Description

Rotating structure for treadmill

Technical Field

The utility model belongs to the technical field of treadmill technique and specifically relates to revolution mechanic for treadmill.

Background

Treadmills are home and gym equipment that enable a user to perform running or walking exercises while remaining in a relatively fixed position.

Slewing mechanism on the traditional treadmill receives the influence of treadmill vibrations easily, leads to its rotation junction to produce not hard up, and the rotation junction of treadmill handrail especially is most obvious, leads to the treadmill structure unstable, and easily produces the abnormal sound, influences user's experience, and the maintenance frequency is high.

SUMMERY OF THE UTILITY MODEL

The utility model provides a revolution mechanic for treadmill to not enough among the prior art.

In order to solve the technical problem, the utility model discloses a following technical scheme can solve: rotary structure for treadmill, including the mounting, rotate piece and screw rod, set up threaded hole on the mounting, one side is provided with the connecting axle on the mounting, set up on the connecting axle with the first connecting hole of screw hole intercommunication, the lower part one side of rotating the piece set up with the first hole of changeing of connecting axle matched with, be provided with first plastic gasket in the first hole of changeing, the second of changeing the lower part opposite side of rotating the piece has been seted up and has been changeed the hole, the second changes the downthehole second plastic gasket that is provided with, the second change the hole through seting up rotate the second connecting hole of lower part department and with first hole of changeing link up, the screw rod passes in proper order the second plastic gasket the second connecting hole first plastic gasket with behind the first connecting hole with screw hole threaded connection. Through improving revolution mechanic, when can effectively locking rotating the piece, rotate the normal rotation that can also be smooth and easy for the treadmill when using, should rotate the relevant structure of junction and can not become flexible, eliminate the hidden danger that should locate to produce the abnormal sound, improve user's good experience degree, reduce maintenance frequency.

In the above technical solution, preferably, the threaded portion of the screw rod is in threaded connection with the threaded hole, extends to the outside of the threaded hole, and is then in threaded connection with a nut. Through addding the nut, promote revolution mechanic's stability for should rotate the junction and more be difficult for producing not hard up.

Among the above-mentioned technical scheme, it is preferred, the connecting axle outer wall is including a plurality of first stoppers, first commentaries on classics downthehole wall be provided with a plurality of with first stopper complex second stopper, the quantity of first stopper is two and the symmetry sets up on the connecting axle outer wall, the quantity of second stopper is two and the symmetry sets up on the inner wall in first commentaries on classics hole. Through the cooperation structure of designing first stopper and second stopper, inject the rotation stroke of rotating the piece for the piece that rotates can automatic positioning after upset to the settlement position, also can be by spacing support when accomodating, and the upset stroke causes relevant wearing and tearing with ground contact after too big when avoiding accomodating.

In the above technical solution, preferably, the first plastic gasket has the same shape and size as the second plastic gasket. The left side and the right side are corresponding, and the stability of rotation is improved.

In the above technical solution, preferably, the screw rod includes a polished rod portion close to the head portion and a threaded portion far away from the head portion, and a contact portion of the screw rod and the first plastic gasket, the second connection hole and the second plastic gasket is the polished rod portion. Only contact with polished rod portion when rotatory, promote rotatory smooth and easy degree.

The utility model has the advantages that: the utility model discloses an improve revolution mechanic, when can will rotating effective locking, still guarantee to rotate smooth and easy normal rotation for the treadmill is when using, should rotate the relevant structure of junction and can not become flexible, eliminates the hidden danger that this department produced the abnormal sound, improves user's good experience degree, reduces maintenance frequency.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1-3, the rotating structure for a treadmill includes a fixed member 1, a rotating member 2, a screw rod 3, a first plastic washer 4, a second plastic washer 5, and a nut 6.

The fixing piece 1 is arranged on a frame of the treadmill, a threaded hole is formed in the fixing piece 1 from one side to the other side in a penetrating mode, a connecting shaft 11 is arranged on one side of the fixing piece 1, the outer wall of the connecting shaft 11 comprises a plurality of first limiting blocks 12, the number of the first limiting blocks 12 is preferably two, the first limiting blocks are symmetrically arranged on the outer wall of the connecting shaft 11, and meanwhile a first connecting hole 13 communicated with the threaded hole is formed in the connecting shaft 11.

The lower part one side of rotating piece 2 seted up with connecting axle 11 matched with first commentaries on classics hole 21, first commentaries on classics hole 21 inner wall be provided with a plurality of with first stopper 12 complex second stopper 22, preferably, the quantity of second stopper 22 is two and the symmetry sets up on the inner wall of first commentaries on classics hole 21.

The distance between two second stopper 22 determines the home range of first stopper 12, when setting for above-mentioned distance, only need can guarantee to rotate piece 2 can rotate and set for the position can, preferably, the diameter size of second stopper 22 is less than the diameter size of first stopper 12.

First plastic gasket 4 sets up in first commentaries on classics hole 21, second commentaries on classics hole 23 has been seted up to the lower part opposite side of rotating piece 2, second plastic gasket 5 sets up in second commentaries on classics hole 23, second commentaries on classics hole 23 through seting up rotate the second connecting hole 24 of 2 lower parts departments of piece and with first commentaries on classics hole 21 link up.

Preferably, the first plastic gasket 4 and the second plastic gasket 5 have the same shape and size. Because of first plastic gasket and second plastic gasket are nonmetal gasket, consequently, are being locked the back, rotate the piece and still can rotate.

Screw rod 3 is including the polished rod portion 31 that is close to the head and the screw thread portion 32 of keeping away from the head, screw rod 3 passes in proper order second plastic gasket 5 second connecting hole 24 first plastic gasket 4 with behind the first connecting hole 13 with screw hole threaded connection, screw rod 3 with first plastic gasket 4
