[0001] The utility model relates to the technical field of relay production, in particular to a magnetic steel fixing structure for relays. Background Art

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

[0003] Existing magnetic steel fixing structures mostly use glue to adhere auxiliary accessories to limit and fix the magnetic steel. Since the glue solidifies quickly and cannot be controlled during flow, it is necessary to avoid the accessories from sticking crookedly and occupying the reserved space of other components. This requires high craftsmanship, greatly reduces the fixing speed, is inconvenient for users, and reduces the practicality of the fixing structure. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a magnetic steel fixing structure for relays, which has the advantages of fast and convenient fixing, and solves the problem that the existing magnetic steel fixing structure mostly uses glue to adhere auxiliary accessories to limit the position of the magnetic steel. Since the glue coagulates quickly and cannot be controlled during flow, it is necessary to avoid the accessories from sticking crookedly and occupying the reserved space of other components, which has high requirements on the process techniques and greatly reduces the fixing speed.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetic steel fixing structure for a relay, comprising a relay mounting plate, mounting seats are provided on both sides of the top of the relay mounting plate, and fixing plates are fixedly connected to both sides of the mounting seat, threaded holes corresponding to the fixing plates are provided on the surface of the top of the relay mounting plate, fixing grooves are provided on the surface of the outer side of the mounting seat, spring grooves are provided on both sides of the inner wall of the fixing groove, side walls of the spring grooves are fixedly connected to a first spring, the inner side of the first spring is fixedly connected to a spring block, and the sides of the spring block are provided with arc edges, sliding grooves are provided on both sides of the surface of the mounting seat, sliding rods are provided inside the sliding grooves, the top ends of the sliding rods penetrate to the top of the mounting seat and are fixedly connected to the top plate, the bottom of the top plate is fixedly connected to a pressing plate, and the pressing plate is slidably connected to the fixing groove.

[0006] As a preferred embodiment of the present invention, the bottom end of the slide rod is fixedly connected with a slider, the slider is slidably connected with the slide groove, and the surface of the slide rod is sleeved with a second spring.

[0007] As a preferred embodiment of the present invention, both sides of the top plate are fixedly connected with pull ears.

[0008] As a preferred embodiment of the present invention, the length of the spring slot is greater than the sum of the compression length of the first spring and the length of the spring block.

[0009] As a preferred embodiment of the present invention, the number of the first springs is multiple.

[0010] As a preferred embodiment of the present invention, the top diameter of the slide groove is smaller than the bottom diameter thereof.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model provides the first spring and the spring block. When the magnetic steel needs to be fixed, the fixing plate and the threaded holes on the surface of the relay mounting plate are first fixed and fastened by screws, and then the top plate is pulled upward, so that the bottom of the magnetic steel can be fitted with the surface of the relay mounting plate and align with the fixing groove to slide in. When the magnetic steel contacts the arc-shaped edge, it can slide in along the curvature of the arc-shaped edge. At the same time, the spring block is squeezed and then compresses the first spring, so that the spring block slides into the spring groove. When the magnetic steel completely slides into the fixing groove, the first spring stretches to push the spring block out and reset it, so that the magnetic steel can be limited and fixed. The fixing is convenient and fast, and there is no high requirement on the operator's craftsmanship. It is convenient for users to use and improves the practicality of the fixing structure.

[0013] 2. The utility model sets a second spring. When the height of the magnetic steel is relatively high, the second spring contracts and causes the slider to be lifted downward. The slider drives the slide bar and the top plate to be lifted downward, and the pressure plate is lifted downward to limit and fix the magnetic steel. The magnetic steel of higher size can be fixed, thereby further improving the applicability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 4 As shown, a magnetic steel fixing structure for a relay comprises a relay mounting plate 1, mounting seats 2 are provided on both sides of the top of the relay mounting plate 1, fixing plates 3 are fixedly connected on both sides of the mounting seat 2, threaded holes corresponding to the fixing plates 3 are provided on the surface of the top of the relay mounting plate 1, fixing grooves 4 are provided on the surface of the outer side of the mounting seat 2, spring grooves 5 are provided on both sides of the inner wall of the fixing groove 4, first springs 6 are fixedly connected to the side walls of the spring grooves 5, spring blocks 7 are fixedly connected to the inner sides of the first springs 6, arc-shaped edges 8 are provided on the sides of the spring blocks 7, sliding grooves 9 are provided on both sides of the surface of the mounting seat 2, sliding rods 10 are provided inside the sliding grooves 9, the top ends of the sliding rods 10 penetrate to the top of the mounting seat 2 and are fixedly connected to the top plate 11, the bottom of the top plate 11 is fixedly connected to the pressing plate 12, and the pressing plate 12 is slidably connected to the fixing groove 4.

