According to the utility model discloses slewing mechanism, refer to fig. 1, including rotating bracket 110, fixed baseplate 120, connecting piece 130 and rough surface 140, rotating bracket 110 sets up to hollow rod structure, be provided with two fixed columns 121 on the fixed baseplate 120, two fixed columns 121 are used for the fixed rotating bracket 110 of centre gripping, connecting piece 130 is used for connecting fixed baseplate 120 and rotating bracket 110, be used for making rotating bracket 110 rotate for fixed baseplate 120, rough surface 140 sets up on fixed baseplate 120 and the contact surface of rotating bracket 110, be used for increasing the frictional force between fixed baseplate 120 and the rotating bracket 110.

For example, referring to fig. 2, the rotating bracket 110 is provided in a hollow bar structure, and one end portion of the hollow bar is provided with two opposite first fixing holes 111, which are provided at one end portion of the hollow bar to increase a rotatable range of the rotating bracket. At one side end near the first fixing hole 111, the hollow bar is provided with a boss 114 having one side protruding outward. The first fixing hole 111 is disposed corresponding to the second fixing hole 123 for passing through the connecting member 130. The other end of the rotating support 110 is provided with a fixed seat 112, the fixed seat 112 is in a round table structure, and a threaded hole 113 is formed in the center of the round table, so that an external component can be connected with the fixed seat 112 in a rotating mode, and replacement and disassembly are facilitated.

Referring to fig. 3, the bottom plate of the fixing base 120 is provided with base fixing holes 122, the base fixing holes 122 are used for fixing the fixing base 120 to the installation position, and preferably, two base fixing holes 122 are provided, and the fixing base 120 can be fixed to the installation position by passing through the base fixing holes 122 through a screw fastener in use. A part of the bottom plate of the fixing base 120 is bent to form two fixing posts 121, the fixing posts 121 are perpendicular to the bottom plate of the fixing base 120, and the bottom plate of the fixing base 120 is integrally of a T-shaped structure. The two fixing posts 121 are provided with second fixing holes 123 for allowing the connecting member 130 to pass therethrough, thereby fixing the rotating bracket 110 and the fixing base 120. Because the fixing posts 121 are integrally formed by bending, the two fixing posts 121 can change the gap between them under the action of external force. The gap between the two fixing posts 121 is used for clamping and fixing the rotating bracket 110, so that the rotating bracket 110 can rotate in a plane around the fixing base 120. Be provided with recess 124 on fixed baseplate 120's the bottom plate, recess 124 is the rectangle, a bulk strength for increasing fixed baseplate 120's bottom plate, make the bottom plate be difficult to buckle and warp, increase life, and at the during operation, recess 124 can agree with the boss 114 on the rotating bracket 110, play the effect of spacing fixed rotating bracket 110, for example, the shorter time that recess 124 set up, rotating bracket 110 is when rotating, the boss 114 can touch the one end of recess 124, thereby the size of restriction rotating bracket 110's rotation range, can be according to the nimble size that sets up the recess of actual demand, thereby control rotating bracket's rotation range.

The connecting member 130 fixes the rotating bracket 110 and the fixed base 120 such that the rotating bracket 110 can rotate around the fixed base 120 in the same plane. When the extrusion force of the connecting piece 130 to the two fixing columns is large, the two fixing columns 121 can be slightly deformed, so that the rotating bracket 110 is tightly clamped, and the friction force generated when the rotating bracket 110 rotates is increased.

When the rotating bracket 110 is combined with the fixed base 120 through the connecting member 130, two contact surfaces are formed between the rotating bracket 110 and the fixed base 120, and a rough surface 140 is provided on both contact surfaces, thereby increasing friction when the rotating bracket 110 and the fixed base 120 rotate. In other embodiments, only one rough surface may be provided on only one side of the contact surface, and the effect of increasing the friction force may also be achieved. The rough surface 140 is not an additional component, and in order to be directly provided on the rotating bracket 110 or the fixed base 120, the regions thereof that need to be in contact with each other are polished to a rough structure. The rough surface 140 is formed as an uneven rough structure, or formed as a cross grain, a vertical grain, a small protrusion, etc., for increasing the sliding friction between the contact surfaces thereof and increasing the rotation frequency of the rotating mechanism.

In some embodiments of the present invention, the rough surface 140 is disposed on the rotating bracket 110. The rough surface 140 is disposed on the area of the rotating bracket 110 that needs to contact with the fixing base 120, and the corresponding area of the fixing base 120 is not disposed with the rough surface 140, so that when the fixing base 120 is made of plastic, a better fixing effect can be achieved.

In one embodiment, the rough surface 140 is disposed on the fixed base 120, and the rough surface 140 is disposed on the fixed base 120 and functions the same as that of the rotating bracket 110, which will not be described herein again.

In other embodiments, the rotating bracket 110 is provided with a rough surface 140, and the fixed base 120 is provided with a rough surface 140. Rough surfaces may be provided on both the rotating bracket 110 and the fixed base 120, that is, when the rotating bracket 110 and the fixed base 120 are combined, the two rough surfaces are provided to directly contact each other, and the friction between the contact surfaces is greater.

In some embodiments of the present invention, the connecting member 130 is a glued locknut. The connecting piece 130 is provided with the rubber locknut, so that the mounting and the dismounting are convenient, the wear resistance and the shearing resistance of the rubber locknut are strong, the anti-seismic performance is good, the locking capability can be better still after the rotating bracket 110 rotates for multiple times, and the looseness can not be generated. In other embodiments, non-detachable fastening rods may be used for the connection, and may also have excellent multi-turn performance.

In some embodiments of the present invention, a damping washer 150 is disposed between the contact surface of the fixed base 120 and the rotating bracket 110. The damping gasket 150 is in a circular ring shape, correspondingly, the rough surface 140 is also in the same circular ring shape, the damping gasket 150 is added, so that the abrasion of the rough surface 140 in use can be reduced, the use frequency of the rough surface 140 is improved, the damping gasket 150 is convenient to replace, meanwhile, the contact surfaces of the rotating support 110 and the fixed base 120 are also protected, and the service life of the rotating mechanism is prolonged.

In some embodiments of the present invention, the damping shim 150 is a nylon material. Compared with a gasket made of a metal material, the nylon material has excellent insulating, corrosion-resistant, heat-insulating and non-magnetic properties, light weight, low cost and better protection performance on a rough surface.
