[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] A heater, such as Figure 1 and Figure 2 , including a fixed plate 1, a heating tube 2, a bracket 3 and a rotating frame 4. The bracket 3 is located above the fixed plate 1, and the fixed plate 1 is provided with a rotating member for driving the bracket 3 to rotate. The heating tube 2 is arranged on the rotating frame 4. A groove 5 is opened on one side of the bracket 3. The rotating frame 4 is vertically located in the groove 5. Rotating grooves 6 are opened above the groove walls on both sides of the opposite sides of the groove 5. The two rotating grooves 6 are rotatably connected with rotating shafts 7. One end of the two rotating shafts 7 is fixedly connected to the rotating frame 4. The bracket 3 is provided with a first limiting member for limiting the rotation of the rotating shaft 7.

[0032] like Figure 1 and Figure 2 and Figure 3The initial position of the rotating frame 4 is vertically located in the groove 5, and the bracket 3 is driven to rotate horizontally by the rotating member. At this time, the bracket 3 drives the rotating frame 4 and the heating tube 2 to rotate along the rotation axis of the bracket 3. At this time, the heating direction of the heating tube 2 can be adjusted, thereby increasing the heating area of ​​the heater. By releasing the restriction of the rotating shaft 7 by the first limiting member and pulling the rotating frame 4, the rotating frame 4 is rotated upward through the cooperation of the rotating shaft 7 and the rotating groove 6, and the end of the rotating frame 4 away from the rotating shaft 7 is rotated out of the groove 5 until the rotating frame 4 is rotated upward to a horizontal position. At this time, the heating direction of the heating tube 2 is downward, and then the rotation of the rotating shaft 7 is restricted by the first limiting member so that the rotating frame 4 remains in a horizontal state. At this time, the heating direction of the heating tube 2 can be further adjusted, which is simple and convenient to use.

[0033] like Figure 2The first limiting member includes a snap ring 8 and an annular groove 9 provided on one side of the rotating frame 4. The annular groove 9 is coaxially arranged with the rotating shaft 7. The snap ring 8 is located in the annular groove 9. The bottom of the annular groove 9 is evenly distributed with a plurality of grooves 10 along the circumference of the annular groove 9. The side of the snap ring 8 close to the groove 10 is provided with a clamping block 12 horizontally inserted into one of the grooves 10. The side of the snap ring 8 away from the bottom of the annular groove 9 is horizontally provided with two opposite first rods 13. The bracket 3 is provided with a slot 14 for horizontally inserting the two first rods 13 away from the snap ring 8. The two slots 1 A compression spring 15 is provided between the bottom of the slot 4 and the first rod 13. A second rod 16 is horizontally provided at one end of the two first rods 13 close to the compression spring 15. A connecting groove 17 is provided at the bottom of the two slots 14 for the second rod 16 to pass horizontally away from the end of the first rod 13. The ends of the two first rods 13 passing through the connecting groove 17 are connected by a third rod 18. The third rod 18 is located outside the slot 14, and a pull ring 19 is provided on the side of the third rod 18 away from the second rod 16. The purpose of this setting is that when the restriction on the rotating shaft 7 needs to be released, only the pull ring 19 needs to be pulled. The ring 19 drives the snap ring 8 to move horizontally in the annular groove 9 in the direction away from the bottom of the annular groove 9 through the third rod 18, the two second rods 16, and the two first rods 13. The compression spring 15 is compressed until the blocks 12 on the snap ring 8 are all moved out of the grooves 10 and separated from the grooves 10. At this time, the restriction on the rotating shaft 7 can be released. When the rotating frame 4 is pulled so that the rotating frame 4 rotates upward through the cooperation of the rotating shaft 7 and the rotating groove 6, the snap ring 8 will not rotate with the rotating frame 4. When the rotating frame 4 rotates upward to a horizontal position, one of the grooves 10 and the block 12 Align, then release the pull ring 19. At this time, the compressed compression spring 15 will push the two first rods 13 to drive the third rod 18, the two second rods 16, and the snap ring 8 to move horizontally toward the bottom of the annular groove 9 until the block 12 on the snap ring 8 is horizontally inserted into the aligned slot 10. At this time, the cooperation of the block 12, the slot 10, the snap ring 8, the two first rods 13, the two slots 14 and the compression spring 15 can limit the rotation of the rotating frame 4 through the cooperation of the rotating shaft 7 and the rotating groove 6, thereby limiting the rotation of the rotating shaft 7. It is simple and convenient to use.

[0034] like Figure 1 and Figure 3 The top surface of the rotating frame 4 is an arc-shaped surface, and a first right-angled triangular plate 20 is provided on the bottom groove wall of the groove 5. The bottom end of the rotating frame 4 is provided with a second right-angled triangular plate 21 that cooperates with the upper inclined surface of the first right-angled triangular plate 20. The purpose of this arrangement is to limit the rotation direction of the rotating frame 4 through the cooperation of the first right-angled triangular plate 20 and the second right-angled triangular plate 21, so that the rotating frame 4 can only rotate upward counterclockwise through the cooperation of the rotating shaft 7 and the rotating groove 6. When the rotating frame 4 rotates upward counterclockwise to a horizontal state, the heating direction of the heating tube 2 is downward, which is simple and convenient to use.

