Description

Technical Field

[0001] The utility model relates to the field of controller protection, in particular to a protection device for an automation controller. Background Art

[0002] A motor controller is a device or system used to control the operation of a motor. It usually consists of hardware and software. The main function of a motor controller is to receive signals from external inputs and convert them into corresponding actions or operating instructions for the motor.

[0003] Most of the existing motor controllers are protected by a protective cover or a hollow shell to prevent the motor controller from being directly impacted by external forces and being damaged and deformed. However, the sizes of the existing protective covers or hollow shells are fixed and cannot be adjusted according to motor controllers of different sizes. It is easy to cause the motor controller to be too large and the protective cover or hollow shell to be too small, making the protective cover or hollow shell unable to protect the motor controller.

[0004] Therefore, it is necessary to invent a protection device for an automation controller. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protection device for an automation controller, comprising a protection mechanism, the protection mechanism comprising an L-shaped connecting plate and a positioning plate and a protective side plate symmetrically installed on both sides of the L-shaped connecting plate, the positioning plate being movably plugged into the inner side of the protective side plate, and fixing components being symmetrically installed on both sides of the outer end of the protective side plate, and a controller being installed inside the protection mechanism.

[0007] Based on the above characteristics: four L-shaped connecting plates and four protective side plates are provided. When the L-shaped connecting plate, the positioning plate and the protective side plates are combined, a protective shell with a rectangular structure will be formed. When used in combination, the positioning plates on both sides of the L-shaped connecting plate are first plugged into the two sides of the protective side plates, and then the connection between the positioning plate and the protective side plates is fixed by the fixing assembly. Finally, the controller can be plugged into the protective shell for protection.

[0008] Preferably, the positioning plate is provided with slots spaced apart in the middle, and the spacing between adjacent slots is the same.

[0009] Based on the above features: when the positioning plate is connected to the protective side plate, the fixing component can be inserted into the card slot to fix the positioning plate and the protective side plate to prevent the positioning plate and the protective side plate from separating by themselves after being connected.

[0010] Preferably, slots are symmetrically provided on both sides of the protective side plates, and through holes are symmetrically provided on the outer walls on both sides of the protective side plates.

[0011] Based on the above features: the positioning plate is inserted into both sides of the protective side plate through the slot, and when the through hole on the surface of the protective side plate is aligned with the card slot, the fixing component can be used to insert and fix it.

[0012] Preferably, the interior of the protective side plate is a hollow structure, and the positioning plate is movably connected to the protective side plate.

[0013] Based on the above features: the positioning plate can be conveniently inserted into the interior of the protective side plate, and the positioning plate can be pulled out or inserted into the interior of the protective side plate as needed.

[0014] Preferably, the fixing assembly comprises a fixing plate and a guide rod movably connected in the middle of the fixing plate, a clamping block is installed at one end of the guide rod, and a buffer spring is sleeved on the outside of the guide rod.

[0015] Based on the above characteristics: pull the guide rod to move, so that the block at one end of the guide rod is separated from the slot and the through hole, and the buffer spring will be squeezed and deformed. When the guide rod is released, the buffer spring will rebound the guide rod and the block.

[0016] Preferably, a through hole is provided in the middle of one side of the fixing plate away from the protective side plate, and the guide rod movably passes through the through hole.

[0017] Based on the above features: it is convenient for the guide rod to pull the clamping block to move through the through hole, and since the diameter of the buffer spring is larger than the through hole, the buffer spring cannot pass through the through hole.

[0018] Preferably, the slot has the same diameter as the through hole.

[0019] Based on the above features: it is convenient for the card block to pass through the through hole and be inserted into the card slot for fixation.

[0020] The beneficial effects of the utility model are:

[0021] 1. The overall diameter of the protective shell can be increased or decreased to meet the installation needs of controllers of different sizes. When it is necessary to adjust according to the size of the controller, the guide rod can be pulled to move first to make the block at one end of the guide rod disengage from the slot and the through hole. At this time, the buffer spring will be squeezed and deformed, and then the positioning plate can be pulled or pushed. When the positioning plate is adjusted to the required position, the slot and the through hole can be aligned. Finally, the guide rod is released, and the buffer spring will rebound the guide rod and the block, so that the block passes through the through hole and is fixed in the slot, thereby preventing the positioning plate from separating by itself after being connected to the protective side plate.

[0022] 2. It is convenient for the protective shell to be disassembled and assembled. There are four L-shaped connecting plates and protective side plates. When the L-shaped connecting plate, the positioning plate and the protective side plates are combined, a rectangular protective shell will be formed. It is in a detachable state. When used in combination, first insert the positioning plates on both sides of the L-shaped connecting plate into the two sides of the protective side plates, and then use the fixing components to fix the connection between the positioning plates and the protective side plates. When not in use, you can unlock the fixing components, and then pull out the positioning plates and separate them from the protective side plates. BRIEF DESCRIPTION OF THE DRAWINGS
