In this state, the adhesive 5 fixes the bottom of the coil 4 with the base 101, and the cover plate 202 presses the top of the coil 4, that is, the coil 4 and the magnetic ring 3 are doubly fixed, so that the stability of connection between the magnetic ring 3 and the coil 4 and the framework 1 is greatly improved, and the situation that the magnetic ring 3 and the coil 4 are loosened is not easy to occur; in addition, as the cover plate 202 is added, the cover plate 202 can be sucked by an automatic sucking disc in the production process, so that the transformer is sucked and transferred, and the defects of low efficiency and easy error in the traditional manual feeding are overcome.

An elongated locking tongue 112 is provided in the accommodating groove 109, both ends of the locking tongue 112 are arc-shaped, a waist-shaped hole is provided in the locking tongue 112 along the length direction thereof, a support shaft 114 is provided in the waist-shaped hole 113 in a penetrating manner, and the support shaft 114 is fixed to the side wall of the accommodating groove 109. The structure is that the lock tongue 112 can rotate around the supporting shaft 114, and the relative position of the lock tongue 112 and the supporting shaft 114 can be adjusted.

The upper end of the push rod 110 is provided with a slope, and the slope is in contact with the end of the latch 112.

The upper end side wall of the inserted column 201 is symmetrically provided with a limit groove 205, the limit groove 205 is used for allowing the lock tongue 112 to enter, and the height of the limit groove 205 is larger than that of the lock tongue 112; an elastic washer 206 is fixed to the bottom edge of the cover plate 202 along the circumferential direction thereof, and is used for pressing the coil 4.

As shown in fig. 4, in an initial state, that is, when the latch 2 is separated from the bracket 103, the movable block 111 is located at an innermost position thereof, and at this time, the distance from the movable block 111 to the pushing member 106 is minimum; the ejector rod 110 is located at the lowest position, the lock tongue 112 is in a horizontal state, and the lock tongue 112 is located at the outermost position, i.e. the distance between the lock tongue 112 and the center of the lock hole 104 is the largest, and at this time, the lock tongue 112 is hidden in the accommodating groove 109.

Referring to fig. 7, in the process of assembling the transformer, after the magnetic ring 3 around which the coil 4 is wound is sleeved on the bracket 103, the lock catch 2 can be installed immediately; during the process of installing the lock catch 2, when the plunger 201 enters the lock hole 104 and the lower end of the plunger 201 starts to contact with the pushing member 106, the cover plate 202 is continuously pressed down, and at this time, the pushing member 106 starts to enter the bifurcation 203 of the plunger 201; because the pushing member 106 is tapered, during the subsequent lowering of the plunger 201, the pushing member 106 will push the petals at the lower end of the plunger 201, so that the petals of the two groups bend outwards and away from each other; the flange 204 contacts the movable block 111 and pushes the movable block 111 outwards in the process of bending the valve body outwards, and when the movable block 111 moves outwards, the ejector rod 110 is driven to rise, so that the upper end of the ejector rod 110 begins to push the lock tongue 112 to move inwards, and at the moment, the lock tongue 112 begins to approach the center of the lock hole 104.

Namely, in the process that the plunger 201 enters the lock hole 104, the limit groove 205 on the plunger 201 descends synchronously along with the plunger 201, when the lower end of the plunger 201 contacts with the pushing piece 106, the lock tongue 112 starts to approach the plunger 201, meanwhile, the elastic washer 206 contacts with the coil 4 and starts to press the coil 4 downwards, when the inner end of the lock tongue 112 enters the limit groove 205, the cover plate 202 is released, at this moment, the elastic force of the elastic washer 206 drives the cover plate 202 to communicate with the plunger 201 to retract upwards for a small distance, at this moment, the bottom surface of the limit groove 205 compresses the inner end of the lock tongue 112 upwards, and the outer end of the lock tongue 112 is compressed upwards by the bottom surface of the solute groove, and then the lock tongue 112 is stably kept in the current horizontal state by combining with the supporting force of the supporting shaft 114, at this moment, the plunger 201 is locked by the lock tongue 112 and cannot be pulled outwards, and thus the connection and fixation of the lock catch 2 and the framework 1 are completed.