[0035] like Figure 1 The rotating member includes two first support rods 22 relatively arranged at the top of the fixed plate 1, and the top ends of the two first support rods 22 are connected by a second support rod 23, and the bottom end of the second support rod 23 is rotatably connected to the turntable 24. The bottom end of the bracket 3 is provided with a support plate 25, which is arranged at the top of the turntable 24, and the support plate 25 is coaxially arranged with the turntable 24. A placement groove 26 is opened on the support plate 25, and the second support rod 23 is located in the placement groove 26. There is a distance between the opposite sides of the second support rod 23 and the groove wall of the placement groove 26. A driving member for driving the turntable 24 to rotate back and forth is provided between the two first support rods 22. The purpose of this arrangement is to When the bracket 3 needs to rotate horizontally, it is only necessary to drive the turntable 24 to rotate back and forth through the driving member. At this time, because the bracket 3 is arranged at the top of the support plate 25, and the support plate 25 is arranged at the top of the turntable 24, when the turntable 24 rotates back and forth, the turntable 24 will drive the support plate 25 and the bracket 3 to rotate back and forth. The reciprocating angle of the turntable 24 is 30 degrees clockwise and 30 degrees counterclockwise. Because the second support rod 23 is located in the placement groove 26, there is a gap between the second support rod 23 and the groove wall of the placement groove 26. Therefore, when the turntable 24 rotates back and forth, the second support rod 23 will not affect the turntable 24 driving the support plate 25 to rotate, which is simple and convenient to use.

[0036] like Figure 4 and Figure 5The driving member includes a roller 27 rotatably connected between the two first support rods 22, and a first fixed cylinder 28 and a second fixed cylinder 29 are coaxially fixedly connected to the roller 27. The first fixed cylinder 28 and the second fixed cylinder 29 are arranged opposite to each other. The bottom end of the turntable 24 is provided with a plurality of first driving rods 30 at intervals along the circumference of the turntable 24. The outer walls of the first fixed cylinder 28 and the second fixed cylinder 29 are provided with four first driving teeth 31 that mesh with the first driving rod 30. One of the first support rods 22 is provided with a first motor 32 for driving the roller 27 to rotate. The purpose of this arrangement is that when it is necessary to drive the turntable 24 to rotate back and forth, it is only necessary to turn on the first motor 32. At this time, the rotating shaft of the first motor 32 drives the roller 27 to rotate, and the roller 27 drives the first fixed cylinder 28 and the second fixed cylinder 29 to rotate. At this time, the first fixed cylinder 28 and the second fixed cylinder 29 are both The first driving tooth 31 is driven to rotate along the rotation axis of the rotating roller 27. At this time, the first driving tooth 31 on the first fixed cylinder 28 first engages with the first driving rod 30 on the turntable 24 and drives the turntable 24 to rotate clockwise. When the turntable 24 rotates 30 degrees clockwise, the first driving tooth 31 on the first fixed cylinder 28 is separated from the first driving rod 30 on the turntable 24, and the first driving tooth 31 on the second fixed cylinder 29 is engaged with the first driving rod 30 on the turntable 24 and drives the turntable 24 to rotate counterclockwise by 30 degrees. When the turntable 24 rotates 30 degrees counterclockwise, the first driving tooth 31 on the second fixed cylinder 29 is separated from the first driving rod 30 on the turntable 24, and the first driving tooth 31 on the first fixed cylinder 28 engages with the first driving rod 30 on the turntable 24 again. The above process is repeated to realize the reciprocating rotation of the turntable 24, which is simple and convenient to use.

