Abstract
The electric locking device up and down of a kind of, comprise the door body be rotationally connected with doorframe, electric pushrod is provided with respectively in the upper and lower part of door body, the upper and lower side of door body is also furnished with the strip bolt of level respectively, each bolt and each electric pushrod correspondence are connected, in the respective side of doorframe upper and lower part, be equipped with groove, bolt and groove corresponding matching, form and close retaining mechanism.Two bolts of the present utility model can distinguish the both sides up and down of locking door, during closedown, upper-lower door sews locking and blocks, and bolt cannot be cut off, the crack between a door and its frame weak location also easily do not pried open, safety improves greatly, and the crack between a door and its frame up and down closed makes the dust-separation sound insulation value of door obviously improve.
Description
Technical field: the utility model relates to the locking device of a kind of door, particularly door.
Background technology: present many doors are all equipped with electric lock, use laborsaving convenience, but on the mechanical realization of locking device, generally all adopt the bolt of one or more horizontal type, and electric lock controls bolt one end and inserts in the corresponding aperture of doorframe.The bolt of horizontal type is likely cut off by instrument, or crack between a door and its frame position is likely pried open by force, and safety also needs to strengthen.Further, in order to opening and closing is smooth and easy, leave certain interval, affect closure between door body upper and lower side and doorframe, the effect of dust-separation sound insulation is undesirable.
Summary of the invention: for the deficiencies in the prior art, the utility model provides a kind of structural safety, the electric locking device up and down of the door that closure is good.
The utility model comprises the door body be rotationally connected with doorframe, electric pushrod is provided with respectively in the upper and lower part of door body, the upper and lower side of door body is also furnished with the strip bolt of level respectively, each bolt and each electric pushrod correspondence are connected, groove is equipped with in the respective side of doorframe upper and lower part, bolt and groove corresponding matching, form and close retaining mechanism.
Two bolts of the present utility model can distinguish the both sides up and down of locking door, during closedown, upper-lower door sews locking and blocks, and bolt cannot be cut off, the crack between a door and its frame weak location also easily do not pried open, safety improves greatly, and the crack between a door and its frame up and down closed makes the dust-separation sound insulation value of door obviously improve.
The utility model is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing illustrates: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the A-A section enlarged diagram of Fig. 1.
Fig. 3 is the locking state schematic diagram of Fig. 2.
Detailed description of the invention: as depicted in figs. 1 and 2, door body 1 and doorframe 2 are rotationally connected, electric pushrod 3 is provided with respectively in the upper and lower part of door body 1, the upper and lower side of door body 1 is also furnished with the strip bolt 4 of level respectively, each bolt 4 and each electric pushrod 3 correspondence are connected, in the respective side of doorframe 2 upper and lower part, be equipped with groove 5, bolt 4 and groove 5 corresponding matching, form and close retaining mechanism.In fact, the horizontal length of each bolt 4 can close to the width of door body 1, and can close crack between a door and its frame completely when locking like this, safety is higher, and dust-separation sound insulation value is better.
In the present embodiment, each bolt 4 correspondence is connected with several vertical push shafts 6, and the end of each vertical push shaft 6 is linked to be entirety by the connecting rod 7 of level, and middle part and the corresponding electric pushrod 3 of connecting rod 7 are connected.When electric pushrod 3 action, by connecting rod 7 and each vertical push shaft 6 by bolt 4 up or down part push the groove 5 of doorframe 2, as shown in Figure 3, can lock and close upper and lower crack between a door and its frame.When unblanking, electric pushrod 3 counteragent, each bolt 4 is retracted in a body 1.
