the connecting unit groove 12 for transverse movement and circumferential rotation. The swing connector 15 is used to control the female connector 13 and the male connector 14 to swing relative to the rotation limiter. That is, after the female connector 13 and the male connector 14 are plugged and positioned, the modular landscape guardrails 10 on both sides can be adjusted within a certain angle, that is, the protective arrangement angle of the modular landscape guardrail 10 is adjusted;

[0038] Among them, the rotation limiter on one side of the male connector 14 is away from the column 11 in the direction of the female connector 13, and an axial movement channel 21 with an open end is opened inside. A transverse movement member rotates inside the axial movement channel 21. The transverse movement member is manually controlled, and a thread passes through the middle of the rotation limiter. One end of the transverse movement member is rotationally connected to the end of the swing connector 15, and the other end extends to the opening of the axial movement channel 21. The transverse movement member is used to control the male connector 14 to move toward the inside of the female connector 13 to perform secondary force insertion and separation;

[0039] A group of fan-shaped gears 24 extending to the outside of the connecting unit slot 12 are fixedly installed on the middle part of the inner bottom of each group of connecting unit slots 12 through a fixing sleeve 26 (the center of the fan-shaped gear 24 is connected to the fixing sleeve 26, and the tooth groove of the fan-shaped gear 24 extends to the outside of the connecting unit slot 12). The fan-shaped gears 24 on both sides are engaged with each other when the female connector 13 and the male connector 14 are connected to the first-level plug-in positioning, so as to keep the two groups of fan-shaped gears 24 relative to each other when the module landscape guardrails 10 on both sides are adjusted in angle, so as to improve the stability and balance of the module landscape guardrail 10 when it swings. An arc-shaped swing bin 27 is provided inside the column 11 corresponding to the lower side of the connecting unit slot 12. The middle part of the swing bin 27 is connected to the swing positioning plate 31 through the swing shaft 25. The swing shaft 2 5 is movably extended upward to the inside of the connecting unit groove 12 and is rotatably connected to the middle part of the fixing sleeve 26. The bottom of the swing shaft 25 is connected downwardly to a locking member. The locking member is used to limit the rotation of the swing shaft 25. That is, after the modular landscape guardrails 10 on both sides are swung to the desired angle, the rotation of the swing shaft 25 is limited by the locking member, thereby maintaining the stability of the modular landscape guardrail 10 after the angle adjustment. The ends of the swing positioning plates 31 on both sides are respectively installed with latches 32 and sockets 33. When the two sets of sector gears 24 are engaged, the latches 32 are plugged into the latches 32 and rotate simultaneously with the swing of the modular landscape guardrails 10 on both sides, so as to further improve the stability of the placement position adjustment after the female connector 13 and the male connector 14 connect the modular landscape guardrails 10 on both sides.

[0040] That is, when two sets of modular landscape guardrails 10 are connected, the corresponding female connectors 13 and male connectors 14 are controlled to be close to each other, and the male connector 14 is inserted into the female connector 13 until it is elastically positioned. Then, with the cooperation of the rotation limiter, the swing connector 15, the sector gear 24, the swing positioning plate 31, the pin 32, the socket 33 and the locking member, the modular landscape guardrails 10 on both sides are adjusted to a stable placement angle.

[0041] In the embodiment of the present invention, the modular landscape guardrail 10 is configured as a prefabricated part, usually made of aluminum alloy, galvanized steel, recycled plastic, etc. The column 11 and the modular landscape guardrail 10 can be designed as an integrated molding, or can be designed to be fixedly installed at both ends of the modular landscape guardrail 10. At the same time, embedded parts or ground plug structures are provided at the bottom of the column 11 to ensure that the bottom of the modular landscape guardrail 10 is fixed to the ground of the landscape garden to be used after connection and adjustment, so that it can be fully arranged for protection.

