Description

Technical Field

[0001] This utility model relates to the field of relay frames, and in particular to a relay frame that is easy to adjust. Background Technology

[0002] A relay is an electrical control device that causes a predetermined step change in the controlled variable in the electrical output circuit when the change in the input quantity (excitation quantity) reaches a specified requirement. It has an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). It is commonly used in automated control circuits, and is essentially an "automatic switch" that uses a small current to control a large current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] In existing technology, the relay frame, as a crucial internal component of the relay, has a fixed design. The frame's primary function is to support and secure the coil windings, ensuring the coil's stability and reliability. Therefore, the frame's size, shape, and material are determined during the design phase to suit specific relay types and operating environments. This design fixedness means that once manufactured, the frame cannot be adjusted or modified. Consequently, the relay frame cannot secure iron cores of varying heights or wind coils of different heights during use. Furthermore, the lack of securing measures after inserting the iron core into the frame's cylinder leads to core wobbling during operation, reducing the frame's applicability and practicality, and affecting the relay's normal operation. Utility Model Content

[0004] The main objective of this invention is to provide a relay frame that is easy to adjust, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An easily adjustable relay frame includes an upper frame plate and a lower frame plate. An adjustment mechanism is provided between the upper and lower frame plates, and the adjustment mechanism includes a first screw, a support cylinder, and an adjustment knob. An inner cylinder and an outer cylinder are fixedly connected to the opposite walls of the upper and lower frame plates, respectively, and the inner cylinder is movably connected to the outer cylinder. The support cylinder is fixedly connected to the top surface of the lower fixing plate at the rear end of the lower frame plate, and the adjustment knob is movably connected to the top of the support cylinder through a T-shaped slider on the bottom surface. The first screw is fixedly connected to the bottom surface of the upper fixing plate at the rear end of the upper frame plate and is movably connected to the adjustment knob. Fixing mechanisms are provided on the opposite walls of the upper and lower frame plates, and the fixing mechanisms include a second screw, a movable rod, and an arc-shaped clamping plate. The second screw is movably connected to the side walls of the symmetrical fixing blocks on the opposite walls of the upper and lower frame plates through a rotating rod, and the movable rod is movably connected to the second screw through a connecting block at one end. The arc-shaped clamping plate is fixedly connected to the inner end of the movable rod.

[0007] Preferably, a communicating outer cylinder is fixedly installed on the top surface of the lower bone plate, and a lower fixing plate is fixedly installed on the rear wall of the lower bone plate. A support cylinder is fixedly installed on the top surface of the lower fixing plate, and a T-shaped annular groove is formed on the top surface of the support cylinder. A limiting ring is also fixedly installed inside the top of the support cylinder, and a set of symmetrical guide blocks are fixedly installed on the inner wall of the limiting ring. A set of symmetrical T-shaped sliders is fixedly installed on the bottom surface of the adjusting knob, and the T-shaped sliders are movably installed in the T-shaped annular groove. A first screw hole is also formed on the top surface of the adjusting knob.

[0008] Preferably, the bottom surface of the upper bone plate is fixedly installed with a communicating inner cylinder, and the inner cylinder is inserted into the outer cylinder. An upper fixing plate is fixedly installed on the rear wall of the upper bone plate, and a first screw is fixedly installed on the bottom surface of the upper fixing plate. The first screw is threadedly connected to a first screw hole and passes through a limiting ring. A guide groove corresponding to the guide block is opened on the outer wall of the first screw.

[0009] Preferably, a set of symmetrical movable grooves are formed on the opposite walls of the upper and lower bone plates, and a through hole is formed on the inner end wall of the movable groove.

[0010] Preferably, a set of symmetrical fixing blocks are fixedly installed on the opposite walls of the upper and lower bone plates, and a rotating hole is opened on the side wall of the fixing block. A rotating rod is fixedly installed on the outer end of the second screw, and the rotating rod is movably installed in the rotating hole. A hand-tightening knob is also fixedly installed on the outer end of the rotating rod.

