Description

Technical Field

[0001] This utility model relates to the field of locking device technology, specifically a locking device for fitness equipment in an unmanned gym. Background Technology

[0002] With the rapid development of the fitness industry, the unmanned gym model has gradually become popular due to its low operating costs and 24-hour operation. In unmanned management scenarios, how to effectively control the usage status of fitness equipment has become a key issue. Currently, fitness equipment can be divided into two categories: one is intelligent equipment with its own electrical control system (such as electric treadmills, electromagnetic resistance exercise bikes, etc.), and the other is traditional equipment with a purely mechanical structure (such as dumbbell racks, cable racks, mechanical strength training machines, etc.). Intelligent fitness equipment, equipped with motors, electromagnets, or servo systems, can be started, stopped, and its functions locked by directly switching power on and off or sending commands through a central control system. For example, a treadmill can be stopped remotely by cutting off power, or fitness equipment with adjustable electromagnetic resistance can be controlled by signals. Unmanned management of this type of equipment is relatively easy to achieve. However, gyms contain a large number of mechanical machines that are not electrically powered, such as barbell racks, dumbbell racks, machine cabinets, and mechanical training machines. These machines do not have electrical control interfaces, and their moving parts (such as counterweights, levers, hooks, etc.) are usually fixed by mechanical pins or manual adjustment devices. In unattended scenarios, how to remotely lock and manage these purely mechanical machines has become a technical challenge. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a locking device that is simple to install, flexible to use, and has excellent locking effect.

[0004] The technical solution adopted by this utility model to achieve the above objectives is: a locking device for fitness equipment in an unmanned gym, including a device shell, a locking tongue, a pushing mechanism, a locking mechanism, and an unmanned control system. The pushing mechanism is provided inside the device shell. The pushing mechanism includes a pushing platform. The locking tongue is fixedly connected to the pushing platform. A through hole is provided on the device shell corresponding to the locking tongue. The locking mechanism is provided inside the device housing, and the locking tongue is provided with a locking hole, which is engaged with the locking mechanism. The unmanned control system is installed inside the device housing, and the unmanned control system cooperates with the pushing mechanism and the locking mechanism.

[0005] In the above technical solution, the specific structure of the driving mechanism is as follows: The pushing mechanism further includes a drive motor, a lead screw, and a sliding column. The sliding column is fixedly connected inside the device housing. The pushing platform is slidably connected to the sliding column. A lead screw sleeve is fixedly connected to the pushing platform. The lead screw sleeve cooperates with the lead screw. The drive motor is fixedly connected inside the device housing. The drive motor is poweredly connected to the lead screw. The drive motor is electrically connected to the unmanned control system.

[0006] In the above technical solution, the specific structure of the locking mechanism is as follows: The locking mechanism includes a frame, an electromagnet, a locking pin, and a spring. The frame is fixedly connected inside the housing. The locking pin is slidably connected to the frame. A moving pin is fixedly connected to the locking pin. An adsorption platform is fixedly connected to the top of the moving pin. The electromagnet is fixedly connected to the frame corresponding to the adsorption platform. The spring is fitted onto the moving pin. One end of the spring is fixedly connected to the locking pin, and the other end is fixedly connected to the frame. The locking pin engages with the locking hole. The electromagnet is electrically connected to the unmanned control system.

[0007] In the above technical solution, to improve the stability of the locking tongue, further: A guide strip is fixedly connected to the side of the perforation inside the housing of the device.

Furthermore, the locking mechanism is located on the top of the locking tongue, and the locking hole is located on the top of the locking tongue.

[0010] The beneficial effects of this utility model are: 1. The device can be fixedly installed in a suitable part of the fitness equipment as needed. The drive motor is controlled by the unmanned control system, which drives the lead screw to rotate. This causes the pusher to drive the locking tongue to pass through the hole. The locking tongue limits the movement of the fitness equipment, making the fitness equipment unusable. This meets the needs of unmanned gyms. It is simple to install and flexible to use. 2. After the locking tongue locks the fitness equipment, the electromagnet can be controlled by the unmanned control system to insert the locking pin into the locking hole, further locking the locking tongue, resulting in excellent locking effect, strong impact resistance, and resistance to easy damage by external forces. 3. The push platform is installed on a fixed sliding column, ensuring the linearity of its movement trajectory and bearing the main pushing and pulling forces. Two sets of guide strips are set on both sides of the through hole at the protruding end of the locking tongue, which cooperate with the guide groove on the tongue. Combined with the locking mechanism (locking column) arranged on the top of the locking tongue, the locking hole is also opened on the top. This layout can enhance the load-bearing capacity of the locking tongue and ensure the excellent locking effect of the device. Attached Figure Description

Detailed Implementation

[0013] 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.

