Description

Technical Field

[0001] This utility model relates to the field of gravity-type closure devices, specifically a gravity-type closure device suitable for long-arm operations on water. Background Technology

[0002] A gravity-operated closure is a device that closes by its own weight or the weight of a load. It is commonly used in clamps, doors, and other similar equipment to enable opening and closing actions without external power. Its working principle is that gravity causes the closure's components to automatically close or open under specific conditions, offering advantages such as simple structure and easy maintenance.

[0003] When using an underwater sampling device, a sample must first be taken using the device. Then, by pulling the pin, a weight is lowered and falls onto the sampling device, thus shutting it off. When the sampling device is pulled up by the steel cable, the weight is lifted and returned to its original position for subsequent use. However, during the descent of the weight, because the bottom of the weight needs to fit with the sampling device, there is a large gap at the bottom, making it impossible for the bottom to fit properly with the steel cable. This results in a certain position at the bottom of the weight, which may prevent the sampling device from being shut off directly. Furthermore, because it cannot fit properly with the steel cable, misalignment may occur when returning to its original position, requiring subsequent alignment, making it inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies and solve the problem that the bottom of the heavy object needs to be matched with the sampling device, resulting in a large space at the bottom of the heavy object that makes it impossible to fit with the steel cable, causing a certain position at the bottom of the heavy object, which may prevent the sampling device from being closed directly. Furthermore, because it cannot fit with the steel cable, misalignment may occur when restoring it to its original position, requiring subsequent alignment and causing inconvenience in use, this utility model proposes a gravity-type closure device suitable for long-arm operations on water.

[0005] A gravity-type closure device suitable for long-arm operations on water includes a weight with a slot inside. A steel cable is slidably connected inside the weight. An adapter assembly is provided inside the weight. The adapter assembly includes four limiting rods fixedly connected inside the weight. A limiting ring is fixedly connected between the four limiting rods. A support rod is slidably connected inside the limiting ring. An adapter block is fixedly connected to the end of the support rod. A screw is threaded inside the support rod. The screw passes through the weight and is rotatably connected. A knob is fixedly connected to the end of the screw.

[0006] Preferably, a reset assembly is provided on the outside of the weight. The reset assembly includes a sleeve that is slidably connected to the outside of the weight. The inside of the weight is slidably connected to the outside of the steel cable. Two metal rings are fixedly connected to the top of the sleeve, and a limit rope is fixedly connected to the outside of the metal rings.

[0007] Preferably, a limiting component is provided on the outer side of the sleeve. The limiting component includes a connecting cylinder fixedly connected to the outer side of the sleeve. A pin is slidably connected inside the connecting cylinder. A hanging ring is fixedly connected to one end of the pin, and an insertion ball is fixedly connected to the other end. The insertion ball is slidably connected to the inside of the slot.

[0008] Preferably, the limiting component further includes a limiting plate fixedly connected to the outside of the connecting cylinder, the outside of the limiting plate being slidably connected to the inside of the connecting cylinder, and a spring being fixedly connected between the limiting plate and the connecting cylinder.

[0009] Preferably, a pulling assembly is provided on the outer side of the limiting plate. The pulling assembly includes two first connecting rods fixedly connected to the outer side of the limiting plate. The first connecting rods pass through the connecting cylinder and are slidably connected. A connecting plate is fixedly connected to the end of each of the first connecting rods. A second connecting rod is fixedly connected to the inner side of each of the two connecting plates.

[0010] Preferably, the pulling assembly further includes a metal pull rod fixedly connected between the two second connecting rods, an auxiliary ring fixedly connected between the two connecting plates, the outer side of the auxiliary ring being slidably connected to the inside of the connecting cylinder, the inside of the metal pull rod being slidably connected to the outer side of the hanging ring, and a pull rope fixedly connected to the end of the metal pull rod.

[0011] Preferably, the adapter block is set as a semi-circle, and the combination of two adapter blocks forms a semi-circle.

[0012] The advantages of this utility model are: 1. This utility model uses a knob to rotate a screw, which in turn moves a support rod, causing two adapter blocks to move closer together. The adapter blocks then move to the outside of the steel cable and surround it, thus limiting the movement range of the weight's bottom. This prevents the weight from moving out of its original range during ascent and descent, ensuring the sampling device can be easily shut off and the weight can be easily returned to its original position afterward. This facilitates subsequent use and improves the device's convenience.

[0013] 2. This utility model moves a metal pull rod by pulling a rope, which in turn moves the second and first connecting rods, thereby moving the connecting plate, which in turn moves the auxiliary ring, which in turn moves the limiting plate, which in turn moves the pin, allowing the heavy object to descend. The connecting plate, the first connecting rod, and the second connecting rod ensure that the pulling force is directly applied to the pin, allowing the pin to move smoothly with each pull, thus improving the ease of pulling the pin and enhancing the convenience of the device.

[0017] 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.

