Problems solved by technology

[0004] The alarm device is usually installed on the wall through the installation bracket, and the installation bracket and the alarm device are usually installed and fixed by bolts. The bolt penetration step is relatively cumbersome, which is inconvenient for the alarm device to be installed quickly, resulting in that the alarm device cannot be automatically fitted and fixed during installation.

Embodiment 1

[0031] Embodiment 1: An alarm device that can cut off the power supply based on voltage control equipment, including an alarm 1, an air switch 101 is installed on the back of the alarm 1, a bracket 103 is installed through the back of the alarm 1, and a through frame is penetrated inside the bracket 103 102, the inner side of the bracket 103 is provided with a limit mechanism that can be automatically clamped;

[0032] Among them: the alarm 1 is electrically connected to the power supply through the power cord, the alarm 1 is connected to the control equipment, the air switch 101 is connected to the control equipment through the alarm 1, the air switch 101 is convenient for the alarm to cut off the power as a whole, and the bracket 103 is vertically corresponding Setting, the bracket 103 is set in a concave shape, and the inside of the bracket 103 is set in a hollow shape. When the through frame 102 is embedded in the inside of the bracket 103, the limit mechanism automatically...

Embodiment 2

[0043] Embodiment 2: with reference to instruction manual Figure 4 with 7 It can be seen that the difference between Embodiment 2 and Embodiment 1 is that the limit mechanism includes a connecting rod 4, a tooth piece 401, a swing rod 5, a gear 501 and a bump 502, the connecting rod 4 is installed on one side of the airbag 2, and the tooth The piece 401 is arranged at both ends of the connecting rod 4, the gear 501 is rotated and fitted on the outside of the tooth piece 401, the swing rod 5 swings on one end of the gear 501, and the protrusion 502 swings on one end of the swing rod 5;

[0044] The swing rod 5 is arranged in a curved shape. When the bump 502 is at rest, the bump 502 is movably nested inside the bracket 103. The bump 502 is set in a concave shape. The swing rod 5 and the gear 401 are matched to the upper and lower ends of the connecting rod 4;

[0045] Wherein: the airbag 2 drives the connecting rod 4 to slide horizontally, the connecting rod 4 drives the gear...

Abstract

The invention provides an alarm device that can cut off the power supply based on voltage control equipment, including an alarm device, an air switch is installed on the back of the alarm device, a bracket is installed on the back of the alarm device, a penetrating frame is installed inside the bracket, and an adjustable Automatic clamping limit mechanism, the limit mechanism includes airbag, adsorption layer, negative pressure valve, sleeve, telescopic rod, shaft and baffle, the airbag is embedded in the bracket, the adsorption layer is embedded in the inner side of the airbag, and the airbag drives the connecting rod Sliding horizontally, the connecting rod drives the gear to swing through the tooth piece, and at the same time, the gears at the upper and lower ends of the tooth piece swing at an angle at the same time, and the gear quickly drives the bump to swing at an angle through the swing rod, and one side of the bump closely fits the outside of the through frame , so that the limit mechanism uses the extrusion of the through-frame to the airbag to automatically limit the outer side of the through-frame tightly, and a relative extrusion limit is formed between the through-frame and the bump, so that the bracket and the through-frame can be automatically fitted and fastened Effect.

Description

technical field [0001] The invention relates to the technical field of voltage control, in particular to an alarm device capable of cutting off power supply of equipment based on voltage control. Background technique [0002] The electrical control system is generally called the secondary control loop of electrical equipment. Different equipment has different control loops, and the control methods of high-voltage electrical equipment and low-voltage electrical equipment are different. The voltage control system is controlled by the control equipment, and the control equipment is in the During use, an alarm device is required to give an early warning to the control equipment to avoid failure to alarm when the voltage is too high; [0003] Aiming at the technical problems of the above-mentioned alarm device, it is found through retrieval that there is a patent No. CN202010672919.0, a voltage-sensitive alarm device and its alarm method, the voltage-sensitive alarm device and it...
