Description

Technical Field

[0001] This utility model relates to the technical field of motor overheat protection devices, specifically a motor overheat protection device. Background Technology

[0002] An overheat protection device for an electric motor is a device that protects an electric motor from overload. Damage to an electric motor is mainly caused by overheating of the windings or a decrease in insulation performance. Overheating of the windings is often caused by excessive current flowing through the windings. Electric motor protection devices mainly protect electric motors through two types of detection: current and temperature.

[0003] Existing motor overheat protection devices have a junction box located at the bottom of the device, which makes subsequent wiring or disconnection inconvenient after the device is fixedly installed. It is also inconvenient to rotate and adjust the installed motor overheat protection device to position the junction box at a better viewing and installation angle. Therefore, we propose a motor overheat protection device. Utility Model Content

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an electric motor overheat protection device. Example 1

[0028] Combination Figure 1-6As shown, this utility model provides an electric motor overheat protection device, comprising: an electric motor protector 100 and an adjustment assembly 200; the electric motor protector 100 includes a control panel 101 and a connector 102 fixedly installed at its front end and bottom respectively, and wiring screws 103 and wiring holes 104 arranged and installed inside the connector 102; the adjustment assembly 200 includes a fixed plate 201 fixedly installed at the center of the rear end of the electric motor protector 100, and a left mounting plate 202 and a right mounting plate 203 movably installed on both sides of the fixed plate 201 respectively. The binding groove 204 is opened at the inner end of both the 02 and the right mounting plate 203; the first locking hole 205 and the second locking hole 206 are opened on both sides of the fixing plate 201 respectively; the mounting cavity 207 is opened in the right mounting plate 203; the first fixing plate 208 is fixedly installed on one side of the mounting cavity 207; the first mounting hole 209 is opened through one side of the first fixing plate 208; the locking post 210 is movably installed in the first mounting hole 209; the second mounting hole 211 is opened on one side of the right mounting plate 203; the adjusting post 212 is movably installed in the second mounting hole 211; the locking post 210 and The wire harness 213 is fixedly connected between the adjusting columns 212. A fixed pulley 214 is also fixedly installed on one side of the mounting cavity 207, and the wire harness 213 is located within the fixed pulley 214. A second fixing plate 215 is also fixedly installed on one side of the mounting cavity 207. A first spring 216 is fixedly installed between the second fixing plate 215 and the locking column 210. A cable routing hole 217 is also opened through the second fixing plate 215, and the wire harness 213 is located inside the cable routing hole 217. A second spring 218 is also fixedly installed between the first fixing plate 208 and the adjusting column 212. The left mounting plate 20... Positioning holes 219 are provided on both sides. Positioning rods 220 are fixedly installed on both sides of the right mounting plate 203, and the positioning rods 220 and positioning holes 219 are matched. Grooves 221 are provided through both sides of the left mounting plate 202 and both sides of the right mounting plate 203. Locking screws 222 are movably installed in the grooves 221. The fixing plate 201 is movably installed in the binding grooves 204 on both sides, and the fixing plate 201 has a T-shaped structure. The first locking hole 205 and the second locking hole 206 have the same structure. The locking post 210 and the adjusting post 212 are both T-shaped post structures.

[0029] Specifically, the motor overheat protection device is a device that protects the motor from overload. After the motor protector 100 is fixedly installed by the locking screws 222 on both sides of the left mounting plate 202 and the right mounting plate 203, during subsequent wiring, the adjusting post 212 on the outside of the right mounting plate 203 can be pressed to remove the locking post 210 that is engaged in the first locking hole 205 in the rear fixing plate 201 of the motor protector 100, thereby protecting the motor without disassembling the motor protector 100. The motor protector 100 rotates independently, causing the connector 102 at the bottom of the motor protector 100 to rotate to the side. This allows for more precise and clear wiring and disconnection of the upper connection wires of the connector 102, improving the convenience and accuracy of wiring installation and disconnection. Furthermore, after the motor protector 100 is rotated and adjusted, the locking pin 210 can be re-engaged into the second locking hole 206 on the other side of the fixing plate 201 by loosening the adjusting pin 212, thus ensuring proper connection between the connector 102 and the motor. The protector 100 is stable. Furthermore, during the overall disassembly and maintenance of the motor protector 100, only the right mounting plate 203 on the rear side needs to be removed to remove the motor protector 100, thus improving the convenience of disassembly and assembly during maintenance. The first spring 216, fixedly installed between the locking post 210 and the second fixing plate 215, is mainly used for the automatic return of the locking post 210 when it is not pulled by the wire harness 213. The second spring 218, fixedly installed between the first fixing plate 208 and the adjusting post 212, is mainly used for the adjusting post 212 when it is not pressed... The automatic return to its original position after being pressed down, and then the automatically released wire harness 213, the positioning holes 219 on both sides of the left mounting plate 202 and the positioning rods 220 on both sides of the right mounting plate 203 are mainly used for positioning connection after the left mounting plate 202 and the right mounting plate 203 are installed, and the locking screws 222 installed in the slots 221 on both sides of the left mounting plate 202 and the right mounting plate 203 are mainly used to fix the left mounting plate 202 and the right mounting plate 203 to the wall or equipment, and then fix the motor protector 100 at its front end.

[0030] Working principle and usage process of this utility model:

[0031] When wiring or disconnecting the motor protector 100 after it has been fixedly installed, first press the adjusting column 212 on one side of the right mounting plate 203 while supporting the motor protector 100. As the adjusting column 212 is pressed inward, it will compress the second spring 218 at its inner end and pull the wire harness 213 on one side. After the wire harness 213 is pulled, it will pull the locking column 210 at its other end, compress the first spring 216 at its rear end, and move inward to move out of the first locking hole 205 in the fixing plate 201. After the adjusting column 212 is pressed to the innermost end, the locking column 210 is completely moved out of the first locking hole 205. At this time, the motor protector 100 can be rotated 90 degrees to adjust the connector 102 at its bottom. Turn to the side, to the wiring area which is in a bright, clear and spacious location. After rotating the motor protector 100, release the pressing adjustment column 212 so that it is no longer pulled on the wire harness 213. This allows the locking column 210 to move outward under the elastic force of the first spring 216 and into the second locking hole 206 on the other side of the rear fixing plate 201 of the motor protector 100. This temporarily fixes the motor protector 100 and ensures stability during wiring and disconnection on the side connector 102. After wiring or disconnection on the connector 102 is completed, press the adjustment column 212 and rotate the motor protector 100 to easily return it to its original position.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
