[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a bolt-free quick-install end cover generator, including a casing 1, which is the main shell of the generator, used to fix and protect the internal mechanical structure and power generation components. The bottom surface of the casing 1 is fixedly connected with two groups of symmetrically arranged brackets 11, and the bottom end of the bracket 11 is fixedly connected with a base 12. The bracket 11 and the base 12 are used to support and stabilize the structure of the generator to enhance the overall stability and supporting capacity. The end of the casing 1 is fixedly connected with a positioning ring 2, the inner diameter of the positioning ring 2 is smaller than the inner diameter of the casing 1, and the positioning ring 2 forms an edge protruding inward at the end of the casing 1, which is used to position and fix the cover 3. The inner ring wall of the positioning ring 2 is provided with four groups of symmetrically arranged and distributed card grooves 21. The card grooves 21 are used to cooperate with the fixing components 4 on the cover 3 to realize the positioning of the cover 3 and prevent the cover 3 from rotating. The side wall of the positioning ring 2 is provided with a cover 3, which is used to support the output shaft of the generator and protect the internal parts of the generator.

[0029] Reference Figure 3 - Figure 4The side wall of the cover 3 is provided with a fixing assembly 4, which is used to realize a quick connection between the cover 3 and the housing 1, thereby improving the installation efficiency. The fixing assembly 4 includes a mounting groove 41, which is provided on the side wall of the cover 3. The mounting groove 41 is a slotted structure on the side wall of the cover 3, which is used to accommodate a positioning plate 42 and provide a track for the positioning plate 42 to move. The interior of the mounting groove 41 is slidably connected with a positioning plate 42, which is plugged into the interior of the card slot 21. The positioning plate 42 corresponds to the position of the card slot 21. When plugged into the card slot 21, the rotation direction of the cover 3 is fixed. The side wall of the positioning plate 42 is fixedly connected with a protrusion 43, which fits the side wall of the positioning ring 2, and the bottom of the protrusion 43 is set to an inclined shape. The protrusion 43 forms a convex portion on the side wall of the positioning plate 42, thereby being stuck together with the side wall of the positioning ring 2, thereby fixing the positioning ring 2 and the cover 3 together to prevent the cover 3 from falling off. A guide rod 44 is fixedly connected inside the installation groove 41, and the guide rod 44 penetrates and is slidably connected to the side wall of the positioning plate 42. The guide rod 44 is used to guide the positioning plate 42 so that the positioning plate 42 can stably move inside the installation groove 41. The positioning plate 42 is elastically connected to the inner wall of the installation groove 41 through a return spring 45. The return spring 45 is used to provide stable elastic support for the positioning plate 42 so that the positioning plate 42 and the card slot 21 maintain a plug-in relationship. After the inclined surface at the bottom of the protrusion 43 is squeezed with the inside of the card slot 21, it can quickly return to its original position, so that the protrusion 43 passes from one side of the positioning ring 2 and is engaged with the other side of the positioning ring 2.

[0030] Reference Figure 3 - Figure 4 , four groups of mounting grooves 41 and positioning plates 42 are provided. Multiple groups of mounting grooves 41 and positioning plates 42 ensure that all parts of the cover 3 can be evenly supported and fixed. The tops of the four groups of positioning plates 42 are fixedly connected with hinge seats 46. The inner wall of the hinge seats 46 is hinged with traction rods 47. The ends of the traction rods 47 are hinged with rings 48. The traction rods 47 are used to connect the positioning plates 42 and the rings 48 together. The four groups of positioning plates 42 are linked together through the rings 48, so that the four groups of positioning plates 42 are moved toward the center of the cover 3 by moving the rings 48 and transmitting to the positioning plates 42 through the traction rods 47, thereby releasing the limit on the cover 3 and facilitating the removal of the cover 3. Two groups of symmetrically arranged handles 49 are fixedly connected to the surface of the rings 48. The handles 49 are used for the staff to pull the rings 48.

[0031] Working principle: First, the staff member holds the handle 49 and pulls the ring 48 outward. The movement of the ring 48 is transmitted to the positioning plate 42 through the traction rod 47, causing the four groups of positioning plates 42 to move toward the center of the cover 3 at the same time. At this time, the positioning plates 42 gradually disengage from the slots 21, and the protrusions 43 are misaligned with the positioning ring 2, releasing the limit on the cover 3. The reset spring 45 begins to work, but due to the pulling force of the traction rod 47, the positioning plates 42 will not return to their original positions immediately. The staff member can continue to pull the ring 48 outward until all the positioning plates 42 are completely out of the slots 21. At this time, the fixing relationship between the cover 3 and the casing 1 is released, and the cover 3 can be freely removed.

[0032] After removing the cover 3, the staff can conveniently maintain or inspect the inside of the generator. When the work is completed, put the cover 3 back to its original position and then release the ring 48. At this time, the elastic force of the return spring 45 will push the positioning plate 42 to move in the direction of the slot 21 until the positioning plate 42 is plugged into the slot 21 again, and the protrusion 43 fits with the inside of the positioning ring 2, thereby completing the fixing of the cover 3.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
