Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet installation technology, and in particular to an installation structure for reducing the vibration of PLC controllers. Background Technology

[0002] PLC controllers are typically fixed in electrical control cabinets with screws. Since PLC controllers are generally made of plastic insulating material, the screws should not be squeezed when tightening, otherwise they may break over time.

[0003] The application, with application number 201820963325.3 and titled "PLC Controller Anti-interference Installation Structure," includes a base, a PLC mounting base, and a baffle. The base 1 has an installation groove, and the PLC mounting base is placed in the mounting groove and locked in place by a floating locking component, allowing the PLC mounting base to float up and down. The PLC mounting base has a PLC controller mounting slot, and the baffle can close the slot after rotation, completing the installation process of the PLC controller and preventing dust from entering the PLC controller. The floating locking component allows the PLC mounting base to float up and down, and locks the baffle onto the PLC mounting base, facilitating the fixation and protection of the PLC controller.

[0004] However, it also has its shortcomings: 1) The floating locking component allows the PLC placement base to float up and down, but its floating range is large. Since there is no protective measure at the top, it will cause small movements to cause the PLC placement base to float, which will cause the PLC controller to vibrate; 2) Since the PLC controller and the PLC placement slot cannot be perfectly matched and there will be a gap in the middle, the floating will also cause the controller to vibrate. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides an installation structure that reduces the vibration of the PLC controller, thus solving the problem that the controller is prone to vibration in the current anti-interference installation structure, which affects the final performance.

[0006] This utility model solves the technical problem through the following technical means: a mounting structure that reduces the vibration of the PLC controller, including a base, a PLC mounting base, a baffle, and a floating locking component;

[0007] The base is equipped with a vertically sliding clamping plate. The lower end of the clamping plate is located above the PLC placement seat. The clamping plate slides down and presses the PLC placement seat to fix the PLC placement seat.

[0008] The PLC mounting base is equipped with a horizontally sliding clamping plate, which contacts the PLC controller to form a structure that fixes the PLC controller.

[0009] Preferably, a guide rod is fixed to the upper end of the card plate, and the upper end of the guide rod slidably passes through the base and is fixed with an operating plate. A first spring is fitted around the outer circumference of the guide rod. The upper end of the first spring is fixedly connected to the base, and the lower end of the first spring is fixedly connected to the card plate. The first spring is a structure that drives the card plate to move downward.

[0010] Preferably, the base has two rotatable support plates at its upper end, and the support plates rotate to lift the operation plate after it slides upward.

[0011] Preferably, the upper end of the base is rotatably provided with a pressure plate, the pressure plate being a structure that allows the lower end of the operating plate to be tightly attached to the upper end of the base.

[0012] Preferably, the clamping plate is provided with one or two sets, and the outer end of the clamping plate is rotatably connected with a first threaded rod. The first threaded rod is threadedly connected to the PLC placement seat and the outer end is placed outside the PLC placement seat.

[0013] A guide rod is fixed to the outer end of the clamping plate, and the guide rod slides through the PLC placement base.

[0014] Preferably, the base is provided with an adjustable vertical sliding sleeve, and a sliding rod is slidably provided inside the sliding sleeve. The upper end of the sliding rod passes through the sliding sleeve and is fixedly connected to a top plate. The upper end of the top plate contacts the PLC placement seat to form a structure that locks the PLC placement seat.

[0028] The following is in conjunction with the appendix Figure 1 —5 provides a further detailed description of the specific embodiments of this utility model.

[0029] like Figure 1-5 As shown, the mounting structure for reducing PLC controller vibration includes a base 1, a PLC mounting base 2, a baffle 3, and a floating locking component.

[0030] The base 1 is provided with a vertically sliding clamping plate 4. The lower end of the clamping plate 4 is located above the PLC placement seat 2. The clamping plate 4 slides down and presses the PLC placement seat 2 to fix the PLC placement seat 2.

[0031] The PLC mounting base 2 is provided with a horizontally sliding clamping plate 5, which contacts the PLC controller to form a structure for fixing the PLC controller.

[0032] This device is an improvement on the application No. 201820963325.3 entitled "PLC Controller Anti-interference Installation Structure". It still retains the base 1, PLC placement seat 2, baffle 3 and floating locking component. The base 1 and PLC placement seat 2 also retain clearance grooves to facilitate the lead-out of wires inside the PLC controller. The PLC controller is locked into the PLC placement seat 2 by the baffle 3 and the floating locking component.

[0033] This device adds a vertically sliding clamping plate 4. After the PLC placement seat 2 is placed into the base 1, the lower end of the clamping plate 4 makes pressing contact with the upper end of the PLC placement seat 2, thereby providing a clamping force to the PLC placement seat 2. This can effectively prevent the PLC placement seat 2 from vibrating over a large range.

[0034] In addition, after the PLC controller is placed in the PLC mounting base 2, the PLC controller is clamped by the clamping plate 5, which can better ensure the stability of the PLC controller in the PLC mounting base 2.

[0035] This device reduces the vibration of the PLC controller in two ways. First, it clamps the PLC mounting base 2 with the clamping plate 4, which reduces the vibration of the PLC mounting base 2. Second, it clamps the PLC controller with the clamping plate 5, which reduces the vibration fluctuation.

