[0023] The following describes the specific implementation of the utility model in detail in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand how to practice the utility model. Although the utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, rather than limiting the scope of the utility model.

[0024] The present application proposes a mother-and-child plug-in sheet for connecting two steel components. For ease of understanding, the two steel components are named as component a and component b respectively. The mother-and-child plug-in sheet comprises: a mother sheet 1 and a child sheet 2. During implementation, the mother sheet 1 can be pre-fixed on component a by spot welding or bolt connection. Similarly, the child sheet 2 can also be pre-fixed on component b by spot welding or bolt connection. During assembly, component a and component b can be connected by plugging and fixing between the mother sheet 1 and the child sheet 2. The mother-and-child plug-in sheet does not require the assistance of professional tools, and can overcome the shortcomings of the prior art that the connection between component a and component b is time-consuming and labor-intensive and the assembly efficiency is low.

[0025] Specific embodiment 1: Please refer to Figure 1-3 The mother sheet 1 comprises a base plate 11 and two L-shaped plates 12. The two L-shaped plates 12 are fixedly arranged at the left and right ends of the base plate 11 in a symmetrical manner. After molding, the left and right ends of the base plate 11 cooperate with the two L-shaped plates 12 to form two identical slots 16; two limit slots (not shown in the figure) are provided on the inner sides of the two L-shaped plates 12;

[0026] Further, a first semicircular groove 13 is provided at the top of the substrate 11, and a square groove 15 is provided at the bottom of the substrate 11. The first semicircular groove 13 and the square groove 15 are provided to facilitate taking the mother sheet 1. When the mother sheet 1 needs to be taken, the thumb can be stuck in the first semicircular groove 13, and the other four fingers can be stuck in the square groove 15. In other preferred schemes, the grooves provided at the top and bottom of the substrate 11 can also be other shapes, which is based on the convenience of manually taking the mother sheet 1.

[0027] Furthermore, a first through hole 14 is provided in the middle of the substrate 11. When the mother sheet 1 needs to be pre-fixed on the component a, a connecting piece such as a screw or a pin can be used to penetrate the first through hole 14 to fix the mother sheet 1 on the component a. Compared with spot welding, the first through hole 14 can improve the fixing efficiency between the mother sheet 1 and the component a. In addition, the number of the first through holes 14 can be increased or decreased depending on the specific usage, and this application does not limit it.

[0028] The sub-piece 2 has an arc-shaped plate 21, a block 22 and a positioning block 23; there are two blocks 22, which are symmetrically arranged at the left and right ends of the arc-shaped plate 21; there are four positioning blocks 23, which are arranged in pairs on the two blocks 22 and are all located at the other end of the connection between the block 22 and the arc-shaped plate 21;

[0029] After plug-in assembly, the sub-piece 2 is located between the two L-shaped plates 12, wherein the two clamping blocks 22 correspond one-to-one to the two clamping slots 16, and the clamping blocks 22 are embedded in the clamping slots 16. At the same time, the clamping blocks 22 are pressed against the base plate 11 and the L-shaped plate 12, and the sub-piece 2 is fixed to the mother piece 1 by a tight fit; in addition, the four positioning blocks 23 correspond one-to-one to the four limiting grooves, and the positioning blocks 23 are at least partially embedded in the limiting grooves;

[0030] Preferably, the positioning block 23 is a ratchet-shaped structure, which can better position the mother sheet 1 and the child sheet 2, and make the mother sheet 1 and the child sheet 2 evenly stressed; through the cooperation between the positioning block 23 and the limiting groove, the components a and b are not easy to separate, and after the connection, the components a and b become a whole, and their tensile and shear resistance can be effectively improved; in addition, the ratchet-shaped structure of the positioning block 23 is conducive to disassembly. When it is necessary to separate the components a and b, it is only necessary to make the components a and b approach each other. The positioning block 23 can easily separate from the limiting groove under the action of external force by virtue of the characteristic of its arc surface being subjected to slow stress, thereby facilitating the separation between the components a and b;

[0031] In this embodiment, the top and bottom of the arc plate 21 are provided with a second semicircular groove 24. The second semicircular groove 24 is provided to facilitate taking the sub-sheet 2. The operation method can refer to the taking of the mother sheet 1.

[0032] Furthermore, the arc plate 21 is composed of a flat plate section 211 and two arc plate sections 212, and the flat plate section 211 is located between the two arc plate sections 212; two second through holes 25 are provided on the flat plate section 211; when the sub-piece 2 needs to be fixed to the component b in advance, fasteners such as screws or pins can be used to penetrate the second through holes 25 to fix the sub-piece 2 to the component b; it should be noted that the flat plate section 211 can increase the contact area between the sub-piece 2 and the component b compared to the arc plate, thereby improving the stability of the sub-piece 2 after being connected to the component b;

[0033] Furthermore, the main plane of the flat plate segment 211 is parallel to the main plane of the base plate 11 , and the arc plate segment 212 allows a space to be left between the flat plate segment 211 and the base plate 11 for accommodating the force-applying part of the fastener, such as a screw head or a pin head.

[0034] Through the technical solution, the mother piece and the child piece are respectively pre-fixed on the two steel components to be assembled, and during assembly, the connection between the components can be completed by simply inserting the child piece on the component into the mother piece on the other component. No professional tools are required during assembly, and the structure of the assembled steel component is stable and firm. The mother-child piece has strong applicability and low cost. Using the mother-child piece to assemble steel components can make the assembly process simple and fast, and improve the assembly efficiency of steel components.

[0035] Specific embodiment 2: Please refer to Figure 4-6 , which is different from the first embodiment, the mother sheet 1 further includes two connecting plates 17, and the two connecting plates 17 are correspondingly arranged in the two card slots 16; the two card blocks 22 are both provided with slots 221; after plug-in assembly, the sub-sheet 2 is located between the two L-shaped plates 12, wherein the two card blocks 22 correspond to the two card slots 16 one by one, the card blocks 22 are embedded in the card slots 16, and the card blocks 22 are pressed against the base plate 11 and the L-shaped plate 12, and the connecting plate 17 is at least partially embedded in the slots 221 at the corresponding position, and the outer periphery of the connecting plate 17 is pressed against the inner wall of the slot 221; by increasing the friction area between the mother sheet 1 and the sub-sheet 2, the stability of the connection between the component a and the component b after assembly can be improved, so that the component a and the component b are not easily separated, and the connection quality is guaranteed.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
