Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a connecting block, a component, and its arm, such as Figures 1 to 6 As shown.

[0026] Example 1: A connecting block includes a first insert 1 and a second insert 2. The first insert 1 has a slot 3 at one end near the second insert 2, and a fixing plate 4 is fixedly installed at one end of the second insert 2 near the first insert 1. The fixing plate 4 and the slot 3 are inserted into each other. Both the first insert 1 and the second insert 2 have a snap-fit ​​part. The first insert 1 and the second insert 2 are snap-fitted into the arm body 11 through the snap-fit ​​part, so that the first insert 1 and the second insert 2 can be stably connected to the arm body 11.

[0027] The snap-fit ​​part includes two horizontal snap-fit ​​strips 5 and two vertical snap-fit ​​strips 6. The two horizontal snap-fit ​​strips 5 are fixedly installed on the upper and lower sides of the first insert 1 near the end of the second insert 2, and the two vertical snap-fit ​​strips 6 are fixedly connected to the two ends of the fixing plate 4 near the bottom side wall of the slot 3.

[0028] Both the horizontal locking strip 5 and the vertical locking strip 6 have triangular cross-sections, with their tips pointing away from the center of the first insert block 1, which facilitates disassembly and assembly work for the staff.

[0029] The first insert 1 is equipped with a connecting part for connecting with the second insert 2. The connecting part includes a locking block 7 and a locking groove 8. The locking block 7 is fixedly connected to the bottom side wall of the slot 3, and the locking groove 8 is provided on the fixing plate 4. When the fixing plate 4 is inserted into the interior of the slot 3, the locking block 7 and the locking groove 8 engage with each other.

[0030] When the fixing plate 4 is inserted into the slot 3, the fixing plate 4 can limit the position of the horizontal locking strip 5 on the first insertion block 1, so that it can be stably locked with the arm body 11. When the locking block 7 is locked with the slot 8, the locking block 7 can limit the position of the vertical locking strip 6 on the fixing plate 4, so that it can be stably locked with the arm body 11.

[0031] The shape of the card block 7 is trapezoidal, with one end near the bottom side wall of the card slot 8 being the short side. The short side is folded to both ends to form a convex strip. The convex strip is interference-fitted with the groove provided on the wall of the card slot 8, which can stably connect the first insert block 1 and the second insert block 2 together.

[0032] The locking block 7 is provided with a relief groove 9. When the protrusion is squeezed by the groove wall of the locking groove 8, the distance between the two sides of the relief groove 9 will be reduced, so that the protrusion can be smoothly engaged with the groove on the groove wall of the locking groove 8. A spring piece is fixedly installed between the two sides of the relief groove 9. The spring piece 10 is U-shaped, and its two ends of the open end are fixedly connected to the two sides of the relief groove 9. The opening of the spring piece 10 faces downward. A fixing rod 15 is fixedly installed at the closed end of the spring piece 10. The spring piece 10 has the elastic force to push the two sides of the relief groove 9 to the sides, so that the locking block 7 and the locking groove 8 can be stably engaged together.

[0033] Example 2: An assembly includes the aforementioned connecting block and a push rod 16. The diameter of the push rod 16 is adapted to the diameter of the fixing rod 15. The push rod 16 is slidably mounted on the arm body 11. When disassembly is required, a clamping force is applied to the push rod 16 in the direction of the fixing rod 15, thereby causing the fixing rod 15 to press against the spring piece 10. Subsequently, the two ends of the open end of the spring piece 10 pull the two side walls of the relief groove 9, causing the protrusion to disengage from the groove on the groove wall of the slot 8. At this time, the fixing plate 4 can be removed from the inside of the slot 3, that is, the second insert 2 can be removed from the arm body 11, and then the arm body 11 can be separated from the first insert 1.

[0034] Example 3: An arm includes an arm body 11, and also includes the aforementioned connecting block and components. The arm body 11 is provided with a socket 12 adapted to the first plug 1 and the second plug 2. The first plug 1 is fixedly installed on the fuselage of the drone, and the second plug 2 is fixedly installed on the rotor blade of the drone. During installation, the arm body 11 is inserted into the first plug 1, and then the second plug 2 is inserted into the socket 12.

[0035] The inner wall of the socket 12 is provided with a latch 13 that is compatible with the horizontal latch 5 and the vertical latch 6. When the fixing plate 4 is inserted into the slot 3, the fixing plate 4 can make the horizontal latch 5 stably latched with the corresponding latch 13, and the latch block 7 can make the vertical latch 6 stably latched with the corresponding latch 13, so that the drone's rotor, arm body 11 and drone body can be stably connected together.

[0036] A countersunk groove 14 is provided on the lower side wall of the socket 12. The larger diameter end of the countersunk groove 14 is away from the socket 12. The push rod 16 is slidably installed inside the countersunk groove 14, and a circular plate is fixedly connected to the end of the push rod 16 located inside the larger end of the countersunk groove 14. A spring 17 is connected between the circular plate and the groove wall of the larger end of the countersunk groove 14. The spring 17 can keep the push rod 16 stable inside the countersunk groove 14 and prevent it from sliding at will. When it is necessary to disassemble the arm body 11, the push rod 16 can be pushed into the socket 12. At this time, the fixing rod 15 is subjected to the pressing force of the push rod 16, which will apply a pressing force to the spring piece 10, causing the open end of the spring piece 10 to pull the two side groove walls of the clearance groove 9, thereby causing the protrusion to disengage from the corresponding groove. At this time, the second insertion block 2 can be disengaged from the first insertion block 1. After the second insertion block 2 is disassembled, the arm body 11 can be separated from the first insertion block 1.

[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