[0042] The connecting unit slot 12 is set to a rectangular structure with an inner corner set to an arc shape, which is used to provide sufficient operating space for the female connector 13, the male connector 14, the swing connector 15 and the rotation limiter while ensuring its aesthetics;

[0043] A locking nut bin 28 with an external opening is provided in the inner wall of the column 11 corresponding to the locking piece. The locking piece includes a longitudinal positioning screw 29 connected to the bottom of the swing shaft 25. The longitudinal positioning screw 29 moves upward through the top of the locking nut bin 28 and is fixedly connected to the bottom of the swing shaft 25. At the same time, a locking nut 30 is threadedly connected to the longitudinal positioning screw 29 located inside the locking nut bin 28. The locking nut 30 is provided with corrugated strips on both sides that contact the inner top wall of the locking nut bin 28, which is used to increase the contact resistance with the inner top wall of the locking nut bin 28, so as to limit the rotation of the longitudinal positioning screw 29 by screwing the locking nut 30, thereby keeping the modular landscape guardrail 10 stable after the arrangement angle adjustment.

[0044] In one embodiment of the present invention, the rotation limiting member includes a rotation positioning shaft 16 connected to the end of the swing connection member 15, and a rotation limiting ring 17 is fixedly installed on the rotation positioning shaft 16. The inner wall of the connection unit groove 12 corresponding to the rotation limiting ring 17 is provided with a rotation limiting groove. The rotation limiting ring 17 is placed in the rotation limiting groove and rotates, thereby realizing an operating mode in which the end of the swing connection member 15 is placed in the connection unit groove 12 for lateral movement limitation and circumferential rotation.

[0045] The swing connection member 15 includes a U-shaped rotating frame I 150 and a U-shaped rotating frame II 151. The U-shaped rotating frame I 150 and the U-shaped rotating frame II 151 are cross-distributed on one side of the opening and are rotatably connected by a cross connecting rod 152. The female connector 13 and the male connector 14 are respectively fixedly connected to the side of the U-shaped rotating frame II 151 away from the U-shaped rotating frame I 150. When the rotating positioning shaft 16 rotates, it keeps the U-shaped rotating frame I 150 rotating synchronously with it, and then rotates on the cross connecting rod 15 2, the U-shaped rotating frame II 151 is controlled to rotate synchronously. At the same time, the cross distribution of the U-shaped rotating frame I 150 and the U-shaped rotating frame II 151 is utilized to keep the U-shaped rotating frame II 151 swinging relative to the U-shaped rotating frame I 150, so that when the modular landscape guardrails 10 on both sides are adjusted in angle, the female connector 13 and the male connector 14 are kept free to swing after being plugged and positioned under the connection control of the U-shaped rotating frame I 150 and the U-shaped rotating frame II 151.

[0046] like Figure 2 、 Figure 5 、 Figure 7 As shown, the female connector 13 includes an elastic positioning hole block 130 with a truncated cone structure. One side of the elastic positioning hole block 130 is fixedly connected to the side wall of the U-shaped rotating frame II 151 through a connecting block. The elastic positioning hole block 130 is provided with a plug-in channel in the axial center. A radial telescopic channel 131 is provided on one side of the plug-in channel. A group of radial telescopic rods 132 are elastically provided inside the radial telescopic channel 131. A right-angled triangular positioning block 135 is installed at one end of the radial telescopic rod 132 toward the plug-in channel. A set of spring limiting rings 133 are mounted on one side of the end of the telescopic rod 132 away from the right-angled triangular positioning block 135. The spring limiting ring 133 has a limiting ring groove 134 formed on the circumferential inner wall corresponding to the radial telescopic channel 131. The spring limiting ring 133 is placed in the limiting ring groove 134 to rotate and limit the radial position. At the same time, a set of sleeve springs 136 are mounted between the right-angled triangular positioning block 135 and the spring limiting ring 133. When the sleeve springs 136 are in a free state, they control the right-angled triangular positioning block 135 to extend into the interior of the insertion channel.

