Description

Technical Field

[0001] This utility model relates to the field of rubber fenders, specifically a rubber fender with a chain quick-release structure. Background Technology

[0002] In ports, docks and other places with frequent water transport operations, rubber fenders play a vital role as key devices for protecting dock facilities and berthing ships. Traditional rubber fenders are usually composed of a rubber body, an internal buffer mechanism and connecting chains and other components.

[0003] Existing rubber fenders have revealed numerous problems during long-term use. The chains connecting the rubber fenders to the dock or ship are prone to wear and corrosion due to the long-term impact of ship berthing, seawater erosion, and the complex outdoor environment. When it is necessary to replace the chains, the operation is often cumbersome. Traditional connection methods mostly use welding, riveting, or complex bolt fastening structures, which makes chain disassembly not only time-consuming and laborious but also often requires specialized tools, significantly increasing maintenance and time costs. Furthermore, the internal buffer mechanism of the rubber fender, as the core component for absorbing ship collision energy, will gradually deteriorate under frequent impacts. However, due to the overall structural design of the rubber fender, replacing the internal buffer mechanism is also very difficult. Therefore, it is necessary to design a rubber fender with a quick-release chain structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rubber fender with a chain quick-release structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber fender with a chain quick-release structure, including a base, a rubber cylinder fixedly installed at the rear of the base, a fixing ring fixedly installed at the rear of the rubber cylinder, an insert slidably connected inside the fixing ring, and a contact plate fixedly installed at the rear of the insert.

[0006] The insert is slidably connected to a first sliding plate, a spring is welded to the surface of the first sliding plate, and a second sliding plate is welded to the front end of the spring.

[0007] Preferably, hooks are fixedly installed on both sides of the contact plate surface, and chains are slidably connected to the inner side of the hooks. Slide grooves are opened on both sides of the contact plate surface, and sliders are slidably connected inside the slide grooves. Limit rods are fixedly installed on the surface of the sliders.

[0008] Preferably, the surface of the contact plate is rotatably connected to a threaded rod via a bracket, the threaded rod is internally threaded to a threaded sleeve, and a stop rod is fixedly installed on the surface of the threaded sleeve.

[0009] Preferably, J-shaped rods are fixedly installed on both sides of the bottom of the abutment rod.

[0010] Preferably, one end of the J-shaped rod passes through the fixing ring and extends into the interior of the fixing ring.

[0011] Preferably, the bottom of the fixing ring is provided with limiting grooves on both sides for use with the J-shaped rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This rubber fender with a chain quick-release structure, by rotating the threaded rod, causes the threaded sleeve to descend, which in turn causes the abutment rod to descend, which in turn causes the J-shaped rod to descend. After the J-shaped rod descends to the outside of the limiting groove, it no longer limits the fixed ring. At this time, the contact plate can be removed from the rear of the fixed ring. After the contact plate is removed, it is convenient to replace the first sliding plate, spring and second sliding plate inside the fixed ring.

[0014] 2. This rubber fender with a chain quick-release structure allows the threaded rod to be rotated, causing the threaded sleeve to descend. The descending threaded sleeve then causes the abutment rod to descend. After the abutment rod descends, it no longer limits the limit rod. At this point, both limit rods can be slid towards the middle simultaneously. After the limit rods slide, the chain can slide out of the hook, achieving the effect of facilitating quick removal and replacement of the chain. Attached Figure Description

[0020] 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.

[0021] Example 1

[0022] Please refer to Figure 1-4 As shown, this utility model provides a rubber fender with a chain quick-release structure, including a base 1, a rubber cylinder 2 fixedly installed at the rear of the base 1, a fixing ring 3 fixedly installed at the rear of the rubber cylinder 2, an insert 5 slidably connected inside the fixing ring 3, and a contact plate 4 fixedly installed at the rear of the insert 5.

[0023] Specifically, the insert 5 has a first sliding plate 6 slidably connected inside, a spring 7 welded to the surface of the first sliding plate 6, a second sliding plate 8 welded to the front end of the spring 7, hooks 9 fixedly installed on both sides of the surface of the contact plate 4, a chain 10 slidably connected to the inside of the hooks 9, a sliding groove 11 opened on both sides of the surface of the contact plate 4, a slider 12 slidably connected inside the sliding groove 11, a limit rod 13 fixedly installed on the surface of the slider 12, a threaded rod 14 rotatably connected to the surface of the contact plate 4 via a bracket, a threaded sleeve 15 threadedly connected inside the threaded rod 14, and a stop rod 16 fixedly installed on the surface of the threaded sleeve 15. By setting the stop rod 16 and rotating the threaded rod 14, the threaded rod 14 causes the threaded sleeve 15 to descend, and the descending of the threaded sleeve 15 causes the stop rod 16 to descend. After the stop rod 16 descends, it no longer limits the limit rod 13. At this time, the two limit rods 13 can slide towards the middle at the same time. After the limit rods 13 slide, the chain 10 can slide out from the hook 9, achieving the effect of facilitating quick removal and replacement of the chain 10.

[0024] Specifically, J-shaped rods 17 are fixedly installed on both sides of the bottom of the abutment rod 16. One end of the J-shaped rod 17 passes through the fixing ring 3 and extends into the interior of the fixing ring 3. Limiting grooves 18 that cooperate with the J-shaped rod 17 are opened on both sides of the bottom of the fixing ring 3. By setting the J-shaped rod 17 and rotating the threaded rod 14, the threaded rod 14 rotates and drives the threaded sleeve 15 to descend. The descending of the threaded sleeve 15 drives the abutment rod 16 to descend. The descending of the abutment rod 16 drives the J-shaped rod 17 to descend. After the J-shaped rod 17 descends to the outside of the limiting groove 18, the J-shaped rod 17 no longer limits the fixing ring 3. At this time, the contact plate 4 can be removed from the rear of the fixing ring 3. After the contact plate 4 is removed, it is convenient to replace the first sliding plate 6, spring 7 and second sliding plate 8 inside the fixing ring 3.

[0025] Working principle: This utility model is a rubber fender with a chain quick-release structure. By rotating the threaded rod 14, the threaded rod 14 drives the threaded sleeve 15 to descend. The descending of the threaded sleeve 15 drives the abutment rod 16 to descend. After the abutment rod 16 descends, it no longer limits the limiting rod 13. At this time, the two limiting rods 13 can slide towards the middle at the same time. After the limiting rods 13 slide, the chain 10 can slide out from the hook 9, which can facilitate the quick removal and replacement of the chain 10. When it is necessary to replace the spring 7, the threaded rod 14 can be rotated. The rotation of the threaded rod 14 drives the threaded sleeve 15 to descend. The descending of the threaded sleeve 15 drives the abutment rod 16 to descend. The descending of the abutment rod 16 drives the J-shaped rod 17 to descend. After the J-shaped rod 17 descends to the outside of the limiting groove 18, the J-shaped rod 17 no longer limits the fixing ring 3. At this time, the contact plate 4 can be removed from the rear of the fixing ring 3. After the contact plate 4 is removed, it can facilitate the replacement of the first sliding plate 6, spring 7 and second sliding plate 8 inside the fixing ring 3.
