Technical Field

[0001] The utility model relates to the field of crane remote controllers, in particular to a crane remote controller with a key switch. Background Art

[0002] A crane remote control with a key switch is a specially designed crane operating control device. It is similar to a regular crane remote control, but with an added key switch function to provide additional safety and operational control. Usually in addition to the key switch function, a crane remote control with a key switch usually also has standard remote control operating functions. It may include multiple control buttons, switches or joysticks for controlling various crane actions such as lifting, lowering, moving, etc.

[0003] The control button body of the existing crane remote control with a key switch is generally directly exposed to the outside of the controller. Since cranes are mainly used in construction sites and other places, the control buttons are easily affected by pollutants such as dust, dirt, and moisture in the working environment. These pollutants may enter the buttons and cause poor contact, short circuits or other electrical failures. In addition, the control buttons are more susceptible to physical impact or scratches, which may cause the button surface to be worn, the markings to be unclear, or the buttons themselves to be damaged, affecting their use. At this time, it is necessary to provide a new type of crane remote control with a key switch that can effectively solve the above problems. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a crane remote controller with a key switch to solve the technical problem that the control buttons on the traditional crane remote controller with a key switch are defective.

[0005] To achieve the above object, the utility model provides the following technical solution: a crane remote controller with a key switch, comprising a remote controller, a key hole is arranged on one side of the remote controller, a control button is arranged below the outer surface of the remote controller, a protection mechanism is arranged on the outer surface of the control button, the protection mechanism comprises a shell, an adhesive sheet is arranged on the back of the shell, and the shell is adhered to the remote controller through the adhesive sheet;

[0006] A spring slot is arranged inside the shell, a spring is arranged inside the spring slot, a pressing block is arranged at the inner axis of the spring, the pressing block passes through the top and bottom of the shell, and a pressing button is arranged on the top of the pressing block.

[0007] By adopting the above technical solution, the keyhole is set to ensure that the remote control can only be operated by people holding the correct key, effectively preventing unauthorized use. In addition, using the key for switch operation is simple and intuitive, without the need for a complicated learning process, thereby improving work efficiency.

[0008] Furthermore, a lower pressing plate is fixedly connected to the lower pressing block, the lower pressing plate is in contact with the spring, and the lower pressing block is slidably connected to the spring groove.

[0009] By adopting the above technical solution, the protection mechanism covers the control button, effectively preventing the button from being accidentally touched, reducing the risk of operating errors, and the protection mechanism can reduce the wear and damage of the control button, thereby extending the overall service life of the remote control.

[0010] Furthermore, the spring is used to reset the pressing block, and the pressing block is used to touch the control button.

[0011] By adopting the above technical solution, the elastic force of the spring enables the push-down block to provide clear feedback when the control button is touched, so that the operator can clearly feel that the operation has been successfully performed. In addition, the combined design of the spring and the push-down block ensures the stability and consistency of the operation, thereby improving the reliability of the remote control.

[0012] Furthermore, an NFC scanning port is provided on the upper outer surface of the remote control, and the NFC scanning port is used to scan the NFC magnetic sheet to unlock the function of the remote control.

[0013] By adopting the above technical solution, in the event that the key is forgotten or lost, the NFC scanning port provides a convenient backup unlocking method, which increases the flexibility of operation. In addition, NFC technology has high security and protects the remote control from being used by unauthorized persons through encryption and identity authentication.

[0014] Furthermore, an emergency stop button is provided on one side of the NFC scanning port, and a prompt light is provided below the emergency stop button.

[0015] By adopting the above technical solution, the emergency stop button allows the operator to quickly cut off the power supply of the crane in an emergency to prevent accidents.

[0016] Furthermore, two prompt lights are provided, and the two prompt lights are used to display a power light and a signal light respectively.

[0017] By adopting the above technical solution, the indicator light can intuitively display the power and signal status of the remote control, making it convenient for the operator to understand the working status of the remote control at any time and make timely adjustments.

[0018] Furthermore, six control buttons are provided, and the six control buttons are respectively used to control the lifting and direction of the crane.

[0019] By adopting the above technical solution, the six control buttons can control multiple functions of the crane respectively, meet the needs of complex operations, and improve work efficiency. In addition, the button layout is reasonable and ergonomically designed, making the operation more comfortable and natural.

[0022] Furthermore, a signal line is provided on the top of the remote controller, and the signal line is used to send a signal to the crane.

[0023] By adopting the above technical solution, the signal line is used to send signals to the crane, which ensures stable communication between the remote control and the crane and reduces the possibility of signal interference or interruption. In addition, the interface design of the signal line makes connection and disconnection simple and quick, thereby improving work efficiency and convenience.

[0024] Furthermore, the protection mechanism is provided in multiple groups, and the number of the multiple groups of protection mechanisms is the same as the control buttons.

[0025] By adopting the above technical solution, multiple sets of protection mechanisms ensure that each control button is fully protected, thereby improving the safety of the entire remote control. Moreover, all buttons adopt the same protection mechanism design, which maintains consistency and ease of operation and reduces the risk of misoperation.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model provides a protection mechanism, wherein the housing can provide the first line of defense for the control button to prevent it from being damaged by external impact, scratches or moisture. This physical protection significantly extends the service life of the control button. In addition, due to the design of the push-down block and the push button, the operator needs to intentionally press the push button to touch the control button, which greatly reduces the risk of misoperation caused by accidental touch and improves the safety of operation. In addition, the presence of the spring not only provides a reset function for the push-down block, but also provides clear operation feedback for the operator. When the push button is pressed, the compression and release of the spring will give the operator a clear "click" feeling, ensuring that they know that the control button has been successfully touched. At the same time, when maintenance or replacement is required, it can be easily removed from the remote control through the adhesive sheet, which greatly facilitates maintenance and replacement work.

[0028] 2. The utility model provides an NFC scanning port, wherein the NFC scanning port is integrated above the outer surface of the remote control. When the operator does not have a key or wants to unlock the remote control function more quickly, the NFC scanning port can be used to bring an NFC magnetic sheet containing preset information close to the NFC scanning port. Once the scan is successful and the information of the NFC magnetic sheet is verified, the function of the remote control will be unlocked, allowing the operator to control the crane through the control button.
