[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is described and illustrated below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] The present invention provides an underwater locking device. Figure 1-7 As shown, the locking device comprises at least a locking screw 1 and a tightening mechanism 2. The locking screw 1 has a threaded end 101 at one end and a non-threaded end 102 at the other end. A rotatable baffle 103 is provided on the non-threaded end 102, which is used to pass through the reserved holes of the two templates 3 to be locked. The tightening mechanism 2 consists of an internally threaded nut 201 and a handle 202 for rotating the nut 201. The nut 201 cooperates with the threaded end 101 of the locking screw 1, and the handle 202 is used to drive the nut 201 to move axially along the locking screw 1. A clamping space is formed between the baffle 103 and the tightening mechanism 2 for fixing the two templates 3 therebetween. The underwater locking device realizes the locking operation through the cooperation of the tightening mechanism 2 and the locking screw 1; the baffle 103 of the non-threaded end 102 is rotatably arranged, and when the locking screw 1 passes through the reserved holes of the two templates 3, the nut 201 in the tightening mechanism 2 moves axially along the locking screw 1 under the drive of the handle 202, so that the two templates 3 are pressed between the baffle 103 and the nut 201, thereby realizing the locking and fixation of the two templates 3; the utility model has a simple structure, is easy to disassemble and assemble underwater, can adapt to templates 3 of different thicknesses, and is quick and efficient to operate.

[0036] Furthermore, the non-threaded end 102 is provided with a baffle groove 104 extending along the axial direction of the locking screw 1. The baffle 103 is rotatably mounted in the baffle groove 104. When the locking screw 1 passes through the reserved holes of the two templates 3, the baffle 103 is parallel to the long axis of the baffle groove 104. When the locking screw 1 is used to lock the two templates 3, the baffle 103 is rotated so that the baffle 103 is perpendicular to the long axis of the baffle groove 104. The design of the baffle groove 104 allows the baffle 103 to rotate smoothly during underwater operations. After passing through the reserved holes of the templates 3, the baffle 103 can be adjusted to a position perpendicular to the long axis of the locking screw 1, forming a secure locking structure, thereby fixing the two templates 3 in the clamping space. By providing the baffle groove 104 , the angle of the baffle 103 can be easily adjusted according to the installation requirements of the template 3 , thereby improving the convenience and accuracy of underwater operation, ensuring the stability of the locking, and effectively preventing the template 3 from loosening.

[0037] In some embodiments, the shape of the baffle groove 104 can be modified according to different fixing requirements, and the length and width of the baffle groove 104 can also be adjusted to accommodate baffles 103 of different specifications.

[0038] Furthermore, the non-threaded end 102 is further provided with a sliding groove 105 extending therethrough. The sliding groove 105 is perpendicular to the baffle groove 104. The baffle 103 moves back and forth along the sliding groove 105. A baffle shaft 106 is provided on the baffle 103. The baffle shaft 106 passes through the sliding groove 105, allowing the baffle 103 to rotate within the baffle groove 104. When the baffle 103 rotates around the baffle shaft 106 to a position perpendicular to the baffle groove 104, the baffle 103 is pushed along the sliding groove 105 to the end of the sliding groove 105 away from the threaded end 101, thereby fixing the baffle 103 at the positioning point, thereby achieving a stable positioning of one end of the two templates 3. This structural improvement enables the locking device to not only effectively lock the template 3, but also accurately control the position of the template 3 through the positioning function of the baffle 103, thereby increasing the operational stability and fixing accuracy of the locking device and achieving a more reliable template 3 fixing effect in an underwater environment.

[0039] Furthermore, baffle 103 is shaped like a rectangular parallelepiped, with its long side parallel to the long axis of baffle slot 104. It can rotate about baffle axis 106 to a position perpendicular to the long axis of baffle slot 104. The rectangular parallelepiped structure of baffle 103 allows it to quickly align with baffle slot 104 during rotation. By rotating baffle 103 underwater, an operator can quickly rotate baffle 103 from a parallel position to a perpendicular position, effectively locking template 3. The rectangular parallelepiped structure facilitates underwater adjustment of the angle of baffle 103, achieving a better locking effect, providing stable fixing force, and simplifying the structural design of the locking device.

[0040] In some embodiments, the shape of the baffle 103 can be changed to other shapes, such as an ellipse or a trapezoid, according to the water flow resistance or the requirements of the template 3, so as to improve the adaptability in a specific underwater environment.

[0041] Furthermore, the thickness of baffle 103 is identical to the width of baffle slot 104, ensuring that baffle 103 remains stable within baffle slot 104. This ensures that baffle 103 does not deviate during rotation and movement, maintaining excellent stability. This design reduces the shaking of baffle 103 during underwater operation. The tight fit between baffle 103 and baffle slot 104 provides greater stability in underwater environments, preventing loosening due to water flow and ensuring that the locking device maintains high stability during the locking process.

