Description

Technical Field

[0001] This utility model relates to the field of door and window processing technology, specifically to a motor calibration device for intelligent doors and windows. Background Technology

[0002] In intelligent door and window systems, the motor, as the core driving component, directly affects the normal operation and effectiveness of the intelligent doors and windows. To ensure that the intelligent door and window motor operates accurately according to preset parameters under various operating conditions, it needs to be calibrated regularly. A multimeter, a commonly used electronic measuring instrument, plays a crucial role in the calibration process of intelligent door and window motors. It can accurately measure parameters such as motor voltage, current, and resistance, providing accurate data support for motor calibration and ensuring that the motor's performance indicators meet design requirements.

[0003] When using a multimeter to calibrate the motors of smart doors and windows, the multimeter is connected to the instrument body through two wire plugs connecting the probes to transmit measurement signals. However, in actual operation, due to the complex and diverse working environment, there are external forces such as vibration and collisions that can cause the multimeter plugs to loosen, resulting in the interruption of the measurement work and affecting the accuracy of the measurement data and the reliability of the calibration work. Utility Model Content

[0004] The purpose of this invention is to provide a motor calibration device for intelligent doors and windows, which solves the problem of loose plugs by limiting the plug with a stop and a torsion spring.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a motor calibration device for intelligent doors and windows, including a multimeter body and a limiting part. A rectangular block is installed on the top of the multimeter body. The limiting part has a stop block and a rotating shaft. A through hole is opened on the stop block, and the rotating shaft is sleeved in the through hole. A through hole matching the rotating shaft is opened on the top of the rectangular block. A torsion spring is sleeved on the end of the rotating shaft. A circular groove is opened on the rectangular block, and the circular groove is connected to the through hole. The two ends of the torsion spring are respectively connected to the inner wall of the circular groove and the outer surface of the stop block.

[0007] Furthermore, two vertical blocks are installed at the bottom of the stop block.

[0008] Furthermore, a clearance groove is provided at the top of the rectangular block, which is connected to the through hole, and the end of the stop block is located in the clearance groove.

[0009] Furthermore, an L-shaped rod is connected to the end of the shaft.

[0010] Furthermore, a reserved groove is provided at the top of the rectangular block, a magnet is installed in the reserved groove, and a metal block is installed at the end of the block, with the metal block magnetically connected to the magnet.

[0011] Furthermore, the multimeter body has a socket, into which a plug is inserted, and the plug contacts the bottom of the stop block.

[0012] This utility model has the following beneficial effects:

[0013] This utility model limits the plug by setting a stop and a torsion spring. The design of the spring driving the stop provides a reliable limiting effect for the plug, which can resist external interference such as vibration, collision and human touch that may occur during the operation, ensuring that the plug is always firmly plugged into the multimeter, avoiding the problem of measurement signal interruption caused by loose plug, and ensuring the continuity and stability of measurement work.

[0014] This invention uses a magnet and a metal block to fix the stop. When the plug needs to be removed from the socket, the L-shaped rod is rotated to drive the shaft to rotate the stop to a vertical position. At this time, the metal block is engaged with one side of the reserved slot and is attracted by the torsion spring. The stop does not hinder the plug insertion and removal operation, thereby improving the convenience of operation, simplifying the operation process, reducing the operation time interval, and improving the overall work efficiency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a motor calibration device for intelligent doors and windows, including a multimeter body 1 and a limiting part. The multimeter body 1 has a socket 101, and a plug 102 is inserted into the socket 101. The plug 102 contacts the bottom of a stop block 3 and is connected to the wires of the test leads. A rectangular block 2 is mounted on the top of the multimeter body 1. A relief groove 201 is formed on the top of the rectangular block 2, which communicates with a through hole 202. The end of the stop block 3 is located in the relief groove 201. When the rectangular block 2 rotates along the rotating shaft 4, the end of the rectangular block 2 engages in the relief groove 201, preventing... The limiting part has a stop block 3 and a rotating shaft 4, which affect the rotation. The end of the rotating shaft 4 is connected to an L-shaped rod 401. The L-shaped rod 401 facilitates the rotation of the rotating shaft 4. There are two vertical blocks 302 installed at the bottom of the stop block 3. The stop block 3 has a through hole 301. The rotating shaft 4 is sleeved in the through hole 301. The top of the rectangular block 2 has a through hole 202 that matches the rotating shaft 4. The end of the rotating shaft 4 is sleeved with a torsion spring 5. The rectangular block 2 has a circular groove 203 that communicates with the through hole 202. The two ends of the torsion spring 5 are respectively connected to the inner wall of the circular groove 203 and the outer surface of the stop block 3.

[0023] When removing plug 102, rotate L-shaped rod 401 to drive shaft 4 to a vertical position. At this time, torsion spring 5 is compressed. Then remove plug 102 from socket 101. When calibrating and testing the motor of smart doors and windows, use multimeter body 1. Insert plug 102 with test lead wires into socket 101. Then rotate L-shaped rod 401 to drive shaft 4 to rotate in through hole 202. After the metal block 7 leaves magnet 6, release L-shaped rod 401. At this time, torsion spring 5 rebounds and pushes shaft 4 to drive stop block 3 to rotate along shaft 4 until stop block 3 contacts the top of plug 102. At this time, two vertical blocks 302 are located on both sides of plug 102, which work with stop block 3 to limit plug 102.

[0024] The top of the rectangular block 2 has a reserved slot 204, and a magnet 6 is installed in the reserved slot 204. A metal block 7 is installed at the end of the stop block 3. The metal block 7 is magnetically connected to the magnet 6. When it is necessary to remove the plug 102 from the socket 101, the L-shaped rod 401 is rotated to drive the rotating shaft 4 so that the stop block 3 rotates to a vertical position. At this time, the metal block 7 is engaged with one side of the reserved slot 204 and is attracted by the torsion spring 5. At this time, the stop block 3 does not hinder the plug 102 from being inserted or removed.
