Description

Technical Field

[0001] This utility model relates to the field of tools for operating sea valves, and in particular to a special ratchet wrench for sea valves. Background Technology

[0002] A sea valve is a valve that draws seawater in from outside the ship's hull; also known as a sea valve box or seabed valve, it is part of the ship's seawater system. It can be opened or closed manually or hydraulically. A sea valve ratchet wrench is a specialized tool used for routine manual operation or in emergency manual operation in case of hydraulic failure. Due to the special structure of the sea valve, the ratchet wrench must be repeatedly pushed to complete one opening or closing operation. When manually opening or closing the sea valve, the valve stem will spring back with the wrench's return stroke due to the hydraulic press, and the force of this springback is considerable. During operation, the ratchet wrench is quickly returned to a speed greater than the valve stem's springback speed before being quickly pushed back to overcome this. This requires the operator to possess certain skills and strength; otherwise, there is a safety hazard and risk of injury from the ratchet wrench handle springing back. Utility Model Content

[0003] In view of the deficiencies in the prior art, the main objective of this utility model is to provide a special ratchet wrench for sea valves to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A special ratchet wrench for a sea valve includes: a ratchet stop portion and a handle; the ratchet stop portion includes a ratchet stop assembly and a ratchet assembly; the ratchet stop assembly includes a ratchet, a ratchet stop reversing block, a ratchet stop body, a fixing pin I, and a positioning hole; the ratchet stop reversing block is connected to the ratchet stop body via the fixing pin I, and is used to limit the rotation direction of the ratchet; the positioning hole is disposed on both sides of the ratchet stop body; the ratchet assembly includes a ratchet body, a bolt, a ratchet stop reversing block, and a fixing pin II, the ratchet stop reversing block is connected to the ratchet body via the fixing pin II, and is used to adjust the rotation direction of the ratchet body; the ratchet assembly and the ratchet stop assembly are connected by the bolt; the ratchet is disposed in the cavity formed after the ratchet assembly and the ratchet stop assembly are connected; the handle is fixedly connected to the ratchet body.

[0006] Furthermore, the ratchet is machined into a through-hole structure, and the through-hole structure is polygonal.

[0007] Furthermore, the through-hole structure forms an inner 12-angle.

[0008] Compared with the prior art, this utility model provides a special ratchet wrench for sea valves. The beneficial effect is that the ratchet wrench for sea valves, by setting a backstop component, prevents the ratchet wrench handle from rebounding in the opposite direction when opening or closing the sea valve, thus overcoming the safety risks and hidden dangers of rebound injury.

[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:

[0019] like Figure 1 and Figure 2 As shown, a special ratchet wrench for a sea valve includes: a ratchet stop (1) and a handle (2).

[0020] like Figure 3-7 As shown, the anti-reverse ratchet part (1) includes an anti-reverse assembly (10) and a ratchet assembly (11); the anti-reverse assembly (10) includes a ratchet (101), an anti-reverse reversing block (102), an anti-reverse ratchet body (103), a fixing pin I (104), and a positioning hole (105); the anti-reverse reversing block (102) is connected to the anti-reverse ratchet body (103) through the fixing pin I (104) to limit the rotation direction of the ratchet (101); the positioning hole (105) is provided on both sides of the anti-reverse ratchet body (103).

[0021] When using this ratchet wrench, insert the positioning hole (105) into the two fixed posts of the sea valve to be rotated, so that the anti-reverse ratchet body (103) cannot rotate. At the same time, move the anti-reverse reversing block (102) to prevent the ratchet (101) from rebounding in the opposite direction, thus achieving the anti-reverse function. The ratchet assembly (11) includes a ratchet body (111), a bolt (112), a ratchet reversing block (113), and a fixing pin II (114). The ratchet reversing block (113) is connected to the ratchet body (111) through the fixing pin II (114) and is used to adjust the direction of the ratchet body (111) to open or close the sea valve. The ratchet assembly (11) and the anti-reverse assembly (10) are connected by the bolt (112); the ratchet (101) is set in the cavity formed after the ratchet assembly (11) and the anti-reverse assembly (10) are connected.

[0022] The handle (2) is fixedly connected to the ratchet body (111).

[0023] Specifically, the ratchet (101) is machined into a through-hole structure, and the through-hole structure is polygonal.

[0024] Specifically, the through-hole structure forms an inner 12-angle. Since the valve stem of a sea valve is generally hexagonal on the outside, using an inner 12-angle structure makes it easier to insert a ratchet wrench into the valve stem of the sea valve.
