Detailed Description

In order to more clearly illustrate the embodiments of the present invention, the following description will explain embodiments of the present invention with reference to the accompanying drawings. It is obvious that the drawings in the following description are only examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.

Example 1:

as shown in fig. 1 to 4, the roller guide shoe for a rucksack-type elevator of the present embodiment, which has an adjustable pressing force, includes a base 0, a first roller 1, a second roller 2, and a third roller 3.

The base 0 is of a flat plate structure, and occupies a small space; the base 0 has an avoidance hole 10 for avoiding the assembly of the second roller 2.

The first roller 1 and the third roller 3 are arranged on the base 0 at intervals so as to be clamped on two sides of the guide rail I relatively. Specifically, two first rollers 1 are arranged, distributed along the length direction of the guide rail I and positioned on the same side of the guide rail I; in order to improve the stability of the first roller 1 and the third roller 3 clamping the guide rail, the axis of the third roller 3 is located on the central line of the connecting line of the axes of the two first rollers. In addition, in order to prevent the situation that the first roller is easily separated from the guide rail when the first roller is independently used, the two first rollers 1 are adopted in the embodiment and are both installed on the linkage seat 4, and the linkage seat 4 is rotatably installed on the base 0, so that the first rollers are ensured not to be separated from the guide rail; the two first rollers 1 are respectively positioned at two sides of the rotating fulcrum of the linkage seat. Wherein, the linkage seat 4 is a flat structure and is parallel to the base 0; the first roller 1 is installed on the linkage seat 4 through a first wheel shaft, and the linkage seat 4 is installed on the base 0 through a rotating shaft, so that the radial direction of the first roller 1 is parallel to the plane where the base 0 is located.

The third roller 3 is mounted on the base 0 by a third axle such that the radial direction of the third roller 3 is parallel to the plane of the base 0.

In addition, a pressing force adjusting mechanism K is installed on the base 0 corresponding to the avoidance hole 10, and the pressing force adjusting mechanism K is used for adjusting the pressing force between the second roller 2 and the guide rail I. Specifically, the pressing force adjusting mechanism K comprises a swing arm K1, a guide post K2, an elastic piece K3 and a limiting piece K4, the second roller 2 is mounted in the middle of the swing arm K1, and the second roller 2 penetrates through the avoiding hole 10 of the base to abut against the guide rail; the lower end of the swing arm K1 is hinged on the hinge seat 11 at the lower side of the avoidance hole of the base, the upper end of the swing arm K1 stretches across the avoidance hole of the base and is movably matched with a guide post K2 fixedly installed at the upper side of the avoidance hole of the base, and the guide post K2 is installed perpendicular to the base 0; the elastic piece K3 is sleeved outside the guide post K2 and is positioned on one side of the swing arm K1 away from the avoidance hole of the base, the inner end of the elastic piece K3 abuts against the swing arm K1, and the outer end of the elastic piece K3 is limited by a limiting piece K4; the limiting member K4 is screwed to the guiding post K2 so as to adjust the elastic force of the elastic member K3 and thus adjust the pressing force between the second roller 2 and the guiding rail I.

Specifically, swing arm K1 is located one side of second gyro wheel 2, and the upper end threaded connection of swing arm K1 has screw pin K5, and screw pin K5 has radial perforating hole for guide post K2 runs through. The contact surface of the elastic piece K3 and the threaded pin shaft K5 is a plane, so that the stability of pressing force is improved.

In addition, a spring seat K6 is arranged between the limiting piece K4 and the elastic piece K3, and the stability of pressing force is further improved. The stopper K4 is preferably a nut, and the elastic member K3 is a spring.

A limiting sleeve K7 is further arranged between the spring seat K6 and the threaded pin shaft K5, and the limiting sleeve K7 is sleeved outside the guide column K2 and is located in an inner cavity of the elastic piece K3; and the limiting sleeve K7 is used for limiting the movable stroke of the threaded pin shaft.

Wherein, the rotation plane of the second roller 2 is vertical to the rotation plane of the first roller 1, so that each roller on the roller guide shoe is matched with the guide rail of the elevator.

Example 2:

the pressing force adjustable roller guide shoe for a rucksack type elevator of the present embodiment is different from that of embodiment 1 in that:

the third roller is replaced by a sliding block which is fixedly arranged on the base, has the same action as the third roller and is used for clamping on the guide rail; the requirements of different applications are met;

other structures can refer to embodiment 1.

Example 3:

only one first roller is arranged and is opposite to the third roller; the requirements of different applications are met;

other structures can refer to embodiment 1.

The foregoing has been a detailed description of the preferred embodiments and principles of the present invention, and it will be apparent to those skilled in the art that variations may be made in the specific embodiments based on the concepts of the present invention, and such variations are considered as within the scope of the present invention.