Referring to fig. 8, when the latch 2 is to be removed, only the cover 202 needs to be pushed down with continued force, at which time the plunger 201 continues to descend and the pushing member 106 continues to push the petals outwards; the flange 204 drives the movable block 111 to continue to move outwards, at this time, the ejector rod 110 continues to ascend, and the ejector rod 110 drives the lock tongue 112 to further extend into the limit groove 205 until the outer end of the kidney-shaped hole on the lock tongue 112 contacts with the support shaft 114, so that the lock tongue 112 moves to the innermost position; at this time, the weight of the section of the lock tongue 112 located at the inner side of the support shaft 114 is greater than the weight of the section of the lock tongue 112 located at the outer side of the support shaft 114, and according to the lever principle, the inner end of the lock tongue 112 swings downwards, and the lock tongue 112 swings to descend along with the limit groove 205, so that the inner end of the lock tongue 112 can be separated from the limit groove 205; when the lock tongue 112 is separated from the limit groove 205, the gravity of the lock tongue 112 keeps the lock tongue 112 in an inclined state as shown in fig. 8, then the pressure on the cover plate 202 can be released and the cover plate 202 is held to lift the lock catch 2 upwards, and as the lock tongue 112 is kept in a lower swinging state so as to be hidden in the accommodating groove 109 again, the lock tongue 112 can not enter the limit groove 205 in the process of lifting the plug 201 upwards, the plug 201 can be ensured to be pulled out smoothly, and when the flange 204 at the lower end of the plug 201 is lifted to the position of the accommodating groove 109, the elasticity of the valve body enables the flange 204 to enter the accommodating groove 109, and the flange 204 contacts with the bottom of the inner end of the lock tongue 112 after entering the accommodating groove 109; with the continued lifting of the flap body, the flange 204 lifts the inner end of the lock tongue 112 upwards, the inner end of the lock tongue 112 swings upwards, the lock tongue 112 moves outwards, when the flange 204 starts to separate the lock tongue 112, the weight of the outer end of the lock tongue 112 is larger than that of the inner end of the lock tongue 112, the lock tongue 112 returns to the initial position, when the plunger 201 is completely separated from the lock hole 104, the lock catch 2 is unlocked, then the adhesive force of the adhesive 5 on the coil 4 can be relieved through hot melting or other means, and then the joint between the coil 4 and the pin 102 is fused, so that the magnetic ring 3 and the coil 4 can be detached integrally from the framework 1.

By adopting the structure and the operation, the coil 4 and the magnetic ring 3 can be effectively reinforced and fixed, and the situation that the coil 4 and the magnetic ring 3 are loosened after the transformer is used for a long time is prevented; and can realize the locking and unlocking of hasp 2 through simple second grade pressing action, greatly made things convenient for paster magnetic ring 3 transformer's whole equipment and dismantlement.

Considering that the lock catch 2 is separated from the framework 1, the lock tongue 112 can freely move in the initial state, and the lock tongue 112 can automatically extend into the lock hole 104 due to the arrangement direction and the shaking in the process of transporting the framework 1, so that the subsequent smooth combination of the lock catch 2 is affected.

In order to avoid the above situation, in this embodiment, a magnet block 115 is further disposed in the bracket 103 and located at the outer side of the accommodating groove 109, and the lock tongue 112 is made of stainless steel, and when the lock tongue 112 is in the initial position, the outer end of the lock tongue 112 is attracted by the magnetic force of the magnet block 115, so that the lock tongue 112 can be stably and reliably kept in the initial position, and displacement of the lock tongue 112 due to gravity or shaking of the lock tongue is avoided.

The elastic gasket 206 in this embodiment is made of porous rubber, and has a porous structure inside, so that the elastic gasket 206 is not easy to harden and has a reduced elasticity after long-term use.

In addition, the upper surface of the cover plate 202 is coated with a wear-resistant coating, and the wear-resistant coating can play a role in protecting the cover plate 202, so that the problem that the cover plate 202 cannot be smoothly sucked by a sucking disc after the surface smoothness is reduced due to scratch is avoided.

Examples

Referring to fig. 9, in this embodiment, an elastic ring 208 is added on the basis of the first embodiment, through holes 207 are symmetrically formed in the petals of the plug 201, the elastic ring 208 passes through two groups of through holes 207, and when the plug 201 is not inserted into the lock hole 104, the elastic ring 208 is in a natural state, i.e., the elastic ring 208 is not stretched. The elastic ring 208 plays a role in assisting force, and when the two groups of petals are far away from each other, the elastic ring 208 is stretched to generate elastic deformation, and the elastic force of the elastic ring 208 can drive the two groups of petals to be close to each other, so that the situation that the two groups of petals cannot be retracted and restored after long-time use can be avoided.

The elastic ring 208 in this embodiment is a rubber band.

The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
