detailed description

The following is a description of possible embodiments of the invention, but is not intended to limit the scope of the invention as claimed.

A preferred embodiment of the rotary detaching device 10 of the present invention, as shown in FIGS. 1 to 5, includes a base 20, a driving gear member 30, three driven teeth members 40, three clamping rods 50, and a turntable 60.

Referring to FIGS. 1 to 3B, the base 20 includes an upper clamp member 22 and a lower clamp member 24 which are combined with each other.

The driving gear member 30 is rotatably disposed on the base 20 (as shown in FIG. 3A), and the bottom end forms a gear end 32. The gear end 32 is clamped to the upper clamping member 22 and the lower portion of the base 20. Between the clips 24. Preferably, the base 20 is provided with a soft magnet 201 that abuts against an object 12. When the rotary disassembling device 1 is used, the flexible magnet 201 is interposed between the base 20 and the object 12. When the lid of the object 12 is made of a metal material, the adhesion can be increased. The rotary dismounting device 1 can be more stably positioned on the object 12 and has a slip-proof effect, and can be directly sucked by the magnetic cover after use.

Each of the driven tooth members 40 is rotatably disposed on the base 20. In detail, each of the driven tooth members 40 is axially disposed on the upper clamp member 22 and the lower clamp member 24 through a spindle. between. Each of the driven tooth members 40 may be made of elastic plastic or rubber, or may be made of a rigid material such as metal, and has a tooth portion 42 , and the tooth portion 42 is annularly disposed on the driven tooth member 40 . And engaging with the gear end 32 of the driving gear member 30, and each of the driven tooth members 40 is extended with an clamping rod 50 and can be rotated by the driving gear member 30. Preferably, each of the driven tooth members 40 is eccentrically provided with a connecting hole 44. The connecting hole 44 is disposed on the driven tooth member 40 in a manner offset from the rotating axis. In this embodiment, The driven tooth member 40 is elongated, and the tooth portion 42 and the connecting hole 44 are respectively disposed at two ends of the driven tooth member 40.

Each of the clamping rods 50 can also be made of elastic plastic or rubber and can be deformed by pressing, or can be made of a rigid material such as metal. Each of the clamping rods 50 can be integrally formed or assembled in multiple parts, and includes a clamping head 52, a neck portion 54, a large diameter section 541 and a clamping portion 56. The neck portion 54 is connected to the neck portion 54. The neck portion 54 of each of the clamping rods 50 is rotatably received in the connecting hole 44 of one of the driven tooth members 40. The clamping rod is disposed between the latching head 52 and the large diameter portion 541. The latching head 52 of the 50 and the clipping portion 56 are located outside the connecting hole 44 of the driven tooth member 40. In this embodiment, the clipping portion 56 is in the shape of a hexagonal column, but this is not In the limit, the pinch portion 56 may be in the shape of a column, a square column or other polygonal columns. The surface of the nip portion 56 may be provided with a rough structure formed, for example, with corundum, sandblasted structure or other processing means.

The turntable 60 is sleeved on the top end of the driving gear 30. In more detail, the driving gear member 30 is provided with a main shaft 31 from its axial center, the main shaft 31 protrudes from the upper clamping member 22, and the rotating plate 60 has a sleeve 601 at least partially sleeved on the main shaft 31. . Preferably, the main shaft 31 is in an extended and tapered shape, and the maximum radial dimension of the main shaft 31 is slightly larger than the radial dimension of the sleeve 601, so that the turntable 60 can be easily set and It can closely abut the main shaft 31. In the embodiment, the main shaft 31 is integrally extended by the driving gear, and the sleeve 601 completely covers the main shaft 31 so that it can have more contact faces. It can be understood that the main shaft 31 can also be detachably coupled to the driving gear 30. Combine.

Through the above structure, when the user needs to screw up the large-diameter screw-locking structure such as the oil filter or the pickles, please refer to FIG. 4, the user needs to first place the rotary dismounting device 10 on the object to be opened. 12, the top surface of the object 12 is abutted against the lower clip 24 of the base 20, and then the turntable 60 is rotated to drive the clips via the active tooth member 30 and the driven tooth members 40. 50 swinging, whereby the clamping portion 56 of the clamping rod 50 can contact and press the object 12 (as shown in FIG. 5), and the object 12 can be rotated under the continuous rotation of the user. Open, it is quite convenient to use. It is worth mentioning that the rotary disassembly device 1 can be designed to be used for a single purpose according to the use of the normal use (unscrewing or locking). In other words, each of the teeth 42 is not limited to a ring. The driven tooth member 40 can be disposed on the same side of each of the driven tooth members 40, and the other side is a smooth surface, so that the respective clamping rods 50 are only opposite to each other. The same side of the base 20 is rotated, so that the user can clearly know the correct direction of rotation during use. For example, the driven tooth member 40A and the tooth portion 42A of the further preferred embodiment shown in FIG. 9 and FIG. 10, each of the tooth portions 42A is provided only on the left side of each of the driven tooth members 40A. And the right side of each of the driven tooth members 40A is a smooth surface, and the rotary dismounting device 1 is specifically used for unscrewing the object 12 to be opened, and when the operation flow of opening a large number of the objects 12 is performed, Save time and increase productivity.

In the process of combining the driven tooth member 40 and the clamping rod 50, referring to FIG. 2, if each of the clamping rods 50 is made of a rigid material such as metal, it is enclosed around each of the connecting holes 44. The material may be a slightly deformable plastic material, such that each of the latching heads 52 can pass through and be snapped into each of the connecting holes 44; it is understood that if each of the clamping rods 50 is made of elastic plastic or The rubber is made by the assembler, and the assembler only needs to insert the latching head 52 of the clamping rod 50 from the bottom into the connecting hole 44 of the driven tooth member 40, so that the latching head 52 is deformed by pressure and temporarily reduced. The assembly process is quite simple, when the card head 52 completely passes through the connecting hole 44, and the neck portion 54 of the clamping rod 50 is received in the connecting hole 44.

In addition, since the connecting hole 44 and the shape of the clamping rod 50 are simple in structure, the clamping rod 50 and the driven tooth member 40 can be firmly combined without any other components, and Reduce manufacturing difficulties while increasing manufacturing efficiency.

In addition, the clamping rod 50 is rotatably disposed on the driven tooth member 40, so that During the process of rotating the turntable 60 to bring the clamping rod 50 into contact and pressing the object 12, the structural design allows the clamping rod 50 to contact the object 12 with a larger area by rotating, or The slip between the two is reduced, making the article 12 easier to open.

Referring to FIG. 6 again, the rotary dismounting device 70 of another embodiment of the present invention is different in that the connecting hole 84 of the driven tooth member 80 has a large diameter portion 85 and a small diameter portion 86, and the clamping rod The latching head 92 of the 90 is received in the large diameter portion 85, and the neck portion 94 of the clamping rod 90 is received in the small diameter portion 86. In addition, as shown in FIG. 7, the turntable 60 of the present invention can also be eccentrically sleeved on the active tooth member 30 for increasing the torque, thereby reducing the difficulty of the user's operation. As shown in FIG. 8, a fixing member 221 is integrally extended under the upper clamping member 22 of the present invention. The fixing member is provided with a large and small diameter so as to be directly fastened to the lower clamping member 24, which makes it easier to assemble.
