[0001] The utility model relates to the field of elevator wireless intercom power supply, in particular to an elevator wireless intercom emergency power supply device. Background Art

[0002] Simply put, elevator wireless intercom is a wireless call from the property duty room to the elevator room, car top, car and pit. In the process of using wireless intercom, it is necessary to equip it with an emergency power supply to provide power to the wireless intercom when the elevator power outage occurs, so that it can be used normally.

[0003] Whether the wireless intercom in the elevator is used normally is related to the safety of the passengers in the elevator. Therefore, in any case of the elevator, it is necessary to ensure that the emergency power supply can provide power to the wireless intercom.

[0004] When the existing emergency power supply is connected to the wireless intercom with a power cord, the power cord is often too long. At this time, the excessively long part of the power cord is easily suspended in the air, causing the power cord to shake easily during the operation of the elevator, causing friction with other objects, resulting in greater wear on the outer wall of the power cord.

[0005] Therefore, it is necessary to provide a new elevator wireless intercom emergency power supply device to solve the above-mentioned technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an elevator wireless intercom emergency power supply device.

[0007] The utility model provides an elevator wireless intercom emergency power supply device:

[0008] It includes a power supply shell, which is docked with a power cord, a rotatably connected screw rod is installed on one side of the power supply shell through a bracket, and a fixedly connected mounting rod is installed on one side of the power supply shell through the bracket, a threaded mounting seat is sleeved on the screw rod, and a limit rod is rotatably connected to the mounting seat, and the other end of the limit rod is slidably connected to the mounting rod.

[0009] Preferably, the power supply casing is provided with a back plate, and a rotatably connected shaft is mounted on the back plate through a frame, and screws with opposite threads are respectively provided at both ends of the shaft, and threaded fixing frames are sleeved on the screws, and the upper and lower ends of the fixing frames are fixedly connected to limit blocks.

[0010] Preferably, one side of the power supply housing is fixedly connected to a limiting seat, and the limiting seat is provided with a groove, and the power cord is located in the groove of the limiting seat.

[0013] Preferably, a rotatably connected knob A is installed on one side of the power supply housing through a frame, and the knob A is fixedly connected to the top end of the screw rod.

[0014] Preferably, a knob B for driving the shaft to rotate is mounted on the back plate through a frame, and the knob B is provided with a plurality of anti-slip grooves.

[0015] Compared with the related art, the elevator wireless intercom emergency power supply device provided by the utility model has the following beneficial effects:

[0016] 1. After the wireless intercom and the power supply are connected by the power cord, the screw rod is rotated to drive the limit rod to move downward. During the downward movement of the limit rod, the excess power cord can be pulled, and the excess part of the power cord is stuck in the groove of the limit seat to protect the power cord. This avoids the problem that the power cord of the traditional device is easily supported in the air due to being too long, and effectively improves the protection of the device for the power cord.

[0017] 2. When the power supply needs to be dismantled for maintenance, the utility model turns knob B to drive the shaft rod. During the rotation of the shaft rod, the screws at both ends of the shaft rod drive the fixing frame to move toward the two ends of the screw rod. As the fixing frame moves, the limit block is pulled out from the limit hole. Then the power supply casing can be removed and the power supply body inside can be inspected. When the inspection is completed, the power supply casing is attached to the back plate, and then knob B is turned in the opposite direction to install and fix the power supply casing, avoiding the problem that the traditional device needs to dismantle the entire power supply when repairing the power supply, and then reinstall it with screws, which makes the operation more troublesome.

[0035] The working principle of the elevator wireless intercom emergency power supply device provided by the utility model is as follows:

[0036] First, use screws to install the back plate 4 at the specified position, then fit the power supply housing 1 onto the back plate 4, and then turn the knob B45 to drive the shaft 41 and the screw 42 to rotate. At this time, since the screws 42 at both ends of the shaft 41 have opposite threads, when the shaft 41 rotates, the fixing frames 43 on the screws 42 at both ends will move closer to each other until the limit block 44 is stuck in the limit hole 11 of the power supply housing 1, completing the fixing work of the power supply housing 1;

[0037] Then, use the docking connector of the power cord 2 to plug the power cord 2 into the docking port 12, and then connect the other end of the power cord 2 to the elevator wireless intercom device;

[0038] After the power cord 2 is connected, ensure that the power cord 2 is located between the limiting seat 32 and the limiting rod 34, then turn the knob A35 to drive the screw rod 3 to rotate, and drive the limiting rod 34 to move downward. According to the excess length of the power cord 2, control the descending distance of the limiting rod 34, use the limiting rod 34 to squeeze the power cord 2, so that the excess part of the power cord 2 is stuck in the groove of the limiting seat 32, and use the limiting seat 32 and the limiting rod 34 to cooperate to limit and store the excess part of the power cord 2;

[0039] When the elevator loses power, the power cord 2 can be used to transmit the power of the power supply body in the power supply housing 1 to the wireless docking device, so that the wireless docking device can operate normally and protect the safety of people in the elevator;

[0040] When it is necessary to remove the power supply casing 1 and inspect the power supply body inside it, turn the knob B45 in the opposite direction to rotate the shaft 41 in the opposite direction. At this time, the screws 42 at both ends of the shaft 41 will drive the fixing frame 43 to separate from each other.
