Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses an audible and visual alarm. Referring to fig. 1 and 2, the audible and visual alarm comprises a lamp holder 1, a lamp body 2 and a lamp cap 3 which are sequentially connected from bottom to top. The lamp body 2 is provided with a charging port 4 for charging the electric components of the lamp holder 3, the lamp holder 1 is also fixedly connected with an adsorption piece 5 for fixedly connecting the lamp holder 1 with a wall, and the adsorption piece 5 adopts a magnet. When the magnet is in contact with the wall, the lamp holder 1 is stabilized on the wall by the magnetism of the magnet.

Referring to fig. 1 and 2, a placing groove 6 is formed in the lamp body 2, the placing groove 6 is located at a corner of the lamp body 2, and a rotating member 7 is rotatably connected to one end of the placing groove 6 close to the lamp holder 1. The rotating part 7 comprises a rotating rod 8, a handheld rod 9 and an eccentric wheel 10 for connecting the rotating rod 8 and the handheld rod 9. A hinge rod 12 is fixedly connected to the rotating rod 8, and the hinge rod 12 is inserted into the placing groove 6 and is rotatably connected with the lamp body 2. The rotary connection of the swivelling lever 8 to the lamp body 2 is achieved by rotation of the swivel lever 12. The cam 11 of the eccentric 10 is located on the side of the eccentric 10 remote from the standing groove 6. After the lamp holder 1 is fixed on a wall body or a desktop by a worker, when the lamp holder 1 needs to be taken down from the wall body or the desktop, the worker only needs to hold the handheld rod 9, the handheld rod 9 starts to rotate by taking the axial lead of the hinged rod 12 as the center of a circle, the eccentric wheel 10 is driven to be separated from the placing groove 6 through the rotation of the handheld rod 9, the rubber sleeve 13 is further sleeved on the cam 11 of the eccentric wheel 10, when the cam 11 of the eccentric wheel 10 is in contact with the wall body or the desktop, the hard contact of the cam 11 of the eccentric wheel 10 on the wall body or the desktop can be reduced through the elastic deformation of the rubber sleeve 13, the rubber sleeve 13 has the effects of protecting the wall body or the desktop, and the effect of directly damaging the wall body or the desktop by the cam 11 of the. After the rubber sleeve 13 contacts with a wall body or a desktop, the holding rod 9 continues to rotate, the pressure of the cam 11 of the eccentric wheel 10 on the wall body or the desktop is gradually increased, the force action is mutual, the rebounding force of the cam 11 of the eccentric wheel 10 on the wall body or the desktop is also gradually increased until the rebounding force is greater than the magnetic force between the magnet and the wall body or the desktop, and at the moment, the magnet can be separated from the wall body or the desktop, so that a worker can take the lamp holder 1 off the wall body or the desktop conveniently.

Referring to fig. 2 and 3, the outer side wall of the rubber sleeve 13 is further provided with a rubber bump 14 integrally connected with the rubber sleeve 13, and if the rubber sleeve 13 is deformed so as not to be restored due to an excessive extrusion force, a worker can hold the rubber bump 14 so that the worker can take the rubber sleeve 13 off the cam 11 of the eccentric wheel 10 by applying a force to the rubber sleeve 13, and then sleeve a new rubber sleeve 13 on the cam 11 of the eccentric wheel 10.

Referring to fig. 2 and 3, the two opposite side walls of the hand-held lever 9 are further provided with recessed grooves 15, and two opposite inner side walls of the placement groove 6 are fixedly connected with plastic tabs 16 inserted into the recessed grooves 15. When need not to use and rotate piece 7, the staff can with rotate piece 7 income to standing groove 6 in, the staff rotates through the direction with handheld pole 9 orientation standing groove 6, make handheld pole 9, eccentric wheel 10 and dwang 8 rotate to standing groove 6 in, when handheld pole 9 changes over to standing groove 6 in, handheld pole 9 can be earlier with plastics lug 16 emergence contact towards the one end of lamp body 2, along with the continuation rotation of handheld pole 9, plastics lug 16 takes place the deformation under the extrusion of handheld pole 9, align until undercut 15 and plastics lug 16, plastics lug 16 inserts to undercut 15 in and restores to the original state gradually. The snap-fit of the rotary part 7 is achieved by the cooperation of the plastic tabs 16 with the recessed slots 15. The arc groove 17 that communicates with standing groove 6 is still opened to the one end of the fixedly connected with lamp holder 3 of body 2, because the existence of arc groove 17 for the partial entity of handheld pole 9 is not connected with the cell wall of standing groove 6, and the staff can insert the hand and contact with the partial entity of handheld pole 9 in the arc groove 17 so that pull out handheld pole 9 from standing groove 6 once more.

Referring to fig. 1, a protection block 18 for blocking the charging port 4 is further sleeved on the charging port 4, an elastic band 19 is further fixedly connected to the protection block 18, one end of the elastic band 19 is fixedly connected to the protection block 18, and the other end of the elastic band 19 is fixedly connected to the lamp body 2. When the charger is not required to charge the charging port 4, water stain or dust can be prevented from entering the charging port 4 by blocking the charging port 4 with the protective block 18. And the elastic belt 19 is fixedly connected between the protection block 18 and the lamp body 2, and the elastic belt 19 can also play a role in avoiding the loss of the protection block 18.

The embodiment of the application discloses an audible and visual alarm's implementation principle does: when needs are separated lamp stand 1 and wall body or the table body, only need rotate 7 and rotate, rotate eccentric wheel 10 out standing groove 6, later continue to rotate rotation 7, take place the butt with the cam 11 and the wall body or the table body of eccentric wheel 10, prop up lamp stand 1 through cam 11 so that lamp stand 1 and wall body or the table body takes place to separate, lift up lamp stand 1 so that the staff separates lamp stand 1 and wall body or desktop through rotating 7.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
