[0003] A Chinese patent with application number 202123158973.2 discloses an anti-deformation high-fitting plate connector, including a first connecting plate, a second connecting plate and a third connecting plate. The first connecting plate and the second connecting plate are arranged in parallel, one end of the third connecting plate is connected to the first connecting plate, and the other end is connected to the second connecting plate. The inner sides of the first connecting plate and the second connecting plate are both provided with buckles, and the third connecting plate is provided with a first connecting hole.

[0004] This application involves screwing the screw into the second plate and then clamping the screw into the connecting plate, which can easily cause the connector and the first plate to separate, resulting in a poor connection effect.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0006] In order to achieve a quick and stable connection between two plates, the present application provides a deformation-resistant and highly-fitting plate connector.

[0007] The present application provides a deformation-resistant and highly conformable plate connector, which adopts the following technical solution:

[0008] A deformation-resistant and highly-fitting plate connector comprises a connector body for connecting two plates, grooves for placing the two plates are arranged on two sides of the connector body, and the upper and lower sides of the grooves are open, a diamond-shaped through hole is arranged on the upper end face of the connector, the diamond-shaped through hole is connected along the upper and lower sides of the connector, a plurality of arc-shaped plates are arranged in the diamond-shaped through hole, and the plurality of arc-shaped plates are arranged circumferentially along the axis of the diamond-shaped through hole, one side of the arc-shaped plate abuts against the inner wall of the diamond-shaped through hole, and a thread is arranged on the side of the arc-shaped plate close to the axis of the diamond-shaped through hole.

[0009] By adopting the above technical solution, the two plates to be connected are respectively inserted into the two grooves of the connecting piece, the two arc-shaped plates are placed in the diamond-shaped grooves of the connecting piece, and screw threads of appropriate sizes are installed between the two arc-shaped plates. Through the mutual cooperation between the screws and the arc-shaped plates, the connecting piece is deformed, and the two side walls of the groove are brought close to each other to clamp the plates.

[0010] Optionally, two side walls of the groove are first inclined surfaces, and the two first inclined surfaces are inclined away from the edge of the diamond-shaped through hole and away from each other.

[0011] By adopting the above technical solution, the opening of the groove away from the diamond-shaped through hole is enlarged, which makes it easier for the plate to be inserted into the groove. At the same time, during the deformation of the connecting member, the two first inclined surfaces rotate with the connecting member to be parallel to each other, thereby enhancing the connection stability of the connecting member to the plate.

[0012] Optionally, there are two arc-shaped plates, connecting plates are provided on both sides of the arc-shaped plates, both side edges of the connecting plates are respectively fixedly connected to the two arc-shaped plates, and the connecting plates are clamped in the diagonal areas of the diamond-shaped through holes.

[0013] By adopting the above technical solution, the two arc plates are connected by a connecting plate, and the connecting plate and the arc plate are inserted into the diamond groove together. The connecting plate is correspondingly clamped in the two opposite corners of the diamond through hole to achieve the positioning effect of the arc plate. In the process of connecting the screws and the arc plate, the stability of the arc plate is improved.

[0014] Optionally: a first limit block is provided on the inner wall of the upper end of the groove.

[0015] By adopting the above technical solution, it is convenient to quickly locate the position of the connecting piece.

[0016] Optionally: A second limiting block for limiting the arc plate is provided on the lower end side wall of the diamond-shaped through hole.

[0017] By adopting the above technical solution, when the arc-shaped plate is inserted into the diamond-shaped through hole, it is convenient to quickly position the arc-shaped plate.

[0018] Optionally: the inner wall of the groove is a rough surface.

[0019] By adopting the above technical solution, the friction between the side wall of the groove and the plate is increased, and the connection stability between the connecting piece and the plate is improved.

[0020] Optionally, the spacing between the diamond-shaped through holes and the grooves is 0.3-0.6 cm.

[0021] By adopting the above technical solution, when the spacing between the diamond through holes and the grooves is too large, it will be more difficult for the connector to deform, affecting the clamping effect of the connector on the plate. When the spacing between the diamond through holes and the grooves is too small, the connector is prone to breakage, affecting the service life of the connector.

[0022] Optionally, the angles of the two diagonals of the diamond-shaped through hole close to the groove are between 30° and 60°.

[0023] By adopting the above technical solution, the two diagonal angles of the diamond through hole are restricted. When the two diagonal angles of the diamond through hole close to the groove are too large, the connector is difficult to deform, wasting manpower costs. When the two diagonal angles of the diamond through hole close to the groove are too small, the connector is insufficiently deformed, resulting in poor clamping effect of the connector on the plate.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The present application provides grooves for clamping the plates on both sides of the connecting piece, and by threading the screws into the diamond-shaped through holes, the two plates can be quickly and stably connected by utilizing the deformation of the connecting piece;

[0026] 2. By setting a connecting plate between two arc-shaped plates and setting a second limit block in the diamond-shaped through groove, it is convenient to quickly position the arc-shaped plates and improve the efficiency of connecting the plates by the staff;

[0027] 3. By setting the two side walls of the groove as rough inclined surfaces, the connection effect of the connecting piece on the plate is further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.

