As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] like Figures 1-4 As shown, this utility model embodiment provides an electric heater fastening device, including a clamping assembly 1. The clamping assembly 1 includes a fixed base 11, a mounting groove 12, a bidirectional synchronous motor 13, an adjusting screw 14, a sliding groove 15, a clamping arm 16, an adjusting screw hole 17, a clamping plate 18, a first anti-slip pad 19, and an electric heater body 20.
[0028] A mounting groove 12 is provided at the center of the upper surface of the fixed base 11. A bidirectional synchronous motor 13 is fixedly connected to the inner wall of the mounting groove 12. Adjusting screws 14 are fixedly connected to both output ends of the bidirectional synchronous motor 13. The ends of the two adjusting screws 14 that are far apart pass through the center of the inner wall of the mounting groove 12. Sliding grooves 15 are provided on both sides of the upper surface of the fixed base 11. Clamping arms 16 are slidably connected to the inner wall of the two sliding grooves 15. An adjusting screw hole 17 is provided on the lower part of one side of the clamping arm 16. The outer wall of the adjusting screw 14 is threaded to the inner wall of the adjusting screw hole 17. The sides of the two clamping arms 16 that are close to each other are... Clamping plates 18 are welded to the upper part of the adjustment screw holes 17. First anti-slip pads 19 are fixedly connected to the adjacent sides of the two clamping plates 18. The electric heater body 20 is attached to the middle of the upper surface of the fixing base 11. The adjacent sides of the two first anti-slip pads 19 are attached to the two sides of the electric heater body 20. The two adjusting screws 14 are rotated by the bidirectional synchronous motor 13, which drives the two clamping arms 16 to move closer together, so that the first anti-slip pads 19 on the two clamping plates 18 are tightly attached to the two sides of the electric heater body 20, thereby limiting and fixing the electric heater body 20 and preventing the electric heater body 20 from moving left and right.
[0029] In one embodiment, specifically: connecting blocks 21 are welded to the top of both clamping arms 16, and first limiting screw holes 22 are opened on the adjacent sides of the upper surfaces of the two connecting blocks 21. A first limiting screw 23 is threaded to the inner wall of the first limiting screw hole 22, and a U-shaped limiting frame 24 is rotatably connected to the bottom of the outer wall of the first limiting screw 23. A second anti-slip pad 25 is fixedly connected to the inner top wall of the U-shaped limiting frame 24. The lower surface of the second anti-slip pad 25 is attached to one side of the upper surface of the electric heater body 20. By rotating the first limiting screw 23, the U-shaped limiting frame 24 is driven to move downward, so that the second anti-slip pad 25 on the U-shaped limiting frame 24 is tightly attached to the upper surface of the electric heater body 20, thereby limiting the top of the electric heater body 20 and preventing the electric heater body 20 from moving up and down.
[0030] In one embodiment, specifically: the lower part of the front and rear surfaces of the U-shaped limiting frame 24 are provided with second limiting screw holes 26, the inner sidewalls of the two second limiting screw holes 26 are threaded with second limiting screws 27, the outer sidewalls of the two second limiting screws 27 are rotatably connected to limiting disks 28, and the adjacent sides of the two limiting disks 28 are fixedly connected with elastic protective pads 29. By rotating the second limiting screws 27, the limiting disks 28 are moved, thereby making the elastic protective pads 29 on the limiting disks 28 fit tightly with the heat dissipation fins 30 on the electric heater body 20, preventing the electric heater body 20 from moving back and forth.
[0031] In one embodiment, specifically: heat dissipation fins 30 are provided on both the front and rear surfaces of the electric heater body 20, and the adjacent sides of two elastic protective pads 29 are respectively attached to the opposite sides of the two heat dissipation fins 30. The elastic protective pads 29 not only increase the friction at the contact points with the heat dissipation fins 30, but also protect the heat dissipation fins 30.
