Description

Pre-assembled elastic inner seat with quick assembly and high strength

The invention relates to a pre-assembled elastic inner seat which combines assembly quick assembly and high strength, and particularly relates to an elastic inner seat structure which effectively simplifies assembly steps and improves assembly strength.

The C-shaped steel I used in the general solar panel brackets of the industry mainly bends a thin-shaped steel plate into an open C-shaped cross section (as shown in Fig. 1). The cross section includes a large A side A. Two corresponding B sides B parallel to each other and two C sides C respectively parallel to the A side A, wherein both C sides C and C are parallel to maintain an opening distance D, thereby forming an opening of a C-shaped steel I surface.

In the early years, C-shaped steel I, whether it was a beam of a solar panel bracket or a longitudinal beam (not shown), can only be assembled by the A-side A and B-side B of the C-shaped steel I. The side A can be used as the main force surface. The main reason is that the B side B as the main force surface will cause the one side A side A to be severely deformed and cause deformation, but the A side A as the main force surface will be subject to many processing. And assembly restrictions.

Based on the above, in recent years, the industry has developed a jig-type fixing structure using the C side C as a force receiving surface and a combined interface. Among them, the Taiwan Patent Application No. 105216474 "straight-laid slider fixing component" is more representative. (referred to as citation 1) and Taiwan Patent Application No. 105211397 "Beam Docking Device" (referred to as Citation 2) are all using the C side C and C of C-shaped steel I as the combined interface, so that the two C sides C and C are the main The force-receiving surface (as shown in Fig. 1), the above two cases use an outer cover 40 (corresponding to the plate body 11 of the cited 1 and the main fixing plate 1 of the citation 2) which is externally covered by the C-shaped steel I. And an inner seat 50 which can be locked from the inside of the C-shaped steel I to the outer cover 40 (corresponding to the lock of the reference 1 and the reference 2) The piece 20) forms a fixed structure (referred to as a clamp structure) similar to the inner side of the C side C (as shown in Fig. 1), although the design of the cover 40 is slightly different in each design, but the same manner is adopted. Clamping structure.

The above-mentioned fixture structure has found many defects after long-term use:

1. The contact area between the inner seat 50 and the C-shaped steel I is insufficient, and the overall clamp structure is very weak against the lateral force: the inner seat 50 (equivalent to the lock 20) and the outer cover 40 can be known from FIG. The equivalent plate body 11) is mainly locked by screws, and the lateral force (horizontal tension) is very weak. The reason is that the inner seat 50 (equivalent to the lock 20 of the reference 1) and the C-shaped steel I are only on both sides thereof. The thickness of the bent plate body is in contact with the C sides C and C to generate frictional force, and is too weak to avoid lateral sliding (refer to FIG. 5 of the cited drawing 1), even if the inner seat 50 and the outer cover 40 have a locking strength. Stronger, it is not effective against lateral forces and is therefore prone to lateral slippage, especially in strong crosswind environments where the traditional inner seat 50 is often unable to withstand the strong lateral forces generated by strong crosswinds.

2. The assembly steps of the inner seat 50 and the outer cover 40 are complicated and cannot be pre-assembled in the C-shaped steel I, and the inner seat 50 is easy to cause skew or offset during the assembly process: it can be known from the above-mentioned fixture structure that the inner seat 50 And the outer cover 40 can not be pre-assembled on the C-shaped steel I at the factory end, but must be assembled on site, and the appropriate size screws, washers (gaskets) and other components are placed on the site, resulting in assembly time is often too cumbersome, and thus A large amount of assembly time is required, especially the adjustment and positioning of the inner seat 50 is not easy and time consuming, and if a few parts are missing or insufficient in the assembly process, the engineering delay may be seriously caused.

