The bottom end of the trapezoidal lead screw penetrates through the lower nail body and is connected with an external hexagonal cylinder, and a lead screw nut is arranged on the outside of the trapezoidal lead screw. The surface of the lead screw nut is connected with a first scissor arm through a rotating shaft, and the other end of the first scissor arm is connected with a support member through a rotating shaft. A chute is arranged on the surface of the support member, and a sliding pin is arranged in the chute. The front end of the sliding pin is connected with a second scissor arm through a rotating shaft.

[0007] Further, the side surface of the upper nail body is in an inverted concave structure, and the upper nail body and the lower nail body are of an integrated structure.

[0008] Further, the bottom of the lower nail body is connected with an internal hexagonal cylinder, and a nail head is arranged at the top of the upper nail body.

[0009] Further, the upper nail body, the trapezoidal lead screw, and the internal hexagonal cylinder are coaxially arranged. The external hexagonal cylinder is located in the middle of the internal hexagonal cylinder, and the external hexagonal cylinder accounts for one-half of the height of the external hexagonal cylinder.

[0010] Further, the middle part of the first scissors arm is rotationally connected to the second scissors arm through a rotating shaft, and one end of the second scissors arm far from the sliding pin is rotationally connected to the upper nail body through a rotating shaft.

[0011] Further, the support member has an L-shaped structure, and there are two of each of the first scissors arm, the support member, the chute, the sliding pin, and the second scissors arm.

[0012] The utility model provides a connection assembly for a steel lining and a screwed member, having the following beneficial effects:

[0019] The following further describes in detail the embodiments of the utility model with reference to the drawings and embodiments. The following embodiments are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0020] Such as Figures 1 to 3As shown in the figure, a connecting component for a steel lining and a screwed part includes an upper nail body 1 and a reinforcement component 5. Notches 2 are provided on both sides of the upper nail body 1, and a lower nail body 3 is arranged at the bottom of the upper nail body 1. The side surface of the upper nail body 1 is in an inverted concave structure, and the upper nail body 1 and the lower nail body 3 are of an integral structure. The reinforcement component 5 is arranged in the bearing at the middle end of the top of the lower nail body 3, and the reinforcement component 5 includes a trapezoidal lead screw 501, an external hexagonal cylinder 502, a lead screw nut 503, a first scissors arm 504, a support member 505, a chute 506, a sliding pin 507 and a second scissors arm 508. The bottom end of the trapezoidal lead screw 501 passes through the lower nail body 3 and is connected to the external hexagonal cylinder 502, and a lead screw nut 503 is arranged outside the trapezoidal lead screw 501. The surface of the lead screw nut 503 is connected to the first scissors arm 504 through a rotating shaft, and the other end of the first scissors arm 504 is connected to the support member 505 through a rotating shaft. A chute 506 is provided on the surface of the support member 505, and a sliding pin 507 is arranged in the chute 506. The front end of the sliding pin 507 is connected to the second scissors arm 508 through a rotating shaft. The middle part of the first scissors arm 504 is rotationally connected to the second scissors arm 508 through a rotating shaft, and the end of the second scissors arm 508 far from the sliding pin 507 is rotationally connected to the upper nail body 1 through a rotating shaft. The support member 505 is in an L-shaped structure, and two of each of the first scissors arm 504, the support member 505, the chute 506, the sliding pin 507 and the second scissors arm 508 are provided.

[0021] The specific operation is as follows. By rotating the external hexagonal cylinder 502, the lead screw nut 503 makes a longitudinal displacement along the outside of the trapezoidal lead screw 501. At the same time, the sliding pin 507 slides in the chute 506 on the surface of the support member 505 to change the crossing angle of the first scissors arm 504 and the second scissors arm 508, so that the support member 505 moves away from the trapezoidal lead screw 501 until the support member 505 protrudes out of the notch 2 to better limit the position of the upper nail body 1 and achieve the effect of not being easily loosened.

[0022] As Figure 1 and Figure 2 shown in the figure, an internal hexagonal cylinder 4 is connected to the bottom of the lower nail body 3, and a nail head 6 is arranged at the top of the upper nail body 1. The upper nail body 1, the trapezoidal lead screw 501 and the internal hexagonal cylinder 4 are coaxially arranged. The external hexagonal cylinder 502 is located in the middle of the internal hexagonal cylinder 4, and the external hexagonal cylinder 502 accounts for one-half of the height of the external hexagonal cylinder 502.

[0023] The specific operation is as follows. The internal hexagonal cylinder 4 and the external hexagonal cylinder 502 are coaxially arranged, and the outer diameter of the external hexagonal cylinder 502 is smaller than the inner diameter of the internal hexagonal cylinder 4, so as to meet the conditions of respectively using an internal hexagonal wrench and a socket wrench to rotate the internal hexagonal cylinder 4 and the external hexagonal cylinder 502, reducing the operation difficulty for connecting the steel lining and the middle brace screwed part.

[0024] In summary, for the connecting component between the steel lining and the screwed part, during use, first, the nail head 6, the upper nail body 1, the lower nail body 3, and the internal hexagonal cylinder 4 are integrally coaxially arranged from top to bottom. Select a tool with a suitable size, place the internal hexagonal wrench in the internal hexagonal cylinder 4, and insert this integrated structure into the through holes of the steel lining and the middle muntin screwed part with the help of the internal hexagonal wrench.

[0025] Subsequently, remove the internal hexagonal wrench, select a tool with a suitable size, place the socket wrench on the outside of the external hexagonal cylinder 502 in the internal hexagonal cylinder 4, and rotate the external hexagonal cylinder 502 and the trapezoidal lead screw 501 by turning the internal hexagonal wrench.

[0026] At this time, the lead screw nut 503 moves vertically upward along the outside of the trapezoidal lead screw 501, and at the same time, the sliding pin 507 slides upward in the surface chute 506 of the support member 505. By the synchronous displacement of the lead screw nut 503 and the sliding pin 507, the support angles of the first scissors arm 504 and the second scissors arm 508 with respect to the support member 505 are changed, so that the two symmetrically distributed support members 505 move away from the trapezoidal lead screw 501 at the same time, that is, the support members 505 protrude from the notch 2 and then abut against the steel lining and the middle muntin screwed part. Thus, the friction force is enhanced through the support members 505, the position of this integrated structure is further limited and strengthened, loosening is prevented, and the firmness of the connection between the steel lining and the middle muntin screwed part is ensured.
