Description

Technical Field

[0001] This utility model relates to the field of underwater propulsion technology, specifically to an anti-detachment grip mechanism for an underwater propulsion device. Background Technology

[0002] As the core power equipment in the fields of underwater operations and water sports, underwater propulsion has expanded its application scenarios from professional diving operations to recreational diving, underwater photography and water rescue. In actual operation, the grip is the only control connection between the user and the propulsion. Its stability and safety directly determine the user experience and operational safety of the equipment. Whether it is a diver adjusting his working posture in a complex underwater environment or a sports enthusiast maintaining his direction of travel in open water, they all need to rely on the grip to achieve precise control of the propulsion. Therefore, the anti-disengagement performance of the grip mechanism has become a key indicator for measuring the safety level of underwater propulsion. However, the current mainstream underwater propulsion grip mechanism still has significant design flaws and is difficult to cope with the use needs of complex underwater environments. In natural waters with strong currents (such as river estuaries and reef areas) or in scenarios where users need to perform large movements (such as underwater obstacle avoidance and emergency turning), traditional grips are very prone to detachment. To address the aforementioned grip detachment issue, the industry has attempted to use an "anti-loss rope" as a supplementary solution. This involves connecting a flexible rope between the grip and the user's wrist. While the anti-loss rope does prevent complete loss of the device when the thruster slips, this solution presents new safety hazards. When the thruster slips, its own power output generates a continuous traction force, which is directly transmitted to the user's wrist via the anti-loss rope. Since the anti-loss rope's connection point is concentrated in the relatively vulnerable wrist area, and the transmission of traction force is sudden and concentrated, the large instantaneous pulling force could potentially cause muscle strain, joint sprains, or even more serious limb injuries under high-speed traction, failing to meet the core safety requirements of underwater thrusters. Therefore, a mechanism for preventing detachment of the grip on an underwater propulsion device is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an anti-detachment grip mechanism for underwater propulsion, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An anti-detachment grip mechanism for an underwater thruster includes an underwater thruster body. A connecting arm is fixedly connected to the top of the underwater thruster body, and grip rods are fixedly connected to both ends of the connecting arm. An anti-detachment mechanism is sleeved on the bottom of the outer side of the grip rods, and an anti-detachment rope is installed at the rear end of the anti-detachment mechanism. The anti-detachment mechanism includes a wrist ring, and connecting blocks are fixed to both ends of the wrist ring. The outer side of the connecting blocks is slidably connected to the same sliding ring. A grooved rubber guard plate is fixedly installed on the inner side of the sliding ring, and a rubber rib is fixed to the back of the grooved rubber guard plate. An installation groove is formed on the rear surface of the sliding ring, and a tension buffer assembly is installed on the inner side of the installation groove. The tension buffer assembly includes two hinge seats, and a hinge rod is hinged to the inner side of each hinge seat. The two hinge rods are hinged to the same connecting seat. A rotating seat is fixed to the rear surface of the connecting seat, and a ball rod is rotatably connected inside the rotating seat. A connecting ring is fixed to the back of the ball rod.

[0005] As a further optimization of this utility model, the two hinge seats are symmetrically distributed from left to right, and the two hinge seats are respectively fixedly installed on one side of the two connecting blocks.

[0006] As a further optimization of this utility model, the rotating seat is located at the center of the rear surface of the connecting seat, and both ends of the rotating seat are spherical structures.

[0007] As a further optimization of this utility model, the outer side of the connecting ring is fixedly connected to the bottom end of the anti-slip rope, and the top end of the anti-slip rope is fixedly connected to the top of the grip.

[0008] As a further optimization of this utility model, the top and bottom ends of the wrist ring are fixedly connected with rubber guards, the outer side of the rubber guards has an arc-shaped structure, and the rubber guards are located in front of the connecting block.

[0009] As a further optimization of this utility model, the two corner areas on the outer side of the connecting block are both arc-shaped, and the connecting block extends to the rear of the sliding ring.