In order to achieve the above objects and effects, the technical means and the structure of the present invention are described in detail in the preferred embodiments of the present invention. The features and functions of the present invention are as follows: The pre-assembled elastic inner seat of the present invention is The lock can be used as a fixture structure or as a separate use with the conventional clamp cover 40, and is not limited in the present invention. When the elastic inner seat 1 and the clamp outer cover 40 of the present invention are locked as a clamp structure, the strength can be resisted. In addition to the lateral force (horizontal force), the elastic inner seat 1 and the clamp outer cover 40 of the present invention are used for locking the locking member S. In the present invention, the carriage screw S1 or the outer hexagon screw is preferably used, but the present invention This is not limited to this, which is described first.

Referring to Figures 2 to 5, the present invention provides a pre-assembled elastic inner seat that combines rapid assembly and high strength for use with a clamp outer cover 40 as a pre-assembled clamp structure (as shown in Figure 5). The elastic inner seat 1 includes at least one bottom plate 10, at least two elastic wing portions 20, and at least two vertical plates 30; wherein the elastic wing portions 20, 20 are disposed on opposite sides of the bottom plate 10, and the vertical plate 30 is It is disposed on the adjacent side of the two elastic wing portions 20 (as shown in FIG. 3). In more detail, the bottom plate 10 is a rectangular sheet shape having a long and short side, and the short side of the bottom plate is slightly smaller than C. The opening distance D of the steel plate I, and the long side of the bottom plate 10 is slightly smaller than the A side A of the C-shaped steel I, and a single or a plurality of positioning holes 101 are provided at the center of the bottom plate 10. In the embodiment, the positioning hole 101 has the most shape. Preferably, the rectangular positioning hole 101 or the plurality of bumps 102 are added around the positioning hole 101, and the bumps are disposed along the circumference of the nut S11 (as shown in FIG. 3) to ensure the nut S11 and the present The inner seat 1 of the invention rotates synchronously. When the positioning hole 101 is set as the rectangular positioning hole 101, the horse-mounted screw S1 is used as the pair of the clamp outer cover 40. The locking element S is preferred (as shown in Fig. 6), and the carriage screw S1 is used because the nut S11 of the carriage screw S1 and the bolt S12 have a rectangular embedded block S13, and the embedded block is used. The S13 is embedded in the positioning hole 101 of the bottom plate 10 (as shown in FIG. 6), so that the assembler can control the elastic inner seat 1 to rotate synchronously inside the C-shaped steel I by the carriage screw S1 bolt end S12 to generate a positioning effect (such as the seventh). Figure shows).

Referring to FIG. 4, each of the elastic wing portions 20 is disposed on two corresponding sides (left, right or front and rear sides) of the short side of the bottom plate 10, and each of the elastic wing portions 20 faces the bottom plate at a first angle θ1 The first direction of the elastic wing portion 20 and the bottom plate 10 is a first elastic force f1. Generally, the first angle θ1 formed between the elastic wing portion 20 and the bottom plate 10 is not greater than 90 degrees. Preferably, the middle portion of each elastic wing portion 20 is bent by a second angle θ2, so that the elastic wing portion 20 can be divided into the upper half wing portion 21 and the lower half wing portion 22 and simultaneously have a second elastic force f2. It is preferable that the second angle θ2 is between 15 degrees and 80 degrees.

Each vertical plate 30 is disposed on an adjacent side (front, rear side or left and right sides) of the two elastic wing portions 20, and extends vertically upward from the long side of the bottom plate 10 to limit the elastic wing portion. The deformation angle of 20 is the maximum, and the height is not higher than the upper half wing portion 21. Generally, the height is preferably between the bottom plate 10 and the upper half wing portion 21, and one end of the vertical plate 30 is provided. There is an outer end edge 31, and the outer end edge 31 is aligned with the opposite outer side of the rotation bevel 212. The other end of the vertical plate 30 is provided with an inner end edge 32, and the inner end edge 32 is aligned with the rotation. The opposite inner side of the beveled corner 212, and the inner end edge 32 allows the bottom plate 10 to be directly placed inside the C-shaped steel I and rotated to complete the positioning, and the upper half wing portion 21 and the vertical plate 30 At the same time, it is pressed against the side of the C-shaped steel I.

