Detailed Implementation

[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 As shown, Figure 1 A structural view of the magnetron float of the electric tea boiler on a high-speed train.

[0025] The quick-release tooling for the float of the magnetron in the electric tea stove of the EMU described in this utility model is used to disassemble the float support 2 inside the magnetron 1 of the electric tea stove. The magnetron 1 is provided with a float 4, the float support 2 is provided inside the magnetron 1, and a disassembly plug 3 is provided at one end of the float support 2. The disassembly plug 3 is inserted into and fixed to the end of the magnetron 1. The disassembly plug 3 is provided with a disassembly hole 31, and the disassembly hole 31 is coaxially arranged with the magnetron 1.

[0026] like Figure 2 As shown, Figure 2 This is a schematic diagram of the quick-release tool for disassembling the float support of the magnetron float in the electric tea boiler of the high-speed train.

[0027] The quick-release tooling for the magnetron float of the electric tea stove in the high-speed train of this utility model includes a disassembly rod 5 and a handle 6. One end of the disassembly rod 5 is fixedly connected to the handle 6. The disassembly rod 5 is provided with a plurality of friction ridges 7. The cross-sectional diameter of the disassembly rod 5 is smaller than the diameter of the disassembly hole 31, so that the disassembly rod 5 can be inserted into the interior of the disassembly hole 31. The friction ridges 7 generate friction with the inner wall of the disassembly hole 31, thereby pulling the disassembly plug 3 out of the magnetron tube 1.

[0028] Preferably, the friction ridge 7 has a triangular cross-section and is circumferentially wound around the disassembly rod 5. The disassembly plug 3 is generally made of plastic. The tip of the friction ridge 7 scrapes the plastic disassembly plug 3, thereby facilitating the removal of the disassembly plug 3 from the magnetron tube 1.

[0029] Preferably, a disassembly ring 32 is provided inside the disassembly hole 31. The disassembly ring 32 is a circular structure fixed inside the disassembly hole 31. Through the engagement between the friction ridge 7 and the disassembly ring 32, the axial force applied by the disassembly rod 5 to the disassembly plug 3 is increased, which facilitates the removal of the disassembly plug 3 from the magnetron tube 1.

[0030] This invention utilizes a disassembly rod 5 with the friction ridge 7, which is inserted into the disassembly hole 31. The friction between the friction ridge 7 and the inner wall of the disassembly hole 31 is used to disassemble and assemble the float, eliminating the need to disassemble many other accessories. This achieves rapid disassembly and assembly, improves fault handling efficiency, avoids damage to the magnetron 1, and greatly reduces maintenance costs.

[0031] Example 2

[0032] like Figure 3 As shown, Figure 3 This is an exploded structural diagram of Embodiment 2 of the quick-release tooling for the magnetron float of the electric tea stove in the high-speed train.

[0033] In this embodiment, the disassembly rod 5 is set as a bolt, the thread on the bolt is the friction ridge 7, and one end of the bolt is a bolt head 51. The bolt head 51 is detachably installed in the handle 6, thereby realizing the structural setting of the disassembly rod 5. By replacing different types of bolts, the cross-sectional diameter of the disassembly rod 5 can be changed to correspond to different sizes of electric tea stove magnetrons 1.

[0034] Preferably, the disassembly hole 31 is a threaded hole, which can be threaded to the disassembly rod 5, thereby improving the force transmission between the disassembly plug 3 and the disassembly rod 5, and making it easier for the disassembly rod 5 to pull out the disassembly plug 3.

[0035] Generally, the handle 6 includes a handle body and a handle cover 61. The handle body includes a connecting section 62 and a handheld section 63. The connecting section 62 is semi-cylindrical, and the handheld section 63 is cylindrical. The connecting section 62 and the handheld section 63 are coaxially arranged. The handle cover 61 is semi-cylindrical, and the cross-sectional diameters of the connecting section 62, the handheld section 63, and the handle cover 61 are all the same. The connecting section 62 and the handle cover 61 are detachably connected. Both the connecting section 62 and the handle cover 61 are provided with a fixing groove 64 and a through groove 65. The fixing groove 64 of the connecting section 62 and the handle cover 61 forms a fixing cavity, and the bolt head 51 is disposed in the fixing cavity. The through groove 65 of the connecting section 62 and the handle cover 61 forms a through hole, and the disassembly rod 5 is disposed in the through hole and extends out of the through hole.

[0036] Specifically, both the fixing groove 64 and the through groove 65 are semi-circular grooves, and both the fixing groove 64 and the through groove 65 extend along the axis of the corresponding handle body or the handle cover 61, thereby forming the fixing cavity and the disassembly hole 31 with a circular cross-section. The cross-sectional diameter of the fixing groove 64 is larger than the cross-sectional diameter of the through groove 65, so that the bolt head 51 is fixedly engaged in the fixing groove 64, thereby fixing the disassembly rod 5 in the handle 6.

[0037] The connecting section 62 is provided with a first connecting hole 66, and the handle cover 61 is provided with a second connecting hole 67. The first connecting hole 66 and the second connecting hole 67 are provided one-to-one. The first connecting hole 66 is a threaded hole, and the second connecting hole 67 is a through hole. The connecting screw passes through the second connecting hole 67 and is threadedly connected to the corresponding first connecting hole 66, thereby realizing the detachable connection between the handle body and the handle cover 61. After the handle body and the handle cover 61 are connected by the connecting screw, they form an integral cylindrical handle 6.

[0038] Example 3

[0039] In this specific embodiment, the disassembly rod 5 uses a hexagonal head bolt, and the handle body is composed of a semi-cylindrical section 62 with a length of 25.37 mm and a diameter of 16 mm, namely the connecting section 62, and a cylindrical section 63 with a length of 24.63 mm and a diameter of 16 mm, namely the handheld section 63.

[0040] The handle cover 61 is a semi-cylindrical section with a diameter of 16mm and a length of 22mm. There are three first connecting holes 66 and three second connecting holes 67, which are perpendicular to the rectangular surfaces of the corresponding connecting section 62 and the handle cover 61. The three first connecting holes 66 or the two second connecting holes 67 are arranged in a triangular pattern.

[0041] Specifically, one of the second connecting holes 67 is located on the axis of the handle cover 61, 19mm from the front end of the handle cover 61. The front end of the handle cover 61 is the end where the through groove 65 is set. The other two second connecting holes 67 are symmetrically distributed with the axis of the handle cover 61 as the center, and the hole distance between the two symmetrical connecting holes is 10mm.

[0042] The disassembly rod 5 uses a national standard bolt with a nominal diameter of 6mm and a length of 40mm. Its diameter matches the diameter of the disassembly hole 31 below the float bracket 2 of the existing electric tea stove magnetic control.

[0043] The fixed cavity and the through hole formed by the fixed groove 64 and the through groove 65 after assembly are exactly the installation positions of the hexagonal head bolt. Under the clamping of the handle body and the handle cover 61 and the fixing of the connecting screw, the hexagonal bolt can be well fixed, and the various components are assembled to form a whole.
