DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] See also Figure 1-6 In the present embodiment, a device for heat treatment of galvanized steel without crystallization of optical fiber cable is provided, comprising a tubular furnace 1 and a base 4. The four corners of the bottom of the tubular furnace 1 are respectively fixedly connected to the top of the base 4. How to operate and use the tubular furnace 1 is already the prior art and will not be elaborated on in detail. The model is selected according to the use requirements. Brackets 5 are respectively attached to the left and right sides of the front of the tubular furnace 1, and the inner front of the bracket 5 is connected to a heat dissipation structure 2. The bottom of the heat dissipation structure 2 is connected to a groove plate 7, and the inner wall of the groove plate 7 is connected to a support structure 3. The outer wall of the bracket 5 is threadedly connected to a first bolt 6, and a handle 8 is connected to the right side of the support structure 3.

[0023] The heat dissipation structure 2 includes a shell 201 and a straight rod 202. The rear of the outer wall of the shell 201 is fixedly connected to the inner front of the bracket 5. The left and right sides of the inner wall of the shell 201 are respectively connected to the left and right sides of the outer wall of the straight rod 202 for rotation. The straight rod 202 is rotated by bearings on the left and right sides of the inner wall of the shell 201. The outer wall of the straight rod 202 is fixedly connected to a cylinder 203. The left and right sides of the shell 201 are respectively processed with through openings 204. The front and back sides of the inner wall of the shell 201 are respectively provided with square plates 205. The outer wall of the square plate 205 located in the front is plugged into the front end of the inner wall of the shell 201. The front square plate 205 can be separated from the inner wall of the shell 201 by moving forward. The outer wall of the square plate 205 located in the rear is fixedly connected to the rear of the inner wall of the shell 201.

[0024] Through the heat dissipation structure 2, the galvanized steel of the optical fiber cable will contact the cylinder 203. As the galvanized steel of the optical fiber cable is continuously transported forward, the cylinder 203 is forced to rotate through the straight rod 202. At the same time, through holes 204 are provided on both sides of the outer shell 201 for ventilation and heat dissipation, thereby preventing the heated galvanized steel of the optical fiber cable from being exposed to air and rapidly cooled, thereby achieving crystallization-free processing of the galvanized steel of the optical fiber cable. Then, the galvanized steel of the optical fiber cable will be discharged from the inner wall of the square plate 205 in the front, thereby achieving buffered heat dissipation, ensuring the normal use of the heat treatment device, and eliminating the use limitations of the heat treatment device.

[0025] The rear of the outer wall of the first bolt 6 is threadedly connected to the front face of the tube furnace 1. The first bolt 6 fixes the bracket 5 and the tube furnace 1. The supporting structure 3 includes a convex plate 301 and a screw rod 302. The upper part of the outer wall of the convex plate 301 is plugged into the inner wall of the groove plate 7. The bottom of the convex plate 301 is fixedly connected to the top of the screw rod 302. The outer wall of the screw rod 302 is threadedly connected with a vertical cylinder 303. The vertical cylinder 303 is rotated up and down on the outer wall of the screw rod 302 under force. The bottom of the vertical cylinder 303 is fixedly connected with a bottom plate 304, and the bottom plate 304 is a rubber plate. The right side of the vertical cylinder 303 is fixedly connected to the left side of the handle 8, and the handle 8 is convenient for driving the vertical cylinder 303 to rotate.

[0026] Working principle:

[0027] Heat treatment equipment installation:

[0028] The inner wall of the rear square plate 205 of the shell 201 is plugged into the front socket of the tube furnace 1. At this time, the rear of the bracket 5 is in contact with the front of the tube furnace 1. Then the first bolt 6 is threaded through the bracket 5 from the right front to the rear and fixed with the tube furnace 1. Then the outer wall of the convex plate 301 is plugged into the inner wall of the groove plate 7. Then, the handle 8 is used to rotate the vertical cylinder 303 downward on the outer wall of the screw rod 302. The rotating vertical cylinder 303 moves the bottom plate 304 downward, so that the bottom of the bottom plate 304 is pressed against the ground, and the installation of the heat treatment device is completed.

[0029] Heat treatment equipment use:

[0030] The galvanized steel of the optical fiber cable is inserted at the rear of the tubular furnace 1. The tubular furnace 1 works to transport the galvanized steel of the optical fiber cable forward while heating it. Then the galvanized steel of the optical fiber cable is discharged from the front outlet of the tubular furnace 1 and enters the outer shell 201 through the rear square plate 205. The galvanized steel of the optical fiber cable will contact the cylinder 203. Since the galvanized steel of the optical fiber cable is continuously transported forward, the cylinder 203 is forced to rotate through the straight rod 202. At the same time, through holes 204 are provided on both sides of the outer shell 201 for ventilation and heat dissipation, so as to avoid the heated galvanized steel of the optical fiber cable from being exposed to air and rapidly cooled, so as to achieve the goal of no crystallization in the processing of the galvanized steel of the optical fiber cable. Then the galvanized steel of the optical fiber cable will be discharged from the inner wall of the square plate 205 in the front.

[0031] Embodiment 2:

[0032] See also Figure 1-6 : In this embodiment, a crystallization-free heat treatment device for galvanized steel of optical fiber cable also includes a bent plate 9 and a second bolt 10. The bottom of the rear end faces of the two bent plates 9 are respectively fixed to the upper left and right sides of the front square plate 205, and the top of the bent plate 9 is threadedly connected to the outer wall of the second bolt 10. The bottom of the outer wall of the second bolt 10 is threadedly connected to the top front of the outer shell 201.

[0033] Working principle:

[0034] When cleaning the inside of the shell 201, the second bolt 10 is rotated upward to disengage from the top of the shell 201, and then the bent plate 9 is pushed forward. The bent plate 9 is forced to move the front square plate 205 forward to disengage from the shell 201, and then the inside of the shell 201 can be cleaned.
