Technical Field
[0001] This utility model belongs to the field of fiberglass sleeve technology, specifically a fiberglass sleeve with strong protective properties. Background Technology
[0002] Fiberglass reinforced plastic (FRP) conduit is a composite pipe made of glass fiber as reinforcement and synthetic resin as matrix through a specific process. It is corrosion-resistant, has good insulation, is lightweight yet high-strength, and resistant to aging, with a smooth inner wall. It is widely used in chemical, power, and petroleum industries to protect cables and pipelines, transport corrosive media, and can be used stably for long periods in harsh environments.
[0003] To protect cables, fiberglass sleeves are usually used. Currently, existing fiberglass sleeves are connected using traditional threads or flanges. This method requires repeated alignment, tightening of bolts, or rotation of threads, which is not only time-consuming and labor-intensive, but also requires workers to have high experience and skills. The connection process often involves repeated adjustments due to problems such as inaccurate positioning and poor sealing, which affects construction efficiency and greatly increases the workload of workers. Utility Model Content
[0004] To overcome the above-mentioned defects, this utility model provides a fiberglass sleeve with strong protective properties. It solves the problem that the existing fiberglass sleeves are connected using traditional threads or flanges. This method requires repeated alignment, tightening of bolts or rotation of threads, which is not only time-consuming and labor-intensive, but also requires workers to have high experience and skills. The docking process is often repeatedly adjusted due to problems such as inaccurate positioning and poor sealing, which affects the construction efficiency and greatly increases the workload of the workers.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass sleeve with strong protective properties, comprising a sleeve body, a connecting frame on the sleeve body, two slots on the connecting frame, a movable plate slidably installed in the slots, two toothed plates (first type) mounted on the movable plate, two toothed plates (second type) slidably installed in the slots, the toothed plates (first type) meshing with the toothed plates (second type), four return springs installed in the slots, two return springs forming a group, the return springs connected to the toothed plates (second type), two spring rods installed in the slots, the ends of the spring rods connected to locking blocks, a locking groove opened at the bottom of the toothed plates (second type), four push-pull rods slidably installed through the connecting frame, the ends of the push-pull rods connected to the toothed plates (second type), and two limiting grooves opened inside the sleeve body.
[0006] As a further embodiment of this utility model: the sleeve body is provided with a fixing ring, the fixing ring is connected to the moving plate, and the fixing ring and the connecting frame are provided with a number of positioning holes corresponding to the positions.
[0007] As a further embodiment of this utility model: a plurality of positioning posts are installed on the sleeve body, the positioning posts are located in the positioning holes, and the end of the push-pull rod is connected to a handle.
[0008] As a further embodiment of this utility model: a limiting plate is installed in the limiting groove, a rubber sleeve is connected to the limiting plate, and several screw holes with corresponding positions are opened on the limiting plate and the sleeve body.
[0009] As a further embodiment of this utility model: the screw hole is internally threaded with a fixing bolt, and the connecting frame is provided with four sliding grooves, with two sliding grooves forming a group.
[0010] As a further embodiment of this utility model: a slide plate is slidably connected within the slide groove, and the slide plate is fixedly mounted on the movable plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This highly protective fiberglass sleeve, equipped with a second toothed plate, a first toothed plate, a return spring, and a push-pull rod, allows for quick connection of fiberglass sleeves during operation. When connecting two sleeves, place them on the connecting frame and press down on the fixing ring until it is flush against the frame. During this process, the movement of the fixing ring moves the moving plate, which in turn moves the two first toothed plates. As the first toothed plate moves, it presses against the second toothed plate, causing it to shift within the groove. Since the return spring is connected to the second toothed plate, its movement compresses the spring, generating a restoring elastic force. Once installed, this elastic force keeps the second toothed plate flush against the first toothed plate. To disassemble, pull the handle to move the push-pull rod. Once the second toothed plate separates from the first toothed plate, the fixing ring can be removed. This allows for rapid connection of the fiberglass sleeves, reducing worker fatigue and improving work efficiency.
