Detailed description of the invention
This application provides one and face limit opening protective device, achieve the loaded down with trivial details secondary construction problem solving and face limit opening protective device and bring.
Below in conjunction with the accompanying drawing in the embodiment of the present application, carry out clear, complete description to the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment of the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
The structural representation facing limit opening protective device that Fig. 1 provides for the application, the scheme of installation facing limit opening protective device that Fig. 2 provides for the application.
What the application provided faces limit opening protective device, comprise outer tube 1 and built-in fitting 2, the first end of outer tube 1 is provided with internal thread, built-in fitting 2 is shaft-like or tubulose, its first end is provided with external screw thread, the first end of outer tube 1 is threaded with the first end of built-in fitting 2, and the second end of outer tube 1 and the second end of built-in fitting 2 are respectively arranged with elastomeric pad.Outer tube 1 is a long tube, and built-in fitting 2 is connected with it by screw thread, and can adjust by turn the length that it is positioned at outer tube 1 outside, and built-in fitting 2 can be tubulose, also can be shaft-like, and the two ends facing limit opening protective device are elastomeric pad.In use, first adjustment makes its length shorter to this device, then lies in a horizontal plane in and faces hole, limit place, and rotate and make it extend, the elastomeric pad at its two ends is resisted against the both sides Dong Bi facing hole, limit, realizes fixing.This structure is easy to installation and removal, avoids secondary construction, achieves the loaded down with trivial details secondary construction problem solving and face limit opening protective device and bring.
In the application one specific embodiment, the first end of outer tube 1 is provided with the through bolt hole of ecto-entad, is fitted with conflict bolt in its introversion, and the front end of conflict bolt is resisted against the outside wall surface of the first end of built-in fitting 2.In order to prevent fixing after, face limit opening protective device and loosen and drop, especially, introduce conflict bolt, the first end of built-in fitting 2 is withstood in its end screwing in sidewall, makes it be difficult to loosen, further, this conflict bolt and the bolt hole corresponding with it can be set to multipair.
