Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used herein for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model is described in detail below with reference to the attached drawing figures: the utility model discloses an anti-falling guide rail type elevator, which comprises a support frame 1, wherein a lifting seat 2 is arranged in the support frame 1 in a sliding manner, upright posts 14 are arranged at two ends of the support frame 1, slide ways 6 are arranged on the upright posts 14, slide blocks 7 matched with the slide ways 6 are arranged in the slide ways 6 in a sliding manner, rubber blocks 8 are arranged at two ends in the slide blocks 7 in a sliding manner, the rubber blocks 8 are contacted with the slide ways 6, so that certain initial friction force is provided, the initial friction force is slightly larger than the gravity of the slide blocks and internal components, the rubber blocks 8 are connected with a driving block 9, a spring B is arranged between the driving block 9 and a limiting groove 10, and one side of the driving block 9 is of an inclined surface structure; a clamping block 11 is connected to the lifting seat 2, a chamfer structure matched with the inclined plane of the driving block 9 is arranged at the end part of the clamping block 11, and an opening matched with the clamping block 11 is formed in the side wall of the sliding block 7; a stroke groove 12 is arranged in the sliding block 7, a sliding rod 13 matched with the stroke groove 12 is arranged on the lifting seat 2, a spring A is arranged between the sliding rod 13 and the bottom of the stroke groove 12, and when the spring A is in the initial length, the elastic force of the spring A is equal to the initial friction force between the rubber block 8 and the slide 6.