[0010] As a further optimization of this utility model, the number of rubber bands is set to two, the two rubber bands are symmetrically distributed from left to right, and the rubber bands are fixedly connected to the front surface of the connecting seat.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention addresses the problems of traditional underwater propulsion handles easily detaching and anti-loss ropes causing wrist injuries. By combining an anti-detachment mechanism with an anti-slip rope, multiple layers of protection are achieved. When not in use, the anti-detachment mechanism is fitted onto the handle, saving space. When in use, after the wrist is slipped in, if the hand accidentally detaches from the handle, the pulling force is transmitted through the anti-slip rope. The ball-shaped rod can rotate at multiple angles to prevent tangling, and the hinged structure reduces the distance between the wrist ring and the sliding ring to prevent wrist detachment. The rubber band and grooved rubber guard plate also provide multi-level buffering and force dissipation, avoiding concentrated pulling force that could injure the wrist. This design ensures operational safety while improving ease of use and comfort. Attached Figure Description

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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-7 This utility model provides a technical solution: An anti-detachment grip mechanism for an underwater thruster includes an underwater thruster body 1. A connecting arm 2 is fixedly connected to the top of the underwater thruster body 1, and grip rods 3 are fixedly connected to both ends of the connecting arm 2. An anti-detachment mechanism 4 is sleeved on the bottom of the outer side of the grip rods 3, and an anti-detachment rope 5 is installed at the rear end of the anti-detachment mechanism 4. The anti-detachment mechanism 4 includes a wrist ring 41, and connecting blocks 42 are fixedly connected to both ends of the wrist ring 41. A sliding ring 43 is slidably connected to the outer side of the connecting blocks 42, and a grooved rubber guard plate 44 is fixedly installed on the inner side of the sliding ring 43. A rubber rib 45 is fixed to the back of the protective plate 44, and an installation groove 46 is provided on the rear surface of the sliding ring 43. A tension buffer assembly 47 is installed on the inner side of the installation groove 46. The tension buffer assembly 47 includes two hinge seats 471. A hinge rod 472 is hinged to the inner side of each hinge seat 471. The same connecting seat 473 is hinged between the two hinge rods 472. A rotating seat 474 is fixed to the rear surface of the connecting seat 473. A ball rod 475 is rotatably connected inside the rotating seat 474. A connecting ring 476 is fixed to the back of the ball rod 475. As a further implementation of this solution, the two hinge seats 471 are symmetrically distributed from left to right, and the two hinge seats 471 are respectively fixedly installed on one side of the two connecting blocks 42. Specifically, two hinge seats 471, which are symmetrical on the left and right and fixed to one side of the connecting block 42, provide a stable hinge point for the hinge rod 472. Under the action of tension, the hinge rod 472 tilts back smoothly, causing the connecting block 42 to move back and reduce the distance between the wrist ring 41 and the sliding ring 43, ensuring that the anti-disengagement action is synchronous and stable, and improving the reliability of the anti-disengagement action. As a further implementation of this solution, the rotating seat 474 is located at the center of the rear surface of the connecting seat 473, and both ends of the rotating seat 474 are spherical structures. Specifically, it allows the ball rod 475 to rotate smoothly, flexibly adjust the angle to avoid the anti-slip rope 5 from getting tangled, and evenly transmits the tension to the connecting seat 473, so that the connecting seat 473 is balanced by the force and ensures that the tension buffer component 47 operates smoothly. As a further implementation of this solution, the outer side of the connecting ring 476 is fixedly connected to the bottom end of the anti-slip rope 5, and the top end of the anti-slip rope 5 is fixedly connected to the top end of the grip bar 3. Specifically, when the hand leaves the grip bar 3, the pulling force is quickly transmitted through the anti-slip rope 5 to the tension buffer component 47, triggering the anti-slip action and ensuring timely protective response; As a further implementation of this solution, a rubber guard strip 48 is fixedly connected to both the top and bottom of the wrist ring 41. The outer side of the rubber guard strip 48 has an arc-shaped structure, and the rubber guard strip 48 is located in front of the connecting block 42. Specifically, the curved rubber strips 48 at the top and bottom of the wrist ring 41 can prevent the wrist ring 41 from cutting the wrist, prevent the sliding ring 43 from moving too far forward, and also provide force cushioning to reduce the impact on the wrist and improve wearing comfort and safety. As a further implementation of this solution, the two corner areas on the outer side of the connecting block 42 are both arc-shaped structures. The connecting block 42 extends to the rear of the sliding ring 43. This setting is conducive to quickly reducing the distance between the wrist ring 41 and the sliding ring 43 when preventing disengagement. The connecting block 42 extends to the rear of the sliding ring 43, providing sufficient sliding space for the sliding ring 43 and ensuring the smooth operation of the anti-disengagement action. As a further implementation of this solution, two rubber ribs 45 are provided, which are symmetrically distributed from left to right, and the rubber ribs 45 are fixedly connected to the front surface of the connecting seat 473. Specifically, two symmetrical rubber bands 45 fixed to the front surface of the connecting seat 473 initially stretch and relieve force under tension, preparing for the secondary deformation buffer of the grooved rubber guard plate 44, achieving multi-level buffering, avoiding instantaneous concentrated tension that could damage the wrist, and improving the buffering effect and safety.