[0012] This highly protective fiberglass sleeve, equipped with limiting plates, screw holes, a rubber sleeve, and fixing bolts, allows for easy installation. During operation, the worker first aligns the two limiting plates with the two limiting slots, then pushes the rubber sleeve. As the rubber sleeve moves within the sleeve body, it moves the two connected limiting plates until they reach the appropriate positions. At this point, the limiting plates align with the screw holes on the sleeve body, allowing the fixing bolts to be installed. The rubber sleeve reduces the impact on the cable during subsequent cable installation, thus protecting the cable. Attached Figure Description

Detailed Implementation
[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0015] like Figure 1-5 As shown, this utility model provides a technical solution: a fiberglass sleeve with strong protective properties, including a sleeve body 1, a fixing ring 3 on the sleeve body 1, the fixing ring 3 being connected to a movable plate 12, and a plurality of positioning holes 11 corresponding to the positions of the fixing ring 3 and the connecting frame 2. Because of the positioning holes 11, during the connection process, the sleeve body 1 can be quickly placed on the connecting frame 2 by the cooperation of the positioning pin 4 and the positioning holes 11, which facilitates subsequent work.
[0016] Several positioning pins 4 are installed on the sleeve body 1. The positioning pins 4 are located in the positioning holes 11. The end of the push-pull rod 18 is connected to a handle 5. Because the handle 5 is installed, when the handle 5 is pulled during the disassembly of the sleeve body 1, the push-pull rod 18 will move. The movement of the push-pull rod 18 will cause the toothed plate 16 to move. When the toothed plate 16 separates from the toothed plate 15, the fixing ring 3 can be removed, which facilitates disassembly.
[0017] The sleeve body 1 is provided with a connecting frame 2, which has two slots 10. A movable plate 12 is slidably installed in the slots 10. Two toothed plates 15 are installed on the movable plate 12. Two toothed plates 16 are slidably installed in the slots 10. The toothed plates 15 and 16 mesh with each other. Four return springs 14 are installed in the slots 10. Two return springs 14 form a group and are connected to the toothed plates 16. Two spring rods 21 are installed in the slots 10. Because of the spring rods 21, during disassembly, the toothed plates 16 will squeeze the locking block 19 and the spring rods 21 during the movement. The elastic force generated by the squeezed spring rods 21 will be transmitted to the locking block 19. When the toothed plates 16 move to the appropriate position, the locking block 19 will lock into the locking groove 17, thereby preventing the return springs 14 from driving the toothed plates 16 to reset.
[0018] A locking block 19 is connected to the end of the spring rod 21. A locking groove 17 is opened at the bottom of the toothed plate 2. Four push-pull rods 18 are slidably installed through the connecting frame 2. The ends of the push-pull rods 18 are connected to the toothed plate 2. Two limiting grooves 7 are opened in the sleeve body 1. Limiting plates 22 are installed in the limiting grooves 7. Rubber sleeves 6 are connected to the limiting plates 22. Several screw holes 8 corresponding to the positions are opened on the limiting plates 22 and the sleeve body 1. A sliding plate 20 is slidably connected in the sliding groove 13. The sliding plate 20 is fixedly installed on the moving plate 12. Because of the installation of the rubber sleeve 6, the two connected limiting plates 22 will move when the rubber sleeve 6 is pushed until the limiting plates 22 move to the appropriate position. At this time, the limiting plates 22 and the screw holes 8 opened on the sleeve body 1 correspond. Then the fixing bolts 9 can be installed in the screw holes 8. By installing the rubber sleeve 6, the impact force on the cable during subsequent cable installation can be reduced, which plays a role in protecting the cable.
[0019] A slide plate 20 is slidably connected inside the slide groove 13, and the slide plate 20 is fixedly installed on the movable plate 12.
[0020] The working principle of this utility model is as follows: When it is necessary to connect the fiberglass sleeves, the two fiberglass sleeves are connected and placed on the connecting frame 2. Then, the fixing ring 3 is pressed down until the fixing ring 3 is close to the connecting frame 2. During this process, the movement of the fixing ring 3 will drive the moving plate 12 to move. The moving plate 12 will drive the two toothed plates 15 to move. During the movement, the toothed plates 15 will squeeze the toothed plates 16, causing the toothed plates 16 to move within the slot 10. Since the return spring 14 is connected to the toothed plates 16, the movement of the toothed plates 16 will squeeze the return spring 14, causing it to generate a restoring elastic force. After installation, the elastic force will make the toothed plates 16 close to the toothed plates 15. When it is necessary to disassemble, pull the handle 5 to drive the push-pull rod 18 to move. When the toothed plates 16 and the toothed plates 15 are separated, the fixing ring 3 can be removed. When working, the staff first aligns the two limiting plates 22 with the two limiting grooves 7 respectively, and then pushes the rubber sleeve 6. When the rubber sleeve 6 moves inside the sleeve body 1, it will drive the two connected limiting plates 22 to move until the limiting plates 22 move to the appropriate position. At this time, the limiting plates 22 correspond to the screw holes 8 opened on the sleeve body 1, and then the fixing bolts 9 can be installed in the screw holes 8.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.
