Description

Technical Field

[0001] The utility model belongs to the technical field of rotators, and in particular relates to a rotator which is convenient for disassembly and assembly. Background Art

[0002] The stunt bicycle's rotator is installed at the handlebars of the bicycle. Through the action of the rotator, the brake line will not be entangled after the handlebars are turned, thereby achieving the effect of freely rotating the handlebars.

[0003] Publication No. CN201105780Y discloses a dust cover device for a stunt bicycle spinner, which achieves a dustproof effect by providing a dustproof structure;

[0004] However, the above patent does not disclose how to implement the maintenance function for the internal ball bearings. The rotator mainly relies on the ball bearings to achieve rotation. During long-term rotation, the ball bearings are greatly worn, which may easily affect the normal rotation in the later stage. The current maintenance method can only disassemble the rotator for maintenance. This method is relatively cumbersome, inefficient, and difficult. Therefore, it has great limitations in actual use and has room for improvement. Utility Model Content

The oil drain pipe is connected to the supporting ring through and is located directly above the ball, so as to achieve lubrication of the ball; an oil guide part, one end of which is connected to the oil filling ring and the other end is connected to the outer sleeve, and the guide part is exposed to the outer surface of the outer sleeve. In use, lubricating oil can be injected through the guide part, and then transported to the oil filling ring by the guide part, and finally transmitted to the position of the ball through the oil guide pipe, thereby completing the lubrication of the ball surface, reducing the wear of the ball caused by the large friction during use, and achieving maintenance of the ball.

[0007] Preferably, a placement ring is provided on the top end surface of the support ring, the oil drain pipe is located inside the placement ring, and a through hole is provided on the inner bottom end surface of the placement ring. During lubrication, the lubricating oil falling into the placement ring can flow into the ball through the through hole to achieve lubrication.

[0008] Preferably, a sponge ring is also placed inside the placement ring. The sponge ring is located directly below the oil drain pipe. When the lubricating oil is injected, it will be absorbed by the sponge ring to avoid waste caused by directly injecting the lubricating oil. After the sponge ring absorbs more lubricating oil, it slowly drips into the through hole and falls onto the ball to achieve continuous lubrication.

[0009] Preferably, a brake line 2 is also installed on the outer sleeve, and the brake line 2 is fixed to the edge of the connecting ring. Therefore, when the outer sleeve rotates, the connecting ring will be driven to rotate synchronously through the brake line 2. At this time, the connecting ring will rotate with the support ring through the ball bearings.

[0010] Preferably, a brake line 1 is also installed on the fixed ring, and the brake line 1 is connected to the bent part at the bottom of the support ring to support the bottom of the support ring, and the connecting ring can support the top of the support ring under the support of brake line 2, so that the outer sleeve and the connecting ring are supported by the fixed sleeve and the fixed ring. Since the brake line 1 and the brake line 2 are in a separated state, when the outer sleeve rotates, there will be no crossing problem between the brake line 1 and the brake line 2.

[0011] Preferably, the oil guide portion is an oil guide pipe connected to the top of the oil filling ring, an oil filling hole is opened on the top side of the outer sleeve, and the end of the oil guide pipe passes through the oil filling hole and extends to the external opening position of the oil filling hole.

[0012] Preferably, a mounting ring is inserted into the top of the outer sleeve, and the mounting ring is threadedly connected to the vehicle bar. During disassembly, the mounting ring is separated from the vehicle bar, and then the outer sleeve is pulled away from the mounting ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The designed lubrication component can squeeze out the built-in lubricating oil by pressing down, thereby lubricating the surface of the ball and maintaining the ball, avoiding high friction of the ball during long-term use, and extending the service life. In this way, there is no need for disassembly, and the operation is more convenient. At the same time, the lubrication component is also convenient for adding lubricating oil, further improving the convenience of use. BRIEF DESCRIPTION OF THE DRAWINGS
