Description

Technical Field

[0001] This utility model relates to the field of hardware tools technology, specifically a special combination wrench for disassembling a foot-operated flush valve. Background Technology

[0002] When installing or disassembling a foot-operated flushing valve, problems such as rust and scaling are prone to occur due to prolonged contact with water. Furthermore, due to limited installation space, using a traditional adjustable wrench presents the following issues when disassembling the inlet valve core fixing assembly: 1. The inlet valve core fixing component is mostly circular, which makes it easy for traditional wrenches to slip; 2. The water inlet is usually located in a confined space and may be obstructed by surrounding pipes, making it difficult to operate with a traditional wrench; 3. Different models of flushing valves have significantly different inlet diameters (such as ∅20, ∅30, ∅40, etc.), requiring frequent tool changes.

[0003] To address the aforementioned problems, this utility model designs a combination wrench for foot-operated flush valves to improve the disassembly efficiency of foot-operated flush valves. Utility Model Content

[0004] The purpose of this utility model is to provide a special combination wrench for disassembling a foot-operated flush valve, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special combination wrench for disassembling a foot-operated flushing valve, comprising an inlet wrench head assembly, an inlet valve core fixing assembly, an outlet wrench head assembly, and an outlet component. The inlet wrench head assembly includes an inlet wrench head and an inlet wrench head rod. The inlet wrench head includes a push rod, with a connecting ring fixed to the outer wall of one end of the push rod. The outer wall of the connecting ring has an opening groove. The inlet valve core fixing assembly includes a fixing assembly body, with a protrusion fixed to the inner wall of the fixing assembly body. The protrusion is adapted to the opening groove. The handle is inserted into the top rod. The inlet wrench head handle includes an outer rod, which consists of a long rod and a short rod. The inlet wrench head assembly includes at least three wrench heads of different sizes, which are adapted to the inlet valve core fixing assemblies commonly used in foot-operated flushing valves with sizes of ∅20, ∅30, and ∅40. The outlet wrench head assembly includes an outlet wrench head and an outlet wrench head handle. The outlet wrench head includes a baffle plate and a hexagonal positioning block. The hexagonal positioning block is fixed to one end of the baffle plate. One end of the outlet component has an adapter groove, and the hexagonal positioning block is adapted to the adapter groove.

[0006] Preferably, the other end of the top rod has a through hole on its outer wall, and the outer rod is inserted into the through hole. The inlet wrench head rod also includes a blocking member, which is fixed to one end of the outer rod.

[0007] Preferably, the diameter of the perforation is larger than the diameter of the outer rod.

[0008] Preferably, the blocking member is cylindrical.

[0009] Preferably, the outer rod is a bent rod with a bending angle greater than 10 degrees.

[0010] Preferably, the outlet wrench head has an L-shaped design to facilitate rotation of the outlet wrench head.

[0011] Preferably, the inlet wrench head, the inlet wrench head rod, the outlet wrench head, and the outlet wrench head rod are all forged from Cr-V alloy steel and chrome-plated to improve wear resistance and rust prevention.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By designing a dedicated inlet wrench head, the slot in the inlet wrench head matches the protrusion in the inlet valve core fixing assembly, thus solving the problem of slippage during traditional wrench disassembly. Additionally, the outer rod includes both a long and a short section, allowing either the long or short section to be inserted into the top rod during disassembly, depending on the available space at the inlet. This addresses the issue of traditional wrenches being difficult to maneuver due to limited inlet space. Furthermore, the inlet wrench head assembly includes at least several wrench heads of different sizes, each compatible with the commonly used inlet valve core fixing assemblies in foot-operated flush valves of sizes ∅20, ∅30, and ∅40. This allows for selective use of the appropriate wrench head for different flush valve inlets, eliminating the need for frequent tool changes. Attached Figure Description

[0015] 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.

[0016] When installing or disassembling a foot-operated flushing valve, it is prone to rust and scaling due to prolonged contact with water. When it needs to be replaced later, a special combination wrench is required.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a special combination wrench for disassembling a foot-operated flush valve, including an inlet wrench head assembly, an inlet valve core fixing assembly 3, an outlet wrench head assembly, and an outlet component 6. The inlet wrench head assembly includes an inlet wrench head 1 and an inlet wrench head rod 2. The inlet wrench head 1 includes a push rod 101, and a connecting ring 102 is fixed to the outer wall of one end of the push rod 101. An opening groove 103 is formed on the outer wall of the connecting ring 102. The inlet valve core fixing assembly 3 includes a fixing assembly body 301, and a protrusion 302 is fixed to the inner wall of the fixing assembly body 301. The protrusion 302 is adapted to the opening groove 103. The handle 2 is inserted into the top rod 101. The inlet wrench head 2 includes an outer rod 201, which consists of a long rod and a short rod. The inlet wrench head assembly includes at least three wrench heads of different sizes, which are adapted to the inlet valve core fixing assembly 3 commonly used in foot-operated flushing valves with sizes of ∅20, ∅30, and ∅40. The outlet wrench head assembly includes an outlet wrench head 4 and an outlet wrench head 5. The outlet wrench head 4 includes a baffle plate 401 and a hexagonal positioning block 402. The hexagonal positioning block 402 is fixed to one end of the baffle plate 401. One end of the outlet component 6 has an adapter groove, and the hexagonal positioning block 402 is adapted to the adapter groove. The outlet wrench head 5 has an L-shaped design to facilitate the rotation of the outlet wrench head 4.

[0018] It is important to note that by setting up a dedicated inlet wrench head 1, the opening groove 103 in the inlet wrench head 1 is adapted to the protrusion 302 in the inlet valve core fixing assembly 3, thus solving the problem of slippage during the disassembly of traditional wrenches. In addition, the outer rod 201 includes two parts, a long rod and a short rod. In this way, during the disassembly process, the long rod or the short rod can be inserted into the top rod 101 according to the size of the space at the inlet position, thus solving the problem that traditional wrenches are difficult to use due to the narrow space at the inlet. Furthermore, the inlet wrench head assembly includes at least three wrench heads of different sizes, which are adapted to the inlet valve core fixing assemblies 3 commonly used in foot-operated flush valves with sizes of ∅20, ∅30, and ∅40. This allows for the selective use of the corresponding wrench head for different models of flush valve inlets, eliminating the need for frequent tool changes.

[0019] like Figure 2 As shown, the other end of the top rod 101 has a through hole 104 on its outer wall. The outer rod 201 is inserted into the through hole 104. The inlet wrench head rod 2 also includes a blocking member 202, which is fixed to one end of the outer rod 201. The diameter of the through hole 104 is larger than the diameter of the outer rod 201. The blocking member 202 is cylindrical. The outer rod 201 is a bent rod with a bending angle greater than 90 degrees.

[0020] It should be noted that the outer rod 201 is designed as a bent rod, which not only allows for easy switching of the insertion part according to the available space, but also makes it easier for users to grip the outer rod 201 and improves comfort.

[0021] like Figure 1 and Figure 3 As shown, the inlet wrench head 1, the inlet wrench head rod 2, the outlet wrench head 4, and the outlet wrench head rod 5 are all forged from Cr-V alloy steel and chrome-plated to improve wear resistance and rust prevention.

[0022] It should be noted that by forging with Cr-V alloy steel and chrome plating, the overall wear resistance of the combination wrench is improved, allowing for multiple uses and making it less prone to rusting in humid environments.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
