The connecting frame includes a bottom plate, two adjacent transverse side plates and a longitudinal side plate vertically arranged on the bottom plate. A long strip-shaped guiding hole is arranged on the bottom plate along the transverse direction. An insertion port is arranged at a position close to the longitudinal side plate of the long strip-shaped guiding hole, and the size of the insertion port is larger than the width of the long strip-shaped guiding hole. A positioning block is arranged at a position close to the longitudinal side plate on the bottom surface of the bottom plate. The positioning block has a T-shaped cross-section. The positioning block on one connecting frame is inserted into the insertion port of the adjacent connecting frame from top to bottom and slides along the long strip-shaped guiding hole for positioning to adjust the distance between the two connecting frames.

[0005] Preferably, clamping grooves are arranged at the top surfaces of the left and right ends of the transverse side plates. After two adjacent connecting frames are pulled apart in place, the two transverse side plates are fixed by clamping blocks being clamped into the two clamping grooves.

[0006] Preferably, the number of the connecting frames is at least three. The bottoms of two adjacent connecting frames are sequentially connected and positioned through the positioning block and the long strip-shaped guiding hole, and the tops are connected and positioned through the clamping block and the clamping groove. And the height of the bottom plate of the connecting frame at the upper part is increased in sequence to ensure that the bottom surfaces of all the connecting frames are at the same height.

[0007] Preferably, a fixing bracket is provided on one side of the connecting bracket with the highest bottom plate height. A positioning block is provided at the bottom of the fixing bracket and is slidably connected by being inserted into the long strip-shaped guiding hole of the adjacent connecting bracket. A clamping groove is provided on the top surface at the rear side of the fixing bracket, and the connection between the top of the connecting bracket and the fixing bracket is achieved by clamping a clamping block into the clamping groove of the connecting bracket.

Detailed Embodiment

[0020] The present utility model will be further described in detail below with reference to the drawings.

[0021] As Figures 1 to 8 shown, the present utility model provides a telescopic desktop bookshelf, which includes at least two connecting frames 1. The connecting frame 1 includes a bottom plate 11, two adjacent transverse side plates 12 and a longitudinal side plate 13 vertically arranged on the bottom plate 11. A long strip-shaped guiding hole 111 is arranged horizontally on the bottom plate 11. An insertion port 112 is arranged near the longitudinal side plate 13 of the long strip-shaped guiding hole 111. The size of the insertion port 112 is larger than the width of the long strip-shaped guiding hole 111. A bevel or a smooth curved surface is provided for transition between the insertion port 112 and the long strip-shaped guiding hole 111. A positioning block 113 is arranged at the bottom surface of the bottom plate 11 near the longitudinal side plate 13. The positioning block 113 has a T-shaped cross-section. The positioning block 113 on one connecting frame 1 is clamped into the insertion port 112 of the adjacent connecting frame 1 from top to bottom and slides along the long strip-shaped guiding hole 111 for positioning to adjust the distance between the two connecting frames 1.

[0022] Wherein, the number of the long strip-shaped guiding holes 111 is two, which are distributed in parallel, and the corresponding number of the positioning blocks 113 is also two.

[0023] In the above solution, clamping grooves 121 are arranged at the top surfaces of the left and right ends of the transverse side plate 12. After two adjacent connecting frames 1 are pulled to the place in place, the two transverse side plates 12 are fixed by clamping blocks 2 clamped into the two clamping grooves 121.

[0024] In addition, the number of the connecting frames 1 is at least three. The bottoms of two adjacent connecting frames 1 are sequentially connected and positioned through the positioning block 113 and the long strip-shaped guiding hole 111, and the tops are connected and positioned through the clamping block 2 and the clamping groove 121. The height of the bottom plate 11 of the connecting frame 1 above is increased in turn to ensure that the bottom surfaces of all the connecting frames 1 are at the same height.

[0025] In addition, a fixing frame 3 is arranged on one side of the connecting frame 1 with the highest bottom plate 11. A positioning block 113 is arranged at the bottom of the fixing frame 3 and is clamped into the long strip-shaped guiding hole 111 of the adjacent connecting frame 1 for sliding connection. A clamping groove 121 is arranged at the top surface of the rear side of the fixing frame 3, and the top of the connecting frame 1 and the fixing frame 3 are connected by clamping the clamping block 2 into the clamping groove 121 of the connecting frame 1; A drawer 4 is arranged in the fixing frame 3.

[0026] Specifically, two rows of drawers 4 are arranged up and down in the fixing frame 3.

[0027] Furthermore, a gripping hole 131 is arranged at the top of the longitudinal side plate 13 of the connecting frame 1 with the lowest bottom plate 11.

[0028] The utility model connects and positions multiple connecting frames 1 through positioning blocks 113 and long-strip-shaped guide holes 111, enabling the multiple connecting frames 1 to be expanded or contracted to change the shape, so that it can be matched with different desktops, with diverse usage methods, novel structure. With the structure of the fixing frame 3 and the design of the drawer 4, the needs of more users are met. During assembly, only need to snap the positioning block 113 on the upper connecting frame 1 into the insertion port 112 of the lower connecting frame 1 from top to bottom and slide along the long-strip-shaped guide hole 111 to achieve the connection of the two, and the distance between the two connecting frames 1 is positioned and adjusted by the sliding distance.

[0029] The above is only the preferred embodiment of the utility model and does not impose any formal limitations on the utility model. Any simple modification, equivalent change or decoration made to the above embodiments based on the technical principle of the utility model still falls within the scope of the technical solution of the utility model.