[0011] Preferably, the movable rod is inserted into the through hole, and a connecting block is fixedly installed on the outer end of the movable rod and movably installed in the movable groove. A second screw hole is opened on the side wall of the connecting block to be threadedly connected to the second screw. An arc-shaped clamping plate is fixedly installed on the inner end of the movable rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the adjustment mechanism involves rotating the adjustment knob, which drives the first screw through the first screw hole. The first screw moves upward along the guide block inside the limiting ring via guide grooves on both sides, adjusting the distance between the upper and lower skeleton plates. This allows the inner cylinder to move from inside the outer cylinder, achieving the purpose of adjusting the frame height according to the core height and winding requirements. This enables the frame to accommodate cores and coils of different heights during use. After inserting the core into the cylinder, rotating the hand-tight knobs on both sides of the upper and lower skeleton plates drives the second screw through the movable rod. This causes the connecting block to move inward through the second screw hole along the movable groove of the second screw, pushing the arc-shaped clamping plate through the through hole until both ends of the core are clamped and fixed between the arc-shaped clamping plates. This effectively fixes cores of different thicknesses, preventing core wobbling during use. This not only improves the applicability and practicality of the frame but also ensures the normal operation of the relay and facilitates adjustment of the relay frame. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 - Figure 4 As shown, a conveniently adjustable relay frame includes an upper bone plate 1 and a lower bone plate 2. An adjustment mechanism 5 is provided between the upper bone plate 1 and the lower bone plate 2. The adjustment mechanism 5 includes a first screw 9, a support cylinder 11, and an adjustment knob 15. An inner cylinder 3 and an outer cylinder 4 are fixedly connected to the opposite walls of the upper bone plate 1 and the bone plate 2, respectively. The inner cylinder 3 is movably connected inside the outer cylinder 4. The support cylinder 11 is fixedly connected to the top surface of the lower fixing plate 8 at the rear end of the lower bone plate 2. The adjustment knob 15 is movably connected to the top of the support cylinder 11 via a T-shaped slider 16 on the bottom surface. Rod 9 is fixedly connected to the bottom surface of the upper fixing plate 7 at the rear end of the upper bone plate 1 and is movably connected to the adjusting knob 15. Fixing mechanisms 6 are respectively provided on the opposite walls of the upper bone plate 1 and the lower bone plate 2. The fixing mechanism 6 includes a second screw 22, a movable rod 25 and an arc-shaped clamping plate 28. The second screw 22 is movably connected to the side wall of the symmetrical fixing block 20 on the opposite walls of the upper bone plate 1 and the lower bone plate 2 through the rotating rod 23. The movable rod 25 is movably connected to the second screw 22 through the connecting block 26 at one end. The arc-shaped clamping plate 28 is fixedly connected to the inner end of the movable rod 25.

[0021] like Figure 2 - Figure 3 As shown, a communicating outer cylinder 4 is fixedly installed on the top surface of the lower bone plate 2, and a lower fixing plate 8 is fixedly installed on the rear wall of the lower bone plate 2. A support cylinder 11 is fixedly installed on the top surface of the lower fixing plate 8, and a T-shaped annular groove 12 is formed on the top surface of the support cylinder 11. A limiting ring 13 is also fixedly installed inside the top of the support cylinder 11, and a set of symmetrical guide blocks 14 are fixedly installed on the inner wall of the limiting ring 13. A set of symmetrical T-shaped sliders 16 are fixedly installed on the bottom surface of the adjusting knob 15. The slider 16 is movably installed in the T-shaped annular groove 12. The top surface of the adjustment knob 15 is also provided with a first screw hole 17. After rotating the adjustment knob 15, the T-shaped slider 16 will slide in a ring within the T-shaped annular groove 12, and restrict the adjustment knob 15 from disengaging from the top of the support cylinder 11. This allows the adjustment knob 15 to drive the first screw 9 to move through the first screw hole 17, and the first screw 9 to move along the guide block 14 in the limiting ring 13 to adjust the distance between the upper bone plate 1 and the lower bone plate 2.

[0022] like Figure 2 - Figure 3As shown, an inner cylinder 3 is fixedly installed on the bottom surface of the upper bone plate 1, and the inner cylinder 3 is inserted into the outer cylinder 4. An upper fixing plate 7 is fixedly installed on the rear wall of the upper bone plate 1, and a first screw 9 is fixedly installed on the bottom surface of the upper fixing plate 7. The first screw 9 is threadedly connected to the first screw hole 17 and passes through the limiting ring 13. A guide groove 10 corresponding to the guide block 14 is opened on the outer wall of the first screw 9. The first screw 9 will move upward from the inside of the support cylinder 11 through the guide grooves 10 on both sides under the rotation of the adjustment knob 15, and lift the upper bone plate 1 upward, so that the inner cylinder 3 is moved out from the inside of the outer cylinder 4. This achieves the purpose of adjusting the height of the skeleton according to the iron core height and winding requirements, so that iron cores of different heights can be inserted into the cylinder and wound into coils of different heights.