Through the above structure, the elastic inner seat 1 of the present invention can easily achieve the advantages that the conventional jig structure is far from being able to achieve:

1. The elastic inner seat 1 and the clamp outer cover 40 of the present invention can adopt a pre-assembled design, which greatly reduces the assembly steps and assembly time: the elastic inner seat 1 and the clamp outer cover 40 of the present invention can be first used outside the C-shaped steel I, using a carriage The screw S1 assembles the two (the elastic inner seat 1 and the clamp outer cover 40) into one body (as shown in Fig. 7). The elastic inner seat 1 has a short short side, and the elastic inner seat 1 is embedded in the C by a C-shaped steel I opening. Profile steel I inside, without C type The front and rear ends of the steel I are inserted so that the elastic inner seat 1 is located inside the C-shaped steel I, and the clamp outer cover 40 is located outside the C-shaped steel I (as shown in Figs. 8 to 10). The assembler is driven by the carriage screw S1. The bolt S12 can control the synchronous rotation of the elastic inner seat 1 inside the C-shaped steel I (as shown in Figs. 10 to 11) so that the elastic base 1 is rotated 90 degrees inside the C-shaped steel I (as shown in Fig. 12). The elastic base 1 is synchronously positioned (as shown in Fig. 13) and the assembler only needs to directly lock the carriage screw S1 to complete the quick assembly function (as shown in Fig. 10).

Referring to FIG. 11 again, a corner of the edge of the free end 211 of each upper half wing portion 21 of the present invention is provided with a rotation angle 212 (as shown in FIG. 11) to avoid the elastic inner seat 1 in the C-shaped steel. When I rotates internally, the corners of the C-shaped steel I interfere with each other and cannot rotate. In the case of the elastic inner seat 1, the rotation angles 212 of the upper half-wings 21 must be staggered (as shown in Fig. 11). The elastic inner seat 1 is rotated clockwise or counterclockwise in the C-shaped steel I, and the other rim corner is used as the stop positioning portion 213 (as shown in Fig. 12).

2. The anti-lateral force strength and the vertical tensile strength of the present invention are much higher than the conventional jig: as shown in Fig. 14, the elastic wing portion 20 provided in the elastic inner seat 1 of the present invention can be used to make the elastic inner seat 1 of the present invention The first elastic force f1 and the second elastic force f2 are provided, and the contact area between the elastic base 1 and the C-shaped steel I of the present invention can be effectively increased (as shown in FIG. 15); when the elastic inner seat 1 and the clamp of the present invention The outer cover 40 is urged by the carriage screw S1 (as shown in Fig. 15). The first angle θ1 between the elastic wing portion 20 and the base 1 and the second angle θ2 between the upper half wing portion 21 and the lower half wing portion 22 At the same time, the angle between the base 1 and the C-shaped steel I is changed by the lock pressure. When the vertical plate 30 is pressed against the C side C of the C-shaped steel I, the change is stopped (as shown in Fig. 15), so that the upper portion The contact area of the half wing portion 21 and the C side surface C is larger. At the same time, the first elastic force f1 and the second elastic force f2 facilitate the tension between the bottom plate 10 and the C side surface C of the C-shaped steel I, so that the upper half wing The portion 21 is more tightly integrated with the C side C. In terms of structure, the elastic inner seat 1 of the present invention can resist the lateral force (horizontal force) much larger than the conventional conventional clip. With structure, there is no doubt.

As shown in Fig. 16, when the elastic inner seat 1 of the present invention is subjected to a vertical pulling force, the vertical plate 30 is resisted, and when the pulling force is too large, the bottom plate 10 is pulled up by the carriage screw S1 (the locking member S) until it is deformed. The first angle θ1 and the second angle θ2 of the elastic wing portions 20 on the two corresponding sides of the bottom plate 10 are subjected to greater pressure between the base 1 and the C-shaped steel I, except that the upper half wing portion 21 is in contact with the C side surface C. In addition to the larger area, it will also expand outwardly to more closely support the internal space of the C-shaped steel I, making it difficult for the elastic base 1 of the present invention to be pulled away from the C-shaped steel I.
