Technical Field

[0001] This utility model relates to the field of fiberglass component installation technology, specifically to a fiberglass column connector with a quick installation structure. Background Technology

[0002] Existing fiberglass column connectors generally use bolt fastening, requiring multiple people and power tools for installation, which has the following drawbacks:

[0003] 1. Low installation efficiency; bolt tightening requires repeated alignment of the holes, which is time-consuming.

[0004] 2. In outdoor environments, threaded connections are prone to corrosion, resulting in high maintenance costs.

[0005] 3. The installation status cannot be visually confirmed, posing a safety hazard.

[0006] Therefore, there is an urgent need for a structural improvement solution that can achieve rapid and stable installation without tools, and has anti-loosening and visualization functions. Utility Model Content

[0007] The purpose of this utility model is to provide a fiberglass column connector with a quick-installation structure to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A fiberglass column connector with a quick-installation structure includes:

[0010] The base is fixed to the outer side of the end of the fiberglass column and serves as the mounting base for each functional component.

[0011] The guide and positioning mechanism is located at the front end of the central inner cavity of the base. It includes a tapered guide sleeve arranged coaxially with the axis of the fiberglass column and positioning pins distributed at equal angles along the circumferential direction of the inner wall. During the insertion process, it restricts the radial displacement of the insertion parts and automatically corrects the position.

[0012] The quick-locking mechanism is located behind the guide positioning mechanism. It includes a rotating buckle hinged to the base via a rotating shaft, a handle fixed to the outer end of the rotating buckle, an eccentric cam set between the rotating buckle and the locking plate, and a locking plate that presses the outer wall of the fiberglass column radially. When the handle is rotated, the eccentric cam drives the locking plate to move radially and press the outer wall of the fiberglass column.

[0013] The anti-loosening structure is set on the force path of the rotating buckle and the locking plate, including a disc spring washer and a sealing ring located at the contact point between the outer edge of the base and the outer wall of the fiberglass column. In the locked state, it provides continuous pre-tightening force and forms a waterproof sealing interface.

[0014] The visual indicator structure is located at the outer end of the rotating buckle. It includes an indicator rod arranged along the axial slide and a two-color identification ring sleeved on its outer end. When the handle is rotated to the locking position, the indicator rod is pushed out by the linkage boss on the eccentric cam, and the two-color identification ring rotates synchronously until the green sector is aligned with the operator's direction, indicating that the locking is complete.

[0015] Furthermore, the tapered guide sleeve has a cone angle of 30° to 45° and an effective length of 10 to 18 mm; the positioning pins are distributed at equal angles along the circumference, with a radial insertion amount of 0.8 to 1.5 mm.

[0016] Furthermore, the rotating buckle is hinged to the base via a pivot with a diameter of 6 to 8 mm, and the handle is 50 to 80 mm long, capable of driving the eccentric cam to rotate within a 90° rotation range, with an eccentricity of 1.0 to 2.0 mm and a radius of 12 to 18 mm.

[0017] Furthermore, the pre-compression of the disc spring washer is 0.2 to 0.5 mm, and the pre-tightening force is 200 to 600 N; the compression rate of the sealing ring in the locked state is 15% to 25%, forming a continuous sealing interface on the contact surface, with a contact pressure of not less than 0.3 MPa, and a waterproof rating of IP65.

[0018] Furthermore, the pop-out stroke of the indicator rod is 4 mm. The two-color marking ring and the indicator rod are linked by a keyway. When the indicator rod is pushed out, the two-color marking ring rotates 90° synchronously, with the green sector facing the operator. When the handle is rotated in the opposite direction, the indicator rod retracts, and the red sector of the two-color marking ring faces the operator.

[0019] Furthermore, the outer wall of the end of the fiberglass column is provided with an annular limiting groove, the groove width is 2.0 to 3.5 mm, the groove depth is 0.8 to 1.5 mm, and the distance from the end face is 5 to 8 mm. When the locking plate is pressed to the end point, it fits against the side wall of the limiting groove to form a double limiting in the radial and axial directions.

[0020] Furthermore, the base is connected to the end of the fiberglass column by 4 to 6 M6 or M8 bolts with a tightening torque of 10 to 18 Nm, while an epoxy structural adhesive with a thickness of 0.2 to 0.4 mm is applied to the flange contact surface.

