Further, on described slide, the position of corresponding backstay is provided with bearing, is provided with and applies to move interior stage clip to locating hole to backstay in described bearing.
Further, described mild steel damper comprises outside framework, is positioned at the inner frame of outside framework and lays respectively at inter and outer gimbal and be arranged in parallel inside and outside damping unit, described outside framework is connected with the baffle plate stretched in inner frame, the two ends of described external damping unit respectively with the outer wall of inner frame and the contact internal walls of outside framework, the two ends of described internal damping unit contact with baffle plate with the inwall of inner frame respectively, and described slide connects on inner frame.
Further, described inside and outside damping unit, lay respectively at the both sides of the same frame plate of inner frame.
The beneficial effects of the utility model: mechanical self-latching type mild metal damper of the present utility model, comprises mild steel damper, also comprise self-locking mechanism, and described self-locking mechanism comprises slide, slide bar and backstay, and described slide is connected on mild steel damper; One end of described slide bar is connected with basis, and the other end is in slide and be slidably matched with it, and one end that described slide bar is positioned at slide has locating hole vertically; Described backstay and locating hole are axially parallel and be slidably matched with slide; During non-earthquake, described backstay is positioned at outside locating hole, and described mild steel damper is in free state, and during earthquake, described slide bar slides in slide, and described backstay enters in locating hole and mild steel damper and slide bar locked.When antidetonation, self-locking mechanism is connected with mild steel damper, make mild steel damper be in antidetonation stress, mild steel damper plays energy dissipating effect, but not during antidetonation, mild steel damper and self-locking mechanism depart from, mild steel damper is not by external force, and compare existing mild steel damper, the mild steel damper of this structure is when off working state, stressed little, effectively ensure that anti seismic efficiency during antidetonation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is elevation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the mechanical self-latching type mild metal damper of the present embodiment, comprise mild steel damper 1, also comprise self-locking mechanism 2, described self-locking mechanism 2 comprises slide 21, slide bar 22 and backstay 23, and described slide 21 is connected on mild steel damper 1; One end of described slide bar 22 is connected with the pedestal 16 be arranged on foundation of civil work, this pedestal 16 can be Ta Liang, Dun Liang junction of bridge, the other end of slide bar 22 is in slide 21 and be slidably matched with it, and one end that described slide bar 22 is positioned at slide has locating hole 24 vertically; Described backstay 23 and locating hole 24 are axially parallel and be slidably matched with slide 21; During non-earthquake, described backstay 23 is positioned at outside locating hole 24, and described mild steel damper 1 is in free state, and during earthquake, described slide bar 22 slides in slide 21, and described backstay 23 enters in locating hole 24 and mild steel damper 1 and slide bar 22 locked.When antidetonation, self-locking mechanism is connected with mild steel damper, makes mild steel damper and bearing be in connection status by slide bar, namely mild steel damper is in antidetonation stress, carry out stressed buffering to pedestal 16, mild steel damper plays energy dissipating effect, but not during antidetonation, mild steel damper and self-locking mechanism depart from, mild steel damper is not by external force, and compare existing mild steel damper, the mild steel damper of this structure is when off working state, stressed little, effectively ensure that anti seismic efficiency during antidetonation.