[0014] Please see Figures 1-4A locking device for fitness equipment in an unmanned gym includes a device housing 100, a locking tongue 200, a pushing mechanism, a locking mechanism, and an unmanned control system. Firstly, the device housing 100 contains a pushing mechanism, specifically including a pushing platform 301, a drive motor 302, a lead screw 303, and a sliding column 304. That is, a sliding column 304 is fixedly connected inside the device housing 100, and the pushing platform 301 is slidably connected to the sliding column 304. A lead screw 303 sleeve is fixedly connected to the pushing platform 301, and the lead screw 303 sleeve cooperates with the lead screw 303. The drive motor 302 is fixedly connected inside the device housing 100, and the drive motor 302 is poweredly connected to the lead screw 303. The drive motor 302 can drive the lead screw 303 to rotate, and then, with the lead screw 303 and the lead screw 303 sleeve cooperating, the pushing platform 301 can slide linearly on the sliding column 304. In addition, a locking tongue 200 is fixedly connected to the aforementioned push platform 301, and a through hole is provided on the device housing 100 corresponding to the locking tongue 200, so that the push platform 301 can drive the locking tongue 200 to pass through or into the through hole. Secondly, the device housing 100 is equipped with a locking mechanism. The locking tongue 200 has a locking hole 201, and the locking mechanism engages with the locking hole 201. Specifically, the locking mechanism includes a mechanism frame 401, an electromagnet 402, a locking pin 403, and a spring 404. That is, the mechanism frame 401 is fixedly connected inside the device housing 100, a sliding strip 405 is fixedly connected to the mechanism frame 401, and a sliding groove 406 is provided on the locking pin 403 to cooperate with the sliding strip 405. The sliding strip 405 is slidably connected in the sliding groove 406. A moving pin 407 is fixedly connected to the locking pin 403, and the top of the moving pin 407 is fixedly... An adsorption platform 408 is fixedly connected to the mechanism frame 401, and an electromagnet 402 is fixedly connected to the adsorption platform 408. A spring 404 is sleeved on the moving column 407. One end of the spring 404 is fixedly connected to the aforementioned locking column 403, and the other end is fixedly connected to the mechanism frame 401. The locking column 403 cooperates with the locking hole 201. In this way, when the electromagnet 402 adsorbs the adsorption platform 408, the spring 404 can be compressed, and the locking column 403 can be disengaged from the locking hole 201. When the electromagnet 402 is demagnetized, the locking column 403 can be inserted into the locking hole 201 under the elastic force of the spring 404. Furthermore, a guide strip 501 is fixedly connected to the side of the perforation inside the housing 100. A guide groove 502 is provided on the locking tongue 200 to cooperate with the guide strip 501. The guide strip 501 is slidably connected in the guide groove 502. Specifically, two sets of guide strips 501 are used, and the two sets of guide strips 501 are located on both sides of the perforation. Furthermore, the locking mechanism is located at the top of the locking tongue 200, and the locking hole 201 is located at the top of the locking tongue 200. Through the above structure, the locking stability and impact resistance of the locking tongue 200 can be enhanced. Finally, the device housing 100 is equipped with an unmanned control system. The unmanned control system is electrically connected to the electromagnet 402 and the drive motor 302. Specifically, the unmanned control system receives remote commands (such as user APP reservation success signal, background management command, etc.), controls the drive motor 302 to rotate, which drives the lead screw 303 to rotate, pushes the platform 301 to move forward along the sliding column 304, and causes the locking tongue 200 to extend out of the through hole in the device housing 100 and insert into the gap or hole of the moving parts of the instrument to prevent its movement. When the locking tongue 200 passes through the hole, the electromagnet 402 does not attract the adsorption plate. At this time, the spring 404 is in a compressed state under the push of the locking tongue 200. When the locking tongue 200 moves so that the locking hole 201 corresponds to the locking pin 403, the locking pin 403 is inserted into the locking hole 201 under the elastic force of the spring 404. When it is necessary to unlock the fitness equipment, first power on the electromagnet 402, and the electromagnet 402 will attract the adsorption platform 408. At this time, the locking pin 403 will reset and exit the locking hole 201. Then control the drive motor 302 to reverse and retract the locking tongue 200. After the locking tongue 200 is retracted, the electromagnet 402 will be de-energized. Furthermore, the aforementioned unmanned control system is a fitness equipment locking / unlocking system controlled by remote commands (such as an APP or backend). Specifically, it includes a main controller (such as an STM32 / Arduino) responsible for logic processing, a power supply module that powers the controller, drive motor 302, and electromagnet 402, and a signal module (WiFi / Bluetooth / 4G module, such as ESP8266) for remote signal reception. The specific control process is as follows: I. Locking process: a. Received a remote locking command (e.g., successful reservation via APP).

