Description

TECHNICAL FIELD

[0001] The utility model relates to fire alarm device technical field, specifically is a prevent false touch's fire alarm device. BACKGROUND

[0002] Fire alarm device is the key component in the fire automatic alarm system, is used for receiving, display and transmission fire alarm signal, and can send control signal and have other auxiliary function, its usually through button structure trigger work, carry out alarm work.

[0003] The utility model of a kind of prevent false touch's fire alarm device is disclosed in the utility model No.

[0004] In the above structure, since the limiting structure of trigger button is arranged in the alarm, when it fails or is damaged, it can hinder the rotation of trigger button to some extent, so that the limitation of trigger button cannot be released, so that personnel cannot press the button to make the alarm work. Because the limiting structure is arranged inside, it cannot be repaired or removed in time, so that the alarm cannot be used and the transmission of the alarm signal is delayed. Therefore, a fire alarm device that prevents false touch is proposed to solve the above problems. SUMMARY

[0005] The technical problem to be solved by the utility model is to provide a fire alarm device that prevents false touch. The alarm button of the alarm body is shielded by the false touch prevention baffle, which prevents false touch. When an alarm is needed, press the buckle to make it pop up. The false touch prevention baffle will completely pop up under the action of the pop-up hinge shaft, making it easy to press the alarm button. Based on the above structure, since the entire false touch prevention structure is arranged on the outside, it can be easily repaired or removed when damaged, so that personnel can press the button without affecting the alarm. In particular, the front frame for installing the false touch prevention structure can be detachably installed on the alarm body. When the false touch prevention structure is completely damaged and cannot be repaired, the entire false touch prevention structure can be removed by directly removing the front frame, making it easy for personnel to normally use the alarm body or replace the false touch prevention structure. This solves the technical problem of the prior art that it is difficult to conveniently and simply repair or quickly remove the false touch prevention structure when it is damaged, which causes the alarm to be unable to be used immediately and delays the transmission of the alarm signal.

[0006] The technical scheme adopted by the embodiment of the application to solve the technical problem is:

[0007] The fire alarm device capable of preventing mistaken touch comprises an alarm body, a rear mounting frame fixedly sleeved on the alarm body, a front frame clamped on the front side of the alarm body, a pop-up hinged shaft arranged on the left side of the front frame and having a touch-proof baffle rotatably connected thereto, and a clamping member arranged on the right side of the front frame and used for clamping and fixing the end of the touch-proof baffle. When alarm is needed, the clamping member is pressed to make it pop up, and the touch-proof baffle is completely popped up under the action of the pop-up hinged shaft, so that the alarm button can be pressed conveniently. Based on the above structure, since the whole touch-proof structure is arranged on the outside, the touch-proof structure can be conveniently repaired or removed when it is damaged, and thus the pressing of the button by personnel is not affected.

[0008] The alarm body is provided with clamping grooves on both sides, the front frame is in a C shape, the inner wall of the front frame is provided with clamping edges corresponding in size to the clamping grooves, and the outer surface of the clamping edges is provided with a plurality of anti-skid convex patterns. When the touch-proof structure is completely damaged and cannot be repaired, the whole touch-proof structure can be removed by directly removing the front frame, so that the alarm body can be normally used by personnel or the touch-proof structure can be replaced.

[0009] In a possible implementation manner, the pop-up hinged shaft comprises a first hinged seat, an end connecting plate is fixedly arranged at one end of the touch-proof baffle close to the first hinged seat, and the end connecting plate is rotatably connected to the first hinged seat through a rotating shaft. The above structure can realize the rotatable connection between the touch-proof baffle and the pop-up hinged shaft, and provide a necessary structural basis for the rotation opening and unblocking of the touch-proof baffle.

[0010] In a possible implementation manner, a connecting plate is fixedly arranged on the first hinged seat and adhered to the front frame. This kind of structure can improve the tightness of the connection between the first hinged seat and the front frame. In addition, a reset torsional spring is sleeved on both ends of the rotating shaft, and the two ends of the reset torsional spring are fixedly connected to the end of the rotating shaft and the first hinged seat, respectively. When the free end of the touch-proof baffle lacks constraint, the reset torsional spring can release the torque to drive the touch-proof baffle to rotate and open, so that the alarm button can be directly pressed by personnel.

[0011] In a possible implementation manner, the clamping member comprises a second hinged seat, a rotating connecting plate is rotatably installed on the second hinged seat, a clamping plate is fixedly connected to the end of the rotating connecting plate, and the touch-proof baffle is provided with a clamping groove corresponding to the clamping plate close to the second hinged seat. In a normal state, the clamping plate is buckled in the clamping groove, so as to constrain the free end of the touch-proof baffle, and the touch-proof baffle can block the alarm button to play a role in preventing mistaken touch.

[0012] In a possible implementation, the rear end of the rotating connecting plate is fixedly connected with a pressing piece, the pressing piece is bent to extend to the outside, and the pressing piece can facilitate a user to control the rotation of the rotating connecting plate to realize the buckling and separation between the buckling plate and the buckling groove.

[0013] In a possible implementation, the rear mounting frame is fixedly provided with wing plates on both sides, and a plurality of through mounting holes are formed in the wing plates. The above structure provides a necessary structural basis for the fixed installation of the overall structure.

[0014] In a possible implementation, a plurality of threaded holes are formed in the alarm body, and a through hole communicated with the threaded holes is formed in the front frame. The front frame and the alarm body are fixedly connected through the bolt connecting piece. The above structure can provide a constraint effect, so that the front frame cannot slide along the alarm body, and the front frame is prevented from falling off the alarm body during normal use.

[0015] In a possible implementation, a rubber contact strip is attached to the right side of the front frame. The rubber contact strip is an elastic hollow rubber strip. When the anti-mis-touch baffle is closed, the rubber contact strip is deformed by being pressed, and the rubber contact strip applies a reaction force to the anti-mis-touch baffle, so that the anti-mis-touch baffle can be in close contact with the buckling plate, and the fixing effect of the buckling plate on the anti-mis-touch baffle is improved.

[0016] In summary, the utility model has the following beneficial technical effects:

[0017] The fire alarm device shields the alarm button of the alarm body through the anti-mis-touch baffle, prevents mis-touch, and when alarm is needed, the buckling piece is pressed to be raised, the anti-mis-touch baffle is completely opened under the action of the elastic hinge shaft, the alarm button is pressed, and based on the above structure, since the anti-mis-touch structure is arranged on the outside, the anti-mis-touch structure can be easily repaired or removed when damaged, and thus the personnel pressing the button is not affected.

[0018] In particular, the front frame for installing the anti-mis-touch structure is detachably mounted on the alarm body. When the anti-mis-touch structure is completely damaged and cannot be repaired, the front frame is directly removed to remove the entire anti-mis-touch structure, and the personnel can normally use the alarm body or replace the anti-mis-touch structure.