[0033] The present application discloses a plate 1 connecting member 2, such as Figure 1and Figure 2 As shown, it includes a connector 2 for connecting a plate 1, and grooves 21 for placing the plate 1 are arranged on both sides of the connector. The upper and lower end faces of the connector 2 are penetrated with diamond-shaped through holes 22, and the diagonal of the diamond-shaped through holes 22 is parallel to the length direction of the upper end face of the connector 2. The grooves 21 on both sides of the connector are arranged in the vertical direction, and the upper and lower sides of the grooves 21 are arranged with openings. In order to facilitate the insertion of the plate 1 into the grooves 21, and to improve the fit between the side walls of the grooves 21 and the plate 1, the two side walls of the grooves 21 are first inclined surfaces 211, and the two first inclined surfaces 211 are arranged to be inclined away from the two first inclined surfaces 211. In order to facilitate the positioning of the position of the connector 2, the upper inner walls of the grooves 21 on both sides of the connector 2 are provided with first limit blocks 212, and the first limit blocks 212 abut against the upper end face of the plate 1.

[0034] like Figure 2 and Figure 3 As shown, a screw 4 and two arc plates 3 are arranged in the diamond through hole 22. The radius of the selected screw should be slightly larger than the shortest distance between the axis of the diamond through hole 22 and the inner wall of the diamond through hole 22. The two arc plates 3 are mirrored along the vertical plane where the longer diagonal of the diamond through hole 22 is located. The two arc plates 3 are respectively abutted against the inner wall of the diamond through hole 22 on one side away from each other. The two arc plates 3 are provided with threads for matching and connecting with the screw 4 on the side close to the axis of the diamond through hole 22. By rotating the screw 4 and connecting it between the two arc plates 3, the diamond through hole 22 is deformed by the extrusion between the screw 4 and the arc plate 3, so that the inside of the diamond through hole 22 expands outward, and the side walls of the two grooves 21 clamp the side walls of the plate 1 accordingly. In order to enhance the friction between the inner wall of the groove 21 and the plate 1 and extend the service life of the connector 2, the inner wall of the groove 21 is set to a rough surface. In order to prevent the connector 2 from breaking and ensure the clamping effect of the connector 2 on the plate 1, the spacing between the diamond through hole 22 and the groove 21 is 0.3-0.6 cm. In order to prevent the connector 2 from being difficult to deform and wasting manpower costs when the angles of the two diagonals of the diamond through hole 22 close to the groove 21 are too large, and the connector 2 is not deformed enough when the angles of the two diagonals of the diamond through hole 22 close to the groove 21 are too small, resulting in poor clamping effect of the connector 2 on the plate 1, the angles of the two diagonals of the diamond through hole 22 close to the groove 21 are between 30°-60°.

[0035] like Figure 2 and Figure 3As shown, in order to reduce the influence of the deformation of the diamond through hole 22 on the arc plate 3, the arc plate 3 is made of hard PVE material to ensure the connection stability between the arc plate 3 and the screw 4. Connecting plates 31 are arranged on both sides of the arc plate 3, and the edges of the two sides of the connecting plate 31 are respectively fixedly connected to the two arc plates 3. For the convenience of processing, the connecting plate 31 and the two arc plates 3 are an integrally formed structure. In order to enhance the stability of the arc plate 3, the connecting plate 31 is clamped in the diagonal of the diamond through hole 22 to limit the position of the arc plate 3, so as to facilitate the subsequent connection processing of the arc plate 3 and the screw 4.

[0036] like Figure 2 As shown, in order to facilitate the positioning of the arc plate 3, four second limit blocks 23 are arranged on the lower end side wall of the diamond through hole 22, and the four second limit blocks 23 are respectively fixed on the four side walls of the diamond through hole 22, and the four second limit blocks 23 are arranged circumferentially along the axis of the diamond through hole 22. When the arc plate 3 is inserted into the diamond through hole 22, the arc plate 3 is abutted against the upper end surface of the second limit block 23, so that the arc plate 3 can be quickly positioned, thereby improving the construction efficiency of the staff.

[0037] The implementation principle of this embodiment is:

[0038] By correspondingly inserting the two plates 1 into the two grooves 21 of the connecting member 2, the two first limit blocks 212 are respectively abutted against the two plates 1, the arc plate 3 is placed in the diamond through hole 22 of the connecting member 2, so that the arc plate 3 abuts against the second limit block 23, and the screw 4 is threadedly connected to the two arc plates 3. During the rotation of the screw 4, the screw 4 and the arc plate 3 cooperate with each other, driving the connecting member 2 to deform, causing the interior of the diamond through hole 22 to expand outward, and driving the two side walls of the groove 21 to clamp the plate 1, thereby achieving the connection effect of the two plates 1.

[0039] The embodiments of the implementation methods are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
