[0040] The connecting rod 12 is fixedly installed on the lower end surface of the transmission disk 11, and the outer side of the connecting rod 12 is connected to a first connecting plate 13 installed on the lower end of the inside of the box body 1, a first adjusting plate 14 is fixedly installed on the left side of the first connecting plate 13, and a first fixing plate 15 is arranged on the outer side of the upper end of the first adjusting plate 14, a rope 16 is arranged on the right end surface of the first adjusting plate 14, and the outer end of the rope 16 is connected to a guide wheel 17 installed on the right end of the inside of the box body 1, and the right end of the rope 16 is connected to an adjusting component 18, a second fixing plate 19 is fixedly installed on the upper end surface of the adjusting component 18, and the outer side of the left end of the second fixing plate 19 is connected to a film capacitor body 20 located on the outer side of the right end of the first fixing plate 15, a movable rod 21 is arranged through the middle of the upper mounting plate 5, and The front and rear ends of the movable rod 21 are respectively fixed with fixed blocks 22, and the outer side of the fixed block 22 is connected to a movable groove 23 opened on the inner side of the upper mounting plate 5, the outer side of the lower end of the movable rod 21 is connected to a second connecting plate 24 located inside the box body 1 through a bearing, and a connecting block 25 is installed on the lower end surface of the second connecting plate 24, and an upper fixing frame 26 connected to the film capacitor body 20 is arranged on the outer side of the lower end of the connecting block 25. At the same time, a second spring 27 is installed inside the lower end of the upper mounting plate 5 through a prefabricated groove and is located on the outer side of the upper end of the second connecting plate 24. A placing table 29 is fitted in the middle of the inner side of the box body 1, and a heat dissipation hole 30 is opened through the left wall end of the box body 1, which is combined to form a fixing mechanism for film capacitor production with an anti-loosening structure.

[0041] When using the fixing mechanism for producing film capacitors with an anti-loosening structure, the specific Figure 1 , Figure 4 and Figure 6 As shown, firstly, the whole is stably placed on the designated plane through the mounting base 2, then the upper cover 3 installed by the hinge on the outer side of the upper end of the box body 1 is opened, and the film capacitor body 20 to be fixed is placed on the upper end surface of the placement table 29, and then the driving motor 9 arranged on the inner side of the protective cover 8 is opened, so that the driving motor 9 drives the transmission rod 10, the transmission disk 11 and the connecting rod 12 to rotate inside the lower end of the box body 1. Since the connecting rod 12 is connected to the first connecting plate 13 in a sliding manner, and a through groove structure matching the connecting rod 12 is provided inside the left end of the first connecting plate 13, the connecting rod 12 is connected to the first connecting plate 13 in a rotational sliding manner while rotating, so that the transmission disk 11 and the connecting rod 12 can drive the first connecting plate 13 and the first adjusting plate 14 to perform horizontal reciprocating motion inside the left end of the box body 1. When the first adjusting plate 14 moves to the rightmost end, the first fixing plate 15 contacts the left end surface of the film capacitor body 20.

[0042] Since the second adjustment plate 1801 is installed on the right side of the inner end of the box body 1, the limiting plate 1802 is fixedly installed on the lower end surface of the second adjustment plate 1801 and contacts with the box body 1, the first spring 1803 is arranged inside the lower wall end of the box body 1, and the hook 1804 is respectively fixedly installed on the right end surfaces of the second adjustment plate 1801 and the first adjustment plate 14, and the limiting plate 1802 forms a telescopic structure with the box body 1 through the first spring 1803, and the second adjustment plate 1801 installed above the limiting plate 1802 is arranged parallel to the first adjustment plate 14. When the first adjustment plate 14 moves to the right, the rope 16 pulled by the hook 1804 at the left end of the first adjustment plate 14 moves outside the guide wheel 17, causing the guide wheel 17 to rotate, so that the guide wheel 17 guides and supports the rope 16. At this time, the first spring 1803 in the compressed state recovers its deformation, causing the second adjustment plate 1801, the limit plate 1802 and the second fixing plate 19 to move to the left inside the box 1, so that the second fixing plate 19 contacts the right end surface of the film capacitor body 20, and the second fixing plate 19 contacts the right end surface of the film capacitor body 20. Figure 3 As shown, the first fixing plate 15 and the second fixing plate 19 are connected to the box body 1 in a sliding manner, and the upper end cross-sections of the first fixing plate 15 and the second fixing plate 19 are both arc-shaped, so that the first fixing plate 15 and the second fixing plate 19 play a role in clamping and fixing the film capacitor body 20;

[0043] Similarly, when the first adjustment plate 14 moves to the left, the second adjustment plate 1801 moves to the right under the action of the rope 16 and the hook 1804, so that the first fixing plate 15 and the second fixing plate 19 are separated from the film capacitor body 20 respectively, thereby releasing the fixing effect on the film capacitor body 20, making the overall use convenient.

