Description

Technical Field

[0001] The utility model relates to the field of escape locks, in particular to an electronic monitoring structure of a pressure rod of a downward-pressing escape lock. Background Art

[0002] Generally speaking, buildings are equipped with fire safety doors so that people can unlock them and escape through the fire safety doors in the event of a fire. Existing fire safety door locks are mainly divided into single-point locks, double-point locks, three-point locks, vertical single-point locks, embedded lock boxes, and embedded vertical upper and lower lock point driving structures according to the installation form. The embedded lock box is set inside the fire safety door, and its lock tongue is horizontally and rotary telescopic; the embedded vertical upper and lower lock point driving structure is also set inside the fire safety door, but its lock rod is vertically movable; and the single-point lock, double-point lock, three-point lock, and vertical single-point lock are set on the outside of the fire safety door.

[0003] The prior art includes a utility model with a publication number of CN211287014U, which discloses a push-down universal lock driving structure. The patent adopts a door outer space of a door panel and has a horizontal channel and a vertical channel for universal assembly in a single-point lock, a double-point lock, a three-point lock, a vertical single-point lock, an embedded lock box or an embedded vertical upper and lower lock point driving structure, and includes a base, a push-down handle assembly and a driving member. The base is set on the door panel and has a through hole. The push-down handle assembly can be pivotally connected to the base. The driving member is connected to the push-down handle assembly and is arranged in conjunction with a driven assembly in a single-point lock, a two-point lock, a three-point lock, a vertical single-point lock, an embedded lock box or an embedded vertical upper and lower lock point driving structure, and is operated to drive the driven assembly, solving the problem that the lock driving structure PA1 and the lock driving structure PA1a are not universal. As shown in the figure, the lock driving structure PA1a cannot allow the lock tongue PA3 to pass horizontally, and the lock driving structure PA1 cannot allow the lock rod PA3a to pass vertically, resulting in different locks needing to be matched with different lock driving structures, resulting in expensive manufacturing costs and cumbersome replacement steps. Therefore, the existing lock driving structure still has the problem of solving the space problem.

[0004] The inventor believes that the following technical defects exist: the existing escape door locks do not have a monitoring function and cannot monitor whether the escape door is open or closed, which will reduce the safety of the escape door locks and reduce the scope of application of the escape door locks.

[0005] Therefore, it is necessary to provide a new electronic monitoring structure of a downward-pressing escape lock pressure rod to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an electronic monitoring structure for a downward-pressing escape lock pressure rod.

[0007] The utility model provides a downward-pressed escape lock pressure rod electronic monitoring structure, comprising two bases, a fixing base is installed on one side of the base, a lock tongue is installed on one of the two fixing bases, a support is installed on the side of the fixing base away from the base, a handle is installed inside the support, a mounting frame is installed on one end of the fixing base away from the base and fixed with a plurality of first screws, a micro switch is installed on one side of the mounting frame, a spring piece for controlling opening and closing is installed on one side of the micro switch, the micro switch is fixed with a plurality of second screws, a driving member is installed on one end of the handle close to the support, the driving member is located inside the fixing base, a driving device is installed inside the fixing base, the driving device drives the driving device, and the driving device drives the lock tongue to perform unlocking and locking actions, a pressure rod is installed on one end of the handle close to the support, and a shell is installed on the side of the base close to the fixing base.

[0008] Preferably, three interfaces are provided on one side of the micro switch, which are respectively a first interface, a second interface and a third interface. The first interface is specifically a COM interface, the second interface is specifically a NO interface, and the third interface is specifically an NC interface. The COM interface is a common terminal, the NO interface is a normally open terminal, and the NC interface is a normally closed terminal.

[0009] Preferably, the micro switch spring is pressed to trigger the disconnection of COM+NC, and the monitoring door panel (14) is now in a locked state.

[0010] Preferably, the micro switch spring is released, triggering the disconnection of COM+NO, and the monitoring door panel (14) is now in an open state.

[0011] Compared with the related art, the electronic monitoring structure of the downward-pressing escape lock pressure rod provided by the utility model has the following beneficial effects:

[0012] In the utility model, when the door is locked, the upper lock tongue and the lower lock tongue, the upper lock buckle and the lower lock buckle are all buckled, and the micro switch spring piece mounted on the linkage plate is pressed due to contact with the driving member. If the user connects the wires COM and NO of the micro switch to a green light source, and connects the wires COM and NC of the micro switch to a red light source, when the door is closed, the micro switch spring piece is pressed and triggers COM+NC to disconnect, and the monitoring door plate (14) is in a locked state at this time, and a green light will be turned on to monitor whether the door is locked. When the escape lock pressure rod is pressed, the structure linkage drives the upper lock tongue and the lower lock tongue, the upper lock buckle and the lower lock buckle to disengage, and the micro switch spring piece mounted on the linkage plate is released due to being away from the driving member, thereby triggering COM+NC to conduct, and a red light will be turned on to monitor whether the door is opened. By setting the overall structure, the effect of conveniently monitoring the switch state of the escape lock is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

The monitoring door panel 14 is in a locked state at this time, and the green light will be on at this time to monitor whether the door is in a locked state. When the escape lock pressure rod 7 is pressed, the structure drives the upper lock tongue 9 and the lower lock tongue 9, and the upper lock buckle and the lower lock buckle to disengage. At this time, the spring piece of the micro switch 2 mounted on the linkage plate is released because it is away from the driving member, thereby triggering COM+NC to be turned on. At this time, a red light will be on to monitor whether the door is opened. By setting the overall structure, the effect of conveniently monitoring the switch status of the escape lock is achieved.