[0037] like Figure 6 and Figure 7The drive member includes a first rotating column 33 coaxially fixedly connected to the bottom end of the turntable 24 and a disk 34 arranged at the bottom end of the first rotating column 33. A horizontal plate 35 is horizontally provided between the two first support rods 22. The top of the horizontal plate 35 is rotatably connected to two second rotating columns 36. The tops of the two second rotating columns 36 are respectively provided with a first gear 37 and a second gear 38. The first gear 37 and the second gear 38 are meshed and are both located above the disk 34. A plurality of second gears are evenly distributed on the side wall of the disk 34 along the circumference of the disk 34. The bottom ends of the driving teeth 39, the first gear 37 and the second gear 38 are all provided with four second driving rods 40 that mesh with the second driving teeth 39. The bottom end of the horizontal plate 35 is provided with a second motor 41 for driving the second rotating column 36 provided with the first gear 37 to rotate. The purpose of this arrangement is that when it is necessary to drive the turntable 24 to rotate back and forth, it is only necessary to turn on the second motor 41. At this time, the rotating shaft of the second motor 41 drives the second rotating column 36 provided with the first gear 37 to rotate, and the second rotating column 36 drives the first gear 37 to rotate. The first gear 37 drives the second gear 38 meshed with it to rotate, and the four second driving rods 40 on the first gear 37 rotate along the rotation axis of the first gear 37, and the four second driving rods 40 on the second gear 38 rotate along the rotation axis of the first gear 37. At this time, the second driving rod 40 on the first gear 37 first meshes with the second driving teeth 39 on the disk 34 and drives the turntable 24 clockwise through the disk 34. When the turntable 24 rotates 30 degrees clockwise, the second driving rod 40 on the first gear 37 and the second driving rod 40 on the disk 34 The second drive teeth 39 are separated, and the second drive rod 40 on the second gear 38 is engaged with the second drive teeth 39 on the disk 34 and drives the turntable 24 to rotate counterclockwise by 30 degrees through the disk 34. When the turntable 24 rotates counterclockwise by 30 degrees, the second drive rod 40 on the second gear 38 is separated from the second drive teeth 39 on the disk 34, and the second drive rod 40 on the first gear 37 is engaged with the second drive teeth 39 on the disk 34 again. The above process is repeated to realize the reciprocating rotation of the turntable 24, which is simple and convenient to use.

[0038] like Figure 4 Two opposite vertical rods 42 are provided at the top of the fixed plate 1, and the tops of the two vertical rods 42 are provided with balls 43 that abut against the bottom end of the turntable 24. The purpose of this setting is that the turntable 24 can be supported by the cooperation between the vertical rods 42 and the balls 43, thereby reducing the situation where the end of the turntable 24 away from the rotation point of the turntable 24 and the second support rod 23 bends downward due to gravity or stepping, which is simple and convenient to use.

[0039] like Figure 3 and Figure 4The support plate 25 includes a first plate 44 and a second plate 45, the second plate 45 is rotatably connected to the bottom end of the first plate 44, the second plate 45 is arranged at the top end of the turntable 24, and the placement slot 26 is opened on the second plate 45. The top end of the first plate 44 is horizontally slidably connected to a movable plate 46 by a moving member, and the bracket 3 is arranged at the top end of the movable plate 46. The first plate 44 is provided with a second limiting member for limiting the first plate 44 from rotating on the second plate 45. The purpose of this setting is to drive the movable plate 46 to move horizontally on the first plate 44 by the moving member. At this time, the position of the bracket 3 on the first plate 44 can be adjusted. By releasing the restriction of the first plate 44 by the second limiting member, and then manually rotating the first plate 44, the position of the bracket 3 can be further adjusted. After the position adjustment of the bracket 3 is completed, the first plate 44 is restricted by the second limiting member so that it cannot rotate on the second plate 45. When the turntable 24 rotates, the turntable 24 drives the second plate 45 to rotate, and the first plate 44 follows the second plate 45 to rotate through the second limiting member. At this time, the bracket 3 rotates along the rotation axis of the second plate 45, which is simple and convenient to use.

[0040] like Figure 3 and Figure 4 The movable member includes a long strip slide 51 provided at the top of the first disk 44 and connected to one side of the first disk 44. The movable plate 46 is horizontally slidably connected in the slide 51. A groove wall on one side of the slide 51 is rotatably connected to a screw rod 52, and one end of the screw rod 52 passes through the movable plate 46 and is threadedly connected to the movable plate 46. The screw rod 52 is horizontally arranged along the length direction of the slide 51. The first disk 44 is provided with a third motor 53 for driving the screw rod 52 to rotate. The purpose of this arrangement is that when it is necessary to drive the movable plate 46 to move horizontally on the first disk 44, it is only necessary to turn on the third motor 53. At this time, the rotating shaft of the third motor 53 drives the screw rod 52 to rotate. Because one end of the screw rod 52 passes through the movable plate 46 and is threadedly connected to the movable plate 46, the movable plate 46 is horizontally slidably connected in the slide 51, so when the screw rod 52 rotates, the movable plate 46 can be driven to move horizontally on the first disk 44, which is simple and convenient to use.

[0041] like Figure 3 and Figure 4 The second limiting member includes an annular limiting groove 47 coaxially arranged at the top of the second disk 45 and a threaded groove 48 opened at the top of the first disk 44. A bolt 49 is threadedly connected to the threaded groove 48, and one end of the bolt 49 extends vertically into the limiting groove 47 and is provided with a rubber anti-slip pad 50 that abuts against the bottom of the limiting groove 47. The purpose of this setting is to tighten the bolt 49 so that the rubber anti-slip pad 50 at the bottom of the bolt 49 enters the limiting groove 47 and abuts against the bottom of the limiting groove 47. At this time, the first disk 44 can be restricted so that it cannot rotate on the second disk 45 and only needs to rotate with the second disk 45. It is simple and convenient to use.
