[0002] U-shaped heating tube, also known as heterogeneous heating tube, is a tubular electric heating element. Its unique design and efficient heating performance have been widely used in many fields. The U-shaped heating tube is mainly composed of a seamless metal tube, a heating wire and a mounting base. The heating wire is placed in the metal tube, and the gap in the tube is tightly filled with crystalline magnesium oxide powder with good thermal conductivity and insulation. The two ends of the heating wire are connected to the power supply through two lead rods to form a complete circuit.

[0003] Since the heating tube is used in water for a long time, scale is easily generated on the surface of the heating tube due to various reasons such as water quality. Therefore, when the heating tube needs to be maintained or replaced, the process of disassembly and installation is indispensable. However, the existing U-shaped heating tube and the mounting base are generally fixed with bolts and threaded holes. Therefore, it is necessary to disassemble and install the U-shaped heating tube from the mounting base, which is a relatively time-consuming operation. Utility Model Content

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0021] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] like Figures 1-6 As shown, a quick-install U-shaped heating tube includes a heating tube 1, a fixing sleeve 3 is fixedly installed on the outside of the heating tube 1, a mounting base 4 with a hollow structure is provided on the outside of the heating tube 1, entry holes 5 are opened on both sides of the top of the mounting base 4, and a sealing component is arranged between the entry hole 5 and the fixing sleeve 3 to ensure the sealing between the entry hole 5 and the fixing sleeve 3. The sealing component includes: a spring a201, an upper gasket 202, a lower gasket 203 and a spring sleeve 2. A snap assembly is arranged between the heating tube 1 and the mounting base 4 to fix the fixing sleeve 3. The snap assembly includes: a buckle block 501, a spring b502, a control rod 503 and a limit sleeve 506.

[0023] Among them, an upper gasket 202 with a circular ring structure is provided on the outside of the fixed sleeve 3, a spring sleeve 2 with a circular ring structure is provided at the bottom of the upper gasket 202, the inside of the spring sleeve 2 is a hollow structure, a spring a201 with a circular ring structure is provided inside the spring sleeve 2, and a lower gasket 203 with a circular ring structure is provided at the bottom of the spring sleeve 2.

[0024] When the heating tube 1 needs to be installed on the mounting base 4, since the fixing sleeve 3 is installed on the outside of the heating tube 1, the bottom of the fixing sleeve 3 can be directly passed through the corresponding upper gasket 202, spring sleeve 2, lower gasket 203 and entry hole 5, so that the bottom end of the fixing sleeve 3 can be inserted into the interior of the mounting base 4, and the fixing sleeve 3 will squeeze the upper gasket 202 and the lower gasket 203 when passing through the entry hole 5, and deform outward. Since the upper gasket 202 and the lower gasket 203 are made of silicone material, which has good elasticity, after the fixing sleeve 3 passes through the upper gasket 202 and the lower gasket 203, the upper gasket 202 and the lower gasket 203 are The inner wall can fit tightly with the outer side of the fixing sleeve 3 through its elasticity, ensuring the sealing effect between the upper gasket 202 and the lower gasket 203 and the fixing sleeve 3, and when the fixing sleeve 3 passes through the spring sleeve 2, the spring a201 is expanded outward. Due to the elastic force of the spring a201, the spring sleeve 2 can be driven to shrink inward, so that the inner wall of the spring sleeve 2 is tightly fitted with the fixing sleeve 3, further improving the sealing between the fixing sleeve 3 and the spring sleeve 2. Since the lower gasket 203 is installed on the top of the mounting base 4, after ensuring the sealing between the lower gasket 203, the spring sleeve 2 and the upper gasket 202 and the fixing sleeve 3, the sealing between the entry hole 5 and the fixing sleeve 3 can be strengthened.

[0025] When the locking nut 505 is unlocked, the locking nut 506 is unlocked, and the locking nut 506 is unlocked, so that the locking nut 506 can be unlocked.

[0026] Among them, two through holes 504 are opened on one side of the outer end of the mounting base 4, and one end of the two control rods 503 respectively passes through the two through holes 504 and extends to the inside of the mounting base 4. The through holes 504 can ensure that one end of the control rod 503 can extend to the inside of the mounting base 5 and connect with the buckle block 501, so the user can drive the buckle block 501 to rotate through the control rod 503.

[0027] Among them, a sliding opening 507 is opened on one side of the outer end of the limiting sleeve 506, and the bottom of the limiting sleeve 506 is connected to the inner wall of the mounting base 4. The sliding opening 507 can limit the rotation range of the buckle block 501 to prevent the buckle block 501 from rotating too much and damaging the spring b502.

[0028] Among them, two exit holes 6 corresponding to the inlet holes 5 are opened on both sides of the bottom of the mounting base 4, and electrode heads 7 are provided at both ends of the bottom of the heating tube 1. The two fixing sleeves 3 pass through the two inlet holes 5 and the two exit holes 6 respectively and protrude from the bottom of the mounting base 4. The exit holes 6 allow the fixing sleeve 3 and one end of the heating tube 1 to protrude from the lower surface of the mounting base 4, and the electrode head 7 is a key connecting component between the heating tube 1 and the external power supply.

[0029] Working principle: When the heating tube 1 needs to be installed on the mounting base 4, since the fixing sleeve 3 is installed on the outside of the heating tube 1, the bottom of the corresponding fixing sleeve 3 can be directly passed through the corresponding upper gasket 202, spring sleeve 2, lower gasket 203 and entry hole 5, so that the bottom end of the fixing sleeve 3 can be inserted into the inside of the mounting base 4, and the fixing sleeve 3 will squeeze the upper gasket 202 and the lower gasket 203 when passing through the entry hole 5, and deform outward. Since the upper gasket 202 and the lower gasket 203 are made of silicone material, the silicone material has good elasticity. Therefore, after the fixing sleeve 3 passes through the upper gasket 202 and the lower gasket 203, the inner walls of the upper gasket 202 and the lower gasket 203 can fit tightly with the outside of the fixing sleeve 3 through its elasticity, and when the fixing sleeve 3 passes through the spring sleeve 2, the spring a201 is expanded outward, and the elastic force of the spring a201 can drive the spring sleeve 2 shrinks inwardly, so that the inner wall of the spring sleeve 2 fits tightly with the fixing sleeve 3, thereby ensuring the sealing between the entry hole 5 and the fixing sleeve 3. Before the fixing sleeve 3 passes through the entry hole 5 and enters the interior of the mounting base, it is necessary to pull the control rod 503 in advance to drive the buckle block 501 to rotate clockwise, and the control rod 503 can stretch the spring b502 when rotating. At this time, the fixing sleeve 3 is inserted into the interior of the mounting base through the entry hole 5 until the buckle notch 505 on one side of the fixing sleeve 3 moves to the position opposite to the buckle block 501. The contraction force of the spring b502 drives the buckle block 501 and the control rod 503 to rotate counterclockwise until one end of the buckle block 501 is inserted into the buckle notch 505. Since one end of the buckle block 501 is engaged in the buckle notch 505, the position of the fixing sleeve 3 and the heating tube 1 can be fixed. At this point, the heating tube 1 has been installed on the mounting base 4.
