Abstract
Description
Technical Field
[0001] This application relates to the field of wrench technology, and more specifically, to a diving helmet adjustment wrench. Background Technology
[0002] In diving operations, the stability and sealing performance of a diving helmet are directly related to the diver's safety, and ensuring these properties often depends on the precise operation of multiple adjusting bolts on the helmet. The diving helmet adjusting wrench, as a specialized tool for operating these bolts, is crucial to both operational efficiency and safety due to its well-designed structure.
[0003] Currently, traditional diving helmet adjustment wrenches mostly adopt a one-piece structure. Although the manufacturing process is simple, it has obvious limitations. On the one hand, traditional wrenches can only be used with bolts of a single size, while diving helmets often have various types of fasteners such as internal and external hexagonal bolts, requiring divers to carry multiple tools for switching. On the other hand, the one-piece structure has a fixed operating angle, and in confined spaces, non-working parts are prone to collisions with precision instruments and sealing components on the helmet surface, potentially damaging the protective coating, affecting sealing performance, or even causing leaks and other safety hazards. Therefore, developing a dedicated wrench for diving helmets has become an urgent industry need. Utility Model Content
[0004] To overcome the above deficiencies, this application provides a diving helmet adjustment wrench to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:
[0006] A diving helmet adjustment wrench includes a sleeve and two notched grooves on both sides of the outer wall of the sleeve, and a connecting rod integrally formed at the top. The connecting rod has an arc groove at its top and a handheld post. A rectangular block is integrally formed at the bottom of the arc groove. A square hole I is formed at the middle of the handheld post, and its outer wall is interference-fitted with the arc surface end of the arc groove. The inner wall of the square hole I fits against the outer wall of the rectangular block. A first adjustment component and a second adjustment component are integrally formed at both ends of the handheld post.
[0007] Furthermore, the surface of the handheld column is frosted, and its length is twice that of the connecting rod.
[0008] Furthermore, the bottom end of the rectangular block is integrally formed with the bottom of the arc groove, and the top end extends out of the surface end of the connecting rod. The length of the extended end of the rectangular block is half the depth of the arc groove, and it is inserted into the inside of the block hole I.
[0009] Furthermore, the first adjusting component includes an end I and an internal hexagonal hole. The inner end of the end I is integrally formed with one end of the handheld post, and the internal hexagonal hole is formed on its surface.
[0010] Furthermore, the second adjustment component includes an end II, a square hole II, and an external hexagonal block. The inner end of the end II is integrally formed with the other end of the hand-held column, and the square hole II is formed on its surface. The external hexagonal block is integrally formed on its other side.
[0011] Furthermore, the depth of the square hole II matches the length of the extended end of the rectangular block, and they can also be inserted into each other, with the surface of the end II fitting against the top surface of the connecting rod.
[0012] Furthermore, the sleeve has an internal hexagonal shape and is interconnected with the two notched grooves.
[0013] This utility model has the following beneficial effects:
[0014] 1. This utility model features a multi-functional integrated design. The wrench integrates multiple adjustment functions into one unit. The socket has an internal hexagonal shape and a notch, allowing for tightening or loosening of both standard hexagonal bolts and irregularly shaped fasteners. The first adjustment component has an internal hexagonal hole suitable for adjusting another type of hexagonal bolt. The second adjustment component is equipped with an external hexagonal block to accommodate the needs of internal hexagonal bolt adjustments. This multi-functional integrated design allows divers to perform multiple adjustment tasks with just one tool in the diving environment, greatly improving the portability and efficiency of the equipment. Furthermore, the hexagonal shape inside the socket, the notch on the side wall, the internal hexagonal hole, and the external hexagonal block are designed for multiple bolt sizes on the same helmet.
[0015] 2. This utility model employs two methods: First, the square hole II is inserted into the rectangular block, allowing the diver to hold the handle and tighten or loosen the irregularly shaped bolts using the socket. Alternatively, the diver can directly hold the handle and tighten or loosen the corresponding bolts using the internal hexagonal hole or external hexagonal block. This split-type adjusting wrench effectively overcomes the angle limitations of traditional one-piece wrenches, adapts to underwater confined spaces, reduces contact between non-working parts and the helmet surface, effectively prevents scratches and collisions to precision components and sealing assemblies, and ensures the helmet's lifespan and sealing performance.

Detailed Implementation
[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0023] Example:
[0024] Please see Figure 1 , Figure 2 , Figure 4 A diving helmet adjustment wrench includes a sleeve 1 and two notches 2 on both sides of the outer wall of the sleeve 1, and a connecting rod 3 integrally formed at the top.
[0025] Among them, the sleeve 1 is made of high-strength material and is cylindrical in shape. Its interior is a hexagonal cavity, which is compatible with the hexagonal adjusting bolts commonly found on diving helmets.
[0026] The sleeve 1 has symmetrical notches 2 on both sides of its outer wall. Each notch 2 is set along the height of the sleeve 1. The width of the notch is designed according to the irregular part of the bolt. Both notches 2 are connected to the inner hexagonal cavity, which can reduce the interference between the sleeve 1 and the protruding structure on the helmet surface, and tighten and loosen the irregular bolts on the diving helmet.
