[0002] The pressure gauge of the ring main unit needs to be disassembled and replaced after long-term use. However, due to the limited disassembly and assembly space of the ring main unit and the structure of the conventional wrench, the operator has to operate the wrench with great care to avoid other parts of the ring main unit. Even if other parts of the ring main unit are avoided through complicated operations, it is still difficult to reach the corresponding operating position to disassemble and install the pressure gauge, making the operation very inconvenient.

[0003] There is currently no effective solution to the problem of the inconvenience caused by the difficulty in avoiding obstacles to reach the operating position for the disassembly and assembly of the barometer in related technologies. Summary of the Invention

[0031] Example 1

[0032] Reference Figure 1 This application relates to a wrench for a ring main unit. The wrench includes a wrench head, whose opening engages with the screws of the ring main unit's pressure gauge that need to be removed or installed, thereby enabling the removal and installation of the pressure gauge. A first extension rod is vertically arranged on the wrench head away from its opening. This first rod allows for effective bypassing of other parts of the ring main unit to reach the operating position of the pressure gauge, achieving obstacle avoidance. Furthermore, because the wrench head is perpendicular to the first rod, it is possible to quickly engage the wrench head with the screws at the operating position of the pressure gauge without adjusting the angle of the first rod when bypassing other parts of the unit, making operation very simple. A second driving rod is vertically installed at the tail end of the first rod, which is easy for the operator to hold and operate. When the wrench head is aligned with the screw at the operating position of the ring main unit's pressure gauge, since the second rod is perpendicular to the first rod, rotating the second rod radially will drive the first rod to rotate axially. The first rod will then drive the wrench head to rotate, completing the installation and removal of the screw at the operating position of the ring main unit's pressure gauge. Therefore, during use, the operator does not need to hold the first rod awkwardly, but can operate through the second rod, which is very convenient and effectively avoids situations where operation is difficult or inconvenient.

[0033] In this embodiment, preferably, the tail end of the second rod is provided with a spherical body; the spherical body can serve as a force-bearing point when the operator rotates the second rod by hand, thereby protecting the operator's hand.

[0034] Example 2

[0035] Based on Embodiment 1, the wrench head and the first rod are detachably connected in this embodiment. The wrench head and the first rod are detachably connected, which can be adapted to ring main units with different operating spaces by disassembly or installation. For example, the two can be disassembled and only the wrench head is used for operation, which is suitable for ring main units without obstacles; or the two can be assembled and the first rod is used in conjunction with the wrench head for operation, which is suitable for ring main units with large obstacles.

[0036] A first connector is vertically disposed on the wrench head away from its opening. The first connector at the head of the first rod is detachably snapped into the first snap-fit ​​hole of the first connector. Specifically, in this embodiment, the first rod and the wrench head are detachably connected by the first connector and the first snap-fit ​​hole of the second connector, which facilitates quick and easy assembly and disassembly.

[0037] Reference Figure 3 In this embodiment, preferably, the first snap-fit ​​hole is a regular polygon structure, and the first set of connectors is a regular polygon body that matches the first snap-fit ​​hole. The regular polygon can effectively snap the first snap-fit ​​hole and the first set of connectors together. It can also be assembled by rotating at different angles according to the needs of the scenario, which facilitates personnel operation and can be adapted to different operating spaces to prevent bumping into other parts in the ring network cabinet.

[0038] Example 3

[0039] Based on Embodiment 1, the wrench head and the first rod are detachably connected in this embodiment. The wrench head and the first rod are detachably connected, which can be adapted to ring main units with different operating spaces by disassembly or installation. For example, the two can be disassembled and only the wrench head is used for operation, which is suitable for ring main units without obstacles; or the two can be assembled and the first rod is used in conjunction with the wrench head for operation, which is suitable for ring main units with large obstacles.

[0040] A first connector is vertically disposed on the wrench head away from its opening. The first connector at the head of the first rod is detachably snapped into the first snap-fit ​​hole of the first connector. Specifically, in this embodiment, the first rod and the wrench head are detachably connected by the first connector and the first snap-fit ​​hole of the first connector, which facilitates quick and easy assembly and disassembly.

[0041] Reference Figure 5In this embodiment, preferably, the first snap-fit ​​hole is a regular polygonal hole, and a washer with an outer ring of a regular polygonal hole is snapped into the regular polygonal hole. The inner ring of the washer has a regular polygonal structure. The regular polygonal hole can hold the washer with an outer ring that also has a regular polygonal structure. Since the inner ring of the washer has a regular polygonal structure, it can hold the first set of connectors. It can also be assembled at different angles according to the needs of the scenario, which facilitates personnel operation and can be adapted to different operating spaces to prevent bumping into other components in the ring main unit. In addition, since the first snap-fit ​​hole and the first snap-fit ​​connector are directly used to cooperate, the inner wall of the first snap-fit ​​hole is easily worn after repeated disassembly and assembly, which will cause the snap-fit ​​to loosen and affect the use. To avoid this situation, a washer is used between the first snap-fit ​​hole and the first snap-fit ​​connector. When the washer is worn, a new washer can be directly replaced, thereby extending the service life.

[0042] Example 4

[0043] Based on Embodiment 1, the first and second rods are also connected in a detachable manner, which can be adapted to ring main units with different operating spaces by disassembly or installation; for example, the second rod can be disassembled and only the first rod can be used with a wrench head for operation, which is suitable for ring main units with large obstacles; or the second rod can be assembled and used with the first rod and a wrench head for operation, which is suitable for ring main units with even greater obstacles and easier to be bumped.

[0044] The first rod has a second connector at its tail end, and the second connector at the head end of the second rod is detachably connected to the second snap-fit ​​hole of the first connector. The second connector is perpendicular to the second rod. Specifically, in this embodiment, the first rod and the second rod are detachably connected by the second connector and the second snap-fit ​​hole of the second connector, facilitating quick and easy assembly and disassembly. It is worth noting that the second connector is perpendicular to the second rod, ensuring that when the second rod rotates radially, it ultimately drives the wrench head to rotate and tighten the screw.

[0045] Reference Figure 4 In this embodiment, preferably, the shape of the second snap-fit ​​hole is a regular polygon structure, and the second socket is a regular polygon body that matches the second snap-fit ​​hole; the regular polygon can effectively snap the second snap-fit ​​hole and the second socket, and can also be rotated at different angles according to the needs of the scenario during assembly, so as to facilitate personnel operation and adapt to different operating spaces to prevent bumping into other parts in the ring network cabinet.

[0050] The second snap-fit ​​hole is a threaded hole, and the second sleeve is a threaded head that matches the threaded hole; through the cooperation of the threaded hole and the threaded head, the first rod and the second rod are fixed together, and the connection is reliable and not easy to loosen.
