[0029] The tapered platform 221 of the pull rod 22 and the inner wall between the bottom of pull violent pair of buckles 21 are provided with spring 23 (that is, one end of spring 23 is in abutment with the inner bottom wall of pull violent pair of buckles 21, and the other end is in abutment with the tapered platform 221 of pull rod 22), and the pull rod 22 can be telescopic inside and outside under the action of spring 23, that is, the pull rod 22 can prop open pull violent pair of buckles 21 through the tapered platform 221 when being subjected to tension, and can completely retract into the inside of pull violent pair of buckles 21 by overcoming the resistance of spring 23 when being subjected to the pressure of stop face 111,

[0030] The pull-explosion pair buckle 21 includes a first expansion shell and a second expansion shell, which are combined in a pair buckle manner outside the pull rod 22 (a clamping tooth 211 extending in the circumferential direction is arranged on the abutting surface of the first expansion shell, and a clamping tooth groove 212 matched with the clamping tooth 211 is arranged on the abutting surface of the second expansion shell), forming a cylindrical structure with one end sealed, and a limiting table 213 for limiting the conical table 221 is arranged on the inner wall of the expansion shell, the surface of the limiting table 213 in contact with the conical table 221 of the pull rod 22 is an arc surface, and the surface in contact with the rod cap 222 of the pull rod 22 is a horizontal surface, and the pull rod 22 can be expanded to pull the pull-explosion pair buckle 21 when subjected to a pulling force through the conical table 221.

[0031] In the embodiment, the outer walls of the double-pass buckle 1 and the pull-explosion buckle 2 are both provided with auxiliary positioning teeth 3.

[0032] The working principle of the above structure is as follows:

[0033] During installation, first, the pull rod 22 and the spring 23 are put into the pull-explosion pair buckle 21 to assemble the pull-explosion buckle 2, and the rod cap 222 end of the pull rod 22 is stretched out to the outside of the pull-explosion pair buckle 21 under the action of the spring 23; then the pull-explosion buckle 2 and the double-pass buckle 1 are respectively installed into the reserved holes of the two plates; at this time, any plate can be slid from any direction (up, down, left, right) to push the rod cap 222 into the space between the two positioning teeth 13 through the sliding groove 11 of any one end of the double-pass buckle 1 to complete the connection of the two plates, and the invisible buckle is completely embedded in the inside of the plate, and there is no exposed hole or screw on the surface after installation, which takes into account the aesthetics and structural strength, and moreover, due to the extrusion of the pull rod 22 to the pull-explosion table 12, the double-pass buckle 1 is expanded to the two sides, so that the double-pass buckle 1 is fixed more firmly with the plate; after connection, any plate is pulled to move the conical table 221 to the top of the pull-explosion pair buckle 21, and due to the limiting of the limiting table 213, a large positive pressure is formed on the outer circumferential surface of the pull-explosion pair buckle 21, so that the first expansion shell and the second expansion shell are expanded and pulled to be exploded by the conical table 221, achieving the fixing effect of the pull-explosion buckle 2 and the plate. When disassembling, any plate is slid to push the pull rod 22 out of the sliding groove 11 through the inclined stop surface 111.

[0034] When in use, the space is adjusted by the pull rod type, and the space extrusion is relied on to adjust the extension and contraction of the pull rod 22. When the plate vibrates or shakes, external assistance is generated, and the external vibration assistance will pull the pull rod 22 based on the principle of mechanics to trigger the expansion of the conical table 221 to the pull-explosion pair buckle 21; when the force is released, the space extrusion will trigger the rebound and contraction of the conical table 221 of the pull rod 22, and then the gap between the plates is adjusted automatically. The space adjustment is more flexible and has a wider range.

[0035] Through the setting of the double-pass buckle, not only the invisible connection between the plates is realized, but also the installer does not need to consider the installation position, installation direction, installation sequence and installation method when installing, and the designer does not need to consider the installation position, installation direction, installation sequence and installation method when designing, two-way arbitrary assembly and disassembly, installation is more flexible and convenient, not limited by space direction, design is more convenient, simplifies the plate assembly process, and improves work efficiency; through the setting of the pull rod cone table-spring, mechanical principle is applied to cooperatively adjust the space in the fixed space, and the elastic reset function can be activated in the transportation and application process, elastic deformation is allowed under the action of vibration, shaking or external force, gap change is compensated, and after the external force disappears, the space is extruded and the spring rebounds to quickly automatically restore to the original occlusion state, the problems that the traditional pull explosion structure is easy to loosen in the vibration environment and the gap is irreversible are solved, and the connection scene with higher requirements for appearance and dynamic stability can be better adapted.

[0036] The above is only the preferred embodiment of the utility model, and is not used for limiting the utility model, for the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