[0044] Specific as Figure 1 , Figure 2 and Figure 7 As shown, after the film capacitor body 20 is firmly placed in the box body 1 through the first fixing plate 15 and the second fixing plate 19, the upper cover 3 is closed and locked by the box lock body 4. Since the mounting base 2 is connected to the upper mounting plate 5 by plugging, and the mounting base 2 is connected to the magnetic block 7 by magnetic attraction, and the longitudinal section of the support frame 6 installed on the outside of the magnetic block 7 is "L"-shaped, when it is necessary to combine and stack the box body 1 with the film capacitor body 20, the mounting base 2 can be inserted into the upper mounting plate 5. At this time, the lower end of the mounting base 2 is located inside the support frame 6, and the mounting base 2 is magnetically connected to the magnetic block 7 installed inside the support frame 6, so that the mounting base 2 can be firmly placed on the upper end of the upper cover 3, so that the whole has a better combination and stacking function, which is convenient for later handling or transportation;

[0045] Since the longitudinal section of the movable rod 21 is a "T" shape, the movable rod 21 forms a telescopic structure with the upper mounting plate 5 through the second spring 27, and the upper fixing frame 26 is arranged symmetrically with respect to the vertical center axis of the film capacitor body 20 and plays a supporting and fixing role for the upper edge of the film capacitor body 20. When the box body 1 is superimposed and installed on the outer side of the upper end of the upper top cover 3 under the action of the mounting base 2, the lower end surface of the mounting base 2 is connected to the upper end of the movable rod 21. At this time, the movable rod 21 slides downward under the gravity of the mounting base 2, so that the second connecting plate 24 and the connecting block 2 5 and the upper fixing frame 26 both slide downward inside the box body 1, and the second spring 27 is stretched and deformed, so that the upper fixing frame 26 and the edges of both sides of the upper end of the film capacitor body 20 are connected to each other, so that the upper fixing frame 26 further fixes the film capacitor body 20, thereby improving the anti-loosening effect of the film capacitor body 20. When the mounting base 2 is disassembled and separated from the upper mounting plate 5, the movable rod 21 moves upward under the action of the rebound force generated by the second spring 27, and the upper fixing frame 26 is disconnected from the film capacitor body 20;

[0046] Specific as Figure 2 , Figure 5 and Figure 8 As shown, since the fixed block 22 is connected to the upper mounting plate 5 in a sliding manner through the movable groove 23, and the cross section of the movable groove 23 is an arc shape, and the fixed block 22 is symmetrically arranged front and back about the vertical center axis of the movable rod 21, when the uppermost box 1 is no longer stacked, the movable rod 21 is pressed downward to repeat the above operation steps for the second connecting plate 24, the connecting block 25, the upper fixing frame 26 and the second spring 27. When the movable rod 21 moves downward to the lowest point, the movable rod 21 is rotated counterclockwise to rotate the movable rod 21 at the upper end of the second connecting plate 24 through the bearing. At this time, the fixed block 22 is slidably connected to the upper mounting plate 5 through the movable groove 23. After rotating a certain angle, the fixed block 22 is located inside the upper mounting plate 5 and It plays a fixing role on the movable rod 21, and then the upper fixing frame 26 can be connected to the film capacitor body 20 and play a fixing role. When the upper fixing frame 26 needs to be separated from the film capacitor body 20, the movable rod 21 can be rotated in the opposite direction. When the movable rod 21 is rotated in the opposite direction to the specified position, the movable rod 21 moves upward under the action of the rebound force generated by the second spring 27, and the upper fixing frame 26 is disconnected from the film capacitor body 20. Rubber pads are provided at the connection between the first fixing plate 15, the second fixing plate 19 and the upper fixing frame 26 and the film capacitor body 20. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
