Description

Technical Field

[0001] This utility model relates to the field of valve operation technology, specifically a folding handle type portable valve operating mechanism. Background Technology

[0002] Valves are widely used in numerous fields such as industrial production, building water supply and drainage, and HVAC, serving as key devices for controlling fluid flow and regulating flow. Currently, the most common valve operation methods are traditional handwheels or long-handled wrenches. With traditional handwheel operation, when the space around the valve is confined, operators often lack sufficient arm space to rotate the valve, leading to operational difficulties and even preventing the valve from being opened or closed properly. Furthermore, for some large valves, handwheel operation requires significant force, which can easily cause operator fatigue over time. While long-handled wrenches increase the lever arm and reduce the required force to some extent, their fixed length occupies considerable space during transport and storage, making them inconvenient for transportation and storage. The poor portability of long-handled wrenches is particularly pronounced in scenarios requiring frequent changes in operating locations.

[0003] To address the aforementioned issues, a portable valve operating mechanism with a folding handle is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a folding handle type portable valve operating mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a folding handle type portable valve operating mechanism, including a connecting seat, a mounting bracket fixedly disposed at the middle of the top of the connecting seat, a mounting block engaged inside the mounting bracket, a first support rod fixedly connected to the middle of the top of the mounting block, a second support rod disposed at the top of the first support rod, a hinge disposed at the connection between the first support rod and the second support rod, a mounting bracket engaged at the top of the second support rod, an operating handle fixedly disposed at the top of the mounting bracket, a fixing block fixedly disposed at the top of one side of the first support rod, a connecting block fixedly disposed at the bottom of one side of the second support rod, a threaded rod threaded in the middle of the connecting block, and a knob fixedly disposed at the top of the threaded rod.

This significantly reduces its size when not in operation, making it easy to carry and store. Operators can easily place it in a tool bag or carry it with them, meeting the needs of valve operation in different locations, especially suitable for scenarios requiring frequent relocation. A locking mechanism consisting of a threaded rod, a fixing block, and a connecting block securely locks the unfolded second support rod, preventing accidental folding and ensuring the safety and stability of valve operation. The engagement of the mounting bracket and the mounting block, along with the double-threaded fixing bolts, ensures a strong and reliable connection between the first support rod and the connecting seat, capable of withstanding large operating torques without loosening or detaching during operation.

[0007] Preferably, a second threaded hole is provided at the connection between the connecting block and the threaded rod, and the second threaded hole is threadedly connected to the threaded rod.

[0008] Preferably, the bottom end of the connector has a connecting hole.

[0009] Preferably, a connecting block is fixedly provided at the connection between the mounting base and the mounting block, and a connecting slot is provided at the connection between the mounting block and the mounting base, wherein the connecting block and the connecting slot are engaged and connected.

A second threaded hole 12 is opened at the connection between the connecting block 10 and the threaded rod 13, and the second threaded hole 12 is threadedly connected to the threaded rod 13. A connecting hole 20 is opened at the bottom of the connecting seat 1. The operating mechanism adopts a folding design, and the second support rod 5 can be flexibly rotated and folded around the hinge 6. The volume is greatly reduced when not in operation, making it convenient to carry and store. Operators can easily put it into a tool bag or carry it with them to meet the needs of valve operation in different locations. It is especially suitable for scenarios that require frequent relocation. The locking mechanism composed of threaded rod 13, fixing block 9 and connecting block 10 can firmly lock the unfolded second support rod 5 to prevent accidental folding and ensure the safety and stability of valve operation. The engagement connection between the mounting seat 2 and the mounting block 3 and the double thread fixing of the fixing bolt 16 ensure that the connection between the first support rod 4 and the connecting seat 1 is firm and reliable, and can withstand a large operating torque without loosening or falling off during operation.

[0018] In use, the embodiment of this application has the following: a second support rod 5 is provided at the top of the first support rod 4, and a hinge 6 is provided at the connection between the first support rod 4 and the second support rod 5. The hinge 6 is made of high-quality stainless steel, which has high strength and wear resistance, and can ensure that the second support rod 5 can rotate flexibly on the first support rod 4, so as to realize the folding function of the operating mechanism. When valve operation is required, the second support rod 5 is rotated upwards around the hinge 6 to unfold the operating mechanism, putting it into working condition. After operation, the second support rod 5 is rotated downwards and folded to reduce the size of the operating mechanism for easy storage and carrying. To ensure a stable unfolded state between the second support rod 5 and the first support rod 4 during operation, and to prevent the second support rod 5 from folding due to accidental collisions or vibrations, a fixing block 9 is fixedly installed at the top of one side of the first support rod 4, and a connecting block 10 is fixedly installed at the bottom of one side of the second support rod 5.
