Description

Technical Field

[0001] The utility model relates to the technical field of fire alarm, in particular to an audible and visual alarm with a protective structure. Background Art

[0002] The sound and light alarm, also known as the sound and light alarm, is an alarm signal device used in dangerous places. It sends out both sound and light alarm signals at the same time to meet customers' special requirements for alarm loudness and installation location. This alarm is usually installed in industrial environments, such as iron and steel metallurgy, telecommunications towers, lifting machinery, construction machinery, ports and docks, transportation, wind power generation, ocean-going ships and other industries. When an emergency such as an accident or fire occurs at the production site, the sound and light alarm will send out sound and light alarm signals to complete the alarm purpose.

[0003] At present, in the prior art, a Chinese patent with announcement number CN207601979U discloses a sound and light alarm, which is connected to a base through a plug-in block on a support frame to fix the base on the support frame, thereby facilitating the installation of the alarm. However, in actual use, the device may fail because the alarm is exposed to the external environment for a long time and no protective measures can be taken. In view of this, we propose a sound and light alarm with a protective structure. Utility Model Content

[0006] A clearance cavity, wherein the inner wall of the connecting column is provided with a clearance cavity;

[0007] A fixed block is fixedly connected in the give way cavity.

[0008] Preferably, a sliding groove is provided on the outer wall of the fixed block, and a sliding plate is slidably connected in the sliding groove. The outer wall of the sliding plate is designed with a notch, which is from shallow to deep, so as to facilitate the lifting and lowering activities of subsequent components when sliding.

[0009] Preferably, one end of the sliding plate passing through the outer wall of the connecting column is fixedly connected with a rotating handle, and the upper part of the outer wall of the connecting column is fixedly connected with a movable block, which moves in the yield cavity and adjusts the height in real time according to the movement of the sliding plate.

The return spring assists in resetting the movable block when its height is adjusted, and the protective shell is provided to prevent the movable block from colliding with the yield cavity when it moves.

[0011] Preferably, the outer wall of the protective shell is fixedly connected with a hinge rod, and one end of the hinge rod away from the outer wall of the protective shell is hinged to the clamping block, and the movable block drives the movement of the protective shell to adjust the angle of the hinge rod.

[0012] Preferably, a positioning rod is fixedly connected in the yield cavity, and the positioning rod is arranged in an arc groove opened in the clamping block. The hinged rod drives the angle deflection of the clamping block. During the movement of the clamping block, the positioning of the positioning rod prevents the clamping block from being displaced when it rotates.

[0013] The utility model provides an audible and visual alarm with a protective structure, which has the following beneficial effects:

[0014] (1) The sound and light alarm with a protective structure is provided with a clamping device. By stretching and rotating the handle, the sliding plate is stretched. When stretched to the deepest part of the notch of the sliding plate, the sliding plate drives the height adjustment of the movable block. The protective shell on the outer wall of the movable block prevents the movable block from colliding with the clearance cavity when it moves. The movable block drives the movement of the protective shell, so that the angle of the hinged rod is adjusted. The hinged rod drives the angle of the clamping block to deflect. During the movement of the clamping block, the positioning rod is positioned to prevent the clamping block from being displaced when it rotates. After the angle of the clamping block is deflected, the clamping block clamps the edge of the protective cover to complete the protective measures and achieve the protection effect of the sound and light alarm.

[0015] (2) The sound and light alarm with a protective structure is provided with a sliding plate, the outer wall of which is designed with a notch, which is from shallow to deep, so as to facilitate the lifting and lowering activities of subsequent components when sliding.

A fixed block 62 is fixedly connected in the clearance cavity 61, and a sliding groove 63 is provided on the outer wall of the fixed block 62, and a sliding plate 64 is slidably connected in the sliding groove 63. The outer wall of the sliding plate 64 is designed with a notch, and the notch is from shallow to deep, which is convenient for driving the lifting and lowering activities of the subsequent components when sliding. The sliding plate 64 passes through the outer wall of the connecting column 2. One end is fixedly connected with a rotating handle 65, and a movable block 66 is fixedly connected to the upper part of the outer wall of the connecting column 2. The movable block 66 moves in the clearance cavity 61, and the height is adjusted in real time by the movement of the sliding plate 64. The outer wall of the movable block 66 is sleeved There is a reset spring 67, and the movable block 66 is elastically connected to the protective shell 68 through the reset spring 67. When the height of the movable block 66 is adjusted, the reset spring 67 assists its reset. The protective shell 68 is set to prevent the movable block 66 from colliding with the yield cavity 61 when it moves. The outer wall of the protective shell 68 is fixedly connected with a hinge rod 69, and the end of the hinge rod 69 away from the outer wall of the protective shell 68 is hinged to the clamping block 610.