[0047] The male connector 14 includes a tapered locating pin 140, and the side diameter of the tapered locating pin 140 away from the cone angle is matched with the clearance of the insertion channel, that is, after the tapered locating pin 140 moves to the inside of the insertion channel, its inclined surface is used to gradually apply an outward radial thrust to the right-angled triangle positioning block 135 until the side of the tapered locating pin 140 moves to the side of the right-angled surface of the right-angled triangle positioning block 135. At this time, the rebound force of the sleeve spring 136 is used to fix the position of the tapered locating pin 140 to achieve the first-level plug-in positioning. At this time, the external pin 32 is plugged into the socket 33, and the sector gears 24 on both sides are engaged to prevent the modular landscape guardrails 10 on both sides from continuing to approach, that is, to prevent the tapered locating pin 140 from continuing to move toward the insertion channel. The tapered locating pin 140 rotates toward the U-shaped One side of the rotating frame II 151 is fixedly connected by a ring sliding rod 142, and a double cone ring 141 is slidably sleeved on the ring sliding rod 142. The middle cross-section of the double cone ring 141 is the same as the side of the tapered positioning pin 140. After achieving the first-level plug-in positioning, the tapered positioning pin 140 is continued to be pushed toward the plug-in channel, and the double cone ring 141 is controlled to move gradually to contact the right-angled triangle positioning block 135 and push it to move radially upward until the right-angled triangle positioning block 135 moves to the side of the double cone ring 141 away from the tapered positioning pin 140. At this time, by pulling the two sides of the modular landscape guardrail 10 to separate from each other, the right-angled triangle positioning block 135 passes along the edge of the tapered positioning pin 140 and the double cone ring 141, thereby losing resistance and achieving the second-level force separation.

[0048] like Figure 2 、 Figure 6 、 Figure 7 As shown, the lateral moving member includes an inner screw hole 22 provided at the center of the rotation positioning shaft 16, the inner screw hole 22 is threadedly connected with an axial moving screw 18, the axial moving screw 18 is installed with a guide rod at the end facing the U-shaped rotating frame I 150, the end of the guide rod is connected with a T-shaped rotating block 34, the T-shaped rotating block 34 is provided with a T-shaped rotating slot 35 inside the U-shaped rotating frame I 150 corresponding to the T-shaped rotating block 34, the T-shaped rotating block 34 is placed in the T-shaped rotating slot 35 for rotation limit connection, the end of the axial moving screw 18 away from the guide rod is connected with a connecting rod 19 placed inside the axial moving channel 21, the outer end of the connecting rod 19 is installed with a turning handle 20, and the turning handle 20 is manually rotated to control the connecting rod 19 to drive the axial moving screw 18 to move laterally along the inner thread of the inner screw hole 22, and then control the lateral movement of the U-shaped rotating frame I 150, thereby driving the tapered positioning pin 140 on one side thereof to continue to move toward the insertion channel;

[0049] It should be noted that when the modular landscape guardrails 10 on both sides are disassembled, if the angle between them is too large, when the tapered positioning pins 140 are controlled to move inside the plug-in channel by the lateral moving member, since the U-shaped rotating frame I 150 and the U-shaped rotating frame II 151 are in a state of tilted swing connection, when the U-shaped rotating frame II 151 is controlled to move by pushing the U-shaped rotating frame I 150, there is a situation where the moving distance of the U-shaped rotating frame II 151 is insufficient. In this case, the angle between the modular landscape guardrails 10 on both sides is enlarged, that is, a state in which the two sides are parallel is formed. Since the bottom column 11 needs to be separated from the ground in advance when the modular landscape guardrails 10 are disassembled, the angle of the modular landscape guardrails 10 on both sides is adjusted first before separation, and the time and operation steps of the disassembly are not affected.

[0050] It should be noted that after the tapered positioning pin 140 is controlled to be inserted into the insertion channel by rotating the lateral moving member, it is necessary to reset the tapered positioning pin 140 before the next insertion after separation.

[0051] As a preferred embodiment of the present invention, a handle movement slot 23 having a larger diameter than the axial movement slot 21 is defined at the end of the handle 20 corresponding to the axial movement channel 21. The handle 20 is positioned within the handle movement slot 23 for rotation and transverse movement, ensuring that the handle movement slot 23 provides space for manual operation while maintaining the area of ​​the modular landscape guardrail 10 outside the handle movement slot 23 open. Operating the handle 20 within the handle movement slot 23 prevents it from moving outside the handle movement slot 23, which would affect the aesthetics.

