DETAILED DESCRIPTION

[0020] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0021] like Figure 1-Figure 4 As shown, the present embodiment provides a direct-reading spectrometer which is easy to repair, including a direct-reading spectrometer body 1, a spark stand 2 located at the top of the direct-reading spectrometer body 1, and a table 3 installed on the spark stand 2, the outer sides of the inside of the table 3 are provided with mutually conductive limit grooves 4, the ends of the limit grooves 4 are rotatably installed with gears 5, the outer sides of the gears 5 are meshed with toothed belts 6, the tops of the gears 5 are provided with cross grooves 7, and the tops of the gears 5 are flush with the tops of the table 3, the bottoms of the gears 5 are fixed with through pipes 8, the through pipes 8 penetrate the table 3 and are rotatably connected with the table 3, the insides of the gears 5 are provided with screws 9 for vertical sliding, and the screws 9 penetrate the through pipes 8, the inner bottoms of the gears 5 are provided with sliding holes 10 cooperating with the screws 9, and the insides of the sliding holes 10 are provided with a limiting mechanism for limiting the vertical sliding of the screws 9.

[0022] General working principle: When disassembling the table 3, insert a cross screwdriver into the cross slot 7 to control a group of gears 5 to rotate. Since the gears 5 are connected by toothed belts 6, multiple groups of gears 5 rotate at the same time. The rotation of the gears 5 will drive the screw 9 to rotate at the same time. The screw 9 moves upward and separates from the inside of the installation slot. Then the table 3 is removed and the spark stand 2 is inspected.

[0023] In this embodiment, the table top 3 includes an upper cover 14, a bottom plate 15 and fixing screws 16, the limiting groove 4 is opened on the outer side of the top of the bottom plate 15, the upper cover 14 covers the top of the bottom plate 15, and fixing screws 16 are installed between the upper cover 14 and the bottom plate 15.

[0024] Partial working principle: the table top 3 is a whole composed of an upper cover 14, a bottom plate 15 and fixing screws 16, which can better install and fix the components inside the table top 3.

[0025] In this embodiment, a protrusion is provided on the top of the gear 5 , and the protrusion passes through the upper cover 14 , and the cross groove 7 is located on the top of the protrusion.

[0026] Partial working principle: The top of the gear 5 is flush with the top of the upper cover 14 to avoid the protrusion of the gear 5 from hindering the placement of the detection parts and ensure the flatness of the top of the platform 3.

[0027] In this embodiment, the limiting mechanism includes a guide groove 12 and a guide block 13. Guide grooves 12 are vertically opened on both sides of the sliding hole 10. The two groups of guide grooves 12 are symmetrical to each other. Guide blocks 13 are vertically slidably provided inside the guide grooves 12, and the guide blocks 13 are fixed on the top of the screw rod 9.

[0028] Local working principle: When the screw 9 rotates simultaneously with the gear 5, the screw 9 is limited by the guide block 13 and the guide groove 12, so the screw 9 can only move vertically upward inside the slide hole 10 and cannot rotate relative to the slide hole 10, ensuring that the screw 9 can be quickly disassembled and installed.

[0029] In this embodiment, a spring 11 is installed between the inner top of the sliding hole 10 and the top of the screw rod 9 , and the initial length of the spring 11 is greater than the height of the gear 5 .

[0030] Local working principle: When the screw rod 9 rises, it will squeeze the spring 11. After the screw rod 9 is separated from the inside of the mounting hole, the cross screwdriver is removed. At this time, the table plate 3 loses the downward pressure, and the spring 11 returns to its original position to lift the table plate 3 so that the table plate 3 can be removed.

[0031] In this embodiment, the outer side of the bottom of the bottom plate 15 is provided with an inclined surface, and the inclined surface is provided with a wear-resistant coating.

[0032] Partial working principle: The setting of the outer inclined surface of the bottom plate 15 can facilitate the guidance when the table plate 3 is installed, and facilitate the alignment of the table plate 3 with the installation position.

[0033] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
