Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0027] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0028] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0029] When in use, the circular plate on the electric heating tube is installed on the flange of the pipe to be heated by bolts, and then the electric heating tube is turned on to convert electrical energy into thermal energy. However, during the installation of the tubular electric heater and the flange, the hole spacing of each mounting hole on the mounting plate of the tubular electric heater cannot be adjusted, and a flange matching the hole spacing of each mounting hole on the mounting plate is required for installation and fixation, which limits the installation and connection of the tubular electric heater and is inconvenient for the installation and use of the tubular electric heater.

[0030] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a tubular electric heating element. When it is needed, it is only necessary to open the electric push rod 24, adjust the lateral position of the plate body 22, open the adjustment mechanism 28, rotate the ring body 25, and adjust the angle of the electric push rod 24, so that the electric push rod 24 drives the plate body 22 to rotate in the groove body 21, thereby increasing the adjustment range. Subsequently, after the bolt is passed through the center hole of the plate body 22, the mounting plate 11 is fixed, which is more convenient and quick, and improves the practicality of the device.

[0031] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0032] Combination Figure 1-Figure 3 The embodiment of the present application provides a tubular electric heating element, including a main body component 1; the main body component 1 includes: a mounting plate 11, on which a protective cover 12 is arranged; a heating tube 13, which is arranged on the mounting plate 11; an adjustment component 2 is arranged on the mounting plate 11; the adjustment component 2 includes: a groove body 21, which is opened on the mounting plate 11; a plate body 22, which is arranged in the groove body 21; a turntable 23, which is rotatably connected to the mounting plate 11; an electric push rod 24, which is fixedly connected to the turntable 23, and the output end of the electric push rod 24 is fixedly connected to the plate body 22; a ring body 25, which is rotatably connected to the heating tube 13; a limit block 26, which is arranged on the electric push rod 24; a limit groove 27, which is opened on the ring body 25, and the electric push rod 24 is embedded in the limit block 26; an adjustment mechanism 28, which is arranged on the mounting plate 11, and the adjustment mechanism 28 is used to adjust the angle of the ring body 25.

[0033] When in use, the electric push rod 24 is opened, so that the output end of the electric push rod 24 is extended, and the plate body 22 is pushed to slide in the groove body 21 to adjust the lateral position of the plate body 22, or the adjustment mechanism 28 is opened to make the ring body 25 rotate on the protective cover 12. While rotating, multiple limit blocks 26 are moved in multiple limit grooves 27. While moving, the electric push rod 24 and the turntable 23 are pushed to rotate on the mounting plate 11 through the limit blocks 26 to adjust the angle of the electric push rod 24. When the electric push rod 24 rotates, it drives the plate body 22 to move in the groove body 21. After the adjustment is appropriate, the adjustment mechanism 28 is closed, and then the bolt is passed through the center hole of the plate body 22, and the mounting plate 11 is fixed to complete the installation.

[0034] In some embodiments, the adjustment mechanism 28 includes a motor, a gear and a rack. By turning on the motor, the motor drives the ring body 25 to rotate through the meshing of the gear and the rack.

[0035] In some embodiments, the groove body 21, the plate body 22, the turntable 23, the electric push rod 24, the limit block 26 and the limit groove 27 are a group, and at least three groups are arranged on the mounting plate 11 to achieve simultaneous adjustment of the positions of multiple plate bodies 22.

[0036] In some embodiments, the plate body 22 is tightly attached to the slot body 21, and the slot body 21 is a stepped hole that passes through the top of the mounting plate 11 to improve stability.

[0037] In some embodiments, a disassembly assembly 3 is provided on the mounting plate 11; the disassembly assembly 3 includes: a fixing block 31, which is provided on the mounting plate 11; a bolt 1 32, which is threadedly connected to the mounting plate 11, and the motor is installed on the fixing block 31; and a bolt 2 33, which is threadedly connected to the ring body 25.

[0038] When in use, bolt 1 32 is rotated to disengage the fixing block 31 from the mounting plate 11, thereby realizing the disassembly of the motor and the gear. At this time, the ring body 25 is directly rotated to make the ring body 25 rotate directly, and finally the ring body 25 is fixed by bolt 2 33, so that manual adjustment can be performed while supporting electric adjustment, thereby improving practicality.

[0039] In some embodiments, a plurality of bolts 33 are provided to improve the fixing effect.

[0040] In some embodiments, a slot is provided on the mounting plate 11 , and the fixing block 31 is embedded in the slot, so as to facilitate installation of the fixing block 31 .

[0041] In some embodiments, the adjustment mechanism 28 is installed between two adjacent plates 22 to prevent the adjustment mechanism 28 from affecting the normal adjustment of the plates 22 .

[0042] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.