[0021] Furthermore, the outer surface of the base and the inner wall of the bolt holes are sprayed with an epoxy resin anti-corrosion coating with a thickness of 0.2 to 0.3 mm, which is cured at 160°C for 30 minutes to form a continuous and dense protective layer.

[0022] Furthermore, the guiding and positioning mechanism, the quick-locking mechanism, and the anti-loosening structure are all made of stainless steel or engineering plastics, the base is made of fiberglass, and the sealing ring is made of EPDM material with a Shore hardness of 60±5.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This fiberglass column connector with a quick-installation structure adopts a guide positioning mechanism and a transmission combination of rotary buckle + eccentric cam + locking plate, which realizes rapid assembly under single-person and tool-free conditions, significantly improving installation efficiency and avoiding the problems of traditional bolt tightening requiring multiple people and taking a long time.

[0025] 2. This fiberglass column connector with a quick-installation structure, through the elastic pre-tightening of the disc spring washer and the compression sealing design of the sealing ring, ensures that the locking structure can maintain stable clamping force and IP65 waterproof performance under long-term stress, vibration and rain conditions, thus ensuring the reliability and safety of outdoor use.

[0034] 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.

[0035] like Figures 1 to 7 As shown, this fiberglass column connector with a quick-installation structure mainly consists of a base 1, a fiberglass column 2, a guide and positioning mechanism 3, a quick-locking mechanism 4, an anti-loosening structure 5, a visual indicator structure 6, bolts 7, adhesive 8, an anti-corrosion coating 9, and an annular limiting groove 10. During installation, the entire system uses the base 1 as the main load-bearing body, integrating all functional components to achieve functions such as quick insertion, locking, waterproof sealing, and visual display of the locking status.

[0036] In a typical design, the base 1 is made of fiberglass. The recommended flange outer diameter is 100 mm, which can be adjusted from 80 to 140 mm for different fiberglass column specifications. The recommended flange thickness is 8 mm, with an allowable range of 6 to 10 mm. The height of the central cylindrical section is 15 mm, but can actually vary from 12 to 20 mm to accommodate different space conditions at the ends of the fiberglass columns. Four to six bolt holes are drilled circumferentially along the outer edge of the base. M6 or M8 bolts are recommended, with a tightening torque of 10 to 18 Nm. A 0.2 to 0.4 mm thick layer of epoxy structural adhesive 8 is applied around the bolt holes, which can be cured at room temperature for 24 hours or at 60°C for 2 hours. This ensures a reliable surface contact connection between the base and the ends of the fiberglass columns, reducing the risk of loosening due to vibration or impact. After sandblasting, the outer surface of the base and the inner wall of the bolt holes are uniformly coated with an epoxy resin powder coating 9 with a thickness of 0.2 to 0.3 mm, and then heated and cured at 160°C for 30 minutes to form a continuous and dense protective layer on the surface, preventing rainwater and corrosive media in the air from penetrating and ensuring that the connectors can operate stably for a long time in outdoor high humidity and high salt spray environments.

[0037] To ensure automatic alignment of the connector during installation, a guide positioning mechanism 3 is installed at the front end of the central inner cavity of the base. This mechanism consists of a tapered guide sleeve 31 and several positioning pins 32. The guide sleeve 31 is coaxial with the fiberglass column axis, with its small end facing the insertion direction. A tapered angle of 35° is recommended, with an allowable range of 30° to 45°. Its effective length is 15 mm, with an allowable range of 10 to 18 mm. It automatically guides the connector during insertion. The positioning pins 32 are evenly distributed along the circumference, with four recommended and four to six allowed. Their radial insertion depth is approximately 1 mm, adjustable within the range of 0.8 to 1.5 mm. Adhering to the H7 / g6 tolerance standard, this ensures that the radial deviation does not exceed 0.3 mm after insertion, providing a stable positioning reference for subsequent locking.