[0023] like Figure 4 As shown, a set of symmetrical movable grooves 18 are respectively provided on the opposite walls of the upper bone plate 1 and the lower bone plate 2, and a through hole 19 is also provided on the inner end wall of the movable groove 18. The movable groove 18 and the through hole 19 are used to cooperate with the movable rod 25 to realize the movable operation.

[0024] like Figure 4 As shown, a set of symmetrical fixing blocks 20 are fixedly installed on the opposite walls of the upper bone plate 1 and the lower bone plate 2, and a rotating hole 21 is opened on the side wall of the fixing block 20. A rotating rod 23 is fixedly installed on the outer end of the second screw 22, and the rotating rod 23 is movably installed in the rotating hole 21. A hand-tightening knob 24 is also fixedly installed on the outer end of the rotating rod 23. Twisting the hand-tightening knob 24 causes the rotating rod 23 to rotate in the rotating hole 21 opened on the side wall of the fixing block 20, which can cause the rotating rod 23 to drive the second screw 22 to rotate.

[0025] like Figure 4 As shown, the movable rod 25 is inserted into the through hole 19, and a connecting block 26 is fixedly installed on the outer end of the movable rod 25 and movably installed in the movable groove 18. A second screw hole 27 is provided on the side wall of the connecting block 26, which is threaded to the second screw 22. An arc-shaped clamping plate 28 is fixedly installed on the inner end of the movable rod 25. Driven by the rotation of the second screw 22, the connecting block 26 will move along the second screw 22 through the second screw hole 27, so that the movable rod 25 moves in the movable groove 18 and passes through the through hole 19 to push the arc-shaped clamping plate 28. This can clamp and fix the two ends of the iron core between the arc-shaped clamping plate 28 to prevent the iron core from shaking when the relay is in use.

[0026] The specific operating principle of the relay frame in conjunction with the adjusting mechanism 5 and the fixing mechanism 6 is as follows:

[0027] Adjust the distance between the upper bone plate 1 and the lower bone plate 2 according to the height of the iron core. During adjustment, rotate the adjustment knob 15 at the top of the support cylinder 11 mounted on the top surface of the lower fixed plate 8. The T-shaped slider 16 on the bottom surface of the adjustment knob 15 will slide in a circular trajectory within the T-shaped annular groove 12 opened at the top of the support cylinder 11, so that the adjustment knob 15 can rotate at the top of the support cylinder 11. During the rotation of the adjustment knob 15, the first screw 9 will pass through the first screw hole 17 opened at the top surface and move from the inside of the support cylinder 11 outward along the first screw hole 17. The first screw 9 moves upward through the guide groove 10 on the outer wall and along the guide block 14 installed on the inner wall of the inner limiting ring 13 at the top of the support cylinder 11. The first screw 9 also pushes the upper bone plate 1 upward through the upper fixing plate 7, causing the upper bone plate 1 to move upward and drive the inner cylinder 3 on the bottom surface to move upward from the inner cylinder 3 installed on the top surface of the lower bone plate 2. Once the distance between the upper bone plate 1 and the lower bone plate 2 is adjusted to a suitable level, the coil can be wound around the outer walls of the inner cylinder 3 and the outer cylinder 4 to achieve the desired coil winding height. The purpose of adjustment is to change the height of the entire frame according to the height of the iron core. Then, the iron core is inserted into the cylinder. Then, the hand-cranked knobs 24 located on both sides of the upper bone plate 1 and the lower bone plate 2 are turned in sequence. The hand-cranked knobs 24 will drive the rotating rod 23 to rotate in the rotating hole 21 opened on the side wall of the fixed block 20. The rotating rod 23 will drive the second screw 22 to rotate, so that the connecting block 26 moves inward in the movable groove 18 along the second screw 22 through the second screw hole 27 opened on the side wall. The connecting block 26 will push the movable rod 25. By passing through the through hole 19 and moving the arc-shaped clamp 28 inwards within the cylinder until both ends of the iron core inside the cylinder are clamped and fixed between the symmetrical arc-shaped clamps 28, and the hand-twisted knob 24 can no longer be turned, the problem of the iron core shaking and becoming unstable during the use of the relay can be avoided. This allows the frame to have the functions of adjusting the iron core and winding height and fixing the iron core, thereby not only improving the applicability and practicality of the frame, but also ensuring the normal use of the relay and facilitating the adjustment of the relay frame.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