[0032] In one embodiment, specifically: a first limiting groove 31 is provided in the middle of the inner front wall and the inner rear wall of the sliding groove 15, and a first limiting block 32 is fixedly connected to the lower part of the front surface and the rear surface of the clamping arm 16. The outer side wall of the first limiting block 32 is slidably connected to the inner side wall of the first limiting groove 31. By sliding the first limiting block 32 on the clamping arm 16 inside the first limiting groove 31, the first limiting block 32 is limited, thereby increasing the stability of the movement of the clamping arm 16.
[0033] In one embodiment, specifically: a second limiting block 33 is fixedly connected to the middle of the side of the U-shaped limiting frame 24 near the clamping arm 16, and a second limiting groove 34 is opened on the upper part of one side of the clamping arm 16. The outer side wall of the second limiting block 33 away from the U-shaped limiting frame 24 is slidably connected to the inner side wall of the second limiting groove 34. By sliding the second limiting block 33 on the U-shaped limiting frame 24 inside the second limiting groove 34, the second limiting block 33 is limited, thereby increasing the stability of the U-shaped limiting frame 24 moving up and down.
[0034] In one embodiment, specifically: a first knob 35 is fixedly connected to the top of the first limiting screw 23, and a second knob 36 is fixedly connected to the end of the second limiting screw 27 away from the limiting disk 28. The first limiting screw 23 and the second limiting screw 27 can be rotated by the first knob 35 and the second knob 36.
[0035] In one embodiment, specifically: mounting holes 37 are provided at the four corners of the upper surface of the fixing base 11, and the fixing base 11 can be fixedly installed by using bolts or other connecting parts through the mounting holes 37 at the four corners of the upper surface of the fixing base 11.
[0036] In operation, this invention works as follows: First, the fixed base 11 is installed in the designated position using bolts or other connecting parts through the mounting holes 37 at the four corners of the upper surface of the fixed base 11, providing stable support for the entire device. Then, the electric heater body 20 is placed in the center of the upper surface of the fixed base 11. The bidirectional synchronous motor 13 is started, and its two output ends drive the adjusting screw 14 to rotate synchronously. Since the adjusting screw 14 is threadedly connected to the adjusting screw hole 17 on the clamping arm 16, and the clamping arm 16 slides within the sliding groove 15, when the adjusting screw 14 rotates, the two clamping arms 16 will slide along the sliding groove 15. The slots 15 move closer or further apart. When the two clamping arms 16 move closer together, they drive the two clamping plates 18 and the two first anti-slip pads 19 closer to both sides of the electric heater body 20, until the two first anti-slip pads 19 are tightly attached to both sides of the electric heater body 20, thus initially clamping and fixing it. Rotating the first knob 35 drives the first limiting screw 23 to rotate within the first limiting screw hole 22, thereby adjusting the height of the U-shaped limiting frame 24, so that the second anti-slip pad 25 is tightly attached to one side of the upper surface of the electric heater body 20, providing top limiting for the electric heater body 20. Positioning function: Based on the position of the heat dissipation fins 30 of the electric heater body 20, rotating the second knob 36 drives the second limiting screw 27 to rotate within the second limiting screw hole 26, adjusting the position of the limiting plate 28 and the elastic protective pad 29, so that the elastic protective pad 29 tightly fits the side of the heat dissipation fins 30 away from it, achieving further limiting and protection of the side of the electric heater body 20, preventing it from swaying back and forth; during the operation of the electric heater body 20, the first anti-slip pad 19, the second anti-slip pad 25, and the elastic protective pad 29 can increase the friction force and prevent the electric heater body from swaying back and forth. Due to vibration, the electric heater body 20 is displaced. At the same time, the various limiting structures, as well as the fixing seat 11, clamping arm 16 and other components work together to ensure that the electric heater body 20 is stably installed and maintains a good heating effect. When the electric heater body 20 needs to be maintained or replaced, turn the first knob 35 and the second knob 36 in the opposite direction to move the U-shaped limiting frame 24 and the elastic protective pad 29 away from the electric heater body 20. Then, start the bidirectional synchronous motor 13 to reverse, which will drive the two clamping arms 16 to move away from each other, release the clamp on the electric heater body 20, and then the electric heater body 20 can be taken out.
[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
