[0001] The utility model relates to the technical field of snap fasteners, and more specifically to a snap fastener structure. Background Art

[0002] A snap fastener is a type of button, consisting of four parts. For example, the patent with publication number CN217695454U discloses a snap fastener anti-detachment structure, which relates to the technical field of snap fasteners. The snap fastener anti-detachment structure comprises a sub-button and a mother button, wherein the sub-button and the mother button are respectively provided with a first lining plate and a second lining plate on the side opposite to each other, a clamping rod is provided on the side opposite to the sub-button and the mother button, a clamping hole matched with the clamping rod is provided on the side opposite to the sub-button, and fixing holes are provided on the first lining plate and the sub-button, and on the side opposite to the second lining plate and the mother button.

[0003] The above patent presses the fixing block so that the fixing block shrinks into the inside of the sliding groove, thereby separating the lining plate, the sub-buckle and the mother buckle. However, when the above patent is actually used, the gap between the lining plate, the sub-buckle and the mother buckle is small, and it is difficult for the staff to directly press the fixing block, and it is necessary to use external tools to disassemble it.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a four-button structure is provided to achieve a purpose with greater practical value. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a four-button structure to solve the problems existing in the above background technology.

[0006] The utility model provides the following technical scheme: a four-in-one buckle structure, including a lining plate, a sub-buckle and a mother buckle, the lining plate is set to two, one side of which is provided with a groove, and the other side of the lining plate is fixedly installed with a cone column, the sub-buckle and the mother buckle are provided with a cone groove corresponding to the cone column on the surface of the sub-buckle and the mother buckle, and a rotating block is rotatably installed in the groove, one side of the rotating block is fixedly installed with a rotating shaft, the rotating shaft rotates and penetrates into the cone column, and the deep end of the rotating shaft is fixedly installed with a rotating disk, the eccentric part of the rotating disk is fixedly installed with two symmetrical two rotating shafts, the outer sides of the two rotating shafts are rotatably installed with connecting blocks, one end of the connecting block is provided with a locking rod, the connecting block and the locking rod are rotatably connected by three rotating shafts, the locking rods slide through the cone column, the sub-buckle and the mother buckle are provided with locking grooves corresponding to the locking rod, the outer side of the locking rod is fixedly installed with a push plate, the push plate is slidably set on the inner wall of the cone column, and one side of the push plate is fixedly installed with a spring.

[0007] Furthermore, two symmetrical positioning blocks are fixedly installed on the conical end faces of the cone column, and positioning grooves corresponding to the positioning blocks are opened in the conical grooves of the sub-buckle and the mother buckle. Through the two positioning blocks, the locking grooves at the corresponding positions of the locking rod and the sub-buckle and the mother buckle are positioned, so that the locking rod can be quickly inserted into the corresponding locking groove position of the sub-buckle or the mother buckle.

[0008] Furthermore, elastic rubber rings are fixedly installed in the locking grooves of the sub-buckle and the mother buckle, and the connection stability between the locking rod and the sub-buckle and the mother buckle is improved through the elastic rubber ring, thereby avoiding abnormal noise caused by the slow movement after the connection between the lining plate and the sub-buckle and the lining plate and the mother buckle, affecting the user experience.