[0036] The upper end of the card plate 4 is fixed with a guide rod 6. The upper end of the guide rod 6 slidably passes through the base 1 and is fixed with an operating plate 10. A first spring 7 is fitted around the outer circumference of the guide rod 6. The upper end of the first spring 7 is fixedly connected to the base 1, and the lower end of the first spring 7 is fixedly connected to the card plate 4. The first spring 7 is a structure that drives the card plate 4 to move downward.

[0037] The first spring 7 provides a downward force, which causes the clamping plate 4 to press against the PLC mounting base 2. This retains the anti-interference function while reducing the vibration amplitude of the PLC mounting base 2, thereby reducing damage to the PLC controller and extending its service life.

[0038] By lifting the operating plate 10 upwards, the card plate 4 is raised, preventing it from contacting the PLC mounting base 2. This makes subsequent maintenance and replacement more convenient.

[0039] The clamping plate 5 is provided with one or two sets, and the outer end of the clamping plate 5 is rotatably connected with a first threaded rod 12. The first threaded rod 12 is threadedly connected to the PLC placement seat 2 and its outer end is placed outside the PLC placement seat 2.

[0040] The outer end of the clamping plate 5 is fixed with a guide rod 13, which slides through the PLC placement seat 2.

[0041] In this device, the clamping plates 5 can be set in one or two sets. When there is one set, one end of the PLC controller is in close contact with the PLC placement seat 2, and then the clamping plate 5 clamps the PLC controller. When there are two sets, the two sets of clamping plates 5 are located on both sides of the PLC placement seat 2, and the two sets of clamping plates 5 are respectively located on both sides of the PLC controller, so as to contact the PLC controller and complete the clamping of the PLC controller.

[0042] The base 1 is provided with an adjustable vertical sliding sleeve 14. A sliding rod 15 is slidably provided inside the sliding sleeve 14. The upper end of the sliding rod 15 passes through the sliding sleeve 14 and is fixedly connected to a top plate 16. The upper end of the top plate 16 contacts the PLC placement seat 2 to form a structure that locks the PLC placement seat 2.

[0043] In this device, a sliding sleeve 14 is added to adjust the vertical position, which can adjust the initial clamping effect and better control the vibration amplitude. In addition, the contact area between the top plate 16 and the PLC mounting base 2 is increased, which increases the force-bearing surface and makes the PLC mounting base 2 more stable.

[0044] The base 1 is rotatably provided with a second threaded rod 17, the upper end of which is threadedly connected to the sliding sleeve 14 and placed inside the sliding sleeve 14;

[0045] The base 1 has a guide shaft 18 fixed inside, and a sliding sleeve 14 that can slide through the upper end of the guide shaft 18.

[0046] The rotation of the second threaded rod 17 causes the sliding sleeve 14 to slide vertically. The upper end of the second threaded rod 17 is always inside the sliding sleeve 14. In addition, a horizontal plate is fixed on one side of the sliding sleeve 14, and the upper end of the guide shaft 18 passes through the horizontal plate, which plays a guiding role.

[0047] When the tray 9 contacts the PLC mounting base 2, the second threaded rod 17 is screwed on again, causing the sliding sleeve 14 to rise. This increases the clamping force on the PLC mounting base 2 and reduces the vibration and floating of the PLC controller.

[0048] The sliding sleeve 14 is provided with a vertically sliding plug 19, and the plug 19 is fixedly connected to the lower end of the sliding rod 15;

[0049] The sliding sleeve 14 is provided with a vertical guide groove, and a guide block is slidably provided in the guide groove. The guide block passes through the guide groove and is fixedly connected to the plug 19.

[0050] The plug 19 effectively prevents the slide rod 15 from separating from the sliding sleeve 14. The cooperation between the guide groove and the guide block effectively ensures the vertical sliding effect of the slide rod 15, that is, the verticality of the top plate 16.

[0051] A second spring 20 is fixed inside the sliding sleeve 14. The lower end of the second spring 20 is fixedly connected to the sliding sleeve 14, and the upper end of the second spring 20 is fixedly connected to the plug 19. The second spring 20 is a structure that drives the plug 19 to move upward.

[0052] With the second spring 20 in place, an initial preload is provided, ensuring floatability while reducing vibration.

[0053] The base 1 has two rotatable support plates 9 on its upper end. After the operating plate 10 slides upward, the support plates 9 rotate to lift the operating plate 10.

[0054] The tray 9 can rotate. After the operating plate 10 is pulled upward, the tray 9 swings, so that the tray 9 supports the operating plate 10, thus locking the position of the card plate 4, making it convenient for the PLC placement seat 2 to be installed into the base 1.

[0055] The upper end of the base 1 is rotatably provided with a pressure plate 11, which is designed to make the lower end of the operating plate 10 fit tightly against the upper end of the base 1.

[0056] To achieve better results, press down on the operating plate 10 so that it contacts the upper surface of the base 1. Then rotate the pressure plate 11, which will lock the operating plate 10 in place, preventing it from rising again.

[0057] In this device, the tray 9 and the clamp 4 can be rotated without limiting the operation plate 10.

[0058] During installation, this device still adopts the installation method described in application number 201820963325.3, entitled "PLC Controller Anti-interference Installation Structure". Then, rotate the support plate 9 to make the operation plate 10 move downward. Press down on the operation plate 10 to make it contact the base 1. Use the pressure plate 11 to lock the operation plate 10. Then drive the clamping plate 5 to fix the PLC controller. Finally, screw the second threaded rod 17 to make the second spring 20 contract and the preload force is greater, thereby reducing vibration and floating while ensuring that the PLC placement seat 2 floats.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