[0015] b. The controller starts the drive motor 302 (forward rotation), which pushes the lead screw 303 to rotate, causing the locking tongue 200 to extend.

[0016] c. During the extension of the locking tongue 200, the spring 404 is compressed, and the locking pin 403 does not move.

[0017] d. When the locking tongue 200 is fully extended (which can be determined by the motor steps / time or limit switch), the locking hole 201 is aligned with the locking pin 403, and the spring 404 pushes the locking pin 403 into the locking hole 201 (mechanical locking is completed).

[0018] e. The motor stops (maintains its position; the motor does not require continuous power supply).

[0019] II. Unlocking process: a. Received a remote unlock command.

[0020] b. The controller first powers the electromagnet 402 (e.g., through a relay), and the electromagnet 402 attracts the adsorption plate, causing the locking pin 403 to disengage from the locking hole 201.

[0021] c. Delay for a short period of time (e.g., 100ms) to ensure that locking pin 403 is fully retracted.

[0022] d. Start the drive motor 302 (reverse) and retract the locking tongue 200.

[0023] e. After the locking tongue 200 is fully retracted (detected by motor steps / time or limit switch), stop the motor.

[0024] f. De-energize electromagnet 402 (release the adsorption plate).

[0025] Any system that can achieve the desired effect can be used as an unmanned control system.

[0026] Furthermore, the usage of this embodiment on certain instruments is as follows: 1. When the object to be locked is an adjustable bench press / sit-up board, a locking device can be installed inside the bench frame at the position corresponding to the adjustment hole. The locking tongue 200 extends out and inserts into the adjustment hole of the bench back, making the backrest angle unable to be adjusted or folded. The locking tongue 200 retracts, and the user can adjust and use it. 2. When the object being locked is a tension / rope device, a locking device is installed inside the frame of the counterweight stack. The locking tongue 200 extends out and inserts into the gap between the counterweights to "wedge" the entire counterweight stack, making it impossible to pull up. When the locking tongue 200 retracts, the pin can be pulled out from the counterweights, and the device can be used normally. 3. When the object being locked is a barbell / dumbbell plate, a locking device is installed behind each weight area of ​​the dumbbell rack or barbell plate rack. The locking tongue 200 is positioned directly opposite the hole in the center of the barbell plate. The locking tongue 200 extends and inserts into the hole of the outermost barbell plate, so that all the barbell plates are "stringed" on the locking tongue 200 and cannot be removed. The locking tongue 200 retracts, and the user can remove the required barbell plates from the rack. 4. When locking a gantry frame / power frame, drill a hole in the upright of the gantry frame or install an accessory with a hole. Install the locking device inside or on the back of the upright, so that the through hole is aligned with these holes. The locking tongue 200 extends out from the through hole of the device housing 100 and is directly inserted into the hole in the upright of the gantry frame, thereby blocking the lifting and lowering path of the barbell plates. When the locking tongue 200 retracts, the barbell plate hanger can move freely up and down.
