The first embodiment is as follows:

referring to fig. 1, in the present embodiment, a rail connecting structure for a metal drawer includes a metal side plate 1 and a drawer rail (substantially, a drawer rail including an upper rail 2), wherein, the metal side plate 11 of the present embodiment is made of a thin plate structure made of a metal material, such as the drawer structure in the patent CN209152693U filed by the present applicant, a bottom connecting block 11 is formed at a bottom end of the metal side plate 11 by inward folding for carrying a drawer bottom plate 44. In addition, the drawer rail of this embodiment may be an existing "two-section rail" or "three-section rail" structure, refer to patent CN2016305196437, and the present application does not limit a specific drawer rail structure, and those skilled in the art can select a corresponding derived drawer rail according to actual needs, and the present application is not limited herein.

In this embodiment, first, the tail end of the upper slide rail 2 is formed with a hook which is in fastening fit with a fastening groove pre-opened at the tail of the drawer bottom plate 4, and the tail end of the upper slide rail 2 is hung on the drawer bottom plate 4 by the cooperation of the hook and the fastening groove. Secondly, a supporting member 21 protruding from the inner side surface of the upper slide rail 2 and extending to the position below the bottom connecting block 11 is fixedly arranged on the side wall of the upper slide rail 2, and a vertical adjusting bolt 22 is arranged on the supporting member 21, wherein the top end of the vertical adjusting bolt 22 of the embodiment is a circular truncated cone type flat head structure, the middle part thereof is an external thread structure (the external thread is provided with an adjusting nut corresponding to the external thread), and the bottom end thereof is a cylindrical structure (the bottom end is in through fit with a pre-opened hole position on the supporting member 21).

In this embodiment, the vertical adjusting bolt 22 is used to directly cooperate with the bottom connecting block 11, an adjusting portion 12 is formed on the bottom connecting block 11, and the adjusting portion 12 is provided with an adjusting hole which extends vertically and is in threaded fit with the vertical adjusting bolt 22, that is, the adjusting hole is formed with an inner thread which is in threaded fit with an outer thread on the middle portion of the vertical adjusting bolt 22, so that the vertical adjusting bolt 22 is lifted relative to the adjusting hole by manually screwing the adjusting nut, and the adjustment of the vertical distance between the supporting member 21 and the bottom connecting block 11 is realized, that is, when the vertical adjusting bolt 22 moves upwards relative to the adjusting hole, the vertical distance between the supporting member 21 and the bottom connecting block 11 is reduced; on the contrary, when the vertical adjusting bolt 22 moves downwards relative to the adjusting hole, the vertical distance between the supporting member 21 and the bottom connecting block 11 is increased; the operation is simple and convenient, and fine adjustment can be performed according to actual conditions so as to adapt to different installation conditions.

Example two:

referring to fig. 2, the difference between the second embodiment and the first embodiment is that: the vertical adjusting bolt 22 is used for indirectly matching with the bottom connecting block 11, and further comprises a connecting piece 3 arranged between the bottom connecting block 11 and the supporting piece 21, wherein firstly, two convex positioning salient points are formed on the top surface of the connecting piece 3, and two positioning holes 14 for the two positioning salient points to be embedded and assembled are formed in the bottom surface of the bottom connecting block 11 respectively, specifically, the two positioning salient points are a first positioning salient point 31 and a second positioning salient point 32 respectively, wherein the first positioning salient point 31 is located in the middle position of the top surface of the connecting piece 3, the second positioning salient point 32 is located at the front end position of the top surface of the connecting piece 3, and the plane position between the connecting piece 3 and the bottom connecting block 11 is positioned by utilizing a two-point positioning mode. Secondly, two counter bores 33 extending from bottom to top are formed in the bottom surface of the connecting piece 3, first through holes 13 aligned with the counter bores 33 are formed in the bottom connecting block 11, specifically, after fixing screws sequentially penetrate through the counter bores 33 and the first through holes 13 from bottom to top, the front ends of the fixing screws are embedded into the drawer bottom plate 4 borne by the bottom connecting block 11, and therefore the fixed connection among the connecting piece 3, the metal side plate 1 and the drawer bottom plate 4 is achieved.

In the present embodiment, the bottom surface of the connecting member 3 is provided with an adjusting groove 34 for vertically fitting the butt end (top end) of the vertical adjusting bolt 22, specifically, the top end of the vertical adjusting bolt 22 is aligned with the adjusting groove 34 and is fitted into the adjusting groove 34 to realize the contact between the vertical adjusting bolt 22 and the connecting member 3, and the adjusting nut can be screwed manually to lift the vertical adjusting bolt 22 relative to the connecting member 3, so as to adjust the vertical distance between the supporting member 21 and the connecting member 3.

In this embodiment, the bottom surface of the connecting member 3 is provided with at least one lower positioning groove 35 aligned with the second through hole 23 preset on the supporting member 21, wherein two position specifications exist at the position of the second through hole 23 on the supporting member 21 with different specifications, namely, the lower positioning groove 35 is located at the front position of the vertical adjusting bolt 22, and the lower positioning groove 35 is located at the rear position of the vertical adjusting bolt 22, so that the lower positioning groove 35 is provided with two lower positioning grooves arranged in front and rear directions to be suitable for supporting members 21 under different conditions, and it is ensured that at least one lower positioning groove 35 can be aligned and matched with the second through hole 23 on the supporting member 21 in the actual use process. The second through hole 23 and the aligned lower positioning groove 35 are matched with each other by the positioning pin, so that the connection and the matching between the connecting piece 3 and the supporting piece 21 (equivalent to the upper sliding rail 2) are further realized.

In conclusion, the connecting pieces 3 are used for connecting and matching the supporting pieces 21 (equivalent to the upper slide rail 2), the metal side plates 1 and the drawer bottom plate 4, so that the problem that the metal side plates 1 cannot adapt to the existing drawer guide rail is solved, the cost of an enterprise is greatly reduced, and the special drawer guide rail does not need to be additionally researched and developed and produced.

In addition, in order to make the structure of connecting piece 3 more reasonable reliable, the first location bump 31 of this embodiment is vertical with adjustment tank 34 and aligns, second location bump 32 is vertical with arbitrary one lower constant head tank 35 and aligns (the second location bump 32 of this implementation is located the place ahead position of first location bump 31, thereby the second location bump 32 that makes and the lower constant head tank 35 that is located the place ahead position vertical alignment), two constant head tank 35 is symmetrical arrangement in both sides around adjustment tank 34 down, and two counter bores 33 are located respectively between adjustment tank 34 and two lower constant head tanks 35, foretell first location bump 31, second location bump 32, lower constant head tank 35, adjustment tank 34, counter bore 33 all are in same straight line. Therefore, the bumps, the slots and the hole positions on the connecting piece 3 are more compact and reasonable, namely, the bumps, the slots and the hole positions are not mutually influenced, the size of the connecting piece 3 can be smaller, and the cost is lower.

Furthermore, the connecting piece 3 can be made of plastic, and has the advantages of easy production and low cost.
