Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1 to 6, the embodiment provides a guide rail mechanism with a fixed-length damping effect, which includes a guide rail 1 and a bearing assembly, where the bearing assembly includes a supporting seat 2, a rotating shaft 3 and a bearing 5, the supporting seat 2 and the bearing 5 are respectively fixed at upper and lower ends of the rotating shaft 3, the supporting seat 2 is used for fixing a seat 12, and the bearing 5 is used for driving the supporting seat 2 to move linearly along the guide rail 1. The bearing 5 sets up in guide rail 1, and the supporting shoe sets up outside guide rail 1, and the upper end cover of pivot 3 is equipped with nut 4 and carries on spacingly, and the lower extreme of pivot 3 is fixed with baffle 6 through screw 7, baffle 6 and bearing 5 laminate mutually, and 6 cooperation of baffle through the bearing 5 below are located the supporting seat 2 of bearing 5 top to do the rectilinear sliding with bearing 5 restriction in guide rail 1. Meanwhile, two ends of the guide rail 1 are provided with baffle plates to prevent the bearing 5 from sliding out of the guide rail 1.

Guide rail 1 includes fast moving district and buffering retardation area, buffering retardation area is provided with the spring leaf 8 that the bearing assembly card that will move stagnates in retardation area, spring leaf 8 includes spring leaf main part 803 and sets up fixed part 801 and movable part 802 at spring leaf main part 803 both ends respectively, spring leaf main part 803 is protruding to keeping away from guide rail 1 one side, and is provided with a plurality of alternate jamming grooves 806 on spring leaf main part 803 for spring leaf main part 803 is wave shape, so that through jamming grooves 806 with the bearing 5 jamming. The fixing portion 801 is provided with a threaded hole 804, a fixing bolt 9 fixedly connecting the fixing portion 801 and the guide rail 1 is arranged in the threaded hole 804, a waist-shaped hole 805 is arranged in the extending direction of the guide rail 1 of the movable portion 802, a joint bolt 10 fixing the movable portion 802 and the guide rail 1 is arranged in the waist-shaped hole 805, and after the joint bolt 10 fixes the movable portion 802 and the guide rail 1, a moving gap needs to be kept between the movable portion 802 and the guide rail 1, so that when the spring leaf main body 803 is pressed, a certain ductility is formed in the direction parallel to the guide rail 1, elastic deformation of the spring leaf 8 after the spring leaf 8 receives a normal force given by the bearing 5 is increased, the service life of the spring leaf 8 is prolonged, and the operation resistance of a user for moving the seat 12 is also reduced.

As can be seen from the above, the guide rail mechanism with fixed-length damping function provided in this embodiment, when in use:

when a user sits on the seat 12 and easily pedals the seat 12 by feet at the section of the guide rail 1 without the spring leaf 8, and when the seat 12 is moved at the section of the guide rail 1 with the spring leaf 8, the user only needs to sit on the seat 12 and forcibly push the seat 12 by legs to move the seat 12 to the position where the spring leaf 8 has the clamping stagnation groove 806, because the spring leaf 8 has certain elasticity and is compressed and deformed after being stressed to approach one side of the guide rail 1, the friction force can be increased after the bearing 5 is contacted with the spring leaf 8, so that the damping effect is provided for the movement of the supporting seat 2, when the seat 12 reaches the position needing stagnation, the feet do not use force any more, the spring leaf 8 has the resetting trend, a reaction force is applied to the supporting seat 2, so as to limit the seat 12, therefore, the process does not need to manually or operate other devices to fix the position of the seat 12, and the operation of the seat 12 is more convenient and faster, Is humanized.

It should be noted that one of the load bearing assemblies shown in fig. 1 is the structure with the support base removed.
