[0021] The following further describes the present utility model in detail with reference to the embodiments given in the accompanying drawings.
[0022] As Figures 1 to 6 shown, this embodiment provides a connecting member for a grinder hand rod. The connecting member 1 includes a first card set 2 and a second card set 3. Buckle assemblies 4 are connected to both sides of the first card set 2, and buckle portions 5 are provided on both sides of the second card set 3. The buckle assembly 4 can be locked with the buckle portion 5. The buckle assembly 4 includes a linkage member 41 and a buckle member 42. One end of the linkage member 41 is rotatably connected to the first card set 2, and the other end of the linkage member 41 is rotatably connected to the buckle member 42. The buckle member 42 includes a hand-pulling portion 421, a connecting portion 422, and a hook portion 423. The connecting portion 422 is rotatably connected to the linkage member 41, and the hook portion 423 can be locked with the buckle portion 5. Specifically, when the first card set 2 and the second card set 3 are connected together, pulling up the hand-pulling portion 421 can make the hook portion 423 and the buckle portion 5 in a unlocked state. When pressing down the hand-pulling portion 421 until the hand-pulling portion 421 is parallel to the first card set 2, the hook portion 423 and the buckle portion 5 are in a locked state.
[0023] As described above, a slot 21 is formed by inward depression at the center of the end of the first card set 2. A plug-in member 31 is provided at the end of the second card set 3 close to the slot 21. When the first card set 2 and the second card set 3 are connected, the plug-in member 31 is inserted into the slot 21. Such a structural design improves the strength when the hand rod is connected when the first card set 2 and the second card set 3 are inserted together.
[0024] As described above, the outer edge end face of the slot 21 is provided with a limiting hole 22 that is recessed inward. The end of the second card set 3 close to the slot 21 is also provided with a limiting member 32. At the same time, the limiting member 32 is inserted into the limiting hole 22 to form a limiting structure. Specifically, there are two limiting holes 22, and correspondingly, there are also two limiting members 32. Such a structural design enables the first card set 2 and the second card set 3 to quickly align the buckle assembly 4 with the buckle portion 5 and achieve locking when locking.
[0025] As described above, two first hinge ears 23 are oppositely arranged on both sides of the first card set 2. First mounting holes 231 are opened on both of the two first hinge ears 23. One end of the linkage member 41 is provided with a first through hole 411. A first pin shaft 412 is inserted through the first through hole 411. Both ends of the first pin shaft 412 are embedded in the corresponding first mounting holes 231. The linkage member 41 is hinged to the first hinge ear 23 through the first pin shaft 412.
[0026] As described above, the other end of the linkage member 41 is provided with a second through hole 413. Two second hinge ears 424 that extend downward and are oppositely arranged are provided on the connecting portion 422. Second mounting holes 425 are provided on both of the two second hinge ears 424. A second pin shaft 426 is inserted through the second through hole 413. Both ends of the second pin shaft 426 are embedded in the corresponding second mounting holes 425. The linkage member 41 is hinged to the second hinge ear 424 through the second pin shaft 426.
[0027] As described above, two vertical blocks 33 that are oppositely arranged and extend outward are provided on both sides of the second card set 3. Third mounting holes 331 are provided on both of the two vertical blocks 33. A hook member 332 is provided between the two vertical blocks 331. Both ends of the hook member 332 are fixedly installed in the corresponding third mounting holes 331. The hook portion 423 of the card is hooked on the hook member 332 and can form a locking structure therewith.
[0028] As described above, the interiors of both the first card set 2 and the second card set 3 are hollow structures. Ring-shaped stop protrusions 6 are provided inside both the first card set 2 and the second card set 3. A hand rod 7 can be inserted into both the first card set 2 and the second card set 3. The ring-shaped stop protrusion 6 can stop the hand rod 7.
[0029] As described above, a dust-proof sealing ring 8 is clamped between the first card set 2 and the second card set 3, which can prevent dust from entering the hand rod 7. Specifically, the dust-proof sealing ring 8 is sleeved on the plug-in member 31.
[0030] In summary, when it is necessary to latch the first card kit 2 and the second card kit 3, the plug-in member 31 and the limiting member 32 on the second card kit 3 can be inserted into the slot 21 and the limiting hole 22 on the first card kit 2 respectively, and then the manual bending part 421 is bent upward and pushed forward so that the hook part 423 can be hooked with the hanging part 332. After the hook part 423 is hooked with the hanging part 332, the manual bending part 421 is pulled backward and pressed downward until it is parallel to the first card kit 2, and then the buckle assembly 4 is latched with the buckle part 5. Conversely, the first card kit 2 and the second card kit 3 in the connected state can be unlocked and disassembled.
[0031] The above are only the preferred embodiments of the present invention, and the scope of implementation of the present invention cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the description content of the utility model still fall within the scope covered by the patent of the present invention.
