On the basis of the above solution and as a preferred solution of the above solution, the socket head and the sleeve are connected by screw threads, and the end of the sleeve is recessed with a driving groove for rotational fixation.

On the basis of the above solution and as a preferred solution of the above solution, a limit block is protruded on the end of the pin shaft to prevent the pin shaft from popping out of the sleeve, and the end of the spring is connected with the limit block.

Compared with the prior art, the beneficial effect of the present invention is that the telescopic connectors are evenly arranged on the fixing frame, and the mounting frame is pushed to push the pins in the connectors into the sleeve heads, so that the pins are connected to the bottom of the mounting block. Connection, the mounting frame is supported and fixed by the pin, the fixed frame and the mounting frame do not need to be drilled and positioned, and the overall disassembly and assembly is very convenient, which is conducive to the replacement of parts and reduces the difficulty of maintenance.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIG. 1 to FIG. 2 , the present invention provides a technical solution: a telescopic connecting light frame, comprising a fixing frame 1 , a mounting frame 2 and a connecting piece 3 , and a plurality of connecting pieces 3 are evenly distributed on the fixing frame 1 , the connector 3 includes a sleeve 31 , a sleeve 32 , a pin 33 and a spring 34 .

The sleeve head 31 passes through the fixing plate 11 at the lower end of the fixing frame 1 , the sleeve 32 is arranged inside the fixing plate 11 and sleeved on the sleeve head 31 , the sleeve head 31 and the sleeve 32 are connected by threads, and the end of the sleeve 32 is There is a drive slot 321 for rotating and fixing. Inserting a screwdriver into the drive slot 321 can rotate the sleeve 32, so that the sleeve head 31 and the sleeve 32 are fixed on the fixing plate 11. The disassembly is simple, and the parts can be replaced and repaired at any time when damaged. low cost. The pin shaft 33 is passed through the sleeve head 31 , one end of the pin shaft 33 is set in the sleeve head 31 and a spring 34 is sleeved, and the end of the pin shaft 33 close to the sleeve head 31 is protruded with a limit to prevent the pin shaft 33 from popping out of the sleeve head 31 .
