Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Referring to fig. 1 and 2, the utility model discloses a limited rotation seat of turned angle, including main seat frame 1, pivot subassembly 2, chassis 3 and pivot stop device 4. Wherein, the main seat frame 1 is connected with a rotating shaft 21 of the rotating shaft component 2, the chassis 3 is connected with a base 22 of the rotating shaft component 2, and the main seat frame 1 can rotate relative to the chassis 3 through the rotating shaft component 2; the rotating shaft limiting device 4 is arranged between the main seat frame 1 and the rotating shaft assembly 2 to limit the rotating angle of the main seat frame 1 relative to the chassis 3, and the problem of connection wire winding caused by infinite rotation of the main seat frame 1 is avoided.

The rotating shaft assembly 2 is an existing unlimited rotating shaft assembly, the rotating shaft 21 and the base 22 of the rotating shaft assembly 2 can be of a hollow structure or a solid structure, namely, the connecting wires can be routed from the inside or the outside of the rotating shaft assembly 2. Of course, the solution of the present embodiment is more suitable for the rotating shaft assembly 2 with a hollow structure.

Specifically, referring to fig. 2 and 3, the rotating shaft limiting device 4 includes a fixing sleeve 41, a first limiting rod 42 and a second limiting rod 43, the fixing sleeve 41 is detachably sleeved on the base 22 of the rotating shaft assembly 2, the first limiting rod 42 is disposed on the fixing sleeve 41, so that the first limiting rod 42 can be fixed relative to the base 22, the second limiting rod 43 is disposed on the main seat frame 1, and the second limiting rod 43 abuts against or separates from the first limiting rod 42 along with the rotation of the main seat frame 1, so as to limit the rotation angle of the main seat frame 1.

In the above scheme, the fixed sleeve 41 is detachably sleeved on the base 22 of the rotating shaft component 2, and then the rotation angle of the main seat frame 1 relative to the chassis 3 is limited by the cooperation of the two limit rods 42 and 43, so as to avoid the problem of winding of the connecting wires; on the other hand, still can be through the setting to fixed cover 41 size to the pivot subassembly 2 of multiple specification of adaptation makes to rotate the seat and joins in marriage when joining in marriage pivot subassembly 2 and be difficult to cause the mistake, only need judge whether install pivot stop device 4 additional can, be convenient for batch production.

More importantly, the first position-limiting rod 42 is indirectly and detachably mounted on the base 22 of the rotating shaft assembly 2 by using the fixing sleeve 41 as an intermediate member, and there is no need to open a screw hole on the base 22 to fix the first position-limiting rod 42, and damage to the base 22 can be avoided, especially the hollow rotating shaft assembly 2 has a thinner base 22 wall thickness, and when the first position-limiting rod 42 is directly fixed on the base 22, the wall thickness of the base 22 is easily penetrated, or the wall thickness of the base 22 is easily deformed by force, so that relative rotation between the rotating shaft 21 and the base 22 is affected.

In addition, it can be understood that the rotation range of the main seat frame 1 can be limited to about 330 degrees by setting the mounting positions and the sizes of the first limit lever 42 and the second limit lever 43 differently. Of course, the rotation range of the main frame 1 may be other values, and infinite rotation may be avoided.

Referring to fig. 3 and 4, in the present embodiment, three first screw holes 411 are arranged on the circumferential side wall of the fixing sleeve 41, and three fixing screws 44 respectively penetrate through the corresponding first screw holes 411 from outside to inside and abut against the outer side wall of the base 22. Thus, the fixing screw 44 abuts against the outer side wall of the base 22 to detachably mount the fixing sleeve 41, so that possible damage to the base 22 when the fixing sleeve 41 is mounted can be well avoided, the structure is simple, and the mounting is convenient.

Of course, in other preferred embodiments, the number of the first screw holes 411 and the number of the fixing screws 44 may also be two, four, five, etc., which is not limited in the present invention.

In particular, the fixing screws 44 are set screws with sharp feet, so as to increase the grip of the fixing screws 44 on the base 22, to better fix the fixing sleeve 41 on the base 22.

In addition, in other preferred embodiments, the retaining sleeve 41 can be mounted to the base 22 in other ways, such as snap fit, clamping, etc., which may not be as convenient as the retaining screw 44, but can also allow for a removable attachment of the retaining sleeve 41 to the base 22.

Specifically, the fixing sleeve 41 is annular, and its inner diameter is larger than the outer diameter of the base 22, and the fixing sleeve 41 can be well applied to the rotating shaft assemblies 2 of various specifications by combining the connecting function of the fixing screw 44, for example, in the rotating shaft assemblies 2 of different specifications, the outer diameter of the base 22 can fluctuate within a certain range, and the fixing sleeve 41 can be applied.

In other embodiments, the housing 41 may have an oval or polygonal shape, such that the diameter of the inscribed circle of the housing 41 is larger than the outer diameter of the base 22, so as to satisfy the requirement that the housing 41 can be mounted on bases 22 with various specifications within a certain outer diameter range.

Referring to fig. 3 and 4, in the present embodiment, preferably, the first position-limiting rod 42 is a screw, and the fixing sleeve 41 is provided with a second screw hole 412 screwed with the screw, so as to implement the installation of the first position-limiting rod 42 on the fixing sleeve 41.

In particular, the first limit stop 42 is arranged to extend radially of the fixing sleeve 41, and it is also considered that the first limit stop 42 extends horizontally to achieve a longer projection length with a shorter first limit stop 42, so as to better engage against the second limit stop 43.

Referring to fig. 1 and fig. 2, in the present embodiment, preferably, the second position-limiting rod 43 is disposed on the rotating shaft sleeve of the main seat frame 1 and extends in the vertical direction, so that the first position-limiting rod 42 horizontally abuts against the second position-limiting rod 43 vertically, the material consumption is minimal, and the sliding is not easy.

To sum up, the utility model discloses a restricted rotation seat of turned angle, the suitability is high: the rotation angle of the main seat frame 1 can be limited, the connection wire is prevented from being wound, and the rotating shaft assembly 2 with various specifications can be adapted by setting the size of the fixed sleeve 41, so that errors are not easily caused when the rotating seat is assembled with the rotating shaft assembly 2, and only the rotating shaft limiting device 4 needs to be additionally arranged or not, and the mass production is facilitated; simple structure, simple to operate, and do not harm base 22: the fixing sleeve 41 is mounted on the base 22 through the fixing screw 44, and the first limit rod 42 is screwed and fixed on the fixing sleeve 41, so that the whole structure of the rotating shaft limiting device 4 is simple, the mounting and the use are very convenient, a screw hole does not need to be formed on the outer side wall of the base 22 to fix the first limit rod 42, and the base 22 cannot be damaged.
