Description

Technical Field

[0001] The utility model relates to the field of alarm devices, in particular to a pull-rope type emergency button. Background Art

[0002] The alarm device can be operated by the user in an emergency to trigger an alarm message, which is sent to the backend management system or emergency contacts. The pull-cord alarm device is fixed on the wall, and the pull-cord greatly increases the range of the alarm device being triggered. When the user needs an emergency alarm, such as falling and being unable to stand, the alarm device can be triggered by pulling the cord to send an alarm message.

[0003] The existing pull-cord type emergency alarm device is generally connected to the pull cord through a rocker arm, one end of the rocker arm is hinged, and the other end is facing the case. When the pull cord is pulled, the rocker arm swings around its hinged end, thereby triggering the switch. There is a large moving space inside the structure, and the rocker arm is easy to loosen and dislocate, which eventually causes the key to get stuck and the rocker arm cannot be reset.

[0004] The purpose of the present invention is to design a pull-cord type emergency button in view of the above-mentioned problems in the prior art. Utility Model Content

[0009] A control mainboard is fixedly disposed in the accommodation space;

[0010] A button is fixedly arranged on one side of the control main board, and the triggering stroke of the button is in the vertical direction;

[0011] A button handle is disposed around the button, the movable stroke of the button handle is in the vertical direction, and the button can be pressed when the button handle moves downward;

[0012] A pull cord is connected to the button handle, and the pull cord is used to pull the button handle downward.

[0013] Furthermore, it includes a button mounting seat, which is fixedly arranged on the control main board, the button mounting seat is arranged around the periphery of the button, the button is fixedly installed on the button mounting seat, and the left and right sides of the button mounting seat are provided with linear limit plates that cooperate with the button handle.

[0014] Furthermore, the key handle comprises a key handle cap and a key handle seat, the key cap of the key protrudes above the key mounting seat, the key handle cap is sleeved on the key cap, and the key handle cap is arranged at the upper end of the key handle seat.

[0015] Furthermore, straight portions cooperating with the straight limit plates are provided on the left and right sides of the key handle seat.

[0016] Furthermore, a pull cord winding portion is provided at the bottom of the key handle seat, and the pull cord is wound around the pull cord winding portion.

[0017] Furthermore, the key handle seat is provided with protrusions at the front and rear ends thereof, and the protrusions cooperate with the key main board or the front shell or the rear shell to limit the front and rear positions of the key handle seat.

[0018] Furthermore, the front housing or the rear housing is provided with a vertical clamping groove, and the clamping groove cooperates with the protrusion to limit the moving direction of the key handle seat to the vertical direction.

[0019] Furthermore, the front shell is provided with a front button.

[0020] Furthermore, the front housing is provided with a warning light.

[0021] Therefore, the utility model provides the following effects and / or advantages:

[0022] The utility model changes the structure of the prior art in which one end of the rocker arm is hinged and the other end is directed toward the button, and a button handle is directly arranged around the button. The movable stroke of the button handle is limited to the vertical direction, so that the structure of the pull-cord type alarm device can be realized in a smaller and more compact space. At the same time, the rebound force of the button is used to drive the button handle to reset when the pull cord is released, so that the pull-cord alarm structure can be completed in a smaller and more compact structure.

[0023] The utility model limits the moving direction of the key handle by cooperating with multiple structures such as the protruding part, the linear limiting plate, the linear part, etc., so as to prevent the key handle from swinging in other directions to cause the key to be stuck.

[0024] The utility model can trigger the button by pulling the pull cord when a person falls or the user is inconvenient to press the button. It has the advantages of easy assembly, simple structure and convenient use.

[0025] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by practicing the invention. The purpose and other advantages of the invention are realized and obtained by the structures particularly pointed out in the description and the drawings.
