Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically to an electrical equipment relay control device. Background Technology

[0002] A relay control device is an electrical control device that, when given a specified input quantity and held for a sufficient time, causes a predetermined step change in the controlled quantity in the electrical output circuit. Once the input quantity drops to a certain level and is held for a sufficiently long time, it returns to its initial state.

[0003] Existing relay control devices are assembled by fixing the cover plate to the housing with multiple fastening bolts. The various components on the relay are mounted on the mounting plate inside the housing. When the components on the relay are damaged and need to be repaired, multiple fastening bolts need to be removed with tools, and then the components inside the housing need to be taken out. This operation is cumbersome. In addition, the threaded holes are easily damaged during the installation and removal of the fastening bolts. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example:

[0029] like Figure 1-7 As shown, this embodiment of the invention provides an electrical equipment relay control device, including a housing 1. A mounting cavity 2 is provided inside the housing 1. A first spring 3 is fixedly connected to the rear wall of the mounting cavity 2. The first spring 3 is mainly used to eject a mounting plate 4 from inside the mounting cavity 2. The front end of the first spring 3 is fixedly connected to the mounting plate 4, and the mounting plate 4 is slidably connected to the housing 1. The mounting plate 4 is mainly used to fix relay elements (not shown in the figure). Connecting posts 5 are fixedly connected to the four corners of the front side wall of the mounting plate 4. The connecting posts 5 are mainly used to fix slide rails 6. The front end of the connecting column 5 is fixedly connected to a slide rail 6. The slide rail 6, slide groove 7 and slider 8 are designed to allow the fixing plate 9 and control panel 10 to slide down automatically under the action of gravity when opened, and expose the relay components on the mounting plate 4, which is convenient for the staff to repair and replace the relay components. The slide rail 6 is provided with a slide groove 7, and the slider 8 is slidably connected inside the slide groove 7. The front side of the slide rail 6 is slidably connected to a fixing plate 9, and the fixing plate 9 is fixedly connected to the slider 8. The slider 8 is located near the top of the fixing plate 9. The control panel 10 is fixedly connected to the front side wall of the fixing plate 9.

[0030] The left and right side walls of the housing 1 are provided with sliding holes 13. The sliding holes 13 facilitate the sliding of the positioning block 14. The positioning block 14 is slidably connected inside the sliding hole 13, and the positioning block 14 is fixedly connected to the mounting plate 4. The positioning block 14 and the positioning post 15 facilitate the base plate 18 to fix the mounting plate 4. The top of the positioning block 14 is fixedly connected to the positioning post 15. The left and right side walls of the housing 1 are fixedly connected with positioning plates 16, and the positioning plates 16 are located above the sliding holes 13 for positioning. A pull rod 17 is slidably connected inside the plate 16. A top plate 19 is fixedly connected to the top of the pull rod 17, and the top plate 19 is located above the housing 1. A handle 20 is fixedly connected to the top of the top plate 19. The handle 20 is mainly used to control the top plate 19 to move the pull rod 17 upward, thereby controlling the bottom plate 18 to move upward, so that the bottom plate 18 releases the positioning block 14, making it convenient for the mounting plate 4 to slide. The bottom end of the pull rod 17 is fixedly connected to the bottom plate 18, and a first positioning hole is provided inside the bottom plate 18. The first positioning hole 21 is located in front of the second positioning hole 22. A second spring 23 is sleeved on the circumferential surface of the pull rod 17 and is located between the positioning plate 16 and the base plate 18. The second spring 23 is mainly used to control the base plate 18 to move downward so that the positioning pin 15 can be inserted into the first positioning hole 21 or the second positioning hole 22, and to prevent the positioning pin 15 from falling out of the first positioning hole 21 or the second positioning hole 22. Two support plates 24 are fixedly connected to the left and right side walls of the housing 1. The support plates 24 are mainly used to support the base plate 18. The two support plates 24 are symmetrically arranged on the front and rear sides of the sliding hole 13. By setting the first positioning hole 21 and the second positioning hole 22, it is convenient to fix the mounting plate 4 with the positioning pin 15. When the positioning pin 15 is inserted into the first positioning hole 21, the control panel 10 is in the open state. When the positioning pin 15 is inserted into the second positioning hole 22, the control panel 10 is in the closed state.

[0031] The control panel 10 has a display screen 11 and control buttons 12 on its front side wall, with the display screen 11 located above the control buttons 12. Mounting blocks 25 are fixedly connected to the top and bottom of the housing 1 and are located at the four corners of the housing 1. The mounting blocks 25 are mainly used to fix the housing 1 to the wall or mechanical equipment.

[0032] There are two slide rails 6, symmetrically distributed on the left and right sides of the fixed plate 9. The number of slide grooves 7 and sliders 8 is the same as the number of slide rails 6. The top surface of slide grooves 7 and sliders 8 is convex to prevent sliders 8 from falling out of the slide groove 7. There are four pull rods 17 and four second springs 23, symmetrically arranged in pairs on the left and right sides of the housing 1. The four pull rods 17 and four second springs 23 are mainly to ensure the stability of the bottom plate 18 moving up and down. The first positioning hole 21 and the second positioning hole 22 are corresponding to the positioning post 15, and the first positioning hole 21 and the second positioning hole 22 are used in conjunction with the positioning post 15.

[0033] Working principle: When the relay element on the mounting plate 4 is damaged, the top plate 19, pull rod 17, and bottom plate 18 are first moved upward by the handle 20, causing the positioning pin 15 to move out of the second positioning hole 22. At this time, the mounting plate 4 and control panel 10 pop out of the mounting cavity 2 under the action of the first spring 3. When the control panel 10 pops out of the mounting cavity 2, the control panel 10 and slider 8 slide downward under the action of gravity, exposing the relay element on the mounting plate 4. When the positioning block 14 moves to the front end of the sliding hole 13, the handle 20 is released. At this time, the bottom plate 18 moves downward under the action of the second spring 23 and gravity, causing the positioning pin 15 to insert into the first positioning hole 21. Inside, the mounting plate 4 is then fixed. After that, the maintenance personnel repair and replace the relay components. After the repair is completed, the maintenance personnel first lift the base plate 18 with the handle 20, so that the positioning pin 15 is pulled out from the inside of the first positioning hole 21. Then, the maintenance personnel use the other hand to lift the control panel 10, so that the slider 8 slides to the top of the slide groove 7. Then, the fixing plate 9 and the mounting plate 4 are pushed into the inside of the mounting cavity 2. When the fixing plate 9 enters the inside of the mounting cavity 2, the control panel 10 is attached to the front side wall of the housing 1. Finally, the handle 20 is released, and the base plate 18 moves downward under the action of the second spring 23 and gravity, so that the positioning pin 15 is inserted into the inside of the second positioning hole 22, and the mounting plate 4 is fixed.
