[0026] The utility model will be described in detail below in combination with the drawings. As shown in the drawings. Figures 1 to 5 As shown in the drawings.

[0027] Embodiment 1: a hardware connector, comprising two L-shaped connecting pieces 2, the connecting piece 2 includes a vertical section 22 and a horizontal section 21, the two sides of the vertical section 22 are respectively provided with a laterally arranged T-shaped groove 221, the T-shaped groove 221 includes a horizontal groove 2211 in communication with the outside and a vertical groove 2212 located on one side of the horizontal groove 2211, two connecting clamping columns 1 are connected between the two connecting pieces 2, the connecting clamping column 1 includes a connecting part located in the middle and a limiting part located on both sides, the two ends of the connecting part are respectively inserted into the corresponding T-shaped groove 221, and the limiting part is located on the outside close to the connecting piece 2 and abuts against the connecting piece 2.

[0028] When the present technology is connected to two spaced objects, the horizontal section 21 of the two connecting pieces 2 is fixed on the surface of the two objects respectively, and the vertical section 22 of the two connecting pieces 2 is arranged oppositely; then the connecting clamping column 1 enters the horizontal groove 2211 of the corresponding two T-shaped grooves 221 from one side of the two connecting pieces 2, and then enters the bottom of the vertical groove 2212 of the T-shaped groove 221. The limiting parts at both ends of the connecting clamping column 1 abut against the corresponding connecting pieces 2.

[0029] The structure of the connecting piece 2 is relatively simple compared with the structure of the main connecting plate and the auxiliary connecting plate of the background technology, the vertical section 22 of the two connecting pieces 2 is connected by clamping connection through the connecting clamping column 1, and in the use process, the up-down width of the horizontal groove 2211 is equal to or slightly larger than the thickness of the clamping connection column, for example, 1mm larger; so that the clamping connection column can smoothly enter the vertical groove 2212, but it is not easy to enter the horizontal groove 2211 from the vertical groove 2212, so that the overall structure is relatively stable, and the clamping connection column is not easy to separate from the vertical groove 2212.

[0030] Secondly, it needs to be explained that, considering the strength of the vertical section 22, the thickness of the vertical section 22 can be appropriately thick, such as above 5mm. If necessary, a reinforcing rib is provided between the vertical section 22 and the horizontal section 21 to improve the structural strength of the vertical section 22.

[0031] Referring to Figure 2 , the horizontal section 21 is provided with a plurality of connecting holes 213. Preferably, the middle part of the horizontal section 21 is provided with a horizontal connecting groove 212.

[0032] In order to facilitate the connection of the connecting sheet 2 with the object, the horizontal section 21 is provided with a plurality of connecting holes 213 in the embodiment; secondly, in order to facilitate the adjustment of the connecting position of the horizontal section 21 and the distance between the vertical sections 22 of the two connecting sheets 2, the horizontal section 21 is provided with a horizontal connecting groove 212 in the embodiment, and more preferably, the upper end of the horizontal connecting groove 212 is provided with a counterbore 211; when connected with a bolt or a screw, the head part is located in the counterbore 211, avoiding protrusion.

[0033] Referring to Figure 3 , the connecting clamping column 1 is of a telescopic structure, which comprises a main sleeve 11 and a secondary sleeve 12, the main sleeve 11 is sleeved with the secondary sleeve 12, and one end of the main sleeve 11 and the secondary sleeve 12 is respectively connected with a limiting disc 13.

[0034] The connecting clamping column 1 is provided as a telescopic structure, so that the use length of the connecting clamping column 1 can be adjusted, and the connecting clamping column 1 can be quickly clamped with the T-shaped groove 221. The limiting disc 13 is the limiting part.

[0035] Referring to Figure 4 , the main sleeve 11 is provided with a spring 17, one end of the spring 17 is connected with the adjacent limiting disc 13, and the other end of the spring 17 is connected with the other limiting disc 13 through the secondary sleeve 12.

[0036] The spring 17 is arranged in the main sleeve 11 and the secondary sleeve 12, and the two limiting discs 13 are connected through the spring 17; the separation of the main sleeve 11 and the secondary sleeve 12 can be avoided, and the main sleeve 11 and the secondary sleeve 12 are always in the sleeved state; at the same time, it is also convenient to adjust the length of the whole connecting clamping column 1.

[0037] Referring to Figure 3 , Figure 4 , the root of the secondary sleeve 12 is provided with an external thread, the front end of the main sleeve 11 is provided with an internal thread, and the secondary sleeve 12 is threadedly connected with the main sleeve 11.

[0038] When two connecting pieces 2 are connected by connecting card column 1, if the separation of main sleeve 11 and secondary sleeve 12 is prevented by spring 17, the pulling force of spring 17 is relatively high, and it is relatively difficult to control the length of connecting card column 1 artificially. In order to facilitate operation, the root of secondary sleeve 12 and the front end of main sleeve 11 are provided with threads in the embodiment; when not in use, secondary sleeve 12 and main sleeve 11 are connected by sleeving, not threaded connection, and spring 17 connects secondary sleeve 12 and main sleeve 11 into one; when in use, connecting card column 1 is clamped into T-shaped slot 221 from the side; at this time, the distance between the limiting parts at both ends and the vertical section 22 of connecting piece 2 has a gap, and then main sleeve 11 or / and secondary sleeve 12 is rotated.

[0039] When the distance between two connecting pieces 2 is relatively short, main sleeve 11 and secondary sleeve 12 are connected by threaded connection; when the distance between two connecting pieces 2 is relatively long, main sleeve 11 and secondary sleeve 12 are connected by sleeving, which can quickly adjust the relative position, and at this time spring 17 can provide sufficient pulling force.

[0040] Referring to Figure 3 , Figure 4 , one side of limiting disc 13 is provided with connecting ring 14, main sleeve 11 is connected with corresponding connecting ring 14 in interference fit, and secondary sleeve 12 is connected with corresponding connecting ring 14 in interference fit.

[0044] When the main sleeve 11 is connected with the secondary sleeve 12 by screwing, the main sleeve 11 rotates relative to the secondary sleeve 12, at this time, the internal spring 17 can also rotate, thereby affecting the structure of the spring 17; in order to avoid this situation, the embodiment is provided with a round sheet 15 in the connecting ring 14, the round sheet 15 can rotate relative to the connecting ring 14; when the main sleeve 11 or the secondary sleeve 12 rotates relative to each other, the round sheet 15 at the end will rotate relative to each other, so as to keep the spring 17 from rotating. When the round sheet 15 is connected with the connecting ring 14, it can also be installed by the way of thermal expansion and cold contraction, the outer diameter of the annular groove is greater than or equal to the diameter of the round sheet 15.

[0045] The above merely describes the preferred embodiments of the present application, and for those skilled in the art, the specific implementation manners and application scopes can be changed according to the thought of the present application, and the content of the specification should not be understood as the limitation of the present application.
