Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and fig. 3, the quick-change fastening structure includes two support plates 1, the two support plates 1 are U-shaped and are opposite to each other, and guide grooves 11 are respectively formed on opposite sides of the two support plates 1. The top surfaces of the two support plates 1 are respectively provided with a plurality of through holes 12 penetrating through the guide grooves 11, spring studs 13 are nested in the through holes 12, the bottoms of the spring studs 13 are provided with balls 14, and the balls 14 are rotatably connected with the spring studs 13, so that the balls 14 can roll relative to the bottom surfaces of the spring studs 13 when thrust is applied to the balls 14. The two support plates 1 are provided with a limiting baffle 15 at one end close to the through hole 12, the limiting baffle 15 has a blocking effect on one side of the guide groove 11, and one end of any plate cannot penetrate through the guide groove 11 in the process of embedding the plate into the guide groove 11. Mounting holes 16 are formed in the top surfaces of the other ends of the two support plates 1, limiting bolts 17 are mounted in the mounting holes 16, the limiting bolts 17 are opposite to and matched with through holes 18 formed in the bottom surfaces of the support plates 1, the through holes 18 are opposite to the mounting holes 16, the limiting bolts 17 are screwed after the limiting bolts 17 penetrate through the mounting holes 16 from top to bottom, and the bottom surfaces of the limiting bolts 17 can be embedded and fixed in the through holes 18; after the plate is inserted into the guide groove 11, the limit bolt 17 is fixed to the through hole 18, so that the limit bolt 17 and the limit baffle 15 limit the plate.
As shown in fig. 1 and 2, a housing 2 is disposed between two support plates 1, and any module can be mounted on the top surface of the housing 2, such as: the system comprises a smoke exhaust module, a water cannon module and a detection module on the fire-fighting robot. The connecting plates 21 arranged on two sides of the bottom of the shell 2 are respectively embedded into the guide grooves 11 on the two support plates 1, the connecting plates 21 on two sides of the bottom of the shell 2 are respectively provided with a plurality of grooves 22, the grooves 22 are nested with the balls 14 on the support plates 1, when the shell 2 is arranged between the two support plates 1, the two connecting plates 21 on the shell 2 are respectively embedded into the guide grooves 11 on the two support plates 1, the spring studs 13 are extruded and contracted upwards in the process that the connecting plates 21 are embedded into the guide grooves 11, when the back surfaces of the connecting plates 21 are attached to the limiting baffle plates 15, the grooves 22 on the connecting plates 21 are opposite to the balls 14 on the spring studs 13, the spring studs 13 are not extruded and reset downwards, the balls 14 on the spring studs 13 are embedded into the grooves 22, and therefore the connecting plates 21 are fixed after being embedded into the guide grooves 11.