[0021] refer to Figure 3 The bottom end of the slide bar 10 is fixedly connected with a slide block 13, the slide block 13 is slidably connected with the slide groove 9, and the surface of the slide bar 10 is sleeved with a second spring 14.

[0022] As a technical optimization solution of the utility model, through the setting of the second spring 14, when the height of the magnetic steel is relatively high, the second spring 14 contracts and causes the slider 13 to be subjected to a downward lifting force. The slider 13 drives the slide rod 10 and the top plate 11 to be lifted downward, and the pressure plate 12 is lifted downward to limit and fix the magnetic steel. It can fix magnetic steel of higher size, further improving the applicability of the structure.

[0023] refer to Figure 1 and Figure 2 Pull ears 15 are fixedly connected to both sides of the top plate 11.

[0024] As a technical optimization solution of the utility model, the contact area between the top plate 11 and the hand is increased by setting the pull ear 15, making it more convenient and quick to pull the top plate 11, thereby improving the fixing speed of the magnetic steel.

[0025] refer to Figures 2 to 4 , the length of the spring slot 5 is greater than the sum of the compressed length of the first spring 6 and the length of the spring block 7.

[0026] As a technical optimization solution of the utility model, by setting the length of the spring slot 5 to be greater than the sum of the compression length of the first spring 6 and the length of the spring block 7, the problem that the spring slot 5 is not long enough, resulting in the spring block 7 being unable to slide completely into the spring slot 5, thereby making the magnetic steel unable to slide into the fixing slot 4 for fixation is avoided.

[0027] refer to Figure 2 and Figure 3 , the number of the first springs 6 is several.

[0028] As a technical optimization solution of the present invention, by setting the number of first springs 6 to be multiple, the problem of uneven force on the spring block 7, which causes the two ends of the spring block to be skewed and the magnet to be easily dislodged, is avoided, thereby improving the stability of the structure.

[0029] refer to Figure 2 , the top diameter of the chute 9 is smaller than the bottom diameter thereof.

[0030] As a technical optimization solution of the utility model, by setting the top diameter of the slide slot 9 to be smaller than the bottom diameter thereof, the second spring 14 will not fall out of the slide slot 9 and cause the limit of the top of the magnetic steel to fail.

[0031] The working principle and use process of the utility model are as follows: when using, when the user needs to fix the magnetic steel, first fix and tighten the fixing plate 3 and the threaded holes on the surface of the relay mounting plate 1 by screws, and then pull the top plate 11 upward, the top plate 11 drives the slide bar 10 to rise and compress the second spring 14, and then the bottom of the magnetic steel is fitted with the surface of the relay mounting plate 1, and aligns with the fixing groove 4 and slides in. When the magnetic steel contacts the arc edge 8, it can slide in along the curvature of the arc edge 8, and at the same time, the spring block 7 is squeezed and then compresses the first spring 6, so that the spring block 7 slides into the spring groove 5. When the magnetic steel completely slides into the fixing groove 4, the first spring 6 stretches to push the spring block 7 out and reset it, so that the two sides of the magnetic steel can be limited and fixed, and at the same time, the top plate 11 is lowered, and the second spring 14 stretches to make the slider 13 subject to a downward jacking force, and the slider 13 drives the slide bar 10 and the top plate 11 to be lifted downward, and the pressure plate 12 is lifted downward to limit and fix the top of the magnetic steel, so as to complete the fixation of the magnetic steel.
