[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Example 1

[0032] The present application embodiment discloses a keel connector, referring to Figure 1 and Figure 2, including an upper connecting part 1 and a lower connecting part 2. The upper connecting part 1 includes an A panel 11 and a B panel 12, and the lower connecting part 2 includes a C panel 21 and a D panel 22. The A panel 11 and the B panel 12, and the C panel 21 and the D panel 22 are arranged at right angles. A holder 3 is arranged on each of the A panel 11 and the D panel 22. The holder 3 includes two symmetrically arranged semicircular buckles 31, and both sides of the semicircular buckles 31 are provided with semicircular notches to form a buckle opening 32. The holder 3 is used to connect with the keel. The shape of the semicircular buckle 31 is set to be semicircular. This setting can improve the connection strength of the semicircular buckle 31 and can be adapted to the shape of the keel. The holder 3 is fixedly connected to the keel by the setting of the buckle opening 32. The shape of the buckle opening 32 is set to be semicircular, and an arc-shaped contact surface can be formed between the holder 3 and the keel. When connected with the keel, the clamping part of the keel can be slid into the buckle opening 32 to form a clamping fixation, which simplifies the fixing method.

[0033] The upper connecting part 1 and the lower connecting part 2 are each configured as an integral part, and the upper connecting part 1 and the lower connecting part 2 further include a folding edge 4, and the folding edges 4 on the upper connecting part 1 and the lower connecting part 2 are arranged in opposite directions. The upper connecting part 1 and the lower connecting part 2 are each configured as an integral part, which facilitates the integral processing and forming of the upper connecting part 1 and the lower connecting part 2, and the upper connecting part 1 and the lower connecting part 2 are both configured as aluminum alloy. The configuration of the folding edge 4 can improve the bending resistance of the upper connecting part 1 and the lower connecting part 2.

[0034] The upper connecting part 1 and the lower connecting part 2 are arranged in a Z shape, and the B panel 12 and the C panel 21 are arranged as two fitting surfaces that cooperate with each other. Adjustment mechanisms are provided on the B panel 12 and the C panel 21, and the B panel 12 and the C panel 21 are connected through the adjustment mechanism. The adjustment mechanism is used to fix the position between the upper connecting part 1 and the lower connecting part 2 and adjust the length between the upper connecting part 1 and the lower connecting part 2. The adjustment mechanism improves the overall applicability of the connecting piece.

[0035] The adjustment mechanism includes a nut fixing hole 51, an adjustment bolt 53, an adjustment nut 54 and an adjustment slot 52. The adjustment slot 52 is vertically opened in the middle of the C panel 21, and the shape of the adjustment slot 52 is set to be a long slot. The adjustment bolt 53 and the adjustment nut 54 are threadedly connected to thread the upper connecting part 1 and the lower connecting part 2. In the embodiment of the present application, two nut fixing holes 51 are opened in the upper and lower parts.

[0036] The implementation principle of Example 1 is: the keel is fixed to the connecting piece through the snap-fit ​​opening 32, and the position between the upper connecting part 1 and the lower connecting part 2 is adjusted through the adjustment slot 52, so as to achieve length adjustment. Two nut fixing holes 51 are provided above and below, which can provide a larger adjustment range for the upper connecting part 1 and the lower connecting part 2.

[0037] Example 2

[0038] Reference Figure 3 The shape of the adjustment groove 52 can also be set to an E-shaped groove.

[0039] The implementation principle of Example 2 is as follows: the keel is fixed to the connector through the snap-fit ​​opening 32, and the adjusting bolt 53 is clamped in the position of the transverse groove of the E-shaped groove, so that the adjusting bolt 53 and the adjusting nut 54 can be prevented from sliding due to vibration or other reasons, thereby improving the fixing firmness. When adjusting the length, it is not necessary to disassemble the adjusting bolt 53 and the adjusting nut 54, but only to loosen the relative position of the adjusting bolt 53 and the adjusting nut 54, and slide and adjust through the vertical groove position of the E-shaped groove, and then fix up and down after sliding to the transverse groove position. There are two nut fixing holes 51 in the upper and lower parts, which can provide a larger adjustment range for the upper connecting part 1 and the lower connecting part 2.

[0040] Example 3

[0041] Reference Figure 4 and Figure 5 The adjusting groove 52 can also be set as a fishbone-shaped groove, and a latching portion 552 is fixedly provided on the adjusting bolt 53. The latching portion 552 is a rectangular block oppositely provided on both sides of the adjusting bolt 53. A circular pad surface 561 is provided on the adjusting nut 54, and the groove width of the fishbone-shaped groove is matched with the latching portion 552. In the embodiment of the present application, three nut fixing holes 51 are provided.

[0042] The implementation principle of Example 3 is as follows: the keel is fixed to the connecting piece through the snap-fit ​​opening 32, the upper connecting part 1 and the lower connecting part 2 are fixed through the locking bolt, the shape of the adjustment groove 52 is set to a fishbone-shaped groove, and the shape of the fishbone-shaped groove makes the adjustment groove 52 and the locking part 552 cooperate with each other. When the adjustment nut 54 is inserted into the adjustment groove 52, the locking part 552 is snapped into the adjustment groove 52 to form a snap-fit ​​limit by tightening the adjustment bolt 53 and the adjustment nut 54.

[0043] The above-mentioned embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several deformations and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
