Description

Technical Field

[0001] This utility model relates to the field of shipbuilding and repair technology and lifebuoy technology, and in particular to a lifebuoy retrieval and placement rack. Background Technology

[0002] Lifebuoys, as an important piece of water rescue equipment, are widely deployed in ships, docks, reservoirs, beaches, and other aquatic locations. To maintain the standardized, tidy storage and convenient retrieval of lifebuoys, specialized lifebuoy racks are typically used. To ensure that lifebuoys do not accidentally detach from the positioning plate in conditions such as ship rolling or strong winds, additional securing methods are usually employed, with rope binding being a common method. While this method provides a secure hold, the operation is relatively cumbersome. When storing lifebuoys, operators need to perform binding and wrapping actions, involving multiple steps and consuming time and manpower, especially when storing multiple lifebuoys or performing routine inspections and maintenance. Furthermore, this process is time-consuming and prone to errors due to nervousness in emergency situations. A more significant problem is that when urgently retrieving a lifebuoy, the user must first untie the ropes before removing it from the rack, undoubtedly extending valuable rescue preparation time. Therefore, current technology lacks a lifebuoy rack that enables rapid retrieval and deployment of lifebuoys. Utility Model Content

[0003] The purpose of this invention is to develop a lifebuoy retrieval rack that can ensure the lifebuoy is securely stored when not in use, preventing accidental detachment, and also allow users to quickly remove the lifebuoy in an emergency, thereby greatly improving rescue efficiency.

[0004] This utility model is achieved through the following technical solution: A lifebuoy loading and unloading rack includes a mounting plate. A circular boss for placing a lifebuoy is located at the center of the front of the mounting plate. A rotating arm is located at the center of the back of the mounting plate, with its rotation center concentric with the center of the circular boss. On the back of the mounting plate, vertically extending sliding arms are located on both sides of the rotating arm. Each sliding arm is guided by a track assembly, allowing it to slide only laterally relative to the mounting plate. Each sliding arm has a clamping block extending to the front of the mounting plate at both vertical ends. A connecting rod is rotatably connected to each end of the rotating arm, and the two ends of the rotating arm are respectively connected to the two sliding arms via the connecting rods. The connecting rods are rotatably connected to the sliding arms so that when the rotating arm rotates, it causes the two sliding arms to move closer or further apart laterally. The two sliding arms have a limiting position where they move closer together, causing the clamping block to abut against the outer wall of the lifebuoy placed on the circular boss. The track assembly includes an elastic element with an elastic tendency to drive the two sliding arms closer together and maintain the limiting position.

[0005] The beneficial effects of the above scheme are as follows: the circular boss provides initial positioning for the lifebuoy; when the two sliding arms slide laterally towards each other on the back of the mounting plate, the clamping blocks on each sliding arm also approach each other. Since each sliding arm has clamping blocks at both ends, a total of four clamping blocks can approach each other to circumferentially limit the lifebuoy placed on the circular boss. Furthermore, the two sliding arms will automatically approach each other and maintain this state under the action of the elastic element, so as to keep the clamping blocks stably pressing the lifebuoy and ensure that the lifebuoy will not accidentally fall off the mounting plate in environments such as ship rolling or strong winds. When it is necessary to remove the lifebuoy, it is only necessary to control one of the sliding arms to move (directly or indirectly), and the other sliding arm will follow, so that the clamping block no longer resists the lifebuoy. When placing the lifebuoy again, it is only necessary to control one of the sliding arms to move (directly or indirectly), and place the lifebuoy on the circular boss. The elastic element will drive the sliding arm and the clamping block to automatically limit the circumferential movement of the lifebuoy. The entire removal and placement operation is simple and convenient.

[0006] In one feasible embodiment, the track assembly includes a laterally extending track disposed on the back of the mounting plate, and the sliding arm is provided with a sliding block embedded in the track and engaging with the track for lateral sliding.

[0007] Furthermore, each track group includes two tracks that are vertically spaced and parallel to each other, ensuring stable lateral sliding of the sliding arm.

[0008] In one feasible embodiment, the track assembly includes a laterally extending track, and the sliding arm is provided with a sliding block embedded in the track and cooperating with the track to slide laterally. Each track is provided with a limiting block near one end of the rotating arm. The limiting block and the sliding block are connected by a tension spring (elastic element). The tension of the tension spring drives the two sliding arms to move closer to each other and maintain the limiting position.

[0009] In one feasible embodiment, at least one of the sliding arms is provided with an extension plate extending to the front of the mounting plate, and a grip handle is fixedly provided on the extension plate to facilitate the user to control the sliding arm to move outward.

[0010] In one feasible embodiment, each of the clamping blocks is connected to the sliding arm via a fixed base. A support seat is fixedly mounted on the fixed base, and a telescopic rod perpendicular to the surface of the sliding arm is slidably mounted inside the support seat. A clamping block is fixedly mounted on the top of the telescopic rod. The support seat has a threaded hole for fastening, and a hand-turning screw is threaded into the threaded hole. The hand-turning screw abuts against the telescopic rod for positioning. In order to better adapt to life rings of different thicknesses, the telescopic rod and the support seat are slidably connected, and the clamping position of the clamping block can be adjusted. After adjustment, the telescopic rod is limited by abutting against the hand-turning screw.

