In this patent document, Fig. 1-6 discussed below and the various implementations for describing the principle of the disclosure or method
Example is served only for illustrating, and should not be construed as in any way and limit the scope of the present disclosure.It should be understood by those skilled in the art that
, the principle or method of the disclosure can be realized in any mechanical structure suitably arranged.Refer to the attached drawing, the disclosure it is preferred
Embodiment will be described below.In the following description, the detailed description that well-known function or configuration will be omitted, in order to avoid
The theme of the disclosure is obscured with unnecessary details.Moreover, term used herein defines function according to the present invention.Cause
This, the term may according to the intention or usage of user or operator difference.Therefore, term used herein is necessary
Understood based on the description made herein.
As shown in Figure 1, a kind of brake gear of adaptive gravity high level fire disaster escaping rope crash facilities, including outer housing
100th, inner housing 200, elastic portion (compressed spring 700 in such as Fig. 1) and the braking parts being nested in outer housing 100.Inner casing
Body 200 is at least slidably connected in one direction with outer housing 100.Elastic portion connects inner housing 200 and outer housing 100, to apply
Add and 100 glide direction opposite effect power of inner housing 200 and outer housing.Braking parts are fixedly connected on outer housing 100 or inner casing
On body 200.Braking parts are used to respect to the amount of displacement slided change to rope according between inner housing 200 and outer housing 100
800 drag sizes applied when pulling out.In this disclosure, outer housing 100 and inner housing 200 are either with continuous envelope
(space that skeleton surrounds can for the housing (such as sleeve class formation) for the face structure for closing surface or simply skeleton structure
It is envisioned for virtual surface), i.e., it is at least slidably connected in one direction between outer skeleton and inner frame.Under normal circumstances, it is sliding
Dynamic connection is mainly included in glide direction sets the sliding bar identical with glide direction and hole to form and slide in inner and outer shell respectively
Dynamic structure or in glide direction respectively inner and outer shell setting with glide direction vertical sliding motion bar and with slip side