[0042] Furthermore, a circular groove 107 is provided at one end of the baffle groove 104 away from the threaded end 101. The diameter of the circular groove 107 is greater than the width of the baffle groove 104, so as to form an operating space at one end of the baffle groove 104. The circular groove 107 provides additional operating space, making it convenient for the operator to adjust the angle or install the baffle 103 underwater using tools or manually. The design of the circular groove 107 effectively prevents the baffle 103 from getting stuck, ensuring smooth operation of the device. The increase in operating space makes underwater installation more convenient, and the improvement in operating space also improves the flexibility and operating efficiency of the device underwater.

[0043] In some embodiments, the shape of the circular groove 107 can be changed to an elliptical shape or a polygonal shape according to operational requirements, so as to adapt to the use of different tools.

[0044] Furthermore, the threaded end 101 of the locking screw 1 can be screwed into the nut 201 of the tightening mechanism 2. Driven by the rotating handle 202, the nut 201 moves axially along the locking screw 1 until it approaches the baffle 103, locking the two templates 3 in the clamping space between the baffle 103 and the nut 201. The tightening mechanism 2 screws the nut 201 into the threaded end 101 of the locking screw 1, causing the nut 201 to move axially along the screw 1 until it reaches the baffle 103. At this point, the two templates 3 are clamped in the clamping space between the baffle 103 and the nut 201. Further tightening of the nut 201 achieves a secure locking effect. The tightening mechanism 2 ensures precise positioning of the nut 201, making underwater tightening simple and reliable. This embodiment allows the operator to quickly tighten the templates 3 with a single rotation of the handle 202, improving the efficiency of underwater operations and reducing the reliance on tools during the tightening process. This design also ensures the stability of the template 3 in the clamping space, adapts to the complex underwater environment, and increases the reliability of the locking device.

[0045] Furthermore, the underwater locking device also includes a number of gaskets (not shown in the figure), which are arranged between the locking screw 1 and the tightening mechanism 2 to adapt to templates 3 of different thicknesses. The gaskets are arranged between the locking screw 1 and the tightening mechanism 2 to fill the gaps in the template 3 so that the locking device can adapt to templates 3 of different thicknesses. In actual operation, the operator can flexibly increase or decrease the number of gaskets according to the thickness of the template 3, thereby ensuring the accuracy of the clamping space during locking and improving the overall locking effect. The use of gaskets makes the underwater locking device more applicable, can quickly adapt to templates 3 of different thicknesses, avoids the problem of weakening of the locking effect due to changes in the thickness of the template 3, and improves the versatility and ease of operation of the device.

[0046] In some embodiments, the gasket material can be selected from different types of corrosion-resistant materials, such as stainless steel, polyurethane or rubber, to adapt to different underwater environments. In addition, according to actual needs, the thickness of the gasket can be designed to different specifications to meet more precise adjustment needs.

[0047] Furthermore, a rotating shaft 203 is provided on the nut 201, and the handle 202 is rotatably mounted on the rotating shaft 203. By providing the rotating shaft 203 on the nut 201, the handle 202 can rotate freely around the rotating shaft 203. When the operator rotates the handle 202, the nut 201 moves along the axial direction of the locking screw 1, thereby achieving the clamping operation of the template 3. The design of the rotating shaft 203 provides a stable operating platform, ensuring the rotation accuracy of the nut 201 and making the operation process smoother. By rotatably mounting the handle 202 on the rotating shaft 203 of the nut 201, the operator can easily control the nut 201 and maintain a good operating experience even in an underwater environment. This design not only increases the operating comfort, but also reduces the rotation resistance and improves the durability of the locking device.

[0048] Furthermore, one end of the handle 202 is U-shaped, with the two ends of the U-shaped opening respectively arranged at the two ends of the rotating shaft 203, and the other end of the handle 202 is rod-shaped for hand-holding. By designing the handle 202 as a U-shaped structure, with the two ends of the U-shaped structure respectively fixed at the two ends of the rotating shaft 203, the handle 202 is easier to hold and rotate underwater. The other end of the rod provides the operator with a stable grip, which is suitable for precise rotation operations in underwater environments. The U-shaped handle 202 design increases the stability of the grip and effectively avoids slipping during underwater operations, thereby improving the controllability and comfort of the device. The rod-shaped handle 202 provides the operator with better grip and torque, making it easier to overcome resistance and complete the locking operation underwater.

[0049] The working process of the above-mentioned underwater locking device is as follows:

[0050] After the non-threaded end 102 of the locking screw 1 is passed through the reserved hole of the template 3, the baffle 103 is rotated so that the baffle 103 is perpendicular to the long axis of the baffle groove 104 and moves along the sliding groove 105 to the end of the sliding groove 105 away from the threaded end 101. The nut 201 in the tightening mechanism 2 is then moved axially along the screw 1 to clamp the two templates 3 between the baffle 103 and the nut 201, completing the secure locking. After installation, the operator can check the stability of the locking device and, if necessary, loosen the nut 201 by rotating the handle 202 in the opposite direction and retract the baffle 103, thereby achieving quick and easy disassembly.

[0051] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
