1. the guide wheel set comprises a guide wheel set, 2, a sliding frame, 3, a guide column, 4, a guide wheel set mounting hole, 11, a guide wheel, 12, a guide wheel shaft, 13, a fastening screw, 14, a spacer bush, 15 and a bearing.

Detailed Description

In order to clearly illustrate the technical features of the present solution, the present solution is explained below by way of specific embodiments.

As shown in fig. 1-4, the utility model discloses a guide structure for fitness equipment, including two vertical guide posts 3, along the vertical gliding carriage 2 of guide post 3 and install 4 direction wheelsets 1 on carriage 2.

The sliding frame 2 can be a counterweight frame used for installing a balancing weight and can also be a guide frame used for guiding other moving parts, the sliding frame 2 in the embodiment is a guide frame in a pull-up booster, the pull-up booster is fixedly connected with a supporting plate, the sliding frame 2 is also connected with a boosting rope, when the lifting device is used by a user, the user holds a cross bar at the top of the pull-up booster by a hand, kneels on the supporting plate, upwards pulls the supporting plate through the boosting rope to provide upwards thrust, and therefore the body of the user is assisted to move upwards, and the pull-up boosting effect is achieved.

The sliding frame 2 is in an inverted U shape formed by bending a steel plate, the sliding frame 2 comprises a horizontal bottom plate arranged above and two vertical plates arranged below the bottom plate, and the guide wheel set 1 is arranged between the two vertical plates.

The guide wheel set 1 comprises a guide wheel shaft 12 positioned between two vertical plates, a guide wheel 11 connected to the guide wheel shaft 12 in a shaft mode, and fastening screws 13 installed at two ends of the guide wheel shaft 12, a guide wheel set installation hole 4 is formed in the sliding frame 2, and the fastening screws 13 penetrate through the guide wheel set installation hole 4 and are fastened to the end face of the guide wheel shaft 12. The two ends of the guide wheel shaft 12 are respectively propped against the inner sides of the two vertical plates, a bearing 15 is arranged between the guide wheel 11 and the guide wheel shaft 12, and a spacer 14 is arranged between the bearing 15 and the vertical plates, so that the bearing 15 can be prevented from moving left and right.

Two 3 vertical settings of guide post and be parallel to each other, direction wheelset 1 all sets up the inboard of two guide post 3 or all sets up the outside at two guide post 3, and direction wheelset 1 all sets up the inboard at two guide post 3 in this embodiment.

Every guide post 3 corresponds two direction wheelsets 1, and 4 direction wheelsets 1 that two guide posts 3 correspond are the rectangle and arrange.

The guide post 3 is cylindrical, and the outer circumferential surface of the guide wheel 11 is an arc-shaped surface matched with the guide post 3.

The direction wheelset 1 is connected with carriage 2 through threaded fastener, threaded fastener in this embodiment is fastening screw 13, it has direction wheelset mounting hole 4 to open on the carriage 2, the slot hole that direction wheelset mounting hole 4 that the direction wheelset 1 that an at least guide post 3 corresponds sets up for the slope, only the slot hole that direction wheelset mounting hole 4 that the direction wheelset 1 that a guide post 3 corresponds sets up for the slope in this embodiment, the round hole that direction wheelset mounting hole 4 that another guide post 3 corresponds the direction wheelset 1 only supplies fastening screw 13 to pass through.

The included angle of slot hole and vertical face is 5~30 degrees, and the angle in this embodiment is 10 degrees, because the angle is very little to realize fastening screw 13 auto-lock in the slot hole, when leading wheel 11 bears the lateral force, can not lead to fastening screw 13 to slide along the slot hole because of the lateral force.

The long holes of the two guide wheel sets 1 corresponding to the same guide column 3 are opposite in inclination direction.
