Description
Technical field
The present invention relates to the explosion proof door technical field, especially relate to a kind of explosion proof door with device for pre-positioning.
Background technology
Consider for house security, explosion proof door becomes the necessity of present household.Usually, explosion proof door comprises doorframe and the door core that adopts the metal material preparation, and is provided with lockset between doorframe and door core.Wherein, lockset used mostly comprises and is positioned at the dead bolt on a core and is positioned at lockhole on doorframe.Safer when although such explosion proof door uses, because lockset is comparatively accurate, when locking a door, need to rely on door core and doorframe accurate combination and with dead bolt and lockhole aligning.Like this, in case slight deformation appears in doorframe and door core, namely can cause due to door core and accurately combination of doorframe, thus the phenomenon that dead bolt and lockhole can't be aimed at.Simultaneously, after explosion proof door service time is long, the situation of door core and doorframe matching loose can appear inevitably.
Summary of the invention
The purpose of this invention is to provide a kind of explosion proof door with device for pre-positioning, it has can assist dead bolt and lockhole to be in alignment preferably, and is difficult for loosening characteristics between doorframe and door core.
The technical solution adopted in the present invention is: have the explosion proof door of device for pre-positioning, comprise doorframe and door core, described doorframe is provided with locating slot, and the door core is provided with the location dead bolt, and this location dead bolt and locating slot match, and the inboard of this location dead bolt is provided with stage clip.
Described door core is provided with accommodation hole and support plate, and wherein, this location dead bolt and stage clip are positioned at this accommodation hole, and simultaneously, the medial extremity of this location dead bolt is bolted with adjustment screw, and the medial extremity of this adjustment screw withstands on support plate.
Described adjustment screw is provided with Anti-slip nut.
The advantage that compared to the prior art the present invention has is: can assist dead bolt and lockhole to be in alignment preferably, and be difficult for loosening between doorframe and door core.Explosion proof door with device for pre-positioning of the present invention improves for the alignment so of dead bolt and lockhole.Namely, door core and doorframe are in closed moment, and the location dead bolt has and enters the trend in locating slot and certainly be advanced into locating slot under the effect of stage clip, make a core and doorframe be in the position of setting, thereby dead bolt and lockhole only need not the accurate cooperation by means of door core and doorframe.Like this, namely side door core or doorframe have slight deformation, also can not affect the aligning of dead bolt and lockhole.Certainly, because the location dead bolt can be pressed in locating slot, thereby can prevent from loosening situation occurring between doorframe and door core.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is the front view (broken section) of embodiments of the invention;
Fig. 2 is that A-A of Fig. 1 is to view;
Fig. 3 is the B section enlarged drawing of Fig. 2.
The specific embodiment
Embodiment sees that Fig. 1 is to shown in Figure 3: have the explosion proof door of device for pre-positioning, comprise the doorframe 10 and the door core 20 that are hinged together.Certainly, be provided with lockset between door core 20 and doorframe 10, lockset comprises and is positioned at the dead bolt on a core 20 and is positioned at lockhole on doorframe 10.In the present invention, this doorframe 10 is provided with locating slot 11, and this core 20 is provided with location dead bolt 22, and this location dead bolt 22 and locating slot 11 match, and the inboard of this location dead bolt 22 is provided with stage clip 23.That is, the end of location dead bolt 22 can withstand in locating slot 11, is in suitable relative position thereby make between a core 20 and doorframe 10, is equivalent to carry out pre-determined bit before the accurate cooperation of door core 20 and doorframe 10.Certainly, stage clip 23 makes location dead bolt 22 have trend to outer displacement, and then makes location dead bolt 22 in a single day near locating slot 11, namely positions voluntarily in groove 11.Like this, the dead bolt of lockset and the aligning of lockhole mainly rely on the cooperation of location dead bolt 22 and locating slot 11, but not only by means of the accurate cooperation of door core 20 and doorframe 10.Simultaneously, be difficult for becoming flexible between doorframe 10 and door core 20.Need to prove: the shape of locating slot 11 and location dead bolt 22 can be multiple, such as: locating slot 11 can be the V-arrangement that vertically moves towards, and the end of the location dead bolt 22 of this moment can be taper.Locating slot 11 can be also the hole shape, and the end of the location dead bolt 22 of this moment can be spherical.
Optimize, this core 20 is provided with accommodation hole 21 and support plate 25.Certainly, support plate 25 is positioned at the inboard (i.e. a side of close door core inner) of accommodation hole 21.Wherein, this location dead bolt 22 and stage clip 23 are positioned at this accommodation hole 21, and simultaneously, the medial extremity of this location dead bolt 22 is bolted with adjustment screw 24, and the medial extremity of this adjustment screw 24 withstands on support plate 25.Like this, only need rotate adjustment screw 24, can regulate the extension elongation of location dead bolt 22, so can avoid between a core 20 and doorframe 10 excesssive gap or when too small cooperation to location dead bolt 22 and locating slot 11 impact.
Further, this adjustment screw 24 is provided with Anti-slip nut 241.That is, after regulating the length of adjustment screw 24, turn Anti-slip nut 241 makes it and locates dead bolt 22 close contacts, can avoid adjustment screw 24 to occur loosening.
Explosion proof door is widely used at present, and other structure and principle are same as the prior art, repeat no more here.
The above is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes manual of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
