[0002] The main function of a heating element assembly is to convert electrical energy into heat energy for purposes such as heating, drying, and heat preservation. A heating element assembly typically consists of a metal outer protective tube, lead wires, a thermal protector, magnesium oxide powder, and sealing material. The metal outer protective tube serves to prevent corrosion, moisture, and heat dissipation; the lead wires connect to the power cord and remain inside the heating element as a non-heating component; the thermal protector automatically disconnects the heating element when the temperature exceeds a certain limit; the magnesium oxide powder fixes the center of the resistance wire, protects the metal casing from being charged, and transfers heat; the sealing material ensures the heating element has good electrical insulation properties.

[0003] The existing heating element assembly is fixed to a sturdy frame, and the plastic bracket is fixed to the connector. For easy replacement and maintenance, the plastic bracket is bolted to the sturdy frame. However, the existing safety heating element assembly with a full-frame plastic bracket still has the following problems during use:

[0004] When existing heating tubes vibrate during operation, the bolts used for fixing the sturdy frame and plastic bracket can easily loosen, affecting the installation and use of the equipment. Therefore, it is necessary to develop a safe heating tube assembly with a full-frame plastic bracket for use in the field of existing heating tube assemblies. Utility Model Content

The stable frame is provided with multiple mounting holes, and bolts are threaded onto the mounting holes. The stable frame is provided with multiple traction ports, which are located on one side of the mounting holes and are symmetrically fixed. Each traction port is equipped with a guide rod, and both guide rods are movable. Each guide rod is equipped with a sliding block, the top of which is fixed. Each sliding block is equipped with a limit block, and both symmetrical sides of the sliding block are fixed. A connecting block is provided, and the connecting block is located inside the stable frame.

[0008] Preferably, the connecting block has an inner cavity, on which a telescopic spring is fixedly mounted. The top of the telescopic spring is fixedly mounted with a push plate, and a telescopic button is fixedly mounted on the push plate.

[0009] Preferably, one end of the telescopic button extends through the connecting block, and the one end of the telescopic button can be engaged with one of the first and second locking holes.

[0010] Preferably, the sturdy frame is provided with a bayonet, a plastic bracket is snapped into the bayonet, and multiple inserts are fixedly mounted on the plastic bracket, each insert having an assembly hole.

[0011] Preferably, the assembly hole coincides with the mounting hole, and the bolt is threaded into the mounting hole and the assembly hole of the insert block, respectively.

[0012] The advantages of this utility model are:

[0013] This utility model connects the plastic bracket to the snap-fit ​​on the sturdy frame. The insert is located inside the sturdy frame, and the mounting hole on the insert coincides with the mounting hole. Bolts are installed on the mounting hole and the mounting hole of the insert to fix the sturdy frame and the plastic bracket. When disassembling and maintaining the heating tube assembly on the sturdy frame, only the sturdy frame and the plastic bracket need to be disassembled and reassembled, while the plastic bracket remains installed on the connector, improving the operation efficiency. Pressing the telescopic button causes the push plate to move downward, the telescopic spring to retract, and the guide rod on the traction port moves the sliding block until the telescopic button engages with the second snap-fit ​​hole. At this time, the limit block is located above the bolt, and the limit block restricts the movement of the bolt to prevent the bolt from loosening. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0027] This application discloses a safety heating tube assembly with a full-frame plastic support. (Refer to...) Figure 2 - Figure 4A safety heating tube assembly with a full-frame plastic bracket is assembled on a stable frame 10. The stable frame 10 has multiple mounting holes 31, with bolts 40 threaded onto each hole 31. The stable frame 10 also has multiple traction ports 12, each located on one side of a mounting hole 31. Guide rods 13 are symmetrically fixed to each traction port 12, and sliding blocks 20 are movably mounted on each guide rod 13. Limit blocks 21 are fixedly mounted on the top of each sliding block 20. Connecting blocks 41 are fixedly mounted on both symmetrical sides of each sliding block 20, located inside the stable frame 10. The stable frame 10 has multiple sets of first locking holes 22 and multiple sets of second locking holes 23, each located on one side of a first locking hole 22. Each set of first locking holes 22 and each set of second locking holes 23 consists of two holes. The first locking hole 22 and the two second locking holes 23 of each group are located on both sides of the traction port 12. The interior of the connecting block 41 is provided with an inner cavity 43. A telescopic spring 50 is fixedly mounted on the inner cavity 43. A push plate 51 is fixedly mounted on the top of the telescopic spring 50. A telescopic button 42 is fixedly mounted on the push plate 51. One end of the telescopic button 42 moves through the connecting block 41 and can engage with one of the first locking holes 22 and the second locking holes 23. A bolt 40 is installed on the mounting hole 31. The telescopic button 42 is pressed, causing the push plate 51 to move downward and the telescopic spring 50 to retract. The guide rod 13 on the traction port 12 moves the sliding block 20 until the telescopic button 42 engages with the second locking hole 23. At this time, the limiting block 21 is located above the bolt 40. The limiting block 21 restricts the movement of the bolt 40 and prevents the bolt 40 from loosening.

[0028] Reference Figure 1 and Figure 2 The stabilizing frame 10 is provided with a bayonet 30, on which a plastic bracket 11 is snapped. Multiple inserts 32 are fixedly mounted on the plastic bracket 11. Each insert 32 has an assembly hole 33 that coincides with the mounting hole 31. Bolts 40 are threaded into the mounting hole 31 and the assembly hole 33 of the insert 32, respectively, to snap the plastic bracket 11 into the bayonet 30 on the stabilizing frame 10. The inserts 32 are located inside the stabilizing frame 10, and the assembly holes 33 on the inserts 32 coincide with the mounting hole 31. Bolts 40 are installed on the mounting hole 31 and the assembly hole 33 of the inserts 32 to fix the stabilizing frame 10 and the plastic bracket 11. When disassembling and maintaining the heating tube assembly on the stabilizing frame 10, it is only necessary to disassemble and assemble the stabilizing frame 10 and the plastic bracket 11. The plastic bracket 11 is still installed on the connector, improving the operation efficiency.

[0029] Working principle: The plastic bracket 11 is engaged with the latch 30 on the stabilizing frame 10. The insert 32 is located inside the stabilizing frame 10. At this time, the mounting hole 33 on the insert 32 coincides with the mounting hole 31. Bolts 40 are installed on the mounting hole 31 and the mounting hole 33 of the insert 32 to fix the stabilizing frame 10 and the plastic bracket 11. When disassembling and maintaining the heating tube assembly on the stabilizing frame 10, it is only necessary to disassemble and assemble the stabilizing frame 10 and the plastic bracket 11. The plastic bracket 11 is still installed on the connector, improving the operation efficiency. Pressing the telescopic button 42 causes the push plate 51 to move downward and the telescopic spring 50 to retract. The guide rod 13 on the traction port 12 moves the sliding block 20 until the telescopic button 42 engages with the second latch 23. At this time, the limit block 21 is located above the bolt 40. The limit block 21 restricts the movement of the bolt 40 and prevents the bolt 40 from loosening.
