[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. With the improvement of people's living standards, now everyone lives in high-rise commercial housing, even up to 28 floors, so elevators are an indispensable means of transportation for daily going up and down stairs.

[0003] In the Chinese utility model patent with publication number CN219469371U, an elevator safety alarm device is disclosed, which includes a mounting plate embedded in the inner wall of the elevator car, and the surface of the mounting plate is respectively provided with a floor case module and a one-button intercom alarm; the surface of the mounting plate is provided with a protective mechanism for protecting the one-button intercom alarm, and the protective mechanism includes a protective frame slidably arranged on the surface of the mounting plate, and strip grooves symmetrically opened on the surface of the mounting plate and located on both sides of the one-button intercom alarm, and the inner wall of one of the strip grooves is fixed with a small motor, and the inner wall of the other strip groove is fixed with a limit rod, and the output end of the small motor is fixed with a lead screw, and the protective mechanism also includes sliders slidably arranged on the inner walls of the two strip grooves. Compared with the prior art, the elevator safety alarm device effectively solves the defects of the existing one-button intercom alarm that lack protection and warning functions by setting a protective mechanism.

[0004] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the above-mentioned device protects the one-button intercom alarm through a protective frame. When the staff needs to use the one-button intercom alarm, they need to press the controller to make the small motor drive the protective frame to move upward. In actual use, the time required for the alarm is long, which is not conducive to reducing the pressure of people trapped in the elevator, and the user experience is poor. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an elevator safety wireless alarm device.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an elevator safety wireless alarm device, including an elevator car, a mounting plate arranged on the elevator car, a floor case module arranged on the mounting plate, and a one-button intercom alarm arranged on the mounting plate, a mounting groove is provided on the side wall of the mounting plate, a telescopic rod is slidably arranged in the mounting groove, a protective cover is fixed on the side wall of the telescopic rod away from the mounting groove, and a limiting component for limiting the protective cover is provided on the mounting plate.

[0007] By adopting the above technical solution, when the elevator fails, the staff needs to seek help from outside. At this time, the staff needs to press the protective cover and slide the protective cover upwards, so that the limit assembly can be automatically opened and the protective cover can be moved upwards, so that the one-button intercom alarm is exposed to the line of sight. At this time, the staff only needs to press the one-button intercom alarm to seek help from outside, thereby reducing the difficulty of operation for the staff.

[0008] Furthermore, the telescopic rod includes a sliding rod arranged in the accommodation groove, a compression spring fixed to the side wall of the sliding rod away from the accommodation groove, and a connecting rod slidably connected to the sliding rod, the other end of the compression spring is fixed on the inner wall of the connecting rod, and the connecting rod is slidably connected to the accommodation groove.

[0010] Furthermore, the limit assembly includes a stop rod fixed on the side wall of the mounting plate, a limit groove is provided on the upper surface of the stop rod, a limit hole is provided on the inner wall away from the mounting plate, and the limit assembly also includes a limit rod fixed on the bottom surface of the vertical part of the protective cover and a limit block arranged on the side wall of the mounting groove away from the limit rod.

[0011] By adopting the above technical solution, when the staff does not need to use the one-button intercom alarm, the staff only needs to press the protective cover and pull the protective cover downward to move the protective cover downward, thereby connecting the limit rod and the limit slot. Afterwards, when the limit rod completely enters the limit slot, the staff only needs to loosen the protective cover to reset the protective cover under the action of the compression spring, thereby connecting the limit block and the limit hole, so that the limit block limits the protective cover, thereby reducing the probability of the one-button intercom alarm being accidentally touched.

[0012] Furthermore, a magnet block is arranged on the upper surface of the connecting rod, and an iron sheet is arranged on the inner top wall of the accommodating groove.

[0013] By adopting the above technical solution, when the protective cover moves to the highest point, the iron sheet gradually approaches the magnet block and is attracted to the magnet block, thereby keeping the protective cover stable, thereby reducing the probability of the protective cover interfering with the operator's operation at this time.

[0014] Furthermore, an inclined surface is provided on the edge where the bottom surface of the limiting block intersects with the side wall away from the accommodating groove.

[0015] By adopting the above technical solution, in actual operation, the staff applies inconsistent force when pressing the protective cover, and the distance the protective cover is compressed is inconsistent. The inclined surface reduces the difficulty of connecting the limit block and the limit hole when the staff moves the protective cover downward, thereby reducing the operating difficulty of the staff and improving the staff's user experience.

[0016] Furthermore, rubber sheets are arranged on three adjacent side walls of the protective cover.

[0017] By adopting the above technical solution, the probability of impurities and the one-button intercom alarm contacting each other is reduced, thereby reducing the probability of the one-button intercom alarm being damaged.

[0018] Furthermore, a signboard for prompting the user to press the protective cover is provided on the side wall of the protective cover.

[0019] By adopting the above technical solution, the probability that the elderly and children cannot correctly press the protective cover when frightened is reduced, which is conducive to reducing the probability of panic among trapped persons.

[0020] Furthermore, a plurality of protrusions for reducing the probability of slipping are arranged on the side walls of the vertical portion of the protective cover.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the elevator breaks down, the staff needs to seek help from outside. At this time, the staff needs to press the protective cover and slide the protective cover upwards, so that the limit assembly can be automatically opened and the protective cover can be moved upwards, so that the one-button intercom alarm is exposed to the line of sight. At this time, the staff only needs to press the one-button intercom alarm to seek help from outside, thereby reducing the difficulty of operation for the staff;

[0023] 2. In the present application, when the protective cover moves to the highest point, the iron sheet gradually approaches the magnet block and is attracted to the magnet block, thereby keeping the protective cover stable, thereby reducing the probability that the protective cover interferes with the operation of the staff at this time;

[0024] 3. In this application, in actual operation, the staff applies inconsistent force when pressing the protective cover, and the distance the protective cover is compressed is inconsistent. The inclined surface reduces the difficulty of connecting the limit block and the limit hole when the staff moves the protective cover downward, thereby reducing the operating difficulty of the staff and improving the staff's user experience.
