[0002] The switch mechanism on existing electromagnetic locks is complex and uncompact. The rotating lever is a single piece, requiring assembly from the outside of the lock cover, from top to bottom. This is inconvenient and inefficient. After assembly, the wrench protrudes from the outside of the panel, making it prone to collisions and damage to the electromagnetic lock. Furthermore, the electromagnetic lock is prone to jamming during opening, posing a potential maintenance hazard. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art, the purpose of the utility model is to provide a rotary switch for an indoor electromagnetic lock, which has a simple structure, and after assembly, the wrench is tightly attached to the panel without collision, and has high assembly efficiency.

[0004] The technical solution adopted in this utility model is:

[0005] A rotary switch for an indoor electromagnetic lock is characterized by comprising a connector and a wrench, wherein the connector is rotatably mounted on a lock cover plate and its lower end passes through the lock cover plate and is connected to a lever; the upper end of the connector is connected to the wrench, and a spring is provided between the connector and the wrench to limit the relative position of the connector and the wrench.

[0006] Furthermore, a lever mounting groove and a fixing hole are provided at the lower end of the connector, wherein the lever for cooperating with the lock bolt is located in the mounting groove and fixed by the fixing hole and a screw. The lever is moved by turning a wrench, thereby moving the lock bolt.

[0007] Furthermore, the connector has an arc-shaped platform at its upper end, spring mounting holes on either side of the platform, and a through-hole within the platform. The front portion of the wrench has an arc-shaped slot that mates with the platform and a connecting hole that mates with the through-hole. The connector is connected via locating pins located in the through-hole and connecting hole. The wrench can rotate up and down with the connector through the engagement of the arc-shaped platform and the arc-shaped slot.

[0008] In order to make the spring fit tightly with the arc-shaped platform and facilitate the sliding of the spring, sliding grooves adapted to the spring are provided on both sides of the arc-shaped platform.

[0009] Furthermore, the spring can be placed below or above the arc-shaped platform, and both assembly methods can achieve the function of the rotary switch.

[0010] The first method involves a protrusion on the inside of the wrench, below the arc-shaped groove. One end of the spring is placed in the spring mounting hole below the arc-shaped platform, and the other end is inserted into the protrusion. A magnet is installed on the inside of the wrench to attach to the lock cover. In this method, the wrench is initially attached to the lock cover by magnetic force. When it is needed, a slight force is applied to lift the wrench to overcome the magnetic force. The spring allows the wrench to remain in the raised position after release, allowing the wrench to be turned to turn the switch. After use, a slight force is applied to press the wrench down. The magnet forces the wrench back to the lock cover, maintaining its initial position. The advantages of this method are: ease of operation; lifting the wrench and keeping it in the raised position serves as a pre-operation warning; and after the operation is completed, it reminds the operator to press the wrench down to maintain its initial position.

[0011] The second method places one end of the spring in the spring mounting hole above the curved platform, while the other end rests against the wrench, trapping the spring between the wrench and the lock cover. In this method, the wrench is initially attached to the lock cover by the spring. To use it, apply a little force to overcome the spring and lift the wrench, turning it to activate the switch. Once the wrench is used, the spring automatically attaches it to the lock cover, maintaining its initial position.

[0012] Furthermore, a circular limiting platform is provided in the middle of the connector, and a step adapted to the limiting platform is provided on the lock body cover. The connector is placed in the circular hole on the lock body cover and is limited by the limiting platform and the step, and the connector can rotate on the lock body cover.

[0013] The utility model has the following beneficial effects:

[0014] The utility model has a simple structure, and after assembly, the wrench is tightly attached to the panel without collision, and the assembly efficiency is high; at the same time, the two assembly methods meet different needs, the operation is flexible and convenient, and lifting the wrench and keeping it in the lifted state can play a pre-operation warning role.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 5 The figure shows a rotary switch for an indoor electromagnetic lock, comprising a connector 1, a lever 2, and a spring. The connector 1 is rotatably mounted on a lock cover 3, with its lower end extending through the cover and connected to a lever. The upper end of the connector is connected to the lever. The spring, located between the connector and the lever, restricts their relative position.

[0022] The specific structure is as follows: a lever mounting groove 11 and a fixing hole 12 are provided at the lower end of the connecting body, a lever for cooperating with the lock bolt is located in the mounting groove and fixed by the fixing hole and screws. The lever is driven to move by rotating the wrench 2, thereby moving the lock bolt.

[0023] The connector has an arc-shaped platform 13 at its top end, spring mounting holes 14 on either side, and a through-hole 15 within the platform. The front of the wrench has an arc-shaped slot 23 that mates with the platform and a connecting hole 25 that mates with the through-hole. The connector is connected via locating pins set in the through-hole and connecting hole. The wrench can rotate up and down with the connector through the engagement of the arc-shaped platform and the arc-shaped slot.

[0024] In order to make the spring fit tightly with the arc-shaped platform and facilitate the sliding of the spring, sliding grooves 16 adapted to the spring are provided on both sides of the arc-shaped platform.

[0025] The spring can be placed below or above the curved table, and both assembly methods can achieve the function of the rotary switch.

[0026] The first method involves a boss 24 located on the inside of the wrench, below the arc-shaped slot. One end of the spring is placed in the spring mounting hole 14 below the arc-shaped platform, and the other end is fitted over the boss 24. A magnet 21 is located on the inside of the wrench, designed to attach to the lock cover 3. The lock cover 3 is fitted with a screw 31 that engages with the magnet 21. In this method, the wrench is initially magnetically attached to the lock cover. To use the wrench, a slight force is applied to overcome the magnetic force and lift it. The spring allows the wrench to remain lifted after release, allowing the wrench to be turned to activate the switch. After use, a slight force is applied to the wrench, and the magnet forces the wrench back to the lock cover, maintaining its initial position. This method offers the advantages of ease of operation. Lifting the wrench and keeping it lifted serves as a pre-operation warning. Furthermore, after the operation is complete, the operator is reminded to press the wrench down, maintaining its initial position.

[0027] The second method places one end of the spring in the spring mounting hole 14 above the curved platform, while the other end rests against the wrench, trapping the spring between the wrench and the lock cover. In this method, the wrench is initially attached to the lock cover by the spring. To use it, a slight force is applied to overcome the spring's action, lifting the wrench, which can then be turned to activate the switch. Once the wrench is used, the spring automatically attaches it to the lock cover, maintaining its initial position.

[0028] To facilitate the installation of the connector, a circular limit platform 17 is provided in the middle of the connector, and a step 32 adapted to the limit platform is provided on the lock body cover 3. The connector is placed in the circular hole on the lock body cover and is limited by the limit platform and the step, and the connector can rotate on the lock body cover.

[0029] The utility model has a simple structure, and after assembly, the wrench is tightly attached to the panel without collision, and the assembly efficiency is high; at the same time, the two assembly methods meet different needs, the operation is flexible and convenient, and lifting the wrench and keeping it in the lifted state can play a pre-operation warning role.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as the scope of protection of the present invention.
