Abstract
The utility model relates to a kind of picking spring bolt, comprise Connection Block and the first tongue block be symmetrical set and the second tongue block, the middle part of described first tongue block and the second tongue block is respectively arranged with axis hole, described Connection Block is provided with the pivot matched with the axis hole of the first tongue block and the second tongue block respectively, described first tongue block and the second tongue block can respectively around described pivot rotary setting, and one end of described first tongue block and the second tongue block is respectively arranged with outwardly fixture block.Technical solutions of the utility model, have the effect improving security door safety.
Description
Technical field
The utility model relates to a kind of picking spring bolt.
Background technology
Existing security door, its dead bolt all adopts rectilinear movement form to lock, and its pick-proof performance exists certain deficiency, thus safety can not effectively be ensured.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of picking spring bolt improving safety.
For achieving the above object, the utility model provides following technical scheme: a kind of picking spring bolt, comprise Connection Block and the first tongue block be symmetrical set and the second tongue block, the middle part of described first tongue block and the second tongue block is respectively arranged with axis hole, described Connection Block is provided with the pivot matched with the axis hole of the first tongue block and the second tongue block respectively, described first tongue block and the second tongue block can respectively around described pivot rotary setting, and one end of described first tongue block and the second tongue block is respectively arranged with outwardly fixture block.
By adopting technique scheme, during locking, first tongue block and the second tongue block stretch out simultaneously, and the first tongue block and the second tongue block pivot simultaneously, first tongue block is opened with second corresponding fixture block one end of tongue block, opened by two fixture blocks of the first tongue block and the second tongue block and realize blocking locking with the hole of doorframe, thus when dead bolt is prized, namely want dead bolt to carry out Direct Travel to move, dead bolt carries out angle stroke motion again, just can pry open dead bolt, therefore, effectively improve pick-proof performance, safety is protected further.
The utility model can be arranged further: described first tongue block and the second tongue block are respectively arranged with skewed slot, described Connection Block are provided with the locating shaft coordinated with described skewed slot respectively.
By adopting technique scheme, by coordinating of locating shaft and skewed slot, carrying out that can be more stable when making the first tongue block and the second tongue block opening and closing.
The utility model can be arranged further: described first tongue block is respectively arranged with reference column with the relative fixture block other end of the second tongue block.
By adopting technique scheme, coordinated with the housing of safe-guard door lock by reference column, when Connection Block is moved linearly, the first tongue block and the second tongue block can opening and closing.
The utility model can be arranged further: the limited block being respectively arranged with evagination outside the middle part of described first tongue block and the second tongue block.
By adopting technique scheme, being coordinated with the housing of safe-guard door lock by limited block, stroke being stretched out to the straight line of the first tongue block and the second tongue block and carries out spacing.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model example structure figure;
Fig. 2 is structural blast figure of the present utility model.
Detailed description of the invention
See accompanying drawing 1 and accompanying drawing 2, picking spring bolt disclosed in the utility model, the first tongue block 2 and the second tongue block 3 comprising Connection Block 1 and be symmetrical set, the middle part of described first tongue block 2 and the second tongue block 3 is respectively arranged with axis hole 201,301, described Connection Block 1 is provided with the pivot 101 matched with the axis hole 201,301 of the first tongue block 2 and the second tongue block 3 respectively, described first tongue block 2 and the second tongue block 3 can respectively around described pivot 101 rotary setting, and one end of described first tongue block 2 and the second tongue block 3 is respectively arranged with outwardly fixture block 202,302.By adopting technique scheme, during locking, first tongue block 2 and the second tongue block 3 stretch out simultaneously, and the first tongue block 2 and the second tongue block 3 pivotally 101 rotate simultaneously, make the first tongue block 2 and the corresponding fixture block 202 of the second tongue block 3, 302 one end are opened, by two fixture blocks 202 of the first tongue block 2 and the second tongue block 3, 302 open and realize blocking locking with the hole of doorframe, thus when dead bolt is prized, namely want dead bolt to carry out Direct Travel to move, dead bolt carries out angle stroke motion again, just dead bolt can be pried open, therefore, effectively improve pick-proof performance, safety is protected further.
The present embodiment is arranged further: described first tongue block 2 and the second tongue block 3 are respectively arranged with skewed slot 203,303, described Connection Block 1 is provided with and joins 203,303 locating shafts closed 102 with described skewed slot respectively.By adopting technique scheme, by coordinating of locating shaft 102 and skewed slot 203,303, carrying out that can be more stable when making the first tongue block 2 and the second tongue block 3 opening and closing.
The present embodiment is arranged further: described first tongue block 2 is respectively arranged with reference column 204,304 with the second tongue block 3 relative fixture block 202,302 other end.By adopting technique scheme, coordinated with the housing of safe-guard door lock by reference column 204,304, when Connection Block 1 is moved linearly, the first tongue block 2 and the second tongue block 3 can opening and closing.
The present embodiment is arranged further: the limited block 205,305 being respectively arranged with evagination outside the middle part of described first tongue block 2 and the second tongue block 3.By adopting technique scheme, being coordinated with the housing of safe-guard door lock by limited block 205,305, stroke being stretched out to the straight line of the first tongue block 2 and the second tongue block 3 and carries out spacing.