[0018] Example 1 Please see Figure 1-4As shown, a gravity-type closure device suitable for long-arm operations on water includes a weight 1, a slot 2 inside the weight 1, a steel cable 3 slidably connected inside the weight 1, and an adapter component inside the weight 1. The adapter component includes four limiting rods 4 fixedly connected inside the weight 1, limiting rings 5 ​​fixedly connected between the four limiting rods 4, a support rod 6 slidably connected inside the limiting ring 5, an adapter block 7 fixedly connected to the end of the support rod 6, a screw 8 threadedly connected inside the support rod 6, the screw 8 passing through the weight 1 and rotatably connected, and a knob 9 fixedly connected to the end of the screw 8.

[0019] During operation, rotating the knob 9 drives the screw 8 to rotate, which in turn moves the support rod 6, causing the two adapter blocks 7 to move closer together. This moves the adapter blocks 7 to the outside of the steel cable 3 and surrounds the steel cable 3, thus limiting the movement range of the bottom of the weight 1. This ensures that the weight 1 will not leave its original range when rising and falling, thus ensuring that the sampling device can be shut down smoothly and that the weight 1 can be easily returned to its original position afterward, facilitating subsequent use and improving the convenience of the device.

[0020] The outer side of the weight 1 is provided with a reset assembly, which includes a sleeve 10 that is slidably connected to the outer side of the weight 1. The inside of the weight 1 is slidably connected to the outside of the steel cable 3. Two metal rings 12 are fixedly connected to the top of the sleeve 10, and a limit rope 13 is fixedly connected to the outside of the metal rings 12.

[0021] During operation, the position of the sleeve 10 can be restricted by the connection of the limiting rope 13 with the other devices, which facilitates the subsequent restriction of the position of the weight 1.

[0022] The sleeve 10 is provided with a limiting component on the outside. The limiting component includes a connecting cylinder 11 fixedly connected to the outside of the sleeve 10. A pin 14 is slidably connected inside the connecting cylinder 11. A hanging ring 15 is fixedly connected to one end of the pin 14, and an insertion ball 16 is fixedly connected to the other end. The insertion ball 16 is slidably connected to the inside of the slot 2.

[0023] The limiting assembly also includes a limiting disk 17 fixedly connected to the outside of the connecting cylinder 11. The outside of the limiting disk 17 is slidably connected to the inside of the connecting cylinder 11, and a spring 18 is fixedly connected between the limiting disk 17 and the connecting cylinder 11.

[0024] During operation, by pulling the pin 14 and compressing the spring 18 through the limiting plate 17, the insertion ball 16 is disengaged from the slot 2, allowing the weight 1 to descend smoothly. After the weight 1 descends, the spring 18 will drive the pin 14 to return to its original position, thus facilitating subsequent use.

[0025] Among them, the adapter block 7 is set as a semi-circle, and the combination of two adapter blocks 7 forms a semi-circle.

[0026] During operation, by setting the adapter block 7 to a semi-circular shape, the adapter block 7 can better surround the steel cable 3.

[0027] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of the present invention, a pulling component is provided on the outside of the limiting plate 17. The pulling component includes two first connecting rods 19 fixedly connected to the outside of the limiting plate 17. The first connecting rods 19 pass through the connecting cylinder 11 and are slidably connected. A connecting plate 20 is fixedly connected to the end of the first connecting rod 19. A second connecting rod 21 is fixedly connected to the inner side of each of the two connecting plates 20.

[0028] The pulling assembly also includes a metal pull rod 23 fixedly connected between two second connecting rods 21, an auxiliary ring 22 fixedly connected between two connecting plates 20, the outer side of the auxiliary ring 22 being slidably connected to the inside of the connecting cylinder 11, the inside of the metal pull rod 23 being slidably connected to the outer side of the hanging ring 15, and a pull rope 24 fixedly connected to the end of the metal pull rod 23.

[0029] During operation, pulling the rope 24 moves the metal rod 23, which in turn moves the second connecting rod 21 and the first connecting rod 19, thereby moving the connecting plate 20, which in turn moves the auxiliary ring 22, which in turn moves the limiting plate 17, which in turn moves the pin 14, allowing the weight 1 to descend. Through the connecting plate 20, the first connecting rod 19, and the second connecting rod 21, the pulling force can be directly applied to the pin 14, making the pin 14 move as it is pulled, thus improving the smoothness of pulling the pin 14 and enhancing the convenience of the device.

[0030] Working principle: When the heavy object 1 needs to be used, the knob 9 can be turned to drive the screw 8 to rotate, thereby driving the support rod 6 to move, so that the two adapter blocks 7 move closer to each other, and then move the adapter blocks 7 to the outside of the steel cable 3 and surround the steel cable 3, thereby limiting the movement range of the bottom of the heavy object 1, so that the heavy object 1 will not leave the original range when rising and falling. Then, pulling the rope 24 causes the metal rod 23 to move, which in turn moves the second connecting rod 21 and the first connecting rod 19, thereby moving the connecting plate 20, which in turn moves the auxiliary ring 22, which in turn moves the limit plate 17, which in turn moves the pin 14, so that the weight 1 can be lowered.
