Description

Technical Field

[0001] The utility model relates to the technical field of disinfection cabinets, in particular to a heating pipe used in disinfection cabinets. Background Art

[0002] At present, heating tubes are used in disinfection cabinets to achieve high-temperature disinfection functions. The heating tubes are generally fixed in the disinfection cabinet by heating tube covers. The heating tube covers are formed by stamping and bending sheet metal parts. A slot is formed inside the heating tube cover, and the end of the heating tube is stuck in the slot. The disadvantage is that the heating tube body is made of glass, and the size error of the heating tube is large, which makes it difficult for the heating tube body to fit exactly with the slot. When the size of the heating tube is small, the heating tube is easy to shake. Furthermore, a wiring terminal is provided at the end of the heating tube body, which makes it easy for the wiring terminal to squeeze the heating tube cover, and there is a risk of the wiring terminal breaking. The wiring terminal is led out from the heating tube cover and connected to the internal circuit of the disinfection cabinet. Since the edge of the heating tube cover is formed by stamping and cutting, the wiring terminal is easy to contact with the sharp edge of the heating tube cover, resulting in damage to the wiring terminal, which makes it easy for the wiring terminal to contact with the heating tube cover and leak electricity.

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example 1, see Figure 1-7 As shown, a heating pipe comprises a heating pipe body 1, a fixing cover 2 and a connecting kit 3. A connection terminal 11 is provided at the end of the heating pipe body 1.

[0022] The fixing cover 2 is provided with a mounting groove 20, and the mounting groove 20 is provided with a clamping position 4 at both ends of the corresponding heating pipe body 1, and the clamping position 4 is provided with a clamping hole 40. One side of the fixing cover 2 is provided with a wire outlet hole 21 connected to the mounting groove 20. Specifically, the clamping position 4 includes two adjacent and left-right symmetrically arranged fixing seats 5, the bottom of the fixing seat 5 is connected and fixed to the fixing cover 2, and the middle part of the two fixing seats 5 facing each other is provided with a recess 51, and the top of the two fixing seats 5 facing each other is provided with a convex part 52, and the clamping hole 40 is formed between the two recesses 51, and the gap between the two convex parts 52 is smaller than the diameter of the fixing section. In this embodiment, the fixing seat 5 is formed by stamping and bending the fixing cover 2.

[0023] The connection kit 3 includes a fixed section 6 and a lead-out section 7, and the fixed section 6 and the lead-out section 7 are connected and fixed in an L-shape. A positioning hole 60 is provided in the fixed section 6, and a through hole 70 is provided in the lead-out section 7. The inner ends of the positioning hole 60 and the through hole 70 are connected. The positioning hole 60 and the end of the heating tube body 1 are non-circularly matched. A clearance groove 61 is provided on the outer periphery of the fixed section 6 near one end of the lead-out section 7.
