Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0018] The capacitor 1 (model 400V4700UF), capacitor guide pin 2 (model ARITERCH115) and synchronous sprocket A4 (model T5) mentioned in the utility model can all be purchased from the market or obtained through private customization.
[0019] See also Figures 1 to 3 The utility model provides an embodiment: a high-strength capacitor guide pin, including a capacitor 1, a capacitor guide pin 2 is provided on both sides of the upper end surface of the capacitor 1, a fixing cover 3 is provided above the capacitor 1, and both sides of the inside of the fixing cover 3 are provided with an external thread reinforcement sleeve A13 threadedly connected thereto, the two external thread reinforcement sleeves A13 are respectively located on the outsides of the two capacitor guide pins 2, an internal thread through hole 14 penetrating the external thread reinforcement sleeve A13 is provided in the middle position of the upper end surface of the external thread reinforcement sleeve A13, an external thread reinforcement sleeve B15 matching its internal thread is provided inside the internal thread through hole 14, and the inner wall of the external thread reinforcement sleeve B15 is in contact with the outer surface of the capacitor guide pin 2.
[0020] A rubber fixing rod is fixedly provided at each of the four end corners of the outer surface of the fixing cover 3 ; when in use, the fixing cover 3 is fixed to the upper end surface of the capacitor 1 through the rubber fixing rod.
[0021] A synchronous rotating shaft 5 is provided in the middle position inside the fixed cover 3, a manual rotating head is provided in the middle position of the upper end surface of the synchronous rotating shaft 5, a square slot 6 is provided in the middle position of the upper end surface of the manual rotating head, a square fixing rod 7 is inserted into the inside of the square slot 6, the inner wall cross-section of the square slot 6 is square, and the outer surface of the square fixing rod 7 is in contact with the inner wall of the square slot 6, a locking cover 8 is fixedly provided on the upper end surface of the square fixing rod 7, a locking rod 9 is fixedly provided on the four end corners of the lower end surface of the locking cover 8, and a locking slot 10 located on the upper end surface of the fixed cover 3 is provided on the outer side of the locking rod 9; when the square fixing rod 7 is inserted into the inside of the square slot 6, the synchronous rotating shaft 5 itself cannot rotate, and when it is necessary to move the external thread reinforcement sleeve B15 and the external thread reinforcement sleeve A13 upward to cover the outer surface of the capacitor guide pin 2, grab the locking cover 8, and then take it off from the upper end surface of the fixed cover 3, and when the square fixing rod 7 is completely pulled out from the inside of the square slot 6, the synchronous rotating shaft 5 can be manually rotated.
[0022] A synchronous sprocket A4 is fixedly sleeved on the lower side of the outer surface of the synchronous shaft 5, and a synchronous sprocket B11 is provided on the front and rear sides of the synchronous sprocket A4. The two synchronous sprockets B11 are connected in series with one synchronous sprocket A4 via a synchronous chain 17. When the synchronous shaft 5 rotates, the synchronous sprocket A4 fixedly sleeved on the lower side of the outer surface of the synchronous shaft 5 and the two synchronous sprockets B11 connected in series with the synchronous sprocket A4 via the synchronous chain 17 will rotate synchronously therewith.
[0023] A long rod 12 is fixedly provided on both sides of the upper end surface of the synchronous sprocket B11, and the two long rods 12 are movably inserted into the interior of the external thread reinforcement sleeve A13 located above it; when the synchronous sprocket B11 rotates, the two long rods 12 located on its upper end surface will also rotate accordingly. Since the long rods 12 are movably inserted into the interior of the external thread reinforcement sleeve A13, when the long rods 12 are driven to rotate by the synchronous sprocket B11, the external thread reinforcement sleeve A13 will be driven to rotate synchronously, and the external thread reinforcement sleeve A13 can move up and down through the transmission of the threaded structure.
[0024] One side of the long rod 12 is provided with an anti-rotation rod 16 which is vertically movable and passes through the externally threaded reinforcement sleeve B15. The lower end surface of the anti-rotation rod 16 is fixed to the fixing cover 3, and the upper fixing sleeve on the outer surface of the anti-rotation rod 16 is provided with a limiting sleeve. Since the lower end surface of the anti-rotation rod 16 which passes through the externally threaded reinforcement sleeve B15 is fixed to the fixing cover 3, the externally threaded reinforcement sleeve B15 itself cannot rotate. When the externally threaded reinforcement sleeve A13 rotates, the externally threaded reinforcement sleeve B15 which is threadedly connected to it through the internally threaded through hole 14 and cannot rotate by itself will move up and down under the transmission of the threaded structure. When the externally threaded reinforcement sleeve A13 moves upward, the externally threaded reinforcement sleeve B15 will also move upward accordingly. The threaded reinforcement sleeve A13 and the external threaded reinforcement sleeve B15 can cover the outer surface of the capacitor guide pin 2. The external threaded reinforcement sleeve B15 and the external threaded reinforcement sleeve A13 located on the outer surface of the capacitor guide pin 2 can replace the capacitor guide pin 2 to withstand mechanical stress. The external threaded reinforcement sleeve B15 that fits the outer surface of the capacitor guide pin 2 can prevent the capacitor guide pin 2 from bending. The strength of the capacitor guide pin 2 is improved by the above technical solution. At the same time, the external threaded reinforcement sleeve B15 and the external threaded reinforcement sleeve A13 can resist the influence of the external environment, such as temperature changes, humidity, etc., reduce corrosion and aging of the capacitor guide pin 2, and thus extend the service life of the capacitor guide pin 2.
[0025] When the threaded reinforcement sleeve A13 and the external threaded reinforcement sleeve B15 are moved to the corresponding positions, the square fixing rod 7 fixed to the locking cover 8 is inserted into the square slot 6, and the locking rod 9 located on the lower end surface of the locking cover 8 is inserted into the locking slot 10 to fix the synchronous rotating shaft 5 to prevent it from rotating without authorization, thereby causing the positions of the threaded reinforcement sleeve A13 and the external threaded reinforcement sleeve B15 to change.
[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