[0011] Furthermore, the clamping block has two extended clamping arms, on which clamping wheels are fixedly mounted. The two clamping wheels increase the contact area with the life ring, and the arc surface of the wheels is less likely to scratch the life ring, thus better limiting the position of the life ring.

[0012] Furthermore, the clamping wheel is made of a flexible material and has a smooth surface to avoid causing wear on the surface of the lifebuoy. Attached Figure Description

[0018] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments are described in detail below with reference to the accompanying drawings.

[0019] Example 1 As attached Figures 1 to 4As shown, this embodiment discloses a lifebuoy loading and unloading rack, including a mounting plate 11. A circular boss 12 for placing lifebuoys is provided at the center of the front of the mounting plate 11. A rotating arm 30 is provided at the center of the back of the mounting plate 11, with the rotation center of the rotating arm 30 concentric with the center of the circular boss 12. On the back of the mounting plate 11, vertically extending sliding arms 21 are provided on both sides of the rotating arm 30. Each sliding arm 21 is guided by a track assembly, allowing it to slide only laterally relative to the mounting plate 11. Each sliding arm 21 has a clamping block connected to both vertical ends extending to the front of the mounting plate 11. 71; Both ends of the rotating arm 30 are rotatably connected to a connecting rod 33, and both ends of the rotating arm 30 are respectively connected to two sliding arms 21 through the connecting rod 33. The connecting rod 33 is rotatably connected to the sliding arms 21 so that when the rotating arm 30 rotates, it drives the two sliding arms 21 to move closer or further apart in the lateral direction; the two sliding arms 21 have a limiting position where they move closer together so that the pressing block 71 abuts against the outer wall of the lifebuoy placed on the circular boss 12; the track assembly includes an elastic element, which has an elastic tendency to drive the two sliding arms 21 closer together and maintain the limiting position.

[0020] The track group includes a laterally extending track 41, and the sliding arm 21 is provided with a sliding block 42 that is embedded in the track 41 and cooperates with the laterally sliding movement of the track 41; each track group includes two tracks 41 that are vertically spaced and parallel to each other.

[0021] Each of the tracks 41 is provided with a limiting block 43 near one end of the rotating arm 30. The limiting block 43 is connected to the sliding block 42 by a tension spring 44. The tension of the tension spring 44 drives the two sliding arms 21 to move closer to each other and maintain the limiting position.

[0022] Furthermore, at least one of the sliding arms 21 is provided with an extension plate 51 extending to the front of the mounting plate 11, and a grip handle 52 is fixedly provided on the extension plate 51.

[0023] Furthermore, each of the clamping blocks 71 is connected to the sliding arm 21 via a fixed base 61. A support base 62 is fixedly mounted on the fixed base 61, and a telescopic rod 63 perpendicular to the surface of the sliding arm 21 is slidably mounted inside the support base 62. A clamping block 71 is fixedly mounted on the top of the telescopic rod 63. A fastening threaded hole is provided on the support base 62, and a hand-turning screw 64 is threaded into the fastening threaded hole. The hand-turning screw 64 abuts against and positions the telescopic rod 63. The clamping block 71 has two extending clamping arms, and a clamping wheel 72 is fixedly mounted on the clamping arms. The clamping wheel 72 is made of a flexible material and has a smooth surface. In this embodiment, a rubber material is used.

[0024] The working principle of Example 1 is as follows: First, by gripping the handle 52 and pushing outward, the corresponding sliding arm 21 will move outward. Then, the connecting rod 33 on the sliding arm 21 will move, thereby driving the rotating arm 30 to rotate. After the rotating arm 30 rotates, it will drive another connecting rod 33 to move, ultimately pushing the other sliding arm 21 outward. Both sliding arms 21 will move away from the circular boss 12 simultaneously. At this time, the two sliding arms 21 will not obstruct the placement and installation of the lifebuoy 13. After placing the lifebuoy 13 on the circular boss 12, release the handle 52. Under the tension of multiple tension springs 44, the two sliding arms 21 will automatically tighten towards the circular boss 12. The multiple pressure rollers 72 on the two sliding arms 21 can simultaneously press against the outer ring of the lifebuoy 13, thereby limiting the lifebuoy 13 and preventing it from falling.

[0025] When it is necessary to remove the life ring 13, simply hold the handle 52 with your hand and push outward. The two sliding arms 21 will move away from the circular boss 12 at the same time, and then the life ring 13 can be removed smoothly.

[0026] In addition, to better accommodate different thicknesses of lifebuoys 13, the telescopic rod 63 and the support base 62 are connected by a telescopic mechanism. After adjusting the extension length of the telescopic rod 63, it can be positioned by turning the screw 64. Furthermore, the telescopic rod 63 can be pulled out to limit the movement of multiple stacked lifebuoys 13, achieving efficient use of space.

[0027] Example 2 As attached Figure 5 As shown, in this embodiment 2, based on the first embodiment, a cylinder 81 is fixedly installed on the back of the mounting plate 11. The output shaft of the cylinder 81 is fixed to one of the sliding arms 21. The sliding arm 21 is pushed by the cylinder 81, which has two driving modes: manual and pneumatic. The cylinder drive is more convenient and labor-saving.