[0017] Workflow: When not in use, the anti-detachment mechanism 4 is fitted onto the bottom of the outside of the grip 3. The structure of the grip 3 allows for compact storage without taking up additional space for underwater operations or movement, making it convenient for users to carry and store equipment. At this time, the anti-detachment rope 5 remains naturally folded without excessive stretching due to the close proximity of the anti-detachment mechanism 4 and the grip 3. When the user needs to use the grip mechanism, first remove the anti-detachment mechanism 4 from the outside of the grip 3, and then pass the wrist through the gap between the wrist ring 41 and the sliding ring 43. At this time, the rubber protective strips 48 at the top and bottom of the wrist ring 41 fit against the skin of the wrist, which not only prevents the edge of the wrist ring 41 from cutting the wrist due to force, but also prevents the sliding ring 43 from moving too far forward towards the wrist, providing basic protection and position limitation for subsequent operations. The user grips the handle 3 and establishes a control connection with the underwater thruster body 1 through the connecting arm 2. The user then starts the underwater thruster body 1 to perform underwater operations or movements. During this process, the anti-detachment mechanism 4 naturally follows the hand's movements with the wrist, the sliding ring 43 remains stable along the outside of the connecting block 42, the rubber band 45 is in a naturally relaxed state, the tension buffer component 47 is not under force, and the overall mechanism does not interfere with normal gripping and control. If the user's hand accidentally detaches from the grip bar 3 due to fatigue, water flow impact, or accidental collision, the grip bar 3 will generate a pulling force under the power traction of the underwater propulsion unit 1. This pulling force is quickly transmitted to the connecting ring 476 through the anti-detachment rope 5. The connecting ring 476 drives the ball rod 475 to be subjected to force simultaneously. The ball rod 475 rotates flexibly inside the rotating seat 474 and can adjust the angle according to the direction of the pulling force to avoid the anti-detachment rope 5 from accidentally getting tangled due to a fixed angle, ensuring that the pulling force is stably transmitted to the connecting seat 473. After the connecting seat 473 is subjected to force, the hinge rods 472 at both ends of the connecting seat 473 tilt backward around the hinge seat 471, causing the connecting block 42 to slide backward along the inner side of the sliding ring 43, reducing the distance between the wrist ring 41 and the sliding ring 43, firmly clamping the wrist and preventing the wrist from separating from the anti-disengagement mechanism 4. At the same time, the front surface of the connecting seat 473 pulls the rubber rib 45, and the rubber rib 45 stretches and deforms, initially absorbing and weakening the tension, forming a first-level buffer. The tension continuously transmitted by the rubber rib 45 causes the grooved rubber guard plate 44 to undergo elastic deformation. Through the deformation of the guard plate itself, the tension energy is further absorbed, forming a second-level buffer. During this process, the grooved structure can disperse the deformation stress, avoid local damage to the grooved rubber guard plate 44, and at the same time, evenly transmit the remaining tension to the sliding ring 43. Finally, through the buffering effect of the rubber guard strip 48, the tension borne by the wrist is reduced to a safe range, preventing wrist muscle strain or joint sprain. When the user grips the handle 3 again or the underwater thruster body 1 stops power output and the pulling force disappears, the grooved rubber guard plate 44 returns to its original shape due to its own elasticity, the rubber rib 45 retracts and resets, driving the connecting seat 473 and the hinge rod 472 back to their initial positions, the connecting block 42 slides and resets along the sliding ring 43, the distance between the wrist ring 41 and the sliding ring 43 returns to its initial state, the ball rod 475 rotates back to the center position in the rotating seat 474, and the anti-detachment rope 5 naturally retracts. If continued use is required, the user can keep their wrist in the anti-detachment mechanism 4 and operate the equipment normally; if discontinued, the wrist is removed from between the wrist ring 41 and the sliding ring 43, the anti-detachment mechanism 4 is put back on the outside of the handle 3 to complete the storage, and it is ready for the next use.
