Description

Technical Field

[0001] The utility model relates to the technical field, and particularly relates to a lightning protection surge protector with an alarm function. Background Art

[0002] A lightning protection surge protector with an alarm function is a very important device. The function of this protector is to limit transient voltage and transfer surge current to protect electrical systems and equipment from surge events. When a spike current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the lightning protection surge protector can conduct and shunt in an extremely short time to avoid damage to other devices in the circuit caused by the surge. The lightning protection surge protector is applicable to power supply systems with alternating current of 50 / 60HZ and a rated voltage of 220V to 380V, and can protect against indirect lightning, direct lightning effects, or other transient overvoltage surges. It meets the requirements of surge protection for residential houses, the tertiary industry, and industrial fields. It has protection modes such as phase-to-phase, phase-to-ground, phase-to-neutral, neutral-to-ground, and their combinations, and can effectively protect electronic devices and systems from lightning and surge damage.

[0003] The inventor found the following problems in the prior art that have not been well solved during the implementation of this solution: This type of protector is generally installed on a rail through screws, and the rail is then installed in an incoming line cabinet and a distribution cabinet through screws. Inside the cabinet, there are other control devices, which are also installed on the rail together with the protector. The control and protection components inside the cabinet are relatively numerous, and the rails are also relatively many. Each component is connected with a wire. Since the screws for connecting each component are installed from the bottom position below, when disassembling, inspecting, or replacing components, the staff needs to insert their fingers under the components and search for the position of the screws. Due to the large number of components and the large number of wires connected to each component, the space left for disassembly and assembly is small. Sometimes, the wires that block the view need to be disassembled and assembled before the targeted protector can be disassembled and assembled, resulting in a cumbersome process and inconvenient operation. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a lightning protection surge protector with an alarm function, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A lightning surge protector with an alarm function comprises a protector body, a guide rail seat is arranged below the protector body, L-shaped guide rail plates are arranged at both ends of the top of the guide rail seat, a plurality of horizontal teeth are equidistantly arranged on the top of the inner wall of the L-shaped guide rail plate, a plurality of vertical teeth are equidistantly arranged on the inner side wall of the L-shaped guide rail plate, a guide plate is arranged at the middle position of the inner top of the protector body, spring rods are fixed at both ends of the side walls on both sides of the guide plate, the end of the spring rod away from the guide plate is connected to the L-shaped seat, a plurality of horizontal teeth are equidistantly arranged on the outer top of the L-shaped seat, a plurality of vertical teeth are equidistantly arranged on the outer side wall of the L-shaped seat, and a traction rod is fixed to the bottom end of the side wall of the L-shaped seat on one side close to the guide plate.

[0011] Preferably, a plurality of pull rods are provided between the two L-shaped seats at both ends of the guide plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The groove at the inner bottom of the protector body is clamped on the outer sides of the two L-shaped guide plates, and the two spring rods on both sides of the guide plate are contracted by the toggle of the traction rod, thereby driving the L-shaped seat to be inserted into the interior between the two L-shaped guide plates, and then the spring rod is extended to drive the L-shaped seat to press against the inner wall of the L-shaped guide plate to form a primary limit, and the secondary limit is achieved through the interlacing engagement of horizontal teeth one and two, and finally the third limit is achieved through the interlacing engagement of vertical teeth one and two.

L-shaped guide rail plates 21 are arranged at both ends of the top of the guide rail seat 2. A plurality of second horizontal teeth 22 are equidistantly arranged at the top end of the inner wall of the L-shaped guide rail plate 21. A plurality of second vertical teeth 23 are equidistantly arranged on the inner side wall of the L-shaped guide rail plate 21. A guide plate 11 is arranged at the middle position of the bottom of the protector body 1. Springs 12 are fixed at both ends of the side walls on both sides of the guide plate 11. The ends of the springs 12 far away from the guide plate 11 are connected with L-shaped seats 13. A plurality of first horizontal teeth 15 are equidistantly arranged on the outer top of the L-shaped seats 13. A plurality of first vertical teeth 14 are equidistantly arranged on the outer side wall of the L-shaped seats 13. Traction rods 17 are fixed at the bottom ends of the side walls of the L-shaped seats 13 close to the guide plate 11.

[0021] Specifically, the ends of the traction rods 17 far away from the L-shaped seats 13 respectively extend to the outside between the L-shaped guide rail plates 21 and the protector body 1, facilitating the adjuster to perform the adjustment traction required for disassembly and assembly of the traction rods 17 in an adjustment manner of left and right positions outside.

[0022] Specifically, the first horizontal teeth 15 are respectively inserted and engaged with the second horizontal teeth 22 with matching positions to form a second limit.