[0052] As a preferred embodiment of the present invention, Figure 8-Figure 9 As shown, after the modular landscape guardrails 10 on both sides are connected by this connecting device, the distance between the columns 11 is effectively reduced, and the interval is set within the safety protection range. The specific size can refer to the protection standards in the existing garden landscape component guardrails. It will not be repeated here, nor will it be limited.

[0053] The working principle of the present invention is: in the idle space of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connections between the electrical components are completed in sequence. The detailed connection means are well known in the art. The following mainly introduces the working principle and process, and does not explain the electrical control.

[0054] 1. Connection phase

[0055] Step 1.1 Initial positioning

[0056] Push the adjacent module landscape guardrail 10 so that the tapered positioning pin 140 of the male connector 14 is aligned with the elastic positioning hole block 130 of the female connector 13 .

[0057] Step 1.2: First-level elastic locking

[0058] When the tapered positioning pin 140 is inserted, its tapered surface squeezes the triangular positioning block 135, forcing the radial telescopic rod 132 to retreat along the radial telescopic channel 131;

[0059] The sleeve spring 136 is compressed until the groove on the side of the tapered positioning pin 140 moves to the position of the triangular positioning block 135;

[0060] The sleeve spring 136 releases its elastic force, pushing the triangular positioning block 135 into the groove, completing the first-level mechanical locking.

[0061] 2. Angle adjustment stage

[0062] Step 2.1 Free Swing

[0063] The rotating guardrail 10 drives the swing connecting piece 15 to move:

[0064] The U-shaped rotating frames I 150 and II 151 rotate crosswise via a cross connecting rod 152;

[0065] The linked rotation positioning shaft 16 deflects in the connection unit groove 12 and is constrained from lateral displacement by the rotation limiting ring 17 .

[0066] Step 2.2 Gear Synchronous Positioning

[0067] The sector gears 24 on both sides of the columns are meshed with the swing transmission to limit the rotation angle and prevent the angle from exceeding the limit;

[0068] The swing shaft 25 synchronously drives the swing positioning plate 31 to rotate, so that the latch 32 is automatically inserted into the socket 33 of the adjacent component.

[0069] Step 2.3 Angle Fixation

[0070] Tighten the lock nut 30, and the corrugated strips on its contact surface increase the friction force, pressing the longitudinal positioning screw 29 into the lock nut chamber 28;

[0071] The swing shaft 25 is locked to achieve irreversible angle fixation.

[0072] 3. Separation phase

[0073] Step 3.1 Triggering secondary separation

[0074] The operating handle 20 rotates in the handle moving groove 23, driving the axial moving screw 18 to advance along the axial moving channel 21;

[0075] The screw slides in the T-shaped rotating slot 35 via the T-shaped rotating block 34, pushing the rotating positioning shaft 16 to move laterally.

[0076] Step 3.2 Release the mechanical lock

[0077] The rotating positioning shaft 16 pushes the double cone ring 141 forward along the ring sliding rod 142;

[0078] The conical surface of the double-conical ring 141 presses against the inclined surface of the triangular positioning block 135, forcing it to exit the groove of the conical positioning pin 140;

[0079] The sleeve spring 136 is compressed for the second time, releasing the primary locking.

[0080] Step 3.3 Component separation

[0081] Pull the guardrail in the opposite direction, and the tapered positioning pin 140 is pulled out from the elastic positioning hole block 130;

[0082] The sector gear 24 is disengaged, and the latch 32 exits the socket 33, completing the separation.

[0083] It should be understood that in the present application, the rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slipping or wear, and their exteriors are all provided with corresponding protective shells. However, in the drawings of the present application, in order to clearly indicate the connection status of the moving parts, they are not shown. It can also be understood that each component in the present application is made of metal or plastic material with adaptable strength in the field to which it belongs to ensure that its structural rigidity meets actual needs.

[0084] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
