Description

Technical Field

[0001] The utility model relates to the field of motor equipment, in particular to an explosion-proof motor controller. Background Art

[0002] Explosion-proof motors are a commonly used device at present. Due to the particularity of the operating environment of explosion-proof motors, the motor controller is usually not integrated and installed on the motor body. The motor body and the motor controller are usually set separately. Patent announcement document CN219086467U discloses an explosion-proof control box for explosion-proof motors. The structure of the control box with this structure can be roughly regarded as an openable and closable box with electronic components installed on it. However, there is no corresponding mounting structure on the outer wall of the control box, so the explosion-proof control box with this structure cannot be installed on the wall or the outer wall of other equipment. Utility Model Content

[0003] In response to the above-mentioned problems, the utility model proposes an explosion-proof motor controller. This controller is easy to use and the disassembly and assembly process will not affect the strength of the box body by arranging a connecting plate with mounting holes on the box body. The connecting plate with mounting holes is used to connect with other equipment or walls.

[0004] The technical solutions adopted by this utility model are as follows:

[0005] A explosion-proof motor controller includes a box body, a control circuit board is provided in the box body, a control interface is provided on the control circuit board, the control interface is located outside the box body, a control keypad is provided on the outer wall of the box body, the control keypad is electrically connected to the control circuit board, a clamping plate is provided on the box body, the clamping plate is provided with a clamping hole, the control interface is arranged in the clamping hole, and also includes a plurality of connecting plates, the connecting plates are provided with four edges of the box body, and the connecting plates are located on the outer wall, the connecting plates are provided with mounting through holes, and all the connecting plates are in the same plane, and soft rubber gaskets are provided on the connecting plates.

[0006] In this explosion-proof motor controller, a connecting plate is provided on the outer wall of the box body, and a mounting through-hole is opened on the connecting plate, so that screws (or bolts) can be used to fix the box body to the wall or other equipment with the help of the connecting plate. At the same time, since a soft rubber gasket (which can be a soft rubber gasket made of rubber material) is provided on the connecting plate, the soft rubber gasket can play a buffering and shock-absorbing role between the connecting plate and the wall (or other equipment), thereby preventing the vibration of the wall (or the vibration generated during the operation of other equipment) from being transmitted to the box body, ensuring that the control circuit board in the box body will not be affected by external vibrations and can always operate smoothly.

[0007] In the same explosion-proof motor controller of this species, since the box body is installed by means of a connecting plate, the strength of the box body will not be affected during the process of unscrewing the screws during disassembly and assembly.

[0008] Specifically, in this explosion-proof motor controller of this species, the connecting plate can be a connecting plate made of plastic material or a connecting plate made of metal material.

[0009] Specifically, in this explosion-proof motor controller of this species, the box body is a box body made of metal material or hard plastic material, the clamping plate is a clamping plate made of soft PVC plastic material, the clamping plate has a certain flexibility, and the control interface is arranged on the clamping hole of the clamping plate. In this way, when the cable is inserted into or pulled out of the control interface and causes the control interface to shake, the mating strength of the box body will not be affected.

[0010] In summary, in this controller of this species, by setting a connecting plate with installation through holes on the box body and using the connecting plate with installation through holes to cooperate and connect with other equipment or walls, it is convenient to use, and the strength of the box body will not be affected during the disassembly and assembly process.

[0011] Optionally, a docking sleeve is arranged on the connecting plate, and installation through holes are distributed at both ends of the docking sleeve. The soft gasket and the docking sleeve are respectively located on both sides of the connecting plate. The docking sleeve is a hard docking sleeve, and a soft rubber sleeve is arranged inside the docking sleeve.

[0012] In this controller of this species, a docking sleeve is further arranged on the connecting plate. By setting the docking sleeve, the entire box body can be sleeved on equipment (and walls) with poles or hooks. At the same time, in order to ensure the stability of the docking sleeve after being sleeved on the pole, a soft rubber sleeve is further arranged inside the docking sleeve. The existence of the soft rubber sleeve can ensure that the pole and the docking sleeve are in a clamped state. Specifically, the soft rubber sleeve can be arranged inside the docking sleeve by bonding or hot melting.

[0013] Optionally, it further includes a sealing soft plug, and the sealing soft plug is inserted into the control interface.

[0014] The function of the sealing soft plug is to block the control interface when the control interface is not connected to the cable, avoiding the control interface being damaged by external objects due to being exposed.

[0015] Optionally, it further includes a display screen, and the display screen is arranged on the outer wall of the box body, and the display screen is electrically connected to the control circuit board.

[0016] Optionally, it further includes an RFID reader, and the RFID reader is arranged on the outer wall of the box body, and the RFID reader is electrically connected to the control circuit board.

[0017] The RFID reader is for enabling the controller to be opened and closed by swiping a card.

[0018] The beneficial effects of the present utility model are as follows: By providing a connecting plate with mounting through holes on the box body, and using the connecting plate with mounting through holes to cooperate and connect with other devices or walls, it is convenient to use, and the strength of the box body will not be affected during the disassembly and assembly process.
