In order to realize the purpose, the following technical scheme is provided:

the back plate buckle is characterized by comprising a connecting rod and a head arranged at one end of the connecting rod, wherein the head is in a cam shape, an installation groove for screwing the back plate buckle is formed in the end face, far away from one end of the connecting rod, of the head, the outer periphery of the head comprises a first peripheral section, a second peripheral section and a third peripheral section which are sequentially connected, the distance from the second peripheral section to the rotation center of the head is larger than the distance from the first peripheral section to the rotation center of the head, the distance from the third peripheral section to the rotation center of the head is larger than or equal to the distance from the second peripheral section to the rotation center of the head, and at least one ratchet is arranged on the second peripheral section.

Optionally, the distances from the first peripheral section, the second peripheral section and the third peripheral section to the head rotation center increase in sequence.

Optionally, the mounting groove is a cross groove, a cross groove or a star groove.

Optionally, the third peripheral section is arc-shaped.

Optionally, the outer periphery of the head further includes a limiting portion disposed between the first peripheral section and the third peripheral section.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the back plate buckle of the utility model can tightly clamp the back plate, so that the connection between the back plate and other plates is firm; the second peripheral section of the back plate buckle is provided with a plurality of ratchets, when the back plate buckle is rotated, the ratchets on the back plate buckle cut the surface of the back plate, and a groove is formed in the surface of the back plate and can prevent the back plate buckle from loosening and falling off; for a harder backboard, the ratchet on the backboard buckle can open a groove on the harder backboard more easily when rotating, and the opened groove is not easy to expose the edge, thereby ensuring the attractive appearance.

Detailed Description

Embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the back plate buckle provided by the utility model comprises a connecting rod 2 and a head 1 arranged at one end of the connecting rod 2. The head 1 is cam-shaped, that is, the distance from the outer periphery of the head 1 to its center of rotation is varied. The end face, far away from one end of the connecting rod 2, of the head part 1 is provided with a mounting groove 10 for screwing the back plate buckle. The mounting slot 10 may be a cross slot, a star slot or other suitable shape. The outer periphery of the head 1 comprises a first peripheral section 11, a second peripheral section 12 and a third peripheral section 13 which are connected in sequence. The distance from the second peripheral section 12 to the rotation center of the head 1 is greater than the distance from the first peripheral section 11 to the rotation center of the head 1, the distance from the third peripheral section 13 to the rotation center of the head 1 is greater than or equal to the distance from the second peripheral section 12 to the rotation center of the head 1, and a plurality of ratchet teeth 120 are arranged on the second peripheral section 12.

Preferably, the distances from the first peripheral section 11, the second peripheral section 12 and the third peripheral section 13 to the rotation center of the head 1 increase in order.

When the back board fastener is turned with a screwdriver aligned with the mounting groove 10, the head 1 is rotated around the center point of the mounting groove 10, and at the same time, the entire back board fastener is rotated around the rotation center line of the connecting rod 2. The utility model discloses the title "head 1 rotation center" refers to the rotation center line of connecting rod 2.

Referring to fig. 3 and 4, fig. 3 and 4 show the installation process of the back plate buckle of the present invention. A hole is previously punched in the plate material 02 to be coupled with the back plate 01. During installation, the back plate 01 is inserted into the caulking groove 4 of the plate 02 in an aligning way; the first peripheral section 11 of the head part 1 faces the backboard 01, and the backboard is buckled into the mounting hole 3 of the plate 02; the cross-shaped screwdriver head is screwed to align with the cross-shaped groove of the head 1, so that the head 1 rotates, the ratchet teeth 120 of the second peripheral section 12 start to cut the back plate 01, a groove is formed in the back plate 01, and when the third peripheral section 13 of the head 1 faces the back plate 01, the third peripheral section 13 of the head 1 is embedded into the groove of the back plate 01, so that the back plate 01 is clamped, and the back plate is prevented from loosening.

The utility model has the advantages that: the third peripheral section 13 of the back plate buckle is in interference fit with the back plate, so that the back plate is clamped tightly, and the back plate is prevented from loosening; the second peripheral section 12 of the back plate buckle is provided with a plurality of ratchets 120, when the back plate buckle is rotated, the ratchets 120 on the back plate buckle cut the surface of the back plate 01, and a groove is formed in the surface of the back plate 01 and can prevent the back plate buckle from loosening and falling off; for a harder backboard, the ratchet teeth 120 on the backboard buckle can be more easily grooved on the harder backboard when rotating, and the grooved groove is not easy to expose, thereby ensuring the attractive appearance.

Preferably, the third peripheral section 13 has a circular arc shape.

The outer periphery of the head 1 further comprises a limiting part 14 arranged between the first peripheral section 11 and the third peripheral section 13, and the distance from the limiting part 14 to the rotation center of the head 1 is greater than the distance from the third peripheral section 13 to the rotation center of the head 1. The limiting part 14 can prevent the back board buckle from being twisted in place or being twisted over.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
