[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example: Figure 1-4 As shown, the utility model provides a technical solution, a pressure control device of a flat vulcanizing machine for producing lightning arresters, including a booster plate 1, a connecting plate 2 and an upper heating plate 3. The booster plate 1 is equidistantly slidably connected with four connecting pieces inside, and one end of the four connecting pieces is evenly provided with a stopper. The other end of the connecting piece passes through the booster plate 1 and is fittedly connected with the connecting plate 2. A positioning rod 5 is movably inserted in the middle of the connecting piece, and one end of the positioning rod 5 is fixedly connected to the stopper. The other end of the positioning rod 5 passes through the connecting piece and the booster plate 1 and is fixedly connected to the connecting plate 2. A handle is welded in the middle of the top of the stopper 6. A through groove for accommodating the positioning rod 5 is provided inside the connecting plate 2. A positioning groove and a circular movable groove are provided below the through groove in sequence. The positioning groove and the through groove are in a cross shape. The lower end of the positioning rod 5 passes through the through groove and extends into the circular movable groove to be fixedly connected to a limited position block. The limit block is clamped in the positioning groove. A groove is provided at the bottom of the limit block. A magnet A is fixedly provided inside the groove. A magnet B of the same name matching the magnet A is provided in the circular movable groove. The bottom end of the connecting plate 2 is fixedly connected to the upper heating plate 3. A distance scale 4 penetrating the booster plate 1 is embedded in the middle of the top end of the connecting plate 2;

[0029] The top of the connecting plate 2 is symmetrically embedded with a spacing positioning structure 7, which includes a positioning block 71, a pulley 72, a rotating column 73, a screw rod 74, a moving block 75, a top plate 76, a moving bar 77 and a connecting belt 78;

[0030] The top of the connecting plate 2 is symmetrically embedded with positioning blocks 71 on both sides, and a rotating column 73 is rotatably connected inside the positioning block 71. A pulley 72 that fits the top of the connecting plate 2 is welded to the bottom of the rotating column 73. A screw rod 74 is welded to the top of the rotating column 73, and the screw rod 74 is located inside the positioning block 71 and is rotatably connected to the positioning block 71. The outer surface of the screw rod 74 is connected to a moving block 75 through a thread. The moving block 75 is slidably connected to the inside of the positioning block 71, and the positioning block 71 has a bottom position for the moving block 75. The movable block 75 is matched with the groove, and a top plate 76 is welded in the middle of the top end. The screw rod 74 is used to change the distance between the top end of the top plate 76 and the bottom end of the connecting plate 2. The top plate 76 is symmetrically slidably connected with a moving bar 77. A connecting belt 78 is sleeved between the two pulleys 72. The connecting belt 78 is used for the synchronous rotation between the two pulleys 72, and is used to change the distance between the top end of the top plate 76 and the bottom end of the booster plate 1, so as to adjust the active spacing between the booster plate 1 and the connecting plate 2, so as to adjust the pressure between the connecting plate 2, the protective cover and the lightning arrester.

[0031] A limiting structure 8 is equidistantly installed at the top of the booster plate 1, and the limiting structure 8 includes a limiting plate 81, a screw rod 82, a concave rod 83, a hinge 84 and a concave strip 85;

[0032] A limit plate 81 is equidistantly installed at the top of the booster plate 1. One end of the limit plate 81 is rotatably connected to a screw rod 82. The outer surface of the screw rod 82 is located inside the limit plate 81 and is threadedly connected to a concave rod 83. The rotation of the screw 82 can drive the concave rod 83 to move horizontally left and right along the inside of the limit plate 81. The concave rod 83 is slidably connected to the inside of the limit plate 81, and a guide groove corresponding to the sliding of the concave rod 83 is opened inside the limit plate 81. A hinge 84 is installed at the top of the limit plate 81 by screws. One end of the hinge 84 is installed by screws There is a concave strip 85, which is rotated 180° along the top edge of the limiting plate 81 through a hinge 84. At this time, the concave strip 85 is separated from the handle 6. When one end surface of the concave strip 85 and one end surface of the limiting plate 81 are in contact with each other, the concave strip 85 enters the outside of the handle 6 to limit the handle 6. A rectangular groove is provided inside the concave strip 85 at a position corresponding to one end of the concave rod 83. When the concave rod 83 moves left and right, it enters the inside of the concave strip 85 to position the concave strip 85.

[0033] The working principle and use process of the utility model: during the actual use of the device, the user connects the booster plate 1, the connecting plate 2, the upper heating plate 3, the positioning rod 5 and the handle 6. Since the handle 6 vibrates slightly due to the operation of the machine after installation, the user rotates the concave bar 85 at this time, and the concave bar 85 rotates along one end of the limit plate 81 through the hinge 84. Then the user rotates the screw 82, and the screw 82 drives the concave rod 83 to enter the concave bar 85 when rotating, so as to achieve the purpose of fixing the concave bar 85, thereby achieving the purpose of fixing the handle 6 by using the concave bar 85, preventing the handle 6 from deflecting due to the vibration caused by long-term use of the machine, thereby increasing the overall stability and safety of the device and facilitating the safe use of the device.

[0034] The personnel then pulls the moving bar 77, which slides along the inside of the top plate 76. Then the personnel pulls the connecting belt 78, and the connecting belt 78 drives the pulley 72 to rotate when it is displaced. When the pulley 72 rotates, it drives the screw rod 74 to rotate through the rotating column 73. When the screw rod 74 rotates, it drives the moving block 75 and the top plate 76 to rise under the action of the positioning block 71. At this time, the distance between the top of the top plate 76 and the bottom of the booster plate 1 is changed. Because the booster plate 1 drives the spring to compress when it moves downward and causes the distance between the booster plate 1 and the connecting plate 2 to change relatively, at this time, due to the action of the top of the connecting plate 2, the distance between the booster plate 1 and the connecting plate 2 cannot be changed, thereby causing the upper heating plate 3 at the bottom of the connecting plate 2 to keep the pressure between the protective cover and the lightning arrester consistent, thereby ensuring that the pressure between the protective cover and the lightning arrester remains constant, which is beneficial to the molding between the protective cover and the lightning arrester, thereby improving the qualified rate of the lightning arrester.

[0035] Finally, it should be noted that the above description is only a preferred example of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