[0027] The top of the sleeve 1 is integrally formed with a connecting rod 3 through a forging process. The connecting rod 3 is a cylindrical cuboid structure, and its axis is set perpendicular to the axis of the sleeve 1. The connection is rounded to enhance the structural strength. An arc groove 4 is opened in the middle of the top of the connecting rod 3. A rectangular block 6 is integrally formed in the bottom of the arc groove 4 and is fixedly connected to the hand-held column 5.
[0028] When using this wrench, the notch 2 of the socket 1 is inserted into the adjusting nut of the diving helmet, and torque is applied through the handheld post 5. The interference fit between the rectangular block 6 and the square hole I 7 restricts the radial displacement of the handheld post 5, preventing underwater swaying; the arc surface design of the arc groove 4 allows the handheld post 5 to be finely adjusted within a range of ±15° to adapt to the curved operating space of the helmet. The dual adjustment components 89 can be switched as needed to achieve adjustment of multiple parts such as the helmet breathing assembly and the mask locking mechanism.
[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A diving helmet adjustment wrench includes a connecting rod 3 with an arc groove 4 at the top and a handhold post 5. A rectangular block 6 is integrally formed at the bottom of the arc groove 4. A square hole I 7 is formed at the middle of the handhold post 5, and the outer wall of the square hole I 7 is interference-fitted with the arc surface end of the arc groove 4. The inner wall of the square hole I 7 fits against the outer wall of the rectangular block 6. A first adjustment component 8 and a second adjustment component 9 are integrally formed at both ends of the handhold post 5. The first adjustment component 8 includes an end head I 81 and an internal hexagonal hole 82. The second adjustment component 9 includes an end head II 91, a square hole II 92, and an external hexagonal block 93.
[0030] The precise fit between the arc groove 4, the rectangular block 6, the handheld column 5, and the square hole I 7 enables stable adjustment of the bolts on the same diving helmet. The arc groove 4 at the top of the connecting rod 3 fits snugly against the outer wall of the handheld column 5 during assembly. The bottom of the arc groove 4 is connected to the rectangular block 6 by an integral molding process, and the top of the rectangular block 6 extends beyond the surface of the connecting rod 3. The extension length is half the depth of the arc groove 4; for example, if the arc groove is 20mm deep, the extension end is 10mm long. This extension section serves as a limiting structure for the handheld column 5, preventing axial movement during underwater operations. The handheld column 5 has a non-slip frosted surface treatment to enhance friction during wet hand operation, ensuring sufficient transmission of operating torque and preventing adjustment deviations due to hand slippage. In actual operation, divers can adjust the force application angle by rotating the handheld column 5 according to the size of the underwater working space: in open areas, the handheld column can be rotated to a straight line with the connecting rod 3 at 180° to obtain the maximum lever arm; in narrow spaces, the handheld column can be folded to an angle of 30°-60° with the connecting rod to avoid collision with the helmet shell. The precise fit between the rectangular block 6 and the square hole I 7 ensures effective force transmission, while the frosted surface improves grip stability, maintaining reliable control even when operating with gloves on.
[0031] The first adjustment component 8, as the core functional end of the diving helmet adjustment wrench, must balance underwater operation precision and tool compatibility in its structural design. The end head I 81 is connected to the end of the handheld column 5 via a one-piece molding process, and its surface has an internal hexagonal hole 82 to avoid the breakage risk caused by a split structure and to allow adjustment of a different type of bolt on the same diving helmet using the internal hexagonal hole 82. If a bolt is not suitable for the socket 1, the first adjustment component 8 will be used. The diver first removes the handheld column 5 from the connecting rod 3. During this process, the rectangular block 6 disengages from the square hole I 7, and simultaneously, the interference fit between the outer wall of the handheld column 5 and the inner wall of the arc groove 4 is released. The diver holds the second adjustment component 9 end of the handheld column 5, aligns the internal hexagonal hole 82 with the corresponding bolt on the same diving helmet, and uses the end head I 81 as a base point to twist the handheld column 5, thereby adjusting the bolt with the corresponding internal hexagonal hole 82.
[0032] The second adjustment component 9, serving as an auxiliary function of the diving helmet adjustment wrench, is structurally designed to form a detachable connection with the connecting rod 3, enabling multi-functional adjustment. The end cap II 91 is connected to the other end of the handheld post 5 via an integrated molding process, avoiding the risk of breakage due to a separate structure. One side of the end cap II 91 has a square hole II 92, and the other side has an external hexagonal block 93, serving two purposes: firstly, the diver holds the handheld post 5 and inserts the square hole II 92 into the extended end of the rectangular block 6, generating better torque force, and then uses it in conjunction with the sleeve 1 to adjust the bolts on the same diving helmet; secondly, the diver can directly use the handheld post 5 and the external hexagonal block 93 on the other side of the end cap II 91 to adjust the internal hexagonal bolts.
[0033] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
