[0022] As Figures 1-5 shown, the embodiment of the utility model is described in detail:

[0023] The automatic key buckle is pressed and includes an arc-shaped plate 1 connected with clothes and a connecting block 8 connected with a key ring. One end of the arc-shaped plate 1 is provided with a base 2, and the base 2 is rotatably connected with the connecting block 8 through a rotating shaft 5 away from the end of the arc-shaped plate 1. Two pressing plates 10 are connected with the base 2. When the connecting block 8 closes the opening end of the arc-shaped plate 1, the two pressing plates 10 can automatically lock the connecting block 8. The locking of the connecting block 8 can be released by pressing the two pressing plates 10 simultaneously.

[0024] In use, the connecting block 8 is rotated on the plate base 2 through the rotating shaft 5, which can realize the opening or closing of the opening end of the arc-shaped plate 1. When the connecting block 8 is rotated to close the opening end of the arc-shaped plate 1, the connecting block 8 is automatically limited and locked by the two pressing plates 10 at this time, so that the arc-shaped plate 1 remains in a closed loop state, which will not fall off from the clothing, and the arc-shaped plate 1 in the closed loop state will not be opened by external force due to the limiting and locking of the connecting block 8 by the two pressing plates 10, thereby achieving the purpose of avoiding opening of the key ring by locking and reducing the risk of losing the key.

[0025] Among them, the clothing generally refers to a belt or a trouser belt.

[0026] Further:

[0027] The middle part of the plate base 2 extends away from the arc-shaped plate 1 end to have a middle seat 3, the connecting block 8 has two ear plates 6 symmetrically protruding thereon, the two ear plates 6 are located on the two sides of the middle seat 3, the rotating shaft 5 penetrates the two ear plates 6 located in the middle seat 3, and the outer sides of the two ear plates 6 are each provided with a clamping groove 7, and the two clamping grooves 7 are respectively used for limiting and connecting the rotating block 8.

[0028] The left and right sides of the plate base 2 are each provided with a recess 4, and the two pressing plates 10 are respectively located in the two recesses 4, and a vertical shaft 11 penetrates between the middle part of the two pressing plates 10 and the plate base 2, so that the pressing plate 10 can rotate in the recess 4.

[0029] The pressing plate 10 is provided with a spring 12 between the end away from the connecting block 8 and the inside of the recess 4.

[0030] The pressing plate 10 is installed in the recess 4 by the vertical shaft 11 penetrating the middle part, can rotate around the vertical shaft 11, and can be pushed away from the middle seat 3 end to the opening direction of the recess 4 by the elastic force of the spring 12, so as to approach the middle seat 3 end to the middle seat 3, and then when the connecting block 8 closes the opening end of the arc-shaped plate 1 and the clamping groove 7 corresponds to the pressing plate 10, the pressing plate 10 slides into the clamping groove 7, the upper and lower side walls inside the clamping groove 7 contact the pressing plate 10, the limiting and locking of the connecting block 8 are formed, the connecting block 8 cannot rotate on the rotating shaft 5, and the locking is realized.

[0031] At the same time, under the influence of the elastic force of the spring 12, when the clamping groove 7 corresponds to the pressing plate 10, the pressing plate 10 will automatically slide into the clamping groove 7 and automatically remain in this state, thereby achieving the purpose of automatic locking;

[0032] When it is needed to open the arc-shaped plate 1, the pressing plate 10 is pressed from the side of the plate base 2 to the inside of the recess 4, so that the pressing plate 10 rotates around the vertical shaft 11 against the elastic force of the spring 12, and the end of the pressing plate 10 slides out of the clamping groove 7, at this time, the connecting block 8 is pushed to rotate around the rotating shaft 5, so that the arc-shaped plate 1 is opened;

[0033] After the connecting block 8 is rotated to open the arc-shaped plate 1, the pressing plate 10 is released, and the pressing plate 10 is automatically rotated and tightly pressed on the side of the connecting block 8 under the influence of the elastic force of the spring 12, until the clamping groove 7 corresponds to the pressing plate 10, the pressing plate 10 automatically slides into the clamping groove 7, and the locking is formed again;

[0034] When locking, the end of the pressing plate 10 inserted into the clamping groove 7 tightly presses the inner wall of the pressing plate 10, at this time, the outer side of the pressing plate 10 is in the same plane as the side of the plate base 2, which not only ensures the beauty of the key ring, but also avoids the hooking of the protruding pressing plate 10 or the protruding edge of the recess 4 with clothes, causing damage or accidental opening of the arc-shaped plate 1, and then causing the loss of the key;

[0035] It should be noted that through the cooperation of the two pressing plates 10 and the two clamping grooves 7, when it is needed to open the arc-shaped plate 1, the two pressing plates 10 and the two clamping grooves 7 need to be separated at the same time, and the connecting block 8 cannot be rotated by separating only one pressing plate 10 and the clamping groove 7, thereby effectively avoiding the accidental rotation of one of the pressing plates 10 to separate from the clamping groove 7, which causes the opening of the arc-shaped plate 1, and greatly avoids the loss of the key caused by the accidental opening of the arc-shaped plate 1.

[0036] Further:

[0037] By providing a semicircular groove on the left and right sides of the plate base 2 away from the corresponding pressing plate 10 of the connecting block 8, the pressing plate 10 can be easily pressed into the recess 4 to open the arc-shaped plate 1 by cooperating with the finger pads.

[0038] Further:

[0039] On the basis of the above embodiment, the arc-shaped plate 1 is made of elastic material, and the arc-shaped plate 1 is provided in a U shape, and the side of the connecting block 8 away from the plate base 2 is attached to the inner side of the arc-shaped plate 1 when the limiting locking is performed;

[0040] By forming a surface-to-surface attachment between the connecting block 8 and the inner side of the arc-shaped plate 1, the opening of the arc-shaped plate 1 can be better closed, and this state can be maintained, so that the pressing plate 10 can be easily slid into the clamping groove 7 to complete the locking.

[0041] Further:

[0042] The arc-shaped plate 1 is made of elastic material, and the protruding part 9 extends from the connecting block 8 to the inside of the arc-shaped plate 1.

[0043] The protruding part 9 is arranged to make the connecting block 8 contact the inside of the arc-shaped plate 1 on both sides of the rotating shaft 5, so that the connecting block 8 can more stably close the opening end of the arc-shaped plate 1, and even when the two pressing plates 10 do not lock the connecting block 8, the connecting block 8 can still have a certain plugging property.

[0044] The elastic property of the arc-shaped plate 1 can be used to rotate the connecting block 8 to press the protruding part 9 against the arc-shaped plate 1, so that the protruding part 9 rotates to the outside of the arc-shaped plate 1, and after the protruding part 9 slides through the arc-shaped plate 1, the arc-shaped plate 1 will automatically recover due to its elastic property.

[0045] Further,

[0046] The protruding part 9 is arranged as a roller that rotates horizontally on the connecting block 8.

[0047] When the connecting block 8 rotates to open the arc-shaped plate 1, the sliding friction between the protruding part 9 and the inside of the arc-shaped plate 1 can be converted into rolling friction, so that the connecting block 8 can more conveniently rotate to open the arc-shaped plate 1.

[0048] Further,

[0049] A sharp end is arranged at the end of the arc-shaped plate 1 away from the connecting block 8, which can be used as a pry tool to increase the use function of the key ring.

[0050] Further,

[0051] A plurality of through holes are arranged horizontally through the connecting block 8.

[0052] The plurality of through holes can be used to connect a plurality of key rings at the same time, improving the applicability.