[0038] A quick-locking mechanism 4 is arranged behind the guide positioning mechanism. It includes a rotary latch 41, an eccentric cam 42, a handle 43, and a locking plate 44. The rotary latch 41 is hinged to the base 1 via a rotating shaft parallel to the axis of the fiberglass column. The diameter of the rotating shaft is 6 mm, adjustable within the range of 6 to 8 mm. Both ends are limited by snap rings to the base, ensuring flexible and reliable rotation. The handle 43 is fixed to the outer end of the rotary latch. Its length is recommended to be 60 mm, adjustable between 50 and 80 mm, ensuring one-handed operation. The eccentric cam 42 is located between the rotary latch and the locking plate. The recommended eccentricity is 1.5 mm, with an allowable range of 1 to 2 mm. The radius is 15 mm, with an allowable range of 12 to 18 mm. When the handle is rotated 90°, the eccentric cam drives the locking plate to move radially by 1.5 mm, causing its inner arc surface to press against the outer wall of the fiberglass column and fit against the side wall of the annular limiting groove 10. The clamping force is calculated using the formula F≈η·T / (e+μRc), where η is taken as 0.85 and the coefficient of friction μ is taken as 0.15. When a torque of 15 Nm is applied to the handle, the clamping force on the contact surface can reach more than 1 kN, which is sufficient to ensure a secure lock.

[0039] An anti-loosening structure 5, including a disc spring washer 51 and a sealing ring 52, is installed on the locking force transmission path. The spring washer 51 has a single-piece pre-compression of 0.3 mm, which can be adjusted within the range of 0.2 to 0.5 mm. The pre-tightening force is 400 N, with an allowable range of 200 to 600 N, which can maintain the locking force without decreasing under temperature changes or long-term vibration conditions. The sealing ring 52 is located on the contact surface between the outer edge of the base and the outer wall of the fiberglass column. It is recommended to use EPDM material with a Shore hardness of 60±5, with a compression rate controlled at 20%, allowing a range of 15% to 25%. During locking, a continuous closed-line contact is formed on the contact surface, with a contact pressure of over 0.3 MPa, so that the entire device can achieve an IP65 waterproof rating after locking.

[0040] A visual indicator structure 6 is integrated into the outer end of the rotary buckle, consisting of an indicator rod 61 and a two-color identification ring 62. The indicator rod 61 is arranged along the axial slide rail and has a compression spring preloaded inside. Its end contacts the linkage boss on the eccentric cam 42. When the handle 43 is rotated to the locked position, the boss pushes the indicator rod 61 against the spring force and ejects it by 4 mm. At the same time, it drives the two-color identification ring 62, which is sleeved on the outer end, to rotate 90° synchronously, so that the green sector faces directly in front of the operator, intuitively displaying the "locking complete" status. When the handle is rotated in the opposite direction, the spring returns, the indicator rod resets, and the identification ring rotates back to the red sector facing forward, indicating that the connection is loosened.

[0041] An annular limiting groove 10 is formed on the outer wall of the fiberglass column end, 6 mm from the end face. The groove is 2.5 mm wide, with an allowable range of 2.0 to 3.5 mm, and 1 mm deep, with an allowable range of 0.8 to 1.5 mm. When the locking plate 44 is radially pressed under the drive of the eccentric cam, its inner arc edge fits against the side wall of the limiting groove 10, forming a double limit in both the radial and axial directions, preventing over-insertion or axial slippage after long-term use.

[0042] During installation, the operator first secures the base 1 to the end of the fiberglass column using bolts and adhesive. When the connector is inserted, the tapered guide sleeve 31 and the positioning pin 32 automatically complete the positional correction. Then, rotating the handle 43 causes the eccentric cam 42 to drive the locking plate 44 to radially press against the outer wall of the fiberglass column. The spring washer 51 provides continuous preload, the sealing ring 52 forms a waterproof barrier, and the indicator rod 61 pops out and displays the green sector. The entire process requires no tools and can be completed by a single person. Disassembly is simple: rotating the handle in the opposite direction returns the indicator rod 61 to the red area, the locking plate 44 loosens, and the connector can be pulled out.

[0043] For different environments, the guide sleeve 31 can be made of PA66+GF engineering plastic with PTFE self-lubricating layer, the anti-corrosion coating 9 can be upgraded to a two-layer system of epoxy primer and polyurethane topcoat with a total thickness of 220 to 320 micrometers, the sealing ring 52 can be made of fluororubber material to improve high temperature resistance, and the spring washer 51 can also be replaced with wave spring. These improvements will not affect the basic structure and function of this utility model.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
