[0041] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0042] Please refer to Figures 1-6 , the present invention provides a new technical solution: a wire groove telescopic frame, including two bases 1, and a plurality of positioning sliding frames 4 are fixedly connected to the upper surfaces of the two bases 1;

[0043] Among them, a plurality of positioning sliding frames 4 are sequentially sleeved in a sliding manner according to different sizes;

[0046] Further, the telescopic mechanism includes two sliding frames 2, the two sliding frames 2 are in a U shape, and the horizontal plates of the two sliding frames 2 are fixedly connected to the upper surfaces of the two positioning blocks 3;

[0047] Among them, limiting blocks 5 are fixedly connected to the front and rear side surfaces of the vertical plates of the sliding frame 2;

[0048] Among them, a connecting frame 6 is arranged on the two sliding frames 2, and the connecting frame 6 is also in a U shape.

[0049] Further, the connecting frame 6 is slidably sleeved on the outer surfaces of the two sliding frames 2;

[0050] Among them, sliding grooves 7 extending out of the rear side surfaces are opened on the front side surfaces of the two vertical plates of the connecting frame 6;

[0051] Among them, the limiting blocks 5 are slidably connected in the sliding grooves 7.

[0052] Further, threaded holes 8 extending into the inside are opened on the outer surfaces of the positioning sliding frames 4;

[0053] Among them, fixing bolts 9 are threadedly connected in the threaded holes 8, and the fixing bolts 9 extend into the positioning sliding frames 4 through the threaded holes 8.

[0054] Further, two chutes 12 extending out of the upper surface are opened on the lower surface of the horizontal plate of the connecting frame 6;

[0055] Among them, positioning rods 13 are slidably connected in the chutes 12;

[0056] Among them, a plurality of positioning holes 16 extending out of its lower surface are formed on the upper surface of the horizontal plate of the sliding frame 2.

[0057] Further, the lower end of the positioning rod 13 extends out of the lower surface of the horizontal plate of the connecting frame 6 through the sliding groove 12;

[0058] Among them, the upper end of the positioning rod 13 slides into the positioning hole 16 through the sliding groove 12;

[0059] Among them, a fixing plate 15 is fixedly connected to the lower end of the positioning rod 13;

[0060] Among them, an installation spring 14 is fixedly connected between the upper surface of the fixing plate 15 and the lower surface of the horizontal plate of the connecting frame 6, and the installation spring 14 is sleeved on the outer surface of the positioning rod 13.

[0061] Further, a plurality of installation blocks 10 are fixedly connected to the opposite side surfaces of the two vertical plates of the sliding frame 2, and the number of the plurality of installation blocks 10 is determined according to the actual situation;

[0062] Among them, a plurality of installation holes 11 extending out of its lower surface are formed on the upper surface of the installation block 10, and the number of the plurality of installation holes 11 is twice the number of the plurality of installation blocks 10.

[0063] Further, by pulling the positioning sliding frame 4 and the positioning block 3, the integrated telescopic frame can be driven to move up and down, and then the height of the telescopic frame can be adjusted in multiple stages, so that the telescopic frame can be suitable for adjustments of different heights, thereby increasing the practicability and applicability of the device.

[0064] Further, when the fixing bolt 9 is tightened, the fixing bolt 9 will squeeze the outer surfaces of the positioning sliding frame 4 and the positioning block 3, thereby fixing and positioning the positioning sliding frame 4 and the positioning block 3, and then fixing the height of the telescopic frame, thereby ensuring the stability.

[0065] Further, the limiting block 5 is slidably connected with the sliding groove 7 to limit and connect the sliding frame 2 and the connecting frame 6, so that the connecting frame 6 and the sliding frame 2 can only have relative displacement in the left-right direction, and will not have relative displacement in other directions, and the connecting frame 6 will not be separated from the sliding frame 2, thereby playing a connecting role and ensuring the stability of the telescopic frame.

[0066] Further, in the initial state, the upper end of the positioning rod 13 slides into the positioning hole 16 through the sliding groove 12, and at this time, the positioning rod 13 fixes the positioning sliding frame 4 and the connecting frame 6, so that the positioning sliding frame 4 and the connecting frame 6 cannot slide relative to each other left and right, and then fixes the length of the telescopic frame, thereby ensuring the stability of the telescopic frame.

[0067] Further, when it is necessary to adjust the length of the telescopic frame, the fixed plate 15 needs to be pulled downward. The fixed plate 15 moves upward, and the fixed plate 15 moves downward to stretch the mounting spring 14. Moreover, the downward movement of the fixed plate 15 synchronously drives the positioning rod 13 to move downward. The positioning rod 13 moves downward out of the positioning hole 16. At this time, the positioning rod 13 no longer fixes the positioning sliding frame 4 and the sliding frame 2. At this time, the sliding frame 2 can be pulled to cause relative displacement between the sliding frame 2 and the positioning sliding frame 4. At this time, the length of the telescopic frame can be adjusted, so that the length of the telescopic frame is telescopic. Furthermore, the applicability and practicability of the wire groove telescopic frame are ensured. The adjustment is convenient and fast, saving manpower, so that the wire groove telescopic frame can be applied to the installation of electrical components with different widths.

[0068] Working principle: When the device is in use, by pulling the positioning sliding frame 4 and the positioning block 3, the entire telescopic frame can be driven to move up and down, and the height of the telescopic frame can be adjusted in multiple stages. Thus, the telescopic frame can be adapted to different height adjustments, increasing the practicability and applicability of the device.

[0069] Further, when the fixing bolt 9 is tightened, the fixing bolt 9 will squeeze the outer surfaces of the positioning sliding frame 4 and the positioning block 3, thereby fixing and positioning the positioning sliding frame 4 and the positioning block 3, and then fixing the height of the telescopic frame, thus ensuring stability.

[0070] Further, the limiting block 5 is slidably connected to the sliding groove 7 to limit and connect the sliding frame 2 and the connecting frame 6, so that the connecting frame 6 and the sliding frame 2 can only have relative displacement in the left-right direction and will not have relative displacement in other directions, and the connecting frame 6 will not be separated from the sliding frame 2, thereby playing a connecting role and ensuring the stability of the telescopic frame.

[0071] Further, in the initial state, the upper end of the positioning rod 13 slides through the sliding groove 12 and extends into the positioning hole 16. At this time, the positioning rod 13 fixes the positioning sliding frame 4 and the connecting frame 6, so that the positioning sliding frame 4 and the connecting frame 6 cannot slide relatively left and right, thereby fixing the length of the telescopic frame and ensuring the stability of the telescopic frame.

[0072] Further, when it is necessary to adjust the length of the telescopic frame, the fixing plate 15 needs to be pulled downward. The fixing plate 15 moves upward, and the fixing plate 15 moves downward to stretch the mounting spring 14. And the downward movement of the fixing plate 15 synchronously drives the positioning rod 13 to move downward. The positioning rod 13 moves downward out of the positioning hole 16. Then, at this time, the positioning rod 13 does not fix the positioning sliding frame 4 and the sliding frame 2. Then, at this time, the sliding frame 2 can be pulled so that a relative displacement occurs between the sliding frame 2 and the positioning sliding frame 4. Then, at this time, the length of the telescopic frame can be adjusted, so that the length of the telescopic frame is telescopic, thereby ensuring the applicability and practicability of the wire groove telescopic frame, being convenient and fast to adjust, saving manpower, and enabling the wire groove telescopic frame to be applicable to the installation of electrical components with different widths.