[0009] Furthermore, the locking end of the locking rod is arranged to be in an arc shape. By arranging the locking end of the locking rod to be in an arc shape, the locking rod can slide quickly along the arc end surface, thereby being quickly inserted into the locking groove position corresponding to the sub-buckle and the mother buckle.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Example 1: Please refer to Figure 1-4 The utility model provides a snap-on structure, including a lining plate 100, a sub-button 101, and a mother button 102. The number of lining plates 100 is set to two, one side of which is provided with a groove, and the other side of the lining plate 100 is fixedly installed with a cone column 109. The surfaces of the sub-button 101 and the mother button 102 are provided with a cone groove corresponding to the cone column 109, and a rotating block 110 is rotatably installed in the groove. A rotating shaft 111 is fixedly installed on one side of the rotating block 110, and the rotating shaft 111 rotates deep into the cone column 109. A rotating disk 112 is fixedly installed at the deep end of the rotating shaft 111, and the eccentric position of the rotating disk 112 Two symmetrical rotating shafts 113 are fixedly installed, and connecting blocks 114 are rotatably installed on the outer sides of the two rotating shafts 113. A locking rod 116 is provided at one end of the connecting block 114. The connecting block 114 and the locking rod 116 are rotatably connected through three rotating shafts 115. The locking rods 116 slide through the cone column 109. The sub-buckle 101 and the mother buckle 102 are provided with locking grooves corresponding to the locking rods 116. Push plates 117 are fixedly installed on the outer sides of the locking rods 116. The push plates 117 are slidably set on the inner wall of the cone column 109, and a spring 118 is fixedly installed on one side of the push plates 117.

[0022] Working principle: When in use, the corresponding clothing is penetrated through the conical end face of the cone column 109, and then the rotating block 110 is rotated, and the rotating disk 112 is driven to rotate by a rotating shaft 111 on the rotating block 110. When the rotating disk 112 rotates, the second rotating shaft 113 at the eccentric position on the rotating disk 112 will pull the locking rod 116 through the connecting block 114 and the third rotating shaft 115, so that the penetrating end of the locking rod 116 is retracted into the inner wall of the cone column 109. At this time, the locking rod 116 will drive the push plate 117 to compress the spring 118, and then the conical groove surfaces of the sub-button 101 and the mother buckle 102 are respectively aligned with the two cone columns 109 to fit. When the sub-buckle 101, the mother buckle 102 and the cone column 109 move to the appropriate position, the rotating block 110 is released. At this time, the restoring force of the spring 118 will push the locking rod 116 through the push plate 117, so that the locking rod 116 is inserted into the corresponding locking grooves of the sub-buckle 101 and the mother buckle 102, thereby fixing the position between the lining plate 100 and the sub-buckle 101 and the lining plate 100 and the mother buckle 102. When it is necessary to disassemble the lining plate 100 and the sub-buckle 101 and the lining plate 100 and the mother buckle 102, the rotating block 110 is rotated in the same way to retract the locking rod 116 into the inner wall of the cone column 109.

[0023] Embodiment 2:

[0024] The difference between the second embodiment and the first embodiment lies in that two symmetrical positioning blocks 120 are fixedly installed on the conical end faces of the conical column 109, positioning grooves corresponding to the positioning blocks 120 are opened in the conical grooves of the sub-buckle 101 and the mother buckle 102, elastic rubber rings 121 are fixedly installed in the locking grooves of the sub-buckle 101 and the mother buckle 102, the locking end of the locking rod 116 is arranged in an arc shape, the rotating block 110 is flush with the surface of the lining plate 100, and the outer surfaces of the lining plate 100, the sub-buckle 101 and the mother buckle 102 are all provided with anti-slip grooves.

[0025] When in use, the positions of the locking rod 116 and the corresponding locking grooves on the sub-buckle 101 and the mother buckle 102 are positioned by the positioning block 120. When the locking rod 116 is inserted into the corresponding locking grooves of the sub-buckle 101 and the mother buckle 102 respectively, the elastic rubber ring 121 is used to block the gaps in the locking grooves of the locking rod 116 and the sub-buckle 101 and the mother buckle 102, thereby avoiding abnormal noise in the fixed connection between the lining plate 100 and the sub-buckle 101 and the lining plate 100 and the mother buckle 102. By setting the locking end of the locking rod 116 to an arc shape, the locking rod 116 can be quickly inserted into the corresponding position along the arc surface. The anti-slip grooves on the outside of the lining plate 100, the sub-buckle 101 and the mother buckle 102 increase the friction between the staff's hands and the object. By making the rotating block 110 and the surface of the lining plate 100 flush, the appearance of the device is improved.

[0026] Finally: The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
